The present disclosure relates to a draw in and out apparatus and a cart apparatus transporting the same, and more particularly, to a draw in and out apparatus for easily drawing a circuit breaker into a distribution board or easily drawing it out from a distribution board, and a cart apparatus for transporting the same.
A distribution board refers to an apparatus that transmits electricity received from an external power source to the load according to the system or purpose. The distribution board is energized with an external power source and load, respectively, and energizes the external power source and load.
To prevent power failures that may occur between external power sources and loads, distribution boards are usually equipped with circuit breakers. The circuit breaker is configured to be energizably connected to an external power source and load, respectively, and to cut off abnormal current when it occurs. Accordingly, the above power accident can be prevented.
If a current breaking operation is performed, replacement of the circuit breaker's components may be required. It can also be assumed that the circuit breaker must be removed from the distribution board for maintenance of the circuit breaker. Thus, it is common for the circuit breaker to be detachably coupled to the distribution board.
Meanwhile, the size of the distribution board and circuit breaker tends to be proportional to its rated capacity. That is, when a larger current is applied, the size of the circuit breaker for breaking it may increase. Accordingly, the size of the distribution board to which the circuit breaker is coupled may also be increased. Therefore, a large force is required for the circuit breaker to be coupled to or separated from the distribution board.
However, in the case of traditional structure distribution boards and circuit breakers, the process of connecting and disconnecting the circuit breakers is performed manually. That is, the above process is usually performed by an operator. Therefore, the accuracy and efficiency of the circuit breaker's connecting and disconnecting operations may be reduced. Furthermore, it is difficult to rule out the possibility of a safety accident occurring during the process of connecting and disconnecting heavy circuit breakers.
Korean Registered Patent Document No. 10-1733705 discloses a distribution board equipped with a vacuum circuit breaker draw in and out safety apparatus. Specifically, it discloses a distribution board equipped with a vacuum circuit breaker draw in and out safety apparatus, which has a locking groove provided on the bottom of a transport truck on which a vacuum circuit breaker is seated, and prevents arbitrary movement of the vacuum circuit breaker by locking or releasing the locking groove by a horizontal plate provided on a cradle.
However, the distribution board equipped with a vacuum circuit breaker draw in and out safety apparatus disclosed in the above-mentioned prior document assumes that the vacuum circuit breaker is manually drawn in and out from the distribution board. That is, the above prior document does not present a method for automatically performing the draw in and out process of a vacuum circuit breaker.
Korean Registered Patent Document No. 10-1912449 discloses a high-voltage distribution board with a remote racking system applied. Specifically, it discloses a high voltage distribution board having a remote racking system applied thereto, which enables draw in and out of circuit breakers within the high voltage distribution board in a remote form.
However, the high-voltage distribution board to which the remote racking system is applied, disclosed in the above-mentioned prior art document must have an actuator for moving the circuit breaker installed within the high-voltage distribution board. That is, additional motors are installed inside high-voltage distribution boards that include complex and diverse configurations, and additional complex wiring structures are required to control them.
Furthermore, the remote racking system disclosed in the above prior art document has complexly configured conditions for moving the circuit breaker. Therefore, since the control signal for the draw in or out of the circuit breaker must be input precisely, it is difficult for the draw in or out process of the circuit breaker to be performed smoothly.
The present disclosure is to solve the above problems, and the present disclosure is directed to providing a draw in and out apparatus having a structure that facilitates the drawing in and out process of a circuit breaker for a distribution board, and a cart apparatus for transporting the same.
The present disclosure is also directed to providing a draw in and out apparatus having a structure that is easy to move and install, and a cart apparatus for transporting the same.
The present disclosure is also directed to providing a draw in and out apparatus having a structure in which heavy components can be stored or moved separately, and a cart apparatus for transporting the same.
The present disclosure is also directed to providing a draw in and out apparatus having a structure that can be easily coupled to or separated from a distribution board, and a cart apparatus for transporting the same.
The present disclosure is also directed to providing a draw in and out apparatus having a structure in which the drawing in and out process of a circuit breaker can be performed remotely, and a cart apparatus for transporting the same.
The present disclosure is also directed to providing a draw in and out apparatus having a structure whose size can be changed to correspond to a distribution board or a circuit breaker, and a cart apparatus for transporting the same.

In addition, a draw in and out apparatus may be provided in which the first support unit includes a handle member coupled to the magnet member and configured to adjust the magnitude of a magnetic force formed by the magnet member by being operated by an external force.
In this case, a draw in and out apparatus may be provided in which when the handle member is rotated in any one direction of the clockwise direction and the counterclockwise direction, the magnitude of the magnetic force formed by the magnet member increases, so that the magnet member is coupled to the distribution board, and when the handle member is rotated in the other direction of the clockwise direction and the counterclockwise direction, the magnitude of the magnetic force formed by the magnet member decreases, so that the magnet member is separated from the distribution board.
In addition, a draw in and out apparatus may be provided in which a pair of said column members are provided, and the pair of column members are disposed to be spaced apart from each other, and the plate member is formed to extend as far as a distance at which the pair of column members are spaced apart.
In this case, a draw in and out apparatus may be provided in which the second support unit includes a partition wall member movably coupled to the column member; and a beam member that is coupled to the partition wall member to move together with the partition wall member and movably supports the third support unit.
In addition, a draw in and out apparatus may be provided in which a pair of said beam members are provided, and the pair of beam members are disposed to be spaced apart from each other, and the partition wall member is formed to extend as far as a distance at which the pair of beam members are spaced apart.
In this case, a draw in and out apparatus may be provided in which the third support unit includes a bar member movably coupled to the beam member and extending in a direction opposite to the circuit breaker; and a support member coupled to an end in the extension direction of the bar member.
In addition, a draw in and out apparatus may be provided in which a pair of said bar members are provided, and the pair of bar members are disposed to be spaced apart from each other, and the support member is formed to extend as far as a distance at which the pair of bar members are spaced apart.
In addition, according to an aspect of the present disclosure, provided is a cart apparatus configured to be moved with loading a plurality of support units and a power unit that is detachably coupled to one of the plurality of support units, the cart apparatus including a cart body: a support plate forming one side of the cart body and supporting the power unit; and an apparatus support portion formed to extend outward from the other side of the cart body and penetrate through the plurality of support units coupled to each other to support a portion thereof.
In this case, a cart apparatus may be provided in which the power unit includes a motor member; a key coupled to the motor member to rotate together; and a remote controller configured to be energized with the motor member and to receive a control signal, and a utility accommodation portion in which a plurality of openings are formed through which the motor member, the key, and the remote controller pass, respectively, is disposed in the support plate.
According to the above configuration, the draw in and out apparatus and the cart apparatus including the same according to an exemplary embodiment of the present disclosure can facilitate the drawing in and out process of the circuit breaker to the distribution board.
The draw in and out apparatus is equipped with a power unit. The power unit is equipped with a motor member that is rotated by an external power source. The motor member includes a shaft and a key coupled to the shaft and rotated together. The key can be accommodated in or drawn out from an insertion space formed in the circuit breaker.
When the motor member is operated, the key is rotated clockwise or counterclockwise while being accommodated in the insertion space. Accordingly, members provided adjacent to the insertion space of the circuit breaker are rotated together, so that the circuit breaker can be drawn into or drawn out from the distribution board.
Therefore, the process of drawing in and out of the circuit breaker can be performed by the operation of the power unit. As a result, the process of coupling and separating the circuit breaker and the distribution board may proceed even if manual work of an operator is not involved.
In addition, according to the above configuration, the draw in and out apparatus and the cart apparatus including the same according to an exemplary embodiment of the present disclosure can be easily moved and installed.
Each component of the draw in and out apparatus can be detachably coupled. In particular, the power unit formed to have a high weight is detachably coupled to the third support unit and can be moved together with the third support unit. Specifically, the power unit is fixedly coupled to the adjustment member, and the adjustment member is movably coupled to the bar member. Accordingly, the power unit can be moved along the bar member.
Therefore, when the draw in and out apparatus is moved, other components of the draw in and out apparatus and the power unit can be moved separately from each other. In this case, the cart apparatus provided to transport the draw in and out apparatus is provided separately with a part accommodating the other components above and a part accommodating the power unit.
Furthermore, when the draw in and out apparatus is installed on the distribution board, other components other than the power unit can be installed on the distribution board first, and then the power unit can be coupled to the adjustment member. Therefore, it is not necessary to install a high-weight power unit at the same time, and thus ease of installation can be increased.
In addition, according to the above configuration, in the draw in and out apparatus and the cart apparatus including the same according to an exemplary embodiment of the present disclosure, heavy components can be stored or moved separately.
As described above, the high-weight power unit is provided detachably from the draw in and out apparatus. The cart apparatus includes a support plate and a utility accommodation portion for separately accommodating each component of the power unit, that is, the motor member, the key, the control device, and the remote controller.
Furthermore, the cart apparatus includes an apparatus support portion and an apparatus coupling portion for supporting other components except for the power unit among the components of the draw in and out apparatus.
Therefore, high-weight components among the components of the draw in and out apparatus can be separately managed, making it easier to move, assemble, and maintain the draw in and out apparatus.
In addition, according to the above configuration, the draw in and out apparatus and the cart apparatus including the same according to an exemplary embodiment of the present disclosure can be easily coupled to or separated from the distribution board.
The draw in and out apparatus includes a magnet member for forming a magnetic force. The magnitude of the magnetic force formed by the magnet member can be adjusted by the handle member. That is, as the handle member is operated by an external force, the magnitude of the magnetic force can be adjusted.
A plurality of magnet members can be provided. The plurality of magnet members can be disposed at different positions, so that the draw in and out apparatus can be coupled to the distribution board at a plurality of positions.
As described above, the high-weight power unit is detachably provided. Therefore, after other components except for the high-weight power unit are coupled to the distribution board by the magnet member, the power unit can be provided in the draw in and out apparatus.
When the power unit is operated after being coupled to the circuit breaker, the circuit breaker can be drawn into or drawn out from the distribution board.
In the case of separating the draw in and out apparatus, the high-weight power unit can be separated first, and then the other components can be separated from the distribution board. In this case, the magnitude of the magnetic force formed by the magnet member by operating the handle member is also adjusted so that the draw in and out apparatus and the distribution board can be separated.
Therefore, the draw in and out apparatus can be easily coupled to or separated from the distribution board.
In addition, according to the above configuration, the draw in and out apparatus and the cart apparatus including the same according to an exemplary embodiment of the present disclosure can remotely proceed with the drawing in and out process of the circuit breaker.
The power unit includes a remote controller energized with the motor member. The remote controller is energized with the motor member through the control device. An operator can control the operation of the motor member by inputting a control signal to the remote controller while being spaced apart from the power unit.
Therefore, the drawing in and out process of the circuit breaker can be performed by an operator physically spaced apart from the circuit breaker. As a result, any safety accidents that may occur during the drawing in and out process of the circuit breaker can be prevented.
In addition, according to the above configuration, the size of the draw in and out apparatus and the cart apparatus including the same according to an exemplary embodiment of the present disclosure can be changed to correspond to the distribution board or the circuit breaker.
The draw in and out apparatus includes a plurality of support units movably coupled to each other. The plurality of support units include a plurality of column members, a plurality of beam members, and a plurality of bar members extending in different directions.
The plurality of column members are positioned adjacent to each other, but the separation distance thereof can be adjusted. A plate member extending corresponding to the separation distance are coupled to the plurality of column members to support the plurality of column members spaced apart from each other.
The plurality of beam members are positioned adjacent to each other, but the separation distance thereof can be adjusted. A partition wall member extending corresponding to the separation distance are coupled to the plurality of beam members to support the plurality of beam members spaced apart from each other.
The plurality of bar members are positioned adjacent to each other, but the separation distance thereof can be adjusted. A support member extending corresponding to the separation distance are coupled to the plurality of bar members to support the plurality of bar members spaced apart from each other.
Therefore, the size of the draw in and out apparatus can be adjusted by the separation distance between the plurality of column members, the plurality of beam members, and the plurality of bar members. As a result, the size of the draw in and out apparatus can be adjusted to correspond to the size of the distribution board or circuit breaker to which it is coupled by adjusting the separation distance between each of the above-mentioned members.

A circuit breaker 20 provided in a distribution board 10 according to an exemplary embodiment of the present disclosure may be configured to perform a breaking operation to break energization between a power supply source and a load when an abnormal current is detected.
The terms “above or upper side”, “below or lower side”, “left side”, “right side”, “front side”, and “rear side” used in the following description will be understood with reference to the coordinate system shown in
Referring to
In this case, the circuit breaker 20 is withdrawably accommodated in the distribution board 10. The distribution board 10 and the circuit breaker 20 may be energizably connected to each other, and as a result, the circuit breaker 20 may be energizably connected to an external power source (not shown) and an external load (not shown), respectively. Therefore, current or power transmitted from the external power source (not shown) can be transmitted to the external load (not shown) after passing through the circuit breaker 20.
Therefore, when an abnormal current is detected, the circuit breaker 20 may perform a breaking operation to prevent damage to an external load (not shown) or a power accident.
The distribution board 10 may accommodate the circuit breaker 20 so as to be withdrawable and may be provided in an arbitrary shape that can be energized with an external power source (not shown) and an external load (not shown), respectively. In the illustrated embodiment, the distribution board 10 has a rectangular parallelepiped shape having a length in the front-rear direction, a width in the left-right direction, and a height in the up-down direction.
In the above embodiment, a plurality of distribution boards 10 may be provided and disposed in parallel in the width direction, that is, in the left-right direction in the illustrated embodiment, so that the amount of power to be energized may be increased.
In the illustrated embodiment, the distribution board 10 includes a distribution board housing 11 and an insertion space 12.
The distribution board housing 11 forms the outer shape of the distribution board 10. A space is formed inside the distribution board housing 11 so that various configurations for performing functions of the distribution board 10 may be mounted. In this case, the circuit breaker 20 may also be withdrawably accommodated in the space of the distribution board housing 11.
In the illustrated embodiment, an opening (reference numeral not indicated) that communicates with the space and functions as a passage through which the circuit breaker 20 is drawn in or out is formed on the front side of the distribution board housing 11. In the illustrated embodiment, the opening is formed to have a quadrangular cross-section corresponding to the shape of the circuit breaker 20.
The opening is surrounded by the insertion space 12.
The insertion space 12 is a portion where a draw in and out apparatus 30 according to an exemplary embodiment of the present disclosure is coupled to the distribution board 10. The draw in and out apparatus 30 is formed to surround the opening from the outside. In the illustrated embodiment, the draw in and out apparatus 30 has a quadrangular shape corresponding to the shape of the cross-section of the opening formed in a quadrangular shape.
The insertion space 12 may protrude from one side surface of the surfaces of the distribution board housing 11, from which the circuit breaker 20 is drawn in or out, that is, from the front side surface in the illustrated embodiment. Therefore, an operator can easily identify the insertion space 12 and couple the draw in and out apparatus 30 to the distribution board housing 11 to correspond to the location of the insertion space 12.
The circuit breaker 20 is withdrawably accommodated in the distribution board 10. In other words, the circuit breaker 20 may be drawn into the distribution board 10 and energizably connected with the components of the distribution board 10, an external power source (not shown), and an external load (not shown), respectively. In addition, the circuit breaker 20 may be drawn out from the distribution board 10 so that the energization state may be released.
The circuit breaker 20 may be drawn into the inner space of the distribution board housing 11 through the opening formed on the one side surface of the distribution board housing 11, that is, on the front side surface in the illustrated embodiment. To this end, the opening is formed to have a quadrangular cross-section corresponding to the shape of the circuit breaker 20, as described above.
When an abnormal current is detected, a process in which the circuit breaker 20 is operated to perform the breaking operation is a well-known technology, and thus a detailed description thereof will be omitted.
The circuit breaker 20 coupled to the distribution board housing 11 may be partially exposed outwardly. In addition, a portion of the circuit breaker 20 exposed to the outside may be disposed to be surrounded by the insertion space 12. In the illustrated embodiment, one surface of the front side of the circuit breaker 20 is exposed outwardly and is disposed to be surrounded by the insertion space 12.
A plurality of circuit breakers 20 may be provided. The plurality of circuit breakers 20 may be physically and electrically spaced apart from each other to be energizably connected with the components of the distribution board 10, an external power source (not shown), and an external load (not shown), respectively.
In the illustrated embodiment, four circuit breakers 20 are provided and disposed to be spaced apart from each other in the height direction of the distribution board 10, that is, in the up-down direction. The number and arrangement method of the circuit breakers 20 may be changed according to the magnitude of the electric current or electric power and the shape of the distribution board 10.
In the illustrated embodiment, the circuit breaker 20 includes a break button 21 and an apparatus insertion portion 22.
The break button 21 is a portion that is operated in advance so that the circuit breaker 20 can be drawn out. When the break button 21 is operated, the coupling state of the circuit breaker 20 and the distribution board 10 is released. In other words, as the break button 21 is operated, the circuit breaker 20 coupled to the distribution board 10 may be in a state that can be drawn out from the distribution board housing 11.
In addition, when the circuit breaker 20 is accommodated in the distribution board housing 11, the distribution board 10 and the circuit breaker 20 may be combined as the break button 21 is operated. In other words, as the break button 21 is operated, the circuit breaker 20 that was drawn in is not arbitrarily drawn out from the distribution board housing 11.
The break button 21 may be provided in an arbitrary form capable of forming or releasing a coupling state between the circuit breaker 20 and the distribution board 10. In the illustrated embodiment, the break button 21 is provided in the form of a button capable of performing the above operation by pressing the same. In the above embodiment, the break button 21 may be provided as a toggle button, and may be configured to form or release a coupling state between the circuit breaker 20 and the distribution board 10 according to the number of times of pressing.
As will be described later, before the draw in and out apparatus 30 according to an exemplary embodiment of the present disclosure is disposed in the insertion space 12, the break button 21 may be operated in advance. Alternatively, the break button 21 may be operated later after the draw in and out apparatus 30 is disposed in the insertion space 12. In either case, it is sufficient if the break button 21 can be pre-operated before the draw in and out apparatus 30 is operated.
The break button 21 is located at a lower side of one side surface where the circuit breaker 20 accommodated in the distribution board housing 11 is exposed to the outside, that is, the front side surface in the illustrated embodiment. The apparatus insertion portion 22 is disposed adjacent to the break button 21.
The apparatus insertion portion 22 is a portion to which a power unit 500 provided in the draw in and out apparatus 30 is coupled. A key 540 of the power unit 500 may be rotated while inserted into the apparatus insertion portion 22 to completely release the coupling state between the circuit breaker 20 and the distribution board housing 11.
The apparatus insertion portion 22 is located adjacent to the break button 21. In the illustrated embodiment, the apparatus insertion portion 22 is located at a lower side of the one side surface where the circuit breaker 20 accommodated in the distribution board housing 11 is exposed to the outside, that is, the front side surface.
The apparatus insertion portion 22 may be formed in a shape corresponding to the shape of the key 540. In this case, the apparatus insertion portion 22 may be formed to include at least one portion having an asymmetrical cross-section.
Therefore, the key 540 may be inserted into the apparatus insertion portion 22 only in a preset direction. Furthermore, when the inserted key 540 is rotated, the circuit breaker 20 may be drawn into the distribution board housing 11 drawn out from the distribution board housing 11 by rotation of a screw (not shown) or the like coupled to the apparatus insertion portion 22 by the asymmetric portion above.

In this case, the draw in and out apparatus 30 is equipped with a power unit 500, so that the draw in or out process of the circuit breaker 20 may be performed without operation by an operator.
Furthermore, the draw in and out apparatus 30 according to an exemplary embodiment of the present disclosure may be provided so that each component can be separated. In this case, each of the above components is movably coupled to each other so that the position at which the draw in and out apparatus 30 is coupled to the circuit breaker 20 may be varied. Furthermore, in the draw in and out apparatus 30, each component may be moved to a working position, assembled at the working position, and then coupled to the circuit breaker 20.

The draw in and out apparatus 30 covers the circuit breaker 20 exposed through the opening of the distribution board housing 11 and is coupled to the distribution board housing 11. In this case, as will be described later, an accommodation opening 130 is formed to be open inside the draw in and out apparatus 30. Therefore, it may be said that the draw in and out apparatus 30 is coupled to the distribution board housing 11 so that the accommodation opening 130 and the circuit breaker 20 overlap each other.
The draw in and out apparatus 30 is detachably coupled to the circuit breaker 20. The key 540 provided in the draw in and out apparatus 30 may be inserted into and coupled to the apparatus insertion portion 22 of the circuit breaker 20. When the motor member 510 of the power unit 500 is operated, the key 540 is rotated while inserted into the apparatus insertion portion 22, so that the circuit breaker 20 may be drawn into the distribution board housing 11 or drawn out from the distribution board housing 11.
The draw in and out apparatus 30 may be detachably coupled to the distribution board 10 and the circuit breaker 20, respectively, and may be provided in any form in which the circuit breaker 20 can be drawn into the distribution board housing 11 or drawn out from the distribution board housing 11.
A plurality of draw in and out apparatuses 30 may be provided. The plurality of draw in and out apparatuses 30 may be detachably respectively coupled to a plurality of circuit breakers 20 coupled to the distribution board 10. In this case, it will be understood that the plurality of draw in and out apparatuses 30 may be detachably coupled to the one side surface of the distribution board housing 11, that is, the front side surface in the illustrated embodiment.
The draw in and out apparatus 31 according to an exemplary embodiment of the present disclosure and the draw in and out apparatus 32 according to another exemplary embodiment of the present disclosure, which will be described below, have some differences in the structure of the configuration, but the coupling structure and function of the distribution board 10 and the circuit breaker 20 described above are the same. Accordingly, in the case of a common description in the following description, the draw in and out apparatuses 31 and 32 will be collectively referred to as the draw in and out apparatus 30.
Referring to
The draw in and out apparatus 31 according to an exemplary embodiment of the present disclosure may be detachably coupled to the distribution board 10. As will be described later, the coupling and removal of the draw in and out apparatus 31 and the distribution board 10 may be achieved by a magnetic force applied by the magnet member 140 provided in the draw in and out apparatus 31.
The draw in and out apparatus 31 according to an exemplary embodiment of the present disclosure may be detachably coupled to the circuit breaker 20. As will be described later, the coupling and removal of the draw in and out apparatus 31 and the circuit breaker 20 may be achieved by withdrawably inserting the key 540 into the apparatus insertion portion 22 of the circuit breaker 20.
Various components of the draw in and out apparatus 31 to be described later may be detachably coupled to each other. In particular, the power unit 500 formed by a high weight can be detachably provided, so that the movement and installation of the draw in and out apparatus 31 can be easily carried out.
The draw in and out apparatus 31 may be formed in a shape corresponding to the shape of the distribution board housing 11 and the circuit breaker 20 to be coupled thereto. In the illustrated embodiment, the distribution board housing 11 and the circuit breaker 20 are each formed to have a quadrangular cross-section, and the draw in and out apparatus 31 may also have a quadrangular cross-section in the vertical direction.

The first support unit 100 may be formed in an outer shape corresponding to the shape of the distribution board 10 or the circuit breaker 20. In the illustrated embodiment, the first support unit 100 is formed to have a quadrangular cross-section having a width in the left-right direction and a height in the up-down direction.

The first support unit 100 forms a path through which the other components of the draw in and out apparatus 31 move along the first axis a1 (see
According to the above-described coupling relationship, it may be said that the first support unit 100 movably supports the second support unit 200, the third support unit 300, and the power unit 500 along the first axis a1.
The first support unit 100 is coupled to the coupling unit 400. Various components of the first support unit 100 may be fixedly coupled to each other by a first coupling unit 410. In addition, the first support unit 100 and the second support unit 200 may be movably coupled by a second coupling unit 420.
In the embodiment shown in

The column member 110 is formed to extend in one direction, that is, in the up-down direction in the illustrated embodiment, to form an outer shape in the width direction of the first support unit 100. As will be described later, the column member 110 functions as the first axis a1 for movably supporting the second support unit 200. Therefore, it may be said that the column member 110 extends along the first axis a1.
The column member 110 may be formed of a lightweight yet highly rigid material. This is to stably maintain the shape and coupling state of the draw in and out apparatus 31, and to movably and stably support the second support unit 200 and other components coupled to the second support unit 200.
The column member 110 may be formed of an electrically insulating material. In addition, the column member 110 may be formed of a material that is not magnetized by magnetic force.

In an embodiment, the column member 110 may be formed of aluminum (Al) or an alloy material including aluminum.

In the illustrated embodiment, two column members 110 are provided, including a first column member 111 disposed on the left and coupled to the plate member 120 and the second support unit 200, respectively, and a second column member 112 disposed on the right and coupled to the plate member 120 and the second support unit 200, respectively. The first column member 111 and the second column member 112 are disposed to face each other with the accommodation opening 130 interposed therebetween, and surround the accommodation opening 130 in the width direction, that is, in the left-right direction in the illustrated embodiment.

The other end in the extension direction of the first column member 111, that is, the lower end in the illustrated embodiment, is fixedly coupled to the second plate member 122. The coupling may also be achieved by the first coupling unit 410.
A first column hollow 111a is formed inside the first column member 111. The outer side of the first column hollow 111a is formed to be open and communicates with the outside. The second coupling unit 420 may be inserted into and coupled to the first column hollow 111a. Accordingly, the second support unit 200 may be coupled to the first column member 111 by the second coupling unit 420.
The first column hollow 111a is formed to extend in the extension direction of the first column member 111, that is, in the up-down direction in the illustrated embodiment, and each end of the extension direction, that is, the upper end and the lower end, is formed to be open. Therefore, the second coupling unit 420 accommodated in the first column hollow 111a and the second support unit 200 coupled thereto may be moved along the extension direction of the first column hollow 111a.
A plurality of first column hollows 111a may be provided. The plurality of first column hollows 111a may be formed on different side surfaces of the first column member 111, respectively. In the illustrated embodiment, four first column hollows 111a are formed on the front, rear, left and right side surfaces of the first column member 111, respectively.

The second column member 112 is formed to extend in the height direction of the first support unit 100, that is, in the up-down direction in the illustrated embodiment.
One end in the extension direction of the second column member 112, that is, the upper end in the illustrated embodiment, is fixedly coupled to the first plate member 121. The coupling may be achieved by the first coupling unit 410.
The other end in the extension direction of the second column member 112, that is, the lower end in the illustrated embodiment, is fixedly coupled to the second plate member 122. The coupling may also be achieved by the first coupling unit 410.
A second column hollow 112a is formed inside the second column member 112. The outer side of the second column hollow 112a is formed to be open and communicates with the outside. The second coupling unit 420 may be inserted into and coupled to the second column hollow 112a. Accordingly, the second support unit 200 may be coupled to the second column member 112 by the second coupling unit 420.
The second column hollow 112a is formed to extend in the extension direction of the second column member 112, that is, in the up-down direction in the illustrated embodiment, and each end of the extension direction, that is, the upper end and the lower end, is formed to be open. Therefore, the second coupling unit 420 accommodated in the second column hollow 112a and the second support unit 200 coupled thereto may be moved along the extension direction of the second column hollow 112a.
A plurality of second column hollows 112a may be provided. The plurality of second column hollows 112a may be formed on different side surfaces of the second column member 112, respectively. In the illustrated embodiment, four second column hollows 112a are formed on the front, rear, left and right side surfaces of the second column member 112, respectively.
A distance at which the first column member 111 and the second column member 112 are spaced apart from each other may be defined as a first separation distance d1 (see
In addition, the first separation distance d1 may be defined as a distance by which the third support unit 300 and the power unit 500 coupled to the second support unit 200 can be moved along the width direction, that is, the second axis a2 (see
In this case, the first separation distance d1 may be changed to correspond to the shape of the distribution board 10 or the circuit breaker 20. Therefore, the length in the width direction of the first support unit 100, that is, the length in a direction along the first axis a1 may be varied. As a result, the draw in and out apparatus 31 may actively correspond to the distribution board 10 or the circuit breaker 20 of various sizes.
The plate member 120 forms another part of the body of the first support unit 100. The plate member 120 is formed to extend in the other direction, that is, in the left-right direction in the illustrated embodiment, to form an outer shape in the height direction of the first support unit 100.
The plate member 120 may limit a movement distance in a direction along the first axis a1 of the second support unit 200. That is, the second support unit 200 coupled to the column member 110 may be moved along the first axis a1 until it contacts the plate member 120.
The plate member 120 may be formed of a lightweight yet highly rigid material. This is to stably maintain the shape of the first support unit 100 and the coupling state with the column member 110.
The plate member 120 may be formed of an electrically insulating material. In addition, the plate member 120 may be formed of a material that is not magnetized by magnetic force. This is to prevent a situation in which the magnetic force for this is weakened or disturbed when the first support unit 100 is coupled to the distribution board housing 11 by the magnet member 140.
In an embodiment, the plate member 120 may be formed of aluminum (Al) or an alloy material including aluminum.
As the name indicates, the plate member 120 may be provided in a plate shape. An end in the longitudinal direction of the plate member 120 may be fixedly coupled to the column member 110 by the first coupling unit 410.
The plate member 120 is coupled to the column member 110. The plate member 120 is configured to support the column member 110 in the longitudinal direction. In the illustrated embodiment, the plate member 120 is coupled to ends in the up-down direction of the column member 110.
In an embodiment in which a plurality of column members 110 are provided, the plate member 120 may be coupled to a plurality of column members 110, respectively. In the illustrated embodiment, one end in the extension direction of the plate member 120, that is, the left end, is coupled to the first column member 111 located on the left side. The other end in the extension direction of the plate member 120, that is, the right end, is coupled to the second column member 112 located on the right side.
A plurality of plate members 120 may be provided. The plurality of plate members 120 may be disposed to be spaced apart from each other and coupled to different portions of the column member 110, respectively. In addition, the plurality of plate members 120 may be disposed to face each other with the second support unit 200 interposed therebetween.
In the illustrated embodiment, two plate members 120 are provided, including a first plate member 121 disposed at the upper side and coupled to the column member 110 and a second plate member 122 disposed at the lower side and coupled to the column member 110. The first plate member 121 and the second plate member 122 are disposed to face each other with the accommodation opening 130 interposed therebetween, and surround the accommodation opening 130 in the height direction, that is, in the up-down direction in the illustrated embodiment.
The first plate member 121 forms one side in the height direction of the first support unit 100, that is, the upper side in the illustrated embodiment. The first plate member 121 is formed to extend in the width direction of the first support unit 100, that is, in the left-right direction in the illustrated embodiment.
One end in the extension direction of the first plate member 121, that is, the left end in the illustrated embodiment, is fixedly coupled to the first column member 111. The coupling may be achieved by the first coupling unit 410.
The other end in the extension direction of the first plate member 121, that is, the right end in the illustrated embodiment, is fixedly coupled to the second column member 112. The coupling may be achieved by the first coupling unit 410.
The first plate member 121 is coupled to the magnet member 140 and the gripping member 160 to support them. In an embodiment in which a plurality of magnet members 140 are provided, the first plate member 121 may support a first magnet member 141 and a third magnet member 143 positioned on the upper side.
The first plate member 121 may be formed to have a predetermined thickness, that is, a length in the up-down direction in the illustrated embodiment. The thickness of the first plate member 121 may be defined as a first thickness t1.
The first plate member 121 is disposed to face the second plate member 122 with the accommodation opening 130 interposed therebetween.
The second plate member 122 forms the other side in the height direction of the first support unit 100, that is, the lower side in the illustrated embodiment. The second plate member 122 is formed to extend in the width direction of the first support unit 100, that is, in the left-right direction in the illustrated embodiment.
One end in the extension direction of the second plate member 122, that is, the left end in the illustrated embodiment, is fixedly coupled to the first column member 111. The coupling may be achieved by the first coupling unit 410.
The other end in the extension direction of the second plate member 122, that is, the right end in the illustrated embodiment, is fixedly coupled to the second column member 112. The coupling may be achieved by the first coupling unit 410.
The second plate member 122 is coupled to the magnet member 140. In an embodiment in which a plurality of magnet members 140 are provided, the second plate member 122 may support a second magnet member 142 positioned on the lower side from the upper side. By the above arrangement, the accommodation opening 130 may be formed to have a quadrangular cross-section corresponding to the shape of the insertion space 12 or the circuit breaker 20.
The second plate member 122 may be formed to have a predetermined thickness, that is, a length in the up-down direction in the illustrated embodiment. The thickness of the second plate member 122 may be defined as a second thickness t2.
In this case, the first thickness t1 of the first plate member 121 may be greater than or equal to the second thickness t2 of the second plate member 122. This is because the first plate member 121 is configured to support a plurality of magnet members 140, and higher rigidity than the second plate member 122 is required.
This is also to ensure sufficient durability when an operator moves the first support unit 100 through the gripping member 160, as the first plate member 121 is coupled to the gripping member 160.
A space formed surrounded by the plurality of column members 110 and the plurality of plate members 120 may be defined as an accommodation opening 130.
The accommodation opening 130 is a space in which the circuit breaker 20 coupled to the draw in and out apparatus 31 is exposed to the outside. The accommodation opening 130 has one side opposite to the circuit breaker 20, i.e., the front side in the illustrated embodiment and the other side toward the circuit breaker 20, i.e., the rear side in the illustrated embodiment, respectively, formed to be open.
Accordingly, the third support unit 300 and the power unit 500 coupled to the second support unit 200 may be moved in a direction toward the circuit breaker 20 (i.e., the front side) or a direction opposite to the circuit breaker 20 (i.e., the rear side) along the third axis a3 (see
The second support unit 200 is movably located in the accommodation opening 130. Accordingly, it will be understood that the third support unit 300 and the power unit 500 coupled to the second support unit 200 are also movably located in the accommodation opening 130. In the illustrated embodiment, the second support unit 200, the third support unit 300, and the power unit 500 are disposed to cover the accommodation opening 130 from the outside, that is, from the front side.
A distance by which the second support unit 200 located in the accommodation opening 130 may be moved along the first axis a1 may be limited by the first plate member 121 and the second plate member 122. That is, the second support unit 200 may be moved along the first axis a1 until it contacts the first plate member 121 or the second plate member 122.
A distance by which the third support unit 300 coupled to the second support unit 200 located in the accommodation opening 130 may be moved along the second axis a2 may be limited by the first column member 111 and the second column member 112. That is, the distance that the third support unit 300 coupled to the second support unit 200 is moved along the second axis a2 may be determined according to the first separation distance d1, which is a distance between the first column member 111 and the second column member 112.
The accommodation opening 130 may have any shape in which the second support unit 200, the third support unit 300 and the power unit 500 coupled thereto may be moved along any one or more of the first axis a1, the second axis a2, and the third axis a3. In the illustrated embodiment, the accommodation opening 130 is formed to have a quadrangular cross-section surrounded by the column member 110 in the left-right direction and by the plate member 120 in the up-down direction.
The magnet member 140 is a portion where the first support unit 100 is coupled to the distribution board housing 11. The magnet member 140 may be controlled to form or release a magnetic force by operating the handle member 150. The first support unit 100 and the distribution board housing 11 may be maintained in a coupled state by a magnetic force formed by the magnet member 140. That is, the first support unit 100 is detachably coupled to the distribution board housing 11 by a magnetic force.
It is preferable that the magnetic force formed by the magnet member 140 does not act on other components of the draw in and out apparatus 31. This is due to the possibility that the formed magnetic force is disturbed or weakened, and thus the coupling force between the magnet member 140 and the distribution board housing 11 is weakened.
Accordingly, as described above, the column member 110 and the plate member 120 positioned adjacent to the magnet member 140 may be formed of a material that is not magnetized, for example, a material such as aluminum. In addition, as will be described later, some or all of the components of the second support unit 200, the third support unit 300, the coupling unit 400, and the power unit 500 may also be formed of the above material.
Accordingly, the magnetic force formed by the magnet member 140 may not be transferred to other components and may be formed to be applied to the distribution board housing 11.
The magnet member 140 is coupled to the plate member 120. The magnet member 140 is supported by the plate member 120. In this case, the magnet member 140 may be disposed to face the accommodation opening 130 with the plate member 120 interposed therebetween. In other words, the magnet member 140 is disposed outside the accommodation opening 130.
Therefore, the second support unit 200 may be disposed in the accommodation opening 130 to be movable without being disturbed by the magnet member 140.
The magnet member 140 is coupled to the handle member 150. By operating the handle member 150, the magnet member 140 may be controlled to apply or release a magnetic force, that is, an attractive force, to the distribution board 10.
The magnet member 140 may be provided in any form that may be controlled to form or release a magnetic force by being adjusted by the handle member 150. Alternatively, the magnet member 140 may be provided in any form in which the intensity of the magnetic force formed by being adjusted by the handle member 150 may be controlled. In an embodiment, the magnet member 140 may be provided as an electromagnet, a permanent magnet, or the like.
A plurality of magnet members 140 may be provided. The plurality of magnet members 140 may be supported by the plate member 120 at different positions. Each of the plurality of magnet members 140 may be coupled to or separated from the distribution board 10.
In the illustrated embodiment, three magnet members 140 are provided, including a first magnet member 141, a second magnet member 142, and a third magnet member 143.
The first magnet member 141 is biased to the upper side and is coupled to and supported by the first plate member 121. The first magnet member 141 is located adjacent to one end in the extension direction of the first plate member 121, i.e., to the left end in the illustrated embodiment. In the above embodiment, it will be understood that the first magnet member 141 is located adjacent to the upper end of the first column member 111.
The second magnet member 142 is positioned to be biased to the lower side and is coupled to and supported by the second plate member 122. The second magnet member 142 is located adjacent to the other end in the extension direction of the second plate member 122, i.e., to the right end in the illustrated embodiment. In the above embodiment, it will be understood that the second magnet member 142 is located adjacent to the lower end of the second column member 112.
Therefore, it may be said that the first magnet member 141 and the second magnet member 142 are spaced apart from each other in a diagonal direction of the accommodation opening 130 to couple the first support unit 100 and the distribution board 10.
The third magnet member 143 is positioned to be biased to the upper side and is coupled to and supported by the first plate member 121. The third magnet member 143 is located adjacent to the other end in the extension direction of the first plate member 121, i.e., to the right end in the illustrated embodiment. In the above embodiment, it will be understood that the third magnet member 143 is located adjacent to the upper end of the second column member 112.
In this case, the third magnet member 143 may be optionally provided. In the illustrated embodiment, even if only the first magnet member 141 at the upper left side and the second magnet member 142 at the lower right side are provided, the first support unit 100 may be stably coupled to the distribution board 10.
However, in order to improve the coupling reliability by increasing the coupling force, it is preferable to include the third magnet member 143 to couple the first support unit 100 and the distribution board 10 at various positions.
Therefore, although not shown, it will be understood that an additional magnet member (not shown) may be provided on the lower left side of the second plate member 122. The handle member 150 is rotatably coupled to the magnet member 140.
The handle member 150 is configured to be rotatable by an external force. By operating the handle member 150, the magnet member 140 may be controlled to form or release a magnetic force. In another embodiment, the intensity of the magnetic force formed by the magnet member 140 may be controlled to be adjusted by operating the handle member 150.
The handle member 150 is rotatably coupled to the magnet member 140. In this case, it is preferable that the handle member 150 is positioned opposite to the distribution board 10 and is disposed to be exposed toward the outside of the distribution board 10. In the illustrated embodiment, the handle member 150 is positioned to be biased toward the front side and disposed to face the distribution board 10 with the magnet member 140 interposed therebetween.
The handle member 150 may be configured to be rotatable in the clockwise direction or counterclockwise direction.
When the handle member 150 is rotated in one direction of the clockwise direction and the counterclockwise direction, the magnet member 140 may be controlled to form a magnetic force or to increase the intensity of the formed magnetic force. When the handle member 150 is rotated in the other direction of the clockwise direction and the counterclockwise direction, the magnet member 140 may be controlled to release the magnetic force or to decrease the intensity of the formed magnetic force.
The handle member 150 may be provided in any form capable of controlling whether a magnetic force is formed or intensity of the magnet member 140 by being operated by an external force. In the illustrated embodiment, the handle member 150 is provided in the form of a dial that is operated by rotation. Alternatively, the handle member 150 may be provided in the form of a button that is operated by pressing.
A plurality of handle members 150 may be provided. The plurality of handle members 150 may be rotatably coupled to a plurality of magnet members 140, respectively. As the plurality of handle members 150 are operated, a magnetic force formed by the plurality of magnet members 140 may be controlled.
In this case, the plurality of handle members 150 may be rotated independently of each other. Accordingly, a magnetic force formed by the plurality of magnet members 140 to which the plurality of handle members 150 are coupled may also be controlled independently of each other.
In the illustrated embodiment, three handle members 150 are provided, including a first handle member 151, a second handle member 152, and a third handle member 153. The first handle member 151 is rotatably coupled to the first magnet member 141, the second handle member 152 to the second magnet member 142, and the third handle member 153 to the third magnet member 143, respectively.
The gripping member 160 is a portion where the first support unit 100 is gripped by an operator or any equipment.
The operator or any equipment may easily move the first support unit 100 and other components of the draw in and out apparatus 31 coupled to the first support unit 100 by gripping the gripping member 160. The gripping member 160 is positioned to be biased toward the upper side of the first support unit 100.
The gripping member 160 is coupled to the plate member 120. Specifically, the gripping member 160 is coupled to the outside of the first plate member 121 disposed on the upper side, i.e., the upper side in the illustrated embodiment. The gripping member 160 may be disposed at a central portion in the longitudinal direction of the first plate member 121, that is, at a central portion in the left-right direction in the illustrated embodiment.
The first thickness t1 of the first plate member 121 is formed to be greater than or equal to the second thickness t2, so that the coupling state between the gripping member 160 and the first plate member 121 may be stably maintained. In addition, as described above, the above structure allows the first support unit 100 to be moved while the gripping member 160 is gripped without deformation.
The gripping member 160 may have an arbitrary shape that can be gripped by an operator or equipment. In the illustrated embodiment, the gripping member 160 includes a first portion which obliquely extends from the upper surface of the first plate member 121, a second portion which is continuous with the first portion and extends horizontally, and a third portion which is continuous with the second portion and obliquely extends toward the upper surface of the first plate member 121.
The second support unit 200 is movably coupled to the first support unit 100. The second support unit 200 may be moved along the first axis a1 while being coupled to the first support unit 100. Accordingly, a position of the power unit 500 coupled to the second support unit 200 in a direction along the first axis a1, that is, a position in the up-down direction in the illustrated embodiment may be adjusted.
Therefore, it may be said that the second support unit 200 is coupled to the first support unit 100 so as to be elevated.
The second support unit 200 may be detachably coupled to the first support unit 100. The coupling is achieved by the second coupling unit 420.
The second support unit 200 supports other components of the draw in and out apparatus 31. In the illustrated embodiment, the second support unit 200 movably supports the third support unit 300 and the power unit 500.
The second support unit 200 forms a path through which the third support unit 300 and the power unit 500 coupled thereto move along the second axis a2 (see
Therefore, it may be said that the second support unit 200 movably supports the third support unit 300 and the power unit 500 along the second axis a2.
The second support unit 200 is coupled to the coupling unit 400. Various components of the second support unit 200 may be fixedly coupled to each other by the second coupling unit 420. In addition, the second support unit 200 may be movably coupled to the first support unit 100 by the second coupling unit 420. Furthermore, the third support unit 300 and the power unit 500 coupled thereto may be movably coupled to the second support unit 200 by a third coupling unit 430.
In the embodiments shown in
The beam member 210 forms a part of the second support unit 200. The beam member 210 is formed to extend in one direction, that is, in the left-right direction in the illustrated embodiment, to form an outer shape in the height direction of the second support unit 200. As will be described later, the beam member 210 functions as the second axis a2 for movably supporting the third support unit 300 and the power unit 500.
