The present invention relates to a gear ratchet tensioner for indirect live wire work and an uninterruptible power distribution method for indirect live wire work, and more particularly, to an automatic direction switching pendulum-type rotary drive gear ratchet tensioner having an unlimited tension distance adjustment function for indirect live wire work and an uninterruptible power distribution method of performing indirect live wire work using the same, configured to automatically adjust, without a separate rotational direction switching operation, a rotation direction by simply operating a rotary lever using a stick for indirect live wire work so as to pull or release an insulating rope without any limitations on the length of the rope through a gear roller and to prevent reverse rotation, wherein the gear ratchet tensioner is used to safely install or remove a suspension insulator and to perform wiring work on an electric wire in a live wire state without any limitations on the tension distance through the indirect live wire work.
In general, live wire work refers to line work conducted in a state in which power transmission is continuously performed through a line without a power outage on the line. Meanwhile, since the risk of safety incidents is very high during live wire work, live wire work is conducted by a trained worker with strict adherence to specific safety and insulation standards only when it is difficult to cut off power. More specifically, when it is difficult to stop operation of transmission and distribution facilities and the like, live wire work is conducted by a trained worker. Here, the trained worker is required to use insulating protective equipment or protective equipment.
Live wire work on the electric line is divided into direct live wire work and indirect live wire work. Indirect live wire work is a method of conducting live wire work indirectly using an insulating tool such as a stick. Although indirect live wire work is safe, there is a disadvantage of being labor intensive.
In addition, direct live wire work is a method in which a worker wears an insulated glove in an insulated bucket and works in direct contact with an electric wire in a live wire state. While direct live wire work is simple and saves working time, there is a disadvantage in that the worker is exposed to a high risk of electric shock, which often causes serious injury. Live wire work includes inspection, repair, replacement, and cleaning of a wire component such as a suspension insulator. Depending on the types of live wire work, either a direct live wire work method or an indirect live wire work method may be appropriately used.
Meanwhile, utilization of a wire grip is high in various types of live wire work. The wire grip is a device configured to pull or release, during live wire work, a wire in order to obtain an appropriate dip of the wire at the time of performing a dip adjustment process of the wire and wiring work. Here, the wire grip has a drum configured for a belt to be wound therearound or for the belt to be unwound therefrom by forward and reverse rotation of the drum. An appropriate dip of a wire may be obtained through operation of the drum.
However, the conventional tensioner has a problem in that the working distance is limited because the length of a belt wound around a drum is limited to about 1 m.
Therefore, in order to address the above-mentioned problems, the applicant of the present invention has proposed a gear tensioner capable of freely adjusting a length of an insulating rope, thereby making it possible to stretch a wire, connect wires to each other, and adjust tension of a wire without any limitations on the working distance.
However, the conventional gear tensioner as described above is required to perform the operation of a reverse rotation prevention part forming a separate pawl key structure so as to control forward or reverse rotation of a roller. Accordingly, operation of the gear tensioner is significantly inconvenient, and a worker needs to perform operation in close proximity to the wire. In consideration of these circumstances, there is a problem in that a worker is exposed to safety hazards.
In addition, since an insulating rope is configured to simply pass through a roller, a worker needs to adjust tension of the insulating rope by pulling or releasing the insulating rope. Accordingly, a worker has considerable fatigue during tension adjustment of the insulating rope, and there is a limitation on tension adjustment of the insulating rope. Furthermore, the conventional gear tensioner may not be used for indirect live wire work.
Therefore, the present invention has been made in view of the above problems, and it is an object of the present invention to provide an automatic direction switching pendulum-type rotary drive gear ratchet tensioner having an unlimited tension distance adjustment function for indirect live wire work and an uninterruptible power distribution method of performing indirect live wire work using the same, configured to adjust, when an insulating rope is pulled or released by a gear roller of a tensioner without limitation, forward or reverse rotation for pulling or releasing the insulating rope by operating an automatic reversing pawl and a roller shaft operating plate in accordance with reciprocating pendulum motion of a pendulum, thereby enabling forward or reverse rotation of a roller shaft to be automatically performed by operating a rotary lever using a stick for indirect live wire work. In this manner, while the indirect live wire work is conducted on a wire in a state in which power transmission is continuously performed through the wire, a dip of the wire may be appropriately adjusted, the wire may be pulled by the tensioner so as to obtain an appropriate dip of the wire and may be installed on an electric pole, and suspension insulator replacement work may be reliably performed with unlimited tension control, thereby making it possible to stably perform wiring work using the automatic direction switching pendulum-type rotary drive gear ratchet tensioner.
It is another object of the present invention to provide an automatic direction switching pendulum-type rotary drive gear ratchet tensioner having an unlimited tension distance adjustment function for indirect live wire work and an uninterruptible power distribution method of performing indirect live wire work using the same, configured to provide a roller shaft driven by a backstop ratchet ring operated by a multi-angle bundle pawl, thereby making it possible not only to reliably prevent reverse rotation, but also to perform stable rotational driving by preventing backlash occurrence during reverse rotational driving.
In accordance with an aspect of the present invention, the above and other objects can be accomplished by the provision of an automatic direction switching pendulum-type rotary drive gear ratchet tensioner including a body formed of front and rear support plates so as to be formed open to an upper side, a lower side, and one side of the body, wherein an idle gear and an interlocking gear having a support roller are engaged with each other and are axially installed at a front middle part and one side of the front support plate, the body including an insulating rope connection part formed on one end of the body and a hook formed on the other end of the body, upper and lower guide rollers respectively formed on upper and lower portions of the one side of the body, and a lever installation part disposed on a front side of the one side of the body, the lever installation part being configured to restrict the idle gear and the interlocking gear,

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.
As shown in
First, the body 100 is configured to form a basic structure of the automatic direction switching pendulum-type rotary drive gear ratchet tensioner having an unlimited tension distance adjustment function for indirect live wire work 1 according to the present invention. Further, the body 100 is formed of front and rear support plates 110 and 110′ so as to be formed open on the upper side, the lower side, and one side thereof. Here, one end of each of the front and rear support plates 110 and 110′ is inclined and bent in the forward-and-rearward direction so as to guide entry and exit of the insulating rope 1100 to be described later.
In addition, a front middle part of the front support plate 110 is configured to be engaged with a drive gear 423a of an inner ring 420 to be described later, and an idle gear 120 is axially installed in the front middle part.
Additionally, the front support plate 110 has an interlocking gear 130 axially installed on the front side thereof, and one side of the interlocking fear is engaged with the idle gear 120.
In this case, the interlocking gear 130 connects the front and rear support plates 110 and 110′ to each other and is axially installed therebetween. A support roller 131 is formed between the front and rear support plates 110 and 110′. The support roller 131 is made of metal, and processing such as knurling is performed on the outer circumferential surface of the support roller to prevent slippage.
Further, the body 100 includes an insulating rope connection part 140 and a hook 150 respectively disposed at central portions of one end and the other end and configured to be moved upwards and downwards between the front and rear support plates 110 and 110′.
The body 100 includes a pair of upper and lower guide rollers 160 and 160′ respectively installed at the upper side and the lower side thereof and configured to guide movement of the insulating rope 1100 between the front and rear support plates 110 and 110′. When the insulating rope 1100 is pulled or released, these upper and lower guide rollers 160 and 160′ interfere with the insulating rope 1100 and guide stable movement of the insulating rope 1100 through rolling operation thereof.
In addition, the body 100 includes a hollow lever installation part 111 formed on one front side thereof. In this case, the lever installation part 111 is configured to restrict the idle gear 120 and the interlocking gear 130.
In addition, the body 100 is configured to further include an insulating rope pressurization opening/closing means 170 formed to face the support roller 131 and configured to increase the tension limit by applying pressurizing force to the insulating rope 1100.
Here, referring to
In addition, the insulating rope pressurization opening/closing means 170 includes a pressurizing roller 172 formed to face the support roller 131 and configured to apply pressurizing force. The pressurizing roller 172 is made of a silicone material so as to provide elasticity and prevent slippage, and is formed between the front and rear support plates 110 and 110′.
In this case, the pressurizing roller 172 is formed around a pressurizing roller shaft 172a configured for both sides thereof to be accommodated in the guide groove 171. The rear side of the pressurizing roller shaft 172a is formed to protrude toward the rear side of the rear support plate 110′.
In addition, the insulating rope pressurization opening/closing means 170 includes a spring housing 173 configured to provide spring elasticity to the pressurizing roller 172. The spring housing 173 is configured to be connected to a shaft 173a on the rear side of the rear support plate 110′ so as to be rotatable upwards and downwards. The spring housing has a vertical hole 174 formed to pass through the front and rear sides thereof, thereby penetrating the protruding rear of the pressurizing roller shaft 172a.
A pressurizing spring 175 is configured to be elastically installed on the inside of the spring housing 173. Here, the pressurizing spring provides spring force to the pressurizing roller shaft 172a.
A “¬”-shaped housing hook 176 is formed on the other end of the spring housing 173.
Additionally, the insulating rope pressurization opening/closing means 170 includes a pressurization release part 180 formed to be hooked by the spring housing 173 and configured to fix the spring housing 173 and maintain pressurizing force of the pressurizing roller 172.
Here, the pressurization release part 180 is formed on the rear support plate 110′ in a state of facing the spring housing 173. The pressurizing release part is formed to be open toward the spring housing 173. Further, the pressurizing release part has a lever housing 181 formed on the circumference thereof. Here, the lever housing has a horizontal long hole 182 formed therein and configured to communicate with the inside of the spring housing 173.
The lever housing 181 includes a release lever 183 formed to penetrate the horizontal long hole 182 and configured to be accommodated in the horizontal long hole or protrude outwards therefrom. The release lever 183 includes an “L”-shaped lever hook 184 formed to protrude so as to be hooked on the housing hook 176.
A spring 185 is configured to be elastically installed on the inside of the lever housing 181 such that the release lever 183 has protruding force toward the spring housing 173.
Accordingly, the spring housing 173 of the insulating rope pressurization opening/closing means 170 is rotated around the shaft 173a so as to allow the housing hook 176 to be fixedly hooked on the lever hook 184 in a state of being accommodated in the guide groove 171. In this case, the insulating rope 1100 applies pressurizing force between the support roller 131 and the pressurizing roller 172.
Conversely, when the spring housing 173 is pressed such that the pressurizing spring 175 is compressed, the release lever 183 of the pressurization release part 180 is pulled. In this case, locking force of the housing hook 176 and the lever hook 184 is released, and the spring housing 173 is rotated to be separated from the guide groove 171. Here, pressurizing force of the insulating rope 1100 is released, and the insulating rope 1100 becomes movable, thereby allowing the insulating rope to be mounted or removed from the body 100 of the insulating rope 1100.
In the configuration of the automatic direction switching pendulum-type rotary drive gear ratchet tensioner having an unlimited tension distance adjustment function for indirect live wire work 1 according to the present invention, the rotary operating lever 200 is configured to provide operating force for forward rotation of a roller shaft 310 to be described later or reverse rotation thereof.

In addition, the rotary operating lever 200 includes a cam 220 provided at a tip portion of the rotary operating shaft 210 and disposed at a location eccentric from a central portion of the tip portion to one side.
In addition, the rotary operating lever 200 includes a rotary operating mechanism 230 provided around the rotary operating shaft 210 and disposed on the rear side of the cam 220. The rotary operating mechanism 230 is configured to be slidably coupled to the rotary operating shaft 210.
In addition, a movable long hole 231 is formed on one side of the circumference of the rotary operating mechanism 230 so as to form an angle of about 110° in the circumferential direction, and a locking protrusion 232 is formed to protrude around the other side of the circumference of the rotary operating mechanism 230.
In addition, the rotary operating lever 200 includes a buffer key 240 configured to provide connecting force between the rotary operating shaft 210 and the rotary operating mechanism 230. In this case, one side of the buffer key 240 is configured to be fixed to the rotary operating shaft 210 and the other side thereof is configured to be located on the inner side of the movable long hole 231 of the rotary operating mechanism 230.
Here, when the rotary operating shaft 210 is rotated in the forward direction or reverse direction, the buffer key 240 idles for a predetermined time within the movable long hole 231. When the buffer key 240 is caught at one end of the movable long hole 231, the buffer key 240 is configured to rotate the rotary operating mechanism 230. In this operation process, it is possible to prevent shock overload on the roller shaft operating plate 500 to be described later. Here, the shock overload is caused by sudden rotation.
In the configuration of the automatic direction switching pendulum-type rotary drive gear ratchet tensioner having an unlimited tension distance adjustment function for indirect live wire work 1 according to the present invention, the gear roller 300 is substantially configured to provide forward or reverse rotational force so as to pull or release the insulating rope 1100 to be described later.
To this end, the gear roller 300 has the roller shaft 310 disposed between the front and rear support plates 110 and 110′ and formed to be axially installed on the other side of the body 100. Here, the roller shaft 310 is formed to protrude from the front side of the body 100.
In this case, the gear roller 300 has an insulating rope guide groove 320 on the outer circumference thereof. In this manner, the insulating rope 1100 is accommodated in the insulating rope guide groove.
In the opposite inner surfaces of the insulating rope guide groove 320, a pair of insulating rope pressurization protrusions 330 and 330′ is formed to protrude, and a plurality of the pair of insulating rope pressurization protrusions are arranged radially in a spiral shape. In this case, the insulating rope pressurization protrusions 330 and 330′ are configured to face each other and protrude to intersect each other such that the insulating rope 1100 is inserted therebetween to apply pressure to the insulating rope.
In the configuration of the automatic direction switching pendulum-type rotary drive gear ratchet tensioner having an unlimited tension distance adjustment function for indirect live wire work 1 according to the present invention, the clutch part 400 is configured to implement forward rotation of the roller shaft 310 or reverse rotation thereof. The roller shaft 310 is configured to penetrate the body 100 and protrude from the front side of the body so as to be coupled to the clutch part 400.
Meanwhile, in the present invention, the configuration of the clutch part 400 is not limited. For example, the clutch part may be configured as a cam clutch in which a cam is formed between an inner ring and an outer ring, only the inner ring is rotatable when the inner ring is rotated in the forward direction, and the inner ring and the outer ring are simultaneously rotatable when the inner ring is rotated in the reverse direction.
In addition, the clutch part 400 may be configured as a backstop ratchet ring 401 with reference to
First, in the configuration of the backstop ratchet ring 401, the outer ring 410 is configured to output power to the outside. The outer ring 410 has an inner ring mounting hole 411 disposed at a central portion thereof and configured to allow the inner ring 420 to be described later to be mounted therein. Here, the inner ring mounting hole 411 is formed to have a circular shape in a state of penetrating the outer ring 410.
In this case, in the present invention, the outer ring 410 is configured to have outer ring saw teeth 412 formed on the inner peripheral surface of the inner ring mounting hole 411, and the outer ring saw teeth 412 are configured to have straight portions and inclined portions that are continuously formed.
Meanwhile, in the present invention, each of the straight portions forming the outer ring saw teeth 412 is configured to be caught during power transmission, and each of the inclined portions forming the outer ring saw teeth 412 is configured to guide slippage during idling operation.
In addition, in the present invention, the outer ring 410 may further include a plurality of stopping grooves 413 formed in the outer circumference thereof at regular intervals and configured to allow the rotation control lever 440 to be respectively caught therein or released therefrom.
In the configuration of the backstop ratchet ring 401, the inner ring 420 is configured to substantially transmit main power. Further, the inner ring 420 interferes with the outer ring 410 so as to transmit main power to the outer ring 410 or is released from the outer ring 410 so as to release the main power from the outer ring 410.
To this end, in the present invention, the inner ring 420 is configured to have a circular ring shape. Here, the inner ring 420 has a roller shaft mounting hole 421 formed to pass through a central portion thereof and configured to allow the roller shaft 310 provided to transmit rotational force to be coupled thereto. Further, the inner ring 420 is configured to be mounted in the inner ring mounting hole 411 of the outer ring 410.
In addition, the inner ring 420 has a plurality of bundle pawl mounting grooves 422 formed in the outer circumference thereof at regular intervals in the circumferential direction and configured to enable first, second, and third multi-angle bundle pawls 431, 432, and 433 to be described later to be respectively mounted therein.
Meanwhile, in the present invention, the outer ring 410 and the inner ring 420 are configured to enable close coupling therebetween. Further, sliding operation may be stably performed when the outer ring 410 and the inner ring 420 are coupled to each other.
To this end, first, each of the outer ring saw teeth 412 of the outer ring 410 is configured to protrude toward the inside of the inner ring mounting hole 411 by a predetermined amount. Accordingly, front and rear stepped portions 412a and 412b are respectively formed on the front side and the rear side of the outer ring saw teeth 412.
In addition, the inner ring 420 is configured to have a seating protrusion 423 formed to protrude from the rear circumference thereof and slidably seated on the rear stepped portion 412b of the outer ring 410. Further, the inner ring 420 is configured to have a finishing plate support portion 424 formed to protrude from the front side thereof so as to extend from the roller shaft mounting hole 421.
In this case, the drive gear 423a is formed on the rear circumference of the seating protrusion 423 of the inner ring 420. The drive gear 423a is configured to be engaged with the idle gear 120 installed on the body 100 so as to provide rotational force in the same direction as the interlocking gear 130 through the idle gear 120.
Further, the front side of the inner ring 420 is configured to be finished with a finishing plate 425. Here, the circumference of the finishing plate 425 is configured to be seated on the front stepped portion 412a of the outer ring 410 and to be bolted to the inner ring 420, thereby constraining the outer ring saw teeth 412. Further, the finishing plate 425 is configured to have a through hole 425a formed in a central portion thereof and configured to allow the finishing plate support portion 424 of the inner ring 420 to pass therethrough.
In the configuration of the backstop ratchet ring 401, the multi-angle bundle pawl unit 430 serves as a means to transmit power of the inner ring 420 to the outer ring 410 or release power of the inner ring 420 from the outer ring 410 in response to the outer ring saw teeth 412 of the outer ring 410. In the present invention, the multi-angle bundle pawl unit 430 is formed of a plurality of groups including the first, second, and third multi-angle bundle pawls 431, 432, and 433.
To this end, the first, second, and third multi-angle bundle pawls 431, 432, and 433 respectively have springs S each installed in a corresponding one of the bundle pawl mounting grooves 422, thereby allowing the first, second, and third multi-angle bundle pawls 431, 432, and 433 to protrude from the outer circumference of the inner ring 420. Further, the first, second, and third multi-angle bundle pawls 431, 432, and 433 are configured to be engaged with the outer ring saw teeth 412 of the outer ring 410, thereby providing rotational force in one direction.
In this case, in the present invention, the first, second, and third multi-angle bundle pawls 431, 432, and 433 are configured to form three groups. Here, each of the three groups may be formed of a corresponding one of first, second, and third engagement tools 431a, 432a, and 433a, in which each of the radially arranged (that is, arranged at 90° intervals) four first engagement tools 431a, four second engagement tools 432a, and four third engagement tools 433a forms one group.
In the present invention, the first, second, and third engaging tools 431a, 432a, and 433a corresponding to respective groups are configured to have protruding force by respectively inserting the springs S into the bundle pawl mounting grooves 422. The first, second, and third engaging tools 431a, 432a, and 433a have engagement tool saw teeth 431b, 432b, and 433b respectively provided on the tip portions thereof, in which each of the engagement tool saw teeth 431b, 432b, and 433b is formed to have a straight portion and an inclined portion so as to be engaged with the outer ring saw teeth 412 of the outer ring 410.
Particularly, in the present invention, when the first, second, and third engagement tools 431a, 432a, and 432a respectively corresponding to the first, second, and third multi-angle bundle pawls 431, 432, and 433 of the respective groups are respectively mounted in the bundle pawl mounting grooves 422, the first, second, and third engagement tools 431a, 432a, and 433a are respectively disposed at positions where the first, second, and third engagement tools 431a, 432a, and 433a intersect each other. That is, the first engagement tool 431a of the first multi-angle bundle pawl 431, the second engagement tool 432a of the second multi-angle bundle pawl 432, and the third engagement tool 433a of the third multi-angle bundle pawl 433 are continuously and repeatedly formed in one rotational direction. In this manner, the engagement tool saw teeth 431b, 432b, and 433b are configured to be engaged with the outer ring saw teeth 412 at sequential positions respectively having different angles.
That is, in the present invention, any one of the first, second, and third engagement tool saw teeth 431b, 432b, and 433b of the first, second, and third engagement tool 431a, 432a, and 433a of the first, second, and third multi-angle bundle pawls 431, 432, and 433 is engaged with the outer ring saw teeth 412 of the outer ring 410. For example, when the straight portions of the engagement tool saw teeth 431b of the first engagement tool 431a are respectively in contact with the straight portions of the outer ring saw teeth 412, the straight portions of the engagement tool saw teeth 432b of the second engagement tool 432a are respectively located at the ends of the inclined portions of the outer ring saw teeth 412. As a result, the engagement tool saw teeth 432b are not engaged with the outer ring saw teeth 412. In addition, the straight portions of the engagement tool saw teeth 433b of the third engagement tool 433a are respectively located at the middle portions of the inclined portions of the outer ring saw teeth 412. In this manner, segmented engagement sections of the engagement tool saw teeth 431b, 432b, and 433b are provided within one pitch of the outer ring saw teeth 412, thereby maximally reducing a gap between the saw teeth.
Meanwhile, in the embodiment of the present invention, the first, second, and third multi-angle bundle pawls 431, 432, and 433 forming a plurality of groups have been described as three groups, but the present invention is not limited thereto. The first, second, and third multi-angle bundle pawls 431, 432, and 433 may be arranged in various configurations with equal intervals therebetween.
For example, the plurality of groups may be formed of four groups of multi-angle bundle pawls, and each of the four groups may be formed of four engagement tools. Alternatively, the plurality of groups may be formed of three groups of multi-angle bundle pawls, and each of the three groups may be formed of eight engagement tools. As described above, the number of groups and the number of engagement tools are adjusted, thereby making it possible to control a degree of precision depending on the purpose of use of the backstop ratchet ring 401.
In the configuration of the backstop ratchet ring 401, the rotation control lever 440 is configured to control rotation and stoppage of the outer ring 410.
To this end, the rotation control lever 440 is configured to be axially installed in the body 100 and to have a spring installed in the body 100. In this manner, the rotation control lever 440 is configured to be inserted into and removed from the stopping groove 413 of the outer ring 410 through rotational operation thereof. When the rotation control lever 440 is inserted thereinto, rotation of the outer ring 410 is blocked, and when the rotation control lever 440 is removed therefrom, rotation of the outer ring 410 is possible.

Further, the pendulum 600 protrudes from one side thereof and has a horizontal long hole 610 formed therein and configured to accommodate the cam 220 of the rotary operating lever 200. When the cam 220 is rotated, the cam 220 interferes with the horizontal long hole 610 so as to perform pendulum motion in which the pendulum 600 reciprocates relative to the roller shaft 310.
In addition, the pendulum 600 has an automatic reversing pawl mounting groove 620 formed therein and configured to allow the automatic reversing pawl 800 to be described later to be mounted on the front surface between the rotary operating shaft 210 and the roller shaft operating plate 500.

To this end, the automatic reversing pawl 800 is configured to be coupled to the automatic reversing pawl mounting groove 620 of the pendulum 600 with a pawl shaft 801, thereby enabling the roller shaft operating plate 500 to perform reciprocating pendulum motion.
Meanwhile, in the present invention, referring to
Further, the automatic reversing pawl 800 includes first locking grooves 821 and 821′ and second locking grooves 822 and 822′ each formed to have a curved curvature and disposed around the automatic reversing pawl 800. In this case, the first locking grooves 821821′ and the second locking grooves 822 and 822′ are configured to be symmetrical to each other so that the first locking groove 821 and the second locking groove 822 are respectively located on the first and second locking protrusions 810 and 810′.
Additionally, the automatic reversing pawl 800 has a reversing key mounting groove 830 formed at a central portion thereof and configured to allow the pawl revering key 900 to be described later to be mounted therein. The reversing key mounting groove 830 is configured to have a tapered groove shape extending from the roller shaft operating plate 500 side to the rotary operating shaft 210 side.
Meanwhile, the automatic reversing pawl 800 is configured to be installed through first and second reversing pawl spring balls 840 and 840′. The first and second reversing pawl spring balls 840 and 840′ are configured to be coupled to the pendulum 600 so as to have elasticity allowing the first and second reversing pawl spring balls 840 and 840′ to protrude toward the automatic reversing pawl 800.
In this case, in the present invention, the first and second reversing pawl spring balls 840 and 840′ are configured to interfere with the first locking grooves 821 and 821′ and the second locking grooves 822 and 822′. Here, the first reversing pawl spring ball 840 is configured to interfere with any corresponding one of the first locking grooves 821 and 821′ at a location at which the first reversing pawl spring ball 840 and the corresponding one intersect each other, and the second reversing pawl spring ball 840′ is configured to interfere with any corresponding one of the second locking grooves 822 and 822′ at a location at which the second reversing pawl spring ball 840′ and the corresponding one intersect each other.
For example, when the roller shaft operating plate 500 is rotated in the forward direction, that is, rotated clockwise, the first revering pawl spring ball 840 located on one side of the pendulum 600 is desirably caught in the first locking groove 821′ located on one side of the automatic reversing pawl 800, and the first reverse pawl spring ball 840′ located on the other side of the pendulum 600 is desirably caught in the second locking groove 822 located on the other side of the automatic reversing pawl 800. Conversely, when the roller shaft operating plate 500 is rotated counterclockwise, the first revering pawl spring ball 840 located on one side of the pendulum 600 is desirably caught in the first locking groove 821 located on one side of the automatic reversing pawl 800, and the first reverse pawl spring ball 840′ located on the other side of the pendulum 600 is desirably caught in the second locking groove 822′ located on the other side of the automatic reversing pawl 800.

To this end, the pawl reversing key 900 is accommodated in the reversing key mounting groove 830 of the automatic reversing paw1800. Further, the pawl reversing key 900 is coupled to the roller shaft support plate 700 with the same pawl shaft 801 as the automatic reversing pawl 800 and protrudes from one side thereof, that is, protrudes toward the rotary operating shaft 210. In the process of rotating the rotary operating shaft 210, the pawl reversing key 900 is configured to interfere with the locking protrusion 232 of the rotary operating mechanism 230, thereby performing reciprocating pendulum motion.
In this case, the pawl reversing key 900 is configured to have horizontal force so as to constantly maintain horizontality thereof. To this end, opposite sides of the pawl reversing key 900 are configured to be elastically installed by first and second reversing key spring balls 910 and 910′ respectively formed on opposite sides of the roller shaft support plate 700 relative to the pawl shaft 801.
In the configuration of the automatic direction switching pendulum-type rotary drive gear ratchet tensioner having an unlimited tension distance adjustment function for indirect live wire work 1 according to the present invention, the roller shaft rotary lever 1000 is configured to transmit rotational force of the roller shaft operating plate 500 to the roller shaft 310.
To this end, the roller shaft rotary lever 1000 is configured to be coupled to the front side of the roller shaft 310 and the roller shaft operating plate 500. Further, the roller shaft rotary lever is configured to be rotated in conjunction with the roller shaft 310 and the roller shaft operating plate 500.
In the configuration of the automatic direction switching pendulum-type rotary drive gear ratchet tensioner having an unlimited tension distance adjustment function for indirect live wire work 1 according to the present invention, the insulating rope 1100 is configured to be wound through the open side of the body 100 and unwound through the insulating rope guide groove 320 of the gear roller 300. Here, the insulating rope may be wound or unwound through the insulating rope guide groove during forward rotation of the gear roller 300 or reverse rotation thereof.
Here, the insulating rope 1100 passing through the gear roller 300 is configured such that the insulating rope is pulled or released by a worker through the lower portion of the gear roller in the drawing, and the insulating rope on the upper portion of the gear roller in the drawing is fixed to the insulating rope connection part 140 and forms a tension direction of the insulating rope connected to the wire through a wire clip 1200 to be described later. The insulating rope 1100 passing through the gear roller is primarily pressurized by the pressurization protrusions 330 and 330′ of the gear roller 300. Then, the insulating rope is secondarily pressurized by the insulating rope pressurization opening/closing means 170, thereby increasing the tension limit when tension is applied to the insulating rope.
In the configuration of the automatic direction switching pendulum-type rotary drive gear ratchet tensioner having an unlimited tension distance adjustment function for indirect live wire work 1 according to the present invention, the wire clip 1200 is configured to be connected to the insulating rope connection part 140 in the tension direction of the insulating rope 1100 released from the body 100 and enables the wire to be gripped and fixed thereto during normal wiring work.
In this case, the wire clip 1200 in the present invention may not be newly implemented. For example, a normal clamp capable of gripping a wire may be applied to the wire clip.
In particular, the wire clip 1200 in the present invention may use a wire clip applied to an automatic direction switching pendulum-type rotary drive ratchet wire grip for indirect live wire work capable of gripping a wire during indirect live line work, which was invented by the applicant of the present invention and disclosed in Korean Patent No. 10-2161405.
Hereinafter, the operation of the automatic direction switching pendulum-type rotary drive gear ratchet tensioner having an unlimited tension distance adjustment function for indirect live wire work according to the present invention having the above configuration will be described in detail with reference to the attached drawings.
With reference to
Here, in the automatic direction switching pendulum-type rotary drive gear ratchet tensioner having an unlimited tension distance adjustment function for indirect live wire work 1 according to the present invention, first, in order to pull the wire and the insulating rope 1100 using the gear ratchet tensioner, the roller shaft 310 is rotatably driven clockwise, that is, in the forward direction. Hereinafter, the above-described operating state will be described.
To this end, referring to
Accordingly, when the rotary operating lever 200 is operated to rotate the rotary operating shaft 210 counterclockwise, the cam 220 is rotated within the horizontal long hole 610 of the pendulum 600. In this process, the pendulum 600 is subjected to reciprocating pendulum motion relative to the roller shaft 310.
Simultaneously, the locking protrusion 232 of the rotary operating mechanism 230 formed on the rotary operating shaft 210 turns the pawl reversing key 900 toward the first locking grooves 821 and 821′. Accordingly, the pawl reversing key 900 pushes the automatic revering pawl 800 in the direction of the first locking grooves 821 and 821′ and rotates the same clockwise around the pawl shaft 801. In this case, the first locking protrusion 810 on the first locking groove 821 side is engaged with the saw teeth 510 of the roller shaft operating plate 500.
Accordingly, when the rotary operating shaft 210 is continuously rotated, the pendulum 600 performs reciprocating pendulum motion by operation of the cam 220 and the horizontal long hole 610. In this process, the pawl reversing key 900 rotated in the rotation direction due to interference with the locking protrusion 232 of the rotary operating mechanism 230 supports the first locking grooves 821 and 821′ side of the automatic reversing pawl 800 and rotatably pushes the roller shaft operating plate 500 that is engaged with the automatic reversing pawl 800 and performs reciprocating pendulum motion with the pendulum 600. In this case, the roller shaft 310 is rotated in conjunction with forward rotation of the roller shaft operating plate 500, thereby rotating the gear roller 300 and pulling the pressurized insulating rope.
Meanwhile, in the present invention, as described above, reverse rotation of the roller shaft 310 is prevented when rotation of the roller shaft 310 is performed to obtain tension, which is made possible by the clutch part 400.
Here, in the present invention, the clutch part 400 is formed of the backstop ratchet ring 401. Reverse rotation is prevented by the backstop ratchet ring 401, and an operation process of the backstop ratchet ring 401 will be described below.
Referring to
That is, since the springs S are respectively installed in the first, second, and third engagement tools 431a, 432a, and 433a of the inner ring 420, the engagement tool saw teeth 431b, 432b, and 433b that pass over the outer ring saw teeth 412 are pushed rearwards by compressive force of the springs S, and simultaneously, the inclined portions of the outer ring saw teeth 412 and the inclined portions of the engagement tool saw teeth 431b, 432b, and 433b slide and move over each other.
Meanwhile, in a state in which the forward drive as described above is stopped, rotational force causing the inner ring 420 to be rotated in the reverse direction may be generated by tension of the insulating rope 1100. In this case, in the backstop ratchet ring 401, any one of the engagement tool saw teeth 431b, 432b, and 433b respectively formed on the first, second, and third engagement tools 431a, 432a, and 433a of the first, second, and third multi-angle bundle pawls 431, 432, and 433 is engaged with the outer ring saw teeth 412, thereby preventing reverse rotation of the inner ring 420. Accordingly, it is possible to stably wind the insulating rope 1100 and to reliably apply tension to the insulating rope 1100.
In particular, in the present invention, as described above, in the process of rotating the inner ring 420, the drive gear 423a formed on the inner ring 420 is configured to be engaged with the idle gear 120 of the body 100. Here, rotational force is transmitted to the idle gear 120. Then, rotational force is transmitted from the idle gear to the interlocking gear 130. In this process, rotational force of the interlocking gear 130 and rotational force of the drive gear 423a are applied in the same direction.
In this case, the interlocking gear 130 has the support roller 131 formed thereon. When the support roller 131 is rotated, the gear roller 300 is rotated by pressurization from the pressurizing roller 172. Accordingly, the insulating rope 1100 is pulled by rotation of the gear roller 300, thereby increasing the tension limit.
Conversely, when the insulating rope 1100 is unwound from the gear roller 300 so as to release tension of the insulating rope 1100, the roller shaft 310 is rotated counterclockwise, that is, in the reverse direction. The above-described operating state of the roller shaft 310 will be described below.
Referring to
In this case, the locking protrusion 232 of the rotary operating mechanism 230 formed on the rotary operating shaft 210 rotatably pushes the pawl reversing key 900 toward the second locking grooves 822 and 822′. Accordingly, the pawl reversing key 900 pushes the automatic reversing pawl 800 in the direction of the second locking grooves 822 and 822′ so as to rotate the automatic reversing pawl 800 counterclockwise around the pawl shaft 801. At this time, the second locking protrusion 810′ on the second locking groove 822 side of the automatic reversing pawl 800 is engaged with the saw teeth 510 of the roller shaft operating plate 500.
Accordingly, when the rotary operating shaft 210 is continuously rotated, the pendulum 600 performs reciprocating pendulum motion by operation of the cam 220 and the horizontal long hole 610. In this process, the pawl reversing key 900 rotated in the rotation direction due to interference with the locking protrusion 232 of the rotary operating mechanism 230 supports the second locking groove 822′ side of the automatic reversing pawl 800 and rotatably pushes the roller shaft operating plate 500 that is engaged with the automatic reversing pawl 800 and performs reciprocating pendulum motion with the pendulum 600. In this case, the roller shaft 310 is rotated in conjunction with reverse rotation of the roller shaft operating plate 500, thereby unwinding the insulating rope 1100 from the gear roller.
Meanwhile, in the present invention, as described above, when the outer ring 410 is driven by the reverse operation of the inner ring 420, backlash (backward movement) of the inner ring 420 is maximally reduced so that the possibility of backlash is close to zero, thereby making it possible to prevent impact during power transmission.
The above-described operation may be performed by the multi-angle bundle pawl unit 430 configured to transmit rotational force of the inner ring 420 to the outer ring 410.
That is, with reference to
For example, when the straight portions of the engagement tool saw teeth 431b of the first engagement tool 431a are respectively in contact with the straight portions of the outer ring saw teeth 412 so as to enter the engagement state therebetween, the straight portions of the engagement tool saw teeth 432b of the second engagement tool 432a are respectively located at the ends of the inclined portions of the outer ring saw teeth 412. In this manner, the engagement tool saw teeth 432b are not engaged with the outer ring saw teeth 412. In addition, the straight portions of the engagement tool saw teeth 433b of the third engagement tool 433a are respectively located at the middle portions of the inclined portions of the outer ring saw teeth 412. Accordingly, when the inner ring 420 is rotated, the first, second, and third engagement tools 431a, 432a, and 433a sequentially apply engagement force to the outer ring saw teeth 412. As a result, the multi-angle bundle pawl unit 430 is constantly engaged with the outer ring saw teeth 412 in a sequential manner.
That is, in the backstop ratchet ring 401, segmented engagement sections of the engagement tool saw teeth 431b, 432b, and 433b are provided within one pitch of the outer ring saw teeth 412. Accordingly, even if slight rotation occurs, engagement force is achieved at sequential positions respectively having different angles in a sequential manner. As a result, when reverse power is transmitted, precise power transmission may be performed without backlash occurrence.
Particularly, in the present invention, as described above, in the process of rotating the inner ring 420, the drive gear 423a formed on the inner ring 420 is configured to be engaged with the idle gear 120 of the body 100. In this case, rotational force is transmitted to the idle gear 120. Then, rotational force is transmitted from the ideal gear to the interlocking gear 130. In this process, the interlocking gear 130 has the same direction rotational force as that of the drive gear 423a.
In this case, the interlocking gear 130 has the support roller 131 formed thereon. When the support roller 131 is rotated, the gear roller 300 is rotated by pressurization from the pressurizing roller 172. Accordingly, the insulating rope 1100 is released by rotation of the gear roller, thereby preventing rapid release of the insulating rope 1100.
That is, referring to
Meanwhile, referring to
Hereinafter, an uninterruptible power distribution method of performing indirect live wire work, using the automatic direction switching pendulum-type rotary drive gear ratchet tensioner having an unlimited tension distance adjustment function for indirect live wire work according to the present invention having the above-described configuration will be described in detail with reference to the attached drawings.
Referring to
Hereinafter, the embodiments will be described.
Referring to
First, referring to
Afterwards, the automatic direction switching pendulum-type rotary drive gear ratchet tensioner having an unlimited tension distance adjustment function for indirect live wire work 1 according to the present invention is installed on the wire.
The hook 150 of the gear ratchet tensioner 1 is fixed to an arm-shaped support member at the inner position of each of the start electric pole 10 and the end electric pole 10 within a work section. Thereafter, on a wire located within electric poles and located in a region in which wiring work is safely performed in the state in which power transmission is not performed through the wire, the wire clip 1200 is used to grab a wire to be removed 11 and is installed thereon.
Thereafter, referring to
First, each of the bypass jumper means 30 has one end connected to a corresponding one of both ends of the wire to be removed 11 located inside the work section.
Each of the bypass jumper means 30 has the other end connected to a corresponding one of the old wires 12 located outside the work section in which the start and end electric poles 10 are installed, and the wire to be removed 11 and the old wire 12 are connected to each other through the bypass jumper means.
Afterwards, referring to
First, jumper wires 20 configured to respectively connect the wires to be removed 11 to the old wires 12 are sequentially separated from the start and end electric poles 10 of the work section.
Then, the wire to be removed 11 is separated. Here, both ends of the wire to be removed 11 located between the electric poles within the work section are respectively separated from suspension insulators (not shown in the drawing) respectively installed on the electric poles 10, thereby securing a safe space for wiring work in the state in which power transmission is not performed through the wire. Here, stretching the new wire 13 and pulling the new wire 13 to obtain an appropriate dip thereof are performed in the safe space for wiring work.
Thereafter, referring to
The new wire 13 of the new electric pole 10′ is stretched. Then, the stretched new wire 13 is connected to the suspension insulator from which the wire to be removed 11 is separated. Then, the new wire is pulled to obtain an appropriate dip thereof.
After this work, referring to
Here, the new wires 13 connected to the start and end electric poles 10 located within the work section are respectively connected to the old wires 12 located outside the work section through the bypass jumper means in a sequential manner using the respective new jumper wires 21, and the already installed bypass jumper means 30 is separated from the wire so as to allow the wire to be removed 11 to enter the state in which power transmission is not performed through the wire to be removed.
Afterwards, referring to
Then, while the insulating rope 1100 of the gear ratchet tensioner 1 is released, the wire to be removed 11 in the tensioned state is lowered to the ground and removed. Next, the electric poles 10 in the work section are sequentially removed, thereby completing wiring work for the new wire 13 in the state in which power transmission is performed through the wire.
Meanwhile, in the present invention, when the wire to be removed 11 located between the electric poles is separated, the new wire 13 is installed, and the wire to be removed 11 is removed by using the automatic direction switching pendulum-type rotary drive gear ratchet tensioner having an unlimited tension distance adjustment function for indirect live wire work 1 that holds the wire to be removed 11 and the new wire 13, the rotary operating lever 200 is operated in the forward or reverse direction so as to cause the pendulum 600 to perform reciprocating pendulum motion. Accordingly, it is possible to adjust tension of the insulating rope by rotating the automatic reversing pawl 800 and rotating the roller shaft 310 connected to the roller shaft operating plate 500 in the forward or reverse direction so as to pull or release the insulating rope 1100. In order to adjust tension of the wire to be removed 11 and the new wire 13, tension adjustment may be performed by stopping or rotating the outer ring 410 through attachment and detachment operation of the rotation control lever 440.
That is, in order to rotate the gear roller 300 and pull the insulating rope 1100 so as to apply tension to the wire, the rotation control lever 440 needs to be operated in a state of being fitted into the stopping groove 413 of the outer ring 410.
Thereafter, a stick for live wire work is used to rotate the rotary operating lever 200 counterclockwise in a state in which a safe distance is secured between the worker and the wire. Accordingly, the roller shaft 310 pulls the insulating rope 1100 through clockwise rotation thereof, thereby applying tension to the wire to be removed 11 and the new wire 13.
Meanwhile, in the present invention, as described above, referring to
Thereafter, conversely, in order to release tension of the wire to be removed and the new wire, it is required to rotate the rotary operating lever 200 clockwise using the stick for live wire work in a state in which a safe distance is secured between the wire and the worker. Here, the roller shaft 310 releases the insulating rope 1100 through counterclockwise rotation thereof, thereby releasing tension of the wire to be removed 11 and the new wire 13.
Meanwhile, in the present invention, as described above, referring to
That is, when separation of the wire to be removed 11 located between the electric poles, installation of the new wire 13, and removal of the wire to be removed 11 are performed using the automatic direction switching pendulum-type rotary drive gear ratchet tensioner having an unlimited tension distance adjustment function for indirect live wire work 1 according to the present invention, as described above, forward or reverse rotation of the roller shaft 310 is performed by adjusting forward or reverse direction of the rotary operating lever 200. Accordingly, the insulating rope 1100 may be pulled or released through rotation of the gear roller 300, thereby making it possible to adjust tension of the wire to be removed 11 and the new wire 13.
Meanwhile, in the present invention, when the above-described series of processes is performed, the processes may be sequentially and repeatedly performed for each of the three-phase wires.
Meanwhile, in the first to fifth embodiments of the present invention, each process is described on the basis of a single phase, but in the case of three-phase wires, the same process may be repeatedly performed for each of the three-phase wires.

Then, the wire to be removed 11a is separated. Here, both ends of the wire to be removed 11a located between the electric poles within the work section are respectively separated from suspension insulators (not shown in the drawing) respectively installed on the electric poles for branch wires 10a, thereby securing a safe space for wiring work in the state in which power transmission is not performed through the wire.

The present invention provides an automatic direction switching pendulum-type rotary drive gear ratchet tensioner having an unlimited tension distance adjustment function for indirect live wire work and an uninterruptible power distribution method of performing indirect live wire work using the same, configured to automatically pull or release an insulating rope through forward rotation or reverse rotation of a roller shaft by simply conducting the indirect live wire work without performing a separate rotation direction switching operation. Accordingly, while the indirect live wire work is conducted from a long distance on a wire in a state in which power transmission is continuously performed through the wire, a dip of the wire may be appropriately adjusted, the wire may be pulled to obtain an appropriate dip of the wire and may be fixedly installed on an electric pole, the wire may be removed from the electric pole, and suspension insulator replacement work may be reliably performed with unlimited tension control, thereby making it possible to stably perform wiring work. Additionally, a backstop ratchet ring is capable of preventing reverse rotation of the roller shaft, preventing backlash occurrence when the roller shaft is driven in the reverse direction, and constantly performing bidirectional rotation in a reliable manner, thereby having an effect of securing stability and durability of the device.
