In a pivot-type suspended monorail multi-way turnout system, in order to ensure the smooth deflection of the turnout, a certain gap is often left at the place where the turnout beam and the branch rail beam are docked to avoid obstruction and scratching. In the related technology, bridging structures are often disposed to reduce the impact of gaps on rail traffic. Such bridging structures usually are used for specific gaps under single-way working conditions, that is, they are embedded into gaps with shapes and specifications fitted with them. However, a multi-way turnout has gaps with various gap shapes and specifications, and therefore, the needs of multi-way turnout working conditions cannot be met by such bridging structures, resulting in unreliable jointing effects.

Referring to
In some embodiments, the traveling rail jointing device of the pivot-type suspended monorail multi-way turnout beam may include a jointing plate 10, a rotating support seat 20, a lever 30 and a push-pull assembly 40. A deflecting of a jointing plate 10 is implemented by corporations of the jointing plate 10, a rotating support seat 20, a lever 30 and a push-pull assembly 40. Therefore, the jointing plate 10 can realize a jointing by covering gaps, and in turn, the traveling rail jointing device has a wide range of adaptability to gaps of different shapes and specifications, and can perform reliable and stable jointing.
In some embodiments, the jointing plate 10 is disposed with a rotation shaft 12 thereon along an extension direction of a plate surface thereof. The rotation shaft 12 is rotatably embedded on the rotating support seat 20, and thus the jointing plate 10 can rotate relative to the rotating support seat 20.
A first end of the lever 30 is fixed on the jointing plate 10, and a second end of the lever 30 is connected to the push-pull assembly 40, so that the push-pull assembly 40 can push the jointing plate 10 to deflect so as to cover gaps or stand up. Therefore, a wide range of reliable and efficient jointing operations for various gaps can be achieved by a simple deflection operation of the jointing plate 10. The jointing device has a relatively simple structure and good on-site mounting adaptability.
The push-pull assembly 40 is configured to provide a driving torque to drive the lever 30 to deflect. The rotating support seat 20 is, during assembly, fixed onto the turnout beam. Correspondingly, the push-pull assembly 40 can also be fixed to the turnout beam, and based on the push-pull assembly 40 a force can be applied to the lever 30. In order to meet rotation requirements of the lever 30, the push-pull assembly 40 can be configured in a variety of ways.
In some embodiments, the push-pull assembly 40 includes: an axial push-pull member 41, a push rod head 42, and a pin shaft 43. A body of the lever 30 is disposed with a waist-shaped hole 31 thereon.
The push rod head 42 is connected to an axial moving end of the axial push-pull member 41, and can be driven by the axial push-pull member 41 to reciprocate axially to perform push-pull operations. The pin shaft 43 is disposed on the push rod head 42. The pin shaft 43 is embedded in the waist-shaped hole 31, and a push-pull direction of the axial push-pull member 41 intersects with a direction of long axis of the waist-shaped hole 31, so that in a condition that a linear reciprocating movement of the push rod head 42 is ensured, the pin shaft 43 can be ensured to move along the waist-shaped hole 31 to push the lever 30 to deflect. Therefore, the driving operations are simple and efficient.
A position in which the push rod head 42 is relatively far away from the jointing plate 10 is an initial position, and in this condition, the jointing plate 10 is in a state of laying down for jointing. A position in which the push rod head 42 is relatively close to the jointing plate 10 is an action limit position of the axial push-pull member 41, and in this condition the jointing plate 10 is in a state of standing up for joint breaking. With a driving structure in which the waist-shaped hole 31 is provided to cooperate with the axial push-pull member 41, a deflection speed of the lever 30 can gradually reduce when jointing operations are performed, that is, the deflection speed is first fast and then slow, and the jointing operations are efficient and therefore the jointing plate 10 can be placed smoothly and slowly on the turnout beam and a rail beam to be connected with the turnout beam, to ensure a quality of the jointing. when a switching of the turnout beam is implemented and the jointing plate 10 is to be retracted, the deflection speed of the lever 30 gradually increases, that is, the deflection speed is first slow and then quick; therefore, the jointing plate 10 slowly start to move away from a surface of the rail beam, and then accelerates to move away, and then quickly move in position to adapt to a switching operation of the turnout beam, and therefore an operating efficiency is improved. Therefore, it is ensured that a stable and reliable process of laying down the jointing plate 10 to cover the gap is stable and reliable
Since the pin shaft 43 transmits an axial push-pull torque, and in order to ensure a stability and reliability of the axial push-pull torque, the push rod head 42 may be configured as a U-shaped bracket 42a, and the pin shaft 43 is rotatably embedded on two support arms of the U-shaped bracket 42a, thereby ensuring the stable force on the pin shaft 43. A bottom of the U-shaped bracket 42a is fixed on the axial push-pull member 41 for a stable connection.
In some embodiments, the axial push-pull member 41 may be configured as an electric push rod 41a. An end of the electric push rod 41a is connected to the push rod head 42. A rod body of the electric push rod 41a is driven to move axially by electromagnetism to achieve an application of axial push-pull force.
In some embodiments, the electric push rod 41a may be a specific push-pull member, and may also use action elements such as electric hydraulic cylinders and air cylinders which are not limited here.
In some embodiments, the lever 30 is driven to deflect through the axial push-pull member 41 and the lever 30 as well as the waist-shaped hole 31. In addition, it also can be configured as a motor, which cooperates with a reducer structure and a connecting rod. The connecting rod may be directly connected to the lever 30 to drive the lever 30 to deflect.
Referring to
The traveling rail jointing device is disposed at an end of the turnout beam body 50 and cooperates with a switching operation of the turnout beam body 50 to realize jointing operations between the turnout beam body 50 and a branch rail beam 60.
In order to reduce an impact of the jointing device on a flatness of a rail surface on the turnout beam body 50, a sink platform 51 may be opened and disposed on the rail surface of the turnout beam body 50. The rotating support seat 20 is disposed in the sink platform 51. The sink platform 51 is opened and disposed with a housing area 51a therein and the jointing plate 10 is placed in the housing area 51a, thereby preventing the rotating support seat 20 and jointing plate 10 from protruding from the rail surface of the turnout beam body 50, ensuring the flatness of the rail surface, and reducing an impact on a traveling of train.
The sink platform 51 is opened and disposed with a lever housing hole 52 therein that passes through the turnout beam body 50. The lever 30 is deflectably arranged in the lever housing hole 52, so that the axial push-pull member 41 can be fixed in the turnout beam body 50 and located below a rail surface of a traveling rail. The jointing plate 10 is placed on the rail surface of the traveling rail. Therefore, the jointing device, with its overall small scale and simple structure, can well adapt to an internal space of the turnout beam body 50. The jointing device can implement jointing operations through a simple deflection action within a range of slightly larger than 90 degrees, and can also efficiently and stably adapt to gaps of various specifications and shapes through the deflection of the jointing plate 10. Therefore requirements of jointing working conditions of the pivot-type suspended monorail multi-way turnout beam can be met.
In order to ensure a smooth undulation of the rail surface after jointing, a depth of the housing area 51a for the jointing plate 10 relative to the rail surface is equal to a thickness of the jointing plate 10, thereby ensuring that the rail surface of the traveling rail of the turnout beam is flat in a state that gaps are joined.
Referring to
An edge of the jointing plate 10 is disposed with an arc-shaped connecting section 11. The arc-shaped connecting section 11 can smoothly dock with a rail surface sink platform 61 of the branch rail beam 60. An arc-shaped structural form can adapt gaps with various angles and forms. A side wall of the rail surface sink platform 61 of the branch rail beam 60 is also configured in an arc shape.
In order to meet reliability requirements of a stressed state, the first end 32 of the lever 30 is welded to a bottom surface 14 and a side surface 13 of the jointing plate 10 respectively, thereby achieving a stable fixation.
The pivot-type suspended monorail multi-way turnout beam and the traveling rail jointing device thereof are provided according to some embodiments of the disclosure.

The jointing device can cover the gaps by laying down the jointing plate to meet jointing requirements for the gaps with various shapes and specifications, and has high reliability and adaptability. The jointing device can implement jointing through a way of deflecting the jointing plate, and therefore the jointing device has a simple structure and operation, and high efficiency and reliability.
