[0002] Track maintenance is a key part of railway maintenance, and its core goal is to ensure the stability and safety of the track. Shim replacement is a common task in track maintenance. Shims are installed between rails and sleepers. Their main function is to buffer the impact of trains during operation and maintain the elastic properties of the track. When replacing the gaskets, maintenance personnel must first remove the fasteners, and then manually lift the rails with the help of professional track-lifting tools to ensure that the rails are lifted smoothly to an appropriate height so that the damaged gaskets can be replaced and adjusted smoothly. After the replacement is completed, the rails are slowly lowered, the fasteners are retightened, and the work site is cleaned up. The entire process requires not only professional technical capabilities of the operators, but also strict compliance with safety regulations to ensure the stability of the track and the safety of train operation.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] like Figure 1-11 As shown, a railway maintenance tool comprises a track traveling vehicle 1 and a track supporting vehicle 2. The track traveling vehicle 1 and the track supporting vehicle 2 are respectively arranged on two rails.

[0022] The rail travel vehicle 1 is connected to the rail support vehicle 2 via a connecting shaft 3, one end of the connecting shaft 3 is fixedly connected to the rail travel vehicle 1, and the other end of the connecting shaft 3 is connected to the rail support vehicle 2 via a ball joint 30. That is, after the rail under the rail support vehicle 2 is lifted, the angle can be changed accordingly through the setting of the ball joint, thereby reducing the impact on the stability of the rail travel vehicle 1 and preventing the rail travel vehicle 1 from overturning.

[0023] A rail clamping mechanism 4 is provided on the rail traveling vehicle 1 , and the rail clamping mechanism 4 can clamp the rails below the rail traveling vehicle 1 , thereby playing a role in fixing the rail traveling vehicle 1 .

[0024] A mounting plate 5 is slidably connected to the connecting shaft 3, and a first driving cylinder 6 is provided between the mounting plate 5 and the rail traveling vehicle 1; a bolt disassembly assembly 7 is provided on the mounting plate 5; the rail bolts located under the rail supporting vehicle 2 are disassembled or installed through the bolt disassembly assembly 7.

[0025] The rail traveling vehicle 1 is fixedly connected with a telescopic frame 8, and a rail lifting assembly 9 is arranged on the telescopic frame 8; the rail located under the rail supporting vehicle 2 is lifted by the rail lifting assembly 9.

[0026] When in use, the track traveler 1 and the track support vehicle 2 move along the track; when the bolt disassembly assembly 7 moves above the track bolt, it is disassembled. Multiple groups of track bolts are disassembled as needed to ensure that the rails under the track support vehicle 2 have enough space for movement.

[0027] When the multiple groups of bolts under the track support vehicle 2 are removed, the first drive cylinder 6 is retracted, so that the bolt disassembly assembly 7 is moved close to the track travel vehicle 1. The telescopic frame 8 is extended to move the rail lifting assembly 9 to the track support vehicle 2, and the rail under the track support vehicle 2 is lifted by the rail lifting assembly 9.

[0028] Due to the ball-jointed connection, when the rails under the track support vehicle 2 are lifted, the angle thereof will change relative to the connection shaft 3, which can reduce the impact on the track travel vehicle 1. Moreover, after disassembly, the bolt disassembly assembly 7 will be retracted to a position close to the track travel vehicle 1; and the rail lifting assembly 9 is connected to the track travel vehicle 1. That is, during the lifting process of the rails under the track support vehicle 2, the main weight on it is the track travel vehicle 1.

[0029] Furthermore, the rail clamping mechanism 4 includes a clamping plate 40 and a transmission gear 41. Two clamping plates 40 are provided. The two clamping plates 40 are arranged opposite to each other and are both slidably connected to the rail vehicle 1. A first return spring 42 is provided between the clamping plate 40 and the rail vehicle 1. When the clamping plate 40 moves toward the rail vehicle 1, the first return spring 42 is compressed to generate elastic potential energy.

[0030] The transmission gear 41 is rotatably connected to the rail travel vehicle 1, and a driving rack 43 meshing with the transmission gear 41 is fixed on both clamping plates 40, and the transmission gear 41 is located between the two driving racks 43. That is, when any clamping plate 40 moves, the other clamping plate 40 will also move accordingly through the cooperation between the driving rack 43 and the transmission gear 41, thereby realizing the relative or opposite movement of the two clamping plates 40.

[0031] A push plate 44 is fixedly connected to the mounting plate 5; when the first drive cylinder 6 is retracted, the mounting plate 5 is driven to move toward the direction of the rail vehicle 1, so that the push plate 44 contacts the adjacent clamping plate 40 and pushes the clamping plate 40 to move toward the direction of the rail vehicle 1. The two clamping plates 40 move relative to each other to clamp the rails under the rail vehicle 1. Through the above-mentioned structural setting, linkage can be achieved; that is, when the first drive cylinder 6 is retracted and the rail is ready to be lifted by the rail lifting assembly 9, the clamping plate 40 clamps the rails, which plays a role in fixing the rail vehicle 1 when the rails are lifted.

[0032] When removing the bolts or moving the whole along the track, the first drive cylinder 6 is in an extended state; at this time, the push plate 44 is not released from the adjacent clamping plate 40, and the elastic potential energy is released by the first return spring 42, so that the two clamping plates 40 move away from each other to loosen the rail under the track vehicle 1.

[0033] Furthermore, a limiting wedge 10 is fixedly connected to the track support vehicle 2, and a limiting plate 11 is fixed to the mounting plate 5. The limiting plate 11 is provided with an open slot that matches the limiting wedge 10. During the movement, the first driving cylinder 6 is extended so that the open slot on the limiting plate 11 is plugged into the limiting wedge 10, which can limit the movement of the ball joint and prevent the track support vehicle 2 from moving at will during the movement or bolt removal process.

[0034] Furthermore, the bolt disassembly assembly 7 includes a horizontal moving mechanism 70, a vertical moving mechanism 71 and a bolt wrench 72; the fixed portion of the horizontal moving mechanism 70 is fixedly connected to the mounting plate 5, the fixed portion of the vertical moving mechanism 71 is fixedly connected to the moving portion of the horizontal moving mechanism 70; the bolt wrench 72 is connected to the moving portion of the vertical moving mechanism 71 through a connecting assembly. The bolt wrench 72 is driven to move horizontally by the horizontal moving mechanism 70, and the bolt wrench 72 is driven to move vertically by the vertical moving mechanism 71.

[0035] The horizontal moving mechanism 70 and the vertical moving mechanism 71 can both use linear motors, the fixed part of which refers to the fixed seat, and the movable part refers to the movable seat. Through the cooperation of the horizontal moving mechanism 70 and the vertical moving mechanism 71, the bolt wrench 72 can be moved above the track bolt to be removed. The bolt wrench 72 is driven downward by the vertical moving mechanism 71 to connect with the track bolt for removal. During the removal process, the track bolt will move upward, so the vertical moving mechanism 71 also moves upward accordingly.

[0036] Further, the connecting assembly includes a fixed frame 73 and a movable frame 74, the fixed frame 73 is fixedly connected to the moving part of the vertical moving mechanism 71, the movable frame 74 is slidably connected to the fixed frame 73, a second return spring 75 is provided between the movable frame 74 and the fixed frame 73, and the bolt wrench 72 is fixedly connected to the movable frame 74. By providing the second return spring 75, a buffering effect can be played when the vertical moving mechanism 71 drives the bolt wrench 72 to move downward and contact with the rail bolt connection.

[0037] Furthermore, the rail lifting assembly 9 includes a rail lifting cylinder 90 and a connecting bracket 91; the connecting bracket 91 is slidably connected to the end of the telescopic frame 8, and a second driving cylinder 92 is provided between the connecting bracket 91 and the telescopic frame 8; a support plate 93 is fixed to the lower end of the connecting bracket 91, the piston rod of the rail lifting cylinder 90 is fixedly connected to the support plate 93, and a rail lifting rod 94 is fixed on the cylinder body of the rail lifting cylinder 90.

[0038] When the rail needs to be lifted, the second driving cylinder 92 is retracted to make the rail lifting rod 94 lower than the lower surface of the rail; then the rail lifting cylinder 90 is moved by pulling the telescopic frame 8 until the rail lifting rod 94 is located below the rail. After that, the second cylinder telescopic cylinder is further retracted to make the support plate 93 contact the ground; finally, the piston rod of the rail lifting cylinder 90 is extended, and the rail is lifted through the rail lifting rod 94 to replace the gasket.

[0039] Furthermore, a hanging plate 95 is rotatably connected to the rail support vehicle 2. When the rail lifting cylinder 90 is moved by pulling the telescopic frame 8 so that the rail lifting rod 94 is located below the rail, the end of the rail lifting rod 94 will be connected to the connection hole on the hanging plate 95. That is, the rail lifting rod 94 can be supported by the hanging plate 95 to prevent the end of the rail lifting rod 94 from being suspended in the air, thereby preventing the rail lifting rod 94 from bending during the rail lifting process.

[0040] Furthermore, during the bolt removal process, the end of the rail lifting rod 94 should not be supported. Therefore, a support limit rod 96 for limiting the rotation of the hanging plate 95 is provided on the rail support vehicle 2. The hanging plate 95 is rotated counterclockwise to make the hanging plate 95 contact the support limit rod 96, thereby supporting the hanging plate 95 so that the hanging plate 95 is placed horizontally. When lifting the rail, the hanging plate 95 is rotated clockwise to make it vertical, and the connecting hole on it is opposite to the rail lifting rod 94.

[0041] Furthermore, the rail traveling vehicle 1 includes a traveling frame 12 and an electric rail wheel 13 , and the electric rail wheel 13 is arranged on the traveling frame 12 ; the rail supporting vehicle 2 includes a supporting frame 14 and a rail wheel 15 , and the rail wheel 15 is rotatably connected to the supporting frame 14 .

[0042] Only the preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the above embodiments.
