The middle part of the ear plate 18 is hinged to the end of the base 10. A movable clamp 17 is provided at the lower end of the ear plate 18, and a fixed clamp 16 adapted to the movable clamp 17 is also provided at the end of the base 10 near the movable clamp 17. A lateral moving part for moving the rail is provided at the other end of the base 10. It also includes a lifting chain assembly that cooperates with the movable clamp 17 and the fixed clamp 16. The lower end of the lifting chain assembly is provided with an openable clamp for clamping the rail. The lateral moving part includes a liner fixedly connected to the end of the base 10. An upper plate 14 extending laterally is provided on the upper part of the liner, and a lower plate is provided on the lower part of the liner. The upper plate 14 and the lower plate 16 are connected together. Vertical rollers 15 are rotatably arranged between the plates; a vertical plate 12 is arranged at the middle position of the lower part of the liner plate, and a horizontal roller 13 is rotatably arranged on one side of the vertical plate 12; the vertical rollers 15 and the horizontal rollers 13 are located on both sides of the vertical plate 12; a reinforcing plate 11 is fixedly arranged on the other side of the vertical plate 12; the lifting chain assembly includes a lifting ring 3 that can be clamped by a fixed clamp 16 and a movable clamp 17, and two lifting chains are connected to the lower part of the lifting ring 3. The lower ends of the two lifting chains are respectively connected to a first lifting clamp arm 5 and a shackle 9. The shackle 9 is hinged to a second lifting clamp arm 8. The middle parts of the first lifting clamp arm 5 and the second lifting clamp arm 8 are hinged together. The lower ends of the first lifting clamp arm 5 and the second lifting clamp arm 8 are fixedly connected to a clamping plate 6, and rollers 7 are rotatably connected to the inner side of the clamping plate 6; an upper connecting bracket 1 for connecting an excavator is fixedly arranged on the upper part of the base 10.

[0017] The first embodiment of this utility model is as follows: A rail mover includes a base 10, on which an upper connecting bracket 1 for connecting an excavator is fixedly mounted. The upper connecting bracket 1 includes two connecting ear plates, each with two ear holes. A pin passes through the ear holes and is connected to the stick of the excavator via the two pins. A hydraulic cylinder 19 and ear plates 18 are located in the space between the two connecting ear plates.

[0018] A base plate is provided on the upper part of the base 10. Two steel plates are vertically welded to the base plate to form a connecting structure. A hydraulic cylinder 19 is connected to the steel plate by a hinge. A rectangular opening is provided at the other end of the base plate. An ear plate 18 swings in the opening. The middle part of the ear plate 18 is connected to the end of the base 10 by a hinge. The connection point is located below the opening. The other end of the piston rod of the hydraulic cylinder 19 is connected to the upper end of the ear plate 18 by a hinge. A movable clamping mouth 17 is provided at the lower end of the ear plate 18. A fixed clamping mouth 16 that matches the movable clamping mouth 17 is also provided at the end of the base 10 near the movable clamping mouth 17. The movable clamping mouth 17 and the fixed clamping mouth 16 are corresponding protruding shapes, corresponding to the concave shape of the middle part of the rail. When the movable clamping mouth 17 and the fixed clamping mouth 16 rotate towards each other, they can clamp the middle part of the rail, thereby completing the clamping. The hinge between the ear plate 18 and the base 10 is achieved by a pin, and a retaining spring is installed on the pin to make it tend to rotate outward.

[0019] The rotation of the movable jaw 17 is controlled by the hydraulic cylinder 19. When the hydraulic cylinder 19 extends, it pushes the upper end of the ear plate 18 to move further away, thereby causing it to rotate. At this time, the movable jaw 17 moves toward the fixed jaw 16 to complete the clamping action. When the hydraulic cylinder 19 retracts, it pushes the upper end of the ear plate 18 to move closer, thereby causing it to rotate in the opposite direction. At this time, the movable jaw 17 moves away from the fixed jaw 16 to complete the release action.

[0020] The second embodiment of this utility model is as follows: Based on the description in Example 1, a second working mode is achieved by arranging other structures.

[0021] The other end of the base 10 is provided with a transverse moving part for moving the rail. The transverse moving part includes a liner plate fixedly connected to the end of the base 10. The liner plate is arranged vertically. The upper part of the liner plate is provided with a transversely extending upper plate 14, and the lower part of the liner plate is provided with a lower plate. A vertical roller 15 is rotatably arranged between the upper plate 14 and the lower plate. Specifically, a rotating shaft is set between the upper plate 14 and the lower plate. Bearings are embedded at both ends of the rotating shaft and connected to the hollow vertical roller 15 through the bearings, so that the vertical roller 15 can rotate smoothly on the rotating shaft. In a further embodiment, the vertical roller 15 is provided with a certain tilt angle, which is the same as the angle of the line connecting the rail head and the rail bottom edge, to ensure close contact with the rail.

[0022] A vertical plate 12 is installed in the middle of the lower part of the liner. A reinforcing plate 11 is fixedly installed on one side of the vertical plate 12 to enhance the structural strength. A horizontal roller 13 is rotatably installed on the other side of the vertical plate 12. Specifically, two steel plates are installed on the side of the vertical plate, and a rotating shaft is set between the two steel plates. Bearings are embedded at both ends of the rotating shaft and connected to the hollow horizontal roller 13 through the bearings, so that the horizontal roller 13 can rotate smoothly on the rotating shaft. The vertical roller 15 and the horizontal roller 13 are located on both sides of the vertical plate 12. It is worth noting that the horizontal tangent above the horizontal roller 13 extends beyond the uppermost edge of the vertical plate 12 to ensure that the rail can contact the horizontal roller 13 instead of the vertical plate 12, thus preventing wear.

[0023] During operation, the rail can be placed on the horizontal roller 13 so that it contacts the vertical roller 15, thus completing the on-site transport of the railway track. The vertical and horizontal rollers 13 provide low-resistance support, and the rail mover can easily move along the rail, thereby completing the movement and transport of the rail.

[0024] The third embodiment of this utility model is as follows: Based on the descriptions in Embodiments 1 and 2, a third working mode is achieved by arranging other structures.

[0025] A chain assembly is provided to cooperate with the clamp 2 to achieve a third function. The chain assembly includes a lifting ring 3 that can be clamped by the fixed clamp 16 and the movable clamp 17. When the movable clamp 17 contacts the end of the fixed clamp 16, it can clamp the lifting ring 3 in the space formed by the movable clamp 17 and the fixed clamp 16. Two chains are connected to the lower part of the lifting ring 3. The lower ends of the two chains are respectively connected to a first lifting arm 5 and a shackle 9. The shackle 9 is hinged to a second lifting arm 8. The middle parts of the first lifting arm 5 and the second lifting arm 8 are hinged to form an X-shaped structure. The first lifting arm 5... A clamping plate 6 is fixedly connected to the lower end of the second lifting clamping arm 8. A roller 7 is rotatably connected to the inner side of the clamping plate 6. Specifically, a rotating shaft is installed through the clamping plate 6, making the rotating shaft perpendicular to the clamping plate 6. Then, a bearing is embedded in the inner end of the rotating shaft and connected to the roller 7 through the bearing, so that the roller 7 can rotate in a plane parallel to the clamping plate 6. The roller 7 can contact the web of the rail and abut against the rail head, thereby clamping the rail. In practice, when the lifting chain moves upward, the two rollers 7 move towards each other through the action of the X-shaped structure to complete the clamping.

[0026] This clamping effect enables the hoisting of moving steel rails, achieving a third working mode.

[0027] In the above embodiments, bushings are installed at each hinge structure to increase wear resistance.

[0028] It should be noted that the terms "first, second, and third" used in this utility model are for descriptive purposes only and do not indicate any order. They should not be construed as indicating or implying relative importance, and can be interpreted as names.

[0029] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the principles, the implementation of the present invention may have any modifications or variations.
