[0025] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0026] like Figures 1 to 5As shown, the rail-carrying vehicle 100 of this embodiment includes a first traveling wheel 1, a second traveling wheel 2, a connecting shaft 3, a support hanger 4, and hook assemblies 5. The first traveling wheel 1 and the second traveling wheel 2 are spaced apart in a first horizontal direction. Both ends of the connecting shaft 3 are rotatably connected to the first traveling wheel 1 and the second traveling wheel 2, respectively. The support hanger 4 is rotatably mounted on the connecting shaft 3. Multiple hook assemblies 5 are spaced apart along a second horizontal direction on the support hanger 4. Each hook assembly 5 includes a first hook 501 and a second hook 502. Each of the first hook 501 and the second hook 502 is rotatably connected to the support hanger 4. The first hook 501 and the second hook 502 are positioned opposite each other for hooking the rail head of the rail 200. The first horizontal direction is perpendicular to the second horizontal direction. For example, the first horizontal direction and the second horizontal direction are as follows: Figures 1 to 3 As shown.

[0027] In this embodiment of the utility model, the rail transport vehicle 100 has a first traveling wheel 1 and a second traveling wheel 2 spaced apart in a first horizontal direction, enabling the rail transport vehicle 100 to travel stably and reducing the swaying and wear of the rail 200 during transportation. The connecting shaft 3 is rotatably connected to the traveling wheels at both ends, allowing the traveling wheels to rotate freely during movement, adapting to ground undulations and improving stability and flexibility. A support hanger 4 is rotatably mounted on the connecting shaft 3, allowing the support hanger 4 to be adjusted in angle as needed to accommodate the transportation requirements of the rail 200 at different heights and positions. Multiple hook assemblies 5 are spaced apart along a second horizontal direction on the support hanger 4. Each hook assembly 5 includes a first hook 501 and a second hook 502 for hooking the rail head of the rail 200. This design allows the rail 200 to be stably suspended on the rail transport vehicle 100, facilitating transportation.

[0028] The rail transport vehicle 100 of this embodiment transports the rails 200 by hooking them, avoiding rail wear and deformation caused by direct dragging and ensuring the flatness of the rails after connection. It also avoids the safety hazard of wire rope breakage due to obstruction during dragging, reducing on-site operational safety risks. The use of the rail transport vehicle 100 simplifies the rail 200 handling process, eliminating the need for complex auxiliary equipment and multiple devices, thus improving work efficiency. The rail transport vehicle 100 has a compact structure, occupying little operating space, which helps improve the versatility and efficiency of on-site operations. The rail transport vehicle 100 is highly adaptable and can be applied to the handling of different types and specifications of rails 200, demonstrating strong flexibility and broad application prospects.

[0029] In some embodiments, at least two hook assemblies 5 are spaced apart on both sides of the connecting shaft 3 along a second horizontal direction. By providing hook assemblies 5 on both sides of the connecting shaft 3, the rail transport vehicle 100 of this embodiment can achieve balance of the rail 200 during transport, reducing tilting or swaying caused by unilateral load-bearing. The hook assemblies 5 on both sides can distribute the weight of the rail 200, reducing the load borne by a single hook assembly 5, thereby reducing component damage caused by overload.

[0030] In some embodiments, the support hanger 4 is provided with a first hinge shaft 6 extending along a first horizontal direction, and the hook assembly 5 includes a connecting rod 503 and a second hinge shaft 504. One end of the connecting rod 503 is hinged to the first hinge shaft 6, and the second hinge shaft 504 is provided at the other end of the connecting rod 503 along a second horizontal direction. The top ends of the first hook 501 and the second hook 502 are both hinged to the second hinge shaft 504.

[0031] The first hinge shaft 6 extends along a first horizontal direction and is hinged to one end of the connecting rod 503. This design allows the connecting rod 503 to rotate or swing relative to the support hanger 4 in the first horizontal direction, increasing operational flexibility. Through the hinge action of the first hinge shaft 6, the hook assembly 5 can adapt to rails 200 at different heights, ensuring that the rails 200 can be firmly hooked and remain stable even on uneven ground. As part of the hook assembly 5, the connecting rod 503 connects the first hinge shaft 6 and the second hinge shaft 504, transmitting force and maintaining structural stability. The second hinge shaft 504 is located at the other end of the connecting rod 503 along a second horizontal direction, allowing the first hook 501 and the second hook 502 to swing freely relative to the connecting rod 503, better adapting to the shape and position of the rails 200. Through the design of the hinge shaft, the hook assembly 5 can adapt to various sizes and shapes of rails 200, increasing the adaptability and application range of the rail transport vehicle 100.

[0032] Optionally, the first hook 501 and the second hook 502 are arranged at intervals in the second horizontal direction. When handling multiple rails 200, the spaced hooks can reduce interference between the hooks, making the operation smoother.

[0033] In some embodiments, the first hook 501 is provided with a mounting plate 505 on one side in the second horizontal direction. The mounting plate 505 has a first through hole extending in the first horizontal direction, and the second hook 502 has a second through hole extending in the first horizontal direction. The hook assembly 5 includes a positioning pin 7, through which the first and second through holes are passed to limit the movement of the first hook 501 and the second hook 502 in the first horizontal direction.

[0034] The positioning pin 7 passes through the first and second through holes, thereby limiting the movement of the first hook 501 and the first hook 502 in the first horizontal direction and ensuring that their relative positions remain unchanged during transportation. The positioning pin 7 effectively prevents the hooks from swinging and shifting during transportation, increases the stability of the rail 200, increases the reliability of the entire hook assembly 5, and thus improves the safety of transporting the rail 200.

[0035] In some embodiments, one end of the positioning pin 7 is provided with a baffle, and the other end of the positioning pin 7 is provided with a third through hole that extends radially through it, the third through hole being used to install the pin 8.

[0036] A baffle is provided at one end of the positioning pin 7. This baffle prevents the positioning pin 7 from falling out after passing through the first and second through holes, ensuring that the positioning pin 7 remains in the correct position during handling. The main function of the latch 8 is to lock the positioning pin 7, preventing it from moving or rotating during handling and ensuring the stability of the hook assembly 5. The design of the latch 8 allows operators to quickly install and remove the positioning pin 7, improving work efficiency.

[0037] In some embodiments, the support hanger 4 has a push rod 9 at one end in the second horizontal direction, and the push rod 9 is perpendicular to the connecting shaft 3 and inclined upward.

[0038] The main function of push rod 9 is to provide thrust during the transportation of rail 200, and it can also be used to maintain the stability of support hanger 4 to facilitate the movement of rail 200. The push rod 9 makes the handling of rail 200 faster, eliminating the need for operators to manually drag rail 200 and improving work efficiency. The use of push rod 9 reduces the physical labor of operators when transporting rail 200, thus lowering labor intensity.

[0039] Optionally, the angle between the push rod 9 and the second horizontal direction is 15°-30°. For example, the angle between the push rod 9 and the second horizontal direction is 15°, 20°, or 30°. This provides the push rod 9 with a thrust direction that is neither too steep nor too gentle, so that the force of the push rod 9 can be used more effectively to push the rail 200 while reducing the stress on the push rod 9 itself.

[0040] In some embodiments, the support bracket 4 includes a frame 401, a first clamping plate 402, and a second clamping plate. The first clamping plate 402 and the second clamping plate are disposed opposite each other on the frame 401 along a first horizontal direction. A first clamping groove 4021 is formed on the bottom end surface of the first clamping plate 402, and a second clamping groove is formed on the bottom end surface of the second clamping plate. The first clamping groove 4021 and the second clamping groove are engaged on the connecting shaft 3, and the first clamping plate 402 and the second clamping plate are rotatable relative to the connecting shaft 3.

[0041] The design of the first and second slots ensures the stability of the connecting shaft 3, reducing the risk of rail 200 movement or hanger damage due to insecure connections during handling. The slot design simplifies the installation and disassembly of the connecting shaft 3, allowing operators to quickly assemble and disassemble the hanger. The plate design optimizes the hanger's space utilization, enabling more compact placement during rail 200 handling and saving space.

[0042] In some embodiments, the connecting shaft 3 is provided with a first baffle 10 and a second baffle 11. The first baffle 10 is disposed in the first horizontal direction on the side of the first clamping plate 402 away from the second clamping plate, and the second baffle 11 is disposed in the first horizontal direction on the side of the second clamping plate away from the first clamping plate 402.

[0043] The first baffle 10 and the second baffle 11 enhance the stability of the entire support frame 4 by restricting the movement of the clamping plate, making the rail 200 more secure during handling. The baffle design prevents the clamping plate from shifting due to impact or vibration during handling, ensuring the fixation between the clamping plate and the connecting shaft 3. The baffle also provides a certain degree of safety protection, preventing operators from coming into contact with the moving parts between the connecting shaft 3 and the clamping plate during handling, reducing the risk of accidental injury.
