[0027] like Figures 1 to 5 As shown, a sleeper flatbed transport trolley includes a car body, on which a traction component is provided. The traction component is used to drag the sleeper onto the car body so that the car body can drive the sleeper to move along the track for transportation.

[0028] By configuring the vehicle body and traction components, rotating the traction components allows a single person to drag the sleepers onto the flatbed transport trolley. One person pushes the trolley while another provides safety protection, completing the sleeper transport. This solves the problems of high manpower requirements, low transport efficiency, and high labor intensity in sleeper transport operations, while also eliminating the safety hazard of sleepers accidentally slipping and injuring people during handling.

[0029] In this embodiment of the sleeper flatbed transport trolley, the vehicle body includes a support frame 1, and a first rolling rod 2 is provided on the support frame 1. The traction component is located at one end of the support frame 1 to drag the sleeper, thereby driving the first rolling rod 2 to roll and move onto the vehicle body.

[0030] Specifically, the support frame 1 is a rectangular frame used to support the first rolling rod 2 and the sleeper. By setting the first rolling rod 2, when the traction component drives the sleeper to contact the support frame 1, the sleeper moves horizontally on the support frame 1 and drives the first rolling rod 2 to roll, thereby reducing the sleeper's movement resistance and facilitating the traction of the sleeper. At the same time, the first rolling rod 2 can play a certain guiding role for the sleeper when it rolls.

[0031] The design makes the sleeper transport flat car have enough bearing capacity and stability, reduces friction and wear of the car during operation.

[0032] In the sleeper flat transport car of the embodiment, the first rolling rod 2 is provided with several first rolling rods 2 and is rotatably connected with the support frame 1, and the several first rolling rods 2 are equidistantly distributed along the extension direction of the support frame 1 to uniformly support the sleepers.

[0033] Through the above arrangement, the support effect of the first rolling rod 2 on the sleeper is ensured, the arrangement direction of the several first rolling rods 2 is parallel to the direction of the sleeper movement dragged by the traction assembly, and the distance between the adjacent two first rolling rods 2 matches the length of the sleeper, so that the sleeper is prevented from falling or turning over to affect the normal traction.
