[0093] Among them, the connecting ring 20181 is used to connect with the traction rope 2011. Such a configuration facilitates the installation of the traction rope 2011.

[0094] Furthermore, the telescopic member 20183 is disposed in the clamping portion 20182 , and a threaded hole is disposed on the side wall of the clamping portion 20182 , and the threaded hole is connected to the clamping groove 20184 .

[0095] Exemplarily, the telescopic member 20183 can be a telescopic column, the first end of the telescopic column is provided with an external thread, the external thread is screwed into the threaded hole, and the second end of the telescopic column is located outside the clamping portion 20182. During use, the long steel rail 30 is located in the clamping groove 20184. The second end of the telescopic column is adjusted so that the first end of the telescopic column presses against the long steel rail 30 in the clamping groove 20184, thereby further fixing the long steel rail 30 and preventing the long steel rail 30 from detaching from the clamping portion 20182.

[0096] In some embodiments, the telescopic member 20183 may also be a bolt, which cooperates with the threaded hole. The use process of the bolt is the same as that of the telescopic column, which will not be repeated here.

[0097] When unloading the long steel rail 30 on a slope, the working process of the traction device 201 in this embodiment is as follows: first, the clamping part 20182 is clamped on the long steel rail 30 to be unloaded, at this time, the piston rod of the hydraulic cylinder is extended, driving the driving rod 20136 to rotate, the driving rod 20136 drives the intermediate rod and the first connecting rod 20133 to rotate, and then the intermediate connecting rod 20135 drives the second connecting rod 20134 to rotate, the first connecting rod 20133 drives the first friction plate 20131 to contact with the damping column 2015, and the second connecting rod 20134 drives the second friction plate 20132 to contact with the damping column 2015, thereby preventing the rotation of the rotating shaft 2012, providing resistance for the rotation of the rotating shaft 2012, and facilitating the unloading of the long steel rail 30. After the unloading of the rail 30 is completed, the clamping part 20182 is separated from the long rail 30, and then the piston rod of the hydraulic cylinder is retracted, thereby driving the driving rod 20136 to rotate, and the driving rod 20136 drives the intermediate connecting rod 20135 and the first connecting rod 20133 to rotate, and then the intermediate connecting rod 20135 drives the second connecting rod 20134 to rotate, and the first connecting rod 20133 drives the first friction plate 20131 to separate from the damping column 2015, and the second connecting rod 20134 drives the second friction plate 20132 to separate from the damping column 2015, and the rotating shaft 2012 is driven to rotate by the driving motor 2016, and then the traction rope 2011 is wound around the winch drum 2017, completing the unloading of the long rail 30 on the slope.

[0098] Continue to refer to Figure 1-Figure 8 In other embodiments, a rail transport vehicle 1 is also provided, including a flatbed vehicle body 10 and a rail support 20; in this configuration, the rail support 20 is used to carry the long rails 30, thereby facilitating the transportation of the long rails 30.

[0099] A hydraulic pump 40 is provided on the flatbed vehicle body 10, and the hydraulic pump 40 is used to provide power for the hydraulic cylinder.

[0100] Furthermore, the structure and working process of the rail support 20 are described in detail in the above embodiments, and will not be described in detail here.

[0101] In this embodiment, the rail transport vehicle 1 includes a flatbed body 10 and a rail support 20, the rail support 20 is located on the flatbed body 10, and the first column 202 and the second column 203 are connected to the flatbed body 10. Exemplarily, the first column 202 and the second column 203 can be connected to the flatbed body 10 by bolt connection or welding, and there is no limitation on this.

[0102] The rail transport vehicle 1 provided in this embodiment includes a flatbed vehicle body 10 and a rail support 20, wherein the rail support 20 includes a support body equipped with a traction device 201 and for holding a long rail 30; the traction device 201 is arranged on the support body, and the traction device 201 includes a traction rope 2011, a rotating shaft 2012 and a damping device 2013, wherein the rotating shaft 2012 is rotatably connected to the support body, one end of the traction rope 2011 is wound around the rotating shaft 2012, and the other end of the traction rope 2011 is used to connect with the long rail 30; the damping device 2013 is connected to the rotating shaft 2012 to provide resistance to the rotation of the rotating shaft 2012; when the long rail 30 is unloaded on a slope, the traction rope 2011 is connected to the long rail 30, and the damping device 2013 prevents the rotating shaft 2012 from rotating, and provides resistance to the rotating shaft 2012, so that the long rail 30 slowly slides out of the installation groove, thereby preventing the long rail 30 from sliding too fast, thereby improving safety.
