Then, fix the clamping component 4 through the fixing component 5. Then, clamp and fix the pipes through the clamping component 4. The bent ends of the pipes can be vertically placed between the support rods 2 on both sides. Then, connect the adjacent two bent ends through the connecting component 3. By clamping and fixing the pipes and connecting the adjacent two bent ends through the connecting component 3, the collision and extrusion of the pipes during the transportation process can be effectively avoided, and the influence of the transportation process on the installation of the pipes can be reduced.

[0040] Referring to Figure 1 , Figure 2 , the clamping component 4 in this embodiment includes an elastic clamping block 41. The clamping block 41 is made of rubber material. Two clamping parts 411 are provided on the clamping block 41, and a clamping groove 412 for the pipe to be inserted is formed between the two clamping parts 411. The two clamping parts 411 can clamp and fix the pipe. The size of the clamping groove 412 can be set according to the different pipe diameters. Arc-shaped grooves that fit the pipes are provided on the opposite sides of the two clamping parts 411. On the one hand, it can increase the contact area between the clamping part 411 and the pipe, improve the uniformity of the force on the pipe, and on the other hand, it can limit the pipe and improve the stability of the pipe clamping and fixing.

[0041] Referring to Figure 1 , Figure 2, a sliding groove 21 is provided on each support rod 2 along its length direction.

The fixing bolt 51 can drive the fixing piece 52 to move towards the strip-shaped hole 23, so that the sliding portion 413 is tightly pressed and fixed on the groove wall of the sliding groove 21.

[0043] When the clamping block 41 slides on the support rod 2, the clamping block 41 drives the fixing bolt 51 to slide in the strip-shaped hole 23. After the position of the clamping block 41 is adjusted, the operator screws the fixing bolt 51. The head of the fixing bolt 51 abuts against the side surface of the support rod 2, and then continues to screw the fixing bolt 51. The fixing bolt 51 drives the fixing piece 52 to tightly press and fix the sliding portion 413 on the groove wall of the sliding groove 21, realizing the fixation of the clamping block 41 on the support rod 2 and improving the flexibility of the position adjustment of the clamping block 41; through the setting of the fixing piece 52, the stability of the abutting and fixing of the sliding portion 413 and the groove wall of the sliding groove 21 is improved.

The cooperation between the right-angle base 71 and the right-angle limiting plate 72 on the adjacent tooling rack 1 restricts the sliding of the adjacent two tooling racks 1, thereby improving the stability of the tooling racks 1 stacked on each other.

[0047] The implementation principle of a pipe clamping device for rail vehicles in an embodiment of the present application is as follows: When transporting pipes, the clamping block 41 drives the fixing bolt 51 to slide in the strip-shaped hole 23 to adjust the position of the clamping block 41 to adapt to the placement of pipes with different bending shapes. After the position of the clamping block 41 is adjusted, the operator screws the fixing bolt 51. The head of the fixing bolt 51 abuts against the side surface of the support rod 2, and then continues to screw the fixing bolt 51. The fixing bolt 51 drives the fixing piece 52 to tightly press and fix the sliding part 413 against the groove wall of the sliding groove 21, realizing the fixation of the clamping block 41 on the support rod 2. Then, the pipe is inserted into the clamping groove 412, and the pipe is clamped and fixed by the two clamping parts 411. The bent end of the pipe can hang between the two side support rods 2 to reduce the occupied space of the pipe in the horizontal direction. The elastic ring 31 is sleeved on the bent end of the pipe where it hangs, and they are connected by the flexible rod 32. Through the clamping and fixing of the pipe and the connection of the flexible rod 32 between the adjacent two bent ends, the collision and extrusion of the pipe during transportation can be effectively avoided, and the impact on the installation of the pipe during transportation can be reduced.
