It is usually forged from high-strength alloy steel, possessing a robust bar body and a flexible joint structure, enabling it to work stably under complex operating conditions.

[0003] The existing tow bar is not easy to assemble and disassemble flexibly, and the convenience of maintenance and replacement needs to be improved. At the same time, its tensile, compressive and shock absorption performance needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a pressure-resistant forged train traction rod structure that can be flexibly disassembled and repaired, with strong tensile and compressive strength and shock absorption performance, and high practicality.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

A second rod segment is inserted into the connecting cavity. Two first pin holes are respectively provided on the symmetrical side surface of the first rod segment, and two pin slots are respectively provided on the symmetrical side surface of the second rod segment. First pin rods are inserted into the first pin holes and pin slots. A first shock absorber is fixedly connected to the inner end face of the connecting cavity, and a second shock absorber is fixedly connected to the inner end face of the second rod segment.

[0007] By adopting the above technical solution, disassembly and assembly operations can be carried out flexibly and conveniently. In subsequent use, maintenance operations can be carried out flexibly, making it highly practical.

[0008] Furthermore, one end of the first shock absorber is fixedly connected to a first linkage block, and the end of the second rod segment abuts against the outer surface of the first linkage block.

[0009] By adopting the above technical solution, it is ensured that the first shock absorber can perform effective shock absorption operation.

[0010] Furthermore, one end of the second shock absorber is fixedly connected to a second linkage block, and the first pin rod is attached to the outer surface of the second linkage block.

[0011] By adopting the above technical solution, it is ensured that the second shock absorber can perform effective shock absorption operation.

[0012] Furthermore, a second pin hole is provided on the side surface of the first pin rod, and a second pin rod is inserted into the second pin hole.

[0013] By adopting the above technical solution, the positional stability of the first pin can be improved by using the second pin.

[0014] Furthermore, a through hole is provided on one end side surface of the second pin rod, and a locking pin is installed inside the through hole.

[0015] By adopting the above technical solution, the positional stability of the second pin can be effectively improved.

[0016] Furthermore, both the first and second shock absorbers consist of a hydraulic damper and a spring, with the spring sleeved on the outside of the hydraulic damper.

[0017] By adopting the above technical solution, efficient shock absorption can be achieved through the cooperation of hydraulic dampers and springs.

[0018] In summary, the beneficial technical effects of this utility model are as follows:

[0019] This invention allows for the assembly of the first and second rod segments during use. During assembly, the second rod segment is inserted into the connecting cavity of the first rod segment, with its end fitting against the outer surface of the first linkage block. Next, the first pin is inserted into the first pin hole and pin through slot, and then the second pin is inserted into the second pin hole. Finally, a locking pin is installed in the through hole of the second pin, with the first pin fitting against the outer surface of the second linkage block. This allows for shock absorption during the pulling and compressing actions of the traction rod using the first and second shock absorbers, effectively improving the traction rod's compressive and tensile strength. Furthermore, the modular structure facilitates convenient replacement of damaged components during subsequent use, significantly enhancing its practicality. Attached Figure Description

[0023] The method of this utility model will be further described in detail below with reference to the accompanying drawings.

[0024] Reference Figure 1 , Figure 2 A pressure-resistant forged train traction rod structure includes a first rod segment 1, with a connecting cavity 3 at one end of the first rod segment 1. A second rod segment 7 is inserted inside the connecting cavity 3. Two first pin holes 2 are respectively provided on the symmetrical side surfaces of the first rod segment 1, and two pin slots 8 are respectively provided on the symmetrical side surfaces of the second rod segment 7. A first pin rod 12 is inserted inside the first pin holes 2 and the pin slots 8. A first shock absorber 9 is fixedly connected to the inner end face of the connecting cavity 3, and a second shock absorber 10 is fixedly connected to the inner end face of the second rod segment 7. Both the first shock absorber 9 and the second shock absorber 10 are composed of a hydraulic damper 4 and a spring 5. The spring 5 is sleeved on the outside of the hydraulic damper 4. A second pin hole is provided on the side surface of the first pin rod 12, and a second pin rod 13 is inserted inside the second pin hole. A through hole is provided on the side surface of one end of the second pin rod 13. The unit is equipped with a locking pin 14, which allows for the assembly of the first rod segment 1 and the second rod segment 7 during use. During assembly, the second rod segment 7 is inserted into the connecting cavity 3 of the first rod segment 1, so that the end of the second rod segment 7 is attached to the outer surface of the first linkage block 6. Then, the first pin rod 12 is inserted into the first pin hole 2 and the pin through groove 8. Then, the second pin rod 13 is inserted into the second pin hole. Next, the locking pin 14 is installed in the through hole of the second pin rod 13. At this time, the first pin rod 12 is attached to the outer surface of the second linkage block 11. At this time, the first shock absorber 9 and the second shock absorber 10 can be used to perform shock absorption when the traction rod is pulled or compressed, which effectively improves the compressive and tensile performance of the traction rod. At the same time, the modular structure allows for convenient replacement of damaged parts during subsequent use, which effectively improves the practicality.

[0025] Reference Figure 1 , Figure 2 One end of the first shock absorber 9 is fixedly connected to the first linkage block 6, and the end of the second rod segment 7 abuts against the outer surface of the first linkage block 6. One end of the second shock absorber 10 is fixedly connected to the second linkage block 11, and the first pin rod 12 is attached to the outer surface of the second linkage block 11. Under tension, the second rod segment 7 moves to the outside of the connecting cavity 3. At this time, the first pin rod 12 can obstruct the movement of the second linkage block 11 and thus compress the second shock absorber 10, which can perform tensile shock absorption. Under compression, the second rod segment 7 moves to the inside of the connecting cavity 3. At this time, the second rod segment 7 abuts against the outer surface of the first linkage block 6 and compresses the first shock absorber 9, which can then be used for compression shock absorption.

[0026] Working principle: In use, the first rod segment 1 and the second rod segment 7 are assembled. During assembly, the second rod segment 7 is inserted into the connecting cavity 3 of the first rod segment 1, so that the end of the second rod segment 7 is attached to the outer surface of the first linkage block 6. Then, the first pin 12 is inserted into the first pin hole 2 and the pin through groove 8. Then, the second pin 13 is inserted into the second pin hole. Finally, the locking pin 14 is installed in the through hole of the second pin 13. At this time, the first pin 12 is attached to the outer surface of the second linkage block 11. On the surface, it can be used normally after assembly. During use, when under tension, the second rod segment 7 moves to the outside of the connecting cavity 3. At this time, the first pin rod 12 can obstruct the movement of the second linkage block 11, and thus can compress the second shock absorber 10. At this time, tensile shock absorption operation can be performed. When under compression, the second rod segment 7 moves to the inside of the connecting cavity 3. At this time, the second rod segment 7 abuts against the outer surface of the first linkage block 6 and compresses the first shock absorber 9. At this time, the first shock absorber 9 can be used for compressive shock absorption operation.
