Embodiment Construction
[0025] Such as Figure 1-4 As shown, the embodiment of the present invention provides a telescopic connecting rod for a trailer, including a connecting rod body 1, and both ends of the connecting rod body 1 are provided with hanging rings; at least one hanging ring can slide axially relative to the connecting rod body 1 The movable hanging ring 2; the hanging ring at the left end of the connecting rod body 1 is the fixed hanging ring 3 in this embodiment, and the hanging ring at the right end of the connecting rod body 1 is the movable hanging ring 2, and the movable hanging ring 2 has a ring for blocking The end 1a of the connecting rod body (the end 1a of the connecting rod body is the end of the connecting rod body 1 close to the movable hanging ring 2) moves and defines the hanging ring stopper where the movable hanging ring 2 shrinks axially relative to the connecting rod body 1 21. The end 1a of the connecting rod body has a connecting rod stopper 11 for blocking the mov...

The invention provides a telescopic connecting bar for trailers. The telescopic connecting bar comprises a connecting bar body. Two ends of the connecting bar body are both provided with hanger rings; at least one hanger ring is a moving hanger ring. Each moving hanger ring is provided with a hanger ring stop part. The end, close to the moving hanger rings, of the connecting bar body is provided with a connecting bar stop part hinged to a locking block. The end of the locking block is provided with a transition face which rotates with the locking block to match with the hanger ring stop parts so as to lock the moving hanger rings. The moving hanger rings can telescope in relation to the connecting bar body, so that the problem when parking space between an electric locomotive and a trailer is inaccurate, the need for manual hooking in the startup state of the electric locomotive causes potential major safety hazards is solved; the length of the connecting bar can be adjusted through telescoping the moving travel, hooking is smoothly performed in the stop state of the electric locomotive accordingly, safety hazards in hooking operations are greatly decreased, and operations are facilitated.
Description
technical field [0001] The invention relates to the technology of pulling a mine trailer, in particular to a telescopic connecting rod for a trailer. Background technique [0002] Coal mine trailers usually need to be pulled by an electric locomotive during operation. The electric locomotive and the trailer are connected by rigid connecting rods. The length of the hook is the same, either big or small, and the operator cannot complete the hooking operation under static conditions. During actual operation, the operator has to drive the electric locomotive to adjust the distance between the two cars while hooking, so as to complete the process of hooking. [0003] There are potential safety hazards in the above-mentioned hooking operation process, which seriously violates the transportation management regulations and the relevant coal mine management system regulations, but in actual operation, this kind of illegal operation cannot be eliminated.
