A kind of coupler and its anti-jump device

Abstract

The invention provides a car coupler and an anti-bouncer of the car coupler. The car coupler and the anti-bouncer can improve anti-bouncing reliability. The anti-bouncer comprises an elastic piece which is connected with a lower lock pin rod of the car coupler. When the lower lock pin rod moves in the uncoupling direction, the elastic piece generates elastic deformation to prevent the lower lock pin rod from moving. When the car coupler vibrates or turnover operation is conducted, due to prevention of the elastic piece, the car coupler can still be kept in a lock state and prevented from being abnormally uncoupled. When the car coupler needs to be uncoupled, a car coupler lifting rod with the long arm of force can be utilized to drive the lower lock pin rod to move in the uncoupling direction, so that the car coupler can be conveniently kept in an uncoupling state and normal uncoupling can not be greatly affected. Therefore, the elastic piece can be arranged on the car coupler no matter when uncoupling is conducted or when the car coupler is in the lock state, and the elastic piece does not need to be mounted or demounted according to the operating condition of the car coupler. The car coupler and the anti-bouncer are simple in structure and can achieve both anti-bouncing reliability and operation convenience.

Description

technical field [0001] The invention relates to the technical field of railway vehicles, in particular to an anti-jump device of a coupler. The invention also relates to a coupler with the above-mentioned anti-jump device. Background technique [0002] The carriages of railway vehicles are connected by couplers, and the force is transmitted through the couplers. During the operation of the vehicle, if there is an abnormal uncoupling of the coupler, it will cause accidents such as train separation, and in severe cases, it will also affect the normal transportation efficiency and transportation order of the railway. Therefore, it is particularly important to prevent the abnormal uncoupling of the coupler, which plays a vital role in improving the efficiency and safety of railway transportation. [0003] Please refer to Figure 1-3 , figure 1 It is a schematic diagram of the side structure of the vehicle coupler in a specific embodiment in the prior art; figure 2 for fi...

Problems solved by technology

[0010] The latch 181' has deformation and failure problems caused by its own strength and human factors during use; before the coupler is uncoupled, the latch 181' needs to be pulled out manually, and after the coupler is locked, the latch 181 needs to be manually pulled out. 'Insert into the through hole 161' of the lower lock pin rod 16', the above operation increases the workload of the operator to a certain extent and reduces the working efficiency; in addition, the insertion and extraction of the above latch 181' are all performed at the end of the carriage connection , there is a greater security risk
