A kind of automatic coupler for EMU leading car

Abstract

The invention provides an automatic vehicle hook for a motor train unit traction vehicle. The automatic vehicle hook comprises the traction vehicle, a locking mechanism for connecting and locking the motor train unit vehicle hook, a device for lifting and pulling the locking mechanism, a gravity balance device for adjusting lifting of the locking mechanism and a slide way for lifting of the locking mechanism. The slide way is of a box iron structure and fixed to the traction vehicle, one end of the device for lifting and pulling the locking mechanism is fixed to the slide way, the other end of the device is connected with the front end of the locking mechanism, and the locking mechanism is connected with the gravity balance device for adjusting lifting of the locking mechanism through a pulley type floating connection plate. According to the automatic vehicle hook, manual operation is not needed, the labor intensity of workers can be remarkably lowered, and meanwhile the work risk caused by manual vehicle pushing in a high-low platform, a ditch and the like is greatly lowered; eight persons were needed to work jointly to push the traction vehicle each time before while now, only one person is needed to push the traction vehicle, production efficiency is improved, the industrial automated level of the motor train unit manufacturing process is increased, traction and braking reliability is higher, and the damage risk is avoided.

Description

technical field [0001] The invention relates to a tow coupler of a rail vehicle. Background technique [0002] Due to the particularity of the semi-permanent coupler structure of the EMU, there is currently no tractor coupler used in conjunction with the semi-permanent coupler. During the manufacturing process of the EMU, the single weighing process needs to be repeatedly weighed 8 times, and each time it needs to be separated from the tractor and weighed. And the movement on the railway between the process stations is driven by manpower, and the brake method is used for braking. The disadvantage is that the labor intensity is high, the manpower waste is serious, and the automation level of the process is low. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an automatic towing coupler connected with the semi-permanent coupler of the EMU and the false coupler of the aluminum car body, which solves the problems of high labor intensity, wa...
