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.
