The metallurgical vehicle has a hook device (hook device and hook device), wherein the main purpose of the coupler is to achieve the connection between metallurgical vehicles, transmit traction and impact force, and keep a certain distance between metallurgical vehicles.
[0003] The coupler needs to withstand huge traction or impact force. The coupler body itself has sufficient strength to ensure that the coupler is not broken or crushed under huge force. The coupling or uncoupling between the couplers is achieved through a set of locking pin mechanisms in the coupler body to meet the requirements of vehicle marshaling. Among them, the lifting rod is a Z-shaped rod body. Manual uncoupling is achieved by pulling the coupler lifting rod, which moves the locking pin mechanism. After a certain stroke, the coupler tongue opens. The uncoupling process is the process of the coupler lifting rod, locking pin mechanism, and coupler tongue working together.
