[0003] At present, the assembly process of the railway freight car coupler buffer device is to pre-assemble the hook tail frame, buffer, and hook from the plate into a whole before loading, and then assemble the supporting parts such as the support beam and the support plate. When loading, a crane is used to lift the hook tail frame assembly to the support surface of the coupler buffer device. The operator manually operates the jack below the support surface to lift the hook tail frame assembly to the position of the lower wing surface of the middle beam, and then manually lifts the support beam, the support plate and other supporting parts to the corresponding position of the middle beam and tightens them with bolts and nuts. Then, the jack is manually operated to lower the coupler buffer device support to complete the assembly operation. The entire assembly process is complicated and the operation time is long. In addition, due to the heavy weight of the hook tail frame assembly, the lifting and lowering distance is large, resulting in high labor intensity and low operation efficiency in the entire operation process.
