Problems solved by technology
[0002] In railway transportation, a considerable part of the torque transmission of locomotive equipment is in the form of couplings. In maintenance work, it is often necessary to separate the connection of couplings. At present, two methods are mainly used. One is to make a certain part of the coupling The half-coupling is fixed, and the other half-coupling is pulled by traction equipment to separate the two half-couplings. This method is limited by the site and equipment, and cannot be implemented in many cases, and it is time-consuming, labor-intensive, and inefficient. Low; the second is to use a hammering tool to hammer one end of the coupling pin to make the pin withdraw and separate the two half-couplings. Most of the pins removed by this method are deformed and scrapped, and cannot be used again , and due to the vibration of hammering, it often causes other parts to loosen, and has a bad influence on the working environment
