However, the bolt, nut and other fasteners are often subjected to sunlight and rainwater, and thus the fasteners are prone to corrosion and need to be replaced frequently. However, when the fasteners are replaced at present, the equipment fasteners can be replaced only when the equipment is lifted, and thus the replacement of the fasteners must be performed by using a tool capable of lifting the equipment, and the replacement process is difficult and complex.

[0003] In order to solve the above technical problems, the existing Chinese patent with the publication number CN116061980A discloses a rail vehicle and roof equipment connecting device, installation and dismounting method. On the basis of ensuring that the strength of the equipment mounting seat can meet the running conditions of the vehicle, a long L-shaped hole is arranged on the side surface of the equipment lifting lug to ensure that the bolt can slide into the long hole, and a notch is arranged between the process holes and the sliding groove of the vehicle body to ensure that the equipment mounting bolt can slide into the end part of the sliding groove, so that the installation and dismounting process no longer depends on the lifting equipment tool, and the installation and dismounting of the roof equipment can be realized, and the operation is convenient.
