[0002] Bridge cranes are mainly used for lifting various materials and are generally placed on the top of production workshops and warehouses. Bridge cranes are powered by busbar devices, which are mainly composed of busbar rails, current collectors, fixed brackets and other components. Among them, there are 4 busbar rails, namely A, B, C phase lines and ground wires. The busbar rails are in a fixed state, and the current collector contacts the busbar rails to obtain power. It will continue to move with the operation of the bridge crane, generating friction and transmitting vibration. With the long-term operation of the bridge crane, the contact state between the busbar and the current collector will change, resulting in poor contact or even falling off, which will cause safety hazards, reduce the stability of the busbar system, and affect the daily production of the factory. Therefore, it is particularly important to monitor the contact state of the busbar and perform maintenance after the problem is found. Since the power supply system of the bridge crane is generally placed on the top of the production workshop, its fixed bracket often has problems such as insufficient stability, inconvenient maintenance, and no monitoring function.
