[0002] The underbody parts of a train based on a rail bridge are usually large equipment, including air conditioners, water tanks, ventilation devices, brakes, waste boxes, main air compressors, auxiliary air compressors and other equipment. These equipment need to be disassembled and repaired regularly. When installing these accessories, a positioning device is needed to align the equipment with the installation position so that they can be accurately installed. At present, the equipment is basically moved by manpower for positioning. The authorization announcement number CN215942014U discloses a positioning device for disassembling and assembling underbody parts of a train, including a fixed platform, a first drive assembly, a second drive assembly and an alignment platform. The first drive assembly and the two second drive assemblies are all fixed on the fixed platform, and the output directions are respectively along the X-axis and Y-axis directions; this device can accurately align, but this device is not convenient to move, and the device cannot be automatically lifted, so that after the alignment is completed, manpower is still needed to send the device to the installation position, which is more laborious, and this device lacks a fixing mechanism, which leads to the easy movement of the device when aligning the device, affecting the alignment efficiency. For this reason, we propose a positioning device for disassembling and assembling underbody parts of a train. Utility Model Content
