[0002] A mine locomotive is a special type of electric motor vehicle used in industrial environments such as mines. It is mainly used for transporting and handling heavy items such as ores and coals, and has characteristics such as strong load-bearing capacity, adaptability to harsh environments, and high energy efficiency. Mine locomotives are usually equipped with a powerful motor system to meet the requirements of high load and long-time operation.

[0003] In a mine locomotive, the motor is one of the core components and plays a crucial role. The motor converts electrical energy into mechanical energy to drive the vehicle for operation and traction. The performance of the motor directly affects aspects such as the operation efficiency, power output, load capacity, and reliability of the locomotive. A good motor can provide sufficient torque and power, enabling the locomotive to smoothly perform various work tasks.

[0004] Due to the structural limitations of the locomotive, each time the motor is replaced, the motor suspension bolts and axle box bolts must be removed first to separate the motor from the locomotive frame. Then, a lifting device is used to lift and remove the entire locomotive frame, leaving only the motor and axle boxes for maintenance. After the maintenance is completed, the locomotive frame is lifted again for assembly. There are the following problems in the disassembly and installation process of the motor and axle boxes:

[0005] 1. Gravity imbalance: To prevent the motor and axle boxes from tipping or jamming inside the carriage due to gravity imbalance, a lifting device is needed to fix the motor.

[0006] 2. Fixing obstruction: During the process of lifting the locomotive frame, the fixing of the motor may cause obstruction and prevent it from being adjusted out.

[0007] 3. Difficulty in alignment: When installing the motor, it is very difficult to automatically align the motor with the locomotive frame. The installation process is very difficult, time-consuming, and laborious, resulting in very low maintenance efficiency.
