[0002] When replacing the motor of a battery locomotive for open-pit mines, since the motor is connected to the wheel set, the motor and the wheel set need to be disassembled and installed together when replacing the motor. However, it is difficult to fix the position of the wheel set. If there is a deviation between the installation position and the disassembly position, the installation cannot be completed. Therefore, it is often necessary to manually measure the distance from the hanging ear of the main motor cross arm to the cement wall of the trench, and repeatedly try to hoist it to the original position during installation, resulting in increased labor intensity of maintenance personnel and longer maintenance time. Summary of the Invention

[0003] Aiming at the deficiencies existing in the prior art, the purpose of the utility model is to provide a positioning device for replacing a motor of a battery locomotive for open-pit mines, and solve the technical problems of difficult accurate positioning of the wheel set and high labor intensity when replacing the motor of a battery locomotive for open-pit mines in the prior art.

[0005] A positioning device for replacing a motor of a battery locomotive for open-pit mines, including a rail fixing clamp with an open bottom, and the top of the rail fixing clamp is fixedly connected to the bottom of the wheel set support seat.

[0006] The wheel set support seat is provided with a wheel set fitting positioning arc-shaped opening.

[0007] The wheel set fitting positioning arc-shaped opening can fit with the outer edge of the wheel set of the battery locomotive.

[0008] The utility model also has the following technical features:

[0009] The inside of the rail fixing clamp is a slot open at both ends and the bottom. A plurality of threaded holes are respectively and uniformly arranged on the two side walls of the rail fixing clamp. Each threaded hole penetrates through the side wall of the rail fixing clamp, and a fixing screw is respectively installed in each threaded hole.

[0010] Compared with the prior art, the utility model has the following beneficial technical effects:

[0011] (Ⅰ) According to the principle of mechanical dynamics and the characteristics of the wheel set and motor of a battery locomotive for open-pit mines, the device of the utility model designs a special technology for solving the problem of difficult accurate positioning when replacing the motor of a battery locomotive for open-pit mines, can efficiently replace the motor, and avoid the adverse effects of increased labor intensity of maintenance personnel and low maintenance efficiency caused by the inability to accurately determine the positions of the wheel set and the motor.
