Here, the first matching portion can be set on the side of the motor housing where the bolts are not installed, and the second matching portion can be set on the side of the reducer housing where the bolts are not installed. The width dimension of the first support plate 21 can be set to be smaller, and it contacts the parts of the reducer housing and the motor housing where the bolts are not installed to avoid blocking the bolts. The first positioning member 3 and the second positioning member 4 are located at both ends of the first support plate 21 in the Y direction, that is, the left and right ends of the first support plate 21, and are within the visual range of the operator, making the positioning and clamping of the electric drive assembly 10 more convenient.

[0040] In some other embodiments, one first positioning post 32 and one second positioning post 42 may be provided respectively. In this case, the first positioning post 32 and the second positioning post 42 are preferably not coaxial to prevent the electric drive assembly 10 from rotating and shaking.

Part of the rotation drive device 5 can pass through the second frame 12 along the Y direction and be drivingly connected to the first support plate 21.

[0043] In this embodiment, the rotation drive device 5 provides a rotation drive force around the Y axis to drive the support plate 2 and the electric drive assembly 10 thereon to rotate around the Y axis relative to the second frame 12 to adjust the angle of the electric drive assembly 10. The first frame 11 can be used to support the second frame 12 to facilitate the movement of the frame 1 on the ground.

The first positioning plate 31 of the first positioning member 3 and the second support plate 22 can be bolted and fixed, and the second positioning plate 41 of the second positioning member 4 is slidably arranged on the first support plate 21. By providing the second support plate 22, the support plate 2 can be conveniently connected to the rotation drive device 5.

[0046] First, move the second positioning member 4 away from the first positioning member 3, then place the electric drive assembly 10 on the first support plate 21, and position and assemble the electric drive assembly 10 and the first positioning member 3, then move the second positioning member 4 toward the first positioning member 3, so as to position and assemble the second positioning member 4 and the electric drive assembly 10, and thus complete the clamping of the electric drive assembly 10 on the disassembly and repair device.

[0047] like Figure 1 As shown, optionally, one of the first support plate 21 and the second positioning member 4 is provided with a slide rail 211 , and the other of the first support plate 21 and the second positioning member 4 is provided with a slide groove matching the slide rail 211 .

[0049] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, optionally, the disassembly and repair device further includes a first limiting mechanism 6 , and the first limiting mechanism 6 is used to limit the movement of the first positioning member 3 and / or the second positioning member 4 relative to the first support plate 21 .

[0050] Since at least one of the first positioning member 3 and the second positioning member 4 is used to move relative to the first support plate 21, in this embodiment, the first limiting mechanism 6 is used to limit the movement of at least one of the first positioning member 3 and the second positioning member 4 relative to the first support plate 21, that is, when any one of the first positioning member 3 and the second positioning member 4 moves relative to the first support plate 21, the first limiting mechanism 6 is used to limit the movement of the one of the first positioning member 3 and the second positioning member 4 that can move relative to the first support plate 21; when both the first positioning member 3 and the second positioning member 4 move relative to the first support plate 21, the first limiting mechanism 6 is used to respectively limit the movement of the first positioning member 3 and the second positioning member 4 relative to the first support plate 21.

[0056] A wheel 9 is provided at each of the four corners of the first frame 11, and the frame 1 can travel by means of the wheel 9. The lifting device lifts the electric drive assembly 10 onto the first support plate 21, and after clamping it by means of the first positioning member 3 and the second positioning member 4, the repair and disassembly device can be pushed to other positions, or more precisely, pushed out of the swing range of the lifting device, so as to avoid potential safety hazards to the operators due to the lifting device moving back and forth above during disassembly.

The reducer 52 can realize the function of torque amplification. The small driving force applied to the handwheel 51 by the operator is amplified and output to the support plate 2 to drive the electric drive assembly 10 to rotate.
