[0017] like Figure 1 As shown, this utility model eliminates the need for manual tightening and disassembly of the lifting lug bracket. Lifting operations are achieved through the self-weight of the drive motor body and the C-shaped structure design of the lifting lug body, along with the limiting position of the screw rubber base on the motor bracket. Multiple anti-derailment measures are implemented through the protrusions and anti-derailment bars on the lifting device body. Operation is simple, convenient, and quick, effectively reducing manual tightening time and thread damage. This invention provides a drive motor assembly lifting device, including: First hanging lug 1, as shown Figure 2 and Figure 3 As shown, the support for connecting one side of the drive motor assembly 2 includes a first support plane 3, a limiting protrusion 4 at the end of the first support plane 3, and a lifting ring 5 above the first support plane 3. During hoisting, the first support plane 3 is used to support the lower plane of the suspension bracket 6 on one side of the drive motor assembly 2, and the limiting protrusion 4 is used to limit the side of the suspension bracket 6. The lifting ring 5 is used to connect the first lifting chain 7. Second hanging lug 8, as Figure 1 , Figure 4-6 As shown, the second support plane 9 is used to connect to the other side of the drive motor assembly 2. The second support plane 9 has a flat slot 12. A hanging plate 10 is connected to the second support plane 9. The hanging plate 10 is used to connect to the second lifting chain 11. During hoisting, the second support plane 9 is connected to the lower plane of the suspension bracket 6 on the other side of the drive motor assembly 2. The protrusion of the lower plane of the suspension bracket 6 on the other side is locked in the flat slot 12.

[0018] In some embodiments, such as Figure 2 As shown, a vertical connecting part 17 is provided on the first supporting plane 3, and a hanging arm 13 is provided on the vertical connecting part 17. The lifting ring 5 is provided on the hanging arm 13. The first supporting plane 3, the vertical connecting part 17 and the hanging arm 13 enclose and form an open hanging space.

[0019] In some embodiments, such as Figure 3 As shown, an anti-detachment stop bar 14 is hinged to the hanging arm 13. The anti-detachment stop bar 14 can be rotated along the vertical hanging plane. The lower end of the anti-detachment stop bar 14 can be in contact with the limiting protrusion 4.

[0020] Furthermore, such as Figure 2As shown, the hanging arm 13 is provided with a stop bar limiting bar 15, which is located on one side of the hinge position of the anti-detachment stop bar 14. The anti-detachment stop bar 14 is provided with an anti-detachment stop bar reset device 19. The anti-detachment stop bar 14 can rotate up and down to facilitate the drive motor assembly 2 to enter the first lifting lug 1. The stop bar limiting bar 15 restricts the rotation radius of the anti-detachment stop bar 14 to prevent the drive motor assembly 2 from slipping out of the first lifting lug 1 during hoisting.

[0021] In some embodiments, such as Figure 2 As shown, a flexible pad 18 is provided on the first support plane 3.

[0022] In some embodiments, such as Figure 4-6 As shown, a hanging groove 20 is provided on the hanging plate 10, which is used to connect the second hanging chain 11.

[0023] In some embodiments, such as Figure 6 As shown, the second support plane 9 has a side opening that connects to the plane slot 12.

[0024] In some embodiments, such as Figure 2 As shown, the limiting protrusion 4 is characterized by having a guide slope.

[0025] In some embodiments, the second lug 8 and the hanging plate 10 have an angle of no more than 90°.

[0026] Furthermore, such as Figure 2 and Figure 3 As shown, the anti-detachment lever 14 reset device includes a torsion spring 16 on the hinge shaft of the anti-detachment lever 14. One end of the torsion spring 16 is engaged with the anti-detachment lever 14, and the other end is engaged with the stop bar limit bar 15. When the anti-detachment lever 14 is released, the torsion spring 16 pulls the bottom end of the anti-detachment lever 14 to the bottom of the first lifting lug 1, and automatically returns to its original position to achieve the locking purpose.

[0027] like Figure 1As shown, in use, the anti-slip lever 15 is lifted, and the first lifting lug 1 and the second lifting lug 8 are respectively fitted onto both sides of the suspension bracket 6 of the drive motor assembly 2. The flexible pad 18 limits and locks the drive motor assembly 2. The limiting protrusion 4 on the side of the first lifting lug 1 blocks the suspension bracket 6 to prevent the drive motor assembly 2 from swinging, thus achieving a primary anti-slip effect. The torsion spring 16 pulls down the support leg of the anti-slip lever 15 and engages with the first lifting lug 1, preventing the anti-slip lever 15 from swinging, thus achieving a secondary anti-slip function. The first lifting lug 1 is connected to the electric hoist via the first lifting chain 7 on the lifting ring 5 and the second lifting lug 8 via the second lifting chain 11. When the electric hoist is started, the electric hoist lifts the first lifting lug 1 and the second lifting lug 8 on both sides of the drive motor assembly 2 to the designated working position via the first lifting chain 7 and the second lifting chain 11. Subsequently, the first lifting chain 7 is lowered and disengaged from the lifting ring 5. Then, the anti-derailment lever 15 is rotated so that the support leg at the bottom of the anti-derailment lever 15 is disengaged from the bottom of the first lifting lug 1. The first lifting lug 1 is then removed, completing the quick disassembly.
