[0033] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of an auxiliary device for mounting a motor according to the present invention in conjunction with the accompanying drawings.

[0034] like Figures 1 to 10 As shown, a motor installation auxiliary device includes a traction mechanism, a lifting bracket and a shaft sleeve group. When repairing the motor, the motor end cover is assisted in lifting; when installing the motor end cover, the height of the motor rotor main shaft is centered and adjusted.

[0035] The traction mechanism includes a saddle bracket 1, the lower portion of which features an arc-shaped design to fit snugly against the outer wall of the motor. A bracket fixing bolt 11 is provided at the lower portion of the saddle bracket 1. These bolts are T-shaped double-ear bolts, making it easy for workers to tighten these bolts to secure the saddle bracket 1 to the motor. A winding drum 13 is located above the saddle bracket 13, with a second gear 15 located on one side of the drum. This second gear 15 controls the rotation of the drum 13. A first gear 14 engages above the second gear 15, and a crank 12 is located on one side of the first gear 14. This crank 12 controls the rotation of the first gear 14, further controlling the rotation of the drum 13. The first gear 14 is smaller than the second gear 15. A lock 16 is located in front of the second gear 15 to prevent it from tilting and injuring workers when the motor end cover is hoisted. A traction rope 17, made of oil-lined rope, is wound around the drum 13.

[0036] The hanging bracket includes a first curved support rod 2 and a second curved support rod 3 that are hinged together. The curved end of the first curved support rod 2 is provided with a hinge hole 21, and the curved end of the second curved support rod 3 is provided with a hinge rod 22. The hinge hole 21 is an elongated oval, and the hinge rod 22 can move back and forth on the hinge hole 21. Round tubes 63 are provided on the horizontal rods of the first curved support rod 2 and the second curved support rod 3. The round tubes 63 are provided with fixing belt buckles 64. The fixing belt buckles 64 are provided with fixing belts 4. The fixing belts 4 are capable of connecting the two fixing belt buckles 64 together. The first and second arc-shaped support rods 2 and 3 are each vertically and movably connected to a support rod 5 on the horizontal rod. The other end of the support rod 5 is vertically connected to a cross bar 6. There are two support rods 5. Both ends of the support rods 5 are provided with a sleeve 61 that is sleeved on the first and second arc-shaped support rods 2, 3, and cross bar 6. The sleeve 61 is provided with a sleeve fixing bolt 62. The sleeve fixing bolt 62 is a T-shaped double-ear bolt that can fix the position of the sleeve 61. The sleeve 61 connected to the first and second arc-shaped support rods 2 and 3 is arranged on the outside of the circular tube 63. The traction rope 17 is connected to the middle position of the cross bar 6.

[0037] The shaft sleeve assembly includes a shaft sleeve 7, and hooks 71 are provided on both sides of the shaft sleeve 7. The hooks 71 can be used to easily lift accessories and tools such as the motor end cover and the hydraulic puller. A wire-releasing bracket 72 is provided above the shaft sleeve 7, and a winding wheel 73 is provided inside the wire-releasing bracket 72. Two strands of lifting rope 75 are wound inside the winding wheel 73. The lifting rope 75 is an oil-wire rope. A locking bolt 74 for braking the winding wheel 73 is provided on the outside of the wire-releasing bracket 72. The locking bolt 74 is a T-shaped double-ear bolt. A through hole is provided at the center position above the wire-releasing bracket 72. The two strands of the lifting rope 75 pass through the through hole on the wire-releasing bracket 72 and are respectively connected to the left and right sides of the cross bar 6. The connection between the lifting rope 75 and the cross bar 6 is located between the left and right sleeves 61.

[0038] When the present invention is in use, the staff first places the first arc-shaped support rod 2 and the second arc-shaped support rod 3 under the motor 8, adjusts the positional relationship between the hinge hole 21 and the hinge rod 22, so that the first arc-shaped support rod 2 and the second arc-shaped support rod 3 fit under the motor 8, and then passes the fixing belt 4 through the fixing belt lock 64 on the first arc-shaped support rod 2 so that the fixing belt 4 fits above the motor 8. At this time, the hanging bracket is firmly fixed to the outer wall of the motor 8. Then, the saddle bracket 1 is placed in a suitable position above the motor 8, and the bracket fixing bolts 11 are tightened to fix the saddle bracket 1 above the motor 8. Then, the motor end cover is passed through the motor rotor, the shaft sleeve 7 is put on the motor rotor, and the hook 71 on the shaft sleeve 7 lifts the motor end cover. The staff loosens the locking bolt 74, adjusts the lifting rope 75 to an appropriate length, then tightens the locking bolt 74, loosens the lock buckle 16, and turns the crank 12 to raise the motor rotor to an appropriate position for centering adjustment. After the motor rotor position adjustment is completed, the lock buckle 16 is locked. At this time, the staff can quickly install the motor end cover to the main body of the motor 8.
