[0028] Example 1

[0029] like Figure 1 to Figure 4 As shown, the tooling for installing the motor rotor on the construction site of the utility model comprises a hanger 1, the hanger 1 comprises a horizontal beam 11 and a vertical beam 12, one end of the horizontal beam 11 and one end of the vertical beam 12 are connected to form a whole; a fixed cylinder 13 is fixed at the lower end of the vertical beam 12, a rolling-matching lifting sleeve 2 is installed on the horizontal beam 11, and the lifting sleeve 2 comprises at least a lifting portion 21 for fitting a lifting rope;

[0030] Matching leveling mechanisms 3 are installed on the crossbeam 11 and the lifting sleeve 2 , and the leveling mechanisms 3 are used to adjust the relative position of the lifting sleeve 2 and the crossbeam 11 .

[0031] The leveling mechanism 3 includes a screw rod that drives the hoisting sleeve 2 to move back and forth, one end of the screw rod is connected to a driving motor 32, and the driving motor 32 can be a servo motor, and also includes a guide rod 33 used in conjunction with the screw rod, the guide rod 33 slides to cooperate with the hoisting sleeve 2, and both sides of the guide rod 33 are fixed to the crossbeam 11;

[0032] A level sensor 31 for controlling a driving motor 32 is also installed on one side of the crossbeam 11 .

[0033] A roller 23 is disposed inside the lifting sleeve 2 and cooperates with the upper surface of the crossbeam 11 .

[0034] The rollers 23 can be arranged correspondingly up and down inside the lifting sleeve 2.

[0035] A lifting portion 21 is provided in the middle of the lifting sleeve 2. The lifting portion 21 is a sleeve with a square cross section, and baffles 22 are provided on both sides of the sleeve.
