Description

Technical Field

[0001] The utility model relates to the field of motor processing. More specifically, the utility model relates to a hoisting tooling for a motor rotor. Background Art

[0002] During the processing of medium and large-sized motors, it is necessary to hoist and transfer the motor rotor. Currently, the relatively common hoisting method is to use a hoisting belt to hold both ends of the motor rotor shaft, or to use a C-shaped lifting tool for hoisting.

[0003] For example, a utility model patent with the authorization announcement number CN 207664841 U discloses a rotor hoisting fixture. A positioning seat is arranged at the lower end of the lifting arm. One end of the motor rotor shaft is fixed through the positioning seat to fix the motor rotor and the lifting arm, and then the lifting arm is hoisted by a crane. When the above-mentioned hoisting fixture is hoisted, it can only fix one end of the motor rotor shaft. For a motor rotor with a relatively small weight, the connection stability between the motor rotor and the lifting arm can be ensured during the hoisting process. However, when hoisting a motor rotor with a particularly large weight, since only one end of the motor rotor shaft is fixed, there is a risk of disconnection between the motor rotor and the lifting arm at this time. During the hoisting process, the positioning seat may be disengaged from the motor rotor. Due to the particularly large mass of the motor rotor, the consequences after disconnection are unimaginable. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a hoisting tooling for a motor rotor, which fixes both ends of the motor rotor to ensure the connection stability with the motor rotor during hoisting.

[0005] The technical solution for the utility model to solve the above technical problems is as follows: A hoisting tooling for a motor rotor includes:

[0006] A hoisting rod, with a lifting ring provided at its upper end;

[0007] A fixed clamping mechanism, which is used to fix one end of the motor rotor shaft and is fixedly arranged at the lower end of the hoisting rod;

[0008] A movable clamping mechanism, which is used to fix the other end of the motor rotor shaft. The movable clamping mechanism is slidably connected to the hoisting rod and can be connected and fixed to the hoisting rod at any position on its sliding track.

[0009] Further, in the hoisting tooling for a motor rotor, the fixed clamping mechanism includes:

[0010] A first connecting rod, whose upper end is connected to the hoisting rod and whose lower end is connected with a clamping assembly.

[0011] Further, in the motor rotor hoisting tooling, the moving clamping mechanism includes:

[0012] A slider, which is slidably connected to the hoisting rod and can be fixedly connected to the hoisting rod at any position on its sliding trajectory;

[0013] A second connecting rod, the upper end of which is connected to the slider, and the lower end of which is connected with a clamping assembly.

[0014] Further, in the motor rotor hoisting tooling, a first through groove corresponding to the hoisting rod is provided on the slider, the hoisting rod passes through the first through groove and is slidably connected to the slider, and a plurality of first threaded through holes are provided on the slider at intervals, and a first bolt is threadedly installed in the first threaded through hole.

[0015] Further, in the motor rotor hoisting tooling, the clamping assembly includes:

[0016] A first cylinder body;

[0017] A second cylinder body, which is coaxially and fixedly arranged in the middle of the inner side of the first cylinder body. A plurality of notches are evenly distributed along the circumference of the second cylinder body. A clamping block is arranged in the notch. A second threaded through hole corresponding to the notch is provided on the first cylinder body, and a second bolt is threadedly installed in the second threaded through hole. The second bolt is rotatably connected to the clamping block;

[0018] Two third cylinder bodies, which are detachably coaxially arranged in the first cylinder body and are respectively located on both sides of the second cylinder body.

[0019] Further, in the motor rotor hoisting tooling, a plurality of positioning holes are evenly distributed along the circumference of the third cylinder body. A third threaded through hole corresponding to the positioning hole is provided on the first cylinder body, and a third bolt is threadedly installed in the third threaded through hole. When the third cylinder body is connected to the first cylinder body, the third bolt extends into the positioning hole.

[0020] The beneficial effects of the present utility model are:

[0021] 1. In the motor rotor hoisting tooling of the present utility model, both ends of the motor rotor are fixed respectively by the fixed clamping mechanism and the moving clamping mechanism, ensuring the connection stability with the motor rotor during the hoisting process;

[0022] 2. In the motor rotor hoisting tooling of the present utility model, the position of the moving clamping mechanism can be adjusted relative to the fixed clamping mechanism, and can be adjusted according to the length of the motor rotor shaft. At the same time, both third cylinder bodies are detachable and can be replaced according to the diameter of the motor rotor shaft, so that the motor rotor hoisting tooling of the present utility model can be applied to the hoisting of motor rotors of various different sizes.

[0028] Figure 1 A motor rotor hoisting tooling provided by an embodiment of the present utility model includes:

[0029] A hoisting rod 1, with a lifting ring 2 provided at its upper end;

[0030] A fixed clamping mechanism, which is used to fix one end of the motor rotor shaft and is fixedly arranged at the lower end of the hoisting rod 1;

[0031] Among them, the fixed clamping mechanism includes:

[0032] A first connecting rod 3, whose upper end is connected to the hoisting rod 1 and whose lower end is connected to a clamping assembly 4;

[0033] A movable clamping mechanism, which is used to fix the other end of the motor rotor shaft. The movable clamping mechanism is slidably connected to the hoisting rod 1 and can be connected and fixed to the hoisting rod 1 at any position on its sliding trajectory;

[0034] Among them, the movable clamping mechanism includes:

[0035] A slider 5, which is slidably connected to the hoisting rod 1 and can be fixedly connected to the hoisting rod 1 at any position on its sliding track. A first through groove corresponding to the hoisting rod 1 is provided on the slider 5. The hoisting rod 1 passes through the first through groove and is slidably connected to the slider 5. A plurality of first threaded through holes are provided on the slider 5 at intervals, and a first bolt 7 is threadedly installed in the first threaded through hole.

[0036] A second connecting rod 6, whose upper end is connected to the slider 5 and whose lower end is connected with a clamping assembly 4.

[0037] In this embodiment, the lifting ring 2 of the hoisting rod 1 is connected to the hoisting equipment. When using the motor rotor hoisting tooling, move the initial position of the clamping mechanism as far away from the fixed clamping mechanism as possible, which is convenient for hoisting the hoisting rod 1 above the motor rotor and slowly lowering it, so that the two clamping assemblies 4 of the fixed clamping mechanism and the moving clamping mechanism are respectively located on both sides of the motor rotor. Then horizontally move the hoisting rod 1 so that one end of the motor rotor shaft is connected to the clamping assembly 4 on the fixed clamping mechanism. Then slide the slider 5 towards the fixed clamping mechanism so that the clamping assembly 4 on the fixed clamping mechanism is connected to the other end of the motor rotor shaft. Tighten the plurality of first bolts 7 on the slider 5 to fix the slider 5 to the hoisting rod 1, that is, complete the fixation of the moving clamping mechanism. At this time, both ends of the motor rotor shaft are connected and fixed to the motor rotor hoisting tooling, and then the hoisting of the motor rotor can be carried out.

[0038] Preferably, as another embodiment of the present invention, as Figure 2 shown, the clamping assembly 4 includes:

[0039] A first cylinder body 8, the middle part of whose upper end is connected to the first connecting rod 3 or the second connecting rod 6;

[0040] A second cylinder body 9, which is coaxially and fixedly arranged in the middle of the inner side of the first cylinder body 8. A plurality of notches 10 are evenly distributed along the circumferential direction on the second cylinder body 9. A clamping block 11 is arranged in the notch 10. A second threaded through hole corresponding to the notch 10 is provided on the first cylinder body 8, and a second bolt 12 is threadedly installed in the second threaded through hole. The second bolt 12 is rotatably connected to the clamping block 11; a bearing can be used to connect the second bolt 12 and the clamping block 11.

[0041] Two third cylinder bodies 13, which are detachably coaxially arranged in the first cylinder body 8 and are respectively located on both sides of the second cylinder body 9. A plurality of positioning holes 14 are evenly distributed along the circumferential direction on the third cylinder body 13. A third threaded through hole corresponding to the positioning hole 14 is provided on the first cylinder body 8, and a third bolt 15 is threadedly installed in the third threaded through hole. When the third cylinder body 13 is connected to the first cylinder body 8, the third bolt 15 extends into the positioning hole 14.

[0042] In this embodiment, the third cylinder 13 is detachably connected to the first cylinder 8. Multiple groups of the third cylinders 13 can be provided. According to the diameters of both ends of the rotating shaft of the motor rotor to be hoisted, the third cylinder 13 with an inner diameter equal to it is selected. After aligning the positioning holes 14 on the third cylinder 13 with the third threaded through holes on the first cylinder 8, it is coaxially placed into the first cylinder 8. The first cylinder 8 abuts against the second cylinder 9, and the second cylinder 9 is used to limit it. The third cylinder 13 is slightly rotated to make the multiple positioning holes 14 communicate with the third threaded holes one by one. Then, a third bolt 15 is threadedly installed in the third threaded through hole, and the third bolt 15 is tightened so that it extends into the positioning hole 14, and thus the connection between the third cylinder 13 and the first cylinder 8 can be completed. When fixing the rotating shaft of the motor rotor, first extend the rotating shaft of the motor rotor into the first cylinder 8, sequentially pass through the second cylinder 9 and the third cylinder 13 inside it, and then tighten the second bolt 12 on the second cylinder 9 so that the clamping block 11 abuts against the rotating shaft of the motor rotor, thereby fixing the rotating shaft of the motor rotor and the first cylinder 8 through multiple clamping blocks 11.

[0043] In this embodiment, two third cylinders 13 are provided. In actual use, only one third cylinder 13 can be installed according to the actual size of the rotating shaft of the motor rotor.
