[0002] Asynchronous motors are one of the most widely used and most in-demand types of motors. About 90% of electrically powered mechanical equipment worldwide uses asynchronous motors, of which small asynchronous motors account for more than 70%. However, there are many inconveniences in the maintenance of small asynchronous motors, such as heavy equipment, inconvenient movement, and difficulty in adjusting angles, which increases the workload of staff. Traditional maintenance platforms cannot adjust the height of the placement table according to the user's height and operating habits, nor can they arbitrarily adjust the angle of the equipment to be repaired.

[0037] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0039] Example 1

[0040] Reference Figures 1 to 5 , is the first embodiment of the utility model, which provides a rotating mechanism, which includes,

[0041] The rotating unit 100 includes a transmission assembly 101, a bearing assembly 102 disposed on one side of the transmission assembly 101, and a locking assembly 103 disposed inside the bearing assembly 102;

[0042] The transmission assembly 101 includes a transmission shaft 101a and a hand wheel 101b disposed at one end of the transmission shaft 101a;

[0043] The hand wheel 101b includes a slide groove 101b-1 formed on the hand wheel 101b, and a handle 101b-2 movably connected to one end of the hand wheel 101b;

[0044] Among them, another group of slide grooves 101b-1 are symmetrically arranged.

[0045] Specifically, the transmission shaft 101a includes a shaft body 101a-1, a first bevel gear 101a-2 fixedly connected to one end of the shaft body 101a-1, a limiting ring 101a-3 movably engaged with the bottom of the first bevel gear 101a-2, a limiting boss 101a-4 arranged on the outer surface of the shaft body 101a-1, a sliding bar 101a-5 opened on the outer surface of the shaft body 101a-1, and a plug 101a-6 fixedly connected to one end of the shaft body 101a-1.

[0046] There are two groups of sliding bars 101a-5 symmetrically arranged.

[0047] Furthermore, the slide bar 101a-5 is movably matched with the slide groove 101b-1, and the rotating hand wheel 101b can drive the shaft body 101a-1 fixedly connected to the slide bar 101a-5 to rotate through the slide groove 101b-1.

[0048] More preferably, the bearing assembly 102 includes a second bevel gear 102a matched with the first bevel gear 101a-2, a tray 102b fixedly connected to one end of the second bevel gear 102a, a placement table 102c movably connected to the bottom of the second bevel gear 102a, and a cavity 102d opened inside the placement table 102c;

[0049] Two sets of threaded holes are symmetrically opened at both ends of the placement platform 102c.

[0050] When in use, the asynchronous motor is placed on the tray 102b. At this time, the handle 101b-2 is turned to rotate the handwheel 101b, and the slide groove 101b-1 opened by the handwheel drives the matching slide bar 101a-5 to rotate, and then drives the rotating shaft 101a fixedly connected to the slide bar 101a-5 to rotate, so that the first bevel gear 101a-2 drives the second bevel gear 102a to rotate, and then drives the tray 102b fixedly connected to it to rotate through the second bevel gear 102a.

[0051] In summary, by rotating the handle 101b - 2, the asynchronous motor placed on the tray 102b can be easily rotated to a suitable angle, which is simple and convenient.

[0052] Example 2

[0053] Reference Figures 2~5 , which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment provides a locking assembly 103 which includes a chassis 103a movably placed at one end of the hand wheel 101b, a connecting rod 103b fixedly connected to the outer surface of the chassis 103a, a guide block 103c fixedly connected to the inside of the bearing assembly 102, and a return spring 103d arranged at one end of the chassis 103a.

[0054] Specifically, the connecting rod 103b can be slidably embedded in the teeth of the first bevel gear 101a-2.

[0055] Furthermore, preferably, the reset spring 103d can use elastic force to reset the chassis 103a and the hand wheel 101b.

[0056] When in use, the hand wheel 101b is pushed forward to displace the connecting rod 103b installed on the chassis 102b, and then the connecting rod 103b touches the guide block 103c, so that the connecting rod will only displace to the outside of the first bevel gear 101a-2 to complete the unlocking. At this time, the handle 101b-2 can be turned to rotate the tray 102b. When the angle adjustment is completed, just release the hand wheel 101b, and the reset spring 103d will reset the connecting rod 103b through the chassis 103a, so that the connecting rod 103b is embedded in the teeth of the first bevel gear 101a-2, thereby automatically locking the first bevel gear 101a-2 and preventing the tray 102b from rotating.

[0057] In summary, when the tray 102b needs to be rotated to adjust the angle, the hand wheel 101b only needs to be pushed forward to unlock and rotate. When the angle of the tray 102b is adjusted appropriately, the bevel gear can be locked by simply releasing the hand wheel 101b to complete the fixed angle.

[0058] Example 3

[0059] Reference Figure 6 , which is the third embodiment of the utility model. Different from the previous embodiment, this embodiment provides an asynchronous motor maintenance platform.

[0061] Furthermore, the platform base 201 includes a base 201a, a support leg 201b fixedly connected to the bottom of the base 201a, and a guide baffle 201c fixedly installed above the base 201a;

[0062] The guide baffle 201c is movably matched with the placement platform 102c.

[0063] More preferably, the lifting assembly 202 includes a third bevel gear 202a installed inside the base 201a, a fourth bevel gear 202b matched with the third bevel gear 202a, a transmission rod 202c fixedly connected to the fourth bevel gear 202b, a lifting screw 202d fixedly connected to one end of the third bevel gear 202a, and a brake motor 202e arranged at one end of the transmission rod 202c;

[0064] The third bevel gear 202a, the fourth bevel gear 202b and the lifting screw 202d are symmetrically arranged in the same group, and the lifting screw 202d is threadedly matched with the threaded hole provided on the placement table 102c.

[0065] Furthermore, the lighting assembly 203 includes a bracket 203a fixedly mounted on the bearing assembly 102, and a lamp 203b disposed at one end of the bracket 203a.

[0066] When in use, the tray 102b is lowered to the lowest height through the lifting assembly 202, and then the asynchronous motor is moved to the tray 102b, and then the brake motor 202e is turned on to rotate the transmission rod 202c, driving the third bevel gear 202a and the fourth bevel gear 202b to rotate, so that the lifting screw 202d rotates, and then drives the placement table 102c threaded with it to move upward, and then the guide baffle 201 and the movable placement table 102c are accurately moved up and down to adjust this position that suits the height of the operator and is convenient for maintenance, and the lighting assembly is turned on, so that the asynchronous motor can be repaired in a more comfortable environment.

[0067] In summary, by turning on the brake motor, the tray 102b is lowered to facilitate the placement of the asynchronous motor on the tray 102b, and then the height of the tray 102b is adjusted by the brake motor to a height suitable for the operator to inspect, and the lighting component is turned on, so that the asynchronous motor can be inspected in a more comfortable environment.
