Description

Technical Field

[0001] The utility model relates to the technical field of motor equipment, and in particular to a motor load maintenance rotary device. Background Art

[0002] Motors are a commonly used equipment and are very common in factories. Motors are usually equipped with loads. When the load needs to be inspected and maintained, the motor cannot be started directly. Instead, the motor needs to be turned manually to make the load move little by little. For example, when inspecting the elevator, each time the elevator is inspected, it is necessary to turn the fan blades of the motor to turn the elevator. Due to the small contact area of ​​the fan blades, it is very laborious to turn them. At least two people are required each time to turn them, and it is also very easy to break the fan blades. Broken fan blades during turning will cause reversal, and there is also a safety hazard.

[0003] After searching, China disclosed a motor load maintenance rotating device with patent publication number CN213341807U on June 1, 2021. It is roughly described as including a motor body with a mounting seat, and the part of the motor body's rotating shaft extending out of the motor body is provided with a keyway; a first sleeve cooperating with the keyway is sleeved on the rotating shaft, and a connecting rod for convenient rotation is connected to the sleeve. The motor load maintenance rotating device of the utility model, through the motor body, rotating shaft, keyway, first sleeve and connecting rod, when performing maintenance, the fan blades are removed first after power is turned off, and then the first sleeve is sleeved on the rotating shaft and cooperates with the keyway. At this time, the connecting rod is rotated according to the needs of the maintenance situation, so that the load moves slowly for maintenance. It has the characteristics of simple structure and convenient maintenance of the motor load.

[0004] Although the above-mentioned prior art solution avoids breaking of the fan blades and reduces safety hazards, the device needs to tighten three locking screws separately when connecting the first sleeve and the rotating shaft, which is troublesome and reduces work efficiency.
