Description

Technical Field

[0001] The utility model belongs to the technical field of electromechanical equipment detection, and more specifically, particularly relates to a safety maintenance device. Background Art

[0002] During the operation of electromechanical equipment, it is often necessary to use motors and other driving machines to provide power. Therefore, a group of equipment may be installed with multiple motors as power sources. Long-term operation may cause transmission deviations due to factors such as vibration, which will gradually cause the speed to decrease and the rotation to be uneven. Therefore, regular inspections are required to avoid failures of the motor's transmission parts, such as belt and chain breakage, gear deformation, etc., which affect work safety.

[0003] Based on the above, the current practical maintenance method is mainly monitored by sensors of the machine body, and the sensors only monitor the driven shaft, which is inconvenient to select and detect the motor and other transmission components. It has poor adaptability and lacks highly applicable installation functions and convenient control installation structures. Utility Model Content
