Description

Technical Field

[0001] The utility model relates to the relevant field of heavy-load rotation auxiliary detection technology, in particular to an electric turning auxiliary device. Background Art

[0002] Cranking means turning the motor a few times by manpower before starting it, in order to determine whether the load driven by the motor (i.e. the mechanical or transmission part) is stuck and the resistance is increased, so as to avoid the situation where the starting load of the motor is too large and damages the motor. Generally, cranking is required when the motor is started again after the equipment has been shut down for 8 hours. Chemical and mining companies have large and heavy-loaded rotating equipment such as large compressors and crushers. The traditional forms of cranking are all manual cranking.

[0003] The Chinese patent document with publication number CN204154758U discloses an electric winch device, which starts a reducer to reduce the speed and then drives the transfer motor of the heavy-load equipment to rotate slowly through a rotating connecting tube. At this time, the user can observe and judge whether the transfer motor is running normally, thereby achieving the purpose of winch detection;

[0004] When the reducer in the original equipment is used for a long time, the reducer parts will inevitably age due to being exposed to the outside for a long time, which will cause noise pollution. The staff working in a long-term noise pollution working environment will inevitably bring health risks to the staff, and thus need to be improved on the original basis. Utility Model Content
