Technical Field
[0001] This utility model relates to the technical field of fan turning gear devices, specifically an automatic fan turning gear device. Background Technology
[0002] During operation, existing fans may experience thermal deformation, uneven lubrication, or adhesion of bearings, rotors, and related components due to prolonged shutdown. Therefore, a turning device is needed to periodically rotate the fan shaft slowly to prevent the fan shaft from bending or experiencing excessive local stress.
[0003] Traditional turning gear systems mostly employ either manual or electric turning methods, which lack flexibility in use. When the electric turning gear malfunctions or requires maintenance, it is often impossible to switch to manual turning in a timely manner, leading to interruptions in the fan turning operation and affecting the safe operation of the equipment. In addition, some systems have fixed gear meshing structures, which cannot achieve rapid disengagement and re-engagement as needed, resulting in insufficient adaptability and operational inconvenience.
[0004] Therefore, it is necessary to design an automatic fan turning device to solve the above problems. Utility Model Content

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0016] Please see Figure 1-4This utility model provides an automatic fan turning device, including an equipment box 1. An equipment housing 3 is fixedly connected to one side of the equipment box 1, and a connector box 6 is movably inserted into one side of the equipment housing 3.

[0020] To facilitate the sliding engagement of the fourth gear 17 and the third gear 16, and to facilitate the threaded connection between the equipment box 3 and the plug-in box 6, the top of the equipment box 1 is threadedly connected to the top of the top cover 2, and the top of the plug-in box 6 is threadedly connected to the top of the top cover 2 by bolts, and one end of the connecting plate 7 is threadedly connected to the top of the equipment box 3 by bolts.
[0021] In order to amplify the output torque and reduce the effort required when manually turning the gear, and at the same time, in order to obtain sufficient torque on the fan shaft when automatically turning the gear, the gear ratio of the fourth gear 17 and the third gear 16 is 3:1, the gear ratio of the first gear 8 and the second gear 9 is 3:1, and the fourth gear 17 is rotatably connected to the inside of the U-shaped opening of the U-shaped block 19.
