Description

Technical Field

[0001] The present application relates to the technical field of winches, and in particular to a power transmission mechanism for winch maintenance. Background Art

[0002] A winch, also known as a hoist, is a lifting device that uses a drum to wind a wire rope or chain to lift or pull heavy objects. A winch can lift vertically, pull horizontally or tilt heavy objects. It can be used alone or as a component of machinery such as lifting, road construction and mine hoisting. It is widely used due to its simple operation, large rope winding capacity and convenient relocation. It is mainly used for lifting or flat towing materials in construction, water conservancy projects, forestry, mining, docks, etc.

[0003] Large-tonnage winches are mainly used for hoisting and unloading heavy objects. After long-term use, the motor connecting shaft of the winch is prone to wear and other damages. The damaged motor connecting shaft needs to be repaired. During the repair, an additional power device is required to drive the motor connecting shaft to rotate. However, it is difficult to align the axis of the output shaft of the existing power device with the axis of the motor connecting shaft, which reduces the repair efficiency, so further improvement is needed. Utility Model Content
