Description

Technical Field

[0001] This utility model relates to the field of crane winch technology, specifically to a modular structure for a crane winch. Background Technology

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

[0003] The winch structure of a crane includes a motor mechanism and a drum mechanism. In the existing technology, the motor mechanism and the drum mechanism are supported by different support mechanisms and fixed together. This split structure makes the winch structure unstable during hoisting. Moreover, during hoisting, the motor mechanism and the drum mechanism need to be lifted separately with wire ropes. The lifting force on both sides must be balanced, otherwise it is easy to cause tilting, resulting in poor safety and low hoisting efficiency. Utility Model Content

The auxiliary pad and the second roll frame pad are respectively provided at both ends of the second roll frame support plate. The second roll frame support plate and the auxiliary pad are connected and fixed to the bottom of the mounting bracket of the motor mechanism.

[0010] The end of the intermediate housing away from the bearing seat support plate is integrally connected to a motor mounting bracket support plate. The motor mounting bracket support plates are connected and fixed together by stiffeners. A motor mounting bracket pad is fixed to the top of the motor mounting bracket support plate. The motor mounting bracket support plate, the motor mounting bracket pad, and the bottom of the motor mechanism mounting bracket are connected and fixed together.

[0011] Furthermore, the bearing seat pad is located on the side of the intermediate housing.
