Abstract

The invention provides a winch, and belongs to the technical field of marine machinery. The winch comprises a pneumatic clutch assembly, a transition plate, a machine base, a bearing block, a rollingbearing, a driving mechanism and a roller, wherein the roller is coaxially arranged on the driving mechanism, the driving mechanism is rotatably arranged on the machine base, the driving mechanism isused for driving the roller to rotate, the transition plate and a pneumatic clutch assembly coaxially sleeve a rotating shaft of the driving mechanism and fixedly connected with the machine base, thepneumatic clutch is configured to limit rotation of the rotating shaft of the driving mechanism when the pneumatic clutch assembly is in a first state, the rolling bearing sleeves the transition plate, the bearing block sleeves the rolling bearing, the rolling bearing and the bearing block are positioned between the transition plate and the roller, the bearing block is fixedly connected with the transition plate and the roller correspondingly, and the bearing block is formed by detachably connecting an upper semicircular bearing block and a lower semicircular bearing block. The winch is compact in structure and more convenient to disassemble and maintain.

Description

technical field [0001] The present disclosure relates to the technical field of marine machinery, in particular to a winch. Background technique [0002] A winch is a light and small lifting device that uses a drum to wind a wire rope or chain to lift or pull heavy objects, also known as a hoist. The winch can be used alone or as an integral part of machinery such as lifting, road construction and mine hoisting. It is widely used in construction, water conservancy projects, forestry, Mines, docks and other locations. [0003] The winch includes a driving mechanism, a driving shaft, a drum and a clutch. The driving mechanism drives the driving shaft to rotate. By controlling the clutch, the driving shaft and the drum are connected or separated, so that the power of the driving mechanism is transmitted to the drum through the driving shaft and the clutch. To drive the drum to rotate forward and reverse, and then make the steel wire rope wound on the drum realize the retracta...
