A winch for ship traction and hoisting

Abstract

The invention relates to the technical field of machinery, and discloses a hoist for ship traction and hoisting, comprising a reel, one end of the reel is rotatably connected with a fixed rod, and the fixed rod extends into the inner cavity of the reel and is fixedly connected with a The inner cylinder, the main electromagnet is fixedly installed inside the inner cylinder, and the side of the inner cylinder is provided with a plurality of slideways corresponding to the pole faces of the main electromagnet, and the slideways at both ends of the inner cylinder are provided with damping mechanisms , the slideway in the middle of the inner cylinder is provided with a main friction mechanism, and the inner wall of the reel is respectively provided with a baffle plate and a dynamic friction belt corresponding to the positions of the damping mechanism and the main friction mechanism. The present invention converts a part of the rotational kinetic energy of the reel into the elastic potential energy of the damping spring through the blocking of the baffle by the damping spring, thereby reducing the rotational speed of the baffle, reducing the friction loss at the moment of contact between the static friction belt and the dynamic friction belt, and prolonging the static friction belt and the dynamic friction belt. The service life of the dynamic friction belt is improved, and the maintenance cost of the hoist is also reduced.

Description

Technical field [0001] The present invention relates to the field of mechanical technology, and specifically a ship is induced by a reuse of reuse. Background technique [0002] The hoist is the simplest lifting device in the crane. It can be used alone or as the main structure of various lifting machines. Combining the hoist with the pulley group can form a lifting or traction device, by winding the wire rope, transport, traction, and other work. Since the rumping machine is simple, it is easy to use, so it is widely used in construction projects. Its technical performance level directly affects the production efficiency of construction projects, so it is greatly concerned by the unit. [0003] The reel is the main bearer component of the hoard, which is to wind wire rope, undertake all of the lifting load, power transmission, completion of the improvement and decent material, machine or heavy object. When the reel requires stop, the conventional braking method is to stop the re...
