Description

Technical Field

[0001] The utility model relates to the technical field of winches, in particular to a fixing protective device for a winch in a construction project. Background Art

[0002] A winch is a small and light lifting equipment that uses a drum to wrap a wire rope or chain to lift or pull heavy objects. It is also called a winch. The winch can lift vertically and pull heavy objects horizontally or at an angle. The winch is divided into manual winches and electric winches. Electric winches are the main ones now. They can be used alone or as a component of machinery such as lifting, road construction and mine hoisting. They are widely used due to their simple operation, large rope winding capacity and easy relocation. They are mainly used for lifting or towing materials in construction, water conservancy projects, forestry, mines, docks, etc.

[0003] In the prior art, Chinese patent publication number CN110329933B discloses a winch and a winch control method thereof, including a bottom plate, a suspension, an active motor, a drum, a wire rope, an emergency stop brake mechanism, a first wire arrangement mechanism and a second wire arrangement mechanism, wherein the electromagnetic slide rail is provided with the first wire arrangement mechanism, the inner side of a side vertical plate is provided with an active motor, the active motor is provided with an active gear plate through an active shaft, the active gear plate is provided with an emergency stop brake mechanism, a drum is provided at one end of the active shaft away from the active motor, a wire rope is provided on the drum, and a second wire arrangement mechanism is provided on the bottom plate below the drum; the present invention can ensure that the winch can brake in time when encountering an emergency fall of a heavy object during the lifting process through the emergency stop brake mechanism transmission ratchet, active pawl and non-return pawl, so as to avoid danger, and can ensure that the wire is tightly wound without looseness and disordered winding during the winding process of the winch through the first wire arrangement mechanism and the second wire arrangement mechanism, thereby improving the winding stability and efficiency of the winch.

[0004] However, the winch needs to be installed at a high place to lift materials at a low place. When fixing the winch, the winch is generally fixed on a platform, and the platform is fixed on a base surface. Therefore, the distance between the winch and the cargo cannot be adjusted. During the lifting process, the distance between the winch and the cargo cannot be flexibly adjusted. At the same time, when the winch is operating, the winch cannot protect the surrounding area of ​​the winch. Therefore, the above problems need to be improved. Utility Model Content
