[0002] The winch hoist is a mechanical device in water conservancy equipment that can be closed automatically, and is often used to operate fast gates. This device is connected to the gate through a cable pulley or a cable as a hanger, and uses the gear transmission system to release the cable and winch drum to drive the lifting machinery.

[0003] The winch-type gate hoist in the prior art usually has a lifting hole to guide the steel cable when in use. How to close the lifting hole to prevent dust and insects from entering without affecting the operation of the project has always been a major problem that has troubled project managers. In addition, water stains will remain on the surface of the steel cable when it is in use. When the steel cable is reeled in, if the water stains are not cleaned, the steel cable will corrode after a period of use, reducing the service life of the steel cable. Therefore, it is necessary to design a lifting hole closing device for a winch-type gate hoist to solve the above problems. Utility Model Content
