[0007] As a preferred dustproof sealing device for a gate hoist of the utility model, a rope threading hole is provided at the center of the movable frame, and a connecting flange is installed at the front side of the movable frame and at the rope threading hole.

[0008] As a preferred dustproof sealing device for a gate hoist of the utility model, the left side of the second accordion cloth is fixedly connected to the left side of the inner wall of the frame, and the right side of the third accordion cloth is movably connected to the right side of the inner wall of the frame.

[0009] As a preferred dustproof sealing device for a gate hoist of the utility model, the front and rear sides of the first accordion cloth, the second accordion cloth and the third accordion cloth are movably connected to the inner wall of the frame.

[0010] As a preferred dustproof sealing device for a gate hoist of the utility model, the first accordion cloth, the second accordion cloth and the third accordion cloth are all made of nylon material.

[0011] As a preferred dustproof and plugging device for a gate hoist of the utility model, the upper and lower sides of the movable frame are rotatably connected with pulleys, and the pulleys are movably connected to the inner wall of the frame.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model can adapt well to the reciprocating motion of the wire rope in the opening and closing process through the movable connection between the mobile frame and the frame, and the coordinated use of the first accordion cloth, the second accordion cloth and the third accordion cloth, and maintain good sealing without affecting the normal operation of the hoist. The wire rope passes through the mobile frame through the rope threading hole. When the wire rope drives the mobile frame to move, the mobile frame drives the first accordion cloth, the second accordion cloth and the third accordion cloth to expand and contract inside the frame to achieve a sealing effect, effectively block the entry of dust, moisture and other pollutants, and improve the protection level and service life of the equipment.

[0014] 2. The utility model ensures the stable installation of the whole device by arranging a horizontal plate and a connecting piece at the bottom of the frame, and the rope threading hole in the center of the mobile frame cooperates with the connecting flange, so that the device is closely integrated with the wire rope system of the gate hoist, which increases the stability of the system. The movable connection design of multiple accordion cloths and the inner wall of the frame is convenient for regular inspection and replacement of the accordion cloths, and the use of pulleys simplifies the moving mechanism of the mobile frame and improves the overall maintainability of the device. Nylon is used as the material of the accordion cloth. Nylon material has good wear resistance, weather resistance and elasticity. It can withstand the friction and environmental factors during the operation of the gate hoist while ensuring the sealing performance, thereby extending the service life.
