Description

Technical Field

[0001] The utility model belongs to the technical field of port machinery and equipment, and particularly relates to a windproof zipper device for a port door machine based on bevel gear transmission. Background Art

[0002] Windbreaks for port gantry cranes are devices that secure large mechanical equipment to the ground or other stable structures through physical connection and tension. Their primary function is to increase the equipment's wind resistance, preventing movement, shaking, or even overturning in strong winds, thereby ensuring the safety of both equipment and personnel. Wuxi Huadong Heavy Machinery Co., Ltd. has developed a windbreak device (ZL 202022656172.8) that uses a sensor at the axle pin to monitor whether the windbreak is properly installed. Qingdao Port International Co., Ltd. has developed a windbreak device for gantry cranes (ZL 201821903756.7) that secures the gantry crane using a wire rope driven by a windbreak screw. Caofeidian Port Co., Ltd. has developed an easy-to-use windbreak device for gantry cranes (ZL 201821885532.8) that replaces a latch-type connection between the zipper and the ground assembly with a shackle. Furthermore, Tianjin Port Alliance International Container Terminal Co., Ltd. and Qinhuangdao Port Co., Ltd. have designed windbreak devices tailored to their specific operational needs. The windproof zippers mentioned in the above patent documents all achieve the tensioning function of the pull rod or wire rope by directly operating the pull rod or wire rope inside the zipper manually. Due to the lack of a speed change lever, the tensioning operation is relatively laborious. Utility Model Content
