The invention belongs to the technical field of cranes, and particularly relates to a windproof zipper device of a crane and a working method of the windproof zipper device of the crane. The driving mechanism is arranged in the extension rod and comprises a driver and a multi-connecting-rod assembly, the multi-connecting-rod assembly is hinged to the extension rod through a rotating shaft, and a driving shaft of the driver is connected with the two ear pulling hooks through the multi-connecting-rod assembly so as to drive the two ear pulling hooks to be opened and closed; according to the crane windproof zipper device and the working method thereof, in the opening process of the two pull lug hooks, air injection cleaning and lubricating oil coating are conducted on the interior of the lubricating groove through the linkage mechanism, so that it is guaranteed that the pull lug hooks are closed and used smoothly; meanwhile, the two pull lug hooks are only closed under the condition of strong wind, and lubricating oil in the lubricating groove is easily polluted by impurities, so that in the closing process of the two pull lug hooks, the lubricating oil in the lubricating groove is sucked through the linkage mechanism, and the lubricating oil is prevented from being polluted.

    本发明属于起重机技术领域,具体涉及一种起重机防风拉锁装置及其工作方法,本起重机防风拉锁装置包括:延伸杆;驱动机构,设置在延伸杆内,且包括:驱动器和多连杆组件,所述多连杆组件通过转轴与延伸杆铰接,所述驱动器的驱动轴通过多连杆组件与两拉耳钩相连以带动两拉耳钩开合;本起重机防风拉锁装置及其工作方法在两拉耳钩打开过程中,通过联动机构对润滑槽内进行喷气清洗和涂覆润滑油,以保证拉耳钩闭合使用时的顺畅;同时由于两拉耳钩只有在大风情况下进行闭合,润滑槽内的润滑油很容易被杂质污染,所以在两拉耳钩闭合过程中,通过联动机构吸取润滑槽内的润滑油,防止润滑油被污染。
