The invention discloses a portal crane windproof locking device which comprises portal crane walking rollers, a portal crane rail and two iron shoes, the portal crane walking rollers are installed on a portal crane and are arranged on the portal crane rail, and the two iron shoes are symmetrically arranged on the portal crane rail between the portal crane walking rollers. A forward and reverse rotation connecting lead screw is arranged between the iron shoes, two sliding grooves are symmetrically formed in the two sides of two nuts on the connecting lead screw, the nuts are screwed on the connecting lead screw, openings are formed in the rear portions of the iron shoes, and the nuts with the sliding grooves can be clamped at the openings. The arc-shaped surface of the iron shoe is attached to the gantry crane walking roller, locking of the gantry crane walking roller on the gantry crane rail is achieved, the gantry crane is prevented from being blown by wind, the structure is simple, operation is convenient, only two gantry crane walking rollers are needed in the using process, the number is obviously reduced, the response speed is increased, and meanwhile displacement caused by shaking of the gantry crane is reduced.

    本发明公开了一种门机防风锁止装置,包括门机行走滚轮、门机轨道和两个铁鞋,所述门机行走滚轮安装在门机上,且门机行走滚轮在门机轨道上,两个所述铁鞋对称设置在门机行走滚轮之间的门机轨道上,所述铁鞋之间设置有正反旋连接丝杆,所述连接丝杆上的两个螺母两侧对称的开两道滑槽,螺母旋在连接丝杆上,所述铁鞋后部开设有开口,所述开有滑槽的螺母可以卡在开口处,本发明通过转动丝杆驱动两个铁鞋相向移动,使得铁鞋弧形面与门机行走滚轮相贴合,实现对门机轨道上的门机行走滚轮的锁止,避免门机被风吹动,结构简单、操作方便,在使用时只需两个,数量明显减少,提高响应速度,同时减少吊机晃动产生移位。
