The invention discloses an overhead mobile crane. The crane comprises a crane cantilever, a sliding mechanism, a fixing block, a pulley, a connecting block, a protection mechanism, a baffle, a pressing mechanism, a locking mechanism, a sliding rod, a movable groove, a reset spring, clamping pins, a telescopic spring and a clamping groove. The crane has the beneficial effects that the labor-savingand anti-abrasion effects are achieved through winding connection of a rope and the pulley; the baffle is tightly connected in the fixing block through abutting of the two clamping pins against the interiors of the clamping grooves, the baffle can shield the pulley from dust and impurities and prevent rainwater erosion; when the baffle is required to be dismounted, a pressing mechanism is pressed,the sliding rod slides downwards, the two clamping pins reset under the action of the telescopic springs and are separated from the clamping grooves, the baffle is convenient to dismount, and quick replacement is facilitated; when the baffle is replaced, the bottom of one end of the baffle is clamped with one side of the top of the fixing block, the baffle is tightly connected under the abuttingaction of the clamping pins against the clamping grooves, and the pulley is conveniently shielded and protected.

    本发明公开了一种高架移动式起重机,包括起重机悬臂、滑动机构、固定块、滑轮、连接块、防护机构、挡板、按压机构、闭锁机构、滑杆、活动槽、复位弹簧、卡销、伸缩弹簧和卡槽。本发明的有益效果是:通过绳索与滑轮的缠绕连接,起到省力和防磨损作用,通过两个卡销与卡槽内部的抵触,使挡板在固定块内部连接紧密,有利于使挡板对滑轮进行遮挡灰尘杂物和防止雨水侵蚀,当需要对挡板拆除时,通过按压按压机构,使滑杆向下滑动,使两个卡销在伸缩弹簧的作用下复位,并与卡槽分离,方便挡板拆卸,有利于进行快速更换,当更换完毕后,将挡板的一端底部与固定块顶部一侧卡合,在卡销和卡槽的抵触下,使挡板连接紧密,方便对滑轮进行遮挡防护。
