The invention provides a broken rope anti-falling device for a bridge crane and a control method, and belongs to the technical field of safety protection of bridge cranes. The problem that in the prior art, due to the fact that a steel wire rope of a bridge crane is not overhauled in time, rope breaking and object falling are prone to occurring is solved. The broken rope anti-falling device for the bridge crane comprises a shell, a wedge block seat is rotatably arranged in the shell, a mounting hole allowing a steel wire rope to penetrate through is formed in the wedge block seat, a wedge block is arranged in the mounting hole, and the larger end of the wedge block abuts against the inner side wall of the shell. The wedge block can be pushed by the inner side wall of the shell to be inserted into the installation hole towards the small end, and the steel wire rope is tightly pressed on the hole wall of the installation hole. The device has the advantage that the safety accident of object falling caused by breakage of the steel wire rope of the bridge crane can be avoided.
本发明提供了一种用于桥式起重机的断绳防坠装置及控制方法,属于桥式起重机安全防护技术领域。它解决了现有技术中桥式起重机的钢丝绳由于检修不及时容易出现断绳坠物的现象的问题。本用于桥式起重机的断绳防坠装置包括壳体,壳体内可转动地设置有楔块座,楔块座上开设有供钢丝绳穿设的安装孔,安装孔内设置有楔块且楔块的较大端与壳体的内侧壁相抵接,当楔块座转动时,楔块能够在壳体内侧壁的顶推下向较小端插入安装孔内并将钢丝绳压紧在安装孔的孔壁上。本发明具有能避免桥式起重机因钢丝绳断裂而发生坠物安全事故的优点。
