The invention provides an electric hoist rope guide breakage anti-falling device, and relates to the technical field of rope guide breakage anti-falling. The anti-falling device for breakage of the rope guide of the electric hoist comprises an anti-falling mechanism, a steel wire rope, a fixing bolt, a nut, a connector, an abutting bolt, a positioning sleeve, a mounting base, an electric telescopic rod, a travel switch, a wire, a clamping groove, a mounting plate, a contact ring, a conducting strip and a power source. Meanwhile, after the steel wire rope makes contact with the contact ring, the electric telescopic rod is powered on, the travel switch in a normally-closed state can be adjusted to be in a normally-open state, the electric hoist is powered off and cannot continue to rotate, and the rope guide cannot continue to move in the electric hoist. The broken rope guide can be prevented from being extruded in the electric hoist to further damage the electric hoist and the rope guide, and later maintenance of the electric hoist and the rope guide is facilitated.
本发明提供一种电葫芦导绳器断裂防坠落装置,涉及导绳器断裂防坠落技术领域,该电葫芦导绳器断裂防坠落装置包括防脱机构、钢丝绳、固定螺栓、螺帽、连接头、抵紧螺栓、定位套筒、安装座、电动伸缩杆、行程开关、导线、卡槽、安装板、触环、导电片、电源,通过设置的钢丝绳以及触环,在导绳器出现断裂时,可以阻挡导绳器沿着电葫芦的钢索向下方坠落,保护下方工作人员的生命安全,同时钢丝绳与触环接触后,电动伸缩杆得电,能够将处于常闭的行程开关调整到常开状态,电葫芦断电无法继续转动,导绳器也无法在电葫芦内继续移动,可以防止断裂的导绳器在电葫芦内挤压而造成电葫芦和导绳器的进一步破坏,也便于后期对电葫芦以及导绳器的维修。
