The invention discloses an anti-falling system for a broken rope of a lifting hook. The system comprises a rack trolley, a lifting mechanism, a lifting hook mechanism, movable connecting plates, movable rotating shafts, movable lifting wheels, a lifting hook fixing seat, a lifting hook clamping device, a lifting hook structure steel plate, lifting hook guide steel plates, a clamping power mechanism, a fixed clamping vertical plate, rotary clamping seats, a clamping fixing shaft and another fixed clamping vertical plate. The four lifting hook guide steel plates mounted on the rack trolley are used for revising the traveling direction and track of the lifting hook, and the lifting hook structure steel plate pushes away the lifting hook clamping device supported by the clamping power clamping mechanism through sliding of the inclined surface of the lower part of the lifting hook clamping device, and when the lifting hook rushes to the top and breaks the rope and the lifting hook and a lifted material are in free falling motion on the guide track of the lifting hook guide steel plates, the lifting hook clamping device clamps and fixes the lifting hook structure steel plate on the lifting hook under the combined action of the clamping power mechanism (a spring and a supporting rod), so that the accident that the lifting hook and the lifted material fall to the ground is avoided.
本发明公开了一种吊钩断绳防坠系统,包括机架小车,升降机构,吊钩机构,移动连接板,移动旋转轴,移动吊轮,吊钩固定座,吊钩卡紧装置,吊钩结构钢板,吊钩导向钢板,卡紧动力机构,固定卡紧立板,旋转卡紧座,卡紧固定轴,固定卡紧立板。本发明通过安装于机架小车的四块吊钩导向钢板对吊钩行驶方向及轨迹进行修订,吊钩结构钢板利用吊钩卡紧装置下部斜面滑移推开由卡紧动力卡紧机构支撑的吊钩卡紧装置,吊钩冲顶断绳时,吊钩在吊钩导向钢板引导轨迹上与被吊材料处于自由落体运动时,吊钩卡紧装置在卡紧动力机构(弹簧及支撑杆)共同作用下将吊钩上的吊钩结构钢板进行卡紧固定,避免吊钩及被吊材料坠地事故发生。
