The invention provides a bridge crane hook dangling limiting mechanism which comprises a fixing frame, a left electric push rod and a right electric push rod, and the left electric push rod and the right electric push rod are fixedly installed on the two sides of the top of the fixing frame respectively. A left electric push rod and a right electric push rod are installed on the two sides of the fixing frame correspondingly, dragging rods are installed on output shafts of the left electric push rod and the right electric push rod correspondingly, and when the crane carriage moves forwards, the left electric push rod located on the rear portion stretches, so that a lifting rope on the rear portion is pulled by dragging a limiting base, and the lifting rope is lifted. And similarly, when the hoisting trolley stops, the right electric push rod in the front extends, so that the hoisting hook and the heavy object have the trend of moving backwards, the impulsive force brought by inertia of the heavy object is counteracted, and dangling can be effectively prevented. And the use safety is improved.

    本发明提供一种桥式起重机吊钩悬摆限位机构,包括固定框、左电动推杆和右电动推杆,所述左电动推杆和右电动推杆分别固定安装在固定框顶部的两侧,该桥式起重机吊钩悬摆限位机构设计合理,固定框的两侧分别安装了左电动推杆和右电动推杆,左电动推杆和右电动推杆的输出轴上均安装了拖拽杆,当起重小车前行时,处于后方的左电动推杆伸展,从而通过拖拽限位座拉动后方的吊绳,从而使吊钩和其上的重物具有向前移动的趋势,进而使起重小车和吊钩能够同步前行,同理,当起重小车停止时,处于前方的右电动推杆伸展,使吊钩和重物具有向后移动的趋势,抵消重物的惯性带来的冲力,能够有效地防止产生悬摆,提高使用的安全性。
