The invention relates to the technical field of crane hanging, and discloses a crane safety monitoring and early warning device which comprises two wheel discs, the wheel discs are arranged in parallel, U-shaped blocks are fixedly installed at the bottoms of the two wheel discs, a connecting plate is horizontally arranged below the U-shaped blocks, and a hook is fixedly installed at the bottom of the connecting plate. A limiting buckle is installed on the side face of the vertical edge of the hook through a torsion rotating shaft, the top end of the limiting buckle is located on the inner ring of the hook, first detection assemblies used for detecting shaking of the limiting buckle are arranged on the opposite side faces of the hook, and a second detection assembly used for detecting movement of the connecting plate is arranged between the U-shaped block and the connecting plate. After an object is hooked by the crane hook, whether the limiting buckle shakes (has a trend of rotating downwards to be opened) or not is monitored, if the limiting buckle rotates, the first copper sheet and the second copper sheet make contact with the first alarm to work, a worker is prompted to be away from the crane, and the hooked object has the risk of unhooking and falling off; and therefore, workers have sufficient reaction time to be away from each other.

    本发明涉及起重机吊挂技术领域,公开了一种起重机安全监测预警装置,包括轮盘,轮盘有两个并平行设置,且两个轮盘底部固定安装有U型块,U型块下方水平设置有衔接板,且衔接板底部固定安装有挂钩,挂钩竖边侧面通过扭力转轴安装有限位扣,且限位扣顶端位于挂钩内圈,挂钩对立的侧脸均设有用于检测限位扣晃动的第一检测组件,U型块和衔接板之间设有用于检测衔接板移动的第二检测组件。本发明能够在起重机挂钩挂接物体后,监测限位扣是否晃动(有往下转动打开的趋势),若限位扣发生转动,则第一铜片和第二铜片接触第一警报器工作,提示工作人员远离起重机,挂接物体有脱钩掉落的风险,使得工作人员有充足的反应时间远离。
