The invention discloses an overload protecting device for a suspended basket lifter during high-altitude operation, and relates to the field of high-altitude operation. The overload protecting device comprises a fixed plate, a pressure detecting column, a pressed plate and a fixed plate, wherein a plurality of grooves adaptive to the pressure detecting column are formed in opposite surfaces of the fixed plate and the pressed plate; metal contact pins are arranged inside grooves in the surfaces of the fixed plate; the pressure detecting column is blocked inside the grooves of the fixed plate and the pressed plate; output ends of the metal contact pins are electrically connected to guide wires, and the other ends of the guide wires are electrically connected to control boxes; buzzers are mounted inside the control boxes; and control units are arranged inside the control boxes. Through the independent fixed plate and the pressure detecting column, gravity center offset degree of a heavy object can be preliminarily estimated according to the shape of the heavy object; the pressure detecting column is mounted on the corresponding position, so that the device can change a stress point according to the shape of the heavy object, and thus, generality of the device is greatly improved, and practicability of the device is improved.

    本发明公开了一种高处作业吊篮升降机的过载保护装置,具体涉及高处作业领域,包括固定板、压力检测柱、受压板,固定板、受压板的相对面开设有若干与压力检测柱相适配的凹槽,固定板表面的凹槽的内部设置有金属触针,压力检测柱卡接于固定板、受压板之间的凹槽内部,金属触针的输出端电性连接有导线,导线的另一端电性连接有控制盒,控制盒的内部安装有蜂鸣器,控制盒的内部设置有控制单元。本发明通过独立的固定板与压力检测柱,在使用时可以根据重物的形状初步估算重物的重心偏移度,在相对应的位置安装压力检测柱,使得该装置可根据重物形状改变受力点,大大提高了该装置的通用性,提高该装置的实用性。
