The invention provides an alarm device for preventing an operation crane from accidentally touching high-voltage live equipment. The alarm device comprises a bottom plate, an extension plate, a trigger conductive box and an alarm box, the bottom plate is fixedly mounted at the outer top end of the operation room; one end of the extension plate is movably connected with the bottom plate and can be fixed on a corresponding limiting position in a plurality of preset limiting positions of the bottom plate through a limiting structure, and the other end of the extension plate is fixedly provided with a trigger conductive box and can do telescopic motion towards the direction of the suspension arm; the trigger conductive box is driven by the extension plate to the position over the suspension arm, a height meeting the preset condition is reserved between the trigger conductive box and the suspension arm, and if the suspension arm ascends to exceed the height, the trigger conductive box is triggered, and alarming of the alarm box is achieved. And if the lifting height of the suspension arm is lower than the height, the trigger conductive box is not triggered, and the alarm box does not give an alarm. The device is simple in structure, convenient to operate, time-saving and labor-saving, and capable of giving an alarm when the distance between the operation crane and the high-voltage live equipment is insufficient.

    本发明提供一种防作业吊车与高压带电设备误碰的报警装置,包括底板、延伸板、触发导电盒和报警盒;底板固定安装于操作室的外顶端上;延伸板的一端与底板活动连接并能通过限位结构固定在底板预设的多个限定位置中相应的一个上,其另一端固定有触发导电盒并能朝吊臂的方向进行伸缩运动;触发导电盒由延伸板驱动至吊臂的正上方并与吊臂之间预留有满足预定条件的高度,若吊臂上升超过该高度时,触发该触发导电盒,实现报警盒报警;若吊臂上升高度低于该高度时,不触发该触发导电盒,实现报警盒不报警。实施本发明,结构简单,操作方便且省时省力,能对作业吊车与高压带电设备之间的距离不足问题进行报警。
