The invention provides an anti-collision protection device for a single-beam crane, which comprises a bearing box arranged on the side surface of the single-beam crane, which is easy to collide; the protection rod is slidably arranged in a sliding hole in the side face, away from the single-beam crane, of the bearing box; the buffering assembly is connected with the inner end of the protection rod; the ejection assembly is used for ejecting the protection rod out of the bearing box; the triggering power-off assembly is electrically connected with a walking motor of the single-beam crane, the triggering power-off assembly corresponds to the inner end of the protection rod, and the inner end of the protection rod makes contact with the triggering power-off assembly to achieve power off of the walking motor of the single-beam crane. According to the scheme, the power-off of the walking motor of the single-beam crane is achieved by triggering the power-off assembly after the protection rod collides, and serious collision is avoided in cooperation with the buffering assembly; the protection rod is pushed through the ejection assembly, so that the single-beam crane can be far away from a collision object, and continuous collision of the single-beam crane caused by misoperation of an operator is avoided.

    本发明提供一种单梁起重机防撞保护装置,包括:承载箱,设置在单梁起重机容易发生碰撞的侧面;防护杆,滑动设置在所述承载箱远离单梁起重机的侧面的滑动孔内部;缓冲组件,所述缓冲组件与所述防护杆的内端相连接;顶出组件,用于将所述防护杆向承载箱外部顶出;触发断电组件,与单梁起重机的行走电机电连接,所述触发断电组件与所述防护杆内端相对应,所述防护杆内端与触发断电组件接触实现单梁起重机的行走电机断电。本发明的方案通过触发断电组件在防护杆碰撞后实现单梁起重机行走电机的断电,配合缓冲组件,避免严重碰撞;通过顶出组件推动防护杆,能够使单梁起重机远离碰撞物,避免操作人员误操作造成单梁起重机连续碰撞。
