The invention belongs to the technical field of crane rotation limiting and particularly relates to a crane universal rotation limiting system. The crane universal rotation limiting system comprises a rectangular box, a rotating column is mounted in the rectangular box, a mounting plate is mounted at the top of the rotating column, a plurality of mounting holes are formed in the top of the mounting plate, a push rod motor is arranged on the inner wall of the rectangular box, a power plate is connected to an output shaft of the push rod motor, a first arc-shaped limiting plate is connected to the power plate, two inclined supporting mechanisms and a lever mechanism are arranged on the power plate, side face arc-shaped limiting plates are connected to the two inclined supporting mechanisms correspondingly, a second arc-shaped limiting plate is connected to the lever mechanism, the inner side of the first arc-shaped limiting plate, the inner sides of the two side face arc-shaped limiting plates and the inner side of the second arc-shaped limiting plate are all provided with anti-skid pads, the four anti-skid pads are all matched with the rotating column, a lantern ring is mounted on the outer side of the rotating column, a limiting poke rod is mounted at the bottom of the lantern ring, and a stabilizing rod is mounted on the outer side of the lantern ring. The crane universal rotation limiting system can perform rotating and limiting automatically , meanwhile, the rotary limiting angle can be adjusted, and the use range is widened.

    本发明属于吊机回转限位技术领域,尤其是一种吊机通用回转限位系统,其包括矩形盒,矩形盒内安装有旋转柱,旋转柱的顶部安装有安装板,安装板的顶部开设有多个安装孔,矩形盒的内壁上设置有推杆电机,推杆电机的输出轴上连接有动力板,动力板上连接有第一弧形限位板,动力板上设置有两个斜撑机构和杠杆机构,两个斜撑机构上均连接有侧面弧形限位板,杠杆机构上连接有第二弧形限位板,第一弧形限位板、两个侧面弧形限位板和第二弧形限位板的内侧均设置有防滑垫,四个防滑垫均与旋转柱相适配,旋转柱的外侧安装有套环,套环的底部安装有限位拨动杆,套环的外侧安装有稳定杆。本发明可以自动回转限位,同时可以调节回转限位角度,扩大使用范围。
