The invention discloses a passive height limiting crane which comprises a lifting base, a suspension arm, a lifting hook, a rope, a power generation mechanism and a height limiting device, the suspension arm is arranged on the lifting base, one end of the rope penetrates through an arm head of the suspension arm, and the other end of the rope penetrates through the lifting hook; the power generation mechanism is suspended on the suspension arm and is axially hollow, a power generator is arranged in the power generation mechanism, and the rope penetrates through the power generation mechanism through the hollow part; and the rope contacts with a generating pulley of the power generator. By the adoption of the scheme, the generator is driven to generate electricity through movement of the rope when the crane works, all-weather stable power supply can be achieved while the structure of the power generation system is simple, interference of external factors such as weather is avoided, meanwhile, the lifting height of the lifting hook is retrieved according to the length of the rope retracted by the height limiting device, and the accuracy is high.
本发明公开了一种无源高度限位起重机,包括:起重基座、吊臂、吊钩、绳索、发电机构和高度限位装置,其中:所述吊臂设于起重基座上,绳索一端穿过吊臂的臂头,另一端穿过吊钩;所述发电机构,悬挂在吊臂上,为轴向中空,内设发电机,绳索通过中空部分穿过发电机构;绳索与发电机的发电滑轮接触。采用上述方案,通过起重机工作时绳索的运动,带动发电机进行发电,在发电系统的结构较为简单的同时,还可以实现全天候的稳定供电,不受天气等外界因素干扰,同时根据高度限位装置收起的绳索长度检索吊钩提升高度,精确度较高。
