The invention provides a self-supporting crane for maintaining a tail speed reducer and a tail rotor blade of a helicopter. The self-supporting crane comprises a lower supporting column, a horizontalrotating mechanism, an upper supporting column, an angle adjusting mechanism, a suspension arm and a hoisting mechanism, wherein the lower supporting column is connected to the upper supporting columnthrough the horizontal rotating mechanism, and the upper supporting column is connected to the suspension arm through the angle adjusting mechanism; and the hoisting mechanism is mounted on the suspension arm. The self-supporting crane can be suitable for immediate repair of helicopter body tail parts in most of outdoor, off-site and outdoor scenes, can solve the problem of rapid repair of helicopters in environments without flat ground and electric power, and can solve the problem of emergency maintenance to the maximum extent. The crane adopts the simple and stable horizontal rotating mechanism and angle adjusting mechanism, is freely controllable in lifting speed, is small after being folded, and is not limited in fixing mode by geography; the weight is reduced due to the compact structure, and the effects of convenience in carrying and quick response are achieved; and workload and labor intensity of operators can be reduced, safety and stability are improved, and maintenance speedis increased.

    本发明提供了一种用于直升机尾减速器和尾桨叶维修的自体支撑式吊车,包括支撑下柱、水平旋转机构、支撑上柱、角度调节机构、吊臂、起吊机构,支撑下柱通过水平旋转机构连接支撑上柱,支撑上柱通过角度调节机构连接吊臂,起吊机构安装在吊臂上。可适应野外、场外、户外绝大多数场景下的直升机机身尾部部件即时性抢修,可以解决直升机在一无平地、二无电力的环境里快速抢修的问题,可最大化的解决突发维修问题;吊车水平旋转机构、角度调节机构简易稳定,升降速度自如可控,收放小巧可折叠,固定方式不受地理限制;紧凑型结构减轻了重量,达到方便携带、快速反应的效果;可减少操作者的工作量和劳动强度,提高安全稳定性,提升维修的速度。
