The invention provides a portable crane for maintaining a main rotor assembly and a main speed reducer of a helicopter. The portable crane comprises a lower supporting column, a horizontal rotating mechanism, an upper supporting column, a suspension arm assembly, a hoisting assembly and a supporting assembly, wherein the lower supporting column is connected to the upper supporting column through the horizontal rotating mechanism, and the suspension arm assembly is movably connected to the upper part of the upper supporting column; the hoisting assembly is fixed to the lower supporting column and movably connected to the suspension arm assembly, and the supporting assembly is fixed to the lower portion of the lower supporting column. The portable crane is 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; The crane adoptsthe simple and stable horizontal rotating mechanism, the suspension arm assembly and the hoisting assembly, is freely controllable in lifting speed, is small after being folded, and is not limited infixing 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 labor intensity of operators can be reduced, safety and stability are improved, and maintenance speed is increased.
本发明提供了一种用于直升机主旋翼组件和主减速器维修的轻便吊车,包括支撑下柱、水平旋转机构、支撑上柱、吊臂组件、起吊组件、支撑组件,支撑下柱通过水平旋转机构连接支撑上柱,吊臂组件活动连接在支撑上柱上部,起吊组件固定在支撑下柱上并与吊臂组件活动连接,支撑下柱下部固定支撑组件。适应野外、场外、户外绝大多数场景下的前机身部件即时性抢修,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;水平旋转机构、吊臂组件、起吊组件简易稳定,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;可减少操作者劳动强度,提高安全稳定性,提升维修的速度。
