The invention belongs to the technical field of aviation cockpits and seats, and particularly relates to a crane for disassembling and assembling an electrically-driven self-walking cockpit seat of an airplane. The vehicle body is supported on the ground through the universal ground feet and the ground foot supporting arms, and meanwhile, the first-order arm, the second-order arm and the third-order arm can be contracted, so that the effects of stabilizing the crane and facilitating folding and recycling are achieved, and the problems that the height is too high and swinging is caused in the transportation process due to the fact that lifting arms of most existing mounting cranes cannot be folded are solved; the stability of the crane is improved, and the occupied space of the crane is reduced. The lifting hook is rotated in multiple directions through the rotary support and the rotary seat, and meanwhile, the torque of a lifted weight is kept not to be exceeded, so that the effect of smaller friction loss between parts is achieved, and the problem that the precision is inaccurate due to the fact that the parts and transmission gears and bearings of the parts are abraded after an existing crane is used for a long time is solved; the practicability of the crane is improved, and the service life of the crane is prolonged.

    本发明属于航空座舱盖及座椅技术领域,尤其涉及一种飞机电驱动自行走座舱盖座椅拆装用吊车。通过万向地脚和地脚支撑臂将车体支撑在地面,同时一阶臂、二阶臂和三阶臂可以进行收缩,从而达到稳定吊车以及便于折叠回收的效果,解决了现有的安装吊车大多数都不能对吊臂进行折叠,从而导致高度过高,运输过程中摆晃的问题,提高了吊车的稳定性,减小了吊车的占用空间。通过旋转支撑和旋转座对吊钩进行多方位旋转,同时保持不超过所吊装重物力矩,从而达到较小零件之间摩擦损耗的效果,解决了现有的吊车在长时间使用之后零件和零件的传动齿轮、轴承都会发生磨损,从而导致精度不准确的问题,提高了吊车的实用性,延长了吊车的使用寿命。
