The invention relates to the technical field of unmanned aerial vehicles, in particular to a bridge inspection unmanned aerial vehicle frame which comprises a bottom block, a cylinder, elastic supporting legs, a fixing plate, a lifting column and a chassis, and an annular groove is formed in the inner wall of the cylinder. According to the bridge inspection unmanned aerial vehicle rack, a cylinder drives a lifting column to move upwards in a second round hole, a first linkage column relieves limiting of a triangular block, the first linkage column moves upwards to the slope face of the triangular block, a second reset spring in a stretching state is reset, a round handle drives a sliding column to slide into a third round hole, and the triangular block is fixed through a second reset spring; and a triangular block extrudes a first linkage column to drive a lifting column to move upwards, and a chassis moves upwards in an annular groove, so that negative pressure is generated in elastic supporting feet, the elastic supporting feet are tightly adsorbed to the airport apron surface, the stability of the unmanned aerial vehicle body is improved, and the phenomenon that the unmanned aerial vehicle body bounces when falling to the ground is prevented.

    本发明涉及无人机技术领域,具体为一种桥梁巡检无人机机架,包括底块,底块、圆筒、弹性支脚、固定板、升降柱以及底盘,圆筒的内壁开设有环形槽。本发明的一种桥梁巡检无人机机架,通过圆筒带动升降柱在第二圆孔的内部上移,第一联动柱解除对三角块的限位,且第一联动柱上移至三角块的坡面处,处于拉伸状态的第二复位弹簧进行复位,且圆柄带动滑动柱滑向第三圆孔的内部,而三角块通过挤压第一联动柱带动升降柱上移,底盘在环形槽的内部上移,从而使弹性支脚的内部产生负压,使得弹性支脚紧紧吸附在机坪面上,从而提高无人机本体的稳定性,防止无人机本体本体落地时发生弹跳现象。
