The invention belongs to the landing gear design technology, and relates to a skid landing gear and a cross beam height adjusting mechanism thereof. The skid landing gear comprises a left cross beam,a right cross beam, a left machine body joint, a right machine body joint, a sliding block, a machine body joint and a screw, the left cross beam is L-shaped, and the corner of the left cross beam isconnected with the fuselage through a left fuselage joint; the right cross beam is L-shaped, and the corner of the right cross beam is connected with the fuselage through a right fuselage joint; firstthrough holes are formed in the left end and the right end of the sliding block in the heading direction of the machine body. Double lugs are arranged at the right end of the left cross beam and connected with the first through holes in the left end of the sliding block. Double lugs are arranged at the left end of the right cross beam and are connected with the first through holes in the right end of the sliding block. A threaded hole is formed in the center of the sliding block in the vertical direction, and one end of the screw is connected with the threaded hole in the sliding block. The other end of the screw is connected with the machine body through a machine body connector and can freely rotate relative to the machine body. A limiting device is arranged on the machine body connector and used for limiting axial movement of the screw. The screw is used for driving the left and right cross beams to rotate by taking the left and right machine body joints as axes by rotating the distance between the adjusting slide block and the machine body.
本发明属于起落架设计技术,涉及一种滑撬起落架及其横梁高度调节机构。包括:左横梁、右横梁、左机身接头、右机身接头、滑块、机身接头和螺杆;左横梁为L型,左横梁拐角处通过左机身接头与机身连接;右横梁为L型,右横梁拐角处通过右机身接头与机身连接;滑块左右两端沿机身航向设有第一通孔,左横梁右端设有双耳与滑块左端第一通孔连接,右横梁左端设有双耳与滑块右端第一通孔连接;滑块中央沿竖直方向设有螺纹孔,螺杆一端与滑块上的螺纹孔连接;螺杆另一端通过机身接头与机身连接并可相对于机身自由旋转,机身接头上设有限位装置用于限制螺杆轴向运动;螺杆用于通过旋转调节滑块相对于机身的距离从而带动左、右横梁以左、右机身接头为轴旋转。
