Abstract

The invention belongs to the field of tool clamp design, and relates to a movable mounting device and method for a landing chassis, which improves assembly efficiency and relieves labor intensity. Themethod comprises the following steps: step I of descending a lifting mechanism to the lowest position, opening upper and lower clamping plates, mounting the landing chassis, and fixing the upper andlower clamping plates with bolts after the centers of the upper and lower clamping plates are aligned; step II of moving movable wheels of a frame, moving the landing chassis to a corresponding mounting position of the bottom of the body; step III of opening the upper and lower clamping plates, vertically placing a landing chassis support column, enabling a barrel body of the landing chassis to bein contact and alignment to an airplane fixing part, enabling the barrel body of the landing chassis to penetrate into a body part positioning hole, lifting the lifting mechanism to a proper position, slightly regulating a hand wheel, and enabling a landing chassis mounting hole to align and fix to a body mounting support base; and step IV of loosening the hand wheel to the lowest position alongthe reverse step after mounting work is ended, taking out a landing chassis movable mounting device, and returning to the initial position.

Description

technical field [0001] The invention belongs to the field of fixture design, and relates to a mobile installation device and method for landing gear. Background technique [0002] At present, manual dragging is adopted for the movement of the helicopter landing gear. During installation, the landing gear is manually lifted and installed in alignment, which is time-consuming and labor-intensive. Contents of the invention [0003] Purpose of the invention: To provide a mobile installation device and method for landing gear, which can improve assembly efficiency and reduce labor intensity. [0004] Technical solutions: [0005] A landing gear mobile installation device, comprising a vehicle frame 1, a moving bracket 2, a lifting mechanism 3, a lower splint set 4, an upper splint 5, a locking bolt assembly 6, a fixing bolt assembly 7, and a movable wheel 8; [0006] The bottom of the vehicle frame 1 is a U-shaped frame, handles are provided at the four corners of the frame, ...
