Embodiment Construction

[0012] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0013] see figure 1 , A specific embodiment of the present invention mainly includes a left and right lead screw sliding mechanism 1 each, two lower beams 2, a movable frame 3 and a left and right wheel claw mechanism 4 each. The left and right lead screw sliding mechanisms are welded together with the two lower beams to form the frame of the equipment; the lower end of the movable frame is connected to the oblique arms in the left and right lead screw sliding mechanisms through hinge joints, and the slider on the movable frame can be placed in the lead screw sliding mechanism The vertical column slides up and down; the claw mechanism is connected with the nut B in the movable frame through bolts.

[0014] see figure 2 , the screw sliding mechanism 1 of the equipment is divided into left and right symmetrical parts, mainly including a sli...

Abstract

The invention belongs to an airplane wheel turnover technology, and relates to an airplane wheel dismounting and mounting mechanism. The airplane wheel dismounting and mounting mechanism comprises a left screw rod sliding mechanism, a right screw rod sliding mechanism, a movable frame, a left wheel claw mechanism and a right wheel claw mechanism. Each screw rod sliding mechanism comprises a screw rod nut mechanism A, a linear sliding rail mechanism and a vertical column. Each linear sliding rail mechanism comprises a sliding rail, a sliding block A and an oblique support arm. Each sliding block A is combined with a nut A of the corresponding screw rod nut mechanism A into a whole and can slide linearly along the sliding rail of the corresponding linear sliding rail mechanism. The airplane wheel dismounting and mounting mechanism is easy, convenient and flexible to operate, and has good practical application value.

Description

technical field [0001] The invention belongs to the aircraft wheel overturning technology, and relates to an aircraft wheel disassembly mechanism. Background technique [0002] Generally, when disassembling and assembling the wheels of an aircraft, the dismantling equipment disengages the wheels from the axles, and then directly drags the wheels away. [0003] When disassembling and assembling the inner wheel of the main landing gear of a certain type of aircraft, since the channel for entering and exiting the inner side of the landing gear compartment is below the fuselage, the height of the channel is only 600mm when the aircraft is at its maximum weight. The height (including the wheel height) must be less than 600mm. Since the diameter of the wheel is about 1250mm and the thickness is 500mm, the wheel must be in the down state when entering and leaving the channel; and because the weight of the wheel is about 150kg, the wheel dismounting equipment must be provided with ...
