[0021] Working principle: during operation, when it is necessary to repair the aircraft wheel 7, the equipment is moved to the back of the aircraft wheel 7, so that the positions of the two fixed movable seats 3 correspond to the positions of the two wheel bodies 702, and the self-locking roller at the bottom end of the fixed movable seat 3 is locked, and then the first motor 410 is turned on to make the double-headed screw 409, because the two sliding blocks 408 are threadedly connected with the thread grooves in the direction opened on the double-headed screw 409, the two sliding blocks 408 are driven to approach each other, thereby driving the two cross bars 406 to approach each other, and then the movable movable seat 401 is pushed to move toward the side away from the connecting seat 1 through the two connecting rods 407, until the push plate 403 moves to the lower part of the middle position of the connecting shaft 701, and then the first jack 402 is turned on to push the push plate 403 to move upward, so that the inner arc surface of the push plate 403 contacts the outer wall of the connecting shaft 701, and the wheel 7 is lifted up under the action of the first jack 402; After the wheel body 702 is lifted upward to be higher than the top of the limiting belt 510, the lifting is stopped, and then the self-locking roller at the bottom of the movable movable seat 401 is locked, and the self-locking roller at the bottom of the fixed movable seat 3 is opened, and then the first motor 410 is supplied with reverse current to make the double-headed screw 409 rotate in the opposite direction, so that the two cross bars 406 move back, and since the movable movable seat 401 is fixed, the connecting seat 1 is pulled toward the movable movable seat 401 through the connecting rod 407 until the two limiting belts 510 move to the bottom of the two wheel bodies 702 respectively, and then the machine wheel 7 is moved downward by the first jack 402, so that the two wheel bodies 702 enter the inner sides of the two limiting belts 510, so that the limiting belts 510 limit the wheel bodies 702; During use, the first jack 402 and the second jack 502 are used to lift the wheel 7, so that the wheel 7 can be easily repaired. When the outer surface of the wheel body 702 needs to be inspected and maintained, the second motor 5094 is turned on to rotate the active limiting roller 5091. Since the active limiting roller 5091 is in close contact with the inner wall of the limiting belt 510, the limiting belt 510 is driven to move. Since the limiting belt 510 is in close contact with the outer wall of the wheel body 702, the wheel body 702 is rotated under the action of friction during the movement of the limiting belt 510, thereby facilitating the inspection and maintenance of the outer surface of the wheel body 702. When the wheel body 702 on one side needs to be replaced, the cylinder 506 on one side is turned on to push the upper support plate 504 toward the movable seat 401, so that the limiting belt 510 on the side of the wheel body 702 to be replaced moves to the bottom of the connecting shaft 701, so that the wheel body 702 on one side is suspended, thereby facilitating the replacement and maintenance of the wheel body 702; When the limiting belt 510 on one side moves to the bottom of the connecting shaft 701, the mounting plate 507 moves toward the side of the movable movable seat 401, so that the tooth plate 602 moves toward the side away from the movable movable seat 401, and the tooth plate 602 is meshed with the gear 606 on the other side, thereby driving the rotating shaft 605 at the end of the rotating frame 604 to rotate upward around the mounting frame 603 until the clamping block 607 is pressed against the top wall of the wheel body 702 that does not need to be replaced, thereby improving the clamping and fixing effect of the wheel 7 and improving the stability of replacement and maintenance of the wheel body 702 on one side.
