[0015] Working principle: When removing the tire of a vehicle, first start the mobile chassis, move the mobile chassis to the bottom of the vehicle, start the second hydraulic cylinder, and the output end of the second hydraulic cylinder moves upward, thereby driving the top plate to move upward. When the top plate is about to approach the bottom of the vehicle, continue to start the mobile chassis, so that the wheel removal mechanism is aligned with the upper gear, continue to start the second hydraulic cylinder, and use the rotation of the support plate to support the top plate, and then use the top plate to lift the vehicle;

[0016] The motor is started, and the output end of the motor rotates to drive the gear to rotate. The gear rotates to drive the two ends of the movable frame to move toward the middle by using the rack, so that the wheel removal mechanism can be stopped outside the wheel. After the wheel is removed by using the wheel removal mechanism, the motor is started again, and the movable frame moves outward, so that the wheel removal mechanism can be used to move the replaced wheel out of the vehicle;

[0017] When the wheel is disassembled, the wheel disassembly mechanism is stopped outside the wheel by using the folding mechanism, and then the hydraulic cylinder 1 is started. The output end of the hydraulic cylinder 1 extends out and drives the rotating disk to rotate. After the rotating disk rotates, it drives one end of the driving arm to rotate clockwise, so that it can drive the middle of the driving arm to move under the limit of the rotating frame, thereby driving the adaptive clamping assembly to move toward the middle, and then the wheel can be clamped and tightened. At this time, the motor is started, and the output end of the motor rotates and drives the rotating shaft to rotate. After the rotating shaft rotates, it drives the power gear to rotate. After the power gear rotates, it drives the rotating disk to rotate. After the rotating disk rotates, it drives the hydraulic rod to rotate, so that the driven gear, the rotating rod and the sleeve can be driven. The motor is turned off and the output end is extended to drive the movable housing to move outward, thereby driving the rotating shaft and the power gear to move. At this time, the power gear is released from the engagement with the rotating toothed disc and can be engaged with the driven gear. At this time, the motor is started again, and the driven gear is driven to rotate by the rotation of the power gear, and then the rotating rod is driven to rotate by the driven gear, and then the sleeve is driven to rotate. Therefore, the sleeve can be used to tighten the bolts on the wheel. When the sleeve moves in the direction of the tire bolt, the folding mechanism is also used to drive the wheel removal mechanism to move to the middle, and then the sleeve can be driven to move in the direction of the wheel bolt.

[0018] When the folding mechanism is used to drive the mounting frame to move toward the middle, since the adaptive clamping assembly is already tightly clamped on the outside of the wheel, when the mounting frame moves toward the wheel, it can drive the fixing rod to move toward the wheel, and then the limit plate can be used to compress the reset spring, and the limit bar and the sliding groove are used to cooperate for limiting. Therefore, when the sleeve moves toward the upper direction of the wheel bolt, it does not need to leave the wheel surface. When the rotating small wheel contacts the outer surface of the wheel, it rotates. At the same time, the rotation of the rotating half wheel and the rotating semicircle can adapt to the curvature of the wheel, so that the rotating small wheel is close to the outer surface of the wheel to achieve tight clamping.

[0019] The present invention provides a telescopic and foldable wheel disassembly device, which has the following beneficial effects:

[0020] 1. The present invention jacks up the vehicle through the vehicle body jacking mechanism, adjusts the position of the wheel removal mechanism through the folding mechanism, and uses the wheel removal mechanism to remove the wheel from the vehicle, thereby realizing automatic wheel removal, reducing manual participation, and having a high degree of automation, thereby facilitating the removal and replacement of the wheel, saving time and labor, and improving the efficiency of wheel removal and replacement.

[0021] 2. The present invention can make the clamping part of the rotating small wheel close to the outer surface of the wheel through the setting of the adaptive clamping component, so that the wheel can be clamped more stably, preventing the wheel from falling, protecting the wheel, preventing secondary damage to the wheel, and increasing the service life of the wheel. At the same time, since manual participation is reduced, safety hazards are reduced. BRIEF DESCRIPTION OF THE DRAWINGS
