Description

Technical Field

[0001] The invention relates to the technical field of disassembly devices, and in particular to a tire disassembly device for converting a motorhome. Background Art

[0002] With the application of new energy, cars driven by new energy such as plug-in hybrid drive, pure electric drive and fuel cell drive are gradually presented to people in the form of motorhomes. With the improvement of people's quality of life and the love of outdoor travel, motorhomes have gradually become a popular way of travel. During the long-term use of motorhomes, tires, as components that directly contact the ground, are subjected to complex road conditions and large loads, and are prone to wear and damage. In order to maintain comfort and safety during the journey, it is necessary to modify the motorhome. In order to facilitate the modification of the motorhome, a tire removal device is needed.

[0003] At present, the traditional tire removal method mainly relies on manual operation, and the tire bolts are loosened one by one with simple tools such as tire wrenches. However, since the vehicle needs to be raised when the RV is modified, and its tires are large in size and heavy in weight, the tires that are separated from the wheel hub are very likely to fall off instantly due to their own gravity during removal, which poses a serious threat to the personal safety of the modification personnel and there is a risk of injury. In addition, during the tire installation and removal process, due to the large weight of the tires, it is often necessary to use external lifting equipment to assist the operation, which not only takes up a lot of space, but also requires frequent lifting and lowering operations on the tires, greatly reducing work efficiency and increasing the complexity and inconvenience of the modification process. Summary of the invention

[0004] The present invention relates to a tire removal device for caravan modification, which comprises a torsion block capable of flexibly rotating on a top fixing frame, a torsion groove and a side stop frame on the top fixing frame, which allow the torsion block to rotate within a specific range while maintaining stability, thereby driving a shifting part and a tire support part to flexibly adjust their angles, facilitating adaptive adjustment according to the actual size of the caravan, and accurately controlling the position of the tire support part. An adjusting cylinder body and a tire clamping rod of the tire support part can stably clamp the tire, and a stabilizing frame and rollers outside the mounting frame provide good support and mobility convenience after the tire is removed, thereby greatly improving the efficiency and accuracy of tire loading and unloading. The tire support long supports the tire for a long time to prevent it from falling, thereby facilitating protection treatment for modification personnel, and the cooperation between the reversing part and the tire support part allows the tire to be twisted after removal, so that multiple lifting operations are not required during the vehicle modification process, thereby increasing its work efficiency.

The tire supporting rod supports the bottom of the tire, and the tire clamping rod clamps the tire from above. This design can effectively prevent the tire from shaking or rolling during the removal process, ensuring the safe removal of the tire. At the same time, the stable clamping method can also reduce damage to the tire and protect the integrity of the tire. The three sets of stabilizing frames outside the mounting frame and the rollers thereon can increase the stability of the tire supporting part during the tire supporting process and prevent the tire supporting part from rubbing when supporting the tire.
