Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of tire dismounting without inner tube, especially to a tire dismounting platform without inner tube. BACKGROUND

[0002] The tire without inner tube, also known as the vacuum tire, is a pneumatic tire without inner tube, which realizes air tightness by the sealing structure between the inner wall of the tire and the rim. Compared with the traditional tire with inner tube, the tire without inner tube has the advantages of not easy to burst, strong wear resistance, good heat dissipation performance, etc., and plays a crucial role in the fields of port, mine and transportation. In the port, the tire without inner tube helps the large container truck to efficiently transfer goods; in the mine, its strong load bearing and puncture resistance ensure the stable operation of heavy mine trucks in complex road conditions; in the transportation industry, the tire without inner tube becomes the mainstream choice of logistics vehicles due to its good economy and safety.

[0003] However, there are many drawbacks in the installation and dismounting process of the tire without inner tube. When dismounting, the traditional method uses multiple long pry bars and multiple maintenance personnel to operate in turns to separate the tire and the steel ring by brute force. This pure manual high-intensity operation not only has low efficiency, but also has great safety hazards. Once the pry bar slips, the maintenance personnel is easy to fall and get hurt. In the installation process, the gap between the steel ring and the tire of the new tire, especially the retreaded tire, is large, and the installation of the sealing ring is difficult. At present, the method of pressing the steel ring with a large single bucket is commonly used to assist installation, and a piece of wood or metal block needs to be padded between the bucket and the steel ring during the operation process, but the height of the single bucket is difficult to control accurately, and the wood and metal block are easy to slip out, and the posture of the steel ring is difficult to keep flat, which not only increases the installation difficulty, but also makes the maintenance personnel face the risk of being injured by the falling objects and being squeezed by the unstable steel ring, seriously threatening the safety of personnel and the installation quality.
