Description

Technical Field

[0001] The utility model relates to the field of tire disassembling and mounting equipment, in particular to a tire rim lifting and translating device for a tire disassembling machine. Background Art

[0002] In the field of tire performance testing and maintenance of small cars (mainly sedans, SUVs, pickup trucks and other small cars), tire changers are a commonly used auxiliary equipment, mainly used for the removal and installation of tires on test or commercial rims. Taking tire removal as an example, the tire and rim assembly needs to be placed on the fixed seat of the tire changer. Traditional tire changers rely on manual handling to complete this process. For ordinary commercial alloy rims, their weight is relatively light and can be handled by one person. However, in the field of tire performance testing, the rims used are mostly solid steel rims, which are heavy and difficult for one person to handle. They require the cooperation of two or even three people, and there is a risk of injury in this process.

[0003] Chinese patent CN210553979U proposes a flip-type commercial vehicle tire changer, which can realize the side reversal of the rim fixing seat, flip it upward after the tire rim is installed on the side, and then the tire is removed and installed. Its disadvantage is that the weight of the rim fixing seat flipped together with the rim is very large, which puts a great burden on the power and flipping parts of the tire changer. The flipping parts are easy to be damaged, and the center heights of rims of different sizes are different. They cannot be directly aligned and installed on the flipping mechanism from the side, and need to be manually lifted or installed with other lifting devices. There are still problems similar to traditional tire changers. Utility Model Content
