Tire mounting and dismounting device

Abstract

The invention relates to a tire mounting and dismounting device which comprises a base and a frame connected with the base. The invention is characterized in that one lateral side of the base is vertically provided with a wheel rim positioning mechanism A for supporting the tire; the frame is provided with an elevating mechanism; the corresponding lateral side of the elevating mechanism is provided with a rotating drum A1; the corresponding extending end of the rotating drum A1 is connected with a conical sleeve for pressing against the inner circle of the side face of the tire; the wheel rimpositioning mechanism A is hinged with the base through the lower end part of a longitudinal support rod which is connected to the lower end part of the wheel rim positioning mechanism A; the upper end of the longitudinal support rod is hinged with a hydraulic cylinder push rod so that the wheel rim positioning mechanism A can swing; the bottom end of the hydraulic cylinder is hinged with the base so that the hydraulic cylinder is positioned on the swing plane of the longitudinal support rod of the wheel rim positioning mechanism A; the center of the rotating drum A1 is provided with a retractable rod; and the end part of the retractable rod is connected with an L-shaped draw hook through a chain. The invention can be used for conveniently mounting and dismounting a tire.

Description

technical field [0001] The invention relates to a tire assembly and disassembly device, which is suitable for maintenance and repair of automobiles. Background technique [0002] Tires are usually composed of three parts: outer tire, inner tube, and cushion belt. There are also those that do not need an inner tube. The inner layer of the carcass has a rubber layer with good airtightness and needs to be equipped with a special rim. [0003] Tires are ground-rolling circular elastic rubber products assembled on various vehicles or machinery, usually installed on metal rims, which can support the body, buffer external impact, realize contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions. They are subjected to various deformations, loads, forces, and high and low temperature effects during driving. It is inevitable that they will be worn or damaged. Therefore, maintenance and repairs are required...
