Hydraulic tire changer and usage method

Abstract

The invention relates to a hydraulic tyre disassembling and assembling machine and an application method, and belongs to the field of tyre disassembling and assembling devices. The hydraulic tyre disassembling and assembling machine is characterized by comprising a disassembling and assembling mechanism and a hydraulic station, wherein the disassembling and assembling mechanism is connected with the hydraulic station through an oil pipe; the disassembling and assembling mechanism comprises a base, a tyre core, a hydraulic oil cylinder, a presser, a lower disc, an upper disc and nuts, the base of the hydraulic oil cylinder is in bolt connection with the base; a piston rod of the hydraulic oil cylinder, the upper disc and the lower disc are in sleeving connection, and are fixed by the nuts; through holes are oppositely formed in the upper disc and the lower disc; the tyre core which sleeves the hydraulic oil cylinder is formed by the welding of a steel barrel and a flange and is connected with the base; the presser is manufactured by steel forging, and is fixed between the upper disc and the lower disc by cylindrical pins; and the hydraulic station consists of an oil tank, a filter, an oil pump, a motor, an overflow valve, a hand operated reversing valve, a speed adjusting valve and a high-pressure oil pipe which are connected, and is used for supplying power to the device. The hydraulic tyre disassembling and assembling machine disclosed by the invention has the advantages of being simple in structure, stable in operation, low in cost of investment, and can be disassembled for transferring; and potential safety hazards caused by that tools for manually disassembling a tyre are bounced are eliminated, damage to the tyre is low, the labor intensity is reduced, and the efficiency for disassembling and assembling the tyre is improved.

Description

technical field [0001] The invention belongs to the technical field of tire dismounting devices, and in particular relates to a hydraulic tire dismounting machine and a usage method. Background technique [0002] Large-scale shoveling machinery is put into mining production to adapt to the expansion of mine scale and the needs of the rapid development of the mining industry. The carrying capacity of large-scale shoveling machinery is related to the size of the tires used. The expansion of mine scale requires large-scale shoveling machinery to use large-scale Tires are used to increase their carrying capacity. Tires are one of the most important wearing parts of scraper machinery, and their maintenance and repair is particularly important. When repairing tires, it is generally necessary to disassemble the tires. [0003] The main task when dismantling a tire is to separate the tire from the rim. For the case where the tire is not tightly bonded to the rim, the traditional me...

AI Technical Summary

Problems solved by technology

The disadvantage is that it is very difficult to manually disassemble tires. Usually, 3 to 5 people can only disassemble and assemble one tire a day, which is time-consuming and laborious; It will cause damage to the rim. Even if the steel wire is broken when using a 20-ton crane for lifting, the tire cannot be removed; the crowbar, triangle iron, screwdriver and other tools used to manually dismantle the tire have potential safety hazards when they are used.

[0004] At present, there are some tire removal tools on the market, including hand-held and machine tool types: hand-held tire removal tools are heavy, and the labor intensity of workers is very high, and they need to be used in conjunction with various tools for prying rims, frequent tool replacement, and high work efficiency. Low; machine tool type dismantling machine has complex design and high manufacturing requirements, and the cost of a machine is 200,000 to 300,000 yuan. It is easy to be damaged under the harsh operating environment of the mine, which increases the operating cost of the mine.

[0005] The labor intensity of the tire installation process is lower than that of separating the tire from the rim when dismantling the tire, but the overall installation process still requires more manpower and low work efficiency
