Assembly and disassembly of large tires

Abstract

The invention relates to a detaching and installing device for a large-size tyre. The detaching and installing device comprises a tyre pressure tool. The detaching and installing device is characterized by further comprising a framework type portal, a main working oil cylinder, supporting oil cylinders and a tool platform, wherein pistons of the supporting oil cylinders are respectively connected with four corners of a tyre tray; the bottom of each supporting oil cylinder is fixed by a connection bottom plate and is fixedly arranged on a portal base plate; the tool platform is fixedly arranged on the portal base plate; the main working oil cylinder is fixedly connected onto a transverse beam of the portal. The detaching and installing device for the large-size tyre has the beneficial effects that compared with the prior art, an assembling process of a tyre and a wheel hub and a traditional detaching and installing process are combined aiming at large-size tyres with grades which are higher than 21.00-25 to realize automatic detachment and installation with a higher degree, so that the detaching and installing efficiency is greatly improved, and the safety guarantee to operators is increased. A working blank of a wharf company is filled effectively. The economic benefit is very good. About 400000 yuan of maintenance cost can be reduced in 10 years. The cost can be recovered after five years under the condition of considering the investment of preliminary-stage equipment.

Description

technical field [0001] The invention belongs to the field of motor vehicle maintenance, in particular to a dismounting device for large tires. Background technique [0002] With the extensive use of tubeless OTR equipment such as tire cranes and reach stackers at major terminals at home and abroad, the number of disassembly and assembly of large OTR tires has also increased accordingly. At present, most of the OTR tires in domestic terminals are completed manually. Due to the large size and heavy weight of OTR tires, the disassembly process is relatively cumbersome, often requiring multiple workers and various tools, and it takes a long time to complete. , and there is a great potential safety hazard. In recent years, there have often been accidents in China where workers were killed or injured when disassembling and assembling tires.

Problems solved by technology

At present, most of the OTR tires in domestic terminals are completed manually. Due to the large size and heavy weight of OTR tires, the disassembly process is relatively cumbersome, often requiring multiple workers and various tools, and it takes a long time to complete. , and there is a great potential safety hazard. In recent years, there have often been accidents in China where workers were killed or injured when disassembling and assembling tires.

[0003] Due to the difficulty in dismounting and assembling of large tires, the operating efficiency is low, and the safety hazard of operators is extremely high

Regardless of labor cost or safety cost, the traditional dismantling process has great disadvantages. The disadvantages of the traditional dismantling process are: dismantling the tire crane 21.00-25, 21.00-35 tires requires the use of 25T heavy forklifts and shoveling heavy objects, and the tires are removed Pressure, the force reaches at least 30T, which poses a great safety hazard to manual operators; the traditional process requires manual prying out of lock rings, seat rings, etc., and accidental injuries to operators have occurred in the past; The tire is pressed by heavy objects, which has the characteristics of uneven force, so it is usually extremely difficult to separate the tire and the wheel hub, and it often takes a lot of time to solve it. If the wheel hub and the tire cannot be separated, it may even be necessary to fire the wheel hub. heating

First, it is unsafe, and second, it is extremely easy to damage the physical structure of the hub
