Description

Device for disassembling tire and wheel rim of large-scale mining vehicle

Technical Field

The utility model belongs to the engineering machine tool field. Relates to a mechanical dismounting device, in particular to a device for dismounting tires and wheel rims of large mining vehicles.

Background

At present, a tire dismounting machine is used in a large-scale mine in China, but the equipment is expensive in cost and is not suitable for large-scale use, at present, no wheel hub and planet carrier dismounting tool is used for completing operation in China, and a small-scale mine basically uses manpower to replace tires, so that the labor intensity is high, and great potential safety hazards exist. When the wheel hub and the wheel-side planet carrier are dismounted, the hand-pulling block cannot be used for hoisting due to the fact that objects are heavy and the space is small, only the forklift can be used for matching operation, at present, the whole tire is dismounted from the axle without a stress point and large tension, the tire needs to be repeatedly shaken outwards by manually matching the forklift, and once the wheel is separated from the axle and falls down due to the fact that the force is too strong, workers can not avoid the tire and can be injured; the workman uses the crowbar to need to keep the stability of crowbar hard, and otherwise the crowbar breaks off the hand easily and causes near workman's injury, and the installation can only be singly leaned on the manpower to prize into the tire with the crowbar and install moreover, will consume great manual work and the workman has the risk of being pressed from both sides the hand by the tire. The existing dismounting machine and wheel side dismounting tool are directed at a tyre machine for a small-sized automobile or a freight car, and have no tyre dismounting device for a large tyre temporarily, so that the limitation is large.

The existing large scraper uses large tires, such as 18.00-25 type tires, 23.5-25 type tires and the like, the replacement period of the large tires is about 1000 hours, and the tires need to be replaced for many times every month. Because the tire is heavy, the total weight of the rim and the tire is about more than 1 ton, the traditional tire replacement method needs to consume 3-4 hours and 5-6 people, and the great potential safety hazard exists in the manual tire replacement process, so that the labor intensity is high, and the shoveling efficiency is influenced; the traditional tire replacement needs fork truck cooperation operation and has the following disadvantages: the forklift needs to be operated by a special person for special equipment, the operation safety risk of the forklift is large, the forklift needs to be commanded by one person, and four persons need to be matched for operation and need 6 persons to be matched for completion. In the traditional tire replacement process, a hammer is required to knock the rim, the rim is easy to deform, and the service life of the rim is greatly reduced. The appearance perfectness of the dismounting device in the prior art is not enough, and only aiming at the specificity of a single tire, the dismounting device is additionally provided with various large-scale wheel rim sleeving tools capable of freely stretching and retracting in the later period, a mechanical universal wheel is changed into a remote control universal wheel, and an intelligent integrated infrared induction system is created. The disassembly of the tires of the large mining vehicles needs to purchase large disassembly and assembly equipment, the equipment cost is high, professional personnel need to be trained for operation, and the investment cost is very high in the period.
