Description

Surface mine engineering vehicle wheel dismounting device Technical Field The utility model relates to the technical field of wheel dismounting equipment, in particular to a wheel dismounting device for an open pit mine engineering vehicle. Background In the mine industry, the surface mine engineering vehicle accounts for 80% of the total equipment, and maintenance work of related components such as wheel edge oil leakage, oil seal replacement, brake pad replacement, tire abrasion and skin breaking and the like all need to be carried out on the dumper tire after the dumper tire is removed, so that the number of daily maintenance dumpers is large. The existing process for disassembling the wheels of the surface mine engineering vehicle comprises the steps of firstly disassembling the fixing nuts of the wheels by adopting a screwdriver, then prying the wheels out of a vehicle body by adopting an iron stick, then conveying the wheels to a repair shop to separate the tires from the wheel hub by adopting a tire removing machine, or conveying the tires to a beside wheel hub tire disassembling device (such as a special tool for disassembling the tire of the scrapped automobile with the application number of 202010300945.0) to separate the tires from the wheel hub. Then, for the disassembly of the wheels of the surface mine engineering vehicle, two processes are specifically performed, namely, the wheels are disassembled from the vehicle body firstly, and the wheels (tires and hubs) are separated, and obviously, the tires and the hubs are separated by the convenient disassembly device, and the wheels are generally disassembled from the vehicle body by manual work through iron sticks, so that long-time manpower is required, the efficiency is low, and the hubs and the tire surfaces are easy to damage. Disclosure of utility model The technical problem to be solved by the utility model is to overcome the defects of the prior art, and provide the wheel dismounting device for the surface mine engineering vehicle, which is time-saving, labor-saving, high in efficiency and not easy to damage wheels. In order to solve the technical problems, the utility model adopts the following technical scheme: The utility model provides an opencast mine engineering vehicle wheel dismounting device, includes bears frame and landing leg, the front end bottom that bears the frame is equipped with removes the wheel, front end top is equipped with the sled board, the rear end that bears the frame is equipped with push-and-pull handle, the top of landing leg is connected with the middle part that bears the frame, the bottom is equipped with the supporting wheel, the upper surface that bears the frame is equipped with the place platform that is used for holding the wheel. As a further improvement of the above technical scheme: The middle part of the placing platform is provided with a limiting column for being inserted into the middle part of the wheel to limit.
