Embodiment 1

[0053] 320-ton heavy-duty truck with 6 wheels in total. The diameter of the rim is 63". The integrated gear seat 4 evenly distributes 8 oil cylinder installation holes 5. The oil cylinder installation holes 5 correspond to the position of the tire bell 7 of the tire 6, and each oil cylinder installation hole 5 is matched with a group of hydraulic dismounting devices. The upper part of the oil cylinder installation hole 5 is provided with a hydraulic cylinder 1, the piston of the hydraulic cylinder 1 is connected with the cylinder ejector rod 2, and the end of the oil cylinder ejector rod 2 is connected with the T-shaped garden post push plate 3. When the tire is removed, the hydraulic cylinder 1 works, The piston rod of the hydraulic cylinder pushes the cylinder push rod 2 and the T-shaped column push plate 3, and the T-shaped column push plate 3 pushes the tire bell 7, which reacts on the integrated gear seat 4, and the integrated gear seat 4 is separated from the tire bell 7 ...

Abstract

The present invention provides a device for hydraulically demounting a tire of a heavy duty vehicle consisting of a tire (6) and a rim (8), wherein, a plurality of oil cylinder installation holes (5) are evenly distributed on the periphery of an end face of an integrated side seat ring (4), a hydraulic oil cylinder (1) is disposed above each of the oil cylinder installation holes (5), the position of each of the oil cylinder installation holes (5) corresponds to the position of bead heel of the tire (7), the integrated side seat ring (4) is disposed on a face of the rim (8) that is in contact with the tire, the hydraulic oil cylinder (1) is provided with an oil cylinder ejecting rod (2), one end of the oil cylinder ejecting rod (2) that is inserted into one of the oil cylinder installation holes (5) is connected to a T-type cylindrical pushing plate (3), and the T-type cylindrical pushing plate (3) is located closely to the bead heel of the tire (7), and each of the oil cylinder installation holes (5) is provided with a dust preventing cover (9). This device has the advantages such as strong demounting power, safe demounting operation, long service life of the rim, and reduced demounting and repair costs.

Description

technical field [0001] The invention belongs to equipment for dismounting tires of trucks, in particular to a device for hydraulically dismounting tires of heavy trucks. Background technique [0002] With the increase of the production scale of various open-pit mines in the world, the loading capacity of ultra-large mining trucks is increasing, some even reaching more than 400 tons, and there is a tendency to gradually increase. As the load increases, the requirements for vehicles, wheels, and rims also increase. For example, in the mining industry all over the world, due to the heavy load of super-large trucks and poor road conditions, the service life of vehicle tires is short, and some new tires are damaged after 2-3 months of operation and need to be replaced. Frequent replacement of tires is an important task in the maintenance of oversized trucks. [0003] The rim, commonly known as the rim, is the part that installs and supports the tire around the wheel. In the pr...
