Abstract

The invention discloses an automatic cleaning device for a tire tread stone of a rubber-tyred vehicle, which is arranged on a frame of the rubber-tyred vehicle and corresponds to the tire tread position of the tire. The mounting bracket is fixed on the frame of the rubber-tyred car. The cleaning mechanism comprises a movable arm and a stone remover, one end of the movable arm is hinged with the mounting bracket, the other end of the movable arm is connected with the stone remover, and a pressure sensor acting on the tread of the tire is arranged on the stone remover. The driving mechanism is in transmission connection with the movable arm and is used for driving the movable arm to swing around the hinge point so as to adjust the fitting angle and the pressure of the stone remover and the tire tread. The invention can adjust the position and pressure of the cleaning mechanism in real time, can keep the cleaning teeth in an optimal working state no matter whether the tire is worn, the load is changed or the sizes of stones are different, improves the cleaning effect, and can further improve the cleaning effect of the stone clamping through the mutual matching of the multi-tooth structure and the air nozzle.

Description

Automatic cleaning device for rubber-tyred tire tread stone clamping Technical Field The invention belongs to the technical field of vehicle auxiliary equipment, and particularly relates to an automatic cleaning device for rubber-tyred tire tread stone clamping. Background Rubber-tyred vehicles (such as mining dump trucks, loaders, beam-transporting vehicles and the like) generally operate in severe environments where broken stones are spread over, and tread pattern grooves of tires are extremely easy to embed and block sharp stones. The stones are strongly squeezed and rubbed in the running process of the vehicle, so that not only can the tire tread be pierced to cause air leakage, but also the tire body cord can be damaged, and the service life of the tire is greatly shortened. In addition, the high-speed rotating tires throw away the stone and may hit the rear vehicles or roadside personnel, causing serious property loss and safety accidents. At present, most common treatment modes are manual cleaning, namely, a driver or a maintainer uses tools such as a crowbar to manually remove the stone. The mode is high in labor intensity and low in efficiency, is difficult to carry out in the running process of the vehicle, and cannot be cleaned in real time. There are also some stone removing devices on the market, such as patent CN206297352U discloses a stone removing device for a heavy equipment tire, but it is mainly aimed at removing the stone clamped between the tires, and the problem of stone clamped in the tread pattern of the tire is not solved.
