Abstract

The invention relates to a wheel type polishing machine, relates to a polishing machine, specifically relates to a polishing machine for laboratory simulation of polishing of an automobile tire on the highway road surface, and is used for solving the problems that the current accelerated polishing machine can just polish the surface of coarse aggregates used by the road surface, but cannot polish the mixture used by the road surface. A first motor is in transmission connection with a first reducer, the first reducer is in transmission connection with a main shaft, the main shaft is fixedly connected with a wheel axle, the main shaft and the wheel axle are verticality arranged, and tires are respectively installed at two ends of the wheel axle; and the output shaft of a second motor is in transmission connection with the input shaft of a second reducer, the second reducer is in transmission connection with a second wheel, the second wheel is in transmission connection with a third wheel, a fourth wheel is in transmission connection with a fifth wheel, first stoppers are respectively installed on the upper end surface and the lower end surface of a first chain, and second stoppers are installed on the upper end surface and the lower end surface of a second chain respectively. The wheel type polishing machine can be used for laboratory simulation of polishing of the automobile tire on the highway road surface; and the abrasion resistance of the mixture can be evaluated according to the measured polishing value of the mixture.

Description

technical field [0001] The invention relates to a polishing machine, in particular to a polishing machine for indoor simulating automobile tires polishing road surfaces. Background technique [0002] The anti-slip performance of the road surface is inseparable from the anti-grinding performance of the aggregates and mixtures used in the surface layer. With the continuous polishing of the traffic vehicles on the road surface, the aggregates on the pavement surface gradually become smoother, and the pavement structure becomes more dense. As a result, the anti-skid ability of the road surface is reduced, which directly affects driving safety. The polishing performance of aggregates in my country's current highway codes is mainly the coarse aggregate polishing value test (T0321-2005) in the "Highway Engineering Aggregate Test Regulations" (JTG E42-2005). This method mainly uses an accelerated polishing machine to polish the surface of the coarse aggregate, and uses a pendulum f...
