Rubber-tyred road roller and oil injection system thereof

Abstract

The invention discloses an oil injection system. The oil injection system comprises a liquid collecting device, a pump device and a plurality of spray heads; the liquid collecting device is used for storing oil medium; the pump device is used for pumping the oil medium form the liquid collecting device and outputting the oil medium to a system pressure circuit, the spray heads are respectively arranged corresponding to the tyres of a rubber-tyred road roller and are fixedly arranged on the frame of the rubber-tyred road roller; and the liquid inlet of each spray head is respectively communicated with the system pressure circuit, and the oil medium is sprayed onto corresponding surfaces of the tyres through the spray heads. The invention establishes work pressure of the oil medium in a system pipeline by starting up the pump unit, and the formed oil medium is output to each spray head. Thus, under the action of the pressure, the oil medium is evenly sprayed on the surfaces of the tyres in a foggy form through the spray heads; with the travelling of the road roller, the oil medium exists between the surfaces of the tyres and the road surface all the time, thus not only ensuring the anti-blocking property of the surfaces of the tyres but also effectively controlling the manufacturing cost; and on the basis, the invention also provides a rubber-tyred road roller with the oil injection system.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an oil injection system and a tire-type road roller using the oil injection system. Background technique [0002] As we all know, road rollers are widely used in road construction, embankment and dam construction, etc., which use the rolling effect of rollers to make soil, roadbed cushion and pavement pavement dense to meet different construction requirements. Generally speaking, according to the compaction principle of the road roller, it can be roughly divided into two categories: static pressure road roller and vibratory road roller. Among them, under the action of the gravity of the machine itself, the static pressure road roller makes the layer to be rolled permanently deformed and compacted. The static pressure road roller is mainly divided into two types: steel wheel type and tire type. [0003] The tire-type road roller uses pneumatic tires to compact the p...

Problems solved by technology

Among them, the anti-adhesion effect of the infrared heating device is better, but the cost is too high (about 100,000 yuan or more per set); compared with the infrared padding device, the cost of the sprinkler system is lower. Composed of pump, sprinkler head and corresponding pipelines, it avoids sticking asphalt by sprinkling water evenly on the surface of the smooth tire, but because the sprinkling process is difficult to control, the steam film on the tire surface is not enough if the amount of water is small, and the asphalt is easy to stick and prevent sticking The effect is not ideal; too much water will easily lead to rapid cooling of the asphalt, resulting in segregation, which cannot meet the requirements of the construction technology of the grade pavement
