Classification of rollers
The front wheel frame is hinged with the frame to reduce the unusual body sway of the road surface. The rear wheel and the frame are rigidly connected. Hydraulic control, hydraulic cylinder control steering. The front and rear grinding wheels are equipped with scraper to remove the adhesive on the roller. A sprinkler system is also provided for compacting the asphalt pavement by sprinkling the wheel to prevent adhesion of the asphalt mixture. To increase the force, but also in the grinding wheel with iron, sand, water and so on, increase the weight. The main technical parameters of steel wheeled roller are weight and line pressure. In 80s, all kinds of steel wheeled roller, machine weight range is about two wheeled roller 2~13 tons, three wheeled roller 1~15 tons, according to the requirements can be pressurized 1~3 tons, three axle roller press 13~14 tons, the pressure is 18~19 tons after weight. The roller is made of pneumatic tyres, usually with 3~5 front wheels and 4~6 rear wheels.
The utility model is suitable for various compaction operations with the gravity action of the machine itself, so that the compacted layer is permanently deformed and compacted. It is divided into two types: steel wheel type and tyre type. Grinding wheel grinding, grinding groove structure light and kneading etc.. Light milling is the most common and is mainly used for pavement surface compaction. With mechanical or hydraulic transmission, the utility model can concentrate the compacted part of the protruding part, and has high compaction and smoothness, and is suitable for the compaction operation of the asphalt pavement. According to the layout of the axle, there are single shaft, single wheel, double shaft, double shaft, three wheel and three axle, three wheel and so on. The internal combustion engine is powered by mechanical or hydraulic transmission. General front wheel steering, good maneuverability, rear wheel drive. In order to improve the steering and rolling performance, the articulated steering structure and all wheel drive should be adopted.
