road roller
A road roller is a machine designed for layer-by-layer compaction of non-cohesive, loosely cohesive and cohesive soils and foundations during the construction of embankments, dams, road foundations and other earthworks in the construction of roads, airfields, hydraulic structures, etc.
Device
The working body of the rink is the wheels and / or the roller — a cylinder located instead of the wheel or wheels. With its mass, the roller compresses the compacted substance. The roller has a drive roller, it is supplied with torque from the engine, and a driven one, as a rule, is a guide. The drive of the drive rollers is mechanical for most rollers, but on modern machines it is hydraulic, this is due to an increase in the reliability of hydraulics, the convenience of machine control, which is provided by hydraulic transmission, and the compactness of the hydraulic drive, but mainly because almost all modern rollers are vibratory, with a vibrator hydraulic drive , and the steering system also uses a hydraulic drive, so when using a hydraulic drive and on wheels, design optimization is achieved.
Types of skating rinks
According to the method of movement , rollers are divided into trailed and self-propelled.
- Trailer rollers use the energy of a tractor (human, horse, tractor or other vehicle) for movement.
- Self-propelled rollers are equipped with their own engine that drives the wheels or rollers.
According to the number of axles, rollers are divided into one-, two- and three-axle.
By the number of rollers for one, two and three rollers.
According to the type of impact on the compacted material, the rollers are divided into static and vibration.
- Static rollers compact the soil by compressing it with their own weight. This type of roller was once the most common but has now become rare, having been superseded by the more compact and lighter vibratory rollers. At the same time, the need for static rollers remains, as they can be used for compaction where vibration is unacceptable. Also, static rollers leave a smoother surface behind, and therefore they are used where this requirement is mandatory.
- Vibratory rollers are equipped with a special device — a vibrator, which is a rotating load with a center of mass shifted relative to the axis of rotation, which creates powerful vibration. Due to vibration at a significantly lower weight compared to a static roller, the vibratory roller has a greater compacting effect. However, the vibratory roller does not allow creating a perfectly even layer, leaving behind “waves” on the compacted material, and its dynamic loads can damage the basis of the compacted surface.
According to the type of rollers, rollers are: with smooth rollers, cam, lattice, pneumatic wheels:
- Rollers with smooth rollers are machines with smooth wide metal wheels. It is usually used for asphalt paving, due to the fact that it gives a flat area at the exit;
- Cam rollers are distinguished by the fact that they are covered with cams — small protrusions. When rolling, the cams penetrate the soil, break up clods and mix it up, improving compaction. Effective for working with loose soil;
- The lattice rollers are equipped with rollers with a lattice surface. It is used for ramming various soils. When passing through heterogeneous soil, large lumps are crushed, which increases compaction;
- Pneumatic rollers instead of rollers are equipped with wheels assembled in packages with pneumatic tires. Due to the presence of gaps between the pneumatic tires, from which unsealed strips remain during operation, the tires are set so that these gaps at the front and rear wheels do not coincide;
- Combined rollers are a combination of the above rollers, for example, the front roller is smooth, and the rear roller is pneumatic).
In addition, rollers are divided by weight from manual (less than 1 ton) to heavy (more than 16 tons) and even super-heavy (weighing up to 100 tons or more).
For soil, the depth of ramming can, for various structures, vary from 20–30 cm to 150–160 cm.
Modern road rollers are capable of speeds up to 14 km/h, but for most the maximum speed is 2-5 km/h.
