The principle of a roller is actually very simple. The vibrating shaft rotates like the wheel shaft of a regular car, and there are eccentric blocks on the vibrating shaft. Assuming that the shaft is not a uniformly symmetrical cylindrical shape, but has a large protruding position, this protruding position will generate different forces on the shaft when turned above and below, which can cause the vibration of the vibrating shaft of a small roller. What exactly is it? Below is an analysis by the rental manufacturer of Jinan road rollers for you:
1、 Principle of force action
The force acting principle of a road roller is to compact the soil through gravity and make the road surface flat. Usually, a roller generates direct pressure on the soil or road surface through the weight of its body.
2、 Principle of Vibration Action
Secondly, the vibration principle of the roller is to help the soil or road surface become more compact and sturdy through the vibration of the machine body, in order to achieve better compaction effect. The key to the principle of vibration action lies in the vibrating shaft, which excites the entire body of the roller to vibrate downwards and forwards, thereby compacting the soil and road surface through compaction and leveling. The frequency and amplitude of vibration have a significant impact on the compaction effect, and adjustments need to be made based on different soil properties, thicknesses, and compaction requirements.
3、 Rolling action principle
The roller also has a rolling action principle, which applies pressure to the soil through the rolling of the tires to make it compact and make the road surface flat. The rolling effect is only applicable to asphalt pavement, and its principle is that the roller pulverizes and flips the road surface through the rolling of tires, resulting in compression and further improving the compactness of the road surface.
1. Machine inspection: Before using the road roller, sufficient machine inspection must be carried out to ensure that all parts of the machine are in good condition, especially the tires, fuel tank, and engine parts of the machine, which must be well maintained and maintained.
2. Turn on the machine: Turn on the power switch of the machine and turn on auxiliary equipment such as air conditioning and fans.
Adjusting the vibrator: Select the vibrator or vibration method as needed, adjust the vibration frequency and amplitude to achieve optimal compaction effect.
3. Start work: Drive the machine into the work area and start compacting the road surface or geotechnical materials according to the predetermined route and speed.
4. Monitoring work: During the work process, it is necessary to constantly monitor the compaction effect and adjust the frequency and amplitude of the vibrator in a timely manner to ensure that the compaction effect of the road surface or geotechnical materials meets the requirements.
5. End of work: After completing the compaction operation, drive the machine back to the garage or parking area for maintenance and upkeep of the machine.
The working principle of a road roller is to achieve compaction and leveling of soil or road surface through various modes of gravity, vibration, and rolling, and make it more compact, sturdy, and flat. Its principle is an indispensable key link for earthwork engineering. For more related content, come to our website http://www.ycgjglcl.com consulting service
