Abstract

The invention discloses a jump vibration prevention control system and a jump vibration prevention control method of a vibration road roller. The control system comprises a start switch, a vibration switch, a controller, a pressure sensor and a buzzer. One or multiple thresholds are set; after the road roller is started, the jump vibration prevention control system is used to monitor the pressure of a vibration hydraulic system; according to the threshold range of the pressure, the methods of vibration frequent reduction and amplitude reduction are respectively used to control jump vibration prevention till the pressure of the vibration hydraulic system reaches the maximum threshold, so as to stop the vibration. According to the control system and method, the jump vibration of a vibration wheel can be prevented, so as to avoid over pressing of foundation, road surface or other pressed material to cause resource waste.

Description

technical field

[0001] The invention relates to an anti-jump control system and a control method of a vibratory road roller, belonging to the technical field of engineering machinery. Background technique

[0002] At present, when domestic vibratory rollers perform compaction operations on asphalt pavement, when the compaction degree is close to the critical point of the required compaction degree, there is a high-risk area, and there is a high risk of over-compaction in this high-risk area. However, when judging whether the road surface requirements are met, since there is no standard to guide the user's operation, the operator mostly relies on the experience of road compaction. In order to prevent undervoltage, the operator will basically compact several times, which will increase The probability of overpressure on the road surface is reduced. Excessive compaction will cause the vibrating wheel to jump off the ground, loosen the compacted material, or crush the compressed...
