Description

technical field [0001] The invention relates to a construction engineering machine, in particular to a mechanical device for adjusting the vibration amplitude of an intelligent vibratory road roller. Background technique [0002] At present, domestic and foreign vibratory rollers use manual control of amplitude change. The common way to automatically adjust the amplitude is to change the rotation direction of the vibration shaft of the vibratory roller. Only two levels of amplitude adjustment can be realized. In the process of road and site compaction construction, the soil quality, base layer and sub-base layer of construction sites in different regions are different, and the working conditions of the road roller are more complicated. In the construction of expressways and high-grade, high-quality sites, construction is required The device has higher performance. The existing dual-amplitude rollers that are commonly used cannot meet the requirements of many different worki...

Problems solved by technology

Compared with the stepped amplitude modulation mechanism, the stepless amplitude modulation mechanism is much more complicated and difficult to realize. A relatively mature stepless amplitude modulation system has two eccentric shafts, one vibration shaft is driven by a hydraulic motor, and the other vibration shaft is driven by a hydraulic motor. Driven by the gear sets on the two eccentric shafts, the positional relationship between the two eccentric shafts can be adjusted through the drive of the hydraulic cylinder. The hydraulic cylinder is controlled by the electro-hydraulic proportional servo valve. The control system controls the pulse width according to the amplitude command given by the compaction meter Modulation, control the on-off time of the electro-hydraulic proportional servo valve, control the flow of hydraulic oil in the hydraulic cylinder, adjust the position of the hydraulic cylinder, and then adjust the relative position of the two eccentric shafts to achieve the purpose of adjusting the amplitude, but the electro-hydraulic proportional servo used The cost of the valve is relatively high, which in turn causes the engineering cost of the intelligent road roller to be relatively high, which affects the popularization and use
