Hydraulic vibratory hammer starting control system and implementation method thereof
The invention discloses a hydraulic vibratory hammer starting control system and a control method. The system comprises an upper computer and a signal converter; the upper computer is used for outputting a voltage control signal; the voltage control signal comprises a slope type voltage control signal or a curve type voltage control signal; the signal converter is used for converting the voltage control signal into a current signal; the upper computer is connected with the signal converter; the signal converter is connected with an electro-hydraulic proportional valve; the electro-hydraulic proportional valve is connected with an oil pump; and the oil pump is connected with a vibratory hammer body through an oil pipe. The flow of the oil pump is controlled by controlling the valve opening degree of the electro-hydraulic proportional valve, so that the flow of the oil pump is slowly increased, a hydraulic vibratory hammer is stably started through hydraulic power transmitted by the oil pump, hydraulic impact is eliminated or reduced, an original mechanical structure of a hydraulic control system of the hydraulic vibratory hammer does not need to be changed, the purpose of eliminating or weakening strong vibration of the hydraulic vibratory hammer in the starting process can be achieved, and the system can be widely applied to the technical field of hydraulic vibratory hammers.
本发明公开一种液压振动锤起动控制系统及其控制方法，系统包括：上位机，用于输出电压控制信号，电压控制信号包括斜坡式电压控制信号或曲线式电压控制信号；信号转换器，用于将电压控制信号转换为电流信号；上位机与信号转换器连接，信号转换器与电液比例阀连接，电液比例阀与油泵连接，油泵通过油管与振动锤体连接。本发明通过控制电液比例阀的阀门开度来控制油泵的流量，使得油泵的流量缓慢增加，使得液压振动锤通过油泵传递的液压动力实现平稳起动，从而消除或降低液压冲击，无须改变原有的液压振动锤液压控制系统机械结构，即可达到消除或削弱液压振动锤在起动过程中的强烈振动的目的，可广泛应用于液压振动锤技术领域。
