The rotary drilling rig comprises an engine, a main pump, a winch motor, the main winch and a controller, the main pump is connected with the engine, the engine drives the main pump to output flow through a coupler, the main pump is used for supplying oil to the winch motor, the winch motor is connected with the main winch, and the controller is connected with the main winch. An electric proportional control valve is arranged in the winch motor, the controller controls the real-time displacement of the winch motor by controlling the input current of the electric proportional control valve, the torque generated by the real-time displacement of the winch motor is converted into the lifting force of the main winch, and the torque generated by the real-time displacement of the winch motor is converted into the lifting force of the main winch by controlling the real-time displacement of the winch motor. And the main winch can obtain the fastest lifting speed meeting the real-time load. According to the self-adaptive control method for the lifting force of the main winch of the rotary drilling rig, the problem that in the prior art, stepless regulation and control of the displacement of the winch motor cannot be achieved can be solved, and the construction efficiency is improved.
本发明提供一种旋挖钻机主卷扬提升力自适应控制方法及旋挖钻机,旋挖钻机包括发动机、主泵、卷扬马达、主卷扬和控制器,主泵与发动机连接,发动机通过联轴器带动主泵输出流量,主泵用于给卷扬马达供油,卷扬马达与主卷扬连接,卷扬马达内设有电比例控制阀,控制器通过控制电比例控制阀的输入电流控制卷扬马达的实时排量,卷扬马达的实时排量所产生的扭矩用以转换成主卷扬的提升力,通过控制卷扬马达的实时排量,使主卷扬能够获得满足实时负载的最快提升速度。本发明的旋挖钻机主卷扬提升力自适应控制方法能够解决现有技术中存在卷扬马达的排量无法实现无级调控的问题,提高施工效率。
