The invention discloses a spiral pile-forming system and method for matching speed of a main winch with rotating speed of a power head in real time and a rotary drilling rig. The system comprises a first reversing valve, a second reversing valve, a pump I, a pump II, a main winch motor, a power head motor and a controller and further comprises a first rotary knob, a second rotary knob, a first proportional pressure reducing valve and a second proportional pressure reducing valve, wherein the first rotary knob is used for outputting pilot pressure to the first reversing valve by controlling the first proportional pressure reducing valve so as to set the rotating speed of the power head, the second rotary knob is used for setting the multiplying power between the speed of the main winch and the rotating speed of the power head, and the controller is used for controlling the the second proportional pressure reducing valve to output feedback pressure to the pump II according to the rotating speed of the power head and the set multiplying power so as to adjust the speed of the main winch in real time and enable the speed of the main winch to be matched with the rotating speed of the power head in real time. The speed of the main winch and the rotating speed of the power head can be matched in real time, then the manual operation difficulty is reduced, and the working efficiency is improved.

    本发明公开了一种主卷扬速度与动力头转速实时匹配的螺旋成桩系统、方法及旋挖钻机,所述系统包括第一换向阀、第二换向阀、泵一、泵二、主卷扬马达、动力头马达和控制器,还包括:第一旋钮、第二旋钮、第一比例减压阀和第二比例减压阀;所述第一旋钮,用于通过控制第一比例减压阀向第一换向阀输出先导压力,以设定动力头转速,所述第二旋钮,用于设定主卷扬速度与动力头转速之间的倍率,所述控制器,用于根据动力头转速及设定的倍率,控制第二比例减压阀向泵二输出反馈压力,以实时调节主卷扬速度,使主卷扬速度与动力头转速实时匹配。本发明能够实现主卷扬速度与动力头转速实时匹配,降低人为操作难度,提高工作效率。
