Modularized walking type excavator walking control system and control method
According to the modular walking control system and method for the walking type excavator, an electric proportional pressure reducing valve is combined with a hydraulic control proportional motor, and the hydraulic control proportional motor is controlled according to the relation between the displacement of the hydraulic control proportional motor and the control pressure and the corresponding relation between the pressure of the electric proportional pressure reducing valve and the current; the displacement of a left motor and the displacement of a right motor are set through a displayer interface, a controller calculates hydraulic control pressure according to the relation between the displacement of the motors and a pressure characteristic curve, control current is calculated and a current signal is sent out according to the corresponding relation between the pressure of the electric proportional valve and a current characteristic curve, and the displacement of the motors needs to be set; during operation, displacement switching is achieved through a control panel switching button, speed switching is carried out, and engine power is fully utilized. The displacement setting of the motors can be quickly realized as required, the operation is simple, the pressure of a plurality of groups of electric proportional pressure reducing valves can be set as required, the displacement setting of each motor is independently controlled, and the speed consistency is well ensured; and intelligent and remote operation requirements are met through an electro-hydraulic split type control mode, so that the working efficiency is improved.
