Concrete pumping equipment and reversing control method for pumping oil cylinder of same

Abstract

The invention provides concrete pumping equipment and a reversing control method for a pumping oil cylinder of the same. The reversing control method comprises the following steps of: acquiring operating condition parameters of the oil cylinder in real time, and determining a current operating condition according to the operating condition parameters so as to determine a corresponding reversing position of the oil cylinder according to the current operating condition; and detecting a piston position of the oil cylinder in real time and controlling the reversing of the oil cylinder when the piston position of the oil cylinder reaches the reversing position. By the reversing control method for the pumping oil cylinder of the concrete pumping equipment, the actual operating condition can be determined according to the detected operating condition parameters, so the reversing position, corresponding to the actual operating condition, of the oil cylinder is determined, and the reversing ofthe oil cylinder is controlled according to the actual operating condition; therefore, optimal stroke of the oil cylinder under any operating conditions of a concrete pump can be ensured, the pumpingefficiency is the highest.

Description
