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

technical field [0001] The invention relates to the field of concrete pumping, and more specifically, to a concrete pumping equipment and a method for controlling the reversing of a pumping oil cylinder thereof. Background technique [0002] like Figure 1-2 As shown, the concrete pumping mechanism in the prior art includes a pumping unit 1, a concrete cylinder 6, a concrete cylinder 7, a hopper 8 and an S valve 9; wherein, the pumping unit 1 includes an oil pump 2, an oil pump 13, a valve group 3, Valve group 15 , oil cylinder 4 , oil cylinder 5 , oil cylinder 16 , oil cylinder 17 , signal detection device 10 and signal detection device 11 ; the pumping unit 1 also includes a control unit 12 and an accumulator 14 . The working process of the concrete pumping mechanism is as follows: oil cylinder 4 and oil cylinder 5 are driven by oil pump 2, and the pistons of concrete cylinder 6 and concrete cylinder 7 reciprocate alternately under the control of oil cylinder 4 and oil cyl...
