Concrete pumping equipment and control method thereof
The invention relates to concrete pumping equipment and a control method thereof. The concrete pumping equipment comprises a distribution valve, a first conveying cylinder, a first hydraulic cylinder, a second conveying cylinder, a second hydraulic cylinder, a third hydraulic cylinder, a hydraulic pump, an overflow valve set, a first detection part and a controller, and a first concrete piston is arranged in the first conveying cylinder; the first hydraulic cylinder is configured to drive the first concrete piston to reciprocate in the first conveying cylinder; a second concrete piston is arranged in the second conveying cylinder, and the second conveying cylinder and the first conveying cylinder alternately suck materials and alternately push the materials to an inlet of the distribution valve; the second hydraulic cylinder is configured to drive the second concrete piston to reciprocate in the second conveying cylinder; the third hydraulic cylinder drives the distribution valve to swing, so that an inlet of the distribution valve alternately communicates with the first conveying cylinder and the second conveying cylinder; the hydraulic pump configured to provide hydraulic fluid to the first hydraulic cylinder, the second hydraulic cylinder, and the third hydraulic cylinder; the overflow valve set communicates with the hydraulic pump; the first detection part is configured to detect whether the movement direction of a piston rod of the first hydraulic cylinder is switched or not; and the controller is in correspondingly signal connection with the overflow valve set and the first detection part, so that the overflow pressure of the overflow valve set is adjusted from the first pressure P1 to the second pressure P2 when the movement direction of the piston rod of the first hydraulic cylinder is switched, and the first pressure P1 is larger than the second pressure P2.
本发明涉及一种混凝土泵送设备及其控制方法，混凝土泵送设备包括：分配阀；第一输送缸，其内设有第一砼活塞；第一液压缸，配置成驱动第一砼活塞在第一输送缸内往复移动；第二输送缸，其内设有第二砼活塞，与第一输送缸交替地抽吸物料并交替地向分配阀的进口推送物料；第二液压缸，配置成驱动第二砼活塞在第二输送缸内往复移动；第三液压缸，驱动分配阀摆动，以使分配阀的进口交替地与第一输送缸和第二输送缸连通；液压泵，配置成为第一液压缸、第二液压缸和第三液压缸提供液压流体；溢流阀组，与液压泵连通；第一检测部件，配置成检测第一液压缸的活塞杆的运动方向是否切换；控制器，与溢流阀组和第一检测部件分别信号连接，以在第一液压缸的活塞杆的运动方向切换时将溢流阀组的溢流压力由第一压力P1调整至第二压力P2，其中第一压力P1＞第二压力P2。
