The invention relates to a turnover hydraulic control device, and belongs to a hydraulic system. The turnover hydraulic control device is characterized by comprising a hydraulic power device, a plurality of groups of hydraulic pressure overturning oil cylinders, a swinging oil cylinder, a hydraulic motor, and electromagnetic reversing valves each of which is connected with the corresponding hydraulic pressure overturning oil cylinder, wherein a high-pressure hydraulic pipe and a reflux hydraulic pipe of the hydraulic power device are connected with the electromagnetic reversing valves; and theelectromagnetic reversing valves are plugged in the corresponding overturning oil cylinders or the swinging oil cylinder. The turnover hydraulic control device disclosed by the invention has the advantages that oil return is controlled by a proportional flow control valve, so that the action of 180-degree overturning of the swinging oil cylinder is smooth; in the overturning process of the oil cylinder, a part of impact force is offset by a counterbalance valve, and the oil cylinder is smoothly overturned to the terminal through the proportional flow control valve, impact is avoided, and damage to building block products is avoided; and equipment is driven by the hydraulic system to move to overturn the formed materials to the ground, and the formed materials can be moved to the next position for reforming and overturning once again, so that continuous operation can be realized, and overturning carrying speed is increased.
本发明涉及一种翻转机液压控制装置,属于一种液压系统。本发明采用的技术方案是:包括液压动力装置、多组翻转翻转油缸、摆动油缸、液压马达、与各液压翻转油缸相连的电磁换向阀,液压动力装置的高压液压管和回流液压管分别接入电磁换向阀,电磁换向阀接入对应的翻转油缸或摆动油缸。本发明的优点在于:采用比例调速阀控制回油,实现摆动油缸180度翻转平稳动作,在油缸翻转过程中抗衡阀抵消部分冲击力,通过比例调速阀平稳翻至终点,避免冲击,避免砌块产品的损坏。液压系统带动设备移动,把成型好的材料翻转到地上,可移动到下一个位置再成型再翻转,能够连续化作业,提高翻转搬运速度。
