Hydraulic control rotation device of static pile press and control method thereof
The invention discloses a hydraulic control rotation device of a static pile press and a control method thereof. The rotation device is characterized in that a brake unit is mounted on the right sidesurface of a hydraulic motor, a bearing seat is mounted on the right side surface of a three-stage planetary gear train, a transition flange is mounted at the bottom of the left side of the hydraulicmotor, and a valve seat is mounted on the bottom surface of the transition flange. The left side face and the right side face of the valve seat are each provided with a first balance valve set, a first one-way valve, a fourth one-way valve and a second balance valve set, the second one-way valves are installed on the front side surface of the valve seat, the third one-way valves are installed on the rear side surface of the valve seat, a shuttle valve is installed in the valve seat, and a throttle valve is installed at the bottom of the valve seat. The device operates stably and reliably. In the rotation process, the constant speed can be always kept by means of the effect of a balance valve all the time, accelerated impact generated by inertia of the weight is avoided, meanwhile, in the braking process, a brake is slowly closed, the stable buffering period is provided for the rotation device, a whole static pile press platform is protected, and the hydraulic motor and the hydraulic brake are also protected.
本发明公开了一种静压桩机液控回转装置及其控制方法，其特征在于：所述的制动器单元安装在液压马达右侧面，轴承座安装在三级行星轮系右侧面上，过渡法兰安装在液压马达左侧底部，阀座安装在过渡法兰的底面上，阀座左侧面和右侧面上都安装有第一平衡阀组、第一单向阀、第四单向阀和第二平衡阀组，第二单向阀安装在阀座的前侧面上，第三单向阀安装在阀座的后侧面上，梭阀安装在阀座内，节流阀安装在阀座底部。本发明运行稳定可靠，回转过程中始终靠平衡阀的作用始终保持匀速，而不会因为重物的惯性产生加速冲击，同时制动时制动器缓慢关闭，给予回转装置稳定的缓冲期，不仅保护了整个静压桩机平台，也保护了液压马达和液压制动器。
