The invention discloses a pile pressing device. A pressing plate is included, the pressing plate is connected with a plurality of sets of symmetrically-arranged ropes, and the ropes are wound around winding shafts; gears are connected to the end portions of the winding shafts and engaged with racks, the racks are connected with oil cylinders, and the oil cylinders communicate with hydraulic pumpsthrough communicating pipes. Displacement sensors are mounted on the oil cylinders; and an electric adjusting valve and a flow meter are arranged on each communicating pipe. According to the pile pressing device, resultant force is formed through the multiple oil cylinders to press a pile downwards, it is guaranteed that the downward pressure of the oil cylinders is equal through the displacementsensors and the electric adjusting valves, and therefore the possibility that the pile is pressed to be deviated is effectively prevented.
本发明公开了一种压桩装置，包括压板，压板连接有若干组对称设置的绳索，绳索缠绕在缠绕轴上；缠绕轴端部连接有齿轮，齿轮啮合有齿条，齿条连接有油缸，油缸通过连通管连通有液压泵；油缸上安装有位移传感器；连通管上安装有电调节阀和流量流速计。本发明通过多个油缸形成合力对桩柱进行下压，且通过位移传感器和电调节阀保证了个油缸下压力的相等，从而有效的防止了将桩柱压偏的可能性。
