Abstract

The invention discloses a small pile foundation vibration resistance reduction type efficient pile pulling device for hydraulic engineering construction, and particularly relates to the field of hydraulic engineering. The small pile foundation vibration resistance reduction type efficient pile pulling device comprises a supporting vertical frame, a pile pulling driving mechanism and a driving mechanism, wherein the pile pulling driving mechanism is fixedly arranged on the top surface of the supporting vertical frame through a screw rod, the driving mechanism is fixedly arranged on one side of the supporting vertical frame, a control panel is fixedly arranged on the surface of the pile pulling driving mechanism, a driving screw rod is movably arranged on the surfaces of the pile pulling driving mechanism and the supporting vertical frame, and the bottom of the driving screw rod is rotationally connected with a movable pile pulling foundation table in a sleeved mode. According to the scheme, the pile pulling device adopts a pile head keeping mechanism and a vibration clamping plate structure, the pile head keeping mechanism and the vibration clamping plate are used for carrying out surrounding type clamping structure on a pile sinking pile head, an annular structure is formed on the periphery of the pile head by utilizing the pile head keeping mechanism, the distance between the vibration clamping plates is adjusted through thread engagement with a clamping screw rod so as to clamp the pile head, the pile head keeping mechanism and the vibration clamping plate structure can be matched with pile heads with different shapes and sizes, and the practicability of the pile pulling device is improved.

本发明公开了一种水利工程施工用小型桩基振动减阻型高效拔桩设备，具体涉及水利工程领域，包括支撑立架、拔桩驱动机构和驱动机构，拔桩驱动机构通过螺杆固定安装于支撑立架的顶面，驱动机构固定安装于支撑立架的一侧，拔桩驱动机构的表面固定安装有控制面板，拔桩驱动机构和支撑立架的表面活动安装有驱动螺杆，驱动螺杆的底部转动套接有运动拔桩基台。上述方案，该拔桩设备采用桩头保持机构和振动夹板结构，利用桩头保持机构和振动夹板对沉桩桩头进行环抱式夹持结构，利用桩头保持机构在桩头外周形成环形结构并通过与夹持螺杆的螺纹啮合调节振动夹板之间间距对桩头进行夹持，可适配不同形状大小桩头，提高该拔桩设备的实用性。
