The invention relates to the technical field of pile drivers, in particular to a hydraulic pile driver which comprises a pile frame, a hydraulic cylinder and a pile hammer, the hydraulic cylinder is mounted on the pile frame, the pile hammer is fixed to a piston rod of the hydraulic cylinder, and the hydraulic pile driver further comprises a grabbing mechanism located under the pile hammer. The grabbing mechanism comprises a turning plate which is hinged to the pile frame and can turn over vertically, a pushing device for driving the turning plate to turn over and two clamping plates which are symmetrically arranged on one side of the turning plate and are of a C-shaped structure, sliding blocks are arranged on the clamping plates, sliding holes matched with the sliding blocks are formed in the turning plate in the width direction, and the two sliding blocks are connected through a double-end lead screw. By arranging the clamping mechanism comprising the turning plate, the pushing device, the clamping plate, the sliding block, the sliding hole and the double-end lead screw, before piling, a pile body horizontally placed on the ground can be clamped through the clamping plate on the turning plate, and vertical overturning of the pile body is achieved through the pushing device, so that the pile body can be easily and vertically placed; and the pile body can be conveniently placed before piling, and the pile body stability during piling is improved.
本发明涉及打桩机技术领域，具体为一种液压打桩机，包括桩架、液压缸和桩锤，液压缸安装在桩架上，桩锤与液压缸的活塞杆固定，液压打桩机还包括位于桩锤正下方的抓取机构，抓取机构包括与桩架铰接且可垂直翻转的翻板、驱动翻板翻转的推动装置以及对称设于翻板一侧的两块C型结构的夹板，夹板上设有滑块，翻板上沿宽度方向开有与滑块相适配的滑孔，两滑块之间通过双头丝杆连接。本发明通过设置包含翻板、推动装置、夹板、滑块、滑孔和双头丝杆的夹取机构，打桩前，可通过翻板上的夹板对水平放置在地面上的桩体进行夹取，并利用推动装置实现桩体的垂直翻转，使得桩体能够被轻易的竖直放置，方便打桩前的桩体放置以及打桩时的桩体稳定性。
