Large offshore hydraulic pile hammer
The invention relates to the technical field of engineering machinery, in particular to a large offshore hydraulic pile hammer which comprises a hammer shell and a hammer core located in the hammer shell, at least one hydraulic assembly capable of promoting the hammer core to move in the axial direction of the hammer shell is arranged between the hammer shell and the hammer core, and pile caps are connected to the bottom of the hammer shell and comprise the upper pile cap and the lower pile cap. A driving-replacing block is arranged in the upper pile cap, the hydraulic assembly can drive the hammer core to hit the driving-replacing block, an expanding ring is arranged at the bottom of the driving-replacing block in the upper pile cap, a first mounting groove for mounting the driving-replacing block is formed in the top of the expanding ring, a first mounting cavity is formed by an inner cavity of the expanding ring and the driving-replacing block, and a second mounting cavity is formed by the bottom face of the expanding ring and the inner wall of the lower pile cap. The hydraulic pile hammer has the beneficial effects that potential safety hazards can be reduced, the service life of the pile hammer is prolonged, and meanwhile the construction efficiency is improved.
本发明涉及工程机械技术领域，特别涉及一种大型海上液压打桩锤，包括锤壳以及位于锤壳内的锤芯，锤壳以及锤芯之间设有能够促使锤芯沿锤壳轴向位移的至少一组液压组件，锤壳底部连接有桩帽，桩帽包括上桩帽以及下桩帽，上桩帽内设有替打块，液压组件能够驱动锤芯击打替打块，上桩帽内位于替打块底部设有扩径环，扩径环顶部设有供替打块安装的第一安装槽，扩径环的内腔与替打块形成有第一安装腔，扩径环的底面与下桩帽内壁形成有第二安装腔，第二安装腔直径大于第一安装腔的直径，本发明的有益效果为：提供一种能够减少安全隐患，增大打桩锤使用寿命同时提高施工效率的液压打桩锤。
