Pile gripper of vibrating pile hammer with internal supporting type clamping structure and using method of pile gripper
The invention relates to the technical field of building foundation engineering, in particular to a pile gripper of a vibrating pile hammer with an internal supporting type clamping structure. The clamping structure comprises a sleeve and a clamping oil cylinder mounted in the sleeve, and a plurality of wedge-shaped pushing blocks are connected with the bottom of the oil cylinder; and the oil cylinder drives the wedge-shaped pushing blocks to move up and down in the axial direction of the sleeve, a plurality of wedge-shaped clamping blocks are matched with the wedge-shaped pushing blocks in position, the matching faces are inclined faces, and the wedge-shaped pushing blocks move up and down in the axial direction, so that the wedge-shaped clamping blocks move in the radial direction of thesleeve and abut against the inner wall of a pile pipe to be clamped after being unfolded outwards. The pile gripper of the vibrating pile hammer with the internal supporting type clamping structure can be embedded into a tubular pile, is propped open and clamps the tubular pile from inside to outside, the problem that a traditional pile clamping device cannot sink into the ground is perfectly solved, the clamping force is larger, and pile sinking operation is facilitated.
本发明涉及建筑基础工程技术领域，具体来说是一种具有内撑式夹紧结构的振动桩锤的夹桩器，所述夹紧结构包括一套筒和一安装在所述套筒内的夹紧油缸，若干楔形推动块与所述油缸底部连接，所述油缸带动所述楔形推动块沿套筒轴向上下运动，若干楔形夹紧块与所述楔形推动块的位置相配合，且配合面为斜面，所述楔形推动块沿轴向上下运动，使楔形夹紧块沿套筒径向运动，向外撑开后抵住待夹紧的桩管的内壁。本发明所提供的一种具有内撑式夹紧结构的振动桩锤的夹桩器，可以嵌入在管桩内部，由内向外撑开夹紧管桩，完美解决传统桩夹紧装置无法沉入地下的难题，并且夹紧力更大，有利于沉桩作业。
