PILE DRIVER
To provide a pile driver comprising a leader positioning member that enables one basic leader to be reused when rearranging a rotation leader and a non-rotation leader.SOLUTION: A pile driver includes a leader positioning member that determines a connection angle in a leader circumferential direction when connecting a lower leader and a basic leader. The leader positioning member consists of a lock pin that engages with a leader rotation mechanism in a leader rotation specification, and a joint pin 47 that connects vertically neighboring guide pipes 31, 31 in a leader non-rotation specification. The joint pin comprises: a base 48 that is fixed to an opening of one guide pipe of the vertically neighboring guide pipes; a pin main body 49 that can be inserted into and removed from an opening of the other guide pipe; and a bolt 51 for attaching the pin main body that passes through the pin main body and screws into a screw hole 48a provided in the base. The pin main body is configured to be detachable in accordance with changes in specifications between the leader rotation specification and the leader non-rotation specification.SELECTED DRAWING: Figure 7
【課題】回動型のリーダと非回動型のリーダとを組み替える際に、１つの基本リーダを使い回すことが可能なリーダ位置決め部材を備えた杭打機を提供する。【解決手段】杭打機は、下部リーダと基本リーダとを連結する際のリーダ周方向の連結角度を確定させるリーダ位置決め部材を有し、リーダ位置決め部材は、リーダ回動仕様でリーダ回動機構に係止されるロックピンと、リーダ非回動仕様で上下隣り合うガイドパイプ３１，３１同士を接続するジョイントピン４７とからなり、ジョイントピンは、上下隣り合うガイドパイプ同士の一方のガイドパイプの開口部に固着した基部４８と、他方のガイドパイプの開口部に挿抜可能なピン本体部４９と、該ピン本体部を貫通して基部に設けられたねじ孔４８ａに螺合するピン本体部取付用のボルト５１とを備え、リーダ回動仕様とリーダ非回動仕様との仕様変更に応じてピン本体部が着脱可能に構成されている。【選択図】図７
