本考案はリーダが回転する杭打機において、リ
ーダを起伏する際に用いる一定の長さのガイドロ
ープ（以下ペンダントロープと称する）のリーダ
との連結構造に関するものである。[Detailed description of the invention] The present invention relates to a structure for connecting a guide rope of a certain length (hereinafter referred to as a pendant rope) to a leader in a pile driving machine in which the leader rotates, which is used when raising and lowering the leader. .
従来のリーダが回転する杭打機のリーダは下部

て、リーダが回転すると同時にペンダントロープ
２も左右へ回転移動するので、別のワイヤロープ
即ち２本の該ペンダントロープ２の間を通りかつ
左右へは殆んど動かない他用途のワイヤロープ３
にペンダントロープ２が干渉する欠点があつた。 The leader of a conventional pile driver in which the leader rotates is supported at the lower part at the front of the pile driver and at the upper part at the rear of the pile driver via two struts, and the connection between the pendant rope and the leader is the first one. As shown in FIGS. 1 to 3, a bracket 1a is provided on a leader 1, and a pendant rope 2
were directly connected. For this reason, during piling work, as the leader rotates, the pendant rope 2 also rotates left and right, so it passes between another wire rope, that is, the two pendant ropes 2, and hardly moves left or right. Wire rope for use 3
There was a drawback that the pendant rope 2 interfered with the cable.
これを防ぐ目的でペンダントロープ拡張装置４
を使用していたが、該ペンダントロープ拡張装置
４を所定位置へ取り付けたり取り外したりするに
は、リーダへ登つて片手・片足での作業となつて
困難かつ危険を伴つていた。 To prevent this, the pendant rope extension device 4
However, in order to attach or remove the pendant rope extension device 4 to a predetermined position, the operator must climb onto the leader and work with one hand and one foot, which is difficult and dangerous.
尚５はリーダ１を支持する為に左右に２本設け
られた伸縮可能な支柱である。 Reference numeral 5 designates two extendable and retractable columns provided on the left and right sides to support the leader 1.
本考案は上記欠点を解消する為になされたもの
であつて、リーダは回転してもそれ自体は回転し
ないリーダの支持環にペンダントロープを連結す
ることにより、ペンダントロープ拡張装置を使用
することなしに前記干渉をなくすることを目的と
する。 The present invention was made to solve the above-mentioned drawbacks, and by connecting the pendant rope to the support ring of the leader, which does not rotate even though the leader rotates, there is no need to use a pendant rope expansion device. The purpose is to eliminate the interference.
以下本考案を図面の一実施例に基づいて説明す
る。 The present invention will be explained below based on one embodiment of the drawings.
第４図は本考案構造の拡大側面図、第５図は第
４図の−断面図を表わす。 FIG. 4 is an enlarged side view of the structure of the present invention, and FIG. 5 is a cross-sectional view taken from FIG.
尚付号中第１図乃至第３図と同じものは、同等
の部分を指す。 In addition, the same parts as in FIGS. 1 to 3 in the attached numbers refer to equivalent parts.
６は支持環で、支柱５の上部にリーダ１に対し
て回動は自由であるが上下に移動しないようリー
ダ１へ嵌合し、支柱５，５の附設間隔ｌが従来非
常に狭かつたがこれを広く改善し該支柱取付間に
ペンダントロープ２，２を該支持環６のブラケツ
ト６ａに連結したものである。 Reference numeral 6 denotes a support ring, which is fitted onto the upper part of the support column 5 so that it can rotate freely relative to the leader 1, but does not move up or down. However, this has been greatly improved by connecting the pendant ropes 2, 2 to the bracket 6a of the support ring 6 between the support columns.
以上の如く構成してあるのでリーダ１を回転さ
せた場合、支持環６は２本の支柱５にて支えられ
回転せずに固定しているから、これに連結された
ペンダントロープ２は回転移動することがなく、
従つて所要の間隔を有した２本のペンダントロー
プ２の間を通つている他用途のワイヤロープ３と
は終始干渉しなくなると共に、従来から使用して
いたペンダントロープ拡張装置は不要となり、危
険をおかして取り付けなくて済む。 With the structure described above, when the leader 1 is rotated, the support ring 6 is supported by the two pillars 5 and is fixed without rotating, so the pendant rope 2 connected thereto rotates. There's nothing to do,
Therefore, there is no longer any interference with the wire rope 3 for other purposes passing between the two pendant ropes 2 with the required spacing, and the pendant rope extension device used in the past is no longer required, reducing the risk of danger. No need to mess up and install.
又、従来リーダを俯仰する途中に支持環６が左
右へ回動するのを防止する必要上第４図鎖線で示
すストツパ装置７を設けなければならずペンダン
トロープ拡張装置同様これの取付け取外しに面倒
であつたが、本考案によれば支持環６を直接ペン
ダントロープ２で引張るから回動することがな
く、前記ストツパ装置７を廃止することができる
等部品点数の減少によるコスト低減に寄与すると
ころが大きい等実用上極めて優れた考案である。 In addition, in order to prevent the support ring 6 from rotating to the left and right while the conventional leader is being lifted up or down, a stopper device 7, shown in broken lines in FIG. However, according to the present invention, since the support ring 6 is directly pulled by the pendant rope 2, it does not rotate, and the stopper device 7 can be eliminated, which contributes to cost reduction by reducing the number of parts. It is a very good idea in practical terms, such as its large size.
