It is a ■-■-■ side view of the figure. As shown in the drawings, in the device B of the present invention, a sheave mounting base 5 is fixed to a derrick post 4.
シーブ取付台５には、ドラム６人を有するウィンチ６の
ドラム接線方向に軸線がほぼ向く軸承部７．７が前後に
間隔をおいて設けられている。The sheave mounting base 5 is provided with shaft bearings 7.7 at intervals in the front and rear, the axis of which is substantially oriented in the tangential direction of the drum of the winch 6 having six drum members.
軸承部７，７には、シーブ支持部材８の下部を形成して
いる管軸９の前後両端部が挿入され支持されている。Both front and rear ends of a tube shaft 9 forming the lower part of the sheave support member 8 are inserted into and supported by the shaft bearings 7, 7.
管軸９の左右両側には、互いに平行する軸承壁１０．１
０が固着されておシ、中間部には上向きの索条通口１１
が開口している。Shaft bearing walls 10.1 parallel to each other are provided on both left and right sides of the tube shaft 9.
0 is fixed, and there is an upward cable passage 11 in the middle part.
is open.
軸承壁１０．１０の下部には、管軸９よシも下方に突出
する板状のバランスウェイト１２が固着されている。A plate-shaped balance weight 12 is fixed to the lower part of the shaft bearing wall 10.10 and protrudes downward from the tube shaft 9 as well.
一方、軸承壁１０．１０には、索条通口１１の直上方に
おいて軸ボルト１３が挿通されており、軸ポルト１３に
はシーブ３が空転自在に支持されている。On the other hand, a shaft bolt 13 is inserted through the shaft bearing wall 10.10 directly above the cable passageway 11, and the sheave 3 is supported by the shaft port 13 so as to be freely rotatable.
なお、図中符号１４は軸ポルト１３に螺合するナツト、
１５は軸承壁１０．１０の間隔保持用スリーブをそれぞ
れ示す。Note that the reference numeral 14 in the figure is a nut screwed into the shaft port 13;
15 designates the spacing sleeves of the bearing walls 10.10, respectively.
この発明の装置Ｂは、上記のように構成されているので
、デリックポスト４に固着したシーブ取付台５に対し、
シーブ支持部材８が管軸９を中心に左右に首振り自在に
傾動する。Since the device B of the present invention is configured as described above, the sheave mounting base 5 fixed to the derrick post 4 can be
The sheave support member 8 tilts freely left and right about the tube shaft 9.
一方、一端がブーム（図示しない）に固着され、他端が
ウィンチ６のドラム６Ａに固定されている索条１の中間
部分はシーブ３に掛は渡され、ウィンチ側となる部分は
管軸９の索条通口１１を通って管軸９に挿通されている
。On the other hand, the middle part of the cable 1, which has one end fixed to a boom (not shown) and the other end fixed to the drum 6A of the winch 6, is passed over the sheave 3, and the part on the winch side is attached to the tube shaft 9. The tube shaft 9 is inserted through the cable passageway 11 of the cable.
なお、バランスウェイト１２．１２は、索条１が無負荷
状態にあるとき、シーブ３を支持しているシーブ支持部
材８に直立状態での復帰習性を与える。Note that the balance weight 12.12 gives the sheave support member 8 supporting the sheave 3 the habit of returning to the upright state when the cable 1 is in an unloaded state.
このように索条１を案内するこの発明の装置Ｂは、ブー
