本発明は、重量物を牽引する場合などに用いられるワイ
ヤロープのグリップ装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wire rope gripping device used for towing heavy objects.
ワイヤロープによる重量物の牽引手段としては第１図に
示すようなものがあり、重量物Ｗを牽引′するワイヤロ
ープ１は、前後一対のプラー２．２からなるグリツー
プ式駆動機構へを経由して、リール３により巻取られる
ようになっている。There is a means for pulling heavy objects using a wire rope as shown in FIG.
It is wound up by a reel 3 via a pull-type drive mechanism.
各プラー２は、ワイヤｏ−ｙ”１を挿通されたがイド部

れたグリップ用油圧シリンダ７とをそなえでいる。Each puller 2 includes a guide member 4 through which the wire o-y"1 is inserted, and a main hydraulic cylinder 5 capable of driving the guide member 4 in the longitudinal direction of the wire rope 1.
A pair of wedges 6.6 are fitted and removed between the inner periphery of the guide member 4 and the outer periphery of the wire rope 1 to clamp and release the wire rope 1, and each wedge 6 is arranged to be fitted and removed. It is equipped with a grip hydraulic cylinder 7.
そして、グリップ用油圧シリンダ７がクサビ６を押圧し

ガイド部材４を駆動することにより、ワイヤロープ１を
駆動することがで終るのであって、このような動作を前
後のプラー２，２で交互に行ならことにより、重量物Ｗ
の連続的な牽引が行なわれるようになっている。Then, the gripping hydraulic cylinder 7 presses the wedge 6 to make it into a fitting state, so that the guide member 4 is integrated with the wire rope 1, and then the main hydraulic cylinder 5 is actuated to drive the guide member 4. This ends with driving the wire rope 1, and if such an operation is performed alternately with the front and rear pullers 2, it is possible to move the heavy object W.
Continuous traction is now taking place.
ところで、ガイド部材４およびクサビ６によるワイヤロ
ープ１のグリップ手段では、ガイド部材４とクサビ６と
の接触面の摩擦をできるだけ小さくすることが重要であ
る。By the way, in the gripping means of the wire rope 1 using the guide member 4 and the wedge 6, it is important to minimize the friction of the contact surface between the guide member 4 and the wedge 6.
そこで、従来は、この接触面をグリースにより潤滑する
ことが行なわれているが、このような手段では次のよう
な不具合がある。Conventionally, this contact surface has been lubricated with grease, but this method has the following disadvantages.
すなわち、長時間にわたり使用している間にグリースが
押し出されて減少すると、ガイド部材４とクサビ６との
摩擦が過大になって、ワイヤロープ１を十分に把持でき
なくなり、クサビ６の抜き出しも困難になる。That is, when the grease is pushed out and reduced during long-term use, the friction between the guide member 4 and the wedge 6 becomes excessive, making it impossible to grip the wire rope 1 sufficiently and making it difficult to pull out the wedge 6. become.
また、上述の摩擦持触が更に苛酷になると、焼付きを生
じたり、摩耗粉を生ヒたりしで、ワイヤロープに対する
把持機能を発揮できなくなる。Furthermore, if the above-mentioned frictional contact becomes even more severe, seizure may occur or abrasion particles may be exposed, making it impossible to exert the gripping function on the wire rope.
本発明は、これらの問題点の、解消をはかろうとするも
ので、上述のがイド部材とクサビとの摩擦を緩和してワ

る。For this reason, the wire rope gripping device of the present invention has a guide member into which a wire rope is inserted, and is fitted into and removed from the inner periphery of this guide member and the outer periphery of the wire rope to clamp and release the wire rope. It is equipped with a pair of wedges that can be rotated, and a gripping hydraulic cylinder that is arranged to fit and remove these wedges, and a lubricating plate made of a polymeric material is provided on both sides between the inner periphery of the guide member and the wedge. It is characterized by a spring that is slidably inserted and biases the lubricating plate in the direction of the wedge.
以下、図面により本発明のワイヤロープのグリップ装置
について説明すると、第２図はその縦断面図、第３図は
第２図のＩＩＩ−ＩＩＩ矢視断面図であって、ワイヤロ

油圧シリンダで、ワイヤロープ１１の長手方向に駆動さ
れるように設けられている。Hereinafter, the wire rope gripping device of the present invention will be explained with reference to the drawings. FIG. 2 is a longitudinal sectional view thereof, and FIG. 3 is a sectional view taken along the line III--III in FIG. The wire rope member 12 is provided so as to be driven in the longitudinal direction of the wire rope 11 by a main hydraulic cylinder (not shown).
そして、がイド部材１２の内周とワイヤロープ１１の外
周との間に一対のクサビ１３が嵌脱可能に設けられてお
り、これらのクサビ１３の嵌脱によりワイヤロープ１１
の挟持および解放が行なわれるようになっている。A pair of wedges 13 are removably provided between the inner periphery of the guide member 12 and the outer periphery of the wire rope 11, and when these wedges 13 are fitted and removed, the wire rope 11
The clamping and releasing of the parts are carried out.
なお、各クサビ１３の嵌脱は、グリップ用油圧シリンダ
１４により行なわれる。Note that each wedge 13 is fitted and removed by a grip hydraulic cylinder 14.
本発明のグリップ装置では、特に〃イド部材１２の内周

５が両面滑動可能に介挿され、各潤滑板１５は両面にグ
リースを塗布されている。In the grip device of the present invention, in particular, a lubricating plate 1 made of a polymeric material is provided between the inner circumference of the id member 12 and each wedge 13.
5 is inserted so as to be slidable on both sides, and each lubricating plate 15 is coated with grease on both sides.
また各潤滑板１５をクサビ１３の親方向に付勢するバネ
１６が取付けられている。Further, a spring 16 is attached that biases each lubricating plate 15 in the direction of the wedge 13.

介して滑動するので、過大な摩擦による焼付鯵や摩耗の
発生を防止することができ、ワイヤロープ１１に対する
把持およびその解放驚円滑に行なうことができる。With the above configuration, even if the grease decreases during use,
Since the guide member 12 and the wedge 13 slide through the low-friction lubricating plate 15, it is possible to prevent seizure or wear due to excessive friction, and the wire rope 11 can be gripped and released smoothly. can be done.

触係合したのちは、各クサビ１３と潤滑板１５との摩擦
力により、潤滑板１５はクサビ１３に追従して前進し、
これに伴９てバネ１６が伸長する。In addition, since each wedge 13 is attached with a spring 16 that biases it in the parent direction, when pushing the wedge 13 in the fitting direction with the grip hydraulic cylinder 14, the wedge 1
3 moves forward and the lubricating plate 15 remains, and after each wedge 13 contacts and engages both the wire rope 11 and the lubricating plate 15, due to the frictional force between each wedge 13 and the lubricating plate 15, The lubricating plate 15 moves forward following the wedge 13,
Along with this, the spring 16 expands.
したがって、クサビ１３を親方向へ抜き出す際には、バ
ネ１６の力を利用することができ、これによりグリップ
用油圧シリンダ１４の能力が小さくてすむ利点がある。Therefore, when pulling out the wedge 13 in the parent direction, the force of the spring 16 can be used, which has the advantage that the capacity of the gripping hydraulic cylinder 14 can be small.
またクサビ１３を嵌方向に押込んだ状態から、次にこれ

接触面に僅かな隙間を生じる。Further, when the wedge 13 is pushed in in the fitting direction and then removed, the gripping hydraulic cylinder 14 first pulls out the wedge 13 a little (about several millimeters), creating a small gap on the contact surface.

円滑に行なわれるのである。Then, the lubricating plate 15 is quickly pulled out by the force of the spring 16, and a large gap is created between the id member 12 and each wedge 13, so that the wedge 13 can be pulled out properly and smoothly.

うる利点がある。As described in detail above, according to the wire rope gripping device of the present invention, a pair of wedges for gripping the wire rope are provided between the outer circumference of the wire rope and the inner circumference of the guide member through which the wire rope is inserted. A lubricating plate made of polymer material is inserted so as to be able to slide on both sides by opening between each wedge and the inner periphery of the guide member, and a spring biases the lubricating plate in the direction of detaching the wedge. This simple structure reduces the space required for the gripping hydraulic cylinder that drives the wedge, while also making it possible to grip and release the wire rope efficiently and smoothly, which was a problem in the past. This has the advantage of sufficiently preventing problems such as seizure due to excessive frictional force.
