この考案はコンテナ等荷役の運搬作業を行なうクレーン
の吊ビーム振れ止め装置に関し、特にロープシープ保持
部の構成を改良した吊ビーム振れ止め装置に関する。[Detailed Description of the Invention] This invention relates to a hanging beam steadying device for a crane that carries out cargo handling operations such as containers, and particularly relates to a hanging beam steadying device with an improved structure of a rope sheep holding section.
さきに出願人において、この種吊ビーム振れ止め装置を
提供したが、その装置は、第1図に示すごとくトロリ1
の側面に左右一対の振子レバ2゜2の上端部を枢支し、
それらの下端部に軸支したロープシープ3,3に巻上げ
ロープ4,4を介してスプレッダ5の巻上シーブ6.6
を吊持させて前記振子レバ2,2を液圧シリンダ7.7
で相対方向へ拡縮作動させる構成としている。The applicant previously provided this type of suspension beam steady resting device, and the device was designed to support a trolley 1 as shown in Fig. 1.
The upper ends of a pair of left and right pendulum levers 2゜2 are pivotally supported on the sides of the
The hoisting sheaves 6.6 of the spreader 5 are passed through the hoisting ropes 4, 4 to the rope sheaves 3, 3 pivotally supported at their lower ends.
The pendulum levers 2, 2 are suspended from the hydraulic cylinder 7.7.
It is configured to expand and contract in the relative direction.
そして、前記スプレッダ5に吊荷8を吊持させた状態で
トロリ1を横行させることにより荷役搬送を行なうので
あるが、その場合に、ロープシープ3,3相互が近寄っ

するために前記液圧シリンダ7.7を伸び作動させるこ
とにより振子レバ2,2を拡げてロープシープ3,3相
互を大きく離している。Load handling and transportation is carried out by moving the trolley 1 sideways with the suspended load 8 suspended by the spreader 5. In this case, when the rope sheep 3, 3 are close to each other and at a small distance from each other, Since load swing occurs, in order to prevent this, the pendulum levers 2, 2 are widened by extending the hydraulic cylinder 7.7, and the rope sheeps 3, 3 are separated from each other by a large distance.
ところが、前記ロープシープ3,3には、吊荷荷重によ

シープ相互を荷振れ防止のために小さいパワで随時円滑
に拡げることができるようにした吊ビニム振れ止め装置
を比較的簡単な構成で提供することにある。This idea was devised to solve the above problems, and its purpose was to bias a pair of rope sheeps provided on the trolley that can be expanded and contracted in relative directions, so that the suspended load could be A hanging vinyl steady rest device that balances the pulling force acting on each of the rope sheep due to the load, and thereby allows the rope sheep to spread smoothly at any time with a small power to prevent the load from swinging. The purpose is to provide a simple configuration.
以下に、この考案の一実症例を第2図および第3図に基
づいて説明する。An example of this invention will be explained below with reference to FIGS. 2 and 3.
第2図において、クレーン軌道用の桁10にはトロリ本
体11が上部のトロリ車輪12,13を介して横行自在
に吊持させである。In FIG. 2, a trolley body 11 is suspended from a crane track girder 10 via upper trolley wheels 12 and 13 so as to be able to move freely.
トロリ本体11は、その両側面に設けたシーブ保持用の
リンク機構14.15を有している。The trolley body 11 has link mechanisms 14 and 15 for holding sheaves provided on both sides thereof.
リンク機構14,15は、トロリ本体11の両側面にお
ける横方向離間位置にそれぞれの上端部を枢支した各一
対の振子レバ16,17と、これらの下端部に両端部を
軸18.19で回動自在に連結し、その連結部を下側回
動軸支部20,21として中間部を上側回動軸支部22
とした重錘しバ23,24とから構成されている。The link mechanisms 14 and 15 each include a pair of pendulum levers 16 and 17 whose upper ends are pivotally supported at laterally spaced positions on both sides of the trolley body 11, and shafts 18 and 19 with both ends attached to their lower ends. They are rotatably connected, with the connecting portion being the lower rotational shaft support 20 and 21 and the middle portion being the upper rotational shaft support 22.
It is composed of weight bars 23 and 24.
斯様なリンク機構14,15において、下側回動軸支部
20,21のそれぞれにはロープシープ25.26が、
かつ上側回動軸支部22には前記ロープシープ25,2
6相互を拡げる方向に付勢する手段としての重錘27が
それぞれ取付けである。In such a link mechanism 14, 15, a rope sheep 25, 26 is attached to each of the lower rotation shaft supports 20, 21.
In addition, the rope sheep 25, 2 is attached to the upper rotation shaft support 22.
6. A weight 27 is attached as a means for urging each other in the direction of expanding each other.
そして、前記リンク機構14,15は、それら両側の振
子レバ16,17の中間部とトロリ本体11側壁との間
に跨架したシリンダ28.29の伸縮作動でロープシー
プ25.26間を拡縮する方向へ駆動されるようになっ
ている。The link mechanisms 14 and 15 expand and contract between the rope sheeps 25 and 26 by the expansion and contraction of cylinders 28 and 29 that span between the intermediate portions of the pendulum levers 16 and 17 on both sides and the side wall of the trolley body 11. It is designed to be driven in the direction.
各ロープシープ25.26には、巻上装置(図示せず)
により巻上げ巻戻しされる巻上ロープ30を介してスプ
レッダ(吊ビーム)31上の巻上シーブ32.33がそ
れぞれ吊持させである。Each rope sheep 25.26 has a hoisting device (not shown)
The hoisting sheaves 32 and 33 are each suspended on a spreader (hanging beam) 31 via a hoisting rope 30 which is hoisted and rewound by a hoisting rope 30.
つぎに、上記実施例の作用を説明する。Next, the operation of the above embodiment will be explained.
まず、シリンダ28.29が縮まってロープシープ25
゜26相互が最も近くに引き寄せられた第2図中実線位
置にある状態で、巻上装置により巻上ロープ30を巻戻
すことによってスプレッダ31を所定位置まで下降させ
る。First, the cylinders 28 and 29 are contracted and the rope sheep 25
26 With the hoisting rope 30 reeled back by the hoisting device in the state shown by the solid line in FIG. 2 where they are drawn closest to each other, the spreader 31 is lowered to a predetermined position.
そのスプレッダ31に吊荷Wを吊持させたのち、巻上ロ
ープ30を巻上げることにより吊荷Wを所定高所に吊上
げた状態では、その荷重によって前記ロープシープ25
,26には強力な引き寄せ力Fが作用する。After the spreader 31 suspends the load W, when the load W is hoisted to a predetermined height by hoisting the hoisting rope 30, the load causes the rope sheep 25 to
, 26 are subjected to a strong attractive force F.
しかし、ロープシープ25.26には、重錘27により
相互を拡開する方向への付勢力Pが作用しているため、
その付勢力Pによって前記引き寄せ力Fはバランス化し
た状態となる。However, since the rope sheep 25 and 26 are biased by the weight 27 in the direction of expanding them,
The urging force P brings the attracting force F into a balanced state.
従って、ロープシープ25.26を荷振れ防止のために
横拡げする際のパワは小さくてすみ、その小さなパワの
シリンダ28,29を伸び作動させることにより、前記
ロープシープ25,26はリンク機構14,15を介し
て円滑に横拡がりする。Therefore, when the rope sheeps 25, 26 are spread horizontally to prevent load swinging, only a small amount of power is required. , 15, and spread smoothly laterally.
なお、以上の実施例において、ロープシープ25.26

きて頗ぶる経済的であるなど、クレーン性能の向上に寄
与するところの大きな実用的効果を発揮する。As explained above, this invention applies a force to a pair of rope sheeps, which receives a force in the direction of mutual attraction due to a suspended load attached to a trolley via a link mechanism, in the direction of lateral expansion. Since the pulling forces are balanced, the power needed to spread both rope sheep laterally to prevent load swinging is reduced, which makes it possible to reduce the output capacity of the link mechanism drive means. It has great practical effects, such as being more economical and contributing to improving crane performance.
