Description
本発明は、採木その他の荷物をロープ状部材で吊り下げて移動させるために使用可能な吊上げ補助具に関する。 The present invention relates to a lifting aid that can be used to move a tree or other luggage by hanging it with a rope-like member.
従来、図５（Ａ）に示すように、ローラ１とフック２とを備え、ローラ１で案内されたワイヤーロープ３を荷物４に巻き掛け、ワイヤーロープ３の端部をフック２に係合させて荷物４を絞り吊りするためのチョーカーフックが知られている。
また、図５（Ｂ）に示すように、端部にＣ形金具（Ｃカン）５が取り付けられたワイヤーロープ３を荷物４に巻き掛け、Ｃ形金具５をワイヤーロープ３に掛けて荷物４を絞り吊りするものが知られている。
また、ワイヤーロープを蛇状に折れ曲がった貫通孔に通して装着し、締着治具でワイヤーロープを締着するものが開示されている（例えば、特許文献１参照）。
Conventionally, as shown in FIG. 5A, a roller 1 and a hook 2 are provided, a wire rope 3 guided by the roller 1 is wound around a load 4, and an end of the wire rope 3 is engaged with the hook 2. A choker hook for squeezing and hanging a load 4 is known.
As shown in FIG. 5 (B), a wire rope 3 having a C-shaped bracket (C-can) 5 attached to the end is wrapped around the luggage 4, and the C-shaped bracket 5 is hung on the wire rope 3 to load the luggage 4. The thing which squeezes and suspends is known.
In addition, there is disclosed a device in which a wire rope is inserted through a through-hole bent in a snake shape, and the wire rope is fastened with a fastening jig (for example, see Patent Document 1).
しかしながら、図５（Ａ）に示すチョーカーフック、図５（Ｂ）に示すＣ形金具および特許文献１に記載のワイヤーロープ弛み止め治具では、ワイヤーロープとローラ、Ｃ形金具または締着治具との接点でワイヤーロープに荷重がかかるため、ワイヤーロープがその接点で折れ曲がり、傷みやすいという課題があった。また、チョーカーフック、Ｃ形金具または締着治具の付近の上部に隙間ができやすいため、荷振れしたとき、ワイヤーロープで締め付けられていない荷物が抜け落ちるおそれがあるという課題があった。また、図６に示すように、玉掛け作業の際、玉掛ワイヤーロープ６は鋼材などの荷物７の中心側に寄りやすいため、中心に寄って荷物が不安定にならないようワイヤーロープ６を押さえておく必要があり、作業効率が悪いという課題があった。 However, in the choker hook shown in FIG. 5A, the C-shaped fitting shown in FIG. 5B, and the wire rope loosening prevention jig described in Patent Document 1, a wire rope and a roller, a C-shaped fitting or a fastening jig are used. Since a load is applied to the wire rope at the point of contact with the wire rope, the wire rope is bent at the point of contact and is liable to be damaged. In addition, there is a problem in that a gap is easily formed in the upper portion near the choker hook, the C-shaped bracket or the fastening jig, so that when the cargo deflects, the luggage not fastened by the wire rope may fall off. Also, as shown in FIG. 6, during the slinging operation, the slinging wire rope 6 tends to lean toward the center of the luggage 7 such as a steel material. There was a problem that the work efficiency was poor.

吊上げ補助具の作用について説明する。
吊上げ補助具１０は、予め、管材１１の貫通孔１１ａにロープ状本体２１を貫通させてある。図５（Ｃ）に示すように、荷物４を吊り上げる際、ストッパ２２と管材１１との間のロープ状本体２１を荷物４に巻き掛け、締め付ける。荷物４は、木材、鋼材、建材、その他いかなる物であってもよい。次に、ストッパ２２の後部２２ｇ側のロープ状本体２１を側面から挿入溝１２ｅに挿入させて大径孔１２ａおよび小径孔１２ｂに位置付ける。また、ロープ状本体２１を側面からガイド溝孔１３ｂに挿入させてガイド孔１３ａに位置付ける。次に、ストッパ２２の後部２２ｇを挿入口１２ｄに挿入させる。こうして、図１に示すように、ストッパ２２と係合部１２とを容易かつ確実に係合させることができる。このとき、ロープ状本体２１をガイド孔１３ａに位置付けることにより、係合部１２との接点でロープ状本体２１の１点に集中した荷重がかかるのを防止し、ロープ状本体２１を傷みにくくすることができる。
The operation of the lifting aid will be described.
In the lifting aid 10, the rope-shaped main body 21 is passed through the through-hole 11 a of the pipe 11 in advance. As shown in FIG. 5C, when lifting the load 4, the rope-shaped main body 21 between the stopper 22 and the tube 11 is wound around the load 4 and fastened. The luggage 4 may be wood, steel, building material, or any other thing. Next, the rope-shaped main body 21 on the rear portion 22g side of the stopper 22 is inserted into the insertion groove 12e from the side surface and positioned in the large-diameter hole 12a and the small-diameter hole 12b. Further, the rope-shaped main body 21 is inserted into the guide slot 13b from the side surface and positioned in the guide hole 13a. Next, the rear portion 22g of the stopper 22 is inserted into the insertion port 12d. Thus, as shown in FIG. 1, the stopper 22 and the engaging portion 12 can be easily and reliably engaged. At this time, by positioning the rope-shaped main body 21 in the guide hole 13a, it is possible to prevent a concentrated load from being applied to one point of the rope-shaped main body 21 at a contact point with the engaging portion 12 and to make the rope-shaped main body 21 hardly damaged. be able to.
図５（Ｃ）に示す状態で、ロープ状本体２１の輪２３をクレーンで吊って、荷物４を吊り上げる。貫通孔１１ａは円弧状に湾曲しているため、ロープ状本体２１の１点に集中した荷重がかかりにくく、ロープ状本体２１を傷めにくい。また、ロープ状本体２１は、緩やかな円形に湾曲するので、破損しにくい。 In the state shown in FIG. 5C, the load 23 is lifted by suspending the loop 23 of the rope-shaped main body 21 with a crane. Since the through hole 11a is curved in an arc shape, a concentrated load is hardly applied to one point of the rope-shaped main body 21, and the rope-shaped main body 21 is hardly damaged. Further, since the rope-shaped main body 21 is curved in a gentle circular shape, it is hardly damaged.
ストッパ２２が係合部１２と係合したとき、ロープ状本体２１は貫通孔１１ａの内部のロープ状本体２１と交差するため、荷物４を締め付けたロープ状部材２０の上部の隙間を小さくすることができ、荷物４をしっかりと締め付けることができる。このため、荷振れしたとき、荷物４が抜け落ちにくく、玉掛け作業の際にもロープ状部材２０が荷物４の中心側に寄りにくいので、安全かつ作業効率が良好である。また、ワイヤーロープの弛みが少ないため、ワイヤーロープをずれないよう押さえておく必要が少ない。作業者は玉掛け作業の合図をしやすいため、作業の危険度を大幅に軽減することができる。 When the stopper 22 is engaged with the engaging portion 12, the rope-shaped main body 21 intersects with the rope-shaped main body 21 inside the through-hole 11a. The luggage 4 can be securely tightened. For this reason, when the load swings, the load 4 is less likely to fall off, and the rope-shaped member 20 is less likely to lean toward the center of the load 4 during the slinging operation, so that safety and work efficiency are good. Also, since the wire rope is not loosened, there is little need to hold the wire rope so as not to shift. Since the worker can easily signal the slinging operation, the risk of the operation can be greatly reduced.
次に、図４に基づき、本発明の実施の形態の吊上げ補助具の変形例について説明する。
なお、図４において、図１および図２に示す部分と同一の部分には同一の符号を付し、重複した説明を省略する。
図４に示すように、管材１１は、管材溝孔３０を側部に有している。管材溝孔３０は、ロープ状本体２１を側面から貫通孔１１ａに挿入可能で、ストッパ２２の径より小さい幅を有している。管材溝孔３０は、管材１１の両端まで伸びている。吊上げ補助具１０ａは、複数の保持部材３１を有している。保持部材３１は、断面Ｃ字状のスナップリングから成り、管材溝孔３０を跨いで貫通孔１１ａの内部にロープ状本体２１を保持するよう管材１１に取り付けられる。
Next, a modification of the lifting aid according to the embodiment of the present invention will be described with reference to FIG.
In FIG. 4, the same portions as those shown in FIGS. 1 and 2 are denoted by the same reference numerals, and redundant description will be omitted.
As shown in FIG. 4, the tube material 11 has a tube material slot 30 on the side. The tube material slot 30 has a width smaller than the diameter of the stopper 22 so that the rope-shaped main body 21 can be inserted into the through hole 11a from the side surface. The tube material slot 30 extends to both ends of the tube material 11. The lifting aid 10a has a plurality of holding members 31. The holding member 31 is formed of a snap ring having a C-shaped cross section, and is attached to the tube 11 so as to hold the rope-shaped main body 21 inside the through hole 11 a across the tube material slot 30.
図４に示す吊上げ補助具１０ａを用いる場合、図２（Ｅ）に示すような市販のロープ状部材２０のロープ状本体２１を側面から管材溝孔３０に挿入させて貫通孔１１ａに位置付ける。管材溝孔３０を跨ぐよう保持部材３１を管材１１に取り付ければ、貫通孔１１ａの内部にロープ状本体２１を保持することができる。このため、予め、管材１１の貫通孔１１ａにロープ状本体２１を貫通させておく必要がなく、吊上げ補助具１０ａを既存のロープ状部材２０に容易に取り付けることができる。図４に示す吊上げ補助具１０ａは、図１および図２に示す吊上げ補助具１０と同様に使用することができる。 When the lifting aid 10a shown in FIG. 4 is used, the rope-shaped main body 21 of a commercially available rope-shaped member 20 as shown in FIG. 2E is inserted into the tube material slot 30 from the side surface and positioned in the through-hole 11a. If the holding member 31 is attached to the tube material 11 so as to straddle the tube material hole 30, the rope-shaped main body 21 can be held inside the through hole 11a. For this reason, there is no need to previously penetrate the rope-shaped main body 21 through the through-hole 11a of the tube material 11, and the lifting aid 10a can be easily attached to the existing rope-shaped member 20. The lifting aid 10a shown in FIG. 4 can be used similarly to the lifting aid 10 shown in FIGS.
なお、吊上げ補助具１０または吊上げ補助具１０ａには、クレーンのフックと係合可能なリングが設けられていてもよい。 The lifting aid 10 or the lifting aid 10a may be provided with a ring that can be engaged with a hook of a crane.
