特許第２７８４７２９号公報Japanese Patent No. 2784729

従来、鋼管管端クロップ等のスクラップ品が入ったバッグの搬出作業においては、鋼管搬送ライン内のバッグ受け渡し場所と、バッグ運搬車のバッグ載置台との間で、車載クレーンを用いてバッグ受け渡しを行うに際し、前記鋼管搬送ライン内に入って手作業で吊具チェーンフックを前記バッグの吊手ピン部に掛けるあるいは取り外しする玉掛作業を行っていた。この玉掛作業においては前記鋼管搬送ラインを停止する必要があり、また、専属の作業員が必要であったため、ロスタイム削減と省力化の両面から遠隔操作での玉掛作業の実現が課題となっていた。 Conventionally, in carrying out a bag containing scrap products such as steel pipe end crops, the bag is delivered using an in-vehicle crane between the bag delivery place in the steel pipe conveyance line and the bag mounting table of the bag conveyance vehicle. In doing so, a slinging operation was performed in which the hanger chain hook was hung on or removed from the hanger pin portion of the bag by entering the steel pipe conveyance line and manually. In this slinging work, it was necessary to stop the steel pipe conveyance line, and since a dedicated worker was required, realization of slinging work by remote control was an issue from both the viewpoint of reducing loss time and saving labor. .

前記特許文献１に記載の技術によれば、遠隔操作による玉掛作業が可能であるが、これを鋼管管端クロップ等のスクラップ品を入れるスクラップバッグに適用するのは困難である。というのは、鋼管管端クロップ等のスクラップ品を入れるバッグは、コンベアで搬送されてきた鋼管の管端不良部(クロップ)および切削の際に発生する切削屑（長い屑は数メートルあり）が上方から落下されてきたのを回収するものであるところ、前記特許文献１ではフックがラック上部に突起しているため、(1)切削屑がフックに絡みつき、吊具側のピンによる係止が不能となる虞があり、また、(2) 落下されるクロップは長尺重量物（最大長さ９００ｍｍ、最大重量２７０ｋｇ/本）であり、バッグに入ったクロップの姿勢が崩れた際、クロップがフックに当る、またはクロップ落下時にクロップが跳ねてフックに当る等でフックが曲がってしまう虞もある。 According to the technique described in Patent Document 1, a sling operation by remote operation is possible, but it is difficult to apply this to a scrap bag in which scrap products such as steel pipe end crops are placed. The reason for this is that the bag that contains scraps such as steel pipe end crops, the pipe end defective part (crop) of the steel pipe that has been transported by the conveyor and the cutting waste (long waste is several meters) generated during cutting In the above-mentioned patent document 1, since the hook protrudes from the upper part of the rack, (1) the cutting waste gets entangled with the hook and is locked by the pin on the lifting tool side. (2) The crop that is dropped is a long heavy object (maximum length 900mm, maximum weight 270kg / piece). When the posture of the crop in the bag collapses, There is a possibility that the hook may be bent when it hits the hook, or when the crop falls, the crop jumps and hits the hook.

本発明は、前記課題を解決するためになされたものであり、その要旨構成は次のとおりである。
（１）クレーンに吊った吊具でバッグを吊持するに用いる遠隔玉掛機構であって、前記吊具は、前記バッグをコの字形に囲むコの字形枠の両腕部に複数のフック形具足をそれらのフック形の開口を同一配向として配設するとともに、前記クレーンから吊り下げた吊具チェーンフックを前記両腕部に２ケ所ずつ固定し、かつ前記腕部の先端部分を下曲がり形状としたものとし、前記バッグには、前記複数のフック形具足を各々係止する複数の吊手ピンと、前記腕部の下曲がり形状の先端部分を受けて前記吊具を前記吊手ピンによる前記フック形具足の係止位置へ案内可能な逆ハの字形受座とを配設したことを特徴とする遠隔玉掛機構。 The present invention has been made to solve the above problems, and the gist of the present invention is as follows.
(1) A remote sling mechanism used to suspend a bag with a hanging tool suspended from a crane, wherein the hanging tool has a plurality of hook shapes on both arms of a U-shaped frame surrounding the bag. The hooks are arranged with their hook-shaped openings in the same orientation, the chain hooks suspended from the crane are fixed to the two arms at two locations , and the tip of the arms are bent downward. The bag includes a plurality of suspension pins that respectively lock the plurality of hook-shaped tool legs, and a lower bent tip portion of the arm portion.

本発明の実施形態の一例を示す概略図Schematic showing an example of an embodiment of the present invention 図１の例を用いた遠隔玉掛作業の手順を示す概略側面図Schematic side view showing the procedure of remote sling work using the example of FIG.

図１は、本発明の実施形態の一例を示す概略図（(a)(b)は斜視図、(c)は(b)のA矢視図）である。図示のように、本発明の遠隔玉掛機構において、吊具1はそれぞれの腕部３に２本ずつの吊具チェーンフック10を介してクレーン（図示省略）で吊られてバッグ2を吊持するに用いられる。この吊具1は、バッグ2をコの字形に囲むコの字形枠1Aの両腕部3に複数のフック形具足4をそれらのフック形の開口を同一配向として配設したものとした。なお、この例では、複数のフック形の開口は、いずれも腕部3の先端側に向く配向とした。また、腕部3の先端部分5は下曲がり形状とした。一方、バッグ2には、前記複数のフック形具足4を各々係止する複数の吊手ピン6と、前記腕部3の下曲がり形状の先端部分5を受けて吊具1を前記吊手ピン6による前記フック形具足4の係止位置へ案内可能な逆ハの字形受座7を配設した。なお、この例では、受座7は、バッグ2の側壁上部を内側に傾斜させてなるバッグ外側開先テーパ面7Aと、バッグ2の側壁に接合した耳部材9の内側に設けた耳部内側開先テーパ面7Bとで構成した。
FIG. 1 is a schematic view showing an example of an embodiment of the present invention ((a) and (b) are perspective views, and (c) is a view taken in the direction of arrow A in (b)). As shown in the figure, in the remote sling mechanism of the present invention, the hanging tool 1 is hung by a crane (not shown) via two hanging tool chain hooks 10 on each arm 3 to hold the bag 2. Used for. In this hanging tool 1, a plurality of hook-shaped legs 4 are arranged on both arms 3 of a U-shaped frame 1A surrounding a bag 2 in a U-shape so that the hook-shaped openings thereof are in the same orientation. In this example, the plurality of hook-shaped openings are all oriented toward the distal end side of the arm 3. In addition, the tip portion 5 of the arm 3 is bent downward. On the other hand, the bag 2 receives a plurality of suspender pins 6 that respectively lock the plurality of hook shape legs 4 and a lower bent tip portion 5 of the arm portion 3 to suspend the suspender 1 from the suspender pins. An inverted U-shaped seat 7 that can be guided to the locking position of the hook-shaped tool foot 4 according to 6 is provided. In this example, the seat 7 has a bag outer groove tapered surface 7A formed by inclining the upper part of the side wall of the bag 2 inward, and an inner side of the ear part provided on the inner side of the ear member 9 joined to the side wall of the bag 2. A groove taper surface 7B is used.

バッグ運搬車に搭載したクレーンで吊具1を吊下ろす際（天井クレーンでも同様）、吊下ろす位置は多少ばらつく（例えば±２００ｍｍ程度ばらつく）ものであるが、逆ハの字形受座7を配設したことにより、吊下ろし位置に多少のばらつきがあっても、図１(b)に示されるように、腕部3の下曲がり形状の先端部分5が受座7とスムーズに係合するので、クレーン操作だけで、吊具1を吊手ピン6によるフック形具足4の係止位置へ案内することが可能である。 When hanging the lifting tool 1 with a crane mounted on a bag carrier (the same applies to an overhead crane), the hanging position varies slightly (for example, about ± 200 mm), but a reverse-shaped receiving seat 7 is provided. As a result, even if there is some variation in the hanging position, as shown in FIG. 1 (b), the lower bent end portion 5 of the arm portion 3 smoothly engages with the seat 7. It is possible to guide the hanging tool 1 to the locking position of the hook-shaped tool foot 4 by the hanging pin 6 only by operating the crane.

図１の例を用いた遠隔玉掛作業の手順を概略側面図にて図２に示す。この遠隔玉掛作業は終始、バッグから遠隔した場所からのクレーン操作のみで行われる。
バッグ2を吊上げる場合、図２(a)(b)(c)(d)の順で作業を進める。すなわち、吊具1をその腕部3の下曲がり形状の先端部分5がバッグ2の逆ハの字形受座7のほぼ直上にくるように吊持し、下降11させる(a)と、吊具1の下曲がり形状の先端部分5が逆ハの字形受座7内に収まるとともにフック形具足4の開口位置よりも腕部先端側に寄った位置で腕部3底が吊手ピン6で支持される(b)。そこで、吊具1を前進12させると、吊手ピン6がフック形具足4の開口から懐内に入り、懐内奥面に当って前進12が止まる(c)。そこで、吊具1を上昇13させると、フック形具足4が吊手ピン6で係止されてバッグ2が吊上げられる(d)。 FIG. 2 is a schematic side view showing the procedure of remote slinging using the example of FIG. This remote slinging operation is performed only by operating the crane from a location remote from the bag.
When the bag 2 is lifted, work is performed in the order of FIGS. 2 (a), (b), (c), and (d). That is, the suspension tool 1 is suspended so that the lower bent tip portion 5 of the arm portion 3 is almost directly above the reverse-shaped receiving seat 7 of the bag 2 and is lowered 11 (a). 1 The lower bent tip 5 fits in the inverted C-shaped seat 7 and the arm 3 bottom is supported by the suspension pin 6 at a position closer to the tip of the arm than the opening of the hook shaped foot 4 (B). Therefore, when the hanging tool 1 is moved forward 12, the hanging pin 6 enters the pocket through the opening of the hook-shaped tool foot 4, hits the inner surface of the pocket, and the forward movement 12 stops (c). Therefore, when the lifting tool 1 is raised 13, the hook-shaped tool foot 4 is locked by the lifting pin 6 and the bag 2 is lifted (d).

バッグ2を吊下ろす場合は上記とは逆に、図２(d)(c)(b)(a)の順で作業を進める。すなわち吊下ろし直後(d)からさらに吊具1を下降14させると、腕部3底が吊手ピン6に当って下降14が止まる(c)。そこで吊具1を後退15させると、吊手ピン6がフック形具足4の開口から懐外に出る(b)。そこで吊具1を上昇16させると、吊具1はバッグ2から上方に離間する。
なお、上述の実施形態では吊具1を前進あるいは後退させることで、フック形具足4の懐内への吊手ピン6の出し入れを行っているが、クレーン操作により吊具1の前進あるいは後退を行えない場合には、バッグ2を前後移動可能なバッグ載置台に載せておき、このバッグ載置台を前後移動させることで、フック形具足4の懐内への吊手ピン6の出し入れを行うようにしてもよい。 When the bag 2 is suspended, the work is advanced in the order shown in FIGS. 2D, 2C, 2B, and 2A, contrary to the above. That is, when the hanger 1 is further lowered 14 immediately after being hung (d), the bottom of the arm 3 hits the hanger pin 6 and the descent 14 stops (c). Then, when the hanging tool 1 is retracted 15, the hanging pin 6 comes out of the opening of the hook-shaped tool foot 4 (b). Therefore, when the hanging tool 1 is raised 16, the hanging tool 1 is separated upward from the bag 2.
In the above-described embodiment, the hoisting pin 1 is moved forward or backward to move the hook pin 6 into and out of the pocket of the hook-shaped tool foot 4, but the hoisting tool 1 is moved forward or backward by crane operation. If this is not possible, place the bag 2 on the bag mounting table that can be moved back and forth, and move the bag mounting table back and forth so that the hook pin 6 can be inserted into and removed from the pocket of the hook shape foot 4 It may be.
