Description

本発明は、クレーンで、建築資材等の運搬に使用される伸縮ビームを備えた伸縮ビーム吊り具装置に関する。   The present invention relates to a telescopic beam hanging device provided with a telescopic beam used for transporting building materials and the like with a crane.

伸縮ビームを備えた吊り具装置として、長さが異なる３個の伸縮ブーム（ビーム）を備え、各ブームを伸縮するためにブームにローラーが内設され、各ローラーの下部にクランプを設けた吊り具装置が公知である。（特許文献１参照）
特開平８−１８９１９６号公報 As a lifting device equipped with telescopic beams, there are three telescopic booms (beams) of different lengths, and each boom is provided with a roller in order to expand and contract each boom, and a clamp is provided below each roller. The device is known. (See Patent Document 1)
JP-A-8-189196

前記特許文献１に記載された吊り具では、伸縮ビームの両端のクランプは固定され、その他のクランプはローラーの下部に設けられており、並設された長さの異なる３個のビームを伸縮することで、クランプを等間隔で伸縮する構造となっており、ローラーは隣接するビームの下部側板を転動するため、伸縮ビーム間にはビームを構成する側板の厚さ分だけ段差があり、そのため伸縮されるビーム間にはクランプの高さに寸法の差が生ずるという課題を有していた。   In the hanging device described in Patent Document 1, the clamps at both ends of the telescopic beam are fixed, and the other clamps are provided at the lower part of the roller, and extend and contract the three beams having different lengths arranged side by side. Therefore, the clamp has a structure that expands and contracts at equal intervals, and the roller rolls on the lower side plate of the adjacent beam, so there is a step between the expandable beams by the thickness of the side plate that constitutes the beam. There has been a problem that a difference in size occurs in the height of the clamp between the expanded and contracted beams.

また、スライドビームの伸縮作業時に、ローラーが他のビームに乗り移る際には、ビームの段差によりガタが生じ、円滑なビームの伸縮作業の支障になり、また、スライドビームの左右方向及び上下方向の位置を固定する手段がないので、スライドビーム間に緩みが生じ、さらに、クランプ位置がビームの段差の部分になった場合にはクランプ位置が安定しないという課題を有していた。   In addition, when the roller moves to another beam during the expansion / contraction operation of the slide beam, the step of the beam generates a backlash, which hinders the smooth expansion / contraction operation of the beam. Since there is no means for fixing the position, looseness occurs between the slide beams. Further, when the clamp position is a stepped portion of the beam, the clamp position is not stable.

本発明の前記課題を解決するもので、主ビームと、主ビームの底面にスライド可能に並設され、互いに対向して逆方向にスライドする２本のスライドビームを備え、前記スライドビームに、主ビームから下方に突出する突出部を設け、前記突出部にスライドビームの伸縮ピッチ幅と合致した間隔のフック取付け穴を設けたことを特徴とする。   In order to solve the above-mentioned problems of the present invention, a main beam and two slide beams that are slidably arranged on the bottom surface of the main beam and slide in opposite directions to each other are provided. Protruding portions projecting downward from the beam are provided, and hook attaching holes having an interval matching the expansion / contraction pitch width of the slide beam are provided in the projecting portion.

また、スライドビームは、角パイプの一方の側面に固着される対向側板と他方の側面に固着される外側側板を有し、対向側板は、他方のスライドビームの対向側板と対向し、かつ主ビームから下方に突出し、フック取付け穴を設けた突出部を有し、両スライドビームの対向側板のフック取付け穴を合致させ、フック取付け穴にフックを係着するようにしたことを特徴とする。   The slide beam has an opposite side plate fixed to one side surface of the square pipe and an outer side plate fixed to the other side surface, the opposite side plate is opposed to the opposite side plate of the other slide beam, and the main beam. And projecting downwardly, and having a hook mounting hole, the hook mounting holes of the opposite side plates of both slide beams are matched, and the hook is engaged with the hook mounting hole.

また、主ビームは、端部にスライドビーム側面に摺接するガイドローラーとスベリ軸受けと、前記ビームの上面及び下面に摺接するスベリ軸受けを有し、スライドビームは、主ビームに常時内接する側の端部に、主ビームの内側上面に摺接するガイドローラーと内側下面に摺接するスベリ軸受けと、主ビームの内側側面に摺接するガイドローラーと他方のスライドビームの側面に摺接するガイドローラーを有することを特徴とする。   The main beam has a guide roller and a sliding bearing that are in sliding contact with the side surface of the slide beam at the end, and a sliding bearing that is in sliding contact with the upper and lower surfaces of the beam. The sliding beam is an end on the side that is always inscribed in the main beam. And a guide roller that slides on the inner upper surface of the main beam, a sliding bearing that slides on the inner lower surface, a guide roller that slides on the inner side surface of the main beam, and a guide roller that slides on the side surface of the other slide beam. And

また、スライドビームは、スライドビームの伸縮ピッチ幅に合致した間隔で設けた挿通孔を有し、前記挿通孔を主ビームに設けた固定ピン挿通孔に合致させ、固定ピンを前記挿通孔に嵌挿し、主ビームとスライドビームを固定したことを特徴とする。   The slide beam has insertion holes provided at intervals matching the expansion / contraction pitch width of the slide beam, the insertion holes are matched with the fixed pin insertion holes provided in the main beam, and the fixed pins are fitted into the insertion holes. It is characterized in that the main beam and the slide beam are fixed.

本発明によると、主ビームと、主ビームの底面にスライド可能に並設され、互いに対向して逆方向にスライドする２本のスライドビームを備え、前記スライドビームに、主ビームから下方に突出する突出部を設け、前記突出部にスライドビームの伸縮ピッチ幅と合致した間隔のフック取付け穴を設けた構成とすることで、スライドビームは主ビームの底面にスライド可能に並設されて、かつ、フック取付け穴はスライドビームの下部に設けられているため、各スライドビームのフック取付位置に高さ寸法の差はなく、正確に吊り具によって被搬送物を吊り上げまたは吊り下げて搬送することができ、また、両スライドビームの伸縮動作時においてガタが生ぜず、また、スライドビームの伸縮ピッチとフック取り付け穴のピッチ間隔が同じであるため、両スライドビームを並列した状態で、フック取り付け穴を合致してフックを取り付けることで、両スライドビームをより確実に固定することができる。   According to the present invention, the main beam and two slide beams that are slidably arranged on the bottom surface of the main beam and that slide in opposite directions to each other are provided, and the slide beam protrudes downward from the main beam. Providing a protrusion, and by providing a hook attachment hole with an interval matching the expansion and contraction pitch width of the slide beam in the protrusion, the slide beam is slidably arranged on the bottom surface of the main beam, and Since the hook mounting hole is provided at the bottom of the slide beam, there is no difference in height at the hook mounting position of each slide beam, and the object to be transported can be accurately lifted or suspended by a lifting tool. In addition, there is no backlash when the slide beams extend and retract, and the slide beam expansion pitch and the hook mounting hole pitch interval are the same. Therefore, in a state in parallel both slide beam, by attaching the hook consistent hook mounting hole, it is possible to fix the both slide beam more reliably.

The opposite side plate faces the opposite side plate of the other slide beam, and from the main beam. It has a projecting part that protrudes downward and has hook mounting holes. The hook mounting holes on the opposite side plates of both slide beams are matched, and the hooks are engaged with the hook mounting holes. The position of can be fixed.
