Description

本発明は、地震等により橋桁等が橋脚から落下するのを防止するための、落橋防止ブロック取付け装置に関するものである。   The present invention relates to a falling bridge prevention block mounting device for preventing a bridge girder or the like from falling from a pier due to an earthquake or the like.

一般に、図5に示すように、橋桁Kに鋼製ブラケットSを取り付けると共に、橋脚LにコンクリートブロックBを取り付けて、地震時等において橋桁K等が橋脚Lから落下するのを防止する対策が行われている。   In general, as shown in FIG. 5, a steel bracket S is attached to the bridge girder K, and a concrete block B is attached to the pier L to take measures to prevent the bridge girder K and the like from dropping from the pier L during an earthquake or the like. It has been broken.

従来、上記コンクリートブロックを橋脚に取り付ける技術としては、桁下にアンカーを打設して、これにチェーンブロックを取り付け、該チェーンブロックにより上記コンクリートブロックを上げて所定の位置近くまで運び上げ、宙吊り状態で人力により取付位置まで移動させ、予め橋脚に取り付けたアンカーボルトにコンクリートブロックの穴の位置を合わせて差込み橋脚に取り付けていた。
また従来、図6に示すように、クレーンのブームMの先端部に取付治具Nを設けて、この取付治具NにコンクリートブロックBをセットし、上記ブームにより調整しながらブロックを橋脚の取付位置まで移動させる技術があった。(例えば、特許文献1参照)
Conventionally, as a technique for attaching the concrete block to the pier, an anchor is placed under the girder, a chain block is attached to the anchor, the concrete block is raised by the chain block and carried to a predetermined position, and suspended in the air. It was moved to the mounting position by human power, and the hole of the concrete block was aligned with the anchor bolt that was previously mounted on the pier, and was attached to the pier.
Conventionally, as shown in FIG. 6, a mounting jig N is provided at the tip of a crane boom M, a concrete block B is set on the mounting jig N, and the block is attached to the pier while adjusting with the boom. There was a technology to move to a position. (For example, see Patent Document 1)

しかし、上記チェーンブロックによる取付は、コンクリートブロックの重量物を頭上のクリアランスのない狭隘な空間でしかも不安定な状態で移動させてボルト穴に合わせなければならないので、危険な苦渋作業で時間がかかるだけでなく、別途作業用の足場を組む必要があったり、ブロックにワイヤを掛けていたため、ブロックが欠けたりして品質の低下を生じさせる等の問題があった。   However, the installation with the above chain block requires moving the heavy load of the concrete block in a narrow space with no overhead clearance and in an unstable state, so that it must be aligned with the bolt hole, which is dangerous and difficult to work. In addition to this, there is a problem in that it is necessary to separately assemble a scaffold for work or a wire is hung on the block, so that the block is missing and the quality is deteriorated.

また、上記特許文献1のクレーンブームMの先端部の取付治具Nによる場合は、ブロックの位置および姿勢の調整が困難で手間と時間がかかるだけでなく、ブロック毎にクレーンを移動させなければならなかった。また、足場を必要とするだけでなく、ブームとの干渉を防止するために、足場の手摺りを撤去する必要があって危険な作業となる等の問題点もあった。
特開平11−147691号公報
Further, in the case of using the attachment jig N at the tip of the crane boom M of Patent Document 1, it is difficult to adjust the position and posture of the block, which takes time and labor, and the crane must be moved for each block. did not become. In addition to requiring a scaffold, there is also a problem that it is necessary to remove the handrail of the scaffold in order to prevent interference with the boom, which is a dangerous work.
JP-A-11-147691

The front / rear slide deck, the elevating frame provided on the front / rear slide deck via an elevating means, and a block set that can be mounted on the elevating frame so that the posture can be controlled and the block can be set detachably And a frame. Further, the present invention is characterized in that a mounting jig is fixed to the block set frame and the steel bracket is detachably set. Further, the elevating means is a pantograph type elevating means. Still further, the block set frame is attached to the elevating frame so that the posture can be controlled by a three-point supported posture control bolt.

本発明の落橋防止ブロック取付け装置は、ブロックの取付に際して位置や姿勢の調整を高精度で能率良く行うことができ、また、足場が不要で安全に取付作業を行うことができる、という利点がある。   The falling bridge prevention block mounting device of the present invention has the advantage that the position and posture can be adjusted with high accuracy and efficiency at the time of mounting the block, and the mounting work can be safely performed without a scaffold. .

図1は、本発明の取付装置を搭載する高所作業車を示すもので、1は俯仰および旋回自在で伸縮可能なブーム、2はブーム1の先端部に設けた作業デッキである。該作業デッキ2は旋回軸2aにより旋回可能となっている。また、デッキ2の周囲には手摺り2bが設けられている。3はアウトリガーである。   FIG. 1 shows an aerial work vehicle equipped with a mounting device according to the present invention, wherein 1 is a boom that can be lifted and swung freely and expandable and contractable, and 2 is a work deck provided at the tip of the boom 1. The work deck 2 can be turned by a turning shaft 2a. A handrail 2 b is provided around the deck 2. 3 is an outrigger.

図2は、本発明のブロック取付け装置の一実施例を示すもので、仮想線で示す上記作業デッキ2上に設置されている前後スライドデッキ2−2上に搭載されている。該ブロック取付け装置は、主として装置取り付けフレーム4と、昇降手段7と、昇降フレーム8と、ブロックセットフレーム9から構成されている。   FIG. 2 shows an embodiment of the block mounting apparatus of the present invention, which is mounted on the front / rear slide deck 2-2 installed on the work deck 2 indicated by a virtual line. The block mounting device mainly includes a device mounting frame 4, a lifting / lowering means 7, a lifting / lowering frame 8, and a block set frame 9.

上記昇降手段7は、上記装置固定フレーム6と上記昇降フレーム8の間に設けられ、パンタグラフ式に構成されており、例えば油圧駆動手段7a(図2(B)を参照)により昇降フレーム8を上下方向(矢印Z)に往復移動(昇降)するようになっている。7bは操作杆である。   The elevating means 7 is provided between the device fixing frame 6 and the elevating frame 8 and is configured in a pantograph manner. For example, the elevating frame 8 is moved up and down by a hydraulic drive means 7a (see FIG. 2B). It reciprocates (lifts) in the direction (arrow Z). Reference numeral 7b denotes an operation rod.

上記ブロックセットフレーム9は、3点支持の姿勢制御ボルト9aを介して、上記昇降フレーム8上に姿勢(傾き)制御可能に取り付けられている。3つの姿勢制御ボルト9aを調整することにより、上記ブロックセットフレーム9の姿勢、すなわち水平に対する傾きが調整される。該ブロックセットフレーム9上には、ブロックをセットするための固定枠9bが立設されている。   The block set frame 9 is mounted on the lift frame 8 via a three-point supported posture control bolt 9a so that the posture (tilt) can be controlled. By adjusting the three posture control bolts 9a, the posture of the block set frame 9, that is, the inclination with respect to the horizontal is adjusted. On the block set frame 9, a fixed frame 9b for setting a block is erected.
