Description

本発明は、トンネル建設工事現場の支保工の建込み作業において、さく孔機械のガイドシェル上で支保工をクランプするための支保工キャッチャーに関するものである。   The present invention relates to a support work catcher for clamping a support work on a guide shell of a drilling machine in a work of installing a support work at a tunnel construction work site.

一般に、トンネル建設工事では、切羽にドリルジャンボやクローラドリル等のさく孔機械で発破孔をさく孔して、岩盤を破砕し掘削した後、H鋼製の支保工を建込む。
図4に示すように、さく孔機械10は走行台車12上に旋回起伏可能なさく孔ブーム14を備えており、このさく孔ブーム14の先端部に、ガイドマウンチング16を介して、さく岩機18を搭載したガイドシェル20が支持されている。ガイドシェル20にはフィードシリンダ(図示略)が内蔵されており、さく岩機18をガイドシェル20上で前後に移動させることができる。さく岩機18には、先端にビット19Bを取り付けたロッド19が挿着されている。
Generally, in tunnel construction work, a blasting hole is drilled on the face with a drilling machine such as a drill jumbo or a crawler drill, the rock mass is crushed and excavated, and then a support made of H steel is installed.
As shown in FIG. 4, the drilling machine 10 includes a drilling boom 14 that can turn up and down on a traveling carriage 12, and a drilling rock 14 is inserted into the drilling boom 14 via a guide mounting 16. A guide shell 20 carrying the machine 18 is supported. A feed cylinder (not shown) is built in the guide shell 20, and the rock drill 18 can be moved back and forth on the guide shell 20. A rod 19 having a bit 19B attached to the tip is inserted into the rock drill 18.

さく孔作業時には、さく孔ブーム14でガイドシェル20を移動させて所定のさく孔位置に位置決めし、さく岩機18でロッド19に打撃と回転を与えると共に、フィードシリンダでさく岩機18に送りを与えて、切羽に発破孔をさく孔する。
支保工の建込み作業時には、エレクター台車が用いられる(特許文献1参照)。
しかし、比較的規模の小さいトンネル建設工事などでは、さく孔機械に加えてエレクター台車まで準備するのは設備経費が嵩むため望ましくない。
At the time of drilling work, the guide shell 20 is moved by the drill boom 14 to be positioned at a predetermined drill hole position, and the rod 19 is blown and rotated by the drill rocker 18 and sent to the drill rocker 18 by the feed cylinder. And drill a blast hole in the face.
An erector cart is used during the construction work of the support work (see Patent Document 1).
However, in the construction of a relatively small tunnel or the like, it is not desirable to prepare an erector carriage in addition to the drilling machine because the equipment costs increase.

そこで、さく孔機械10のガイドシェル20に支保工の載置具を設けて、支保工をガイドシェル20上に載せ、さく孔ブーム14でガイドシェル20を移動させて支保工を所定の建込み位置まで運び、建込みを行うことがある。
ところが、支保工の載置具は、単に支保工をガイドシェル20上に載せるだけのものであり、ガイドシェル20で持ち上げて移動させ建込む間に、支保工が位置ずれし載置具から外れるおそれがあり、安全性に欠ける。
Therefore, a supporting tool is placed on the guide shell 20 of the drilling machine 10, the supporting work is placed on the guide shell 20, and the guide shell 20 is moved by the drilling boom 14 to set the supporting work in a predetermined manner. May be carried to a location and built.
However, the support tool is simply for placing the support work on the guide shell 20, and the support work is displaced and detached from the support tool while the guide shell 20 is lifted, moved, and built. There is a fear, it is not safe.

これに対し、特許文献1記載のエレクター台車の支保工建込み用ブームに設けられているような開閉可能な支保工キャッチャーをガイドシェル20に設ければ、支保工をガイドシエル20上で位置ずれしないようにクランプ可能となるが、そのためにはガイドシェル20に新たに油圧シリンダ等の装置を取付ける必要があり、コストが高くなるうえ、さく孔作業の邪魔になるので作業能率が低下する。
特開平6−212897号公報
On the other hand, if the guide shell 20 is provided with an openable and closable support catcher as provided in the boom for supporting construction of the erector cart described in Patent Document 1, the support work is displaced on the guide shell 20. However, in order to do so, it is necessary to newly attach a device such as a hydraulic cylinder to the guide shell 20, which increases the cost and hinders the drilling operation, thereby reducing the work efficiency.
