Description

この発明は、配管の取り付け、ガスケット交換等において、フランジ外周面の食い違いを合わせるために使用する治具に関するものである。  The present invention relates to a jig used for fitting a gap between flange outer peripheral surfaces in piping installation, gasket replacement, and the like.

従来は、配管の取り付け、ガスケット交換等において、フランジ外周面の食い違いを合わせるため、ボルト穴に工具の柄、または、L形に曲げた丸棒を差し込んでこじたり、工具の柄を打ち込んで回転させたり、また、フランジが大きくずれて、ボルト穴を利用できない場合や、合わせるのに大きな力が必要な時は、チエンブロック等を使用して配管を引き寄せるなどして合わせ、その具合は目視によっていた。  Conventionally, in order to match the discrepancy of the outer peripheral surface of the flange during pipe installation, gasket replacement, etc., a tool handle or a round bar bent into an L-shape is inserted into the bolt hole, and the tool handle is driven and rotated. If the bolt hole cannot be used due to a large displacement of the flange, or if a large force is required to match, adjust the condition by pulling the pipes using a chain block or the like. It was.

これは次のような欠点があった。
(イ)ボルト穴に工具の柄、または、L形に曲げた丸棒を差し込む方法は、大きな力が得られず、無理に力をいれると差し込んだものが外れる等の危険があり、特に、高所における作業の安全性に問題があった。
(ロ)工具の柄を打ち込んで回転させる方法は、機械的に合わせることはできるが、大きな力が得られず、時間がかかり、ある程度の経験が必要であった。
(ハ)チエンブロック等を使用して配管を引き寄せる方法は、段取り、そのための作業、かたづけ等に時間がかかり、狭所やチエンブロック等をかけるところのない場所では、非常に困難であった。
(ニ)フランジの合わせ具合を目視によっているため、正確性に欠けていた。
本発明は、これらの欠点を除くためになされたものである。
This has the following drawbacks.
(B) The method of inserting a handle of a tool or a round bar bent into an L shape into a bolt hole cannot obtain a large force, and there is a danger that the inserted item will come off if the force is applied. There was a problem with the safety of work in high places.
(B) The method of driving and rotating the handle of the tool can be mechanically matched, but a large force cannot be obtained, it takes time, and some experience is required.
(C) The method of drawing pipes using a chain block or the like is very difficult in a place where there is no narrow space or a place where a chain block or the like is applied.
(D) The accuracy of the flange alignment was poor because it was visually observed.
The present invention has been made to eliminate these drawbacks.

上記の欠点を除くため、円柱(2)に同じ二個のスリーブ(9),(9)を通し、それぞれにアーム(10),(10)を設け、その先端には回転可能な小アーム(11),(11)が付いたフランジストッパー(13),(13)を設ける。二個の小アーム(11),(11)は、先端部に突出したピン(12),(12)が取り付けられ、ともに同一面上で回転し、その面はアーム(10),(10)の回転面と平行である。当該円柱(2)の端部に二個のスリーブ(9),(9)のストッパー(3)を取り付け、他方には引き寄せボルト(6)が螺着されたネジスリーブ(1)が取り付けられ、引き寄せボルト(6)は、突出した引き寄せピン(5)が付いた引き寄せ部(4)と結合されて、軸を中心に回転はできるが抜けない構造になっており、反対側にはナット(7)が取り付けられている。また、小アーム(11),(11)のピン(12),(12)と引き寄せピン(5)は対向状態になっている構造のフランジ合わせ冶具である。  In order to eliminate the above disadvantages, the same two sleeves (9) and (9) are passed through the cylinder (2), and arms (10) and (10) are provided respectively, and a small arm (at the tip thereof) that can be rotated ( 11) Provide flange stoppers (13) and (13) with (11). The two small arms (11) and (11) are provided with pins (12) and (12) protruding at the tip, and both rotate on the same plane, and the planes are the arms (10) and (10). Parallel to the plane of rotation. The stopper (3) of the two sleeves (9) and (9) is attached to the end of the cylinder (2), and the screw sleeve (1) to which the drawing bolt (6) is screwed is attached to the other, The pulling bolt (6) is coupled to the pulling portion (4) with the protruding pulling pin (5), and has a structure that can rotate around the shaft but cannot be removed. ) Is attached. Further, the pins (12), (12) of the small arms (11), (11) and the pulling pin (5) are flange fitting jigs having a structure in which they are opposed to each other.

フランジのボルト穴から相手フランジのボルト穴が見える場合は勿論のこと、フランジ相互が大きくずれてボルト穴を利用できない場合でも、チエンブロック等を使用すること無く、機械的にフランジ外周面を正確、かつ簡単にフランジの食い違いを大きな力で合わす事ができる。特に、狭所においては有効である。これにより、作業の時間短縮、および安全性の向上から、配管の取り付け、ガスケット交換等において、コストダウンを図る事ができる。  Even if the bolt hole of the mating flange can be seen from the bolt hole of the flange, even if the flange hole is greatly displaced and the bolt hole cannot be used, the flange outer peripheral surface can be mechanically accurately detected without using a chain block, And it is possible to easily match the discrepancy between the flanges with great force. This is particularly effective in narrow spaces. As a result, it is possible to reduce costs in the installation of pipes, the replacement of gaskets, etc., because work time is shortened and safety is improved.

以下、本発明を実施するための最良の形態について説明する。
円柱(2)に同じ二個のスリーブ(9),(9)を通し、それぞれにアーム(10),(10)を設け、その先端には回転可能な小アーム(11),(11)が付いたフランジストッパー(13),(13)を設ける。(図1)
