Description
本発明は、溶接訓練用治具に関する。 The present invention relates to a welding training jig.
2つの管体の端部同士を突き合わせた状態で2つの管体の開先を溶接する技術が提案されている(例えば特許文献1参照)。この種の溶接技術は、工場、発電所等における配管の敷設工事において利用されている。また、このような配管の敷設工事における配管同士の溶接は、溶接装置を利用した自動化も進んでいるが、依然として溶接士による手溶接により行われることが多い。特に、比較的狭隘な場所に設置された配管同士の溶接のように溶接装置の配置が困難な場所での溶接は、熟練した溶接士により行われるのが現状である。 A technique has been proposed in which the groove of the two pipes is welded in a state where the ends of the two pipes are butted against each other (for example, see Patent Document 1). This kind of welding technology is used in the laying work of piping in factories, power plants and the like. Further, the welding of the pipes in such a laying work of the pipes is being automated by using a welding device, but it is still often manually performed by a welder. In particular, welding is currently performed by a skilled welder in a place where welding equipment is difficult to arrange, such as welding between pipes installed in a relatively narrow place.
ところで、工業、発電所等における設備の複雑化または省スペース化に伴い、比較的狭隘な場所に設置された配管同士の溶接の需要が高まりつつある。そのため、熟練した溶接士の育成が求められている。そして、溶接士の育成のために、実際に高度な溶接技能が要求される場所を再現して溶接訓練を行える環境の構築が要請されつつある。 By the way, demand for welding between pipes installed in relatively narrow places is increasing due to the complexity of equipment and space saving in industries, power plants, and the like. Therefore, training of skilled welders is required. In order to train welders, there is a demand for the construction of an environment in which welding training can be performed by reproducing the place where advanced welding skills are actually required.
本発明は、上記事由に鑑みてなされたものであり、高度な溶接技能が要求される場所を再現できる溶接訓練用治具を提供することを目的とする。 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a welding training jig capable of reproducing a place where high welding skill is required.
上記目的を達成するために、本発明に係る溶接訓練用治具は、
2つの管体を溶接する訓練を行うための溶接訓練用治具であって、
複数の第1管体を、前記複数の第1管体それぞれの筒軸方向に直交する一方向に並列した状態で支持する第1支持部材と、
複数の第2管体を、前記複数の第1管体それぞれの筒軸方向において前記複数の第1管体それぞれに隣接し、前記複数の第2管体それぞれの筒軸方向に直交する一方向に並列した状態で支持する第2支持部材と、
前記複数の第1管体および前記複数の第2管体に対向して配置されたパネルと、を備え、
前記第2支持部材は、前記複数の第1管体それぞれの前記複数の第2管体側の第1端部と前記複数の第2管体それぞれの前記複数の第1管体側の第2端部とが突き合わされ、前記第1端部および前記第2端部と前記パネルとの間の距離が50mm以上110mm以下の長さとなるように前記複数の第2管体を支持する。

支持部材11は、長尺の角柱状でありX軸方向に延在する梁部112と、梁部112の長手方向に沿って配設され管体TU1を保持する5つの保持部111と、を有し、5つの管体TU1をX軸方向に並列した状態で支持する第1支持部材である。 The support member 11 includes a beam portion 112 that is a long prism and extends in the X-axis direction, and five holding portions 111 that are arranged along the longitudinal direction of the beam portion 112 and that hold the tubular body TU1. It is a first support member having and supporting five tubular bodies TU1 in a state of being aligned in the X-axis direction.
保持部111は、図2(B)に示すように、梁部112に固定される基台1111と、長尺であり長手方向の一端部が基台1111に軸部1116を介して旋回自在に軸支されたアーム1112と、フック1113と、を有する。ここで、基台1111には、管体TU1が載置される溝1111aが形成されている。また、フック1113は、長尺であり、中央部に湾曲部1113bを有する。このフック1113は、長手方向の一端部がアーム1112の他端部に軸部1117を介して旋回自在に軸支され、他端部にスリット1113aが形成されている。また、保持部111は、棒状であり一部に螺子部1114aが設けられるとともに、長手方向の一端部が軸部1118を介して基台1111に旋回自在に軸支された留め具1114と、留め具1114の螺子部1114aに螺着したナット1115と、を有する。この保持部111は、図2(B)の一点鎖線で示すように、基台1111の溝1111aに管体TU1が嵌入された状態でフック1113の湾曲部1113bの内側に管体TU1が配置される形でフック1113を基台1111に被さった状態で、管体TU1を保持する。このとき、フック1113のスリット1113aに留め具1114を嵌入した状態で、留め具1114の螺子部1114aに螺着されたナット1115を締め込むことにより管体TU1が基台1111に堅固に固定される。管体TU1が保持部111に保持された状態で、ナット1115を緩めてから、図2(B)の矢印AR1に示すように留め具1114を軸部1118周りに旋回させ、その後、図2(B)の矢印AR2に示すように、フック1113を軸部1117周りに旋回させることにより、管体TU1を保持部111から取り外し可能な状態とすることができる。これにより、管体TU1が、支持部材11に対して着脱自在となっている。 As shown in FIG. 2(B), the holding portion 111 has a base 1111 fixed to the beam portion 112, and a long one end portion in the longitudinal direction which is rotatable on the base 1111 via a shaft portion 1116. It has a pivotally supported arm 1112 and a hook 1113. Here, the base 1111 is formed with a groove 1111a in which the tubular body TU1 is placed. The hook 1113 is long and has a curved portion 1113b at the center. One end of the hook 1113 in the longitudinal direction is rotatably supported by the other end of the arm 1112 via a shaft 1117, and a slit 1113a is formed at the other end. Further, the holding portion 111 is rod-shaped, a screw portion 1114a is partially provided, and one end portion in the longitudinal direction is pivotally supported by the base 1111 via a shaft portion 1118, and a fastener 1114.

The tubular body TU1 is held in a state in which the base 1111 is covered with the hook 1113 in a bent shape. At this time, the tubular body TU1 is firmly fixed to the base 1111 by tightening the nut 1115 screwed to the screw portion 1114a of the fastener 1114 with the fastener 1114 fitted in the slit 1113a of the hook 1113. . With the tubular body TU1 held by the holding portion 111, the nut 1115 is loosened, and then the fastener 1114 is swung around the shaft portion 1118 as shown by an arrow AR1 in FIG. By rotating the hook 1113 around the shaft portion 1117 as shown by the arrow AR2 in B), the tubular body TU1 can be made detachable from the holding portion 111. As a result, the tubular body TU1 is detachable from the support member 11.
図1(A)に戻って、支持部材12は、長尺の角柱状でありX軸方向に延在する梁部122と、梁部122の長手方向に沿って配設され管体TU2を保持する5つの保持部121と、を有する第2支持部材である。保持部121は、保持部111と同様の構成である。これにより、管体TU2が、支持部材12に対して着脱自在となっている。支持部材12は、5つの管体TU2を、Z軸方向において管体TU1に隣接し、X軸方向に並列した状態で支持する。支持部材12は、管体TU1の+Z方向側の端部TU1aと管体TU2の−Z方向側の端部TU2aとが突き合わされた状態で、管体TU2を支持する。ここで、管体TU1の端部TU1aが、管体TU2の端部TU2aに溶接される第1端部であり、管体TU2の端部TU2aが、管体TU1の端部TU1aに溶接される第2端部である。また、梁部112、122は、それらの長手方向における両端部それぞれが柱24に固定されている。 Returning to FIG. 1(A), the support member 12 is a long prism and has a beam portion 122 extending in the X-axis direction and a tubular body TU2 arranged along the longitudinal direction of the beam portion 122. It is a 2nd support member which has five holding parts 121 which do. The holding unit 121 has the same configuration as the holding unit 111. As a result, the tubular body TU2 is attachable to and detachable from the support member 12. The support member 12 supports the five tubular bodies TU2 adjacent to the tubular body TU1 in the Z-axis direction and in parallel with each other in the X-axis direction. The support member 12 supports the tubular body TU2 in a state where the end portion TU1a on the +Z direction side of the tubular body TU1 and the end portion TU2a on the −Z direction side of the tubular body TU2 are butted against each other.

The tubular body TU2 is supported so that the distance between the end portions TU3a, TU4a of the tubular bodies TU3, TU4 and the panel 18 is 50 mm or more and 110 mm or less. As a result, the distance between the end TU3a of the tubular body TU3 and the end TU4a of the tubular body TU4, which are welded to each other, and the ground F is approximately the same as the external dimensions of the welding torch To having a general size. Therefore, it is possible to reproduce the environment in which the tubular bodies TU3 and TU4 laid near the ground F are welded to each other, which requires a high degree of skill.
