Description

ボルト締め付け実習装置Bolt tightening training device
　本発明は、ボルト締め付け実習装置に関する。更に詳しくは、本発明は、配管同士の接続部のフランジ等の締結体をボルトで締め付ける際に適切なボルトの締め付けを実習することができるボルト締め付け実習装置に関する。本発明のボルト締め付け実習装置は、例えば、ボルトを締結体に締め付ける際のトルクの管理の教育講習、ボルトを締結体に締め付ける前の締め付けトルクの確認等の際に好適に使用することができる。 The present invention relates to a bolt tightening training apparatus. More specifically, the present invention relates to a bolt tightening training apparatus capable of practicing appropriate bolt tightening when tightening a fastening body such as a flange of a connection portion between pipes with a bolt. The bolt tightening training apparatus of the present invention can be suitably used for, for example, an education course on torque management when tightening a bolt to a fastening body, confirmation of a tightening torque before tightening a bolt to a fastening body, and the like.
　プラントの配管同士のフランジ等の締結体をボルトで締め付ける作業は、プラントを安全に操業させるために非常に重要な作業である。一般に配管同士のフランジのボルトによる締め付ける際には、トルク法による締付力の管理が行なわれており、締付力の管理には、トルクレンチが推奨される。 The work of tightening a fastening body such as a flange between pipes of a plant with a bolt is a very important work for operating the plant safely. In general, when tightening pipes with flange bolts, tightening force is managed by the torque method, and a torque wrench is recommended for tightening force management.
　しかし、トルクレンチは、高価であることから、数多くの作業者にトルクレンチを装備させることは経済的ではない。また、トルクレンチを用いる場合、フランジごとにトルクレンチのトルク値の設定を変更する必要があることから、作業効率に劣るという欠点がある。更に一般にトルクレンチは、ボルトにセットするボックス部分が障害となり、締め付け作業が困難となることがある。このため、配管同士のフランジのボルトによる締め付けは、多くの場合、トルクレンチを用いず、ハンドスパナ等を用いて現場の作業者の感覚で行なわれており、配管内に高圧の流体を使用するとき、危険性が高い流体を使用するとき等には、トルクレンチでトルク値を確認しながら締め付けが行なわれることがある（例えば、特許文献１の段落［００３５］、特許文献２の段落［００１８］、特許文献３の段落［００１２］及び特許文献４の段落［００３２］を参照）。 However, since a torque wrench is expensive, it is not economical to equip many workers with a torque wrench. Moreover, when using a torque wrench, since it is necessary to change the setting of the torque value of a torque wrench for every flange, there exists a fault that it is inferior to work efficiency. Furthermore, in general, a torque wrench may be difficult to tighten due to an obstacle in a box portion set on a bolt. For this reason, tightening of flanges between pipes with bolts in many cases is carried out with the use of a hand spanner or the like without using a torque wrench, and a high-pressure fluid is used in the pipes. When using a highly dangerous fluid, tightening may be performed while checking the torque value with a torque wrench (for example, paragraph [0035] of Patent Document 1 and paragraph [0018] of Patent Document 2). ], Paragraph [0012] of Patent Document 3 and paragraph [0032] of Patent Document 4.
　配管同士のフランジをボルトで締め付けた場合、目的とする締め付け力は、使用されるガスケットの種類、環境温度等によって異なるとともに、経時的な荷重の低下を見込んで締め付け荷重を与える必要がある。しかし、トルクレンチを用いずに締め付けを行なう場合、目的とする締め付け力に達成したことを確認することができなかったり、ボルトごとに締付け力にバラツキが生じたりすることがあるため、当該ボルトの締め付けには、かなりの熟練した技術が要求される。また、個々のフランジの締め付けのみならず入り組んだ配管の相互作用により、ミスアライメントが発生することがある。 When the flanges between pipes are tightened with bolts, the target tightening force differs depending on the type of gasket used, environmental temperature, etc., and it is necessary to apply a tightening load in anticipation of a decrease in load over time. However, when tightening without using a torque wrench, it may not be possible to confirm that the target tightening force has been achieved, or the tightening force may vary from bolt to bolt. Tightening requires considerable skill. Further, misalignment may occur due to the interaction of complicated piping as well as the tightening of individual flanges.
　更にハンドスパナによるボルトの締付力は、作業者の感覚によって行なわれており、作業者は、締付力と締め付けトルクとの関係を的確に把握することができないため、作業者間で締付力にバラツキが発生し、ボルトの締付力の過不足が生じる惧れがある。このことから、作業者は、ボルトの締め付け力を適切に調整することができる技術を身につける必要がある。 Furthermore, the bolt tightening force by the hand spanner is performed according to the operator's senses, and the operator cannot accurately grasp the relationship between the tightening force and the tightening torque. There is a possibility that the force will vary and the bolt tightening force will be excessive or insufficient. For this reason, the operator needs to acquire a technique capable of appropriately adjusting the tightening force of the bolt.
　従来、配管同士のフランジをボルトで締め付ける作業を学習するためには、熟練した作業者の指導のもとで実際に配管同士のフランジをボルトで締め付ける作業を行なうことが望まれる。しかし、近年、配管同士のフランジのボルトによる締め付けに熟練している技術者の減少傾向にあることから、熟練した作業者の指導のもとで学習することが困難になりつつある。 Conventionally, in order to learn the work of fastening flanges between pipes with bolts, it is desirable to perform the work of actually fastening flanges between pipes with bolts under the guidance of a skilled worker. However, in recent years, the number of engineers who are skilled in tightening flanges between pipes by bolts has been decreasing, and it has become difficult to learn under the guidance of skilled workers.
　従って、近年、ハンドスパナ等の締め付け工具を用いて配管同士のフランジ等の締結体をボルトで締め付ける際に、ボルトを締め付ける際の締付力と実際に締め付けたときのトルクとの関係を実習者に的確に把握させることができるボルト締め付け実習装置の開発が急務となっている。 Therefore, in recent years, when a fastening body such as a flange between pipes is tightened with a bolt using a tightening tool such as a hand spanner, the practitioner is in charge of the relationship between the tightening force when tightening the bolt and the torque when actually tightening. There is an urgent need to develop a bolt tightening training device that can be accurately grasped.

Characterized in that it comprises a display means for visualizing the data.
　本発明のボルト締め付け実習装置は前記構成を有するので、実習者は、熟練した作業者による指導がなくてもトルクレンチ、ハンドスパナ等の締め付け工具を用いて配管同士のフランジ等の締結体をボルトで締め付ける際に、実習者が感じるボルトの締付力と実際に締め付ける際のトルクとの関係を的確に実習することができる。また、実習者は、本発明のボルト締め付け実習装置を用いることにより、配管の接続部のフランジ等の締結体をボルトで締め付けるのに必要な技術を習得することができる。 Since the bolt tightening training apparatus according to the present invention has the above-described configuration, the trainer bolts a fastening body such as a flange between pipes using a tightening tool such as a torque wrench and a hand spanner without the instruction of a skilled worker. It is possible to accurately practice the relationship between the bolt tightening force felt by the trainee and the torque at the time of actual tightening. Moreover, the practitioner can acquire the technique necessary for tightening the fastening body such as the flange of the connecting portion of the pipe with the bolt by using the bolt tightening training apparatus of the present invention.
　本発明のボルト締め付け実習装置は、締結体をボルトで締め付ける際に適切なボルトの締め付けを実習させるためのボルト締め付け実習装置であり、ボルト締め付け練習手段と演算手段と表示手段とを備えている。 The bolt tightening training apparatus of the present invention is a bolt tightening training apparatus for training appropriate bolt tightening when tightening a fastening body with a bolt, and includes bolt tightening practice means, calculation means, and display means.
　締結体としては、例えば、プラント等の配管同士のフランジ等が挙げられるが、本発明は、かかる例示のみに限定されるものではない。 As the fastening body, for example, a flange between pipes of a plant or the like can be mentioned, but the present invention is not limited to such an example.
　締結体を締め付ける際に用いられる締め付け具としてボルトが用いられる。本発明のボルト締め付け実習装置は、ボルトのみならずナットを締め付ける実習をする際にも好適に使用することができる。従って、本明細書では、締め付け具として便宜上ボルトが記載されているが、当該ボルトの概念には、当該ボルトのみならずナットが包含される。 A bolt is used as a fastening tool used when fastening a fastening body. The bolt tightening training apparatus of the present invention can be suitably used for training to tighten not only bolts but also nuts. Therefore, in this specification, a bolt is described as a fastening tool for convenience, but the concept of the bolt includes not only the bolt but also a nut.
　本発明のボルト締め付け実習装置に使用することができる締め付け工具としては、例えば、トルクレンチをはじめ、ハンドスパナ、モンキーレンチ、メガネレンチ等が挙げられるが、本発明は、かかる例示のみに限定されるものではない。 Examples of the tightening tool that can be used in the bolt tightening training apparatus of the present invention include a torque wrench, a hand spanner, a monkey wrench, a spectacle wrench, and the like, but the present invention is limited only to such examples. It is not a thing.
　以下に本発明のボルト締め付け実習装置を図面に基づいて詳細に説明するが、本発明は、かかる図面に示される実施態様のみに限定されるものではない。 Hereinafter, the bolt tightening training apparatus of the present invention will be described in detail with reference to the drawings, but the present invention is not limited only to the embodiment shown in the drawings.
　図１は、本発明のボルト締め付け実習装置の一実施態様を示す概略説明図である。図１に示されるボルト締め付け実習装置は、主としてボルト締め付け練習手段１と演算手段５と表示手段６を備えている。 FIG. 1 is a schematic explanatory view showing an embodiment of the bolt tightening training apparatus of the present invention. The bolt tightening training apparatus shown in FIG. 1 mainly includes a bolt tightening practice means 1, a calculation means 5, and a display means 6.
　ボルト締め付け練習手段１は、トルク検知体３と、締め付け工具（図示せず）を取り付けるための工具取付け部２と、当該工具取付け部２に締め付け工具を取り付けて工具取付け部２を締め付けた際に発生する歪を検知するための歪ゲージ４とを有する。 The bolt tightening practice means 1 includes a torque detector 3, a tool mounting portion 2 for mounting a tightening tool (not shown), and a tightening tool attached to the tool mounting portion 2 to tighten the tool mounting portion 2. And a strain gauge 4 for detecting the generated strain.
　ボルト締め付け練習手段１において、トルク検知体３の一端に工具取付け部２が配設されており、トルク検知体３の他端が固定されている。トルク検知体３の外周面には、歪ゲージ４が取り付けられている。 In the bolt tightening practice means 1, the tool mounting portion 2 is disposed at one end of the torque detector 3, and the other end of the torque detector 3 is fixed. A strain gauge 4 is attached to the outer peripheral surface of the torque detector 3.
　工具取付け部２は、実際のボルトの締め付け作業に使用されるボルトに対応する形状及び大きさを有することが好ましい。工具取付け部２は、実際のボルトの締め付け作業に使用されるボルトと同様に、通常、その断面形状が六角形を有する。工具取付け部２は、実際のボルトの締め付け作業に準じて実習することができるようにするために、トルク検知体３に着脱可能に配設され、実際のボルトの締め付け作業に使用されるボルトに対応する形状及び大きさを有する工具取付け部と交換可能に構成されていてもよい。このように工具取付け部２をトルク検知体３に着脱可能にするとともに他の工具取付け部と交換可能に配設したとき、実際に使用されるボルトと同様の形状及び大きさを有する工具取付け部２に交換することにより、実習者は、実際のボルトの締め付け作業に即した実習をすることができる。 The tool mounting portion 2 preferably has a shape and a size corresponding to a bolt used for actual bolt tightening work. The tool mounting portion 2 generally has a hexagonal cross-sectional shape, similar to a bolt used for an actual bolt tightening operation. The tool mounting portion 2 is detachably disposed on the torque detector 3 so that it can be practiced according to actual bolt tightening work, and is used as a bolt used for actual bolt tightening work. It may be configured to be exchangeable with a tool mounting portion having a corresponding shape and size. When the tool mounting portion 2 is detachably attached to the torque detector 3 and is disposed so as to be exchangeable with other tool mounting portions, the tool mounting portion has the same shape and size as a bolt that is actually used. By exchanging for 2, the practitioner can practice in accordance with the actual bolt tightening operation.
　トルク検知体３の一端には工具取付け部２が配設されており、当該トルク検知体３の他端は、図示されていないが、固定配置されている。従って、工具取付け部２に締め付け工具を取り付け、例えば、図１に示される矢印Ａ方向（時計回り）に締め付け工具を回転させることによってボルトの締め付け操作を行なったとき、一端が固定配置されているトルク検知体３には応力が発生するため、トルク検知体３が変形する。トルク検知体３が変形することによって生じる歪は、締め付け工具を回転させることによってボルトの締め付け操作を行なう際の応力（トルク）と比例関係にある。 The tool mounting portion 2 is disposed at one end of the torque detector 3, and the other end of the torque detector 3 is fixedly arranged, although not shown. Accordingly, when a tightening tool is attached to the tool mounting portion 2 and, for example, the bolt is tightened by rotating the tightening tool in the direction of arrow A (clockwise) shown in FIG. 1, one end is fixedly arranged. Since torque is generated in the torque detector 3, the torque detector 3 is deformed. The distortion caused by the deformation of the torque detector 3 is proportional to the stress (torque) when the bolt is tightened by rotating the tightening tool.
　締め付け工具を回転させることによってボルトの締め付けを行なったとき、トルク検知体３に歪が発生する。当該発生した歪により、トルク検知体３の電気抵抗が変化することから、歪ゲージ４では、通電によってトルク検知体３の微弱な電圧変化を検知することができる。歪ゲージ４で検出された電圧の変化は、電気信号として電線（図示せず）を介して演算手段５に伝達される。 When the bolt is tightened by rotating the tightening tool, the torque detector 3 is distorted. Since the electrical resistance of the torque detector 3 changes due to the generated strain, the strain gauge 4 can detect a weak voltage change of the torque detector 3 by energization. The voltage change detected by the strain gauge 4 is transmitted as an electrical signal to the computing means 5 via an electric wire (not shown).
　演算手段５は、ボルト締め付け練習手段１の工具取付け部２を締め付ける際に発生した歪を歪ゲージ４で読み取ることによって得られた情報をデータ化させるための手段である。演算手段５では、歪ゲージ４から伝達された電気信号の強度（電圧）に基づいてトルク検知体３に加えられた応力が算出される。演算手段５として、例えば、コンピュータ等を好適に用いることができる。演算手段５でデータ化された応力のデータは、例えば、電子データとして電線（図示せず）を介して表示手段６に伝達される。 The calculation means 5 is means for converting the information obtained by reading the strain generated when the tool mounting portion 2 of the bolt tightening practice means 1 is tightened with the strain gauge 4 into data. In the calculation means 5, the stress applied to the torque detector 3 is calculated based on the strength (voltage) of the electrical signal transmitted from the strain gauge 4. As the calculation means 5, for example, a computer or the like can be suitably used. The stress data converted into data by the calculation means 5 is transmitted to the display means 6 through an electric wire (not shown) as electronic data, for example.
　表示手段６は、演算手段５でデータ化されたデータを視認化させるための手段である。表示手段６として、例えば、応力を具体的な数値として表示することができるデジタル液晶モニタ等のモニタを用いることができる。 The display means 6 is a means for visualizing the data converted into data by the calculation means 5. As the display means 6, for example, a monitor such as a digital liquid crystal monitor capable of displaying stress as a specific numerical value can be used.
　図２は、本発明のボルト締め付け実習装置の一実施態様を示す概略斜視図である。図２に示されるボルト締め付け実習装置では、その上面にトルク検知体３及び工具取付け部２が設けられており、工具取付け部２に締め付け工具７が取り付けられている。工具取付け部２は、ボルト締め付け実習装置の上面ではなく、側面に設けられていてもよい。 FIG. 2 is a schematic perspective view showing an embodiment of the bolt tightening training apparatus of the present invention. In the bolt tightening training apparatus shown in FIG. 2, the torque detector 3 and the tool attachment portion 2 are provided on the upper surface, and the tightening tool 7 is attached to the tool attachment portion 2. The tool attachment portion 2 may be provided on the side surface instead of the upper surface of the bolt tightening training apparatus.
　図２に示されるボルト締め付け実習装置の下部には、当該ボルト締め付け実習装置の取り付け台８が設けられており、ボルト締め付け実習装置と取り付け台８とはスタンドポール９ａ，９ｂ，９ｃ，９ｄを介して接続されている。図２に示されるスタンドポール９ａ，９ｂ，９ｃ，９ｄは、４本で構成されているが、１～３本で構成されていてもよい。 At the bottom of the bolt tightening training apparatus shown in FIG. 2, a mounting base 8 for the bolt tightening training apparatus is provided. The bolt tightening training apparatus and the mounting base 8 are connected via stand poles 9a, 9b, 9c, 9d. Connected. The stand poles 9a, 9b, 9c, and 9d shown in FIG. 2 are composed of four pieces, but may be composed of one to three pieces.
　スタンドポール９ａ，９ｂ，９ｃ，９ｄのいずれかに、ボルト締め付け実習装置の工具取付け部２が水平方向ないし図２に示されている垂直方向の任意の角度に回転するようにするために回転自在に設けられていることが好ましい。例えば、図２に示される実施態様では、スタンドポール９ａの下端に凹部（図示せず）が設けられ、スタンドポール９ｂの上端に凸部（図示せず）が設けられており、スタンドポール９ａの下端の凹部にスタンドポール９ｂの上端の凸部が挿入されている。スタンドポール９ａの下端の凹部とスタンドポール９ｂの上端の凸部とがボルト１０によって接続されており、当該ボルト１０を回転軸としてスタンドポール９ａを回転させることにより、ボルト締め付け実習装置を任意の角度に回転させることができる。このようにボルト締め付け実習装置が回転自在に取り付け台８に取り付けられている場合には、ボルト締め付け実習装置を任意の角度に回転させることにより、工具取付け部２をボルト締め付け実習装置の上面又は側面に配置させることができるので、実際のプラント等におけるボルトの締め付け作業の際の種々のボルトの取付け角度に対応することができるという利点がある。 Any one of the stand poles 9a, 9b, 9c, 9d is freely rotatable so that the tool mounting portion 2 of the bolt tightening training apparatus can be rotated at any angle in the horizontal direction or the vertical direction shown in FIG. Is preferably provided. For example, in the embodiment shown in FIG. 2, a recess (not shown) is provided at the lower end of the stand pole 9a, and a protrusion (not shown) is provided at the upper end of the stand pole 9b. A convex portion at the upper end of the stand pole 9b is inserted into the concave portion at the lower end. A concave portion at the lower end of the stand pole 9a and a convex portion at the upper end of the stand pole 9b are connected by a bolt 10. By rotating the stand pole 9a with the bolt 10 as a rotation axis, the bolt tightening training apparatus can be moved at any angle. Can be rotated. When the bolt tightening training apparatus is rotatably mounted on the mounting base 8 in this way, the tool mounting portion 2 can be rotated at an arbitrary angle so that the tool mounting portion 2 can be turned on the upper surface or the side surface of the bolt tightening training apparatus. Therefore, there is an advantage that it is possible to cope with various bolt mounting angles at the time of bolt tightening work in an actual plant or the like.
　ボルト締め付け実習装置が上下方向に移動可能とするために、スタンドポール９ａ，９ｂ，９ｃ，９ｄのいずれかに、ボルト締め付け実習装置が上下方向に移動可能とするための伸縮機構１１が設けられていることが好ましい。図２に示される実施態様では、スタンドポール９ｂの下端は、スタンドポール９ｃの上端の開口部内に伸縮可能に挿入され、スタンドポール９ｃの下端は、スタンドポール９ｄの上端の開口部内に伸縮可能に挿入されている。例えば、スタンドポール９ｂの伸縮は、スタンドポール９ｂの外周面及びスタンドポール９ｃの内周面にねじ山を形成しておき、スタンドポール９ｂとスタンドポール９ｃとをねじ嵌合させ、スタンドポール９ｂ又はスタンドポール９ｃを回転させることにより、行なうことができる。このようにボルト締め付け実習装置の高さを自在に調節することができるようにした場合、実際のボルトの締め付け作業の際の種々のボルトの取付け位置に対応することができる。 In order to allow the bolt tightening training apparatus to move in the vertical direction, an extension mechanism 11 is provided in any of the stand poles 9a, 9b, 9c, 9d to enable the bolt tightening training apparatus to move in the vertical direction. Preferably it is. In the embodiment shown in FIG. 2, the lower end of the stand pole 9b is inserted into the opening at the upper end of the stand pole 9c so as to be extendable and the lower end of the stand pole 9c is extendable into the opening at the upper end of the stand pole 9d. Has been inserted. For example, the expansion and contraction of the stand pole 9b is performed by forming a screw thread on the outer peripheral surface of the stand pole 9b and the inner peripheral surface of the stand pole 9c, and screwing the stand pole 9b and the stand pole 9c together. This can be done by rotating the stand pole 9c. In this way, when the height of the bolt tightening training apparatus can be freely adjusted, it is possible to cope with various bolt mounting positions in actual bolt tightening operations.
　表示手段６としては、例えば、デジタル表示装置等が挙げられる。デジタル表示装置を用いた場合には、演算手段でデータ化されたデータを具体的な数値でデジタル表示することができる。 Examples of the display means 6 include a digital display device. When a digital display device is used, the data converted into data by the calculation means can be digitally displayed with specific numerical values.
　なお、図２に示されるボルト締め付け実習装置においては、トルク検知体（図示せず）及び歪ゲージ（図示せず）は、いずれも内蔵されている。 In the bolt tightening training apparatus shown in FIG. 2, both a torque detector (not shown) and a strain gauge (not shown) are incorporated.
　以上のように構成される本発明のボルト締め付け実習装置を用いることにより、実習者が締め付け工具を回転させることによってボルトの締め付け操作を行なったとき、トルク検知体の外周面に取り付けられている歪ゲージにより、発生した歪を検知することができるので、実習者が実際に体感した応力と実際にボルトの締付力との関係を的確に実習することができる。従って、本発明のボルト締め付け実習装置を用いることにより、実習者は、締結体をボルトで締め付ける際に適切なボルトの締め付けをリアルタイムに把握することができるので、表示装置の表示画面を見ながらボルトを適切に締め付けるために必要な技術を容易に身につけることができる。 By using the bolt tightening training apparatus of the present invention configured as described above, when the trainee performs the bolt tightening operation by rotating the tightening tool, the strain attached to the outer peripheral surface of the torque detector.
