Description

本発明は、請求項１のプリアンブルまたは請求項７のプリアンブルによる管状連結器に関する。   The present invention relates to a tubular connector according to the preamble of claim 1 or the preamble of claim 7.

特許文献１から、ゴム弾性材料からなるスリーブを有し、このスリーブが２本の管の端部間のギャップの封止に利用される、２本の管の端部を連結するための管状連結器が知られている。特許文献１によれば、このスリーブは、軸方向のリングチャンバ内でシェルの内側に配設されており、緊定装置を用いてシェルを、したがってスリーブを緊定することができる。この従来技術において、この緊定装置は、２つの緊定バンドを含み、各緊定バンドと緊定ネジとが協働する。このように特許文献１によれば、両方の緊定バンドの端部は、ループ状に曲げられており、緊定バンドそれぞれの一方の端部それぞれは、丸ボルトとして形成された緊定ボルトを取り囲む。それぞれの緊定バンドと協働する緊定ネジは、緊定バンドそれぞれにおいてループ状に曲げられた端部を取り囲む丸ボルトを通って延びる。   From Patent Document 1, a tubular connection for connecting the ends of two pipes having a sleeve made of a rubber elastic material, which is used for sealing a gap between the ends of the two pipes The vessel is known. According to U.S. Pat. No. 6,057,059, this sleeve is arranged inside the shell in an axial ring chamber and can be tightened with a tensioning device. In this prior art, the tensioning device includes two tensioning bands, with each tensioning band and tensioning screw cooperating. As described above, according to Patent Document 1, the ends of both of the tightening bands are bent in a loop shape, and one end of each of the tightening bands has a tightening bolt formed as a round bolt. surround. A tightening screw that cooperates with each tightening band extends through a round bolt that surrounds the looped end of each tightening band.

緊定バンドのループ状に曲げられた端部は、原理的に２つの区間すなわち巻回区間ならびに連結区間に分けられ、巻回区間は、丸ボルトそれぞれの巻き回しに利用され、ループ状に曲げられた端部は、連結区間で緊定バンドの外側と堅牢に連結される。特許文献１によれば、緊定バンドのループ状に曲げられた端部の連結区間は、溶接スポットによって緊定バンドそれぞれの外側と固定連結されており、この連結区間は、巻回区間に対して角度を付けて曲げられている。
ドイツ実用新案第８９１６０３１号 The end of the tension band bent in a loop shape is divided into two sections, that is, a winding section and a connecting section. The winding section is used for winding round bolts and bent into a loop. The formed end portion is firmly connected to the outside of the tension band in the connection section. According to Patent Document 1, the connecting section of the end portion of the tension band bent in a loop shape is fixedly connected to the outside of each of the tension bands by a welding spot. Is bent at an angle.
German utility model 8916031

この現況技術から知られる管状連結器は、動的負荷により、緊定バンドにおけるループ状に曲げられた端部の連結区間に亀裂形成が生じ得るという欠点を有する。このため、最終的に管状連結器が外れ、２本の連結された管の隣接する端部間のギャップがもはや封止できなくなることが生じ得る。この点から出発して、本発明の基礎となる課題は、新規方式の管状連結器を提供することである。   The tubular coupler known from this state of the art has the disadvantage that cracking can occur in the connecting section of the looped end of the tightening band due to dynamic loading. This can eventually cause the tubular connector to come off and the gap between adjacent ends of the two connected tubes can no longer be sealed. Starting from this point, the problem underlying the present invention is to provide a new type of tubular coupler.

この課題は、本発明の第１の形態によれば、請求項１記載の管状連結器によって解決される。それによれば、前記緊定バンドまたは各緊定バンドの外側に接触する、各端部の巻回区間と連結区間の間の移行領域が、各緊定バンドの外側に対して接線方向に走り、該緊定バンドがそれを介して各緊定バンドの外側と固定連結されている、前記緊定バンドまたは各緊定バンドの各端部の連結区間が、各緊定ボルトから見て移行領域の後方に位置するように、前記緊定バンドまたは各緊定バンドのループ状に曲げられた各端部が、各緊定バンドの外側で接線方向に担持される。   This problem is solved according to the first aspect of the invention by the tubular coupler according to claim 1. According to it, the transition area between the winding section and the connecting section of each end, which contacts the outside of each of the tension bands or each tension band, runs tangentially to the outside of each tension band, The tightening band or a connection section of each end of each tightening band, to which the tightening band is fixedly coupled to the outside of each tightening band, has a transition region as viewed from each tightening bolt. The end portions of the tension band or each tension band bent in a loop shape are tangentially supported outside the tension band so as to be located rearward.

本発明の第２の態様によれば、この課題は、請求項７記載の管状連結器によって解決される。それによれば、スリーブが区間ごとに成形殻体によって取り囲まれており、この成形殻体で緊定装置の少なくとも１つの緊定要素が担持され、緊定装置が成形殻体を介してスリーブを緊定する。   According to a second aspect of the invention, this problem is solved by a tubular coupler according to claim 7. According to this, the sleeve is surrounded by a molded shell for each section, and this molded shell carries at least one clamping element of the clamping device, and the clamping device clamps the sleeve via the molded shell. Determine.

本発明の両方の態様は、作製された管状連結器が動的負荷の影響を受けにくく、より長い使用寿命を有することが共通している。   Both aspects of the present invention have in common that the fabricated tubular coupler is less susceptible to dynamic loading and has a longer service life.

本発明の第１の形態によれば、スリーブを緊定するための緊定力が、少なくとも１つの緊定バンドを介して導入され、前記緊定バンドまたは各緊定バンドがスリーブを区間ごとに直接取り囲み、本発明に係る緊定バンドの実施形態を条件として、ループ状に曲げられた端部において、動的負荷による亀裂形成の危険が明らかに低減される。   According to the first aspect of the present invention, a tightening force for tightening the sleeve is introduced through at least one tightening band, and the tightening band or each tightening band moves the sleeve into each section. The risk of crack formation due to dynamic loads is clearly reduced at the ends bent directly into the loop and subject to the embodiment of the tightening band according to the invention.

本発明の第２の形態によれば、スリーブの緊定は、緊定ベルトまたは緊定ロープとして実施される、成形筐体に係合する緊定装置の少なくとも１つの緊定要素を介して実施される。スリーブを区間ごとに直接取り囲む成形殻体は、緊定力を生じない。   According to a second aspect of the invention, the tensioning of the sleeve is carried out via at least one tensioning element of the tensioning device which engages the molded housing, which is implemented as a tensioning belt or a tensioning rope. Is done. The molded shell that directly surrounds the sleeve for each section does not generate a tightening force.

本発明の好ましい変形形態は、従属請求項および以下の明細書から明らかである。本発明の例示的な実施形態は、これに限定されるものではないが、図面に則してより詳しく説明する。   Preferred variants of the invention are evident from the dependent claims and the following specification. The exemplary embodiments of the present invention will be described in more detail with reference to the drawings, but are not limited thereto.

図１および２は、図示しない２本の管の隣接する端部を連結するための本発明に係る管状連結器１０の第１の例示的な実施形態を示す。図１および２における例示的な実施形態の管状連結器１０は、互いに連結される管の隣接する端部間のギャップの封止に利用される環状のスリーブ１１を有する。スリーブ１１は、弾性材料から、好ましくはゴム弾性材料から形成される。   1 and 2 show a first exemplary embodiment of a tubular connector 10 according to the present invention for connecting adjacent ends of two tubes (not shown). The tubular coupler 10 of the exemplary embodiment in FIGS. 1 and 2 has an annular sleeve 11 that is utilized to seal the gap between adjacent ends of the tubes that are coupled together. The sleeve 11 is formed from an elastic material, preferably a rubber elastic material.

管状連結器１０のスリーブ１１は、緊定装置を用いて緊定可能であり、図１および２に示す例示的な実施形態において、緊定装置は、２つの緊定バンド１２、１３ならびに４本の緊定ネジ１４によって形成される。緊定バンド１２、１３それぞれは、ほぼスリーブ１１の円周の半分にわたって延び、緊定バンド１２、１３の対向する端部が緊定ネジ１４を介して連結される。緊定バンド１２、１３は、直接スリーブ１１に、すなわち径方向外側にかつ側面で隣接する。それぞれスリーブ１１の円周のほぼ半分にわたって延びる緊定バンド１２、１３双方の代わりに、１つの緊定バンドのみを使用してもよく、その場合この緊定バンドはほぼスリーブ１１の全円周にわたって延び、その場合はこの緊定バンドの対向する端部が好ましくは２本の緊定ネジ１４を介して互いに連結されることを指摘しておく。   The sleeve 11 of the tubular connector 10 can be tightened using a tensioning device, and in the exemplary embodiment shown in FIGS. 1 and 2, the tensioning device comprises two tensioning bands 12, 13 and four. The tightening screw 14 is formed. Each of the tension bands 12, 13 extends approximately half of the circumference of the sleeve 11, and opposite ends of the tension bands 12, 13 are connected via a tension screw 14. The tightening bands 12, 13 are directly adjacent to the sleeve 11, i.e. radially outward and laterally. Instead of both tension bands 12, 13 each extending approximately half the circumference of the sleeve 11, only one tension band may be used, in which case this tension band extends substantially over the entire circumference of the sleeve 11. It is pointed out that the opposite ends of the tensioning band are connected to each other, preferably via two tensioning screws 14.

各緊定バンド１２、１３の各端部１５の領域において、該緊定バンドは、ループ状に曲げられており、緊定バンド１２、１３においてループ状に曲げられた各端部１５は、それぞれ１つの巻回区間１６および連結区間１７を有する。   In the region of each end 15 of each tightening band 12, 13, the tightening band is bent in a loop shape, and each end 15 bent in a loop shape in the tightening bands 12, 13 is respectively One winding section 16 and connection section 17 are provided.

各緊定バンド１２、１３においてループ状に曲げられた各端部１５の巻回区間１６は、ほぼ管状連結器１０の軸方向に延びる緊定ボルト１８を巻回する。緊定バンド１２、１３の緊定ボルト１８と対向する端部１５において緊定ネジ１４が係合し、緊定ネジ１４を締めることによって、管状連結器１０のスリーブ１１を緊定するために、緊定バンド１２、１３において対向する端部１５間の間隔を縮小することができる。   A winding section 16 of each end portion 15 bent in a loop shape in each of the tightening bands 12 and 13 winds a tightening bolt 18 extending substantially in the axial direction of the tubular connector 10. In order to tighten the sleeve 11 of the tubular coupler 10 by engaging the tightening screw 14 at the end 15 of the tightening band 12, 13 facing the tightening bolt 18, and tightening the tightening screw 14. The interval between the end portions 15 facing each other in the tension bands 12 and 13 can be reduced.

緊定バンド１２、１３において対向する端部１５間に延在して緊定バンド１２、１３により覆われていないスリーブ１１の領域は、図示しないカバー要素によって径方向外側が覆われており、このカバー要素を介して緊定バンド１２、１３の端部１５は、緊定ネジ１４を締める際に移動される。図示しないカバー要素は、スリーブ１１がその緊定時に、緊定バンド１２、１３において対向する端部１５間で径方向外側へ逃げることを阻止する。   The region of the sleeve 11 that extends between the opposing ends 15 of the tension bands 12 and 13 and is not covered by the tension bands 12 and 13 is covered radially outside by a cover element (not shown). The end portions 15 of the tension bands 12, 13 are moved through the cover element when tightening the tension screws 14. A cover element (not shown) prevents the sleeve 11 from escaping radially outward between the opposing ends 15 of the tightening bands 12, 13 when tightened.

緊定バンド１２、１３においてループ状に曲げられた各端部１５の連結区間１７の領域においてループ状に曲げられた端部１５は、各緊定バンド１２、１３の外側１９と連結固定されている。   In the region of the connecting section 17 of each end portion 15 bent in a loop shape in the tightening bands 12 and 13, the end portion 15 bent in a loop shape is connected and fixed to the outer side 19 of each tightening band 12 and 13. Yes.

本発明の第１の実施形態によれば、緊定バンド１２、１３においてループ状に曲げられた端部１５それぞれは、端部１５それぞれの巻回区間１６と連結区間１７との間に配置された端部１５それぞれの移行領域２０が、緊定バンド１２、１３それぞれの外側１９に接線方向で接触するように、緊定バンド１２、１３それぞれの外側１９で接線方向に担持される。巻回区間１６は、角度を付けずに各端部１５の連結区間１７へ移行することが好ましい。   According to the first embodiment of the present invention, the end portions 15 bent in a loop shape in the tension bands 12 and 13 are arranged between the winding section 16 and the connection section 17 of each end section 15. The transition region 20 of each end 15 is carried tangentially on the outer side 19 of each of the tension bands 12, 13 such that it contacts the outer side 19 of each of the tension bands 12, 13 in a tangential direction. The winding section 16 preferably transitions to the connecting section 17 of each end 15 without making an angle.

ループ状に曲げられた端部１５それぞれがそれを介して緊定バンド１２、１３それぞれの外側１９と固定連結された緊定バンド１２、１３の端部１５それぞれの連結区間１７は、緊定ボルト１８それぞれから見て、それぞれ曲げられた端部１５の移行領域２０の後方に位置する。それによって、連結区間１７への径方向の力の導入が阻止される。   The connecting sections 17 of the end portions 15 of the tightening bands 12, 13 are connected to the outer sides 19 of the tightening bands 12, 13 via the end portions 15 bent in a loop shape, respectively. 18 is located behind the transition region 20 of each bent end 15 as seen from each. Thereby, the introduction of radial force into the connecting section 17 is prevented.

図１および２の例示的な実施形態において、ループ状に曲げられた端部１５それぞれの連結区間１７は、溶接によってそれぞれ緊定バンド１２、１３の外側１９と固定連結されており、図２に点線で示した溶接継目２１が、ほぼ管状連結器１０の周方向に延在する。その際にループ状に曲げられた端部１５それぞれの連結区間１７は、図２のとおり台形の輪郭の複数の継目板部２２を形成する。台形の輪郭の継目板部２２の縁部２３は、管状連結器１０の周方向と２０°まで、特に１５°までの角度をなす。その結果、縁部２３と隣接する継目板部２２間に形成される楔体は、４０°まで、特に３０°までの開口角度を有することになる。溶接継目２１は、継目板部の縁部２３とほぼ平行に、したがって縁部２３の方向に走る。隣接する継目板部２２間の狭隘部２４は、図２のとおり好ましくは円弧の輪郭となっており、溶接継目２１は、この狭隘部２４中に延在しない。   In the exemplary embodiment of FIGS. 1 and 2, the connecting section 17 of each end 15 bent into a loop is fixedly connected to the outer side 19 of the tension bands 12, 13 by welding, respectively, in FIG. A welded seam 21 indicated by a dotted line extends substantially in the circumferential direction of the tubular coupler 10. At that time, the connecting sections 17 of the end portions 15 bent in a loop form a plurality of joint plate portions 22 having a trapezoidal outline as shown in FIG. The edge 23 of the trapezoidal contoured seam plate part 22 forms an angle with the circumferential direction of the tubular connector 10 up to 20 °, in particular up to 15 °. As a result, the wedge formed between the edge 23 and the adjacent seam plate 22 has an opening angle of up to 40 °, in particular up to 30 °. The weld seam 21 runs substantially parallel to the edge 23 of the seam plate and thus in the direction of the edge 23. As shown in FIG. 2, the narrow portion 24 between the adjacent joint plate portions 22 preferably has an arcuate contour, and the weld seam 21 does not extend into the narrow portion 24.

緊定バンド１２、１３においてループ状に曲げられた端部１５の連結区間１７の上記実施形態により、ならびに連結区間１７の領域で溶接継目２１が上記のように走ることにより、溶接継目２１が実質的に剪断応力にも引張応力にもさらされないことが達成される。さらに、隣接する継目板部２２間の狭隘部２４により、溶接継目２１は、すなわち特に損傷しやすい溶接継目の始端部で負荷が軽減される。   According to the above-described embodiment of the connecting section 17 of the end portion 15 bent in a loop shape in the tension bands 12 and 13, and by the welding seam 21 running as described above in the region of the connecting section 17, the welding seam 21 is substantially In particular, it is achieved that they are not exposed to shear or tensile stresses. Furthermore, the narrow portion 24 between the adjacent seam plate portions 22 reduces the load at the weld seam 21, that is, at the start end portion of the weld seam that is particularly easily damaged.

図３および４は、本発明に係る管状連結器２５のもう１つの例示的な実施形態を示すものであり、図３および４の管状連結器２５は、図１および２の管状連結器１０とは、緊定バンド１２、１３のループ状に曲げられた端部１５の連結区間１７の実施形態によってのみ区別され、したがって、不要な繰返しを避けるために同じ構成要素に対して同じ参照符号が使用される。以下、図３および４の例示的な実施形態が図１および２の例示的な実施形態から区別される細部についてのみ詳述する。   3 and 4 illustrate another exemplary embodiment of a tubular coupler 25 according to the present invention, the tubular coupler 25 of FIGS. 3 and 4 being similar to the tubular coupler 10 of FIGS. Are distinguished only by the embodiment of the connecting section 17 of the looped end 15 of the tightening bands 12, 13, and therefore the same reference numerals are used for the same components to avoid unnecessary repetition Is done. In the following, only the details distinguishing the exemplary embodiment of FIGS. 3 and 4 from the exemplary embodiment of FIGS. 1 and 2 will be described in detail.

図３および４の例示的な実施形態において、緊定バンド１２、１３においてループ状に曲げられた端部１５それぞれの連結区間１７は、それぞれ緊定バンド１２、１３の外側１９と鋲止めによって固定連結されている。つまり図４によれば、連結区間１７は、緊定バンド１２の外側１９と、上下に重なって走る複数の列にまとめられる複数の鋲２６を介して連結されている。連結区間１７をそれぞれの緊定バンド１２、１３の外側１９と鋲止めする際に材料中に熱が取り込まれず、その結果、動的負荷に対する材料の耐性が高くなり、亀裂形成の危険が溶接接合に比べて低減される。したがって図３および４の例示的な実施形態においても、スリーブ１１を緊定するための緊定力は、スリーブ１１に直接隣接する緊定バンド１２、１３を介して導入される。   In the exemplary embodiment of FIGS. 3 and 4, the connecting section 17 of each end 15 that is bent in a loop in the tension bands 12, 13 is secured to the outer side 19 of the tension bands 12, 13, respectively, by a clasp. It is connected. That is, according to FIG. 4, the connecting section 17 is connected to the outer side 19 of the tension band 12 via a plurality of rods 26 that are combined into a plurality of rows that run vertically. When the connection section 17 is clamped to the outer side 19 of the respective tightening bands 12 and 13, heat is not taken into the material, so that the material is more resistant to dynamic loads and the risk of crack formation is welded. Compared to Therefore, also in the exemplary embodiment of FIGS. 3 and 4, the tightening force for tightening the sleeve 11 is introduced via the tightening bands 12, 13 directly adjacent to the sleeve 11.

図５および６は、本発明の第２の実施形態による本発明に係る管状連結器２７の例示的な実施形態を示すものであり、この管状連結器２７は、やはり２本の管の隣接する端部の連結に利用され、管状連結器２７のスリーブが、互いに連結される管の隣接する端部間のギャップを封止する。このスリーブは、やはり弾性材料、好ましくはゴム弾性材料から形成される。スリーブは、図５、６には示されておらず、スリーブがその緊定の際に径方向外側に逃げることを阻止するカバー要素２８が示されている。   FIGS. 5 and 6 show an exemplary embodiment of a tubular connector 27 according to the invention according to a second embodiment of the invention, which is also adjacent to two tubes. Used to connect the ends, the sleeve of the tubular connector 27 seals the gap between adjacent ends of the tubes that are connected together. This sleeve is again formed from an elastic material, preferably a rubber elastic material. The sleeve is not shown in FIGS. 5 and 6 and a cover element 28 is shown which prevents the sleeve from escaping radially outward during its tightening.

緊定されるスリーブは、図５および６のとおり、成形筐体２９によって区間ごとに取り囲まれており、緊定装置の緊定要素３０が成形筐体２９で径方向外側に担持される。緊定要素３０は、図５および６のとおり、緊定ベルトとして形成されており、緊定ベルト３０の端部３１は、それぞれ１つの緊定ボルト３２を取り囲むループを形成する。緊定ボルト３２は、ほぼ管状連結器２７の軸方向に延びる。緊定ボルト３２には、ほぼ管状連結器２７の周方向に延びる緊定ネジ３３が係合する。   As shown in FIGS. 5 and 6, the sleeve to be tightened is surrounded by the molded housing 29 for each section, and the tightening element 30 of the tightening device is carried radially outward by the molded housing 29. The tensioning element 30 is formed as a tensioning belt as shown in FIGS. 5 and 6, and the end 31 of the tensioning belt 30 forms a loop that surrounds one tensioning bolt 32. The tightening bolt 32 extends substantially in the axial direction of the tubular connector 27. A tightening screw 33 extending substantially in the circumferential direction of the tubular coupler 27 is engaged with the tightening bolt 32.

緊定ベルト３０は、好ましくはポリマー化合物、特にポリエステルから形成される。このようなポリマー化合物の高い破壊伸びによって、緊定ベルト３０は動的負荷の影響を受けにくくなる。緊定ベルト３０は、スリーブの緊定に利用されるすべての周方向の力を吸収し、その結果、スリーブに直接隣接する管状連結器２７の成形筐体２９が緊定力を受け止める必要がない。   The tensioning belt 30 is preferably formed from a polymer compound, in particular polyester. Due to the high breaking elongation of such a polymer compound, the tension belt 30 becomes less susceptible to dynamic loads. The tensioning belt 30 absorbs all circumferential forces used for the tensioning of the sleeve, so that the molded housing 29 of the tubular connector 27 immediately adjacent to the sleeve does not have to accept the tensioning force. .

図７および８は、本発明の第２の実施形態における本発明に係る管状連結器３４の第２の例示的な実施形態を示すものであり、この図７および８の例示的な実施形態は、緊定装置の緊定要素として緊定ベルトの代わりに２本の緊定ロープ３５が使用されることによってのみ、図５および６の例示的な実施形態から区別される。その他の細部については図７および８の例示的な実施形態は図５および６の例示的な実施形態と一致し、したがって不要な繰返しを避けるために同じ構成要素に対して同じ参照符号が使用されている。   FIGS. 7 and 8 show a second exemplary embodiment of a tubular coupler 34 according to the present invention in a second embodiment of the present invention, the exemplary embodiment of FIGS. A distinction is made from the exemplary embodiment of FIGS. 5 and 6 only by the use of two tensioning ropes 35 instead of tensioning belts as tensioning elements of the tensioning device. For other details, the exemplary embodiment of FIGS. 7 and 8 is consistent with the exemplary embodiment of FIGS. 5 and 6, and therefore the same reference numerals are used for the same components to avoid unnecessary repetition. ing.

図７および８の例示的な実施形態においても、スリーブ２８の緊定のために必要になる周方向の力は緊定ロープ３５によって完全に吸収され、その結果、成形筐体２９は緊定力を伝達または吸収する必要がない。緊定ロープ３５は、好ましくは鋼ロープとして形成される。   Also in the exemplary embodiment of FIGS. 7 and 8, the circumferential force required for tightening of the sleeve 28 is completely absorbed by the tightening rope 35 so that the molded housing 29 is tightened. There is no need to transmit or absorb. The tensioning rope 35 is preferably formed as a steel rope.

図７および８による緊定ロープを使用する場合、機械的損傷に対する抵抗力は、図５および６記載の緊定ベルトを使用する場合よりも多少良好であるが、製造費用は緊定ロープを使用する場合よりも高くなる。緊定ベルトを使用する場合の方が、緊定ロープを使用する場合よりも、緊定ボルト３２を介した力の導入が良好である。   When using the tensioning rope according to FIGS. 7 and 8, the resistance to mechanical damage is somewhat better than when using the tensioning belts according to FIGS. 5 and 6, but the production costs use the tensioning rope. Higher than if you want to. When the tension belt is used, the introduction of force through the tension bolt 32 is better than when the tension rope is used.
