Description

本発明は、少なくとも１つの光線源を有し、光硬化性材料から成る更生すべきライニング内を走行する硬化更生装置に関する。   The present invention relates to a curing and rehabilitation device having at least one light source and traveling in a lining to be rehabilitated made of a photocurable material.

紫外線源を備えた上記のような硬化装置は例えば特許文献１に開示されている。
好ましくない、破損した配管は、硬化性の成形剤（修復剤）により現場で新しい配管を形成する、いわゆる更生工法により修理される。この際、硬化性の合成樹脂を浸透させたライニングを修理すべき破損した配管内へと挿入して配置し、その位置でこのライニングが硬化される。尚、硬化性の合成樹脂としては通常紫外線硬化性樹脂が使用される。
即ち、ライニングを圧縮空気により破損した配管の内壁に圧着した後、紫外線ランプを備えた台車が一定の速度でライニング内を走行する。このとき、紫外線硬化樹脂をライニング周囲で均等に硬化させるために、紫外線ランプをライニング或いは配管の軸中心線上に位置させなければならない。 For example, Patent Document 1 discloses a curing apparatus having an ultraviolet ray source as described above.
Unwanted damaged pipes are repaired by a so-called rehabilitation method in which new pipes are formed in the field with a curable molding agent (restoring agent). At this time, a lining infiltrated with a curable synthetic resin is inserted into a damaged pipe to be repaired and disposed, and the lining is cured at that position. As the curable synthetic resin, an ultraviolet curable resin is usually used.
That is, after the lining is crimped to the inner wall of the pipe damaged by the compressed air, a carriage equipped with an ultraviolet lamp travels in the lining at a constant speed. At this time, in order to cure the ultraviolet curable resin evenly around the lining, the ultraviolet lamp must be positioned on the axial center line of the lining or piping.

独国特許出願公開第１０２００４０２９６３１号明細書German Patent Application No. 102004029631

従来、紫外線ランプとしてガス放電ランプが使用されている。しかしながら、ガス放電ランプは大きな赤外線領域を有するため多くの熱が発生するとともに、寿命がたったの約１０００時間である上、かなりのウォーミングアップ時間を要するという問題があった。   Conventionally, gas discharge lamps are used as ultraviolet lamps. However, since the gas discharge lamp has a large infrared region, it generates a lot of heat and has a problem that it has a lifetime of only about 1000 hours and requires a considerable warm-up time.

又、ガス放電ランプのランプ長さにより台車がその内部を走行可能な配管の曲率半径が制限されてしまうという問題もあった。   There is also a problem that the radius of curvature of the pipe through which the carriage can travel is limited by the length of the gas discharge lamp.

更に、複数のガス放電ランプを用いる際には、それらを接続するケーブルにより影が生じ、配管内で紫外線をムラなく照射し難いため、成形剤（修復剤）を均等に硬化させることが難しいという問題もあった。   Furthermore, when using a plurality of gas discharge lamps, it is difficult to uniformly cure the molding agent (restoration agent) because shadows are generated by the cables connecting them, and it is difficult to irradiate ultraviolet rays uniformly in the piping. There was also a problem.

本発明は上記問題に鑑みてなされたもので、その目的とする処は、上記問題を解消する硬化更生装置を提供することにある。   The present invention has been made in view of the above problems, and its object is to provide a curing / rehabilitation apparatus that solves the above problems.

上記目的は、本発明によれば、光線源を硬化更生装置の外周面に配設した複数のＬＥＤで構成したことにより解決される。   According to the present invention, the above object is solved by configuring the light source with a plurality of LEDs arranged on the outer peripheral surface of the curing / rehabilitation apparatus.

特に、ＬＥＤが約３００ｎｍ〜約５００ｎｍの波長の光を放射することが好ましく、更生すべきライニングが紫外線硬化性材料から成る場合にはＬＥＤが紫外線を放射し、更生すべきライニングが可視光硬化性材料から成る場合にはＬＥＤが可視光を放射する。   In particular, it is preferable that the LED emits light having a wavelength of about 300 nm to about 500 nm. When the lining to be renewed is made of an ultraviolet curable material, the LED emits ultraviolet light, and the lining to be renewed is visible light curable. When made of material, the LED emits visible light.

本発明によれば、例えば波長が３６５ｎｍ又は４０５ｎｍ（±１０ｎｍ）の照度の強い紫外線ＬＥＤが使用される。紫外線ＬＥＤは赤外線を全く放射しないため、熱の発生が抑制され、熱の影響を受け易い材料にも照射することができる。   According to the present invention, for example, an ultraviolet LED having a high illuminance with a wavelength of 365 nm or 405 nm (± 10 nm) is used. Since the ultraviolet LED does not emit infrared rays at all, the generation of heat is suppressed, and it is possible to irradiate materials that are easily affected by heat.

又、紫外線ＬＥＤのほぼ単色性のスペクトルは、紫外線硬化樹脂の感光開始に調和するため、確実且つ迅速な硬化に最適である。そして、ＬＥＤはウォーミングアップ時間が不要であり、硬化更生装置のＯＮ／ＯＦＦを問題なく行うことができ、直ちに使用することができる。   In addition, the almost monochromatic spectrum of the ultraviolet LED is in harmony with the initiation of photosensitivity of the ultraviolet curable resin, and is optimal for reliable and rapid curing. The LED does not require a warm-up time, can turn on / off the curing / rehabilitation apparatus without any problem, and can be used immediately.

そして、ＬＥＤの寿命は約３００００時間にも達し、故障したＬＥＤがある場合にも適切に交換することができる。更に、ＬＥＤは点光源であるため、配管の曲率半径の影響を受けることもない。   The life of the LED reaches about 30000 hours, and can be appropriately replaced even when there is a failed LED. Furthermore, since the LED is a point light source, it is not affected by the radius of curvature of the piping.

而して、ＬＥＤは、できる限り均等な照射を行うために、硬化更生装置の長手方向軸中心線を中心として均等に配設されている。又、ＬＥＤは、少なくとも１つのホルダ、及び台車の支持部材に設けられており、ホルダを球状に形成すれば、更生すべきライニングの湾曲した内壁に均等に照射することができるため好ましい。   Thus, the LEDs are evenly arranged around the longitudinal axis center line of the curing / rehabilitation apparatus in order to perform irradiation as evenly as possible. Further, the LED is provided on at least one holder and a support member of the carriage, and if the holder is formed in a spherical shape, it is preferable that the curved inner wall of the lining to be rehabilitated can be evenly irradiated.

他の利点及び有利な実施の形態は、明細書、図面及び特許請求の範囲に記載されている。本発明の適用は、上記の説明及び下記の実施の形態に制限されるものではなく、本発明の範囲を逸脱しない範囲内で適宜組み合わせて用いることができる。   Other advantages and advantageous embodiments are described in the description, the drawings and the claims. The application of the present invention is not limited to the above description and the following embodiments, and can be used in appropriate combinations within a range not departing from the scope of the present invention.

以下に本発明の実施の形態を添付図面に基づいて説明する。   Embodiments of the present invention will be described below with reference to the accompanying drawings.

図１に示す硬化更生装置１は、紫外線硬化性樹脂を塗布されて配管２に内張りされたライニング３を紫外線によって硬化させるものであり、配管２内を走行できるよう台車支持部材５を有する台車４及び前記台車支持部材５に弾性支持されたローラ６を備えている。   A curing / rehabilitation apparatus 1 shown in FIG. 1 cures a lining 3 coated with an ultraviolet curable resin and lined on a pipe 2 with ultraviolet rays, and has a carriage 4 having a carriage support member 5 so that it can travel in the pipe 2. And a roller 6 elastically supported by the cart support member 5.

ここで、ローラ６を台車４の長手方向軸中心線７に関して互いに対向して設け、台車４を配管２内の中心位置を維持して走行せしめることができる。   Here, the rollers 6 can be provided opposite to each other with respect to the longitudinal axis center line 7 of the carriage 4 so that the carriage 4 can run while maintaining the center position in the pipe 2.

又、台車支持部材５の両端部には球状の紫外線ＬＥＤホルダ８が設けられており、この紫外線ＬＥＤホルダ８表面には紫外線ＬＥＤ９がほぼ均等に配設されている。そして、台車４は、紫外線ＬＥＤホルダ８（図中左側）に取り付けられたケーブル１０により配管２内を符号１１で示す方向に走行する。一方、他方の紫外線ＬＥＤホルダ８（図中右側）には紫外線ＬＥＤ９に電力を供給するための電源ケーブル１２が接続されている。   Further, spherical ultraviolet LED holders 8 are provided at both ends of the carriage support member 5, and the ultraviolet LEDs 9 are arranged almost uniformly on the surface of the ultraviolet LED holder 8. The carriage 4 travels in the direction indicated by reference numeral 11 in the pipe 2 by the cable 10 attached to the ultraviolet LED holder 8 (left side in the figure). On the other hand, a power cable 12 for supplying power to the ultraviolet LED 9 is connected to the other ultraviolet LED holder 8 (right side in the figure).
