Description

本発明は、光硬化性樹脂を含浸させたライニング材を利用し、既設配管の内面をライニングする配管補修装置に関する。 TECHNICAL FIELD The present invention relates to a pipe repairing device that uses a lining material impregnated with a photocurable resin to line the inner surface of an existing pipe.

下記特許文献１に記載のライニング方法およびライニング装置が知られていた。
これは、未硬化状態の光硬化性樹脂を含浸させた管状ライニング材を既設配管の内面に導入し、加圧気体によりその外周を配管に密着させた状態で、ライニング材の内面から光照射装置により光照射して、ライニング材を硬化することが行われている。
この光硬化ライニング法で使用されるライニング材は、一般的にガラス繊維の編込み物に光硬化性の樹脂（例えば、ビニルエステル樹脂、不飽和ポリエステル樹脂、エポキシ樹脂等）を含浸させたものが使用される。
そして、紫外線ランプからなる光照射装置には放射方向に車輪が設けられており、ライニング材の内側の中心部にランプ本体が保持されて移動できるようになっている。この場合、紫外線ランプは配管の上流側から下流側に移動速度を１５～２０ｃｍ／ｍｉｎで移動していた。その照射光の波長は、３６５～４００ｎｍであり、その光の波長に適合するように光硬化性樹脂の光反応開始材を調整するものであった。 A lining method and a lining apparatus described in Patent Document 1 below have been known.
In this method, a tubular lining material impregnated with an uncured photocurable resin is introduced into the inner surface of an existing pipe, and a light irradiation device is applied from the inner surface of the lining material while the outer periphery of the lining material is brought into close contact with the pipe by pressurized gas. The lining material is cured by irradiating with light.
The lining material used in this photocurable lining method is generally a woven glass fiber impregnated with a photocurable resin (for example, vinyl ester resin, unsaturated polyester resin, epoxy resin, etc.). used.
The light irradiation device composed of the ultraviolet lamp is provided with wheels in the radial direction, and the lamp body is held in the central part inside the lining material so that the lamp body can be moved. In this case, the ultraviolet lamp moved from the upstream side of the pipe to the downstream side at a moving speed of 15 to 20 cm/min. The wavelength of the irradiation light was 365 to 400 nm, and the photoreaction initiator of the photocurable resin was adjusted so as to match the wavelength of the light.

紫外線ランプを複数連結し、ライニング材を硬化させる場合、電力消費が極めて大きいと共に、その移動速度が遅い欠点がある。
また、紫外線ＬＥＤによってライニングする場合には、その発光量が電力の８０％を占め、発熱量は２０％である。
また、近年効率のよいＬＥＤが生産されるようになり、その連結個数を増加してライニング作業を効率よく行う試みが多くなってきている。
しかしながら、既設配管の直径は各種、多数存在し、その配管直径毎に光照射装置を製作することは極めて面倒である。
そこで、本発明は一例として、配管直径が２５０～６００ｍｍの各種既設配管まで多用できる配管補修装置を提供することを目的とする。 When a plurality of UV lamps are connected to cure the lining material, there are drawbacks such as extremely high power consumption and slow moving speed.
In the case of lining with ultraviolet LEDs, the amount of light emitted accounts for 80% of the electric power, and the amount of heat generated is 20%.

各リンク機構５は、第１リンク５ａと第２リンク５ｂとからなる。この例では、第１リンク５ａ，第２リンク５ｂはその中央部がＸ字状に軸支され且つ、その第１リンク５ａの一端側が駆動体（アウタロータ）４に突設された第１支持リング１３に軸支される。それと共に、第２リンク５ｂの一端側が、第２支持リング１４に軸支されている。その第２支持リング１４は中心軸１０の軸方向に移動自在に被嵌されている。また、第１リンク５ａと第２リンク５ｂの他端が、光照射装置６の基部６ａに軸支され、その基部６ａに多数のＵＶ－ＬＥＤ６ｂが分散配置されている。リンク機構５は、その外周直径を任意位置に維持するための、図示しない保持機構を有する。 The central member 1 has a camera 12 at the center of its tip, and front lighting 8 by a large number of LEDs is arranged radially from the position of the camera 12 . A plurality of legs 2 are radially arranged on the central member 1 in the radial direction of the central axis 10 and can be expanded or contracted. An inner block (stator) is provided inside the motor casing 3, and a driving body 4 as an outer rotor is fitted around the outer periphery thereof. In this example, four link mechanisms 5 are radially arranged on the driving body (outer rotor) 4 .
Each link mechanism 5 consists of a first link 5a and a second link 5b. In this example, the first link 5a and the second link 5b are axially supported in an X shape at their central portions, and one end side of the first link 5a protrudes from the driving body (outer rotor) 4 as a first support ring. 13. At the same time, one end side of the second link 5b is pivotally supported by the second support ring 14. As shown in FIG. The second support ring 14 is fitted so as to be movable in the axial direction of the central shaft 10 . The other ends of the first link 5a and the second link 5b are pivotally supported by the base 6a of the light irradiation device 6, and a large number of UV-LEDs 6b are dispersedly arranged on the base 6a. The link mechanism 5 has a holding mechanism (not shown) for maintaining its outer diameter at an arbitrary position.

この光照射装置６の基部６ａの表面は、リンク機構５により、常に中心軸１０の軸線に平行に維持されている。
次に、この例では、４つの脚体２の一端が中心部材１に固定され、その脚体２は基部２ａとその基部２ａの根元に屈曲自在に配置された屈曲部２ｂとを有し、その屈曲部２ｂの先端に車輪２ｃが設けられている。中心部材１と一体の中心軸１０の後端には、コネクタ９が設けられ、そのコネクタ９を介して複数の配管補修装置が軸線方向に直列に、図２に示す如く連結される。 The surface of the base portion 6 a of the light irradiation device 6 is always maintained parallel to the axis of the central shaft 10 by the link mechanism 5 .

A connector 9 is provided at the rear end of the central shaft 10 integral with the central member 1, and a plurality of pipe repairing devices are connected in series in the axial direction via the connector 9, as shown in FIG.

〔作用〕
先ず、図２に示す如く、複数の配管補修装置が中心軸１０の軸線方向にコネクタ９を介して連結される。そして、モータケーシング３にこの例では電源が供給され、駆動体（アウタロータ）４を回転駆動する。
なお、駆動体（アウタロータ）４の回転は周方向に連続的に回転してもよいが、それに変えて軸線の周りに間欠的に反転を繰り返すものであってもよい。
中心軸１０の内部には、図示しないケーブルが挿通され、駆動体（アウタロータ）４の駆動源を形成する。なお、駆動源は電源に限らず、空気圧源を用いてもよい。
そして、既設配管１１の内面にライニング材７が被覆され、空気圧によりそれが既設配管１１の内面に密着する。この状態で、本装置の中心部材１の先端が既設配管１１内を、適宜速度で下流側に移動する。 [Action]
First, as shown in FIG. 2, a plurality of pipe repair devices are connected via connectors 9 in the axial direction of the central shaft 10 . In this example, power is supplied to the motor casing 3 to rotate the driving body (outer rotor) 4 .
The driving body (outer rotor) 4 may be rotated continuously in the circumferential direction, but alternatively, the rotation may be intermittently repeated around the axis.
A cable (not shown) is inserted through the center shaft 10 to form a drive source for the driving body (outer rotor) 4 . Note that the drive source is not limited to the power source, and an air pressure source may be used.
The inner surface of the existing pipe 11 is covered with the lining material 7, and the lining material 7 adheres to the inner surface of the existing pipe 11 by air pressure. In this state, the tip of the central member 1 of this device moves downstream at an appropriate speed in the existing pipe 11 .

このとき、各脚体２の長さ及び、ライニング材７の内面と光照射装置６との距離が一定に保たれる。
光照射装置６は、その背面側（リンク機構５側）に多数の冷却フィン１５（図５参照）が配置され、駆動体（アウタロータ）４の回転に伴い、基部６ａおよびＵＶ－ＬＥＤ６ｂを冷却する。駆動体（アウタロータ）４の回転速度は、一例として、１００ｒｐｍあれば、十分に冷却効果を発揮する。
既設配管１１の内直径が最小のものに対しては図３（Ａ）に示す如く、脚体２の屈曲部２ｂがＬ字状に屈曲して、車輪２ｃが既設配管１１の内面側に接触する。既設配管１１の内直径が中間の場合は、図３（Ｂ）の如く、屈曲部２ｂが基部２ａに対してヘの字状に曲折し、その車輪２ｃが既設配管１１内面に図示しないライニング材を介して接触する。また、既設配管１１が最大直径の場合には、図３（Ｃ）に示す如く、基部２ａの最延長上に屈曲部２ｂが直線的に伸びる。この例では、屈曲部２ｂはその一端が捩じりコイル状に形成されているが、それに変えて基部２ａ内に、シリンダのように直線的に伸縮自在に収納されるものであってもよい。
同様に、光照射装置６の位置もリンク機構５を介して、所定の半径に維持される。即ち、光照射装置６の外周半径が、リンク機構５により、既設配管１１の内周半径に合わせて、伸縮配置され、光照射装置６とライニング材７との距離が所定距離に維持される。これにより、ライニング材７の光硬化を効率的に行う。 At this time, the length of each leg 2 and the distance between the inner surface of the lining material 7 and the light irradiation device 6 are kept constant.
The light irradiation device 6 has a large number of cooling fins 15 (see FIG. 5) on its back side (link mechanism 5 side), and cools the base 6a and the UV-LED 6b as the driving body (outer rotor) 4 rotates. . If the rotation speed of the driving body (outer rotor) 4 is 100 rpm, for example, a sufficient cooling effect can be obtained.
When the inner diameter of the existing pipe 11 is the smallest, the bent portion 2b of the leg 2 is bent in an L shape as shown in FIG. do. When the inner diameter of the existing pipe 11 is intermediate, as shown in FIG. contact through. Also, when the existing pipe 11 has the maximum diameter, as shown in FIG. In this example, one end of the bent portion 2b is formed in a twisted coil shape, but instead, it may be housed in the base portion 2a so as to be linearly extendable and retractable like a cylinder. .
Similarly, the position of the light irradiation device 6 is also maintained at a predetermined radius via the link mechanism 5 . That is, the outer circumference radius of the light irradiation device 6 is expanded and contracted according to the inner circumference radius of the existing pipe 11 by the link mechanism 5, and the distance between the light irradiation device 6 and the lining material 7 is maintained at a predetermined distance. As a result, the lining material 7 is efficiently photo-cured.

また、コネクタ９に介して、直線上に連結された複数の配管補修装置は、最先端の装置の中心部材１に固定された図示しないワイヤにより、図２の矢印方向に所定の定速度で移動する。このとき、各光照射装置６は、駆動体（アウタロータ）４の回転に伴い中心軸１０の周りをゆっくり回動する。それにより、中心軸１０に被覆されたライニング材７の内面を多数のＵＶ－ＬＥＤ６ｂを有する光照射装置６の光が照射し、ライニング材７を硬化させる。このとき、進行方向の上流側の駆動体（アウタロータ）４の回転と、それに隣接する下流側の駆動体（アウタロータ）４の回転とは逆向きになる。その状態を図２において矢印で示す。
それに伴って、光照射装置６は実線の状態から想像線の状態に回動する。それらの回転速度、移動速度は、任意に選択することができる。そして、ライニング材７の内面を中心部材１に設けられたカメラ１２により観察する。カメラ１２は下流側の装置にも設けることができる。また、下流側の装置の後端にも前照明８を配置することが好ましい。 A plurality of pipe repairing devices connected in a straight line via a connector 9 are moved at a predetermined constant speed in the direction of the arrow in FIG. do. At this time, each light irradiation device 6 rotates slowly around the central axis 10 as the driving body (outer rotor) 4 rotates. As a result, the inner surface of the lining material 7 coated on the central shaft 10 is irradiated with light from the light irradiation device 6 having a large number of UV-LEDs 6b, and the lining material 7 is cured. At this time, the rotation of the driving body (outer rotor) 4 on the upstream side in the direction of travel and the rotation of the driving body (outer rotor) 4 on the downstream side adjacent thereto are opposite to each other. This state is indicated by an arrow in FIG.
Accordingly, the light irradiation device 6 rotates from the solid line state to the imaginary line state. Their rotation speed and movement speed can be arbitrarily selected. Then, the inner surface of the lining material 7 is observed by the camera 12 provided on the central member 1 . Camera 12 may also be provided in downstream equipment. Further, it is preferable to arrange the front lighting 8 also at the rear end of the device on the downstream side.

次に、図４は、本配管補修装置を直列に多数連結した状態を示し、進行方向の奇数番目の駆動体（アウタロータ）４の回転と、偶数番目の駆動体（アウタロータ）４の回転とは逆向きになる。 Next, FIG. 4 shows a state in which a number of pipe repair devices are connected in series, and the rotation of the odd-numbered driving bodies (outer rotors) 4 in the traveling direction and the rotation of the even-numbered driving bodies (outer rotors) 4 are different. going backwards.

本発明の実施例では、光照射装置を駆動体（アウタロータ）４により回転させたが、駆動体（アウタロータ）４の回転を停止した状態で、本装置を既設配管１１内に移動させてもよい。請求項１に記載の発明は、駆動体（アウタロータ）４の回転を停止した場合も含み、その効果を明細書の詳細な説明に記載する。
また、駆動体（アウタロータ）４の駆動方法は、各種公知の技術を利用できる。 In the embodiment of the present invention, the light irradiation device is rotated by the driver (outer rotor) 4, but the device may be moved into the existing pipe 11 with the rotation of the driver (outer rotor) 4 stopped. . The invention described in claim 1 includes the case where the rotation of the driving body (outer rotor) 4 is stopped, and the effect thereof will be described in the detailed description of the specification.
Further, various known techniques can be used for the driving method of the driving body (outer rotor) 4 .
