Description

The invention relates to a radiation source with lamps for irradiation of the interior walls of elongated cavities with continuous movement of the radiation along the axis of the cavity, especially radiation-hardening for curing Resins for the interior renovation of pipes and sewers station lines using UV radiation, with a chassis, on the circumference of which several lamps are arranged.  

Such radiation sources, especially if they are with UV lamps are used in the interior renovation of pipe and Sewerage lines required. This interior renovation ge is created by the fact that a multilayer, tubular structure, at least one layer with a radiation curable Resin is soaked in the pipe section to be renovated drawn in and flat in it by the pressure of a fluid is pressed against the pipe or sewer line. By the passage of the radiation source becomes that on the world Len length of the radiation source hardened resin. This process assumes that the resin in question is from the high-energy radiation is applied for what purpose either the resin-impregnated tube layer immediately the Radiation source is turned, or the resin-impregnated Layer of tubing introduced at the same time or subsequently Has inner film that for the radiation in question is casual.

Of particular importance here is economy considerations of movement speed or driving speed radiation source, and this in turn depends on the radiation intensity of the lamps in relation to each Area element of the inner wall to be irradiated. Under "Inside wall "means the surface that closes Lich the renewed inner wall of the pipe or sewerage tion forms, so the inner surface of the retracted and opened blown hose.  

By US-PS 41 35 958 is a radiation source known genus known in the case of the scope of a screen designed as a rotating body a plurality is arranged by lamps that either visible light or Send out infrared radiation to harden the resin. The be Known solution is only suitable for a narrow through area of the pipeline to be rehabilitated, since with increasing distance of the lamps from the surface to be irradiated not only the radiation intensity, but also the Shielding effect decreases. One would have to go for the lot number of possible line diameters is a corresponding one Provide variety of radiation sources, which the renovation is significantly more expensive.

The invention is therefore based on the object of a beam Specification source of the genus described above, the easily on different piping to be renovated diameter can be converted and easy to set up and is reliable in effect. In particular, despite this spatially limited radiation of the individual lamps is possible as uniform as possible irradiation of the interior to be treated walls can be reached.

The task is solved at the beginning specified radiation source according to the invention in that

• a) the chassis one running in the axial direction has central support on which each of the lamps with is attached to an outward-facing reflector,  
• b) a first group of lamps in a first axial area of the carrier at least essentially equidistantly distributed over the circumference of the carrier is arranged and
• c) at least one further group of the same size of the lamps in at least one subsequent axial one Area of the carrier in the circumferential direction around a part of the Angular distance of the lamps of the first group offset likewise at least essentially equidistant on the Scope of the carrier is arranged distributed.

By using a central beam, it is possible on the outside there are lamps with reflectors Lichen radial distances to be arranged from the carrier, at the same time but in an optimal and the same for all applications distance from the inner surface to be irradiated.

This possibility of variation enforces a certain minimum knife ahead of a circle on which the longitudinal axes of the Lamps are arranged, the same in the circumferential direction corresponding distance of the lamps and reflectors in the Dimensions becomes larger, like the individual lamps when used in larger cable diameters in the radial direction to the outside must be relocated. This in turn creates between the individual lamps so-called "dark rooms", in which advantageous in a manner to be described below hold the support rollers. For comparison moderation of the radiation intensity to the total extent of the The lamps of the second group are therefore in the inside wall Circumferential direction by part of the angular distance between the lamps offset from the first group and also equidistant  distributed on the circumference of the carrier. Especially the individual lamps of the second are advantageously Group arranged in the bisecting planes that between the lamps of the first group. With corresponding The arrangement of the lamps and the dimensioning of the reflectors this allows an extremely uniform beam achieve intensity, which leads to a very even out leads to hardening of the resin.

Such resins are confectioned with appropriate activators available in stores, tailored to each because of the wavelength or the wavelength spectrum of the individual lamps. Also about materials for the individual layers of the renovation hose can be found with regard to the Radiation permeability (inner film, fiber layer) or - impermeability (outer film) references in the literature.

Due to the offset of the individual lamp groups in the circumferential direction tion (the arrangement of the lamps of the second group in the Halving the lamps of the first group is at Presence of two groups of lamps) one is used extremely uniform distribution of high-energy radiation on the entire circumference of the inner wall to be irradiated, at least at the moment when they are in driving lane rearmost lamp group a certain axial point of the Pipeline has passed.

It is particularly advantageous if in the Winkelhal between the lamps and reflectors of each Group attached to the carrier radially aligned support rollers are.  

Here, lamps and support rollers alternate on the circumference from, in each case also according to the lamps offset circumferentially, making an excellent Stability of the chassis is achieved, even then, if the radiation source via lateral pipe openings or Branches is moved, creating a single support roller Losing grip loses. A radiation source with three lamps in each of the two axial areas thus moves to a total six lanes ver. ver on the inner wall of the pipeline are divided. The associated load distribution also brings considerable advantages in terms of the deformation of the beginning still plastic resin with itself. It will also a short overall length of the entire radiation source enables which in turn makes the handling of the radiation source easier tert.

It is also advantageous if the lamps with the Reflectors as assemblies with radial connectors are connected to the carrier.

Differentiated to adapt the radiation source to pipes Liche inner diameter or cross-sectional shape can construction groups with connecting pieces of different lengths between the plug connections and the lamps and reflectors ready are held so that when the chassis is used in a pipe with a different diameter only it is necessary to replace the relevant modules, and replace the support rollers in a corresponding manner, to adjust or with the interposition of distance elements to be attached to the carrier again.  

A particularly powerful radiation source is then ge give if the reflectors as thin-walled approximately square Cutouts from cylindrical shells with an edge length between 80 and 100 mm and a radius of curvature between 80 and 96 mm are formed and if the smallest distance between the lamp axis

• a) from the reflector between 15 and 25 mm and
• b) of the wall surface to be irradiated between 60 and 80 mm is.

The values found during optimization attempts are exactly in the middle of the specified ranges for edge length, curvature radius and distances of the lamp axis.

UV processing has proven to be particularly advantageous in processing. Radiation-curable resins have proven to be particularly useful is partial if the lamps have UV lamps arranged parallel to the axis Quartz lamps are. The correspondingly curved and arranged For example, reflectors can be made of metal but particularly advantageous from a correspondingly curved mineral substrate formed on the side of the lamps has a UV reflective coating. It is about this is a so-called "cold light mirror", which is the infrared radiation from the surface to be irradiated very largely keep away so that no noticeable thermal damage to the individual layers of tubing occurs, and not even if, contrary to expectations, the radiation source is temporarily switched on will hold.  

It is also particularly advantageous if the UV quartz lamps are surrounded by an additional quartz bulb, the protects the quartz lamps against environmental influences, in particular against air movement due to unavoidable leakage on the one hand and the movement of the chassis on the other on the one hand occurs during operation.

The carrier is a very special advantage as a regular polygonal hollow profile formed, the longitudinal edges tough lenlich twice the number in an axial range ordered lamps corresponds, whereby on the flat Seitenflä Chen the hollow profile on the circumference alternately plug-in for the lamps and pedestals for the support rollers are ordered.

For irradiating the inner walls of pipelines at the bottom At the end of the possible diameter scale, a carrier is appropriate used, which is formed from a hollow hexagonal profile. With increasing pipeline diameter one becomes a carrier with use a larger number of longitudinal edges, for example Hollow profiles with ten longitudinal edges, so that in an axial loading each has five lamps with reflectors and five support rollers are arranged alternately on the circumference. The term "pipe lines "is not to be those with a circular cross-section borders. Rather, the subject of the invention can also be in channel cross sections with egg shape, mouth shape or other of the circle deviating cross-sections are used. The poss Different center distances of lamps and supports roll lets the adaptation of the radiation source to almost be any channel or pipe cross sections.  

Further advantageous refinements of the subject matter of the invention that are contained in the remaining subclaims.

Two exemplary embodiments of the subject matter of the invention and their possible variations are explained in more detail below with reference to FIGS. 1 to 9.

Fig. 9 is a radial section analogous to Fig. 1 with a larger number of lamps, reflectors and support rollers for a larger diameter range of the pipeline to be renovated.

In Figs. 1 and 2 there is shown a pipeline to be rehabilitated 1, which consists of a laid in the ground concrete pipe, but may be available from other known tube materials such as, cast iron, plastic, etc. was made of brickwork in this pipeline already renovation hose 2 a drawn, which is constructed in a manner not shown here from several layers, of which at least one layer consists of a nonwoven fabric and / or fabric that is impregnated with a resin that can be cured by the addition of certain activators by UV radiation and forms a solid tube after hardening. The conditions for such hardening are described in the literature and therefore do not need to be explained in more detail here.

The curing is done by a radiation source 3 , which is pulled through this in the axial direction of the pipeline 1 continuously, ie at a constant speed, so that the originally still largely flowable or plastic resin forms a solid tube after passing through the radiation source with the remaining hose material.

The radiation source 3 includes a chassis 4 , the core piece is an axially extending central carrier 5 , which is formed by a regular polygonal hollow profile 6 , which in the present case consists of a hexagonal aluminum profile with an anodized surface. This hollow profile has longitudinal edges 6 a and intermediate flat side surfaces 6 b. On three of these flat side surfaces 6 b, three cylindrical support rollers 7 are arranged at an angular distance of 120 degrees, the center planes of which extend radially. These support rollers are mounted in bearing blocks 8 , which in turn are interchangeably attached to said side surfaces 6 b. With these support rollers 7 , the chassis 4 is guided exactly concentrically in the pipeline 1 , as can easily be seen in FIG. 1.

In the respective intermediate flat surfaces 6 b are - also at angular intervals of 120 degrees - electrical and mechanical connectors 9 are arranged with a radial direction of insertion. The leads to the plug connections 9 are - not shown here - protected against radiation in the interior of the hollow profile 6th

On the outside, the plug connections 9 lead either directly or, if necessary, via spacers 10 or 11 (see FIG. 8) to three lamps 12 , the axially parallel longitudinal axes of which are located in the planes bisecting the angles between the support rollers 7 . On the side facing away from the pipe 1 of the lamps 12 , which are designed as UV lamps and are additionally provided with an outer lamp bulb 13 , there are reflectors 14 whose radius of curvature is 88 mm to 90 mm and whose axes of curvature are parallel to the pen axes run. The smallest distance between the lamp axes and the reflector surface is 20 mm, the smallest distance between the lamp axes and the inner surface of the renovation hose 2 is 70 mm. The edge lengths of the approximately square reflector are 90 mm each. It has been shown that in the geometric conditions described Ver there is a very uniform irradiation of the inner surface of the renovation hose, in the area of each lamp over a circumference of at least about 60 degrees (based on the tube axis), so that with the in Fig . 1 ge showed lamp and reflector arrangement, a total circumference of the hose remediation of at least about 180 degrees by the UV radiation is applied. The support rollers 7 themselves lie outside the radiation range, so they are at least essentially not hit by the primary radiation and can therefore also reflect no radiation unevenly onto the cleaning hose.

From Fig. 2 it is clear yet, are secured in whatever way the lamps and reflectors on the carrier 5. The reflectors 14 are held at both ends by the plug connections described, wherein in each case one of the two plug connections is a blind plug connection, ie has no electrical contacts, but only serves to mechanically hold the respective reflector end. The other connector 9 is designed as an electrical connector and each electrically and mechanically connected to a lamp socket 15 . It can be seen from FIG. 2 that a very reliable double-ended mounting of the reflector is achieved in this way, and that in particular the lamp 12 is also reliably held with its lamp axis parallel to the axis AA of the carrier 5 .

At the front in the direction of travel of the chassis 4 there is a television camera 16 with which the entire inner surface of the renovation hose 2 can be observed before curing. This makes it possible to check the renovation hose 2 for wrinkle-free installation. This is important insofar as any wrinkling can lead to insufficient hardening of the resin on the one hand, but on the other hand to excessive surface radiation that can lead to hose damage.

At the rear end in the direction of travel there is a plug connection 17 which is designed as a multiple plug and has, for example, 36 plug contacts, all of which need not necessarily be occupied.

The radiation source 3 described so far is equipped with a total of six lamps and reflectors each, which are divided into two groups G1 and G2, of which only one group can be seen in FIG. 1. From Fig. 2 in particular, the carrier is divided by the two groups G1 and G2 according to a first axial region B ₁ and a second axial region B ₂ , which are arranged one behind the other in the direction of travel in the order of their numbering .

In the second axial area B ₂ , the lanps 12 a of the second group G2 were circumferentially offset by half Winkelab, ie by 60 degrees, offset in the circumferential direction relative to the lam pen 12 of the first group G1, in the projection onto a radial Seen on the plane, that is to say arranged “on a gap”, spatially, however, with the axial distance shown in FIG. 2. It follows that in the direction of travel a support roller 7 and a lamp 12 or 12 a are arranged one behind the other, but alternie rend in the reverse order.

Since, according to the statements made above, each of the lam in total a total scope of the renovation Irradiated hose of at least about 180 degrees is there by irradiating the entire scope of the renovation hose of 360 degrees ensured.

The inventive arrangement of support rollers and Lam pen including the lamp reflectors can achieve an extremely compact overall structure, but in particular a very short length of the chassis 4 and thus the entire radiation source 3 , so that it can be easily introduced into underground pipelines that are usually accessible through vertical shafts that would impede the introduction of bulky radiation sources.

From Fig. 3 go forth details of the mounting of the support rollers 7. Each bracket 8 has two to the respective side surface 6 b of the hollow profile 6 parallel and perpendicular to the axis AA of the carrier 5 extending pivot axes 18 and 19 which have a distance D from each other in the axial direction of the carrier 5 . One pivot axis 18 carries a rocker 20 , while the other pivot axis 19 carries a device biased by a spring 21 in the direction of expansion 22 . The arrangement is such that the ends of the rocker 20 and the shock absorber 22 facing away from the bearing block 8 are penetrated by the axis 23 of the respective support roller 7 . It can be seen from the drawing that the shock absorber 22 has a piston rod 24 which carries at its free end a tab 25 which is mounted on the axis 23 together with one leg of the rocker 20 . The distances between the axes 18 , 19 and 23 are chosen so that the bearing block, swing arm and shock absorber describe an acute-angled triangle. In the manner specified, the support roller 7 is always pressed reliably onto the inner surface of the renovation hose 2 , the characteristic curve of the spring 21 being selected such that the proportionate weight of the radiation source is absorbed on the one hand, but there is no inadmissible compression of the renovation hose 2 on the other hand. If such a support roller 7 meets a projection or a recess in the pipeline 1 , this irregularity can be run over without any disadvantages for the positioning of the individual lamps relative to the renovation hose.

As already mentioned in the introduction, it is an object of the invention to be able to convert the radiation source in a simple manner so that it can be used in pipelines of different internal diameters or cross-sectional shapes. Since it may also be necessary for this purpose, the individual support rolls with their bearing blocks to be replaced and replaced by driving elements which allow a greater radial distance between the carrier 5 and the renovation hose 2 , each of the bearing blocks 8 is by means of two headed bolts 26 and 27 are held in the narrowest area of keyhole-shaped axially parallel elongated holes 28 and secured against axial displacement by a locking pin 30 provided with a locking device 29 . This locking pin can consist of a commercially available ball locking pin which has diametrically movable Sperrku gels which are held under spring pressure in their spread position. By means of a handle 31 , such a locking pin can then be pulled out of the carrier 5 while overcoming corresponding retention forces, whereupon the bearing block 8 in question can be lifted off the carrier 5 after longitudinal displacement, ie the heads of the headed bolts 26 and 27 can be removed from the extended area of the Elongated holes 28 are excavated here. It is now possible, for example, to replace the bearing block 8 with one in which the rocker arm 20 and / or the shock absorber 22 have larger or smaller lengths, or in which the support rollers 7 have larger or smaller diameters.

FIG. 4 shows a particularly advantageous solution for the adaptation to un different diameters . The bearing block 8 according to FIG. 3 has been removed from the carrier 5 . On the carrier 5 , a spacer 40 is now attached, which consists of two flange plates 41 and 42 , which are held parallel to each other by radial supports 43 and 44 . The radially inward gene flange plate 41 has two head bolts 45 and 46 which engage in the elongated holes 28 a in the carrier 5 . To secure against axial displacement, a locking pin 30 a is also provided here, which penetrates a surface of the carrier 5 and the flange plate 41 . The radially outward flange plate 42 has in the same relative geometric arrangement as the carrier 5 two elongated holes 28 b with a keyhole shape, in which the head bolts 26 and 27 of the bearing block 8 engage, and a bore 47 for the engagement of the bearing block 8 also belonging Locking pin 30 . The supports 43 and 44 can be replaced by such different lengths.

Fig. 5 shows one of the connectors 9 in put together state. This connector 9 has a nut part 32 , which is shown individually in Fig. 7 and is screwed with its shoulder 32 a against the corresponding flat inner surface of the hollow profile 6 . As a result, a cylindrical extension 32 b projects through the hollow profile 6 to the outside. The extending in the hollow profile 6 supply line 33 is also indicated schematically. The nut part 32 has a ball catch, which has a plurality of balls distributed over the circumference, which are biased radially inwards by corresponding compression springs.

The connector 9 also has a male part 34 , which is shown individually in Fig. 6 and at its engaging in the mut terteil 32 end having a circumferential groove 34 a, which cooperates with the ball detent 48 of the nut part 32 . This interaction is shown in Fig. 5. The father part 34 is also provided with a feed line 35 which leads to the associated lamp holder 15 . The father part 34 can be designed in different lengths and has at its radially outer end a thread 34 b on which the associated reflector 14 and / or the lamp holder 15 can be attached. It can be seen that the plug connection 9 can also be easily released by separating the ball catch 48 , ie the individual lamps and reflectors can be separated from the carrier 5 in the radial direction. The insulating parts of the connector consist of a high-strength Keramikmas se.

The effects of the measures described above are explained in more detail below with reference to FIG. 8:

The sector shown at the top left with a central angle of 120 degrees shows the conditions in accordance with FIG. 1, ie with an inner diameter of the pipeline 1 of 300 mm. The sector shown at the bottom left with a central angle of 120 degrees also shows the conditions when using the radiation source in a pipeline with a diameter of 400 mm. The plug connection 9 is connected to the combination of lamp 12 and reflector 14 via spacers 10 of a correspondingly greater length. The spacers in question are expediently formed in one piece with the father part 34 according to FIG. 5. The swing arm 20 a for the support roller 7 has correspondingly longer legs 36 . The right sector with a central angle of again 120 degrees shows the conditions for a pipe with an inner diameter of 450 mm. In this case, spacers 11 are used with a longer length, and the legs 37 of the rocker 20 b for the storage of the support roller 7 have a longer length. The geometric relationships shown in FIG. 8 must be thought of in analogy to the ratios in FIG. 2. The increase in the distance between the carrier 5 and the lamps 12 or 12 a finds its limit when the total radiation from the lamps 12 or 12 a placed on the gap no longer reaches the entire inner circumference of the renovation hose 2 . In this case, a chassis 4 a with a hollow profile must be used, which allows the equipping with a larger number of lamps 12 or 12 a.

The solution according to FIG. 4 can preferably be used for changing the distance of the support rollers 7 from the support 5 .

Fig. 9 shows the geometric conditions using a chassis 4 a with a carrier 5 a, which consists of a hollow profile 38 with ten longitudinal edges 38 a and ten flat side surfaces 38 b, on which lamps 12 and 12 a and support rollers 7 alternate in the circumferential direction are arranged, again two groups G1 and G2 of five lamps 12 and five lamps 12 a are formed, which are arranged offset in the circumferential direction by half the angular distance between two lamps of the other group. In this way, two groups of five lamps are used in succession when moving the chassis 4 a, so a total of ten lamps, with which the entire inner circumference of the renovation hose is irradiated, so that the resin contained in the renovation hose is cured. Using appropriate assemblies according to FIGS. 4 and 8, the radiation source 3 a according to FIG. 9 can be used for use in pipelines with various internal diameters, and it is possible with a total of ten lamps, a diameter range between 500 and to irradiate 800 mm.

A "central support" 5 or 5 a is understood as a stretched device which has such a distance over its entire length from the inner surface of the renovation hose or the pipeline that lamps with and in the approximately circular space formed thereby without corresponding spacers 10 and 11 who can, the same swing 20 , 20 a and 20 b with accordingly different lengths of the legs 36 and 37 , or with spacers 40 according to FIG. 4. The radius difference between the carrier 5 and the inside of Rehabilitation hose 2 is expediently slightly larger than the diameter of the support rollers 7 , based on the smallest diameter of the pipeline for which the radiation source in question is to be used.

Particular attention should be paid to the reflectors 14 . Sufficient information has already been given above with regard to the geometric design of these reflectors. For example, high-gloss aluminum sheets can be used as the material for these reflectors, but their reflective properties decrease with increasing service life. It is therefore particularly advantageous if the reflectors consist of an infrared-transmissive mineral substrate which has a UV-reflecting coating on the side of the lamps 12 or 12 a. This coating can consist of alternating layers applied in a vacuum from alternating high and low refractive index dielectrics, the thickness of which corresponds approximately to a quarter wavelength of the radiation wavelength that is to be reflected by the reflectors onto the cleaning hose. Layers and substrate, on the other hand, are radiation-permeable to the resulting heat radiation (infrared radiation), which is largely passed in the direction of the support 5 or 5 a and therefore does not contribute to the heating of the renovation hose. Due to the usually unavoidable air losses due to leaks, the rehabilitation hose is flown through by air that is conveyed, which also ensures sufficient cooling of the radiation source.

As can be seen from the above, the radiation source is designed in a modular design, ie the individual components or assemblies are easily interchangeable, and the radiation source can easily be converted to different pipeline diameters by using other assemblies with different lengths of spacers and legs on the bearing blocks will. By using a larger number of lamps, consideration can be given to the surface to be irradiated with larger pipe diameters, so that it is not necessary to use lower pipe speeds for larger pipe diameters in order to compensate for the decrease in the radiation intensity. The chassis can be pulled or provided with its own drive. The cross section of the beam 5 does not necessarily have to be a regular polygon. Hollow sections with non-uniform polygonal cross sections can also be used for pipes with cross sections deviating from the circular shape.
