Keksintö koskee laitetta kumia tai tekoainetta 5 olevien kuljetushihnojen korjaamista ja päättömäksi tekemistä varten, johon laitteeseen kuuluu lämmitettäviä puristinlevyjä, ylemmät poikkipalkit, alemmat poikkipalkit ja hydraulinen paineentasauslaite, jolloin poikkipalkit on yhdistetty pareittain mekaanisen kiristyslait-10 teen omaavien kiristyspulttien avulla ja niihin kohdistuu ennalta asetetun puristuspaineen vaikutuksesta määrätyn taivutuslinjän mukainen taivutusdeformaatio, jolloin edelleen paineentasauslaitteessa on poikkileikkaukseltaan deformoituvia hydrauliikkatyynyjä, jotka on 15 tuettu toisaalta vastaavaan poikkipalkkkiin ja toisaalta poikkipalkkiin nähden välimatkan päähän siirrettävissä olevaan puristinlevyyn rajoittuvaan painelevyyn, jonka maksimaalinen etäisyys poikkipalkista on rajoitettu.The invention relates to a device for repairing and terminating conveyor belts of rubber or synthetic material 5, which device comprises heated press plates, upper crossbeams, lower crossbeams and a hydraulic pressure equalizing device, the crossbeams being connected in pairs by means of mechanical tensioning devices. a bending deformation according to a predetermined bending line, wherein the pressure equalizing device further comprises hydraulic cushions of deformable cross-section supported on the one hand by a corresponding crossbeam and on the other hand by a distance plate limited to a distance from

Tunnetuissa laitteissa on paineentasauslaite usei-20 ta pitkin asianomaista palkkia riviin asetettuja sy- linterimäntälaitteita, jotka on sijoitettu palkkien sisään. Tätä varten tarvitaan palkeissa vastaavat tilat tai poraukset, jotka heikentävät palkkeja, jotka tämän seurauksena on tehtävä raskaiksi ja jäykiksi, vaikka 25 toisaalta kuljetussyistä pyritään erikoisen kevyeen ja taipuisaan rakenteeseen. Myöskään paineensiirto ei tapahdu tasaisesti ja tasaisen homogeenisesti, vaan paine kohdistuu enemmän yksittäisiin, erillisiin sylin-terimäntälaitteisiin liittyviin kohtiin, vaikka yritet-10 täisiin painekengilläkin tasoittaa pintapaineita. Itse sylinterimäntälaitteet vaativat muutaman sadan barin paineen. Tämä kaikki on osoittautunut luotettavaksi, mutta hankalaksi. Muilla tekniikan aloilla, nimittäin paineenalaisten hydraulisten ja pneumaattisten väliai-25 neiden viemiseksi ja ohjaamiseksi tunnetaan ns. hyd- rauliikkaletkut, jotka tosin voidaan painaa kokoon, mut- ____ .. T7.Known devices have a pressure equalizing device several cylinder cylindrical devices arranged in a row along the respective beam and placed inside the beams. This requires corresponding spaces or bores in the beams, which weaken the beams, which as a result have to be made heavy and rigid, although a particularly light and flexible structure is sought for transport reasons. Also, the pressure transfer does not take place evenly and evenly homogeneously, but the pressure is applied more to the individual, separate points associated with the cylinder-piston devices, even if you try to equalize the surface pressures even with pressure shoes. The cylinder piston devices themselves require a pressure of a few hundred bar. All of this has proven to be reliable but tricky. In other fields of technology, namely for conveying and controlling pressurized hydraulic and pneumatic media, the so-called hydraulic hoses, although they can be compressed, but ____ .. T7.

74656 ta joiden kehänpituus ei siitä muutu. Tällaisia hydrau-liikkaletkuja nimitetään kehältään muuttumattomiksi hydrauliikkaletkuiksi. Niitä ei ole tähän saakka käytetty aktiivisina paineentasauslaitteina painetyyny-5 jen toiminnan yhteydessä eikä myöskään aktiivisesti paineensiirtoelementteinä puristimissa, koska ne eivät ole pullistuvia (US-patenttijulkaisu 2 363 779).74656 ta whose circumference does not change. Such hydraulic hoses are called circumferentially modified hydraulic hoses. To date, they have not been used as active pressure relief devices in connection with the operation of pressure pads, nor have they been actively used as pressure transfer elements in presses because they are not bulging (U.S. Pat. No. 2,363,779).

On kuitenkin jo ehdotettu, että samantapaisissa vastaavissa laitteissa ei käytettäisi useita sylin-10 terimäntälaitteistoja, vaan käytettäisiin mieluummin pullistuvia painetyynyjä, mutta tämä rakennemuoto ei kuitenkaan ole käytännössä saavuttanut suosiota. Myöskään ei ole helppo valmistaa painetyynyjä, jotka tarvittavia puristuspaineita vastaanottaessaan ilman muu-15 ta ovat riittävän tiiviitä ja lujia.However, it has already been suggested that similar similar devices would not use multiple cylinder-10 blade piston devices, but would prefer to use bulging pressure pads, but this design has not gained popularity in practice. It is also not easy to manufacture pressure pads which, when otherwise receiving the necessary compression pressures, are sufficiently tight and strong.

Keksinnön tehtävänä on aikaansaada hydraulisella paineentasauslaitteella varustettu laite, jossa ei enää tarvita useita rinnakkaisia sylinterimäntälaitteistoja ja näin ollen puristuspaine on tasaantu-20 nut. Tämän tehtävän ratkaisemiseksi keksinnölle on tunnusomaista, että hydrauliikkatyynyt muodostuvat vierekkäin olevista, kehältään muuttumattomista, defor-moitumattomassa tilassa pyöreän ja käyttötilassa puris-tuspaineen alaisena soikean poikkileikkauksen omaa-25 vista hydrauliikkaletkuista, jotka on taivutuslinjakom-pensaattorin välityksellä tuettu poikkipalkkiin ja/tai vastaavaan puristinlevyyn.The object of the invention is to provide a device with a hydraulic pressure equalization device in which several parallel cylinder-piston devices are no longer required and thus the compression pressure has stabilized. In order to solve this object, the invention is characterized in that the hydraulic pads consist of adjacent, circumferentially deformed, in a deformed state under circular and in operating pressure under compressive pressure, hydraulic hoses with an oval cross-section and an abutment and bending line.

Keksintö lähtee siitä ajatuksesta, että sylin-terimäntälaitteisto voidaan korvata mainituilla hyd-30 rauliikkaletkuilla, vaikka hydrauliikkaletkut ovat kehältään muuttumattomia ja ainoastaan poikkipinnaltaan deformoituja. Tämä korvaaminen on mahdollista, kun on todettu, että hydrauliikkaletkut tukeutuvat le-veäpintaisesti käyttötilanteessa puristuspaineen alai-35 sena, poikkipinnan ollessa suunnilleen soikea ja määritelty, painelevyyn tai palkkiin välillisesti tai vä- 3 74656 littömästi. Välillinen tukeutuminen merkitsee sitä, että tuennassa voi olla vielä välikerroksia, joko lämpöeris-tyskerroksia, tai muita tarkoituksia varten olevia kerroksia. Lisäksi saavutetaan leveäpintaisella tukeutumi-5 sella myös hyvin tasainen ja homogeeninen paineen jakautuminen .The invention starts from the idea that the cylinder-piston apparatus can be replaced by said hydraulic hoses, even though the hydraulic hoses are unchanged in circumference and only deformed in cross section. This substitution is possible when it is found that the hydraulic hoses rest on a wide surface in use under compressive pressure, the cross-section being approximately oval and defined, on the pressure plate or beam indirectly or indirectly. Indirect support means that the support may still have intermediate layers, either thermal insulation layers, or layers for other purposes. In addition, a very even and homogeneous pressure distribution is also achieved with the wide-surface support.

Yksityiskohdissa on keksinnön puitteissa monia mahdollisuuksia keksinnön edelleen kehittämiseen ja muotoiluun. Hyväksi on osoittautunut rakennemuoto, jol-10 le on tunnusomaista, että soikeassa käyttötilanteessa poikkipinta on 25-75 % hydrauliikkatyynyjen muuttumattomasta, pyöreästä poikkipinnasta. On itsestään selvää, että keksinnön puitteissa on pidettävä huoli siitä, että kaikki hydrauliikkaletkut osallistuvat 15 puristuspaineen muodostamiseen samalla tavalla. Tämän vuoksi suositellaan, että laite on sellainen, että käyttötilanteessa kaikki hydrauliikkaletkut ovat muuttaneet muotoaan samassa mitassa ja samalla tavoin.In detail, there are many possibilities for further development and design of the invention within the scope of the invention. The design has proven to be good, characterized in that in the oval operating situation the cross-section is 25-75% of the unchanged, round cross-section of the hydraulic pads. It is self-evident that within the scope of the invention, care must be taken to ensure that all hydraulic hoses participate in the formation of the compression pressure in the same way. It is therefore recommended that the device be such that in use all hydraulic hoses have deformed to the same extent and in the same way.

Jos kaikki hydrauliikkaletkut ovat käyttötilanteessa 20 painuneet palkkien alla koko palkin pituudelta samalla tavoin kokoon, ovat myös pintapuristukset samanlaisia.If, in use 20, all the hydraulic hoses are compressed in the same way over the entire length of the beam under the beams, the surface pressures are also similar.

; Mahdollisimman tasaisen paineenjakautumisen var- ; mistamiseksi on olemassa edullinen keksinnön toteutus- muoto, jossa hydrauliikkaletku on, taivutuslinjakompen-25 saattorien ollessa niiden välissä, kytketty palkkeihin ja/tai vastaaviin painelevyihin. Taivutuslinjakompen-saattorilla, joka on sinänsä tunnettu esim. julkaisusta SU-598 766, tarkoitetaan keksinnön puitteissa välikappaleita, joiden paksuus on suunniteltu niin, että ne 30 kompensoivat palkeille käyttötilanteessa tapahtuvaa taipumista. Taivutuslinjakompensaattori on lisäksi yleensä toiselta puolen tasainen ja toiselta puolen kaareva palkkien taivutuslinjojen summan määrän mukai-sesti käyttötilanteessa. Se voi olla läpimenevä lista 35 tai levy tai myös kokoonpantu erillisistä osakappaleis-ta. Sellainen taivutuslinjakompensaattori on aina tar- 4 74656 koituksenmukainen, kun hydrauliikkaletkut on sijoitettu palkkien kanssa rinnan ja niiden alapuolelle, esim. kaksi rinnakkain olevaa hydrauliikkaletkua palkkia kohti. Taivutuslinjakompensaattori voi kuitenkin myös jää-5 dä pois. Tämä pätee erikoisesti silloin, kun hydrauliikkaletkut on sijoitettu poikittain palkkeihin nähden. Hydrauliikkaletkut ovat keksinnön mukaisessa laitteessa yleensä kytketty hydraulisesti toisiinsa. Puristus-paineen aikaansaamiseksi on olemassa useita mahdolli-10 suuksia. Yhtäältä voi kiristyslaitteisto samalla toimia paineentasauslaitteena. Tällöin ei tarvita mitään erikoista painelähdettä. Toisaalta voidaan toimia myös erikoisen painelähteen, pumpun jne avulla. Keksinnön ilman painelähdettä olevalle toteutusmuodolle on tun-15 nusomaista, että hydrauliikkaletkut on suljettu tiukasti, mutta kuitenkin osalta deformoitumatonta pyöreää poikkileikkaustaan täytetty puristumattomalla nesteellä. Jo mainittu painelevy voi olla suunniteltu lämmönestolaitteeksi tai olla varustettu sellaisella, 20 jos lämmitettyjen puristuslevyjen määräämät lämpötila-olosuhteet sitä vaativat. Puristuspainetta voidaan ilman vaikeuksia tarkkailla ja mitata, samalla kun vähintään yksi hydrauliikkaletku varustetaan vastaavilla osoitinlaitteilla, esim. painemittarilla.; To ensure the most even pressure distribution possible; In order to achieve this, there is a preferred embodiment of the invention in which the hydraulic hose, with the bending line components 25 in between, is connected to beams and / or corresponding pressure plates. Bending line compensator, which is known per se from e.g. SU-598 766, means, within the scope of the invention, spacers whose thickness is designed so as to compensate for the bending of the beams in use. Taivutuslinjakompensaattori is, in general, on one side flat and the other side of the curved beams flex-number-sum in accordance with a use situation. It can be a through-list 35 or a plate or also assembled from separate parts. Such a bending line compensator is always appropriate when the hydraulic hoses are arranged parallel to and below the beams, e.g. two parallel hydraulic hoses per beam. However, the bending line compensator may also be omitted. This is especially true when the hydraulic hoses are arranged transversely to the beams. In the device according to the invention, the hydraulic hoses are generally hydraulically connected to one another. There are several possibilities for providing compression pressure. On the one hand, the clamping device can at the same time act as a pressure equalizing device. In this case, no special pressure source is required. On the other hand, it can also be operated with a special pressure source, pump, etc. The non-pressurized embodiment of the invention is characterized in that the hydraulic hoses are tightly closed, but still partially filled with non-compressible fluid in their non-deformable circular cross-section. The already mentioned pressure plate can be designed as a heat-shielding device or be provided with one if the temperature conditions determined by the heated pressure plates so require. The compression pressure can be easily monitored and measured, while at least one hydraulic hose is provided with corresponding indicating devices, e.g. a pressure gauge.

25 Painemittari voidaan liittää pistoliittimellä ja ottaa pois kuljetuksen ajaksi. Hyvin tasaisen pai-neentuonnin ja paineenjakautumisen saavuttamiseksi suositellaan, että hydrauliikkaletkut muuttuneessa, soikeassa tilassaan ovat tiiviisti vierekkäin.25 The pressure gauge can be connected with a plug connector and removed during transport. In order to achieve a very even pressure supply and pressure distribution, it is recommended that the hydraulic hoses in their altered, oval state be tightly adjacent.

Kuvioissa esitetty laite toimii kumia tai tekoainetta olevan siirtohihnan 1 korjaamista tai 15 päättömäksi tekemistä varten, joka hihna yleensä on vaurstettu vahvistuskerroksella 2. Laitteeseen kuuluvat periaatteellisessa rakenteessa lämmitettävät puris-tinlevyt 3, 4, ylemmät poikkipalkit 5, alemmat poikkipalkit 6 ja hydraulinen, painelähteeseen liitetty hydrau-20 linen paineentasauslaite 7.The device shown in the figures serves to repair or terminate a transfer belt 1 of rubber or artificial material, which belt is generally reinforced by a reinforcing layer 2. The device comprises in principle heated heaters 3, 4, upper crossbeams 5, lower crossbeams 6 and a hydraulic pressurized -20 pressure equalizer 7.

; Palkit 5, 6 on pareittain yhdistetty ruuvipul- : tin muotoisilla kiristyspulteilla 8, joissa on mekaa nisena kiristyslaitteena 9 toimivat mutterit.; The beams 5, 6 are connected in pairs by bolt-shaped clamping bolts 8 with nuts acting as a mechanical clamping device 9.

Kuvien 1-4 mukainen toteutusmuoto on tarkoitettu 25 käytettäväksi painelähteen yhteydessä, jota ei ole piirretty. Voidaan käyttää esim. tavallista pumppua. Palkit 5, 6 taipuvat vallitsevan puristuspaineen vaikutuksesta määritellyn taivutuslinjän 10 mukaisesti.The embodiment according to Figures 1-4 is intended for use in connection with a pressure source which is not drawn. An ordinary pump, for example, can be used. The beams 5, 6 bend under the effect of the prevailing compression pressure according to a defined bending line 10.

Ne on painavuussyistä suunniteltu vastaavasti taipui-30 siksi. Toteutusesimerkissä vaikuttavat hydrauliset paineentasauslaitteet 7 ylemmän puristuslevyn 3 ja ylemmän palkin 5 välissä, kuitenkin niiden välissä on painelevy 12, 15 (vertaa kuvio 4). Kuviossa 2 on muo-• donmuutos esitetty liioiteltuna. Vastaavasti on myös 35 kuviossa 3 esitetty taivutuslinjakompensaattorin 11 ylempi kaareva liitospinta piirretty kaarevuutta liioi- 74656 telien. Paineentasauslaitteessa on monta hydrauliikka-letkua 7, jotka ovat kehältään muuttumattomia, mutta poikkipinnaltaan muuttuvia. Nämä hydrauliikkaletkut 7 tukeutuvat toiselta puolen välillisesti tai välittö-5 mästi vastaaviin palkkeihin 5, toiselta puolen välillisesti tai välittömästi palkkeja 5 vastassa olevaan etäisyydeltään aseteltaviin painelevyihin 12 ja 15, joiden suurin väli A on kulloisenkin vastaavan palkin 5 siten rajoittama, että hydrauliikkaletkujen 7 poik-10 kipinta käyttötilanteessa on soikea. Hydrauliikkaletkut 7 ovat laippojen 15 U-muotoiseksi tekemässä painelevyissä. Suurimman etäisyyden A asettelemiseksi on toteut.usesimerkissä vastaavat etäisyyspultit 13 kiinnitetty painelevyihin 12, ja viety palkkeihin 5. Toteu-15 tusesimerkissä on nämä etäisyyspultit 13 varustettu myös palautusjousilla 14. Itse painelevyissä 12 on jo mainitut sivulaipat 15, niin että hydrauliikkaletkut 7 on tavallaan koteloitu painelevyihin 12. Palautus-jousien 14 tehtävänä on myös painaa nämä sivulaipat 20 15 palkkien 5 alasivua vastaan, niin että laite, var sinkin kuljetuksen ja asennuksen aikana muodostaa suljetun aggregaatin. Sovitus on sellainen, että hydrauliikkaletkut 7 muuttumattomassa tilassaan ovat poikkipinnaltaan pyöreitä, kuten kuvioissa 4 on katkovii-25 voin esitetty, joiden halkaisja D, kuten kuviosta 4 selviää, on suurempi kuin aikaisemmin mainittu suurin etäisyys A. Lopuksi on sovitus sellainen, että hydrauliikkaletkut 7 nojautuvat käyttötilanteessa puris-tuspaineen alaisina soikean poikkipintaisina ja leveä-30 pintaisina painelevyyn 12 tai palkkiin 5. Tämä tukeutuminen voi jälleen tapahtua välillisesti tai välittömästi. Toteutusesimerkissä on hydrauliikkaletkuilla 7 soikeassa käyttötilanteessa poikkipinta, joka on noin 75 % muuttumattomasta pyöreästä poikkipinnasta.They are designed for gravity similarly bent-30 therefore. In the embodiment, the hydraulic pressure equalization devices 7 act between the upper pressure plate 3 and the upper beam 5, however, there is a pressure plate 12, 15 between them (cf. Fig. 4). Figure 2 shows the deformation exaggerated. Correspondingly, the upper curved connecting surface of the bending line compensator 11 shown in Fig. 3 is also drawn with the curvature exaggerated. The pressure equalizing device has a plurality of hydraulic hoses 7 which are constant in circumference but variable in cross-section. The hydraulic tubes 7 are supported on the other side indirectly or immediate-5 ately corresponding to the beams 5, on the other side indirectly or directly beams to a distance which is settable and the pressure plates 5 facing 12 and 15 with a maximum spacing A is the respective equivalent of the beam 5 so limited that the hydraulic hoses 7 excep-10 the spark in use is oval. The hydraulic hoses 7 are in the pressure plates made by the flanges 15 in a U-shape. In order to set the maximum distance A, in the exemplary embodiment the corresponding distance bolts 13 are attached to the pressure plates 12, and passed to the beams 5. In the embodiment 15, these distance bolts 13 are also provided with return springs 14. The pressure plates 12 themselves already have said side flanges 15, so that the hydraulic hoses 7 are 12. The return springs 14 also have the function of pressing these side flanges 20 15 against the underside of the beams 5, so that the device, especially during transport and installation, forms a closed unit. The arrangement is such that the hydraulic hoses 7 in their unchanged state have a circular cross-section, as shown in Fig. 4 by broken lines, the diameter D of which, as shown in Fig. 4, is larger than the previously mentioned maximum distance A. Finally, the arrangement is such that the hydraulic hoses 7 rest in use, under compression pressure in the form of an oval cross-section and a wide-30 surface in the pressure plate 12 or in the beam 5. This support can again take place indirectly or immediately. In the embodiment, the hydraulic hoses 7 have an cross-section in the oval operating situation which is approximately 75% of the unchanged circular cross-section.

35 Alussa jo mainituista syistä on toteutusesimerkki (ei kuitenkaan välttämättä) varustettu taivutuslinjakompen-35 For the reasons already mentioned at the outset, the implementation example is (but not necessarily) equipped with a bending line

7 74656 saattorilla 11, joka toteutusesimerkissä on sijoitettu palkkien 5 ja hydrauliikkaletkujen 7 väliin. - Esitetty ei ole sitä, että hydrauliikkaletkut 7 on yhdistetty keskenään eikä sitä, kuinka yhdistys on tehty. Ne on 5 liitetty yhteiseen painelähteeseen. Muuten hydrauliikkaletkut 7 sijaitsevat toteutusesimerkissä rinnan palkkeihin 5 nähden ja niiden alla. Palkkia kohti on varattu kaksi hydrauliikkaletkua 7. Ne voisivat olla myös poikittain palkkeihin 5 nähden, kuten kuviossa 1 on esi-10 tetty. Tällöin hydrauliikkaletkut 7 yhdistävät viereiset palkit 5. Hydrauliikkaletkuja 7 ei tarvitse varsinaisesti tukea palkkien 5 välisellä alueella. Painelevy 12 on samalla suunniteltu lämmöneristyslaitteeksi tai varustettu sellaisella. Painemittari 16, joka on 15 pistoliittimellä tai vastaavalla yhdistetty yhteen hydrauliikkaletkuun 7, tarkkailee puristuspainetta. Käyttötilanteessa on hydrauliikkaletkut 7 yleensä tiiviisti vierekkäin, kuten kuvio 4 osoittaa. Taivutus-linjankompensaattori 11 kompensoi ylempien palkkien 20 5 ja alempien palkkien 6 taipuman, tarkemmin sanottu na taipumalinjän. Valmistusteknillisistä syistä voi .| taivutuslinjakompensaattorin alasivu kuormittamatto massa tilassa olla tasainen (kuvio 3). Se muuttuu sitten käyttötilanteessa poikkipinnaltaan melkein linssin-25 muotoiseksi.7 74656 with an actuator 11, which in the embodiment is placed between the beams 5 and the hydraulic hoses 7. - It is not shown that the hydraulic hoses 7 are connected to each other or how the connection is made. They are 5 connected to a common pressure source. Otherwise, in the embodiment, the hydraulic hoses 7 are located parallel to and below the beams 5. Two hydraulic hoses 7 are provided per beam. They could also be transverse to the beams 5, as shown in Fig. 1. In this case, the hydraulic hoses 7 connect the adjacent beams 5. The hydraulic hoses 7 do not actually need to be supported in the area between the beams 5. At the same time, the pressure plate 12 is designed or equipped as a thermal insulation device. The pressure gauge 16, which is connected to one hydraulic hose 7 by means of 15 plug connectors or the like, monitors the compression pressure. In use, the hydraulic hoses 7 are generally closely adjacent, as shown in Figure 4. The bending line compensator 11 compensates for the deflection of the upper beams 20 5 and the lower beams 6, more specifically the deflection line na. For reasons of manufacturing technology, the underside of the bending line compensator in the unloaded mass state shall be flat (Figure 3). It then changes in shape to a lens-25 in cross-section in use.

Kuvioissa 5-7 on esitetty keksinnön toteutus-muoto, joka toimii ilman painelähdettä, pumppua tai vastaavaa. Kuvion 5 ja 6 vertailevassa tarkastelussa huomataan ensinnäkin, että myös täällä hydrauliiikka-30 letkut 7 on tuettu asettamalla mainittu taivutuslinja-kompensaattori 11 palkkien 5, 6 ja vastaavan painelevyn 12 väliin. Se kompensoi jo kuvatulla tavalla palkkien 5, 6 taipumat käyttötilanteessa. Kuvasta 6 huomataan, että hydrauliikkaletkut 7, jotka tässä toteutus-35 muodossa ovat suljetut, ovat muuttumattoman pyöreän poikkipintansa (kuvio 6) määrättyyn osaan saakka täy- 8 74656 tetyt puristumattomalla nesteellä 17. Kiristyspulttien 8 kiristyslaite 9 on samalla suunniteltu paineenta-sauslaitteen ohjauslaitteeksi. Kiristyspultit 8 ovat ruuvipultteja, joissa on kiristyslaitteena ruuviavai-5 mella kiristettävät mutterit 9, joiden yhteydessä voidaan käyttää kuulalaakeria, aluslevyjä tai muita kitkaa vähentäviä laitteita. Hydrauliikkaletkujen 7 sisäosat voivat olla toistensa kanssa yhteydessä. Koska hydrauliikkaletkut 7 ovat tiiviisti suljetut, on ne 10 päistään varustettu välineillä 19, joilla tämä sulkeminen tapahtuu. Mikäli hydrauliikkaletkut 7 ovat yhteydessä keskenään, on näihin välineisiin 19 sijoitettu myös kanavia näitä yhteyksiä varten. Puristuspai-netta voidaan yksinkertaisella tavalla seurata mittaa-15 maila, kun jo selostettua kiristyslaitetta 9 ohjataan. Tätä varten on vähintään yhteen hydrauliikkaletkuun 7 liitettävä painemittari 16 tai vastaava. Se tapahtuu tarkoituksenmukaisimmin pistokytkimellä, jotta paineen osoitinlaite 16 keksinnön mukaista laitetta 20 kokonaisuutena paikasta toiseen siirrettäessä voidaan ottaa pois. Toteutusesimerkki on suunniteltu siten, että hydrauliikkaletkut 7 on sijoitettu rinnan palkkien 5, 6 kanssa ja palkkien 5, 6 alle, ja nimenomaan kaksi hydrauliikkaletkua 7 palkkia 5 tai 6 kohti. Pe-25 riaatteessa voitaisiin hydrauliikkaletkut 7 sijoittaa myös poikittain palkkeihin 5, 6 nähden. Kuvioiden 6 ja 7 vertailevassa tarkastelussa huomataan, että hydrauliikkaletkut 7 on täytetty noin 75 %:iin saakka niiden muuttamattomasta pyöreästä poikkipinnasta pu-30 ristumattomalla nesteellä 17. Kuviosta 7 huomataan, että ne muotoa muuttaneessa tilassa ovat tiiviisti rinnakkain, minkä johdosta saavutetaan hyvin tasainen paineen jakautuminen. Tulokset ovat vahvistaneeet, että hydrauliikkaletkujen 7 kaikilla poikkipinnoilla 35 vastaavien palkkien 5, 6 alla ja että kaikilla hyd- rauliikkaletkuilla 7 käyttötilanteessa on sama poikki-Figures 5-7 show an embodiment of the invention operating without a pressure source, pump or the like. In a comparative examination of Figures 5 and 6, it is firstly noted that here too the hydraulic hoses 7 are supported by placing said bending line compensator 11 between the beams 5, 6 and the corresponding pressure plate 12. It compensates for the deflections of the beams 5, 6 in the operating situation, as already described. It can be seen from Fig. 6 that the hydraulic hoses 7, which in this embodiment are closed, are filled to a certain part of their constant circular cross-section (Fig. 6) with non-compressible fluid 17. The clamping device 9 of the clamping bolts 8 is at the same time designed as a pressure-drying device control device. Tightening bolts 8 are screw bolts with nuts 9 which can be tightened with a screwdriver as a tightening device, in connection with which ball bearings, washers or other devices reducing friction can be used. The inner parts of the hydraulic hoses 7 can be in contact with each other. Since the hydraulic hoses 7 are tightly closed, they are provided at their ends 10 with means 19 by which this closing takes place. If the hydraulic hoses 7 are in communication with each other, channels for these connections are also arranged in these means 19. The compression pressure can be monitored in a simple manner with a gauge of 15 rows when the already described clamping device 9 is controlled. For this purpose, a pressure gauge 16 or the like must be connected to at least one hydraulic hose 7. This is most conveniently done with a plug switch, so that the pressure indicating device 16 can be removed as a whole when the device 20 according to the invention is moved from one place to another. The embodiment is designed in such a way that the hydraulic hoses 7 are arranged in parallel with the beams 5, 6 and under the beams 5, 6, and in particular with the two hydraulic hoses 7 per beam 5 or 6. In principle, the hydraulic hoses 7 could also be arranged transversely to the beams 5, 6. A comparative examination of Figures 6 and 7 shows that the hydraulic hoses 7 are filled up to about 75% of their unchanged circular cross-section with a non-crossed fluid 17. Figure 7 shows that they are tightly parallel in the deformed state, resulting in a very uniform pressure distribution . The results have confirmed that all cross-sections 35 of the hydraulic hoses 7 under the respective beams 5, 6 and that all hydraulic hoses 7 have the same cross-section in use.

IIII

9 74656 pinnan muoto ja siten samanlainen kokoonpainuminen, niin että tuloksena toimii kaikkialla saman paineinen painepatja ja tasainen sekä riittävän homogeeninen paineen jakautuminen saadaan varmistetuksi. Hydrauliikka-5 letkuissa 7 oleva ilmapatja, jolla on ulkoilmaan nähden yli- tai alipaine, ei haittaa kuvattua toimintaa.9 74656 surface shape and thus a similar compression, so that the result is a pressure mattress operating at the same pressure everywhere and a uniform and sufficiently homogeneous pressure distribution is ensured. An air mattress in the hydraulic-5 hoses 7 with an overpressure or underpressure relative to the outside air does not interfere with the described operation.

Sekä kuvioiden 1-4 mukaisessa että myös kuvioiden 5 ja 7 mukaisessa toteutusmuodossa voidaan toimia myös ilman taivutuslinjakompensaattoria 11.In both the embodiment according to Figures 1 to 4 and also in the embodiment according to Figures 5 and 7, it is also possible to operate without the bending line compensator 11.
