Inrichting voor het repareren en eindloos maken van transportbanden .Device for repairing and making conveyor belts endless.

De uitvinding heeft betrekking op een inrichting voor het repareren en eindloos maken van transportbanden uit rubber of kunststof (met inwendige versterkingen), met verwarmbare persplaten, bovenste dwarsbalken, onderste 5 dwarsbalken en een hydraulische persdrukopwekinrichting, waarbij de dwarsbalken paarsgewijs door spanbouten met een mechanische spaninrichting zijn verenigd en door de voorafbepaalde persdruk een buigvervorming met een bepaalde buig-lijn verkrijgen, waarbij verder tussen ëën van de persplaten IQ en de bijbehorende dwarsbalken de persdrukopwekinrichting werkt.The invention relates to a device for repairing and making endless conveyor belts of rubber or plastic (with internal reinforcements), with heatable pressing plates, upper cross beams, lower cross beams and a hydraulic compression pressure generating device, the cross beams in pairs by tension bolts with a mechanical tensioning device are combined and obtain a bending deformation with a certain bending line through the predetermined pressing pressure, the pressing pressure generating device further acting between one of the pressing plates IQ and the associated crossbeams.

De spanbouten zijn in het algemeen schroefbouten, die met behulp van bijbehorende moeren spanbaar zijn. Overigens zijn bij dergelijke persen de dwarsbalken in het 15 algemeen om gewichtsredenen vervormbaar uitgevoerd, zodat het totale systeem als het ware buigslap is. Werkt de persdrukopwekinrichting tussen ëën van de persplaten en de bijbehorende dwarsbalken, dan vervormen de bovenste en onderste dwarsbalken zich en wel naargelang van de voorafbepaalde, in 2Q wezen boogvormige buiglijn.The clamping bolts are generally screw bolts, which can be clamped with the aid of associated nuts. Incidentally, in such presses, the cross beams are generally deformable for weight reasons, so that the entire system is as it were bending slack. If the press-pressure generating device operates between one of the press-plates and the associated cross-members, the upper and lower cross-members deform according to the predetermined, essentially arcuate, bending line.

Bij de (uit de praktijk) bekende inrichtingen van deze soort bezit de persdrukopwekinrichting een groo.t aantal van langs de bijbehorende dwarsbalk op een rij aangebrachte ctlinderzuigerinrichtingen, die in de dwars-25 balken zijn ingezet. Daartoe zijn overeenkomstige uitsparingen of boringen in de dwarsbalken nodig, waardoor de dwarsbalken verzwakt worden, die dientengevolge dienovereenkomstig zwaar en stabiel moeten worden uitgevoerd, hoewel anderzijds, zoals reeds werd vermeld, een bijzonder lichte en buigslappe 3Q bouwwijze om transportredenen wordt nagestreefd. Ook geschiedt de drukopbrenging niet gèlijkmatig en als het ware homogeen, maar veeleer op afzonderlijke, aan de afzonderlijke cilinderzuigerinrichtingen toegevoerde plaatsen, waar men ook via drukschoenen probeert om de vlaktedrukken te verminderen.In the devices of this type (known in practice), the press-pressure generating device has a large number of cylinder piston devices arranged in a row along the associated crossbar, which are inserted in the crossbeams. For this purpose, corresponding recesses or bores in the cross beams are required, thereby weakening the cross beams, which consequently have to be made heavy and stable, although, on the other hand, as already mentioned, a particularly light and bend-slack construction is sought for transport reasons. Nor is the pressure applied uniformly and, as it were, homogeneous, but rather at separate locations supplied to the individual cylinder piston devices, where attempts are also made via pressure shoes to reduce the surface pressures.

35 De zuigercilinderinrichtingen zelf moeten met drukken van enige honderden bar belast worden. Dit alles heeft in de praktijk wel voldaan, maar is kostbaar.The piston cylinder devices themselves must be loaded with pressures of several hundred bar. All this has worked in practice, but is expensive.

Op andere gebieden van de techniek, namelijk, voor het geleiden van vol onder druk staande hydraulische, en pneumatische media kent men z.g. hydraulische slangen, die wel,.samendrukbaar zijn, maar waarbij de omtrek niet verandert 5 bij een dergelijke vervorming. Dergelijke hydraulische. slan-3 gen worden aangeduid .als hydraulische slangen met een stabiele omtrek.„Ze zijn tot nu toe als actieve drukopwekkers met de functie van een drukkussen of ook alleen als actieve druk-overbrengende elementen in persen niet toegepast, daar ze IQ niet opblaasbaar zijn.In other fields of the art, namely, for guiding fully pressurized hydraulic and pneumatic media, so-called hydraulic hoses are known, which are compressible, but the circumference does not change with such deformation. Such hydraulic. hoses are referred to as hydraulic hoses with a stable circumference. "They have hitherto not been used as active pressure generators with the function of a pressure pad or also only as active pressure-transmitting elements in presses, since they are not inflatable .

Wel is bij dergelijke inrichtingen reeds voorgesteld, niet te werken met een groot aantal op een rij aangebrachte cilinder zuigerinrichtingen,' maar met opblaasbare drukkussens, maar deze uitvoeringsvorm heeft zich in de 15 praktijk niet doorgezet. Ook laten zich niet gemakkelijk drukkussens vervaardigen, die bij opname van de vereiste persdrukken zonder meer voldoende dicht en stevig zijn.It has already been proposed with such devices not to work with a large number of cylinder piston devices arranged in a row, but with inflatable pressure pads, but this embodiment has not continued in practice. It is also difficult to manufacture pressure pads which are readily sufficiently dense and sturdy when the required pressures are absorbed.

De uitvinding beoogt een dergelijke met een hydraulische persdrukopwekinrichting uitgeruste inrichting te 20 verschaffen, waarbij een groot aantal van op een rij aangebrachte cilinderzuigerinrichtingen niet meer nodig is en daarenboven de persdruk gelijkmatig gemaakt is.The object of the invention is to provide such a device equipped with a hydraulic pressure-generating device, wherein a large number of cylinder piston devices arranged in a row are no longer necessary and, moreover, the pressure is made uniform.

Om dit doel te bereiken wordt volgens de uitvinding voorgesteld, dat de persdrukopwekinrichting hy-25 draulische slangen met een stabiele omtrek maar vervormbare dwarsdoorsnede bezit, die enerzijds aan de bijbehorende dwarsbalk zijn ondersteund, en anderzijds in een ten opzichte van de dwarsbalk in afstand verstelbare, als U-profiel uitgevoerde drukplaat zijn opgenomen, waarbij de afstand van de 30 drukplaten vanaf hun dwarsbalk zo is gekozen, dat de hydraulische slangen in de bedrijfstoestand een ovale dwarsdoorsnede hebben.In order to achieve this object, it is proposed according to the invention that the compression pressure generating device has hydraulic hoses with a stable circumference but deformable cross section, which are supported on the one hand on the associated cross beam, and on the other hand in a distance which is adjustable relative to the cross beam. pressure plates in the form of a U-profile are included, the distance of the pressure plates from their cross beam being chosen such that the hydraulic hoses have an oval cross-section in the operating condition.

De uitvinding gaat uit van het inzicht, dat hij een dergelijke inrichting genoemde hydraulische slangen 35 de gebruikelijke zuigercilinderinrichtingen kunnen vervangen, hoewel de hydraulische slangen een stabiele omtrek hebben en alleen in dwarsdoorsnede vervormbaar zijn. Deze vervanging is mogelijk, wanneer gewaarborgd is, dat de hydraulische slangen in de bedrijfstoestand onder de persdruk met in wezen een 4Q ovale bepaalde dwarsdoorsnede aan de drukplaat resp. aan de 8103276 «. ί -3- dwarsbalk indirect of direct met een breed vlak zijn ondersteund. Indirect betekent, dat voor de ondersteuning nog tussenlagen kunnen zijn aangebracht, zij het voor'warmte-isolatiedoelen, zij het voor andere doelen. Overigens be-5 reikt men via de ondersteuning met een breed vlak ook een zeer gelijkmatige en homogene drukverdeling.The invention is based on the recognition that he can replace such hydraulic devices mentioned hydraulic hoses 35 with the usual piston cylinder devices, although the hydraulic hoses have a stable circumference and are only deformable in cross section. This replacement is possible if it is ensured that the hydraulic hoses in the operating state are under the baling pressure with essentially a 4 Oval determined cross-section on the pressure plate or. on the 8103276 «. ί -3- crossbars are supported indirectly or directly with a wide plane. Indirectly means that intermediate layers can be provided for the support, albeit for heat insulation purposes, albeit for other purposes. Incidentally, a very uniform and homogeneous pressure distribution is also achieved via the support with a wide surface.

In detail bestaan binnen het kader van de uitvinding meerdere mogelijkheden bij de verdere uitvoering en vormgeving. Goed voldaan heeft een uitvoeringsvorm, die IQ is gekenmerkt, doordat de ovale bedrijfstoestand een dwarsdoorsnede heeft, die tussen 25 en 75% van de onvervormde ronde dwarsdoorsnede van de hydraulische slangen ligt. Natuurlijk moet binnen het kader van de uitvinding gezorgd worden, dat alle hydraulische slangen op gelijke wijze bij-25 dragen voor het opwekken van de persdruk. Daartoe verdient het aanbeveling de inrichting zo uit te voeren, dat in de bedrijfstoestand alle hydraulische slangen in gelijke mate en op gelijke wijze vervormd zijn. Ondergaan alle hydraulische slangen onder de dwarsbalken in de bedrijfstoestand 2Q over de' totale lengte van de dwarsbalken dezelfde samen-drukking, dan verkrijgt men ook gelijke vlaktedrukken.In detail, within the scope of the invention there are several possibilities in the further design and design. An embodiment characterized by IQ is well satisfied in that the oval operating state has a cross-section which is between 25 and 75% of the undeformed round cross-section of the hydraulic hoses. Of course, within the scope of the invention, it must be ensured that all hydraulic hoses contribute in an equal manner to generate the baling pressure. To this end, it is recommended to design the device in such a way that, in the operating condition, all hydraulic hoses are deformed equally and in the same manner. If all hydraulic hoses under the crossbars in the operating state 2Q undergo the same compression over the total length of the crossbars, the same surface pressures are also obtained.

Om een zo gelijkmatig mogelijke drukverdeling te waarborgen, is een bij voorkeur toegepaste uitvoeringsvorm -van de uitvinding, waaraan bij zondere betekenis 25 toekomt, gekenmerkt doordat de hydraulische slangen onder tussenschakeling van een buiglijncondensator aan de dwarsbalken en/of aan de bijbehorende drukplaten zijn aangesloten. Buiglijncompensator betekent binnen het kader van de uitvinding tussenlagen, waarvan de dikte zö is ingericht, 3Q dat ze de doorbuiging compenseren die de dwarsbalken in de bedrijfstoestand ondergaan. Een buiglijncompensator is daartoe in het algemeen aan één zijde vlak en aan de andere naargelang van de som van de buiglijnen van de dwarsbalken in de bedrijfstoestand gekromd. Deze kan als doorlopende 35 lijst of plaat zijn uitgevoerd of zijn samengesteld uit afzonderlijke deelstukken. Een dergelijke buiglijncompensator is steeds doelmatig, wanneer de hydraulische slangen evenwijdig aan de dwarsbalken en daaronder aangebracht zijn, bijvoorbeeld twee naast elkaar liggende hydraulische slangen 40 per dwarsbalk. Een buiglijncondensator kan echter ook ont- 81 03 2 7 6 -4- V * breken. Dit geldt in het bijzonder wanneer de hydraulische slangen dwars op de dwarsbalk, zijn aangebracht. Overigens zijn de hydraulische 'slangen bij een inrichting volgens de uitvinding in het algemeen hydraulisch met elkaar verbonden.In order to ensure a pressure distribution which is as uniform as possible, a preferred embodiment of the invention, which is of particular significance, is characterized in that the hydraulic hoses are connected to the cross beams and / or to the associated pressure plates under the interposition of a bending line capacitor. Bending line compensator within the scope of the invention means intermediate layers, the thickness of which is so arranged, that they compensate for the deflection that the crossbars undergo in the operating state. For this purpose, a bending line compensator is generally flat on one side and curved in the operating state on the other according to the sum of the bending lines of the crossbars. This can be in the form of a continuous strip or plate or it can be composed of separate parts. Such a bending line compensator is always effective when the hydraulic hoses are arranged parallel to the cross beams and underneath them, for example two adjacent hydraulic hoses 40 per cross beam. However, a bending line capacitor can also break 81 03 2 7 6 -4-V *. This applies in particular when the hydraulic hoses are arranged transversely of the cross beam. Incidentally, the hydraulic hoses in a device according to the invention are generally hydraulically connected to each other.

5 Om de persdruk op te wekken bestaan meerde re mogelijkheden. Enerzijds kan de 'spaninrichting tegelijk als persdrukopwekinrichting worden toegepast. Dan is er geen hijzonde%drukmiddelbron nódig. Anderzijds kan ook worden gewerkt met een bij zonden drukmiddelbron in de vorm van een IQ pomp of dergelijke. Voor een uitvoeringsvorm zonder drukmiddelbron is de uitvinding gekenmerkt, doordat de hydraulische slangen vast afgesloten zijn en alleen voor een deel van hun onvervormde ronde hydraulische slangdwarsdoorsneden zijn gevuld met een incompressibele vloeistof, waarbij de spaninrich-15 ting van de spanbouten tegelijk als bedieningsinrichting van de persdrukopwekinrichting is uitgevoerd. De andere uitvoeringsvorm is gekenmerkt, doordat de hydraulisch met elkaar verbonden drukmiddelslangen zijn aangesloten aan een gemeenschappelijke drukmiddelbron.5 There are several options for generating the baling pressure. On the one hand, the clamping device can be used simultaneously as a pressure-generating device. Then there is no need for a% source of pressure medium. On the other hand, it is also possible to work with an incident pressure medium source in the form of an IQ pump or the like. For an embodiment without a pressure medium source, the invention is characterized in that the hydraulic hoses are tightly closed and only part of their undeformed round hydraulic hose cross sections are filled with an incompressible liquid, the clamping device of the clamping bolts simultaneously acting as an actuating device of the press-generating device is carried out. The other embodiment is characterized in that the hydraulically connected pressure medium hoses are connected to a common pressure medium source.

20. De reeds genoemde drukplaat kan tegelijk als warmte-isolatie-inrichting zijn uitgevoerd of van een dergelijke inrichting zijn voorzien, wanneer de door' de verwarmde persplaten bepaalde temperatuuromstandigheden dit verlangen. De persdruk laat zich zonder moeilijkheden controleer-25 baar en meetbaar maken, doordat men ten minste ëén van de hydraulische slangen voorziet van een overeenkomstige aanwijs-inrichting, bijvoorbeeld in de vorm van een manometer. Daarbij kan de manometer ook met steekkoppelingen aangesloten zijn en daardoor voor transportdoelen afneembaar zijn. Om 30 een zeer gelijkmatige ." · drukinleiding en drukverdeling te bereiken, beveelt de uitvinding aan,· dat de afzonderlijke hydraulische slangen in de vervormde ovale toestand dicht tegen elkaar aanliggen.20. The aforementioned printing plate can at the same time be designed as a heat insulation device or be provided with such a device if the temperature conditions determined by the heated pressing plates so require. The baling pressure can be made controllable and measurable without difficulty, by providing at least one of the hydraulic hoses with a corresponding indicating device, for example in the form of a manometer. The pressure gauge can also be connected with plug-in couplings and can therefore be removed for transport purposes. In order to achieve a very uniform pressure initiation and pressure distribution, the invention recommends that the individual hydraulic hoses lie close together in the deformed oval state.

Hierna wordt de uitvinding aan de hand van 35 de tekening nader töegelicht, die slechts een uitvoerings-voorheeld voorstelt. In schematische afbeelding tonen fig. 1 een bovenaanzicht op een inrichting volgens de uitvinding,The invention will be explained in more detail below with reference to the drawing, which represents only an embodiment.

De in de figuren afgebeelde inrichting dient 25 voor het repareren en eindloos maken van transportbanden uit rubber of kunststof, die in het algemeen inwendige versterkingen 2 bezitten. Tot de inrichting behoren in zijn principiële opbouw verwarmbare persplaten 3, 4, een bovenste dwarsbalk 5, een onderste dwarsbalk 6 en een hydraulische, aan een 20 drukmiddelbron aangesloten persdrukopwekinrichting 7.The device shown in the figures serves to repair and make endless conveyor belts of rubber or plastic, which generally have internal reinforcements 2. In its basic construction, the device comprises heatable press plates 3, 4, an upper cross beam 5, a lower cross beam 6 and a hydraulic press pressure generating device 7 connected to a source of pressure medium.

De dwarsbalken 5,6 zijn paarsgewijze door spanhouten 8 in de vorm van schroefbouten met mechanische spaninrichtingen 9 in de vorm van opgezette moeren verenigd.The crossbars 5,6 are joined in pairs by clamping bolts 8 in the form of screw bolts with mechanical clamping devices 9 in the form of mounted nuts.

De uitvoeringsvorm van fig. 1-4 is voor werken 25 met een drukmiddelbron ingericht, maar de drukmiddelbron werd niet getekend. Het kan om een gebruikelijke pomp gaan. De dwarsbalken 5,6 ondervinden door de voorafbepaalde persdruk een buigvervorming met een bepaalde buiglijn 10. Zé~zijïi om gewichtsredenen dienovereenkomstig buigslap uitgevoerd. In 30 het uitvoeringsvoorbeeld werken de persdrukopwekinrichtingen 7 tussen de bovenste persplaat 3 en de bovenste dwarsbalken 5 maar onder tussenschakeling van een drukplaat 12, 15 (vergelijk fig. 4}. In fig. 2 is de vervorming overdreven afgebeeld. Dienovereenkomstig is ook de in fig. 3 afgebeelde buiglijn-35 compensator 11 wat betreft het bovenste boogvormige aansluit-vlak overdreven getekend,The embodiment of FIGS. 1-4 is adapted for working with a pressure medium source, but the pressure medium source has not been drawn. It can be a usual pump. The crossbars 5,6 experience a bending deformation with a certain bending line 10 due to the predetermined pressing pressure. They are designed accordingly for weight reasons. In the exemplary embodiment, the compression pressure generating devices 7 operate between the upper compression plate 3 and the upper crossbars 5 but with the interposition of a printing plate 12, 15 (compare figure 4}. In figure 2 the deformation is exaggerated. 3 bendline-35 compensator 11 shown in an exaggerated manner with regard to the upper arc-shaped connecting surface,

De persdrukopwekinrichting bezit meerdere hydraulische slangen 7 met stabiele omtrek, maar vervormbare dwarsdoorsneden. Deze hydraulische slangen 7 zijn enerzijds 40 indirect of direct aan de bijbehorende dwarsbalken 5 onder- 81 0 3 2 7 6The compression pressure generating device has a plurality of hydraulic hoses 7 with a stable circumference, but deformable cross sections. These hydraulic hoses 7 are on the one hand 40 indirectly or directly on the associated crossbars 5 underneath 81 0 3 2 7 6

-6- ‘ steund en anderzijds indirect of direct aan een ten opzichte van de dwarsbalk 5 in afstand verstelbare drukplaat 12, 15 ondersteunt, waarvan de maximale 'afstand A vanaf de telkens bijbehorende dwarsbalk 5 zo is· beperkt, dat de hydraulische 5 slangen 7 in de bedriifstoestand een ovale dwarsdoorsnede hebben. De hydraulische slangen 7 liggen in de door de flenzen 15 in profiel U-vormige drukplaten. Voor het instellen van de maximale afstand A zijn in het uitvoeringsvoorbeeld overeenkomstige afstandsbouten 13 aan de druk-10. plaat 12 aangesloten, die zijn gevoerd in de dwarsbalken 5.-6- 'and, on the other hand, supports indirectly or directly on a pressure plate 12,15 which is adjustable relative to the cross beam 5, the maximum distance of which A from the respective cross beam 5 is so limited that the hydraulic hoses 7 have an oval cross-section in the operating condition. The hydraulic hoses 7 lie in the U-shaped pressure plates formed by the flanges 15 in profile. In the exemplary embodiment, for setting the maximum distance A, corresponding spacing bolts 13 are attached to the pressure-10. plate 12 connected, which are lined in the crossbars 5.

In het uitvoeringsvoorbeeld zijn deze afstandsbalken 13 ook voorzien van terugstelvefen 14. De drukplaten 12 zelf bezitten de reeds genoemde zijdelingse flenzen 15, zodat de hydraulische slangen 7 in de drukplaten als het ware zijn opge-15 sloten, De terugstelveren 14 dienen ook om deze zijdelingse flenzen 15 tegen de onderzijde van de dwarsbalken 5 te drukken, zodat het aggregaat, in het bijzonder bij het transport en bij de montage, een gesloten aggregaat vormt. De inrichting is zo uitgevoerd, dat de hydraulische slangen 7 in on-2Q. vervormde toestand een ronde, in fig. 4 met streepjes en punten getekende hydraulische dwarsdoorsnede hebben, waarvan de diameter D, zoals in fig. 4 zichtbaar is, groter is dan de bovengenoemde maximale afstand A. Tenslotte is de inrichting zo uitgevoerd, dat de hydraulische slangen 7 in de be-25 drijfstoestand onder de persdruk met in wezen ovale dwarsdoorsneden aan de drukplaat 12 resp. aan de dwarsbalk 5 met een breed vlak zijn ondersteund. Deze ondersteuning kan weer indirect of direct geschieden. In het uitvoeringsvoorbeeld bezitten de hydraulische slangen 7 in de ovale bedrijfstoe-3Q stand een dwarsdoorsnede, die ongeveer 75% van de onvervormde ronde dwarsdoorsnede uitmaakt. Om de in het voorgaande reeds toegelichte redenen is in het uitvoeringsvoorbeeld (maar niet noodzakelijkl een buiglijncompensator 1.1 aangebracht, die in het uitvoeringsvoorbeeld tussen de dwarsbalken 5 en 35 de hydraulische slangen 7 is aangebracht. Niet afgebeeld werdf dat en hoe de hydraulische slangen 7 met elkaar zijn verbonden, Ze zijn aan een gemeenschappelijke drukmiddelbron aangesloten. Overigens verlopen in het uitvoeringsvoorbeeld de hydraulische slangen 7 evenwijdig aan de dwarsbalken 5 en 4Q daaronder. Per dwarsbalk 5 zijn twee hydraulische slangen 7 8103276 -7- • aangebracht. Ze zouden ook dwars op de dwarsbalken 5 kunnen verlopen zoals is aangegeven in fig. 1. Daarbij lopen de hydraulische slangen 7 onder deze dwarsbalken 5 en overbruggen ze de ruimte tussen naburige dwarsbalken 5. Een bijzondere 5 ondersteuning van de hydraulische slangen 7 in de zone tussen de dwarsbalken 5 is niet nodig. De drukplaat 5 is tegelijk als warmte-isolatie-inrichting uitgevoerd of van een dergelijke inrichting voorzien. Een manometer 16/ die met een steekkoppeling of dergelijke aan één van de hydraulische 10 slangen 7 is aangesloten/ dient om de persdruk te controleren. In de bedrijfstoestand liggen de hydraulische slangen 7 overigens dicht tegen elkaar aan/ zoals fig. 4 toont. De buiglijncompensator 11 compenseert de doorbuiging, nauwkeuriger de buiglijnen/ van de bovenste dwarsbalken 5 en van 15 de onderste dwarsbalken 6. Desalniettemin kan de buiglijn-cömpensator 11 om fabricagetechnische redenen een in de onbelaste toestand vlakke onderzijde bezitten (fig. 3). Deze yervofmt zich dan in de bedrijfstoestand tot een als het ware lensvormige dwarsdoorsnede.In the exemplary embodiment, these spacer bars 13 are also provided with return springs 14. The pressure plates 12 themselves have the aforementioned lateral flanges 15, so that the hydraulic hoses 7 are, as it were, enclosed in the pressure plates. The return springs 14 also serve these sideways pressing flanges 15 against the underside of the crossbars 5, so that the unit, in particular during transport and assembly, forms a closed unit. The device is designed in such a way that the hydraulic hoses 7 are on-2Q. the deformed state have a round hydraulic cross-section, drawn in dashes and dots in Fig. 4, whose diameter D, as can be seen in Fig. 4, is greater than the aforementioned maximum distance A. Finally, the device is designed in such a way that the hydraulic hoses 7 in the operating condition under the pressing pressure with essentially oval cross-sections on the pressure plate 12 and 12 respectively. are supported on the cross beam 5 with a wide plane. This support can again be provided indirectly or directly. In the exemplary embodiment, the hydraulic hoses 7 in the oval operating position have a cross section, which constitutes about 75% of the undeformed round cross section. For the reasons already explained above, in the exemplary embodiment (but not necessarily a bending line compensator 1.1 is provided, which in the exemplary embodiment is arranged between the hydraulic beams 5 and 35. The hydraulic hoses 7 are not shown. are connected, they are connected to a common pressure medium source .. Incidentally, in the exemplary embodiment, the hydraulic hoses 7 run parallel to the cross beams 5 and 4Q below them.Two hydraulic hoses 7 8103276 -7- • are arranged per cross beam 5. crossbars 5 can run as shown in fig. 1. The hydraulic hoses 7 run underneath these crossbars 5 and bridge the space between adjacent crossbars 5. A special support of the hydraulic hoses 7 in the area between the crossbars 5 is not The pressure plate 5 is simultaneously designed as a heat insulation device or of a d very furnished. A pressure gauge 16 / which is connected to one of the hydraulic hoses 7 with a push-in coupling or the like / serves to check the discharge pressure. In the operating state, the hydraulic hoses 7 are incidentally close to each other / as shown in Fig. 4. The bending line compensator 11 compensates for the deflection, more precisely the bending lines / of the upper crossbars 5 and of the lower crossbars 6. Nevertheless, the bending line compensator 11 can have a flat underside in manufacturing condition (fig. 3). In its operating condition, this yervofmt turns into a lenticular cross-section, as it were.

20 Fig. 5-7 verduidelijken een uitvoerings vorm van de uitvinding/ die zonder drukmiddelbron in de vorm van eèn pomp of dergelijke werkt. Uit een vergelijkende beschouwing van fig. 5,6 is allereerst te zien, dat ook hier de hydraulische slangen 7 onder tussenschakeling van de 25 reeds genoemde buiglijnencondensator 11 aan de dwarsbalken 5,6 en aan de bijbehorende drukplaat 12 ondersteund zijn.FIG. 5-7 illustrate an embodiment of the invention / which operates without a pressure medium source in the form of a pump or the like. From a comparative consideration of Fig. 5,6 it can first be seen that here also the hydraulic hoses 7 are supported on the cross beams 5,6 and on the associated pressure plate 12 under the interposition of the bending line capacitor 11 already mentioned.

Deze compensator compenseert op de reeds toegelichte manier de doorbuigingen van de dwarsbalken 5,6 in de bedrijfstoestand. In fig. 6 is te zien, dat de hydraulische slangen 7 30 bij deze uitvoering vast afgesloten zijn, alleen voor een deel yan hun onveryormde ronde hydraulische slangdwarsdoor-snede (fig. 61 met een incompressibele vloeistof 17 zijn ge-yuld, De spaninrichting 9 van de spanbouten 8 is tegelijk als bedieningsinrichting van de persdrukopwekinrichting uit-35 geyoerd. De spanhouten 8 zijn schroefbouten, waarop met eèn schroefsleutel spanbare moeren 9 als spaninrichting zijn opgezet, waarbij kogellegers, onderlegschijven of andere de wjtrijying yerminderende elementen kunnen zijn aangebracht.This compensator compensates in the manner already explained for the deflections of the crossbars 5,6 in the operating condition. In Fig. 6 it can be seen that the hydraulic hoses 7 in this embodiment are firmly closed, only partly because of their unformed round hydraulic hose cross-section (Fig. 61 with an incompressible liquid 17). The clamping device 9 of the clamping bolts 8 is simultaneously operated as an actuating device of the press-generating device. The clamping woods 8 are threaded bolts, on which tensionable nuts 9 are mounted as a clamping device with a spanner, whereby ball bearings, washers or other displacing elements can be arranged.

De binnenruimten 18 yan de hydraulische slangen 7 mogen met 40 elkaar in communicerende verbinding staan. Daar de hydrau- 81 0 3 2 7 6 * ‘ ' "8“ ’ lische slangen 7 vast afgesloten zijn, zijn ze aan hun einden voorzien van armaturen 19, die dit afsluiten bewerken.The interior spaces 18 of the hydraulic hoses 7 may be in communication with each other. Since the hydraulic 81 0 3 2 7 6 * "" "8" "hoses 7 are tightly closed, they are provided at their ends with fittings 19 which process this sealing.

' ii

Voorzover de hydraulische slangen 7 met elkaar in communicerende verbinding staan, zijn in deze armaturen 19 ook de ka-5 nalen voor de communicerende verbinding aangebracht. De 'opge-brachte persdruk kan men op eenvoudige wijze metend controle-ren, wanneer de reeds beschreven spaninrichtingen 9 bediend worden. Daartoe is aan ten minste ëên van de hydraulische slangen 7 een drukaanwijsinrichting in de vorm van een mano-10 meter 16 of dergelijke aangesloten. Dit geschiedt op doelmatige wijze door middel van een steekkoppeling, zodat de drukaanwij sinrichting 16 bij het transport van de inrichting volgens de uitvinding in totaal van toepassingsplaats tot toepassingsplaats ook afgenomen kan worden. Het uitvoerings-15 voorbeeld is er op gericht, dat de hydraulische slangen 7 evenwijdig aan de dwarsbalken 5,6 en onder de dwarsbalken 5, 6 zijn aangebracht en wel met twee hydraulische slangen 7 per dwarsbalk 5 resp. 6. Men zou echter principieel de hydraulische slangen 7 ook dwars op de dwarsbalken 5,6 kunnen aan-20 brengen. Uit een vergelijkende beschouwing van fig. 6 en 7 is te zien, dat de hydraulische slangen 7 tot ongeveer 75% van hun onvervormde ronde dwarsdoorsneden met de incompressibele vloeistof 27 zijn gevuld. Overigens blijkt uit fig. 7, dat ze in de ^vervormde toestand als het ware dicht tegen elkaar 25 aanliggen, waardoor een zeer gelijkmatige drukverdeling wordt bereikt. Als resultaat is gewaarborgd, dat de hydraulische slangen 7 in alle dwarsdoorsneden onder de bijbehorende dwarsbalken 5,6 en alle hydraulische slangen 7 in de be-drijfstoestand dezelfde vervorming en zodoende dezelfde samen-30 -drukkingondergaan, zodat als resultaat een drukkussen met hydrostatische spanningstoestand met overal gelijke druk functioneert en een gelijkmatige 'en voldoend homogene drukverdeling waarborgt. Een in de hydraulische sLangen 7 aanwezig luchtkussen, dat ten opzichte van de buitenlucht onder 35 oyerdruk. of onderdruk staat, beïnvloedt de beschreven functie niet nadelig.Insofar as the hydraulic hoses 7 are in communicating connection with each other, the channels for the communicating connection are also arranged in these fittings 19. The applied baling pressure can be measured in a simple manner when the clamping devices 9 already described are operated. For this purpose, a pressure indicator in the form of a manometer 10 or the like is connected to at least one of the hydraulic hoses 7. This is expediently effected by means of a plug-in coupling, so that the pressure indicating device 16 can also be removed from application location to application location during the transportation of the device according to the invention. The exemplary embodiment is aimed at the fact that the hydraulic hoses 7 are arranged parallel to the cross beams 5,6 and under the cross beams 5, 6, namely with two hydraulic hoses 7 per cross beam 5 and 6, respectively. 6. In principle, however, the hydraulic hoses 7 could also be arranged transversely of the cross beams 5,6. From a comparative consideration of Figures 6 and 7, it can be seen that the hydraulic hoses 7 are filled with the incompressible fluid 27 to about 75% of their undistorted circular cross sections. Incidentally, it can be seen from Fig. 7 that, in the deformed state, they are as it were close to each other, so that a very uniform pressure distribution is achieved. As a result, it is ensured that the hydraulic hoses 7 in all cross sections under the associated crossbars 5,6 and all hydraulic hoses 7 in the operating state undergo the same deformation and thus the same compression, so that as a result a pressure pad with hydrostatic tension state with equal pressure functions everywhere and ensures a uniform and sufficiently homogeneous pressure distribution. An air cushion present in the hydraulic hoses 7, which is under oxygen pressure relative to the outside air. or underpressure does not affect the described function.

Zowel bij de uitvoeringsvorm van fig. 1-4 als bij die van fig. 5 en 7 kan de buiglijncompensator 21 ook ontbreken, 8103276The bending line compensator 21 may also be missing in the embodiment of Figs. 1-4 as well as in that of Figs. 5 and 7, 8103276
