Laite radan tukikerroksen poistamiseksi raidetta purkamat-taDevice for removing the track support layer without disassembling the track
Keksintd koskee patenttivaatimuksen 1 johdanto-osan mu-kaista laitetta radan tukikerroksen poistamiseksi raidetta 5 purkamatta.The invention relates to a device according to the preamble of claim 1 for removing a track support layer without dismantling the track 5.
Radan rakenteelliset osat ovat raide, joka kåsittåå kiskot ja ratapdlkyt, raiteen tukikerros, vålikerros, eristysker-ros ja pengertåyte. Tukikerroksen tehtåvå on pysyttåå raide sille mååritellysså, geometrisesti oikeassa asennos-10 sa ja raiteen tukemisen pååmåårånå on aikaansaada raide, joka on sekå korkeus- ettå sivusuunnassa tarkoin oikeassa asennossa.The structural parts of the track are the track, which consists of rails and track gauges, the track support layer, the intermediate layer, the insulation layer and the embankment infill. The purpose of the support layer is to maintain the track in the geometrically correct position defined for it, and the purpose of supporting the track is to provide a track that is in exactly the correct position in both height and lateral direction.
Tukikerros valmistetaan nykyåån raidesepelistå. Sepelin valmistukseen kaytettåvan kiviaineksen tulee olla mahdol-15 lisimman lujaa, rapautumatonta, kulutusta ja iskuja kestå-våå kivilajia. Raidesepeli ei saa sisåltåå multaa, kasvin-jåtteitå eikå muitakaan epapuhtauksia, jotka saattaisivat edesauttaa routimista.Today, the support layer is made of rail play. The aggregate used to make the crushed stone must be the strongest, non-weathering, abrasion and impact resistant stone type possible. The rail game must not contain mold, plant debris or other contaminants that could contribute to frostbite.
Vaikka tukikerroksen laatuvaatimukset ovat hyvin korkeat, 20 on selvåå, ettå ajan myotå raidesepelin rapautumisen ja likaantumisen seurauksena tukikerroksessa tapahtuu muodon-muutoksia, jolloin radan geometria muuttuu. Tukikerroksessa olevat epåpuhtaudet aikaansaavat jååtyessåån routa-nousuja rataan. Erityisen herkkiå routavaurioiden synty-25 miselle ovat esimerkiksi tasoristeykset, jolloin maan- tieliikenteen mukanaan kuljettama multa ja muut routivat aineosat pilaavat raidesepelin. Tålloin radan tukikerros on purettava ja tukemistyo tehtåvå uudelleen raiteen oikeaan asentoon saattamiseksi.Although the quality requirements for the support layer are very high, it is clear that over time, as a result of weathering and soiling of the rail play, deformations take place in the support layer, whereby the geometry of the track changes. Contaminants in the support layer cause frost rises on the track when it freezes. Level crossings, for example, are particularly sensitive to frost damage, in which case the soil and other frosting components carried by road traffic damage the railroad game. In this case, the track support layer must be dismantled and the support work performed again to bring the track to the correct position.
30 Jotta raiteen tukemistyo voitaisiin tehdå uudelleen, on koko vanha tukikerros poistettava ja puhdistettava seu- 2 92621 lomalla uudelleenkåyttdå vårten. Mikåli raidesepeli on huonokuntoista, se kåytetåån mieluimmin penkereen vahvis-tustoisså tai kuljetetaan kokonaan pois. Jos vanha raidesepeli on tarkoitus kåyttåå pengerrystoissa olisi eduk-5 si, ettå sepeli tukikerrosta purettaessa voitaisiin si-joittaa molemmille puolille rataa, josta se olisi helppo saada uudelleen kåyttdon.30 In order to be able to re-support the track, the entire old support layer must be removed and cleaned after re-use. If the rail game is in poor condition, it is preferably used in embankment reinforcements or transported away completely. If the old railroad game is to be used in embankments, it would be advantageous that the crushed stone, when dismantling the support layer, could be placed on both sides of the track, from where it would be easy to get it used again.
Raidesepelin vaihtaminen uuteen suoritetaan yleenså siten, ettå raide ensiksi puretaan ja siirretåån syrjåån, minkå 10 jålkeen vanha tukikerros ja mahdollisesti myos muita radan rakennekerroksia voidaan uusia. Tunnetaan myos laite, jonka avulla raidesepeli voidaan poistaa raidetta purka-matta. Tållaisessa laitteessa raiteen alta kulkee kaavin-ketju, joka kaapii tukikerroksen kiviaineksen ja kuljettaa 15 sen laitteistossa olevalle seulalle. Seulan avulla kivi-aineksesta erotetaan sepeli ja jåteaines. Sepeli kuljetetaan takaisin raiteen alle ja jåteaines kuljetetaan hihna-kuljettimella radan toiseen sivuun. Kaavinketjussa olevat kauhat kåsittåvåt tyypillisesti kovateråksestå valmistet-20 tuja sormimaisia elimiå, jotka irrottavat kiviaineksen tukikerroksesta. Laitteistoon kuuluva seula on tyypillisesti tåryseula.The replacement of the track game with a new one is usually carried out in such a way that the track is first dismantled and moved aside, after which the old support layer and possibly also other structural layers of the track can be renewed. A device is also known by means of which a track game can be removed without dismantling the track. In such a device, a scraper chain passes under the track, which scrapes the rock material of the support layer and transports it to a screen in the equipment. The sieve is used to separate crushed stone and waste material from the aggregate. The crushed stone is transported back under the track and the waste material is transported by a belt conveyor to the other side of the track. The buckets in the scraper chain typically comprise finger-like members made of hard steel that detach the aggregate from the support layer. The screen included in the apparatus is typically a screen.
Oleellista tållaisessa tunnetun tekniikan mukaisessa laitteessa on se, ettå kaavinketju ja siihen kuuluvat 25 ohjainelimet muodostavat suljetun kokonaisuuden, joka kulkee raiteen alta. Laitteisto on sijoitettu radalla kulkevan alustan påålle ja siihen on tavallisesti raken-nettu my6s raiteen kannatuselimet. Kyseinen laite on alku-jaan suunniteltu sepelinpuhdistuskoneeksi.What is essential in such a prior art device is that the scraper chain and its associated guide members form a closed entity which runs under the track. The equipment is placed on a track running on the track and is usually also built with track support members. This device was originally designed as a crown cleaning machine.
30 Tunnetun tekniikan mukaisen laitteen toiminnassa on useita epåkohtia. Kaavinketjun asettamiseksi paikalleen on raiteen alle kaivettava radan poikkisuunnassa ulottuva kai-vanto, johon kaavinketjun irrotettu ensimmåinen påå asete-taan ja kiinnitetåån ketjun toiseen pååhån raiteen alitse 3 92621 kulkevaksi pååttymåttdmåksi elimeksi. Kaivarvto joudutaan yleenså tekemåån kåsin. Jos poistettava materiaali halu-taan kåyttåå esimerkiksi pengerrystoihin, siirtåå tunnettu laite koko poistettavan materiaalin yhdelle puolelle 5 rataa. Tåstå se on sitten siirrettåvå erikseen tasaisesti radan molemmille puolille. Junien ohitusten ajaksi laite on siirrettåvå sivuraiteelle, jolloin kuljetusmatkat saattavat muodostua hyvinkin pitkiksi, mikå luonnollisesti viivyttåå tyon valmistumista. Laitteen hankintahinta on 10 erittåin korkea, minkå vuoksi pååomakustannusten merkitys korostuu koneen alkuperåisiin toimintoihin nåhden vaati-mattomassa raidesepelin vaihtotyosså. Raidesepelin vaihto-tyo tulisi pystyå suorittamaan paljon kevyemmån ja huomat-tavasti halvemman laitteiston avulla.30 There are several drawbacks to the operation of the prior art device. To place the scraper chain in place, a trench extending transversely to the track must be excavated under the track, into which the removed first end of the scraper chain is placed and fastened to the other end of the chain as an endless member running under the track 3 92621. The engraving usually has to be done by hand. If the material to be removed is to be used, for example, in embankments, the known device transfers the entire material to be removed to one side of the track 5. From here it must then be moved separately evenly on both sides of the track. During the passing of trains, the device has to be moved to the siding, which means that the transport distances can be very long, which naturally delays the completion of the work. The purchase price of the device is very high, which is why the importance of capital costs is emphasized in the modest rail game replacement work compared to the original functions of the machine. The replacement of the rail game should be able to be performed with much lighter and considerably cheaper equipment.
15 Keksinndn tavoitteena on poistaa edellåmainitut epåkohdat ja esittåå rakenteeltaan yksinkertainen ja toiminnaltaan joustava laite radan tukikerroksen poistamiseksi raidetta purkamatta. Nåmå tavoitteet saavutetaan keksinndn mukaisen laitteen avulla, joka on tunnettu siitå, mitå on esitetty 20 patenttivaatimuksen 1 tunnusmerkkiosassa. Laitetta kåyte-tåån sellaisen pydrå- tai telarakenteisen kaivinkoneen avulla, joka on varustettu lisåksi teråksisillå ratapyd-rillå radalla liikkumista vårten. Tåstå on se etu, ettå laitteisto voidaan kuljettaa rakennuspaikalle maanteitse 25 ja ettå junien ohitusten ajaksi laitteistoa ei tarvitse siirtåå radalla pitkiå matkoja, vaan voidaan kåyttåå esimerkiksi låhintå tasoliittymåå, misså kaivinkone aje-taan syrjåån junien ohitusten ajaksi. Kaivinkoneen puomiin kiinnitetty keksinndn mukainen laite tyonnetåån mainittua 30 puomia kåyttåen tukikerrokseen raiteen alle radan sivulta. Laite voidaan tyontåå raiteen alle ilman erillisiå kaivan-toja ja sen avulla pystytåån purkamaan tukikerrosta tasaisesti radan molemmille puolille. Eråån suoritusmuodon mukaisessa laitteessa on alaosastaan leveåmmåt, lapamaiset 35 siirtoelimet, jotka siirtåvåt sepelin varovasti liu'utta-malla syrjåån, jolloin ratapdlkyt eivåt rikkoudu.The object of the invention is to eliminate the aforementioned drawbacks and to provide a device with a simple structure and a flexible function for removing the track support layer without dismantling the track. These objects are achieved by means of a device according to the invention, which is characterized by what is stated in the characterizing part of claim 1. The device is operated by means of a hydraulic or crawler excavator which is additionally equipped with a steel rail roller for movement on the track. This has the advantage that the equipment can be transported to the construction site by road 25 and that during the train overtaking the equipment does not have to be moved on the track for long distances, but can be used, for example, at the nearest level crossing where the excavator is driven aside during train overtaking. The device according to the invention attached to the boom of an excavator is pushed into said support layer below the track from the side of the track using said boom. The device can be pushed under the track without separate ditches and can be used to unload the support layer evenly on both sides of the track. In one embodiment, the device has wider, blade-like transfer members 35 at the bottom, which gently move the crushed stone aside, so that the track slots are not broken.

KeksinnOn mukaisen laitteen avulla saavutetaan myOs huo-mattava ajallinen sååsto. Esimerkiksi yksiraiteisen taso-liittymån kohdalla tukikerroksen vaihtamiseen kuluu aikaa vain noin 2-3 tuntia. Radalla tyoskentelynopeus on n. 100 5 rata-m/h ja tydn tekemiseen tarvitaan vain muutama henki lo. Kaivinkoneen yhteyteen voidaan tarvittaessa liittåå seulakauha, jolloin voidaan suorittaa yhtajaksoisesti kaikki ne tyovaiheet mitkå tukikerroksen parantaminen vaatii.With the device according to the invention, considerable time savings are also achieved with myOs. For example, in the case of a single-track level interface, it only takes about 2-3 hours to change the support layer. The working speed on the track is approx. 100 5 track m / h and only a few people are needed to complete it. If necessary, a screen bucket can be connected to the excavator, in which case all the work steps required to improve the support layer can be performed simultaneously.
10 Keksintdå selostetaan nyt seuraavassa viittaamalla ohei-siin piirustuksiin, joissa kuva 1 esittåå laitetta asennettuna kaivinkoneeseen ylaviistosta katsottuna ja laitetta raiteen alle tyonnettåesså, 15 kuva 2 esittåå kuvan 1 mukaista laitetta asennettuna kaivinkoneeseen ylhååltå katsottuna, kuva 3 esitt&a keksinndn mukaista laitetta ylhååltå katsottuna, kuva 4 esittåå kuvan 3 mukaisen laitteen osakuvaa 20 sivulta katsottuna, kuva 5 esittMå kuvan 3 mukaista laitetta leikkausku- vana kehamåinen elin poistettuna sivulta katsottuna ja kuva 6 esittåå laitetta raiteen alle vietyna.The invention will now be described with reference to the accompanying drawings, in which Figure 1 shows a device mounted on an excavator seen from above and the device is pushed under a rail; Fig. 5 shows a partial view of the device according to Fig. 3 seen from the side, Fig. 5 shows a sectional view of the device according to Fig. 3, the circumferential member removed from the side, and Fig. 6 shows the device under the track.
25 Keksinnon mukaisen laitteen, josta jåljempånå kåytetåån nimitysta sepelinpoistolaite, kåyttdyksikkonå voidaan kåyttaa toiminnoiltaan tavanomaista pydrå- tai telaraken-teista kaivinkonetta tai muuta vastaavaa tyokonetta.The operating unit of the device according to the invention, hereinafter referred to as a debris removal device, can be an excavator with a conventional hydraulic or roller structure or other similar working machine.
Kåytetty kaivinkone poikkeaa tavanomaisista kaivinkoneista 30 vain siinå, ettå se on varustettu teråsrakenteisilla rata-pyorilla radalla liikkumista vårten. Varsinainen sepelinpoistolaite kiinnitetSån kaivinkoneen puomissa olevaan pikakiinnityspaikkaan. Tåhån pikakiinnityspaikkaan voidaan purkutydn tultua suoritetuksi kiinnittSå myos esimerkiksi 92621 5 seulakauha, jonka avulla raiteen alta poistettu sepeli puhdistetaan ja seulotaan uudelleenkåyttdå vårten.The excavator used differs from conventional excavators 30 only in that it is equipped with a steel-structured track-wheel for track movement. The actual debris remover attaches to the quick attachment point on the excavator's boom. After the demolition has been completed, a sieve bucket, for example 92621 5, can also be attached to this quick-attachment point, by means of which the crushed stone removed from under the track is cleaned and screened for reuse.
Sepelinpoistolaitteen liikeratojen suhteen ovat kåytosså kaikki kaivinkoneessa muutoinkin olevat liikeradat. Sitå 5 voidaan siten siirtåå ylds- ja alaspain, eteen- ja taakse-påin, vasemmalle ja oikealle ja sita voidaan kallistaa ja pyorittåa puomin paassa.With regard to the trajectories of the gravel removal device, all the trajectories otherwise present in the excavator are in use. It 5 can thus be moved up and down, forwards and backwards, left and right and can be tilted and rotated in the boom head.
Sepelinpoistolaite saa kåyttdvoiman kaivinkoneen hydrau-liikkajårjestelmasta. Toimilaitteena 7 toimivan hydrauli-10 moottorin letkut kytketaan kaivinkoneen vastaaviin hyd-rauliikkaliittimiin ts. hydrauliikan tulo- ja paluulet-kuun, minka jaikeen hydraulimoottorin toimintaa voidaan ohjata venttiililia kaivinkoneen ohjaamosta. Kun hydraulimoottorin pydrimissuuntaa halutaan muuttaa, muutetaan 15 hydraulinesteen virtauksen suuntaa siten, etta tuloletku muuttuu paluuletkuksi ja vastaavasti paluuletku tulolet-kuksi.The crusher is powered by the excavator's hydraulic motion system. The hoses of the hydraulic-10 motor acting as the actuator 7 are connected to the corresponding hydraulic connectors of the excavator, i.e. to the hydraulic inlet and return hoses, by which the operation of the hydraulic motor can be controlled by a valve from the excavator cab. When it is desired to change the direction of rotation of the hydraulic motor, the direction of flow of the hydraulic fluid is changed so that the inlet hose becomes a return hose and the return hose becomes an inlet hose, respectively.
Sepelinpoistolaite kasittåå paapiirteittain tarkasteltuna runko-osan 1 ja runko-osaan 1 yhteydesså olevan kehåmåisen 20 paåttymattGmån elimen 2, johon on kiinnitetty siirtoelimia 3. Runko-osa 1 on oleellisesti tasomainen lapa tai vastaa-va, joka on tarkoitettu sijoitettavaksi raiteen alle oleellisesti vaakasuuntaisesti. Kuten jo edelia mainit-tiin, raiteella tarkoitetaan tåssM ratapGlkkyjå ja niihin 25 kiinnitettyja kiskoja. Kehamainen paattymaton elin 2 on sijoitettu runko-osan 1 ulkokehaile. Sepelinpoistolaite tydnnetåån tukikerrokseen radan sivulta oleellisesti vaakatasossa. Paattymattdmaan kehamaiseen elimeen 2 kiin-nitetyt siirtoelimet 3 kaivautuvat tukikerroksen kivi-30 ainekseen ja siirtavat sen raiteen alta mainitulle radan ‘ sivulle. Sepelinpoistolaite siirtåå tukikerroksen kiviai- nesta raiteen keskialueelta radan reunaan, minka jålkeen laite kåånnetåån tydskentelemåån vastaavalla tavalla radan toiselle puolelle.The crushed stone removal device comprises a body part 1 and a circumferential endless member 2 in connection with the body part 1, to which the transfer members 3 are attached, viewed from the side, the body part 1 being a substantially planar blade or the like intended to be placed substantially horizontally under the track. As already mentioned above, track means tåssM track gauges and rails attached to them. A circumferential endless member 2 is placed on the outer frame of the body part 1. The crushed stone removal device is filled into the support layer from the side of the track in a substantially horizontal plane. The transfer members 3 attached to the endless circumferential member 2 dig into the rock-30 material of the support layer and transfer it below the track to said 'side' of the track. The crushed stone removal device moves the support layer from the rocky area of the track to the edge of the track, after which the device is turned to the other side of the track in a corresponding manner.

KehSmåinen påSttymåtOn elin 2 on esimerkkitapauksessa telaketju tai vastaava ja siirtoelin 3 on kehåmåisestå elimestå 2 oleellisesti kohtisuorassa ulkoneva, pystysuo-rassa suunnassa ulottuva lapa. Kehåmåiseen elimeen 2, 5 siirtoelimien 3 våliin, on lisåksi kiinnitetty kovametal-lista valmistettuja sormimaisia elimiå 4, jotka on tarkoi-tettu irrottaraaan tukikerroksessa mahdollisesti olevaa jååtå tai hyvin tiiviiksi tiivistynyttå kiviainesta.The circumferential endless member 2 is, by way of example, a track or the like, and the transfer member 3 is a blade extending substantially perpendicular to the circumferential member 2 and extending in a vertical direction. In addition, finger-like members 4 made of carbide are fastened to the circumferential member 2, 5 between the transfer members 3, which are intended to remove any ice or very tightly compacted rock material in the support layer.
Siirtoelin 3 on alaosastaan 3' oleellisesti leveåmpi kuin 10 ylåosastaan 3''. TSmå mahdollistaa siirtoelimen 3 kai- vautumisen kiviainekseen siten, ettS kehåmåisen elimen 2 pydrimisliikkeen aikana siirtoelimen alaosan 3' ylåpuolel-la oleva tukikerroksen kiviaines vajoaa ensin alaspåin, minks jålkeen se siirtyy siirtoelimen 3 tyontamana radan 15 sivuun. Siirtoelimet 3 siirtåvåt kiviainesta tukikerrok-sesta siten, ettS tukikerros vajoaa kaytetylle kiviainek-selle ominaista liukupintaa pitkin viipaleina siirtoelimen 3 kuljetettavaksi. PyOrivå telaketju ei siten pSSse vauri-oittamaan raiderakenteita.The transfer member 3 is substantially wider at its lower part 3 'than at its upper part 3' '. TSmå allows the transfer member 3 to be excavated in the aggregate so that during the pyridization movement of the circumferential member 2, the aggregate of the support layer above the lower part 3 'of the transfer member first sinks downwards, after which it moves to the side of the track 15. The transfer members 3 transfer the aggregate from the support layer so that the support layer sinks along the sliding surface characteristic of the aggregate used in slices for transport by the transfer member 3. The PyOrivå track does not pSSse damage the track structures.
20 KehSmSinen elin 2 on jarjestetty pyOrimSSn laitteen runko-osaan 1 laakeroidun pyOrSn 5 ohjaamana, jolloin mainittu pyOrS 5 on yhteydessa toimilaitteeseen 7 edullisesti voimanvalityselimiston 8 vålityksellS. Toimilaitteena 7 toimii esimerkkitapauksessa hydraulimoottori, kuten edella 25 jo mainittiin. VoimanvålityselimistO 8 kasittaå planeet-tapyOrastGn, joka on jarjestetty sSStamSSn kehamåisen elimen 2 pyOrimisnopeutta. Planeettapy5raston pyorien vSlityssuhde on valittu sellaiseksi, ettS kehåmaisen elimen 2 ts. telaketjun pyOrimisnopeutta voidaan muuttaa 30 sopivien raja-arvojen rajoissa.The frame member 2 is arranged under the control of a wheel 5 mounted on the body 1 of the rotating device, said wheel 5 being in communication with the actuator 7, preferably via a power selector 8. In the exemplary case, the actuator 7 is a hydraulic motor, as already mentioned above. THE TRANSMISSION SYSTEM 8 handles a planetary pin that is arranged to adjust the rotational speed of the circumferential member 2. The gear ratio of the planets of the planetary gear has been chosen such that the rotational speed of the circumferential member 2, i.e. the track, can be varied within the limits of the suitable limits.
KehSmSisen elimen 2 liikerata on pitkånomainen. Tamå on aikaansaatu siten, ettS kehåmåinen elin 2 on jarjestetty pyorimåån lisåksi toisen runko-osaan 1 laakeroidun pyOrån 6 ohjaamana. Py5rå 6 on laakeroitu jousikuormitteiseen • · * 92621 7 hahloon 10, joka hahlo 10 on ylikuormitustilanteessa jår-jestetty siirtymåån runko-osaan 1 kiinnitettyjen, laitteen pituussuuntaisten liikeohjainten 11 ohjaamana kohti toimi-laitteeseen 7 yhteydesså olevaa pyoråå 5. Toinen pyorå 6 5 on siis jousikuormitteinen, jolloin se on tuettu runko- osaan 1 jousielimen 12 vålityksellå. Tåstå on se etu, ettå esimerkiksi kiven joutuessa telaketjun ja pyorån 6 tai pydrån 5 våliin laitteisto ei pååse rikkoutumaan. Esimerk-kitapauksessa jousielin 12 on kierrejousi.The trajectory of the frame member 2 is elongated. This is achieved in that the circumferential member 2 is arranged to rotate in addition to the second frame part 1 under the control of a wheel 6 mounted on it. The wheel 6 is mounted in a spring-loaded slot 10 which, in the event of an overload, is arranged to move towards the actuator 7. The wheel 5 is connected to the actuator 7 under the control of the longitudinal motion guides 11 attached to the body part 1. , wherein it is supported on the body part 1 by means of a spring member 12. This has the advantage that, for example, if the stone gets between the track and the wheel 6 or the wheel 5, the equipment cannot break. In the exemplary case, the spring member 12 is a coil spring.
10 Laitteen runko-osaan 1 on jårjestetty lisåksi ripustuseli-met 9, jotka sijaitsevat edullisesti låhempånå toimilait-teeseen 7 yhteydesså olevaa pydråa 5, erillåån mainitusta toimilaitteesta 7.The body part 1 of the device is further provided with suspension members 9, which are preferably located closer to the hydrator 5 in connection with the actuator 7, separately from said actuator 7.
Laite toimii seuraavasti. Hydraulimoottori pydrittåå 15 planeettapyoråstdå, josta voima siirretåån vetopyorålle ja siitå edelleen telaketjulle, joka suorittaa tukikerroksen poistamisen raiteen alta siirtoelimien avulla. Telaketju kååntyy taittopydrån ympåri ja siitå takaisin vetopyorålle. Taittopyorå on jousikuormitteinen ja se pååsee siirty-20 måån vetopydråå 5 kohden hahlossa 10. Laitteisto on suo-jattu telaketjun molemmille puolille ts. sen ylå- ja alapuolelle asetetuilla runko-osaan kuuluvilla suojale-vyillå. Siirryttåesså tydskentelemåån radan toiselle puo-lelle hydrauliikkaventtiililla muutetaan telan pyorimis-25 suuntaa niin, ettå kiviaines siirtyy radan alta ulospfiin.The device works as follows. The hydraulic motor pulls on 15 planetary gears, from which the power is transferred to the traction wheel and from there to the track, which performs the removal of the support layer from under the track by means of transfer members. The track turns around the folding wheel and then back to the traction sheave. The folding wheel is spring-loaded and can move towards the drawbar 5 in the slot 10. The apparatus is protected on both sides of the track, i.e. by protective plates belonging to the frame part placed above and below it. When moving to the other side of the track to be filled with a hydraulic valve, the direction of rotation of the roll is changed so that the aggregate is transferred from below the track to the outlet.
Keksinto ei ole rajoitettu edellå esitettyyn suoritusmuo-toon, vaan sitå voidaan muunnella oheisten patenttivaati-musten puitteissa. Laitteen ei vålttåmåttå tarvitse olla pitkånomainen ja varustettu kahden pyorån ympåri kierty-30 vållå telaketjulla, vaan se voidaan muotoilla muunkin muotoiseksi.The invention is not limited to the embodiment described above, but can be modified within the scope of the appended claims. The device does not necessarily have to be elongated and equipped with a tracked chain around two wheels, but can be shaped to another shape.
