Sovitelma betoninkuljetussekoittimen yhteydessåArrangement in connection with a concrete transport mixer
Keksinnon kohteena on patenttivaatimuksen 1 johdannossa IShemmin mMSritelty sovitelma pumpun ja siirtolaitteen 5 kiinnittSmisksi erityisesti betoninkuljetussekoittimen, kuten kuorma-auton alustalle tai vastaavalle sijoitetun pyorintSsMilion yhteyteen.The invention relates to an arrangement for attaching a pump and a conveying device 5, as defined in the preamble of claim 1, in particular in connection with a rotary conveyor placed on a concrete transport mixer, such as a truck chassis or the like.
Betonin kuljetus ja sen jatkokasittely tyomaalla 10 tapahtuu kSytannossa siten, etta betoni kuljetetaan pySrintSsSiliollS varustetulla ajoneuvolla tyokoh-teeseen, jossa betoni siirretåån edelleen kåyttokoh-teeseensa usein ajoneuvon muiden apulaitteiden avulla. Kuljetukseen kSytettSvS ajoneuvo kasittSM talloin 15 pydrintåsSilion ja taytto-/tyhjennyssuppilon lisaksi yleensS yhdesta tai useammasta vakiopituisesta osasta koostuvan valukourun, jolla betoni siirretåån pydrinta-sailiostS pyorintasailion alapuolella sijaitsevaan betonin vastaanottokohteeseen. MikSli vastaanottokohde 20 sijaitsee pydrintSsåilidn ylapuolella, on betonin kuljettamiseksi ja siirtåmiseksi edelleen kayttokoh-teeseensa edul lista kayttciei ns. pumppuautoa, jolla tarkoitetaan pumpulla ja puomistolla varustettua betoninkuljetussekoitinta. Pumpun ja puomiston yh-25 teydessa olevan putkiston avulla tapahtuu betonin « ’ siirto tydmaalla kSyttokohteeseensa vaivattomasti verrattuna tavanomaisiin hihnakuljetin- ym. ratkaisui-hin puomiston hyvån ulottuvuuden vuoksi.The transport of the concrete and its further processing on site 10 takes place in such a way that the concrete is transported by a vehicle equipped with a rotary silo to the work site, where the concrete is often transferred to its place of use by means of other auxiliary devices of the vehicle. In addition to the 15 slurrying silos and the filling / emptying funnel, the vehicle used for transport is usually a pouring trough consisting of one or more constant-length parts, with which the concrete is transferred from the slurry tank to the concrete receiving space below the slurry tank. As the receiving site 20 is located above the hydrothora, it is advantageous to use concrete for transporting and transferring the concrete to its destination. a pump truck, which means a concrete transport mixer with a pump and a boom. With the help of the piping connected to the pump and the boom, the concrete is transferred to its destination easily compared to conventional conveyor and other solutions due to the good reach of the boom.
30 Pohjoismaissa, IShinnM liikennelupajarjestelyista ja betonin kuljetusta harjoittavien yritysten pienesta koosta johtuen, on yleistS, etta yrittajat hankkivat kayttotarkoituksiinsa sopivan betoninkuljetussekoittimen sekå siihen liitettavat osat, kuten ajoneuvon 35 alustan, pyorintSsailion varusteineen, pumpun, puomiston, kåyttojSrjestelmSn (kuten hydrauliikan) ym. er i laitetoimittajilta, jotka osat kootaan yleensa yrit-tMjMn kotimaassa yrittSjån tarpeiden mukaiseksi 91550 2 toimivaksi kokonaisuudeksi. Muualla maailmassa on yleistå, etta betoninkuljetussekoittimet hankitaan valmiina, eri merkkisille ajoneuvoalustoille koottuina kokonaisuuksina.30 In the Nordic countries, due to traffic licensing arrangements and the small size of concrete transport companies, it is common for operators to obtain a concrete mixer and associated parts for their application, such as a vehicle 35 chassis, a hydraulic system with equipment, a pump, a boom, a boom. , which are usually assembled into a 91550 2 functional entity that meets the needs of the entrepreneur in Finland. Elsewhere in the world, it is common for concrete mixers to be procured as complete units assembled for different makes of vehicle chassis.

Periaatteena em. erilaisista betonin kuljetusajoneuvo-jen hankintatavoista huolimatta on, ettå betoninkul-jetussekoittimet ovat kokoonpanovaiheensa jålkeen kompakteja kokonaisuuksia, jolloin niiden varustelua 10 ei kåytånnosså oleellisesti muuteta erilaisia kåytto-tarkoituksia vårten. Eri tyyppisille tyotehtåville on olemassa juuri tarkoitusta vårten varustetut ajoneuvot.The principle, despite the above-mentioned different ways of procuring concrete transport vehicles, is that the concrete transport mixers are compact units after their assembly phase, in which case their equipment 10 is not substantially altered in practice for different uses. There are purpose-built vehicles for different types of work.
TastS syysta varsinkin Suomessa, mutta myos muissakin pohjoismaissa, missa yrittajien betoninkuljetuskaluston 15 måårå on suhteellisen niukka, esim. tavalliseen betoninkuljetukseen joudutaan kayttamaan tarpeettoman varusteltuja ajoneuvoja, koska kallista kalustoa ei yleensa ole varaa seisottaa. Tasta onkin seurauksena, etta varsinaisen pumppauskaluston kokonaismaåra 20 tietyissa osissa Suomea ei vastaa kokonaistarvetta, jolloin joudutaan turvautumaan tarpeettoman tehottomiin perinteisiin, jopa manuaalisiin betoninkMsittelyjar-jestelyihin. Nykyinen tilanne saattaa myos varsinkin nailia alueilla vaaristaa oleellisesti kul jetuskaluston 25 kayton hinnoittelua, jolloin pumppauskaluston kåytto on tilaajalle suhteettoman kallista.For this reason, especially in Finland, but also in other Nordic countries, where the number of concrete transport equipment for entrepreneurs is relatively scarce, eg unnecessarily equipped vehicles have to be used for ordinary concrete transport, because expensive equipment cannot usually be stopped. As a result, the total volume of the actual pumping equipment 20 in certain parts of Finland does not meet the total need, which means that unnecessarily inefficient traditional, even manual, concrete treatment arrangements have to be resorted to. The current situation may also significantly jeopardize the pricing of the use of the transport equipment 25, especially in the nylon areas, making the use of the pumping equipment disproportionately expensive for the subscriber.
Alalla vallitsevan tekniikan suhteen viitataan julkai-suun DE-1905051, joka kåsittåå siirreltSvSn betonipump-30 puaseman. Betonipumppuasemassa on hydraulitoiminen apulaite, jonka avulla pumppuasema on nostettavissa ajoneuvon perassa vedettSvalle vaakasuoralle alustalle.With regard to the state of the art, reference is made to DE-1905051, which comprises a mobile concrete pump-30 station. The concrete pumping station has a hydraulically operated auxiliary device, by means of which the pumping station can be lifted onto a horizontal platform towed by the vehicle in Pera.
Nain olien pumppuasemaa ei kiinnitetå betoninkuljetus-sekoittimeen, vaan minka tahansa vetokoukulla varus-35 tetun ajoneuvon yhteyteen, jolloin ko. ratkaisussa on voimassa juuri edella esitetyt epMkohdat.Thus, the pumping station is not attached to the concrete transport mixer, but to any vehicle equipped with a towbar, in which case the The solution is based on the points outlined above.

Toinen tekniikan tasoon liittyvå julkaisu DE-2812031 kåsittåå tavanomaisen betoninkul jetussekoittimen, jossa sekoittimen poistoaukon alapuolelle on sijoitettu 5 vSlisMilio seko i tt lines ta poistettavan materiaalin måårMn kontrolloimiseksi. Julkaisussa on esltetty myos yhtenå vaihtoehtona sekoittimen alle sijoitetun sailion yhteyteen jarjestetty pumppu ja siirtolaite, jotka on kiinnitetty ajoneuvon runkoon. Julkaisussa ei kuiten-10 kaan ole esitetty, etta pumppu ja siirtolaite olisivat samaan vålirunkoon yhdesså sijoitettuina irrotetta-vasti kiinnitettMvissa ajoneuvoon. Nåin olien julkaisussa esitetty betoninkuljetussekoitin on kokoon-panovaiheensa jalkeen kompakti kokonaisuus, jolloin 15 ajoneuvon varustelua kaytSnnossS ei ole tarkoituksena muuttaa erilaisia kayttotarkoituksia vårten.Another prior art publication DE-2812031 comprises a conventional concrete transport mixer in which 5 vSlisMilio mixing lines are placed below the outlet of the mixer to control the amount of material to be removed. The publication also discloses, as an alternative, a pump and a transfer device arranged in connection with a silo placed under the agitator and attached to the body of the vehicle. However, the publication does not disclose that the pump and the transfer device are detachably attached to the vehicle in the same intermediate frame. Thus, the concrete transport mixer presented in the publication is a compact unit after its assembly step, in which case the equipment of 15 vehicles is not intended to be changed for different uses.
LisSksi voidaan vielS viitata julkaisuun SE-333449, joka kåsittSå menetelmSn ja laitteiston, jolla on 20 mahdollista kiinnittaå ajoneuvon peråSn irrotettavasti erilaisia apuvSlineitS pystysuunnassa toimivien tukielimien avulla. Julkaisussa esitetty ratkaisu ei ole kuitenkaan tarkoitettu kaytettavaksi betoninkul-jetussekoittimen yhteydesså siten, etta betoninkul-25 jetussekoittimen peråSn kiinnitettaisiin valirungossa olevat pumppu ja siirtolaite.In addition, reference may be made to SE-333449, which discloses a method and apparatus for detachably attaching various accessories to the rear of a vehicle by means of vertically operating support members. However, the solution presented in the publication is not intended to be used in connection with a concrete conveyor mixer, so that the pump and transfer device in the casting frame are attached to the rear of the concrete conveyor mixer.

* Hydraulitoiminen pumppu on kytkettSvisså betoninkul- j etussekoittimen hydrauliikkaj arj estelmaan.* The hydraulically operated pump is connected to the hydraulic system of the concrete mixer.
35 Vielå voitaneen viitata julkaisuun DE-3006682, jossa esitetysså konstruktiossa on kåytetty ruuvikuljetinta, mikå on epåedullista, koska ruuvikuljettimen pituutta ei ole mahdollista sååtåå. Ruuvikuljetinta voidaan 4 91550 betoninjakelun yhteydesså ainoastaan kallistaa erilai-siin asentoihin.Reference may also be made to DE-3006682, in which a screw conveyor is used in the construction shown, which is disadvantageous because it is not possible to adjust the length of the screw conveyor. The screw conveyor can only be tilted to different positions during 4 91550 concrete distribution.
