Description

Uprawniony z patentu: Friedrich Schwing, Wanne Eickel (Republika Fe¬ deralna Niemiec) Pompa do betonu z dwoma cylindrami i wspólnym otworem wylotowym Przedmiotem wynalazku jest pompa do betonu z dwoma cylindrami i wspólnym otworem wylo¬ towym.Znane sa pompy do betonu, które posiadaja róz¬ norodne systemy sterowania, przy czym najbar¬ dziej rozpowszechnione sa pompy z plaskimi su¬ wakami wykonujacymi ruch posuwisto-zwrotny za pomoca mimosrodu polaczonego z mechanizmem tloka, dzieki czemu nastepuje otwieranie i zamy¬ kanie kanalów sterowniczych do cylindra pompy.Takie rozwiazanie konstrukcji pompy posiada pewna wade, która charakteryzuje sie zbyt szyb¬ kim zuzyciem plaszczyzn suwaka i powstawaniem nieszczelnosci miedzy suwakiem i plaszczyzna sliz¬ gowa, po której przesuwa sie suwak oraz miedzy drazkami wodzacymi suwak a dlawnicami uszczel¬ niajacymi. Uszczelnienie drazków staje sie z cza¬ sem coraz bardziej utrudnione ze wzgledu na to, ze traca one swój okragly ksztalt i staja sie elip¬ tyczne. Pompy te maja równiez te wade, ze po¬ siadaja dwa otwory wylotowe, polaczone z jedna zbiorcza rura wylotowa.Znane sa równiez pompy z zaworami obroto¬ wymi, w których wprawdzie latwo mozna uszczel¬ nic dlawnice, lecz które posiadaja te wade, ze ze wzgledu na prace pompy za pomoca klap opado¬ wych zawieszonych na zawiasach, powstaje zbyt szybkie zuzycie wspólpracujacych z soba plasz¬ czyzn i zbyt halasliwa praca pompy. 25 30 2 Istnieja równiez pompy z konstrukcja dwura- miennych skrzydel obrotowych, które w swych obu polozeniach krancowych lacza na przemian jeden z dwu cylindrów pompy z otworem wylo¬ towym, przy równoczesnym polaczeniu drugiego cylindra z otworem ssacym. W pompach tego ty¬ pu, choc uszczelnienie zewnetrzne jest latwe do zalozenia ze wzgledu na obrotowy ruch cienkiego czopa i konstrukcja pompy posiada niewielka po¬ wierzchnie tarcia wspólpracujacych ze soba ele¬ mentów, to jednak wada tej konstrukcji pojawia sie w niekorzystnym przeplywie betonu, powo¬ dujacym czeste zatykanie sie pompy.Celem wynalazku jest usuniecie powyzszych wad charakteryzujacych sie zbyt szybkim zuzyciem elementów slizgowych, powstawaniem nieszczel¬ nosci i niekorzystnych warunków przeplywu beto¬ nu zarówno po stronie ssacej jak tez i po stronie tloczacej pompy.Zadanie to zgodnie z wynalazkiem rozwiazane zostalo w ten sposób, ze po obu stronach otworu wylotowego, klapy zaworowe posiadajace równo¬ legle i obrotowo ulozyskowane osie lacza na prze¬ mian jeden z dwu cylindrów pompy z otworem tloczacym przy równoczesnym polaczeniu drugie¬ go cylindra z odpowiednim otworem ssacym.Przedmiot wynalazku jest uwidoczniony w przy¬ kladzie wykonania na rysunku, na którym fig. 1 przedstawia w przekroju poziomym A—A obu- 7118571185 dowe obu cylindrów pompy do betonu i fig. 2 — w przekroju pionowym wzdluz linii B—B jeden cylinder pompy.Jak uwidoczniono na fig. 1 i 2 w cylindrach 1 i 2 umieszczone sa w przeciwtakcie tloki 3 i 4.Na obudowie 5 ulozyskowane sa obrotowo na osiach C i D klapy sterujace 6 i 7.Klapy 6 i 7 przy odpowiednim ustawieniu two¬ rza przegrode miedzy otwarami ssacymi 9 i 10 a otworem tloczacym 8. Klapa sterujaca 6 zamyka otwór ssacy 9 w tym czasie, gdy klapa sterujaca 7 pozostawia otwór ssacy 10 otwarty do cylindra 10 pompy 2. Naped obu klap sterujacych 6 i 7 od¬ bywa sie za pomoca dzwigni 11 i 12. PL PLThe rights holder of the patent: Friedrich Schwing, Wanne Eickel (Federal Republic of Germany) Concrete pump with two cylinders and a common outlet The subject of the invention is a concrete pump with two cylinders and a common outlet. Concrete pumps are known, which have various control systems, the most popular are pumps with flat slides making a reciprocating movement by means of an eccentric combined with a piston mechanism, thanks to which the control channels to the pump cylinder are opened and closed. it has a disadvantage, which is characterized by too rapid wear of the slide faces and the formation of a leak between the slide and the slide surface on which the slide slides, and between the slide guiding bars and the sealing glands. The sealing of the rods becomes more and more difficult over time as they lose their round shape and become elliptical. These pumps also have the disadvantage that they have two outlet openings connected to a single outlet manifold. Rotary valve pumps are also known, where the stuffing box can be easily sealed, but have the disadvantage that Due to the operation of the pump by means of hinged drop dampers, too rapid wear of the cooperating surfaces and too noisy operation of the pump arise. There are also pumps with the construction of double-arm swivel blades which, in their two end positions, alternately connect one of the two pump cylinders to the outlet port, while simultaneously connecting the other cylinder to the suction port. In pumps of this type, although the outer seal is easy to install due to the rotational movement of the thin spigot and the pump structure has a low friction surface of the mating components, the disadvantage of this structure appears in the unfavorable flow of concrete, The aim of the present invention is to eliminate the above-mentioned disadvantages characterized by too rapid wear of the sliding elements, the formation of leaks and unfavorable concrete flow conditions both on the suction side and on the discharge side of the pump. In this way, on both sides of the outlet opening, valve flaps having parallel and rotatably mounted shaft axles alternating between one of the two pump cylinders with a discharge opening at the same time connecting the second cylinder with a suitable suction opening. shown in the embodiment in the drawing in which FIG. 1 shows in a horizontal section A-A of both concrete pump cylinders and Fig. 2 - in a vertical section along the line B-B one pump cylinder. As shown in Figs. 1 and 2 in cylinders 1 and 2 are placed in counter-contact pistons 3 and 4 on the housing 5 are rotatably mounted on the C and D axes, control flaps 6 and 7. 9 while the control flap 7 leaves the suction opening 10 open to the cylinder 10 of the pump 2. Both control flaps 6 and 7 are driven by lever 11 and 12. EN EN
