Description
Przedmiotem wynalazku jest urzadzenie do usta¬ wiania kozlów hydraulicznych obudowy krcczacej przy wybieraniu poprzecznym, z umieszczonymi jeden za drugim stojakami, które sa przemieszcza¬ ne przegubowo na plozie spagowej i podpieraja przegubowo ciag stropnicowy pomiedzy stojakami, przy czym do ustawiania i podpierania stojaków sa przewidziane cylindry ustawcze o zmiennej dlugosci.The subject of the invention is a mouth device tying the hydraulic trestles of the terminal block with transverse removal with placed one behind the other stands that are being moved articulated on a spag slide and propped up articulated roof string between stands, for positioning and supporting the stands variable setting cylinders are provided length.
Przy eksploatacji stromych pokladów stojaki osadzonych kozlów obudowy powinny przyjmowac odpowiednie polozenie, skierowane lekko przeciw¬ nie do spadku. Na stojaki wywierany jest jednak przez ciezar obciazonych glowic ciagu stropnicy i zamocowanych na niej urzadzen podpierajacych, przeznaczonych dla ociosu wegla, moment sily, skierowany w strone spadku. Przy stosowaniu znanych kozlów obudowy kroczacej sa z tego po¬ wodu przewidziane do stabilizacji stojaków ele¬ menty sprezynowe, zamocowane na konstrukcji spagowej, które zazebiaja sie w dolnym zasiegu stojaków z rurami zewnetrznymi. Dodatkowo wzmacnia sie tu sile cofajaca za pomoca prze¬ mieszczanych na konstrukcji spagowej, hydrau¬ licznych lub obciazonych sprezyna cylindrów ustalajacych, ustawianych ukosnie do spadku, które zazebiaja sie równiez z dolnymi rurami zewnetrznymi stojaków przednich. Sily cofajace skierowane poprzecznie do osi wzdluznej stoja¬ ków, siegaja jednak, zwlaszcza przy wysunietych stojakach daleko pomdzej punktu iciezkosci jed¬ nostki obudowy -tak, ze na stojaki te sa wywierane duze momenty gnace. Ponadto jest tu wymagana kosztowna konstrukcja spagowa z elementów ze ©tali sprezynujacej, itotóra — jak i ukosnie usta¬ wiony cylinder ustawczy — znacznie utrudnia przesuw obudowy. Stabilizacja jest zwiazana z konstrukcja, w której rura zewnetrzna stojaka jest umieszczona na spagu jako rura stojakowa. ]0 Zadaniem wynalazku jest skonstruowanie takie¬ go urzadzenia do ustawiania stojaków obudowy przy wybieraniu poprzecznym, które przy zaloze¬ niu duzego i latwo obslugiwanego przekroju po¬ przecznego drogi przesuwu umozliwia w obudowie optymalne ustawianie stojaków z wyeliminowa¬ niem dodatkowych momentów gnacych, jakie sa wywierane na stojaki przez urzadzenie do usta¬ wiania.Stands for steep decks seated trestles should take the housing correct position, directed slightly against not to fall. However, it is exerted on the racks by the weight of the head of the canopy load loaded and the supporting devices attached to it, intended for the side of the coal, moment of force, directed towards the decline. When applying known trestles of the cantilever are from this half water intended to stabilize the electric stands spring loaded on the structure spagowej, which overlap in the lower range racks with external pipes. Additionally Here, the force of retraction is amplified by means of a switch housed on a spag construction, hydraulic multiple or spring-loaded cylinders fixing, set diagonally to the slope, which also mesh with the down tubes external front racks. Recalling forces directed transversely to the longitudinal axis stand however, they do, especially when they are extended stands far away from the point of chill housing units - so that these racks are exerted big rushing moments. Moreover, it is required here expensive spag construction made of stainless steel elements © the spring waist, and the slanting mouth vertical alignment cylinder - makes it much more difficult housing shift. Stabilization is related to structure in which the outer tube of the rack it is placed on the spag as a standpipe. ] 0 The object of the invention is to construct one device for positioning the housing stands in transverse extraction, which large and easily operated cross-section cross travel allows in the housing optimal positioning of stands with elimination without the additional bending moments that are exerted on the stands by the mouth device swings.
Zadanie to rozwiazano wedlug wynalazku w ten sposób, ze cylinder ustawczy kazdego kozla obu¬ dowy kroczacej jest ulozyskowany iwychylnie na podciaganej do góry podporze, umieszczonej na koncu plozy spagowej, przedluzonym od strony podsadzki oraz jest skierowany diagonalnie do 29 spadku i zazebia sie przegubowo z ciagiem strop¬ nicowym pomiedzy przednim a tyOnym stojakiem.This task was solved according to the invention in this the way that the setting cylinder of each goat was both the crawling day is located and leaning towards a pull-up support located on the the end of the spagic slide, extended from the side proppant and is directed diagonally to the 29 slope and articulated with the ceiling string between the front and rear rack.
Koziol obudowy kroczacej jest podparty w kaz¬ dym polozeniu wysunietym stojaków powyzej punktu ciezkosci jednostki obudowy za pomoca so skierowanego diagonalnie cylindra ustawczego, 93 31993 319 przemieszczanego na plozie spagowej oraz zazebia- jacego sie ze stropnica i przeciwdzialajacego sile ciezkosci. Wskutek tego stojaki sa odciazane od momentów gnacych, wynikajacych z ukosnego po¬ lozenia obudowy w obudowywanym w sposób pod¬ wieszony wyrobisku. Przez zastosowanie zarówno funkcjonalnego jiak i przestrzennie korzystnego ukladu cylindrów ustawczyeh stwarza sie duza i wolna od .przeszkód droge przesuwu w obudo¬ wie pomiedzy .przednimi i tylnymi stojakami dla wzglednie wygodnej obslugi i konserwacji obudowy.The trestle of the walking casing is supported in each case smoke racks raised above center of gravity of the housing unit with with a diagonally facing setting cylinder 93 31 993 319 moved on the spag sledge and jacquard with a bar and counteracting force gravity. Consequently, the racks are relieved of the load bending moments resulting from oblique sweeps to place the housing in the enclosed in a way hung excavation. By the use of both functional jiak and spatially beneficial the arrangement of the positioning cylinders becomes large and an obstruction-free path in the housing knows between .front and rear racks for relatively convenient operation and maintenance of the housing.
Podczas luzowanda i rabowania stojaków dla cof¬ niecia kozla obudowy kroczacej cylinder ustawczy jest mocowany w jego dlugosci wysuwania tak ze stojaki nie przychylaja sie z powrotem a tylko sa pochylane do przodu w kierunku spadku wy¬ robiska.
