Description

Wynalazek niniejiszy unioizliiwiiia sizczie- gólnie latwe naciaganie lub wymiane usze¬ regowanych jednostronnie na dzwigarach swobodnie wahliwych rusztowin bez potrze¬ by wyjmowania pomienionych dzwigarów z ich lozysk w bocznych lancuchach naped- nych.Wynalazek przedstawia .zalaczony ry¬ sunek, a mianowicie, na fig. 1 — w widoku bocznym koniec tylny rusztu ruchomego, na fig. 2 — przekrój poprzeczny czesci' dol¬ nej rusztu, przyczem strona lewa unaocznia wypadek, gdy dzwigar rusztowin posiada ksztalt dwuteowy, strona zas prawa wypa¬ dek dzwigara o przekrój ul okraglym, fig. 3 przedstawia rusztowine, fig. 4 — dzwigar rusztowin i fig. 5 — tarcze zabezpieczajaca.W napednych lancuchach bocznych a osadzone sa dzwigary b, na których osa¬ dza sie rusztowiny c. Dzwigary b posiadaja obrysie dwuteowe lub okragle, przyczem na koncach ich kryzy e sa sciete tak, iz pozo¬ staje tylko pas srodkowy /, w wypadku zas dzwigarów okraglych konce ich zostaja splaszczone. Rusztowiny c posiadaja w s^gych piastach szczeliny g.W celu naciagniecia! rusztowin c na dzwigary b naklada sie je od dolu szczeli¬ nami g na koniec dzwigara, gdzie kryzy e sa sciete lub sam dzwigar splaszczony, a nastepnie przesuwa sie wzdluz kryzy e.Poniewaz dzwigary b wraz z kryzami e sa szersze od szczelin g w rulsztowinach c, te ostatnie nie moga przeto spasc z pomienio¬ nych dzwigarów nawet przy dojsciu rusztu do konca swej drogi, gdy sie odwracaja.W celu zapobiezenia spadaniu ruszto^ win z belek b po-dcza? pracy rusztu na kon- V cachJ belek osadzone sjfc tarcze h, które po przysunieciu ich do kryz e zabezpiecza sie od dalszych ruchów zatyczkami i.Wymiana uszeregowanych na poprzecz¬ nych dzwigarach ruchomych rusztowan jest wprawdzie wogóle znana, nigdzie wszelako nie stosowano jej w wypadkach, gdy ru- • sztowiny umieszczone sa na dwu belkach poprzecznych, albo przy rusztowinach u- szeregowanych jednostronnie na dzwiga¬ rach poprzecznych. Istote wynalazku sta¬ nowi przeto swobodne wahanie sie po¬ szczególnych wolno zwisajacych nadól ru¬ sztowin w celu uwolnienia ich od przylega¬ jacych zuzli w koncu tylnym droigi rusztu, gdzie rusztowiny ulegaja wywrotowi, i za¬ bezpieczenie ich od spadania. Zgodnie z wynalazkiem niniejszym rusztowi|na nakla¬ da sie nie, jak to zwykle ma miejsce, przez ibolnilec dlzwigaira, alle dio^iiero zla czopem w punkcie k oddalonym od konca, dzieki czemu dzwigar rusztowin pozostaje stale w lozyskach lancuchów. PLThe present invention makes it particularly easy to tension or replace the freely pivoting grates arranged on one side on the girders without the need to remove said girders from their bearings in the lateral drive chains. The invention is shown in the drawing shown in Fig. 1 - in the side view, the rear end of the movable grate, in Fig. 2 - the cross-section of the lower part of the grate, with the left side showing the case where the girder of the scaffolding has an I-shape, while the right side is the spar's fall with a circular cross-section, Fig. 3 shows the grate bars, Fig. 4 - girder of gratings and Fig. 5 - securing shields. In the drive side chains a, there are girders b, on which the gratings are placed c. The girders b have I-shaped or circular contours, with their ends resting on them. the flanges are cut so that only the middle strip remains /, and in the case of round girders their ends are flattened. C grates have slots g in their gaps. To tighten! scaffoldings c are placed on the girders b from the bottom with the slots g at the end of the girder, where the flanges e are cut or the flattened girder itself, and then it moves along the flange e. Because the girders b with flanges e are wider than the gaps in the coils c , the latter, therefore, must not fall off the devastated girders, even when the grate reaches the end of its path, when they turn backwards. of the work of the grate, sjfc shields h are mounted on the ends of the beams, which, after they are brought to the flanges, are secured against further movements with plugs i. The replacement of the scaffolding arranged on the transverse mobile girders is indeed known at all, but nowhere was it used in cases, when the pipes are placed on two transverse beams, or at the grate bars arranged on one side on the transverse girders. The essence of the invention is therefore the free swing of the individual, slowly hanging above the pipelines in order to free them from adjacent slugs at the rear end of the grate path, where the grates tip over, and to prevent them from falling off. According to the present invention, the grate is not, as is customary, applied to the girder of the girder, but to the bolt at a point k distant from the end, so that the girder of the girders remains permanently in the bearings of the chains.
