Description

Przedmiotem wynalazku jest ulepszenie podpory do maszyn budowlanych, zwlaszcza do dzwigów i koparek jezdnych, skladajacej sie z pochwy i wsporników napedzanych hydraulicznie wedlug patentu glównego nr 78 154.Zgodnie z patentem nr 78 154 podpora teleskopowa sklada sie ze wspornika wewnetrznego, majacego zaczep wspólpracujacy z wybraniem wspornika zewnetrznego posiadajacego wystep wspólpracujacy z zaczepem pochwy. Obie podpory — lewa i prawa — usytuowane sa w jednej pochwie osiowo, a napedzane sa poprzez silowniki hydrauliczne, którychjedne konce polaczone sa z pochwami, a drugie ze wspornikami wewnetrznymi.Niedogodnosc tego rozwiazania polega na tym, ze wybranie wspornika zewnetrznego zmniej¬ sza jego wytrzymalosc, zas wykonanie zaczepu umocowanego do wspornika wewnetrznego jest zbyt pracochlonne.W tym celu opracowane zostalo rozwiazanie, stanowiace uzupelnienie do patentu glównego polegajace na tym, ze do wewnetrznej pochwy oraz do wspornika zewnetrznego zamocowane sa za pomoca elementów zlacznych zaczepy wspólpracujace z wystepami, które zamocowane sa do zewnetrznej powierzchni wspornika zewnetrznego oraz do wspornika wewnetrznego. Obie pod¬ pory — lewa i prawa — maja identyczna budowe.Zaletami takiego rozwiazania sa przede wszystkim, prostota i unifikacja wykonania podpory wedlug wynalazku o zwiekszonej wytrzymalosci oraz pewnosci dzialania.Przedmiot wynalazku jest uwidoczniony w przykladzie wykonania na rysunku, którego fig. 1 przedstawia podpore rozsunieta w przekroju wzdluznym, a fig. 2 — podpore rozsunieta w widoku z góry.Jak przedstawiono na rysunku, do pochwy 1 od strony wewnetrznej, za pomoca elementów zlacznych 6 zamocowany jest zaczep 4. Suwliwie usytuowany w pochwie 1 zewnetrzny wspornik 2 jest zaopatrzony od strony zewnetrznej w wystep 5, zas od strony wewnetrznej w zaczep 4.2 120 943 Wewnatrz zewnetrznego wspornika 2 znajduje sie wewnetrzny wspornik 3, zaopatrzony od strony zewnterznej w wystep 5. Podpora napedzana jest silownikiem 7 hydraulicznym, którego jeden koniec polaczony jest ze wspornikiem wewnetrznym 3, a drugim koncem z pochwa 1. Rozsuniety stan podpory uzyskuje sie przez zadzialania silownika 7, który powoduje wysuwanie sie wspornika zewnetrznego 2 i wspornika wewnetrznego 3, az do oparcia zaczepów 4 o wystepy 5. Zsuwanie podpory uzyskuje sie zas przez dzialanie silownika 7 w druga strone, tojest wsuniecie zewnetrznego wspornika 2 i wewnetrznego wspornika 3 do srodka pochwy 1.Zastrzezenie patentowe Podpora do maszyn budowlanych, zwlaszcza do dzwigów i koparek jezdnych, skladajaca sie ze wspornika z zaczepem, suwliwie przemieszczajacym sie w prowadzeniu wspornika zewnetrznego osadzonego suwliwie w pochwie, które od wewnatrz zaopatrzone jest w zaczep wspólpracujacy z wystepem zewnetrznego wspornika wedlug patentu glównego nr 78 154, znamienna tym, ze zewnetrzny wspornik (2) zaopatrzony jest za pomoca elementów rozlacznych (6) w zaczep (4), a wewnetrzny wspornik (3) zaopatrzony jest w wystep (5). / 5 4 2 5 4 3 Fig.1 L 7 5 4 2 5 4 3 Fig 2 Pracownia Poligraficzna UP PRL. Naklad 120 egz.Cena 100 zl PLThe object of the invention is to improve the support for construction machines, especially for cranes and mobile excavators, consisting of a sheath and hydraulically driven supports according to the main patent No. 78 154. According to the patent No. 78 154, the telescopic support consists of an internal support having a catch cooperating with the recess an outer bracket having a projection cooperating with the vaginal hook. Both supports - left and right - are located in one sheath axially and are driven by hydraulic cylinders, the ends of which are connected to the sheaths and the other to the internal supports. The disadvantage of this solution is that choosing the external support reduces its strength. However, the implementation of the hook attached to the inner support is too laborious. For this purpose, a solution was developed that complements the main patent, whereby the inner scabbard and the outer support are fastened with fasteners cooperating with the protrusions that are attached to the outside of the outer bracket and to the inner bracket. Both supports - left and right - have the same structure. The advantages of such a solution are, above all, simplicity and unification of the support according to the invention with increased strength and reliability of operation. The subject of the invention is shown in the example of embodiment in the drawing, Fig. 1 shows the support 2 is extended in longitudinal section, and in Fig. 2 the support is folded out from above. As shown in the drawing, a hook 4 is attached to the scabbard 1 from the inside by means of fasteners 6. The outer support 2 is slidably located in the scabbard 1 and is provided with from the outside to the projection 5, and from the inside to the catch 4.2 120 943 Inside the external support 2 there is an internal support 3, provided on the outside with a projection 5. The support is driven by a hydraulic cylinder 7, one end of which is connected to the internal support 3, and the scabbard with the other end 1. The extended state of the support is obtained by the action of forces nika 7, which causes the outer bracket 2 and the inner bracket 3 to slide out until the tabs 4 rest on the projections 5. The sliding of the support is achieved by the action of the actuator 7 on the other side, i.e. the insertion of the outer bracket 2 and the inner bracket 3 into the center of the vagina 1 Patent claim A support for construction machinery, in particular for cranes and mobile excavators, consisting of a support with a catch, sliding smoothly in the guide of the external support slidably mounted in the sheath, which from the inside is provided with a catch cooperating with the protrusion of the outer support of the support according to patent no. 78 154, characterized in that the outer bracket (2) is provided with a catch (4) by means of detachable elements (6) and the inner bracket (3) is provided with a projection (5). / 5 4 2 5 4 3 Fig. 1 L 7 5 4 2 5 4 3 Fig 2 Printing studio of the PRL.
