Description

Przedmiotem wynalazku jest suwnica podwieszona uzyteczna w transporcie bliskim.Dotychczas sa znane i powszechnie stosowane suwnice podwieszone, w których dzwigar polaczony jest sztywno z czolownicami, a kazda czolownica wyposazona jest w wózek napedzany i nienapedzany. Na dzwigarze podwieszony jest przejezdny wciagnik.Taka suwnica pracuje poprawnie przy dokladnym zachowaniu równoleglosci toru. Natomiast w przypadku wystepowania wiekszych odchylek wystepuja dodatkowe sily, powodujace zwiek¬ szone zuzycie kól jezdnych i jezdni. Ponadto suwnica nie nadaje sie do pracy po torze o ksztalcie kolowym.Istota rozwiazania wedlug wynalazku polega na tym, ze dzwigar suwnicy polaczony jest z czolownica stala poprzez wieszak umozliwiajacy obrót dzwigara wzgledem osi wieszaka, a z czolownica kompensacyjna dzwigar polaczony jest przez wieszak z wózkiem kompensatora, którego rolki przejezdne wspólpracuja z jezdnia kompensatora dzwigara suwnicy. Czolownice polaczone sa z wózkiem napedzanym i z wózkiem poprzez wieszaki czolownicy. Na dzwigarze suwnicy jest osadzony przejezdny wciagnik.Suwnica dzieki temu, ze ma kompensacyjne polaczenie czolownicy kompensacyjnej z dzwiga¬ rem oraz dzieki temu, ze dzwigar na czolownicy zawieszonyjest poprzez wieszaki, moze swobodnie poruszac sie po torze o róznej rozpietosci, jak równiez po torze kolowym.Wynalazek jest blizej objasniony w przykladzie wykonania pokazanym na rysunkach, na których fig. 1 przedstawia suwnice w widoku, fig. 2—suwnice w widoku z boku, a fig. 3 — szczegól polaczenia dzwigara z czolownica kompensacyjna.Dzwigar 10 polaczony jest z czolownica stala 4 poprzez wieszak 9, a z czolownica kompensa¬ cyjna 5 dzwigar 10 polaczony jest poprzez wieszak 9 z wózkiem kompensatora 7, którego rolki przejezdne 13 wspólpracuja zjezdnia kompensatora 6 dzwigara lO.Czolownice 5i 6 polaczone sa z wózkiem napedzanym 2 z wózkiem nienapedzanym 3poprzez wieszaki czolownicy 12. Wieszak 9 w czolownicy kompensacyjnej 5 osadzony jest za pomoca sworznia 8, zas w wózku kompensatora 7 wieszak 9 ustalony jest nakretka 14 i plytka zabezpieczajaca 15. Suwnica porusza sie po belkach jezdnych 1, a na dzwigarze suwnicy 10 porusza sie wciagnik 11.2 126410 Zastrzezenie patentowe Suwnica podwieszona skladajaca sie z dzwigara, po którym porusza sie wciagnik i z dwóch czolownic kazda polaczona z wózkiem napedzan\m i z wózkiem nienapedzanym wspólpracuja¬ cych z belkami jezdnymi, znamienna tym, ze dzwigar suwnicy (10) polaczony jest zczolownica stala (4) poprzez wieszak (9) umozliwiajacy obrót dzwigara (10) wzgledem osi wieszaka (9), a z czolow- nica kompensacyjna (5) dzwigar (10) polaczony jest poprzez wieszak (9) z wózkiem kompensatora (7), którego rolki przejezdne (13) wspólpracuja z jezdnia kompensatora (6) dzwigara suwnicy (10), a ponadto czolownice (5 i 6) polaczone sa z wózkiem napedzanym (2) i z wózkiem nienapedzanym (3) poprzez wieszaki czolownicy (12).Rg. 1 Rg. 2126 410 6 7 JL Fig. 3 PLThe subject of the invention is a suspended overhead crane useful in short-distance transport. Until now, there are known and commonly used suspended overhead traveling cranes, in which the girder is rigidly connected to the endcarriages, and each endcarriage is equipped with a driven and not driven trolley. A mobile hoist is suspended on the girder. Such an overhead crane works properly with the exact maintenance of the track parallelism. On the other hand, when larger deviations occur, additional forces occur, causing increased wear of the road wheels and the road. Moreover, the gantry crane is not suitable for working on a circular-shaped track. The essence of the solution according to the invention is that the girder of the gantry is connected with the fixed endcarriage through a hanger that enables the girder to rotate in relation to the axis of the hanger, and that the compensating end-member, the girder, is connected by the hanger with the compensator carriage, whose traveling rollers cooperate with the carriageway of the girder girder compensator. The cantilever trucks are connected to the driven trolley and the trolley through the cantilever hangers. A traveling hoist is mounted on the girder of the crane. The gantry crane, due to the fact that it has a compensating connection between the compensating end beam and the crane, and the girder on the endcarriage is suspended by hangers, can move freely along a track of various spans, as well as on a circular track. The invention is explained in more detail in the example of the embodiment shown in the drawings, in which Fig. 1 shows the overhead traveling cranes, Fig. 2 - side view overhead traveling cranes, and Fig. 3 - a detail of the girder and compensating end beam connection. The girder 10 is connected to a fixed endcarriage. 4 through the hanger 9, and with the compensating beam 5, the beam 10 is connected through the hanger 9 with the compensator's carriage 7, the movable rollers 13 of which cooperate with the compensator's slide 6 of the beam 10. The towers 5 and 6 are connected with the driven carriage 2 with the non-driven carriage 3 through the suspension of the endcarriage 12 The hanger 9 in the compensator 5 is mounted by means of the pin 8, and in the compensator carriage 7 it is mounted. The jack 9 is fixed with a nut 14 and a securing plate 15. The crane moves along the running beams 1, and a hoist 11.2 moves on the crane girder 10. 126410 Patent claim. driven by a non-driven trolley cooperating with the traveling beams, characterized in that the girder of the crane (10) is connected with the fixed face beam (4) through the hanger (9), which enables the girder (10) to rotate in relation to the hanger axis (9), and to the forehead compensator (5) girder (10) is connected through the hanger (9) with the compensator carriage (7), whose movable rollers (13) cooperate with the compensator road (6), the crane girder (10), and also the endcarriages (5 and 6) are connected are with a driven carriage (2) and a non-driven carriage (3) through the hangers of the endcarriage (12) .Rg. 1 Rg. 2126 410 6 7 JL Fig. 3 GB
