Description

Pierwszenstwo: 49847 KI 35 b,*?flWr- MKP B 66 c Opublikowano: 2. Xl. 1965 UKD iJBJflOTSNA Wspóltwórcy wynalazku: inz. Tadeusz Skalon, Józef Pociecha Wlasciciel patentu: Huta im. Lenina, Kraków (Polska) Urzadzenie doprowadzajace napiecie do aparatury elektrycznej na wózku suwnicy Przedmiotem wynalazku jest urzadzenie dopro¬ wadzajace napiecie do aparatury znajdujacej sie na wózku suwnicy, eliminujace calkowicie troleje i zbieracze pradu. Napiecie do urzadzen elek¬ trycznych znajdujacych sie na wózku suwnicy do¬ prowadzane jest najczesciej za pomoca trolei skla¬ dajacych sie z przewodników pretowych lub ka¬ towników wraz z zbieraczami pradu slizgowymi w skomplikowanym osprzecie izolacyjnym.Urzadzenie tego typu szczególnie w przypadku pracy suwnic przy duzych wstrzasach i w po¬ mieszczeniach zapylonych nie gwarantowalo sta¬ lego polaczenia elektrycznego, powodujac duze iskrzenia wskutek czego zespoly ze soba wspól¬ pracujace ulegaly szybkiemu zuzyciu i niekiedy zniszczeniu w wyniku zwarc. Niezaleznie od tego suwnice pracujace z tymi urzadzeniami w po¬ mieszczeniach o duzym zapyleniu, gazowo niebez¬ piecznych itp. stwarzaly niebezpieczenstwo poza¬ ru z powodu iskrzenia, natomiast suwnice pracu¬ jace na zewnatrz w okresie zimowym ulegaly przestojom na skutek odblodzenia trolei.Odizolowane przewody na mostach suwnic by¬ ly równiez powodem wypadków porazenia obslugi.Urzadzenie wedlug wynalazku usuwa powyzsze wady i zapewnia pelne bezpieczenstwo pozarowe i bezpieczne dla otoczenia warunki pracy.Przykladowe rozwiazanie konstrukcji urzadze¬ nia wedlug wynalazku pokazano na rysunku, na którym fig. 1 przedstawia urzadzenie zamontowa¬ ne na pomoscie suwnicy w widoku z góry, fig. 2 — to samo urzadzenie w widoku z boku od strony czolownicy, fig. 3 — urzadzenie w widoku z boku od strony belki suwtiicy, a fig. 4 — fragment ulo- 5 zenia przewodów kablowych. Urzadzenie wedlug wynalazku jest zainstalowane na pomoscie suw¬ nicy, na którym w miejscu 1 przeznaczonym dla trolei ulozono wzdluz mostu lekkie szyny jezd¬ ne 2, po których tocza sie kola 3 wózka kablowe- 10 go 4 wykonanego na ksztalt ramy, równej polowie dlugosci mostu suwnicy.W ramie wózka 4 po obu jej krancach zamonto¬ wano dwa bebny 9 o srednicy i szerokosci zalez¬ nej od grubosci uzytych kabli, pomiedzy które 15 rozciagnieto odpowiednio szeroka tasme transpor¬ terowa 10, zamocowana koncami w srodku pode¬ stu 11, tworzaca w ten sposób zamkniety obwód.Ramie (gitare) 6 wózka suwnicy 7 zamocowano 20 na stale zlaczem 12 w srodku dlugosci tasmy 10, aby w ten sposób wózek 7 podczas jazdy w jedna lub druga strone napedzal równoczesnie wózek kablowy 4.Do tasmy transportera 10 przymocowano uchwy- 26 tami 8 przewody gietkie 5, których ilosc i prze¬ kroje zyl uzaleznione sa od poboru pradu przez aparature elektryczna znajdujaca sie na wózku suwnicy 7, przy czym przewody wychodzace z ka¬ biny lub szaf stycznikowych polaczono w srodku 30 podestu 11. ' W celu zlikwidowania zwisu tasmy 4984749847 10, wystepujacego szczególnie przy dlugich mo¬ stach, zastosowano rolki 13. PL PLPriority: 49847 KI 35 b,*?flWr- MKP B 66 c Published: 2 Xl. 1965 UKD iJBJflOTSNA Co-inventors of the invention: engineer Tadeusz Skalon, Józef Pociecha Patent owner: Lenin Steelworks, Kraków (Poland) Device for supplying voltage to electrical equipment on an overhead crane trolley The subject of the invention is a device for supplying voltage to equipment on an overhead crane trolley, completely eliminating trolleys and current collectors. Voltage to electrical devices located on the crane carriage is most often supplied via trolleys consisting of bar or angle conductors with sliding current collectors in complex insulating equipment. This type of device, especially when the cranes operated under high vibrations and in dusty rooms, did not guarantee a constant electrical connection, causing large sparks, as a result of which the interconnected units were subject to rapid wear and sometimes destruction due to short circuits. Regardless of this, overhead cranes operating with these devices in rooms with high dust levels, gas hazards, etc. posed a fire hazard due to sparking, while overhead cranes operating outdoors in winter were subject to downtime due to de-icing of trolleys. Insulated wires on overhead crane bridges also caused accidents involving electric shock to the operators. The device according to the invention eliminates the above-mentioned disadvantages and ensures full fire safety and safe working conditions for the environment. An exemplary design solution of the device according to the invention is shown in the drawing, where Fig. 1 shows the device mounted on the overhead crane platform in a top view, Fig. 2 — the same device in a side view from the end carriage side, Fig. 3 — the device in a side view from the crane beam side, and Fig. 4 — fragment of the cable duct arrangement. The device according to the invention is installed on the bridge of an overhead crane, on which in the place 1 intended for the trolleys, light running rails 2 are placed along the bridge, on which the wheels 3 of the cable trolley 4 made in the shape of a frame, equal to half the length of the overhead crane bridge, roll. In the frame of the trolley 4, at both ends, two drums 9 are mounted, the diameter and width of which depend on the thickness of the cables used, between which an appropriately wide conveyor belt 10 is stretched, fastened with its ends in the middle of the platform 11, thus creating a closed circuit. The arm (guitar) 6 of the overhead crane trolley 7 is permanently fastened with a joint 12 in the middle of the length of the belt 10, so that the trolley 7 while moving in one or the other direction simultaneously drove the cable trolley 4. Flexible cables 5 were attached to the conveyor belt 10 with holders 8, the number and cross-sections of which depend on the current consumption of the electrical equipment located on the crane trolley 7, while the cables coming out of the cabin or contactor cabinets were connected in the center 30 of the platform 11. In order to eliminate the sag of the belt 4984749847 10, which occurs especially in long bridges, rollers 13 were used. PL PL
