Abstract

Inventia se refera la o instalatie pentru montarea grinzilor prefabricate la viaductele de cale ferata, la care suprastructura se afla la înaltime, deschiderea dintre pile fiind variabila, traversarea de catre vuaducte a unor terenuri inaccesibile, executie de viaducte în aliniament si în curba. Instalatia conform inventiei este alcatuita dintr-un ansamblu lansator, care se poate deplasa de-a lungul unei cai de rulare pe patru fire, montate initial pe o culee si pe o platforma a viaductului în constructie, pe lansator deplasându-se doua miniporiale prevazute cu niste trolii mecanice care actioneaza niste mufle cu ochet, de care se agata dispozitivele de prindere a grinzii prefabricate de montat, ansamblul lansator fiind compus din doua grinzi principale, niste antretoaze, un tren de rulare motor, un alt tren de rulare liber, un dispozitiv de calare cu o traversa de asezare, o alta traversa articulata, între care sunt plasate doua dispozitive de reglare cu surub, o contragreutate de lestare si o cale de rulare pentru cele doua miniportale, ce este alcatuit dintr-o constructie metalica, un tren de rulare, o cale de rulare transversala, pe care se deplaseaza un carucior de sarcina, format dintr-un sasiu, un troliu, un mecanism de deplasare, o mufla cu ochet, un bloc de role ce formeaza palanul, un limitator de sarcina si un limitator de cursa, actionarea si comanda tuturor menevrelor realizându-se de la o cabina de comanda cu ajutorul unei scheme electrice, ce are în componenta elemente pentru comanda motoarelor carucioarelor de translatie a lansatorului, a motoarelor carucioarelor de deplasare a miniportalelor, si motoarele troliilor de ridThe invention relates to a plant for mounting prefabricated beams on railway viaducts, the superstructure of which is at a height, the opening between the piles being variable, the passage through untouched lands of inaccessible land, the execution of viaducts in the alignment and in the curve. The installation according to the invention consists of a launcher assembly, which can be moved along a four-wire running track, initially mounted on a harrow and on a platform of the viaduct under construction, on the launcher moving two miniporals provided with some mechanical winches which act as a muffle with the hooks fastened to the fastening devices of the prefabricated beams to be assembled, the launcher assembly being composed of two main beams, one sidewalk, one motor running train, another running train, one device with a crossbar, another articulated cross member, between which are two screw-adjusting devices, a lever counterweight and a running track for the two miniportable ones, which consists of a metal construction, a train of rolling, a transverse rolling path, on which a load cart is moved, consisting of a chassis, a winch, a travel mechanism, a muffle muffler, a roller block forms a hoist, a load limiter, and a curb limiter, driving and commanding all menevres from a command cab with an electric scheme that includes components for commanding the engines of the trolley launchers, trolley motors moving miniporters, and wreckage winch engines
