Abstract

L'invenzione riguarda un dispositivo automatico per prove di sicurezza in ascensori idraulici ad azionamento indiretto che agisce su di un dispositivo (4, 5, 6) ad allentamento delle funi (3) di azionamento del sistema (8) di sicurezza dello ascensore, comprendente un tirante (2, 15) di fissaggio di una fune (1) ad un dispositivo di fissaggio (1), scorrevole rispetto al dispositivo di fissaggio (1) stesso di un tratto almeno pari al tratto di allentamento della fune (3) necessario per attivare detto dispositivo ad allentamento delle funi (4, 5, 6), un elemento di riscontro (14) portato su detto tirante (2, 15) di fissaggio, a monte di :detto dispositivo di fissaggio (1), un sistema di leve (9, 10, 12) che agisce su :detto riscontro (14) in modo da bloccarlo nella posizione della corsa del tirante (2, 15) di fissaggio più vicina al dispositivo di fissaggio (1). e da liberarlo in modo da consentire la corsa di detto tirante di fissaggio (2, 15), e mezzi (16) di azionamento del sistema di leve (9, 10, 12) a distanza.The invention relates to an automatic device for safety tests in indirectly operated hydraulic lifts which acts on a device (4, 5, 6) for loosening the cables (3) for operating the lift safety system (8), comprising a tie rod (2, 15) for fixing a rope (1) to a fixing device (1), sliding with respect to the fixing device (1) by a section at least equal to the slackening section of the rope (3) necessary for activating said cable slackening device (4, 5, 6), a striker element (14) carried on said fixing tie rod (2, 15), upstream of: said fixing device (1), a lever system (9, 10, 12) which acts on: said striker (14) so as to lock it in the position of the travel of the fixing tie rod (2, 15) closest to the fixing device (1). and to be released so as to allow the travel of said fixing tie-rod (2, 15), and means (16) for operating the lever system (9, 10, 12) remotely.
