Abstract

Viene descritto un dispositivo di controllo dell'integrità di molle, in particolare di molle per morse di serraggio per l'aggancio di veicoli ad una fune in impianti funiviari.Secondo l'invenzione il dispositivo di controllo è costituito da un elemento sensore (14, 19) atto a permettere, con moto relativo fra molla (9) ed esso, il passaggio libero alla molla (9) al suo stato caricato per il serraggio corretto della morsa (1) sulla fune e ad interferire in questo movimento relativo quando è variata la geometria della molla (9) rispetto a quella dello stato caricato correttamente, da un attuatore (11) sensibile all'interferenza fra l'elemento sensore (14, 19) e la molla (9) e da un organo di comando (20, 21) collegato efficacemente con l'attuatore (11) e capace di fornire un segnale ad un impianto di segnalazione e/o di fermata dell'impianto funiviario.FiguraA device for checking the integrity of springs, in particular of clamping vice springs for hooking vehicles to a rope in ropeway systems, is described. According to the invention, the control device is constituted by a sensor element (14, 19) adapted to allow, with relative motion between the spring (9) and it, the free passage to the spring (9) in its loaded state for the correct tightening of the vice (1) on the rope and to interfere in this relative movement when it has changed the geometry of the spring (9) with respect to that of the correctly loaded state, by an actuator (11) sensitive to the interference between the sensor element (14, 19) and the spring (9) and by a control element (20, 21) effectively connected with the actuator (11) and capable of providing a signal to a signaling and / or stopping system of the cableway system.
