Abstract

Mécanisme destiné à limiter l'angle de pivotement d'un bras (1) d'une perforatrice de roches lorsque ledit bras (1) est levé ou abaissé. Dans ce mécanisme, un élément de commande (12) est couplé au bras (1), tournant avec ce dernier, ledit élément comprenant une fente (13) dotée d'un goujon mobile (14). Le goujon (14) est couplé de manière à commander une soupape de sûreté (16) si bien que, lorsque le bras est levé ou abaissé et qu'il a tendance à tourner au-delà de l'angle de rotation maximal permissible, l'élément de commande actionne la soupape de sûreté afin que cette dernière laisse entrer du fluide hydraulique dans le vérin de pivotement (4) pour faire pivoter le bras dans la direction inverse.
