Abstract

La présente invention concerne un dispositif de commande de mise en serrage complémentaire pour soutènement de taille dans des exploitations minières souterraines, ce dispositif comportant une vanne de commande de mise en serrage complémentaire placée dans la conduite conduisant au piston et un organe d'isolement, manîoeuvrable à la main, prévu dans une canalisation reliant la canalisation d'amenée du fluide haute pression et la vanne de commande de mise en serrage complémentaire. Ce dispositif est caractérisé en ce qu'à l'organe d'isolement 3 est associé un commutateur 4 pourvu d'un piston de commande qui est monté de manière à pouvoir être commandé à partir du circuit de l'étançon 1 et de la pression de service dans la canalisation d'alimentation 10. (CF DESSIN DANS BOPI)The present invention relates to an additional clamping control device for pruning in underground mining operations, this device comprising a complementary clamping control valve placed in the pipe leading to the piston and an isolating member, operable. by hand, provided in a pipe connecting the high pressure fluid supply pipe and the additional tightening control valve. This device is characterized in that with the isolating member 3 is associated a switch 4 provided with a control piston which is mounted so as to be able to be controlled from the circuit of the prop 1 and from the pressure. service in supply line 10. (CF DRAWING IN BOPI)
