Emergency brake for guided special conveyors comprising trains of differing composition in underground mining roadways, especially braked trolleys for overhead monorails

摘要

In an emergency brake for guided special conveyors comprising trains of differing composition in underground mining roadways, especially braked trolleys for overhead monorails with a friction brake, which generates a braking force producing a predetermined minimum deceleration of the train and a speedometer device, which senses the track speed and at a predetermined track speed actuates a brake releasing device, it is proposed according to the invention that an inclinometer (2), detecting the track inclination (@) be provided, which in downhill travel reduces the track speed necessary for actuation of the brake release device and in horizontal to ascending travel increases this and in addition reduces the braking force from a highest value for maximum train weight and greatest track inclination in downhill travel to the lowest value for the smallest track inclinations in downhill travel and with maximum train weight according to the track inclination measured at any one time (Fig.10).
