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

摘要

In an emergency brake for guided special conveyors comprising trains of differing composition in underground mining roadways, especially in a brake trolley for an overhead monorail conveyor with a friction brake, which produces a braking force resulting in a given minimum deceleration of the train, and with a speedometer device which senses the track speed and at a predetermined track speed actuates a brake release device, it is proposed according to the invention that an inclinometer (2) sensing the track incline ( alpha ) be provided, which in downhill and uphill travel reduces the track speed necessary for actuation of the brake release device and in level to rising travel increases it and in addition reduces the braking force from a maximum value for maximum train weight and greatest track incline in uphill and downhill running to the lowest value for minimal track inclines or level roadways and maximum train weight, according to the track incline measured at any time (Fig. 10). <IMAGE>
