Problems solved by technology

[0004] A disadvantage of the safety braking device described above is that, when the masses to be braked are different, different delay values ​​of the carrier will result
When the load in the carrier is very high, this results in a particularly small delay of the carrier and when the load is small this leads to an impermissibly high delay of the carrier and thus damage to persons and property

Embodiment Construction

[0016] As shown in FIGS. 1 and 2, 1 designates the casing fastened to the support means of the vertical conveyor, not shown in the figures, and 2 designates the guide rails 2 of the elevator. The brake wedges 3 and 4 are arranged on both sides of the guide rail 2 in the casing 1 . Brake wedges 3 , 4 are supported in housing 1 via bearing shoes 5 , 6 and spring elements 7 , 8 , wherein bearing shoes 5 , 6 and spring elements 7 , 8 are guided in grooves 9 , 10 in housing 1 . Arranged above the brake wedges 3 , 4 is a stop 11 which is guided in the housing 1 and moves back and forth in the direction indicated by the double arrow 12 . For this purpose, an adjusting device 13 is provided, which is operatively connected to the stop and with which the stop 11 is positioned according to the mass to be braked. The mass mainly includes the load existing in the carrying device, the weight of the car and the real-time effective weight component of the tail cable suspended below the carry...

Abstract

The invention relates to a brake arresting device comprising at least one brake wedge (3, 4) which is arranged in a housing. Said brake wedge acts on a guide rail (2) of the load suspension means when a braking procedure is triggered, and the course thereof is limited by means of a stop. The inventive device enables definite deceleration to occur during braking, independently from the size of the load in the load suspension means. To this end, at least one regulating device (13, 14) is provided which is actively connected to at least one stop (11, 15) or the housing (1). The stop (11, 15) or the housing (1) is automatically positioned by means of the regulating device (13, 14) before the beginning of each course in such a way that in the event of safety braking, the compression of at least one spring element (7, 8) and therefore the resulting spring force by means of which the spring element (7, 8) presses the brake wedge (3, 4) against the guide rail, are adapted to the actual mass to be slowed down.

Description

technical field [0001] The invention relates to a safety braking device for a carrier of vertical conveying equipment, comprising at least one braking wedge, which is arranged in a casing and which acts when starting the braking process On the guide rail of the conveying car, and a stop, which limits the travel of at least one brake wedge and thus limits the maximum braking force during the braking process. In addition, the present invention also relates to a method for adapting the braking force of the safety braking device of the carrying device of the vertical conveying equipment to the mass of the carrying device during safety braking. Background technique [0002] Such safety braking devices are used, for example, in the cages of passenger elevators, freight elevators and mine conveyors, where the braking process is usually initiated by the limiting cables of the overspeed governor acting on the brake wedges when the permissible operating speed is exceeded. [0003] In...
