Embodiment Construction

[0042] The elevator installation 1 is formed from at least one elevator car 2 and an elevator drive 10 . Such as figure 1 The elevator installation 1 shown as an example additionally requires a carrier mechanism 11 and a counterweight 12, wherein the elevator drive 10 drives the carrier mechanism 11 and thereby drives the elevator car 2 and the counterweight 12 in opposite directions. to move. The elevator installation 1 requires at least one braking device 13 . The braking device 13 holds the stopped elevator car 2, for example during loading on the floor 6, or in an emergency situation the braking device 13 brakes the elevator car 2, for example, on an unexpected opening of a floor passage, Or for the elevator car 2 running too fast, for example, safety braking is performed when the bearing mechanism 11 fails. Different load situations require different braking or holding forces F B .

[0043] FIG. 2 shows a further braking device 13, which consists of a brake control u...

Abstract

To provide adjustable braking equipment capable of delaying or holding according to the operating state of an elevator installation and responding in a quick and gentle mode, and to provide a method for braking and holding an elevator cage. The elevator installation is provided with the elevator cage vertically moving within guide tracks 9. The braking equipment 13 comprises at least two brake units 14. Each brake unit is provided with a normal force regulator 16 setting a normal force FNcorresponding to a normal force value determined by a brake control unit 15, and / or the brake unit comprises a locking device which locks the brake unit into a set braking position and preferably maintains the set braking position. This solution permits a gentle braking or holding of the elevator cage in low energy requirement.

Description

technical field [0001] The invention relates to an elevator installation with a braking device and to a method for braking and stopping an elevator installation. Background technique [0002] The elevator installation includes an elevator car which moves in the vertical direction within the guide rails. When necessary, the elevator car is braked or kept at a stop by the braking device. A braking force is required to hold or brake the elevator car. For this purpose, the brake device usually uses at least two brake units, which optionally press at least one brake lining against a mating surface. The pressing is achieved with a vertical force. The braking force of a brake lining is determined by the vertical force combined with the coefficient of friction defined by the lining, mating surface and any intermediate layers. The opposing force is usually determined by the guideway face or guideway. [0003] DE3934492 discloses a braking device for an elevator car, which is com...
