Embodiment Construction

[0041] figure 1 A general view of the elevator installation 1 is shown. An elevator installation 1 is installed in a building for transporting people or goods within the building. The elevator installation comprises an elevator car 2 which can be moved up and down along guide rails 6 . For this purpose, the elevator car 2 is provided with guide shoes 8 which guide the elevator car as precisely as possible along a predetermined travel path. The elevator car 2 is accessible from the building by means of a door. The drive 5 serves to drive and hold the elevator car 2 . The drive device 5 is arranged, for example, in the upper area of ​​the building, at which the car 2 is suspended by a support device 4 , such as a support cable or a support belt. The support device 4 is guided forwards to the counterweight 3 by means of the drive device 5 . The counterweight balances the mass proportions of the elevator car 2 so that the drive 5 only essentially has to provide compensation f...

Abstract

The invention relates to an elevator system having an elevator car (2) displaceably disposed along at least two guide rails (6), and the elevator car (2) has a brake system having preferably two elevator brakes (20). The elevator brake device (20) includes a brake housing (21) and an energy accumulator (24). The brake housing (21) is mounted in a vertically displaceable manner, or such that it can be displaced in a longitudinal direction and in parallel relative to a brake direction between a first position (B1) and a second position (B2). The energy accumulator (24) acts upon the brake housing (21) and displaces the brake housing in the direction of a second position (B2). The elevator brake device (20) further comprises an actuator (32) that can act upon the brake housing (21) and is designed to retain the brake housing in a first position (B1). In its first position (P1), the actuator can retain the brake housing (21) in the first position (B1) against the force (F24) of the energy accumulator (24). In its second position (P2), the actuator allows displacing the brake housing (21) into the second position (B2). In this way, a brake element (25) is brought into contact with the brake rail (7).

Description

technical field [0001] The invention relates to a braking device with an actuating device for braking an elevator car, a method for operating the braking device and an elevator installation with such a braking device. Background technique [0002] Elevator equipment is installed in buildings. It mainly consists of a car connected to a counterweight or a second car by means of support means. The car is moved along substantially vertical guide rails by means of drive means which act selectively on the support means or directly on the car or the counterweight. Elevator installations are used in buildings to transport people and goods between single or multiple floors. The elevator installation includes a device for securing the elevator car in the event of a failure of the drive or the supporting device. For this purpose, braking devices are usually used which are able to brake the elevator car on the guide rails when required. [0003] Such a braking device is known from p...
