Embodiment Construction

[0029] The specific examples provided in the description given below should not be construed as limiting the scope and / or applicability of the appended claims. The lists and example sets provided in the description given below are not exhaustive unless expressly stated otherwise.

[0030] figure 1 An example of an elevator brake 100 is schematically shown in which embodiments of the invention can be implemented. The elevator brake 100 comprises a frame part 102 , a moving armature 106 and a brake pad 108 with a friction lining 109 . Moving the armature 106 through the guide pins ( figure 1 Not shown in ) is movably supported on the frame member 102.

[0031] The elevator brake 100 also comprises at least one energy store, such as a working spring, ie a thrust spring 110 a , 100 b arranged between the armature 106 and the frame part 102 . Furthermore, the frame part 102 includes at least one electromagnet 104 configured to resist the braking force generated by the plurality...

Abstract

The invention relates to an elevator brake (100) comprising: a frame part (102) comprising an electromagnet (104); a moving armature (106) movably supported on the frame part (102); at least one energy storage, such as a work spring (110a, 1Ob), arranged between the frame part (102) and the moving armature (106); a friction lining (109) associated with the moving armature (106) and fitted to engage a braking surface (107) with a normal force originating from the at least one energy storage (1Oa, 100b), to brake movement of an elevator car or to hold the elevator car standstill; and a sensor system comprising one or more sensors (302a-302d) mounted into the elevator brake (100) and adapted to sense one or more operational parameters of the elevator brake (100) and / or to directly measure normal force of the friction lining (109).

Description

technical field [0001] The present invention generally relates to the technical field of elevators. In particular, the invention relates to a solution for monitoring the operation of elevator brakes. Background technique [0002] Typically, elevators have multiple electromagnetic brakes (usually two brakes) to brake the movement of the elevator car. The elevator brake can be implemented as a hoisting mechanical brake, which is mounted on the elevator machine and the brake acts on the traction sheave or the rotating shaft of the machine to brake the movement of the traction sheave and thus the elevator car. Alternatively, the brake can be implemented as an elevator car brake which is mounted on the elevator car and which acts on the guide rails to directly brake the movement of the elevator car. Typically, an elevator brake includes a brake frame and an armature movably supported on the brake frame. In addition, the brake frame includes an electromagnet that resists a brak...
