Problems solved by technology

The problem with adjusting at intervals is that the traction member may be at the wrong tension for a long time between adjustments
This is especially problematic in elevators with large travel heights (where the elongation is relatively long)

Embodiment Construction

[0015] An elevator installation achievable by means of the arrangement according to the invention comprises at least an elevator car 1 adapted for reciprocating movement in an elevator shaft and at least one or more compensating weights 2, said elevator car 1 and compensating weights 2 As such is connected to support the elevator car 1 by means of suspension members 4, such as belts or ropes, and also by means of diverting pulleys 6 and 7 (eg mounted on bearings at the top of the elevator shaft). Whenever only one compensating weight is mentioned hereinafter, it is intended to mean simultaneously one or more compensating weights, or alternatively one or more counterweights. Furthermore, the device according to the invention also comprises a traction machine 3 provided with at least one traction sheave 3a or corresponding means and located in a machine station arranged at the bottom of the elevator shaft; and at least one or more traction members 5, such as belts or ropes, adap...

Abstract

The object of the present invention is a device for adjusting the tension of the traction members of an elevator, which device comprises: an elevator car (1) and a compensation weight (2), an elevator car (1) and a compensation weight ( 2) connected for its part to support the elevator car (1) by means of suspension members (4) such as ropes or belts; and the traction machine (3) with traction sheave (3a); and a traction member (5), such as a belt, adapted to convert the rotational motion of the traction sheave (3a) into motion of the elevator car (1) and compensating weight (2); and a tension control device (8), arranged to The magnitude of the tension applied to the suspension member (4) and the traction member is adjusted. The device comprises a tensioning device (9) connected to the traction member (5), and a tension control device (8) is connected to the part of the traction member (5) on the side of the compensating weight (2) relative to the traction pulley (3a) , and the tensioning device (9) is connected to the part of the traction member (5) on the side of the elevator car (1) relative to the traction sheave (3a).

Description

technical field [0001] The object of the invention is a device for adjusting the tension of an elevator traction member as defined in the preamble of claim 1 . Background technique [0002] In some elevator installations, the suspension members of the elevator car, such as suspension ropes, and the traction members of the elevator car are separated from each other. Usually, in this case, for practical reasons, the traction machine is arranged on the floor of the elevator shaft or close to the bottom of the elevator shaft, and for example toothed belts or other belts suitable for the purpose can be used as traction means , these traction members are mounted below the elevator car and one or more compensating or counterweights. In elevators of this type, the stresses exerted on the suspension members and traction members vary inter alia with changes in the load in the elevator car. From the viewpoint of normal operation of the elevator, it is desired that the stress distribu...
