Lift facility, belt for such a lift facility, method for manufacturing such a belt, combination of such a belt and method for assembling such a combination in a lift facility

Abstract

A lift belt (12) for a lift installation comprises a belt body (15) in which a tensile carrier arrangement (14) with several tensile carriers (14.1, 14.2) for transmission of a tension force in longitudinal direction of the lift belt is arranged. A profile body (16) which spaces these tensile carriers from one another is arranged between adjacent tensile carriers (14.1, 14.2) of the tensile carrier arrangement (14). <SDOCL LA=EN> 12 Claims 1. Lift belt (12) for a lift installation, with a belt body (15) in which a tensile carrier arrangement (14) with several tensile carriers (14.1, 14.2) in the form of strands or cables for transmission of a tension force in longitudinal direction of the lift be lt is arranged, characterised in that a profile body (16) is arranged between adjacent tensi le carriers (14.1, 14.2) of the tensile carrier arrangement (14) and spaces these tensil e carriers from one another. 2. Lift belt according to claim 1, characterised in that a respective profil e body (16) is arranged between several, preferably between all, tensile carriers of the tensile carrier arrangement (14). 3. Lift belt according to claim 2, characterised in that all profile bodies (16) have the same cross-sectional shape. 4. Lift belt according to claim 2, characterised in that at least two profil e bodies (16) have different cross-sectional shapes. 5. Lift belt according to any one of the preceding claims, characterised in that a profile body has a substantially circular, oval (16.1), T-shaped, double-T-shaped (16.3), U- shaped, triangular or quadrangular (16.2) cross-section. 6. Lift belt according to any one of the preceding claims, characterised in that a profile body extends in longitudinal direction ofthe lift belt (12), particularly substantially over the entire lengthof the lift belt. 7.

Description

Technical field [0001] The present invention relates to an elevator installation with a belt, a belt used in such an elevator installation, a method of manufacturing such a belt, and to an assembly of the belt and the assembly of the assembly in the elevator installation Methods. Background technique [0002] The elevator equipment includes an elevator car movable along an elevator shaft or along a free-standing guide rail and a usual counterweight. In order to generate movement, the elevator equipment has at least one drive device, has at least one drive pulley or drive shaft, and uses one or more belts to support the elevator car and the counterweight, and / or transmit the required driving force to Above. [0003] In that case, using the same belt, the elevator car and counterweight can be connected to the drive device. Optionally, the elevator car and the counterweight can also be connected to the driving device using separate belts, so that when the elevator car descends, the ...

Problems solved by technology

On the other hand, in the case of excessively sharp wedge angles, it can occur that the belt jams in the groove of the pulley

As a stick-slip effect, this jamming excites the belt to generate undesired vibrations, which at the same time generate noise and increase the dynamic load of the belt and the risk of running off its guide rails

In this extreme case, this jamming can also lead to failure of the elevator system if the belt only jumps out of the groove of the pulley or does not leave the groove of the pulley at all.
