A method for constructing an elevator system with adjustable usable lift height

Abstract

A method for constructing an elevator system (1) in a building with an elevator drive (4), an elevator car (5), a counterweight (6) and at least one flexible carrier (7) , wherein at least one lifting operation is performed in order to adapt the available lifting height (15) of the elevator system (1) to the increasing height of the building. The drive platform (16), which carries the elevator drive machine (4) and via the carrying mechanism (7) the elevator car (5) and the counterweight (6), is raised during the lifting operation. In the method, the carrier means (7) are essentially compensated by at least one compensating traction means (36) leading from the underside of the elevator car (5) via a deflection device (35) to the underside of the counterweight (6) The weight of the elevator car side bearing mechanism (F A ) and the weight of the bearing mechanism on the counterweight side (F G ), wherein the steering device (35) comprises two roller structures (45, 49) each having at least one steering roller (41, 42, 43, 44; 41, 42, 43, 44, 70, 71, 72, 73), wherein said at least one compensating traction mechanism (36) is respectively guided on at least one diverting roller of two roller structures (45, 49), so that it forms at least one compensating traction mechanism ring (40) in which a predetermined amount of compensating traction means (36) is stored and wherein the distance between the two roller structures (45, 49) is reduced before and / or during the lifting operation such that The amount of compensating traction mechanism (36) required to perform the lifting operation is released from at least one compensating traction mechanism ring (40).

Description

technical field [0001] The invention relates to a method for building an elevator system in which at least one lifting operation is performed in order to adapt the available lifting height of the elevator system to the increasing height of a building, and to an elevator system built according to such a method. Background technique [0002] Before an elevator system can work in its normal working manner, it can already be installed in a building during the construction phase. The elevator system can then be used already during the construction phase for the vertical transport of people or materials, wherein the lift height available for the elevator system can be adapted to its current height during construction of the building and thus grows with the building. As a result, a separate external elevator, for example placed on the outside of the building, can be completely or partially dispensed with. [0003] For example, if several lower floors of the building have been buil...

AI Technical Summary

Problems solved by technology

[0007] Both elevator systems have the considerable disadvantage that the traction mechanism clamping device acts on the traction mechanism area, which then acts as a load-carrying mechanism or compensating traction mechanism which is loaded and runs via the cable drum
