Problems solved by technology

It's a pity that in these solutions there is no compensation system, that's why in these solutions a large electric motor has to be used, also the height is limited due to friction

Embodiment Construction

[0024] figure 1 Shown elevator 1 comprises elevator car 2, counterweight 3 and elevator suspension cable 11, and elevator suspension cable 11 pulls elevator car 2 and counterweight 3, and traction pulley 5 and reversing pulley 15, and their operation passes suspension steel Cable 11 is transmitted to elevator car 2 and counterweight 3. The suspension ratio of elevator car 2 is 1:1, and the suspension ratio of counterweight 3 is 2:1. In this solution, the compensating cable 4 passes from the elevator car 2 through the reversing pulley 6 installed on the ground floor, and then passes through the reversing pulley 7 in the counterweight 3 to reach the tension load 8 connected to the end of the cable superior. This tension load is able to move vertically when the cables 4 and 11 are extended. In the present invention, the suspension ratio of the compensating cables is the same as that of the suspension cables, that is, 1:1 on the elevator car side and 2:1 on the counterweight si...

Abstract

In an elevator system comprising an elevator car, a counterweight, a set of elevator suspension ropes on which the elevator car and the counterweight are suspended, a traction sheave whose motion is transmitted via the suspension ropes to the elevator car and to the counterweight, a compensating system includes a set of compensating ropes connected to the elevator car and the counterweight via at least one diverting pulley. A vertically adjustable buffer arrangement mounted in conjunction with the counterweight allows the system to compensate for changes in the length of the suspension and compensating ropes. The suspension ratio of the compensating ropes is an integer multiple of the suspension ratio of the suspension ropes. Finally, the rope suspension ratio on the side of the elevator car can be the same as that of the counterweight, or it may be different.

Description

[0001] This application is a divisional application, the application number of the corresponding parent application is 94105271.0, the title of the invention is compensation cable device, and the application date is April 5, 1994. technical field [0002] The invention relates to a compensating cable arrangement in an elevator, and a device for compensating the extension of the elevator cable. Background technique [0003] In elevators with large hoisting heights, compensating cables are required to balance the unstable moments generated by the hoisting cables during operation of the elevator. Without this balance, the motor would have to be designed to be quite large, becoming less effective with height. Insufficient friction will occur if the shaft height is greatly increased without compensation. High-rise elevators use compensating cables that are tensioned due to compensating tensioned weight. [0004] In high-rise buildings, where the elevator is running at high spee...
