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

[0032] figure 1 The elevator 1 shown includes an elevator car 2, a counterweight 3, and an elevator suspension steel cable 11. The elevator suspension steel cable 11 tractions the elevator car 2 and the counterweight 3, as well as a traction pulley 5 and a reversing pulley 15, which operate through the suspension steel Cable 11 is passed to elevator car 2 and counterweight 3. The suspension ratio of the elevator car 2 is 1:1, and the suspension ratio of the counterweight 3 is 2:1. In this scheme, the compensation steel cable 4 is passed from the elevator car 2 through the reversing pulley 6 installed on the bottom layer, and then through the reversing pulley 7 in the counterweight 3 to reach the tension load 8 connected to the end of the cable. on. The tension load can move vertically when the cables 4 and 11 extend. In the present invention, the suspension ratio of the compensation cable is the same as the suspension ratio of the suspension cable, that is, 1:1 on the elevator c...

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 case is 94105271.0, the name of the invention is compensation wire rope device, and the filing date is April 5, 1994. Technical field [0002] The invention relates to a compensation steel cable device in an elevator and a device for compensating the extension of the elevator steel cable. Background technique [0003] In elevators with large hoisting heights, compensation cables are required to balance the unstable torque generated by the hoisting cables when the elevator is running. Without this balance, the motor has to be designed to be quite large, and its effect becomes worse as the height increases. If the shaft height is greatly increased without compensation, then there will be insufficient friction. High-rise elevators use compensating steel cables that are tensioned to compensate for the tensioning weight. [0004] In high-rise buildings, the elevator runs at high spee...
