DETAILED DESCRIPTION OF THE INVENTION

Figures 1-7 show an example of a traction sheave so-called. a 1: 2 hanger elevator with lower drive room, where the traction sheave 3 with its driving means 8 20 is located at the lower end of the elevator shaft 13 in a separate engine room on the side of the elevator shaft 13. In the following, in the description of the method and apparatus, the invention · *** · will be described in connection with the elevator of Figures 1-7, whereby ···. , ·, But not limited to. The methods of the invention · ··· ···, 2 5 are equally useful, whether it is a lower or • * “upper machine room elevator or a non-machine elevator elevator,” where the elevator drive mechanism is located in the elevator shaft.

The invention is also not limited to any particular method of suspension. Thus, the invention is advantageously applicable to ·: '·· 30 1: 2, 1: 4 etc. as well as to 1: 1 • · · suspended hangers. Further, the invention is suitable for use also in non-counterweight lifts. Further, the following describes the changeover operation of a single rope, although one elevator normally has 3 to 12 adjacent ropes. The ropes are shifted one by one and the same operations are performed 9 118645 sequentially for each rope. Within the basic idea of the invention, it is also possible to change more than one rope at the same time, thereby speeding up the changeover. By changing all the ropes of the elevator 5 in one pull, the pulleys are free to rotate and thus do not oppose the rope movement. In this case, the support of the body and the counterweight in the shaft must necessarily be independent of the elevator rope, for example by supporting the counterweight by the bumper 10 or otherwise from the bottom of the shaft and secured by guides or separate temporary fastening to the rails.

Figure 1 shows an elevator in which the elevator is in its normal operating mode and ready to replace the old rope 4. The old rope 4 is fastened at both ends to a fixed superstructure 5, which here is the roof of the elevator shaft 13. Between the mounts, the old rope 4 is guided over the folding wheels 2 in the elevator car 6 and counterweight 7 and the drive wheel 3 rotatable by the drive 8. In the elevator of Figure 1, there are two diverting wheels 2 at the top of the shaft or above it, two • diverting wheels at the bottom of the shaft • · ·, elevator car 6 • m ** ·; 'has two diverting wheels 2 and one counterweight • · · * ·! topwheel 2. When replacing, the new rope is supposed to get • • · the same route as the old rope.

With reference to Figure 1, as the replacement of the old rope * · * den 4 begins, the elevator car is raised so that the roof 14 of his-30 casket 6 is substantially in the same plane. ·. with top floor level 15.

As shown in Figure 2, the counterweight 7 is placed under the counterweight 7 to support the counterweight 7 to maintain it. . ·. 35 in place when the support for rope 4 is removed. The elevator car • · · is lifted by means of a hoist or other hoisting means 42 • * ** 'up to 10 cm, e.g. 30 cm, upwards and the 10 118645 elevator car 6 is locked in its guides. In this case, the old rope 4 of the elevator is loosened so that it no longer has the tensile load caused by the counterweight and the elevator car.

3 shows that three lightening devices 10 are mounted on the circumference of the drive wheel 3, whereby the old rope 4 is lifted out of contact with the rope groove 9 of the drive wheel 3 so that the old rope 4 can be slid during movement by the support 10 of the lightening devices 10. Lightening devices 10 are required on the drive wheel 3, since the drive wheel 3, unlike the pulleys 2, is not freely rotatable. The structure of the lightening device 10 is described in more detail with reference to Figures 8 and 9.

The extension member 11 is described in more detail with reference to Figures 10 and 11. .

*. . ·. 35 The other end of the old rope 4, from which the rope assembly 1, · · · 4 is to be pulled by the rope pulling device 12, is a tap with air-conditioning tape, etc. and cut off at 11 118645. This retractable end is fed to the rope pulling device 12.

Fig. 6 shows a situation in which the rope pulling device 12 has been operated until the old rope 4 has been pulled out around all the pulleys 2 and the drive wheel 3 and the new rope 1 is completely threaded around them. The old rope 4, which is still suspended by means of the extension connection member 11 and closed at the end of the new passage 1, is guided to the bottom of the elevator shaft 13. The freely downwardly suspended rope portion has counteracted the rope pull by lightening the draw. The jointing member 11 has passed through the rope pulling device 12.

The rope pulling device 12 is preferably provided with a torque limiter which limits the pulling force so that the pulling rope does not raise the counterweight 7 from the support 16, which could cause a hazard.

When the jointing member 11 has passed through the rope pulling device 12 as shown in Figure 6, the rope pulling device 12 is stopped. The old rope 4 is secured to the elevator railing • · * • t · or other ropes and the new rope 1 still attached thereto is taped next to the jointing member 11 and • · * * ·! · * 25 is cut at the taping with a rope cutter .

The bracket 19 is releasably and adjustably supported on the clamp jaws 18. The rope 1 and / or 4 separated from the rope groove 9 of the traction sheave 3 can be guided from the bracket 19. The lightening device 10 further includes a skip guard 20 which is removably and adjustably supported on the clamp jaws 18 at a slightly greater distance from the bracket 19 of the connector member 11 so that the gap 10 between the carrier 19 and the jumper guard 20 allows the ropes 1, 4 and connector member 11 to pass. The lightening device 10 of Figure 9 simultaneously supports all parallel ropes. The distance between the jaws 18 of the compression 20 is adjustable so that the lightening device 10 can be mounted on different widths of the drive wheels 13.

Figures 10 and 11 show a splice member 11 for end-to-end connection of the old rope 4 • · · 25 and the new rope 1.
