Abstract

The current disclosure relates to a guide rail alignment method comprising attaching and aligning a first pair of elevator car guide rail sections in an elevator shaft and mounting a vertically moveable base between the guide rail sections. After the first pair of elevator car guide rail sections has been aligned, a target member comprising a target point is removably attached to a guide rail section, and a positioning light source able to produce a beam of collimated light is attached to the vertically moveable base, so that a beam of collimated light emitted in a predetermined direction by the positioning light source meets the target point of the target member. The position of the light source is then used to align a guide rail section of a second pair of guide rail sections. The current disclosure further relates to an elevator guide rail alignment arrangement.

First claim

The invention claimed is:

1. A guide rail alignment method, comprising:
attaching and aligning a first pair of elevator car guide rail sections in an elevator shaft;
mounting a vertically moveable base between the first pair of elevator guide rail sections, the vertically moveable base being one of an elevator car sling, an elevator car or a working platform configured to support a installation personnel within the elevator shaft;
removably attaching a first target member to a respective one of the first pair of elevator guide rail sections after the first pair of elevator car guide rail sections has been aligned, the first target member including a first target point;
removably attaching a positioning light source to the vertically moveable base such that the positioning light source is supported by the one of the elevator car sling, the elevator car or the working platform with a beam of collimated light emitted by the positioning light source meeting the first target point;
attaching a second pair of guide rail sections in the elevator shaft;
removably attaching a second target member having a second target point to a respective one of the second pair of guide rail sections such that the second target point is at a same position in a horizontal direction as the first target point; and
aligning the second pair of guide rail sections so that the beam produced by the positioning light source meets the second target point.

2. The method according to claim 1 , wherein the removably attaching the positioning light source includes removably attaching the positioning light source to the vertically moveable base such that the beam of collimated light is emitted in a vertical direction.

3. The method according to claim 1 , wherein the first target member is attached to the respective one of the first pair of elevator guide rail sections above the vertically moveable base.

4. The method according to claim 1 , wherein the positioning light source includes a pair of positioning light sources each attached to the vertically moveable base,
the removably attaching the first target member includes removably attaching a pair of first target members to respective ones of the first pair of elevator guide rail sections, the pair of first target member each including first target points, and
the removably attaching the positioning light source includes removably attaching the pair of positioning light sources to the vertically moveable base such that beams emitted by the pair of positioning light sources meet respective ones of the first target points allowing simultaneous alignment of both of the first pair of elevator guide rail sections.

5. The method according to claim 1 , wherein the positioning light source is positioned on a bottom of the vertically moveable base.

6. The method according to claim 1 , wherein the vertically moveable base comprises a top structure, the top structure having an opening therein to allow passage of the beam through the top structure.

7. The method according to claim 1 , wherein the second target member is attached to an upper end of the respective one of the second pair of elevator guide rail sections.

8. The method according to claim 1 , wherein movement of the vertically moveable base is limited in the horizontal direction to 0.5-1.0 mm.

9. The method according to claim 1 , wherein after the second pair of guide rail sections has been attached and aligned, at least one further pair of guide rail sections is attached and aligned in the same manner as the second pair of guide rail sections, and wherein the positioning light source remains in the same position during attaching and aligning of at least one further pair of guide rail sections.

10. The method according to claim 1 , wherein the positioning light source is supported by the elevator car sling vertically movable within the elevator shaft.

11. The method according to claim 1 , wherein the positioning light source is supported by the elevator car vertically movable within the elevator shaft.

12. The method according to claim 1 , wherein the positioning light source is supported by the working platform vertically movable within the elevator shaft and configured to support the installation personnel within the elevator shaft.
