Abstract

The object of the invention is an arrangement and a guide rail bracket for fixing the compensating weight guide rails of an elevator.

First claim

The invention claimed is:

1. An elevator arrangement comprising:
an elevator car configured to move reciprocally along a guide rail;
at least one compensating weight configured to support the elevator car by at least one suspension rope and at least one diverting pulley, the at least one compensating weight being guided by compensating weight guide rails; and
a hoisting machine including a traction sheave and at least one traction rope configured to transfer rotational movement of the traction sheave into movement of the elevator car and movement of the at least one compensating weight, wherein
the compensating weight guide rails are fixed in place with guide rail brackets and are configured to extend vertically, the guide rail brackets including fixing parts for the compensating weight guide rails and for the guide rail, and
the compensating weight guide rails include a spring element in an extension point of the compensating weight guide rails, the spring element configured to function as an aligning support element.

2. The elevator arrangement according to claim 1 , wherein
the fixing parts include fixing holes; and
a shape and dimensions of the guide rail brackets and manufacturing tolerances, positions, and dimensions of the fixing holes are configured such that the guide rail brackets determine a positioning location of the compensating weight guide rails, when the guide rail brackets are fixed to the guide rail.

3. The elevator arrangement according to claim 2 , wherein the positioning location of the compensating weight guide rails is set without a separate plumbing or alignment of the compensating weight guide rails.

4. The elevator arrangement according to claim 1 , wherein a location of the compensating weight guide rails with respect to the guide rail and a distance between the compensating weight guide rails are configured to be determined by a shape, dimensions, fixing holes and manufacturing tolerances of the guide rail brackets, and wherein the fixing holes are configured in accordance with a guide rail line of the guide rail.

5. The elevator arrangement according claim 1 , further comprising:
at least one wall bracket configured to fix a first end of at least one of the guide rail brackets to a fixing point in a hoistway of the elevator car, a second end of the at least one of the guide rail brackets being fixed to the guide rail, the compensating weight guide rails being fixed in the hoistway via the guide rail brackets such that the at least one compensating weight is configured to move in the hoistway.

6. The elevator arrangement according claim 1 , further comprising:
a cover plate fixed to at least two guide rail brackets, the guide rail brackets being consecutive in a vertical direction.

7. The elevator arrangement according claim 1 , wherein the compensating weight guide rails include a lower compensating weight guide rail and an upper compensating weight guide rail arranged consecutively in a vertical direction from a bottom of a hoistway, and wherein a top end of the lower compensating weight guide rail and a bottom end of the upper compensating weight guide rail are configured to be fixed on the same guide rail bracket in an extension point of the compensating weight guide rails.

8. The elevator arrangement according claim 1 , wherein the compensating weight guide rails include elongated fixing holes at fixed intervals, the compensating weight guide rails being configured to be cut through the center point of the elongated fixing holes for finding a correct point for an extension of the compensating weight guide rails with the guide rail brackets.

9. A guide rail bracket for fixing the compensating weight guide rails of an elevator, the guide rail bracket comprising:
a first fixing-parts for fixing two separate compensating weight guide rails in place, each of the two separate compensating weight guide rails including a spring element in an extension point of respective ones of the two separate compensating weight guide rails, the spring element configured to function as an aligning support element; and
a second fixing-parts for fixing a guide rail of the elevator.

10. The guide rail bracket according to claim 9 , wherein a final positioning location of both the guide rail and the compensating weight guide rails are ready in the same guide rail bracket.

11. The guide rail bracket according to claim 9 , wherein both the first fixing-parts and second fixing-parts include a plurality of fixing holes, and wherein a shape and dimensions of the guide rail bracket and manufacturing tolerances, positions, and dimensions of the plurality of fixing holes are configured such that a final positioning location of the compensating weight guide rails is ready in the guide rail bracket, the final positioning location being with respect to the guide rail, and the guide rail bracket being fixed to the guide rail.

12. The guide rail bracket according to claim 9 , wherein a first end and a second end of the guide rail bracket include fixing holes for fixing the guide rail bracket to the guide rail and to a position in an elevator hoistway.

13. A guide rail bracket of an elevator comprising:
a first end configured to fix a guide rail of the elevator in place;
a second end configured to fix the guide rail bracket to a position in a hoistway of the elevator; and
a portion between the first end and second end, the portion being configured to fix at least two separate compensating weight guide rails in place such that the at least two separate compensating weight guide rails each extend vertically in the hoistway, the at least two separate compensating weight guide rails each including a spring element in an extension point of respective ones of the two separate compensating weight guide rails, the spring element configured to function as an aligning support element.

14. The guide rail bracket according to claim 13 , wherein the guide rail bracket includes a plurality of fixing holes for fixing the compensating weight guide rails and the guide rail bracket.

15. The guide rail bracket according to claim 14 , wherein a shape and dimensions of the guide rail bracket and manufacturing tolerances, positions, and dimensions of the plurality of fixing holes are configured such that a final positioning location of the at least two separate compensating weight guide rails is ready in the guide rail bracket, the final positioning location being with respect to the guide rail, and the guide rail bracket being fixed to the guide rail.

16. The guide rail bracket according claim 13 , wherein the spring element is configured to function as an aligning support element for an extension of the compensating weight guide rails and the guide rail bracket.
