Abstract

The object of the invention is an installation arrangement for an elevator in an elevator hoistway, which installation arrangement comprises at least a suspension member aligned downwards from the top part of the elevator hoistway, in connection with which suspension member is, at least during the installation of the elevator car, an installation hoist arranged to move while supported by the suspension member, and in which installation arrangement at least the guide rails of the elevator and the elevator car traveling guided by the guide rails are installed in the elevator hoistway. An auxiliary hoist provided with a hoisting means is fitted onto the suspension member, which auxiliary hoist is arranged to move reciprocally in the vertical direction along the suspension member.

First claim

The invention claimed is:

1. An installation arrangement for an elevator in an elevator hoistway, the installation arrangement comprising:
at least a suspension member suspended downwards from a top of the elevator hoistway;
an installation hoist configured to perform a first movement to move in the elevator hoistway along the suspension member while supported by the suspension member above an elevator car, the installation hoist configured to hoist at least the elevator car traveling on guide rails in the elevator hoistway in response to the first movement of the installation hoist along the suspension member; and
an auxiliary hoist including a hoisting member supported by the suspension member between a roof of the elevator hoistway and the installation hoist such that the auxiliary hoist is above the elevator car, the auxiliary hoist configured to perform a second movement to move reciprocally in the elevator hoistway along the suspension member independently of the first movement of the installation hoist along the suspension member.

2. The installation arrangement according to claim 1 , wherein
a first traction sheave associated with the installation hoist is configured to rotationally move to perform the first movement to move the installation hoist along the suspension member, and
a second traction sheave associated with the auxiliary hoist is configured to rotationally move to perform the second movement to move the auxiliary hoist along the suspension member such that the installation hoist and the auxiliary hoist move along a same suspension member.

3. The installation arrangement according to claim 2 , wherein a cross-section of the suspension member is V-shaped on a contact surface on the first traction sheave and the second traction sheave.

4. The installation arrangement according to claim 2 , wherein outer rims of the first traction sheave and the second traction sheave are configured to correspond to the suspension member.

5. The installation arrangement according to claim 1 , wherein the suspension member is a toothed belt having teeth thereon.

6. The installation arrangement according to claim 5 , wherein the teeth are one of (i) transverse and straight; (ii) transverse and curved; (iii) inclined in one direction; (iv) inclined in two directions; and (v) V-shaped.

7. The Installation arrangement according to claim 1 , wherein the auxiliary hoist is configured to move on the suspension member in relation to the installation hoist.

8. The Installation arrangement according to claim 1 , wherein the hoisting member of the auxiliary hoist is adjustable in length or is replaceable.

9. The installation arrangement of claim 1 , wherein the auxiliary hoist is configured to selectively disconnect from the suspension member by sliding the auxiliary hoist in a direction perpendicular to a length of the suspension member when there is a sufficient gap between a traction sheave associated with the auxiliary hoist and the suspension member.

10. The installation arrangement of claim 1 , wherein
the suspension member is configured to attach to a fixing point on the roof of the elevator hoistway.

11. An auxiliary hoist comprising:
a motor configured to perform a first movement to move the auxiliary hoist in an elevator hoistway along a toothed belt, the toothed belt configured to support an installation hoist attached thereto below the auxiliary hoist in the elevator hoistway such that the auxiliary hoist is above an elevator car between a roof of the elevator hoistway and the installation hoist, the installation hoist configured to perform a second movement to move in the elevator hoistway along the toothed belt to move an elevator car along a first section of guide rails installed in the elevator hoistway such that the auxiliary hoist is configured to perform the first movement along the toothed belt independently of the second movement of the installation hoist along the toothed belt; and
a hoisting member connected to a frame of the auxiliary hoist, the hoisting member configured to lift a second section of the guide rails within the elevator hoistway.

12. The auxiliary hoist of claim 11 , further comprising:
a traction sheave having V-shaped grooves therein corresponding to teeth of the toothed belt.

13. The auxiliary hoist of claim 11 , wherein the auxiliary hoist is configured to selectively disconnect from the toothed belt by sliding the auxiliary hoist in a direction perpendicular to a length of the toothed belt when there is a sufficient gap between a traction sheave associated with the auxiliary hoist and the toothed belt.

14. The auxiliary hoist of claim 11 , further comprising:
a controller configured to instruct the motor to move the auxiliary hoist along the toothed belt.

15. The auxiliary hoist of claim 11 , wherein the installation hoist is installed one of above the elevator car or inside the elevator car.

16. The auxiliary hoist of claim 11 , wherein, the auxiliary hoist is configured to hoist the second section of the guide rails within the elevator hoistway without locking the elevator car and detaching the toothed belt from the elevator car.

17. An auxiliary hoist comprising:
a motor configured to move the auxiliary hoist along a toothed belt, the toothed belt configured to support an installation hoist attached thereto between the auxiliary hoist and an elevator car in an elevator hoistway, the installation hoist configured to move the elevator car along a first section of guide rails installed in the elevator hoistway; and
a hoisting member connected to a frame of the auxiliary hoist, the hoisting member configured to lift a second section of the guide rails within the elevator hoistway, wherein
an end of the toothed belt is configured to attach to a fixing point on the roof of the elevator hoistway.
