Abstract

A method and a mounting device for carrying out an installation operation in an elevator shaft of an elevator system include introducing a first elongate reference element into the elevator shaft oriented in a main direction of extent of the elevator shaft. The mounting device is introduced into the elevator shaft, which mounting device has a carrier component and a mechatronic installation component held by the carrier component. The mounting device is displaced into a fixing position in the main direction of extent of the elevator shaft. The relative position of the carrier component of the mounting device is determined with respect to the first reference element in the fixing position with a sensor arranged on the installation component. The relative position of the first reference element is determined with respect to at least two different sensor positions and thus positions of the installation component.

First claim

The invention claimed is:

1. A method for performing an installation operation in an elevator shaft of an elevator system comprising the following steps:
introducing an elongate first reference element into the elevator shaft, the first reference element being oriented in a main extension direction of the elevator shaft;
introducing a mounting device into the elevator shaft, the mounting device including a carrier component and a mechatronic installation component that is held by the carrier component;
displacing the mounting device in the main extension direction into a fixing position in the elevator shaft;
determining a relative position of the carrier component, in the fixing position, with respect to the first reference element using a sensor arranged on the installation component, the relative position being determined with respect to at least two different sensor positions of the sensor corresponding to two different positions of the installation component mutually spaced in the main extension direction;
determining the fixing position of the mounting device in the elevator shaft based on the relative position of the carrier component of the mounting device with respect to the first reference element;
determining a mounting position of a mounting step to be carried out by the installation component; and
carrying out the mounting step.

2. The method according to claim 1 wherein the sensor is fixed on the installation component.

3. The method according to claim 1 including using a signal generated by an acceleration sensor arranged on the mounting device to determine the fixing position.

4. The method according to claim 1 including introducing an elongate second reference element into the elevator shaft, the second reference element being oriented in the main extension direction of the elevator shaft, and determining a relative position of the mounting device, in the fixing position, with respect to the second reference element using the sensor arranged on the installation component.

5. The method according to claim 4 wherein the installation component is held by the carrier component by a retaining device, and a relative position of the retaining device with respect to at least one of the first reference element and the second reference element is determined.

6. The method according to claim 1 wherein the installation component is held by the carrier component by a retaining device, and a relative position of the retaining device with respect to the first reference element is determined.

7. The method according to claim 1 including, in order to set the fixing position, fixing the carrier component directly to at least one wall of the elevator shaft.

8. The method according to claim 1 including, in order to set the fixing position, press-fitting the carrier component directly to walls of the elevator shaft.

9. The method according to claim 1 including introducing an elongate second reference element into the elevator shaft, the second reference element being oriented in the main extension direction of the elevator shaft, fastening a first mounting plate in the elevator shaft, and fastening first ends of the first and second reference elements to the first mounting plate.

10. The method according to claim 9 including fastening a second mounting plate in the elevator shaft and fastening second ends of the first and second reference elements to the second mounting plate.

11. The method according to claim 1 including fixing ends of the first reference element to the elevator shaft to reduce oscillations of the first reference element.

12. The method according to claim 1 including introducing an elongate second reference element into the elevator shaft, the second reference element being oriented in the main extension direction of the elevator shaft, and fixing ends of the second reference element to the elevator shaft to reduce oscillations of the second reference element.

13. A mounting device for carrying out an installation operation in an elevator shaft of an elevator system comprising:
a carrier component and a mechatronic installation component held by the carrier component, the carrier component being displaceable in a main extension direction of the elevator shaft and adapted to be selectively fixed in a fixing position in the elevator shaft;
an electronic control for determining a relative position of the mounting device, in the fixing position, with respect to an elongate first reference element in the elevator shaft, the first reference element being oriented in the main extension direction, using a sensor arranged on the installation component;
wherein the electronic control determines a relative position of the first reference element with respect to at least two different sensor positions of the sensor corresponding to two different positions of the installation component mutually spaced in the main extension direction; and
determining the fixing position in the elevator shaft based upon the relative position of the mounting device with respect to the first reference element.
