Abstract

In a method for carrying out an installation process in an elevator shaft of an elevator system, an assembly device is inserted into the elevator shaft. The assembly device includes a support component, a mechatronic installation component retained by the support component and a control apparatus. At least one assembly apparatus (tool, sensor or component) is arranged on the support component. The support component is fixed in a fixing position in the elevator shaft. After the support component has been fixed, an actual position of the at least one assembly apparatus is determined relative to the installation component. Using the determined actual position relative to the support component, the at least one assembly apparatus is received by the installation component and an assembly step is carried out using the received at least one assembly apparatus.

First claim

The invention claimed is:

1. A method for carrying out an installation process in an elevator shaft of an elevator system comprising the steps of:
inserting an assembly device into the elevator shaft, the assembly device including a support component, an installation component being a mechatronic installation component that is retained by the support component, a control apparatus for controlling the installation component, and an assembly means arranged on the support component;
fixing the support component in a fixing position in the elevator shaft;
determining an actual position of the assembly means relative to the installation component based on an initial position of the assembly means stored in the control apparatus and based on a deformation of the support component brought about by the fixing in the fixing position;
receiving the assembly means by the installation component using the actual position of the assembly means; and
carrying out an assembly step with the installation component using the received assembly means.

2. The method according to claim 1 including at least two magazines arranged on the support component for retaining the assembly means and a plurality of additional assembly means and determining an actual position of each of the assembly means in the magazines.

3. The method according to claim 1 including identifying the deformation of the support component from an actual position of at least one reference point of the support component measured by a sensor when the support component is in the fixing position and an initial position of the at least one reference point before the fixing of the support component, the initial position being stored in the control apparatus.

4. The method according to claim 3 including measuring the actual position of the at least one reference point contactlessly.

5. The method according to claim 3 including arranging the sensor on the installation component before the support component is fixed.

6. The method according to claim 5 wherein the sensor is rigidly arranged on the installation component.

7. The method according to claim 1 including arranging at least one deformation sensor on the support component for measuring a magnitude of the deformation of the support component.

8. The method according to claim 7 including measuring stresses in the support component by the at least one deformation sensor, and determining the deformation of the support component from the measured stresses.

9. An assembly device for carrying out an installation process in an elevator shaft of an elevator system comprising:
a support component;
an installation component being a mechatronic installation component retained on the support component; and
a control apparatus for determining an actual position of an assembly means, arranged on the support component, relative to the installation component based on an initial position of the assembly means stored in the control apparatus and a deformation of the support component brought about by a fixing of the support component in a fixing position in the elevator shaft, and the control means actuating the installation component using the actual position of the assembly means to receive the assembly means and carry out an assembly step using the received assembly means.

10. The assembly device according to claim 9 including a sensor rigidly arranged on the installation component for measuring the actual position based on a reference point on the support component.

11. The assembly device according to claim 9 including at least one deformation sensor arranged on the support component for measuring a magnitude of the deformation of the support component.

12. The assembly device according to claim 11 wherein the at least one deformation sensor is adapted to measure stresses in the support component, and wherein the control apparatus determines the deformation of the support component from the measured stresses.

13. A method for carrying out an installation process in an elevator shaft of an elevator system comprising the steps of:
inserting an assembly device into the elevator shaft, the assembly device including a support component, an installation component being a mechatronic installation component that is retained by the support component, a control apparatus for controlling the installation component, and an assembly means arranged on the support component;
fixing the support component in a fixing position in the elevator shaft;
determining an actual position of the assembly means relative to the installation component, wherein the installation component is retained by the support component by a retaining device, and the actual position of the assembly means is determined relative to the retaining device;
receiving the assembly means by the installation component using the actual position of the assembly means; and
carrying out an assembly step with the installation component using the received assembly means.
