Abstract

A method and arrangement for automatic elevator installation includes marking each door opening in the elevator shaft with door reflectors, and creating a reference coordinate system of the elevator shaft with a robotic total station positioned at a bottom of the elevator shaft, measuring the position of the door reflectors with the robotic total station, fitting straight door lines to the measurements in order to form virtual plumb lines for the doors in the elevator shaft, marking predetermined guide rail positions on the bottom of the elevator shaft and installing lowermost guide rails manually to the shaft based on the guide rail positions, forming vertical guide rail lines, i.e. virtual plumb lines for the guide rails with the robotic total station based on the door lines, providing an upwards and downwards movable installation platform in the elevator shaft provided with platform reflectors, and measuring the position of the platform reflectors with the robotic total station, whereby the orientation and the position of the installation platform in relation to the elevator shaft can be determined.

Claims15

Dependent claims

An arrangement for automatic elevator installation, comprising:

downwards facing door reflectors, each door opening in an elevator shaft being marked with the downwards facing door reflectors positioned at opposite sides of the door opening;
a robotic total station positioned at a bottom of the elevator shaft, whereby a reference coordinate system of the elevator shaft is created with the robotic total station, the position of the door reflectors in relation to the elevator shaft being measured with the robotic total station such that measurements thereof are provided;
and
straight door lines fitted to the measurements, said straight door lines forming virtual plumb lines for doors in the elevator shaft;
wherein predetermined positions of the guide rails on the bottom of the elevator shaft are marked based on dimensions of the elevator shaft and an elevator car,
wherein lowermost guide rails are installed manually to the elevator shaft based on the predetermined positions of the guide rails,
wherein vertical guide rail lines are formed with the robotic total station based on the door lines, said vertical guide rail lines forming virtual plumb lines for the guide rails in the elevator shaft,
wherein an upwards and downwards movable installation platform is provided in the elevator shaft,
wherein downwards facing platform reflectors are positioned on a bottom of the installation platform, and
wherein a position of the platform reflectors is measured in relation to the elevator shaft with the robotic total station, whereby an orientation and the position of the installation platform in relation to the elevator shaft is determined.
