DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a procedure and to an apparatus for installing an elevator.
DESCRIPTION OF THE BACKGROUND ART
The installation of an elevator is a critical stage in a building project. The elevator must be available for use as early as possible during the construction period. It is desirable that the elevator should function at this stage in the same way as it will in a finished building, and e.g. the safety equipment must be in operation. On the other hand, the elevator should be installed as quickly as possible without causing disturbances in other construction work. Special installations intended for the installation and construction period should be kept to a minimum and the elevator should be directly installed in its final form to avoid the need for later adjustments and trimming. The elevator must be installed quickly and economically. Additional features to the standard requirements are encountered in the installation of an elevator without machine room, in which all the shaft equipment must be mainly installed in the shaft space.
SUMMARY OF THE INVENTION
The object of the present invention is to create a new and economical solution for the installation of an elevator.
According to the invention, during the installation of the elevator the overspeed governor is at least in the vertical direction so adjusted that it corresponds to the final placement of the overspeed governor and after the elevator installation the overspeed governor is detached from the suspension element and fixed in its final mounting point. An element for supporting the overspeed governor is fitted to a suspension element. Further, the overspeed governor is preferably mounted on the suspension element and its position at least in the vertical direction is adjusted to the final position of installation of the overspeed governor and the overspeed governor ropes are adjusted substantially to their final length. The overspeed governor can be utilised during elevator installation and its final installation is easy to carry out and requires no rope length adjustment.
By using the solution of the invention, the shaft equipment for an elevator can be installed quickly and reliably. Installation-time overspeed governor installation can be done from the top floor landing. As the overspeed governor is now operational, work safety in elevator installation is substantially improved.
Further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.
BRIEF DESCRIPTION OF THE DRAWINGS
In the following, the invention will be described by the aid of a few of its embodiments by referring to the drawings which are given by way of illustration only, and thus are not limitative or the present invention, and in which
FIG. 1 presents an elevator shaft before the elevator is installed,
FIG. 2 presents the upper part of the shaft when the overspeed governor is being mounted,
FIG. 3 presents a means for mounting the overspeed governor, and
FIG. 4 presents the upper part of the shaft with the installation finished.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 1 shows a cross-section of the elevator shaft 2 before installation of the elevator. The shaft comprises a back wall 4 and front wall 6 with door openings 8 at the landings 10 and 11, and side walls 12. Fixed to the shaft ceiling 14 are suspension elements, such as suspension loops 16, 17 and 19, to be used in the installation. There are three suspension loops fixed to the shaft ceiling, of which the first suspension loop 16 is used to mount a hoisting device, the second suspension loop 17 is used for temporary installation of the overspeed
