Definitions
- the invention relates to a method for installing a guide rail of an elevator installation.
- Elevator systems are usually arranged in a multi-storey elevator shaft.
- Such elevator systems include an elevator car and possibly a counterweight.
- the elevator car and the counterweight can be moved in opposite directions along the elevator shaft.
- Both the elevator car and the counterweight are guided on guide rails assigned to them.
- a guide rail comprises a plurality of aligned guide rail segments, which are aligned and fixed in succession in the elevator shaft during the installation of the guide rail.
- positioning jigs are inserted and fastened for this purpose both in a shaft trench of the elevator shaft and in a shaft head of the elevator shaft.
- Such positioning gauges include means for attaching, for example, straightening cords thereto.
- Such straightening straps are tensioned after installation along the elevator shaft and form an aid for aligning guide rail segments or guide rails.
- a first guide rail segment is fixed in the shaft pit and aligned on the basis of the guideline in the course of the installation of the guide rail.
- the alignment can be carried out by the first guide rail segment is spaced along its entire length at a fixed guide distance from the guideline, which means that the guide rail segment is arranged parallel to the guideline.
- further guide rail segments are lined up with the respectively previously aligned and fixed guide rail segment, aligned and fixed with the aid of the guide line.
- the orientation of the guide rail segment can be performed so that the guide rail segment is arranged as parallel as possible to the guideline.
- the elevator shaft may already have a different shape than the orientation of the second guide rail segment to be installed than was the case with the installation of the first guide rail segment. Consequently, the distance formed between the lower portion of the second guide rail segment and the guide line in the orientation of this second guide rail segment no longer corresponds to the guide distance. Even if each individual guide rail segment has been aligned parallel to the guideline, readjustments of the individual guide rail segments are therefore necessary with considerable expenditure of time.
- the object is achieved by a method for installing a guide rail of an elevator system arranged in an elevator shaft, wherein the guide rail comprises a plurality of aligned and aligned guide rail segments, the method comprising the following method steps: fixing a straightening element in the elevator shaft with respect to an aligned and fixed first the guide rail segments at a first point, wherein the first point is positioned on a track which distance is positioned by a horizontally directed parallel displacement of the track formed by the first guide rail segment, fixing the guide element at a second reference point in the elevator shaft such that between the first and second points are formed with a straightening element section for aligning a second of the guide rail segments, aligning the second guide rail segment relative to m straightening element section.
- the path formed by the first guide rail segment extends definitively along the guide section of the first guide rail segment.
- a reference point identifies one of the locations in the elevator shaft which can already be determined prior to the installation of the guide rail segments in the elevator shaft, usually within the shaft head or the shaft pit. Thus, the reference point can be determined immediately at the beginning of the installation of the entire guide rail. The position of the reference point is thus independent of the later deformations of the elevator shaft due to external influences.
- the reference point which can be maintained during the entire installation of all guide rail segments of the guide rail, is predetermined by the intended from the beginning of the installation target position of the top guide rail segment of the guide rail to be installed.
- the reference point on the one hand by that point in the shaft head / in the pit, at which point the guideway is intentionally aligned at the beginning of the installation, and on the other hand by the straightening distance of the guide element of this guideway is predetermined. If necessary, the reference point can be determined by means of a positioning gauge or another position-finding device. An alignment of the located in the immediate vicinity of the reference point guide rail segment on the basis of the directional distance to the straightening element thus leads to that located in the immediate vicinity of the reference point portion of this guide rail segment is positioned substantially properly in the elevator shaft.
- the invention is based on the finding that, as a result of the change in external influences, the elevator shaft may, if appropriate, fluctuate in the course of a single day or may be curved to a different extent.
- the external influences can cause a horizontal displacement of the shaft head by several centimeters. This effect occurs correspondingly increased in a comparatively high elevator shaft.
- Failure to observe such displacements results in the guide rail being aligned substantially non-parallel along the entire length of the guide element, which is designed to be an example of a guideline for aligning guide rail segments and fixed in the elevator shaft.
- a reorientation of the individual fastened guide rail segments, which has already been aligned with the guide element requires a great deal of time. In order to minimize these expenses, it was attempted to take into account the external influences already in the alignment of the individual guide rail segment directly after its alignment with the previously aligned and fixed guide rail segment.
- the fixation of the straightening element at the first point is made such that the
- Straightening element preferably in the immediate vicinity of the first point, a straightening distance to the first guide rail segment.
- the straightening element is fixed at the second point formed as a reference point. After an alignment of the second guide rail segment to the first aligned and fixed guide rail segment, the guide rail segment can be aligned parallel to the straightening element by means of the straightening distance. Stringing therefore means that the second guide rail segment is pre-fastened so that the guide sections of the two guide rail segments form a substantially shock-free guide track, this substantially shock-free guide track also remaining after the fixation of the second guide rail segment.
- Direction distance can be aligned, and also located in the immediate vicinity of the reference point guide rail segment is positioned substantially along a later finished aligned guideway in the elevator shaft. Accordingly, the effort for the readjustment of the guide rail can be largely reduced.
- the Richteiement is formed as a laser beam and the second point formed by a marker.
- the Richteiement can be designed as a guideline and attached to the second point by means of at least one fastening device in the elevator shaft. Such possibilities are given to shape the Richteiement.
- the guideline is stretched in the elevator shaft and in the first point a gripping device is arranged, which gripping device prevents an angle directed towards the course of the guideline movement of the guideline.
- the guideline installed and tensioned in the elevator shaft prior to the start of installation of the guide rail only has to be gripped and fixed along its pre-tensioned length before the alignment of a guide rail segment.
- the guideline can be stretched in advance by means of solder.
- the guideline can be stretched by means of two fastening devices before the installation of the guide rail segments at two different reference points in the elevator shaft, wherein one of these fastening device can be arranged at the second point formed as a reference point. This means that a first end of the guideline, which was fixed before the alignment of the now aligned guide rail segment, neither uninstalled and reinstalled again nor the guideline must be tightened again.
- Elevator shaft arranged.
- the second point may be arranged in a pit of the elevator shaft. According to these design variants, it is possible, the guide rail segments of the guide rail starting from
- the second point is determined by means of a reference device, which is preferably designed as a positioning gauge. In this way it is possible that the second point located in the elevator shaft before a fixation of the
- Straightening element can be located quickly at this point. Accordingly, an installation of the guide rail is accelerated by means of this method step.
- the first point is arranged on a second path, which second path has a length equal to half the length of the first guide rail segment, this second path being formed by a horizontally directed parallel displacement starting from one at the transition from the first to the second guide rail segment trained point of impact along the first Guide rail segment arranged distance is determined.
- the second guide rail segment is added to the first guide rail segment. It is advantageous that the straightening element is positioned with respect to the last aligned and fastened first guide rail segment and accordingly do not contribute to the misalignment of the second guide rail segment deformations of the elevator shaft, which occurred during installation of the first guide rail segment.
- the second guide rail segment is aligned parallel to the fixed guide element section. Such a simple way is given to align the second guide rail segment based on the straightening element.
