Description

The invention relates to an adjustment device for adjusting a guide rail in an elevator system, comprising at least one elevator shaft, the adjustment device comprising at least one plumb bob, at least one frame, which frame comprises a first segment for application to the guide rail and a second segment arranged perpendicular to the first segment , a first measuring scale for detecting a position of the guide rail with respect to the at least one solder in at least a first spatial direction, the first measuring scale being arranged on the second segment of the frame, and a second measuring scale for detecting a position of the guide rail with respect to the at least one solder in at least one second spatial direction.

The invention further relates to a method for adjusting a guide rail in an elevator system and an elevator system.

As a rule, a guide rail is pre-assembled in an elevator shaft and then adjusted. As a rule, a solder is used, which is stretched vertically in the elevator shaft and which serves as a reference for the adjustment of the guide rail.

In practice, a guide rail in an elevator shaft is usually adjusted by using a measuring device to measure the distance between the plumb line and the guide rail in two spatial directions, comparing the measured distance with reference values and then the position if the measured values deviate from the reference values the guide rail is corrected based on the measured values.

This measuring method is very susceptible to errors, in particular since with this measuring method the solder is easily deflected out of its original position when the measuring device is applied to the solder, and it can thus result in falsified measured values being read.

The JP 2018 280 A discloses an alternative adjustment method in which a frame is applied to the guide rail, the frame for determining the position of the guide rail with respect to the solder having a first viewing window with a first measuring scale in a first spatial direction and a second viewing window with a second in a second spatial direction Has measuring scale, the solder being illuminated for better reading of the measured value.

The problem with the adjustment device known from the prior art is that the viewing windows each having a measuring scale are spaced apart from the solder. For this reason, this measurement method is very susceptible to errors, since an accurate measurement value can only be read if the measurement value is read at a certain angle.

Against this background, it is an object of the present invention to improve an initially mentioned adjustment device and to provide an improved adjustment method. In particular, the adjustment device should have an inexpensive construction. In particular, the adjustment device should be easy to handle and in particular be operated by only one person.

To achieve this object, an adjustment device, an adjustment method and an elevator system according to the independent claims are proposed. Further advantageous embodiments of the invention are described in the dependent claims and the description and are shown in the exemplary embodiments shown in the figures.

The proposed solution provides an adjustment device for adjusting a guide rail in an elevator installation, comprising at least one elevator shaft. The adjustment device comprises a solder, at least one frame, a first measuring scale for detecting a position of the guide rail with respect to the at least one solder in a first spatial direction and a second measuring scale for detecting a position of the guide rail with respect to the at least one solder in a second Spatial direction. In particular, the guide rail comprises a plurality of guide rail segments. In particular, the guide rail is arranged vertically in the elevator shaft. In particular, the guide rail is arranged horizontally in the elevator shaft; in particular, the solder is stretched horizontally in the elevator shaft in this case. In particular, the adjustment device can also be used to adjust other elevator components that can be adjusted by means of a tensioned plumb bob as a reference.

The frame of the adjustment device comprises a first segment for contacting the guide rail and a second segment arranged perpendicular to the first segment, on which the first measuring scale is arranged. In particular, the first measuring scale is arranged in the direction of extent of the second segment.

The adjustment device further comprises a stop angle, a current source and a signal transmitter. In particular, the signal transmitter is set up to provide an optical and / or acoustic signal output when the stop angle is in contact with the solder.

In one embodiment of the invention, the current source is in electrical connection with the signal transmitter, the stop angle and the solder in such a way that an open circuit is formed. In particular, the current source is integrated in the signal generator. In particular, the signal transmitter is connected to the solder with a first cable connection. In particular, the signal transmitter is connected to the stop bracket with a second cable connection. In particular, the circuit between the solder and the stop angle is interrupted.

The power source, the signal generator, the stop angle and the solder are in electrical connection such that the circuit is closed when the stop angle and the solder are in contact. In particular, the circuit is closed when the stop angle is in direct contact with the solder.

The stop bracket includes a first arm and a second arm. In one embodiment of the invention, the second measuring scale is arranged on the second arm of the stop angle. In particular, the second measuring scale is arranged along the direction of extension of the second arm of the stop angle.

In a further embodiment of the invention, an insulating material is arranged on the first arm of the stop bracket. In particular, the insulating material prevents electrical contact between the stop angle and the second segment of the frame during the measurement process. In particular, the first arm of the stop angle has a projection which enables the stop angle to be applied precisely in order to measure the guide rail position with respect to the solder. In particular, the projection arranged on the first arm of the stop bracket has an insulating material in order to prevent electrical contact with the second segment of the frame during the measurement process.

In order to adjust a guide rail in an elevator shaft of an elevator installation, the guide rail is first pre-assembled in the elevator shaft.

To adjust the guide rail pre-assembled in the elevator shaft by means of the adjustment device according to the invention, a solder is first tensioned in the direction of the extension of the guide rail to be adjusted in the elevator shaft in the immediate vicinity of the guide rail to be adjusted.

In order to determine the position of the guide rail with respect to the solder in a first spatial direction and in a second spatial direction, a signal transmitter is used which emits an optical and / or acoustic signal. In this way, sources of error are to be reduced when acquiring the measured values for determining the position of the guide rail.

To determine the position of the guide rail with respect to the solder, the frame of the adjustment device is placed flush with the guide rail with its first segment in the direction of extension of the guide rail. In particular, the frame is placed with its first segment on the guide rail in such a way that the second segment of the frame arranged perpendicular to the first segment points in the direction of the solder. In particular, the frame is fastened to the guide rail to be adjusted with a fastening means. In particular, the first segment of the frame is attached to the guide rail to be adjusted. In particular, the fastening means is a clip and / or a screw clamp and / or a magnet. In particular, the fastening means is firmly connected to the frame for easier handling.

A current source is electrically connected to the signal generator so that the signal generator can emit an optical and / or acoustic signal. In particular, the current source is integrated in the signal generator.

In a further process step, the signal transmitter is electrically connected to the solder and the stop angle, so that an open circuit is formed. In particular, the signal transmitter is electrically connected to the solder with a first cable connection. In particular, the signal generator is electrically connected to the stop bracket with a second cable connection.

In a further method step, a first arm of the stop angle is applied to the second segment of the frame. In particular, the first arm of the stop bracket has a projection arranged perpendicular to the first arm, by means of which the stop bracket is placed flush against the second segment of the frame.

The stop angle is then shifted along the second segment of the frame in the direction of the solder until the second arm of the stop angle arranged perpendicular to the first arm comes into contact with the solder and the circuit is thus closed, so that the signal transmitter emits an optical and / or acoustic signal . In particular, the projection arranged on the first arm of the stop bracket remains with the Moving the stop angle along the second segment of the frame in permanent contact with the second segment of the frame. In particular, the first arm of the stop bracket has an insulating material. In particular, an electrical contact between the stop bracket and the frame is prevented by means of the insulating material.

If the circuit is closed by a contact of the second arm of the stop angle with the solder, so that the signal transmitter emits an optical and / or acoustic signal, the position of the guide rail with respect to the solder in the first spatial direction is determined using the first measuring scale, which is on the second segment of the Frame is arranged, measured and measured in the second spatial direction by means of the second measuring scale, which is arranged on the second arm of the stop angle.

In particular, the first measuring scale is arranged in the direction of extension of the second segment of the frame and the second measuring scale is arranged in the direction of extension of the second arm of the stop angle. In particular, the point at which the solder is in contact with the second arm of the stop angle on the second measuring scale marks the measured value for the position of the guide rail with respect to the solder in the second spatial direction. In particular, the second arm of the stop angle on the second segment of the frame marks the value to be read on the first measuring scale for the position of the guide rail with respect to the plumb in the first spatial direction.

The measured values for the position of the guide rail with respect to the solder in the first spatial direction measured by means of the first measuring scale and the position of the guide rail with respect to the solder in the second spatial direction measured with the second measuring scale are compared with reference values.

If the value measured by means of the first measuring scale and / or second measuring scale deviates from the corresponding reference value, the position of the guide rail in the first spatial direction and / or in the second spatial direction is corrected based on the value measured using the first measuring scale and / or second measuring scale.

These method steps are carried out in the order described above until the position of the guide rail measured by means of the first measuring scale and the second measuring scale matches the reference values in the first spatial direction and the second spatial direction.

By means of the adjustment device according to the invention and the adjustment method according to the invention, it is possible to detect the position of the guide rail with respect to the solder in the first spatial direction and the second spatial direction with millimeter precision.

Advantageously, the adjustment device according to the invention and the adjustment method according to the invention have the advantage over the known prior art that the position of the guide rail with respect to the solder can be read very precisely by means of the first measurement scale and the second measurement scale. It is not necessary to determine the measured value by reading the measuring scale from a certain angle.

Furthermore, the emitting of the optical and / or acoustic signal by the signal transmitter when the stop angle touches the solder prevents the position of the solder from being changed by the measuring device. In this way, the measurement accuracy is greatly improved.
