Device and method of guide rail straightness measuring

Abstract

The invention discloses a device and a method of a guide rail straightness measuring. The device of the guide rail straightness measuring comprises displacement sensor installation arms, a data acquisition system, a slide platform and an upper computer control system, wherein each array of the displacement sensor installation arms are provided with a plurality of displacement sensor assemblies which are arranged at the roughly same intervals, and sensor measuring faces are basically in the same plane. Compared with the background technology of a guide rail straightness measuring device, scan guide rails do not need to be additionally and specially arranged, and the existing lift car and the traction system are only needed to be borrowed. The length of each measured guide rail is not limited, three faces of a single guide rail can be respectively measured, and spatial position relationship between two guide rails can be measured. By adopting the guide rail straightness measuring device, guide rail straightness and the spatial position relationship of the guide rails can be on-position high-accurately measured, the device and the method of the guide rail straightness measuring particularly has no limit on the length of each installed measured lift guide rail and is suitable for measuring the installed lift guide rails.

Description

technical field [0001] The invention relates to a method for measuring the straightness of guide rails, which is especially suitable for measuring the straightness of installed elevator guide rails, and the lifting height of the elevator has no influence on the measurement results, and at the same time, the distance between two guide rails can be measured. Relative angular position relationship. Background technique [0002] At present, the straightness measurement of guide rail basically has the following technologies: [0003] One is a reference measurement, and the other is a non-reference measurement. According to the query related patents, there are the following related technologies: [0004] 1. Patent number: CN200810051009.X. [0005] A method for dynamically measuring the straightness of guide rails. The technical solutions are as follows: 1. An optical measurement platform should be equipped; The reflector moves along the guide rail synchronously with the slide...

AI Technical Summary

Problems solved by technology

[0008] The above-mentioned background technology 1 is a measurement technology with a reference, which needs to be specially designed for scanning guide rails, which is difficult to realize in on-site measurement; the background technology 2 is a measurement without a reference, but a display screen with the same length as the measured range needs to be installed, and the cost is relatively high. complex

Most of the current straightness measurement technologies for guide rails are based on the measurement technology with reference, which is complicated to implement, and some non-reference measurement technologies are also difficult to implement due to the length limitation of the measured guide rail.
