Device and method for dynamically detecting shape-position parameters of elevator guide rail

Abstract

The invention discloses a device for dynamically detecting shape-position parameters of an elevator guide rail. The device comprises a detector, and a mechanical fixed support for positioning the detector on the elevator guide rail; the hardware of the detector includes a laser, a 2D position sensitive device, a PSD signal amplifying conversion circuit, an A / D conversion module, a hall ranging sensor, an ARM9 chip, an LCD and a PC; the mechanical fixed support comprises an adjustable longitudinal supporting arm which is connected to an upper cross beam of a car; an adjustable horizontal supporting arm is connected to the upper end of the adjustable longitudinal supporting arm and is connected with a guide rail detector chassis for positioning the detector through a slide rail and slid shoots fixed on the side surface of the guide rail; a U-shaped guide rail detector chassis clamping arm is connected to the periphery of the guide rail detector chassis; two guide rail side surface clamping rollers which are respectively positioned on two side surfaces of the elevator guide rail are arranged at the front side of the guide rail detector chassis clamping arm. The device is simple in mechanical arm, firm, reliable, clear and simple in connection relationship of a detector circuit, and effectively meets the requirement on detection precision.

Description

technical field [0001] The invention relates to a dynamic detection device for shape and position parameters of an elevator guide rail and a realization method, and belongs to the technical field of inspection and detection of special equipment. Background technique [0002] At present, none of the elevator guide rail verticality testing instruments used at home and abroad adopts the corresponding mechanical fixing mechanism, and its data receiving devices are all implemented manually, so the stability is poor, and the measured data error is large; It is stipulated that the verticality embedded detection system of the elevator guide rail needs to measure the change of the small displacement, that is, at least within the range of 0.1mm, so the sensitivity of the selected detector must be high. In order to achieve the above-mentioned detection accuracy and mechanical structure fixing requirements, it is the research of the present invention Object. Contents of the invention ...
