A dynamic detection device and implementation method for shape and position parameters of elevator guide rails

Abstract

The invention discloses a dynamic detection device for shape and position parameters of an elevator guide rail, which includes a detector and a mechanical fixing bracket for installing the detector on the elevator guide rail. The hardware of the detector includes a laser, a two-dimensional position sensitive device, a PSD Signal amplification conversion circuit, A / D conversion module, Hall distance measuring sensor, ARM9 chip, liquid crystal display LCD and PC; the mechanical fixing bracket includes an adjustable longitudinal support arm connected to the upper beam of the car, and the The upper end of the adjustable longitudinal support arm is connected with an adjustable horizontal support arm, and the adjustable horizontal support arm is connected with a guide rail tester chassis for installing a tester through a fixed slide rail and a sliding shoe on the side of the guide rail, and the guide rail tester chassis A U-shaped guide rail detector chassis clamping arm is connected to the outer periphery of the guide rail detector chassis, and the front side of the guide rail detector chassis clamping arm is provided with two guide rail side clamping rollers that are respectively located on the two sides of the elevator guide rail. The invention has simple, firm and reliable mechanical structure, clear and simple circuit connection relationship of the detector, and can effectively meet the requirement of detection accuracy.

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 ...
