Steel structure warping degree detection device

Abstract

A steel structure warping degree detection device comprises a light source vehicle, a detection vehicle and a handheld terminal, and the light source vehicle achieves position adjustment of a light source through a transverse adjusting motor and a longitudinal adjusting motor and automatically aligns to the bull's-eye of a measurement target; both the light source vehicle and the detection vehicleadopt a steering crawling mode with independent driving on two sides to realize direction adjustment; the detection vehicle adopts a light spot position automatic detection technology and a precisionlinear motor dragging technology, the detection precision is improved to 0.1 mm from 0.5 mm measured by a steel ruler, the light spot height can be dynamically tracked, and the light spot detection range is expanded; the detection vehicle can automatically track laser beams in the whole process, automatically correct deviation tracks and actively avoid obstacles when approaching the obstacles; and the detection vehicle and the handheld terminal can be in wireless communication.

Description

technical field [0001] The invention relates to the technical field of safety status evaluation of hoisting machinery. Background technique [0002] The safety status evaluation of large-scale hoisting machinery will gradually become one of the important tasks of public welfare inspection and testing institutions, which puts forward higher requirements for the personnel and inspection and testing methods of inspection and testing institutions. The focus of the evaluation of the safety status of large-scale hoisting machinery is the evaluation of the stability of the whole machine, and the most important index for its evaluation is the bending value of the main beam in the horizontal direction. The national standards "Universal Bridge Cranes" (GB / T14405), "Universal Gantry Cranes" (GB / T14406), and "Conditions for Scrapping Foundry Cranes" (GB / T36697) apply to the main girders of newly manufactured or in-use bridge gantry cranes. Bends in the horizontal direction are specifie...

Problems solved by technology

[0003] According to relevant information at home and abroad, the current method of measuring the stability of the main girder of the crane still uses the traditional method, and the current measurement method of the bending value of the main girder in the horizontal direction still generally adopts the manual measurement method. This measurement method has the following problems: (1) Detection accuracy Low; (2) The test results are greatly affected by humans; (3) The physical condition and physical strength of the inspectors are high; (4) The personal safety of the inspectors is difficult to be guaranteed; (5) The inspection efficiency is low, etc.

[0004] This method cannot meet the requirements of manufacturing, use and testing, especially the testing of equipment in use.

The intelligent measurement of the stability of the main girder is imperative. At present, there is no such instrument and equipment at home and abroad. Therefore, a steel structure warpage detection device for the horizontal bending value of the main girder of the crane will fill the gap at home and abroad.
