Truss crane track inspection method based on three-dimensional scanner technology

Abstract

The invention discloses a truss crane rail inspection method based on a three-dimensional scanner technology. The method comprises the following steps: selecting three or more control reference pointson a cylinder, measuring coordinates of the control reference point in a construction coordinate system; erecting a scanner, and scanning the position of the truss crane rail; converting the scanningdata into a construction coordinate system; selecting the scanning data of the truss crane and independently storing the scanning data as scanning data of the truss crane, cutting out the section ofthe track beam every 2m, extracting three-dimensional coordinates of points on the two sides of the section, comparing coordinates and elevation difference values of the same positions of track points, obtaining the actual distance and elevation difference of the track gauge, and obtaining a deviation value is obtained through comparison of the theoretical distance and the actual distance. According to the method, an accurate detection result can be obtained, so a basis is provided for inspection and acceptance of the truss crane rail, the problem of inspection of the truss crane rail in construction is solved, the inspection safety of the truss crane rail at high altitude is improved, the detection is flexible, the measurement is convenient, and the quality control requirement of field construction is met.

Description

technical field [0001] The invention belongs to the field of civil construction, and in particular relates to a method for inspecting a truss suspension track based on a three-dimensional scanner technology. Background technique [0002] There are generally many truss cranes in industrial plant equipment. As an important equipment for hoisting and hoisting, truss cranes have always been paid attention to during their installation and use. During the use of truss cranes, frequent inspections are required and there are many measurements. However, truss cranes are generally installed at higher heights. Due to limited construction site conditions, scaffolding needs to be erected during inspection. Even if more safety measures are invested, its safety performance It is still not easy to guarantee, resulting in a long inspection time, which is not conducive to the optimization of the construction period and cannot ensure the quality of work. SUMMARY OF THE INVENTION [0003] Th...

Problems solved by technology

The truss crane needs frequent inspections and more measurements during its use, and the truss crane is generally installed at a higher position. Due to the limited conditions of the general construction site, scaffolding needs to be erected during the inspection. Even if more safety measures are put in, its safety performance It is still not easy to ensure that it takes a long time to check, which is not conducive to the optimization of the construction period and cannot ensure the quality of work
