Abstract

A pipeline binocular three-dimensional measuring device disclosed by the invention comprises a routing inspection holder, a three-dimensional routing inspection mechanism, an abutting seat assembly and a balance idle wheel assembly, the routing inspection holder comprises an arc-shaped sleeve rod and a telescopic arc rod, one end of the telescopic arc rod is slidably sleeved in the arc-shaped sleeve rod, a driving motor is fixedly installed on the outer side of the arc-shaped sleeve rod, a rack is arranged on one side of the telescopic arc rod, the output end of the driving motor is fixedly sleeved with driving teeth meshed with the surface of the rack, and a moving rotating wheel is fixedly installed on the inner side of the arc-shaped sleeve rod. According to the invention, an automatic rack structure is adopted, an inspection retainer is used for wrapping and clamping an oil and gas pipeline, the movement inspection of the three-dimensional inspection mechanism is realized through the clamping movement of a movement rotating wheel and an abutting seat assembly on the pipeline, the three-dimensional identification scanning of the periphery of the pipeline is automatically carried out, the inspection difficulty of the oil and gas pipeline is reduced, the position structure is flexibly adjusted, and three-dimensional measurement of the morphology of the pipeline is realized.

Description

technical field [0001] The invention relates to the technical field of pipeline inspection, in particular to a binocular three-dimensional measurement device for pipelines. Background technique [0002] Due to the damage of various external forces and the corrosion of humid air in the daily use of pipelines, open-air pipelines often deform and sag, thus causing oil and gas leakage, causing huge economic losses and environmental pollution. Cracks and blockages caused by aging pipelines require regular maintenance. Due to the limitations of the inner diameter of the pipeline and the internal and external environment, it is usually necessary to rely on pipeline robots for inspection and maintenance. However, due to the variety of pipeline sizes and setting environments, it is unrealistic to design different pipeline robots for each size and type of pipeline according to its inspection requirements. In this case, it is necessary to repair the damaged part of the pipeline. Befo...

Problems solved by technology

[0003] The existing 3D modeling of pipelines mainly adopts the method of manual inspection. The inspectors hold the pole to move the 3D sampling head, scan and record the 3D image of the outer wall of the pipeline through the 3D sampling head, and automatically identify the outer wall of the pipeline through image processing. The regular and standardized training of inspection personnel and the allocation of inspection personnel under special environmental operations also increase the cost of the enterprise, and petrochemical plants are prone to safety hazards due to the unstable chemical properties of their production and transportation products. Oil and gas pipelines are mainly arranged in Manual inspection at high places is difficult and inconvenient to operate

[0004] In addition, although the existing driving structure is installed during the inspection process in the length direction of the pipeline, because the peripheral size of the pipeline is not constant and single, for example, there will be a pipeline connector at a fixed length, so that the smoothness of the outer wall of the pipeline is irregular , thus causing obstacles to the movement of the inspection structure on the pipeline, and even requiring repeated shutdowns for manual movement and crossing

[0005] In view of this, the existing problems are studied and improved, and a binocular three-dimensional measurement device for pipelines is provided to solve the existing problems of difficult pipeline inspection and low labor efficiency. The purpose of improving practical value
