Embodiment Construction

[0016] A preferred embodiment of the present invention is: see Figure 1 and figure 2 , the online real-time ultrasonic thickness measuring device for multi-caliber pipelines, including multi-channel ultrasonic probes 2 that are uniformly distributed along the circumference of the pipeline 1 and radially facing each other in pairs, and a water spray mechanism that forms the water-immersion focused ultrasonic probe 2, is characterized in that The ultrasonic probe 2 and the nozzle 11 of the water spray mechanism are connected with a linkage radial position adjustment mechanism to coordinately adjust the radial position. The structure of the above-mentioned linkage radial position adjustment mechanism is: the ultrasonic probe 2 and the nozzle 11 are fixedly installed on the inner end of the rack 8, and the rack 8 slides and cooperates with the fixed guide rail 7 with a chute to keep the ultrasonic probe 2 The axis intersects the axis of the pipeline 1 and is perpendicular to ea...

Abstract

This invention relates to one multi-mouth tube online real-time hypersonic thickness measurement device, which comprises the following parts: hypersonic probe by pairs in radio shape around tube outside; water spray structure with focus hypersonic probe formed, wherein, the hypersonic probe and spray structure mouth are connected to the radium adjusting structure together with adjusting radium position to realize the multi-tube measurement.

Description

technical field [0001] The invention relates to an online real-time ultrasonic thickness measuring device for pipelines, in particular to an online real-time ultrasonic thickness measuring device for multi-diameter pipelines. Background technique [0002] After the pipe is processed and formed, if the outer diameter and wall thickness of the pipe are out of tolerance, it will not only bring difficulties to the installation, but also cause serious material waste. Excessive wall thickness eccentricity will affect the compressive strength and safety of the pipe. Therefore, online measurement and control of outer diameter and wall thickness eccentricity are very important. At present, due to the lack of precise measurement and control means and equipment in my country's pipe forming equipment, the extruded products produced have low dimensional accuracy, high scrap rate, and poor wall thickness uniformity, resulting in a great waste of raw materials. One of the current solutio...
