Thickness measuring robot for pipeline inner wall

Abstract

The invention discloses a thickness measuring robot for a pipeline inner wall. The thickness measuring robot comprises a lifting bracket, a detection car body, a clean detection executing mechanism and an electronic control system, wherein the lifting bracket comprises a supporting rod, an electric capstan and an electric drive pusher; the detection car body comprises a driving wheel, a lighting lamp, a camera, a distance measurement probe, a thickness measuring host, a coupling agent container and an electric liquid pump; the clean detection executing mechanism comprises a mechanical arm, a servo motor and a tool tray; the electronic control system comprises a wireless communication module and an electric control module; and an electric polisher, a coupling agent nozzle module and a thickness measuring probe module are arranged on the tool tray. With adoption of the thickness measuring robot capable of automatically cleaning, polishing and detecting the pipeline inner wall, manual work at high altitude is avoided, safety of workers is guaranteed, and the thickness measuring robot is scientific and simple in structure, a complicated climbing mechanical structure of the robot is eliminated, and operation cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of pipe inner wall thickness measurement, in particular to a pipe inner wall thickness measurement robot. Background technique [0002] Pipeline inner wall thickness measurement is an essential part of pipeline safety. By detecting the thickness of the pipe material, the thinning of the pipe due to corrosion during use can be grasped. In pipe thickness measurement, ultrasonic thickness gauges are commonly used equipment; usually large-scale pipelines can be manually inspected by staff carrying ultrasonic thickness gauges into the pipe; when measuring thickness, usually the staff must first clean the surface of the material to be tested, Remove the attachment, apply coupling agent, and then use the ultrasonic probe to measure the corresponding test point. For pipelines that cannot be entered manually, pipeline endoscopic robots are usually used to carry detection equipment into the pipeline for inspection. ...

Problems solved by technology

[0003]In the real environment, there will be greater obstacles and difficulties in using manual detection

For example, manual detection of high-altitude chimneys will have safety issues; for example, small pipelines buried deep underground can neither be detected from the outside nor manually entered into the pipeline. In these cases, it is necessary to use detection robots to inspect the pipeline. The thickness of the inner wall is tested
