Problems solved by technology

However, due to the high requirements for the flexibility of the structure of the pipeline robot, it is difficult for the general rigid body mechanical structure to realize the inspection of pipelines with narrow, multi-way bifurcations and variable pipe diameters, and the structure with poor rigidity often reduces the measuring device. Detection accuracy

Abstract

The invention discloses a flexible pipeline routing inspection device. The flexible pipeline routing inspection device comprises a front driving device, a back driving device, a visual measurement system and a flexible connecting rod. The height of a hanging frame is changed through an eccentric wheel, so that a movement mechanism can elongate and shorten, and wheels of the routing inspection device can be attached to the pipe walls of pipelines with different diameters to move; landing load and terrain parameters of a loading point are measured in real time through a force sensor arranged oneach movement mechanism; geometric morphology measurement, route navigation and temperature monitoring of the pipeline can be realized through the visual measurement system; and the front driving device and the back driving device twists relatively through a flexible connecting rod, so that turning and steering in a multipass bifurcated pipe is realized. Based on the flexible pipeline routing inspection device, the site routing inspection requirement of the complex pipeline working condition is met.

Description

technical field [0001] The invention belongs to the technical field of automation, and relates to a flexible pipeline inspection device, which is suitable for inspection of complex-diameter and multi-way bifurcated pipelines. Background technique [0002] At present, pipeline inspection is an important part of major engineering fields such as underground pipeline engineering, long-distance high-voltage power transmission and distribution, tunnel and bridge engineering, urban planning, and smart buildings. It is also an important part of infrastructure construction such as national defense and people's livelihood. However, due to the wide variety of pipelines in various engineering application fields, complex lumen environment, and various inspection indicators, the manual inspection method has seriously restricted the inspection quality and efficiency of large-scale pipeline engineering projects. Therefore, using the inspection device installed with detection sensors to comp...
