Problems solved by technology

However, the ray source positioned by the radioactive source is easy to lose in preservation, and the loss will cause animals or people to be exposed to radiation radiation, which will pose a major threat to the health of operators, surrounding animals and other people
Magnetic control positioning is easily affected by the residual magnetism and magnetization of the pipeline, and misoperations occur due to mis-issued instructions, which will cause the driving trolley and flaw detection device to break away from the pipeline and be damaged, and cause safety problems such as radiation

Abstract

A subaudio frequency positioning-based pipeline crawler comprises an X-ray generator, a driving dolly and a subaudio frequency positioning source; the subaudio frequency positioning source comprises a box body, a control circuit board, a power supply unit and a signal emitting unit are arranged in the box body, the control circuit board is integrated with a subaudio frequency digital modulating unit and a power amplifying unit, and the box body is provided with trigger buttons A, B, C and D; and the driving dolly is provided with a dolly body, the dolly body is respectively provided with a driving box, a battery box and a control box, a stepping motor is arranged in the driving box, the upper side of the control box is provided with a signal receiving unit through an adjustable telescoping rod, a control system is arranged in the control box, and the control system comprises a signal amplifying unit, a shaping filtering unit, a subaudio frequency decoding unit and a PLC. The subaudio frequency positioning-based pipeline crawler is simple to operate, is clean and environmentally-friendly, and realizes flaw detection of the X-ray generator in a pipeline to be detected and accurate control of advancing, retreat and stopping of the driving dolly through the subaudio frequency positioning source.

Description

technical field [0001] The invention relates to the technical field of electromechanical control, in particular to a pipeline crawler based on subaudible positioning. Background technique [0002] Pipeline crawlers are widely used in defect inspection and repair of various pipelines such as natural gas pipelines and oil pipelines. When the pipeline crawler is in use, it mainly places the flaw detection device (X-ray generator) and its connected driving car inside the pipeline to be tested, and the inspector controls the driving car through the positioning device and makes the flaw detection device and the driving car complete. corresponding action. [0003] At present, pipeline crawlers mainly adopt two positioning methods: radioactive source positioning and magnetic control positioning. However, the ray source positioned by the radioactive source is easily lost in preservation, and the loss will cause animals or people to be exposed to radiation, which will pose a major t...
