Gas pipeline detector entering and taking out vehicle

Abstract

The invention discloses a gas pipeline detector entering and taking out vehicle. The vehicle comprises a main detector entering and taking out vehicle body and an auxiliary detector entering and taking out vehicle body which are connected with each other and each provided with a wheel mechanism. Arc-shaped brackets are arranged on the main detector entering and taking out vehicle body and the auxiliary detector entering and taking out vehicle body; a propulsion oil cylinder is arranged on the main detector entering and taking out vehicle body, a hook device is arranged on the auxiliary detector entering and taking out vehicle body, and vertical supports are symmetrically arranged on the main detector entering and taking out vehicle body and the auxiliary detector entering and taking out vehicle body; and by arranging the two detector entering and taking out vehicle bodies which are connected with each other, the effect of bearing a spherical detection section and a power section of a pipeline magnetic flux leakage inner detector is achieved, so that the inner detector can stably achieve the detection effect on the inner wall of the pipeline in the transportation process of the detector entering and taking out vehicle bodies in the pipeline, and accidental loss caused by unstable pipeline detection is avoided. By arranging the wheel mechanisms with backstops and springs, stablemovement of the detector entering and taking out vehicle bodies is guaranteed, and meanwhile it is avoided that the inner detector falls off due to sudden reverse movement of a trailer, and thereforethe use safety of the detector entering and taking out vehicle bodies is not affected.

Description

technical field [0001] The invention relates to the technical field of internal detection in long-distance oil and gas pipelines, in particular to a carrying vehicle capable of carrying a receiving and receiving ball for a detector in an oil and gas pipeline. Background technique [0002] The operating pressure of the gas pipeline is high, and any tiny pipeline leakage or damage failure will be catastrophic. Internal magnetic flux leakage detection of long-distance oil and gas pipelines uses transmission media such as oil and gas to push the detectors to walk in the pipelines to detect and record the deformation, corrosion and other damages of the pipelines in real time. It is currently the most accurate and efficient pipeline safety maintenance method recognized internationally. However, when the detector initially enters the pipeline (serving the ball) and takes it out (receiving the ball), there is no transmission medium inside the pipeline as a driving force, which makes...
