Oil pipeline crack detection device

Abstract

The invention provides an oil pipeline crack detection device. The oil pipeline crack detection device comprises a carriage, a circumferential radiation X-ray flaw detection machine is mounted on thecarriage, a pair of front ground wheels and a pair of rear ground wheels are arranged on the bottom of the carriage, and a driver for driving the front ground wheels or the rear ground wheels is mounted on the carriage; a counterweight is arranged on the carriage; a group of carriage plates are hinged from the front ground wheels to the rear ground wheels to form the carriage; and the front groundwheels and the rear ground wheels are provided with anti-skid lines. The oil pipeline crack detection device is applicable to the detection of cracks of long-range oil pipelines, and is flexible andconvenient to move.

Description

Technical field: [0001] The invention relates to an oil pipeline crack detection device, which belongs to the technical field of mechanical equipment. Background technique: [0002] Before and after the oil pipeline is put into operation, a comprehensive pipeline flaw detection operation is required. The project is huge and requires a lot of human, material and financial resources. In order to ensure the stability of the pipeline, it is usually necessary to perform flaw detection on the pipeline, to detect whether there are cracks at the welded joints, to detect whether there are longitudinal cracks on the inner wall of the pipeline, etc., and usually the pipe wall has a certain thickness, so it is difficult to accurately detect cracks from the outside. Therefore, it is necessary to enter the interior of the pipeline for flaw detection. However, because the pipeline is very long, and the internal environment is harsh, some pipelines have residual toxic gas, etc., it is impo...

Problems solved by technology

[0003] However, there are various rubbish and sundries remaining at the bottom of many pipelines. It is inconvenient for wheeled, crawler and walking robots to move after entering. They are not flexible enough to move in the pipeline, and there are slopes that slope upward inside the pipeline. Many pipeline robots climb slopes. Poor ability, some pipeline robots can only move forward, but cannot move backward, usually cannot retreat when entering a closed pipeline, and are not flexible enough
