Problems solved by technology

[0003] The existing connecting mechanisms based on flaw detection and positioning of welded joints of oil pipelines are all single-rotation, which makes it impossible to enter some large-angle bent pipelines, and the scope of use is poor. They are all in a fixed state, resulting in accurate flaw detection only for pipes with one diameter. When the diameter is too large, the device will shake when moving and reduce the stability.

Abstract

The invention provides a connection mechanism based on the flaw detection and positioning of welded joints of petroleum pipelines, comprising a front hexagonal connection end, a first connection, a second connection, a rear hexagonal connection, a ball head, a hollow threaded column, an oil storage tank, a hollow thread A rod, a pulley block, a sliding rod and a piston, the rear end of the front hexagonal connection end is provided with a connector 1, the rear end of the connector 1 is provided with a ball head, and the rear end of the ball head is provided with a connector 2, so The second rear end of the connecting piece is provided with a rear hexagonal connecting end. This design adopts a double rotating mechanism, which is more suitable for pipes with different bending angles. The outer end of the hollow threaded column is provided with an oil storage tank. A hollow rod is installed at the end, a pulley block is installed at the outer end of the hollow rod, and a piston is installed at the inner end of the hollow rod. This design can adjust the extension length of the pulley block. Sex is high.

Description

technical field [0001] The invention relates to a connection mechanism based on flaw detection and positioning of oil pipeline welded joints, and belongs to the technical field of pipeline flaw detection and positioning. Background technique [0002] Petroleum, one of the main objects of geological exploration, is a viscous, dark brown liquid known as the "blood of industry." There are oil reserves in parts of the upper crust. The main component is a mixture of various alkanes, naphthenes and aromatic hydrocarbons. Petroleum is mainly used as fuel oil and gasoline, and is also a raw material for many chemical industry products, such as solutions, fertilizers, pesticides and plastics. Petroleum is usually transported by pipelines, so pipe welding requires higher quality. [0003] The existing connecting mechanisms based on flaw detection and positioning of welded joints of oil pipelines are all single-rotation, which makes it impossible to enter some large-angle bent pipeli...
