Description

Technical Field

[0001] The utility model relates to the technical field of pipeline detection, and more particularly to a rotary telescopic device for facilitating detection of external threads of petroleum pipelines. Background Art

[0002] An oil pipeline is a pipeline system used to transport oil and petroleum products. The main function of an oil pipeline is to transport oil and petroleum products safely and efficiently between oil fields and refineries, storage facilities or terminal markets. It is used to transport petroleum products processed by refineries (such as gasoline, diesel, aviation fuel, etc.) to the market. Oil pipelines are usually made of steel pipes, and the inner wall is coated with anti-corrosion materials to prevent corrosion. The pipeline may be buried underground, or it may be laid overhead or underwater. Its diameter can range from a few inches to several feet, depending on the expected flow rate and transportation distance. With the development of science and technology and the improvement of industrial quality, higher precision requirements are placed on oil pipelines. Therefore, detection equipment is needed to detect the external threads of oil pipelines.

[0003] In the process of inspecting oil pipelines, a rotary telescopic device is needed. However, the clamping mechanism of traditional rotary telescopic devices is mostly an integrated mechanism, and the clamping block cannot be disassembled. As a result, when the clamping block is damaged, it is more troublesome to repair it, which increases the cost of use.

[0004] And it does not have a cleaning function, which means that when there are impurities or dirt inside the external thread, the detection accuracy will be affected during the detection, affecting the final detection effect. Utility Model Content
