[0028] The present invention will be described in detail below with reference to the drawings and specific embodiments.
[0029] The invention provides a pneumatic circulating pipe diameter detection device, such as figure 1 As shown, the base 1 is included. The base 1 is set on the ground of the drilling site and is a closed structure; the two ends of the base 1 are respectively provided with a detection unit, each detection unit includes a diameter detection mechanism assembly 14, each diameter detection mechanism The assembly 14 is connected with a diameter gauge 15. At least two pipe string positioning frames 2 are arranged on the base 1 between the two detection units. The pipe string positioning frames 2 are in a V-shaped groove structure, and the upper part of the V-shaped groove is arranged There is a kick-out mechanism, which can realize the automatic kick-out of the pipe string. The pipe string is placed on the pipe string positioning frame 2, and the base 1 is also prov...
