[0002] At present, in the oil and gas pipeline industry, the demand for single-tube diameter measurement and inspection for different domestic and foreign projects is becoming increasingly prominent. The previous diameter measuring tool is only composed of aluminum diameter measuring plates and connecting rods. Due to the structure and its own gravity in actual use, the tool cannot be located in the relative center of the pipeline, and then accurately detect the defects such as concave and plastic deformation of the circumferential surface inside the pipeline, which brings great hidden dangers to the production acceptance, transportation cargo damage inspection, actual engineering installation and use of the pipeline. Based on the above industry background, a new single-tube pipeline diameter measuring tool is designed to improve the many effects caused by pipeline defects. Utility Model Content

[0006] The utility model provides a further improvement of a new type of single-tube pipeline diameter measuring tool in that an extension shaft is provided at both ends of the fixed shaft, the extension shaft and the fixed shaft are integrally formed, the outer diameter of the extension shaft is smaller than the outer diameter of the fixed shaft, a thread is provided on the extension shaft, the extension shaft passes through the center of the diameter measuring plate, the diameter measuring plate is against the fixed shaft, a locking nut is threaded on the extension shaft, and the locking nut limits the diameter measuring plate.

[0007] A further improvement of the novel single-tube pipeline diameter measuring tool of the utility model is that a gasket is further arranged between the locking nut and the diameter measuring plate, and the extension shaft is further connected with a lifting ear.

[0008] A further improvement of the novel single-tube pipeline diameter measuring tool of the utility model is that the diameter measuring plate comprises an aluminum plate, and acrylic plates are arranged on both sides of the aluminum plate, and the diameter of the acrylic plate is smaller than the diameter of the aluminum plate.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] The utility model supports the fixed rotating shaft by arranging an adjusting member, thereby ensuring the stability of the position of the diameter measuring plate and thus ensuring the measurement effect; at the same time, the adjusting member can be adjusted and can be applied to pipes with different diameters, thereby ensuring the posture of the fixed shaft and the diameter measuring plate inside the pipe, and ensuring that the gap between the diameter measuring plate and the inside of the pipe always maintains a relatively balanced and uniform state, thereby ensuring the measurement accuracy.
