Embodiment Construction
[0032] The present invention will be further described in detail below in combination with a steel pipe flaw detection system adopting the structure of the present invention and the accompanying drawings.
[0033]During specific implementation: if Figure 1 to Figure 10 shown.
[0034] A steel pipe flaw detection system, including a base plate, on which a steel pipe transmission device 1 for driving the steel pipe to move along the axis direction and a steel pipe flaw detection device 2 arranged on the steel pipe movement path are arranged on the bottom plate, and a steel pipe feeding straightening device arranged on the bottom plate Device 3, steel pipe feeding and straightening device 3 is arranged at the feeding end of the steel pipe transmission device and is used for straightening the steel pipe.
[0035] In this way, the steel pipe is straightened first and then the material is fed for flaw detection, which can better avoid the influence of the straightness or surface q...

The invention discloses a power device for flaw detection of steel pipes, comprising a steel pipe transmission device, characterized in that the steel pipe transmission device includes a steel pipe advancing mechanism for driving the steel pipe along the axis, and also includes a The steel pipe rotating mechanism rotates in the center; the steel pipe advancing mechanism includes a pair of advancing rollers, and the circumferential surface of the advancing rollers is provided with concave arc-shaped friction grooves, and the friction grooves on the circumferential surface of the advancing rollers are oppositely arranged and used to clamp the steel pipe on the In it, the two advancing rollers are respectively connected to the same motor for advancing the steel pipe through a set of advancing roller transmission mechanism, and the motor for advancing the steel pipe is used to drive the two advancing rollers to rotate relative to each other to drive the steel pipe forward. The invention has the advantages of simple structure, compact layout, stability and reliability, and can realize the spiral forward transmission of the steel pipe to increase the detection range of the steel pipe probe and improve the reliability of the detection.
Description
technical field [0001] The invention relates to a steel pipe flaw detection device; in particular, it relates to a power device for steel pipe flaw detection. Background technique [0002] Steel pipe is an important steel material widely used. Due to various factors in the production process of steel pipe, defects such as longitudinal cracks, transverse cracks, folding, and delamination often exist on the steel pipe wall. If the steel pipe is defective, it will break during use and cause accidents, and even cause serious consequences, which may cause major economic losses or even casualties. For this reason, steel pipes for important purposes require complete non-destructive testing equipment to conduct online flaw detection on steel pipes. To ensure the quality of steel pipes leaving the factory, the existing flaw detection methods mainly include ultrasonic flaw detection and eddy current flaw detection inspection methods. The existing steel pipe flaw detection line often ...
