Embodiment Construction

[0029] Embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0030] The large-diameter seamless steel pipe ultrasonic / eddy current combined automatic detection equipment of the present invention is composed of a rotating raceway 1, a three-wire track 2, a detection gantry 3, a probe tracking vehicle 4 and a follow-up operation vehicle 5, etc., such as figure 1 shown.

[0031] The rotating raceway 1 is composed of two or three sets of rollers, and the rollers are dragged and rotated by the motor 6, such as figure 2 shown. When the steel pipe is placed on the raceway, the steel pipe is driven by the roller to rotate in situ. The rotation speed of the steel pipe can be adjusted through the frequency converter according to the steel pipe diameter and flaw detection requirements. The steel pipe is hoisted to the raceway by the crane in the workshop. In order to avoid the impact on the raceway when the steel pipe is hoiste...

Abstract

The present invention relates to an ultrasonic and backset combined automatic examining device and the application thereof for large-caliber seamless steel tube. The present invention comprises a rotating raceway, a three-way track, a detecting gantry, a probe tracing vehicle, and a following operation vehicle. The rotating raceway drags the steel tube to rotate in place, the detecting gantry drives the probe system to move axially along the steel tube being tested, and then the ultrasonic and a backset probe draw a spiral scan trace along the surface of the steel tube. Adjusting the rotationspeed of the raceway and the progress speed of the gantry can realize a leak-free and overall examination of the whole steel tube body. The present invention solves the difficult problem that the seamless steel tube with the diameter being more than 180mm adopts a manual injury detecting method and cannot realize the automatic detection. The present invention can ensure the two kinds of injury detection to operate simultaneously and to be completed at one time, can detect the surface defect as well the inner defect of the steel tube with high automatization degree and high detecting efficiency.

Description

technical field [0001] The invention belongs to the technical field of automatic flaw detection of steel pipes, in particular to an ultrasonic and eddy current combined automatic detection device and application of large-diameter seamless steel pipes. Background technique [0002] Large-diameter seamless steel pipe refers to seamless steel pipe with a diameter greater than Φ180mm. It is an important material in industries such as boilers, pressure vessels, electric power, machinery, petroleum, and chemical industry. Among them, large-diameter high-pressure boiler pipes that are resistant to corrosion and high pressure, and natural gas transmission Pipelines, oil pipelines, etc. are becoming hot spots of demand as the country increases investment in energy infrastructure. These special-purpose seamless steel pipes have high quality requirements, and once there are defects, catastrophic accidents often occur. [0003] The existing seamless steel pipe manufacturing technology ...
