Problems solved by technology

[0002] Due to the large diameter and length of large steel pipes, it is very inconvenient during production and transportation, and it is even more difficult to conduct non-destructive testing on steel pipes
At present, there are many types of equipment for flaw detection, but the common shortcomings are low degree of automation, low efficiency, and small application range, which increases the workload of surveyors.
[0003] At present, there are also steel pipe flaw detection vehicles that perform non-destructive flaw detection on steel pipes due to the fact that steel pipes are not easy to move. However, this flaw detection method is not efficient and cannot classify the steel pipes after inspection.

Embodiment Construction

[0037] A preferred embodiment of the present invention will now be described in detail below with reference to the accompanying drawings.

[0038] As shown in Figure 1, the eddy current flaw detection equipment of the present invention is composed of a feeding rack 1, a feeding rail 2, a front pressing wheel mechanism 3, a detection host 4, a feeding rail 6, a feeding frame 7 and a control computer. When conducting non-destructive testing of steel pipes, first place the steel pipes to be tested on the feeding rack 1 neatly. After the non-destructive testing starts, the control computer sends a start command to the cylinder 31 of the feeding rack, and the feeding lever 8 moves the steel pipe to the shelf 15 of the feeding rail 2 . The cylinders 20 at both ends of the feeding rail 2 place the steel pipes on the shelf 15 on the conveying wheels through the linkage mechanism. When the steel pipe is sent to the front pressure roller mechanism 3 on the conveying wheel, the photoele...

Abstract

The present invention provides an eddy-current inspector including ultrasonic flaw detector, eddy current detector and computer, whose structure comprises of feeding rack, feeding orbit, pressing wheel mechanism, testing mainframe, blanking orbit and blanking rack, feeding orbit, pressing wheel mechanism, testing mainframe, pressing wheel mechanism and blanking orbit are connected in turn, feeding rack and blanking rack are set on one side of feeding orbit and blanking orbit respectively. The eddy-current inspector of present invention has merits of reasonable design and simply operation, and saves a great deal manpower and material resources, so it has a well widely use value.

Description

1. Technical field [0001] The invention relates to a non-destructive testing technology for steel pipes, in particular to a computer-controlled eddy current testing device. 2. Background technology [0002] Due to the large diameter and length of large steel pipes, it is very inconvenient during production and transportation, and it is even more difficult to carry out non-destructive testing of steel pipes. At present, there are many types of equipment used for flaw detection. The common shortcomings are that the measurement automation is low, the efficiency is not high, and the application range is small, thus increasing the workload of the measurement personnel. [0003] At present, there are also steel pipe flaw detection vehicles for non-destructive testing of steel pipes for the characteristics of steel pipes that are not easy to move. 3. Contents of the invention [0004] The purpose of the present invention is to provide an eddy current flaw detection device that c...
