Multi-purpose digital ray automatic detection method

Abstract

The invention relates to a linkage type X-ray digital flat panel detection device for a straight weld steel pipe. The device comprises a creeper fixing frame, a walking imager creeper, a movable lifting ray machine device, a split type conveying roller way, a lifting rotating way and a system console, after information is fed back and summarized through the system console, a driving control command is sent, the split type conveying roller way and the lifting rotating way are sequentially driven to convey the to-be-detected straight welding seam steel pipe into the detection chamber and then jack up, adjust and position the to-be-detected straight welding seam steel pipe, and then the walking imager creeper and the movable lifting ray machine device are synchronously driven. And the X-ray machine and the imager are carried to carry out real-time linkage detection on the straight welding seam at the bottom of the steel pipe. The invention overcomes the defects of the traditional detection method and the prior art, saves the length space of the detection chamber, greatly improves the safety and reliability, greatly saves the equipment cost due to the simple and reliable structure, and has the advantages of convenience and simplicity in installation and maintenance, high detection sensitivity, stable detection efficiency and the like.

Description

technical field [0001] The invention relates to a multipurpose digital ray automatic detection method, in particular to a linkage type X-ray digital flat panel detection device and detection method. The following detection methods take straight welded seam steel pipe as an example. Background technique [0002] In recent years, the demand for straight welded steel pipes has been increasing, and the detection technology for straight welded steel pipes has also developed rapidly. At present, the traditional straight welded steel pipe inspection method is still to install the X-ray machine with a protruding arm more than ten meters long, and install the imager on the ceiling or side. The method of testing by moving as a whole requires a special testing room whose overall length is at least twice the length of the steel pipe line to complete the testing, which wastes the space layout of the site and increases the cost of radiation protection and the cost of mechanical equipment...

AI Technical Summary

Problems solved by technology

According to its detailed instructions alone, the inventive device still has the following defects: 1. Due to the large and complex structure of the probe arm of the inventive device, the extension structure is wide, the corresponding range of detection steel pipes is limited, and it is impossible to detect small-diameter steel pipes

2. When the steel pipe is on the pipe, the steel pipe needs to pass through the extended detection arm while being conveyed along the conveying roller table. When the steel pipe with a small diameter is conveyed, the steel pipe will flick and jump, and the detection equipment of the detection arm will occur. There is a risk of collision with the inner wall of the steel pipe. In addition, when the steel pipe is lifted by the lifting and rotating wheel assembly, the steel pipe will move upwards, and there is also the danger of collision with the fixed probe arm that is still in the middle of the steel pipe, and it will affect the detection of the steel pipe. Small range, poor safety performance

3. The X-ray tube support assembly is installed on the side wall and extends a long distance to the suspension mobile structure above the detection room. This structure is complex and heavy. It hangs at a certain height and has a long distance. Difficult to install and debug, difficult to maintain X-ray tubes and other equipment, equipment cost is also very high, frequent work, huge potential safety hazards
