Background technology
Transfer oil, rock gas labour spiral welded steel pipe, through the operation for many years, for various reasons spiral weld may occur the damage or defective, so when the pipeline overhaul, must carry out nondestructive flaw detection examination to spiral weld.Up to the present, also do not have to carry out the scanner that on-the-spot spiral weld detects at spiral welded steel pipe specially.Be import equipment with ultrasonic wave diffraction time difference method spiral welded steel pipe checkout equipment now, domestic do not have a like product.Be single group probe scanning frame of coordinative composition of equipments, there are the following problems:
1) a kind of scanning frame of specification can only corresponding be applicable to a kind of ultrasonic wave diffraction time difference probe of specification;
2) the probe spacing adjustable range is little, and maximum spacing can only reach 250mm;
3) there is not scale on the slide link of scanning frame, inconvenient between the probe during operation apart from control;
4) price height, a secondary import Φ 3mm scanning frame, about 2.3 ten thousand yuan of cost Renminbi.
The utility model content
The purpose of this utility model is: provide a kind of ultrasonic wave diffraction time difference method to detect single group probe scanning frame, the probe that is used for clamping and fixing a pair of ultrasonic wave diffraction time difference method checkout equipment, two probes can stably be remained on the same straight line not to be rocked, can adjust probe spacing according to action need, and can be applicable to the probe of plurality of specifications.The single group probe scanning frame that fixes probe is applied to detect the butt welded joint of special equipment.
The technical solution adopted in the utility model is: the ultrasonic wave diffraction time difference method detects single group probe scanning frame, mainly is made of a slide link and two cover clamping assemblies, and it is characterized in that: two cover clamping assemblies are connected on the slide link.Every cover clamping assembly mainly comprises: grip block, holding piece, bolt, short tube and screw are formed, and grip block is a T shape structure, and a through hole is arranged on the top of grip block, and slide link is arranged in the through hole.Slide link is cylindrical, can slide in the through hole of grip block.Screw is arranged at the top at grip block, has screw that grip block is fixed on the slide link in the screw.Lower side at grip block has two holes vertical with the slide link center line.Lower side at grip block is fixed with holding piece respectively.Holding piece is a rectangle, and holding piece one end has two connecting holes, and two bolts pass two holes of two connecting holes and the grip block of holding piece, holding piece is fixed on the both sides of grip block.The middle fixedly ultrasonic probe of two holding pieces.
For the fixing ultrasonic probe of plurality of specifications, change the distance between two holding pieces, between holding piece and grip block, short tube is arranged, short tube is used to regulate the clamping width to adapt to the probe of different size.
The scale of fluted shape on the slide link, be used to regulate between the two cover clamping assemblies apart from the time, can judge probe spacing easily and accurately.
Grip block is selected aluminum alloy material for use.Short tube is selected the brass material for use.
For satisfying on-the-spot actual detected requirement, the length of slide link is between 500～850mm.The maximum spacing of adjusting can reach 550mm.
The beneficial effects of the utility model: the ultrasonic wave diffraction time difference method detects single group probe scanning frame, 1) applied widely, but the ultrasonic probe of clamping Φ 12.7mm, Φ 25.4mm, three kinds of specifications of Φ 3mm; 2) the probe spacing adjustable range is big, and maximum spacing can reach 550mm; 3) the ultrasonic probe spacing can be adjusted, and on the slide link of scanning frame scale is arranged, and can make things convenient for, accurately judge the center distance of probe.4) cost is low, and the material and the processing cost of the single group of the cover probe scanning frame of the utility model design are 400 yuan.
