The main body frame is formed by connecting two end frames together through a connecting rod, and a scanning device mounting cross beam is arranged between the two end frames of the main body frame; the upright columns at the four corners of the main body frame are respectively provided with a telescopic supporting leg, and the supporting legs are provided with rollers; the telescopic supporting legs are connected with the main body frame upright column through T-shaped connecting grooves and fixed with locking nut blocks positioned in the T-shaped grooves through handle bolts. The scanning device mounting beam on the main body frame is a beam with a dovetail groove, comprises a scanning probe elastic loading arm, an encoder and a scanning device of a probe scanning wedge block, and is connected with the scanning device mounting beam through the dovetail groove. Has the characteristics of simple structure, convenient use and stable and reliable performance. The method is suitable for nondestructive flaw detection of linear welding seams, annular welding seams and spiral welding seams of various large-sized welded pipes.
Description
Technical Field
The utility model belongs to supersound nondestructive test detection apparatus field mainly relates to the manual spiral pipe welding seam that can carry out nondestructive test to the welding seam of great spiral welded tube and surveys ware support is swept.
Background
The nondestructive inspection of the welding seam of large-scale welded pipe is generally carried out by placing a scanning device on a scanning frame with wheels, placing the scanning frame on the pipe to be inspected, and enabling the scanning device to walk along the welding seam, thus carrying out nondestructive inspection on the welding seam. Because the wheels of the scanning frame are on the same plane, the scanning of the linear welding seam and the annular welding seam is easy to realize, and the scanning of the spiral welding seam of the spiral welded pipe has problems. Because the scanning device needs to run along the direction of a spiral-line-shaped welding line, four wheels on the same plane on the scanning frame cannot simultaneously contact the surface of the spiral welding pipe, and the accuracy of a scanning result is affected. Therefore, the four wheels of the scanning support are required to be adjusted according to different pipe diameters, so that the four wheels are all in contact with the surface of the pipe, and the purpose of conveniently and accurately carrying out nondestructive flaw detection on the spiral welding line is achieved.
Disclosure of Invention
The utility model aims at providing a manual spiral pipe welding seam is swept and is looked into ware support is swept with this ware support of looking into of sweeping can not only carry out nondestructive test to the sharp welding seam and the circumferential weld of pipe, can also carry out nondestructive test to the spiral welding seam of pipe.
The utility model discloses a realize through following measure, include main part frame, landing leg and sweep and look into device installation crossbeam, characterized by: the main body frame is formed by connecting two end frames together through a connecting rod, and a scanning device mounting cross beam is arranged between the two end frames of the main body frame; the upright columns at the four corners of the main body frame are respectively provided with a telescopic supporting leg, and the supporting legs are provided with rollers; the telescopic supporting legs are connected with the main body frame upright column through T-shaped connecting grooves and fixed with locking nut sliders positioned in the T-shaped grooves through handle bolts.
The scanning device mounting beam on the main body frame is a beam with a dovetail groove, and comprises a probe elastic loading arm, a roller type encoder and a scanning device of a probe scanning wedge block, and the scanning device mounting beam is connected with the scanning device mounting beam through the dovetail groove.
When the scanning device support is used for scanning spiral welded pipes, the telescopic supporting legs connected to the main body frame are adjusted according to the diameter of the spiral pipe, and the walking wheels on the four telescopic supporting legs are in contact with the surfaces of the pipes under the condition that the mounting beams of the scanning device are perpendicular to the welding seams at the scanning position. And pushing the scanning device bracket by hand to keep the two probe scanning wedge blocks to be positioned on two sides of the spiral welding line all the time, thereby carrying out scanning operation.
The beneficial effects of the utility model are that, because the landing leg of scanning the ware support is the telescopic, when scanning the spiral welding seam, according to the length of the big or small adjustment landing leg of pipe diameter, make the surperficial equilibrium of four gyro wheels and pipe stable contact, can guarantee to detect a flaw and scan the accuracy of examining the result. The scanner support is not only suitable for the welding seam of a spiral pipe, but also suitable for the linear welding seam and the annular welding seam of the pipe, and the lengths of the four supporting legs are adjusted to be the same. Has the characteristics of simple structure, convenient use and stable and reliable performance. The method is suitable for nondestructive flaw detection of linear welding seams, annular welding seams and spiral welding seams of various large-sized welded pipes.
