Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: a kind of pipeline girth weld non-destructive testing device, packet
Support plate 1 is included, stabilizer blade 2 is symmetrically welded at left and right sides of 1 bottom of support plate, installation is welded between stabilizer blade 2 described in two sides
Plate 3 is equipped with gas compressor 4 at the top of the mounting plate 3, and the 4 left side gas outlet of gas compressor is connected with by hose
Pneumatic head 5, the 1 top left and right sides of support plate are symmetrically bolted with mounting rack 10, and 10 top of mounting rack described in two sides is welded
There is bearing 8,8 inner cavity of bearing described in two sides is plugged with end cap 6, is provided with valve inside 7, the branch at the top of the end cap 6 of left side
1 top right side of fagging is equipped with motor 12, and the 12 left side power output end of motor is connected with shaft 11 by shaft coupling, described
The left end of shaft 11 and the right side wall of right side end cap 6 are spirally connected, and 1 top center position of support plate is bolted with detection ring 9, described
Ultrasonic detecting probe 13 is installed at the top of detection 9 internal chamber wall of ring.
Wherein, 1 top center position of support plate uniformly laterally offers screw hole, facilitates and adjusts between two sides end cap 6
