Abstract
The utility model discloses an angle controller in ray detection, which comprises a semicircle angle measuring instrument, and is characterized in that a rotatable fixed pin is arranged at the round point of the semicircle angle measuring instrument; the rotatable fixed pin is taken as an end point, and a telescopic pointer is arranged along the direction of the cambered surface of the semicircle angle measuring instrument. Through adopting the technical proposal, the angle controller in ray detection effectively and greatly improves the detectable rate of the default in the welding seam, and greatly improves the qualification rate of the radiographic film and the detection sensitivity; the angle controller in ray detection reduces the labor intensity of the detecting personnel, and improves the labor efficiency; the angle controller in ray detection greatly reduces the consumption of films, saves the cost, and improves the economic efficiency; simultaneously, the enhancement of the sensitivity also reduces the probability of the superstandard default, the accident hidden danger is reduced, and the angle controller in ray detection is economic and practical, has convenient carrying and convenient operation, can effectively control the detection quality, and is suitable for the ray detection of the dual-wall and dual-projection radiographic imaging of the pipe butt-jointed seam.
Description
Technical field
The utility model relates to a kind of controller in ray detection, especially relates to a kind of angle controller during double-wall double-projection imaging method uses in ray detection.
Background technology
At present, at present, in ray detection, control method to tubule butt-weld double-wall double-projection elliptic imaging mainly adopts the method for offset distance to finish the elliptic imaging of egative film, but the method is subjected to the restriction of many conditions: 1, Guan Jingtai is little, when wall thickness is too big, can't carry out.When 2, the locus is narrow and small, can't use.When 3, the position at pipe trend and weld seam place is undesirable, can't use.
The method of offset distance can't realize or the situation that is difficult to realize under ray detection have only the angle of employing transillumination to realize, in present the method is to realize by people's naked eyes, this method of judging with naked eyes has caused a large amount of underproof radiographic films, to these defective egative films must be once more transillumination again, the great amount of manpower financial resources have been wasted, missed optimum detection opportunity, incured loss through delay the duration of a project, made economic benefit be subjected to loss; Simultaneously also make detection sensitivity can not reach requirement, lowered the defective recall rate, make engineering imply potential safety hazard.
Summary of the invention
The purpose of this utility model is to overcome the defective of the deficiencies in the prior art and existence, finishes angle orientation more accurately, increases substantially the quality of ray detection, realizes the instrument that accurately takes measurement of an angle.
The purpose of this utility model can realize by following measure:
The utility model comprises semicircle angle measuring tool, it is characterized in that: the round dot place at described semicircle angle measuring tool is provided with rotatable fixed pin; With rotatable fixed pin is end points, is provided with scalable pointer along the cambered surface direction of semicircle angle measuring tool.
On described scalable pointer, be provided with the fixed angle pin.
Semicircle angle measuring tool is the angle measuring tool of aluminum.
The radius of semicircle angle measuring tool is 100mm～200mm.
The radius of semicircle angle measuring tool is 150mm.
Described scalable pointer maximum length surpasses the radius of semicircle angle measuring tool, is 200mm～600mm.
Base at semicircle angle measuring tool is fixed with magnet piece with screw.
Described magnet piece is an arc.
On the base of described semicircle angle measuring tool, be the center with the round dot, be provided with fixed band on its both sides.
Angle controller in the ray detection of employing technique scheme increases substantially defective recall rate in the weld seam effectively, increases substantially the qualification rate and the detection sensitivity of radiographic film; Reduce testing staff's labour intensity, raise labour efficiency; Reduce the egative film consumption greatly, save cost, increase economic efficiency; The raising of sensitivity has simultaneously also reduced the probability that exists of overproof defective, has lowered the hidden danger of accident, and economical and practical, easy to carry, simple operation, effectively the control detection quality is applicable to that comprehensive tube butt welding stitches the ray detection of double-wall double-projection imaging.
Description of drawings
Fig. 1 is an one-piece construction synoptic diagram of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises semicircle angle measuring tool 1, is provided with rotatable fixed pin 4 at the round dot place of semicircle angle measuring tool 1; With rotatable fixed pin 4 is end points, is provided with scalable pointer 2 along the cambered surface direction of semicircle angle measuring tool 1.On described scalable pointer 2, be provided with fixed angle pin 3.Described semicircle angle measuring tool 1 is the angle measuring tool of aluminum, and its radius is 100mm～200mm, and the radius during best user mode is 150mm.Described scalable pointer 2 maximum lengths surpass the radius of semicircle angle measuring tool 1, are 200mm～600mm.And the base at semicircle angle measuring tool 1 is fixed with magnet piece 5 with screw 6, and magnet piece 5 is an arc.On the base of described semicircle angle measuring tool 1, be the center with the round dot, be provided with fixed band 7 on its both sides.
Specifically, when ray detection, with angle controller be adsorbed on detect on the weld seam, angle value as required stretches scalable pointer 2 and determines its angle value, this moment, the direction of scalable pointer 2 indications was the direction that ray is injected.Fixed angle pin 3 is fixed on scalable pointer 2 on the angle measuring tool 1, is convenient for measuring.Thus, according to the situation of locus, scalable pointer 2 can accurately be made the position of ray generator.
Arc-shaped magnet 5 can be adsorbed on angle controller on the detected object.Simultaneously, because the difference of detected object, what arc-shaped magnet can not be firm is adsorbed on angle controller on the detected object, at this moment, fixed band system can be tied up on detected object convenient the detection.
