Description
Technical field
The utility model relate to reelability the radiographic inspection radioprotector, more specifically refer to ray inspection machine stem pipe place radioactive source radiation shield device, be applicable to the radiographic inspection operation.
Background technology
Pressure pipeline in the large-scale petrochemical device, pressure vessel etc., in installation, maintenance, transformation process, often use gamma-ray machine that welding joint is carried out radiographic inspection, whether have defectives such as crackle, incomplete fusion, lack of penetration, slag inclusion, pore to determine worker's welding joint inside.
Existing gamma ray inspection device work synoptic diagram, when detecting a flaw operation, operating personnel drive the core cable radioactive source are moved to exposure position from the shielding restoration position by the stem pipe, detect a flaw.When radioactive source leaves flaw detection organism after stem is managed exposure position, in this process, lose screen layer, radioactive source is in 360 degree radiation regimes, big to operating personnel and ambient radiation dosage, need isolate operation field during operation, all there are restriction in working space and time, not only dangerous but also not environmental protection.
The utility model content
To be the radioactive source that solves ray inspection machine move to the detect a flaw radiation problem of process of exposure position from the shielding restoration position by the stem pipe to the purpose of this utility model.
For achieving the above object, the utility model provide a kind of reelability ray inspection machine stem tube shield device, it is characterized in that: by flexibility stem pipe, the spherical shield foundry goods, cylindricality shielding foundry goods, the cylindricality shielding foundry goods that connects probe, the plug shape shielding foundry goods that connects defectoscope constitutes, spherical shield foundry goods and cylindricality shielding foundry goods are spaced, the spherical shield foundry goods is located at two ends and shields foundry goods with the cylindricality that is connected probe respectively, the plug shape shielding foundry goods that connects defectoscope links to each other, spherical shield foundry goods center has the through hole that adapts with flexible stem external diameter of pipe, cylindricality shielding foundry goods two ends are equipped with the groove that is coupled with spherical shield cast(ing) surface radian, the bottom portion of groove center has the through hole that adapts with flexible stem external diameter of pipe, the cylindricality shielding foundry goods that connects probe is equipped with the groove that is coupled with spherical shield cast(ing) surface radian with plug shape shielding foundry goods one end that is connected defectoscope, and the bottom portion of groove center all has the through hole that adapts with flexible stem external diameter of pipe.
The utility model is connected in series spaced spherical shield foundry goods and cylindricality shielding foundry goods by flexible stem pipe, and the cylindricality shielding foundry goods by connecting probe and the plug shape shielding foundry goods that is connected defectoscope connect directed beam respectively and expose and pop one's head in and ray inspection machine, can make the shielding foundry goods cover flexible stem tube outside fully and form shield assembly, controlled the exposure of radioactive source effectively to surrounding environment, reduce protection distance, guaranteed the operator and the public's x radiation x safety.Because ray operation control zone radius is little, can realize and other work post cross-operation, has improved operating efficiency.
Description of drawings
Fig. 1 is a ray inspection machine stem tube shield apparatus structure synoptic diagram;
Fig. 2 is a spherical shield foundry goods stereographic map;
Fig. 3 is a cylindricality shielding foundry goods stereographic map;
Fig. 4 is the cylindricality shielding foundry goods stereographic map that connects probe;

Embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, the cylindricality shielding foundry goods 4 that the utility model is popped one's head in by flexibility stem pipe 1, spherical shield foundry goods 2, cylindricality shielding foundry goods 3, connection, the plug shape shielding foundry goods 5 that connects defectoscope constitute, spherical shield foundry goods and cylindricality shielding foundry goods are spaced, and the spherical shield foundry goods is located at two ends and links to each other with the plug shape shielding foundry goods of the cylindricality shielding foundry goods that is connected probe, connection defectoscope respectively.
With reference to Fig. 2, spherical shield foundry goods center has the through hole 6 that adapts with flexible stem external diameter of pipe.
With reference to Fig. 3, cylindricality shielding foundry goods two ends are equipped with the groove 7 that is coupled with spherical shield cast(ing) surface radian, and the bottom portion of groove center has the through hole 8 that adapts with flexible stem external diameter of pipe.
With reference to Fig. 4, cylindricality shielding foundry goods one end that connects probe is provided with the groove 9 that is coupled with spherical shield cast(ing) surface radian, and the bottom portion of groove center has the through hole 10 that adapts with flexible stem external diameter of pipe.
With reference to Fig. 5, plug shape shielding foundry goods one end that connects defectoscope is provided with the groove 11 that is coupled with spherical shield cast(ing) surface radian, and the bottom portion of groove center has the through hole 12 that adapts with flexible stem external diameter of pipe.
During assembling, the pipe that at first flexibility had its source passes along the through hole that spherical shield foundry goods, cylindricality shield foundry goods bottom portion of groove center, note spherical shield foundry goods and cylindricality shielding foundry goods when wearing alternately, and two ends is spherical shielding foundry goods; The plug shape shielding foundry goods that secondly will connect defectoscope is positioned at both sides with the cylindricality shielding foundry goods that is connected probe, makes the shielding foundry goods cover flexible stem tube outside fully and forms shield assembly.
The utility model employing tungalloy that wearing quality is good, hardness is high, attenuation coefficient is high has been controlled the exposure to surrounding environment effectively as shielding material, has reduced protection distance, has guaranteed the operator and the public's x radiation x safety.Because ray operation control zone radius is little, can realize and other work post cross-operation, has improved operating efficiency; Because the stem tube shield device in the utility model has reelability, when the flaw detection operation, can carry out bending simultaneously, have the dirigibility of height according to on-site actual situations, very convenient to use.
