Embodiment
Below in conjunction with accompanying drawing the present invention is done further explanation.
Structure of the present invention is as shown in Figure 1, when large-scale relatively tubular weldment radiographic inspection, the radioactive source probe is fixed in the present invention.Structure of the present invention is following: this support comprises two carrier units that structure is identical; Each carrier unit comprises trailing arm B or D and transverse arm A or C; The end of trailing arm B is fixedly connected perpendicular to the midline position of transverse arm A and with transverse arm A; Perhaps the end of trailing arm D is fixedly connected perpendicular to the midline position of transverse arm C and with transverse arm C, and promptly trailing arm B and transverse arm A are the inverted T shape arm, or trailing arm D and transverse arm C are the inverted T shape arm; Two ends of the other end of trailing arm B and the A of transverse arm are provided with homoaxial sleeve 1,2,3; Sleeve 1,2,3 is all vertical with transverse arm A with trailing arm B; In like manner; Two ends of the other end of trailing arm D and the C of transverse arm are provided with homoaxial sleeve 4,5,6, and sleeve 4,5,6 is all vertical with transverse arm C with trailing arm D.
The same pipe fitting 10 of sleeve 4 sockets of the other end of two carrier units sleeve 2 and another transverse arm C through transverse arm A forms cradle heads; Make to form angle between trailing arm B and the D that sleeve 3 and the same pipe fitting 8 of 6 sockets with two trailing arm B and D forms support then; Pipe fitting 8 in the said trailing arm sleeve 3 and 6 is used to place the source conduit 9 of radioactive source probe, thereby fixedly radioactive source is popped one's head in.
The transverse arm A of said support, the sleeve of C 1,2,4,5 all are positioned on the inwall of tubular weldment 7, and the pipe fitting 8 of sleeve 3,6 sockets of trailing arm B, D is the shaft core position of weldment 7, and promptly the radioactive source probe is arranged in the shaft core position of tubular weldment 7.This supporting structure is simple and reliable, and is convenient to use, and extensively is suitable for for the different large-scale tubular weldment of internal diameter.
Said trailing arm B, D are telescopic structure, can regulate the length of trailing arm B, D according to different weldment 7 internal diameters.
The bottom of said sleeve 1,2,4,5 is provided with roller, can make the light translation of support; Roller is provided with arrestment mechanism, and the pair roller braking was to guarantee unexpected moving to occur after support moved to correct position.
The barrel dliameter of the sleeve 1,2,4,5 of said transverse arm A, C is all identical, and the barrel dliameter of the sleeve 3,6 of trailing arm B, D is all identical.In order to simplify the production technology of this support, the barrel dliameter of sleeve all can be arranged to identical barrel dliameter.
When forming support by two identical carrier units of structure; The wherein a pair of sleeve in transverse arm end position is provided with cradle head between two carrier units; Through cradle head carrier unit is relatively rotated, the angle that forms between the two stands unit is variable to adapt to the inwall of different inner diameters weldment.Therefore, in the time of installation, the pipe fitting of transverse arm sleeve can be installed earlier, and then the pipe fitting of trailing arm sleeve is installed, form cradle head.
This structure Design principle is: its intersection point of the perpendicular bisector of any two uneven strings must be the center of circle on the circle.According to this principle, extend two trailing arm B, D find weldment 7 when weldment 7 axial projections are intersected axle center, according to the simple plane geometrical principle, just can easily the radioactive source probe be arranged in the shaft core position of tubular weldment 7.Fix after backing positions, trailing arm B, D elongation configure, then can use the pipe fitting 8 of suitable external diameter that the relevant sleeve unification is passed, guarantee integrally-built stable.
Arrangement when the present invention uses is shown in Fig. 2-3.During work, elder generation is arranged in support 11 near the weld seam of large-scale weldment 7 by direction as shown, and all rollers all contact with weldment 7 inwalls, and promptly support relies on angle self-adaptation weldment 7 internal diameters that form between the two stands unit.Regulate the length of support two trailing arm B and D simultaneously,, and make these sleeves 3 and 6 coaxial with weldment 7 until the elongation of two trailing arm B and D top sleeve 3 and 6 locking trailing arm B and D when the axial projection of weldment 7 is overlapping.For guaranteeing positioning stablity; Arrange another support 12 by same order near above-mentioned support 11; And pass the sleeve at carrier unit cradle head place, each sleeve that pipe fitting 8 passes the trailing arm top with pipe fitting 10, to strengthen integrally-built stability (can increase and decrease the secondary quantity of support) according to actual conditions.This moment source conduit 9 being stretched into pipe fitting 8 stretches out from front end until probe.Because support is furnished with roller, promote holder combination and can adjust integral position, the overhang of the relative pipe fitting of also fine-tuning probe (8), the final probe that guarantees unobstructedly is positioned on the weldment section of weld joint, and the locking roller is to prevent unexpected generation of moving.So far radioactive source probe positioned can be carried out radiographic inspection work.
