Description
Technical field
The present invention relates to a kind of radiographic inspection machine people.
Background technique
Radiographic inspection is one of common lossless detection method in the equipment Manufacture Process such as pressure vessel, shipbuilding, boiler.It is special
It is not in the seam inspection in Pressure Vessel Manufacture Process, the method for mainly using artificial detection at present, there are working efficiencies
It is low, influence follow-up work progress, large labor intensity and have the shortcomings that injury to human body.
Radiographic inspection has the following characteristics that
1. testing result can directly be recorded with egative film；
2. the projected image of defect can be obtained, Flaw discrimination is quantitative accurate；
3. volume flaw recall rate highest and the recall rate of area-type defect are influenced by factors；
4. being suitable for examining the workpiece of thinner thickness and being not suitable for examining thicker workpiece；
5. being suitable for detecting butt weld, detection fillet weld effect is poor, is not suitable for detecting plate, Cou material, forging.
Existing radiographic inspection main operational steps require determining, finishing workpiece surface, workpiece scribing line, as matter meter in addition to flaw detection
Selection with put, mark put, focus and the preparations such as the selection of exposure parameter outside, mainly include patch, booting examine
It surveys, piece darkroom disposal, establishing criteria is taken to comment piece, defective locations and shape determination etc..
During patch, operator needs to be measured with chalk, ruler, draw lines, and film is adsorbed on workpiece table
One section of weld seam of ray emission machine testing is opened, detection finishes after operator withdraws scene arrival operating room in the suitable position in face
Operator need to remove lower film afterwards, and number is in case subsequent darkroom disposal.
During ray detection, when carrying out radiographic inspection according to the principle of ray detection and requirements of the national standard, in order to
Thoroughly reflect workpiece joints internal flaw there are situations, should be according to the reasonable cloth of geometry of welding point form and workpiece
Transillumination method is set, according to the mutual alignment relation between radiographic source, workpiece and film, weld seam transillumination method is divided into longitudinal joint transillumination
Method, five kinds of method, both arms list shadow method and both arms slur method thoroughly in circumferential weld thoroughly outside method, circumferential weld.
Carrying out radiographic inspection detection using manual method, that there are working efficiencies is low, influences follow-up work progress and labor intensity
The disadvantages of big and larger to operator's actual bodily harm；Such as:
1. working efficiency is low
Traditional operating method require staff must carry out manual measurement fusion length, calculate film quantity, patch,
Thick and heavy X-ray radiation machine is moved to correct position and correct height.
When inside container to weld seam patch, due to can only once irradiate a film, operator has to once again
Primary pierce in container take piece, patch operation, and process is quite cumbersome and inefficiency.
Subsequent operation progress is influenced, the manufacturing process of pressure vessel usually first welded, by could be into after detection
Row repairing, welded attachment, pressure testing and the work such as paint, in ray detection, it is necessary to stop other work and special
Radiographic inspection room in detected, the poor efficiency of radiographic inspection seriously affects the manufacturing speed of pressure vessel.
2. large labor intensity
Pressure vessel ultrasonic examination generally at least needs two operators, an operator draws lines, patch,
The operation such as ray emission machine is carried, another is detected.When needing to be detected a flaw inside pressure vessel, also need to operate
Personnel, which enter inside container, to draw lines, patch, places the operation such as ray emission machine, and labor intensity is very big.
3. a pair human body has injury
It is required that the dose equivalent for receiving operator is no more than limit value while guaranteeing to complete radiographic inspection task,
And the absorbed dose of operator and other staff should be reduced as far as possible.
The major measure of protection has shielding protection, distance protection and protection of time.On-site photo can construction organization because of protection
Some problems, especially gamma-rays are brought, working efficiency and cost will affect to the strict control regulation of emitting isotope.

Steamboat 108 for example can be to be nested with and connect with the end of lower section slide bar 107.
Similarly, a steamboat (not shown) is also installed in two ends of each top slide bar 106 respectively, is acted on identical.
The radial section of top sliding rail 101 is also in T-shape, and it is convenient to cooperate with top slide bar 106.
107 sliding effect of lower section slide bar after putting on steamboat 108 is better than not covering sliding effect when steamboat.
In addition, elevating mechanism further includes No.1 driving part, for driving double scissor units 103 to realize lifting.Specifically,
No.1 driving part in the present embodiment can be drawn close or be carried out to centre by two lower section slide bars 107 of driving simultaneously
The mode of reverse motions, and then double scissor units 103 is driven to realize elevating movement.
Carry out reverse motions herein refer to that the direction of motion of two lower section slide bars 107 is opposite (i.e. simultaneously outward).
Lower mask body introduces No.1 driving part is how to be connected with lower section slide bar 107:
Elevating mechanism further includes crank and rocker mechanism, and No.1 driving part passes through crank and rocker mechanism and lower section slide bar 107
It is connected.
Due to there are two lower section slide bars 107, crank and rocker mechanism in the present embodiment also there are two.
As shown in fig. 6, each crank and rocker mechanism includes rotating bar 109 and each end of rotating bar 109 (two
End) it is respectively perpendicular a straight connecting rod 110 of installation, straight connecting rod 110 can be for example welded in rotating bar 109.
No.1 driving part is driving motor 111, such as can be stepper motor.
The quantity of driving motor 111 is four in the present embodiment, and every two is one group for driving the same rotating bar
109。
As shown in fig. 7, driving motor 111 is connected by shaft coupling 112 with the end of rotating bar 109.
The other end of two straight connecting rods 110 is connected by connecting rod 113, and the connecting rod 113 is parallel with rotating bar 109.
In addition, being equipped at least one curved rod between connecting rod 113 and lower section slide bar 107.
There are two the curved rods 114 being shown in FIG. 6, the present embodiment to the quantity of curved rod 114 with no restriction.
Connecting rod 113 and lower section slide bar 107 are circular pin, are respectively equipped with circle in two ends of curved rod 114
Rod aperture (not shown), and be nested in connecting rod 113 and lower section slide bar 107 respectively.
Under the action of four driving motor 111, two rotating bars 109 rotate respectively, and will be moved by curved rod 114
Power is transferred to corresponding lower section slide bar position, drives two lower section slide bars 107 inside simultaneously or moves out simultaneously.
The movement of above-mentioned two lower section slide bar 107 can be further driven to double realizations of scissor unit 103 again and rise or fall fortune
It is dynamic.
In addition, driving motor in the present embodiment can also only there are two, one of driving motor is for driving one
A rotating bar 109 (certain one end for being set to corresponding rotating bar 109), another driving motor drives another rotating bar 109.
Although this driving effect will be weaker than driving effect when four driving motors 111, it is real that function of the present invention is not influenced
It is existing.
In addition, elevating mechanism further includes elevating mechanism pedestal 115, lower section sliding rail 102 is installed on elevating mechanism pedestal 115
On.
Elevating mechanism pedestal 115 in the present embodiment for example can there are two, each correspondence of lower section sliding rail 102 is installed on one
On a elevating mechanism pedestal 115, mounting means for example can be and be bolted, and be also possible to be welded to connect.
