Abstract
The utility model relates to a shutter mechanism for a sealed radioactive source, in particular to a shutter mechanism used for a radioactive source which is equipped with a strip steel thickness meter. The shutter mechanism used for a radioactive source which is equipped with a strip steel thickness meter comprises a cylinder, a piston rod connection component, a shutter and a cylinder driving piston rod connection component. The shutter is equipped above the radial emitting window and characterized in that the shutter mechanism also comprises two guide ways; the guide ways are installed on both sides of the top of a box on which a radioactive source pot in placed and the radial emitting window is opened; the shutter is a sliding shutter and installed on the guide ways where is close to the radial emitting window; one end of the shutter is fixed with a connection board and the connection board is connected with the piston connection component. The inside of the two guide ways is equipped with a V-shaped groove and correspondingly both sides of the shutter are equipped with a V-shaped convex. The cylinder is equipped with a spring inside which makes the cylinder piston rod extend out in normal state. The utility model has a comparatively simple structure and can be closed when the strip steel thickness meter is not used; the radial shielding property and the maintenance safety property of the utility model are comparatively excellent.
Description
(1) technical field
The utility model relates to a kind of tripper of sealing radioactive source, relates in particular to the radiographic source tripper that is used to the steel thicknessmeter.
(2) background technology
The opening and closing of the radiographic source tripper requirement ray window of band steel gamma thickness gauge must be satisfied measurement of correlation and require and ray security protection requirement.The online radioactivity survey of existing noncontact system, as radiographic source tripper with the steel gamma thickness gauge, the main cantilever baffle plate swing type shutter that adopts, promptly drive piston rod assembly by carrying out cylinder, drive shutter swing arm swing again, cover shutter baffle plate on the ray carrying shield by shutter swing arm drive, ray is penetrated in order to measure from the ray window.The weak point of this kind structure shutter is that ray window and shutter baffle plate gap are big, and the alpha ray shield effect is relatively poor; If x-ray apparatus is keeped in repair, owing to there is radiation leakage, will damage the maintainer, there is potential safety hazard in it.
(3) summary of the invention
The purpose of this utility model is to provide a kind of radiographic source tripper that is used to the steel thicknessmeter, and this radiographic source tripper structure is simple relatively, remains at off-position at thicknessmeter during without state, has alpha ray shield and maintenance safe preferably.
The utility model is achieved in that a kind of radiographic source tripper that is used to the steel thicknessmeter, comprise cylinder, piston rod coupling assembling, shutter, air cylinder driven piston rod coupling assembling, shutter is positioned at ray emission window top, it is characterized in that: described tripper also comprises guide rail, and guide rail is installed in storing ray carrying shield and has on the both sides, casing top of ray emission window; Shutter is the slidingtype shutter, and shutter is installed in is close to the ray emission window on the guide rail, and shutter one end installs web joint, and web joint connects the piston rod coupling assembling.
Described two guide rail inboards have V-shaped groove, and corresponding shutter both sides have the V-arrangement convex surface.
In the described cylinder spring is housed, cylinder piston rod is stretched out under normal conditions.
The utility model is that the slidingtype shutter is housed on the ray emission window, and shutter is embedded in the V-shaped groove guide rail and slides, thereby has guaranteed that shutter and ray emission window have tighter sealing, avoid ray to leak; And the executive component cylinder adopts stretches the type active cylinder in advance, make cylinder under normal conditions piston rod stretch out, guarantee that shutter remains at off-position when free state, improved tripper install, maintenance and the security when using.
The utility model structure is simple relatively, remains at off-position when being with the steel thicknessmeter without state, has alpha ray shield and maintenance safe preferably.
(4) description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is used to radiographic source tripper structural representation with the steel thicknessmeter for the utility model;
Fig. 2 is the A-A view of Fig. 1;
Fig. 3 is the B-B view of Fig. 1.
Among the figure: 1 cylinder, 2 piston rod coupling assemblings, 3 shutters, 4 ray emission windows, 5 ray carrying shields, 6 guide rails, 7 outer containers, 8 web joints, 9 casings.
(5) embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, a kind of radiographic source tripper that is used to the steel thicknessmeter comprises cylinder 1, piston rod coupling assembling 2, shutter 3, guide rail 6.Cylinder 1 promptly is equipped with spring for stretching the type single-acting cylinder in advance in cylinder 1, cylinder piston rod is stretched out under normal conditions.Cylinder 1 piston rod coupling assembling 2; Shutter 3 is the slidingtype shutter, and shutter 3 is installed in is close to the ray emission window on the guide rail 6, and shutter 3 one ends install web joint 8, and web joint 8 connects piston rod coupling assembling 2.Guide rail 6 is installed in storing ray carrying shield 5 and has on the both sides, casing 9 top of ray emission window 4, two guide rail 6 inboards have V-shaped groove, corresponding shutter 3 both sides have the V-arrangement convex surface, and shutter 3 fixes at ray emission window 4 places, and shutter 3 can slide along V-shaped groove guide rail 6.Whole radiographic source tripper is installed in the outer container 7.
By controlling the piston rod retraction that pneumatic element makes cylinder 1, pulling shutter 3 is opened ray emission window 4 during work.When not working, discharge the pressurized air in the cylinder 1, then stretch out under the piston rod effect of portion's spring within it, shutter 3 is closed ray emission window 4.The shift motion of shutter 3 is cylinder 1 stroke, the selection of cylinder 1 stroke than the diameter of ray emission window 4 bigger get final product.Because shutter 3 is fixed on ray emission window 4 places closely by the V-shaped groove guide rail 6 of both sides, what make that it can be tight shelters from ray emission window 4, has avoided leaking of ray.And owing to adopted and stretch type single-acting cylinder 1 in advance, can guarantee that shutter 3 (during off position) when free state remains at off-position, improved install, maintenance and the security when using.
The utility model structure is simple relatively, remains at off-position when being with the steel thicknessmeter without state, has alpha ray shield and maintenance safe preferably.
