Description
Technical field
The utility model is related to X-ray rays safety detection apparatus accessory field, more particularly to a kind of collimater and its mounting structure.
Background technology
Screening machine ray collimating structure is that two pieces of lead-antimony alloy board components that can block ray are mounted side by side on base plate, two
Close gap is left in the middle of block stereotype passes through useful ray, and this structure is typically mounted in the box body of shielding ray, because can not
Process and assemble error and the bearing structure deformation avoided, collimation mechanism typically needs left and right adjustment so that the main energy beam face of ray passes through
Gap in the middle of two blocks of stereotypes is irradiated on detector panel.
Collimating structure fixed form typically has two kinds, a kind of as shown in figure 1, collimater 1 is completely disposed in shielding box 2, uses
Screw rod 3 is adjusted and fixed.The mounting means of screw rod regulation causes collimater dismounting very inconvenient, after need to shielding box integrally be pulled down
It can just pull down, be operated when collimating slit width is adjusted during equipment debugging highly difficult.It is another as shown in Fig. 2 the two ends of collimater 1
It is screwed, and is adjusted with left and right Top fastening screw 4 outside shielding box 2.Collimater two ends are spilt outside shielding box and by screw
Fixed, when at side view angle, light path shielding box is vertically-mounted, the left and right Top fastening screw of bottom is located at equipment lowermost end, and people can not stand
Operation, while device bottom is often disposed with electric elements, the operating space of left and right Top fastening screw is blocked, so that need to be by electrical equipment
Regulation space can be just conceded after element dismounting.
Collimater in above two collimating structure fixed form causes length than logical because being arranged in parallel with channel wall
Shielding collimating effect could be covered whole passage by the long cross direction size length in road (second of arrangement) or slightly short (the first arrangement).
For big passage rays safety detection apparatus, this can cause, and collimator length is long, and weight is excessive, is easily deformed, while collimating slit width one
As in 1mm or so, ray width after collimating slit can form certain magnification ratio because of concrete structure.As shown in figure 3, projecting
Beamwidth L4=L3 × L2/L1 of end detector panel 5, in various actual types, L2/L1 is slightly larger than 1, if collimating slit is
1mm, then L4 be also slightly greater than 1mm.And the radiation exposure width on the detector panel 6 of remaining position is significantly greater than end detector
Plate, irradiating width is narrow to be easily caused detector panel crystal, and collimating slit, target spot three alignment is difficult regulation.(in Fig. 3, L1：Ray machine
Target spot is away from collimater distance, L2：Ray machine target spot is away from detector panel crystal distance, L3：Collimating slit width, L4：Ray is by collimation
Detector panel width is projected after seam.)

Install after finishing, top cover 308 is inserted on left and right baffle plate 302,303.
The detailed process that the collimater 10 is attached on shielding box 300 is as follows：
As shown in Figure 7 and Figure 8, first collimater 10 is inserted into shielding box along supporting plate 305, T-shaped base plate in collimater 10
100 transverse slat is placed in the groove 309 of left and right baffle plate 302,303, in place after, in T-shaped base plate 100 on transverse slat 104 with riser
The flange 101 of 103 edges being connected and the clamping of position-limited edge 310.Now, as shown in fig. 6, T-shaped base plate 100 is resisted against supporting plate
On 305, the gap in collimater between two stereotypes 200 is positive towards the first ray opening 3011 and just to the second ray opening
The both sides of transverse slat 104 are also inserted into left and right damper box 306,307 in 3051, and T-shaped base plate 100.As shown in figure 8, working as collimater
10 when needing to adjust to the right, the lock nut 402 that adjusting screw 401 is locked in left and right damper box 306,307 is unclamped, by two
Adjusting screw 401 is adjusted to the right simultaneously, and the adjusting screw 401 in left damper box 306 withstands on the T-shaped left side flange 101 of base plate 100
On, T-shaped base plate 100 is pushed up to the right, after being adjusted in place, two adjusting screws 401 adjusted to the middle part of shielding box 300 simultaneously
Section, clamps T-shaped base plate 100, finally tightens lock nut 402；When collimater 10 needs to adjust to the left, left and right regulation is unclamped
The lock nut 402 of adjusting screw 401 is locked on box 306,307, two adjusting screws 401 are adjusted to the left simultaneously, right regulation
Adjusting screw 401 on box 307 is withstood on the T-shaped right side flange 101 of base plate 100, T-shaped base plate 100 is pushed up to the left, when being adjusted to
Behind position, two adjusting screws 401 are adjusted to the middle part of shielding box 300 simultaneously, T-shaped base plate 100 is clamped, finally tightens lock nut
402.After adjustment is finished, two fixing screws 403 pass through after the fixing hole 102 in left damper box 306 and T-shaped base plate 100 and solid
Determine nut 404 to be spirally connected, then two fixing screws 403 through after the fixing hole 102 in right damper box 307 and T-shaped base plate 100 with it is solid
Determine nut 404 to be spirally connected, so as to complete the fixation of collimation device 10.Finally, as shown in fig. 6, by the buckle closure of top cover 308 in groove 309
On, so as to just complete the installation of collimation device 10.Opposite step is then used when dismantling collimater 10.
Base plate is T-type structure in above-mentioned collimater 10 and its mounting structure, collimater 10, is both provided for two stereotypes 200
Enough installing spaces, shorten the length of stereotype and are easy to collimater 10 to be inserted to reduce deformation, again, so that should
Collimater 10 can directly oblique cutting on shielding box 300, facilitate the dismounting and regulation of collimater 10, and operating personnel can stand
In the case of directly operate, it is not only convenient but also laborsaving.The collimater angle-inserting type mounting structure is also not take up device bottom electrical appliance arrangement
Space, while it is small to solve end detector panel area of illumination, the problem of being difficult regulation.As shown in figure 9, after collimater is tilted, end
(as shown in Figure 3) broadens when portion's detector panel 11 is placed vertically by radiation exposure face L4 (=L3 × L2/L1) compared with collimater, makes this
Plate can easily be accommodated.(in Fig. 9, L1：Ray machine target spot is away from collimater distance, L2：Ray machine target spot is away from detector panel crystal distance, L3：It is accurate
Vertical masonry joint width, L4：Ray projects detector panel width after collimating slit.)
