Embodiment
As shown in fig. 1, the radiation testing device for human body safety inspection according to the present invention comprises: for sending the ray generator 1 of ray; For receiving the detector 7 of the ray that described ray generator sends; Be connected with ray generator 1, for the steel band 4 of lifting ray generator 1, be connected with detector 7, for the steel band 5 of lifting detector 7; And windlass 11, described windlass 11 is by steel band 4 and 5 synchronization lifting ray generators 1 and detector 7, and while ray generator 1 and detector 7 be interval preset distance in the horizontal direction.
As shown in fig. 1, for the radiation testing device of human body safety inspection, also comprise: guide rail 2, guide rail 2 carries out lifting for navigation rays generator 1; And guide rail 6, described guide rail 6 is for guiding detector 7 to carry out lifting.
As shown in fig. 1, steel band 4 and 5 is walked around angle sheave 3 and is connected with one end of steel band web member 9, one end of steel band 10 is connected with the other end of steel band web member 9, the other end of steel band 10 is connected with the windlass 11 that is arranged on the radiation testing device bottom of safety inspection, so that by windlass 11 synchronization lifting ray generators 1 and detector 7.
Windlass 11 has comprised reuses reel, and has driven the motor of reusing reel, and steel band 10 is reused reel and is connected with rising.The thickness of steel band can be from 0.1mm～1mm, the gauge thickness of the present embodiment steel band is 0.2mm, the width of steel band is determined by the size of the load for lifting ray generator 1 and detector 7, the elastic deformation amount that this power producing due to acceleration and deceleration while being mainly the startup of elimination steel band causes steel band, numerical value is from 20mm～200mm, and the present embodiment is 30mm.
For guaranteeing better the synchronism of operation, ray generator 1, receiver 7 and steel band web member 9 can move along guide piece, and guide piece can be guide rail, axle or other devices.Three guide rails that the present embodiment adopts, ray generator 1 thus, and receiver 7 and steel band web member 9 move along guide rail.
In above-mentioned example, adopted windlass, as selection, replaced windlass, can adopt and comprise nut, the leading screw coordinating with nut, and the drive unit that drives the motor of leading screw rotation.In this case, steel band 4 can directly be connected with nut with 5, by leading screw rotating drive nut, moves up and down, and thus, drives ray generator 1 and receiver 7 to move up and down.In addition, replace nut and leading screw, can adopt rack and pinion.
In addition, in the above-described embodiments, windlass 11 is arranged on bottom, but windlass 11 also can be arranged on a residing position of angle sheave 3, and now this angle sheave 3 is replaced by windlass 11.In addition, windlass 11 also can be arranged on the optional position of the top of guide rail 2,6,8.
Adopt the radiation testing device for human body safety inspection of the present invention, during human body safety inspection, can adopt people's transfixion, ray generating device and detector operation, or people's motion, and ray generating device and receiving trap are motionless.The present embodiment adopts people transfixion, ray generator and detector vertical movement.
In addition,, for preventing that steel band motion from time laterally skidding, the present embodiment is made cydariform mode by belt wheel, as shown in Figure 2.
For the diameter of belt wheel, can adopt 400～1000 times of thickness of strips, 700 times of the thickness of strips that the present embodiment adopts.
When windlass rotates, steel band can be wrapped on cylinder, because the impact of thickness of strips can cause coiling diameter to become large, can adopt the method that reduces thickness of strips and increase drum diameter to solve.The present embodiment adopts and reduces thickness of strips, and the drum diameter of appropriateness increase simultaneously makes to be wound around the number of turns and reduces, thereby reduces as much as possible this error.
Can increase protective device, prevent from that steel band from particular cases rupturing to cause ray generator and detector to damage, this protective device can adopt a set of wire rope or steel band.Can increase accordingly a set of protecting device for wire rope with steel band, while normally moving, wire rope is inoperative, and when steel band surprisingly ruptures, wire rope is tightened, thereby protection institute tractive load is not damaged.
As follows according to the principle of work of the radiation testing device for human body safety inspection of the present invention:
Windlass 11, by driven by motor, pulls steel band part 10, and steel band web member 9 moves along guide rail 10, pulls steel band 4 and steel band 5 simultaneously, and steel band 4 pulls ray generator 1, and steel band 5 pulls detector 7, and ray generator and detector move along guide rail 2 and guide rail 6 respectively.As mentioned above, this system and device is to adopt steel band as driving member, the power of windlass is passed to another two steel bands of both sides by web member by a steel band, thereby guarantees the synchronism of two lateral load liftings.Radiographic source sends ray simultaneously, and the ray that radiographic source sends becomes fan-shaped plan bundle after collimating apparatus, through after being examined human body, enters detector window.After several milliseconds of the radiation profile data of the image " every a line " that detector gathers, be just recorded in storer, after the end of scan, by the image after fast processing, be presented on display.
In addition,, although adopted steel band in above-described embodiment, also can adopt the replacement steel bands such as belt of making such as band rope, synthon.
Moreover, although in above-described embodiment, to have described radiation testing device inspected object has been carried out to radiant image, this device also can be for obtaining the data about inspected object.
