Abstract
The invention discloses the control device of X-ray beam in a kind of green channel detecting system, precollimator has only released our project by slit needs the fan-shaped x-ray beam at position, when we need X-ray to penetrate time, gap on slip lead device is by the most mobile slit being directed on precollimator, when need not X-ray injection when, the slit that slip lead device blocks on precollimator plays shield effectiveness, outside slip lead device, add one piece of periphery again fix lead device, slit and the slit of precollimator on the fixing lead device in this periphery align, so X-ray can only be fixed lead device slit from outermost and be penetrated.The invention provides a kind of in the case of X-ray is not turned off, cut off beam quickly and accurately, beam is penetrated by appointment region, and meets when cutting off beam, the control device of X-ray beam in x-ray dose safety, the green channel detecting system not exceeded standard.
Description
Technical field
The invention belongs to transmission imaging technique skill of Non-Destructive Testing in traffic and transportation management system
Art field, particularly relates to the control device of X-ray beam in a kind of green channel detecting system.
Background technology
In recent years, executing of highway fresh and alive agricultural byproducts green channel policy is set up along with country
OK, green channel detection equipment also emerges in an endless stream.One utilizes X-ray transmission formula green to lead to
Road Vehicle analyzer is little with radiation dose, and penetration power is strong, and life cycle is long, even if accident occurs,
Surrounding and operator the advantages such as impact be will not be produced and traffic department and Ministry of environment obtained
The accreditation of door.It is to utilize ray transmission imagery principle, and the fan-ray beam that X-ray machine sends is worn
Closure compartment and goods inside, received by opposite side fixed linear array detector thoroughly.
Owing to article different densities is distributed, different to the degree of absorption of ray, the signal of detector output
Intensity is the most different, is shown on computer display screen by power unlike signal after image procossing, can
Know tote product in closure compartment.Owing to vehicle is full-automatic work by X-ray detecting equipment
Operation mode, when driver driving vehicle directly passes through scan channel, it is not necessary to stopping, this must need
The device of ray safety control reliably dodges the driver's cabin of detection vehicle automatically, and only to tested
The compartment of measuring car is scanned.X-ray dose needs 2-4s from starting stable output, so
The presence or absence of X-ray can not be controlled by switch high-pressure within the short time that vehicle passes through.
This needs to install a protection dress can quickly opened, close in the front of fan-shaped x-ray beam
Put.
Summary of the invention
In order to solve the environmental pollution that in prior art Green channel detection system, X-ray is brought
With driver human safety issues, the invention provides a kind of feelings being not turned off in X-ray
Under condition, cut off beam quickly and accurately so that beam is by specifying region injection and full
Foot is when cutting off beam, in x-ray dose safety, the green channel detecting system not exceeded standard
The control device of X-ray beam.
In order to solve the problems referred to above, the technical solution used in the present invention is:
The control device of X-ray beam in a kind of green channel detecting system, including X-ray machine, in advance
Collimator connecting plate, it is characterised in that: also include electric magnet, floating junction, slip lead device

Detailed description of the invention
Below in conjunction with the accompanying drawings, the present invention will be further described.
As it can be seen, the control device of X-ray beam in a kind of green channel detecting system, including
X-ray machine 17, precollimator connecting plate 20, electric magnet 1, floating junction 2, slip lead device
Connecting plate 13, peripheral fixing lead device 14, slip lead device 15 and precollimator 16, institute
State X-ray machine 17 and be installed to inside two pieces of precollimator connecting plates 20 by fixing screw 19,
Connect on one piece of precollimator connecting plate 20 inwall wherein and have electric magnet 1, described electric magnet 1
Free end be connected, at X-ray machine with slip lead device connecting plate 13 by floating junction 2
It is provided with precollimator 16 on 17, precollimator 16 is provided with guide rail 7, at guide rail 7
On be provided with the slide block 8 that slides along guide rail 7, described slip lead device 15 is by sliding
Lead device connecting plate 13 is fixed on slide block 8, and described periphery is fixed lead device 14 and is positioned at slip
Outside lead device 15, and it is fixedly connected on precollimator 16, fixes lead device in periphery
The outer layer stereotype fixed plate of fixation it has been provided with outside 14.Lead device is fixed in described periphery
The gap of 14 is directed at all the time with the gap of precollimator 16, described slip lead device connecting plate 13
Slip lead device 15 is driven to move along guide rail 7.
The control device of X-ray beam in green channel detecting system, it is desirable to X-ray machine 17 sends
Be fan beam, on market, the type ray machine is all cylindrical, our X-ray machine to be given
Doing the precollimator 16 of a cylindrical shape outside 17, precollimator 16 needs casting just can complete,
So cost is the biggest.In view of the low melting point of lead, the easily physical characteristic of welding, we are in advance
Collimator design becomes rectangular shape (such as Fig. 3), and the fladellum radiation areas of X-ray machine are very
By force, such precollimator wire outlet part requires stereotype 20mm thicker than other position, after having welded again
Open orthogonal slits in the position needed and guarantee that fan beam can penetrate.
As shown in Figure 4, Figure 5, slip lead device 15 and periphery are fixed lead device 14 and are all welded
L-shaped shape also cuts out gap, in order to prevent lead oxidized, needs to wrap up one layer in lead periphery not
Rust steel protective cover 11.
