Using bolt (not shown) to connect between ramp 105, step 106 of getting on or off the bus, delivery platform 103, bottom is respectively mounted
There are castor (not shown) and lower margin (not shown).
Described door frame 203 is used for installing radiation source 201, detector 202, with inlet slope platform 101, terrace at entrance 102,
Export platform 104, exit ramp platform 105, step 106 of getting on or off the bus, delivery platform 103 coordinate and allow vehicle from door frame 203
In pass through, to realize scanning to full vehicle body.
Being designed as of described radiation source 201 pushes up illuminated, is arranged at door frame 203 top, it is possible to produce X-ray beam to detected
Object is scanned, and wherein said radiation direction is vertical with the conveying direction of described vehicle transportation device.
Described detector 202 is positioned at bottom door frame 203 and both sides, the detector 202 referred to as level detector 202 of bottom, and two
The detector 202 of side is referred to as side detector 202, is passed through the beam of detected object by detection detection, it is possible to realize quilt
Detection object detects.
Described inlet slope platform 101 and terrace at entrance 102 pass through described inlet slope platform 101 for tested vehicle along conveying direction
With terrace at entrance 102 hence into vehicle transportation device.
Described export platform 104 and exit ramp platform 105 pass through described export platform 104 for tested vehicle along conveying direction
With exit ramp platform 105 thus leave vehicle transportation device.
Described step 106 of getting on or off the bus lays respectively at terrace at entrance 102 and export platform 104 side, it is possible to facilitate driver upper and lower
Vehicle also leaves radiation area.
Described delivery platform 103 is arranged between terrace at entrance 102 and export platform 104, is divided into support platform 307 and defeated
Send machine (not shown) two parts.
Described support platform 307 is for supporting conveyer and the vehicle carried, in order to avoid stopping ray, to push up irradiation seam
It is divided into two parts for demarcation line, is separated by 20～30 millimeter, and is attached fixing under level detector 202.
Described circulation tug unit includes: motor, decelerator, power chain 304, power chain 304 axle, changed course sprocket wheel,
Changed course sprocket shaft, ring chain 305, dragging roller 303.For reduce drag resistance, described dragging roller 303 be set to roll shaft and
Roller two parts, described roll shaft two ends connect ring chain 305 respectively, and described roller is free to rotate, and roller can prop up car
Taking turns to drive vehicle to advance, there is the gathering sill 301 less than tested vehicle chassis described dragging roller 303 both sides.Described circulation drags
Unit uses motor, decelerator to drive power chain 304, changed course sprocket shaft circulation transmission；The chain link peace of ring chain 305
Dress drags roller 303 and moves with ring chain 305.After starting circulation tug unit, drag roller 303 and transport with ring chain 305
Dynamic, and automatically it is stopped at below suspension bridge unit 302, drag tested vehicle to wait.Tested vehicle passes through suspension bridge from import platform
Unit 302 enters delivery platform 103, drags roller 303 below bridge plate by bridge plate jack-up, and the roller dragging roller 303 props up car
Wd vehicle advances, and gathering sill 301 is prevented from wheel sideslip, drags roller 303 and is pushed at export platform 104 by wheel
Time, roller gradually departs from wheel, until turning to continuation to move to export platform 104, and is the most automatically stopped at suspension bridge device
Lower section, to wait next tested vehicle.When roller gradually departs from wheel, vehicle losing power stops, and has now detected.
Described suspension bridge unit 302 includes bridge plate and spring assembly, is positioned at the terrace at entrance 102 of described vehicle transportation device and defeated
Sending the junction of platform 103, spring assembly makes bridge plate often be in sling state, it is to avoid bridge plate contacts with the axle of changed course sprocket wheel and rubs
Wiping, when tested vehicle is entered conveyer by import platform, bridge plate is connected under pressure wheel and with delivery platform 103 phase, makes
Wheel steadily sails into；Bridge plate recovers to sling state afterwards；Simultaneously drag roller 303 can below bridge plate by bridge plate jack-up to pass through
Bridge plate so that dragging roller 303 can be with shuttling movement, in order to realize other vehicles to be checked checking continuously.
Described radiation source 201 is the linear accelerator being 250KV～300KV, 1MeV～6MeV.
Described radiation source 201 is arranged as central term photograph and side according to Double-visual angle, it is possible to reduce the stop to ray, level detector
202 lower sections being positioned at vehicle transportation device, vehicle transportation device is preferably fully disconnected above level detector 202 light slit,
This just brings difficulty to the design and installation of vehicle transportation device.During detection, tested vehicle is driven into defeated from import platform by driver
Sending platform 103, emptying gear, do not pull the hand brake, driver is got off by step 106 of getting on or off the bus afterwards, and circulation tug unit drags
Tested vehicle by X-ray beam complete detection, driver is got on the bus by step 106 of getting on or off the bus afterwards, car is left from.
The present invention is not limited to above-mentioned embodiment, in the case of without departing substantially from the flesh and blood of the present invention, people in the art
Member it is contemplated that any deformation, improve, replace each fall within the present invention claim record protection domain.
