Abstract

The utility model relates to a device used in radiography safety detection field, in particular to a two-DOF (Degree of Freedom) portable X ray imager. According to the technical scheme of the utility model, the two-DOF ray imager comprises an image detector and a pulsed X ray machine. The detecting faces of the image detector and the pulsed X ray machine are arranged face to face. The image detector is fixedly connected at one end of a first bracket, the other end of which is spliced with one end of a two-way output shaft of a rotating device, and the other end of the two-way output shaft is spliced with one end of a second bracket. The pulsed X ray machine is fixedly arranged at one end of a slide bar, the other end of which is spliced with the other end of the second bracket, a moving mechanism which moves linearly up and down is arranged between the end of the second bracket and the end of the slide bar. The two-DOF ray imager has the advantage that the two-DOF ray imager can reduce imaging dead zones, realize scanning in different angles, and be used in complicated environments like in a slit or on a slope.

Description

Two degrees of freedom Portable X-ray imager

Technical field

The utility model relates to the device in a kind of radiant image safety detection field, especially a kind of two degrees of freedom Portable X-ray imager.

Background technology

Along with the deterioration of domestic and international security situation, more and more higher to colony's security requirement in departments such as public security, customs, the Portable X-ray imager provides the method for easily the not clear case and bag in scene being carried out fluoroscopic examination, becomes indispensable equipment.

Find through literature search prior art, x-ray imaging instrument described in the Chinese utility model patent of Wang Jingjin etc. " wireless portable wedge shape detector x-ray imaging instrument " (patent No. 200320124667.X) is except that using pulse X-ray machine, image detector, wireless receiver and computing machine composition system, improved detector structure, dwindled the volume of detector, successful acquisition thin wedge shape outward appearance, realized having the Portable X-ray detection instrument of characteristic such as the imaging dead band is little.But because detection instrument integral body is rigid structure, can not adjust, still have suitable imaging dead band, can't scan by translation-angle, can't under complicated applications environment such as slit, use flexibly with applied environment.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of two degrees of freedom Portable X-ray imager that scans, can use under complex environments such as slit, slope as dead band, realization translation-angle that is reduced to is provided.

The technical scheme that provides according to the utility model, described two degrees of freedom Portable X-ray imager, comprise that the test side faces one another the image detector and the pulse X-ray machine of setting, image detector is fixedly connected on an end of first support, the other end of first support and the output shafts of wheelwork one end are pegged graft, one end of the output shafts other end and second support plugs, pulse X-ray machine is fixedly installed on sliding bar one end, the other end of the sliding bar other end and second support plugs, and is provided with between second bracket end and sliding bar end, following linear moving mechanism.

Described wheelwork is included in worm reduction gear and the rotary drive motor thereof that is provided with on the output shafts.Described upper and lower linear moving mechanism is included in the tooth bar that fixedly installs on the sliding bar, on second support, be rotatably connected to the gear of creeping with the tooth bar engagement, the gear of creeping is fixed on the output shaft of speed reduction unit, the output shaft of speed reduction unit is rotatably connected on second support, and speed reduction unit drives by sliding drive motor.Described first support and second support be at right angles shape bending all.

The utlity model has and be reduced to the advantage that scans, can under complex environments such as slit, slope, use as dead band, realization translation-angle.

Embodiment

The utility model is described in further detail below in conjunction with concrete drawings and Examples.

As shown in the figure: this two degrees of freedom Portable X-ray imager, comprise that the test side faces one another the image detector 1 and pulse X-ray machine 2 of setting, image detector 1 is fixedly connected on an end of first support 4, the other end of first support 4 and the output shafts of wheelwork 8 one ends are pegged graft, one end of output shafts 8 other ends and second support 5 plugs, pulse X-ray machine 2 is fixedly installed on sliding bar 3 one ends, the other end of sliding bar 3 other ends and second support 5 plugs, and is provided with upper and lower linear moving mechanism between second support, 5 ends and sliding bar 3 ends.

Described wheelwork is included in worm reduction gear 7 and the rotary drive motor 6 thereof that is provided with on the output shafts 8.

Described upper and lower linear moving mechanism is included in the tooth bar 11 that fixedly installs on the sliding bar 3, on second support 5, be rotatably connected to the gear 12 of creeping with tooth bar 11 engagements, the gear 12 of creeping is fixed on the output shaft of speed reduction unit 10, the output shaft of speed reduction unit 10 is rotatably connected on second support 5, and speed reduction unit 10 drives by sliding drive motor 9.

Described first support 4 and second support 5 be at right angles shape bending all.

The present invention includes image detector 1, pulse X-ray machine 2, sliding bar 3, first support 4, second support 5, rotary drive motor 6, worm reducer 7, output shafts 8, slide drive motor 9, speed reduction unit 10, tooth bar 11 with creep gear 12.Pulse X-ray machine 2 is fixed with sliding bar 3 lower ends, and image detector 1 and first support, 4 lower ends are fixed.Rotary drive motor 6 is installed on the reducer of turbodrill 7, and reducer of turbodrill 7 has the output shafts 8 of perforation, and the two ends of output shafts 8 are fixedly connected first support, 4 upper ends and second support, 5 upper ends respectively.First side of reducer of turbodrill 7 and reducer of turbodrill 7 second sides provide the plane of being grasped by external device (ED) jointly.Slide drive motor 9 and be installed on the speed reduction unit 10, the gear of creeping (12) is installed on the output shaft of speed reduction unit 10.Tooth bar 11 is fixed on sliding bar 3 inside.Sliding bar 3 upper ends are enclosed within second support, 5 lower ends, can move according to straight line about the gear motion of the gear 12 of creeping, tooth bar 11.
