Background technology
In the place that safety check is had relatively high expectations; Often need carry out X-ray scanning to personnel's whole body, whether inspection carries prohibited items, for example on the security check passage of customs; Current general employed digital X ray equipment; Whether employing checks Poison to personnel's body scan from top to bottom, but existing X ray total body scan unit inside has complicated transmission, could realize contraposition accurately; And complicated mechanism causes high manufacturing cost and overweight volume undoubtedly, has brought obstacle also for the popularization and application of equipment.
Summary of the invention
The present invention has overcome above-mentioned shortcoming, and a kind of simple in structure, contraposition Exact Number drug-detecting machine is provided.
The present invention solves the technical scheme that its technical matters takes: a kind of digital drug-detecting machine; Comprise x ray generator and X ray receiver; Also comprise elevating mechanism; Said elevating mechanism comprises a ring-shaped synchronous belt and driven pulley; Said ring-shaped synchronous belt is bent into the three double-deck parts through driven pulley, and wherein the two parts at two ends are parallel to each other, and the said ring-shaped synchronous belt of first driven by motor rotates between each driven pulley; On parallel two parts of ring-shaped synchronous belt and homodromous respective segments, be connected with first device and second device respectively, said first device and second device are respectively said x ray generator and said X ray receiver, or are respectively said X ray receiver and said x ray generator.
Said device also can comprise synchronous scanning mechanism; Said synchronous scanning mechanism comprises second motor and by the scanning driving-belt of second driven by motor; Said first device is connected with said scanning driving-belt; Be respectively arranged with on said first device and second device and be fixedly connected piece; Synchronous scanning bar is connected across two and is fixedly connected between the pieces, and can with the said second device coaxial rotation, said scanning driving-belt is installed in respectively on parallel two parts of ring-shaped synchronous belt and the homodromous respective segments with said second device.
Said synchronous scanning mechanism also can comprise a curved track, and said first device connects said curved track, and can be along said curved track swing.
Said fixed connection piece can be the slip cap of hollow, and the rotating shaft position of said synchronous scanning bar is fixed, and said synchronous scanning bar also comprises two vertical bars, and said vertical bar can slide in said slip cap.
In the elevating mechanism that the present invention adopted, ring-shaped synchronous belt is closed ring, and by first motor direct-drive, the up-down start-stop is quick, and synchronously accurately, and lifting structure is simple, and overall weight is light.In addition, when the motion of second driven by motor scanning driving-belt, first device swings back and forth under the drive of scanning driving-belt; And under the drive of synchronous scanning bar, make second device and the coaxial swing of synchronous scanning bar; Thereby realize first device and the synchronous scanning campaign all the time of second device, and, because said first device is connected on the curved track; Can form circular arc along curved track moves; Satisfy first device and second device over against requirement, also further satisfied the scanning motion needs and risen soon, stop soon, and in even, the stable requirement of scanning process medium velocity.Thereby performance enormous function in fields such as safety check, drug law enforcement.

Embodiment
Digital drug-detecting machine disclosed by the invention is made up of the relatively independent gear train of two covers, and one is to realize moving up and down the elevating mechanism of contraposition, and another is the synchronous scanning mechanism of realization horizontal scanning images acquired.
As shown in fig. 1; Said elevating mechanism comprises a ring-shaped synchronous belt 3 and a plurality of driven pulleies 4; Said ring-shaped synchronous belt 3 is bent into the three double-deck parts through driven pulley; The promptly and left and right sides, wherein two parts of the left and right sides are parallel to each other, and first motor 5 drives said ring-shaped synchronous belt 3 in 4 rotations of each driven pulley.First device 1 is installed in respectively on parallel two parts of ring-shaped synchronous belt and the homodromous respective segments with second device 2.Because what adopted is rings of a sealing with 3 synchronously, thereby it is quick to have reached the up-down start-stop, requirement accurately synchronously.And motor 5 directly drives ring-shaped synchronous belt 3 goes up and down left and right sides equipment, need not counter weight construction, makes lifting structure simple, and overall weight is light, does not also need the aeroembolism damping, meets the start-stop requirement of going up and down fast.
Like Fig. 2, shown in 3; Said synchronous scanning mechanism comprises second motor 6 and by the scanning driving-belt 7 of second driven by motor, said first device 1 is connected with said scanning driving-belt 7, is respectively arranged with on said first device 1 and second device 2 and is fixedly connected piece 10; A synchronous scanning bar 9 is connected across two and is fixedly connected between the piece 10; And can with the said second device coaxial rotation, said fixed connection piece 10 is slip caps of hollow, rotating shaft 91 stationkeeping of said synchronous scanning bar; Said synchronous scanning bar also comprises two vertical bars 92, and said vertical bar 92 can slide in said slip cap.Said synchronous scanning mechanism also comprises a curved track 11, and said first device 1 connects said curved track 11, and can be along said curved track 11 swings.Said scanning driving-belt 7 is installed in respectively on parallel two parts of ring-shaped synchronous belt and the homodromous respective segments with said second device 2.
When motor 6 drove 7 motions of scanning driving-belt, first device 1 swung back and forth under the drive of scanning driving-belt 7, and drove synchronous scanning bar 9 along rotating shaft 91 swings through being fixedly connected piece 10; The swing of synchronous scanning bar 9 drives second device 2 and the 9 coaxial swings of synchronous scanning bar again; Thereby make first device 1 realize the synchronous scanning campaign with second device 2 all the time, and, because said first device 1 is connected on the curved track 11; Can form circular arc along curved track 11 moves; Satisfy first device 1 and second device 2 over against requirement, also further satisfied the scanning motion needs and risen soon, stop soon, and in even, the stable requirement of scanning process medium velocity.In addition, for reducing the heavy burden of ring-shaped synchronous belt 3, synchronous scanning bar 9 to do the swing of horizontal direction, can not move up and down, and first device 1 and second device 2 can move up and down with jacking gear only; In addition, are slip caps of hollow with first device 1 with the fixed connection piece 10 that second device 2 is connected, let rotating shaft 91 stationkeeping of said synchronous scanning bar 9; Can let two vertical bars 92 of synchronous scanning bar 9 slide therein; Like this, when first device 1 and second device 2 move up and down with elevating mechanism, do not influence the horizontal scanning campaign; So elevating mechanism and synchronous scanning mechanism form two relatively independent mechanisms, the independent separately motor function that realizes oneself.
Wherein, said first device 1 and second device 2 are respectively said x ray generator and said X ray receiver, perhaps are respectively said X ray receiver and said x ray generator, and promptly the position of x ray generator and X ray receiver can exchange.
More than digital drug-detecting machine provided by the present invention has been carried out detailed introduction; Used concrete example among this paper principle of the present invention and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present invention and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present invention, the part that on embodiment and range of application, all can change, in sum, this description should not be construed as limitation of the present invention.
