Five baffles 65 form rectangular recess.Third baffle 63 and fourth gear plate 64 are fixed in rack 1, and all baffles are respectively positioned on CT and turn
Between disk 2 and rack 1, to form a flat box-like space by means of rack 1 and CT turntable 2.Second drag chain connector 42
It is fixed on one end on fifth gear plate 65 close to second baffle 62, the first drag chain connector 41 is located at CT rotary shaft in the initial state
Close to the side of second baffle 62 on 3, turn so that cable drag chain 4 is wound in CT with cable 5 with the posture of similar " Z " font
On disk 3 and it is placed in above-mentioned box-like space.Since first baffle 61, second baffle 62 are formed as " V " character form structure, cable is dragged
Chain 4 and cable 5 are wrapped in CT rotary shaft 3, either clockwise around rotary shaft when CT turntable 2 and the rotation of CT rotary shaft 3
Or rotation counterclockwise can drive cable drag chain 4 to swing, when cable is dragged by CT rotary shaft 3 and the first drag chain connector 41
Chain 4 rebounds when touching baffle 61/62 in swing into v-depression, rotation and gravity further with CT rotary shaft 3
Effect it is mobile towards the relatively narrow place of groove insied width, and auto-folder is on fifth gear plate 65, finally avoiding that cable occurs
And cable drag chain winding and irregular swing the problems such as.
It will be apparent to a skilled person that first baffle 61, second baffle 62 can also use asymmetric arrangement,
For example, wherein first baffle 61 is relative to vertical direction to 10 degree of the direction inclination far from 2 center of circle of CT turntable, 62 phase of second baffle
20 degree are tilted to the direction far from 2 center of circle of CT turntable for vertical direction, at this point, two baffles 6 are still formed as " V " font knot
Structure, and the angle of the V-shaped structure is 30 degree.Preferably, first baffle 61, second baffle 62 are arranged symmetrically and the two angle
Angular range is 20 °~60 °, i.e. the angle of first baffle 61 and vertical direction is 10 °~30 °, second baffle 62 and vertical side
To angle be 10 ° to 30 °.Those skilled in the art are also to be noted that first baffle 61, the length of second baffle 62 can
With unanimously can also be inconsistent, as long as a V-type groove can be formed, details are not described herein.Meanwhile first baffle 61,
Two baffles 62 can also split according to actual needs and be set as multiple, and multiple baffles are attached at different angles, Huo Zhe
One baffle, 61 core second baffle 62 is set as the shapes such as curved slab, such as arc plate etc..
In addition, in order to save cost, third baffle 63 and fourth gear plate 64 can not also be used, and by first baffle 61
It is connect respectively with fifth gear plate 65 with second baffle 62, to surround the shape of an inverted trapezoidal.Or only with first baffle
61 and second baffle 62 surround the shape of a V-shaped.At this point, third baffle 63, fourth gear plate 64 and fifth gear plate 65 surround
Rectangular recess disappear therewith, the position of the second drag chain connector 42 also adjusts therewith.
Below with reference to Fig. 5-Figure 11 description present invention using the working principle of the CT of winding structure.Since CT turntable 2 is fixed
On CT rotary shaft 3, a synchronous pulley (not shown) is installed in CT rotary shaft 3, synchronous pulley is synchronous on motor
Belt wheel forms transmission, is driven by a motor CT rotary shaft 3 and CT turntable 2 rotates, meanwhile, CT origin sensor 81 monitors CT turntable 2
Position and by location information be sent to control equipment (not shown), by control equipment control motor operation.
As shown in figure 5, the position is the initial position or origin position using the CT of winding structure, wherein first drags
Chain joint 41 is located at the position on horizontal plane close to second baffle 62, and cable drag chain 4 and cable 5 are twined from the top of CT rotary shaft 3
Around and extend, the second drag chain connector 42 of 4 other end of cable drag chain and the first drag chain connector 41 are arranged in diagonal line substantially.This
When, after CT equipment is opened, CT turntable 2 passes through back former process and reaches origin position.
As shown in fig. 6, rotated two seconds counterclockwise after CT turntable 2 reaches origin position, to reserve enough acceleration ranges,
At this point, the first drag chain connector 41 moves to the position of vertical direction and is located at the middle position of v-depression bottom, cable drag chain 4
The length wound in CT rotary shaft 3 with cable 5 further increases, and has the cable drag chain 4 of redundant length to be drawn in rectangular recess
It rises.At this point, CT equipment completes the preparation process before accelerating.Later, CT turntable 2 is rotated along pointer, reaches origin shown in fig. 5
Accelerator is completed before position.When CT equipment reaches origin position shown in fig. 5 for the second time, scanning process is opened, control dress
It sets control x ray generator 22 and detector 25 works and acquires information.
As shown in fig. 7, CT turntable 2 continues to rotate clockwise 90 °, at this point, cable drag chain 4 is at 90 ° of positions, first
Drag chain connector 41 moves to the position of vertical direction and is located at the middle position at 3 top of CT rotary shaft, cable drag chain 4 and cable 5
The length wound in CT rotary shaft 3 shortens, and has the cable drag chain 4 of redundant length under gravity to square in rectangular recess
It is moved in connected in star.
As shown in figure 8, CT turntable 2 continues to rotate clockwise 180 °, at this point, cable drag chain is at 90 ° of positions, first
Drag chain connector 41 moves to the position on horizontal plane close to first baffle 61, and cable drag chain 4 and cable 5 twine in CT rotary shaft 3
Around length disappear substantially, cable drag chain 4 and cable 5 move out under the action of the centrifugal force and contact first baffle 61,
One baffle 61 limits the amplitude of fluctuation of cable drag chain 4 and cable 5 and applies reversed active force to it, so that cable drag chain
4 stack under the action of gravity and second baffle 62 into rectangular recess.
As shown in figure 9, CT turntable 2 continues to rotate clockwise 270 °, at this point, cable drag chain 4 is at 270 ° of positions, the
One drag chain connector 41 moves to the position of vertical direction and is located at the middle position of 3 bottom of CT rotary shaft, cable drag chain 4 and cable
5 are stacked in rectangular recess.
As shown in Figure 10, CT turntable 2 continues to rotate clockwise 360 °, and cable drag chain is in 360 ° of positions, 4 He of cable drag chain
Cable 5 is pulled up out of rectangular recess, and CT scan process is completed.In order to guarantee to acquire full 360 degree of data during CT scan,
CT corner in scanning process is set and is slightly larger than 360 degree, it is usually preferred to rotate clockwise 361 degree.
As shown in figure 11, CT turntable 2 needs to continue to rotate and reduce speed now after completing scanning, when operation to 450 ° of position
When, CT turntable 2 complete to slow down and it is opposite stop, and wait the arrival of reset command with start to carry out counter motion and reset with
Next scanning is carried out, the motion process of cable drag chain 4 repeats no more.
Due to CT turntable from -90 ° to 0 ° during complete to accelerate, 0 ° to 360 ° of process is scanned, and 360 ° are arrived
Slow down during 450 °, in order to guarantee the enough accelerating spaces of CT turntable and search space, needs cable drag chain 4 and cable 5
Length can satisfy CT turntable from -90 ° rotation to 450 °.Because of the limited length of drag chain, CT turntable can only be in limited angle
Interior rotation, beyond limitation range, it will the effect of pullling is generated to cable drag chain and cable, its service life is damaged or even safe thing occurs
Therefore.In addition, extreme position, which quick and precisely finds origin position for CT disk, essential work when CT hang-up
With.Therefore, in an embodiment of the present invention, the effective angle range of CT is -90 °~450 °, well beyond the range of a circle.
Above-described, only presently preferred embodiments of the present invention, the range being not intended to limit the invention, of the invention is upper
Stating embodiment can also make a variety of changes.Made by i.e. all claims applied according to the present invention and description
Simply, equivalent changes and modifications fall within the claims of the invention patent.The not detailed description of the present invention is
Routine techniques content.
