Please emphasis consult shown in Figure 5ly, described CT machine slicing device 1 also comprises the prompting apparatus 17 that resets of being located on the second bracing or strutting arrangement 11, is used for the first section 120 and second cut into slices 121 carrying out initial zero-bit deal with return to zero.The described prompting apparatus 17 that resets comprises by bolt and is installed in the photoswitch 170 on the second side plate 113 of the second bracing or strutting arrangement 11 and is bolted on photoelectricity contact 171 on the second contiguous block 1421 of the second nut seat 142.Described photoelectricity contact 171 can be mobile with the second nut seat 142.Described photoswitch 170 is positioned on the motion track of described photoelectricity contact 171, can when being close to, the first section the 120 and second section 121 cut off the signal of photoswitch 170, and make photoswitch 170 be in closure state, and then the first section the 120 and second section 121 has been got back to the signal feedback of initial zero-bit to electric machine control system.It is that spacing is zero between the first section the 120 and second section 121 that described the first section the 120 and second section 121 is close to, and is in closure state between two sections, can stop the X ray from x-ray source fully.
When drive motors 13 makes the rotating shaft 130 of motor 13 rotate along first direction, the double nut leading screw 140 of actuating device 14 can be around axial-rotation under the drive of the rotating shaft 130 of motor 13, the first nut seat 141 with the cooperation of the first screw thread 1402 under do axially-movable, the second nut seat 142 with the cooperation of the second screw thread 1403 under do axially-movable.Because the first screw thread 1402 is opposite with the rotation direction of the second screw thread 1403, thus described the first nut seat 141 and the second nut seat 142 along the axial direction work of double nut leading screw 140 in opposite directions or from moving.As, when the rotating shaft 130 of motor 13 was rotated along first direction, the first nut seat 141 occured from moving along double nut leading screw 140 axial directions with the second nut seat 142.The second fixed part 12011 of the second end 1201 of cause the first section 120 is fixedly arranged on the first nut seat 141 by the first contiguous block 1411, the first fixed part 12010 of the second end 1201 of the first section 120 is bolted on the 3rd guide runner 116, therefore, when the first nut seat 141 when moving axially along double nut leading screw 140, the second end 1201 that is fixed on first on the 3rd guide runner 116 section 120 can move along the second guide rail 115 under the effect of the 3rd guide runner 116, and the first end 1200 that drives the first section 120 moves along the first guide rail 105 under the effect of the first guide runner 106.
In like manner, when the second nut seat 142 when moving axially along double nut leading screw 140, the second end 1211 that is fixed on second on the 4th guide runner 117 section 121 can move along the second guide rail 115 under the effect of the 4th guide runner 117, and the first end 1210 that drives the second section 121 moves along the first guide rail 105 under the effect of the second guide runner 107.Because the first nut seat 141 and the second nut seat 142 are to do from moving along the axial direction of double nut leading screw 140, and the first section the 120 and second section 121 is to move under the drive of the first nut seat 141, the second nut seat 142 respectively, so, described the first section 120 and the second section 121 are done from moving along the first guide rail 105, the second guide rail 115, until the first section 120 and second is cut into slices distance between 121 reach clinical scanning need to spacing till.
When needs dwindle the first section 120 and second and cut into slices spacing between 121, but drive motors 13 makes the rotating shaft 130 of motor 13 rotate along second direction.At this moment, double nut leading screw 140 rotates along second direction under the drive of the rotating shaft 130 of motor 13.The first nut seat 141 can cooperate with the first screw thread 1402 of double nut leading screw 140 and 141 generations of the first nut seat are moved axially.The second nut seat 142 can cooperate with the second screw thread 1403 of double nut leading screw 140 and the generation of the second nut seat is moved axially.The first nut seat 141 and the second nut seat 142 produce move toward one another.The first section the 120, second section 121 issues looks to motion in the drive of the first nut seat 141, the second nut seat 142 respectively, and then reduces the spacing between the first section the 120 and second section 121, until reach the clinical scanning demand.
CT machine of the present utility model rotates by the double nut leading screw 140 that drive motors 13 drives actuating device 14 with slicing device 1, and the first screw thread 1402 by double nut leading screw 140 cooperates with the first nut seat 141 and the second screw thread 1403 with make cooperating of the second nut seat 142 the first nut seat 141 and the second nut seat 142 occur in opposite directions with from motion, and then make in the screw thread scope of the first section the 120 and second section 121 at two threaded screw rods 140 generation under the drive of the first nut seat 141 and the second nut seat 142 in opposite directions or from motion, with the spacing between any adjustment two sections, can satisfy the demand of clinical scanning, and improve the positioning accuracy between two sections.In addition, the adjustment that cooperates spacing between the realization section by the first opposite screw thread 1402 of double nut leading screw 140 rotation directions, the second screw thread 1403 and the first nut seat 141, the second nut seat 142, simple in structure, easy to operate, and can not occur causing adjusting spacing between the section because fatigue failure appears in life-time service.
It should be noted that, in above-described embodiment, the nut screw of described actuating device is provided with two sections screw threads, and corresponding described actuating device has comprised two nut seats (141 and 142) corresponding with described two sections screw threads (1402 and 1403), and in the implementation, can be provided with multistage (more than or equal to 3) screw thread on the described nut screw (140), described actuating device comprises a plurality of nut seats that are complementary with described multistage screw thread accordingly, and the rotation direction of two sections adjacent screw threads is opposite in the described multistage screw thread.Fix the corresponding section of described section assembly on the described nut seat, thereby when electric machine rotation, drive section on the adjacent nut seat and do from or move in opposite directions.
Although this utility model with preferred embodiment openly as above; but it is not to limit this utility model; any those skilled in the art are not within breaking away from spirit and scope of the present utility model; can make possible change and modification, therefore protection domain of the present utility model should be as the criterion with the scope that this utility model claim is defined.
