Embodiment
Below in conjunction with drawings and Examples, the technical scheme in the present invention is clearly and completely described.
As shown in Figure 1 and Figure 2, the present embodiment provides a kind of pail for used dressings surface dose rate pick-up unit, comprises rotating mechanism, side detector motion mechanism, top detector motion and corresponding failure reset device thereof and support.
Described rotating mechanism is divided into motor 5, reducer casing 4, pivoting support 1 and support 2, and wherein motor 5 and reducer casing 4 form drive unit, and pivoting support 1 is the core component of turntable, both gears meshing; Be fixed on detector 3 on support for measuring dose rate level bottom pail for used dressings, pivoting support 1 is provided with guide plate 7 and register pin 6; Pail for used dressings puts into the process of turntable from top to bottom, after being first directed to plate 7 Primary Location, continuing accurately to be located by 3 register pins 6 when declining again, ensure that pail for used dressings is accurately put in turntable central authorities.
Side detector motion mechanism is divided into motor 16, screw mandrel and guide rail 18, sliding plate 19 and support 20; Sliding plate 19 is fixed with for measuring pail for used dressings side dose rate level detector 3, sliding plate 19 is arranged on guide rail and is connected with motor by screw mandrel, to realize the movable object of detector.The failure reset device of this motion is made up of rotating shaft 8 and spring 17, and described guide rail is fixed on support, and support one end is set in rotating shaft 8, and the support other end is connected with spring 17; At mechanism malfunction, when detector cannot be regained, detector can 8 swing around the shaft, occurs firmly to contact, damage detection device when lifting by crane to prevent pail for used dressings with detector; Spring 17 is in order to when ensureing normally to use, detector is positioned at correct position.
The spring that top detector motion is divided into motor 12, reducer casing 10, pivoted arm 11, electromagnetic clutch 9, steel wire 13, pulley 14 and is placed in spring protecting jacket 15.Described pivoted arm 11 is fixed with the detector 3 for measuring pail for used dressings top dose rate level, pivoted arm 11 is connected with motor 12 by electromagnetic clutch 9, reducer casing 10, and pivoted arm 11 is connected with back-moving spring by steel wire 13, pulley 14 simultaneously.Under normal circumstances, detector 3 drives it to swing up and down with pivoted arm 11 by motor, and spring is stretched; When there is mechanical fault, by electromagnetic clutch 9 power-off, spring pulls pivoted arm 11 to rotate by steel wire 13, makes detector away from pail for used dressings, thus does not affect hanging away of pail for used dressings.
Be illustrated in figure 3 the schematic diagram of this pail for used dressings surface dose rate pick-up unit use-case, in this schematic diagram, pail for used dressings 21 is in working position, and pail for used dressings surface dose rate level measured by each detector.Its workflow is as follows: pail for used dressings from top to bottom lifts to be put into turntable → side detector motion mechanism and drive detector to move to working position by rest position, it is made to drive detector to turn to working position by rest position near pail for used dressings side surface → top detector motion, make it after pail for used dressings top surface → start measurement → measuring process terminates, top detector motion drives detector to turn to rest position by working position, it is made to drive detector to move to rest position by working position away from pail for used dressings top surface → side detector motion mechanism, it is made to be hung away → end-of-job away from pail for used dressings side surface → pail for used dressings.
The content be not described in detail in this instructions, belongs to the known prior art of those skilled in the art.
