Still further, a transition plate 11 is arranged between the main conveyor belt 1 and the three small conveyor belts 5, the transition plate 11 is arranged on the ground through a support rod 92, and bearing planes of the transition plate 11, the main conveyor belt 1 and the three small conveyor belts 5 are on the same horizontal plane, so that a gap between the main conveyor belt 1 and the small conveyor belts 5 can be transited through the transition plate 11, and the phenomenon that the nuclear waste packaging bodies 6 fall into the gap between the main conveyor belt 1 and the small conveyor belts 5 when reaching the main conveyor belt 1 from the small conveyor belts 5 to cause toppling is avoided.
Still further, a protruding part 50 surrounding the belt body of the conveyor belt is arranged on the belt body of the small conveyor belt 5, so that the distance between the bearing plane of the small conveyor belt 5 and the ground is greater than the distance between the top surfaces of the fixed frames 51 at the two sides of the small conveyor belt 5 and the ground.
Further, a receiving device 9 is arranged on the ground at the tail end of the main conveyor belt 1 in the advancing direction, the receiving device 9 comprises a receiving plate 90 and a supporting rod 92, one end of the supporting rod 92 is installed on the ground, the other end of the supporting rod 92 is installed on the receiving plate 90, the bearing plane of the receiving plate 90 and the bearing plane of the main conveyor belt 1 are in the same horizontal plane, two rows of grooves 91 penetrating through the receiving plate 90 are arranged on the receiving plate 90, and therefore the conveying part of the forklift can penetrate through the two rows of grooves 91 to lift the nuclear waste packaging bodies 6 on the receiving plate 90 and then convey the nuclear waste packaging bodies away from the receiving plate 90.
Furthermore, two parallel runway-type tracks 7 are arranged on one surface, close to the conveyor belt, of the cover plate 3 along the advancing direction of the conveyor belt, a plurality of pairs of thrusters 8 capable of moving around the runway-type tracks 7 are arranged on the two runway-type tracks 7, the two thrusters 8 of each pair are respectively positioned on the two runway-type tracks 7, and when each pair of thrusters 8 move on the runway-type tracks 7 along the advancing direction of the main conveyor belt 1, each pair of thrusters 8 can move in opposite directions, so that the nuclear waste packaging bodies 6 on the main conveyor belt 1 are clamped.
Referring to fig. 4 to 6, the pushing device 8 includes a roller 86 mounted on the runway track 7, the roller 86 is driven by a transmission shaft 85, a sprocket 10 and a bearing 87 are mounted on the transmission shaft 85, an inner ring of the bearing 87 is mounted on the transmission shaft 85, an outer ring of the bearing 87 is mounted with a vertically downward connecting rod 80, a mounting plate 83 parallel to the ground horizontal plane is mounted on the connecting rod 80, a driving device C52 for driving the transmission shaft 85 to rotate is mounted on the mounting plate 83, a sprocket 10 is mounted on a rotor of the driving device C52, and the transmission shaft 85 and the sprocket 10 on the rotor of the driving device C52 are connected by a chain, so that the driving of the transmission shaft 85 is realized, and the roller 86 is driven to move on the runway track 7; and a pushing cylinder or electric push rod 82 is arranged on the mounting plate 83, a push plate 84 is arranged on the rod head of the pushing cylinder or electric push rod 82, and when the pushing devices 8 and the main conveyor belt 1 move in the same direction, two pushing cylinders or two electric push rods in each pair of pushing devices 8 move oppositely. Therefore, the nuclear waste packaging body 6 is clamped through the two pushing oil cylinders or the electric push rod 82, and the phenomenon that the nuclear waste packaging body 6 is toppled is avoided. Because the size of each nuclear waste packaging body 6 differs, some nuclear waste packaging bodies 6 are likely to be higher, and the contact area with the conveyor belt is smaller, and if jolt occurs on the conveyor belt, the nuclear waste packaging bodies 6 are easy to topple.
Furthermore, the connecting rod is an electric telescopic rod. Because some nuclear waste packing bodies 6 may have the problems of too low height and small contact surface with the conveyor belt, the height of the mounting plate 83 needs to be adjusted through an electric telescopic rod, so that the height of the pushing oil cylinder or the electric push rod 82 is adjusted, and the clamping effect on the nuclear waste packing bodies 6 is realized.
Referring to fig. 7, the driving device B81 of the three small conveyor belts 5 is driven by the same servo motor, the rotor of the servo motor is meshed with the gear 53 on the rotating shaft 54 through the gear 53, so as to drive the rotating shaft 54 to rotate, three chain wheels 10 are mounted on the rotating shaft 54, and correspond to the chain wheels 10 on the three small conveyor belts 5 respectively, and the chain wheels 10 are connected through chains, so as to realize the synchronous motion of the three conveyor belts.
Referring to fig. 8, most of the fixing frames 51 on both sides of the conveyer belt on the market are slightly higher than the bearing plane of the conveyer belt, and if the conveyer belt is used, the nuclear waste packages 6 will contact the fixing frames 51 on both sides of the small conveyer belt 5 after the fork truck carries the nuclear waste packages 6 onto the small conveyer belt 5, so that the nuclear waste packages 6 cannot be transported onto the main conveyer belt 1, and therefore, it is necessary to provide a protrusion 50 for the conveyer belt to prevent the fixing frames 51 on both sides of the small conveyer belt 5 from contacting. However, some of the belts in the market have a carrying plane higher than the two side fixing frames 51, and the protruding portions 50 are not required for the belts, and the present invention can also be designed with reference to the belts.
The present invention is described in detail by the following steps:
And 2, operating pushing devices 8 arranged on the two runway type tracks 7 above the small conveyor belt 5, and pushing an oil cylinder or an electric push rod 82 to move so that a push plate 84 is tightly attached to the nuclear waste packaging body 6.
And 3, simultaneously starting the driving device B81 and the driving device C52, so that the pushing device 8 and the small conveyor belt 5 move synchronously.
And 5, the nuclear waste package bodies 6 follow the movement of the small conveyor belts 5 until the small conveyor belts 5 are completely separated from each other, then the small conveyor belts 5 stop running, and the nuclear waste package bodies 6 move to the main conveyor belt 1 which moves synchronously with the small conveyor belts 5 through the transition plates 11.
And 6, when the nuclear waste package 6 passes through the detection area of the plastic scintillator detector 4, detecting nuclides inside the nuclear waste package 6 through the plastic scintillator detector 4, and when the nuclear waste package 6 leaves the detection area of the plastic scintillator detector 4 along with the main conveyor belt 1, completing the detection of the nuclear waste package 6.
And 7, the nuclear waste package body 6 moves to the tail end of the main conveyor belt 1 along with the main conveyor belt 1, moves to the receiving plate 90, retracts by the pushing oil cylinder or the electric push rod 82, moves to one end of the small conveyor belt 5, and moves the nuclear waste package body 6 away from the receiving plate 90 through a forklift, so that the detection of the nuclear waste package body 6 is completed.
It should be noted that, in the invention, the main conveyor belt 1 starts to operate when or before the first nuclear waste package 6 is placed on the small conveyor belt 5, so that when the nuclear waste package 6 on the small conveyor belt 5 completely leaves the small conveyor belt 5, and the small conveyor belt 5 stops operating, the nuclear waste package 6 can be continuously conveyed to the small conveyor belt 5 by the forklift, and then the nuclear waste package 6 is clamped by the thrusters 8 mounted on the two runway type rails 7, because the pairs of thrusters 8 are arranged on the two runway type rails 7 of the invention, the nuclear waste package returns to the small conveyor belt 5 after going around the runway type rails 7 for one circle.
