[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The present invention encapsulates nuclear waste rods by setting a top plate, an intermediate plate, and a bottom plate. The waste barrel is placed on the conveying mechanism of the bottom plate and is moved and conveyed by the conveying mechanism. When the waste barrel moves to the position of the grasping and lifting mechanism at the edge of the bottom plate, the movement stops. The waste barrel is grasped and lifted by the grasping and lifting mechanism, driven to rise, and cooperates with the nuclear waste rod suspended on the top plate, so that the nuclear waste rod and the waste barrel are matched. A hanging and grasping mechanism is arranged on the lower side of the top plate to grasp the nuclear waste rod. After being grasped, the nuclear waste rod moves along the guide groove of the guide rail frame. The guide rail frame is set at a right angle and is smoothly set at the right angle position. After the nuclear waste rod and the waste barrel are matched, the hanging and grasping mechanism drives the nuclear waste rod and the waste barrel to move synchronously to the right and enter the receiving box on the intermediate plate. The hanging and grasping mechanism adsorbs and grasps the nuclear waste rod through the adsorption block at the bottom, and drives it to move after adsorption. In order to achieve the locking cooperation between the nuclear waste rod and the waste barrel and subsequent synchronous movement, a sealing block is arranged on the adsorption block. Combining with the locking component arranged in the sealing block, the locking component cooperates with the locking hole arranged at the inner edge of the waste barrel to realize the sealing after the nuclear waste rod and the waste barrel are matched, and at the same time facilitate the overall movement. Combining the connecting internal thread and the connecting external thread, the lifting and rotating motor is used to control the cooperation between the rotating driving frame and the cooperation hole on the sealing cover, driving the threaded sealing connection between the sealing cover and the waste barrel, and the sealing cover is sleeved with the lifting column. A locking column is arranged in the closing block. Under the action of the return spring, the locking column retracts inside the closing block. When the closing block and the waste barrel are matched, the locking column is attracted by the magnet ring arranged at the locking hole position of the waste barrel and extends out, cooperating with the locking hole, so as to complete the locking between the closing block and the waste barrel. Subsequently, the waste barrel can be driven to move synchronously under the action of the hanging and grasping mechanism. The grasping and lifting mechanism uses the extension frame, the U-shaped frame, and the lifting threaded column for lifting operation. The side plate is used to install the cooperation frame, and the telescopic lifting frame is further installed. After the telescopic lifting frame cooperates with the lifting slot at the bottom of the waste barrel, the waste barrel is lifted. The symmetrically arranged arc-shaped clamping blocks are used, and the air pump, the pneumatic chute, and the pneumatic slider are combined to drive the arc-shaped clamping blocks to clamp the waste barrel, playing a role in stabilizing the waste barrel. During the movement of the waste barrel, through the guiding action of the guiding belt, the position deviation of the waste barrel is avoided. Through the above structure, the encapsulation and transportation operations of the nuclear waste rod and the waste barrel are realized, and the level and efficiency of automatic encapsulation are improved.

[0034] More specifically, a suspension and grasping mechanism is provided on the lower side of the top plate 1 to grasp the nuclear waste rod 3. After being grasped, the nuclear waste rod 3 moves along the guide groove 02 of the guide rail frame 01. The guide rail frame 01 is set at a right angle and is smoothly rounded at the right angle position. After the nuclear waste rod 3 and the waste barrel 5 are matched, the suspension and grasping mechanism drives the nuclear waste rod 3 and the waste barrel 5 to move synchronously to the right and enter the receiving box 10 on the intermediate plate 4.

[0035] As a further embodiment of the present invention, the suspension and grasping mechanism includes a lifting and rotating motor 03 arranged on the guide groove 02. The lifting and rotating motor 03 is connected to a lifting column 04. An adsorption block 05 is arranged at the end of the lifting column 04.

[0036] Specifically, the suspension and grasping mechanism adsorbs and grasps the nuclear waste rod 3 through the adsorption block 05 at the bottom, and drives it to move after adsorption. In order to achieve the locking cooperation between the nuclear waste rod 3 and the waste barrel 5 and subsequent synchronous movement, a sealing block is arranged on the adsorption block 05. Combining with the locking component arranged inside the sealing block, the locking component cooperates with the locking holes 52 arranged on the inner edge of the waste barrel 5 to realize the sealing after the nuclear waste rod 3 and the waste barrel 5 are matched, and at the same time facilitate the overall movement.

A magnet ring 51 is arranged at the position of the locking hole 52 of the waste bin 5. The locking post 24 is made of iron.

[0041] Specifically, the locking post 24 is arranged in the closing block 21. Under the action of the return spring 25, the locking post 24 retracts inside the closing block 21. After the closing block 21 and the waste bin 5 are fitted together, the magnet ring 51 arranged at the position of the locking hole 52 of the waste bin 5 attracts the locking post 24 to extend out and cooperate with the locking hole 52, thereby completing the locking between the closing block 21 and the waste bin 5. Subsequently, the waste bin 5 can be driven to move synchronously under the action of the hanging and grasping mechanism.

[0045] Specifically, the symmetrically arranged arc-shaped clamping blocks 69 are used, combined with the air pump 7, the pneumatic sliding groove 68, and the pneumatic slider to drive the arc-shaped clamping blocks 69 to clamp the waste bin 5, playing a role in stabilizing the waste bin 5.

[0047] Specifically, during the movement of the waste bin 5, the guiding effect of the guiding belt 8 is used to prevent the waste bin 5 from shifting in position.

[0048] The working principle of the embodiment of the present invention is:

[0049] As Figures 1-7As shown, by setting the top plate 1, the middle plate 4, and the bottom plate 11, the encapsulation operation of the nuclear waste rod 3 is carried out. The waste barrel 5 is placed on the conveying mechanism of the bottom plate 11 and is moved and conveyed by the conveying mechanism. When the waste barrel 5 moves to the position of the grasping and lifting mechanism 6 at the edge of the bottom plate 11, the movement stops. The waste barrel 5 is grasped and lifted by the grasping and lifting mechanism 6, driving the waste barrel 5 to rise, and cooperating with the nuclear waste rod 3 suspended on the top plate 1, so that the nuclear waste rod 3 and the waste barrel 5 are matched. A suspension grasping mechanism is arranged on the lower side of the top plate 1 to grasp the nuclear waste rod 3. After being grasped, the nuclear waste rod 3 moves along the guide groove 02 of the guide rail frame 01. The guide rail frame 01 is set at a right angle and is smoothly set at the right angle position. After the nuclear waste rod 3 and the waste barrel 5 are matched, the suspension grasping mechanism drives the nuclear waste rod 3 and the waste barrel 5 to move synchronously to the right and enter the receiving box 10 on the middle plate 4. The suspension grasping mechanism adsorbs and grasps the nuclear waste rod 3 through the adsorption block 05 at the bottom, and drives it to move after adsorption. In order to achieve the locking cooperation between the nuclear waste rod 3 and the waste barrel 5 and subsequent synchronous movement, a sealing block is arranged on the adsorption block 05. Combining with the locking component arranged in the sealing block, the locking component is used to cooperate with the locking hole 52 arranged at the inner edge of the waste barrel 5 to realize the sealing after the nuclear waste rod 3 and the waste barrel 5 are matched, and at the same time facilitate the overall movement. Combining the connecting internal thread 20 and the connecting external thread 50, the lifting and rotating motor 03 is used to control the cooperation between the rotating driving frame 22 and the cooperation hole 23 on the sealing cover 2, driving the threaded sealing connection between the sealing cover 2 and the waste barrel 5. The sealing cover 2 is sleeved with the lifting column 04. A locking column 24 is arranged in the closing block 21. Under the action of the return spring 25, the locking column 24 retracts inside the closing block 21. When the closing block 21 and the waste barrel 5 are matched, the magnet ring 51 arranged at the locking hole 52 position of the waste barrel 5 attracts the locking column 24 to extend and cooperate with the locking hole 52, thus completing the locking between the closing block 21 and the waste barrel 5. Subsequently, the waste barrel 5 can be driven to move synchronously under the action of the suspension grasping mechanism. The grasping and lifting mechanism 6 uses the extension frame 60, the U-shaped frame 67, and the lifting threaded column 61 to perform the lifting operation. The side plate 63 is used to install the cooperation frame 610, and further install the telescopic lifting support frame 611. After the telescopic lifting support frame 611 cooperates with the lifting slot 53 at the bottom of the waste barrel 5, the waste barrel 5 is lifted. Using the symmetrically arranged arc-shaped clamping blocks 69, combined with the air pump 7, the pneumatic chute 68, and the pneumatic slider, the arc-shaped clamping blocks 69 are driven to clamp the waste barrel 5, playing a role in stabilizing the waste barrel 5. During the movement of the waste barrel 5, through the guiding action of the guiding belt 8, the position deviation of the waste barrel 5 is avoided.
