[0052] Among them, the door-type frame 11 includes a pair of support columns 1101 and a horizontal beam 1102 horizontally connected between the pair of support columns 1101. Any support column 1101 is thicker at the bottom and thinner at the top, and has stable support. The pair of support columns 1101 and the third mounting plate 10 are connected by flanges.

[0057] Among them, the fifth driving device includes a driving box 23 slidingly connected between a pair of T-shaped columns 19 and four groups of first connecting seats 24 installed equidistantly along the sealing cover 16. A grab arm assembly is rotatably connected between any first connecting seat 24 and the sealing cover 16.

[0058] For details, please refer to Figure 1 and Figure 3The first driving device also includes a first motor 25 fixedly mounted on the first mounting plate 7, a first motor wheel 26 is coaxially mounted on the output end of the first motor 25, and a second motor wheel 27 is coaxially mounted on the connecting shaft 4 close to the side of the first mounting plate 7. The first motor wheel 26 and the second motor wheel 27 are connected by a motor chain transmission. By starting the first motor 25, the output end of the first motor 25 drives the coaxial first motor wheel 26 to rotate. Since the first motor wheel 26 and the second motor wheel 27 are connected by a motor chain transmission, the rotating second motor wheel 27 drives the roller 5 forward or backward.

[0059] For details, please refer to Figure 1 and Figure 4 The second driving device also includes a first gear 28 rotatably connected to the second mounting plate 8 via a bearing. A second motor 29 is fixedly mounted in the second mounting frame 2. A second gear 30 is coaxially mounted on the output end of the second motor 29. The first gear 28 is meshed with the second gear 30. By starting the second motor 29, the output end of the second motor 29 drives the coaxial second gear 30 to rotate. Since the first gear 28 is meshed with the second gear 30 and the first gear 28 is fixedly mounted on the third mounting frame 9, the third mounting frame 9 is driven to rotate. This facilitates the real-time adjustment of the rotation of the device according to the location of the radioactive waste during movement.

[0060] For details, please refer to Figure 1 and Figure 5 The threaded screw rod 14 is threadedly connected to the nut seat 31, one end of the threaded screw rod 14 passes through the shaft seat, and the end of the threaded screw rod 14 passing through is connected to the third motor 50 through a coupling. By starting the third motor 50, the output end of the third motor 50 drives the threaded screw rod 14 to rotate through the coupling, providing power output for the linear motion of the nut seat 31;

[0061] Limit blocks 32 are installed at both ends of the pair of slide rails 13 , and rubber pads 33 are installed on the opposite surfaces of the limit blocks 32 at both ends. The rubber pads 33 play a role in limiting and buffering the movement of the base 35 .

[0062] Specifically, please refer to the figure. A hanging ring 1501 is installed on the outer wall of the sealed barrel 15. The sealed barrel 15 is provided with a shielding support layer, a fast neutron moderation layer, and a gamma ray absorption layer from the outside to the inside. The shielding support layer is a stainless steel plate, which can scatter some fast neutrons and reduce the impact of fast neutrons on electronic equipment. The fast neutron moderation layer is a boron-containing polyethylene plate, which has a good neutron moderation effect and a low density. The gamma ray layer is a lead plate, which can absorb gamma rays generated by the interaction of neutrons with the first two layers of materials to reduce the amount of gamma rays entering.

[0063] Specifically, referring to the figure, the base assembly includes a slider 34 slidably connected to a pair of slide rails 13. A base 35 is mounted between the upper surfaces of the pair of sliders 34. The base 35 is mounted together with the nut seat 31. The pair of sliders 34 constrain the rotation of the nut seat 31, thereby changing the original rotation work of the threaded screw 14 driven by the third motor 50 into a linear work of moving the nut seat 31, thereby driving the sealing barrel 15 to switch between different working positions.

[0064] Four sets of positioning devices are installed on the upper surface of the base 35 , and the four sets of positioning devices are respectively located at the four corners of the upper surface of the base 35 .

[0065] For details, please refer to Figure 1 and Figure 7 Any positioning device includes a positioning column 36 vertically mounted on the base 35 and a positioning platform 37 installed along the circumference of the sealing barrel 15. The upper end of the positioning column 36 is rotatably connected to a knob 38 through a bearing. The knob 38 is internally threaded with an adjusting screw 39. A pulley seat 40 is installed on the side of the adjusting screw 39 close to the sealing barrel 15. A rubber wheel 41 is rotatably connected to the pulley seat 40 through a pin. The rubber wheel 41 is against the outer wall of the sealing barrel 15. When the sealing barrel 15 moves on a pair of slide rails 13, the rubber wheel 41 is against the outer wall of the sealing barrel 15, which limits the shaking of the sealing barrel 15. After the sealing barrel 15 performs the capping operation, it can be quickly rolled out in cooperation with the rubber wheel 41 under the action of the tension of the chain 22.

[0066] For details, please refer to Figure 1 The fourth driving device also includes an L-shaped mounting plate 42 fixed on the horizontal beam 1102. The L-shaped mounting plate 42 is located on one side of the U-shaped seat 20. A fourth motor 43 is installed on the L-shaped mounting plate 42. The output end of the fourth motor 43 is connected to the main shaft 44 through a coupling. The end of the main shaft 44 away from the fourth motor 43 coaxially passes through the sprocket 21 in the U-shaped seat 20. By starting the fourth motor 43, the output end of the fourth motor 43 drives the main shaft 44 to rotate, and the rotating main shaft 44 drives the coaxial sprocket 21 to rotate. The rotating sprocket 21 controls the retraction and extension of the chain 22 by the rotation direction, thereby controlling the descent and ascent of the sealing cover 16.

[0067] For details, please refer to Figure 1 and Figure 6The driving box 23 includes an upper slide 2301 and a lower slide 2302 slidably installed between a pair of T-shaped columns 19. A cylinder can be installed between the upper slide 2301 and the horizontal beam 1102 to push the movement of the upper slide 2301. It can also be manually operated. A tension spring is installed between the lower slide 2302 and the limit plate 45. A guide rail sleeve 2303 is installed between the upper slide 2301 and the lower slide 2302. A column 2304 is slidably connected in the lower slide 2302. A sliding claw 2307 is installed on the outer wall of the upper end of the column 2304. The sliding claw 2307 is slidably connected in the guide rail sleeve 2303. A push rod 2305 is installed on the lower surface of the column 2304. A hook 2306 that matches the strip slot 4501 is installed at the lower end of 2305. In the initial stage, the hook 2306 is hung in the strip slot 4501 on the limit plate 45. When the upper slide plate 2301 is pressed, the sliding claw 2307 slides on the guide rail sleeve 2303 along the trajectory of the guide rail sleeve 2303 to the critical point. At the same time, the sliding claw 2307 drives the column 2304 to rotate when sliding, so that the hook 2306 that was originally perpendicular to the strip slot 4501 rotates ninety degrees and is horizontal to the strip slot 4501. Under the action of the tension spring, the drive box 23 is driven to move upward as a whole, and the hook 2306 is separated from the limit plate 45, providing power for the grab arm assembly to hook the hanging ring 1501.

[0068] For details, please refer to Figure 1 and Figure 6 Each grab arm assembly includes a second connecting seat 46 mounted on the upper slide 2301. A first engaging arm 47 is rotatably connected to the second connecting seat 46. The end of the first engaging arm 47, which is remote from the second connecting seat 46, is rotatably connected to a second engaging arm 48 via a pin. The second engaging arm 48 is rotatably connected to the first connecting seat 24. A hanging arm 49 is mounted on the second engaging arm 48, which is compatible with the hanging ring 1501. When the drive box 23 moves upward as a whole, it drives the first engaging arm 47 upward, thereby driving the second engaging arm 48 to rotate about the first connecting seat 24 to hook the hanging ring 1501, thereby tightly clamping the sealing cover 16 to the sealing barrel 15.

[0069] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation mode of the present invention in actual process is described in detail below.

[0070] In actual application, radioactive waste is placed in the sealing barrel 15, and the third motor 50 is started. The output end of the third motor 50 drives the threaded screw 14 to rotate through the coupling, and the pair of sliders 34 set up constrains the rotation degree of the nut seat 31, thereby changing the original rotation work of the threaded screw 14 driven by the third motor 50 into a linear work of moving the nut seat 31, thereby driving the sealing barrel 15 to move below the sealing cover 16, and starting the fourth motor 43. The output end of the fourth motor 43 drives the main shaft 44 to rotate, and the rotating main shaft 44 drives the coaxial sprocket 21 to rotate. The rotating sprocket 21 controls the retraction and extension of the chain 22 by the rotation direction, thereby controlling the descent and ascent of the sealing cover 16. The descending sealing cover 16 is located below the sealing cover 16. On the sealing barrel 15, the upper slide plate 2301 is pressed, and the sliding claw 2307 slides on the guide rail sleeve 2303 along the track of the guide rail sleeve 2303 to the critical point. At the same time, the sliding claw 2307 drives the column 2304 to rotate when sliding, so that the hook 2306, which was originally perpendicular to the strip notch 4501, rotates 90 degrees and is horizontal with the strip notch 4501. Under the action of the tension spring, the driving box 23 is driven to move upward as a whole, and the hook 2306 is separated from the limit plate 45. When the driving box 23 moves upward as a whole, it drives the first connecting arm 47 to move upward, thereby driving the second connecting arm 48 to rotate with the first connecting seat 24 as the fulcrum to hook the hanging ring 1501, and the sealing cover 16 tightly covers the sealing barrel 15. Finally, it is moved to the burial point by the transport vehicle.

[0071] By pressing the upper slide plate 2301 again, the sliding claw 2307 slides on the guide rail sleeve 2303 along the trajectory of the guide rail sleeve 2303 to the critical point. At the same time, the sliding claw 2307 drives the column 2304 to rotate when sliding, so that the hook 2306 is hung in the strip groove 4501. When the drive box 23 descends as a whole, it drives the first connecting arm 47 to descend, thereby driving the second connecting arm 48 to rotate with the first connecting seat 24 as the fulcrum to disengage from the hanging ring 1501, so that the sealing barrel 15 is separated from the sealing cover 16.

[0072] The above specific embodiments will allow those skilled in the art to easily implement the present invention. However, it should be understood that the present invention is not limited to the above specific embodiments. Based on the disclosed embodiments, those skilled in the art can arbitrarily combine different technical features to implement different technical solutions.
