[0018] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. The described embodiments should not be regarded as limitations on this application. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] In the following description, reference is made to "an embodiment," which describes a subset of all possible embodiments. However, it is understood that "an embodiment" may be the same subset or a different subset of all possible embodiments and may be combined with each other without conflict.

[0020] In the following description, the terms "first" and "second" are used merely to distinguish similar objects and do not represent a specific ordering of objects. It is understood that "first" and "second" may be interchanged in a specific order or sequence where permitted, so that the embodiments of this application described herein can be implemented in an order other than that illustrated or described herein.

[0021] This application provides a cutting device 100 for cutting radioactive containers. Please refer to [link to relevant documentation]. Figures 1 to 6 The cutting device 100 includes a cutting base 1, a lifting device 2, a clamping device 3, a rotating device 4, and a cutting device 5. The cutting base 1 is disposed on a shielding facility and has a cutting opening 1a communicating with the wellhead of the shielding facility. The lifting device 2 is disposed on the cutting base 1 and is configured to drive the radioactive container segment to extend out from the cutting opening 1a. The clamping device 3 is disposed on the cutting base 1 and is used to clamp and release the radioactive container. The rotating device 4 is disposed on the cutting base 1 and is used to drive the radioactive container to rotate about its axis. The cutting device 5 is disposed on the cutting base 1 and is used to cut the extended portion of the radioactive container.

[0022] The cutting base 1 refers to a structure that is set at the shielding location and can provide a support and mounting position for the lifting device 2, clamping device 3, rotating device 4 and cutting device 5.

[0023] The cutting opening 1a can be located in the central area of ​​the cutting base 1.

[0024] The cutting device 5 refers to a device capable of cutting the protruding part.

[0025] The lifting device 2 refers to the device that can lift the radioactive container located inside the shielding facility out of the cutting opening 1a in sections for segmented cutting.

[0026] Clamping device 3 refers to a device that can clamp and release the radioactive container so that the cutting device 5 can cut it.

[0027] Rotating device 4 refers to a device that can drive the radioactive container to rotate around its axis in order to cooperate with cutting device 5 to cut it.

[0028] It should be noted that clamping here refers to holding, that is, after the clamping device 3 clamps the radioactive container, it does not mean that the radioactive container is immobile. The radioactive container can still be rotated around its axis by the drive of the rotating device 4.

[0029] For example, a radioactive container can be a cylinder or other similar object.

[0030] The axis of a radioactive container can be vertical.

[0031] For example, in one embodiment, the radioactive container may be a radioactive pressure vessel, which may be an aluminum, thin-walled 101-pile inner shell with a total length of 5 m.

[0032] The cutting device 100 provided in this application sets the cutting base 1 at the shielding facility and aligns its cutting opening 1a with the wellhead. Then, the radioactive container located in the deep well of the shielding facility is lifted out of the cutting opening 1a in sections by the lifting device 2. The protruding part is then cut by the cutting device 5. In this way, the shielding effect of the shielding facility on radioactive rays can be utilized to achieve simultaneous lifting and cutting. This not only avoids the radioactive container being exposed to the operating environment as a whole, reducing the radiation dose at the operating site, thereby reducing the risk of radiation leakage and minimizing damage to operators and the environment, but also facilitates the cutting of long and large radioactive containers. The clamping device 3 and the rotating device 4 assist the cutting device 5 in cutting the protruding part stably and quickly, thereby improving the decommissioning efficiency of the radioactive container.

[0033] For example, Figure 3 In this context, R1 can be the first direction, R2 can be the second direction, and R3 can be the axis of the radioactive container.

[0034] In one embodiment, please refer to Figure 2 and Figure 4 The lifting device 2 includes a lifting transmission assembly 21 and a lifting tray 22. The lifting transmission assembly 21 is installed on the cutting base 1, and the lifting tray 22 is used to carry the radioactive container. The lifting transmission assembly 21 is connected to the lifting tray 22 by a steel wire rope. The lifting transmission assembly 21 drives the lifting tray 22 to move within the shielding facility by winding and unwinding the steel wire rope.

[0035] For example, the lifting tray 22 can be square in shape.

[0036] The lifting transmission assembly 21 can be fixed to the cutting base 1 with fasteners.

[0037] The lifting transmission assembly 21 is connected to the lifting tray 22 via a steel wire rope. The lifting transmission assembly 21 drives the rotation to wind and unwind the steel wire rope, thereby moving the lifting tray 22, located within the shielding facility, along the axial direction of the radioactive container to lift out a set length of cutting segment each time.

[0038] Here, by using the lifting transmission assembly 21 set on the lifting tray 22 and connecting the lifting tray 22 with a steel wire rope, when it is necessary to cut the radioactive container, the radioactive container can be lifted by retracting the steel wire rope, so as to more easily achieve the segmented lifting effect, avoid the overall exposure of the radioactive container, and reduce the radiation dose of the operating environment.

[0039] In one embodiment, please refer to Figure 4 The lifting transmission assembly 21 includes a lifting motor 211, multiple lifting drive shafts 212, multiple lifting commutators 213, and multiple reels 214. The multiple lifting drive shafts 212 are arranged around the cutting opening 1a, and the lifting motor 211 is driven by any one of the lifting drive shafts 212. Adjacent lifting drive shafts 212 are connected via a lifting commutator 213. Multiple reels 214 are arranged on the cutting base 1 and are used to hold the wire rope. Each lifting drive shaft 212 is driven by at least one reel 214, and the lifting motor 211 drives the lifting drive shaft 212 to cause the reel 214 to wind up and unwind the wire rope.

[0040] The commutator 213 refers to a structure that can change the direction of transmission.

[0041] For example, the lift commutator 213 can be a right-angle commutator.

[0042] For example, the number of lifting drive shafts 212, reels 214, and lifting reversing devices 213 can all be four. The four lifting drive shafts 212 are arranged in a roughly "U" shape around the cutout 1a. Two adjacent lifting drive shafts 212 can be connected to a lifting reversing device 213 through a first coupling 216. Each lifting drive shaft 212 passes through a reel 214, and the reel 214 can be fixed to the lifting drive shaft 212 by a flat key and a flexible retaining ring, so that the lifting drive shaft 212 can drive the reel 214 to rotate, thereby winding and unwinding the wire rope inside the reel 214, so that the lifting drive assembly 21 forms a closed loop. The wire ropes in the four reels 214 can be connected to the four corners of the lifting tray 22.

[0043] For example, the lifting motor 211 can be a variable frequency speed control motor.

[0044] For example, the lifting motor 211 can be driven to any one of the lifting drive shafts 212 via the lifting reducer 217.

[0045] For example, each reel 214 is provided with two mounting bases 215, each mounting base 215 can be fixed to the cutting base 1 by four bolts.

[0046] Here, by setting up a lifting motor 211 and multiple lifting drive shafts 212, multiple reels, and multiple lifting reversing devices 213, multiple lifting drives are arranged around the cutting opening 1a, and each lifting drive shaft 212 is driven and connected to at least one reel 214, so that the multiple reels 214 are also distributed around the cutting opening 1a. The steel wire rope in each reel 214 is connected to the lifting tray 22. In this way, by driving one of the lifting drive shafts 212 through the lifting motor 211 and driving the multiple reels 214 to wind and unwind the steel wire rope through the multiple lifting reversing devices 213, the lifting tray 22 can be lifted synchronously in the circumferential direction. This not only improves the load-bearing capacity of the radioactive container, but also improves the lifting stability of the radioactive container, so as to accurately control the extension length of each section of the radioactive container, which is convenient for the cutting device 5 to cut.

[0047] In one embodiment, please refer to Figure 2 The lifting pallet 22 includes a pallet body 221 and a rotating assembly 222. The pallet body 221 is connected to a wire rope, and the rotating assembly 222 is movably disposed on the pallet body 221 for carrying the radioactive container. The rotating assembly 222 is configured to rotate with the radioactive container.

[0048] For example, the rotating assembly 222 may include a slewing bearing and a slewing motor. The radioactive container may be fixed to the slewing bearing, and the slewing bearing may be driven by the slewing motor to rotate with the radioactive container.

[0049] Thus, by setting a rotating component 222 on the disc body 221, it can rotate with the radioactive container to prevent the wire rope from getting tangled during cutting.

[0050] In one embodiment, please refer to Figure 1 and Figure 2 The cutting equipment 100 also includes a pulley assembly 6, which is disposed on the cutting base 1, and the wire rope is connected to the lifting tray 22 through the pulley assembly 6.

[0051] For example, there can be multiple pulley assemblies 6, which can be spaced circumferentially along the cut 1a, with each pulley assembly 6 cooperating with the wire rope of a reel 214.

[0052] This allows the wire rope to be guided and positioned, improving the stability of lifting the radioactive container.

[0053] In one embodiment, please refer to Figure 2 and Figure 5The clamping device 3 includes a clamping transmission assembly 31, a clamping drive motor 32, and two clamping seats 33. The two clamping seats 33 are arranged along a first direction and movably mounted on the cutting base 1. The clamping transmission assembly 31 is mounted on the cutting base 1 and is drivenly connected to the two clamping seats 33. The clamping drive motor 32 is drivenly connected to the clamping transmission assembly 31, and the clamping drive motor 32 adjusts the distance between the two clamping seats 33 along the first direction by driving the clamping transmission assembly 31 to clamp and release the radioactive container, wherein the first direction is perpendicular to the axial direction of the radioactive container.

[0054] For example, the clamping transmission assembly 31 may include a clamping screw 311 and two clamping nuts. The clamping screw 311 may extend along a first direction. The two clamping nuts have opposite threads and are sleeved on the clamping screw 311. Two clamping seats 33 are respectively installed on the two clamping nuts. The clamping drive motor 32 may be set on one side of the cutting base 1 along the first direction. The rotation axis of the clamping drive motor 32 may be parallel along a second direction. The clamping drive motor 32 may be connected to the clamping screw 311 through a connecting rod and a reversing device. By driving the clamping screw 311 to rotate forward and backward, the distance between the two clamping nuts along the first direction can be adjusted, thereby clamping and releasing the radioactive container.

[0055] Here, by driving the clamping transmission assembly 31 through the clamping drive motor 32, the distance between the two clamping seats 33 along the first direction can be adjusted, thereby clamping and releasing the radioactive container, which facilitates the cutting device 5 to perform cutting.

[0056] As an example, in one embodiment, please refer to Figure 2 and Figure 5 The clamping seat 33 has a notch 33a that fits the outer peripheral surface of the radioactive container, which facilitates clamping the radioactive container.

[0057] In one embodiment, please refer to Figure 2 One of the clamping seat 33 and the cutting base 1 is provided with a clamping slide rail 1b, and the other of the clamping seat 33 and the cutting base 1 is provided with a clamping slider. The clamping slide rail 1b and the clamping slider are in sliding engagement.

[0058] For example, both clamping seats 33 are formed with sliders, and the cutting base 1 is formed with a clamping slide rail 1b extending in a first direction, with the sliders slidably disposed in the slide rail.

[0059] Here, through the cooperation of the clamping slide rail 1b and the clamping slider, on the one hand, the clamping slide rail 1b can provide a smooth and accurate movement path, while the clamping slider can slide easily within the clamping slide rail 1b, making the entire movement process more precise and controllable; on the other hand, the clamping slide rail 1b can provide additional support and stability, preventing the clamping slider from shaking or sliding unsteadily during the movement, resulting in good movement stability.

[0060] For example, in one embodiment, there are two clamping slide rails 1b, which are spaced apart along the second direction. The clamping seat 33 has sliders at both ends along the second direction, which can improve the stability of sliding.

[0061] In one embodiment, please refer to Figure 2 and Figure 5 The rotating device 4 includes a rotating drive assembly 41 and multiple rotating rollers 42. Each clamping seat 33 is equipped with a rotating roller 42. When two clamping seats 33 clamp the radioactive container, the rotating roller 42 is in contact with the radioactive container and can rotate around its rotation axis, which is parallel to the axis of the radioactive container. The rotating drive assembly 41 is located in any one of the clamping seats 33 and is used to drive the rotating roller 42 of the clamping seat 33 to rotate.

[0062] For example, the rotating roller 42 can be disposed on the side of the clamping seat 33 along the axial direction of the radioactive container, close to the cutting base 1 and near the notch 33a. The two clamping seats 33 are divided into a first clamping seat 331 and a second clamping seat 332, and the rotating drive assembly 41 can be disposed on the first clamping seat 331.

[0063] Here, by setting the rotary drive assembly 41 on any one of the clamping seats 33, when the radioactive container is clamped by the two clamping seats 33, the rotary rollers 42 of both clamping seats 33 will be in contact with the radioactive container. Then, the rotary drive assembly 41 drives the rotary roller 42 of the clamping seat 33 to rotate actively, and the rotary roller 42 on the other clamping seat 33 rotates as a driven roller. This allows the rotary roller 42 to drive the radioactive container to rotate around its axis through friction. This not only facilitates the circumferential cutting of the cutting device 5 and improves the cutting efficiency, but also simplifies the structure of the control rotary device 4 and reduces the cost.

[0064] In one embodiment, please refer to Figure 5 The clamping seat 33, which is provided with a rotary drive assembly 41, has at least two rotary rollers 42. The rotary drive assembly 41 includes a rotary motor 411, a plurality of rotary drive shafts 412 and a converter. The rotary motor 411 is driven to the plurality of rotary drive shafts 412 through the converter. Each rotary drive shaft 412 is driven to at least one rotary roller 42.

[0065] For example, the first clamping seat 331 may be provided with two rotating rollers 42, and the number of rotating drive shafts 412 may be two. The two rotating drive shafts 412 may be spaced apart along a second direction and extend along the second direction. The converter may be a pulley assembly, a gear assembly, or a chain. A rotary motor 411 may be connected to the converter via a rotary reducer 414 and drive the two rotating drive shafts 412, each rotating drive shaft 412 being directly or indirectly connected to a rotating roller 42.

[0066] Here, by setting a rotary motor 411 and a converter, multiple rotary transmission rods are easily driven to drive at least two rotary rollers 42 to rotate synchronously. This reduces slippage and vibration of the radioactive container, thereby improving the rotational stability of the radioactive container and enhancing its load-bearing capacity.

[0067] In one embodiment, please refer to Figure 5 The converter can be a T-type commutator 413. The rotating device 4 also includes a second coupling 43, a right-angle commutator 44, and a worm gear assembly. The converter, right-angle commutator 44, rotary motor 411, rotary drive shaft 412, second coupling 43, and worm gear assembly are all arranged on the side of the first clamping seat 331 relative to the rotating roller 42. The end of each rotary drive shaft 412 away from the converter can be connected to a right-angle commutator 44 through the second coupling 43. The end of the right-angle commutator 44 along the first direction can be connected to the rotating roller 42 located on the first clamping seat 331 through the worm gear assembly. The structure is compact.

[0068] In one embodiment, please refer to Figure 1 and Figure 3 The cutting device 5 includes a movable base 51, two supports 52, and two cutter head assemblies 53. The movable base 51 is disposed on the cutting base 1. The two supports 52 are disposed on the movable base 51. The two cutter head assemblies 53 are respectively disposed on the two supports 52. One of the two cutter head assemblies 53 is used to cut the protruding portion along the axial direction of the radioactive container, and the other is used to cut the protruding portion along the circumferential direction of the radioactive container.

[0069] For example, the movable base 51 can be a vertical base extending along the axial direction of the radioactive container. Two supports 52 can be disposed on two sides of the movable base 51 along a first direction, and two cutter head assemblies 53 are respectively disposed at the ends of the two supports 52 along a second direction.

[0070] For example, the cutter head assembly 53 may include a cutting motor 531 and a cutter head 532. The cutting motor 531 is mounted on the bracket 52 and is used to drive the cutter head 532 to rotate. The cutter head 532 may be disc-shaped.

[0071] For example, the two cutter head assemblies 53 are divided into a first cutter head assembly 53a and a second cutter head assembly 53b. The rotation axis of the cutting motor 531 of the first cutter head assembly 53a is parallel to a first direction, so that the cutter head 532 of the first cutter head assembly 53a is arranged parallel to the axial direction of the radioactive container and is used to cut the protruding portion along the axial direction of the radioactive container. The rotation axis of the cutting motor 531 of the second cutter head assembly 53b is parallel to the axial direction of the radioactive container, so that the cutter head 532 of the second cutter head assembly 53b is arranged perpendicular to the axial direction of the radioactive container.

[0072] For example, the lifting device 2 and the rotating device 4 can cooperate to enable the first cutter head assembly 53a and the second cutter head assembly 53b to cut the protruding portion along the axial and circumferential directions of the radioactive container.

[0073] In this way, the movable seat 51, the two supports 52 and the two cutter head assemblies 53 can achieve cutting in multiple directions, both axial and circumferential, to cut the protruding part into smaller pieces, which are easy to grip with a special fixture.

[0074] In one embodiment, please refer to Figure 3 The movable seat 51 is movably disposed on the cutting base 1 and is configured to be movable relative to the cutting base 1 in a first direction.

[0075] For example, a connecting seat 1c is provided on one side of the cutting base 1 along the second direction, and a movable seat 51 is movably disposed on the connecting seat 1c. For example, one of the movable seat 51 and the connecting seat 1c forms a first slide rail 1c1, and the other of the movable seat 51 and the connecting seat 1c forms a first slider 51a. Specifically, the movable seat 51 may form a first slider 51a, the connecting seat 1c may form a first slide rail 1c1, and the first slider 51a may be slidably disposed within the first slide rail 1c1.

[0076] For example, the method by which the movable seat 51 moves relative to the cutting base 1 along the first direction is not limited. For instance, it can be pushed by a robotic arm or driven by other structures. Specifically, the cutting device 5 may include a first drive assembly 54, which includes a first lead screw assembly 541 and a first motor 542. The first lead screw assembly 541 may be disposed on the connecting seat 1c, and the movable seat 51 is disposed on the nut of the first lead screw assembly 541. Driven by the first motor 542, the movable seat 51 moves along the first direction.

[0077] Here, by moving the movable seat 51 relative to the cutting base 1 along the first direction, the two cutter head assemblies 53 can be moved along the first direction to achieve cutting at different positions.

[0078] As an example, in one embodiment, please refer to Figure 3The number of first slide rails 1c1 can be two, and the two first slide rails 1c1 can be arranged at intervals along the second direction. The movable seat 51 is also provided with two first sliders 51a on both sides along the second direction, which can improve the sliding stability of the movable seat 51.

[0079] In one embodiment, please refer to Figure 3 The support 52 includes a lifting plate 521 and a connecting frame 522. The lifting plate 521 is movably disposed on the movable seat 51 and is configured to be movable relative to the movable seat 51 along the axial direction of the radioactive container.

[0080] For example, the lifting plate 521 is movably disposed on the movable seat 51. For instance, one of the movable seat 51 and the lifting plate 521 forms a second slide rail 51b, and the other of the movable seat 51 and the lifting plate 521 forms a second slider 521a. Specifically, the movable seat 51 may form a second slide rail 51b, and the lifting plate 521 may form a second slider 521a, with the second slider 521a slidably disposed within the second slide rail 51b.

[0081] For example, the method of moving the lifting plate 521 relative to the movable seat 51 along the axial direction of the radioactive container is not limited. For instance, it can be pushed by a robotic arm or driven by other structures. Specifically, the cutting device 5 may include a second drive assembly 55, which includes a second lead screw assembly 551 and a second motor 552. A third lead screw assembly 561 may be disposed on the movable seat 51. The lifting plate 521 is disposed on the nut of the second lead screw assembly 551. Driven by the second motor 552, the lifting plate 521 moves along the axial direction of the radioactive container.

[0082] Here, by moving the lifting plate 521 relative to the moving seat 51 along the axial direction of the radioactive container, the connecting frame 522 can be moved along the axial direction of the radioactive container, which in turn can move the two cutter head assemblies 53 along the axial direction of the radioactive container to achieve cutting at different positions.

[0083] As an example, in one embodiment, please refer to Figure 3 The number of second slide rails 51b can be two, and the two second slide rails 51b can be arranged at intervals along the second direction on the movable seat 51. The lifting plate 521 is also provided with two second sliders 521a on both sides along the second direction. In this way, the sliding stability of the lifting plate 521 can be improved.

[0084] In one embodiment, please refer to Figure 3 The cutter head assembly 53 is disposed on the connecting frame 522, which is movably disposed on the lifting plate 521 and configured to move relative to the lifting plate 521 in a second direction, wherein the first direction, the second direction and the axis of the radioactive container are perpendicular to each other.

[0085] For example, the cutter head assembly 53 may be disposed at the end of the connecting frame 522 along the second direction.

[0086] For example, the connecting frame 522 is movably disposed on the lifting plate 521. For instance, one of the connecting frame 522 and the lifting plate 521 forms a third slide rail 522a, and the other of the connecting frame 522 and the lifting plate 521 forms a third slider 521b. Specifically, the connecting frame 522 may form a third slide rail 522a, the lifting plate 521 may form a third slider 521b, and the second slider 521a may be slidably disposed within the third slide rail.

[0087] For example, the method by which the connecting frame 522 moves relative to the lifting plate 521 in the second direction is not limited. For instance, it can be pushed by a robotic arm or moved by other structures. Specifically, the cutting device 5 may include a third drive assembly 56, which includes a third lead screw assembly 561 and a third motor 562. The third lead screw assembly 561 may be disposed on the connecting frame 522, and the lifting plate 521 may be disposed on the nut of the third lead screw assembly 561. The lifting plate 521 moves in the second direction by being driven by the third motor 562.

[0088] Here, by moving the connecting frame 522 relative to the lifting plate 521 in the second direction, the two cutter head assemblies 53 can be moved in the second direction to achieve cutting at different positions.

[0089] It should be noted that the movement of the lifting plate 521 relative to the movable seat 51 and the movement of the connecting frame 522 relative to the lifting plate 521 are both examples of the support 52 on one side.

[0090] Here, the two cutter head assemblies 53 can cut synchronously or asynchronously.

[0091] As an example, in one embodiment, please refer to Figure 3 The number of third slide rails 522a can be two. The two third slide rails 522a can be arranged at intervals along the axial direction of the radioactive container on the connecting frame 522. The lifting plate 521 is also provided with two third sliders 521b on both sides along the axial direction of the radioactive container. In this way, the sliding stability of the connecting frame 522 can be improved.

[0092] In one embodiment, please refer to Figure 6 The cutting equipment 100 includes a control device 7, which is communicatively connected to the lifting device 2, the clamping device 3, the rotating device 4 and the cutting device 5, and is used to adjust the operating parameters of each device to perform corresponding actions.

[0093] For example, the communication connection can be a wired connection or a wireless connection. The wireless connection can be WiFi, Bluetooth, etc., while the wired connection can be protected by a drag chain 7e.

[0094] For example, the control device 7 can be communicatively connected to the motors of various devices, such as the lifting motor 211, the clamping drive motor 32, the rotary motor 411, the cutting motor 531, the slewing motor, the first motor 542, the second motor 552, and the third motor 562, etc.

[0095] For example, the control device 7 has a display screen 7a, a touch screen 7b, a power switch, an emergency stop switch, a mouse 7d, and operation buttons 7c. The touch screen 7b is used to set the operating parameters of various motors, the display screen 7a is used to monitor the cutting scene, and the mouse 7d is used to zoom in on the monitoring screen.

[0096] For example, the control device 7 may be located outside the stack.

[0097] Here, the control device 7 can control each motor to achieve the following: the first cutter head assembly 53a moves along the radioactive container; the cutter head 532 rotates forward and backward; the corresponding cutting motor 531 starts and stops; the second cutter head assembly 53b moves along the first direction, the second direction and along the axial direction of the radioactive container; the corresponding cutting motor 531 starts and stops; the disc body 221 rotates; the two clamping seats 33 clamp and release the radioactive container; the radioactive container moves along its axial direction, etc.

[0098] In this way, by setting up control device 7, the operating parameters of each device can be remotely adjusted to achieve the corresponding actions, enabling remote cutting and sampling of radioactive containers, thereby reducing the radiation dose to operators.

[0099] This application embodiment can also provide an operation process that utilizes the cutting device 100 in the above embodiment.

[0100] 1. Preparation: Before clamping the radioactive container, move the first cutter head assembly 53a and the second cutter head assembly 53b to the appropriate position to prevent interference and collision; drive the clamping transmission assembly 31 through the clamping drive motor 32 to separate the two clamping seats 33, and raise the lifting tray 22 to the highest position through the lifting transmission assembly 21.

[0101] 2. Lifting of radioactive containers: Using a special lifting tool, the radioactive container is lifted directly above the lifting tray 22 and slowly lowered onto the lifting tray 22. Then, the radioactive container is lowered into the shielding facility by the lifting transmission assembly 21. The special lifting tool is removed, and the clamping drive motor 32 drives the clamping transmission assembly 31 to clamp the radioactive container with the two clamping seats 33.

[0102] 3. Axial cutting of radioactive container: After the radioactive container is clamped and fixed, the first cutter head assembly 53a is driven to move to the initial cutting position to cut the wall of the radioactive container axially. After the cutting is completed, the first cutter head assembly 53a is driven to move to the initial cutting position. The rotating roller 42 of the clamping seat 33 is driven to rotate by the rotation drive assembly 41, which drives the radioactive container to rotate to the specified angle and then stops. The cutting and rotation actions are repeated until the circumferential cutting is completed at the specified angle. Then the first cutter head assembly 53a is driven to move to the initial position.

[0103] 4. Circumferential cutting of the radioactive container: Drive the second cutter head assembly 53b to move to the initial cutting position. With the radioactive container fixed, the second cutter head assembly 53b moves circumferentially under the action of the rotating device 4, cutting from the first axial cutting seam to the second axial cutting seam, completing one cut. Use a special clamp to remove the cut slice. The second cutter head assembly 53b moves to the initial cutting position again. The rotating device 4 is activated, causing the radioactive container to rotate at a specified angle, and the next cut begins. Repeat the above actions until the entire segment is cut. Finally, lift a segment of the radioactive container out of the cutting opening 1a for repeated cutting.

[0104] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, and improvements made within the spirit and scope of this application are included within the scope of protection of this application.
