[0021] Exemplary embodiments of this application will be described below with reference to the accompanying drawings. For clarity and brevity, not all features of actual implementations are described in the specification. However, it should be understood that many implementation-specific decisions must be made in the development of any such actual embodiment to achieve the developer's specific goals, such as complying with constraints related to the system and business, and these constraints may vary depending on the implementation. Furthermore, it should be understood that while development work can be very complex and time-consuming, such development work is merely a routine task for those skilled in the art who benefit from the content of this application.

[0022] It should also be noted that, in order to avoid obscuring this application with unnecessary details, only the equipment structure and / or processing steps closely related to the solution according to this application are shown in the accompanying drawings, while other details that are not closely related to this application are omitted.

[0023] The cold crucible needs to be positioned directly beneath the calcination furnace for radioactive waste during operation to ensure its proper functioning and to effectively contain the toxic and hazardous components of the radioactive waste within the glass. Due to the high radiation intensity from the radioactive waste within the cold crucible, manual operation is impossible; remote operation using mechanical equipment is required. However, the space directly beneath the furnace during operation is quite confined, making disassembly, assembly, or maintenance difficult.

[0024] To address at least one aspect of the aforementioned technical problems, embodiments of this application provide a support and mobility device for a high-level radioactive wastewater treatment equipment, such as... Figure 1The diagram shows a schematic representation of the structure of the device 100 provided in an embodiment of this application when connected to the cold crucible 200 and the track 300. The high-level radioactive waste treatment equipment includes a cold crucible 200. The device 100 supports the cold crucible 200 when it is in the working position and moves it to the maintenance position when needed. A track 300 is provided between the working position and the maintenance position. The device 100 provided in the embodiment of this application includes a device body 10, a moving component 20, and a driving component 30. The device body 10 is configured to support the cold crucible 200 in both the working and maintenance positions. The moving component 20 is fixedly disposed below the device body 10. The driving component 30 is disposed on the device body 10 and configured to drive the moving component 20, causing the device 100 to move along the track 300 between the working position and the maintenance position.

[0025] The device 100 provided in the embodiments of this application can be used to support the cold crucible 200 when it is working or being repaired, and can also be used to move the cold crucible 200 between the repair station and the working station. When maintaining the cold crucible 200, it can be moved to a repair station that meets the operating space requirements, which facilitates remote maintenance of the cold crucible 200 and can solve the problem of insufficient operating space when remotely operating the cold crucible 200.

[0026] In some embodiments, the device body 10 may further include a support plate 11, which may be configured to support the cold crucible 200. A first frame structure 12 and a second frame structure 13 may be provided on both sides of the support plate 11, and the first frame structure 12 and the second frame structure 13 may be fixedly connected to the support plate 11.

[0027] like Figure 2 As shown, it illustrates the structural diagram of the connection between the device body 10, the moving component 20, and the driven module 32 provided in the embodiments of this application. In some embodiments, a mounting hole 111 may be formed in the support plate 11, and a positioning guide structure 112 may be formed around the mounting hole 111. The bottom plate of the cold crucible 200 may be installed in the mounting hole 111 and located in the positioning guide structure 112.

[0028] In some embodiments, the mounting hole 111 may be a groove that matches the cold crucible 200 and can be used to mount the cold crucible 200 onto the support plate 11. The positioning guide structure 112 can guide the installation of the cold crucible 200 and provide assistance during the installation process. The structure and distribution of the mounting hole 111 and the positioning guide structure 112 can be matched with the structure of the cold crucible 200.

[0029] like Figure 6As shown, it illustrates a structural diagram of the connection between the device body 10 and the drive component 30 and the moving component 20 provided in the embodiments of this application. In some embodiments, the drive component 30 may include an active module 31 and a driven module 32. The active module 31 may be fixedly mounted on the support plate 11, and the driven module 32 may be fixedly connected to the end of the first frame structure 12 and the end of the second frame structure 13. The active module 31 may drive the driven module 32 to move, and the driven module 32 may drive the moving component 20 to move.

[0030] like Figure 4 As shown, it illustrates the structural schematic diagram of the active module 31 provided in the embodiment of this application. The active module 31 may include a mounting base 311, a mounting plate 312, a drive unit 313, an active gear 314, a pull rod structure 315, a guide device 316, and a limiting rod 317. The mounting base 311 can be mounted on the support plate 11; the mounting plate 312 can be mounted on the mounting base 311; the drive unit 313 can drive the drive gear 314 to move, and the drive unit 313 and the drive gear 314 can be mounted on the mounting plate 312; the tie rod structure 315 can be disposed between the drive unit 313 and the drive gear 314, and can be fixed on the mounting plate 312; the guide device 316 can be disposed on the mounting base 311, and can form a groove with the mounting base 311, allowing the mounting plate 312 to slide within the groove; the limiting rod 317 can be detachably mounted on the mounting base 311, and when the limiting rod 317 is mounted on the mounting base 311, it can limit the mounting plate 312. The mounting plate 312 can be moved out of or installed into the mounting base 311 via the tie rod structure 315. The tie rod structure 315 and the limiting rod 317 can be remotely operated using remote tools.

[0031] In some embodiments, the mounting base 311 can be a multi-layer structure, and the height of the mounting base 311 is the same as the height between the support plate 11 and the driven shaft 321, so that the driven gear 322 and the driving gear 314 can be on the same plane, which facilitates the driving gear 314 to drive the driven gear 322 to move. The mounting base 311 can be composed of two mounting base plates and a connecting column disposed between the mounting base plates. One of the mounting base plates is also provided with a mounting hole, through which the mounting base 311 can be installed onto the support plate 11.

[0032] In some embodiments, the active module 31 may also include a plurality of limiting devices 318, which may be disposed at both ends of the mounting base 311 to limit the position of the mounting plate 312; the active module 31 may also include a reducer 319, which may be connected to the drive unit 313, and the reducer 319 may control the rotation speed of the active gear 314, thereby controlling the moving speed of the device 100.

[0033] like Figure 5a , Figure 5b , Figure 5c As shown, Figure 5a This diagram illustrates the structure of the mounting plate as it begins to be removed from the mounting base according to an embodiment of this application. Figure 5b This diagram illustrates the structural details of the process by which the mounting plate is removed from the mounting base according to an embodiment of this application. Figure 5c This diagram illustrates the structure of the mounting plate being removed from the mounting base according to an embodiment of this application. The specific process of removing the mounting plate 312 from the mounting base 311 is as follows:

[0034] First, using a remote tool to remotely operate the limiting rod 317, the limiting rod 317 is lifted and placed at the limiting rod hole 3171. At this time, the fixed state of the mounting plate 312 is released, and the mounting plate 312 can move. Next, the pull rod structure 315 can be gripped by a robotic arm, and the pull rod structure 315 can drive the mounting plate 312 to move. By pulling the pull rod structure 315, the mounting plate 312 is translated along the length direction of the guide device 316. The mounting plate 312 can slide in the groove of the guide device 316, and the meshing state of the drive gear 314 and the driven gear 322 is released. This allows the mounting plate 312, as well as the drive unit 313, reducer 319, drive gear 314, and pull rod structure 315 mounted on the mounting plate 312, to be moved together, facilitating equipment replacement as needed.

[0035] In some embodiments, when the drive unit 313 needs maintenance, the active module 31 can be completely removed and repaired by dragging the lever structure 315 with a robotic arm.

[0036] In some embodiments, the driven module 32 may include a driven gear 322 and a driven shaft 321. The driven gear 322 may be disposed on the driven shaft 321. Both ends of the driven shaft 321 may be fixed to the first frame structure 12 and the second frame structure 13. The driving gear 314 may drive the driven gear 322 to move, the driven gear 322 may drive the driven shaft 321 to move, and the driven shaft 321 may drive the moving component 20 to move.

[0037] In some embodiments, the movable component 20 may be fixedly disposed at both ends of the first frame structure 12 and the second frame structure 13.

[0038] In some embodiments, the moving component 20 may include a roller 21 and auxiliary wheels 22 located on both sides of the roller 21. The roller 21 can slide on the track 300, and the auxiliary wheels 22 can slide on both sides of the track 300. The sliding of the roller 21 can be limited, which can ensure the stability of the device 100 during the movement along the track 300.

[0039] In some embodiments, the device 100 may further include a limiting part 50 disposed on the device body 10, and a limiting part cooperating part 60 disposed at the working station and maintenance station of the track 300. The limiting part 50 may cooperate with the limiting part cooperating part 60 to make the device 100 stable at the working station or maintenance station.

[0040] In some embodiments, the limiting part 50 may include a limiting member 51 and a limiting member fixing part 52. The limiting member 51 may be disposed in the limiting member fixing part 52. The limiting member fixing part 52 may be disposed at both ends of the first frame structure 12 and the second frame structure 13. The limiting member fixing part 52 may be a hollow structure and have an open end. A portion of the limiting member 51 may extend into the hollow structure.

[0041] The limiting part mating part 60 may include a limiting member mating part 61 and a stop member 62. The limiting member mating part 61 can be fixed to the stop member 62, and the limiting member mating part 61 may be provided with a limiting hole 611. When the limiting part 50 and the limiting part mating part 60 are mated, the limiting member mating part 61 can enter the hollow structure of the limiting member fixing part 52, the limiting member fixing part 52 can abut against the stop member 62, and the limiting member 51 can extend into the limiting hole 611. The device 100 can be positioned by the mating of the limiting part 50 and the limiting part mating part 60 to ensure that the device 100 can run along the track 300 to a designated position, and the position of the device 100 can be constrained.

[0042] In some embodiments, the limiting member 51 may also be provided with an anti-loosening nut 511 and a locking nut 512. The movement of the limiting member 51 can be restricted by the anti-loosening nut 511 and the locking nut 512 to fix the limiting member 51. The limiting member fixing part 52 may also be formed with a through hole 521, and the limiting member 51 can enter the through hole 521.

[0043] like Figure 3a and Figure 3b As shown, Figure 3a This is a schematic diagram showing a cooperative state of the limiting part 50 and the limiting part mating part 60 provided in an embodiment of this application. Figure 3bThis diagram illustrates another cooperative state of the limiting part 50 and the limiting part mating part 60 provided in an embodiment of this application. Taking the process of the device 100 moving from the working station to the maintenance station as an example, the specific process of the cooperation between the limiting part 50 and the limiting part mating part 60 during this movement is as follows: As the device 100 moves along the track 300, the limiting member mating part 61 of the limiting part mating part 60 enters the hollow structure of the limiting member fixing part 52. When the limiting member fixing part 52 abuts against the stop member 62, the device 100 reaches the designated position of the maintenance station and stops moving. Then, the anti-loosening nut 511 and the locking nut 512 are loosened, and the limiting member 51 moves downward. When the limiting member 51 passes through the through hole 521 of the limiting member fixing part 52 and enters the limiting hole of the limiting member mating part 61, the anti-loosening nut 511 and the locking nut 512 are tightened, and the limiting member 51 is fixed and can no longer move. At this time, the limiting part 50 and the limiting part mating part 60 are both fixed by the limiting member 51, the position of the device 100 is fixed, and the positioning of the device 100 is completed to ensure the stability of the device 100 in the maintenance station.

[0044] In some embodiments, the device 100 may also include a plurality of auxiliary moving devices 40, which may be installed at both ends of the first frame structure 12 and the second frame structure 13 for operation by a robotic arm to realize the overall movement and replacement of the device 100, so that the device 100 can have good maintainability.

[0045] In some embodiments, the moving component 20 can be replaced to match different types of tracks 300.

[0046] The process of moving a cold crucible 200 from a working station to a maintenance station using the apparatus 100 provided in the embodiments of this application is described in detail below with reference to specific embodiments.

[0047] First, the device 100 is installed on the track 300, and the cold crucible 200 is installed on the device 100. Next, the drive unit 313 is activated, which drives the driving gear 314 to rotate. The driving gear 314 drives the driven gear 322 to rotate, the driven gear 322 drives the driven shaft 321 to rotate, and the driven shaft 321 drives the roller 21 connected to it to rotate. The device 100 begins to move along the track 300. Then, the track 300 moves to the maintenance station, and the limiting part 60 engages with the limiting part 60. 1. Entering the hollow structure of the limiting member fixing part 52, when the limiting member fixing part 52 abuts against the stop member 62, the device 100 reaches the designated position of the maintenance station and stops moving; then, loosening the anti-loosening nut 511 and the locking nut 512, the limiting member 51 moves downward. When the limiting member 51 passes through the through hole 521 of the limiting member fixing part 52 and enters the limiting hole of the limiting member mating part 61, the anti-loosening nut 511 and the locking nut 512 are tightened, and the limiting member 51 is fixed and can no longer move. At this time, the limiting part 50 and the limiting part mating part 60 are both fixed by the limiting member 51, and the positions of the device 100 and the cold crucible 200 are fixed; then, the cold crucible 200 can be maintained by a robot arm.

[0048] The device 100 provided in the embodiments of this application can be used to move the cold crucible 200 in a radioactive environment, and can realize remote maintenance and rapid disassembly and assembly of the cold crucible 200.

[0049] Regarding the embodiments of this application, it should also be noted that, without conflict, the embodiments of this application and the features in the embodiments can be combined with each other to obtain new embodiments.
