Description

Technical Field

[0001] This invention relates to the field of equipment for transferring items in nuclear facility compartments, and more specifically to transfer equipment. Background Technology

[0002] In the nuclear industry, enclosures are special sealed spaces used to handle radioactive materials, and the transfer of materials between these enclosures and the outside environment is a critical technology. During the transfer process, it is essential to ensure not only the smooth transfer of materials but also a good shielding effect between the hot chamber and the outside environment.

[0003] Existing transfer equipment has some shortcomings in structural design and functional implementation, and cannot efficiently and reliably meet the requirements for item transfer and shielding. The shielding performance needs to be further improved. Summary of the Invention

[0004] This invention provides a transfer device to solve the problem of insufficient shielding in existing transfer devices.

[0005] This invention provides a transfer device disposed in a hot chamber wall, the transfer device penetrating the wall to form openings on both sides of the wall, the transfer device comprising: The frame structure includes a frame body fixedly installed in the wall and a sealed door movably installed on the frame body, the sealed door being used to open or close openings on both sides of the wall; A rotating body, which rotates around its own axis, is disposed within the main frame body, and a transfer chamber with an opening on one side and closed on all four sides is disposed within the rotating body; A drive mechanism, connected to the rotating body, is adapted to drive the rotating body to rotate between the receiving position corresponding to the opening of the transfer chamber and the feeding position corresponding to the opening of the transfer chamber and the opening of the wall on the other side.

[0006] Beneficial effects: The sealing effect of the transfer device is effectively guaranteed by the setting of the sealed doors on both sides, preventing the leakage of radioactive materials. By opening a transfer chamber with four sides closed on one side of the rotating body, the two sealed doors are not connected, which enhances the shielding effect between the openings on both sides of the wall. The rotating body is driven by the drive structure to rotate, so that the opening of the transfer chamber rotates between the receiving position and the feeding position. The movement process of the rotating body is simple and has high transfer efficiency.

[0007] During the transfer process, the drive structure drives the rotating body to rotate, causing the opening of the transfer chamber to rotate to the receiving position corresponding to the opening on one side of the wall, thus transporting the items to be transferred into the transfer chamber. After the transfer process is completed, the drive device continues to drive the rotating body to rotate, causing the opening of the transfer chamber to rotate to the feeding position corresponding to the opening on the other side of the wall, thus transporting the transferred items out of the transfer chamber.

[0008] In one alternative embodiment, the rotating body is cylindrical or spherical, the transfer chamber is configured as a non-through channel opened radially along the rotating body, and the inner cavity of the frame structure is configured to match the shape of the rotating body.

[0009] Beneficial effects: By setting the rotating body to a cylindrical or spherical shape and matching the shape of the inner cavity of the frame structure with the shape of the rotating body, the rotating body can maintain a consistent fit with the shape of the inner cavity of the frame structure during rotation, reducing the gap between the rotating body and the frame structure, improving the shielding and sealing performance of the transfer equipment. Setting the transfer chamber as a non-through channel ensures that the rotating body can act as a barrier between the openings on both sides of the wall when it rotates to any position, and the openings on both sides of the wall will not be through, achieving a better shielding effect.

[0010] In one optional embodiment, frame channels are formed at both ends of the frame structure, and the frame channels are located between the rotating body and the sealing door; when the rotating body rotates to the receiving position or the feeding position, the frame channels are connected to the transfer bin to form a transfer channel.

[0011] Beneficial effects: By connecting the frame channel with the transfer warehouse to form a transfer channel, the transfer of items between the two sides of the wall can be completed without opening a channel that runs through the wall, effectively preventing the leakage of radioactive materials during the transfer of items.

[0012] In one optional embodiment, the transfer device further includes an item handling mechanism, which is used to transfer items between the transfer bin and the frame channel when the rotating body rotates to the receiving position or the feeding position.

[0013] Beneficial effects: By setting up an item handling mechanism, the transfer of items between the transfer compartment and the frame channels on both sides can be realized. In coordination with the rotational motion of the rotating body, the transfer of items can be achieved.

[0014] In one optional embodiment, the item handling mechanism includes: a guide rail structure disposed within the transfer chamber and the frame channel; and a transfer trolley capable of moving along the guide rail structure. When the rotating body rotates to the receiving position or the feeding position, the guide rail structure in the transfer chamber engages with the guide rail structure in the frame channel, and the transfer trolley transfers items between the transfer chamber and the frame channel along the guide rail structure.

[0015] Beneficial effects: Through the guide rail structure and trolley, items can be transferred from the openings on both sides of the wall to the junction of the frame channel and the rotating body, as well as between the frame channel and the transfer chamber. When the rotating body rotates to the receiving position, the guide rail structure in the transfer chamber connects with the guide rail structure in the frame channel on the receiving side, transporting the items into the transfer chamber. When the rotating body rotates to the feeding position, the guide rail structure in the transfer chamber connects with the guide rail structure in the frame channel on the feeding side, transferring the items into the frame channel. The transfer process is convenient and fast.

[0016] In one alternative embodiment, the frame structure further includes a shielding block disposed on the side of the frame body near the hot chamber cavity, the shielding block and the sealing door together sealing the opening on the side of the wall near the hot chamber cavity.

[0017] Beneficial effects: Setting a shielding block on the side of the frame body near the hot chamber cavity, together with the sealing door, to seal the opening on the side of the wall near the hot chamber cavity can improve the overall shielding effect of the transfer equipment. It can also seal the gap between the rotating body and the frame structure, preventing radioactive materials from leaking into the other chamber through the gap between the rotating body and the frame structure. It has a good shielding and sealing effect. In addition, the shielding block is set between the outer wall of the frame channel and the wall, which can play a supporting role.

[0018] In one optional embodiment, the drive mechanism includes a worm gear and a worm, the worm gear meshing with the worm and the worm gear being fixed to the rotating body. During the rotation of the rotating body, the worm drives the worm gear to rotate, and the worm gear drives the rotating body to rotate.

[0019] Beneficial effects: By using worm gears and worms for transmission, the high speed and low torque of the drive motor can be converted into low speed and high torque, providing the power required to adapt to the rotation of the rotating body. Moreover, the worm gear mechanism has good self-locking performance, which can accurately control the rotation angle and position of the rotating body, and plays a reliable locking role when the revolving door stops rotating. In addition, the worm gear transmission can make the rotating body run smoothly, and the entire drive device occupies less space.

[0020] In one optional embodiment, the worm gear is a sector-shaped worm gear, with limit baffles at both ends and limit blocks on the frame structure. When the rotating body rotates to the receiving position, the limit baffle at one end abuts against one side of the limit block. When the rotating body rotates to the feeding position, the limit baffle at the other end abuts against the other side of the limit block.

[0021] Beneficial effects: By setting the worm gear as a sector-shaped worm gear and setting limit baffles at both ends of the worm gear, and setting limit blocks on the frame structure, the rotational displacement of the rotating body can be limited by the limit baffles and limit blocks when the rotating body rotates to the receiving position or the feeding position, so that the transfer bins can be connected to the frame channels at both ends respectively, ensuring the positioning accuracy of the rotating body.

[0022] In one optional embodiment, the transfer device further includes a position detection mechanism, which includes a detection terminal disposed on the worm gear and a sensor fixed on the frame structure; when the rotating body rotates to the receiving position or the feeding position, the detection terminal triggers the sensor to generate a positioning signal.

[0023] Beneficial effects: The position detection mechanism detects the rotational position and status of the rotating body and transmits the signal to the electronic control system, so that the electronic control system can control and monitor the operation of the revolving door. When the rotating body is in different positions, the position detection mechanism can send corresponding signals in a timely manner, which can more accurately determine whether the rotating body has rotated into place, ensuring the safety and reliability of the transport. The terminal to be detected is set on the worm gear, which makes it easy to detect the rotation of the rotating body, and no additional structure is required to install the terminal to be detected.

[0024] In one alternative embodiment, the transfer device further includes an electronic control system, and the drive mechanism includes a drive motor. The electronic control system controls the drive motor to operate based on the positioning signal detected by the sensor.

[0025] Beneficial effects: By setting up an electronic control system, the drive motor can be controlled to work based on the position signal detected by the sensor, which can improve control flexibility, increase the automation level of the system, realize the cooperation between the position detection mechanism and the drive mechanism, and facilitate intelligent management and control of the transfer equipment.

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] The following is combined with Figures 1 to 9 The following describes embodiments of the present invention.

[0031] like Figures 1 to 9 According to an embodiment of the present invention, a transfer device is provided, disposed in the wall of a hot chamber, the transfer device penetrating the wall to form openings on both sides of the wall, the transfer device comprising: a frame structure 1, a rotating body 2, and a drive mechanism. The frame structure 1 includes a frame main body fixedly disposed within the wall, and a sealing door movably mounted on the frame main body, the sealing door being used to open or close the openings on both sides of the wall; the rotating body 2 rotates around its own axis and is disposed within the frame main body, the rotating body 2 having a transfer chamber with one side opening and all four sides closed; the drive mechanism is connected to the rotating body 2 and is adapted to drive the rotating body 2 to rotate between a receiving position corresponding to the opening on one side of the wall and a feeding position corresponding to the opening on the other side of the wall.

[0032] Specifically, the frame structure 1 includes the frame body and the rotating door frame 4.

[0033] Specifically, the main frame includes: a door frame 101, a door frame panel 102, a cover plate, a sealing door, side panels 107, and horizontal plates 108. The door frame 101 is located at an opening on one side of the wall, and the door frame 101 is an annular door frame 101 connected to the wall; the door frame panel 102 is fixed to the door frame 101; the cover plate includes a first cover plate 103 and a second cover plate 104, which are respectively located at openings on both sides of the wall, and the first cover plate 103 is connected to the door frame panel 102; the sealing door includes a first sealing door 105 and a second sealing door 106, the first sealing door 105 is connected to the first cover plate 103, and the second sealing door 106 is connected to the second cover plate 104; there are two side panels 107, which define the horizontal boundaries of the frame structure 1 and are connected to the door frame 101; there are two horizontal plates 108, which define the vertical boundaries of the frame structure 1 and are connected to the door frame 101.

[0034] Specifically, the door frame 101 is fixed to the door frame panel 102 by multiple bolts, and a sealing ring is provided between the door frame 101 and the door frame panel 102 to ensure sealing performance.

[0035] Specifically, the door frame panel 102 and the second cover plate 104 are connected by multiple bolts, and a sealing ring is provided between the door frame panel 102 and the second cover plate 104 to ensure sealing performance.

[0036] Specifically, a first sealing ring 112 is provided between the first sealing door 105 and the first cover plate 103, and a second sealing ring 113 is provided between the second sealing door 106 and the second cover plate 104.

[0037] Specifically, the side plate 107 and the cross plate 108 are connected to the door frame 101 by bolts.

[0038] Specifically, multiple anchor bolts 114 are connected to the door frame 101.

[0039] Specifically, the components in the transfer equipment that come into contact with the hot chamber environment are made of stainless steel, while other components are made of carbon steel.

[0040] In this embodiment, the sealing effect of the transfer device is effectively guaranteed by the setting of the sealing doors on both sides, preventing the leakage of radioactive materials. By opening a transfer chamber with four sides closed on one side of the rotating body 2, the sealing doors on both sides are not through-hole structures, which enhances the shielding effect between the openings on both sides of the wall. The rotating body 2 is driven to rotate by the driving structure 5, so that the opening of the transfer chamber rotates between the receiving position and the feeding position. The movement process of the rotating body 2 is simple and has high transfer efficiency.

[0041] During the transfer process, the drive structure 5 drives the rotating body 2 to rotate, so that the opening of the transfer chamber rotates to the receiving position corresponding to the opening on one side of the wall, and the items to be transferred are transported into the transfer chamber. After the transfer process is completed, the drive device continues to drive the rotating body 2 to rotate, so that the opening of the transfer chamber rotates to the feeding position corresponding to the opening on the other side of the wall, and the items to be transferred are transported out of the transfer chamber.

[0042] like Figure 1 As shown, in one embodiment, the rotating body 2 is cylindrical or spherical, the transfer chamber is configured as a non-through channel opened radially along the rotating body 2, and the inner cavity of the frame structure 1 is configured to match the shape of the rotating body 2.

[0043] In a preferred embodiment, the rotating body 2 is configured as a cylinder.

[0044] In this embodiment, the rotating body 2 is set to be cylindrical or spherical, and the inner cavity of the frame structure 1 is set to match the shape of the rotating body 2. This allows the rotating body 2 to maintain a consistent shape with the inner cavity of the frame structure 1 during rotation, reducing the gap between the rotating body 2 and the frame structure 1, and improving the shielding and sealing performance of the transfer equipment. Setting the transfer chamber as a non-through channel ensures that the rotating body 2 can act as a barrier between the openings on both sides of the wall when it rotates to any position. The openings on both sides of the wall will not be through, thus achieving a better shielding effect.

[0045] like Figure 1 As shown, in one embodiment, the two ends of the frame structure 1 form a frame channel, which is located between the rotating body 2 and the sealing door; when the rotating body 2 rotates to the receiving position or the feeding position, the frame channel connects with the transfer chamber to form a transfer channel.

[0046] In this embodiment, a transfer channel is formed by connecting the frame channel with the transfer warehouse, which can complete the transfer of items between the two sides of the wall without opening a channel that runs through the wall, effectively preventing the leakage of radioactive materials during the transfer of items.

[0047] like Figure 1 and Figure 8 As shown, in one embodiment, the transfer device further includes an item handling mechanism, which is used to transfer items between the transfer bin and the frame channel when the rotary body 2 rotates to the receiving position or the feeding position.

[0048] In this embodiment, an item handling mechanism is set up to realize the transfer of items between the transfer warehouse and the two side frame channels. The transfer of items is achieved in conjunction with the rotational motion of the rotating body 2.

[0049] like Figure 1 and Figure 8 As shown, in one embodiment, the item handling mechanism includes a guide rail structure 31 and a transfer trolley 32. The guide rail structure 31 is disposed within the transfer chamber and the frame channel; the transfer trolley 32 can move along the guide rail structure 31. When the rotary body 2 rotates to the receiving position or the feeding position, the guide rail structure 31 in the transfer chamber mates with the guide rail structure 31 in the frame channel, and the transfer trolley 32 transfers items between the transfer chamber and the frame channel along the guide rail structure 31.

[0050] Specifically, the guide rail structure 31 includes a guide rail and a guide rail mounting plate, and the transfer trolley 32 moves on the guide rail.

[0051] Specifically, the guide rail structure 31 is divided into three parts. The first part is set in the frame channel on one side near the first sealing door 105, including the first guide rail 311 and the first guide rail mounting plate 312. The second part is set in the transfer chamber, including the second guide rail 313 and the second guide rail mounting plate 314. The third part is set in the frame channel on one side blocked by the second sealing door 106, including the third guide rail 315 and the third guide rail mounting plate 316.

[0052] Specifically, the first guide rail 311, the second guide rail 313, and the third guide rail 315 are respectively fixed to the first guide rail mounting plate 312, the second guide rail mounting plate 314, and the third guide rail mounting plate 316 by multiple bolts. The first guide rail mounting plate 312 and the third guide rail mounting plate 316 are respectively fixed to the door frames 41 on both sides by multiple bolts, and the second guide rail mounting plate 314 is fixed to the rotating body 2 by multiple bolts.

[0053] In this embodiment, the guide rail structure 31 and the trolley enable the transfer of items from the openings on both sides of the wall to the junction of the frame channel and the rotating body 2, as well as the transfer of items between the frame channel and the transfer chamber. When the rotating body 2 rotates to the receiving position, the guide rail structure 31 in the transfer chamber connects with the guide rail structure 31 in the frame channel on the receiving side, transporting the items into the transfer chamber. When the rotating body 2 rotates to the feeding position, the guide rail structure 31 in the transfer chamber connects with the guide rail structure 31 in the frame channel on the feeding side, transferring the items into the frame channel. The transfer process is convenient and fast.

[0054] like Figures 1 to 3 As shown, in one embodiment, the frame structure 1 further includes a shielding block disposed on the side of the frame body near the hot chamber cavity, and the shielding block and the sealing door together seal the opening on the side of the wall near the hot chamber cavity.

[0055] Specifically, the shielding block includes a first shielding block 109, a second shielding block 110, and a third shielding block 111.

[0056] Specifically, there are two first shielding blocks 109, each of which is corresponding to a side plate 107. One end of the first shielding block 109 is connected to the side plate 107, and together with the side plate 107, they form the horizontal boundary of the frame structure 1.

[0057] Specifically, there are two second shielding blocks 110, each of which is corresponding to a horizontal plate 108. One end of the second shielding block 110 is connected to the horizontal plate 108, and together with the horizontal plate 108, they form the boundary of the frame structure 1 in the vertical direction.

[0058] Specifically, the third shielding block 111 is an annular shielding block. The inner side of the third shielding block 111 is connected to the second sealing door 106 and abuts against the outer wall of the frame channel. The outer side of the third shielding block 111 is connected to the second shielding block 110.

[0059] Specifically, the side plate 107 is connected to the first shielding block 109 by bolts, the horizontal plate 108 is connected to the second shielding block 110 by bolts, and the second shielding block 110 is connected to the third shielding block 111 by bolts. The first shielding block 109, the second shielding block 110 and the third shielding block 111 are all made of carbon steel.

[0060] In this embodiment, a shielding block is set on the side of the frame body near the hot chamber cavity, which together with the sealing door seals the opening on the side of the wall near the hot chamber cavity. This can improve the overall shielding effect of the transfer equipment and seal the gap between the rotating body 2 and the frame structure 1, preventing radioactive materials from leaking into the other chamber through the gap between the rotating body 2 and the frame structure 1. It has a good shielding and sealing effect. In addition, the shielding block is set between the outer wall of the frame channel and the wall, which can play a supporting role.

[0061] like Figure 1 , Figure 5 and Figure 6 As shown, in one embodiment, the drive mechanism includes a worm gear 52 and a worm 53. The worm gear 52 meshes with the worm 53 and is fixed to the rotating body 2. During the rotation of the rotating body 2, the worm 53 drives the worm gear 52 to rotate, and the worm gear 52 drives the rotating body 2 to rotate.

[0062] Specifically, when the transfer equipment is working, the drive mechanism is driven by the worm gear 52 and worm 53 to rotate the rotating body 2 by 180 degrees, thus completing the transfer of the items.

[0063] Specifically, the drive structure 5 includes: a drive motor 51, a reducer, a coupling, bearings, a worm gear 52, a worm 53, and a drive shaft 54. The drive shaft 54 ​​is connected to the drive motor 51 via a first coupling 55, and the drive shaft 54 ​​is connected to the worm 53 via a second coupling 56.

[0064] Specifically, the worm 53 is supported at both ends by the first support 58 and the second support 59.

[0065] Specifically, the drive motor 51 is fixed to the motor bracket 57 by multiple bolts.

[0066] Specifically, the worm gear 52 is fixed to the bottom wall of the rotating body 2 by multiple bolts, and the worm gear 52 is coaxially arranged with the rotating body 2.

[0067] Specifically, a receiving cavity is provided inside the wall, the drive motor is located inside the receiving cavity, and a fourth shielding block 8 is provided in the wall between the receiving cavity and the hot chamber cavity. The fourth shielding block 8 is made of carbon steel.

[0068] Specifically, the revolving door frame 4 includes: a door frame 41, a revolving door frame upper cover 42, a revolving door frame lower cover 43, and a bearing upper pressure cover 44. Two door frames 41 are provided, respectively abutting against the door frame panel 102 and the third shielding block 111; the revolving door frame upper cover 42 is provided with a first bearing, and the revolving door frame upper cover 42 is connected and fixed to the door frame 41; the revolving door frame lower cover 43 is provided with a second bearing, the second bearing being coaxially arranged with the first bearing, and the revolving door frame lower cover 43 is connected and fixed to the door frame 41; the bearing upper pressure cover 44 is located above the first bearing and is fixed to the revolving door frame upper cover 42.

[0069] Specifically, the revolving door frame 4 is made of cast steel.

[0070] Specifically, the upper cover 42 and the lower cover 43 of the rotating door frame are respectively connected and fixed to the door frame 41 by multiple bolts, and the upper cover 44 of the bearing is connected and fixed to the upper cover 42 of the rotating door frame by multiple bolts. Specifically, a sealing ring is provided between the third shielding block 111 and the door frame 41, and a sealing ring is provided between the door frame 41 and the outer wall of the frame channel.

[0071] In this embodiment, the high speed and low torque of the drive motor 51 can be converted into low speed and high torque through the transmission of the worm gear 52 and worm 53, providing the power required to adapt to the rotation of the rotating body 2. Moreover, the worm gear mechanism has good self-locking performance, which can accurately control the rotation angle and position of the rotating body 2, and play a reliable locking role when the revolving door stops rotating. In addition, the transmission of the worm gear 52 and worm 53 can make the rotating body 2 run smoothly, and the entire drive device occupies less space.

[0072] like Figure 5 and Figure 6 As shown, in one embodiment, the worm gear 52 is a sector-shaped worm gear, and limit baffles 521 are provided at both ends of the worm gear 52. Limit blocks 431 are provided on the frame structure 1. When the rotating body 2 rotates to the receiving position, the limit baffle 521 at one end abuts against one side of the limit block 431. When the rotating body 2 rotates to the feeding position, the limit baffle 521 at the other end abuts against the other side of the limit block 431.

[0073] Specifically, the limit stop 431 is fixed to the lower cover 43 of the rotating door frame by bolts, and the limit baffle is fixed to the worm gear 52 by bolts.

[0074] In this embodiment, the worm gear 52 is configured as a sector-shaped worm gear and limit baffles 521 are set at both ends of the worm gear 52. Limit blocks 431 are set on the frame structure 1. When the rotating body 2 rotates to the receiving position or the feeding position, the rotational displacement of the rotating body 2 is restricted by the limit baffles 521 abutting against the limit blocks 431, so that the transfer bins are respectively connected to the frame channels at both ends, ensuring the positioning accuracy of the rotating body 2.

[0075] like Figure 1 and Figures 5 to 7 As shown, in one embodiment, the transfer device further includes a position detection mechanism 6, which includes a detection terminal 61 disposed on the worm gear 52 and a sensor 62 fixed on the frame structure 1; when the rotating body 2 rotates to the receiving position or the feeding position, the detection terminal 61 triggers the sensor 62 to generate an arrival signal.

[0076] Specifically, sensor 62 is fixed on sensor bracket 63, and sensor bracket 63 is fixed to the lower cover 43 of the rotating door frame by bolts.

[0077] Specifically, the position detection mechanism includes two terminals 61 to be detected and two sensors 62, with the included angle between the two sensors 62 being 90 degrees and the included angle between the two terminals 61 to be detected being 90 degrees.

[0078] In this embodiment, the position detection mechanism 6 detects the rotation position and state of the rotating body 2 and transmits the signal to the electronic control system 7 so that the electronic control system 7 can control and monitor the operation of the revolving door. When the rotating body 2 is in different positions, the position detection mechanism 6 can send corresponding signals in a timely manner, which can more accurately determine whether the rotating body 2 has rotated into place, ensuring the safety and reliability of the transfer. The detection terminal 61 is set on the worm gear 52, which can facilitate the detection of the rotation of the rotating body 2, and no additional structure is required to install the detection terminal 61.

[0079] like Figure 9 As shown, in one embodiment, the transfer device further includes an electronic control system 7, and the drive mechanism includes a drive motor 51. The electronic control system 7 controls the drive motor 51 to work according to the positioning signal detected by the sensor 62.

[0080] Specifically, two sensors 62 are installed on the lower cover 43 of the revolving door sleeve, namely the first sensor and the second sensor. The two sensors 62 work together to detect the position signal. When the drive motor 51 drives the rotating body 2 to rotate, when the rotating body 2 rotates to the side where the second sealing door 106 is located, the first sensor detects the position signal, but the second sensor does not detect the position signal, and the drive motor 51 stops working. When the rotating body 2 needs to rotate to the side of the first sealing door 105, the drive motor 51 drives the rotating body 2 to rotate in the opposite direction. When the rotating body 2 rotates to the position, the first sensor does not detect the position signal, but the second sensor detects the position signal, and the drive motor 51 stops working. When the rotating body 2 rotates to the middle position, there is a situation where the first sensor and the second sensor detect the position signal at the same time. In this case, the drive motor 51 does not respond.

[0081] Specifically, the control requirements for the transfer equipment are as follows: Pressing the start button causes the drive motor 51 to rotate, the rotating body 2 to rotate, and the transfer chamber to align with the frame channel on one side of the first sealing door 105. After the door is fully open, the drive motor 51 stops working, and the start indicator light illuminates. Pressing the stop button causes the drive motor 51 to rotate in the opposite direction. After the door is fully closed, the drive motor 51 stops working, and the stop indicator light illuminates. Pressing the stop button stops the drive motor 51. At this time, both the start and stop buttons are ineffective. The start and stop buttons can only be used after the stop button is released. Pressing the emergency stop button cuts off the power supply to the entire electrical control box.

[0082] In this embodiment, by setting up an electronic control system 7, the drive motor 51 can be controlled to work according to the position signal detected by the sensor 62, which can improve control flexibility, improve the automation level of the system, realize the cooperation between the position detection mechanism 6 and the drive mechanism, and facilitate intelligent management and control of the transfer equipment.

[0083] Specifically, the operation process of the transfer equipment is as follows: When items need to be transferred from the glove box to the hot chamber: First, place the items to be transferred from the glove box onto the transfer trolley 32, open the first sealing door 105, manually push the transfer trolley 32 into the transfer compartment of the rotating body 2, and close the first sealing door 105; start the drive mechanism through the electronic control system 7, drive the motor 51 to drive the coupling, transmission shaft 54, worm gear 52 and worm 53 and other components to rotate the rotating body 2 180 degrees, so that the transfer compartment corresponds to the frame channel on the side near the hot chamber, open the second sealing door 106, and move the transfer trolley 32 out of the transfer compartment.

[0084] When items need to be transferred from the hot chamber to the glove box: First, the second sealing door 106 is opened using a robotic arm. The items are placed on the transfer trolley 32 by the robotic arm. The second sealing door 106 is then closed. The drive mechanism is started through the electronic control system 7. The drive motor 51 drives the coupling, transmission shaft 54, worm gear 52, and worm 53 to run, causing the rotating body 2 to rotate 180 degrees in the opposite direction. The transfer chamber aligns with the frame channel on the side closest to the glove box. The first sealing door 105 is then opened, and the transfer trolley 32 is moved out of the transfer chamber.

[0085] Repeat the above process to complete the transfer of items between the hot chamber and the glove box.

[0086] Of course, in other alternative embodiments, the glove box may also be another radiation-free chamber adjacent to the hot chamber.

[0087] When items need to be transferred between hot chambers, the first sealing door 105 is opened using a robotic arm, and the items are placed on the transfer trolley 32 using the robotic arm. The second sealing door 106 is then closed. The drive mechanism is started through the electronic control system 7, and the drive motor 51 drives the coupling, transmission shaft 54, worm gear 52, and worm 53 to rotate, causing the rotating body 2 to rotate 180 degrees. The transfer chamber aligns with the frame channel on one side of the second sealing door 106. The second sealing door 106 is then opened, and the transfer trolley 32 is moved out of the transfer chamber. Correspondingly, the rotating body 2 can be rotated in the opposite direction to transfer the items in the hot chamber on the side of the second sealing door 106 to the hot chamber on the side of the first sealing door 105. The above process is repeated to complete the transfer of items between hot chambers.

[0088] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
