This transfer box is a long rod transfer box for use in special occasions, with strict transfer requirements, including but not limited to gripping accuracy, transfer safety, and efficiency. Therefore, a matching transfer vehicle is needed for the transfer of this type of transfer box. This invention application proposes a transfer vehicle specifically for this transfer box based on this technical background. It is a special electromechanical device and also part of a matching or complete set of equipment. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a transfer box transfer device to solve the problems of equipment vibration and poor stability of existing wheeled forklifts during the transfer process in high-safety operation scenarios, and is applicable to situations where wheeled forklifts cannot be used.

[0004] The technical solution adopted by this invention to solve its technical problem is as follows:

[0005] A transfer box transport device includes an X-axis translation mechanism, a Y-axis telescopic fork mechanism, and a Z-axis lifting mechanism. The X-axis translation mechanism features an X-axis slide that moves horizontally along a ground rail foundation under the drive of a servo motor, transferring the transfer box to different workstations in a sealed state. The X-axis slide is mechanically equipped with a Z-axis lifting mechanism and a sealing cover. The sealing cover is open, and an automatic door assembly and a magnetic proximity switch are installed at the opening. When the transfer box to be transported approaches the magnetic proximity switch, the automatic door assembly opens and the Y-axis telescopic fork mechanism extends. The fork mechanism extends and grabs the transfer box. After grabbing, the automatic door assembly closes. During transportation, the transfer box is located in the sealed space formed by the automatic door assembly and the sealing cover. The Z-axis lifting mechanism includes a rigid column, a Z-axis support plate, and a second servo motor. The rigid column is fixed on the X-axis slide plate. A linear guide rail and a lead screw transmission assembly are installed between the Z-axis support plate and the rigid column and are driven by the second servo motor. The Y-axis telescopic fork mechanism is installed on the Z-axis support plate through a mounting bracket. After installation, the Y-axis telescopic fork mechanism is in a horizontal state.

[0006] Furthermore, the Y-axis telescopic fork mechanism includes a fixed guide assembly, a sliding arm, a third servo motor, a universal joint, a long shaft, and a quick-grip assembly. The sliding arm has a guide groove along its length and a rack structure. The fixed guide assembly is fixedly connected to a mounting bracket, and the sliding arm is slidably connected to the fixed guide assembly. The drive gear assembly is installed in the gap of the fixed guide assembly and meshes with the rack structure for transmission. The third servo motor is mechanically connected to the drive gear assembly via a coupling, universal joint, and long shaft, and drives the sliding arm to move mechanically along the Y-axis. The quick-grip assembly is installed at the front end of the sliding arm.

[0007] Furthermore, it also includes a cover plate, which is fixedly connected to the sliding arm.

[0008] Furthermore, it also includes a cover plate, the sliding arm and the cover plate are slidably connected by a second rolling bearing module, and the cover plate and the fixed guide assembly are mechanically connected as a whole by a steel clamp.

[0009] Furthermore, the rapid gripping assembly consists of a horizontal steel plate, a rigid sleeve, a compression spring, a guide sleeve, a pull rod, a docking plate, and a steel pin. The horizontal steel plate is mechanically connected to the sliding arm and / or the cover plate via a transition mounting plate. The guide sleeve and the rigid sleeve are fitted together, and a compression spring is installed in the guide sleeve. The pull rod passes through the compression spring and extends downward. The upper end of the pull rod is secured with a washer and a nut, and the lower end is fixedly connected to the docking plate. A steel pin is installed on the docking plate, and the steel pin is inserted into a pin hole in the transfer box for connection.

[0010] Furthermore, the automatic door assembly includes a fixed door panel, a movable door panel, an auxiliary motor, and a lead screw drive assembly. The movable door panel is a push-pull design and is driven by the auxiliary motor and the lead screw drive assembly. The sealing cover, the fixed door panel, and the movable door panel are made of aluminum sheet or lead sheet material.

[0011] Furthermore, the main body of the fixed guide assembly is formed by welding two strip steel plates and two mounting steel plates and has gaps. The gear assembly includes a drive gear, a driving gear and a transition gear. The gear shaft of the drive gear is connected to the long shaft through a coupling and a universal joint. The drive gear meshes with one of the driving gears for transmission. The driving gear and the transition gear mesh with each other.

[0012] Furthermore, a first rolling bearing module and a wear-resistant block are installed on the outer side of the strip steel plate in the fixed guide assembly. Both the first rolling bearing module and the wear-resistant block are slidably engaged with the pulley mounting groove in the sliding arm.

[0013] Furthermore, a limiting buffer module is installed between the fixed guide assembly and the sliding arm, which limits the extension length of the sliding arm.

[0014] Furthermore, the Z-axis support plate is a 3D structure formed by welding steel plates. The Z-axis support plate has a lead screw slider mounting point, an inclined support mounting point, and a mounting bracket mounting point, as well as a rib plate reinforcement design. A limit switch is installed on the rigid column. The limit switch controls the travel of the Z-axis support plate in the upper and lower positions. The high point of the travel is the maximum lifting height of the transfer box, and the low point is the lowest point of the transfer box release.

[0015] Furthermore, the mounting bracket includes a rectangular frame and a diagonal support, wherein the front end of the rectangular frame is fixedly connected to the Z-axis support plate and forms a rearwardly extending cantilever structure, and the diagonal support provides auxiliary support to the rectangular frame at the rear end of the cantilever structure.

[0016] Furthermore, the ground rail foundation consists of two parallel rails, with limiting blocks at both ends and multiple fixed angle brackets welded and fixed on the outside of the ground rail foundation. The X-axis slide and the ground rail foundation are connected by a linear guide rail assembly, a gear and rack assembly, and a servo motor.

[0017] Furthermore, a cable drag chain is installed between the aforementioned ground rail foundation and the X-axis slide.

[0018] Furthermore, the rectangular frame is composed of square steel and four mounting blocks, preferably welded together, with two mounting blocks fixedly connected to the diagonal support and two mounting blocks fixedly connected to the Z-axis support plate.

[0019] The beneficial effects of this invention are:

[0020] This equipment is driven by a combination of servo motor, lead screw drive, and linear guide rail, enabling it to operate in an ultra-quiet manner. Simultaneously, the buffer design of the fast-grabbing component filters out vibrations between the transfer box and the transfer vehicle, preventing vibrations from the transfer box and fundamentally solving the adverse effects on the transfer box. The advantages of this invention will be further elaborated in specific embodiments below. Attached Figure Description

Detailed Implementation

[0053] The applicant previously applied for an invention patent related to a transfer box, patent number CN202511194657.0. This transfer box is a specialized box, wherein the box structure includes a box shell, a door panel connected to the box shell, side positioners, and a mounting bracket. There are two side positioners, located on opposite sides of the box shell. In use, a forklift is first inserted into the side positioners on both sides of the transfer box, and then the position is adjusted by the forklift to transport the transfer box. The current problem is that ordinary forklifts exhibit vibration during the handling of this transfer box. Analysis shows that conventional fuel-powered wheeled forklifts vibrate and shake during handling, which is detrimental to the handling of rod-shaped parts and special materials in special situations. For example, such vibrations and shaking can be transmitted to the transfer container and cause safety hazards such as detachment or displacement of long rod parts inside the transfer container. For example, long rod parts in nuclear chemical industry need to be guaranteed to have zero vibration or basically no shaking during the transfer process and need to have radiation protection measures. The transfer equipment described in this embodiment is a special handling equipment for this type of transfer container and is also an important part of a set of supporting or complete equipment facilities.

[0054] Based on the special characteristics of the objects being processed and the stringent requirements of nuclear chemical sites, this invention proposes an implementable transfer container transfer device to improve the safety of nuclear chemical components during the transfer process.

[0055] Example 1, this Example 1 will be described in conjunction with the appendix to the instruction manual. Figure 1 To be continued Figure 29 This document details a transfer box transport device whose mechanical function is to grasp, transport, and release boxes, moving them from one workstation to another. The device includes an X-axis translation mechanism 100, a Y-axis telescopic fork mechanism 200, and a Z-axis lifting mechanism 300. All components are driven by servo motors and precision rotating parts to achieve vibration-free operation, making it a type of electromechanical equipment. It is also equipped with an automatic door assembly 500 and a sealing cover 400 to provide radiation protection for the transfer boxes and their internal parts, ensuring safety during transport and improving the protection level. The following section will provide a detailed explanation of the implementation process.

[0056] To facilitate description and understanding, an X, Y, Z coordinate system has been established for the accompanying drawings in the instruction manual, please refer to the legend.

[0057] The function of the X-axis translation mechanism 100 is to move horizontally along the guide rail and transport the transfer box to different workstations. The X-axis translation mechanism 100 is driven by a servo motor, featuring controllable and adjustable technical characteristics. Figure 2As shown, the mechanical structure of the X-axis translation mechanism 100 consists of a ground rail base 110, a gear and rack assembly 120, a linear guide rail assembly 130, a fixed angle bracket 140, an X-axis slide 150, and a servo motor 160. The ground rail base 110 is composed of two parallel rails mechanically connected at regular intervals by connecting steel plates or pipes. The two rails are parallel after connection, forming a frame structure. (Refer to...) Figure 2 and Figure 9 Multiple fixing brackets 140 are welded and fixed to the outside of the ground rail foundation 110, and bolt holes are provided in the fixing brackets 140 for fixing with anchor bolts. After fixing, the ground rail foundation 110 is completely fixed by the multiple fixing brackets 140, which can improve the stability during transportation. An X-axis slide plate 150 is slidably installed above the ground rail foundation 110 via linear guide rail assemblies 130, one on each side. Figure 9 . refer to Figure 11 and Figure 12 The X-axis slide 150 is a flat steel plate component, which is machined to form mounting points for other components. Figure 11 and Figure 12 The text includes descriptions of mounting points, such as linear guide mounting point 151, servo motor mounting point 152, Z-axis lifting mechanism mounting point 153, and sealing cover frame 410 mounting point. The X-axis slide 150 is used to mount functional components or assemblies such as the Z-axis lifting mechanism 300, sealing cover frame 410, sealing cover 400, and servo motor 160.

[0058] Furthermore, the X-axis slide 150 and the ground rail base 110 are connected by a linear guide rail assembly 130, a gear and rack assembly 120, and a servo motor 160. Specifically, the servo motor 160 is fixedly mounted on the X-axis slide 150, and a pinion gear on the motor shaft of the servo motor 160 meshes with a rack, forming a gear and rack transmission. The driving force comes from the servo motor 160. Smooth movement along the X-axis is achieved through the linear guide rail assembly 130, the gear and rack assembly 120, and the servo motor 160. This design, through the cooperation of the linear guide rail 130, the gear and rack transmission, and the servo motor, provides ultra-quiet drive for the X-axis slide 150, reducing vibration at its source.

[0059] Further, refer to Figure 9 Limiting blocks 111 are provided at both ends of the ground rail foundation 110. The limiting blocks 111 are fixed to the ends of the ground rail foundation 110 by high-strength bolts to limit the movement of the X-axis slide plate 150 and prevent the X-axis slide plate 150 from falling off.

[0060] Furthermore, the aforementioned ground track foundation 110 can be either a straight track or a curved track.

[0061] Furthermore, a cable drag chain 170 is installed between the aforementioned ground rail foundation 110 and the X-axis slide 150. The cable drag chain 170 is used to arrange electrical cables such as cables and signal lines. This is a standard configuration and will not be described in detail.

[0062] Furthermore, a sealing cover frame 410 with a three-dimensional structure is mechanically fixedly installed on the periphery of the X-axis slide 150. The sealing cover frame 410 is also the frame of the sealing cover 400, used to install and fix the sealing cover 400. The sealing cover 400 is made of metal plate. Through the enclosure of the sealing cover 400 and the frame, the installation and mechanical operation space of the Y-axis telescopic fork mechanism 200 and the Z-axis lifting mechanism 300 are formed above the X-axis slide 150, which is also the storage center of the transfer box.

[0063] Furthermore, the metal sheet used in the sealing cover 400 is preferably made of materials with excellent radiation protection performance, such as aluminum sheet or lead sheet, and is subjected to sheet metal shaping as needed, such as local shape design.

[0064] Furthermore, the front side of the aforementioned sealing cover 400 is designed as an open opening, and the automatic door assembly 500 is located at this opening, which also serves as the inlet and outlet for transporting the transfer box. (Reference) Figure 1 and Figure 7 The automatic door assembly 500 is implemented through the following electromechanical structure: The automatic door assembly 500 includes a fixed door panel (covered by a movable door panel 510 in the figure), a movable door panel 510, an upper slide rail, a lower slide rail, an auxiliary motor 520, and a lead screw drive assembly 530. The fixed door panel is fixedly installed, while the movable door panel 510 is movably mounted on the upper and lower slide rails using upper and lower pulleys. After installation, the movable door panel 510 moves to open and close the door. In the open state, the movable door panel 510 overlaps with the fixed door panel; in the closed state, the movable door panel 510 is closed. Figure 1 The image shows the open state. In this embodiment, the movement of the movable door panel 510 is achieved through the following structure: the movable door panel 510 and the upper slide rail are driven by a lead screw drive assembly 530, wherein the lead screw is mechanically connected to the auxiliary motor 520 via a coupling, and the lead screw sleeve is installed on the movable door panel 510, that is, the movable door panel 510 is driven to open and close by the auxiliary motor 520.

[0065] The operation of the automatic door assembly 500 is as follows: A magnetic proximity switch (not shown in the figure) is installed near the door frame of the automatic door assembly 500. This magnetic proximity switch faces the direction of the object to be transported. When the transfer box (not shown in the figure) approaches this magnetic proximity switch, the auxiliary motor 520 starts and drives the movable door panel 510 to open. The Y-axis telescopic fork mechanism 200 extends and grabs the transfer box (not shown in the figure). (Refer to...) Figure 5 After grabbing, the Y-axis telescopic fork mechanism 200 retracts. The use of this automatic door assembly 500 provides secondary radiation protection for the internal transfer box, improving safety during the transfer process.

[0066] Furthermore, the aforementioned fixed door panels and movable door panels 510 also use materials such as aluminum sheet and lead sheet.

[0067] The Z-axis lifting mechanism 300 in this embodiment includes a rigid column 310, a Z-axis support plate 320, a linear guide rail 330, a lead screw transmission assembly 340, and a second servo motor 350. The rigid column 310 is formed by welding six thick steel plates (top, bottom, left, right, front, and back). This structure has a larger cross-section and greater rigidity. Bolt holes are provided on the base plate of the rigid column 310. (Refer to...) Figure 13 The rigid column 310 is fixed to the X-axis slide plate 150 by high-strength bolts. After fixing, the rigid column 310 is in a vertical state and perpendicular to the X-axis slide plate 150. The rigid column 310 provides installation support and load.

[0068] Furthermore, the aforementioned rigid column 310 is a hollow structure. Servo motor mounting point 152, linear guide rail mounting point 151, and lead screw mounting point are provided on the front side of the rigid column 310. A Z-axis support plate 320 is installed on the front side of the rigid column 310. Specifically, a linear guide rail 330 and a lead screw transmission assembly 340 are installed between the Z-axis support plate 320 and the rigid column 310. The position of the Z-axis support plate 320 is adjusted by the driving action of the linear guide rail 330, the lead screw transmission assembly 340, and the second servo motor 350, thus achieving height adjustment of the Z-axis support plate 320 and achieving height-direction lifting.

[0069] Furthermore, a limit switch (not shown in the figure) is installed on the aforementioned rigid column 310. This limit switch is used to control the vertical travel of the Z-axis support plate 320. The highest point of this travel is the maximum lifting height of the transfer box, and the lowest point is the lowest point of the transfer box release.

[0070] Furthermore, the detailed structure of the Z-axis support plate 320 is as follows: The Z-axis support plate 320 is a 3D structure welded from steel plates. Its back side has a lead screw / slider mounting point and a diagonal support 620 mounting point, its top has a mounting bracket 600 mounting point, and its front side has ribs. This Z-axis support plate 320 has sufficient rigidity to meet the mechanical requirements for installation and torsional resistance. The Y-axis telescopic fork mechanism 200 is mounted on the Z-axis support plate 320 via the mounting bracket 600 and secured with bolts. After installation, the Y-axis telescopic fork mechanism 200 is in a horizontal state to achieve the function of horizontal telescopic extension. Mechanically, this mechanism includes a fixed guide assembly 210, a sliding arm 220, a cover plate 230, a third servo motor 240, a universal joint 250, a long shaft 260, and a quick-grip assembly 270.

[0071] Furthermore, the aforementioned mounting bracket 600 includes a rectangular frame 610 and a diagonal support 620. The front end of the rectangular frame 610 is fixedly connected to the aforementioned Z-axis support plate 320, forming a rearwardly extending cantilever structure. At the same time, the diagonal support 620 provides auxiliary support to the rear end of the rectangular frame 610 of the cantilever structure. Specifically, the upper end of the diagonal support 620 is fixedly installed at the rear end of the rectangular frame 610, and the lower end of the diagonal support 620 is fixedly installed at the diagonal support 620 mounting point on the back of the Z-axis support plate 320, forming an auxiliary support to improve the stability of the rectangular frame 610 and give the device sufficient rigidity.

[0072] Furthermore, the rectangular frame 610 is composed of square steel and four mounting blocks, preferably welded together, with two mounting blocks fixedly connected to the diagonal support 620 and two mounting blocks fixedly connected to the Z-axis support plate 320.

[0073] Furthermore, the third servo motor 240 is directly or fixedly mounted on the aforementioned rectangular frame 610 via a motor mounting bracket, and connected to the long shaft 260 via a coupling and universal joint 250, forming two synchronous drive structures. Specifically, the third servo motor 240 synchronously drives the two drive gears 281. In this embodiment, the aforementioned drive gear assembly 280 is mounted in the fixed guide assembly 210, i.e., rotatably connected via bearings. There are two fixed guide assemblies 210. (Reference) Figures 20 to 22The fixed guide assembly 210 is mainly formed by welding two strip steel plates 211 and two mounting steel plates 212, and has a narrow gap 215. The fixed guide assembly 210 provides support for extension and retraction. A drive gear 281, three active gears 282, and two transition gears 283 are installed within the gap 215. The gear shaft of the drive gear 281 is connected to the long shaft 260 via a coupling and a universal joint 250. The drive gear 281 meshes with one of the active gears 282, while the remaining active gears 282 and transition gears 283 mesh with each other. After meshing, the rotation of the drive gear assembly 280 drives the three active gears 282 to rotate in the same direction and synchronously. The active gears 282 mesh with the rack structure 223 in the sliding arm 220, realizing the function of pushing the sliding arm 220 out. The push and retraction are driven by a rack and pinion mechanism and a servo motor, resulting in good quietness and minimal vibration, which will be described in detail below. In this embodiment, the two strip steel plates 211 are fixed by mounting steel plates 212 welded at both ends. Bolt holes are provided on the mounting steel plates 212, and the front end of the fixed guide assembly 210 is fixed to the mounting bracket 600 by bolts. A transition mounting block 630 positioned between the two is used for leveling. In improved designs, the transition mounting block 630 can be omitted, all within the scope of this invention. Simultaneously, the rear end of the fixed guide assembly 210 is further supported by bolts to the inclined support 620. This connection method ensures the fixed guide assembly 210 is securely fixed, guaranteeing stability during transport.

[0074] Furthermore, a first rolling bearing module 213 is installed on the outside of the two strip steel plates 211 of the fixed guide assembly 210. The first rolling bearing module 213 is used to slide with the pulley mounting groove 222 in the sliding arm 220. That is, the sliding arm 220 is provided with a pulley mounting groove 222 arranged along the length direction. This design enables the sliding arm 220 and the fixed guide assembly 210 to form a rolling fit, resulting in ultra-quiet operation.

[0075] Furthermore, an oil-impregnated copper block or a self-lubricating lead block 216 is installed on the outside of the two strip steel plates 211. It is set in the space between the two first rolling bearing modules 213. The side of the self-lubricating lead block 216 slides with the side of the sliding arm 220 to avoid excessive gap between the sliding arm 220 and the strip steel plate 211, solve the wobbling problem that may occur during the movement of the sliding arm 220, and improve the smoothness of the movement of the sliding arm 220.

[0076] Furthermore, a limiting buffer module 214 is installed between the outer side of the strip steel plate 211 and the sliding arm 220. The protruding length of the sliding arm 220 is limited by the limiting buffer module 214, that is, it provides limiting and buffering in the sliding direction. The limiting buffer module 214 can be a rubber block, hydraulic buffer, etc.

[0077] refer to Figures 23 to 25 The sliding arm 220 is a long strip structure with a narrow guide groove 221 extending along its length. A raised rack structure 223 is provided within the guide groove 221. The rack structure 223 has a certain length and is used to cooperate with the drive gear 282. That is, the drive gear 282 drives the rack structure 223 to achieve the extension and retraction of the sliding arm 220. The guide groove 221 extends through the length of the sliding arm 220, and concave pulley mounting grooves 222 are provided on both sides of the guide groove 221. The pulley mounting grooves 222 slide in cooperation with the first rolling bearing module 213 and the oil-impregnated copper block on the outer side of the strip steel plate 211, with a relatively small gap, improving the stability during the extension and retraction process. Meanwhile, pulley mounting grooves 222 are provided on the outer side walls of the sliding arm 220. These grooves are used for sliding engagement with the second rolling bearing modules 231 on the cover plate 230. The cover plate 230 is fixedly mounted on the sliding arm 220, and the second rolling bearing modules 231 are provided on both sides of the inner wall of the cover plate 230. Multiple screws 232 are used to secure the cover plate 230 and the sliding arm 220 together. This method achieves reliable fixation between the cover plate 230 and the sliding arm 220, ensuring that the cover plate 230 is securely fixed to the sliding arm 220 and slides effectively with it.

[0078] Furthermore, in this embodiment, the design of the cover plate 230 facilitates maintenance; simply remove the screws 232 between the cover plate 230 and the sliding arm 220, and pull the cover plate 230 out horizontally. Simultaneously, the cover plate 230 has a U-shaped cross-section, which protects and prevents dust from the sliding telescopic structure below, improving the safety performance of the equipment. Figure 26 A specific embodiment is shown in detail.

[0079] Figure 29A specific quick-grip assembly 270 is shown, which consists of a horizontal steel plate 271, a rigid sleeve 272, a compression spring 273, a guide sleeve 274, a pull rod 275, a docking plate 276, and a steel pin 277. The horizontal steel plate 271 is fixedly installed to the cover plate 230 via a transition mounting plate 290. The transition mounting plate 290 and the quick-grip assembly 270 move with the sliding arm 220. The rigid sleeve 272 is a circular or square steel cylinder welded to the front end of the horizontal steel plate 271, with reinforcing ribs welded at the connection area to improve connection strength. The rigid sleeve 272 has a base, and a compression spring 273 is placed inside the rigid sleeve 272. This compression spring 273 can filter out vibrations of the equipment, reducing the adverse effects of vibration on the transfer box. A pull rod 275 passes through the center of the compression spring 273 and extends downwards. A round or square washer and nut are used to secure the upper end of the pull rod 275, while a mating plate 276 is fixedly connected to the lower end. This mating plate 276 is a thick steel plate used for quick-connection with the lateral locator in the transport box. The mating plate 276 is flat and has a steel pin 277 installed on its top. The rear end of the mating plate 276 is connected to the pull rod 275 and secured with a nut. A guide sleeve 274 is welded and fixed to the mating plate 276. The guide sleeve 274 extends upwards and fits over the rigid sleeve 272. The cooperation between the guide sleeve 274 and the rigid sleeve 272 allows for relative sliding only in the height direction, thus improving the strength of the structure. In this structural design, after the transfer box is grasped, the aforementioned steel pin 277 is inserted into the pin hole of the lateral locator (refer to the applicant's prior application CN202511194657.0), and is inserted from bottom to top to lock the transfer box. The compression spring 273 in this embodiment has a certain buffering performance. By selecting a compression spring 273 with appropriate stiffness, harmful vibrations during the handling process can be effectively filtered out, which has a protective effect on the transfer parts inside the transfer box.

[0080] Furthermore, the compression spring 273 in this embodiment is a buffer element. Similar alternatives include rubber pads, rubber blocks, airbags, etc., all of which should fall within the protection scope of this invention.

[0081] The Y-axis telescopic fork mechanism 200 drives two sliding arms 220 to telescopically move in the Y-axis direction via a No. 3 servo motor 240, and pushes out the quick-grip component 270 located at the top of the sliding arm 220 to achieve movement in the Y-axis direction. The quick-grip component 270 itself has the function of buffering and filtering vibration, which is of positive significance for improving safety during the handling process.

[0082] A complete working process of this equipment is as follows:

[0083] The operating trajectory of this equipment includes a three-coordinate space system of X / Y / Z. In the X direction, the X-axis slide 150 is driven by the No. 1 servo motor 160 to move along the linear guide rail 330, so that the fork assembly on the transfer vehicle can move along the X-axis to realize the transfer between different workstations.

[0084] In the Y direction, the Y-axis telescopic fork mechanism 200 extends and retracts in the front-to-back direction to move the transfer box to the inside or outside of the sealing cover 400.

[0085] In the Z direction, the height of the transfer box is raised or lowered by the second servo motor 350.

[0086] Through close coordination in these three directions, the transfer container can be grasped, transported, and released. The stability of the entire process is significantly improved compared to traditional wheeled forklifts, ensuring the safety of the handling process. This has positive safety implications for nuclear industry production.

[0087] Example 2, reference Figure 30 This second embodiment details another structural evolution. The horizontal steel plate 271 is mechanically connected to the sliding arm 220 via a transition mounting plate 290. That is, the fixedly installed transition mounting plate 290 and the quick-grip assembly 270 move with the movement of the sliding arm 220. Simultaneously, the cover plate 230 is shortened and avoids the installation location of the transition mounting plate 290. Based on the first embodiment, steel clamps 700 are used to fix the cover plate 230 and the two strip steel plates 211 of the fixed guide assembly 210. Specifically, a pair of steel clamps 700 are installed between them, and the steel clamps 700 are fixed to the strip steel plates 211 and the cover plate 230 with fastening screws. After fixing, a stable fixed relationship is formed between the strip steel plates 211 and the cover plate 230, preventing wobbling between them. Through this embodiment, the sliding arm 220 can slide and extend in the gap space between the fixed guide assembly 210 and the cover plate 230 to form a telescopic structure with adjustable length. In this embodiment, the cover plate 230 strengthens the constraint on the sliding arm 220 and improves its rigidity during the sliding process. The implementation of this second embodiment significantly enhances the torque of the sliding arm 220 during the extension and retraction process and improves the overall stability of the transfer equipment.

[0088] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements to the present invention by those skilled in the art should fall within the protection scope defined by the claims of the present invention.
