Abstract
Description
Technical Field
[0001] This invention relates to the field of transmission system technology, and in particular to a trolley cross-track motion system and method. Background Technology
[0002] In fields such as nuclear technology applications, radiotherapy, and industrial non-destructive testing, it is often necessary to transfer materials between lead rooms and other locations. The main function of a lead room is to effectively isolate radioactive radiation within the room through its thick lead shielding layer, thereby protecting the safety of personnel and the environment outside.
[0003] Due to the absolute requirements of radiation protection, the walls of the lead room must maintain complete shielding integrity. This means that no passage can be reserved in the walls for the track to pass through directly. As a result, the track inside the lead room cannot be directly connected to the track outside, forming a physical break. Consequently, the platform used to place materials on the track inside the lead room cannot be moved directly to the track outside for material transfer, causing inconvenience during material transfer. Summary of the Invention
[0004] The purpose of this invention is to provide a trolley cross-track movement system and method, which can move a material-carrying platform on the internal track of a lead room to the external track for material handover, making material handover more convenient.
[0005] To achieve the above objectives, in a first aspect, the present invention provides a trolley cross-track motion system, including an external track assembly, an internal track assembly, and a platform motion assembly; The internal track assembly is located on the side of the external track assembly; the platform motion assembly includes a main frame, multiple front V-shaped wheels, multiple rear V-shaped wheels, a platform, and a drive mechanism; the main frame is located on top of the internal track assembly; the multiple front V-shaped wheels are rotatably connected to the main frame and are located on both sides of the main frame; the multiple rear V-shaped wheels are rotatably connected to the main frame and are located on both sides of the main frame; the platform is fixedly connected to the main frame; the drive mechanism is located inside the main frame.
[0006] The external track assembly includes an external track, two external V-shaped guide rails, and an external rack; the external track is located on the side of the internal track assembly; the two external V-shaped guide rails are fixedly connected to the external track and are located on the top sides of the external track; the external rack is fixedly connected to the external track and is located inside the external track.
[0007] The internal track assembly includes an internal track, two internal V-shaped guide rails, and an internal rack. The internal track is located at the bottom of the main frame. The two internal V-shaped guide rails are fixedly connected to the internal track and are located on the top sides of the internal track, at the bottom of the multiple front V-shaped wheels and the multiple rear V-shaped wheels. The internal rack is fixedly connected to the internal track and is located inside the internal track.
[0008] The drive mechanism includes a support base, a motor, a driving bevel gear, a mounting base, a transmission shaft, a front gear, a middle gear, a rear gear, and a driven bevel gear. The support base is fixedly connected to the main frame and located inside the main frame. The motor is fixedly connected to the support base and located on the side of the support base. The driving bevel gear is fixedly connected to the output end of the motor and located on the side of the motor. The mounting base is fixedly connected to the main frame and located inside the main frame. The transmission shaft is rotatably connected to the mounting base and located on the side of the mounting base. The front gear is fixedly connected to the transmission shaft and located at the bottom of the transmission shaft, and the front gear meshes with the internal rack. The middle gear is rotatably connected to the mounting base and located at the bottom of the mounting base, and the middle gear meshes with the front gear. The rear gear is rotatably connected to the mounting base and located at the bottom of the mounting base, and the rear gear meshes with both the middle gear and the internal rack. The driven bevel gear is fixedly connected to the transmission shaft and located at the top of the transmission shaft, and the driven bevel gear meshes with the driving bevel gear.
[0009] The distance between the front V-shaped wheel and the rear V-shaped wheel is greater than the distance between the outer track and the inner track.
[0010] The size of the middle gear is smaller than that of the front gear and the rear gear.
[0011] Secondly, the present invention also provides a method for a trolley to move across a track, comprising: The drive mechanism is activated to move the platform along the internal track assembly. Driven by the drive mechanism, the stage moves from the internal track assembly to the external track assembly.
[0012] This invention discloses a trolley cross-track motion system and method. An internal track assembly is installed inside a lead-filled room, and an external track assembly is installed outside the lead-filled room. A platform is used to place materials. A driving mechanism drives the main frame and the platform to move along the internal track assembly. As the main frame and platform move, the main frame gradually moves onto the external track assembly, thereby moving the platform from inside the lead-filled room to the outside. This allows for material transfer or conveying. The front and rear V-shaped wheels facilitate smoother movement of the main frame. This method enables the platform, used for placing materials on the internal track assembly inside the lead-filled room, to be moved onto the external track assembly for material transfer, making the transfer more convenient and enabling precise positioning. Furthermore, the platform's moving assembly is small in size, adapting to the limited space inside the lead-filled room. Attached Figure Description

[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0024] In a first aspect, the present invention provides a trolley cross-track motion system, see [link to relevant documentation]. Figures 1-7 ,in, Figure 1 This is a schematic diagram of the overall structure of a trolley cross-track motion system according to the present invention; Figure 2 This is a schematic diagram of the external track assembly of the present invention; Figure 3 This is a schematic diagram of the internal track assembly of the present invention; Figure 4 This is a schematic diagram of the structure of the platform motion assembly of the present invention; Figure 5 This is a structural schematic diagram of the stage motion assembly of the present invention from another perspective; Figure 6 This is a cross-sectional view of the stage motion assembly of the present invention; Figure 7 This is an internal schematic diagram of the platform motion assembly of the present invention.
[0025] This invention provides a trolley cross-track motion system, including an external track assembly 1, an internal track assembly 2, and a platform motion assembly 3. The platform motion assembly 3 includes a main frame 4, multiple front V-shaped wheels 5, multiple rear V-shaped wheels 6, a platform 7, and a drive mechanism 8. The external track assembly 1 includes an external track 9, two external V-shaped guide rails 10, and an external rack 11. The internal track assembly 2 includes an internal track 12, two internal V-shaped guide rails 13, and an internal rack 14. The drive mechanism 8 includes a support base 15, a motor 16, a driving bevel gear 17, a mounting base 18, a transmission shaft 19, a front gear 20, a middle gear 21, a rear gear 22, and a driven bevel gear 23. Through the aforementioned solution, the platform 7, which is used to place materials on the internal track 12 of the lead room, can be moved to the external track 9 for material transfer, making material transfer more convenient.
[0026] In this specific embodiment, the internal track assembly 2 is located on the side of the external track assembly 1; the platform motion assembly 3 includes a main frame 4, multiple front V-shaped wheels 5, multiple rear V-shaped wheels 6, a platform 7, and a drive mechanism 8; the main frame 4 is located on top of the internal track assembly 2; the multiple front V-shaped wheels 5 are rotatably connected to the main frame 4 and are located on both sides of the main frame 4; the multiple rear V-shaped wheels 6 are rotatably connected to the main frame 4 and are located on both sides of the main frame 4; the platform 7 is fixedly connected to the main frame 4; and the drive mechanism 8 is disposed inside the main frame 4. The internal track assembly 2 is installed inside the lead room, and the external track assembly 1 is installed outside the lead room. The platform 7 is used to place materials. The main frame 4 and the platform 7 are driven by the drive mechanism 8 to move along the internal track assembly 2. As the main frame 4 and the platform 7 move, the main frame 4 will gradually move onto the external track assembly 1, thereby moving the platform 7 from inside the lead room to the outside, where material handover or transfer can then be carried out. The front V-shaped wheel 5 and the rear V-shaped wheel 6 make the movement of the main frame 4 smoother. In this way, the platform 7, which is used to place materials on the internal track assembly 2 inside the lead room, can be moved to the external track assembly 1 for material handover, making material handover more convenient and enabling precise positioning. At the same time, the platform movement assembly 3 is small in size and can adapt to the small space inside the lead room.
[0027] The outer track 9 is located on the side of the inner track assembly 2; two outer V-shaped guide rails 10 are fixedly connected to the outer track 9 and located on both sides of the top of the outer track 9; the outer rack 11 is fixedly connected to the outer track 9 and located inside the outer track 9. The outer V-shaped guide rail 10 is adapted to the front V-shaped wheel 5 and the rear V-shaped wheel 6, and the front V-shaped wheel 5 and the rear V-shaped wheel 6 move on the outer V-shaped guide rail 10 to guide the movement of the main frame 4 and the platform 7.
[0028] Secondly, the internal track 12 is located at the bottom of the main frame 4; two internal V-shaped guide rails 13 are fixedly connected to the internal track 12 and are located on the top sides of the internal track 12, and at the bottom of the multiple front V-shaped wheels 5 and the multiple rear V-shaped wheels 6; the internal rack 14 is fixedly connected to the internal track 12 and is located inside the internal track 12. The internal V-shaped guide rail 13 is adapted to the front V-shaped wheels 5 and the rear V-shaped wheels 6, and the front V-shaped wheels 5 and the rear V-shaped wheels 6 move on the internal V-shaped guide rail 13 to provide guidance for the movement of the main frame 4 and the platform 7.
[0029] Meanwhile, the support base 15 is fixedly connected to the main frame 4 and located inside the main frame 4; the motor 16 is fixedly connected to the support base 15 and located on the side of the support base 15; the drive bevel gear 17 is fixedly connected to the output end of the motor 16 and located on the side of the motor 16; the mounting base 18 is fixedly connected to the main frame 4 and located inside the main frame 4; the drive shaft 19 is rotatably connected to the mounting base 18 and located on the side of the mounting base 18; the front gear 20 is fixedly connected to the drive shaft 19 and located on the side of the drive shaft 18. At the bottom of shaft 19, the front gear 20 meshes with the internal rack 14; the middle gear 21 is rotatably connected to the mounting base 18 and located at the bottom of the mounting base 18, and the middle gear 21 meshes with the front gear 20; the rear gear 22 is rotatably connected to the mounting base 18 and located at the bottom of the mounting base 18, and the rear gear 22 meshes with the middle gear 21 and the internal rack 14 respectively; the driven bevel gear 23 is fixedly connected to the transmission shaft 19 and located at the top of the transmission shaft 19, and the driven bevel gear 23 meshes with the driving bevel gear 17. The distance between the outer rack 11 and the inner rack 14 is the gear number n × module; the motor 16 drives the driving bevel gear 17 to rotate, the driving bevel gear 17 drives the driven bevel gear 23 to rotate, the driven bevel gear 23 drives the front gear 20 to rotate via the transmission shaft 19, the front gear 20 drives the middle gear 21 and the rear gear 22 to rotate, and when moving on the internal track 12 inside the lead room, the front gear 20 and the rear gear 22 simultaneously mesh with the inner rack 14. When the movement passes through the gap between the inner track 12 and the outer track 9, the front gear 20 disengages from the inner rack 14, and the rear gear 22 engages with the inner rack 14 to drive it until the front gear 20 moves to the outer rack 11 on the outer track 9 for engagement. The rear gear 22 repeats this action until both the front gear 20 and the rear gear 22 are engaged with the outer rack 11, completing the movement. Reversing this movement, the platform movement assembly 3 returns to the lead room.
[0030] Furthermore, the distance between the front V-shaped wheel 5 and the rear V-shaped wheel 6 is greater than the distance between the outer track 9 and the inner track 12. This arrangement ensures that the platform 7 assembly does not vibrate when moving through the gap between the outer track 9 and the inner track 12. In this embodiment, four front V-shaped wheels 5 are provided, with two front V-shaped wheels 5 forming a group, and each group of front V-shaped wheels 5 is located on both sides of the front end of the main frame 4; four rear V-shaped wheels 6 are provided, with two rear V-shaped wheels 6 forming a group, and each group of rear V-shaped wheels 6 is located on both sides of the rear end of the main frame 4.
[0031] Finally, the size of the intermediate gear 21 is smaller than the size of the front gear 20 and the rear gear 22. The intermediate gear 21 is slightly smaller than the front gear 20 and the rear gear 22, and the intermediate gear 21 serves as the gear that transmits power to the front gear 20 and the rear gear 22.
[0032] In using this invention, the internal track 12 is installed inside the lead room, the external track 9 is installed outside the lead room, the platform 7 is used to place materials, the motor 16 drives the driving bevel gear 17 to rotate, the driving bevel gear 17 drives the driven bevel gear 23 to rotate, the driven bevel gear 23 drives the front gear 20 to rotate via the transmission shaft 19, and the front gear 20 drives the middle gear 21 and the rear gear 22 to rotate. When moving on the internal track 12 inside the lead room, the front gear 20 and the rear gear 22 simultaneously mesh with the internal rack 14 to move. When passing through the gap between the internal track 12 and the external track 9, the front gear 20 disengages from the internal rack 14, and the rear gear 22 meshes with the internal rack 14 to drive it until the front gear 20 disengages from the internal rack 14. The front gear 20 and the rear gear 22 engage with the external rack 11 on the external track 9, and the rear gear 22 repeats this action until both the front gear 20 and the rear gear 22 are engaged with the external rack 11, completing the movement; the reverse movement causes the platform movement assembly 3 to return to the lead room; when the platform 7 moves, the front V-shaped wheel 5 and the rear V-shaped wheel 6 roll on the internal track 12 and the external track 9, making the main frame 4 more stable when moving; in the above way, the platform 7, which is used to place materials on the internal track 12 inside the lead room, can be moved to the external track 9 for material transfer, making material transfer more convenient and enabling precise positioning. At the same time, the platform movement assembly 3 is small in size and can adapt to the small space inside the lead room.
[0033] Secondly, please refer to Figure 8 , Figure 8 This is a flowchart of a method for a trolley to move across a track according to the present invention. The present invention also provides a method for a trolley to move across a track, comprising: S1 opens the drive mechanism 8 to drive the stage 7 to move along the internal track assembly 2; The internal track assembly 2 is installed inside the lead room, the external track assembly 1 is installed outside the lead room, the platform 7 is used to place materials, and the main frame 4 and the platform 7 are driven to move along the internal track assembly 2 by the drive mechanism 8.
[0034] Driven by the drive mechanism 8, the S2 stage 7 moves from the inner track assembly 2 to the outer track assembly 1; As the main frame 4 and the platform 7 move, the main frame 4 will gradually move onto the external track assembly 1, thereby moving the platform 7 from inside the lead room to the outside, where material handover or transmission can then be carried out.
[0035] The present invention provides a method for trolley cross-track movement, which can move the material-carrying platform 7 on the internal track assembly 2 inside the lead room to the external track assembly 1 for material transfer, making material transfer more convenient and enabling precise positioning. At the same time, the material-carrying platform movement assembly 3 is small in size and can adapt to the small space inside the lead room.
[0036] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
