Abstract
Description
Technical Field
[0001] This invention relates to the field of aerospace technology, and more specifically to a space storage and transfer platform with a lead screw-driven wedge block pressing down. Background Technology
[0002] During the construction and operation of my country's space station, cargo spacecraft are a crucial component, transporting a large amount of supplies annually. Currently, cargo to the International Space Station is primarily transported via the Progress, H-II transfer spacecraft, Dragon, and Cygnus spacecraft. The methods of cargo transport are closely related to the spacecraft's structural form and overall mechanical properties, employing methods such as interference restraints, lashing restraints, and containerized long-distance transport. Packaged cargo is typically secured using panels and various numbers of crisscrossing lashing straps, all of which utilize lashing straps. However, this lashing installation method, performed on a frame-like structure, is unsuitable for installation within the honeycomb sandwich panel structure of cargo spacecraft.
[0003] The frame-structured fixed packages are stacked in three dimensions, which causes some problems for the transfer of packages. Although manual transfer can be effective and accurate, the transfer efficiency is low. When using a robotic arm for transfer, the three-dimensional stacked frame structure itself restricts the robotic arm's operating space, the robotic arm moves slowly, and the transfer efficiency is also low. The control system of the robotic arm is more complex, and the control accuracy is limited by the control system. Summary of the Invention
[0004] Therefore, the technical problem to be solved by the present invention is to overcome the problem that although manual transfer can be effective and accurate, the transfer efficiency is low, so as to provide a space storage and transfer platform with a screw-driven wedge block pressing down.

[0006] Furthermore, the cross-section of the wedge-shaped slider is a right-angled trapezoid.
[0007] Furthermore, the storage mechanism includes a first outer fixed side plate, a first inner fixed side plate, a second inner fixed side plate, a second outer fixed side plate, and a baffle plate arranged at intervals. The first outer fixed side plate, the first inner fixed side plate, the second inner fixed side plate, the second outer fixed side plate, and the baffle plate are all connected to the top plate. The lead screw pressing device is disposed on the first outer fixed side plate, the first inner fixed side plate, and the second inner fixed side plate.
[0008] Furthermore, the first outer fixing side plate, the first inner fixing side plate, the second inner fixing side plate, and the second outer fixing side plate are provided with a plurality of ball screws at intervals, which are used to fix the position of the cargo package.
[0009] Furthermore, the lead screw pressing device includes a lead screw mounting block and a rotating lead screw. The lead screw mounting block is located on the storage mechanism and connected to the top plate. The rotating lead screw is connected to the lead screw mounting block and the motor. The wedge block is disposed on the rotating lead screw.
[0010] Furthermore, the bottom platform includes a lower magnetic yoke, a transfer track, a frame, and a coil. The transfer track and frame are located on the lower magnetic yoke, and the coil is wound around the frame. The transfer track has multiple installation spaces for the coil inside, and the frame and coil array are grouped together and placed in the installation spaces.
[0011] Furthermore, the mover includes a mover frame, a cargo receiving plate, a universal ball, and a permanent magnet assembly. The cargo receiving plate is located on the mover frame, the universal ball is located at the bottom of the mover frame and abuts against the transfer track, and the permanent magnet assembly is located inside the mover frame and is located on the mover frame.
[0012] Furthermore, the cargo receiving plate is equipped with magnetic blocks.
[0013] Furthermore, the lower magnetic yoke is made of soft magnetic alloy 1J50 material.
[0014] Furthermore, the permanent magnet assembly is made of neodymium iron boron alloy hard magnetic material.
[0015] The technical solution of this invention has the following advantages:
[0016] The present invention provides a space storage and transfer platform with a screw-driven wedge block pressing mechanism, comprising: a storage device, the storage device including a top plate and a storage mechanism, and a screw pressing mechanism, the storage mechanism being disposed at the bottom of the top plate and used for storing cargo packages, and the screw pressing mechanism being disposed within the storage mechanism, the wedge block of the screw pressing mechanism being adapted to be inserted into the cargo package and connected to the cargo package; the wedge block including a screw mating block, a spring and a wedge slider, the wedge slider being slidably disposed in the groove of the screw mating block, one end of the spring being connected to the wedge slider and the other end being connected to the screw mating block; and a transfer platform including a bottom platform and a mover, the bottom platform being disposed at the bottom of the storage mechanism, the mover being disposed on the bottom platform, and the mover being used for transferring cargo packages.
[0017] By placing the storage mechanism at the bottom of the top plate, it can easily store packages of different sizes. Simultaneously, a screw-down device is installed within the storage mechanism. The wedge-shaped block of the screw-down device is inserted into the package, thus connecting the screw-down device to the package. The wedge-shaped slider is slidably positioned within the groove of the screw-fitting block, meaning it can slide within the screw-fitting frame. Because a spring is provided between the screw-fitting block and the wedge-shaped slider, they smoothly contact the package as the screw-down device pushes the slider down. The screw-down device then moves the package downwards, causing it to fall into the mover of the transfer platform. The transfer of the package is then achieved through the cooperation of the mover and the bottom platform.
[0018] This space storage and transfer platform, featuring a screw-driven wedge block pressing mechanism, offers better adaptability to the operating environment compared to existing package transfer methods. It boasts a high level of structural integration and modularity. The screw-driven wedge block pressing mechanism ensures precise transfer of packages. The wedge slider design guarantees that when the screw-driven wedge block rises, the spring retraction does not affect the transferred packages. The wedge slider and spring design ensure stable contact with the packages during pressing and avoid the impact of spring retraction on transfer, improving system reliability and lifespan. The coordinated design of the mover and bottom platform makes the transfer process more efficient and reduces transfer time.

[0038] The preferred embodiments of this disclosure are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.
[0039] Please see Figures 1 to 10 As shown, the present invention provides a space storage and transfer platform with a screw-driven wedge block 9 pressing down, comprising: a storage device, the storage device including a top plate 1 and a storage mechanism, a screw pressing device, the storage mechanism being disposed at the bottom of the top plate 1, the storage mechanism being used to store cargo packages 23, and the screw pressing device being disposed within the storage mechanism, the wedge block 9 of the screw pressing device being adapted to be inserted into the cargo package 23 and connected to the cargo package 23; the wedge block 9 including a screw mating block 18, a spring 19 and a wedge slider 20, the wedge slider 20 being slidably disposed in the groove of the screw mating block 18, one end of the spring 19 being connected to the wedge slider 20, and the other end being connected to the screw mating block 18; and a transfer platform including a bottom platform and a mover, the bottom platform being disposed at the bottom of the storage mechanism, the mover being disposed on the bottom platform, and the mover being used to transfer the cargo package 23.
[0040] By placing the storage mechanism at the bottom of the top plate 1, it is possible to store packages 23 of different sizes. Simultaneously, a screw-down device is installed within the storage mechanism, with its wedge-shaped block 9 inserted into the package 23, thus connecting the screw-down device to the package 23. The wedge-shaped slider 20 is slidably positioned within the groove of the screw-fitting block 18, allowing it to slide within the screw-fitting frame. Since a spring 19 is provided between the screw-fitting block 18 and the wedge-shaped slider 20, it smoothly contacts the package 23 during the downward pressing process of the screw-down device. The screw-down device then moves the package 23 downwards, causing it to fall into the moving part of the transfer platform. The transfer of the package 23 is achieved through the cooperation of the moving part and the bottom platform. During this process, any untransferred packages 23 are secured by the ball screws 21 on their respective storage mechanisms, thus enabling the transfer of individual packages 23.
[0041] This space storage and transfer platform, equipped with a screw-driven wedge block 9 for downward pressing, is better adapted to the working environment compared to existing cargo package 23 transfer methods. It features a high level of structural integration and modularity. The screw-driven wedge block 9 ensures precise transfer of the required cargo packages 23. The wedge slider 20 ensures that when the screw-driven wedge block 9 rises, the spring 19 retracts without affecting the cargo packages 23 being transferred. At the same time, it improves transfer efficiency.
[0042] In some optional embodiments, the cross-section of the wedge slider 20 is a right trapezoid. That is, the wedge slider 20 has an upper ramp structure and a lower flat structure; the upper ramp structure ensures that the retraction of the spring 19 when the lead screw drives the upward movement does not affect the transfer of the cargo package 23, and the lower flat structure ensures that a stable output force can be provided for downward pressure.
[0043] Specifically, the storage mechanism includes a first outer fixed side plate 2, a first inner fixed side plate 3, a second inner fixed side plate 4, a second outer fixed side plate 5, and a baffle 6 arranged at intervals. The first outer fixed side plate 2, the first inner fixed side plate 3, the second inner fixed side plate 4, the second outer fixed side plate 5, and the baffle 6 are all connected to the top plate 1. The lead screw pressing device is provided on the first outer fixed side plate, the first inner fixed side plate 3, and the second inner fixed side plate 4.
[0044] The first outer fixing side plate 2, the first inner fixing side plate 3, the second inner fixing side plate 4, the second outer fixing side plate 5, and the baffle 6 are all connected to the top plate 1, thus ensuring the stability of the connection between the first outer fixing side plate 2, the first inner fixing side plate 3, the second inner fixing side plate 4, the second outer fixing side plate 5, and the baffle 6 and the top plate 1. The first outer fixing side plate 2, the first inner fixing side plate 3, the second inner fixing side plate 4, and the second outer fixing side plate 5 together form three accommodating spaces. The cargo package 23 is set in the three accommodating spaces, and the size of the cargo package 23 in the three accommodating spaces can be the same or different. The cargo package 23 in each accommodating space has two rows. Of course, it can also be set to multiple rows, depending on the actual situation.
[0045] The baffle 6 is located at both ends of the first outer fixed side plate 2, the first inner fixed side plate 3, the second inner fixed side plate 4, and the second outer fixed side plate 5. It can work together with the first outer fixed side plate 2, the first inner fixed side plate 3, the second inner fixed side plate 4, and the second outer fixed side plate 5 to accommodate the cargo package 23 and prevent the cargo package 23 from moving.
[0046] The length of the baffle 6 is less than the lengths of the first outer fixed side plate 2, the first inner fixed side plate 3, the second inner fixed side plate 4, and the second outer fixed side plate 5, which means that transfer space needs to be reserved for the bottommost cargo package 23.
[0047] In some optional embodiments, a plurality of ball screws 21 are spaced apart on the first outer fixing side plate 2, the first inner fixing side plate 3, the second inner fixing side plate 4, and the second outer fixing side plate 5. The ball screws 21 are used to fix the position of the cargo package 23. That is, the ball screws 21 can be used to hold the cargo package 23 in place, so that the position of the cargo package 23 is fixed. When the cargo package 23 needs to fall onto the transfer platform, the lead screw pressing device can be used to press the cargo package 23 down, and the spring 19 of the ball screw 21 will contract, so that the lowest cargo package 23 falls onto the mover.
[0048] The lead screw pressing device includes a lead screw mounting block 7 and a rotating lead screw 8. The lead screw mounting block 7 is located on the storage mechanism and is connected to the top plate 1. The rotating lead screw 8 is connected to the lead screw mounting block 7 and the motor. The wedge block 9 is disposed on the rotating lead screw 8.
[0049] Specifically, the screw mounting block 7 provides an installation position for the rotating screw 8, and the rotating screw 8 is connected to the motor. The motor can provide power to the rotating screw 8, thereby driving the wedge block 9 to move up and down on the rotating screw 8, thus realizing the function of pressing down the cargo package 23.
[0050] The motor that provides the adsorption force can precisely achieve movement in both horizontal and vertical directions. The adsorption force ensures that it can adapt to the microgravity environment in space, while avoiding the mass and volume of additional mechanical transmission.
[0051] In this embodiment, the bottom platform includes a lower magnetic yoke 10, a transfer track 11, a frame 12, and a coil 13. The transfer track 11 and the frame 12 are disposed on the lower magnetic yoke 10, and the coil 13 is wound on the frame 12. The transfer track 11 has multiple installation spaces for the coil 13 inside, and the frame 12 and the coil 13 are arranged in an array and placed in the installation space.
[0052] The transfer track 11 and frame 12 are both fixed to the lower magnetic yoke 10 with screws to ensure the stability of the connection.
[0053] Specifically, the mover includes a mover frame 14, a cargo receiving plate 15, a universal ball 16, and a permanent magnet assembly 17. The cargo receiving plate 15 is disposed on the mover frame 14, the universal ball 16 is located at the bottom of the mover frame 14 and abuts against the transfer track 11, and the permanent magnet assembly 17 is located inside the mover frame 14 and disposed on the mover frame 14.
[0054] Among them, the cargo receiving plate 15 and the universal ball 16 are installed on the mover frame 14 by screws, the permanent magnet assembly 17 is arranged in an alternating array and installed on the mover frame 14 by screws, and the mover slides on the transfer track 11 through the bottom universal ball 16.
[0055] The cargo receiving plate 15 is U-shaped, so that the cargo package 23 is placed inside the cargo receiving plate 15 for transfer.
[0056] In actual use, the coil 13 in the transfer platform is energized, and in the permanent magnetic field generated by the lower yoke 10 and the permanent magnet assembly 17, a force in the X or Y direction is generated. The mover generates a permanent magnetic attraction force between the four sets of Halbach permanent magnet assemblies 17 and the coil 13. While passively and reliably adsorbing, it uses the driving force generated by the energized coil 13 to achieve two degrees of freedom translation.
[0057] Taking the force in the X direction as an example, the permanent magnet circuit in the gap is as follows: the magnetic flux starts from the N pole of the left vertical permanent magnet assembly 17, passes through the lower yoke 10, and returns to the S pole of the right vertical permanent magnet assembly 17. The left side of the middle horizontal permanent magnet assembly 17 is the N pole, passes through the lower yoke 10, and returns to the right S pole. The permanent magnet flux in the gap is the superposition of the magnetic flux of the vertical permanent magnet assembly 17 and the horizontal permanent magnet assembly 17. The permanent magnet circuit above is as follows: the magnetic flux starts from the N pole of the right vertical permanent magnet assembly 17, passes through the lower yoke 10, and returns to the S pole of the left vertical permanent magnet assembly 17. The left side of the middle horizontal permanent magnet assembly 17 is the N pole, passes through the lower yoke 10, and returns to the right S pole. The permanent magnet flux above is the difference between the magnetic flux of the vertical permanent magnet assembly 17 and the horizontal permanent magnet assembly 17. The diagonal permanent magnet assemblies 17 generate electromagnetic forces in the same direction. During movement, the corresponding coil 13 is energized according to the requirements of the direction of movement.
[0058] The magnetization direction of the permanent magnets in the permanent magnet assembly 17 from left to right is: top S, bottom N; left N, right S; top N, bottom S. Of course, the magnetization direction of the permanent magnets in the permanent magnet assembly 17 from left to right can also be: top N, bottom S; left S, right N; top S, bottom N. Specifically, it can be set according to the actual situation.
[0059] Magnetic blocks 22 can also be provided on the cargo receiving plate 15. The setting of magnetic blocks 22 facilitates the adsorption between the cargo receiving plate 15 and the cargo 23, thereby ensuring the stability of the cargo 23 during the transfer process and preventing the cargo 23 from moving.
[0060] The lower magnetic yoke 10 is made of soft magnetic alloy 1J50 material; the permanent magnet assembly 17 is made of neodymium iron boron alloy hard magnetic material.
[0061] The working principle of this space storage and transfer platform with a lead screw-driven wedge block 9 pressing down:
[0062] Each package 23 is locked by a set of ball screws 21 in the storage space, enabling daily storage of each package 23. Each row of storage space stores a package 23 of a certain size and type.
[0063] When a task requires the transfer of a certain type of cargo package 23, the corresponding lead screw pressing device is energized, the lead screw 8 rotates, and the wedge block 9 moves downward. The wedge block 9 engages with the groove on the side of the cargo package 23, pressing the cargo package 23 downward to overcome the locking force of the ball screw 21 and press it onto the mover of the transfer platform. The magnetic plate under the cargo package 23 is attracted by the magnetic block 22 on the mover, thus fixing the position of the cargo package 23 on the cargo package receiving plate 15. Then the lead screw 8 rotates in reverse, causing the wedge block 9 to move upward. The inclined surface of the wedge slider 20 is subjected to force, compressing the spring 19 until it is fully retracted. Therefore, the upward movement of the wedge block 9 will not affect the cargo package 23.
[0064] The permanent magnet component 17 in the mover and the lower yoke 10 generate an attraction force, ensuring that the mover is always above the transfer track 11. During horizontal transfer, the coil 13 at the bottom of the transfer platform is energized. Since the coil 13 is in the magnetic field formed by the upper yoke, the permanent magnet component 17 and the lower yoke 10 of the mover, an electromagnetic force is generated, which can drive the mover to move. Adjacent permanent magnet components 17 in the staggered array of permanent magnet components 17 generate a magnetic force perpendicular to the horizontal direction, and diagonal permanent magnet components 17 generate an electromagnetic force in the same direction. During movement, the corresponding coil 13 is energized according to the requirements of the direction of movement.
[0065] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
