Description

Technical Field

[0001] The present invention relates to the technical field of space structure mechanisms, and particularly to a double - helix dense storage and transfer device. Background Art

[0002] In the process of space exploration and development, the construction of large - scale space facilities is a crucial link, such as the expansion of space stations, the construction of lunar bases, and the possible construction of Mars bases in the future. The construction of these large - scale facilities requires the support of a large amount of materials, including building materials, equipment, life supplies, etc.

[0003] Due to the high cost of space transportation and the limited amount of materials that can be carried per transportation, in the Earth's orbit and deeper space environments, space resources are extremely precious, and the requirement for storage efficiency is extremely high. If efficient storage cannot be achieved, it will lead to frequent transportation requirements, greatly increasing costs and project cycles. However, traditional storage methods mainly rely on simple in - cabin stacking or storage units arranged in a single dimension. When faced with the storage requirements of a large amount of materials, there are often problems of low space utilization rate. In addition, in a microgravity environment, it is also difficult to fix and manage materials. Traditional storage methods are prone to cause displacement, collision, and even damage of materials during spacecraft attitude adjustment or other operations, thus affecting the smooth progress of the entire facility construction task.

[0004] At the same time, as the scale of space exploration projects continues to expand, the construction period also increases. Therefore, during long - term space storage, extreme environmental factors such as space radiation, temperature changes, and micrometeorite impacts also have a certain impact on stored materials. Existing storage technologies usually do not have means to protect against these adverse factors and are difficult to ensure that materials can still maintain their performance and integrity after long - term storage to meet the requirements of large - scale space facility construction.

[0005] In ground warehousing technology, there are various technical solutions for efficient storage and transfer. For example, by using shelf modules, handling modules, storage management modules, etc., through intelligent management and control, efficient storage and handling of goods in a three - dimensional warehouse are achieved, improving space utilization rate and storage efficiency; through unique shelf structures and conveying devices, the vertical space of the warehouse is fully utilized, increasing storage density, and at the same time facilitating the access and management of goods; by using shuttle - type dense storage shelves, the rapid access of goods is realized through the operation of shuttle cars on the shelf tracks, improving the space utilization rate of the shelves; and by using push - back dense storage shelves, goods are arranged more closely during storage, reducing the aisle space between shelves and increasing storage density. However, these technical means are difficult to be applied to space transportation and storage. Summary of the Invention

[0006] In view of some or all of the problems in the prior art, the present invention provides a double - helix dense storage and transfer device, comprising:

[0007] A spiral slide rail shaft, on the surface of which a spiral slide rail is provided, and the spiral slide rail shaft can rotate around its axis;

[0008] A chute sleeve, which is sleeved outside the spiral slide rail shaft and rotates relative to the spiral slide rail shaft around the same axis, and a plurality of chutes are arranged on the chute sleeve along the axial direction; and

[0009] A plurality of brackets, which are connected to the spiral slide rail shaft in a double - helix staggered form, and the brackets are used to fix materials.

[0010] Further, the double - helix dense storage and transfer device further comprises a planetary gearbox. The sun gear of the planetary gearbox is connected to the second end of the spiral slide rail shaft, and the planetary gear pair is connected to the second end of the chute sleeve. The planetary gearbox is used to provide a speed difference between the spiral slide rail shaft and the chute sleeve.

[0011] Further, the number of teeth of the sun gear and the ring gear of the planetary gearbox is determined according to the pitch of the spiral line of the required material flow.

[0012] Further, the first end of the chute sleeve opposite to its second end is connected to the spiral slide rail shaft through a bearing. The inner ring of the bearing is sleeved on the spiral slide rail shaft, and the chute sleeve is sleeved on the outer ring of the bearing.

[0013] Further, the speed ratio between the chute sleeve and the spiral slide rail shaft is determined according to the pitch of the spiral line of the required material flow.

[0014] Further, the pitch of the spiral line of the required material flow is equal to the pitch of the spiral slide rail shaft multiplied by the result of dividing the speed difference between the chute sleeve and the spiral slide rail shaft by the speed of the chute sleeve.

[0015] Further, the double - helix dense storage and transfer device further comprises a housing. Two discharge ports are arranged at the first end of the side wall of the housing, where the first end refers to the end far from the planetary gearbox.

[0016] Further, the two discharge ports are arranged oppositely.

[0017] Further, the double - helix dense storage and transfer device further comprises a bracket storage compartment, which is arranged at the first end of the housing and is used for recycling the brackets.

[0018] Further, the first end of the bracket includes a slider, and the slider is embedded in the spiral slide rail of the spiral slide rail shaft.

[0019] Further, the second end of the bracket opposite to its first end includes an automatic unlocking module, which is used to fix the materials and automatically unlock them at the shipping outlet.

[0020] A double - helix dense storage and transfer device provided by the present invention realizes high - density storage and transfer of materials through the combination of double - helix high - density stacking storage, a synchronous drive shaft, and a guide rail sleeve. Among them, the staggered stacking design can be used for fixing and locking materials, establishing a high - stiffness connection, which is beneficial to meeting the requirements of anti - overload and fundamental frequency during the launch and powered flight stages.

It should be noted that the components in the drawings may be exaggerated for illustration purposes and not necessarily to the correct scale. In the drawings, the same or functionally identical components are provided with the same reference numerals.

[0031] In the present invention, unless otherwise specified, the quantifiers "a" and "one" do not exclude the scenario of multiple elements.

[0032] It should also be noted here that in the embodiments of the present invention, for the sake of clarity and simplicity, only a part of the components or assemblies may be shown. However, those of ordinary skill in the art can understand that, under the teaching of the present invention, the required components or assemblies can be added according to the specific scenario requirements.

[0033] It should also be noted here that within the scope of the present invention, the terms "identical", "equal", "equivalent", etc. do not mean that the two values are absolutely equal, but allow a certain reasonable error. That is to say, the above terms also cover "substantially identical", "substantially equal", "substantially equivalent". By analogy, in the present invention, the directional terms "perpendicular to", "parallel to", etc. also cover the meanings of "substantially perpendicular to" and "substantially parallel to".

[0034] In order to meet the large storage requirements of plate-shaped materials such as parabolic antennas during the process of constructing large in-orbit facilities in space, the present invention provides a double-helix dense storage and transfer device. Through the double-helix dense stacking and transfer technology, it realizes the high-density storage of materials, while meeting the requirements of material transfer, and further realizes high space utilization rate, specialized storage and retrieval. Specifically, the plate-shaped materials are stored in an interleaved arrangement along a double-helix trajectory, with high space utilization rate without interference. At the same time, the interleaved part can be used to establish the connection between two earth-facing loads to improve the overall anti-shock ability and fundamental frequency. The materials can be driven by the spiral slide rail shaft and the chute sleeve to move along the double-helix trajectory. The spiral slide rail shaft and the chute sleeve are connected by planetary gears to achieve linkage, and ensure that the materials move on the set double-helix curve, so that the materials can be transported to two outlets at the same end for easy retrieval by the demand side.

[0035] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings of the embodiments.

[0036] Figure 1 The structural schematic diagram of a double-helix dense storage and transfer device showing an embodiment of the present invention is as followsFigure 1 As shown, a double-helix intensive storage and circulation device includes a shell 101, the top of the side wall of the shell 101 is provided with two opposite delivery ports 111, and the top of the shell 101 is provided with a bracket storage compartment 102, and the bracket storage compartment is used to recover the brackets whose materials have been taken away. The interior of the shell 101 is used as a storage compartment for the storage and circulation of materials 001. The materials 001 are stored in the storage compartment, specifically, they are fixed on the various brackets 103 inside the shell 101. Figure 1 As shown, the bracket 103 is connected to the driving shaft 104 at the center of the double-helix intensive storage and circulation device. A planetary gear box 105 is arranged at the bottom of the driving shaft 104, and the planetary gear box 105 is used to drive the driving shaft 104 to rotate.

[0037] Figure 2 The internal structure schematic diagram of a double-helix dense storage and circulation device according to one embodiment of the present invention is shown. Figure 2 As shown, the main structure of the double-helix dense storage circulation device includes a drive shaft 104 and a bracket 103. In one embodiment of the present invention, in order to improve space utilization and achieve high-density storage, each bracket 103 is staggeredly connected to the drive shaft 104 in the form of a double helix, and any bracket 103 can spirally rise around the axis of the drive shaft 104 to the delivery port 111. The staggered arrangement in the form of a double helix has a high space utilization rate without interference, and the staggered part can be used to establish a connection between two plate-like materials to improve the overall impact resistance and base frequency. The double-helix dense storage circulation device can be expanded along the axial direction to meet the storage requirements of a larger amount of plate-like materials.

[0038] Figure 3 The following is a schematic diagram of the exploded view of the drive shaft and the support of a double-helix dense storage and circulation device according to one embodiment of the present invention. Figure 3 As shown, the drive shaft includes a spiral guide shaft 301 and a slide sleeve 302. The slide sleeve 302 is sleeved on the outside of the spiral guide shaft 301 and rotates relative to the spiral guide shaft 301 around the same axis. In one embodiment of the present invention, the first end of the slide sleeve 302 is connected to the spiral guide shaft 301 through a bearing, the inner ring of the bearing is sleeved on the spiral guide shaft 301, and the slide sleeve 302 is sleeved on the outer ring of the bearing.

[0039] In an embodiment of the present invention, there is a rotational speed difference between the chute sleeve 302 and the spiral slide rail shaft 301, and the rotational speed difference is provided by the planetary gearbox 105. Specifically, the sun gear of the planetary gearbox 105 is connected to the second end of the spiral slide rail shaft 301, and the planetary gear pair is connected to the second end of the chute sleeve 302, thereby providing the rotational speed difference between the spiral slide rail shaft and the chute sleeve. In an embodiment of the present invention, the number of teeth of the sun gear and the ring gear can be adjusted according to the helix pitch required for material storage, so as to change the transmission ratio between the chute sleeve 302 and the spiral slide rail shaft 301, and further enable the material to move on the expected spiral line. In an embodiment of the present invention, the speed ratio between the chute sleeve 302 and the spiral slide rail shaft 301 can be determined according to the stacking condition of the materials, that is, the helix pitch of the material flow. Specifically, the rotational speed difference between the chute sleeve 302 and the spiral slide rail shaft 301 is divided by the rotational speed of the chute sleeve 302, and then multiplied by the pitch of the spiral slide rail shaft 301, which should be equal to the helix pitch of the spiral line of the material movement. When the chute sleeve 302 and the spiral slide rail shaft 301 rotate in the same direction, the rotational speed difference is equal to the difference between the rotational speeds of the two. When the chute sleeve 302 and the spiral slide rail shaft 301 rotate in opposite directions, the rotational speed difference is equal to the sum of the rotational speeds of the two.

[0040] Figure 4 The partial cross-sectional schematic diagram of the spiral slide rail shaft of a double-spiral dense storage and transfer device showing an embodiment of the present invention is as Figure 3 and Figure 4 shown, a spiral-shaped slide rail is provided on the surface of the spiral slide rail shaft 301, and then the bracket 103 is connected to the spiral slide rail shaft 301 and can move spirally along the slide rail. As Figure 3 shown, a plurality of chutes 321 are provided on the chute sleeve 302 along the axial direction. After the first end of the bracket 103 passes through the chutes 321, it is embedded in the slide rail of the spiral slide rail shaft 301 and slides along the slide rail.

[0041] Figure 5 The structural schematic diagram of the bracket of a double-spiral dense storage and transfer device showing an embodiment of the present invention is as Figure 5 shown, in an embodiment of the present invention, the first end of the bracket includes a slider 501, and the slider 501 can be embedded in the spiral slide rail of the spiral slide rail shaft 301. The second end of the bracket opposite to its first end includes an automatic unlocking module 502, and the automatic unlocking module 502 is connected to the material and establishes a stable connection with the material during the storage stage. When it gradually rotates to the shipping outlet 111 as the material is taken out, it is unlocked by the automatic lock unlocking auxiliary mechanism at the shipping outlet 111, and the bracket 103 is separated from the material 001.

[0042] Based on this, the materials can flow within the storage bin. Specifically, the support 103 passes through the chute sleeve 302, so it is restricted to slide along the spiral slide rail, and finally the support 103 drives the materials to move along a double - helix path to the delivery port 111. When it moves to the delivery port 111, the automatic unlocking module 502 automatically unlocks, and the materials are output from the pickup port, while the support 103 continues to move along the spiral slide rail. Until it moves to the end of the drive shaft and disengages from the spiral slide rail, and then continues to move along the chute 321 of the chute sleeve 302 and enters the support storage bin 102. Figure 6 The schematic diagram of the pickup sequence of a double - helix dense storage and transfer device showing an embodiment of the present invention. For the convenience of display to avoid occlusion, taking the example of storing 6 materials in one circle, the number in actual use shall be subject to the application, such as Figure 6 As shown, when goods need to be picked up, first two materials 6n and 6n + 1 at the top are ejected in sequence, and then the drive shaft 104 drives the whole support 103 to rotate by 60°, so that the materials 6n + 2 and 6n + 3 move along the spiral line and align with the delivery port, waiting to be ejected. Repeat this process until all materials are ejected in sequence. During the ejection, the support 103 for fixing the materials will be unlocked from the lock with the material 001 when ejected. After disengaging from the fixation with the material 001, the support 103 will disengage from the spiral slide rail shaft 301 during the rotation process, and then be squeezed by the next support and continue to move along the chute 321 into the support storage bin 102.

[0043] The force on the chute sleeve 302 during driving can be simplified as a simply - supported beam. In order to avoid deformation of the chute sleeve 302 caused by excessive lateral pressure when the axial length of the storage bin is relatively long, the support 103 needs to bear lateral pressure during the movement along the spiral slide rail. As mentioned above, the pitch of the spiral guide rail of the spiral slide rail shaft 301 and the speed ratio between the chute sleeve 302 and the spiral slide rail shaft 301 can be flexibly set according to actual needs. For example, if the actual movement trajectory of the material is a double - helix line with a lead of 200 mm, the pitch of the spiral slide rail shaft can be designed to be 50 mm, and at the same time, the speed ratio between the chute sleeve 302 and the spiral slide rail shaft 301 is adjusted to 1:3, with opposite rotation directions.

[0044] In an embodiment of the present invention, the automatic unlocking module 502 is fixedly connected to the end of the support 103 by means of welding or bolt connection, etc. It can adopt, for example, a spring - triggered automatic lock or other common automatic unlocking devices. As mentioned above, according to the type of the automatic unlocking module, a corresponding automatic lock unlocking auxiliary mechanism needs to be set at the delivery port. For example, when a spring - type automatic lock is adopted, the automatic lock unlocking auxiliary mechanism can be an inclined plane, and the automatic lock is unlocked and the material is ejected when the support slides to the delivery port.

[0045] The double-helix dense storage transfer device can be applicable to the storage of materials for on-orbit construction and on-orbit maintenance. It should be understood that in practical applications, the double-helix dense storage transfer device should cooperate with spacecraft and space robots. The space robot is used to pick up the resources transferred to the shipping outlet. The spacecraft is used to provide the power required to drive the material flow. In one embodiment of the present invention, the spacecraft should also have the ability to communicate with the double-helix dense storage transfer device and request material supply. The present invention does not limit the type, specific power supply form, and mounting method of the spacecraft, nor does it limit the size of the spacecraft.

[0046] Although the embodiments of the present invention have been described above, it should be understood that they are presented only as examples and not as limitations. It will be apparent to those skilled in the relevant art that various combinations, variations, and changes can be made without departing from the spirit and scope of the present invention.
