Description

Technical Field

[0001] This invention belongs to the field of transportation technology for large spacecraft, and relates to a spacecraft transportation packaging box. Background Technology

[0002] Spacecraft transport packaging is an important piece of ground mechanical support equipment for spacecraft, used to provide suitable environmental conditions for outdoor relocation and transportation. Transport packaging has temperature, humidity, and pressure control functions, and reduces vibration and impact on the spacecraft inside the packaging during transportation.

[0003] With the development of aerospace technology, spacecraft are becoming increasingly larger, and the outer envelope of their packaging is also constantly increasing. Spacecraft transportation, considering factors such as launch site location and packaging envelope, employs road, rail, air, and sea transport. Generally, sea transport imposes the fewest restrictions on the packaging envelope. However, short-distance transport between the final assembly and testing facility and the seaport, and between the seaport and the launch site's final assembly and testing facility, still relies on road transport. Road transport envelopes are limited by factors such as overhead cables, traffic signs, and pedestrian overpasses, significantly restricting the height of the packaging.

[0004] Spacecraft are typically assembled, tested, experimented with, and docked with launch vehicles in a vertical configuration. The vertical configuration offers the best resistance to mechanical environments, but it often represents the maximum transport altitude envelope, making it difficult to meet the altitude constraints of road transport. Horizontal configurations offer a smaller transport altitude envelope, but the mechanical environment is more severe, especially the structural creep caused by prolonged horizontal storage, which can adversely affect the structural accuracy of the spacecraft.

[0005] Conventional shipping containers can only transport spacecraft in one orientation, either vertical or horizontal, and cannot be changed during transport. Summary of the Invention

[0006] The technical problem solved by this invention is to overcome the shortcomings of the prior art and propose a spacecraft transport packaging box that can realize rapid conversion between horizontal and vertical transport states, thereby adapting to different transport altitude envelope requirements.

[0007] The solution of the present invention is:

[0008] A spacecraft transport packaging box includes a box cover, a box bottom, and a vibration-damping base;

[0009] The box has an L-shaped frame structure at the bottom; a hollow cuboid structure for the cover; the cover is installed on the bottom to form the box body; a rubber sealing ring is installed at the joint between the cover and the bottom; the inner cavity of the box is a sealed space for storing external spacecraft; and a vibration damping base is installed horizontally at the bottom of the box.

[0010] In the aforementioned spacecraft transport packaging box, the bottom and cover are both welded from aluminum alloy components such as flanges, main beams, skins, and frames; polyurethane insulation material is filled between the inner and outer skins of the bottom and cover.

[0011] In one of the aforementioned spacecraft transport packaging boxes, two indoor air conditioning units, a pressure sensor, and a temperature sensor are installed on the inner wall of the box cover; two outdoor air conditioning units, a gas cylinder group, a gas distribution platform, and an electrical control box are installed on the outer wall of the box cover.

[0012] In the aforementioned spacecraft transport packaging box, the bottom of the box includes a frame structure, a spacecraft adapter, and a support device;

[0013] The frame structure is L-shaped; the spacecraft adapter is installed at the center of the upper surface of the horizontal wall of the frame structure; it is used to dock with the bottom of the hoisted external spacecraft; the support device is set at the center of the side wall of the vertical wall of the frame structure.

[0014] In the aforementioned spacecraft transport packaging box, when the frame structure is in a vertical state, the bottom of the external spacecraft is supported by a spacecraft adapter and fixed by bolts;

[0015] When the frame structure is in a horizontal position, it supports the side walls of the external spacecraft through a support device.

[0016] In the aforementioned spacecraft transport packaging box, six long lifting lugs for lifting and turning are symmetrically arranged on the side wall of the bottom of the box; three long lifting lugs are set on each side, located at the end of the horizontal wall, the end of the vertical wall, and the corner where the horizontal and vertical walls meet; the long lifting lugs enable the conversion between the horizontal and vertical states of the bottom of the box.

[0017] In the aforementioned spacecraft transport packaging box, the vibration damping base includes an upper base, a lower base, eight steel wire rope vibration isolators, and four lifting casters;

[0018] The upper and lower bases are both horizontally placed rectangular frame structures; the upper base is located above the lower base; eight wire rope vibration isolators are symmetrically arranged on the side walls of the mating surfaces of the upper and lower bases; and four lifting casters are respectively located at the four corners of the lower base.

[0019] In the aforementioned spacecraft transport packaging box, the lifting casters enable height adjustment; when the vibration-damping base is parked, the four lifting casters rise and the lower base touches the ground; when the vibration-damping base moves, the four lifting casters descend.

[0020] In the aforementioned spacecraft transport packaging box, when transported by sea, the box body is in a vertical position; when transported by road, the box body is first lifted from the vibration-damping base to the ground, the box body is converted to a horizontal position, and then the box body is hoisted onto the vibration-damping base for horizontal transport.

[0021] In the aforementioned spacecraft transport packaging box, eight vibration sensors are evenly arranged inside the bottom of the box to measure the rotation response during transport, and the vibration sensor signals are led to the electrical control box; two rollers are arranged on the outside of the bottom of the box to enable the bottom of the box to flip in horizontal and vertical states; four long lifting lugs are symmetrically arranged on the side wall of the lower base.

[0022] The advantages of this invention compared to the prior art are:

[0023] (1) The packaging box body and the vibration damping base of the present invention are designed independently, and different packaging box bodies can be designed according to different spacecraft. They can be used in conjunction with the same vibration damping base to realize modular replacement of the box body, which is economical.

[0024] (2) The present invention uses a detachable mechanical interface between the box body and the vibration damping base. The box body has two mutually perpendicular mounting surfaces, which can realize the rapid conversion between the horizontal and vertical transportation states of the aircraft when outdoors. Thus, the long-term sea transport adopts the vertical state with a good mechanical environment, and the short-term road transport adopts the horizontal state with a small height envelope.

[0025] (3) The packaging box of the present invention can keep the spacecraft in a horizontal state during short-distance road transportation and in a vertical state during long-distance transportation, thus solving the problem that the mechanical environment of horizontal transportation of spacecraft is harsh and the height envelope of vertical transportation breaks through the limitations of road transportation.

[0038] When the frame structure 201 is turned to a horizontal state, the support device 203 provides support for the side wall of the external spacecraft.

[0039] In addition, six long lifting lugs 204 for lifting and turning are symmetrically arranged on the side wall of the bottom of the container 2; three long lifting lugs 204 are set on each side, located at the end of the horizontal wall, the end of the vertical wall, and the corner where the horizontal wall and the vertical wall meet; the long lifting lugs 204 are used to realize the conversion between the horizontal and vertical states of the bottom of the container 2.

[0041] The height is adjusted by lifting casters 304; when the vibration damping base 3 is parked, the four lifting casters 304 are raised and the lower base 302 touches the ground; when the vibration damping base 3 moves, the four lifting casters 304 are lowered.

[0042] like Figure 5 As shown, when transported by sea, the box is in a vertical position; when transported by road, the box is first lifted from the vibration damping base 3 to the ground, the box is then converted to a horizontal position, and then the box is hoisted onto the vibration damping base 3 for horizontal transport.

[0043] Eight vibration sensors are evenly arranged inside the bottom of the box 2 to measure the rotation response during transportation. The vibration sensor signals are led to the electrical control box 104.

Four long lifting lugs are symmetrically arranged on the side wall of the lower base 302.

[0044] Example

[0045] An embodiment of the present invention provides a spacecraft transport packaging box, which is divided into three parts: box bottom 1, box cover 2, and vibration damping base 3.

[0046] like Figure 1 As shown, the box bottom 1 and box cover 2 form the box body. The box bottom 1 and box cover 2 are connected by a detachable buckle, and a rubber sealing ring is installed between the connecting surfaces. The inside of the box body is a sealed space for storing spacecraft. The main structure of the box bottom 1 and box cover 2 is welded from aluminum alloy components such as flanges, main beams, skins, and frames. Polyurethane insulation material is filled between the inner and outer skins.

[0047] like Figure 2 As shown, two indoor air conditioning units, pressure and temperature sensors are installed inside the enclosure, while outdoor air conditioning unit 101, gas cylinder group 102, gas distribution platform 103, electrical control box 104 and other equipment are installed on the outside.

[0048] like Figure 3 As shown, the bottom of the container consists of a bottom structure 201, a spacecraft adapter 202, and a support device 203. The bottom structure 201 has an L-shaped cross-section. The spacecraft adapter 202 is installed on one side of the bottom structure 201, and the spacecraft is vertically suspended onto the spacecraft adapter 202 and fixed with bolts. The support device 203 is located on the other side of the bottom to support the spacecraft when it is turned to a horizontal position. Six long lifting lugs 204 for lifting and turning are symmetrically arranged on the outer side of the bottom. Two of the long lifting lugs 203 can be replaced with rollers for turning the container horizontally and vertically.

[0049] like Figure 4 As shown, the vibration damping base 3 consists of an upper base 301 and a lower base 302, which are connected by eight sets of steel wire rope vibration isolators 303.

[0050] like Figure 5 As shown, during long-distance sea transport, the container is installed vertically on the vibration damping base 3, which is fixed to the transport ship. During short-distance road transport, the container is first lifted from the vibration damping base 3 to the ground, and then the container is converted to a horizontal state by using rollers and a crane. Finally, the container is lifted back onto the vibration damping base 3 and transported horizontally through the road transport section.

[0051] In this invention, the packaging box body and the vibration damping base are designed independently, allowing for different packaging box bodies to be designed according to different spacecraft. They can be used in conjunction with the same vibration damping base to achieve modular replacement of the box body, resulting in good economic efficiency.

[0052] The present invention employs a detachable mechanical interface between the box body and the vibration-damping base. The box body has two mutually perpendicular mounting surfaces, enabling rapid switching between horizontal and vertical transport states for the spacecraft outdoors. This allows for a vertical state with favorable mechanical environment during long-distance sea transport and a horizontal state with a small height envelope during short-distance road transport. The box can keep the spacecraft horizontal during short-distance road transport and vertical during long-distance transport, solving the problems of harsh mechanical environment during horizontal transport and the height envelope exceeding the limitations of road transport during vertical transport.
