Description

Technical Field

[0001] This invention belongs to the field of spacecraft transportation support, specifically, it relates to an adjustable support device suitable for the transportation of whole satellites. Background Technology

[0002] Currently, satellites are typically transported to launch sites by securing them in L-shaped transport fixtures and then packing them into boxes. For large, stepped satellites, due to the heavy payload and complex transport mechanics, the usual method is to remove the top payload and transport them separately. With increasingly stringent requirements for satellite launch site development efficiency, minimizing the disassembly and reassembly of the payload before and after transport, and providing a reliable environment for the entire satellite's transport, have become crucial.

Summary of the Invention

[0009] In view of the deficiencies in the prior art, the purpose of this invention is to provide an adjustable support device suitable for the transportation of whole satellites.

[0010] An adjustable support device for whole satellite transportation according to the present invention includes: an adjustable support rod 1, a process support plate 2, a top adapter plate 3, a shock-absorbing pad 4, and a precision measuring prism 5; the process support plate 2 is lower than the top adapter plate 3, and the lower honeycomb panel of the satellite is connected to the base plate of the L-shaped transportation fixture through the process support plate 2; the bottom of the adjustable support rod 1 is connected to the base plate of the L-shaped transportation fixture, and the top of the adjustable support rod 1 provides support for the upper honeycomb panel 6 and the load of the satellite through the top adapter plate 3 and the shock-absorbing pad 4; the flatness of the upper honeycomb panel 6 is obtained according to the precision measuring prism 5 installed on the surface of the upper honeycomb panel 6, thereby determining the support height of the adjustable screw 1 and reducing the stress level of the upper honeycomb panel 6 during transportation; the lower honeycomb panel and the upper honeycomb panel 6 of the satellite form a stepped shape of the satellite head.

[0011] Preferably, the adjustable support rod 1 includes a lower support assembly 11 and an upper adjustable screw 12. The lower support assembly 11 is connected to the L-shaped transport fixture by screws. The lower support assembly 11 and the upper adjustable screw 12 are connected by screws. The upper adjustable screw 12 provides support for the upper honeycomb panel 6 and adjusts the support height according to the measured flatness data.

[0012] Preferably, after the upper adjustable screw 12 is adjusted to the corresponding height, it is locked by the nut on the adjustable support rod 1.

[0013] Preferably, the top adapter plate 3 is made of aluminum alloy and is fixedly connected to the upper honeycomb plate 6 by screws.

[0014] Preferably, the top adapter plate 3 transmits the supporting force of the adjustable support rod 1 to the upper honeycomb plate 6, while also bearing the impact stress of the adjustable support rod 1 during transportation.

[0015] Preferably, the size of the top adapter plate 3 is larger than the upper surface of the adjustable support rod 1, thereby increasing the stress-bearing area of ​​the upper honeycomb plate 6 and reducing stress.

[0016] Preferably, the shock-absorbing pad 4 is made of rubber and is connected to the upper honeycomb plate 6 by screws. The shock-absorbing pad 4 is located between the upper honeycomb plate 6 and the top adapter plate 3.

[0017] Preferably, the shock-absorbing pad 4 reduces the transmission of vibration and impact from the bottom L-shaped transport fixture to the upper honeycomb panel 6 during transportation.

[0018] Preferably, the precision measuring prism 2 is made of glass and is attached to the surface of the upper honeycomb panel 6. The flatness of the upper honeycomb panel 6 is obtained through ground precision measuring equipment. The obtained flatness data provides a basis for adjusting the support height, ultimately ensuring that the upper honeycomb panel 6 and the load gravity counteract the support force, so that the honeycomb panel can be transported horizontally.

[0019] Preferably, the process support plate 2 is an aluminum alloy plate with relief holes. The process support plate 2 provides an interface with the satellite and the L-shaped transport fixture, and the three are connected into a whole by screws. The process support plate 2 adopts the same interface as the lower honeycomb panel of the satellite, is installed on the satellite, and is connected to the L-shaped transport fixture by screws, replacing the lower honeycomb panel of the satellite to bear the mechanical environment during transportation.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. Under the premise of meeting the requirements for satellite transportation support, the present invention uses a process support plate to replace the formal honeycomb plate, which has the advantages of low risk and high reliability.

[0022] 2. The present invention uses an adjustable support rod in conjunction with a precision measuring prism to achieve completely horizontal transportation of the upper honeycomb panel, thereby achieving low stress during honeycomb panel transportation and improving the reliability of the entire transportation process.

[0023] 3. This invention provides a height adjustment basis based on the precision measurement prism pasted on the top, solving the problem that the payload of the stepped satellite head cannot be transported with the whole satellite, thus improving the efficiency of satellite development.

[0031] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the scope of protection of the present invention.

[0032] like Figures 1 to 4 As shown, an adjustable support device for satellite transportation according to the present invention mainly consists of two separate left and right parts, including: an adjustable support rod 1, a process support plate 2, a top adapter plate 3, a shock-absorbing pad 4, and a precision measuring prism 5. The present invention provides two parts: a fixed support and an adjustable support. The left process support plate 2 uses the same interface as the original satellite honeycomb panel and is installed on the satellite, while also being connected to an L-shaped transportation fixture by screws, serving as a substitute for the original satellite honeycomb panel to withstand the mechanical environment during transportation. The right side uses the adjustable support rod 1, which provides support for the upper honeycomb panel 6 and the load through the top adapter plate 3 and the shock-absorbing pad 4. The flatness of the honeycomb panel is obtained by the precision measuring prism 5 installed on the surface of the upper honeycomb panel 6, thereby determining the support height of the adjustable screw 1, achieving low-stress horizontal transportation of the honeycomb panel.

[0033] The adjustable support rod 1 of the present invention includes a lower support assembly 11 and an upper adjustable screw 12. The lower support assembly 11 is connected to the L-shaped transport fixture by screws. The upper and lower parts are connected by screws. The upper adjustable screw 12 provides support for the upper honeycomb panel 6. At the same time, the support height can be adjusted according to the measured flatness data. After the height adjustment rod is adjusted to a suitable height, it is locked by the nut on the adjustment rod.

[0034] The process support plate 2 is an aluminum alloy plate with weight-reducing holes. The support plate provides an interface with the satellite and the L-shaped transport fixture. The three are connected into a whole by screws. The process support plate 2 replaces the formal satellite cellular panel to bear the mechanical load during transportation. Rectangular holes are opened on the surface of the process support plate 2 for weight reduction.

[0035] The top adapter plate 3 is made of aluminum alloy and is fixedly connected to the upper honeycomb plate 6 by screws. Its area and thickness can be adjusted according to actual conditions. The top adapter plate can transfer the supporting force of the adjustable support rod 1 to the honeycomb plate, and at the same time bear the impact stress of the support rod during transportation. Its size is generally larger than the upper surface of the support rod to increase the stress-bearing area of ​​the upper honeycomb plate and reduce stress.

[0036] The shock-absorbing pad 4 is made of rubber and is connected to the upper honeycomb plate 6 by screws. The shock-absorbing pad 4 is located between the upper honeycomb plate 6 and the top adapter plate 3 and plays a shock-absorbing role. It is mainly used to reduce the vibration and impact transmitted from the bottom L-shaped transport fixture to the upper honeycomb plate during transportation.

[0037] The precision measuring prism 2 is made of glass and is adhered to the surface of the upper honeycomb panel 6. The flatness of the upper honeycomb panel 6 can be obtained through ground-based precision measuring equipment. Furthermore, the obtained flatness data provides a basis for adjusting the support height, ultimately ensuring that the upper honeycomb panel 6 and the load gravity counteract the support force, enabling the honeycomb panel to be transported horizontally and achieving active height adjustment of the support screw.

[0038] The specific implementation of the present invention has been described above. The application of the present invention has significant benefits in terms of improving the transportation of the entire satellite, reducing the disassembly and assembly of the payload, and facilitating process operations.
