Description

Technical Field

[0001] This invention relates to the technical field of rocket body assembly, and more particularly to a vertical test platform for rockets and its usage method. Background Technology

[0002] Currently, during the rocket assembly process, the rocket body needs to be quickly assembled, stored, and tested in the rocket factory, while the assembly, storage, and testing of the rocket core stage, boosters, etc., all require the use of a test platform.

[0003] Regarding the aforementioned technologies, the applicant has found that since rockets are generally quite tall now, and traditional vertical test platforms are fixed and have a limited range of applicable heights, they are no longer suitable for assembling, parking, and testing rockets at higher altitudes. Therefore, there is an urgent need for one or more operational test platforms that can move up and down and can be safely evacuated for the assembly, parking, and testing of rockets at current heights. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a vertical testing platform for rockets and its usage method. It has the effect of adjusting the height, and the height adjustment is not affected even when workers are working on the platform. This expands the applicability of the platform to the assembly, parking, and testing of rockets at higher altitudes, while also improving the work efficiency of workers.

[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows:

[0006] A vertical test platform for rockets includes support columns, multiple support columns vertically positioned at the perimeter, horizontal platform modules between the support columns, and several platform modules arranged vertically. The platform modules slide up and down on the support columns along the vertical direction of the support columns. The platform modules have working through holes adapted to the rocket body, located in the middle of the platform modules. The platform modules are arranged in a centrally symmetrical manner. Each platform module includes a sliding base plate and a sliding plate. The sliding base plate is slidably connected to the support columns, and the sliding plate slides on the sliding base plate along the horizontal direction of the sliding base plate, moving closer to or away from the support columns.

[0007] Furthermore, the platform module includes an edge flip plate, which is hinged to a sliding plate. The edge flip plate is located at the edge of the sliding plate away from the sliding base plate, and several edge flip plates are provided.

[0008] Furthermore, the platform module includes a central flip plate, which is hinged to an edge flip plate, with the central flip plate positioned on the side of the edge flip plate near the working through hole.

[0009] Furthermore, the support column is provided with an up-and-down sliding assembly, which connects the support column and the sliding base plate. The up-and-down sliding assembly drives the sliding base plate to slide up and down along the vertical direction of the support column.

[0010] Furthermore, the sliding base plate is provided with a front and rear sliding assembly, which connects the sliding base plate and the sliding plate. The front and rear sliding assembly drives the sliding plate to slide back and forth along the horizontal direction of the sliding base plate.

[0011] Furthermore, an edge flipping assembly is hinged to the sliding plate, the edge flipping assembly connects the sliding plate and the edge flipping plate, and the edge flipping assembly drives the edge flipping plate to flip on the sliding plate.

[0012] Furthermore, a central flipping assembly is hinged to the edge flipping plate, the central flipping assembly connects the edge flipping plate and the central flipping plate, and the central flipping assembly drives the central flipping plate to perform a flipping motion on the edge flipping plate.

[0013] Furthermore, a rotating support beam assembly is rotatably connected to the lower side of the sliding base plate near the sliding plate. The rotating support beam assembly rotates in the horizontal direction and is positioned below the sliding plate and in contact with the sliding plate.

[0014] A method for using a vertical test platform for rockets includes the following steps:

[0015] Step 1: The up-and-down sliding assembly is activated, which drives the sliding base plate to move up and down along the direction of the support column. When the sliding base plate reaches the working position, the up-and-down sliding assembly locks itself, so that the sliding base plate enters the working state.

[0016] Step 2: The front and rear sliding components are activated, driving the sliding plate to move back and forth along the horizontal direction of the sliding base plate. When the sliding plate reaches the working position, the front and rear sliding components self-lock, so that the sliding plate enters the working state.

[0017] Step 3: With both the edge flip plate and the center flip plate in a horizontal position, the rocket body is confined within the working through hole, and the rocket body working operation is carried out.

[0018] Step 4: After the rocket body operation is completed, the central flip plate is driven to flip by the central flip assembly, and then the edge flip plate is driven to flip by the edge flip assembly, and so on, to achieve the flipping and removal state.

[0019] Step 5: The sliding plate is driven by the front and rear sliding components to slide away from the rocket body and withdraw, while the rotating support beam assembly rotates away from the rocket body, finally achieving the withdrawal state.

[0020] Furthermore, after the rocket body is removed, the upper and lower positions of the sliding base plate are adjusted by sliding the upper and lower sliding components to adapt to the next operation of the rocket body at different heights. Steps one to five are repeated to perform operations in working and removal states, so as to realize the assembly, parking and testing of rocket bodies at different heights.

[0021] In summary, compared with the prior art, the beneficial effects of the above technical solution are:

[0022] (1) It has the effect of adjusting the height. Even if there are workers working on the platform, it will not affect the height adjustment. This expands the scope of application for the assembly, parking and testing of rockets with higher heights, and also improves the work efficiency of workers.

[0023] (2) Each platform module is configured with a separate drive component, and each platform module can adjust its height independently;

[0024] (3) The platform modules have low maintenance costs. They are all steel structures. There are no hidden or complicated installations between the various platform modules, which greatly facilitates the later maintenance. The drive components are also common drive methods. Combined with mature maintenance and repair methods, the later maintenance costs are greatly reduced.

[0025] (4) The platform has a good operating space. The operating space at the top of the platform is almost 100% utilized, and most of its drive components are located at the bottom of the platform, which greatly improves the working area. Attached Figure Description

[0039] The principles and features of the present invention are described below with reference to all the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0040] This invention discloses a vertical test platform for rockets and its usage method.

[0041] Reference Figure 1 A vertical test platform for rockets includes support columns 1, with multiple support columns 1 vertically positioned at the perimeter. In this embodiment, six support columns 1 are provided, three on each side. Horizontal platform modules 2 are provided between the six support columns 1, and several platform modules 2 are arranged vertically. In this embodiment, three platform modules 2 are provided for reference. The platform modules 2 slide up and down along the vertical direction of the support columns 1.

[0042] Reference Figure 1 and Figure 2The platform module 2 is provided with a working through hole 21 adapted to the rocket body 3. Different shapes and sizes of working through holes 21 are pre-made according to the different shapes of the rocket body 3. The working through hole 21 is located in the middle of the platform module 2. When the rocket body 3 is assembled, parked and tested, the rocket body 3 is placed in the working through hole 21.

[0043] Reference Figure 1 and Figure 2 Platform module 2 is centrally symmetrically arranged and includes a sliding base plate 22 and a sliding plate 23. The two sliding base plates 22 are respectively positioned on both sides and slidably connected to the corresponding support column 1. The sliding plate 23 slides along the horizontal direction of the sliding base plate 22, moving closer to or away from the support column 1. This invention has the effect of adjusting the height, and the height adjustment is not affected even when workers are working on the platform, expanding the applicability of assembly, parking, and testing of rockets at higher altitudes, while also improving the work efficiency of workers.

[0044] Reference Figure 3 and Figure 4 The platform module 2 also includes an edge flip plate 24, which is hinged to the sliding plate 23. The edge flip plate 24 is located at the edge of the sliding plate 23 away from the sliding base plate 22. Several edge flip plates 24 can be provided. In this embodiment, two edge flip plates 24 are provided on one sliding plate 23.

[0045] Reference Figure 5 and Figure 6 The platform module 2 also includes a central flip plate 25, which is hinged to the edge flip plate 24. The central flip plate 25 is located on the side of the edge flip plate 24 near the working through hole 21. One central flip plate 25 is set on one edge flip plate 24, and the two central flip plates 25 located on the same side of the sliding plate 23 are symmetrically distributed.

[0046] Reference Figure 5 and Figure 6 Each platform module 2 is equipped with a separate drive component, and each platform module 2 can adjust its height independently. The support column 1 is equipped with a vertical sliding component 11, which connects the support column 1 and the sliding base plate 22. The vertical sliding component 11 drives the sliding base plate 22 to slide up and down along the vertical direction of the support column 1.

[0047] Reference Figure 7 and Figure 8 The sliding base plate 22 is provided with a front and rear sliding assembly 231. The front and rear sliding assembly 231 connects the sliding base plate 22 and the sliding plate 23. The front and rear sliding assembly 231 drives the sliding plate 23 to slide back and forth along the horizontal direction of the sliding base plate 22.

[0048] Reference Figure 7 An edge flipping assembly 241 is hinged to the sliding plate 23. The edge flipping assembly 241 connects the sliding plate 23 and the edge flipping plate 24. The edge flipping assembly 241 drives the edge flipping plate 24 to flip on the sliding plate 23.

[0049] Reference Figure 7 A center flipping assembly 251 is hinged to the edge flipping plate 24. The center flipping assembly 251 connects the edge flipping plate 24 and the center flipping plate 25. The center flipping assembly 251 drives the center flipping plate 25 to flip on the edge flipping plate 24.

[0050] Reference Figure 1 , Figure 9 and Figure 10 A rotating support beam assembly 4 is rotatably connected to the lower side of the sliding base plate 22 near the sliding plate 23. The rotating support beam assembly 4 rotates in the horizontal direction and is positioned below the sliding plate 23, abutting against it. Based on the dynamic load requirements of the rocket body 3 during operation, the position of the rotating support beam assembly 4 is adjusted in real time to dynamically select load support for the sliding plate 23, the edge flipping plate 24, and the center flipping plate 25, thereby improving the overall load stability of the operating platform.

[0051] Reference Figure 10 Platform module 2 has low maintenance costs. All modules are made of steel and there are no hidden or complicated installations between them, which greatly facilitates later maintenance. The drive components are also common drive methods. Combined with mature maintenance and repair methods, the maintenance costs are greatly reduced.

[0052] Reference Figure 7 , Figure 8 and Figure 9 In this embodiment, the platform module 2 mainly includes a sliding base plate 22, a sliding plate 23, an edge flipping plate 24, a center flipping plate 25, and a rotating support beam assembly 4. The above structure is the basic component structure of the platform module 2. At the same time, a hydraulic cylinder for flipping is also installed on it to realize the flipping movement of the center flipping assembly 251 and the edge flipping assembly 241, as well as the front and back sliding assembly 231 for front and back sliding movement.

[0053] Reference Figure 5 and 6 In this embodiment, the support column 1 consists of three columns on one side, forming two sides in total. The vertical sliding component 11 consists of four columns at the four corners, on which sliding guide rails and racks for vertical sliding motion are installed. Its function is to support the vertical test platform and enable the vertical test platform to slide vertically.

[0054] Reference Figure 5 and 6In this embodiment, the structure of the vertical sliding component 11 includes upper and lower guide rail racks 111, upper and lower motors 112, upper and lower pulleys 113, upper and lower gears 114, and protective support shells 115. There is a set of this structure on the upper and lower sides of a single protective support shell 115, so as to realize the vertical sliding movement of a single-layer vertical test platform.

[0055] Reference Figure 7 and 8 In this embodiment, the structure of the front and rear sliding assembly 231 includes front and rear motors 2311, front and rear gears 2312 and front and rear guide racks 2313. The front and rear guide racks 2313 are mounted on the sliding base plate 22, and the front and rear motors 2311 are mounted on the side of the sliding plate 23. Their function is to drive the sliding plate 23, the edge flip plate 24 and the center flip plate 25 to move out of the working area of ​​the rocket together.

[0056] Reference Figure 7 In this embodiment, the edge flipping assembly 241 and the center flipping assembly 251 mainly realize the vertical flipping of the edge flipping plate 24 and the horizontal flipping of the center flipping plate 25. The boosters are set on both sides of the rocket body 3, which will interfere when the edge flipping plate 24 flips and is withdrawn. Therefore, the center flipping plate 25 is set to flip horizontally. The edge flipping plate 24 will drive the center flipping plate 25 to flip vertically together. The driving structure of the edge flipping assembly 241 and the center flipping assembly 251 is usually a telescopic component structure such as the edge flipping hydraulic cylinder 2411 and the center flipping hydraulic cylinder 2511.

[0057] Reference Figure 9 and Figure 10 In this embodiment, the rotating support beam assembly 4 includes a rotating shaft 41, a support beam frame 42, and a rotating motor 43. Its main function is to support the sliding plate 23, the edge flipping plate 24, and the center flipping plate 25 when the vertical working platform is in operation.

[0058] Reference Figure 11 and Figure 12 Platform module 2 has a good operating space, with the upper part of the platform having almost 100% utilization of the operating space. Its drive components are mostly located at the bottom of the platform, which greatly improves the working area.

[0059] Reference Figures 1 to 12 A method for using a vertical test platform for rockets includes the following steps:

[0060] Step 1: The up-and-down sliding assembly 11 is activated, which drives the sliding base plate 22 to move up and down along the direction of the support column 1. When the sliding base plate 22 reaches the working position, the up-and-down sliding assembly 11 locks itself, so that the sliding base plate 22 enters the working state.

[0061] Step 2: The front and rear sliding assembly 231 is activated, which drives the sliding plate 23 to move back and forth along the horizontal direction of the sliding base plate 22. When the sliding plate 23 reaches the working position, the front and rear sliding assembly 231 self-locks, so that the sliding plate 23 enters the working state.

[0062] Step 3: Both the edge flip plate 24 and the center flip plate 25 are in a horizontal state, which restricts the rocket body 3 within the working through hole 21, and the working operation of the rocket body 3 is carried out.

[0063] Step 4: After the rocket body 3 finishes its work, the central flip plate 25 is driven to flip by the central flip assembly 251, and then the edge flip plate 24 is driven to flip by the edge flip assembly 241, and so on, to achieve the flipping and evacuation state.

[0064] Step 5: The sliding plate 23 is driven by the front and rear sliding components 231 to slide away from the rocket body 3, and the rotating support beam assembly 4 rotates away from the rocket body 3, finally achieving the withdrawal state.

[0065] In addition, after the rocket body 3 is removed, the upper and lower positions of the sliding base plate 22 are adjusted by sliding the upper and lower sliding assembly 11 to adapt to the next operation of the rocket body 3 at different heights. Steps one to five are repeated to perform operations in working state and removal state, so as to realize the assembly, parking and testing of the rocket body 3 at different heights.

[0066] The implementation principle of a vertical test platform for rockets and its usage method according to an embodiment of the present invention is as follows:

[0067] When the vertical test platform is in operation, the vertical sliding component 11 will be in a self-locking or moving state, and the platform module 2 will be in a balanced state. Maintaining this state requires the front and back sliding component 231 to be self-locking, and the bottom rotating support beam component 4 will also be in operation.

[0068] When in operation, if the platform module 2 needs to change its working position, the up and down motor 112 in the up and down sliding component 11 will work, and the up and down guide rack 111, up and down gear 114 and up and down pulley 113 will move. At the same time, through the meshing of the gear rack, the up and down pulley 113 will move up and down on the up and down guide grooves, and the platform module 2 will move up and down. When the platform module 2 reaches the working position, the up and down motor 112 will self-lock, and the platform module 2 will maintain a certain posture for operation.

[0069] After the work is completed, the vertical testing platform will be evacuated. During the evacuation process, the central flip plate 25 is first flipped upwards by the central flip hydraulic cylinder 2511 in the central flip assembly 251. Then, driven by the edge flip hydraulic cylinder 2411 of the edge flip assembly 241, the edge flip plate 24 flips upwards, simultaneously causing the central flip plate 25 to flip backwards. Then, the front and rear sliding assembly 231, with front and rear motors 2311 installed on one side of the sliding plate 23 (one at the front and one at the back), drives the front and rear gears. When wheel 2312 rotates, front and rear gears 2312 mesh with front and rear guide racks 2313, causing sliding plate 23 to move back and forth. At the same time, edge flipping plate 24 is connected to sliding plate 23, which will drive edge flipping plate 24 and center flipping plate 25 to move back and forth. Finally, the rotary motor 43 in the rotary support beam assembly 4 drives the rotary shaft 41 to rotate the support beam frame 42 inward, thus realizing the removal of the vertical test platform. If the overall position of the vertical test platform is not ideal, the vertical position of platform module 2 can be adjusted by sliding component 11.

[0070] In the next operation, simply reverse the evacuation state and combine it with the operation in the working state.

[0071] In addition, by repeatedly cycling through the above working and evacuation operations, the assembly, parking, and testing of multiple rocket bodies 3 can be achieved.

[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
