Description

Technical Field

[0001] This utility model relates to the field of launch vehicle technology, and in particular to a service platform for rocket wall operation. Background Technology

[0002] The rocket fuselage is a major component of the rocket's outer shell, forming the rocket's structural shell together with stringers, frame rings, and other elements. The assembly process involves both upright and horizontal states. The horizontal state facilitates production and transportation, while the upright state is suitable for launch and fueling. Currently, the rocket fuselage requires different service platforms for the upright and horizontal states, necessitating the manufacture and deployment of two independent service platforms. These platforms have high maintenance and material costs, occupy significant space, and require multiple adjustments and repositionings to facilitate the transition from horizontal to upright positions. Furthermore, the rocket fuselage must first be detached from the horizontal service platform's fixing devices before being transferred to the upright service platform using erection equipment. This process is time-consuming and involves multiple adjustments. During these two platform transfers, the rocket fuselage undergoes a process of untying, moving, and re-fixing, which can lead to attitude deviations due to inconsistencies in the two fixing benchmarks, and may even cause structural damage due to vibrations or collisions during the transfer process. Utility Model Content

[0003] The technical problem to be solved by this utility model embodiment is to provide a service platform for rocket wall operation, which can adapt to the horizontal and vertical states of the rocket wall through integrated design, directly reducing equipment manufacturing and maintenance costs.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model embodiment is as follows: A service platform for rocket wall operation includes: The first side frame is set vertically; A second side frame arranged parallel to the first side frame; A first horizontal frame horizontally mounted on the first side frame; A second horizontal frame is provided on the second side frame and is arranged parallel to the first horizontal frame. A planar frame disposed on the first side frame and the second side frame, and perpendicularly fixedly connected to the first side frame and the second side frame; A first fixing plate vertically mounted on the first side frame; A second fixing plate is disposed parallel to the first fixing plate and on the second side frame; The first fixing plate and the second fixing plate are fixedly connected to the erecting frame of the rocket wall. When the erecting frame erects or flattens the rocket wall, it simultaneously drives the service platform to change from a horizontal state to an erected state or from an erected state to a horizontal state.

[0005] Optionally, the aforementioned service platform may also include: A first guardrail is installed on the first side frame and the second side frame; A second guardrail is installed on the first horizontal frame and the second horizontal frame.

[0006] Optionally, a first passageway door is provided on the first horizontal frame and the second horizontal frame.

[0007] Optionally, the first horizontal frame and the second horizontal frame are provided with a first support plate, except at the first passage door.

[0008] Optionally, the planar frame is provided with a second passage door at a location corresponding to the first horizontal frame and the second horizontal frame.

[0009] Optionally, the planar frame is provided with a second support plate, except at the second passage door.

[0010] Optionally, the aforementioned service platform may also include: A first connecting frame is horizontally disposed on the first side frame, opposite to the first horizontal frame. A first storage escalator rotatably connected to the first connecting frame; A second connecting frame is arranged parallel to the first connecting frame and opposite to the second horizontal frame, and is horizontally arranged on the second side frame; A second storage escalator that is rotatably connected to the second connecting frame.

[0011] Optionally, the aforementioned service platform may also include: A third guardrail is installed on the first connecting frame and the second connecting frame.

[0012] Optionally, the first side frame and the second side frame are rectangular support frames.

[0013] Optionally, the first horizontal frame and the second horizontal frame are triangular support frames.

[0014] The above-described solution of this utility model embodiment has at least the following beneficial effects: The above-described solution of this utility model embodiment, through integrated design, requires only one service platform to adapt to the horizontal and vertical states of the rocket wall, directly reducing equipment manufacturing and maintenance costs, while saving the material consumption required for two platforms, meeting the engineering design requirements of lightweight and low cost.

[0015] A single platform can switch states synchronously with the arrow wall's posture (horizontal-vertical or vice versa), eliminating the need to reserve additional storage or operating space for a second platform, significantly improving site utilization and simplifying spatial planning of the work area.

[0016] By rigidly linking with the erecting frame, the service platform moves synchronously during the erection / leveling of the arrow wall, eliminating the need for manual disassembly, transfer, or re-fixing of the platform. This removes the intermediate steps of switching platforms twice, significantly shortening the total time for arrow wall attitude conversion and improving overall service operation efficiency.

[0017] The service platform is rigidly connected to the erecting frame via a fixed plate, and the arrow wall and the platform remain relatively fixed at all times. There is no separation or transfer operation during attitude conversion, which avoids attitude errors caused by multiple fixed reference deviations. At the same time, it eliminates the risk of structural damage caused by vibration and collision during transfer, ensuring the assembly accuracy and structural integrity of the arrow wall.

[0018] The first and second guardrails can form a continuous and enclosed protective space in both horizontal and vertical platform states. The protective range is adjusted synchronously with the platform's posture to ensure that operators can obtain reliable safety protection in both states, avoid the risk of falling, and further improve operational safety.

Detailed Implementation

[0022] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0023] like Figure 1 , 2 As shown, an embodiment of this utility model provides a service platform for rocket wall operation, comprising: The first side frame 11 is set vertically; A second side frame 12 is arranged parallel to the first side frame 11; A first horizontal frame 21 is horizontally mounted on the first side frame 11; A second horizontal frame 22 is disposed parallel to the first horizontal frame 21 and on the second side frame 12; A planar frame 3 is disposed on the first side frame 11 and the second side frame 12 and is perpendicularly and fixedly connected to the first side frame 11 and the second side frame 12; A first fixing plate 41 is vertically mounted on the first side frame 11; A second fixing plate 42 is disposed on the second side frame 12, parallel to the first fixing plate 41. The first fixing plate 41 and the second fixing plate 42 are fixedly connected to the erecting frame of the rocket wall. When the erecting frame erects or flattens the rocket wall, it simultaneously drives the service platform to change from a horizontal state to an erected state or from an erected state to a horizontal state.

[0024] Specifically, the aforementioned service platform also includes: A first guardrail 51 is provided on the first side frame 11 and the second side frame 12; A second guardrail 52 is provided on the first horizontal frame 21 and the second horizontal frame 22.

[0025] In practical operation, the service platform is fixedly connected to the erecting frame of the rocket wall through the first fixing plate 41 and the second fixing plate 42, realizing the rigid linkage between the service platform and the erecting frame; after assembly, the first side frame 11 and the second side frame 12 are arranged vertically opposite each other, the first horizontal frame 21 and the second horizontal frame 22 are arranged horizontally opposite each other, the planar frame 3 is vertically connected to the two side frames, and the first guardrail 51 and the second guardrail 52 respectively enclose the two side frames and the horizontal frame, forming a safe operating space.

[0026] Initial state of rocket wall erection: The rocket wall is in a flat position, and the service platform fixed to it is kept in a horizontal position. At this time, the operator can perform service operations such as pipeline connection and equipment inspection on the flat rocket wall through the first horizontal frame 21 and the second horizontal frame 22. Erection action: The erection frame is activated, which drives the rocket wall to rotate upward to carry out the erection operation; since the service platform is fixed to the erection frame through the fixing plate, the erection frame will drive the entire service platform to rotate simultaneously while driving the rocket wall to be erected. Final state: When the rocket wall is erected and reaches the preset vertical attitude, the service platform also rotates from the horizontal state to the erected state, fitting against the side of the vertical rocket wall. The operator can continue to carry out subsequent service operations on the first side frame 11, the second side frame 12 and the plane frame 3 after the rocket is erected. The first guardrail 51 and the second guardrail 52 can provide safety protection for operators in both the horizontal and vertical states of the service platform, preventing personnel from falling from the edge of the service platform and ensuring personal safety during service operations.

[0027] In this example, through integrated design, only one service platform is needed to adapt to the horizontal and vertical states of the rocket wall, directly reducing equipment manufacturing and maintenance costs, while saving the material consumption required for two platforms, which meets the engineering design requirements of lightweight and low cost.

[0028] A single platform can switch states synchronously with the arrow wall's posture (horizontal-vertical or vice versa), eliminating the need to reserve additional storage or operating space for a second platform, significantly improving site utilization and simplifying spatial planning of the work area.

[0029] By rigidly linking with the erecting frame, the service platform moves synchronously during the erection / leveling of the arrow wall, eliminating the need for manual disassembly, transfer, or re-fixing of the platform. This removes the intermediate steps of switching platforms twice, significantly shortening the total time for arrow wall attitude conversion and improving overall service operation efficiency.

[0030] The service platform is rigidly connected to the erecting frame via a fixed plate, and the arrow wall and the platform remain relatively fixed at all times. There is no separation or transfer operation during attitude conversion, which avoids attitude errors caused by multiple fixed reference deviations. At the same time, it eliminates the risk of structural damage caused by vibration and collision during transfer, ensuring the assembly accuracy and structural integrity of the arrow wall.

[0031] The first guardrail 51 and the second guardrail 52 can form a continuous and closed protective space in both the horizontal and vertical states of the platform. The protective range is adjusted synchronously with the posture of the platform to ensure that the operator can obtain reliable safety protection in both states, avoid the risk of falling, and further improve the safety of operation.

[0032] In an optional embodiment of the present invention, a first passage door 61 is provided on the first horizontal frame 21 and the second horizontal frame 22.

[0033] Except for the first passage door 61, the first horizontal frame 21 and the second horizontal frame 22 are filled with a first support plate 71.

[0034] The planar frame 3 is provided with a second passage door 62 at a position corresponding to the first horizontal frame 21 and the second horizontal frame 22.

[0035] Except for the second passage door 62, the planar frame 3 is filled with a second support plate 72.

[0036] In practical work, the first support plate 71 is laid on the first horizontal frame 21 and the second horizontal frame 22 (except for the first passage door 61) to form a horizontal operating bearing surface for operators to stand and place tools in a horizontal state of the platform; The first horizontal frame 21 and the second horizontal frame 22 are provided with a first passage door 61, which serves as a passage between the side frame and the plane frame 3. It can be opened / closed to realize the switching between different operating surfaces. The second support plate 72 is laid on the planar frame 3 (except for the second passage door 62), and combined with the rigid structure of the planar frame 3 to form an auxiliary operating surface perpendicular to the side frame direction, expanding the operating range (such as side operation close to the arrow wall). The planar frame 3 is provided with a second passage door 62 at the position corresponding to the first horizontal frame 21 and the second horizontal frame 22, which serves as an access passage in the upright state. It can be opened / closed to facilitate the operator to move or go up and down the platform within the horizontal frame area.

[0037] In this example, the first support plate 71 and the second support plate 72 form continuous and complete bearing surfaces in the non-channel areas of the horizontal frame and the planar frame 3, respectively, replacing the hollow areas of the simple frame structure. This allows operators to stand directly on the first support plate 71 in the horizontal position and to work close to the side of the arrow wall using the second support plate 72 in the upright position, without the need for additional temporary footboards or supports. This solves the problems of unstable frame structure and easy tool drop, while providing a stable support surface for tool placement and temporary equipment installation, significantly improving operational convenience.

[0038] The support plate moves synchronously with the platform, maintaining a stable relative position with the arrow wall in both states, ensuring consistent operational standards and reducing operational adaptation costs caused by platform switching.

[0039] The first passageway door 61 and the second passageway door 62, through their opening / closing design, enable seamless passage between the horizontal frame and the planar frame 3: In the horizontal state, operators can enter the planar frame 3 from the horizontal frame through the second passageway door 62 to work on the side or bottom of the arrow wall without having to move around the outside of the platform, reducing unnecessary movement; in the upright state, operators can adjust their position within the horizontal frame area through the first passageway door 61. These passageway doors make switching between work areas more efficient, significantly reducing personnel movement time and improving overall work efficiency.

[0040] When the passageway door is closed, it forms a complete load-bearing surface together with the support plate, avoiding the risk of falling from the open areas of the frame; when open, only the necessary passage is exposed, and the edge of the passageway connects with the guardrail to form a safe transition area.

[0041] The presence of the support plate enhances the structural rigidity of the platform. Combined with the locking mechanism of the passage door, it can effectively prevent personnel from losing balance due to discontinuity of the bearing surface when the platform changes between horizontal and vertical states, thus solving the risk of falling into the air when the simple frame structure changes posture.

[0042] In an optional embodiment of the present invention, the above-mentioned service platform further includes: A first connecting frame 81 is horizontally disposed on the first side frame 11 opposite to the first horizontal frame 21; A first storage escalator 91 is rotatably connected to the first connecting frame 81; The second connecting frame 82 is arranged parallel to the first connecting frame 81 and opposite to the second horizontal frame 22, and is horizontally arranged on the second side frame 12; The second storage escalator 92 is rotatably connected to the second connecting frame 82.

[0043] Specifically, the aforementioned service platform also includes: A third guardrail 53 is provided on the first connecting frame 81 and the second connecting frame 82.

[0044] In specific work, the first connecting frame 81 and the second connecting frame 82 are respectively horizontally arranged on the first side frame 11 and the second side frame 12, and are arranged opposite to the first horizontal frame 21 and the second horizontal frame 22, serving as the installation base for storing the escalator, while also supporting the third guardrail 53, forming an auxiliary safety boundary. The first storage ladder 91 and the second storage ladder 92 are rotatably connected to the first connecting frame 81 and the second connecting frame 82 respectively (they can be folded / unfolded around the connection point). When unfolded, they serve as a passage for operators to go up and down the platform. When folded, they fit snugly against the frame and do not occupy extra space. The third guardrail 53 is installed on the two connecting frames and connects with the first guardrail 51 and the second guardrail 52 to form a closed protection in the area of ​​the connecting frames, especially when the escalator is being stored, to prevent people from falling from the edge of the connecting frames.

[0045] In this example, the first and second storage escalators are connected by a rotating mechanism to achieve flexible folding and unfolding: when unfolded in the horizontal state, they can directly connect to the ground, making it convenient for people to quickly get on and off the platform; during the erection process, they are folded to fit the frame, avoiding collisions with the ground or other equipment; if temporary access is needed when in the erected state, they can be unfolded again, eliminating the need to build additional passageways and solving the problem of platform accessibility in both horizontal and erected states, reducing the time cost for people to get on and off the platform, and improving the continuity of operations.

[0046] When not in use, the storage escalator can be completely retracted into the connecting frame without taking up extra space. It is also integrated with the overall structure of the platform and will not collide with other equipment when rotating synchronously with the platform. It is especially suitable for scenarios with dense equipment and limited space, such as rocket assembly workshops and launch sites, reducing the complexity of site layout.

[0047] In an optional embodiment of the present invention, the first side frame 11 and the second side frame 12 are rectangular support frames. The first horizontal frame 21 and the second horizontal frame 22 are triangular support frames.

[0048] In this example, the rectangle has a symmetrical right-angled side structure, which can form a regular vertical support surface when arranged vertically, making it easy to connect vertically with the horizontal frame and the planar frame 3. At the same time, it provides a flat and continuous fixing surface for the first fixing plate 41 and the second fixing plate 42, ensuring the rigidity and stability of the connection with the erecting frame.

[0049] The core function of the side frame is to bear the weight of the horizontal frame and the planar frame 3, and to transmit torque synchronously with the erecting frame. The rectangular structure has a uniformly distributed border, which can evenly transfer the load along the vertical frame to the erecting frame and avoid local stress concentration. At the same time, the hollow area inside the rectangle can reserve space for pipeline layout, or provide redundant space for operators to move sideways in the erecting state, thereby improving functionality.

[0050] Triangles possess geometric stability and are less prone to warping or deformation when subjected to vertical loads or lateral forces, exhibiting structural stiffness far exceeding that of rectangles.

[0051] The horizontal frame is the main load-bearing structure for operators to stand on and place tools, especially when the platform is horizontal, it must bear all vertical loads. During the erection process, the horizontal frame will gradually turn to an inclined state, bearing lateral force. The stability of the triangular structure ensures that the frame maintains its shape stability in both states, avoiding loosening of the support plate 71 or jamming of the passage door 61 due to deformation, while also reducing the frame's own vibration, indirectly ensuring the assembly accuracy of the rocket wall.

[0052] This utility model service platform, through its integrated design, allows for a single platform to adapt to both horizontal and vertical rocket wall configurations, reducing manufacturing costs and material consumption, saving space, and avoiding the time-consuming positioning and posture deviations associated with two platform transfers, thus ensuring the structural integrity of the rocket wall. The support plate and access door form a continuous load-bearing surface, eliminating instability and the risk of missteps, enabling seamless switching between work areas and improving efficiency. The foldable storage ladder saves space and avoids interference, while the third guardrail (53) provides a comprehensive protective system with no blind spots. The rectangular side frame ensures vertical support rigidity and connection precision, while the triangular horizontal frame enhances load-bearing capacity and resistance to deformation, adapting to high-precision operations. The overall structure balances safety, efficiency, and low cost, fully meeting the requirements of all working conditions for rocket wall assembly.
