[0031] The features and exemplary embodiments of various aspects of the utility model will be described in detail below. In the detailed description below, many specific details are proposed in order to provide a comprehensive understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without the need for some of these specific details. The following description of the embodiment is only to provide a better understanding of the utility model by illustrating an example of the utility model. In the drawings and the following description, at least part of the known structures and technologies are not shown in order to avoid unnecessary ambiguity to the utility model; and, for clarity, the size of some structures may be exaggerated. In addition, the features, structures or characteristics described below may be combined in one or more embodiments in any suitable manner.

[0032] The purpose of the embodiment of the utility model is to provide a movable ground air supply structure to solve the influence of terrain and ground problems on ground pipelines in the prior art, and greatly improve the efficiency of pipeline adjustment before and after rocket launch.

[0033] like Figure 1 and Figure 2 As shown, a movable ground air supply structure includes: a steel frame body 1; an air supply pipeline 3, which is arranged on the steel frame body 1; a moving device 2, which is arranged at the bottom of the steel frame body 1 and is used to move the steel frame body 1; a fixing device 4, which is arranged on the steel frame body 1 and is used to fix the air supply pipeline 3 on the steel frame body 1.

[0034] In some embodiments, the steel frame body 1 is welded by angle steel and steel plate. The steel frame body 1 is formed by connecting the angle steel and steel plate by welding process, and the angle steel and steel plate are precisely spliced ​​and fixed together to form a solid structure.

[0035] In some embodiments, the steel frame body 1 includes two layers of steel frames, each layer of which forms a triangular truss structure. The steel frame body 1 is a two-layer structure, and each layer adopts a triangular truss design. The triangular shape of the triangular truss provides good stability and support capacity. This design enables the structure to disperse and transfer loads more effectively, thereby improving the strength and stability of the overall structure. The design of the steel frame body 1 is stable and firm. The structure has high stability and rigidity and can withstand various external forces and loads without deformation or damage.

[0036] The steel frame body 1 is a two-layer triangular truss structure. This design has many advantages:

[0037] The triangle is the most stable structure in terms of geometry. In engineering, the triangular truss structure can effectively disperse and transfer loads, thereby providing higher stability and rigidity. Therefore, the two-layer triangular truss structure can further enhance the overall stability.

[0038] Due to the high strength and rigidity of steel, this double-layer structure can withstand large amounts of load and external forces without being easily deformed or damaged.

[0039] Although the structure itself is rigid, due to its dual-layer design, it can be adjusted and optimized between the two layers to suit different engineering needs. For example, additional supports or connection points can be added between the two layers to enhance the strength or stability of specific parts of the structure.

[0040] The double-layer design can provide more space without significantly increasing the structure's footprint. This is particularly useful for applications that need to span a large space or require additional space.

[0041] Double-layer structures are generally easier to maintain and inspect than single-layer structures because the double-layer design provides more access points and space, making it easier for engineers and technicians to inspect various parts of the structure and make necessary repairs or replacements.

[0042] In some embodiments, the mobile device 2 includes a fixed universal wheel. A fixed universal wheel is installed at the lower part of the steel frame body 1, which can be fixed when the steel frame body 1 is moved to a specified position. A fixed universal wheel is a wheel with multi-directional rotation capability and can be locked or fixed in a specific position when needed. Such wheels are usually installed on mobile equipment or structures to provide flexibility when movement is required, while providing fixed support when stability is required. The main features of the fixed universal wheel include: the universal wheel can rotate freely within a range of 360 degrees, so that it can easily change direction and adapt to different mobile needs. This wheel is equipped with a locking mechanism, and when the equipment or structure needs to be fixed, the wheel can be fixed in a certain position by the locking mechanism to prevent it from moving. The universal wheel is usually designed with a strong load-bearing capacity to support the weight of the mobile equipment or structure. Due to frequent contact and friction with the ground, the fixed universal wheel is usually made of wear-resistant materials to ensure its service life and stability. Even on complex or uneven ground, the fixed universal wheel can provide good mobility and flexibility. Some advanced fixed universal wheels are also equipped with brakes or other safety devices to ensure that they can stop moving quickly when needed, increasing safety in use. In a movable rocket ground air supply structure, the use of fixed universal wheels can easily move the air supply structure to a designated position and firmly fix it before the rocket is launched to ensure the stability and safety of the air supply system.

[0043] In some embodiments, one or both ends of the gas supply pipeline 3 are connected to a pipeline connector 5. Both ends of the gas supply pipeline 3 are welded with pipeline connectors 5. This design has the following technical effects:

[0044] The design of the pipeline joint 5 enables the gas supply pipeline 3 to be conveniently connected to other pipelines or equipment. The pipeline joint 5 fixed by welding ensures the stability and reliability of the connection, and also simplifies the process of installation and disassembly.

[0045] The use of the pipeline connector 5 can increase the adaptability and flexibility of the entire gas supply system. According to actual needs, different types of pipeline connectors 5 can be selected to connect pipelines and equipment of different specifications or types, thereby meeting different gas supply requirements.

[0046] When the gas supply pipeline 3 or the equipment connected thereto needs maintenance or overhaul, the design of the pipeline joint 5 allows for convenient disassembly and reinstallation without requiring large-scale modification or adjustment of the entire gas supply structure.

[0047] The pipe joint 5 usually adopts precise manufacturing technology and high-quality sealing materials to ensure that it has good sealing performance, which can effectively prevent gas leakage and improve the safety and efficiency of the gas supply system.

[0048] The pipe joints 5 welded at both ends of the gas supply pipe 3 generally have excellent pressure resistance and temperature resistance. They can maintain stable connection and sealing performance under high pressure and high temperature environment to ensure the normal operation of the gas supply system.

[0049] The gas supply pipeline 3 can be adjusted in quantity and type according to the specific ground gas supply plan. Pipe joints 5 are welded at both ends of the gas supply pipeline 3, and the joint form can be changed according to needs.

[0050] In some embodiments, the pipe connector 5 is welded to one or both ends of the gas supply pipeline 3, and the specifications of the multiple pipe connectors 5 on the multiple gas supply pipelines 3 are different. The specifications of the pipe connector 5 include the following: Size: including the inner diameter, outer diameter, length, etc. of the pipe connector 5 to match the corresponding pipelines and equipment. Shape: The shape of the pipe connector 5 may vary depending on the connection method and application scenario, such as straight, elbow, tee, etc. Connection method: Such as threaded connection, clamp connection, quick connector connection, etc., different connection methods correspond to different specifications of the pipe connector 5. Material: The material of the pipe connector 5 may also vary depending on application requirements, such as stainless steel, copper, plastic, etc.

[0051] In some embodiments, the fixing device 4 may include: a U-shaped clamp, a round pipe clamp, a square pipe clamp, a bolt clamp or a spring clamp. Preferably, a U-shaped clamp 4 is installed on the steel frame body 1 to fix the gas supply pipeline 3 and prevent it from moving.

[0052] Specifically, the structure includes a steel frame body 1, a universal wheel can be fixed at the bottom of the steel frame body 1, and a gas supply pipeline 3. U-shaped clamps are installed on the steel frame body 1, and pipeline joints 5 are welded at both ends of the gas supply pipeline 3. The main body of the structure is a steel frame 1, which is welded by angle steel and steel plate, with a total of two layers, both of which are triangular truss structures, stable and firm, and can be adjusted according to the number of required gas supply pipelines 3. The two ends of the gas supply pipeline 3 (hard pipe) can be connected to the hose to connect the structure to the structure. The pipeline joint 5 is connected to the two ends of the gas supply pipeline 3 (hard pipe) and is used to connect with the hose or other hard pipes to realize the transmission of gas in the pipeline system. The hose is used as a flexible connection component between the pipeline joint 5 and other equipment or structures, which can adapt to different installation angles and distances and has a certain bending and expansion capacity. The hose is connected to the pipeline joint 5 by threaded connection or clamp connection. In the threaded connection method, the pipeline joint 5 is provided with an internal thread or an external thread, and the end of the hose is provided with a corresponding external thread or internal thread. The hose and the pipe connector 5 are tightly connected by screwing the threads. This connection method has good sealing and detachability. In the clamp connection method, a clamp is installed at the end of the hose. After the hose is put on the pipe connector 5, the hose and the pipe connector 5 are tightly fitted by tightening the clamp. The clamp is generally made of metal or plastic material and has certain elasticity and corrosion resistance.

[0053] It can be adjusted according to the number of required gas supply pipelines 3, indicating that the design of the steel frame main structure has a certain flexibility, and the configuration or layout of the steel frame main structure can be adjusted according to the number of actually required gas supply pipelines 3.

[0054] The hose has a high bending ability and can adapt to different installation angles and distances, making it convenient to connect two rigid pipe structures that are not in the same straight line. Since the hose can bend and stretch, it is easier to adjust the pipeline layout during installation, reducing the difficulty of installation. At the same time, the hose is also easier to disassemble and reinstall during maintenance and replacement of parts. The hose has certain elasticity and damping characteristics, which can absorb vibration and noise in the pipeline system and improve the stability and quietness of the system. The rigid pipe may expand and contract when the temperature changes, and the hose can better adapt to this temperature change and avoid the stress caused by the resulting damage to the pipeline system. In some cases, using a hose as a connector can reduce safety hazards caused by rigid pipe breakage or connection failure. In short, by connecting the hose at both ends of the air supply pipeline 3 (rigid pipe), a flexible, safe and reliable connection between the various components of the pipeline system can be achieved, improving the performance and stability of the entire system.

[0055] Flying sand and rocks in the environment can also cause wear and tear on the gas supply pipeline, and rain and water accumulation due to weather conditions can also affect the gas transportation in the pipeline. The ground gas supply pipeline equipment of launch vehicles in the prior art cannot solve this problem. In this embodiment, since the gas supply structure is movable, it can be moved to a safer or sheltered place before the forecast of severe weather, thereby reducing the direct impact of flying sand and rocks and rain on the gas supply pipeline. The steel frame body is welded by angle steel and steel plates to form a stable triangular truss structure, which can provide a certain degree of protection for the gas supply pipeline and reduce the risk of direct exposure to harsh environments. U-shaped clamps or other fixing devices can ensure that the gas supply pipeline can remain in the proper position even in severe weather, reducing displacement and wear caused by wind or water flow.

[0056] In a further embodiment, in order to provide a more direct solution to the problems of flying sand and rocks and rainwater accumulation, the following improved technical solutions can also be adopted: adding a protective cover or sheath to the pipeline to prevent flying sand and rocks from directly contacting the pipeline surface; designing a drainage system for the pipeline to ensure that accumulated water can be effectively removed even in rainfall to prevent water from affecting gas delivery; using wear-resistant materials or coatings to manufacture the gas supply pipeline to improve its ability to resist wear caused by flying sand and rocks.

[0057] In a further embodiment, adding a protective cover or sheath to the gas supply pipeline specifically includes: custom-designing the protective cover or sheath according to the shape and size of the gas supply pipeline to ensure that it can be tightly fitted on the outside of the pipeline without leaving any gaps. Select materials with high strength, wear resistance, and good weather resistance, such as wear-resistant plastics, rubber, or metal alloys, to ensure that the protective cover or sheath can remain intact for a long time in harsh environments. The protective cover or sheath can be installed on the pipeline by sliding, snap-on, or screw fixing, and it should be ensured that the installation is firm and not easy to fall off. The main function of the protective cover or sheath is to prevent flying sand and rocks from directly contacting the surface of the gas supply pipeline, thereby avoiding damage to the gas supply pipeline due to impact or friction. At the same time, it can also play a certain degree of waterproofing role, reducing the impact of rainfall on the gas supply pipeline.

[0058] In a further embodiment, the use of wear-resistant materials or coatings to manufacture the gas supply pipeline specifically includes: when manufacturing the gas supply pipeline, materials that are inherently wear-resistant can be selected, such as certain special plastics, alloy steels, etc. For the pipeline that has been manufactured, a layer of wear-resistant coating can be coated on its surface. This coating is usually composed of wear-resistant materials such as ceramic particles and silicon carbide, and is attached to the surface of the pipeline by spraying, dipping or electroplating. In addition to the coating, the hardness and wear resistance of the pipeline material can be further improved by strengthening treatment processes such as heat treatment and surface hardening. The use of wear-resistant materials or coatings can effectively improve the ability of the pipeline to resist wear caused by flying sand and rocks, and extend its service life. At the same time, some coatings also have additional functions such as corrosion resistance and waterproofing, which can more comprehensively protect the pipeline from the invasion of harsh environments.

[0059] The above two technical solutions can be used in combination to provide more comprehensive and direct protection for the gas supply pipeline, ensuring its safe and stable operation in harsh environments such as flying sand and rocks and rain and water accumulation.

[0060] The beneficial technical effects produced by the utility model are as follows:

[0061] Most existing rocket ground air supply devices are laid on the ground, which has high construction costs and long production cycles. The movable ground air supply structure can greatly reduce production costs, shorten production cycles, reduce test frequency and improve launch efficiency, which is beneficial to commercial rocket operations.

[0062] The movable ground air supply structure can be moved according to the actual situation on site, which is beneficial for the preparation before rocket launch and the withdrawal after launch.

[0063] The main structure of the movable ground air supply structure is made of shelf products, which is convenient for material selection and manufacturing. Shelf products refer to standardized components or assemblies that are already available on the market and are used to build various structures. There are several benefits to using shelf products: convenient material selection, because shelf products are usually produced in a standardized manner, it is easier to choose suitable materials, and there is no need to design and manufacture from scratch. Simplify the manufacturing process, using shelf products can reduce many custom processing and manufacturing steps, thereby simplifying the entire production process and saving time and costs. Improve reliability, shelf products are usually subject to strict quality control and testing, so using them can improve the reliability and stability of the entire structure to a certain extent. Convenient maintenance and upgrades, if the structure needs to be maintained or upgraded in the future, using shelf products can make it easier to find replacement parts or expand.

[0064] If the number and size of pipelines need to be adjusted, only the size of the steel plates and angles needs to be adjusted. The adjustment of the size of the steel plates and angles includes the following aspects: Changing the length, width or thickness of the steel plates or angles to accommodate different numbers or sizes of gas supply pipelines. Adjusting the shape or structure of the steel plates or angles to better support and fix the gas supply pipelines. Increasing or decreasing the number of steel plates or angles to match the number and layout of gas supply pipelines. The advantage of this design idea is that by simply adjusting the size of the steel plates and angles, the requirements of different numbers and sizes of pipelines can be accommodated, making the structure more flexible and changeable. Adjusting the size of the steel plates and angles is relatively easy and does not require large-scale changes or redesign of the entire structure. Since only local adjustments are required instead of complete remanufacturing, costs and time can be saved while meeting specific needs.
