Detailed Description
Features and exemplary embodiments of various aspects of the utility model are described in detail below. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the utility model. It will be apparent, however, to one skilled in the art that the present utility model may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the utility model by showing examples of the utility model. In the drawings and the following description, at least some well-known structures and techniques have not been shown in order to avoid unnecessarily obscuring the present utility model, and the dimensions of some of the structures may be exaggerated for clarity. Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
The embodiment of the utility model aims to provide a movable ground air supply structure, which solves the problems of the prior art such as the influence of the terrain and the ground on a ground pipeline, and greatly improves the pipeline adjustment efficiency before and after rocket launching.
As shown in fig. 1 and 2, the movable ground air supply structure comprises a steel frame body 1, an air supply pipeline 3 arranged on the steel frame body 1, a moving device 2 arranged at the bottom of the steel frame body 1 and used for moving the steel frame body 1, and a fixing device 4 arranged on the steel frame body 1 and used for fixing the air supply pipeline 3 on the steel frame body 1.
In some embodiments, the steel frame body 1 is welded from angle steel and steel plate. The steel frame body 1 is formed by connecting angle steel and steel plates through a welding process, and the angle steel and the steel plates are precisely spliced and fixed together to form a firm structure.
In some embodiments, the steel frame body 1 comprises two layers of steel frames, each forming 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. This design allows the structure to more effectively distribute and transfer loads, thereby improving the strength and stability of the overall structure. The steel frame body 1 is designed to be stable and firm, has high stability and rigidity, and can bear various external forces and loads without deformation or damage.
The steel frame body 1 is a two-layered triangular truss structure, and this design has various advantages:
Triangles are geometrically the most stable structures, and triangular truss structures are able to efficiently distribute and transfer loads during engineering, providing higher stability and stiffness. Thus, the two-layered triangular truss structure may further enhance overall stability.
Due to the high strength and rigidity of the steel, the double-layer structure can bear a large amount of load and external force, and is not easy to deform or damage.
Although the structure itself is rigid, due to its double layer design, adjustments and optimizations can be made between the two layers to accommodate different engineering requirements. For example, additional supports or connection points may be added between the two layers to enhance the strength or stability of specific portions of the structure.
The double layer design may provide more space without significantly increasing the structural footprint. This is particularly useful for application scenarios that require spanning a large space or require additional space.
The double layer structure is generally easier to maintain and inspect than the single layer structure. Because the double layer design provides more access points and space, engineers and technicians can more easily inspect various parts of the structure and perform necessary repair or replacement work.
In some embodiments, the mobile device 2 comprises a fixable universal wheel. The lower part of the steel frame main body 1 is provided with fixable universal wheels, and the steel frame main body 1 can be fixed when moving to a prescribed position. A fixable universal wheel is a wheel that has multi-directional turning capability and can be locked or fixed in a specific position when desired. Such wheels are typically mounted on a mobile device or structure to provide flexibility when movement is desired, while providing fixed support when stability is desired. The fixable universal wheel is mainly characterized in that the universal wheel can freely rotate within a 360-degree range, so that the direction of the universal wheel can be easily changed, and different movement requirements can be met. Such wheels are equipped with a locking mechanism by which the wheel can be fixed in a certain position against movement when a fixture or structure is desired. Universal wheels are typically designed with a strong load bearing capacity to support the weight of the mobile device or structure. Because of the frequent contact and friction with the ground, fixable universal wheels are often made using wear resistant materials to ensure their service life and stability. Fixable universal wheels provide better mobility and flexibility even on complex or uneven ground. Some advanced fixable universal wheels are also equipped with brakes or other safety devices to ensure rapid stopping of movement when needed, increasing safety in use. In the movable rocket ground air supply structure, the fixable universal wheels can be used for conveniently moving the air supply structure to a designated position and firmly fixing the air supply structure before rocket launching so as to ensure the stability and safety of an air supply system.
In some embodiments, a pipe joint 5 is connected to one or both ends of the gas supply pipe 3. The two ends of the air supply pipeline 3 are welded with pipeline joints 5, and the design has the following technical effects:
The design of the line connection 5 allows the gas supply line 3 to be connected easily to other lines or devices. The pipe joint 5 fixed by welding ensures the stability and reliability of the connection, and simplifies the process of installation and disassembly.
The use of the pipe joint 5 may increase the flexibility and adaptability of the entire air 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, so that different air supply requirements are met.
When the air supply line 3 or the equipment to which it is connected requires maintenance or repair, the design of the line connection 5 can be easily disassembled and reinstalled without extensive modification or adjustment of the entire air supply structure.
The pipe joint 5 is usually manufactured with a precise manufacturing process and a high quality sealing material to ensure good sealing properties. Therefore, gas leakage can be effectively prevented, and the safety and efficiency of the gas supply system are improved.
The pipe joints 5 welded to both ends of the gas supply pipe 3 generally have excellent pressure and temperature resistance, and they can maintain stable connection and sealing properties under high pressure and high temperature environments, ensuring the normal operation of the gas supply system.
The air supply pipeline 3 can be adjusted in quantity and type according to a specific ground air supply scheme, pipeline connectors 5 are welded at two ends of the air supply pipeline 3, and the connector form can be changed according to requirements.
In some embodiments, the pipe joint 5 is welded at one or both ends of the air supply pipe 3, and specifications of the plurality of pipe joints 5 on the plurality of air supply pipes 3 are not the same. The specifications of the pipe joint 5 include dimensions including the inside diameter, outside diameter, length, etc. of the pipe joint 5 to match the corresponding piping and equipment. The shape of the pipe joint 5 may vary depending on the connection mode and the application, such as straight, bent, three-way, etc. The connection modes are threaded connection, clamp connection, quick joint connection and the like, and different connection modes correspond to different specifications of the pipeline joint 5. The material of the pipe joint 5 may also vary depending on the application requirements, such as stainless steel, copper, plastic, etc.
In some embodiments, the securing device 4 may comprise a U-shaped clamp, a round clamp, a square clamp, a bolt clamp, or a spring clamp. Preferably, the U-shaped clamp 4 is arranged on the steel frame main body 1, which is favorable for fixing the air supply pipeline 3 and preventing dislocation.
Specifically, the structure includes steelframe main part 1, sets up in the bottom fixable universal wheel of steelframe main part 1, and air feed pipeline 3 all installs U type clamp on the steelframe main part 1, and air feed pipeline 3's both ends all weld and have pipeline joint 5. The structural main body is a steel frame 1, is formed by welding angle steel and steel plates, has a triangular truss structure in two layers, is stable and firm, and can be adjusted according to the number of required air supply pipelines 3. The two ends of the air supply pipeline 3 (hard pipe) can be connected with hoses to connect the structures. The pipe joint 5 is connected to two ends of the gas supply pipe 3 (hard pipe) and is used for being connected with a hose or other hard pipes to realize the transmission of gas in a pipe system. The hose is used as a flexible connecting part between the connecting pipeline joint 5 and other equipment or structures, can adapt to different installation angles and distances, and has certain bending and stretching capabilities. The hose is connected to the pipe connection 5 by means of a screw connection or a clip connection. In the threaded connection, the line connection 5 is provided with an internal or external thread, while the hose end is provided with a corresponding external or internal thread. By screwing the threads, the tight connection of the hose and the pipeline joint 5 is realized. The connecting mode has good sealing performance and detachability. In the clip connection mode, a clip is installed at the end of the hose, and after the hose is sleeved on the pipe joint 5, the hose is tightly attached to the pipe joint 5 by fastening the clip. The clamp is generally made of metal or plastic materials, and has certain elasticity and corrosion resistance.
The number of the required air supply pipelines 3 can be adjusted, so that the design of the steel frame main body structure has certain flexibility, and the configuration or layout of the steel frame main body structure can be adjusted according to the number of the air supply pipelines 3 actually required.
The hose has higher bending capability, can adapt to different installation angles and distances, and is convenient to connect two hard tube structures which are not on the same straight line. Because the hose can be bent and telescopic, the pipeline layout can be more easily adjusted in the installation process, and the installation difficulty is reduced. At the same time, the hose is also easier to disassemble and reinstall during maintenance and replacement of the components. The hose has certain elasticity and damping characteristics, can absorb vibration and noise in a pipeline system, and improves the stability and quietness of the system. The hard tube may generate expansion and contraction phenomenon when the temperature changes, and the hose can adapt to the temperature changes better, so that the damage of the stress generated by the temperature changes to the pipeline system is avoided. In some cases, the use of hoses as connectors can reduce the safety hazards caused by broken or failed hard tubing. In short, flexible, safe and reliable connection between all parts of the pipeline system can be realized by connecting hoses at two ends of the air supply pipeline 3 (hard pipe), and the performance and stability of the whole system are improved
Because flying sand and stones in the environment also can cause abrasion to the air supply pipeline, and rainfall ponding can also influence the pipeline gas transportation due to weather reasons. The ground air supply pipeline equipment of the carrier rocket in the prior art cannot solve the problem. In this embodiment, since the air supply structure is removable, it can be moved to a safer or shielded location prior to severe weather forecast, thereby reducing the direct impact of flying sand and stones and rain on the air supply line. The steel frame main body is formed by welding angle steel and steel plates, and a stable triangular truss structure is formed, so that a certain degree of protection can be provided for the air supply pipeline, and the risk of direct exposure to severe environments is reduced. The U-shaped clip or other securing device ensures that the air supply line remains in place even in severe weather, reducing shifting and wear due to wind or water currents.
In a further embodiment, in order to provide a more direct solution to the problems of flying sand and water accumulation during rainfall, an improved solution may be provided by adding a protective cover or sheath to the pipeline to prevent the flying sand and water accumulation from directly contacting the pipeline surface, designing the drainage system of the pipeline to ensure that water accumulation can be effectively removed even during rainfall, preventing water from affecting gas delivery, and using a wear resistant material or coating to manufacture the gas supply pipeline to improve its resistance to the abrasion of flying sand and water accumulation.
In a further embodiment, adding a protective cover or sheath for the air supply line specifically includes custom designing the protective cover or sheath according to the shape and size of the air supply line to ensure a tight fit over the line without leaving gaps. Materials with high strength, wear resistance and good weather resistance, such as wear-resistant plastics, rubber or metal alloy, are selected to ensure that the protective cover or sheath can remain intact for a long time in severe environments. The protection cover or the sheath can be installed on the pipeline in a sliding type, a buckling type or screw fixing mode, and the like, so that firm installation and difficult falling off are ensured. The main function of the protective cover or the protective sleeve is to prevent flying sand and stones from directly contacting the surface of the air supply pipeline, so that the air supply pipeline is prevented from being damaged due to impact or friction. Meanwhile, the water-proof air supply pipeline can play a role in water prevention to a certain extent, and the influence of rainfall on the air supply pipeline is reduced.
In a further embodiment, the use of a wear resistant material or coating to manufacture the air supply line specifically includes the selection of materials that are inherently wear resistant, such as certain specialty plastics, alloy steels, etc. in manufacturing the air supply line. For the pipe which is already manufactured, a wear-resistant coating can be applied to the surface of the pipe. Such coatings are typically composed of wear resistant materials such as ceramic particles, silicon carbide, etc., and are applied to the pipe surfaces by spraying, dipping, or electroplating. In addition to the coating, the hardness and wear resistance of the pipe material may be further improved by a strengthening treatment process such as heat treatment, surface hardening, etc. The wear-resistant material or the coating can effectively improve the capability of the pipeline in resisting the flying sand and stone abrasion and prolong the service life of the pipeline. Meanwhile, some coatings have additional functions of corrosion resistance, water resistance and the like, and can more comprehensively protect pipelines from being damaged by severe environments.
The two technical schemes can be combined to provide more comprehensive and direct protection for the air supply pipeline, and ensure that the air supply pipeline can safely and stably run under severe environments such as flying sand, stone, rainfall and ponding.
The beneficial technical effects produced by the utility model are as follows:
Most of the existing rocket ground air supply devices adopt ground pavement, and have high construction cost and long period. The movable ground air supply structure can greatly reduce the production cost, shorten the production period, reduce the test frequency, improve the emission efficiency and is beneficial to the operation of commercial rockets.
The movable ground air supply structure can move according to the actual situation of the site, and is beneficial to preparation before rocket launching and withdrawal after rocket launching.
The structural main bodies of the movable ground air supply structure all adopt goods shelf products, so that materials are convenient to select and manufacture. Shelf products refer to components or assemblies that are already commercially available, standardized for use in constructing various structures. The use of shelf products has the advantage of facilitating material selection, as shelf products are typically produced in a standardized manner, so that it is easier to select the appropriate materials without the need to design and manufacture from scratch. The manufacturing process is simplified, and the number of custom processing and manufacturing steps can be reduced by using the shelf products, so that the whole production process is simplified, and the time and the cost are saved. With increased reliability, shelf products are often subjected to stringent quality control and testing, so their use can improve the reliability and stability of the overall structure to some extent. And the maintenance and the upgrading are convenient, and if the structure is required to be maintained or upgraded in the future, replacement parts can be more conveniently found or expanded by using the shelf products.
If the number and the size of the pipelines need to be adjusted, the sizes of the steel plates and the angle steel only need to be adjusted. The adjusting of the steel plate and the angle steel comprises the following steps of changing the length, the width or the thickness of the steel plate or the angle steel so as to adapt to different numbers or sizes of air supply pipelines. The shape or structure of the steel plate or angle steel is adjusted so as to better support and fix the air supply pipeline. The number of steel plates or angle steel is increased or decreased to match the number and layout of air supply pipelines. The design thought has the advantages that the pipeline requirements of different numbers and sizes can be met by simply adjusting the sizes of the steel plates and the angle steel, so that the structure is more flexible and changeable. The sizes of the steel plates and the angle steel are relatively easy to adjust, and the whole structure does not need to be changed or redesigned in a large scale. Cost and time are saved while meeting specific requirements because only partial adjustment is needed instead of complete remanufacturing.
