Description

Rocket-mounted portable transport box Technical Field

[0001] This utility model relates to the field of storage and long-distance transportation and securing of solid rocket support frame vehicles, and particularly to portable transport boxes for rocket support frame vehicles. Background Technology

[0002] In the field of aerospace engineering, rocket launch platform vehicles (rocket launchers) play a crucial role. The primary function of a rocket launcher is to provide stable support for the rocket body during the final assembly and testing phase. The importance of this support cannot be overlooked, as all stages of the rocket assembly process are closely interconnected and require extremely high precision. The performance of the rocket launcher directly affects the smooth and accurate execution of subsequent rocket body assembly and docking. If the rocket launcher has quality problems, such as insufficient support stability or substandard structural precision, then during rocket body assembly and docking, it may lead to deviations in the rocket's position, affecting the connection and fit between various rocket components, and thus posing a potential threat to the overall performance of the rocket and the safety of subsequent launches. Therefore, the quality and performance of the rocket launcher are among the key factors ensuring the quality of rocket assembly.

[0003] However, current rocket carriers face numerous challenges during transportation. There is no specially designed packaging equipment for long-distance transport. Current packaging methods are extremely simple, merely wrapping the carrier with felt or plastic sheeting. While felt offers some cushioning, its protective capabilities are limited, and it easily absorbs dust and moisture, potentially corroding the carrier's surface after prolonged use. Plastic sheeting primarily serves a waterproof function, but its effectiveness in preventing physical damage such as impacts is unsatisfactory. For securing the carrier, steel wire ropes are mainly used. However, this method has significant drawbacks. During transport, the carrier is easily damaged by the vehicle's movement and vibrations, or by the train's movement on the tracks, causing it to collide with surrounding objects. Damage to the carrier affects its structural integrity and precision, potentially hindering subsequent rocket assembly and testing, delaying rocket development, and increasing maintenance and time costs. Therefore, there is an urgent need to develop a tooling system that facilitates the transportation of rocket carriers while providing effective protection to reduce the risk of damage during transport.

[0004] Currently, dedicated rocket carrier transport devices are still lacking in the actual conditions of space launch sites. For long-distance transport, the carrier is typically secured directly with steel cables. This simplistic and crude method has many inconveniences. For example, within the transport compartments of trains or trucks, without specialized transport equipment, it is difficult to position the carrier scientifically and rationally, potentially wasting transport space and affecting the vehicle's load balance. Moreover, relying solely on steel cables for securing the carrier makes it prone to swaying and displacement during transport, further increasing the possibility of collisions and damage. All these problems highlight the urgency and necessity of developing a dedicated rocket carrier transport device.

[0015] One side of the track 4 is fixed to the bottom wall 9 by a fixing structure 7, which is fixed to the bottom wall 9 by fixing bolts 10.

[0016] The end of the fixing bolt 10 can be pressed into the pressing groove 6 of the track 4;

[0017] The end of the track 4 is hinged to the fixing plate 122 via the first hinge shaft 121, and the fixing plate is hinged to the second hinge shaft 123.

[0018] The second hinge shaft 123 is hinged to the auxiliary multi-purpose track 5;

[0022] A further technical solution of this utility model is that the fixing structure 7 is an inverted U-shaped ring structure.

[0023] A further technical solution of this utility model is that, after the auxiliary multi-purpose track is folded up, its bottom can be close to the surface of the track.

[0024] A further technical solution of this utility model is that the width of the steel rail and the auxiliary multi-purpose track 5 are the same.

[0025] A further technical solution of this utility model is that the transport box uses steel structural components as the basic skeleton and sheet metal components as the outer skin. It adopts a mature container design and is designed to be openable at the front and rear ends.

Through our innovative design, we successfully solved the problems of excessive space occupation, cumbersome fastening methods, and excessively long fastening times during transportation. This not only significantly reduces the time spent by personnel during the overall loading and transportation process but also improves transportation efficiency and ensures the safety and reliability of the transportation process.

[0030] 2. Wide range of applications and simple production process. Our designed transport container, while fully considering manufacturing costs, draws on mature container technology and makes corresponding improvements and optimizations. This improved transport container can not only be used after being transferred to its destination, but also serve as a temporary storage location for materials and equipment. This design significantly reduces the amount of materials stored in the factory, while also possessing the functionality for use in field conditions. Through this multi-functional design, we not only improve the efficiency of material transportation, but also save users additional storage space and costs, making the entire material management process more efficient and economical.

[0050] Design of rocket carrier transport container

[0051] The rocket transport container adopts a standard shipping container design, and its length is determined by the number of parking racks. The following diagram illustrates the parking of the rocket's fourth-stage and fairing racks as an example.

[0052] The packaging box is 6 meters long, 2.3 meters wide, and 2 meters high. It has two outward-opening doors on both sides and two lifting points at each of the four top points.

[0053] Used for lifting packaging boxes and securing them on trains;

[0054] Two steel rails are installed at the bottom of the packaging box, with a distance of 1.435 meters between them. One rail is 30 centimeters from the edge of the packaging box, and the other is 50 centimeters from the edge. U-shaped rings are installed symmetrically on both sides for securing the vehicle after parking.

[0055] A blocking block is installed at the head of the rail to secure the vehicle's parking position. A track 1.435 meters wide and 1.8 meters high is installed on the other side of the packaging box, with the track able to contact the ground.

[0056] The angle between the rail and the ground is 2.5 degrees, which facilitates the movement of the vehicle on the rail. During transportation, the rail is erected and secured with tension straps.

[0057] The following is a further explanation:

[0058] In the first scenario, if the overall height of the carriage is higher than the ground, then the auxiliary multi-purpose track 5 can make up for this height difference. In the second scenario, once the rocket is mounted on the vehicle, the auxiliary multi-purpose track 5 can be folded up and stored away.

[0059] The purpose of this portable rocket carrier transport box design is to solve the problems of long securing time and cumbersome operation of solid rocket carriers during long-distance transportation. Its features include the following limitations:

Four embedded lifting points are designed at the four corners of the top of the transport container for lifting purposes.

[0066] 2. The transport box is equipped with two steel rails. The rail type is 50, the rail height is 152mm, the rail base width is 132mm, the rail head width is 70mm, the rail web width is 15.5mm, the bolt hole diameter is 31mm, and the rail length is 6000mm. A plug is installed on one end of the rail, and the other end is bolted with the same rail. The rail is 1800mm long.

[0067] 3. Install U-shaped rings on both sides inside the packaging, with a distance of 500mm between the U-shaped rings, for securing the vehicle inside the packaging box.

[0068] Modular expansions and improvements based on the portable rocket carrier transport container are all within the protection scope required by this device.

[0069] Example 2: As a further improvement, parallel solution, or optional independent solution, two outward-opening doors are opened on both sides of the shell 1, and two lifting points are placed at each of the four top vertices of the packaging box. These lifting points are used for lifting the packaging box and securing it on the train. The substantive technical effect and implementation process of this technical solution, i.e., its basic function, are as follows: it facilitates lifting and installation.

[0070] Example 3: As a further possible improvement, parallel solution, or optional independent solution, both tracks 4 are steel rails, with a distance of 1.435 meters between them. One rail is 30 centimeters away from the edge of the packaging box, and the other rail is 50 centimeters away from the edge of the packaging box.

[0071] Example 4: As a further improvement, parallel solution, or optional independent solution, the fixing structure 7 is an inverted U-shaped ring structure. The substantive technical effect and implementation process of the technical solution here, i.e., its basic function, are as follows: Similar fixing methods are all within the protection scope of this patent.

[0072] Example 5: As a further improvement, parallel solution, or optional independent solution, the bottom of the auxiliary multi-purpose track can be close to the surface of the track after being folded up.

[0073] Example 6: As a further improvement, parallel, or optional independent solution, the width of both the steel rail and the auxiliary multi-purpose track 5 is the same.

[0074] Example 7: As a further improvement, parallel, or optional independent solution, the transport container uses steel structural components as the basic skeleton and sheet metal components as the outer skin. It adopts a mature container design and is designed with openable lids at the front and rear ends. Four embedded lifting points are designed at the four corners of the top of the transport container for lifting the transport container.

[0075] The rail has a height of 152mm, a bottom width of 132mm, a head width of 70mm, a web width of 15.5mm, a bolt hole diameter of 31mm, and a length of 6000mm. A plug is installed at one end of the rail.

[0076] The transport container is used to transport the rocket carrier, and the track width of the rocket carrier is the same as that of Chinese standard train tracks.

[0077] This invention addresses the lack of a transport device for solid rocket carriers during long-distance transportation. Specifically, it solves the following three technical problems.

[0078] The main components are solid rocket launcher docking carriages and four-stage carriages, which meet the requirements for loading during long-distance transportation and facilitate fastening on trains, thereby reducing the time required for loading and fastening carriages.

[0079] This transport container can meet the loading capacity of all existing vehicles, shorten loading and securing time during long-distance transportation, and facilitate the control of the overall loading time.

[0080] This flat transport container has a simple structure, is easy to operate, and is convenient to use.

[0081] Innovatively, each of the above effects exists independently, yet a single structure can be used to combine the results.

[0082] It should be noted that the multiple modules in this patent are an integration of existing technology modules and do not involve any new modules. Even if some modules use programs, those programs are undoubtedly known programs.

[0083] It should be noted that the multiple solutions provided in this patent include their own basic solutions, which are independent of each other and do not restrict each other. However, they can also be combined with each other without conflict to achieve multiple effects.

[0084] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
