Description

Technical Field

[0001] The present invention relates to the field of storage and long-distance transportation fastening for solid rocket support vehicles, and particularly to a portable transportation box for rocket support vehicles. Background Art

[0002] In the field of space engineering, rocket launch platform vehicles (rocket support vehicles) play a crucial role. The main function of rocket support vehicles is to provide stable support for the rocket body during the rocket general assembly and test stage. The importance of this support function cannot be ignored, because in the entire rocket general assembly process, each link is closely connected and the precision requirements are extremely high. The performance of rocket support vehicles is directly related to whether the subsequent rocket body general assembly and docking work can be carried out smoothly and accurately. If there are quality problems with rocket support vehicles, such as insufficient support stability or unqualified structural precision, then during the rocket body general assembly and docking, the position of the rocket body may deviate, affecting the connection and cooperation between 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 rocket support vehicles are one of the key factors to ensure the quality of rocket general assembly.

[0003] However, current rocket support vehicles face many challenges in the transportation link. When long-distance transportation is required, there is no dedicated packaging equipment designed for them. The current packaging method is extremely simple, only wrapping the vehicle with felt or plastic cloth. Although felt has certain buffering performance, its protection ability is limited, and it is easy to adsorb dust and moisture, which may cause corrosion to the vehicle surface after long-term use. Plastic cloth mainly plays a waterproof role, and its effect on preventing physical damage such as bumps is not ideal. In terms of fastening, the vehicle is mainly fixed by steel wire ropes. However, this fastening method has obvious drawbacks. During transportation, due to the bumps and vibrations of the vehicle during driving, or the vibrations of the train on the track, the vehicle is very easy to collide with other surrounding items. Once the vehicle is damaged, the integrity and precision of its structure will be affected, and the subsequent rocket body general assembly and test work may not be able to be carried out normally, which will not only delay the rocket development progress, but also increase additional maintenance costs and time costs. Therefore, there is an urgent need to develop a tooling that can not only facilitate the transportation of rocket support vehicles, but also provide effective protection for the vehicles and reduce the risk of damage during transportation.

[0004] At present, in the actual situation of the space launch site, there is still a lack of a dedicated rocket gantry vehicle transportation device. When conducting long-distance transportation, the gantry is usually directly fastened with steel wire ropes. This simple and crude method has many inconveniences. For example, in the transportation compartments of trains or trucks, due to the lack of a specially adapted transportation device, it is very difficult to place the gantry scientifically and reasonably. This not only may waste transportation space but also affect the load balance of the vehicle. Moreover, relying solely on steel wire ropes for fastening, the gantry is prone to shaking and displacement during transportation, further increasing the possibility of being knocked and damaged. All these problems highlight the urgency and necessity of developing a dedicated rocket gantry vehicle transportation device.

[0010] Purpose of the Invention: To provide a more effective portable transportation box for rocket gantries. The specific purpose can be seen in the multiple substantial technical effects in the specific implementation part.

[0011] To achieve the above object, the present invention adopts the following technical solutions:

[0013] Two groups of tracks 4 are arranged on the bottom wall 9 of the housing 1;

[0014] Lifting points are arranged above the housing 1;

[0015] One side of the track 4 is fixed by a fixing structure 7. The fixing structure 7 can fix the track 4 on the bottom wall 9 through a fixing bolt 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 a fixing plate 122 through a first hinge shaft 121, and a second hinge shaft 123 is hinged on the fixing plate;

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

[0019] The auxiliary multi-purpose track 5 has a structure with a flat bottom surface and an inclined surface above.

[0020] A further technical solution of the present invention is that two outward-opening doors are provided on both sides of the housing 1, and there are two lifting points at each of the four upper vertices of the packaging box. The lifting points are used for lifting the packaging box and fastening it on the train.

[0021] A further technical solution of the present invention is that both tracks 4 are steel rails, the distance between the steel rails is 1.435 meters, one side of the steel rail is 30 centimeters away from the side of the packaging box, and the other side is 50 centimeters away from the side of the packaging box.

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

[0023] A further technical solution of the present invention is that the bottom of the auxiliary multi-purpose track can be close to the surface of the track after being folded up.

[0024] A further technical solution of the present invention is that the steel rail and the auxiliary multi-purpose track 5 have the same width.

[0025] A further technical solution of the present invention is that the transport box has a basic skeleton made of steel structural parts, and the outer layer uses sheet metal parts as the skin, adopting a mature container design, with an openable lid at the front and rear ends; four embedded lifting points are designed at the four corners of the top of the transport box for the lifting of the transport box.

[0027] A further technical solution of the present invention is that the transport box is used to transport the rocket launcher vehicle, and the track width of the rocket launcher vehicle is the width of the Chinese standard railway track.

[0028] The present invention adopting the above technical solutions has the following beneficial effects compared with the prior art:

[0029] 1. The design concept pursues simplicity and clarity, and the operation process strives to be convenient and easy to understand. For the loading processes of the solid rocket full rocket launcher vehicle, the four-stage launcher vehicle, and the fairing assembly launcher vehicle, we have conducted in-depth thinking and careful design. This series of launcher vehicle loading schemes mainly focus on the space occupation problem during transportation, the complexity of the fastening method, and the length of time required for fastening. Through our innovative design, we have successfully solved the problems of excessive space occupation, cumbersome fastening methods, and long fastening time of the launcher vehicle during transportation. This not only significantly reduces the time spent by personnel in the overall loading and transportation process, but also improves the transportation efficiency, ensuring the safety and reliability of the transportation process.

[0030] 2. It has a wide range of applications and the production process is simple and easy. The transport box we designed, while fully considering the manufacturing cost, draws on the mature container technology in operation and makes corresponding improvements and optimizations. This improved transport box can not only continue to be used after being transported and transferred to the destination, but also can be used as a temporary storage location for materials and equipment. This design greatly reduces the quantity of materials stored in the factory building and also has the function of being used under field conditions. Through this multi-functional design, we not only improve the transportation efficiency of materials, but also save additional storage space and costs for users, making the entire material management process more efficient and economical.
