Protective clothing and protective method for railway transportation of large-diameter rocket body

Abstract

The invention provides protective clothing and a protective method for a large-diameter rocket body. The protective clothing comprises a plurality of segmented protective clothing bodies (1), an adhesive tape (2), a front protective end cover (3) and a rear protective end cover (4), the segmented protective clothing bodies (1) are sequentially arranged in the axial direction of a rocket body, the adhesive tape (2) is used for achieving axial connection of the segmented protective clothing bodies (1), and the front protective end cover (3) and the rear protective end cover (4) are installed on the axial end face of the rocket body. Protection of two end faces and fixing and locking of the two ends of the protective clothing in the rocket body transportation process are achieved, the segmented protective clothing (1) is provided with an inner skin (21), an outer skin (21), an inner core (22) and a tightening device (23), and the tightening device (23) is used for circumferential tightening of the protective clothing. The problems that a large-diameter carrier rocket cannot be normally transported by a railway due to over-limit railway transportation and the assembly efficiency of protective clothing is low are solved, safety protection of the large-diameter carrier rocket in the railway transportation process can be achieved, and the assembly efficiency of the protective clothing is improved.

Description

technical field [0001] The invention relates to the field of launch vehicle transportation, in particular to protective clothing and a protective method for large-diameter rocket body railway transportation. Background technique [0002] At present, small and medium-diameter rockets in China generally use Ω-type railway transport vehicles for railway transportation protection. Rockets with a diameter exceeding 3350mm cannot be transported in this way due to the requirements of railway transportation limits. With the increasing requirements for the carrying capacity of launch vehicles , the diameter of the launch vehicle has also increased. At present, the large-diameter launch vehicle can only be transported to the launch base by sea, which is costly and takes a long time. Therefore, the large-diameter launch vehicle body needs to be covered with protective clothing. To complete the rocket body rail transport mission. [0003] The length of the rocket body of the launch veh...

AI Technical Summary

Problems solved by technology

[0002] At present, small and medium-diameter rockets in China generally use Ω-shaped railway transport vehicles for railway transportation protection. Rockets with a diameter exceeding 3350mm cannot be transported in this way due to the railway transportation limit requirements. With the increasing requirements for the carrying capacity of launch vehicles , the diameter of the launch vehicle increases accordingly. At present, the large-diameter launch vehicle can only be transported to the launch base by sea, which is costly and takes a long time. Therefore, the large-diameter launch vehicle body needs to be covered with protective clothing. To complete the rocket body rail transport mission

[0003] The length of the rocket body of the launch vehicle is long, and the cost of covering it with a whole section of protective clothing is relatively high, and due to the heavy weight of the protective clothing itself, it cannot be assembled
