[0017] As mentioned in the background technology, the problems existing in the prior art are not solved. This embodiment provides a support structure for a rocket launch box, including: Support body 1; Folding components 2, two groups of folding components 2 are arranged on the supporting body 1 along the first horizontal direction, and each group of two folding components 2 are symmetrically arranged on both sides of the supporting body 1 along the second horizontal direction, and the second horizontal direction is perpendicular to the first horizontal direction; the folding components 2 can be unfolded to the side away from the supporting body 1 or folded to the side close to the supporting body 1; The first telescopic member 3 is arranged on the folding component 2 and can be moved in the horizontal direction to get closer to or away from the supporting body 1 under the drive of the folding component 2; the first telescopic member 3 can be telescoped in the vertical direction to adjust the distance between the supporting body 1 and the ground.

The support body 1 includes a main frame, and a plurality of groups of reinforcing ribs are welded on the main frame to improve the overall strength of the support body 1. The upper surface of the support body 1 is machined to ensure that it fits the rocket; the four folding components 2 are respectively arranged at positions close to the four corners of the support body 1, and the first telescopic member 3 is the main support load-bearing leg of the support structure, which adopts the existing technology. A hydraulic cylinder is provided on the container assembly 5, and a movable door is provided on the container assembly 5 for the folding assembly 2 and the first telescopic member 3 to pass through. When the folding assembly 2 is in the folded state, the first telescopic member 3 in the contracted state can be close to the supporting body 1, and the supporting structure is located inside the container assembly 5 as a whole, reducing the space occupied by the supporting structure, which is convenient for loading and transportation. After the folding assembly 2 is unfolded, the first telescopic member 3 can extend out of the container assembly 5 and be located outside the vehicle in the vertical direction. After the first telescopic member 3 is extended, it supports the ground so that the supporting body 1 rises in the vertical direction and separates from the vehicle to complete unloading; at the same time, the four first telescopic members 3 are controlled to extend and retract to adjust the posture of the supporting body 1 so that it is in a horizontal state.

[0019] By arranging the first telescopic part 3 on the supporting body 1, the folding assembly 2 makes the first telescopic part 3 close to the supporting body 1 after being retracted, occupying a small space and being convenient for transportation; after the folding assembly 2 is unfolded, the four first telescopic parts 3 are synchronously extended to support the ground to drive the supporting body 1 to rise, so that it is separated from the vehicle, and then the unloading can be completed without lifting; at the same time, the four first telescopic parts 3 are respectively controlled to extend and retract to adjust the supporting body 1 to make it reach a horizontal state, which is beneficial to improving the overall stability and ease of use of the rocket launch box.

[0020] In a preferred embodiment, the folding component 2 includes an extension leg 21 and a second telescopic member 22, one end of the extension leg 21 is rotatably connected to the support body 1, and the other end of the extension leg 21 is fixed to the first telescopic member 3; the two ends of the second telescopic member 22 are respectively rotatably connected to the support body 1 and the extension leg 21.

[0026] In a preferred embodiment, inclination sensors 4 are respectively provided at both ends of the support body 1 along the first horizontal direction.

[0027] like Figure 2 As shown, two inclination sensors 4 are respectively installed at both ends of the length direction of the support body 1. The overall horizontality of the support body 1 can be calculated by the difference between the two inclination sensors 4, and then the support body 1 is adjusted to a horizontal state through the four first telescopic members 3.

[0028] In a preferred embodiment, a mounting hole is provided on the extension leg 21, and the first telescopic member 3 includes a first fixed section and a first telescopic section. The first fixed section is inserted into the mounting hole, and a support plate 31 is provided at one end of the first telescopic section away from the fixed section.

[0029] like Figure 4-8 As shown, a mounting hole extending in the vertical direction is opened on one end of the extension leg 21 away from the rotating hole, and the first telescopic member 3 is fixed to the extension leg 21 through the mounting hole. The first fixed section and the first telescopic section are respectively the cylinder and piston rod of the first telescopic member 3. The cylinder of the first telescopic member 3 is fixed in the mounting hole, and a circular support plate 31 is fixed to the free end of its piston rod. The support plate 31 is used to disperse the pressure of the first telescopic member 3 on the ground to keep it stably supported.

[0030] In a preferred embodiment, the second telescopic member 22 includes a second fixed section and a second telescopic section, the second fixed section is rotatably connected to the support body 1 via a second pin shaft 221 , and the second telescopic section is rotatably connected to the extended leg 21 .

The first mounting seat 12 is used for the mounting support of the second telescopic member 22, and the cylinder of the second telescopic member 22 is rotatably connected to the first mounting seat 12 through a second pin shaft 221; one side of two symmetrically arranged extended legs 21 is provided with a second mounting seat 211, and the piston rod of the corresponding second telescopic member 22 is also rotatably connected to the second mounting seat 211 through a second pin shaft 221; the top of the other two symmetrically arranged extended legs 21 is provided with a mounting shaft 212, and the piston rod of the corresponding second telescopic member 22 is rotatably connected to the mounting shaft 212.

[0032] Working principle: During initial transportation, the folding component 2 makes the retracted first telescopic member 3 close to the supporting body 1, and the supporting structure is located in the container component 5 as a whole. After arriving at the target location, the four second telescopic members 22 are extended at the same time, driving the corresponding extended legs 21 to rotate relative to the supporting body 1 until it rotates 90 degrees. At this time, the projections of the four first telescopic members 3 in the vertical direction are all located outside the vehicle. The synchronous extension of the four first telescopic members 3 can support the ground and drive the supporting body 1 to rise, so that the supporting body 1 is separated from the vehicle, and the vehicle starts and leaves to complete the unloading. After unloading, the four telescopic members are respectively controlled to extend and retract according to the values ​​of the two inclination sensors 4 to adjust the posture of the supporting body 1, so that the supporting body 1 finally reaches a horizontal state.
