An ear seat is provided on the third platform section 24. One end of the second unfolding and folding push rod 272 is rotatably connected to the third platform section 24 through the ear seat on the third platform section 24; the other ends of the first unfolding and folding push rod 271 and the second unfolding and folding push rod 272 are both movably connected to the other end of the unfolding and folding transition frame 273 and are respectively located on both sides of the unfolding and folding transition frame 273. Motors 274 and hand wheels 275 are provided on both the first unfolding and folding push rod 271 and the second unfolding and folding push rod 272, and the hand wheel 275 is located on the motor 274. The first unfolding and folding push rod 271 and the second unfolding and folding push rod 272 are driven by the motor 274 to move, thereby driving the third platform section 24 to rotate, and further realizing the disconnection or splicing of the third platform section 24. In the embodiment of the present application, the power mode of the unfolding and folding mechanism 27 adopts a form of double-cylinder series drive. Usually, a single cylinder can meet the safety angle requirements for the unfolding and folding of the second platform section 23 or the third platform section 24. In the present application, the double-cylinder drive can improve the reliability of the action. When the drives of the first unfolding and folding push rod 271 and the second unfolding and folding push rod 272 fail, emergency manual operation can also be performed through the hand wheel 275. It should be noted that the platform unfolding and folding mechanism 27 can also achieve redundant backup by replacing the series motor with a double drive motor; or the drive can be realized by replacing the motor with an oil cylinder. The embodiment of the present application does not limit the drive form of the platform unfolding and folding mechanism 27; the first unfolding and folding push rod 271 and the second unfolding and folding push rod 272 include telescopic rods.

When the tooling module 2 is in a closed state, the retractable top cover movable part 2912 is in a flat state, and the flattened retractable top cover movable part 2912 presses the second sealing strip 2915. Since the part of the second sealing strip 2915 pasted on the retractable top cover fixing part 2911 extends beyond the retractable top cover fixing part 2911, and the part of the second sealing strip 2915 pasted on the first movable top cover 282 extends beyond the first movable top cover 282, when the retractable top cover movable part 2912 is flattened, the sealed connection between the retractable top cover fixing part 2911, the retractable top cover movable part 2912 and the first movable top cover 282 is realized.

The second platform section 23 and the third platform section 24 are respectively arranged at both ends of the first platform section 22 and are both rotatably connected to the first platform section 22, so that the second platform section 23 and the third platform section 24 can be disconnected or spliced relative to the first platform section 22 respectively, so that the tooling module 2 is in an open state or a closed state. When the tooling module 2 is in the closed state, the first platform section 22, the second platform section 23 and the third platform section 24 are spliced together to enclose a cavity structure. A first through hole 251 is provided on the first platform 25 of the cavity structure, and the first through hole 251 is hermetically connected to the rocket body 3 of the launch vehicle. A second through hole 261 is provided on the second platform 26 of the cavity structure, and the second through hole 261 is hermetically connected to the fairing 4 of the launch vehicle, thereby forming a sealed factory building structure. Since the environmental conditions of the sealed factory building structure are controllable, the vertical docking of the launch vehicle and the satellite, satellite testing and maintenance before launch and other work can be carried out in the sealed factory building structure; there is no need to additionally build a service tower with a closed factory building, thus saving costs.
