The push-pull rod is located on the side of the first rack away from the second rack.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] When the rocket needs to be erected, the drive mechanism drives the support platform to slide out of the storage opening. The end of the support platform closest to the storage opening rests on the guide plate, and the support platform slides on the guide plate through the guide groove. The support platform slides out of the storage opening, forming a platform on the outside of the vehicle frame for rocket launch. When the support platform is not needed, the drive mechanism drives the support platform to slide back into the storage opening, and the support platform retracts into the vehicle frame. The support platform is carried with the launch vehicle. It can be slid out when needed and retracted when not needed, which is convenient and improves the ease of rocket launch.

[0019] When it is necessary to drive the support platform to move on the guide plate, push and pull the first rack, the first rack drives the first gear to rotate, the first gear drives the shaft to rotate, the shaft drives the second gear to rotate, the second gear drives the second rack, the second rack drives the support platform to slide on the guide plate, which can drive the support platform to slide out of the storage opening or into the storage opening;

[0020] After the rocket launch is completed, the rocket launch tube containing the rocket needs to be replaced. Unscrew the nut, remove the fixing rod, and open the clamping plate around the rotating shaft. The clamping plate rotates on the rotating shaft through the connecting block. The clamping plate drives the pressure block to rotate. The pressure block rotates 90° and moves out of the slot, releasing the pressure block from the insert plate. Then, lift the empty rocket launch tube and replace it with a rocket launch tube containing the rocket. Align the insert plate with the slot and insert the insert plate into the slot. Place the rocket launch tube on the receiving platform. Rotate the clamping plate. The clamping plate drives the pressure block to rotate through the connecting block. The pressure block presses the insert plate into the slot. Fit the clamping plate against the outer circumference of the rocket launch tube. Insert the insert block into the clamping plate. Insert the fixing rod into the clamping plate and the insert block. The fixing rod connects the two clamping plates, thus fixing the rocket launch tube on the receiving platform, achieving quick assembly and disassembly of the rocket launch tube.

[0021] During the pressing process of the clamping block pressing the insert plate, the pressure rod on the clamping block is inserted into the opening, and the pressure rod squeezes the slide plate. The slide plate compresses the spring downward. As the slide plate moves downward, it squeezes the limiting block through the slope of the slide groove. The limiting block drives the stop bar to slide in the slide groove. The limiting block extends out of the insert plate and inserts into the clamping plate until it slides to the side of the slide plate, and the insert plate is fixed in the slot. When it is necessary to release the clamping block from the insert plate, rotate the clamping block to release the pressure rod from the slide plate. The slide plate moves upward under the action of the spring, causing the limiting block to move into the groove. Under the attraction of the magnet, the magnet attracts the limiting block, causing it to move into the groove until it enters the groove. The limiting block disengages from the clamping plate, and the insert plate can be pulled out of the slot, improving the stability of the clamping plate in fixing the rocket launch tube.

A magnet 9 is embedded in the bottom of the groove 923. 231, the limiting block 924 is an iron block, and the magnet 9231 attracts the limiting block 924; the bottom surface of the slide plate 922 is provided with a placement groove 9221, and a spring 926 is provided in the placement groove 9221. One end of the spring 926 is pressed against the bottom of the placement groove 9221, and the other end of the spring 926 is pressed against the bottom inner wall of the slide groove 921; the top surface of the insert plate 92 is provided with an opening 927, the size of the opening 927 is smaller than the size of the top surface of the slide plate 922, and a pressure rod 9141 is connected to the side of the pressing block 914 near the insert plate 92. The pressure rod 9141 is pressed against the top surface of the slide plate 922.

[0049] During the pressing process of the clamping block 914 pressing against the insert plate 92, the pressure rod 9141 on the clamping block 914 is inserted into the opening 927. The pressure rod 9141 presses against the slide plate 922, and the slide plate 922 compresses the spring 926 downward. During the downward movement of the slide plate 922, the slide plate 922 presses against the limiting block 924 through the slope of the slide groove 921. The limiting block 924 drives the stop strip 9241 to slide in the sliding groove 925. The limiting block 924 extends out of the insert plate 92 and inserts into the clamping plate 81 until the limiting block 924 slides to the side of the slide plate 922, and the insert plate 92 is fixed in the slot 812; when needed To release the clamping block 914 from pressing the insert plate 92, rotate the clamping block 914 to release the clamping rod 9141 from pressing the slide plate 922. The slide plate 922 moves upward under the action of the spring 926, causing the limiting block 924 to move into the groove 923. Under the attraction of the magnet 9231, the magnet 9231 attracts the limiting block 924, causing the limiting block 924 to move into the groove 923 until the limiting block 924 enters the groove 923. The limiting block 924 disengages from the clamping plate 81, allowing the insert plate 92 to be pulled out of the slot 812, thus improving the stability of the clamping plate 81 in fixing the rocket launch tube 12.

The push-pull rod 612 is located on the side of the first rack 41 away from the second rack 42.

[0051] When the side frame 61 rotates around the hinge axis, the side frame 61 drives the push-pull rod 612, and the push-pull rod 612 drives the first rack 41 to slide on the support plate 113. The push-pull rod 612 drives the first rack 41. When the side frame 61 rotates to the set angle, the first rack 41 drives the second rack 42 to move through the first gear 44 and the second gear 45. The second rack 42 drives the support platform 2 to slide out of the storage port 111. The first erecting frame 6 drives the support platform 2 to slide out. The second erecting frame 8 makes the rocket launch tube 12 vertical on the top surface of the support platform 2.

[0052] The implementation principle of the launch platform with erection support and the rocket erection and launch device in this application embodiment is as follows: When the rocket needs to be erected, the drive mechanism 4 drives the support platform 2 to slide out of the storage port 111. The end of the support platform 2 near the storage port 111 is attached to the guide plate 3. The support platform 2 slides on the guide plate 3 through the guide groove 21. The support platform 2 slides out of the storage port 111 and forms a platform on the outside of the frame 11 for rocket launch. When the support platform 2 is not needed, the drive mechanism 4 drives the support platform 2 to slide into the storage port 111 and the support platform 2 is retracted into the frame 11. The support platform 2 is carried with the launch vehicle 1. When needed, the support platform 2 is slid out, and when not needed, the support platform 2 is retracted, which is more convenient and can improve the convenience of rocket launch.
