Technical Field

[0001] This utility model relates to the field of rocket transportation technology, specifically a positioning device for rocket transportation. Background Technology

[0002] Launch vehicles are the primary means of launching satellites and other spacecraft. With the rapid development of space launch needs, launch payloads are becoming increasingly diverse, and the number of launches is increasing significantly, which places higher demands on the quantity and quality of launch vehicles.

[0003] In response to this, utility model patent CN214728459U discloses a positioning structure for rocket transportation, comprising a positioning pin assembly and a positioning hole assembly. The positioning pin assembly is used to be mounted on a transport vehicle, and the positioning hole assembly is used to be mounted on a frame for fixing the rocket. The positioning hole assembly includes a first positioning block and a second positioning block. The first positioning block is located inside the second positioning block, and one end of the first positioning block is disposed on a first guide member disposed inside the second positioning block.

A gear 204 meshes between the second racks 205 and the first racks 203. Two support blocks 212 are fixedly provided on one side of the second racks 205. An adjusting screw 213 is rotatably connected between the two support blocks 212. A locking stop bar 214 is threadedly connected to the outer wall of the adjusting screw 213.

[0030] A stepper motor 102 is installed at one end of the drive box 101. The output end of the stepper motor 102 is fixedly connected to one end of the bidirectional lead screw 103. Two moving blocks 104 are respectively inserted and connected to the two sides of the inner wall of the drive box 101. A retaining ring 110 is threadedly connected to the top of the outer wall of the movable column 109. A connecting spring 112 is fixed between the connecting piece 105 and the movable block 111. The connecting spring 112 is sleeved with the outer wall of the movable column 109. Movable wheels 107 are fixedly installed at the four corners of the bottom of each positioning platform 106, and a rubber plate 108 is fixedly installed at the top of each positioning platform 106.

[0031] Each first rack 203 has a pull ring fixed at one end, and an L-shaped support rod 207 fixed at the other end. A force-bearing diagonal rod 208 is fixed at the top of each L-shaped support rod 207. A second straight groove 209 is formed in the middle of the inner wall of the slot 202. Second straight slide bars are slidably connected to both sides of the inner wall of the second straight groove 209. A second rack 205 is fixed at the top of each second straight slide bar. The bottom ends of the two gears 204 are rotatably connected to the surface of the slot 202. The base plate 2... One side of each end of the 01 is provided with a first opening corresponding to the first rack 203, and the middle of each end of the base plate 201 is provided with a second opening corresponding to the second rack 205.

[0032] Working principle: When using this positioning device, it is placed on a transport vehicle and fixed to the vehicle surface by the first fixed horizontal plate 3 and the second fixed horizontal plate 4. When positioning and fixing the rocket, the stepper motor 102 rotates forward, driving the bidirectional lead screw 103, which in turn brings the two moving blocks 104 closer together, thus bringing the two positioning platforms 106 closer together. When the rocket is placed on the positioning device, the rubber plate 108 on the positioning platform 106 is subjected to force, which causes the movable column 109 to move within the movable hole opened in the connector 105, and the movable block 111 moves downward. The movement causes the connecting spring 112 to extend, ensuring that the movable wheel 107 connected to the positioning platform 106 falls into the slot 202 opened in the base plate 201. The two positioning platforms 106 position the rocket. At this time, the force-bearing diagonal bar 208 on the L-shaped support rod 207 is stressed, which causes the first rack 203 to move and act on the gear 204. The gear 204 can then drive the two second racks 205 to move closer, thereby limiting the movable wheel 107 on the outer side of the two locking bars 214 positioning platforms 106 and ensuring the stability of rocket transportation.
