Description

Technical Field

[0001] This invention relates to the field of rocket launch technology, specifically to an erection device for rocket launch. Background Technology

[0002] The rocket launcher is a device used to move the rocket from a horizontal position to a vertical position and to support the rocket during launch.

[0003] There are two main types of existing rocket erection methods. One method uses hydraulic cylinders and other components to push the rocket from a horizontal to a vertical position. During the entire erection process, the hydraulic cylinders must support a portion of the rocket's weight and provide power for its erection, resulting in a large load on the hydraulic cylinders. The other method uses lifting equipment to connect one end of a steel cable to the rocket's nose to erect the rocket. In this method, the lifting equipment also has to bear a portion of the rocket's weight and provide power for its erection, which also results in a large operating load.

[0004] Both of these methods can only erect one rocket at a time, and the installation and launch preparations for the next rocket can only begin after the first rocket has been launched. This results in low launch efficiency and long launch intervals, which cannot meet the requirements for rapid response in special circumstances. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an erection device for rocket launches, which has the advantages of high launch frequency, short launch interval, automatic rocket installation, and dynamic compensation for the launch base, thus solving the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an erection device for rocket launch, comprising an above-ground base installed on the ground and an underground base installed below the ground. The surface of the above-ground base is equipped with a drive mechanism, a switching erection mechanism and a pushing mechanism. The drive mechanism is connected to the switching erection mechanism.

[0009] Preferably, the switching erection mechanism includes a drive shaft 1 rotatably connected to a base on the ground via a bearing bracket 1. One end of the drive shaft 1 extends into a mounting plate and is fixedly connected to a spur gear 5. The spur gear 5 intermittently meshes with two spur gears 3.

[0010] Preferably, the clamping unit includes a fixed block fixed to the side of the switching disk, a hydraulic cylinder is mounted on the side of the fixed block, a movable block is fixed to the telescopic shaft of the hydraulic cylinder, the movable block is hinged to two grippers through two hinge rods, one end of each gripper is hinged to the fixed block, and an arc-shaped groove is provided at the other end of each gripper.

[0011] Preferably, the pushing mechanism includes a transmission shaft two rotatably connected to a base on the ground via a bearing bracket two. One end of the transmission shaft two is fixedly connected to a pulley two, which is connected to a pulley one via a belt. The other end of the transmission shaft two is fixedly connected to a bevel gear three, which meshes with a bevel gear four. The bevel gear four is fixedly connected to the bottom of a turntable via a connecting shaft two. A push block is fixedly connected to the turntable surface near the edge. The push block is slidably disposed in a push hole opened on a push rod. A movable column is movably connected to one end of the push rod. A pushing frame is fixedly connected to the top of the movable column. The pushing frame is provided with a placement groove. A "U"-shaped guide rod is fixedly connected to the side wall of the pushing frame. The guide rod is sleeved on the top of two movable frames. Both movable frames are movably connected to the top of a fixed frame. The fixed frame is fixedly connected to a base on the ground. Two electric push rods are installed on the inner side of the fixed frame. The telescopic shafts of the two electric push rods are respectively connected to the bottom of the two movable frames.

[0012] Preferably, the dynamic compensation mechanism includes a fixed plate installed inside the underground base. A second motor is installed at one end of the fixed plate. The output shaft of the second motor is rotatably connected to a bidirectional lead screw rotatably connected inside the fixed plate.

[0015] Preferably, the diameter ratio of the first, second, third, fourth and fifth spur gears is 4:2:2:1:4.

[0016] By employing the above technical solution, the present invention provides an erection device for rocket launch, which has at least the following beneficial effects:

[0017] 1. This rocket erection device, through the setting of a switching erection mechanism, fixes the rocket as a whole from the middle. In this way, the weight of the rocket is entirely on the clamping unit. When erecting the rocket, only the power required for erection needs to be provided, without sharing the weight of the rocket, thus reducing the operating load of motor one. Furthermore, by adopting the method of erecting around the middle of the rocket, the rocket can be flipped due to gravity during erection, and gravity shares part of the erection load, which can further reduce the operating load of motor one. When one side of the rocket is erected and is ready for launch, the other side can be installed, allowing the rockets on both sides to be installed and launched alternately, which greatly increases the launch frequency and shortens the launch interval, meeting the requirements of rapid response in special periods.

[0018] 2. The erecting device for rocket launch, by setting a pushing mechanism, can automatically push the rocket to the position of the clamping unit, and the clamping unit fixes the rocket, thus realizing the automatic installation of the rocket.

[0019] 3. The erection device used for rocket launch has a dynamic compensation mechanism. The position of the rocket placed on the push mechanism may be deviated, which will result in a deviation in the height of the bottom of the rocket after it is erected. At this time, the height of the launch base can be adjusted to compensate for the height deviation of the bottom of the rocket after it is erected, so that the rocket can be placed stably on the launch base and ensure its stable launch.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing an erection device for rocket launch.

[0037] Example 1:

[0038] Combination Figure 1-12 As shown, the present invention provides an erection device for rocket launch, including a ground base 1 installed on the ground and an underground base 2 installed underground. The surface of the ground base 1 is equipped with a drive mechanism 3, a switching erection mechanism 4, and a pushing mechanism 5. The drive mechanism 3 is connected to the switching erection mechanism 4 and provides power for the erection and installation of the rocket. The switching erection mechanism 4 is used to switch the positions of the clamping units 47 on both sides, so that the rockets on both sides can be launched alternately. There are two sets of pushing mechanisms 5, which are respectively located on both sides of the switching erection mechanism 4 and are also connected to the drive mechanism 3. The pushing mechanism 5 is used for automatically installing the rocket.

[0039] Two symmetrically arranged dynamic compensation mechanisms 6 are installed on the inner side of the underground base 2. The dynamic compensation mechanism 6 is used to compensate for the bottom deviation height of the rocket after it is installed and erected, so that the rocket can be placed stably on the launch base 67 and ensure its stable launch. The two dynamic compensation mechanisms 6 are respectively located below the two through slots provided on the ground base 1.

[0040] Specifically, the drive mechanism 3 includes a mounting plate 31 mounted on the surface of the base 1 on the ground. A motor 32 is mounted on the side wall of the mounting plate 31. A spur gear 33 is fixedly connected to the output shaft of the motor 32. Spur gears 34 are provided on both sides of the spur gear 33 and intermittently mesh with it. The spur gears 34 are rotatably connected to the inner side of the mounting plate 31 through a rotating shaft 35. A spur gear 36 is also fixedly mounted on the rotating shaft 35. The spur gear 36 intermittently meshes with a spur gear 37. The spur gear 37 is rotatably connected to the inner side of the mounting plate 31 through a rotating shaft 38. A pulley 39 is also fixedly connected to the rotating shaft 38.

[0041] As can be seen from the embodiment, starting the motor 32 can drive the first gear 33 to rotate half a turn. At this time, the first gear 33 meshes with the second gear 34 on the left and disengages from the second gear 34 on the right. This can drive the second gear 34 on the left to rotate one turn. The second gear 34 drives the third gear 36 to rotate one turn. The first half turn of the third gear 36 can mesh with the fourth gear 37 and disengage from the fifth gear 48. At this time, the fourth gear 37 rotates one turn, thereby moving the left pushing mechanism 5 and igniting the fire. The rocket is pushed onto the switching erection mechanism 4, which then installs and secures the rocket. The second half of the rotation of the third spur gear 36 disengages from the fourth spur gear 37 and engages with the fifth spur gear 48. At this time, the fifth spur gear 48 rotates 90° and drives the switching erection mechanism 4 to move. The switching erection mechanism 4 erects the rocket installed on the left side, while the clamping unit 47 on the right side returns to a horizontal state. When the first motor 32 works and drives the first spur gear 33 to rotate the second half of the rotation, the rocket on the right side can be installed and erected.

[0042] Example 2:

[0043] Combination Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 11 and Figure 12As shown, based on Embodiment 1, the switching erection mechanism 4 includes a transmission shaft 41 rotatably connected to the ground base 1 via a bearing bracket 49. One end of the transmission shaft 41 extends into the mounting plate 31 and is fixedly connected to a spur gear 48. The spur gear 48 intermittently meshes with two spur gears 36. The other end of the transmission shaft 41 is fixedly connected to a bevel gear 42. Both sides of the bevel gear 42 are provided with bevel gears 43 and mesh with them. The bevel gears 43 are fixedly connected to the switching disk 46 via a connecting shaft 44. The connecting shaft 44 is rotatably connected to the ground base 1 via a support seat 45. Multiple parallel clamping units 47 are fixedly connected to the side of the switching disk 46. The arrangement of multiple clamping units 47 can improve the firmness of the rocket fixation.

[0044] Specifically, the clamping unit 47 includes a fixing block 471 fixed to the side of the switching disk 46, a hydraulic cylinder 472 mounted on the side of the fixing block 471, a moving block 473 fixed to the telescopic shaft of the hydraulic cylinder 472, the moving block 473 being hinged to two grippers 475 via two hinge rods 474, one end of each gripper 475 being hinged to the fixing block 471, and an arc-shaped groove being provided at the other end of each gripper 475; the clamping unit 47 is used to fix the rocket.

[0045] Specifically, spur gear 1 (33) and spur gear 3 (36) are both incomplete gears, while spur gear 2 (34), spur gear 4 (37), and spur gear 5 (48) are all complete gears. Spur gear 1 (33) and spur gear 2 (34) have the same number of teeth, and spur gear 3 (36) and spur gear 4 (37) have the same number of teeth. The design of spur gear 1 (33) as an incomplete gear allows it to mesh with spur gear 2 (34) on both sides, and the design of spur gear 3 (36) as an incomplete gear allows it to mesh with spur gear 4 (37) and spur gear 5 (48) on both sides, thereby achieving the effect of separate driving.

[0046] Specifically, the diameter ratio of the first column gear 33, the second column gear 34, the third column gear 36, the fourth column gear 37, and the fifth column gear 48 is 4:2:2:1:4; ensuring that there is no motion interference between the switching erecting mechanism 4 and the pushing mechanism 5.

[0047] As can be seen from the embodiment, when the third spur gear 36 meshes with the fifth spur gear 48, the fifth spur gear 48 rotates and drives the first bevel gear 42 to rotate through the first transmission shaft 41. The first bevel gear 42 drives the switching disks 46 on both sides to rotate through the meshing action with the second bevel gear 43. The rotation of the switching disks 46 causes the clamping units 47 on both sides to switch positions. When one clamping unit 47 raises the rocket, the other clamping unit 47 just returns to a horizontal state, which facilitates the subsequent installation of the rocket. When installing the rocket, the hydraulic cylinder 472 works and drives the moving block 473 to move. The moving block 473 drives the two jaws 475 to move closer to each other and clamp the middle of the rocket through the hinge rod 474, thus fixing the rocket in place.

[0048] Example 3:

[0049] Combination Figure 1 , Figure 2 , Figure 8 and Figure 9 As shown, based on Embodiment 1, the pushing mechanism 5 includes a transmission shaft 2 52 rotatably connected to the base 1 on the ground via a bearing bracket 2 53. One end of the transmission shaft 2 52 is fixedly connected to a pulley 2 51, which is connected to a pulley 1 39 via a belt. The other end of the transmission shaft 2 52 is fixedly connected to a bevel gear 3 54, which meshes with a bevel gear 4 55. The bevel gear 4 55 is fixedly connected to the bottom of the turntable 57 via a connecting shaft 2 56. A push block 58 is fixedly connected to the surface of the turntable 57 near the edge, and the push block 58 is slidably disposed on the push rod 59. Inside the hole, a movable column 510 is movably connected to one end of the push rod 59. A push frame 511 is fixedly connected to the top of the movable column 510. The push frame 511 has a placement slot. A "U"-shaped guide rod 512 is fixedly connected to the side wall of the push frame 511. The guide rod 512 is sleeved on the top of two movable frames 513. Both movable frames 513 are movably connected to the top of a fixed frame 514. The fixed frame 514 is fixed to the base 1 on the ground. Two electric push rods 515 are installed on the inner side of the fixed frame 514. The telescopic shafts of the two electric push rods 515 are respectively connected to the bottom of the two movable frames 513.

[0050] As can be seen from the embodiment, when the spur gear 4 37 rotates, it can drive the pulley 1 39 to rotate. The pulley 1 39 drives the pulley 2 51 to rotate through the belt transmission. The pulley 2 51 drives the bevel gear 3 54 to rotate through the transmission shaft. The bevel gear 3 54 drives the turntable 57 to rotate through the meshing action with the bevel gear 4 55. The turntable 57 drives the push rod 59 to move through the push block 58. The push rod 59 drives the push frame 511 to move, thereby pushing the rocket on the push frame 511 to the position of the clamping unit 47. The clamping unit 47 fixes the rocket. Then the electric push rod 515 works and drives the movable frame 513 to move down. The movable frame 513 drives the push frame 511 to move down through the guide rod 512. After the push frame 511 is separated from the rocket, the turntable 57 continues to rotate and resets the push frame 511. The electric push rod 515 works to move the push frame 511 up, which also resets it.

[0051] Example 4:

[0052] Combination Figure 3 and Figure 10As shown, based on Embodiment 1, the dynamic compensation mechanism 6 includes a fixed plate 61 installed inside the underground base 2. A second motor 62 is installed at one end of the fixed plate 61. The output shaft of the second motor 62 is rotatably connected to a bidirectional lead screw 63 rotatably connected inside the fixed plate 61. Slider blocks 64 are screw-driven on the outer walls near both ends of the bidirectional lead screw 63. Both sliders 64 are slidably disposed inside the fixed plate 61. The side walls of both sliders 64 are hinged to the side of the lifting platform 66 through connecting rods 65. A launching base 67 is installed on the lifting platform 66.

[0053] Specifically, limit blocks 68 are fixedly connected to both sides of the lifting platform 66. The two limit blocks 68 are slidably arranged in the limit holes opened on both sides of the limit frame 69. The limit frame 69 is fixedly connected to the fixed plate 61. The setting of the limit blocks 68 and the limit frame 69 can make the lifting platform 66 more stable when moving up and down.

[0054] As can be seen from the embodiment, the start motor 62 drives the bidirectional lead screw 63 to rotate. The bidirectional lead screw 63 drives the two sliders 64 to move away from each other or closer together through the helical transmission. Thus, under the action of the connecting rod 65, the lifting platform 66 moves up and down. The height of the launch base 67 is adjusted to compensate for the bottom deviation height of the rocket after it is installed and erected.

[0055] As can be seen from the above embodiments, the usage process of this device is as follows: (Refer to...) Figure 1In the state shown, starting motor 32 drives spur gear 33 to rotate. Spur gear 33 meshes with spur gear 34 on the left and disengages from spur gear 34 on the right. At this time, it drives spur gear 34 on the left to rotate one revolution. Spur gear 34 drives spur gear 36 to rotate one revolution. The first half revolution of spur gear 36 meshes with spur gear 37 and disengages from spur gear 48. At this time, spur gear 37 rotates one revolution, thereby moving the left-side pushing mechanism 5 and pushing the rocket onto the switching erecting mechanism 4. Specifically, the rotation of spur gear 37 drives pulley 39 to rotate. Pulley 39 drives pulley 51 to rotate through the belt transmission. 51 drives bevel gear 3 54 to rotate via a drive shaft. Bevel gear 3 54, through meshing with bevel gear 4 55, drives turntable 57 to rotate. Turntable 57 drives push rod 59 to move via push block 58. Push rod 59 drives pusher frame 511 to move, thereby pushing the rocket on pusher frame 511 to the position of clamping unit 47. Clamping unit 47 fixes the rocket. The fixing process is as follows: hydraulic cylinder 472 works and drives moving block 473 to move. Moving block 473 drives two grippers 475 to move closer together and clamp the middle of the rocket through hinge rod 474, thus fixing the rocket. Then, electric push rod 515 on pusher mechanism 5 works to move pusher frame 511 down. After pusher frame 511 is detached from rocket, Turntable 57 continues to rotate and resets pusher 511. Electric push rod 515 moves pusher 511 upward, also resetting it. At this point, the rocket pushing operation is complete. Then, the second half of the rotation of spur gear 36 disengages from spur gear 47 and engages with spur gear 58. At this time, spur gear 58 rotates 90° and drives the switching erection mechanism 4. Specifically, when spur gear 36 engages with spur gear 58, spur gear 58 rotates and drives bevel gear 42 to rotate through transmission shaft 1 41. Bevel gear 1 42, through its engagement with bevel gear 2 43, drives the switching discs 46 on both sides to rotate. The rotation of the switching discs 46 causes the clamping units 47 on both sides to switch positions. When the rocket is erected, the clamping unit 47 on the other side is reset to a horizontal position. After the rocket on the corresponding side is erected, the dynamic compensation mechanism 6 below is controlled to work. Specifically, the motor 62 is started and drives the bidirectional lead screw 63 to rotate. The bidirectional lead screw 63 drives the two sliders 64 to move away from or towards each other through the helical transmission. Under the action of the connecting rod 65, the lifting platform 66 moves up and down. The height of the launch base 67 is adjusted to compensate for the bottom deviation height of the rocket after it is installed and erected. Then the erected rocket can be placed on the launch base 67. Then the clamping unit 47 is released to reflect the rocket. Then the above steps are repeated so that the installation and launch of the rockets on both sides can be carried out alternately.
