Abstract
Description
Technical Field
[0001] This utility model relates to the field of rocket reloading and positioning technology, and in particular to a rocket positioning and launch system. Background Technology
[0002] After the solid rocket completes testing in the technical area factory, the rocket body needs to be hoisted onto the main beam of the launch vehicle for fixation to ensure the stability of the rocket body during transportation. This process is called rocket loading onto the vehicle.
[0003] The process of loading the rocket onto the launch vehicle requires rapid positioning of the rocket body. When the solid rocket is hoisted onto the launch vehicle, a positioning device and a coordinated command method are used to guide the rocket body to be positioned with the locking device of the launch vehicle.
[0004] Currently, most rockets are positioned by installing a positioning rod at the tail and a corresponding positioning seat at the tail of the launch vehicle. The positioning seat is used to constrain the positioning rod to guide the rocket's positioning. However, since the existing positioning rod is inserted vertically, it is difficult to observe during the alignment process, resulting in poor positioning accuracy, low positioning precision, and cumbersome and time-consuming operation.
[0005] Therefore, there is an urgent need to provide a rocket positioning and launch system and positioning method to solve the problems existing in the current technology to a certain extent. Utility Model Content
[0006] The purpose of this invention is to provide a rocket positioning and launch system and positioning method, so as to optimize the rocket positioning and launch system to a certain extent and improve positioning accuracy and positioning efficiency.
[0007] This utility model provides a rocket positioning and launching system, including a launch vehicle, a rocket body, a first alignment device, and a second alignment device; the launch vehicle forms a carrying space for carrying the rocket body, the first alignment device is located at one end of the carrying space facing the front of the launch vehicle, and the first alignment device is capable of emitting a straight beam of light extending along the length direction of the carrying space; the second alignment device is disposed at the tail of the rocket body, and the second alignment device is capable of emitting a straight beam of light extending in the vertical direction.
[0008] The rocket positioning and launch system provided by this utility model also includes a docking device, which includes a positioning mechanism and an alignment mechanism. The alignment mechanism is disposed on the side wall of the tail of the rocket body. The positioning mechanism is connected to the launch vehicle and is disposed corresponding to the alignment mechanism. The positioning mechanism has a guide portion, and the alignment mechanism has a mating portion. The guide portion extends in a vertical direction, and the mating portion can be inserted into the guide portion and move within the guide portion.
[0009] Specifically, the positioning mechanism includes a positioning seat and a positioning plate; the positioning seat is connected to the launching vehicle, the positioning plate is vertically disposed on the positioning seat, the guide portion is formed on the positioning plate, and one end of the guide portion passes through the edge of the positioning plate to form an opening, so that the mating portion can enter the guide portion.
[0010] Specifically, there are two alignment mechanisms, and the two alignment mechanisms are arranged opposite each other on the side wall of the tail of the arrow body along the radial direction of the arrow body; the positioning mechanism is arranged in a one-to-one correspondence with the alignment mechanism.
[0011] Furthermore, the positioning seat includes a base, a slider, and a first locking member. The base is connected to the launch vehicle, and a slide is formed on the base along the width direction of the launch vehicle. The first locking member passes through the slider and enters the slide, allowing the slider to slide along the slide. The positioning plate is connected to the slider.
[0012] Furthermore, the positioning mechanism also includes a second locking member, which passes through the positioning seat and is connected to the launch vehicle.
[0013] The alignment mechanism includes a mounting base and an alignment post; the mounting base is connected to the arrow body, the alignment post is connected to the mounting base, and the axis of the alignment post extends radially along the arrow body.
[0014] Specifically, the alignment post includes a rolling part of the post body, the post body is connected to the mounting base, the rolling part is sleeved on the post body and can rotate relative to the post body.
[0015] Furthermore, the first alignment device includes a first connecting seat and a first transmitter, and the second alignment device includes a second connecting seat and a second transmitter; the first connecting seat is connected to the launch vehicle, the first transmitter is mounted on the first connecting seat, and the first transmitter is capable of emitting a beam of light extending along the length direction of the launch vehicle; the second connecting seat is connected to the arrow body, the second transmitter is mounted on the second connecting seat, and the second transmitter is capable of emitting a beam of light directed vertically toward the launch vehicle.
[0016] Compared with existing technologies, the rocket positioning and launch system provided by this utility model has the following advantages:
[0017] The rocket positioning and launching system provided by this utility model includes a launch vehicle, a rocket body, a first alignment device, and a second alignment device. The launch vehicle has a carrying space for carrying the rocket body. The first alignment device is located at one end of the carrying space facing the front of the launch vehicle, and the first alignment device can emit a straight beam of light extending along the length direction of the carrying space. The second alignment device is located at the tail of the rocket body, and the second alignment device can emit a straight beam of light extending in the vertical direction.
[0018] Analysis shows that the support space formed by the launch vehicle can stably support the rocket body and provide a stable installation space for the first alignment device. By placing the second alignment device at the tail of the rocket body, and considering that the first alignment device in this application can emit a straight beam of light along the length of the support space (i.e., the length of the launch vehicle), and the second alignment device can emit a straight beam of light extending vertically, it can be understood that since the first alignment device always forms a beam of light on the launch vehicle, the left and right positions of the rocket body can be determined using the beam of light formed by the first alignment device, and the front and rear positions and roll of the rocket body relative to the launch vehicle can be determined using the beam of light formed by the second alignment device. This allows the rocket body to quickly and accurately reach the landing position relative to the launch vehicle.
[0019] Meanwhile, as the rocket body moves toward the bearing space, the beams emitted by the first and second alignment devices can still be used as references to adjust the position of the rocket body in real time. This ensures that the rocket body lands accurately on the launch vehicle to a certain extent, eliminating the need for multiple lifting and lowering adjustments. This greatly improves the accuracy of hoisting and transportation, reduces the complexity of the operation, and increases operational efficiency.
[0020] Furthermore, this utility model also provides a positioning method using the above-mentioned rocket positioning and launch system, comprising the following steps: Step 1, installing the first alignment device, the second alignment device, and the docking device; Step 2, lifting the rocket body and transporting it towards the launch vehicle, activating the first alignment device and the second alignment device, and adjusting the crane using the beams emitted by the first alignment device and the second alignment device; Step 3, using the docking device to position and guide the rocket body until the rocket body is stably supported in the carrying space of the launch vehicle; Step 4, removing the first alignment device, the second alignment device, and the docking device.
[0021] The rocket positioning and launch system provided in this application enables accurate and rapid positioning of the rocket body relative to the launch vehicle, allowing the rocket body to accurately reach the launch vehicle without the need for multiple adjustments, thus greatly improving loading efficiency.

[0036] like Figure 1 Combination Figure 2 As shown, this utility model provides a rocket positioning and launching system, including a launch vehicle, a rocket body 1, a first alignment device 2, and a second alignment device 3; the launch vehicle has a carrying space for carrying the rocket body 1, the first alignment device 2 is located at one end of the carrying space facing the front of the launch vehicle, and the first alignment device 2 can emit a straight beam of light extending along the length direction of the carrying space; the second alignment device 3 is located at the tail of the rocket body 1, and the second alignment device 3 can emit a straight beam of light extending in the vertical direction.
[0037] Compared with existing technologies, the rocket positioning and launch system provided by this utility model has the following advantages:
[0038] The rocket positioning and launching system provided by this utility model can stably support the rocket body 1 through the carrying space formed by the launch vehicle, and can also provide a stable installation space for the first alignment device 2. By setting the second alignment device 3 at the tail of the rocket body 1, and the first alignment device 2 in this application can emit a straight beam of light along the length direction of the carrying space, that is, the length direction of the launch vehicle, and the second alignment device 3 can emit a straight beam of light extending in the vertical direction, it can be understood that since the first alignment device 2 always forms a beam of light on the launch vehicle, the left and right positions of the rocket body 1 can be determined by the beam of light formed by the first alignment device 2, and the front and rear positions and roll of the rocket body 1 relative to the launch vehicle can be determined by the beam of light formed by the second alignment device 3, so that the rocket body 1 can quickly and accurately reach the landing position relative to the launch vehicle.
[0039] Meanwhile, as the rocket body 1 moves toward the bearing space, the beams emitted by the first alignment device 2 and the second alignment device 3 can still be used as a reference to adjust the position of the rocket body 1 in real time. This ensures that the rocket body 1 lands on the launch vehicle accurately to a certain extent, without the need for multiple lifting and lowering adjustments. This greatly improves the accuracy of hoisting and transportation, reduces the complexity of the operation, and increases the efficiency of the operation.
[0040] It should be noted that the rocket body 1 in this application has a cylindrical structure. Therefore, the second alignment device 3 mentioned above is set at the top of the tail of the rocket body 1 when the rocket body 1 is placed horizontally, that is, at the highest point of the tail of the rocket body 1 away from the launch vehicle. This allows the rocket body 1 to be projected vertically toward the launch vehicle, thereby achieving accurate alignment of the rocket body 1 during the transport process.
[0041] Optionally, such as Figure 1 Combination Figure 2 As shown, the rocket positioning and launch system provided by this utility model also includes a docking device. The docking device includes a positioning mechanism 5 and an alignment mechanism 4. The alignment mechanism 4 is disposed on the side wall of the tail of the rocket body 1. The positioning mechanism 5 is connected to the launch vehicle and is disposed corresponding to the alignment mechanism 4. The positioning mechanism 5 forms a guide part 5051, and the alignment mechanism 4 forms a mating part. The guide part 5051 extends in the vertical direction, and the mating part can be inserted into the guide part 5051 and move within the guide part 5051.
[0042] This application, through a further configured docking device, can further improve the docking accuracy between the rocket body 1 and the launch vehicle. In practical applications, the beams emitted by the first alignment device 2 and the second alignment device 3 are used to initially locate the relative positions of the rocket body 1 and the launch vehicle, and then real-time alignment is performed as the rocket body 1 approaches the launch vehicle.
[0043] Understandably, before the rocket body 1 is fully supported on the launch vehicle, since the alignment mechanism 4 is located on the side wall of the tail of the rocket body 1 and the positioning mechanism 5 is located on the launch vehicle at the position corresponding to the alignment mechanism 4, as the rocket body 1 approaches, the mating part will move towards the guide part 5051 until it is inserted into the guide part 5051. Since the guide part 5051 extends vertically in this application, the cooperation between the guide part 5051 and the mating part can, on the one hand, enable the rocket body 1 to move stably towards the launch vehicle, and on the other hand, limit the descent of the rocket body 1, thereby ensuring that the position of the rocket body 1 is more accurate and does not require adjustment after it is fully placed on the launch vehicle.
[0044] Optionally, such as Figure 1 Combination Figure 2As shown, the positioning mechanism 5 in this application includes a positioning seat and a positioning plate 505; the positioning seat is connected to the launch vehicle, the positioning plate 505 is arranged vertically on the positioning seat, the guide part 5051 is formed on the positioning plate 505, and one end of the guide part 5051 passes through the edge of the positioning plate 505 to form an opening, so that the mating part can enter the guide part 5051.
[0045] In this application, the guide portion 5051 is a guide groove extending in a vertical direction, and the groove opening penetrates the edge of the positioning plate 505, thereby enabling the mating portion to enter the guide portion 5051 and complete the guidance of the mating portion.
[0046] Preferably, the number of alignment mechanisms 4 in this application is two, and the two alignment mechanisms 4 are arranged opposite each other on the side wall of the tail of the arrow body 1 along the radial direction of the arrow body 1; the positioning mechanism 5 is arranged in a one-to-one correspondence with the alignment mechanism 4.
[0047] It is understood that the cross-section of the arrow body 1 in this application is circular. Therefore, by arranging the two alignment mechanisms 4 radially opposite each other on the side wall of the tail of the arrow body 1, the arrow body 1 can be guided and limited on both sides during descent, thereby further ensuring the stability and positional accuracy of the arrow body 1.
[0048] Optionally, such as Figure 1 Combination Figure 2 As shown, the positioning seat in this application includes a seat body 501, a slider 502, and a first locking member 503. The seat body 501 is connected to the launch vehicle, and a slide rail 5011 is formed on the seat body 501 along the width direction of the launch vehicle. The first locking member 503 passes through the slider 502 and enters the slide rail 5011, so that the slider 502 can slide along the slide rail 5011. The positioning plate 505 is connected to the slider 502.
[0049] Since the diameters of different arrow bodies 1 are different, this application forms a slide 5011 on the base 501 and further installs a slider 502 so that the first locking member 503 passes through the slider 502 and enters the slide 5011, thereby enabling the slider 502 to slide along the slide 5011 and thus adjust the position of the slider 502.
[0050] Since the positioning plate 505 in this application is connected to the slider 502, when the slider 502 slides, it can drive the positioning plate 505 to move. Furthermore, since there are two positioning mechanisms 5 in this application, adjusting the position of the two sliders 502 can increase or decrease the distance between the two positioning plates 505, thereby adapting to arrow bodies 1 of different diameters, improving the overall system's adaptability, eliminating the need to develop devices of corresponding sizes for different arrow body diameters, and thus reducing construction costs to a certain extent.
[0051] It should be noted that the position of the base 501 corresponding to the slide 5011 in this application can be further marked with a scale, so that the distance between the two positioning plates 505 can be accurately adjusted through the scale, and the positions of the two positioning plates 505 relative to the base 501 can be kept consistent, thus avoiding the problem of the arrow body 1 being offset.
[0052] Optionally, such as Figure 1 Combination Figure 2 As shown, the positioning mechanism 5 in this application also includes a second locking member 504, which passes through the positioning seat and is connected to the launch vehicle.
[0053] The second locking member 504 in this application is a locking bolt. By screwing the second locking member 504, the end of the bolt can be made to abut against the body of the launch vehicle, thereby locking the position of the base 501.
[0054] It should be noted that screw holes can also be made at the corresponding positions on the launch vehicle. The cooperation between the second locking member 504 and the screw holes can further ensure the fixed position of the base 501, and avoid the problem of inaccurate positioning or the rocket body 1 failing to fall due to the displacement of the base 501 during the positioning process.
[0055] Optionally, such as Figure 1 As shown, the alignment mechanism 4 in this application includes a mounting base and an alignment post; the mounting base is connected to the arrow body 1, the alignment post is connected to the mounting base, and the axis of the alignment post extends radially along the arrow body 1.
[0056] The mounting base in this application is detachably connected to the rocket body 1, so that after positioning is completed, the mounting base can be removed to avoid the alignment mechanism 4 affecting the subsequent launch of the rocket body 1.
[0057] Preferably, the alignment post in this application includes a rolling part of the post body, the post body is connected to the mounting base, the rolling part is sleeved outside the post body, and can rotate relative to the post body.
[0058] The rolling part in this application can be a bearing sleeved on the column body. When the alignment column falls, the rolling of the bearing can make the falling process smoother and avoid jamming that causes wear on the alignment column and affects the positioning accuracy.
[0059] Optionally, such as Figure 1 As shown, the first alignment device 2 in this application includes a first connecting seat and a first transmitter, and the second alignment device 3 includes a second connecting seat and a second transmitter; the first connecting seat is connected to the launch vehicle, the first transmitter is mounted on the first connecting seat, and the first transmitter is capable of emitting a beam of light extending along the length direction of the launch vehicle; the second connecting seat is connected to the rocket body 1, the second transmitter is mounted on the second connecting seat, and the second transmitter is capable of emitting a beam of light directed vertically toward the launch vehicle.
[0060] The first connecting seat in this application is detachably connected to the launch vehicle, and the second connecting seat is detachably connected to the rocket body 1. This allows the first alignment device 2 and the second alignment device 3 to be used in different launch vehicles and different rocket bodies 1, thereby improving utilization. On the other hand, it can also avoid the first alignment device 2 from affecting the launch vehicle and the second alignment device 3 from affecting the rocket body 1 to a certain extent.
[0061] In addition, such as Figure 3 As shown, this utility model also provides a positioning method using the above-mentioned rocket positioning and launch system, including the following steps: Step 1: Install the first alignment device 2, the second alignment device 3, and the docking device; Step 2: Lift the rocket body 1 and transport it towards the launch vehicle, activate the first alignment device 2 and the second alignment device 3, and adjust the crane using the beams emitted by the first alignment device 2 and the second alignment device 3; Step 3: Use the docking device to position and guide the rocket body 1 until the rocket body 1 is stably supported in the carrying space of the launch vehicle; Step 4: Remove the first alignment device 2, the second alignment device 3, and the docking device.
[0062] The rocket positioning and launch system provided in this application enables accurate and rapid positioning of the rocket body 1 relative to the launch vehicle, allowing the rocket body 1 to accurately reach the launch vehicle without the need for multiple adjustments, thus greatly improving loading efficiency.
[0063] It should be added that in step two, when the rocket body 1 is transported in a direction close to the launch vehicle and reaches a position of about 1.5 meters, the first alignment device 2 and the second alignment device 3 are activated to achieve a reference for the position of the rocket body 1.
[0064] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
