Description

Technical Field

[0001] The present invention relates to the field of rocket transfer positioning technology, and in particular to a rocket positioning launch system and a positioning method. Background Art

[0002] After the solid rocket completes testing in the technical area factory, the rocket body needs to be hoisted onto the launch vehicle's vertical main beam and fixed there to ensure the stability of the rocket body during transportation. This work is called rocket loading.

[0003] The rocket body needs to be quickly positioned when it is loaded onto the vehicle. When the solid rocket is hoisted onto the launch vehicle, a positioning device and coordinated command are used to guide the positioning of the rocket body and the launch vehicle's locking device.

[0004] At present, most of the time, a positioning rod is installed at the tail of the rocket, and a positioning seat is installed at the corresponding position of the tail of the launch vehicle. The positioning seat is used to constrain the positioning rod to guide the positioning of the rocket. However, since the existing positioning rod is vertically raised and lowered for insertion and positioning, it is inconvenient to observe during the alignment process, resulting in poor positioning accuracy, low positioning accuracy, cumbersome operation and long time consumption.

[0005] Therefore, there is an urgent need to provide a rocket positioning launch system and a positioning method to solve the problems existing in the prior art to a certain extent. Summary of the Invention

[0006] The purpose of the present invention is to provide a rocket positioning and launching system and a positioning method, so as to optimize the rocket positioning and launching system to a certain extent and improve the positioning accuracy and positioning efficiency.

[0007] The present invention provides a rocket positioning and launching system, comprising a launch vehicle, a rocket body, a first centering device and a second centering device; the launch vehicle is formed with a carrying space, the carrying space is used to carry the rocket body, the first centering device is located at one end of the carrying space facing the front of the launch vehicle, and the first centering device can emit a straight light beam extending along the length direction of the carrying space; the second centering device is arranged at the tail of the rocket body, and the second centering device can emit a straight light beam extending in the vertical direction.

[0008] Among them, the rocket positioning and launching system provided by the present invention also includes a docking device, which includes a positioning mechanism and an alignment mechanism. The alignment mechanism is arranged on the side wall of the tail of the rocket body, and the positioning mechanism is connected to the launch vehicle and is arranged corresponding to the alignment mechanism; the positioning mechanism is formed with a guide part, and the alignment mechanism is formed with a matching part. The guide part extends in a vertical direction, and the matching part can be inserted into the guide part and move in the guide part.

[0009] Specifically, the positioning mechanism includes a positioning seat and a positioning plate; the positioning seat is connected to the launching vehicle, and the positioning plate is arranged on the positioning seat in a vertical direction. The guide part is formed on the positioning plate, and one end of the guide part passes through the edge of the positioning plate to form an opening, so that the matching part can enter the guide part.

[0010] Specifically, there are two alignment mechanisms, and the two alignment mechanisms are arranged on the side walls of the tail of the arrow body in a radial direction of the arrow body and opposite to each other; the positioning mechanism is arranged in a one-to-one correspondence with the alignment mechanism.

[0011] Furthermore, the positioning seat includes a seat body, a slider and a first locking piece. The seat body is connected to the launch vehicle, and the seat body forms a slide along the width direction of the launch vehicle; the first locking piece passes through the slider and enters the slide, so that the slider can slide along the slide; the positioning plate is connected to the slider.

[0012] Furthermore, the positioning mechanism further includes a second locking member, which passes through the positioning seat and is connected to the launching vehicle.

[0013] Wherein, the alignment mechanism includes a mounting seat and an alignment column; the mounting seat is connected to the arrow body, the alignment column is connected to the mounting seat, and the axis of the alignment column extends along the radial direction of the arrow body.

[0014] Specifically, the alignment post includes a rolling portion of a post, the post is connected to the mounting seat, and the rolling portion is sleeved outside the post and can rotate relative to the post.

[0015] Furthermore, the first centering device includes a first connecting seat and a first launcher, and the second centering device includes a second connecting seat and a second launcher; the first connecting seat is connected to the launch vehicle, the first launcher is installed on the first connecting seat, and the first launcher can emit a light beam extending along the length direction of the launch vehicle; the second connecting seat is connected to the rocket body, the second launcher is installed on the second connecting seat, and the second launcher can emit a light beam in a vertical direction toward the launch vehicle.

[0016] Compared with the existing technology, the rocket positioning and launching system provided by the present invention has the following advantages:

[0017] The rocket positioning and launching system provided by the present invention includes a launching vehicle, a rocket body, a first centering device and a second centering device; the launching vehicle is formed with a carrying space, the carrying space is used to carry the rocket body, the first centering device is located at one end of the carrying space facing the front of the launching vehicle, and the first centering device can emit a straight light beam extending along the length direction of the carrying space; the second centering device is arranged at the tail of the rocket body, and the second centering device can emit a straight light beam extending in the vertical direction.

[0018] From this analysis, it can be seen that the carrying space formed by the launch vehicle can stably carry the arrow body, and can also provide a stable installation space for the first centering device. By arranging the second centering device at the tail of the arrow body, and the first centering device in this application can emit a straight light beam along the length direction of the carrying space, that is, the length direction of the launch vehicle, the second centering device can emit a straight light beam extending in the vertical direction. It can be understood that since the first centering device always forms a light beam on the launch vehicle, the light beam formed by the first centering device can be used to determine the left and right positions of the arrow body, and the light beam formed by the second centering device can be used to determine the front and rear positions and the roll amount of the arrow body relative to the launch vehicle, so that the arrow body can quickly and accurately reach the position to be dropped relative to the launch vehicle.

[0019] At the same time, as the rocket body moves toward the carrying space, the light beams emitted by the first centering device and the second centering device can still be used as a reference to adjust the position of the rocket body in real time, thereby ensuring to a certain extent that the rocket body lands accurately on the launch vehicle without the need for multiple lifting and lowering adjustments, greatly improving the accuracy of lifting and transportation, reducing the complexity of the operation, and improving work efficiency.

[0020] In addition, the present invention also provides a positioning method using the above-mentioned rocket positioning and launching system, comprising the following steps: step one, installing a first centering device, a second centering device and a docking device; step two, lifting the rocket body and transporting it in a direction close to the launch vehicle, opening the first centering device and the second centering device, and using the light beams emitted by the first centering device and the second centering device to adjust the crane; step three, using the docking device to position and guide the rocket body until the rocket body is stably carried in the carrying space of the launch vehicle; step four, removing the first centering device, the second centering device and the docking device.

[0021] The method for positioning a rocket using the rocket positioning and launching system provided in this application can accurately and quickly locate the position of the rocket body relative to the launch vehicle, so that the rocket body can accurately reach the launch vehicle without the need for multiple operations and adjustments, thereby greatly improving the loading efficiency.

[0036] like Figure 1 Combine Figure 2 As shown, the present invention provides a rocket positioning and launching system, comprising a launching vehicle, a rocket body 1, a first centering device 2 and a second centering device 3; the launching vehicle is formed with a carrying space, the carrying space is used to carry the rocket body 1, the first centering device 2 is located at one end of the carrying space facing the front of the launching vehicle, and the first centering device 2 can emit a straight light beam extending along the length direction of the carrying space; the second centering device 3 is arranged at the tail of the rocket body 1, and the second centering device 3 can emit a straight light beam extending in the vertical direction.

[0037] Compared with the existing technology, the rocket positioning and launching system provided by the present invention has the following advantages:

[0038] The rocket positioning and launching system provided by the present invention can stably support the rocket body 1 through the carrying space formed by the launching vehicle, and can also provide a stable installation space for the first centering device 2. By arranging the second centering device 3 at the tail of the rocket body 1, and the first centering device 2 in the present application can emit a straight light beam along the length direction of the carrying space, that is, the length direction of the launching vehicle, and the second centering device 3 can emit a straight light beam extending in the vertical direction. It can be understood that since the first centering device 2 always forms a light beam on the launching vehicle, the left and right positions of the rocket body 1 can be determined by using the light beam formed by the first centering device 2, and the front and rear positions and the roll amount of the rocket body 1 relative to the launching vehicle can be determined by using the light beam formed by the second centering device 3, so that the rocket body 1 can quickly and accurately reach the position to be dropped relative to the launching vehicle.

[0039] At the same time, as the rocket body 1 moves toward the carrying space, the light beams emitted by the first centering device 2 and the second centering device 3 can still be used as a reference to adjust the position of the rocket body 1 in real time, thereby ensuring to a certain extent that the position of the rocket body 1 on the launch vehicle is accurate, without the need for multiple lifting and lowering adjustments, greatly improving the accuracy of lifting and transportation, reducing the complexity of the operation, and improving the operation efficiency.

[0040] It should be noted here that the arrow body 1 in the present application has a cylindrical structure. Therefore, the second centering device 3 mentioned above in the present application is arranged when the arrow body 1 is in a horizontally placed state, at the top position of the tail of the arrow body 1, that is, the highest point position of the tail of the arrow body 1 away from the launch vehicle, so that a light beam can be projected toward the launch vehicle in a vertical direction, thereby achieving accurate alignment of the arrow body 1 during transportation.

[0041] Alternatively, as Figure 1 Combine Figure 2 As shown, the rocket positioning and launching system provided by the present invention also includes a docking device, which includes a positioning mechanism 5 and an alignment mechanism 4. The alignment mechanism 4 is arranged on the side wall of the tail of the rocket body 1, and the positioning mechanism 5 is connected to the launching vehicle and is arranged corresponding to the alignment mechanism 4; the positioning mechanism 5 is formed with a guide portion 5051, and the alignment mechanism 4 is formed with a matching portion, and the guide portion 5051 extends in a vertical direction, and the matching portion can be inserted into the guide portion 5051 and move in the guide portion 5051.

[0042] The present application further provides a docking device to further improve the docking accuracy between the rocket body 1 and the launch vehicle. In actual application, the relative positions of the rocket body 1 and the launch vehicle are preliminarily positioned using the light beams emitted by the first centering device 2 and the second centering device 3, and are aligned in real time as the rocket body 1 approaches the launch vehicle.

[0043] It can be understood that before the rocket body 1 is fully supported on the launch vehicle, since the alignment mechanism 4 is arranged on the side wall of the tail of the rocket body 1 and the positioning mechanism 5 is arranged at the position of the launch vehicle corresponding to the alignment mechanism 4, therefore, in the process of the rocket body 1 continuously approaching, the matching part will move in the direction of approaching the guide part 5051 until it is inserted into the guide part 5051. Since the guide part 5051 in this application extends in the vertical direction, the matching part can realize the stable movement of the rocket body 1 toward the launch vehicle through the cooperation between the guide part 5051 and the matching part. On the other hand, it can also play a limiting role in the descending process 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 completely placed on the launch vehicle.

[0044] Alternatively, as Figure 1 Combine Figure 2 As shown, the positioning mechanism 5 in the present application includes a positioning seat and a positioning plate 505; the positioning seat is connected to the launching vehicle, the positioning plate 505 is arranged on the positioning seat in the vertical direction, and the guide portion 5051 is formed on the positioning plate 505, and one end of the guide portion 5051 passes through the edge of the positioning plate 505 to form an opening, so that the matching portion can enter the guide portion 5051.

[0045] The guide portion 5051 in the present application is a guide groove extending in the vertical direction, and the groove passes through the edge of the positioning plate 505, so that the matching portion can enter the guide portion 5051 to complete the guidance of the matching portion.

[0046] Preferably, the number of the alignment mechanisms 4 in the present application is two, and the two alignment mechanisms 4 are arranged oppositely on the side walls 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 can be understood that the cross-section of the arrow body 1 in the present application is circular. Therefore, by arranging the two alignment mechanisms 4 on the side walls of the tail of the arrow body 1 in a radial direction relative to each other, the arrow body 1 can be guided and limited on both sides during the descent process, thereby further ensuring the stability and position accuracy of the arrow body 1.

[0048] Alternatively, as Figure 1 Combine Figure 2 As shown, the positioning seat in the present 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 the seat body 501 is formed with a slide 5011 along the width direction of the launch vehicle; the first locking member 503 passes through the slider 502 and enters the slide 5011, so that the slider 502 can slide along the slide 5011; the positioning plate 505 is connected to the slider 502.

[0049] Since the diameters of different arrow bodies 1 are different, the present application forms a slide 5011 on the base body 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 further adjusting the position of the slider 502.

[0050] Since the positioning plate 505 in the present application is connected to the slider 502, when the slider 502 slides, it can drive the positioning plate 505 to move. Moreover, since the number of positioning mechanisms 5 in the present application is also two, adjusting the positions 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 adaptability of the overall system, and eliminating the need to develop devices of corresponding sizes for different arrow body 1 diameters, thereby reducing construction costs to a certain extent.

[0051] It should be noted here that in the present application, the position of the seat body 501 corresponding to the slide 5011 can be further set 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 seat body 501 can be kept consistent, thereby avoiding the problem of offset of the arrow body 1.

[0052] Alternatively, as Figure 1 Combine Figure 2 As shown, the positioning mechanism 5 in the present application further includes a second locking member 504, and the second locking member 504 passes through the positioning seat and is connected to the launching vehicle.

[0053] The second locking member 504 in the present application is a locking bolt. By screwing the second locking member 504 , the end of the bolt can be brought into contact with the body of the launch vehicle, thereby locking the position of the base body 501 .

[0054] It should be noted here that a screw hole can also be opened at the corresponding position of the launch vehicle, so that the cooperation between the second locking member 504 and the screw hole can further ensure that the position of the base body 501 is fixed, avoiding the problem of inaccurate positioning or failure of the arrow body 1 to fall due to deviation of the base body 501 during the positioning process.

[0055] Alternatively, as Figure 1 As shown, the alignment mechanism 4 in the present application includes a mounting seat and an alignment post; the mounting seat is connected to the arrow body 1 , the alignment post is connected to the mounting seat, and the axis of the alignment post extends radially along the arrow body 1 .

[0056] The mounting seat in the present application is detachably connected to the arrow body 1 , so that after positioning is completed, the mounting seat can be removed to avoid the alignment mechanism 4 affecting the subsequent launch of the arrow body 1 .

[0057] Preferably, the alignment post in the present application includes a rolling portion of a post, the post is connected to the mounting seat, and the rolling portion is sleeved outside the post and can rotate relative to the post.

[0058] The rolling part in the present application can be a bearing sleeved on the column, so that when the alignment column falls, the rolling of the bearing can make the falling process smoother, avoiding the problem of wear on the alignment column caused by jamming and affecting the positioning accuracy.

[0059] Alternatively, as Figure 1 As shown, the first centering device 2 in the present application includes a first connecting seat and a first launcher, and the second centering device 3 includes a second connecting seat and a second launcher; the first connecting seat is connected to the launch vehicle, the first launcher is installed on the first connecting seat, and the first launcher can emit a light beam extending along the length direction of the launch vehicle; the second connecting seat is connected to the rocket body 1, the second launcher is installed on the second connecting seat, and the second launcher can emit a light beam in a vertical direction toward the launch vehicle.

[0060] The first connecting seat in the present application is detachably connected to the launch vehicle, and the second connecting seat is detachably connected to the rocket body 1. On the one hand, the first centering device 2 and the second centering device 3 can be used in different launch vehicles and different rocket bodies 1, thereby improving utilization. On the other hand, it can also avoid the first centering device 2 from affecting the launch vehicle and the second centering device 3 from affecting the rocket body 1 to a certain extent.

[0061] In addition, if Figure 3 As shown, the present invention also provides a positioning method using the above-mentioned rocket positioning and launching system, comprising the following steps: step one, installing the first centering device 2, the second centering device 3 and the docking device; step two, lifting the rocket body 1 and transporting it in the direction close to the launch vehicle, opening the first centering device 2 and the second centering device 3, and adjusting the crane using the light beams emitted by the first centering device 2 and the second centering device 3; step three, using the docking device to position and guide the rocket body 1 until the rocket body 1 is stably carried in the carrying space of the launch vehicle; step four, removing the first centering device 2, the second centering device 3 and the docking device.

[0062] The method for positioning a rocket using the rocket positioning and launching system provided in this application can accurately and quickly locate the position of the rocket body 1 relative to the launch vehicle, so that the rocket body 1 can accurately reach the launch vehicle without the need for multiple operations and adjustments, thereby greatly improving the loading efficiency.

[0063] It should be noted that in step 2, when the rocket body 1 is transported in the direction close to the launch vehicle and reaches a position of about 1.5 meters, the first centering device 2 and the second centering device 3 are opened to achieve a reference to the position of the rocket body 1.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
