DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0022] The rocket needs to be transported from the production base to the launch site. During the transportation of the rocket, in order to facilitate the launch of the rocket, the rocket generally needs to be fixed on the erection frame. When arriving at the launch site, the rocket fixed on the erection frame is erected to the launch position together with the erection frame. In the process of fixing the rocket to the erection frame, in order to ensure the safety of the rocket, a support device needs to be set on the erection frame to bear the weight of the rocket. Generally, the length of the rocket is relatively long, ranging from more than ten meters to tens of meters or even hundreds of meters. Therefore, multiple support devices are generally set on the erection frame, and multiple support devices are arranged at intervals to bear the weight of the rocket. However, most of the current support devices are fixed, and due to the errors in processing and installation, during the process of fixing the shelf on the erection frame, multiple support devices may cause some support devices to be suspended. In this way, the rocket will not be balanced enough, and there is a risk of damaging the rocket; secondly, for some support devices, the force may be large, and there is a situation where it exceeds its load limit. In this way, some support devices may be damaged, resulting in risks in the transportation and launch of the rocket. To solve the above problems, the embodiment of the present application provides a rocket support device. The upper and lower directions are also defined in the embodiment of the present application. Specifically, the direction from the support base to the rocket body is defined as up in the embodiment of the present application, and the opposite direction is defined as down.

[0023] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4The rocket support device provided in the embodiment of the present application is installed on the erection frame and used to support the rocket, and includes an arrow support seat 100, a lifting device 200, a base 300 and a buffer device 400; the arrow support seat 100 includes an arrow support surface, and the arrow support surface is used to carry the rocket; the base 300 is fixedly installed on the erection frame, the fixed end of the lifting device 200 is fixedly arranged on the side of the base 300 away from the erection frame, the driving end of the lifting device 200 is drivingly connected to the buffer device 400, and the end of the buffer device 400 away from the base 300 is connected to the side of the arrow support seat 100 away from the rocket; the lifting device 200 can drive the arrow support seat 100 to rise and fall through the buffer device 400. It can be understood by those skilled in the art that the base 300 can be a steel structure to increase the strength of the base 300, and the base 300 can be fixed on the erection frame by bolts, etc. This is a prior art and will not be repeated in the embodiment of the present application.

[0024] It can also be understood that the arrow support seat 100 requires a higher strength, and therefore, the arrow support seat 100 can be a metal component, such as cast iron or the like. Of course, the arrow support seat 100 can also be formed by welding of steel plates, and the embodiment of the present application does not make specific restrictions. It can be understood by those skilled in the art that a mounting plate can also be provided at the bottom of the arrow support seat 100, and the arrow support seat 100 is fixed on the mounting plate, and then connected to the buffer device 400 through the mounting plate. Specifically, the arrow support seat 100 can be fixed on the mounting plate by fasteners such as bolts, which will not be repeated here. In this way, the connection part can be flexibly set on the mounting plate to facilitate the connection of the arrow support seat 100 with the buffer device 400 and the first guide device 500 and the second guide device 501. It can also be understood by those skilled in the art that the arrow support surface can be a curved surface, and the curvature of the arrow support surface is consistent with the curvature of the outer peripheral surface of the rocket. It should be noted that the curvature of the outer circumference of the rocket may be different due to different positions of the rocket. Therefore, the curvature of the arrow-supporting surface described in the embodiment of the present application is consistent with the curvature of the outer circumference of the rocket. The curvature change of the arrow-supporting surface caused by the different positions of the supporting device carrying the rocket should be considered. This is a well-known technology in the art and will not be repeated here. In the embodiment of the present application, by setting the arrow-supporting surface to fit the outer circumference of the rocket, the arrow-supporting seat 100 can increase the force-bearing area of ​​the arrow-supporting surface and the rocket when supporting the rocket, thereby reducing the pressure, avoiding damage to the outer circumference of the rocket during transportation, and ensuring the transportation and launch safety of the rocket.

[0025] It will be understood by those skilled in the art that the rocket is heavy and the road conditions during transportation are unpredictable. Therefore, in the embodiment of the present application, a buffer device 400 is also provided. In this way, the vibration of the rocket during transportation can be reduced, damage to the rocket during transportation can be avoided, and the safety of the rocket can be ensured.

[0026] Further, since rockets are generally long, multiple rocket support devices need to be used during transportation to support different parts of the rocket, thereby ensuring that the rocket can be balanced during transportation. However, due to processing and installation errors, when the rocket is placed on the support device, there may be a gap between the rocket and some support devices, resulting in some support devices not playing a supporting role, so that the rocket is not balanced enough, and there is a risk of damaging the rocket. In the embodiment of the present application, by setting a lifting device 200, the lifting and lowering of the arrow support seat 100 is driven by the lifting device 200. Therefore, when there is a gap between some arrow support seats 100 and the rocket due to installation errors, the height of the arrow support seat 100 can be adjusted by the lifting device 200, so that each arrow support seat 100 can contact the outer peripheral surface of the rocket, so that the force of each support device is balanced, thereby ensuring that the rocket is balanced during transportation and ensuring the safety of the rocket during transportation.

[0027] In some embodiments, the rocket support device further includes a first guide device 500 and a second guide device 501; the end of the buffer device 400 away from the base 300 is hinged to the side of the arrow support seat 100 away from the rocket. Specifically, the hinge can be achieved by a pin shaft, etc., which is a well-known technology in the field and will not be described here.

[0028] One end of the first guide device 500 is connected to the side of the arrow support seat 100 away from the rocket, and the other end of the first guide device 500 is fixed to the erection frame; one end of the second guide device 501 is connected to the side of the arrow support seat 100 away from the rocket, and the other end of the second guide device 501 is fixed to the erection frame; the first guide device 500 and the second guide device 501 are respectively located on both sides of the buffer device 400. It can be understood that the first guide device 500 and the second guide device 501 are both hingedly connected to the arrow support seat 100. The specific hinge method can also be achieved by a pin shaft, which will not be repeated here.

[0029] Those skilled in the art will appreciate that the hinge point between the buffer device 400 and the arrow support seat 100 is generally in the middle of the bottom of the arrow support seat 100. Thus, in order to ensure the stability of the arrow support seat 100 during the lifting and lowering process of the arrow support seat 100, the embodiment of the present application is provided with a first guide device 500 and a second guide device 501 on both sides of the arrow support seat 100, respectively, so as to ensure that the arrow support seat 100 can be lifted and lowered smoothly. In addition, by limiting the first guide column 520 and the second guide column, the rocket can be prevented from tilting during the lifting and transportation process. In addition, in the embodiment of the present application, the arrow support seat 100 and the buffer device 400 are hinged, and the force on the arrow support seat 100 can also be balanced. For example, when the force applied by the rocket on the arrow support seat 100 is biased towards the first guide device 500, the arrow support seat 100 can be slightly rotated toward the first guide device 500. Since the first guide device 500 and the arrow support seat 100 are hinged, the first guide device 500 can be slightly moved downward without interference, thereby balancing the force on the hinge point between the arrow support seat 100 and the buffer device 400, avoiding damage to the arrow support seat 100 and the buffer device 400, and ensuring that the supporting force applied by the arrow support seat 100 to the rocket is more balanced, so that the force on the rocket is balanced, avoiding large local forces on the rocket and damaging the rocket, thereby ensuring the transportation safety of the rocket. Those skilled in the art can also understand that the rotation angle of the arrow support 100 should be very small, which is related to the fitting clearance between the first guide sleeve 510 and the first guide column 520 in the first guide device 500. The smaller the fitting clearance, the smaller the rotation amplitude and the higher the guiding accuracy. Those skilled in the art can make settings and choices as needed, and no specific restrictions are made here.

[0030] In some embodiments, the first guide device 500 includes a first guide sleeve 510 and a first guide column 520, one end of the first guide sleeve 510 is fixed to the erecting frame, the first guide column 520 is slidably disposed in the guide hole of the first guide sleeve 510, and the end of the first guide column 520 away from the first guide sleeve 510 is fixedly connected to the arrow support seat 100; the second guide device 501 includes a second guide sleeve and a second guide column, both ends of the second guide sleeve are fixed to the erecting frame, the second guide column is slidably disposed in the guide hole of the second guide sleeve, and both ends of the second guide column away from the second guide sleeve are fixedly connected to the arrow support seat 100. It can be understood that the structures of the first guide device 500 and the second guide device 501 can be the same. It can be understood by those skilled in the art that the bottom of the first guide sleeve 510 can be provided with a mounting hole, and then fixed to the erecting frame by bolts, for example, a connecting plate can be provided at the bottom of the first guide, and a through hole can be opened on the connecting plate; the installation of the second guide sleeve can refer to the first guide sleeve 510, which will not be repeated here. The first guide post 520 is slidably disposed in the guide hole of the first guide sleeve 510 to achieve guidance, which is a prior art and will not be described in detail here. The structure of the guide sleeve and the guide post is simple to install and accurate in guiding.

[0031] In some embodiments, the first guide device 500 also includes a first limiting member 530, which is fixedly connected to one end of the first guide sleeve 510 facing the arrow supporting seat 100, and the distance between the first limiting member 530 and the arrow supporting seat 100 is smaller than the distance between the first guide sleeve 510 and the arrow supporting seat 100; the second guide device 501 also includes a second limiting member, which is fixedly connected to the two ends of the second guide sleeve facing the arrow supporting seat 100, and the distance between the second limiting member and the arrow supporting seat 100 is smaller than the distance between the second guide sleeve and the arrow supporting seat 100.

[0032] In the embodiment of the present application, since the weight of the rocket is relatively large, in order to avoid failure of the first guide assembly and / or the second guide assembly, resulting in collisions between the rocket and the erection frame or other components, a first limiter 530 and a second limiter are also provided in the embodiment of the present application. Specifically, the first limiter 530 can be fixed to the upper end of the first guide sleeve 510. For example, a connecting plate can also be provided at the upper end of the first guide sleeve 510, and the first limiter 530 is then fixed to the connecting plate. It can be understood by those skilled in the art that the first limiter 530 can include a limiter column and a fixing nut, one end of the limiter column is provided with an external thread, a through hole is provided on the connecting plate at the upper end of the first guide sleeve 510, one end of the limiter column provided with an external thread is inserted into the through hole, the other end of the limiter column extends toward the arrow support seat 100, and the limiter column is fixed to the connecting plate by a fixing nut. It should be noted that, in the embodiment of the present application, the spacing between the limit column and the arrow support seat 100 is smaller than the spacing between the upper end of the first guide sleeve 510 and the arrow support seat 100; in this way, when the first guide device 500 fails, or the lifting device 200 drives the arrow support seat 100 to move downward beyond the limit, the limit column can support the arrow support seat 100 to prevent the arrow support seat 100 from further descending, thereby ensuring that the rocket's downward travel is within the set range, avoiding collisions between the rocket and the erection frame or other components, and ensuring the safety of the rocket. It can be understood by those skilled in the art that the structure and function of the second limit member can refer to the structure and function of the first limit member 530, and will not be repeated here.

[0033] In some embodiments, the first guide device 500 further includes a first scale 540 and a first pointer 550. The first guide sleeve 510 is provided with a first sliding hole in the axial direction. The first scale 540 is fixed to the outer circumference of the first guide sleeve 510 in the axial direction, and the first scale 540 is located on the side close to the first sliding hole. One end of the first pointer 550 is fixedly connected to the first guide post 520, and the other end of the first pointer 550 passes through the first sliding hole and points to the first scale 540. It can be understood that the first scale 540 can be flexible, such as paper, and is pasted on the outer circumference of the first guide sleeve 510; of course, the first scale 540 can also be metal, riveted or welded to the outer circumference of the first guide sleeve 510. Those skilled in the art can set it as needed, and no specific restrictions are made here. It can also be understood that a threaded hole can be started on the first guide post 520, and the first pointer 550 can be screwed on the first guide post 520. This is a well-known technology in the art and will not be described in detail here.

[0034] The second guide device 501 also includes a second scale and a second pointer. The second guide sleeve is provided with a second sliding hole in the axial direction. The second scale is fixed to the outer peripheral surface of the second guide sleeve in the axial direction, and the second scale is located on two sides close to the second sliding hole. The two ends of the second pointer are fixedly connected to the second guide column, and the other two ends of the second pointer pass through the second sliding hole and point to the second scale. The installation of the second scale and the second pointer can refer to the first scale 540 and the first pointer 550, and will not be repeated here.

[0035] It can be understood by those skilled in the art that, although the arrow support seat 100 may rotate around the buffer device 400, since the matching clearance between the guide column and the guide sleeve in the first guide device 500 and the second guide device 501 is generally very small, it can be considered that the influence of the rotation of the arrow support seat 100 on the first pointer 550 or the second pointer is negligible. Therefore, in general, in a rocket support device, the positions pointed to by the first pointer 550 and the second pointer should be consistent. In the embodiment of the present application, by setting the first pointer 550 and the second pointer, the stroke of the lifting device 200 can be known. In general, when the rocket is placed on the support device, the first pointer 550 and the second pointer should point to the middle part of the scale, for example, the part can be marked as zero. When the rocket rises, the pointer moves up and points to a positive value; when the rocket moves down, the pointer moves down and points to a negative value. In this way, the deviation of the support device from the theoretical position can be known on the one hand, and the stroke of the lifting device 200 and the state at this time can also be known through the pointing of the pointer, so that it is easy to operate.

[0036] In some embodiments, the buffer device 400 includes a spring 410 and a connecting member 420, and the rocket support device also includes a limit assembly 600, the limit assembly 600 includes a limit seat 610, the limit seat 610 is fixedly connected to the erection frame, the limit seat 610 is provided with a accommodating cavity 611 that penetrates the limit seat 610 axially, the spring 410 is located in the accommodating cavity 611, the driving end of the lifting device 200 extends from the lower opening of the limit seat 610 into the accommodating cavity 611 and is connected to the spring 410, one end of the connecting member 420 is connected to one end of the spring 410 away from the lifting device 200, and the other end of the connecting member 420 is connected to the arrow support seat 100. It can be understood that the limit seat 610 also includes an upper cover plate and a lower cover plate, the upper cover plate covers the upper opening of the accommodating chamber 611, and the lower cover plate covers the lower opening of the accommodating chamber 611. Through holes are provided on the upper cover plate and the lower cover plate. The connecting member 420 may include a connecting rod and a connecting plate 421. The connecting plate 421 is located in the accommodating chamber 611. One end of the connecting rod 422 is fixedly connected to the connecting plate 421, and the other end passes through the through hole of the upper cover plate and is connected to the arrow support seat 100. The driving end of the lifting device 200 passes through the opening of the lower cover plate and is connected to the spring 410 in the accommodating chamber 611. Specifically, a baffle may be provided between the lifting device 200 and the spring 410, that is, the spring 410 may be located between the baffle and the connecting plate 421.

[0037] In the embodiment of the present application, by setting the spring 410, the vibration of the rocket during transportation can be reduced by the buffering effect of the spring 410. Further, in the embodiment of the present application, when the rocket is placed on the arrow support seat 100, the spring 410 is in a compressed state. Since the weight of the rocket is generally large, the spring 410 generally selects a spring 410 with a larger elastic modulus. For example, according to the working load range of 16 tons to 18 tons, after design and calculation, the free length of the spring 410 is selected to be 975mm. When the rocket is placed on the arrow support seat 100, the spring 410 is compressed. At this time, the height of the spring 410 is 567mm, which is the initial installation height of the spring 410, and the compression height is 408mm. The stiffness of the spring 410 is selected to be 392N / mm. At this time, in the initial installation state, the corresponding load of the spring 410 is about 15.99 tons. During transportation, due to changes in working conditions, the rocket will experience an acceleration change of 1g to 2g. According to the input load upper limit of 18 tons, the corresponding height of spring 410 is 516mm, and the stroke change of spring 410 is 51mm. Those skilled in the art can design spring 410 with reference to the above parameters. Of course, those skilled in the art can also design it according to actual conditions.

[0038] In some embodiments, the limiting assembly 600 further includes a limiting rod 620, the limiting rod 620 is fixedly connected to the limiting seat 610, and the upper end of the limiting rod 620 is flush with the upper end of the first limiting member 530. The limiting rod 620 can be fixed to the upper cover plate and the lower cover plate, for example, by screwing. It can be understood by those skilled in the art that the number of the limiting rods 620 can be two, three, or four, etc., and those skilled in the art can set it according to actual conditions, and no specific limitation is made here. In the embodiment of the present application, when the lifting device 200 fails, the arrow support seat 100 will fall downward due to the loss of support from the lifting device 200. In order to prevent the arrow support seat 100 from colliding with the buffer device 400 and the rocket from colliding with the erection frame, a limit rod 620 is further provided in the embodiment of the present application. The limit rod 620 is fixed to the limit seat 610, and the limit seat 610 is fixed to the erection frame. Therefore, the limit rod 620 can support the arrow support seat 100 to prevent the arrow support seat 100 from directly colliding with the limit seat 610. The limit rod 620 is flush with the height of the end of the limit column facing the arrow support seat 100. Therefore, when the lifting device 200 fails, the limit column and the limit rod 620 can simultaneously support the arrow support seat 100, further ensuring the safety of the rocket.

[0039] In some embodiments, the buffer device 400 also includes a pressure sensor 430, and the pressure sensor is arranged between the arrow support seat 100 and the connecting member 420. Specifically, the pressure sensor 430 can be purchased directly, and can be fixed to the arrow support seat 100 and the connecting member 420 by bolts, etc., which are all prior arts, and the embodiments of the present application will not be repeated. It can be understood by those skilled in the art that during the transportation of the rocket, a plurality of supporting devices are generally required. Therefore, through the pressure sensor 430, the pressure given by the rocket to each supporting device can be known. In this way, it is easy to adjust each supporting device, so that the pressure of the rocket on each supporting device is consistent, ensuring that the rocket is balanced and the safety of the rocket is ensured.

[0040] In some embodiments, the lifting device 200 includes a lifting assembly, a driving device and a hand wheel, one end of the lifting assembly fixes the base 300, and the other end of the lifting device 200 is driven to connect the buffer device 400, and the driving device and the hand wheel are both driven to connect the lifting assembly. It can be understood by those skilled in the art that the driving device can be a motor, a hydraulic device, etc., and preferably a motor in the embodiment of the present application. The lifting device 200 can be a structure such as a threaded screw, which is a prior art and will not be repeated in the embodiment of the present application.
