Description

Technical Field

[0001] The present invention relates to the technical field of rocket simulation erection, and particularly to a rocket simulation erection device. Background Art

[0002] In the field of aerospace, the test launch modes of rockets mainly include the one-horizontal-two-vertical mode, the three-vertical mode, and the three-horizontal mode. The one-horizontal-two-vertical mode means horizontal transportation, vertical assembly, and vertical testing. The three-vertical mode means vertical transportation, vertical assembly, and vertical testing. The three-horizontal mode means horizontal assembly, horizontal testing, and horizontal transportation. Compared with the one-horizontal-two-vertical mode and the three-vertical mode, under the three-horizontal mode, all the assembly and testing work of the rocket body is completed in the technical workshop. Since it is not affected by the weather, the assembly and testing time is relatively determined, and there is no need for high-level tooling to support the assembly and testing, reducing the height requirement for the technical workshop. It has the advantages of low center of mass, high efficiency, and good mobility. After the entire rocket is horizontally transported to the launch position, it can be quickly erected, shortening the time for a single rocket body to occupy the firing range and being beneficial to improving the utilization rate of the firing range. Therefore, the three-horizontal mode is a commonly used test launch mode. Among them, a transportation device is needed to transport the rocket to the erection position, and then an erection device is used to erect the horizontal rocket to a vertical state.

[0003] In order to discover and solve the problems existing in the above three test launch modes of rockets in advance, rocket simulation erection and launch are often carried out, that is, a simulation erection device is used to erect and launch a rocket model. The rocket model is made of the same material as the actual rocket, but its volume is smaller than that of the actual rocket. Since both the rocket model and the actual rocket are made of composite materials, compared with conventional materials, although the application of composite materials to the rocket shell has more advantages in weight reduction, however, composite materials are prone to deformation, the erection process has poor stability, and safety problems are likely to occur. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a rocket simulation erection device that can conveniently clamp and fix the entire rocket model and will not cause deformation to the outer wall of the rocket model during the erection process, so that the rocket model is more stable and safe during erection.

An erection arm is hinged to the upper side surface of the frame main body. A hydraulic rod is hinged between the erection arm and the frame main body. The two ends of the erection arm are respectively a hinged end and a free end. The hinged end of the erection arm is hinged to the upper side surface of the frame main body. A frame is fixedly provided at the free end of the erection arm. An arc-shaped groove is provided on the frame. A first clamping assembly is provided on the frame.

One end of each of the two arc-shaped clamping rods is respectively hinged to the piston rod of the corresponding first hydraulic cylinder. The other ends of the two arc-shaped clamping rods can move closer to or away from each other under the action of the two first hydraulic cylinders. When the other ends of the two arc-shaped clamping rods move closer to each other, the other ends of the two arc-shaped clamping rods and the arc-shaped groove of the outer frame can jointly form a circular clamping opening, and the axis of the circular clamping opening is arranged in the same direction as the length direction of the erection arm.

[0007] The rocket simulation erection device of the present invention, wherein clamping rod grooves are provided on the opposite two side surfaces of the other ends of the two arc-shaped clamping rods, and the connection line between the centers of the two clamping rod grooves passes through the center of the circular clamping opening.

[0008] The rocket simulation erection device of the present invention, wherein the second clamping assembly includes two sets of clamping members. The two sets of clamping members are respectively located on the opposite sides of the center connection line of the hinged end and the free end of the erection arm. The clamping member includes a second hydraulic cylinder and a third hydraulic cylinder. The second hydraulic cylinder and the third hydraulic cylinder are respectively fixedly arranged on two support platforms. The two support platforms are respectively fixedly arranged on the erection arm through support columns. A baffle is fixedly connected between the two support platforms. A first clamping plate is vertically fixedly arranged on the piston rod of the second hydraulic cylinder. A second clamping plate is vertically fixedly arranged on the piston rod of the third hydraulic cylinder. The first clamping plate and the second clamping plate are both abutted against the baffle. The first clamping plate and the second clamping plate are arranged oppositely. The second hydraulic cylinder is arranged along the length direction of the erection arm and the piston rod of the second hydraulic cylinder faces the free end of the erection arm. The third hydraulic cylinder is inclined to the length direction of the erection arm and the piston rod of the third hydraulic cylinder faces the hinged end of the erection arm. The distance between the two third hydraulic cylinders gradually increases along the direction from the hinged end to the free end of the erection arm. The first clamping plate and the second clamping plate can move closer to or away from each other respectively under the action of the second hydraulic cylinder and the third hydraulic cylinder.

[0009] The rocket simulation erection device of the present invention, wherein fourth hydraulic cylinders are fixedly arranged on the outer sides around the vehicle frame main body. The cylinder bodies of the fourth hydraulic cylinders are fixedly arranged on the vehicle frame main body. The piston rods of the fourth hydraulic cylinders are arranged downward. A support base is fixedly arranged on the piston rods of the fourth hydraulic cylinders.

[0010] The rocket simulation erection device of the present invention, wherein one end of a steel wire rope is connected to the outer sides around the vehicle frame main body, and the other end of the steel wire rope is connected to a turnbuckle.

[0011] The rocket simulation erection device of the present invention, wherein the erection arm is of a frame structure, a connecting frame is fixedly provided on one side of the erection arm away from the vehicle frame body, one end of the hydraulic rod is hinged on the vehicle frame body, and the other end of the hydraulic rod passes through the erection arm and is hinged on the connecting frame.

[0012] The rocket simulation erection device of the present invention, wherein the connecting frame is rectangular, the length direction of the connecting frame is arranged in the same direction as the width direction of the erection arm, and side plates are fixedly connected between the two ends of the connecting frame in the length direction and the erection arm respectively.

[0013] The rocket simulation erection device of the present invention, wherein the vehicle frame body is of a rectangular frame structure, vehicle frame bases are fixedly provided at the four corners of the lower side of the vehicle frame body respectively, fourth hydraulic cylinders are fixedly provided at the four corners on the outer sides of the four weeks of the vehicle frame body respectively, and one ends of steel ropes are connected at the four corners on the outer sides of the four weeks of the vehicle frame body respectively.

[0014] The rocket simulation erection device of the present invention, wherein a control box is fixedly provided on the vehicle frame body.

[0015] The difference between the rocket simulation erection device of the present invention and the prior art lies in that when the rocket simulation erection device of the present invention is in use, the hydraulic rod is in a contracted state, that is, the erection arm is arranged horizontally, the rocket model is placed on the erection arm, and the upper part of the rocket model is located in the arc-shaped groove of the outer frame. Then, the upper part of the rocket body is clamped by the cooperation of the first clamping assembly and the outer frame. A connecting piece is fixedly provided on the outer side wall of the middle and lower sections of the rocket body, and the connecting piece is clamped by the second clamping assembly, that is, the middle and lower sections of the rocket body are clamped and fixed. Since the second clamping assembly does not directly contact the outer side wall of the rocket body, the deformation of the rocket body during the erection process can be reduced. Then, the hydraulic rod is changed from the contracted state to the extended state, so the hydraulic rod erects the entire erection arm, and the rocket model also follows the erection arm to complete the erection, and then the launch can be carried out.

Detailed implementation mode

[0023] As Figure 1 shown, and in combination with Figures 2 - 5 shown, the rocket simulation erection device of the present invention includes a vehicle frame main body 1, a vehicle frame base 2 is fixedly provided on the lower side surface of the vehicle frame main body 1, the vehicle frame base 2 includes a base pillar 32 and a base support plate 33, the upper end of the base pillar 32 is fixedly provided on the lower side surface of the vehicle frame main body 1, the lower end of the base pillar 32 is fixedly provided with a base support plate 33, and the base support plate 33 supports on the ground, so that the vehicle frame base 2 can support the vehicle frame main body 1. An erection arm 8 is hinged on the upper side surface of the vehicle frame main body 1, a hydraulic rod 13 is hinged between the erection arm 8 and the vehicle frame main body 1, when the hydraulic rod 13 is in a contracted state, the erection arm 8 is arranged horizontally, and when the hydraulic rod 13 is in an extended state, the erection arm 8 is arranged vertically. The hydraulic rod 13 belongs to the prior art, and its specific structure and working principle will not be elaborated here. The two ends of the erection arm 8 are respectively a hinge end and a free end, the hinge end of the erection arm 8 is hinged on the upper side surface of the vehicle frame main body 1 through a pin shaft, a outer frame 9 is fixedly provided at the free end of the erection arm 8, an arc-shaped groove is provided on the outer frame 9 for accommodating the rocket body of the rocket model, a first clamping assembly 10 is provided on the outer frame 9, a second clamping assembly 11 is provided at the hinge end of the erection arm 8, and the outer frame 9, the first clamping assembly 10 and the second clamping assembly 11 are all located on the side of the erection arm 8 away from the vehicle frame main body 1.

[0024] The hydraulic rod 13 is located on the side of the erection arm 8 close to the vehicle frame main body 1, while the outer frame 9, the first clamping assembly 10 and the second clamping assembly 11 are all located on the side of the erection arm 8 far from the vehicle frame main body 1. That is to say, the overall structure jointly formed by the outer frame 9 and the first clamping assembly 10 and the hydraulic rod 13 are respectively located on the opposite sides of the erection arm 8, and the second clamping assembly 11 and the hydraulic rod 13 are also respectively located on the opposite sides of the erection arm 8.

[0025] As Figures 1 - 4 shown, in the rocket simulation erection device of the present invention, the first clamping assembly 10 includes two arc-shaped clamping rods 18 and two first hydraulic cylinders 15. The two arc-shaped clamping rods 18 are respectively hinged at both ends of the arc-shaped groove of the outer frame 9. The hinged part of each arc-shaped clamping rod 18 and the outer frame 9 is located between the two ends of the arc-shaped clamping rod 18. The two first hydraulic cylinders 15 are fixedly arranged on the outer frame 9 and are arranged in one-to-one correspondence with the two arc-shaped clamping rods 18. One ends of the two arc-shaped clamping rods 18 are respectively hinged to the piston rods 16 of their respective corresponding first hydraulic cylinders 15. The other ends of the two arc-shaped clamping rods 18 can move closer to or away from each other under the action of the two first hydraulic cylinders 15. When the other ends of the two arc-shaped clamping rods 18 move closer to each other, the other ends of the two arc-shaped clamping rods 18 can jointly form a circular clamping opening with the arc-shaped groove of the outer frame 9. The axis of the circular clamping opening is arranged in the same direction as the length direction of the erection arm 8.

[0026] In this embodiment, the outer frame 9 is an arc-shaped cylindrical structure. The inner concave outer side wall of the outer frame 9 forms the arc-shaped groove. The two arc-shaped clamping rods 18 are respectively inserted through the two barrel openings of the outer frame 9, that is, one ends of the two arc-shaped clamping rods 18 are respectively inserted into the two barrel openings of the outer frame 9, and the other ends of the two arc-shaped clamping rods 18 are both located outside the outer frame 9. The two arc-shaped clamping rods 18 are respectively hinged to the outer frame 9 through a rotating shaft 31. The rotating shaft 31 on each arc-shaped clamping rod 18 is located between the two ends of the arc-shaped clamping rod 18. One ends of the two arc-shaped clamping rods 18 are respectively fixedly provided with hinge seats 17 through bolts. The hinge seat 17 has two oppositely arranged hinge plates. Since the two first hydraulic cylinders 15 are arranged in one-to-one correspondence with the two arc-shaped clamping rods 18 (both of the two first hydraulic cylinders 15 are arranged inside the outer frame 9), the two first hydraulic cylinders 15 are also arranged in one-to-one correspondence with the two hinge seats 17. The piston rods 16 of the two first hydraulic cylinders 15 are respectively hinged between the two hinge plates of their respective corresponding hinge seats 17.

[0027] The concave sides of the two arc-shaped clamping rods 18 are both arranged towards the center of the arc-shaped groove. The two first hydraulic cylinders 15 are both located between one ends of the two arc-shaped clamping rods 18. When the piston rods 16 of the two first hydraulic cylinders 15 extend, they can drive the two arc-shaped clamping rods 18 to rotate around their respective rotating shafts 31. At this time, one ends of the two arc-shaped clamping rods 18 move away from each other. Since the rotating shaft 31 is located between the two ends of the arc-shaped clamping rod 18, the other ends of the two arc-shaped clamping rods 18 move closer to each other until the concave sides of the two arc-shaped clamping rods 18 and the arc-shaped groove of the outer frame 9 jointly form a circular clamping opening (that is, at this time, the center of the arc-shaped groove coincides with the center of the concave side of the arc-shaped clamping rod 18), that is, the two arc-shaped clamping rods 18 are closed. This circular clamping opening is used to clamp the body of the rocket model. On the contrary, when the piston rods 16 of the two first hydraulic cylinders 15 retract, they can drive one ends of the two arc-shaped clamping rods 18 to move closer to each other. At this time, the other ends of the two arc-shaped clamping rods 18 move away from each other, that is, the two arc-shaped clamping rods 18 open, which is convenient for placing the body on the arc-shaped groove of the outer frame 9.

[0028] There is enough space inside the outer frame 9 and at both ends of the barrel opening to allow the two arc-shaped clamping rods 18 to rotate around their respective rotating shafts 31.

[0029] As Figure 3 shown, in the rocket simulation erection device of the present invention, clamping rod grooves 19 are provided on the opposite two side surfaces of the other ends of the two arc-shaped clamping rods 18, that is, clamping rod grooves 19 are provided on the concave side surfaces of the other ends of each arc-shaped clamping rod 18. The connection line between the centers of the two clamping rod grooves 19 passes through the center of the circular clamping opening.

[0030] In this embodiment, when the two arc-shaped clamping rods 18 are closed, there is a gap between the other ends of the two arc-shaped clamping rods 18. If the clamping rod grooves 19 are not provided on the concave side surfaces of the arc-shaped clamping rods 18, then when the circular clamping opening clamps the body of the rocket, it is easy to cause the body of the rocket to deform, that is, the body of the rocket bulges towards the gap between the other ends of the two arc-shaped clamping rods 18. And the force applied to the body of the rocket at the concave side surfaces of the two arc-shaped clamping rods 18 arranged along the diameter direction of the body of the rocket on both sides of the gap is most likely to cause the body of the rocket to deform. Therefore, in order to prevent the body of the rocket from deforming to the greatest extent, clamping rod grooves 19 are respectively provided at the concave side surfaces of the two arc-shaped clamping rods 18 arranged along the diameter direction of the body of the rocket on both sides of the gap to prevent them from applying force to the body of the rocket. Since when the circular clamping opening clamps the body of the rocket, the body of the rocket is coaxially arranged with the circular clamping opening, therefore, when the two clamping rod grooves 19 are arranged along the diameter direction of the body of the rocket, the connection line between the centers of the two clamping rod grooves 19 also passes through the center of the circular clamping opening.

[0031] As Figure 4 、 5As shown, the rocket simulation erection device of the present invention, wherein the second clamping assembly 11 includes two sets of clamping members. The two sets of clamping members are respectively located on the opposite sides of the central connection line of the hinged end and the free end of the erection arm 8. The clamping member includes a second hydraulic cylinder 23 and a third hydraulic cylinder 28. The second hydraulic cylinder 23 and the third hydraulic cylinder 28 are respectively fixedly arranged on two support platforms 21. The two support platforms 21 are respectively fixedly arranged on the erection arm 8 through support columns 20. A baffle 27 is fixedly connected between the two support platforms 21. A first clamping plate 25 is vertically fixedly arranged on the piston rod 24 of the second hydraulic cylinder 23. A second clamping plate 26 is vertically fixedly arranged on the piston rod 29 of the third hydraulic cylinder 28. The first clamping plate 25 and the second clamping plate 26 are both abutted against the baffle 27. The first clamping plate 25 and the second clamping plate 26 are arranged oppositely. The second hydraulic cylinder 23 is arranged along the length direction of the erection arm 8 and the piston rod 24 of the second hydraulic cylinder 23 faces the free end of the erection arm 8. The third hydraulic cylinder 28 is arranged obliquely to the length direction of the erection arm 8 and the piston rod 29 of the third hydraulic cylinder 28 faces the hinged end of the erection arm 8. The distance between the two third hydraulic cylinders 28 gradually increases along the direction from the hinged end to the free end of the erection arm 8. The first clamping plate 25 and the second clamping plate 26 can move closer to or away from each other respectively under the action of the second hydraulic cylinder 23 and the third hydraulic cylinder 28.

[0032] When fixing the second hydraulic cylinder 23 on the support platform 21, a fixing seat 22 is fixedly arranged on the support platform 21 by bolts. The fixing seat 22 has two oppositely arranged fixing plates. One end of the cylinder body of the second hydraulic cylinder 23 is fixedly arranged between the two fixing plates by bolts and other fasteners. The other end of the cylinder body of the second hydraulic cylinder 23 is fixedly arranged on the support platform 21 by bolts and other fasteners. In this way, the second hydraulic cylinder 23 is fixed on the support platform 21. As for the way of fixing the third hydraulic cylinder 28 on the support platform 21, it is the same as that of the second hydraulic cylinder 23 and will not be elaborated here.

[0033] Two connectors are fixedly arranged on the outer side wall of the middle and lower sections of the rocket body. When the second clamping assembly 11 clamps the rocket body, the two sets of clamping members respectively clamp the two connectors. During specific clamping, the piston rod 24 of the second hydraulic cylinder 23 is extended, so the first clamping plate 25 slides along the baffle 27 away from the hinged end of the erection arm 8. At the same time, the piston rod 29 of the third hydraulic cylinder 28 is also extended, so the second clamping plate 26 slides along the baffle 27 towards the hinged end of the erection arm 8. That is, at this time, the first clamping plate 25 and the second clamping plate 26 move closer to each other under the action of the second hydraulic cylinder 23 and the third hydraulic cylinder 28 respectively until the connector is clamped between the first clamping plate 25, the second clamping plate 26 and the baffle 27. On the contrary, when the piston rod 24 of the second hydraulic cylinder 23 retracts, the first clamping plate 25 slides along the baffle 27 towards the hinged end of the erection arm 8. At the same time, when the piston rod 29 of the third hydraulic cylinder 28 retracts, the second clamping plate 26 slides along the baffle 27 away from the hinged end of the erection arm 8. That is, at this time, the first clamping plate 25 and the second clamping plate 26 move away from each other under the action of the second hydraulic cylinder 23 and the third hydraulic cylinder 28 respectively.

[0034] As Figure 1 , 2 shown, in the rocket simulation erection device of the present invention, a fourth hydraulic cylinder 5 is fixedly arranged on the outer side of the periphery of the vehicle frame main body 1. The cylinder body of the fourth hydraulic cylinder 5 is fixedly arranged on the vehicle frame main body 1. The piston rod 30 of the fourth hydraulic cylinder 5 is arranged downward. A support base 6 is fixedly arranged on the piston rod 30 of the fourth hydraulic cylinder 5, and the support base 6 is disc-shaped. One end of a steel cable 3 is connected to the outer side of the periphery of the vehicle frame main body 1, and the other end of the steel cable 3 is connected to a turnbuckle 4.

[0035] In the rocket simulation erection device of the present invention, the vehicle frame main body 1 is a rectangular frame structure. Frame bases 2 are respectively fixedly arranged at the four corners of the lower side surface of the vehicle frame main body 1. Fourth hydraulic cylinders 5 are respectively fixedly arranged at the four corners of the outer side of the periphery of the vehicle frame main body 1. One end of a steel cable 3 is respectively connected to the four corners of the outer side of the periphery of the vehicle frame main body 1.

[0036] During use, the main frame body 1 is supported by the frame base 2. Since a high level of horizontality is required for the main frame body 1 during launch, if the main frame body 1 cannot maintain horizontality relying solely on the frame base 2, for example, when the launch site is uneven, it is necessary to adjust the level of the main frame body 1 by means of the lifting of the fourth hydraulic cylinder 5 (that is, let the support base 6 support on the ground, and then extend the piston rod 30 of the fourth hydraulic cylinder 5, then the fourth hydraulic cylinder 5 rises, and the main frame body 1 also rises accordingly. On the contrary, let the piston rod 30 of the fourth hydraulic cylinder 5 retract, then the fourth hydraulic cylinder 5 descends, and the main frame body 1 also descends accordingly. In this way, the lifting of the four fourth hydraulic cylinders 5 can be adjusted respectively to level the main frame body 1), so as to facilitate the launch of the rocket model. After the main frame body 1 is leveled, in order to keep the main frame body 1 in this state and make the erection arm 8 more stable during the erection process, the main frame body 1 can be fixed by the steel rope 3 and the turnbuckle 4, that is, connect the turnbuckle 4 with the fixing piece on the launch site, and then adjust the tension of the steel rope 3 through the turnbuckle 4.

[0037] As Figure 1 、 2 、shown in 4, the rocket simulation erection device of the present invention, wherein the erection arm 8 is of a frame structure, and a connecting frame 12 is fixedly provided on the side of the erection arm 8 away from the main frame body 1. One end of the hydraulic rod 13 is hinged to the main frame body 1 through a pin shaft, and the other end of the hydraulic rod 13 passes through the erection arm 8 and is hinged to the connecting frame 12 through a pin shaft. In order to keep the erection arm 8 stable during the erection process, one end of the hydraulic rod 13 is hinged to the middle part of the upper side of the main frame body 1, the other end of the hydraulic rod 13 is hinged to the middle part of the connecting frame 12, and the connecting frame 12 is also located in the middle part of the erection arm 8. In this way, when the hydraulic rod 13 expands and contracts, the main frame body 1 and the erection arm 8 are evenly stressed, and the erection arm 8 can maintain a stable state.

[0038] As Figure 1 、 4 shown in, the rocket simulation erection device of the present invention, wherein the connecting frame 12 is rectangular, the length direction of the connecting frame 12 is arranged in the same direction as the width direction of the erection arm 8, and side plates 14 are fixedly connected between the two ends in the length direction of the connecting frame 12 and the erection arm 8 respectively. The side plates 14 can further enhance the strength of the connecting frame 12.

[0039] As Figure 1 、 2 shown in, the rocket simulation erection device of the present invention, wherein a control box 7 is fixedly provided on the main frame body 1. Control equipment for controlling the hydraulic rod 13 and each hydraulic cylinder in the erection device is installed in the control box 7.

[0040] When the rocket simulation erection device of the present invention is in use, the vehicle frame main body 1 is placed on the launch site, and the vehicle frame main body 1 can be leveled by the fourth hydraulic cylinder 5 according to the specific conditions of the site. Then, the vehicle frame main body 1 is fixed by the steel wire rope 3 and the turnbuckle 4, and the hydraulic rod 13 is in a contracted state, that is, the erection arm 8 is arranged horizontally, and the two arc-shaped clamping rods 18 in the first clamping assembly 10 are also in an open state, and the first clamping plate 25 and the second clamping plate 26 in the second clamping assembly 11 are also far away from each other to the maximum distance. Then, the rocket model is placed on the erection arm 8, and the upper part of the rocket model is located in the arc-shaped groove of the outer frame 9, and the connecting piece on the middle and lower parts of the rocket model is located between the first clamping plate 25, the second clamping plate 26 and the baffle 27. Then, the first hydraulic cylinder 15 is started, and the two arc-shaped clamping rods 18 are closed until the rocket body is clamped in the circular clamping opening jointly formed by the two arc-shaped clamping rods 18 and the arc-shaped groove of the outer frame 9 (at this time, the arc-shaped groove and the inner concave side surfaces of the two arc-shaped clamping rods 18 are both in contact with the rocket body, so as to clamp the rocket body. Since there are clamping rod grooves 19 on the inner concave side surfaces of the arc-shaped clamping rods 18, the deformation of the rocket body will be greatly reduced). At the same time, the second hydraulic cylinder 23 and the third hydraulic cylinder 28 are started, and the first clamping plate 25 and the second clamping plate 26 are made to move closer to each other until the connecting piece is clamped between the first clamping plate 25, the second clamping plate 26 and the baffle 27. In this way, the upper part of the rocket body is clamped by the first clamping assembly 10, and the middle and lower parts of the rocket body are clamped and fixed by the second clamping assembly 11. Since the second clamping assembly 11 does not directly contact the outer side wall of the rocket body, the deformation of the rocket body during the erection process can be reduced. Then, the hydraulic rod 13 is changed from the contracted state to the extended state, so the hydraulic rod 13 erects the entire erection arm 8, and the rocket model also follows the erection arm 8 to complete the erection, and then the launch can be carried out. It can be seen that the present invention can conveniently clamp and fix the entire rocket model, and will not cause deformation to the outer wall of the rocket model during the erection process, so that the rocket model is more stable and safe during erection.
