Description

Technical Field

[0001] This utility model relates to the field of rocket simulation erection technology, and in particular to a rocket simulation erection device. Background Technology

[0002] In the aerospace field, rocket launch and testing modes mainly include the "one-horizontal-two-vertical" mode, the "three-vertical" mode, and the "three-horizontal" mode. "One-horizontal-two-vertical" refers to horizontal transport, vertical assembly, and vertical testing; "three-vertical" refers to vertical transport, vertical assembly, and vertical testing; and "three-horizontal" refers to horizontal assembly, horizontal testing, and horizontal transport. Compared to the "one-horizontal-two-vertical" and "three-vertical" modes, the "three-horizontal" mode completes all assembly and testing within the technical workshop. Because it is unaffected by weather, assembly and testing times are relatively predictable, and it eliminates the need for high-rise tooling to support assembly and testing, reducing the height requirements of the technical workshop. It boasts advantages such as a low center of gravity, high efficiency, and good mobility. After the entire rocket is transported horizontally to the launch position, it can be quickly erected, shortening the time a single rocket occupies the launch range and improving range utilization. Therefore, the "three-horizontal" mode is a commonly used launch and testing mode. This mode requires transport equipment to move the rocket to the erection position, and then uses an erection device to erect the horizontal rocket to a vertical position.

[0003] To identify and resolve potential problems with rockets in the three launch modes mentioned above, simulated launches are often conducted. This involves using a simulated launcher to launch a rocket model. The rocket model uses the same materials as the actual rocket, but is smaller in size. Since both the rocket model and the actual rocket are made of composite materials, although composite materials offer advantages in weight reduction when used in rocket casings compared to conventional materials, they are prone to deformation, resulting in poor stability during the launch process and potential safety issues. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a rocket simulation erection device, which 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 as to make the rocket model more stable and safer when erecting.

[0005] This utility model relates to a rocket simulation erection device, comprising a frame body, a frame base fixedly mounted on the lower side of the frame body, the frame base including a base support column and a base support plate, the upper end of the base support column being fixedly mounted on the lower side of the frame body, and the lower end of the base support column being fixedly mounted on the base support plate. An erection arm is hinged to the upper side of the frame body, and a hydraulic rod is hinged between the erection arm and the frame body. The two ends of the erection arm are a hinged end and a free end, respectively. The hinged end of the erection arm is hinged to the upper side of the frame body, and an outer frame is fixedly mounted on the free end of the erection arm. The outer frame has an arc-shaped groove and a first clamping assembly. The hinged end of the erection arm has a second clamping assembly. The outer frame, the first clamping assembly, and the second clamping assembly are all located on the side of the erection arm away from the frame body.

[0006] This utility model relates to a rocket simulation erection device, wherein the first clamping assembly includes two arc-shaped clamping rods and two first hydraulic cylinders. The two arc-shaped clamping rods are respectively hinged to both ends of the arc-shaped groove of the outer frame. The hinge portion of each arc-shaped clamping rod is located between the two ends of the arc-shaped clamping rod. The two first hydraulic cylinders are fixed on the outer frame and are arranged one-to-one with the two arc-shaped clamping rods. One end of each arc-shaped clamping rod is hinged to the piston rod of its corresponding first hydraulic cylinder. The other ends of the two arc-shaped clamping rods can move closer or further apart under the action of the two first hydraulic cylinders. When the other ends of the two arc-shaped clamping rods move closer together, the other ends of the two arc-shaped clamping rods can form a circular clamping opening together with the arc-shaped groove of the outer frame. The axis of the circular clamping opening is arranged in the same direction as the length direction of the erection arm.

[0007] The present invention relates to a rocket simulation erection device, wherein the two arc-shaped clamping rods are provided with clamping rod grooves on two opposite sides at the other end, and the line connecting the centers of the two clamping rod grooves passes through the center of the circular clamping opening.

[0008] This utility model relates to a rocket simulation erection device, wherein the second clamping assembly includes two sets of clamping members, which are located on opposite sides of the line connecting the center of the hinge end and the free end of the erection arm. Each clamping member includes a second hydraulic cylinder and a third hydraulic cylinder, which are respectively fixedly mounted on two support platforms. The two support platforms are respectively fixed to the erection arm by support columns, and a baffle is fixedly connected between the two support platforms. A first clamping plate is vertically fixed to the piston rod of the second hydraulic cylinder, and a second clamping plate is vertically fixed to the piston rod of the third hydraulic cylinder. The first and second clamping plates abut against the baffle. The first and second clamping plates are arranged opposite each other. The second hydraulic cylinder is arranged along the length of the erecting arm and the piston rod of the second hydraulic cylinder is arranged toward the free end of the erecting arm. The third hydraulic cylinder is arranged inclined along the length of the erecting arm and the piston rod of the third hydraulic cylinder is arranged toward the hinge end of the erecting arm. The distance between the two third hydraulic cylinders gradually increases along the direction from the hinge end of the erecting arm to the free end. The first and second clamping plates can move closer or further apart from each other under the action of the second and third hydraulic cylinders, respectively.

[0009] This utility model relates to a rocket simulation erection device, wherein a fourth hydraulic cylinder is fixedly installed on the outer periphery of the main frame body, the cylinder body of the fourth hydraulic cylinder is fixedly installed on the main frame body, the piston rod of the fourth hydraulic cylinder is arranged downward, and a support base is fixedly installed on the piston rod of the fourth hydraulic cylinder.

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

[0011] This utility model relates to a rocket simulation erection device, wherein the erection arm is a frame structure, and a connecting frame is fixedly provided on the side of the erection arm away from the vehicle frame body. One end of the hydraulic rod is hinged to the vehicle frame body, and the other end of the hydraulic rod passes through the erection arm and is hinged to the connecting frame.

[0012] The present invention relates to a rocket simulation erection device, 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 to the erection arm at both ends of the length direction of the connecting frame.

[0013] This utility model relates to a rocket simulation erection device, wherein the main body of the frame is a rectangular frame structure, and a frame base is fixedly installed at each of the four corners of the lower side of the main body of the frame. A fourth hydraulic cylinder is fixedly installed at each of the four corners of the outer perimeter of the main body of the frame, and one end of a steel rope is connected to each of the four corners of the outer perimeter of the main body of the frame.

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

[0015] The difference between this rocket simulation erection device and existing technologies lies in that, during use, the hydraulic rod is in a retracted state, meaning the erection arm is arranged horizontally. The rocket model is placed on the erection arm, with its upper section positioned within the arc-shaped groove of the outer frame. A first clamping assembly then engages with the outer frame to clamp the upper section of the rocket. A connecting piece is fixed to the outer wall of the lower middle section of the rocket, and a second clamping assembly clamps this connecting piece, thus securing the lower middle section of the rocket. Since the second clamping assembly does not directly contact the outer wall of the rocket, deformation during erection is reduced. Next, the hydraulic rod extends from its retracted state, raising the entire erection arm. The rocket model then follows the extension arm and is ready for launch. Therefore, this invention conveniently clamps and secures the entire rocket model without deforming its outer wall during erection, resulting in a more stable and safer erection process.

[0016] The present invention will be further described below with reference to the accompanying drawings. Attached Figure Description

[0023] like Figure 1 As shown, and in combination Figure 2-5 As shown, this utility model's rocket simulation erection device includes a frame body 1. A frame base 2 is fixedly mounted on the lower side of the frame body 1. The frame base 2 includes a base support column 32 and a base support plate 33. The upper end of the base support column 32 is fixedly mounted on the lower side of the frame body 1, and the lower end of the base support column 32 is fixedly mounted on the base support plate 33, which supports the ground. Thus, the frame base 2 can support the frame body 1. An erection arm 8 is hinged to the upper side of the frame body 1. A hydraulic rod 13 is hinged between the erection arm 8 and the frame body 1. When the hydraulic rod 13 is in a retracted state, the erection arm 8 is arranged horizontally; when the hydraulic rod 13 is in an extended state, the erection arm 8 is arranged vertically. The hydraulic rod 13 is prior art, and its specific structure and working principle will not be described in detail. The two ends of the erecting arm 8 are a hinged end and a free end, respectively. The hinged end of the erecting arm 8 is hinged to the upper side of the frame body 1 by a pin. The free end of the erecting arm 8 is fixedly provided with an outer frame 9. The outer frame 9 is provided with an arc-shaped groove for accommodating the rocket body of the rocket model. The outer frame 9 is provided with a first clamping assembly 10. The hinged end of the erecting arm 8 is provided with a second clamping assembly 11. The outer frame 9, the first clamping assembly 10 and the second clamping assembly 11 are all located on the side of the erecting arm 8 away from the frame body 1.

[0024] The hydraulic rod 13 is located on the side of the erecting arm 8 closer to the frame 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 erecting arm 8 away from the frame body 1. That is to say, the overall structure formed by the outer frame 9 and the first clamping assembly 10 and the hydraulic rod 13 are located on opposite sides of the erecting arm 8, and the second clamping assembly 11 and the hydraulic rod 13 are also located on opposite sides of the erecting arm 8.

[0025] like Figure 1-4As shown, the rocket simulation erection device of this utility model includes a first clamping assembly 10 comprising two arc-shaped clamping rods 18 and two first hydraulic cylinders 15. The two arc-shaped clamping rods 18 are respectively hinged to both ends of the arc-shaped groove of the outer frame 9. The hinge point 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 mounted on the outer frame 9 and are arranged one-to-one with the two arc-shaped clamping rods 18. One end of each arc-shaped clamping rod 18 is hinged to the piston rod 16 of its corresponding first hydraulic cylinder 15. The other ends of the two arc-shaped clamping rods 18 can move closer or further apart 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 form a circular clamping opening together 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 concave outer side wall of the outer frame 9 forms the arc-shaped groove. The arc-shaped clamping rods 18 are respectively inserted at the two openings of the outer frame 9. That is, one end of the two arc-shaped clamping rods 18 is inserted into the two openings of the outer frame 9, and the other end of the two arc-shaped clamping rods 18 is located outside the outer frame 9. The two arc-shaped clamping rods 18 are respectively hinged to the outer frame 9 by a pivot 31. The pivot 31 on each arc-shaped clamping rod 18 is located between the two ends of the arc-shaped clamping rod 18. One end of each of the two arc-shaped clamping rods 18 is fixed with a hinge seat 17 by bolts. The hinge seat 17 has two hinge plates arranged opposite to each other. Since the two first hydraulic cylinders 15 are arranged in a one-to-one correspondence with the two arc-shaped clamping rods 18 (the two first hydraulic cylinders 15 are arranged inside the outer frame 9), the two first hydraulic cylinders 15 are also arranged in a 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 hinge seats 17 by pins.

[0027] The concave sides of the two arc-shaped clamping rods 18 are arranged facing the center of the arc-shaped groove. The two first hydraulic cylinders 15 are located between one end 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 end of the two arc-shaped clamping rods 18 moves away from each other. Since the rotating shaft 31 is located between the two ends of the arc-shaped clamping rods 18, the other end of the two arc-shaped clamping rods 18 moves 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 together 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 rocket body of the rocket model. Conversely, when the piston rods 16 of the two first hydraulic cylinders 15 retract, they can drive one end of the two arc-shaped clamping rods 18 to move closer to each other, while the other ends of the two arc-shaped clamping rods 18 move further apart. That is, the two arc-shaped clamping rods 18 open, which makes it easier to place the arrow 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 cylinder opening to allow the two arc-shaped clamps 18 to rotate around their respective axes 31.

[0029] like Figure 3 As shown, in the rocket simulation erection device of this utility model, there are clamping rod grooves 19 on two opposite sides of the other end of the two arc-shaped clamping rods 18, that is, clamping rod grooves 19 are provided on the concave side of the other end of each arc-shaped clamping rod 18, and the line connecting 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 clamping rod grooves 19 are not provided on the concave side of the arc-shaped clamping rods 18, the circular clamping opening will easily cause the arrow body to deform when clamping it. That is, the arrow body will bulge out of the gap between the other ends of the two arc-shaped clamping rods 18. The force applied to the arrow body at the concave side of the two arc-shaped clamping rods 18 arranged on opposite sides of the gap and along the diameter direction of the arrow body is most likely to cause the arrow body to deform. Therefore, in order to prevent the arrow body from deforming to the greatest extent, clamping rod grooves 19 are respectively provided on the concave side of the two arc-shaped clamping rods 18 arranged on opposite sides of the gap and along the diameter direction of the arrow body, so that no force is applied to the arrow body. Since the arrow body and the circular clamping opening are arranged coaxially when clamping the arrow body at the circular clamping opening, when the two clamping rod grooves 19 are arranged along the diameter direction of the arrow body, the line connecting the centers of the two clamping rod grooves 19 also passes through the center of the circular clamping opening.

[0031] like Figure 4 , 5As shown, the rocket simulation erection device of this utility model includes a second clamping assembly 11 comprising two sets of clamping components. These two sets of clamping components are located on opposite sides of the line connecting the center of the hinge end and the center of the free end of the erection arm 8. Each clamping component 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 mounted on two support platforms 21. The two support platforms 21 are respectively fixedly mounted on the erection arm 8 via support columns 20. A baffle 27 is fixedly connected between the two support platforms 21. A first clamping plate 25 is vertically fixedly mounted on the piston rod 24 of the second hydraulic cylinder 23, and a second clamping plate 26 is vertically fixedly mounted on the piston rod 29 of the third hydraulic cylinder 28. The first clamping plate 25 and the second clamping plate 26 both abut against the baffle 27. The first clamping plate 25 and the second clamping plate 26 are arranged opposite each other. The second hydraulic cylinder 23 is arranged along the length direction of the erecting arm 8 and the piston rod 24 of the second hydraulic cylinder 23 is arranged toward the free end of the erecting arm 8. The third hydraulic cylinder 28 is arranged inclined along the length direction of the erecting arm 8 and the piston rod 29 of the third hydraulic cylinder 28 is arranged toward the hinge end of the erecting arm 8. The distance between the two third hydraulic cylinders 28 gradually increases along the direction from the hinge end of the erecting arm 8 to the free end. The first clamping plate 25 and the second clamping plate 26 can move closer to each other or further away from each other under the action of the second hydraulic cylinder 23 and the third hydraulic cylinder 28, respectively.

[0032] When fixing the second hydraulic cylinder 23 to the support platform 21, a fixing seat 22 is bolted to the support platform 21. The fixing seat 22 has two oppositely arranged fixing plates. One end of the cylinder body of the second hydraulic cylinder 23 is fixed between the two fixing plates by bolts or other fasteners, and the other end of the cylinder body of the second hydraulic cylinder 23 is fixed to the support platform 21 by bolts or other fasteners. In this way, the second hydraulic cylinder 23 is fixed to the support platform 21. The method of fixing the third hydraulic cylinder 28 to the support platform 21 is the same as that of the second hydraulic cylinder 23, and will not be described in detail here.

[0033] Two connectors are fixed on the outer wall of the middle and lower section of the arrow body. When the second clamping assembly 11 clamps the arrow body, the two clamping assemblies clamp the two connectors respectively. During the clamping process, the piston rod 24 of the second hydraulic cylinder 23 extends, and the first clamping plate 25 slides away from the hinge end of the erecting arm 8 along the baffle 27. At the same time, the piston rod 29 of the third hydraulic cylinder 28 extends, and the second clamping plate 26 slides closer to the hinge end of the erecting arm 8 along the baffle 27. 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 connectors are clamped between the first clamping plate 25, the second clamping plate 26 and the baffle 27. Conversely, when the piston rod 24 of the second hydraulic cylinder 23 retracts, the first clamping plate 25 slides along the baffle 27 towards the hinge end of the erecting 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 hinge end of the erecting 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] like Figure 1 , 2 As shown, this utility model relates to a rocket simulation erection device, wherein a fourth hydraulic cylinder 5 is fixedly installed on the outer periphery of the frame body 1. The cylinder body of the fourth hydraulic cylinder 5 is fixedly installed on the frame body 1, and the piston rod 30 of the fourth hydraulic cylinder 5 is arranged downwards. A support base 6, which is disc-shaped, is fixedly installed on the piston rod 30 of the fourth hydraulic cylinder 5. One end of a steel rope 3 is connected to the outer periphery of the frame body 1, and the other end of the steel rope 3 is connected to a turnbuckle 4.

[0035] The present invention relates to a rocket simulation erection device, wherein the main body 1 of the frame is a rectangular frame structure, the four corners of the lower side of the main body 1 are respectively fixed with a frame base 2, the four corners of the outer perimeter of the main body 1 are respectively fixed with a fourth hydraulic cylinder 5, and one end of a steel rope 3 is connected to the four corners of the outer perimeter of the main body 1.

[0036] During use, the main body 1 of the chassis is supported by the chassis base 2. Since the levelness requirement of the main body 1 of the chassis is high during launch, if the main body 1 of the chassis cannot be kept level by the chassis base 2 alone, for example, when the launch site is uneven, it is necessary to use the lifting and lowering of the fourth hydraulic cylinder 5 to level the main body 1 of the chassis (that is, let the support base 6 support the ground, then let the piston rod 30 of the fourth hydraulic cylinder 5 extend, then the fourth hydraulic cylinder 5 rises, and the main body 1 of the chassis also rises; conversely, let the piston rod 30 of the fourth hydraulic cylinder 5 retract, then the fourth hydraulic cylinder 5 falls, and the main body 1 of the chassis also falls. In this way, the lifting and lowering of the four fourth hydraulic cylinders 5 can be adjusted to level the main body 1 of the chassis, so as to facilitate the launch of the rocket model. After the main body 1 of the vehicle frame is leveled, in order to keep the main body 1 of the vehicle frame in this state and make the erecting arm 8 more stable during the erection process, the main body 1 of the vehicle frame can be fixed by steel rope 3 and turnbuckle 4. That is, the turnbuckle 4 is connected to the fixing parts on the launch site, and then the tension of the steel rope 3 can be adjusted by the turnbuckle 4.

[0037] like Figure 1 , 2 As shown in Figure 4, the rocket simulation erection device of this utility model includes an erection arm 8 with a frame structure. A connecting frame 12 is fixedly installed on the side of the erection arm 8 away from the vehicle frame body 1. One end of the hydraulic rod 13 is hinged to the vehicle frame body 1 via a pin, and the other end of the hydraulic rod 13 passes through the erection arm 8 and is hinged to the connecting frame 12 via a pin. To ensure the stability of the erection arm 8 during erection, one end of the hydraulic rod 13 is hinged to the center of the upper side of the vehicle frame body 1, and the other end of the hydraulic rod 13 is hinged to the center of the connecting frame 12, which is also located in the center of the erection arm 8. Thus, when the hydraulic rod 13 extends or retracts, the vehicle frame body 1 and the erection arm 8 are subjected to balanced forces, allowing the erection arm 8 to maintain a stable state.

[0038] like Figure 1 , 4 As shown, the present invention relates to a rocket simulation erection device, wherein the connecting frame 12 is rectangular, and the length direction of the connecting frame 12 is arranged in the same direction as the width direction of the erection arm 8. Side plates 14 are fixedly connected to the erection arm 8 at both ends of the connecting frame 12 along its length. The side plates 14 further enhance the strength of the connecting frame 12.

[0039] like Figure 1 , 2 As shown, this utility model relates to a rocket simulation erection device, wherein a control box 7 is fixedly mounted on the main frame 1. The control box 7 contains control equipment for controlling the hydraulic rods 13 and the actions of each hydraulic cylinder in the erection device.

[0040] When using this rocket simulation erection device, the main body 1 of the vehicle frame is placed at the launch site. Depending on the site conditions, the main body 1 can be leveled using the fourth hydraulic cylinder 5. Then, the main body 1 is fixed using steel cables 3 and turnbuckles 4. The hydraulic rod 13 is in a retracted state, meaning the erection arm 8 is arranged horizontally. 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 moved as far apart as possible. The rocket model is then placed on the erection arm 8, with the upper section of the rocket model positioned within the arc-shaped groove of the outer frame 9. The connecting piece on the lower middle section of the rocket model is positioned between the first clamping plate 25, the second clamping plate 26, and the baffle 27. The first hydraulic cylinder 15 is then activated, causing the two arc-shaped clamping rods 18 to close, until the rocket body is clamped between the two arc-shaped clamping rods 18 and the arc-shaped groove of the outer frame 9. Within the circular clamping opening formed by the two components (at this time, the concave sides of the arc-shaped groove and the two arc-shaped clamping rods 18 abut against the rocket body, thereby clamping the rocket body tightly; since there is a clamping rod groove 19 on the concave side of the arc-shaped clamping rod 18, the deformation of the rocket body will be greatly reduced), the second hydraulic cylinder 23 and the third hydraulic cylinder 28 are activated simultaneously, causing the first clamping plate 25 and the second clamping plate 26 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 section of the rocket body is clamped by the first clamping assembly 10, and the middle and lower sections 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 wall of the rocket body, it can reduce the deformation of the rocket body during the erection process. Then, the hydraulic rod 13 is changed from the contracted state to the extended state, and the hydraulic rod 13 raises the entire erecting arm 8. The rocket model is also erected along with the erecting arm 8, and it can be launched. Therefore, this utility model 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, thus making the rocket model more stable and safer when erecting.
