Description

Technical Field

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

[0002] In the aerospace field, the main test and launch modes for rockets are the one-horizontal-two-vertical mode, the three-vertical mode, and the three-horizontal mode. The one-horizontal-two-vertical mode refers to horizontal transportation, vertical assembly, and vertical testing, the three-vertical mode refers to vertical transportation, vertical assembly, and vertical testing, and the three-horizontal mode refers to horizontal assembly, horizontal testing, and horizontal transportation. Compared with the one-horizontal-two-vertical mode and the three-vertical mode, in the three-horizontal mode, all assembly and testing of the rocket body are completed in the technical workshop. Because it is not affected by weather, the assembly and testing time is relatively fixed, and no high-rise tooling is required to support assembly and testing, which reduces the height requirements for the technical workshop. It has the advantages of a low center of mass, high efficiency, and good maneuverability. After the entire rocket is transported horizontally to the launch station, it can be quickly erected, shortening the time that a single rocket body occupies the range and helping to improve the utilization rate of the range. Therefore, the three-horizontal mode is a commonly used test and launch mode. In this mode, transportation equipment is required to transport the rocket to the erection position, and then the erection device is used to erect the horizontal rocket to a vertical state.

[0003] In order to discover and solve problems existing in the rocket in the above three test and launch modes in advance, the rocket is often subjected to simulated erection and launch, that is, a simulated 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 the actual rocket. Since both the rocket model and the actual rocket are made of composite materials, compared with conventional materials, although composite materials are more advantageous in reducing weight when used in rocket shells, composite materials are easy to deform, the erection process is not smooth, and safety problems are prone to occur. Summary of the Invention

The first and second clamping plates are both against the baffle, and the first and second clamping plates are arranged opposite to each other. The second hydraulic cylinder is arranged along the length direction 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 obliquely to the length direction of the erecting arm and the piston rod of the third hydraulic cylinder is arranged toward the hinged end of the erecting arm.

[0010] The rocket simulation erection device of the present invention comprises the following steps: one end of a steel rope is connected to the outer sides of the four sides of the frame body, and the other end of the steel rope is connected to a turnbuckle bolt.

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

[0023] like Figure 1 As shown, combined with Figure 2-5 As shown, the rocket simulation erection device of the present invention includes a frame body 1, a frame base 2 is fixedly provided on the lower side of the frame body 1, and the frame base 2 includes a base support 32 and a base support plate 33. The upper end of the base support 32 is fixed on the lower side of the frame body 1, and the lower end of the base support 32 is fixedly provided with a base support plate 33. The base support plate 33 is supported on the ground, so that the frame base 2 can support the frame body 1. An erection arm 8 is hinged on the upper side of the frame body 1, and 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 in a horizontal direction. When the hydraulic rod 13 is in an extended state, the erection arm 8 is arranged in a vertical direction. The hydraulic rod 13 belongs to the prior art, and its specific structure and working principle are not described in detail. The two ends of the erecting arm 8 are respectively a hinged end and a free end. The hinged end of the erecting arm 8 is hinged to the upper side of the frame body 1 through a pin shaft. The free end of the erecting arm 8 is fixed with an outer frame 9. The outer frame 9 is provided with an arc-shaped groove. The arc-shaped groove is used to accommodate the 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 close 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. In other words, the overall structure jointly constituted by the outer frame 9 and the first clamping assembly 10 and the hydraulic rod 13 are respectively located on opposite sides of the erecting arm 8, and the second clamping assembly 11 and the hydraulic rod 13 are also respectively located on opposite sides of the erecting arm 8.

[0025] like Figure 1-4 As shown, the rocket simulation erection device of the present invention, wherein 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 the two ends of the arc-shaped groove of the outer frame 9, and 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 fixed on the outer frame 9 and are arranged one-to-one with the two arc-shaped clamping rods 18, one end of the two arc-shaped clamping rods 18 is respectively hinged to the piston rod 16 of the corresponding first hydraulic cylinder 15, and 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, and 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, and 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, and the concave outer side wall of the outer frame 9 forms the arc-shaped groove. The two tube openings of the outer frame 9 are respectively inserted with the arc-shaped clamping rods 18, that is, one end of the two arc-shaped clamping rods 18 are respectively inserted into the two tube 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, and 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 end of the two arc-shaped clamping rods 18 is respectively fixed with an articulated seat 17 by bolts. The articulated seat 17 has two relatively arranged articulated plates. Since the two first hydraulic cylinders 15 are arranged one-to-one with the two arc-shaped clamping rods 18 (the two first hydraulic cylinders 15 are both arranged inside the outer frame 9), the two first hydraulic cylinders 15 are also arranged one-to-one with the two articulated seats 17. The piston rods 16 of the two first hydraulic cylinders 15 are respectively hinged between the two articulated plates of their corresponding articulated seats 17 through pins.

[0027] The concave side surfaces of the two arc-shaped clamping rods 18 are arranged toward the center of the arc-shaped groove, and the two first hydraulic cylinders 15 are located between one ends of the two arc-shaped clamping rods 18. When the piston rods 16 of the two first hydraulic cylinders 15 are extended, the two arc-shaped clamping rods 18 can be driven 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 rods 18, the other ends of the two arc-shaped clamping rods 18 move toward each other until the concave side surfaces 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, the center of the arc-shaped groove coincides with the center of the concave side surface of the arc-shaped clamping rod 18 at this time), that is, the two arc-shaped clamping rods 18 are closed, and the 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 end 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 are opened, which can facilitate the placement of 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 barrel to allow the two arc-shaped clamping rods 18 to rotate around their respective rotation axes 31.

[0029] like Figure 3 As shown, the rocket simulation erection device of the present invention is provided with clamping rod grooves 19 on the two opposite side surfaces of the other end of the two arc-shaped clamping rods 18, that is, a clamping rod groove 19 is provided on the concave side surface 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, a gap exists 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, the circular clamping opening will easily deform the arrow body when clamping the arrow body. That is, the arrow body will convexly deform toward the gap between the other ends of the two arc-shaped clamping rods 18. The force exerted on the arrow body by the concave side surfaces of the two arc-shaped clamping rods 18 arranged on opposite sides of the gap and along the arrow body diameter is most likely to cause deformation of the arrow body. Therefore, in order to prevent deformation of the arrow body to the greatest extent, clamping rod grooves 19 are provided on the concave side surfaces of the two arc-shaped clamping rods 18 arranged on opposite sides of the gap and along the arrow body diameter so that no force is exerted on the arrow body. Since the arrow body is coaxially arranged with the circular clamping opening when clamping the arrow body, when the two clamping rod grooves 19 are arranged along the arrow body diameter, 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 erecting device of the present invention, wherein the second clamping assembly 11 includes two sets of clamping parts, and the two sets of clamping parts are respectively located on opposite sides of the center line connecting the hinged end and the free end of the erecting arm 8, and the clamping parts include a second hydraulic cylinder 23 and a third hydraulic cylinder 28, and the second hydraulic cylinder 23 and the third hydraulic cylinder 28 are respectively fixed on two supporting platforms 21, and the two supporting platforms 21 are respectively fixed on the erecting arm 8 through support columns 20, and a baffle 27 is fixedly connected between the two supporting platforms 21, and a first clamping plate 25 is vertically fixed on the piston rod 24 of the second hydraulic cylinder 23, and a second clamping plate 26 is vertically fixed on the piston rod 29 of the third hydraulic cylinder 28. The first clamping plate 25 and the second clamping plate 26 are both against the baffle 27, and the first clamping plate 25 and the second clamping plate 26 are arranged opposite to 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 obliquely to the length direction of the erecting arm 8 and the piston rod 29 of the third hydraulic cylinder 28 is arranged toward the hinged end of the erecting 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 erecting arm 8. The first clamping plate 25 and the second clamping plate 26 can move closer to or away from each other under the action of the second hydraulic cylinder 23 and the third hydraulic cylinder 28 respectively.

[0032] When securing the second hydraulic cylinder 23 to the support platform 21, a fixing base 22 is fixed to the support platform 21 via bolts. The fixing base 22 comprises two opposing fixing plates. One end of the cylinder body of the second hydraulic cylinder 23 is secured between the two fixing plates via bolts or other fasteners, while the other end of the cylinder body of the second hydraulic cylinder 23 is secured to the support platform 21 via bolts or other fasteners. This secures the second hydraulic cylinder 23 to the support platform 21. The method for securing the third hydraulic cylinder 28 to the support platform 21 is the same as that for the second hydraulic cylinder 23 and will not be further described here.

[0033] Two connecting parts are fixed on the outer side wall of the middle and lower sections of the arrow body. When the second clamping assembly 11 clamps the arrow body, the two sets of clamping parts clamp the two connecting parts respectively. During the specific clamping, the piston rod 24 of the second hydraulic cylinder 23 is extended, so that the first clamping plate 25 slides along the baffle 27 away from the hinged end of the erecting arm 8. At the same time, the piston rod 29 of the third hydraulic cylinder 28 is also extended, so that the second clamping plate 26 slides along the baffle 27 close to the hinged end of the erecting arm 8. That is, at this time, the first clamping plate 25 and the second clamping plate 26 approach each other under the action of the second hydraulic cylinder 23 and the third hydraulic cylinder 28 respectively until the connecting parts are 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 is retracted, the first clamping plate 25 slides along the baffle 27 towards the hinged end of the erecting arm 8. At the same time, when the piston rod 29 of the third hydraulic cylinder 28 is retracted, the second clamping plate 26 slides along the baffle 27 away from the hinged 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, the present invention provides a simulated rocket erection device, wherein a fourth hydraulic cylinder 5 is fixedly mounted on the outer periphery of the vehicle body 1. The cylinder body of the fourth hydraulic cylinder 5 is fixed to the vehicle body 1, and the piston rod 30 of the fourth hydraulic cylinder 5 is arranged downward. A disc-shaped support base 6 is fixed to 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 vehicle body 1, and the other end of the steel rope 3 is connected to a turnbuckle 4.

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

[0036] During use, the frame body 1 is supported by the frame base 2. Since the horizontality of the frame body 1 is required to be high during launch, if the frame body 1 cannot be kept level by relying solely on the frame base 2, for example, when the launch site is uneven, it is necessary to use the lifting of the fourth hydraulic cylinder 5 to level the frame body 1 (that is, let the supporting base 6 be supported on the ground, and then let the piston rod 30 of the fourth hydraulic cylinder 5 be extended, then the fourth hydraulic cylinder 5 rises, and the frame body 1 also rises; conversely, let the piston rod 30 of the fourth hydraulic cylinder 5 be retracted, then the fourth hydraulic cylinder 5 descends, and the frame body 1 also descends; in this way, the frame body 1 can be leveled by adjusting the lifting of the four fourth hydraulic cylinders 5 respectively) to facilitate the launch of the rocket model. After the frame body 1 is leveled, in order to keep the frame body 1 in this state so that the erection arm 8 is more stable during the erection process, the frame body 1 can be fixed by the steel rope 3 and the basket bolt 4, that is, the basket bolt 4 is connected to the fixing part on the launch site, and then the tension of the steel rope 3 is adjusted by the basket bolt 4.

[0037] like Figure 1 、 2 As shown in Figure 4, the rocket simulation erection device of the present invention, wherein the erection arm 8 is a frame-type structure, a connecting frame 12 is fixedly provided on the side of the erection arm 8 away from the frame body 1, one end of the hydraulic rod 13 is hinged to the frame body 1 through 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 through a pin. 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 of the upper side of the frame body 1, and the other end of the hydraulic rod 13 is hinged to the middle of the connecting frame 12, and the connecting frame 12 is also located in the middle of the erection arm 8. In this way, when the hydraulic rod 13 is extended or retracted, the frame body 1 and the erection arm 8 are subjected to balanced forces, and the erection arm 8 can maintain a stable state.

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

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

[0040] When the rocket simulation erection device of the present invention is in use, the frame body 1 is placed on the launch site, and the frame body 1 can be leveled by the fourth hydraulic cylinder 5 according to the specific conditions of the site, and then the frame body 1 is fixed by the steel rope 3 and the basket bolt 4, so that the hydraulic rod 13 is in a retracted state, that is, the erection arm 8 is arranged in the horizontal direction, 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 moved away from each other to the farthest distance, and then the rocket model is placed on the erection arm 8, and the upper part of the rocket model is located in the arc groove of the outer frame 9, and the connecting parts on the middle and lower parts of the rocket model are located between the first clamping plate 25, the second clamping plate 26 and the baffle 27, and then the first hydraulic cylinder 15 is started again to close the two arc-shaped clamping rods 18 until the rocket body is clamped between the two arc-shaped clamping rods 18 and the arc groove of the outer frame 9. The second and third hydraulic cylinders 23 and 28 are simultaneously activated to move the first and second clamping plates 25 and 26 closer to each other until the connecting piece is clamped between the first and second clamping plates 25, 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 a contracted state to an extended state, so that the hydraulic rod 13 erects the entire erection arm 8, and the rocket model also completes the erection following the erection arm 8, and can be launched. 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, thereby making the rocket model more stable and safer when erected.
