Description

Technical Field

[0001] This invention relates to the field of support and fixing technology, and in particular to a multi-degree-of-freedom rocket erector support. Background Technology The rocket erector is a crucial piece of equipment used during rocket launch to vertically elevate the rocket to the launch position. It must, within a specified time, elevate the rocket from a horizontal to a vertical position and precisely position it at launch. The primary function of the rocket erector support is to support the rocket and ensure its stable erection, while also providing necessary preparation for subsequent launch. Existing rocket erector supports have the following shortcomings: 1. Lack of freedom of adjustment capability, unable to adapt to arrow body deviation. The existing fixed support does not have the ability of freedom of adjustment, and can only provide fixed support. It cannot cope with the radial deviation (such as slight changes in the radial dimension of the arrow body, and offset of the installation posture) and axial deviation (such as changes in the axial position of the arrow body caused by the influence of gravity field and temperature field) that may occur during the assembly or use of the arrow body.

[0002] 2. Insufficient protection for the arrow body, which is prone to rigid damage. The existing fixed support does not mention the design of "soft protection" for the arrow body. If it is in direct rigid contact with the arrow body, the surface of the arrow body may be damaged due to collision or stress concentration during assembly and support.

[0003] 3. The environmental adaptability and load stability are relatively weak. Existing fixed brackets may experience component corrosion and functional failure in high humidity and corrosive environments, or pose safety hazards when in contact with cryogenic propellant media.

[0004] If the steel structure of the erecting frame sways at the end due to the long cantilever, it can easily lead to load imbalance, unstable support, and even affect the initial attitude of the rocket body.

[0005] 4. Low assembly flexibility and poor adaptability: The existing fixed support structure cannot adjust the installation position or attitude. When there are manufacturing errors or assembly deviations in the rocket body, or when connectors need to be avoided, the fixed support cannot adapt to the space requirements, which may lead to low rocket body assembly efficiency, or even require additional modifications to the support or rocket body structure.

Detailed Implementation

[0020] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0021] like Figure 1 , Figure 2 , Figure 3 As shown, an embodiment of the present invention provides a multi-degree-of-freedom rocket erector support, comprising: First translation mechanism 11, second translation mechanism 12, pusher 8, adapter frame 2, first fixed frame 31, second fixed frame 32, moving frame 4, first lifting mechanism 51, second lifting mechanism 52; The first translation mechanism 11 is slidably connected to the first transition part 21 of the transition frame 2, and the second translation mechanism 12 is slidably connected to the second transition part 22 of the transition frame 2; The pusher 8 is fixed between the first adapter 21 and the second adapter 22; The first fixing frame 31 is fixedly connected to the first adapter 21, and the second fixing frame 32 is fixedly connected to the second adapter 22; The first fixed frame 31 is slidably connected to the first moving part 41 of the moving frame 4, and the second fixed frame 32 is slidably connected to the second moving part 42 of the moving frame 4; The first lifting mechanism 51 is fixedly connected to the first moving part 41, and the second lifting mechanism 52 is fixedly connected to the second moving part 42; When the first lifting mechanism 51 and the second lifting mechanism 52 move upward synchronously, they drive the first moving part 41 and the second moving part 42 of the motion frame 4 to move upward synchronously; when the first lifting mechanism 51 and the second lifting mechanism 52 move downward synchronously, they drive the first moving part 41 and the second moving part 42 of the motion frame 4 to move downward synchronously. The first moving part 41 of the motion frame 4 is provided with a first support frame 61, and the second moving part 42 of the motion frame 4 is provided with a second support frame 62. The first support frame 61 and the second support frame 62 form a support space for supporting the rocket.

[0022] In this embodiment, as Figure 1 , Figure 2 , Figure 3 As shown, the first translation mechanism 11 and the second translation mechanism 12 of the multi-degree-of-freedom rocket erector support are both fixedly connected to the adapter frame 2, providing basic support for the entire multi-degree-of-freedom rocket erector support. The first translation mechanism 11 and the second translation mechanism 12 can move in parallel under the action of the pusher 8, so that the multi-degree-of-freedom rocket erector support can be adjusted in translation position as a whole. The first fixed frame 31 and the second fixed frame 32 are fixedly connected to the adapter frame 2. The first fixed frame 31 and the second fixed frame 32 are connected to the moving frame 4 through a sliding mechanism. The first moving part 41 and the second moving part 42 of the moving frame 4 are respectively sleeved on the outside of the first fixed frame 31 and the second fixed frame 32, and can slide on the first fixed frame 31 and the second fixed frame 32 to adjust the height. The first lifting mechanism 51 is fixedly connected to the first moving part 41 of the motion frame 4, and the second lifting mechanism 52 is fixedly connected to the second moving part 42 of the motion frame 4, providing external sliding power for the sliding of the motion frame 4; The support frame 6 includes a first support part and a second support part. The first support part is fixedly connected to the first moving part 41 of the moving frame 4, and the second support part is fixedly connected to the second moving part 42 of the moving frame 4. The tops of the first support part and the second support part are both arc-shaped and symmetrically arranged to form a support space for supporting the rocket body. It can fit the shape of the rocket and provide support for the rocket body. Preferably, the erector support is located 53m away from the tail pivot of the erector steel structure to support the rocket body and ensure the initial posture of the rocket body.

[0023] The first lifting mechanism 51 and the second lifting mechanism 52 are designed with a 500mm telescopic stroke to accommodate radial protective adjustments to the arrow body. The first translation mechanism 11 and the second translation mechanism 12 are designed with a 600mm travel stroke to reliably support the arrow body even when its physical properties change under the influence of gravity and temperature fields. A U-shaped notch with a width of 900mm and a length of 1000mm is provided in the center of the motion frame to provide installation space for the arrow body connector.

[0024] The solution of the present invention, by setting a first translation mechanism 11, a second translation mechanism 12, a first lifting mechanism 51, and a second lifting mechanism 52, can flexibly adjust the radial and lateral positions, adapt to deviations, and ensure reliable support. Existing fixed supports are prone to unstable support or failure to fit the arrow body in this scenario. By setting an arc-shaped support frame 6, the impact caused by rigid contact can be effectively buffered.

[0025] like Figure 4 As shown, in an optional embodiment of the present invention, both the first translation mechanism 11 and the second translation mechanism 12 include: Parallel guide rails 111; Each of the guide rails 111 is slidably connected to at least two sliders 112; The first transition part 21 and the second transition part 22 of the transition frame 2 are adjusted back and forth by sliding slider 112 on guide rail 111. When the pusher 8 drives the first transition part 21 and the second transition part 22 to translate, the first transition part 21 and the second transition part 22 are adjusted back and forth by sliding slider 112 on guide rail 111, thereby realizing the parallel movement of the multi-degree-of-freedom rocket erector support back and forth.

[0026] In this embodiment, as Figure 4 As shown, the first translation mechanism 11 and the second translation mechanism 12 are connected between the adapter frame 2 and the erecting steel structure. They are mainly applicable when the arrow body is in a vertical state and its position changes due to changes in the gravitational field and temperature field. The first translation mechanism 11 and the second translation mechanism 12 can adjust the erecting frame support to the initial support position of the arrow body through axial displacement, providing effective support to the arrow body and playing a protective role.

[0027] Since the first translation mechanism 11 and the second translation mechanism 12 are installed at the front end of the erecting frame steel structure, but because the cantilever of the erecting frame steel structure is relatively long, the end of the erecting frame steel structure will sway slightly under the influence of environmental factors. Therefore, the smoothness of the translation mechanism's operation, stability, and load capacity are required. In this embodiment, the first translation mechanism 11 and the second translation mechanism 12 adopt a technical solution of guide rail 111 and slider 112 cooperating. This technical solution has high motion stability and reliability under the tight cooperation of guide rail 111 and slider 112, and can also convert static friction into sliding friction, thereby improving the load capacity.

[0028] like Figure 5 As shown, in an optional embodiment of the present invention, both the first adapter portion 21 and the second adapter portion 22 of the adapter frame 2 include: First support beam 211; A second support beam 212 and a third support beam 213 are vertically and fixedly connected to the first support beam 211; A first connecting plate 214 is fixedly connected to the top surface of the end of the first support beam 211; The second connecting plate 216 is fixedly connected to the bottom surface of the first support beam 211; A third connecting plate 217 is fixedly connected to the end of the first support beam 211; Wherein, the first connecting plate 214 of the first adapter 21 and the first connecting plate 215 of the second adapter 22 are fixedly connected to the first fixed frame 31 and the second fixed frame 32, respectively. The second connecting plate 216 is fixedly connected to the first translation mechanism 11 and the second translation mechanism 12; the third connecting plate 217 is fixedly connected to the pusher 8.

[0029] In this embodiment, as Figure 5 As shown, the adapter frame 2 is a flat rectangular structure assembled and welded from standard flat steel plates, possessing high rigidity and strength. It is mainly used for connecting and fixing the first fixed frame 31, the second fixed frame 32, the first translation mechanism 11, the second translation mechanism 12, and the pusher 8. Simultaneously, it can evenly transfer the load onto the erecting frame steel structure, serving as a stable carrier and providing a better movement environment for the erecting frame support. Preferably, its length is 3630mm, its width is 760mm, and its height is 320mm.

[0030] like Figure 6 As shown, in an optional embodiment of the present invention, both the first fixing frame 31 and the second fixing frame 32 include: Flange plate 311 is fixedly connected to the adapter frame 2; The first frame 312 is fixedly connected to the flange plate 311; At least two guide grooves 313 are fixedly connected to the first frame 312, and the guide grooves 313 are slidably connected to the first moving part 41 or the second moving part 42 of the moving frame 4; The mounting base 314 is fixedly connected to the first frame 312. The mounting base 314 of the first fixed frame 31 is fixedly connected to the first lifting mechanism 51, and the mounting base 314 of the second fixed frame 32 is fixedly connected to the second lifting mechanism 52.

[0031] In this embodiment, as Figure 6 As shown, both the first fixed frame 31 and the second fixed frame 32 are frame structures, each equipped with a first frame body 312, which is respectively installed inside the first moving part 41 or the second moving part 42 of the moving frame 4. Both the first fixed frame 31 and the second fixed frame 32 are assembled and welded from standard rectangular steel pipes. Six sliding guide grooves 313 are designed on the outer side of the frame for motion guidance, adapting to the six sliding tracks of the moving frame to achieve telescopic functionality. A flange plate 311 is designed at the bottom of the first frame body 312, with elongated slotted holes for connection and fixation with the adapter frame 2. The slotted holes also allow for positional adjustment within a certain range. Preferably, the length of the first frame body 312 is 1220mm, the width is 880mm, and the height is 1470mm.

[0032] like Figure 7 As shown, in an optional embodiment of the present invention, the first moving part 41 and the second moving part 42 of the motion frame 4 both include: Track 411 is slidably connected to the first fixed frame 31 and the second fixed frame 32; A second frame 412 is fixedly connected to the track 411; a notch is provided between the first moving part 41 and the second moving part 42.

[0033] In this embodiment, as Figure 7 As shown, the motion frame 4 has a box-shaped structure with a U-shaped notch in the center. The first motion section 41 and the second motion section 42 are located on either side, and are assembled and welded from standard flat steel plates. The first motion section 41 and the second motion section 42 have a supporting frame 412 constructed from rectangular steel pipes to ensure the overall structural rigidity and strength. Six sliding rails are designed on the inner side of the rectangular steel pipes for motion guidance. Threaded holes are designed on the top and sides of the first motion section 41 and the second motion section 42 of the motion frame 4 for connection and fixation with the upper clamping mechanism and the supporting frame 6. Preferably, the length of the box-shaped structure of the motion frame 4 is 3500mm, the width is 960mm, and the height is 1475mm.

[0034] like Figure 10As shown, in an optional embodiment of the present invention, both the first lifting mechanism 51 and the second lifting mechanism 52 include: Box 511; A worm gear 512 is fixedly connected to the housing 511; the worm gear 512 is fixedly connected to the motor. The worm wheel 513 is meshed with the worm 512; The lead screw 514 is threadedly connected to the worm gear 513; A lifting nut 515 is connected to the lead screw 514, and the lifting nut 515 is fixedly connected to the first moving part 41 or the second moving part 42 of the moving frame 4.

[0035] In this embodiment, as Figure 10 As shown, the first lifting mechanism 51 is connected to the first fixed frame 31 and is fixedly connected to the first moving part 41; the second lifting mechanism 52 is connected to the second fixed frame 32 and is fixedly connected to the second moving part 42. After the arrow body is positioned to the initial posture, the first lifting mechanism 51 and the second lifting mechanism 52 rise or fall, causing the moving frame 4 to move accordingly, so that the arc surface of the support frame 6 contacts and matches the surface of the arrow body, and is stable in its position without slippage.

[0036] To meet the requirements of a humid and salt spray corrosive launch environment, and considering that the rocket body uses liquid propellant with liquid oxygen and methane as the medium, both the first lifting mechanism 51 and the second lifting mechanism 52 adopt a technical solution combining a worm gear screw and a hydraulic motor, while taking safety into consideration.

[0037] The first lifting mechanism 51 and the second lifting mechanism 52 are both composed of main components such as housing, worm gear, worm, lead screw and lifting nut. They have the advantages of compact structure, small size, light weight, wide range of power sources, no noise, convenient installation, flexible use, multiple functions, multiple matching forms, high reliability and long service life. In addition, the lifting height can be customized according to the usage requirements and can reliably self-lock at any position within the effective stroke range. A cycloidal hydraulic motor is a power device that converts hydraulic energy into mechanical energy. Its core structure consists of a stator, rotor, distributor plate, and output shaft. It has advantages such as small size, light weight, stepless speed regulation, and low rotational inertia. The displacement can be selected according to application requirements to meet speed and torque output demands.

[0038] like Figure 1 , Figure 3 As shown, in an optional embodiment of the present invention, the pusher 8 includes: Support base 81; The telescopic rod 82 is fixedly connected to the support base 81, and the other end of the telescopic rod 82 is fixedly connected to the adapter frame 2.

[0039] In this embodiment, as Figure 1 , Figure 3 As shown, the pusher 8 includes a support base 81 and a telescopic rod 82. One end of the telescopic rod 82 is fixedly connected to the support base 81, and the other end is fixedly connected to the adapter frame 2. The pusher 8 can push the adapter frame 2 to slide on the guide rail 111 to adjust the position of the adapter frame 2.

[0040] like Figure 8 , Figure 9 As shown, in an optional embodiment of the present invention, both the first support frame 61 and the second support frame 62 include: The fourth connecting plate 611 is fixedly connected to the motion frame 4; Support plate 612 is fixedly connected to the connecting plate 611; An arc-shaped plate 613 is fixedly connected to the support plate 612, and the arc-shaped plate 613 provides support for the rocket.

[0041] In this embodiment, as Figure 8 , Figure 9 As shown, the support frame 6 is designed with an arc-shaped plate 613, a support plate 612, and a fourth connecting plate 611, and is manufactured using an assembly and welding process. Preferably, the diameter of the support surface of the arc-shaped plate 613 is φ3840mm. The support plate 612 connects the arc-shaped plate 613 and the fourth connecting plate 611, and is evenly distributed in multiple locations to ensure uniform stress on the frame and good load-bearing capacity. The fourth connecting plate 611 is a standard flat steel plate with bolt holes, and it is in surface contact with the moving frame 4 for bolt connection, ensuring reliable and stable connection. Preferably, the surface of the arc-shaped plate 613 is bonded with felt, and the felt thickness is 20mm. After bonding the 20mm thick felt to the arc-shaped plate 613, the diameter of the support surface of the arc-shaped plate 613 is φ3800mm, which matches the diameter of the arrow body φ3800mm, providing soft protection for the rigid contact of the arrow body.

[0042] like Figure 11 As shown, in an optional embodiment of the present invention, both the first translation mechanism 11 and the second translation mechanism 12 are provided with adjusting pads 7 at their bottoms, and the adjusting pads 7 include: 71; a base plate with an elongated hole; Positioning block 72 is fixedly connected to the base plate 71; Adjustment shims 73 are detachably connected to the base plate 71.

[0043] In this embodiment, as Figure 11As shown, the adjusting shim 7 is installed between the bottom of the first translation mechanism 11 and the second translation mechanism 12 and the erecting frame steel structure. It consists of a base shim 71 and an adjusting shim 73. The base shim 71 is supported by a standard steel plate with a thickness of 50mm. The adjusting shim 7 has an elongated hole, and its position can be adjusted by adjusting the gap between the bolt and the elongated hole, thereby ensuring that the erecting frame support is installed in the correct position. Preferably, the adjusting shim has a length of 1520mm, a width of 400mm, and a thickness of 80mm.

[0044] In an optional embodiment of the present invention, the adjusting shim 73 is a U-shaped sheet of preset thickness.

[0045] In this embodiment, the adjusting shim 73 is made of U-shaped sheets of different thicknesses, which can adapt to the attitude changes of the erector support caused by manufacturing errors, assembly deviations, arrow body tilting, and other factors. Compared with the existing fixed erector support (which does not have the ability to adjust the degree of freedom), the solution of the present invention has the ability to adjust the degree of freedom in both the radial and lateral directions, which can adapt to the radial and axial deviations of the rocket body, thus facilitating the assembly of the rocket. Through the design of the rectangular steel tube support frame and the guide rail of the translation mechanism inside the motion frame, the structural rigidity and load capacity are improved, and the adjustment shim can compensate for manufacturing or assembly errors through U-shaped shims and elongated holes, which greatly improves the assembly flexibility.

[0046] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
