Description

Technical Field

[0001] The utility model belongs to the field of rocket launching, and relates to a docking support device, in particular to a rocket docking support device and a launch platform support arm. Background Art

[0002] Before the rocket is launched, the launch platform is used to vertically support and fix the rocket to complete the vertical adjustment of the rocket body. The launch platform structure usually consists of a platform body, legs, support arms, and windbreaks. There are usually four support arms, the bottom of which is installed on the launch platform surface, and the extension is provided with longitudinal through holes for installing windbreaks. The support plate of the windbreak directly supports the rocket foot, and a device for pressing the foot is provided to fix the rocket.

[0003] Usually, an arrow foot is provided at the bottom of the tail section of the rocket body, which is vertically supported on a supporting device at the top of the support arm of the launch platform. The common bottom surface of the arrow foot is a plane, and the top surface of the supporting device is designed to be disc-shaped. A concave plane is provided in the middle of the disc to receive the bottom surface of the arrow foot. This supporting device is usually called a supporting plate. For rockets in the three vertical (vertical transfer of rockets, vertical assembly, and vertical testing) test and launch modes, a hoist is used to hoist the rocket body in a vertical state, adjust the radial and tangential positions of the rocket body, dock with the supporting plate, and place it on the supporting plate. The supporting plate does not need to adjust the radial and tangential positions. For rockets in the three horizontal (horizontal transfer of rockets, horizontal assembly, and horizontal testing) test and launch modes, an erection device is used to convert the rocket from a horizontal state to a vertical state, and it is lowered to dock with the supporting plate. Usually, the erection device is used to fine-tune the position of the rocket body to adapt to docking errors. The supporting plate does not need to adjust the radial and tangential positions.

[0004] There are also rockets where the tail section of the rocket body does not have a foot for vertically supporting the rocket body, but uses the tail end face of the rocket body to vertically support the rocket body, and the tail end face of the rocket body is provided with connection holes distributed on the circumference of the tail end face. In this case, usually when the rocket body is in a horizontal state, a support ring is used to connect with the tail end face of the rocket body. The support ring is transported together with the rocket body, erected together, and the rocket body is supported by the support ring, which is connected to the support arm of the launch platform, and the rocket body is supported vertically on the launch platform by the support ring.

[0005] At present, the foot support and tail end face support have been maturely applied. The weight of the rocket in the vertical state is borne by the tail end face, and the tail section of the rocket body needs a stronger structure, which is not conducive to reducing the weight of the rocket body structure and reduces the rocket's carrying capacity.

[0006] In order to reduce weight, a large launch vehicle has four support positions located at the waist of the tail section. The support method is to distribute the horizontal axis tangentially along the arrow wall. The middle section of the horizontal axis passes through the shaft sleeve and is fixed to the outer wall of the tail section. The usable support positions are the two cylindrical surfaces at both ends of the horizontal axis. According to the force calculation results of the support position of the rocket in the upright state, the pressure borne by the support device is 5 to 9 times the tensile force it bears.

[0007] Since the support method on the arrow is a circular axis cylinder, the launch platform support arm support method needs to use a circular hole cylinder. When the arrow body is vertically docked with the launch platform, the arrow body is lowered and the horizontal axis falls into the horizontal hole of the support. Since the contact surface is not a plane, considering the docking position deviation, the support device is required to adapt to the position deviation of the horizontal axis along the tangential and radial directions of the rocket. Considering the horizontal deviation of the horizontal axis, the support device is required to adapt to the radial rotation deviation of the horizontal axis around the rocket. Avoid the horizontal axis on the arrow from being subjected to additional force. When the rocket ignites and takes off, when the horizontal axis detaches from the support device, the support device is required to adapt to the takeoff drift and not impose restraining force on the rocket.

[0008] In summary, the prior art has the following problems: during the process of docking the rocket with the launch platform support arm, due to docking deviation, the horizontal axis of the rocket body and the support device cannot be docked. Utility Model Content

[0035] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the utility model is now described.

[0036] like Figure 1 , Figure 6 As shown, the utility model provides a rocket docking support device and a launch platform support arm.

[0037] On the one hand, if Figure 1 and Figure 5 As shown, the embodiment of the utility model provides a rocket docking support device, comprising:

[0038] An adjusting mechanism 1 capable of adjusting the pitch angle and a supporting block 2 connected to the top of the adjusting mechanism 1 ; a rotating shaft 21 is arranged at the bottom of the supporting block 2 , and a first shaft hole matching the rotating shaft 21 is arranged at the top of the adjusting mechanism 1 .

[0039] The adjustment mechanism 1 has the functions of pitch and yaw rotation. A rotating shaft 21 is provided at the lower part of the support block 2, and the rotating shaft 21 passes through the first axial hole at the top of the adjustment mechanism 1, so that the support block 2 has a rolling function. The support block 2 is used to support the horizontal axis of the rocket tail section 6. The embodiment of the utility model only involves the support device, and it is usually necessary to set a windproof pressure plate, which is used in conjunction with the support device to form a windproof device to ensure that the vertical rocket will not fall under the wind load.

[0040] Furthermore, if Figure 1 and Figure 3As shown, the adjustment mechanism 1 includes: a lower bracket 11, a cross shaft 12, and an upper bracket 13; the cross shaft 12 includes a short shaft 121 and a long shaft 122; the short shaft 121 is connected to both sides of the lower bracket 11; and the long shaft 122 is connected to both sides of the upper bracket 13.

[0041] The lower bracket 11, the cross shaft 12, and the upper bracket 13 form a Hooke's hinge mechanism to form an adjustment mechanism 1, which has pitch and yaw rotation functions.

[0042] Furthermore, if Figure 2 As shown, the lower bracket 11 includes a bottom plate 111 and lower ears 112 located on both sides of the bottom plate 111 , and two ends of the short shaft 121 are respectively connected to the two lower ears 112 .

[0043] like Figure 4 As shown, the upper bracket 13 includes a top plate 131 and upper ears 132 located on both sides of the top plate 131 , and the two ends of the long axis 122 are respectively connected to the two upper ears 132 , wherein the first shaft hole is set in the middle of the top plate 131 .

[0044] The lower bracket 11 is composed of a bottom plate 111 and a lower support ear 112. The bottom plate 111 of the lower bracket 11 is fixedly connected to the top of the support arm. There are two lower support ears 112, which are distributed on the left and right sides of the bottom plate 111. The gap between the lower support ear 112 and the top plate 131 limits the pitch rotation angle range to between 1° and 2°, avoiding collision with the arrow body due to excessive rotation angle.

[0045] The upper bracket 13 is composed of a top plate 131 and an upper support ear 132. The top plate 131 of the upper bracket 13 abuts against the bottom end of the support block 2. There are two upper support ears 132, which are distributed at both ends of the top plate 131.

[0046] The two lower ears 112 are connected to the two ends of the short axis 121, and the two upper ears 132 are connected to the two ends of the long axis 122. Figure 1 As shown, in the adjustment mechanism 1, there is a gap between the upper support ear 132 and the lower support ear 112, and there is also a gap between the lower support ear 112 and the top plate 131. Preferably, the gap between the upper support ear 132 and the lower support ear 112 is set between 1° and 2°, thereby limiting the pitch rotation angle range of the adjustment mechanism 1 to between 1° and 2°, avoiding collision with the arrow body due to excessive rotation angle, and the gap between the lower support ear 112 and the top plate 131 is set between 1° and 2°, thereby limiting the yaw rotation angle range of the adjustment mechanism 1 to between 1° and 2°, avoiding collision with the arrow body due to excessive rotation angle.

[0047] like Figure 5As shown, further, the support block 2 also includes a support base plate 22 and receiving blocks 23 arranged on both sides of the support base plate 22, and a placement groove is arranged on the upper end of the receiving block 23. The support base plate 22 abuts against the top plate 131 of the upper bracket 13, and the support block 2 can rotate relative to the upper bracket 13 around the rotating shaft 21. There are two receiving blocks 23, which are distributed on both sides of the support base plate 22. A placement groove is arranged on the upper end of the receiving block 23 for receiving the horizontal axis of the arrow body. There is a shaft sleeve in the middle of the horizontal axis, and the supporting position is two cylindrical surfaces at both ends of the horizontal axis. The recess between the two receiving blocks 23 can avoid the shaft sleeve to avoid interference between the two.

[0048] Furthermore, the support block 2 further comprises a retaining ring 211 disposed on the rotating shaft 21. Under the tensile force condition, the retaining ring 211 is used to limit the support block 2 from separating from the upper bracket 13.

[0049] Furthermore, the placement groove provided at the upper end of the receiving block 23 is a U-shaped groove, and a ball socket is provided at the lower end of the rotating shaft 21. Since the horizontal axis is a cylinder, the placement groove is provided as a U-shaped groove matching the size of the cylinder, which can facilitate the placement of the horizontal axis and make the placement of the horizontal axis more stable. The lower end of the rotating shaft 21 is provided with a ball socket to increase the pressure bearing capacity.

[0050] Furthermore, the entire bottom plate 111 is provided with a ball socket, the upper end of the intersection of the cross shaft 12 is provided with an upper ball crown 123, the upper end of the intersection of the cross shaft 12 is provided with a lower ball crown 124, the upper ball crown 123 is connected to the ball socket in the rotating shaft 21, and the lower ball crown 124 is connected to the ball socket in the lower bracket 11. The lower ball crown 124 and the upper ball crown 123 are provided at the center of the cross shaft 12, and the middle part of the bottom plate 111 of the lower bracket 11 is provided with a ball socket to accommodate the lower ball crown 124 of the cross shaft 12, which can transmit pressure, and the ball socket provided at the end of the lower end of the rotating shaft 21 is used to accommodate the upper ball crown 123 of the cross shaft 12 to increase the pressure bearing capacity. The cross shaft 12 can transmit tension or partial pressure. The ball crown structure can directly transmit the pressure of the arrow body from the support block 2 to the top of the support arm, thereby increasing the pressure bearing capacity.

[0051] Furthermore, a second axial hole is provided in the middle of the upper support ear 132, and the two ends of the long axis 122 are connected to the upper bracket 13 through the second axial hole; a third axial hole is provided in the middle of the lower support ear 112, and the two ends of the short axis 121 are connected to the lower bracket 11 through the third axial hole. The third axial hole is opened in the middle of the lower support ear 112 to install the short axis 121 of the cross axis 12, so that it has a pitch rotation function, and the second axial hole is opened in the middle of the upper support ear 132 to install the long axis 122 of the cross axis 12, so that it has a yaw rotation function.

[0052] Furthermore, the size of the placement groove matches the size of the horizontal axis of the rocket body, the retaining ring 211 is a nut, and the surface of the rotating shaft 21 has a thread matching the nut. The function of the retaining ring 211 is to limit the separation of the support block 2 from the upper bracket 13 under the tensile condition. In order to facilitate installation and disassembly, the retaining ring 211 is formed by a combination of threads and nuts, thereby achieving the purpose of limiting the separation of the support block 2 from the upper bracket 13.

[0053] like Figure 6 As shown, on the other hand, an embodiment of the utility model provides a launch pad support arm, including: a rocket docking support device 7, a vertical section 3 and an extension section 4; the upper end of the vertical section 3 is connected to one end of the extension section 4 at a preset angle, and the other end of the extension section 4 is connected to the rocket docking support device 7.

[0054] The launch pad support arm with a rocket docking support device 7 can be used to vertically support a rocket with a transverse axis support method. The rocket docking support device 7 is installed at the top of the launch pad support arm. The rocket body tail section 6 is vertically supported by four launch pad support arms of the launch pad 5. The launch pad support arm is installed on the table of the launch pad 5, wherein the lower end of the vertical section 3 of the launch pad support arm is connected to the table of the launch pad 5, and the rocket docking support device 7 is located at the extension section 4 of the support arm.

[0055] In the embodiment of the utility model, pitch, yaw and roll are used to describe the posture and motion state of the aircraft in the air. Pitch is the angle of rotation of the aircraft around the horizontal axis, yaw is the angle of rotation of the aircraft around the vertical axis, and roll is the angle of rotation of the aircraft around the longitudinal axis. In the embodiment of the utility model, the adjustment function of the adjustment mechanism 1 enables the rocket docking support device 7 to be angle-adjusted. Specifically, it can perform three rotational degrees of freedom: pitch, yaw and roll. This can solve the problem that the horizontal axis of the rocket body and the rocket docking support device 7 cannot be docked due to docking deviation during the docking process of the rocket on the launch platform support arm. The support block 2 is provided with a placement groove, especially a U-shaped groove. During the docking process between the horizontal axis of the rocket body and the support block 2, the U-shaped groove has a self-guiding function, and can adaptively adjust the position of the support block 2 within a certain range, thereby solving the problem of additional force on the rocket body. The rocket ignites and takes off. When the transverse axis is separated from the rocket docking support device 7, the rocket docking support device 7 has three rotational degrees of freedom of pitch, yaw and roll, which can adapt to the rocket take-off drift and do not impose constraints on the rocket; the structure of the lower bracket 11, the cross axis 12, and the upper bracket 13 limits the rotation angle of the adjustment mechanism 1 to between 1° and 2°, which adapts to the needs of adjusting the docking deviation and avoids the possibility of collision with the rocket body due to excessive rotation; the intersection of the cross axis 12 is provided with an upper spherical crown 123 and a lower spherical crown 124, which can withstand greater pressure; the launch platform support arm with the rocket docking support device 7 can be used to vertically support a rocket with a transverse axis support method.

[0056] The above is only an illustrative specific implementation of the utility model, and is not intended to limit the scope of the utility model. The various components of the utility model can be combined with each other under non-conflicting conditions, and any equivalent changes and modifications made by any technician in the field without departing from the concept and principle of the utility model should fall within the scope of protection of the utility model.
