Description

Technical Field

[0001] The present application relates to the field of aerospace technology, and in particular to an adaptive support device. Background Art

[0002] The launch vehicle power system test is an important test to verify the compatibility of the pressurization delivery system with the rocket engine. During the test, cryogenic propellants such as liquid oxygen, liquid hydrogen, and liquid methane need to be added to the rocket tank through a filling pipe. During the filling process, the filling pipe needs to remain connected to the rocket body at all times. Specifically, the filling pipe includes a hard pipe and a soft pipe. One end of the soft pipe is connected to the rocket body and the other end is connected to the filling liquid through a hard pipe. When cryogenic liquid flows through the filling pipe, the hose will shrink and deform due to the drop in temperature.

[0003] At present, a pipe support is often used to adaptively adjust the deformation of the above-mentioned hose to avoid the leakage of propellant at the arrow-ground interface; specifically, the pipe support used is provided with a guide rail and has the ability to move in a certain direction. However, the pipe support only realizes the adaptation in a single direction on the horizontal plane, and cannot move freely in the horizontal plane in the front, back, left, right and left directions, let alone up and down directions, that is, it cannot adapt to adaptive adjustment in more directions, so the propellant leakage still occurs.

[0004] In addition, there is also a commonly used spring bracket that can achieve vertical movement. However, during the movement, the spring will deform, which will generate force on the pipeline and interface. Using a counterweight to balance gravity will not generate additional force during the movement, which is better than a spring bracket.

[0059] The features of the examples described herein may be combined in various ways that will be apparent after understanding the disclosure of the present application. In addition, although the examples described herein have various configurations, other configurations are possible as will be apparent after understanding the disclosure of the present application.

[0060] At present, pipe supports are often used to adaptively adjust the deformation of the above-mentioned hose to avoid propellant leakage at the arrow-ground interface; however, the existing pipe supports only achieve adaptation in a single direction (planar direction or vertical direction), so propellant leakage still occurs in some cases; based on this, the present application provides an adaptive support device, which can not only achieve adaptation in the planar direction but also in the vertical direction, that is, the device can be adjusted with full freedom in the planar direction and the vertical direction. Figure 1-Figure 9 An adaptive support device provided by the present application is described in detail.

[0061] Combination Figure 1 , Figure 2 as well as Figure 3As shown, the adaptive support device is used to support the filling pipeline; the adaptive support device includes a base 1, a plane direction adjustment component and a vertical direction adjustment component 3.

[0062] Specifically, the plane direction adjustment component includes a fixing portion 4 , a rolling portion 5 and a buckling portion 6 ; the vertical direction adjustment component 3 includes a guide adjustment portion 7 , a counterweight adjustment portion 8 and a fixed pulley adjustment portion 9 .

[0063] Furthermore, the two ends of the fixing portion 4 along the first direction 10 are respectively arranged on the base 1 through the guide adjustment portion 7; wherein, according to Figure 1 Taking the direction of placement in the middle as an example, the first direction 10 refers to the front-to-back direction, that is, the two ends of the fixing part 4 in front and behind are respectively supported on the base 1 through the guide adjustment part 7. Among them, the base 1 is a plate-like structure, and its shape can be square, rectangular, etc.

[0064] Furthermore, the rolling portion 5 is disposed between the fixing portion 4 and the buckling portion 6, and the buckling portion 6 supports the filling pipeline through the supporting member 11. The size of the buckling portion 6 is larger than that of the fixing portion 4, that is, the buckling portion 6 can buckle and wrap the fixing portion 4. The height of the rolling portion 5 is larger than that of the fixing portion 4;

[0065] In actual application, when the filling pipeline shrinks and deforms due to the introduction of cryogenic propellant, the support member 11 can move along the plane direction on the rolling portion 5 through the buckling portion 6, so that the support member 11 adapts to the deformation of the filling pipeline; specifically, in actual use, the filling pipeline is fixed on the support member 11, so when the filling pipeline shrinks, the filling pipeline will apply a traction force to the support member 11, that is, the filling pipeline will drive the support member 11 to make a slight displacement in the plane direction. If the support member 11 is fixed to the base 1, that is, if the support member 11 is not If the filling pipeline moves, a gap will be generated at the interface between the filling pipeline and the arrow body, and the propellant will leak out from this gap. The present application sets the support member 11 on the buckling member, and the end of the buckling member away from the support member 11 is rollingly connected to the rolling part 5. Then, when the filling pipeline drives the support member 11 to make a slight displacement in the planar direction, the buckling part 6 can slide on the rolling part 5 along the planar direction and move left and right and front and back on the horizontal plane, so it will adapt to the displacement of the support member 11, thereby ensuring that the arrow-ground interface is sealed and no gap is generated, thereby ensuring that the propellant will not leak out.

[0066] It is worth noting that in the present application, the size of the buckling portion 6 is set to be larger than that of the fixing portion 4, that is, a gap is formed between the buckling portion 6 and the fixing portion 4, and this gap is just used for the buckling portion 6 to move on the fixing portion 4, providing the possibility for the horizontal movement of the supporting member 11. In addition, the height of the rolling portion 5 is greater than the height of the fixing portion 4, that is, the buckling portion 6 is in direct contact with the rolling portion 5, and can roll relative to the rolling portion 5.

[0067] Specifically, combined Figure 2 As shown, the fixed pulley adjustment part 9 is arranged on the base 1 through the supporting member 12, and is respectively located on both sides of the plane direction adjustment component along the second direction 13; Figure 1 Taking the placement angle in as an example, the second direction 13 here refers to the left-right direction, that is, the vertical direction adjustment components 3 are respectively arranged on the left and right sides of the plane direction adjustment component; preferably, the vertical direction adjustment components 3 on the left and right sides of the plane direction adjustment component are symmetrically arranged about the midline of the plane direction adjustment component. In addition, the fixed pulley adjustment part 9 is supported by the supporting member 12 to a certain height.

[0068] Furthermore, the fixing portion 4 has first lugs 14 extending from both ends along the second direction 13, i.e., the left and right sides of the fixing portion 4 have first lugs 14 extending therefrom respectively; in addition, the shape and size of the first lugs 14 are not specifically limited, and the shapes may be square, semicircular, or rectangular.

[0069] Furthermore, the fixed pulley adjusting part 9 is respectively connected to the counterweight adjusting part 8 and the first lug 14 through a connecting rope; according to the fixed pulley 30 theorem of the fixed pulley adjusting part 9, it can be known that the weight of the counterweight adjusting part 8 is equal to the total weight of the plane direction adjustment component, the supporting member 11 and the filling pipeline.

[0070] During the test run, the filling pipeline is still connected to the arrow-ground interface. However, vibrations may occur during the test run, and the vibrations may cause the filling pipeline to move up and down in the vertical direction. When the filling pipeline moves downward, the filling pipeline will apply a downward force to the plane direction adjustment component. If the plane direction adjustment component is fixed on the base 1, the plane direction adjustment component will not move due to the downward force applied. At this time, a gap will be generated at the arrow-ground interface between the filling pipeline and the arrow body, and the propellant will leak out from this gap. In the present application, the fixing portion 4 is arranged on the base 1 through the guide adjustment portion 7. When the filling pipeline applies a downward force to the plane direction adjustment component, the fixing portion 4 will move in the vertical direction on the guide adjustment portion 7. In other words, the plane direction adjustment component at this time can adapt to the movement of the filling pipeline. Due to the equal and balanced weight, the filling main pipe always maintains a balanced state, does not generate a force on the arrow-ground interface, does not damage the arrow-ground interface, and ensures sealing. In addition, due to the good sealing, no gap will be generated, which also ensures that the propellant will not leak out.

[0071] It is worth noting that the vertical direction adjustment component 3 in the present application is not only applicable during the test run, but can also adapt to the change in the weight of the arrow body during filling.

[0072] In summary, firstly, the support member in the present application can move in the plane direction on the rolling part through the buckling part, that is, the buckling part can slide in the plane direction on the rolling part, that is, it can move left and right, front and back on the horizontal plane, so it can adapt to the displacement of the support member on the plane; secondly, the fixing part is set on the base through the guide adjustment part, when the filling pipeline applies a downward force to the plane direction adjustment component, the fixing part will move in the vertical direction on the guide adjustment part, that is, the vertical direction adjustment component at this time can adapt to the vertical direction movement of the filling pipeline. It is worth mentioning that: the present application cleverly embeds the vertical direction adjustment component in the plane direction adjustment component, so that the present application can achieve both the plane direction adaptation and the vertical direction adaptation, so that it can better cooperate with the deformation and movement of the filling pipeline, will not generate force on the arrow-ground interface, will not damage the arrow-ground interface, and ensure the sealing. In addition, due to the good sealing, that is, no gaps will be generated, which also ensures that the propellant will not leak out.

[0073] In this embodiment, further, the fixing portion 4 is a bottom box 15 , the buckling portion 6 is a top box 16 , and the rolling portion 5 is a ball 17 .

[0074] Specifically, combined Figure 7 As shown, the bottom box 15 is a groove structure, and has a receiving space 18 inside. The ball 17 is arranged in the receiving space 18, and the height of the receiving space 18 is smaller than the diameter of the ball 17. Further, the shape of the bottom box 15 is not specifically limited. Figure 7 The groove structure shown in the figure is a cubic groove structure, but the application is not limited thereto, and other groove structures may also be used, such as a rectangular groove structure; however, it is worth noting that no matter what kind of groove structure is used, the diameter of the ball 17 must be greater than the height of the groove structure. Furthermore, the number and size of the ball 17 are not specifically limited, such as Fig. 9 In FIG. 1 , a similar shape of four balls 17 is shown. Figure 8 The bottom box 15 is a cubic groove structure, so the balls 17 are four balls 17 of equal diameter, ensuring that the four balls 17 are exposed from the top of the bottom box 15 and are on the same plane, so that the top box 16 can be level. If the bottom box 15 is an irregular shape, it is possible to consider using balls 17 of different diameters to ensure that the balls 17 are exposed from the top of the bottom box 15 and are on the same plane.

[0075] Specifically, combined Figure 5 and Figure 6 As shown, the top box 16 has a buckling space 19, and the top box 16 is buckled between the ball 17 and the bottom box 15, and the size of the top box 16 is larger than that of the bottom box 15, so that the top box 16 can move along the plane direction on the bottom box 15 under the action of the ball 17.

[0076] Furthermore, due to Figure 8 The bottom box 15 is a cubic groove structure, then preferably, the top box 16 is also a cubic groove structure, ensuring that the length, width and height of the top box 16 are greater than those of the bottom box 15, so that there is a gap between the top box 16 and the bottom box 15 for the top box 16 to move horizontally.

[0077] In this embodiment, further, the side wall opposite to the top box 16 extends toward the bottom box 15 with a second lug 20; Figure 1 As shown, the side wall of the top box 16 along the first direction 10 extends toward the bottom box 15 with a second lug 20 , and in addition, two second lugs 20 are provided on each side wall.

[0078] Specifically, combined Figure 3 and Figure 4 As shown, the second lug 20 protrudes from the bottom wall of the bottom box 15 ; the second lugs 20 on the opposite side walls and opposite to each other are connected by an anti-slip rod 21 , and the anti-slip rod 21 is located below the bottom box 15 .

[0079] During the process of filling and testing the arrow body, the filling pipeline may drive the support member 11 and the top box 16 to move upward. In order to prevent the top box 16 from rushing out and even more so from tipping over, the present application cleverly adopts an anti-tilt rod 21 to connect the second lugs 20 on the opposite side walls, and utilizes the anti-tilt rod 21 to prevent the top box 16 from rushing out and tipping over.

[0080] In addition, there is a small gap between the anti-falling rod 21 and the bottom box 15, which does not affect the buckling of the top box 16 on the bottom box 15 and prevents the top box 16 from falling.

[0081] In this embodiment, further, combined with Figure 1 As shown, the support member 11 includes a push rod 22 and a pipe support 23; the pipe support 23 is arranged on the side of the top box 16 away from the ball 17 through the push rod 22; the pipe support 23 has a limiting portion, which is used to fix the filling pipeline.

[0082] Specifically, the limiting portion refers to a semicircular groove formed on the pipe support 23, the diameter of the semicircular groove is the same as the diameter of the filling pipeline, so that the semicircular groove is compatible with the filling pipeline, that is, the filling pipeline is clamped in (limited in) the semicircular groove; in addition, in actual use, the filling pipeline is locked in the semicircular groove by using a semicircular bolt (the semicircular bolt is connected to the semicircular groove to form a limiting channel compatible with the filling pipeline).

[0083] Preferably, the top rod 22 is a threaded rod, one end of which is threadedly connected to the top box 16 , and the other end of which is threadedly connected to the pipe support 23 .

[0084] In this embodiment, further, combined with Figure 1 As shown, the guide adjustment portion 7 includes a screw rod 24 and a nut 25 ; and third lugs 26 are extended along both ends of the fixing portion 4 along the second direction 13 .

[0085] Specifically, the screw rod 24 is provided with a thread, one end of the screw rod 24 is fixed to the base 1 and the other end passes through the third lug 26; nuts 25 threadedly connected to the screw rod 24 are respectively provided on both sides of the third lug 26; Figure 1 As shown, nuts 25 are threadedly connected to the upper and lower sides of the third lug 26 .

[0086] Specifically, there is a preset distance between the nuts 25 on both sides of the third lug 26, and when the filling pipeline moves in the vertical direction, the bottom box 15 can move within the preset distance. Further, when the filling pipeline drives the bottom box 15 to move downward through the support member 11, the top box 16, and the ball 17, the bottom box 15 can adapt to the movement of the filling pipeline and can move downward on the screw 24, that is, the filling pipeline and the barrel of the bottom box 15 are guaranteed to move, and the bottom box 15 will not restrict the movement of the filling pipeline.

[0087] It is worth noting that: when the adaptive support device is initially installed, the height of the adjusting nut 25 can also change the initial height of the bottom box 15 to adapt to the height of the main pipeline in different occasions.

[0088] In this embodiment, further, combined with Figure 1As shown, the counterweight adjustment part 8 includes a counterweight block 27 , a bare rod 28 and a limiting member 29 .

[0089] Specifically, one end of the polished rod 28 is disposed on the base 1 and the other end extends vertically upward and passes through the counterweight 27 ; the limiting member 29 is disposed at one end of the polished rod 28 away from the base 1 .

[0090] When the filling pipeline moves in a vertical downward direction, the fixed pulley adjustment part 9 can drive the counterweight block 27 to move in a vertical upward direction on the bare rod 28; the limit member 29 is used to limit the stroke of the counterweight block 27 to prevent the counterweight block 27 from detaching from the bare rod 28.

[0091] Furthermore, there are multiple polished rods 28; the multiple polished rods 28 are arranged at equal intervals along the length direction of the counterweight block 27. Figure 1 As shown, there are two polished rods 28.

[0092] Furthermore, the limiting member 29 is a limiting nut 25 , and the limiting nut 25 is threadedly connected to the polished rod 28 .

[0093] In this embodiment, combined with Figure 1 As shown, the fixed pulley adjusting portion 9 includes a fixed pulley 30; the fixed pulley 30 is respectively connected to the counterweight 27 and the first lug 14 through connecting ropes.
