Description

Technical Field

[0001] This utility model belongs to the technical field of cable adapter panels, and relates to a rocket-to-ground cable adapter panel for a launch vehicle ground measurement and control system. Background Technology

[0002] The launch vehicle ground control and measurement system is a key system for rocket test launches. The cable between the launch vehicle and the ground (referred to as the launch vehicle-to-ground cable) used by the launch vehicle ground control and measurement system is the signal transmission path for launch vehicle test launches. In the design of various launch vehicle models, the launch vehicle-to-ground cable is divided into hoistway cable and platform cable, which are connected by a conversion part. Among them, the hoistway cable is located inside the launch tower shaft and its status is not easily changed. The testing of multiple rocket models can be carried out by converting the platform cable.

[0003] The existing rocket-to-ground cable transition section has a variety of connector models due to its role in various rocket missions; moreover, the rocket-to-ground cables are scattered haphazardly in various test rooms on the tower without being classified or effectively secured.

[0004] In practical use, the haphazard distribution of arrow and ground cables easily leads to connection errors, causing delays in testing and resulting in low efficiency during condition preparation. Furthermore, the lack of unified management and securing devices for these cables causes wear and damage, affecting the stability and reliability of signal transmission. The chaotic distribution of arrow and ground cables in the testing area also hinders connector protection, resulting in foreign objects inside some connectors, which in turn affects test preparation.

[0005] In addition, the existing design of rocket-to-ground cables is poorly adaptable to various rocket models, making it difficult to meet the rapid switching requirements of different cable types, which restricts the flexibility and efficiency of the launch vehicle ground measurement and control system.

[0006] The aforementioned problems seriously affect the efficiency and safety of launch vehicle testing, impact the reliability of the launch vehicle ground control and measurement system, and hinder its full life-cycle maintenance and use. Therefore, there is an urgent need for a rocket-to-ground cable adapter panel solution that is structurally sound, easy to operate, and highly adaptable. Utility Model Content

[0007] To address the challenge of improving the stability and reliability of rocket-to-ground cables, this invention proposes a rocket-to-ground cable adapter panel for a launch vehicle ground control and measurement system. The base plate enhances the versatility and flexibility of the adapter panel, enabling compatibility with different connector specifications and reducing maintenance costs and time. By using a front and rear panel with different hole positions, the overall structural strength of the adapter panel is improved, preventing deformation during long-term use and ensuring the stability of the rocket-to-ground cable connection. Support components are added to the front and rear of the adapter panel after the rocket-to-ground cable is connected to distribute the deformation caused by the weight of the rocket-to-ground cable, preventing excessive bending at the connection point and improving reliability. A door component provides access for testing personnel to enter and exit the adapter panel, facilitating maintenance and status checks of the rocket-to-ground cable behind the panel, thereby further enhancing the stability and reliability of the rocket-to-ground cable.

[0008] The objective of this utility model is specifically achieved through the following technical solution:

[0009] This utility model discloses a rocket-to-ground cable transfer panel for a launch vehicle ground measurement and control system. The rocket-to-ground cable transfer panel is vertically installed in the test room of the launch vehicle ground measurement and control system, dividing the test room into a platform cable operation area and a hoistway cable laying area. The rocket-to-ground cable transfer panel consists of a base plate and a door assembly installed on one side of the base plate. The platform cable operation area and the hoistway cable laying area are accessed and exited through the door assembly.

[0010] The base plate includes a front panel and a rear panel. The front panel has a first through hole, the shape of which corresponds to the edge shape of the corresponding number of connector fixing plates required by the task. The rear panel has a mounting frame for fixing the edge of the connector fixing plates. The interior of the mounting frame is a second through hole, the area of ​​which is smaller than that of the first through hole. When each mounting frame is exposed at equal intervals in the first through hole, sealant is applied to splice the front panel and the rear panel and fix them with bolts.

[0011] The connector fixing plate passes through the first through hole and is fixed to the mounting frame, so that the two ends of the connector fixed on the connector fixing plate are respectively located in the platform cable operation area and the well cable laying area;

[0012] Two support components form a set. The two ends of the two support components are respectively placed horizontally at both ends of the first through hole and symmetrically fixed to the front and rear panels of the base plate, for supporting the arrow ground cable connected to both ends of the connector.

[0013] Furthermore, according to the task requirements, multiple base plates are extended by splicing them vertically and / or horizontally. After aligning the splicing surfaces of the multiple base plates, sealant is applied and they are fixed with bolts.

[0014] Furthermore, the second through hole includes a plurality of spaced sub-through holes, which are connected by a sub-frame, the sub-frame being used to fix it to the connector fixing plate.

[0015] Furthermore, the first through hole, the second through hole, and the sub-through hole are rectangular.

[0016] Furthermore, the connector fixing plate is formed by sequentially splicing an upper fixing plate, a middle fixing plate, and a lower fixing plate from top to bottom, and has an internal structure with two rows of spaced through holes for fixing the connector.

[0017] Furthermore, both the lower splicing edge of the upper fixing plate and the upper splicing edge of the lower fixing plate have half through holes arranged at equal intervals, corresponding to the number of connectors required and the installation size of the connectors.

[0018] The upper and lower splicing edges of the middle fixing plate each have a half-hole that matches the half-hole of the upper fixing plate and the lower fixing plate.

[0019] Furthermore, the support assembly includes a U-shaped support rod and angle steel;

[0020] The two U-shaped support rods are identical in shape and arranged vertically. The length of the U-shaped support rods is not less than the horizontal width of the connector fixing plate, and the spacing between them is not less than half the height of the connector fixing plate.

[0021] The angle steel has an L-shaped cross-section and extends axially. The two ends of the two U-shaped support rods are respectively welded to two angle steels with openings facing outward and symmetrically distributed.

[0022] Two angle steels are located at the edges of the connector fixing plate width, with the upper U-shaped support rod of the angle steel located at the lower end of the through hole on the connector fixing plate, and the lower U-shaped support rod located at the lower end of the through hole on the connector fixing plate, and then fixed to the base plate.

[0023] Furthermore, the arrow-ground cables are laid on two U-shaped support poles and secured with ropes according to their classification.

[0024] Furthermore, it also includes an adapter box base installed in the upper part of the front panel for placing the cable adapter box;

[0025] The base of the adapter box is composed of side angle steel, bottom angle steel and base plate;

[0026] Two symmetrically distributed angle steels with inward openings serve as side angle steels. The spacing between the symmetrical angle steels in the side angle steels is set based on the size of the junction box and then fixed to the base plate.

[0027] Two symmetrically distributed angle steels with openings facing upwards serve as bottom angle steels. The bottom plate is placed on the bottom angle steels and welded. After removing burrs, it is welded to the side angle steels at a right angle.

[0028] Furthermore, the door assembly consists of a door, a door frame, and hinges;

[0029] The door is connected and fixed to one side of the door frame by hinges using Phillips head countersunk self-tapping screws.

[0030] The beneficial effects of this utility model are:

[0031] 1. The rocket-to-ground cable adapter panel disclosed in this utility model is customized according to the wall size of the test room and is vertically installed in the test room of the launch vehicle ground measurement and control system. It divides the test room into a platform cable operation area and a well cable laying area, enabling zoned management of the test room, improving the space utilization of the test room, and improving the storage environment of the rocket-to-ground cables that are scattered. Various types of connectors, adapter boxes, etc. can be fixed on this panel, which has high flexibility and operability and improves the maintenance capability of the ground measurement and control system.

[0032] 2. The cable transfer panel consists of a base plate and a door assembly installed on one side of the base plate. The platform cable operation area and the shaft cable laying area are accessed through the door assembly, which facilitates the transportation of parts. At the same time, while the cable transfer panel separates the test room, it provides a passage for testers to enter and exit the space behind the transfer panel, so that testers can easily check the status behind the transfer panel.

[0033] 3. The base plate includes a front panel and a rear panel. The front panel has a first through hole, the shape of which corresponds to the edge shape of the corresponding number of connector fixing plates required by the task. The rear panel has a mounting frame for fixing the edge of the connector fixing plate. The inside of the mounting frame is a second through hole, the area of ​​which is smaller than that of the first through hole. When each mounting frame is exposed at equal intervals in the first through hole, sealant is applied to splice the front panel and the rear panel and fix them with bolts. This improves the stability and replacement flexibility of the base plate.

[0034] 4. The connector fixing plate is designed in groups according to the actual needs of the rocket-to-ground cables, ensuring that the platform cables will not cross during use and facilitating cable management. The connector fixing plate passes through the first through hole and is fixed to the mounting frame, so that the two ends of the connector fixed on the connector fixing plate are respectively located in the platform cable operation area and the hoistway cable laying area. The conversion parts of the rocket-to-ground cables are all designed to be fixed on the connector fixing plate, improving the versatility of the rocket-to-ground cable conversion panel for testing multiple rocket models. If it is found that the cable fixed by the A group plate 21 needs to be replaced during testing, only the A group plate 21 needs to be removed, without disassembling the entire rocket-to-ground cable conversion panel, making the rocket-to-ground cable conversion panel flexible for maintenance.

[0035] 5. Since the well cable has been laid at this stage, and the square seat end of the connector needs to be fixed on the front of the connector fixing plate 2, taking the A group plate 21 as an example, it is designed with a three-section detachable structure (upper, middle, and lower) and adopts a double-layer semi-circular opening clamp method, which can fix the electrical connector without removing the square seat end.

[0036] 6. Two support components form a group. The two ends of the two support components are respectively placed horizontally at both ends of the first through hole and symmetrically fixed to the front and rear panels of the base plate. They are used to support the arrow ground cables connected to both ends of the connector. The symmetrical design of the support components ensures that the connector is subjected to uniform force before and after the cable is connected, which can avoid large bending of the cable and has good vibration resistance, which is conducive to improving the cable life and the reliability of the connector connection.

[0037] 7. The base of the adapter box provides support for the adapter box. Side angle steel on both sides restricts the adapter box to the left and right, and bottom angle steel at the bottom of the adapter box restricts the adapter box to the front and back. Finally, the base plate ensures the stability of the adapter box during test launch.

[0038] 8. During the production of the rocket-to-ground cable adapter panel, the connector codes and drawing numbers are printed onto the panel according to mission requirements. This avoids the need for testers to search for each cable individually, allowing for quick connection based on different rocket conditions. This improves the efficiency of preparation and inspection, significantly reducing equipment recovery time. Before using the cable adapter panel, recovery and condition checks in the test room required a full day and a morning (3.5 hours in the morning and 2.5 hours in the afternoon, totaling 9.5 hours). After using it, the time is reduced to a morning (3.5 hours), improving the post-launch recovery capability of the ground-based launch control system.

[0039] 9. The front panel and the rear panel together form a double-layer base plate. The double-layer plate is thicker and more stable than the single-layer plate, making it more stable in complex environments such as towers.

[0040] 10. The opening method of the rear panel can ensure that the connector fixing plate is embedded in the opening of the front panel, and play a fixing role around the connector fixing plate, so as to achieve the purpose of the entire front panel being flat.

[0041] 11. The base board uses a front panel and a rear panel stacked together. Since the connector mounting plate is only fixed to the rear panel, when a part of the entire panel needs maintenance, only the rear panel needs to be replaced, which improves the maintainability of the cable adapter panel.

[0053] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0054] like Figure 1As shown, this embodiment of the utility model provides a rocket-to-ground cable transfer panel for a launch vehicle ground measurement and control system. The rocket-to-ground cable transfer panel is vertically installed in the test chamber of the launch vehicle ground measurement and control system, dividing the test chamber into a platform cable operation area and a hoistway cable laying area. The rocket-to-ground cable transfer panel consists of a base plate 1 and a door assembly 5 installed on one side of the base plate 1, and is fixed by M20 bolts with a bolt spacing of 300mm. The platform cable operation area and the hoistway cable laying area are accessed and exited through the door assembly 5.

[0055] The base plate 1 includes a front panel and a rear panel. The front panel has a first through hole, the shape of which corresponds to the edge shape of the corresponding number of connector fixing plates 2 required by the task. The rear panel has a mounting frame for fixing the edge of the connector fixing plates 2. The inside of the mounting frame is a second through hole, the area of ​​which is smaller than that of the first through hole. When each mounting frame is exposed at equal intervals in the first through hole, sealant is applied to splice the front panel and the rear panel and fix them with bolts.

[0056] The connector fixing plate 2 passes through the first through hole and is fixed to the mounting frame, so that the two ends of the connector fixed on the connector fixing plate 2 are respectively located in the platform cable operation area and the well cable laying area;

[0057] Two support components 3 form a group. The two ends of each support component 3 are horizontally positioned at both ends of the first through hole and symmetrically fixed to the front and rear panels of the base plate 1, respectively, to support the grounding cables connected to both ends of the connector, such as... Figure 2 As shown.

[0058] According to the task requirements, multiple base plates 1 are extended by splicing them vertically and / or horizontally. After the splicing surfaces of multiple base plates 1 are aligned, sealant is applied and they are fixed with bolts.

[0059] like Figure 3 and Figure 4 As shown, according to the task requirements, the two base plates are spliced ​​together to extend into a base plate, including a front upper plate 11, a rear upper plate 12, a front lower plate 13, and a rear lower plate 14. The splicing surfaces of the front upper plate 11 and the rear upper plate 12, the front lower plate 13 and the rear lower plate 14 are coated with sealant, and spliced ​​together front and back with 5 M20 bolts with a bolt spacing of 450mm. The rear plates are then aligned vertically and spliced ​​together vertically with 4 M20 bolts with a bolt spacing of 450mm to form the base plate 1.

[0060] like Figure 3 and Figure 4 As shown, the second through hole includes a plurality of spaced sub-through holes, which are connected by a sub-frame, and the sub-frame is used to fix it to the connector fixing plate 2.

[0061] Preferably, the first through hole, the second through hole, and the sub-through hole are rectangular.

[0062] like Figure 5 and Figure 6 As shown, the connector fixing plate 2 is formed by sequentially splicing the upper fixing plate 211, the middle fixing plate 212 and the lower fixing plate 213 from top to bottom. The interior has a structure of two rows of spaced through holes to fix the connector.

[0063] The lower splicing edge of the upper fixing plate and the upper splicing edge of the lower fixing plate both have half through holes arranged at equal intervals, corresponding to the number of connectors required and the installation size of the connectors.

[0064] The upper and lower splicing edges of the middle fixing plate each have a half-hole that matches the half-hole of the upper fixing plate and the lower fixing plate.

[0065] Optionally, based on the branching of the arrow-ground cable, the cables on a group of connector mounting plates 2 collectively constitute a branch of a platform cable, ensuring that there is no interference between the branch cables when connecting the platform cables, such as... Figure 6 As shown, according to the task requirements, the connector fixing plate 2 is divided into five groups, including group A plate 21, group B plate 22, group C plate 23, group D plate 24 and group E plate 25.

[0066] Group A board 21 includes: A upper board 211, A middle board 212 and A lower board 213;

[0067] Group B board 22 includes: upper B board 221, middle B board 222 and lower B board 223;

[0068] Group C board 23 includes: C upper board 231, C middle board 232 and C lower board 233;

[0069] Group D board 24 includes: D board 241, D board middle 242 and D board bottom 243;

[0070] E-group board 25 includes: E-top 251, E-center 252, and E-bottom 253.

[0071] Taking the installation of board A 21 as an example, board A 21 consists of board A upper 211, board A middle 212, and board A lower 213. Board A upper 211, board A middle 212, and board A lower 213 have been pre-drilled according to the installation dimensions of the connectors to be fixed. Board A upper 211, board A middle 212, and board A lower 213 are all fixed to the upper rear plate 12 with four M8 bolts. The assembly steps are as follows:

[0072] First, install the lower section 213 of board A onto the left opening of the upper rear plate 12, aligning its lower edge with the base plate 1. Then, place the connector at the opening of the lower section 213 of board A. Next, fix the middle section 212 of board A onto the upper rear plate 12. Secure the lower row of connectors fixed to board A 21 using the lower section 213 and the middle section 212 of board A. Then, place the connector at the opening of the middle section 212 of board A. Finally, fix the upper section 211 of board A onto the upper rear plate 12. Secure the upper row of connectors fixed to board A 21 using the middle section 212 and the upper section 211 of board A. Through this three-section design, the fixing and installation of board A 21 and the two rows of connectors are completed.

[0073] The installation methods for group B panels 22, group C panels 23, group D panels 24, and group E panels 25 are the same as those for group A panels 21, and will not be repeated here.

[0074] like Figure 7 and Figure 8 As shown, the support assembly includes a U-shaped support rod and angle steel;

[0075] The two U-shaped support rods are identical in shape and arranged vertically. The length of the U-shaped support rods is not less than the horizontal width of the connector fixing plate 2, and the spacing between them is not less than half the height of the connector fixing plate 2.

[0076] The angle steel has an L-shaped cross-section and extends axially. The two ends of the two U-shaped support rods are respectively welded to two angle steels with openings facing outward and symmetrically distributed.

[0077] Two angle steels are located at the edges of the connector fixing plate 2, and the upper U-shaped support rod of the angle steel is located at the lower end of the through hole on the connector fixing plate, and the lower U-shaped support rod is located at the lower end of the lower through hole on the connector fixing plate and then fixed to the base plate.

[0078] The arrow-ground cables are laid on two U-shaped support poles and secured with ropes according to their classification.

[0079] like Figure 7 and Figure 8 As shown, according to the task requirements, the support component 3 is composed of A board frame 31, B board frame 32, CD board frame 33, and E board frame 34, which are installed symmetrically in pairs, front and back.

[0080] The spacing of the U-shaped support rods in the A-board frame 31, B-board frame 32, CD-board frame 33, and E-board frame 34 is determined by the opening gap of the connector fixing plate 2 and is set to 150mm. This ensures that the cable is supported while allowing the tester to connect the cable.

[0081] A-plate frame 31 is installed on both sides of A-group plate 21, with its upper edge flush with the upper edge of A-plate 212;

[0082] B-board frame 32 is installed on both sides of B-group board 22, with its upper edge flush with the upper edge of B-board 222.

[0083] CD board holder 33 is installed on both sides of C group board 23 and D group board 24, with its upper edge flush with the upper edge of C board 232 and D board 242;

[0084] E-board frame 34 is installed on both sides of E-group board 25, with its upper edge flush with the upper edge of E-board 252.

[0085] Board A frame 31, board B frame 32, board C frame 33, and board E frame 34 are all fixed to the base plate 1 with M8 bolts (bolt spacing 50mm). They are also installed symmetrically front and back to form the front and rear support components 3.

[0086] like Figure 9 As shown, it also includes an adapter box base 4 installed in the upper part of the front panel for placing the cable adapter box;

[0087] The adapter box base 4 is composed of side angle steel 41, bottom angle steel 43 and base plate 42;

[0088] Two symmetrically distributed angle steels with inward openings serve as side angle steels 41. The spacing between the symmetrical angle steels in the side angle steels is set based on the size of the junction box and then fixed to the base plate.

[0089] Two symmetrically distributed angle steels with upward openings serve as bottom angle steels 43. The bottom plate 42 is placed on the bottom angle steels 43 and welded. After removing burrs, it is welded to the side angle steels 41 at a right angle.

[0090] The design of the junction box base 4 is due to the fact that the rocket ground cable of a certain type of rocket is designed with an intermediate junction box, one end of which is connected to part of the rocket ground cable and the other end is connected to the platform cable. Since the distance of the junction cable used to connect to the rocket ground cable is limited, the junction box base 4 can be set between the A group plate 21 and the B group plate 22.

[0091] Two side angle steels 41 are fixed to the base plate 1 with M8 bolts (bolt spacing 34mm). The spacing between the side angle steels 41 is 292mm (customized according to the actual adapter box size). The two bottom angle steels 43 and the base plate 42 are welded together. After removing the burrs, they are welded to the side angle steels 41.

[0092] like Figure 10 As shown, the door assembly 5 consists of a door 51, a door frame 52, and a hinge 53;

[0093] The door 51 and one side of the door frame 52 are connected and fixed by hinges 53 using cross-head countersunk self-tapping screws (ST4.8).

[0094] Preferably, after aligning and attaching one side of the door assembly 5 with one side of the base plate 1, it is fixed with 5 M20 bolts with a bolt spacing of 300mm.

[0095] After the rocket-to-ground cable adapter panel is installed, the adapter portion of the rocket-to-ground cable is completely fixed to the adapter panel. Depending on the rocket model used in the mission, a self-test of the platform cables must be performed before each mission before they can be connected to the adapter panel.

[0096] The beneficial effects of this utility model embodiment are:

[0097] 1. The rocket-to-ground cable adapter panel disclosed in this utility model is customized according to the wall size of the test room and is vertically installed in the test room of the launch vehicle ground measurement and control system. It divides the test room into a platform cable operation area and a well cable laying area, enabling zoned management of the test room, improving the space utilization of the test room, and improving the storage environment of the rocket-to-ground cables that are scattered. Various types of connectors, adapter boxes, etc. can be fixed on this panel, which has high flexibility and operability and improves the maintenance capability of the ground measurement and control system.

[0098] 2. The cable transfer panel consists of a base plate and a door assembly installed on one side of the base plate. The platform cable operation area and the shaft cable laying area are accessed through the door assembly, which facilitates the transportation of parts. At the same time, while the cable transfer panel separates the test room, it provides a passage for testers to enter and exit the space behind the transfer panel, so that testers can easily check the status behind the transfer panel.

[0099] 3. The base plate includes a front panel and a rear panel. The front panel has a first through hole, the shape of which corresponds to the edge shape of the corresponding number of connector fixing plates required by the task. The rear panel has a mounting frame for fixing the edge of the connector fixing plate. The inside of the mounting frame is a second through hole, the area of ​​which is smaller than that of the first through hole. When each mounting frame is exposed at equal intervals in the first through hole, sealant is applied to splice the front panel and the rear panel and fix them with bolts. This improves the stability and replacement flexibility of the base plate.

[0100] 4. The connector fixing plate is designed in groups according to the actual needs of the rocket-to-ground cables, ensuring that the platform cables will not cross during use and facilitating cable management. The connector fixing plate passes through the first through hole and is fixed to the mounting frame, so that the two ends of the connector fixed on the connector fixing plate are respectively located in the platform cable operation area and the hoistway cable laying area. The conversion parts of the rocket-to-ground cables are all designed to be fixed on the connector fixing plate, improving the versatility of the rocket-to-ground cable conversion panel for testing multiple rocket models. If it is found that the cable fixed by the A group plate 21 needs to be replaced during testing, only the A group plate 21 needs to be removed, without disassembling the entire rocket-to-ground cable conversion panel, making the rocket-to-ground cable conversion panel flexible for maintenance.

[0101] 5. Since the well cable has been laid at this stage, and the square seat end of the connector needs to be fixed on the front of the connector fixing plate 2, taking the A group plate 21 as an example, it is designed with a three-section detachable structure (upper, middle, and lower) and adopts a double-layer semi-circular opening clamp method, which can fix the electrical connector without removing the square seat end.

[0102] 6. Two support components form a group. The two ends of the two support components are respectively placed horizontally at both ends of the first through hole and symmetrically fixed to the front and rear panels of the base plate. They are used to support the arrow ground cables connected to both ends of the connector. The symmetrical design of the support components ensures that the connector is subjected to uniform force before and after the cable is connected, which can avoid large bending of the cable and has good vibration resistance, which is conducive to improving the cable life and the reliability of the connector connection.

[0103] 7. The base of the adapter box provides support for the adapter box. Side angle steel on both sides restricts the adapter box to the left and right, and bottom angle steel at the bottom of the adapter box restricts the adapter box to the front and back. Finally, the base plate ensures the stability of the adapter box during test launch.

[0104] 8. During the production of the rocket-to-ground cable adapter panel, the connector codes and drawing numbers are printed onto the panel according to mission requirements. This avoids the need for testers to search for each cable individually, allowing for quick connection based on different rocket conditions. This improves the efficiency of preparation and inspection, significantly reducing equipment recovery time. Before using the cable adapter panel, recovery and condition checks in the test room required a full day and a morning (3.5 hours in the morning and 2.5 hours in the afternoon, totaling 9.5 hours). After using it, the time is reduced to a morning (3.5 hours), improving the post-launch recovery capability of the ground-based launch control system.

[0105] 9. The front panel and the rear panel together form a double-layer base plate. The double-layer plate is thicker and more stable than the single-layer plate, making it more stable in complex environments such as towers.
