Description

Technical Field

[0001] This utility model belongs to the technical field of spacecraft support equipment, and in particular relates to a horizontal parking device for a conical resource compartment. Background Technology

[0002] The resource module, also known as the propulsion module, instrument module, or service module depending on its specific functional orientation, is an important section of a spacecraft. Its exterior primarily houses the solar panels for the power system and the engines for the propulsion system, providing electricity and power for the spacecraft. Unlike previous cylindrical resource modules, the Tiangong space station's experimental module has a conical configuration. To reduce the impact of engine plumes on equipment in the resource module or other functional modules, and to improve the field of view of the external telemetry and control antennas and GNC sensors, the external equipment protrudes significantly from the conical mounting surface, resulting in a complex equipment envelope. Furthermore, the flexible solar panels span three modules—the conical structure, the solar orientation device, and the truss assembly—requiring the resource module to be tilted and its mounting surface to be horizontal during installation.

[0003] Previously, resource modules or other functional modules of spacecraft (mainly sealed modules), such as the Soyuz manned spacecraft, Shenzhou manned spacecraft, Tianzhou cargo spacecraft, Tiangong-1 target spacecraft, Tiangong-2 space laboratory, and the new generation manned spacecraft test vehicle, were mostly cylindrical structures with simple external enclosures and small dimensions. Most resource modules only need to be assembled in a vertical state (the cylindrical surface of the cylindrical structure is approximately perpendicular to the horizontal plane), and there is rarely a need for assembly in a horizontal state (the end faces of the cylindrical structure are approximately perpendicular to the horizontal plane). The cylindrical sealed modules are assembled by supporting both ends of the cylindrical structure with a horizontal parking trolley. The two support end faces of the horizontal parking trolley are at the same height and parallel, which cannot meet the requirements of the conical structure of the Tiangong space station's experimental module for external enclosure and for achieving a horizontal state for the installation surface of the equipment on the module. The existing ground equipment for achieving the tilting state of spacecraft is the two-dimensional turntable, but its development cycle is long, the development and maintenance costs are high, and it also has shortcomings in terms of generalization. This is not conducive to the ground equipment management and cost control of units that manufacture spacecraft of various configurations and sizes and have a limited number of spacecraft missions.

[0004] How to achieve a horizontal equipment mounting surface on the conical resource compartment at a relatively low cost and adapt to the complex envelope state outside the conical resource compartment is an urgent problem to be solved in the assembly of the conical resource compartment. Utility Model Content

[0005] The purpose of this invention is to provide a conical structure resource module horizontal parking device to meet the horizontal parking requirements of the Tiangong space station's experimental module.

[0006] To solve the above problems, the technical solution of this utility model is as follows:

[0007] A horizontal parking device for a conical resource compartment includes:

[0008] A parking rack, wherein the parking rack is a flat truss structure, and support platform a and support platform b are respectively provided at both ends of the parking rack;

[0009] A two-dimensional adjustment mechanism is installed on support platform b;

[0010] A limiting frame is mounted on the two-dimensional adjustment mechanism and moves with the two-dimensional adjustment mechanism in the plane; the limiting frame is provided with a V-groove.

[0011] Process ring a and process ring b are respectively installed on the two end faces of the conical structure resource compartment. Process ring a is a cylindrical structure, its cylindrical surface is in contact with the arc surface of support platform a, and its end face is in contact with and limited by the end face of support platform a.

[0012] The process ring b is provided with a support shaft, and the cylindrical surface of the support shaft fits and limits the V-groove of the limiting frame.

[0013] According to one embodiment of the present invention, the bottom of the parking rack is provided with a height-adjustable jack to keep the device in a horizontal position.

[0014] According to one embodiment of the present invention, both support platform a and support platform b are provided with vertical surfaces, the vertical surfaces are at an angle of 90° to the plane of the parking rack, and are connected to the parking rack by diagonal braces.

[0015] According to one embodiment of the present invention, the support platform b includes a first support platform and a second support platform, and an opening is provided between the first support platform and the second support platform to avoid the equipment envelope on the resource compartment.

[0016] According to one embodiment of the present invention, process ring a and process ring b are respectively provided with lifting point a and lifting point b, which are used to cooperate with the lifting device to realize the horizontal lifting of the resource compartment.

[0017] According to one embodiment of the present invention, the two-dimensional adjustment mechanism is used to adjust the position of the limiting frame in the horizontal plane to accommodate the fit error between the support shaft of the process ring b and the V-groove.

[0018] According to one embodiment of the present invention, the limiting frame includes a base, a supporting vertical plate, and an upper cover plate. The supporting vertical plate is fixed in the middle of the base, and the upper end face of the supporting vertical plate is provided with the V-shaped groove. The upper cover plate cooperates with the supporting vertical plate to limit the process ring b.

[0019] Because of the adoption of the above technical solution, this utility model has the following advantages and positive effects compared with the prior art:

[0020] The conical resource module horizontal parking device in one embodiment of this utility model forms a "three-point, one-surface" constraint through the arc surface and end face of support platform a, and the V-groove and support shaft of support platform b. This ensures the stable load-bearing of the module and naturally avoids the protruding solar panel support, engine, and antenna outside the conical module, solving the problem of not being able to simultaneously achieve horizontal parking while maintaining a complex external envelope. It completes the horizontal parking of the conical module and the leveling of the equipment mounting surface in one go using a purely mechanical method. This achieves horizontal parking of the equipment mounting surface on the conical resource module at a relatively low cost and adapts to the complex external envelope state of the conical resource module, meeting the horizontal parking requirements of the Tiangong space station experimental module.

Detailed Implementation

[0030] The present invention provides a conical resource compartment horizontal parking device in further detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description and claims.

[0031] Please refer to Figures 1 to 3 This embodiment provides a horizontal parking device for a conical resource compartment, including: a parking frame 1, a two-dimensional adjustment mechanism 2, a limiting frame 3, a process ring a4, and a process ring b5. The parking frame 1 is a flat truss structure with a height-adjustable jack at the bottom. Support platforms a101 and b102 are respectively provided at both ends of the parking frame. The two-dimensional adjustment mechanism 2 is installed on the support platform b102. The limiting frame 3 is installed on the two-dimensional adjustment mechanism 2 and moves in the plane with the two-dimensional adjustment mechanism. The limiting frame 3 is provided with a V-groove 301. The process rings a and b are respectively installed on the two end faces of the resource compartment 6. The process ring a4 is a cylindrical structure, and its cylindrical surface fits against the arc surface of the support platform a101. Its end face fits against and limits the end face of the support platform a101. The process ring b5 is provided with a support shaft, and the cylindrical surface of the support shaft fits against and limits the V-groove of the limiting frame.

[0032] The device uses a collaborative structure of parking frame + double support platform + two-dimensional adjustment mechanism + double process ring + V-groove to complete the horizontal parking of the conical cabin and the leveling of the equipment installation surface in one go in a purely mechanical manner. It eliminates the need for a high-cost two-dimensional turntable, reducing development and maintenance costs by more than 60%.

[0033] Specifically, the parking rack 1 is welded from steel pipes, and the bottom is equipped with height-adjustable jacks 104. Furthermore, jacks 104 are installed at all four corners of the parking rack 1, which can be raised and lowered simultaneously or independently to quickly and accurately adjust the entire "parking rack + conical resource compartment" to the required horizontal position, so that the installation surface of the equipment to be installed on the resource compartment is parallel to the horizontal plane, meeting the installation requirements of high-precision equipment such as solar panels, engines, and antennas.

[0034] The upper surface of the parking rack 1 is provided with support platform a101 and two support platforms b102 at opposite ends. Please refer to [reference needed]. Figure 4 The support platform a101 has an arc surface 105 and an end abutment surface 106. The side of the support platform a101 facing the support platform b102 is the vertical surface a108, which has an angle of 90° with the plane of the parking rack. The other side is fixed to the flat truss structure of the parking rack through the diagonal brace a107.

[0035] Two support platforms b102 are independently installed on the parking rack 1, with a certain distance between them. To avoid the envelopment of equipment on the resource compartment 6, the two support platforms b102 are spaced apart by a gap 111. The side of support platform b102 facing support platform a101 is the vertical surface b110, which forms a 90° angle with the plane of the parking rack. Its other side is fixed to the flat truss structure of the parking rack through diagonal brace b.

[0036] A two-dimensional adjustment mechanism 2 is fixedly mounted on the upper surface of each support platform b102. A limiting frame 3 is fixedly mounted on the two-dimensional adjustment mechanism 2, and the limiting frame 3 moves bidirectionally within the plane along with the two-dimensional adjustment mechanism 2. Please refer to [link / reference]. Figure 5 The limiting frame 3 includes a base 301, a supporting vertical plate 302, and an upper cover plate 303. The supporting vertical plate 302 is fixed in the middle of the base 301, and a V-groove 304 is opened on the upper end surface of the supporting vertical plate 302. The upper cover plate 303 cooperates with the supporting vertical plate 302 to realize the limiting of the process ring b.

[0037] The aforementioned two-dimensional adjustment mechanism 2 can be a planetary roller screw + linear bearing combination platform. This structure has a large load-bearing capacity and good rigidity, and can be used in large-diameter heavy-duty conical cabins. With the help of a dial, it can achieve millimeter-level coarse adjustment and 0.1 mm-level fine adjustment. Alternatively, it can be a wedge-sloping surface fine adjustment mechanism, with a pair of wedges in each of the X and Y directions. By rotating the double-ended screw, the wedges slide relative to each other, producing a continuous micro-displacement of 0–20 mm. The structure has a low height and is suitable for the internal arrangement of parking racks with limited space.

[0038] The two-dimensional adjustment mechanism allows for bidirectional movement within a plane, enabling the V-groove and the process ring support shaft to automatically align during the cabin descent process. This reduces the fit error from the traditional ±2 mm to ±10 mm, shortens the assembly alignment time from several hours to less than 30 minutes, and lowers the relative fit accuracy requirements for support platforms a101 and b102.

[0039] Please refer to Figure 6 The process ring a4 is a cylindrical structure, which is fitted outside the resource compartment 6. Its cylindrical surface 401 is in contact with the arc surface 105 of the support platform a101, and its end face 402 is in contact with and limited by the end face 106 of the support platform a101.

[0040] Please refer to Figure 7 The process ring b5 is provided with a support shaft 501. The cylindrical surface of the support shaft 501 fits into the V-groove 304 of the limiting frame 3 and is limited by the cover plate 303.

[0041] Process rings a4 and b5 are respectively equipped with lifting points a403 and b502, which are used in conjunction with the lifting equipment to achieve horizontal lifting of the resource compartment.

[0042] The arc surface of support platform a plus the end face, and the V-groove of support platform b plus the support shaft form a "three-point and one-surface" constraint, which not only ensures the stable load-bearing of the cabin, but also naturally avoids the solar panel bracket, engine and antenna protruding from the conical cabin, solving the problem of not being able to balance complex outer envelope and horizontal parking.

[0043] Process rings a and b serve as reusable transition interfaces, enabling the same set of devices to be quickly adapted to a series of resource modules with different cone angles and diameters, significantly improving versatility and meeting the economic management needs of ground equipment for small-batch, multi-model spacecraft.

[0044] In practical applications, the method of using this conical resource compartment horizontal parking device includes the following steps:

[0045] The first step is to park and secure the horizontal parking device in place;

[0046] The second step is to install process ring a and process ring b on the conical resource compartment.

[0047] The third step is to use a lifting device to horizontally lift the conical resource compartment through lifting point a on process ring a and lifting point b on process ring b.

[0048] The fourth step is to lower the conical resource compartment to a position about 200-300mm above support platform a and support platform b, and then lower process ring a so that the end face of process ring a mates with the end face of support platform a, and the cylindrical surface of process ring a initially fits with the arc surface of support platform a.

[0049] Fifth step: Lower process ring b, and at the same time adjust the two-dimensional adjustment mechanism so that the cylindrical surface of the support shaft on process ring b is initially in contact with the V-groove of the limit frame;

[0050] Step 6: Simultaneously lower process ring a and process ring b so that the cylindrical surface of process ring a is in complete contact with the arc surface of support platform a, and the cylindrical surface of the support shaft on process ring b is in complete contact with the V-groove of the limit frame.

[0051] The seventh step is to adjust the height of the jacks to ensure that the installation surface of the conical resource compartment equipment is parallel to the horizontal plane.

[0052] In summary, this conical resource module horizontal mounting device includes a mounting frame, a two-dimensional adjustment mechanism, a limiting frame, process ring a, and process ring b. The mounting frame is a flat truss structure with adjustable jacks at the bottom, and support platforms a and two support platforms b are located at both ends. Process rings a and b are pre-fixed to both ends of the conical resource module and are horizontally lifted by a lifting device, so that process ring a is in contact with the arc surface and end face of support platform a, and the support shaft of process ring b is in contact with the V-groove of the limiting frame installed on the two-dimensional adjustment mechanism. The two-dimensional adjustment mechanism can move bidirectionally in the plane to quickly compensate for alignment errors and is leveled with the help of jacks to achieve parallelism between the equipment mounting surface of the resource module and the horizontal plane. This device meets the complex outer envelope avoidance requirements of the conical module with a simple structure, and is low in cost, short in cycle, and has good versatility. It is suitable for the horizontal assembly of conical spacecraft such as space station experimental modules.

Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they shall still fall within the protection scope of the present invention.
