Description

Technical Field

[0001] This invention belongs to the field of hoisting technology in the development process of typical large-size flat-panel satellites for spacecraft, and relates to a modular floating hoisting device, specifically a high-load-bearing, high-reliability modular hoisting component device for large-size flat-panel satellites. Background Technology

[0002] With the rise of large-scale deployment of low-Earth orbit (LEO) internet constellations, large-size flat-panel satellites have been widely adopted due to their compact structure and ease of stacking for launch. The large-scale manufacturing of flat-panel satellites has become a crucial guarantee for large-scale constellation construction. During the manufacturing process, flat-panel satellites require frequent transfers to different workstations, testing equipment, and experimental facilities depending on the specific work project. Achieving efficient and reliable hoisting and relocation operations is a critical aspect affecting the smooth and efficient operation of the entire production process. Throughout the hoisting process, ensuring precise and reliable docking between the hoisting device and the satellite, as well as a reliable lifting connection, is paramount.

[0003] Patent CN203558705U provides a comprehensive hoisting device for drive rod assemblies, including an outer clamping component, an inner clamping component, an upper base plate, a connecting rod, a lifting ring, and a telescopic device. This utility model relates to the nuclear industry and avoids the problem of existing auxiliary tools having only one function. During hot-state experiments, there is no need to switch between hoisting auxiliary tools and interlocking / unlocking auxiliary tools, making it convenient to use and improving work efficiency.

[0004] Patent CN116177201A provides a satellite panel gripping device for mass mixed-line production, including a clamping mechanism for clamping and fixing satellite panels; the clamping mechanism includes a main body, a displacement plate disposed on the main body that can move closer or further apart from each other along a first direction, a rotation adjustment structure disposed on the displacement plate, and a gripper fixedly connected to the rotation adjustment structure; the rotation adjustment structure is configured to drive the gripper to rotate relative to the displacement plate about a third direction as an axis, thereby adjusting the clamping angle of the gripper when clamping the satellite panel; in the same plane, the first direction is perpendicular to the third direction.

[0005] However, neither CN203558705U nor CN116177201A has a floating adaptive function, which cannot effectively reduce the requirements for hoisting docking accuracy and the accuracy matching between the hoisting tool and the hoisting interface. Summary of the Invention

[0027] Four sets of transverse actuating cylinders 11 are installed around the component mounting base 1. After the four sets of transverse actuating cylinders 11 extend, they clamp the transverse sliding mounting base 3 and the longitudinal sliding mounting base 2 respectively.

[0028] The load cell 5 is mounted on the longitudinal sliding mounting base 2; the load cell 5 adopts a hollow structure, with the hoisting rod assembly 6 installed in the middle.

[0029] The lifting rod assembly 6 is installed on the upper end of the load cell 5 and extends through the center hole of the load cell 5. The vertical actuation cylinder 10 is connected to the mounting flange on the lifting rod assembly 6, and the extension rod inside the vertical actuation cylinder 10 is connected to the cylinder actuation extension rod 602 in the lifting rod assembly 6.

[0030] The component mounting base 1 is welded from aluminum alloy sheet. The component mounting base has a square box-shaped structure. The upper flange is used for mounting this part, and the four corners are machined with mounting holes for installing and fixing the entire component device.

Figure 7 As shown, the protective cover 4 has a frame made of bent aluminum alloy sheet. The frame is provided with mounting lugs around the perimeter and is connected and fixed to the component mounting base 1. The bottom center of the protective cover 4 is made of a polymer elastic membrane material. This elastic membrane material is bonded to the frame of the protective cover 4 and the lifting rod assembly 6 by means of silicone rubber bonding, so as to achieve overall protection of the bottom of the component and prevent extraneous objects from falling.

[0036] The longitudinal linear guide assembly 8, the transverse linear guide assembly 9, the vertical actuation cylinder 10, the transverse actuation cylinder 11, and the weighing sensor 5 are all conventional and mature products used in the field of industrial automation, with high reliability. The longitudinal linear guide assembly 8 and the transverse linear guide assembly 9 are both installed in a downward pressing manner, which greatly improves the safety of the linear guide assembly.

[0037] Four sets of reset spring assemblies 7 are respectively installed in two opposing groups between the component mounting base 1 and the transverse sliding mounting base 3, and between the transverse sliding mounting base 3 and the longitudinal sliding mounting base 2.

[0038] Among them, the two sets of return spring assemblies 7 installed on the component mounting base 1 and the transverse sliding mounting base 3 are used to realize the initial reset of the transverse sliding mounting base 3, and the transverse actuation cylinder 11 is in the retracted state.

[0039] Two sets of return spring assemblies 7 installed between the transverse sliding mounting base 3 and the longitudinal sliding mounting base 2 are used to achieve the initial reset of the longitudinal sliding mounting base 2, while the transverse actuating cylinder 11 is in the retracted state.

[0040] The reset spring assembly 7 includes: a reset spring guide rod 701, a reset spring mounting base 702, and a reset spring 703. Each set of reset spring guide rod 701, reset spring mounting base 702, and reset spring 703 is assembled in series. The lateral floating force can be adjusted by adjusting the pre-compression of the reset spring 703.

[0041] The lifting rod assembly 6 is the main functional component for achieving assembly docking and lifting. The lifting rod assembly 6 includes an upper sleeve 601, a cylinder-actuated extension rod 602, an outward-folding wedge block 603, a middle sleeve 604, a lifting stop block 605, a reset top block 606, a reset top block compression spring 607, and a lower tapered section 608 of the lifting rod. The lower mounting surface of the upper flange of the upper sleeve 601 is connected to the load cell 5, and its upper mounting surface is connected to the vertical actuation cylinder 10. The lower end is connected and fixed to the middle sleeve 604 of the lifting rod by a set screw. The upper sleeve has a waist shape in the middle for checking the actuation status of the middle cylinder-actuated extension rod 602. The cylinder-actuated extension rod 602 has studs and threaded holes at both ends, which are threadedly connected to the vertical actuation cylinder 11 and the outward-tilting wedge 603, respectively. The vertical actuation cylinder 11 moves the outward-tilting wedge 603 up and down via the cylinder-actuated extension rod 602. The stroke can be adjusted by adjusting the length of the cylinder-actuated extension rod 602 or the length of the threaded connection. The outward-tilting wedge 603 is made of brass and is threadedly connected to the cylinder-actuated extension rod 602. This part is mainly used to achieve the outward tilting action of the lifting stop 605. When the outward-tilting wedge 603 moves downward... The lifting stop 605 flips outwards towards the outer side of the middle sleeve 604 of the lifting rod, achieving lifting lock. The lifting stop 605 is a key component of the lifting rod assembly 6, made of high-strength steel. This component is installed to the middle sleeve 604 of the lifting rod via high-strength pins and screws. It flips outwards and retracts into the middle sleeve 604 via the outward-flipping wedge 603 and the reset top block, respectively, thus enabling the lifting rod assembly 6 to connect and disconnect from the satellite lifting hole. The lifting stop 605 is normally in the retracted state to facilitate lifting docking. The reset top block 606 is made of brass. The lifting rod can move parallel within the sleeve 604 of the lifting rod. Through the action of the reset top block compression spring 607, it applies a lifting force to the lifting stop 605, thereby realizing the retraction function of the lifting stop 605. The lower tapered section 608 of the lifting rod is made of high-strength nylon material, which has the characteristics of high strength and low friction. It adopts a tapered design to facilitate the guiding sliding function during docking with the satellite lifting hole. This part is connected to the sleeve 604 of the lifting rod by threads. The middle part is provided with a mounting hole for the reset top block compression spring 607, and the installation simultaneously realizes the clamping operation of the reset top block compression spring 607.

[0042] The hoisting assembly adopts a modular design, which can be flexibly adjusted according to changes in the number and position of satellite hoisting interfaces on the platform, thereby shortening the manufacturing cycle and cost of the hoisting device. The hoisting assembly has a floating self-adaptive function, which can effectively reduce the requirements for hoisting docking accuracy and the accuracy matching between the hoisting tool and the satellite hoisting interface, thereby achieving efficient and reliable docking. Except for the main structural components, the entire assembly widely adopts standard linear guides, load cells, cylinders and other products from the field of industrial automation, which have high safety and reliability and reduce development costs. The entire assembly has a compact configuration, and the linear guides and load cells are all installed under positive pressure, which further improves the safety and reliability of the entire device. The hoisting rod assembly has a simple design and fewer supporting parts. It only uses outward-folding wedges and reset top blocks to realize the outward-folding and retraction of the hoisting stop. The spring is in a compressed state, which has long-term stable and reliable characteristics, further improving the inherent safety and reliability of the hoisting rod assembly. The hoisting assembly is pneumatically driven and equipped with a protective cover, which fully reduces the adverse effects of foreign objects generated during the movement of various components on the satellite product.
