Description

Technical Field

[0001] The present application relates to the technical field of satellite assembly, and in particular to a satellite assembly support vehicle. Background Art

[0002] Due to the complexity of satellite product development technology, involving multiple disciplines such as control, propulsion, thermal control, payload, and structural mechanism, coupled with the continuous changes in user needs, the functional requirements for satellite support vehicles are becoming more and more diverse. Assembly support vehicles are mostly used for the assembly of spacecraft, and have the characteristics of large bearing capacity, high structural accuracy and stability. During the assembly process, satellites need to have different postures to facilitate equipment installation and structural plate assembly; at the same time, during the installation of solar panels on some satellites, satellites need to be in a vertical state; and some satellites need to have different states when carrying large SAR antennas and other payloads. Ordinary parking support vehicles can no longer meet the use requirements. Although different types of parking support vehicles can meet the use requirements, they increase costs and consume more manpower and material resources. In response to these technical problems, the invention patent application with publication number CN116160397A proposed a five-degree-of-freedom adjustment platform for satellite cabin panel assembly, but its structure is too complicated, resulting in a greater probability of failure, and thus a technical problem of low reliability. Summary of the invention

[0003] The purpose of the present application is to provide a satellite assembly support vehicle in view of at least one technical problem involved in the background technology.

[0004] In order to achieve the above objectives, this application adopts the following technical solutions: The present application provides a satellite assembly bracket vehicle, comprising a bracket, a flip platform and a rotation drive member, wherein the flip platform is pivotally connected to the top of the bracket via a rotating shaft extending in a horizontal direction, the rotation drive member is installed on the bracket, the rotation drive member is used to drive the flip platform to rotate relative to the bracket, and the rotation drive member is used to limit the position of the flip platform relative to the bracket, and the flip platform is used to connect to the satellite; The rotating driving member is a worm gear device, which includes a body and a worm mounted on the body, and the worm is pivotally connected to the flip platform; the body is pivotally connected to the bracket through a horizontally arranged shaft.

[0005] Optionally, the flip platform includes a support plate and an adapter plate, the support plate is pivotally connected to the bracket, and the adapter plate is detachably fixed to the support plate.

[0006] The beneficial effect of this technical solution is that in this way, the satellite assembly bracket vehicle provided by the present application can be used for different satellites by replacing different adapter plates according to different satellite mechanical interfaces.

[0007] Optionally, the flip platform is used to rotate between a horizontal setting state and a vertical setting state.

[0008] The beneficial effect of this technical solution is that: the flip platform described in the embodiment of the present application is used in a horizontal setting state, which means that the upper surface of the flip platform is horizontally set, and the flip platform described in the embodiment of the present application is used in a vertical setting state, which means that the upper surface of the flip platform is vertically set.

[0009] Optionally, the bracket includes a buffer pad and a vertically arranged support rod, the flip platform and the body are both pivotally connected to the support rod, the buffer pad is fixed to the support rod, and the buffer pad is used to contact the flip platform in a vertically arranged state.

[0010] The beneficial effect of this technical solution is that when the flip platform rotates from a horizontal state to a vertical state, it is not easy to directly contact the support rod, and when the flip platform is in a vertically set state and assembly-related operations are performed on the satellite on the flip platform, it is difficult for the flip platform and the support rod to be repeatedly rigidly collided, and thus it is not easy for the flip platform and / or the support rod to be damaged due to rigid contact, thereby extending the service life of the satellite assembly bracket vehicle.

[0011] Optionally, the worm gear device further includes a first hand wheel, the first hand wheel is mounted on the body, and the first hand wheel is used to drive the worm to move.

[0012] The beneficial effect of this technical solution is that: in this way, the staff can realize the movement of the worm by rotating the first hand wheel, which is convenient for operation.

[0013] Optionally, the support plate and the adapter plate are parallel to each other, and the adapter plate is located on a side of the support plate facing away from the bracket.

[0014] The beneficial effect of this technical solution is that in this way, a suitable adapter plate can be selected according to the structure and working conditions of the satellite, further improving the applicability of the satellite assembly bracket vehicle.

[0015] Optionally, the bracket includes a universal wheel, a chassis and a vertically arranged support rod, the universal wheel is fixed to the chassis, the flip platform is pivotally connected to the top end of the support rod, the bottom end of the support rod is fixed to the chassis, and a traction handle is installed on the support rod.

[0017] Optionally, the bracket includes two support rods, the flip platform is pivotally connected to the two support rods, and the body is pivotally connected to the two support rods.

[0018] Optionally, the bracket further comprises a locking assembly, wherein the locking assembly is mounted on the chassis and is used for pressure contact with the ground.

[0019] The beneficial effect of this technical solution is that, by locking the assembly in pressure contact with the ground, the entire bracket is not easily moved under the action of external forces, thereby improving the stability and reliability of the satellite assembly bracket vehicle.

[0021] The beneficial effect of this technical solution is that: in this way, the shell raises and lowers the contact piece by rotating the second hand wheel. When the satellite assembly bracket vehicle needs to be fixed at a certain position, the second hand wheel is rotated to make the contact piece continuously descend relative to the chassis and finally make pressure contact with the ground. When the satellite assembly bracket vehicle needs to be moved, the second hand wheel is rotated to make the contact piece continuously rise relative to the chassis until the contact piece is separated from the ground and the satellite assembly bracket vehicle can move smoothly.

[0022] The technical solution provided by this application can achieve at least one of the following beneficial effects: The satellite assembly bracket vehicle provided in the present application adopts a worm gear device to realize the flipping of the flipping platform, and the worm gear is directly pivoted to the flipping platform, and the main body is pivoted to the bracket. There is no need to separately provide a rod-like structure for flipping the flipping platform and the corresponding connection points of the rod-like structure.

[0023] The satellite assembly bracket vehicle provided in the present application uses the rotating drive component to drive the flip platform to rotate relative to the bracket on a vertical plane, and the rotating drive component is used to limit the position of the flip platform relative to the bracket.

DETAILED DESCRIPTION

[0028] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0030] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0031] like Figure 1 and Figure 2 As shown, the present application provides a satellite assembly bracket vehicle, including a bracket 4, a flip platform 21 and a rotating drive member, wherein the flip platform 21 is pivoted to the top of the bracket 4 through a rotating shaft 12 extending in the horizontal direction, and the rotating drive member is installed on the bracket 4, and the rotating drive member is used to drive the flip platform 21 to rotate relative to the bracket 4, and the rotating drive member is used to limit the position of the flip platform 21 relative to the bracket 4, and the flip platform 21 is used to connect to the satellite; the rotating drive member is a worm gear device, and the worm gear device includes a main body 3 and a worm 23 installed on the main body 3, and the worm 23 is pivoted to the flip platform 21; the main body 3 is pivoted to the bracket 4 through a horizontally arranged axis.

[0032] In the invention patent application with publication number CN116160397A, the flipping mechanism includes a slider that slides and fits on the rotating plate along the height direction of the platform body, a screw that is threadedly fitted on the slider, and a support rod. The slider is a T-block that slides and fits in the T-slot. The screw is arranged along the height direction of the platform body. The rotating plate supports the screw for rotation, and the screw is used to drive the slider to slide. One end of the support rod is rotationally fitted on the placement rack, and the other end is rotationally fitted on the slider. When the screw rotates, it drives the slider to rise and fall, which can drive the support rod to rotate, and then drive the placement rack to flip and adjust. In other words, the driving member drives the screw, the screw drives the slider, the slider drives the support rod, and the support rod drives the placement rack to realize the flipping of the placement rack. This structure has many components and many connection relationships, so the failure rate is high and the reliability is low.

[0033] The satellite assembly bracket vehicle provided in the present application adopts a worm gear device to realize the flipping of the flipping platform 21, and the worm gear 23 is directly pivoted to the flipping platform 21, and the main body 3 is pivoted to the bracket 4. There is no need to separately provide a rod-like structure for flipping the flipping platform 21 and the corresponding connection points of the rod-like structure. In other words, fewer components and connection points are used to realize the flipping of the flipping platform, thereby simplifying the structural components and connection relationships of the satellite assembly bracket vehicle, reducing the failure rate, and improving reliability.

[0034] When the worm gear device is started, the worm 23 can drive the flip platform 21 to rotate. When the worm 23 stops moving, the position of the flip platform 21 is limited because the relative position between the worm 23 and the body 3 is fixed, which plays a role in limiting the flip platform 21 to a certain position. Of course, the rotation drive member can also be an electric motor.

[0035] The satellite assembly bracket vehicle provided in the present application enables the rotating drive component to drive the flip platform 21 to rotate relative to the bracket 4 on a vertical plane, and the rotating drive component is used to limit the position of the flip platform 21 relative to the bracket 4. The flip platform 21 is used to be connected to the satellite, so that the flip platform 21 can adjust its position and be fixed to a certain position, thereby expanding the working conditions in which the satellite assembly bracket vehicle can be used and improving the applicability of the satellite assembly bracket vehicle.

[0036] Optionally, the flip platform 21 includes a support plate 2 and an adapter plate 1, wherein the support plate 2 is pivotally connected to the bracket 4, and the adapter plate 1 is detachably fixed to the support plate 2. In this way, the satellite assembly bracket vehicle provided in the present application can be used for different satellites by replacing different adapter plates 1 according to different satellite mechanical interfaces.

[0037] Optionally, the flip platform 21 is used to rotate between a horizontal setting state and a vertical setting state. The flip platform 21 described in the embodiment of the present application is used to be in a horizontal setting state, which means that the upper surface of the flip platform 21 is horizontally set, and the flip platform 21 described in the embodiment of the present application is used to be in a vertical setting state, which means that the upper surface of the flip platform 21 is vertically set. In other words, the flip platform 21 can be flipped 90 degrees to meet most working conditions of satellite assembly.

[0038] Optionally, the bracket 4 includes a buffer pad 10 and a vertically arranged support rod 22, the flip platform 21 and the main body 3 are both pivotally connected to the support rod 22, the buffer pad 10 is fixed to the support rod 22, and the buffer pad 10 is used to contact the flip platform 21 in a vertically arranged state. In this way, when the flip platform 21 rotates from a horizontal state to a vertical state, it is not easy to directly contact the support rod 22, and when the flip platform 21 is in a vertically arranged state, when performing assembly-related operations on the satellite on the flip platform 21, it is difficult to have repeated rigid collisions between the flip platform 21 and the support rod 22, and thus it is not easy to cause damage to the flip platform 21 and / or the support rod 22 due to rigid contact, thereby extending the service life of the satellite assembly bracket vehicle. Preferably, the flip platform 21 is pivotally connected to the support rod 22 through a connecting plate 15.

[0039] Optionally, the worm gear device further includes a first hand wheel 13, which is mounted on the body 3 and is used to drive the worm 23 to move. In this way, the staff can move the worm 23 by turning the first hand wheel 13, which is convenient for operation. Of course, the first hand wheel 13 can also be replaced by a driving member such as an electric motor. In the embodiment of the present application, the worm gear device is preferably a worm gear device of model SWL2.5T (500KG) manufactured by Jinan Pentium Machinery Co., Ltd.

[0040] Optionally, the support plate 2 and the adapter plate 1 are parallel to each other, and the adapter plate 1 is located on the side of the support plate 2 away from the bracket 4. In this way, a suitable adapter plate 1 can be selected according to the structure and working conditions of the satellite, further improving the applicability of the satellite assembly bracket vehicle.

[0041] Optionally, the bracket 4 includes a universal wheel 6, a chassis 8 and a vertically arranged support rod 22, the universal wheel 6 is fixed to the chassis 8, the flip platform 21 is pivoted to the top of the support rod 22, the bottom of the support rod 22 is fixed to the chassis 8, and a traction handle 14 is installed on the support rod 22. In this way, it is convenient for the staff to hold the traction handle 14 to move the entire satellite assembly bracket vehicle. Preferably, the bracket 4 includes two universal wheels 6 and two directional wheels 7, the chassis 8 is a square plate, and the wheels are distributed one by one at the positions of the corners of the chassis 8.

[0042] Optionally, the bracket includes two support rods 22 , the flip platform 21 is pivotally connected to the two support rods 22 , and the body 3 is pivotally connected to the two support rods 22 .

[0043] Optionally, the bracket 4 further includes a locking assembly 5, which is mounted on the chassis 8 and is used to be in pressure contact with the ground. In this way, the locking assembly 5 is in pressure contact with the ground, so that the bracket 4 as a whole is not easy to move under the action of external force, thereby improving the stability and reliability of the satellite assembly bracket vehicle.

[0044] Optionally, the locking assembly 5 includes a second hand wheel 18, a threaded rod 19 and a contact piece 20. A threaded hole is formed on the chassis 8 and passes through the chassis 8 in the vertical direction. The threaded rod 19 cooperates with the threaded hole. The second hand wheel 18 is located above the chassis 8, and the contact piece 20 is located below the chassis 8. The second hand wheel 18 and the contact piece 20 are both fixedly connected to the threaded rod 19. In this way, the staff raises and lowers the contact piece 20 by turning the second hand wheel 18. When the satellite assembly support vehicle needs to be fixed at a certain position, the second hand wheel 18 is turned to make the contact piece 20 continuously descend relative to the chassis 8 and finally contact with the ground pressure. When the satellite assembly support vehicle needs to be moved, the second hand wheel 18 is turned to make the contact piece 20 continuously rise relative to the chassis 8 until the contact piece 20 is separated from the ground and the satellite assembly support vehicle can be moved smoothly. The bracket 4 also includes a support 9 and a flip joint 11. A support seat 16 is fixed at the bottom of the support plate 2, and the worm 23 is pivotally connected to the support seat 16.

[0045] In order to better illustrate the satellite assembly bracket vehicle provided by the present application, the present application also provides an application example of a satellite assembly bracket vehicle. In this application example, the satellite assembly bracket vehicle can also be called a flip bracket vehicle, the support plate 2 can also be called a support plate, the worm gear device can also be called a worm gear mechanism or a worm gear elevator, the bracket 4 can also be called a support rod, the locking assembly 5 can also be called a locking support, the chassis 8 can also be called a chassis assembly or a base, the support 9 can also be called a diagonal support rod, the rotating shaft 12 can also be called a pin shaft, the first hand wheel 13 can also be called a foldable hand wheel, the traction handle 14 can also be called a handle, and the worm 23 can also be called a screw.

[0046] The application example is as follows: In response to some or all of the problems in the existing bracket vehicles, the present application provides a low-cost flippable bracket vehicle design, including: an arbitrarily removable adapter plate, which can be used for different satellite mechanical interfaces by replacing different adapter plates to meet the needs of different satellites; the flip function is achieved through a worm gear, which can meet the maximum flipping angle of 90°; it includes a 90° limit device, which stops flipping when it flips to 90° through a rubber pad design, and can be locked when rotated to any angle.

[0047] The main structure of the flip support vehicle consists of chassis components, directional wheels, diagonal braces, buffer pads, adapter plates, locking supports, universal wheels, worm gear lifts and foldable hand wheels. The main structure is made of Q345 material, and the structural parts welded to the main structure are made of Q345 structural steel. The local bearing structural parts and moving parts of the posture adjustment head are made of 45# steel.

[0048] The base of the trolley includes two fixed wheels and two universal wheels, which are convenient for transporting and walking. The base of the trolley also includes two locking supports for locking the position of the trolley during use, which can be locked by hand. The base also includes the mounting bases for the fixed wheels and universal wheels and the mounting welding pieces for the support frame.

[0049] The support part of the support vehicle includes two support rods connecting the base and the flip platform. The two support rods are connected and fixed to each other through a crossbar, and the crossbar provides an installation interface for the lift. A buffer pad is installed on the side of the support rod for 90° flipping. Two handles are installed on the back of the buffer pad for towing the mobile support vehicle. The support rod and the base are connected and fixed by a diagonal brace.

[0050] The flip platform consists of an adapter plate, a support plate, a worm gear lifter, and a foldable handwheel. The adapter plate is connected to the support plate by 12 M6 screws. It can be used for different satellites and different working conditions by replacing the adapter plate. The support plate is connected to the flip joint through the support seat, the flip joint is fixed to the support rod by screws, and the flip joint and the support seat are connected by a pin.

[0051] One end of the screw rod is connected to the support plate through a joint and a screw rod connection seat, and the other end is connected to the foldable hand wheel through a worm gear. The foldable hand wheel has the characteristics of being portable and hand-cranked.

[0052] The design of the support vehicle in the application is reliably connected and fixed, using conventional Q345 steel and 2A12 aluminum alloy, assembled by welding and screwing, with low cost and high reliability.

[0053] The bracket vehicle applied for can be suitable for use with different satellites by replacing the adapter plate connected to the satellite, which changes the shortcoming of traditional bracket vehicles that are only suitable for a single satellite, reduces the demand for bracket vehicles for different satellites, and reduces the cost of satellite development.

[0054] The support vehicle in this application has a flipping function, which can realize the flipping of the satellite platform through the worm gear, meeting the satellite flipping requirements during the satellite assembly process, and also meeting the requirements for changing the satellite attitude during the installation and deployment test of the satellite solar wing. For the requirements for the satellite attitude under different working conditions, the worm gear can be used to maintain the satellite attitude at any angle between 0° and 90°.

[0055] The support vehicle in the application has two universal wheels and two fixed wheels, which can be easily moved by manpower and can be fixed in position by supporting wheels, making it easy to operate and portable.

[0056] The support vehicle applied for has a limiting function through a buffer pad to prevent the worm gear from being subjected to concentrated force and damaging the structure after flipping over 90°.

[0057] The flippable support vehicle has a 90° flip function through a worm gear mechanism, and can be locked and paused at any angle. A buffer limiter is designed at the 90° position to prevent the support vehicle from flipping over 90° when the satellite flips. On the other hand, when the satellite flips on the support vehicle, the vertical state has a buffering effect to prevent impact and collision on the satellite.

[0058] The satellite support vehicle of the present application can be used for different satellites by replacing the adapter plate connected to the satellite, and can be applied to different satellites. By using one vehicle for multiple purposes, the development cost of the satellite can be reduced. Different angles can meet the requirements for different attitudes of the satellite during satellite assembly and testing. The satellite needs to be in a vertical state during the installation and deployment test of the solar wing, and the satellite may need to be flipped at different angles when installing the equipment in the cabin. The support vehicle in the present application can meet all these requirements.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it.
