Description

Technical Field

[0001] This application relates to the field of devices for satellite assembly, and in particular to an auxiliary device for ground assembly of low-orbit satellites. Background Art

[0002] Low-orbit satellites are mainly used for military target detection, and it is easy to obtain high-resolution images of targets using low-orbit satellites; low-orbit satellites are also used for mobile communication. The low orbit height of the satellites results in short transmission delays and small path losses.

[0003] During the process of assembling the satellite main body, the operator needs to use a hoisting tool to suspend the satellite main body and fix the satellite main body through a clamping device arranged on the ground. The operator stands on the lifting equipment. When assembling different parts of the satellite main body, the operator needs to move the lifting equipment to adjust the assembly position.

[0004] When moving the lifting equipment, to ensure the safety of the operator, the operator needs to get down to the ground and then move the lifting equipment. After the lifting equipment is moved to the predetermined position, the operator gets back on the lifting equipment to continue the assembly of the satellite main body. The steps for the operator to adjust the assembly position are cumbersome, resulting in low efficiency of ground assembly of low-orbit satellites. Summary of the Invention

[0005] In order to improve the efficiency of ground assembly of low-orbit satellites, this application provides an auxiliary device for ground assembly of low-orbit satellites.

[0006] The auxiliary device for ground assembly of low-orbit satellites provided by this application adopts the following technical solutions:

[0007] An auxiliary device for ground assembly of low-orbit satellites includes a bottom plate, a middle plate is rotatably connected to the bottom plate, a placing plate is slidably connected to the middle plate, the placing plate is located above the middle plate, a clamping assembly for fixing the satellite main body is arranged between the placing plate and the middle plate, a driving motor is fixedly connected to the bottom plate, a driving gear is fixedly connected to the output shaft of the driving motor, and a driven gear meshing with the driving gear is fixedly connected to the lower surface of the middle plate.

[0008] By adopting the above technical solution, when an operator needs to assemble the satellite body, first place the satellite body on the placement plate through a hoisting device. The force exerted by the satellite body on the placement plate drives the clamping assembly to work. The clamping assembly works to clamp the satellite body, thereby fixing the satellite body. When the operator needs to change the assembly position of the satellite body, start the driving motor. The output shaft of the driving motor rotates to drive the driving gear, the driven gear, and the middle layer plate to rotate. The rotation of the middle layer plate drives the placement plate to rotate, and the rotation of the placement plate drives the satellite body to rotate, thereby changing the assembly position of the satellite body, reducing the time consumed in assembling the satellite body, and improving the efficiency of ground assembly of low-orbit satellites.

[0009] Optionally, the clamping assembly includes two clamping plates slidably connected to the placement plate. A support rod is fixedly connected to the clamping plate. The support rod is slidably inserted into the placement plate and slides along the sliding direction of the clamping plate. A strip-shaped hole corresponding to the support rod is formed in the middle layer plate. The length direction of the strip-shaped hole is arranged along the sliding direction of the support rod. The support rod is slidably inserted into the strip-shaped hole. An installation block is slidably inserted into the support rod, and the installation block is slidably inserted into the strip-shaped hole. A return spring is fixedly connected to the side walls of the two installation blocks facing away from each other. The end of the return spring away from the installation block is fixedly connected to the hole wall at the corresponding end of the strip-shaped hole. A hinge rod is hinged to the side walls of the two installation blocks facing each other. One end of a connecting rod is hinged to the end of one hinge rod away from the installation block. The connecting rod is located below the middle layer plate. The end of the other hinge rod away from the installation block is also hinged to the connecting rod. A guide rod is fixedly connected to the lower surface of the placement plate. The guide rod is slidably inserted into the middle layer plate and is fixedly connected to the connecting rod. A plurality of support springs are also fixedly connected to the lower surface of the placement plate. The lower ends of the support springs are fixedly connected to the upper surface of the middle layer plate.

[0010] By adopting the above technical solution, in the initial state, both the support spring and the return spring are in a natural state, and the upper ends of the two hinge rods are inclined away from each other. When the operator places the satellite body on the placement plate through a hoisting device, the satellite body is located between the two clamping plates. The satellite body presses the placement plate to move downward. The movement of the placement plate drives the guide rod and the connecting rod to move downward. The movement of the connecting rod pulls the lower end of the hinge rod to move downward. While the hinge rod moves, it rotates. The upper ends of the two hinge rods rotate towards each other. The rotation of the hinge rod drives the installation block, the support rod, and the clamping plate to move, so that the two clamping plates move towards each other, and the two clamping plates cooperate to clamp the satellite body to fix the satellite body. While the installation block moves, the installation block pulls the return spring to deform the return spring.

[0011] When it is necessary to take out the satellite main body, the operator pulls the satellite main body upward through the lifting device. While the satellite main body moves, the supporting spring restores its deformation. The supporting spring restores its deformation and pushes the placing plate, the guiding rod, the connecting rod and the supporting rod upward. At the same time, the reset spring restores its deformation and pulls the mounting block and the supporting rod to move. The movement of the supporting rod drives the clamping plate to move, so that the two clamping plates move away from each other. When both clamping plates move to be disengaged from the satellite main body, the operator can continue to pull the satellite main body upward through the lifting device, so as to take out the satellite main body; when both the supporting spring and the reset spring return to their natural states, the clamping plate returns to its initial position.

[0012] Optionally, a fastener for further clamping the satellite body is provided on the bottom plate.

[0013] By adopting the above technical solution, the fastener works to further clamp the satellite, making the effect of fixing the satellite body better.

[0014] Optionally, the fastener includes a rope winding wheel fixedly connected to one end face of the driving gear. A pulling rope is wound around the rope winding wheel, and one end of the pulling rope is fixedly connected to the connecting rod.

[0015] By adopting the above technical solution, when the driving gear rotates, the driving gear drives the rope winding wheel to rotate. The rope winding wheel winds the pulling rope onto the rope winding wheel. While the pulling rope is wound onto the rope winding wheel, the pulling rope pulls the connecting rod downward. The movement of the connecting rod drives the articulated rod to rotate. The rotation of the articulated rod drives the mounting block, the supporting rod and the clamping plate to move, so that the two clamping plates continue to move closer to each other, and the two clamping plates can better fix the satellite body.

[0016] Optionally, a plurality of sliders are fixedly connected to the lower surface of the clamping plate. Sliding grooves corresponding to the sliders one by one are formed on the upper surface of the placing plate. Each slider is slidably inserted into the corresponding sliding groove. A sliding hole penetrating the placing plate is formed on the placing plate. The length direction of the sliding hole is arranged along the moving direction of the clamping plate. The supporting rod is slidably inserted into the sliding hole.

[0017] By adopting the above technical solution, the movement of the clamping plate drives the slider to move along the sliding groove. The cooperation between the slider and the sliding groove makes the clamping plate slidably connected to the placing plate.

[0018] Optionally, a ring plate is fixedly connected to the lower surface of the middle layer plate. A connecting groove corresponding to the ring plate is formed on the upper surface of the bottom plate. The ring plate is inserted into the connecting groove.

[0019] By adopting the above technical solution, the rotation of the middle layer plate drives the ring plate to rotate in the connecting groove. The cooperation between the ring plate and the connecting groove makes the middle layer plate rotatably connected to the bottom plate.

[0020] Optionally, a flexible plate is fixedly connected to the side walls of the two splints that are close to each other.

[0021] By adopting the above technical solution, when the splints clamp the satellite body, the flexible plate contacts the satellite body, reducing the situation that the surface of the satellite body is worn due to the direct contact between the splints and the satellite body.

[0022] Optionally, the flexible plate is a rubber plate.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By setting the bottom plate, the middle layer plate, the placement plate, the drive motor, the driving gear, and the driven gear, the time consumed in assembling the satellite body is reduced, and the efficiency of ground assembly of low-orbit satellites is improved;

[0025] 2. By setting the splints, the support rods, the mounting blocks, the hinge rods, the guide rods, the connecting rods, the support springs, and the return springs, the satellite body can be fixed;

Detailed Description

[0032] The following is combined with the attachedFigures 1-4 A further detailed description of the present application will be given.

[0033] An embodiment of the present application discloses an auxiliary device for ground assembly of low-orbit satellites. Referring to Figure 1 , the auxiliary device includes a bottom plate 1 placed on the ground. A middle plate 2 is rotatably connected to the bottom plate 1. A placement plate 3 is slidably inserted into the middle plate 2. The middle plate 2 is located between the placement plate 3 and the bottom plate 1. A clamping assembly 4 for clamping and fixing the satellite body is provided on the placement plate 3. The satellite body is placed on the placement plate 3. A driving assembly 5 for driving the middle plate 2 to rotate is provided between the bottom plate 1 and the middle plate 2.

[0034] When an operator needs to assemble the satellite body, first place the satellite body on the placement plate 3. After the satellite is placed on the placement plate 3, it triggers the clamping assembly 4 to work. The clamping assembly 4 works to fix the satellite body. The operator stands on the lifting equipment, and the lifting equipment is placed on one side of the bottom plate 1. When it is necessary to change the assembly position of the satellite body, the operator starts the driving assembly 5. The driving assembly 5 works to make the middle plate 2 and the placement plate 3 rotate. The rotation of the placement plate 3 drives the satellite body to rotate, so as to change the assembly position of the satellite body, which is convenient for the operator to assemble the satellite body, reduces the time consumed by the operator when assembling the satellite body, and improves the efficiency of ground assembly of the orbital satellite.

[0035] Referring to Figure 1 and Figure 2 , a ring plate 21 is vertically and fixedly connected to the lower surface of the middle plate 2. The ring plate 21 is coaxially arranged with the circumcircle of the middle plate 2. A connection groove 11 corresponding to the ring plate 21 is formed on the upper surface of the bottom plate 1. The connection groove 11 is an annular groove. The ring plate 21 is inserted into the connection groove 11. The cooperation between the ring plate 21 and the connection groove 11 enables the middle plate 2 to be rotatably connected to the bottom plate 1. There is a gap between the surfaces of the bottom plate 1 and the middle plate 2 that are close to each other. A plurality of support springs 32 are fixedly connected to the lower surface of the placement plate 3. The plurality of support springs 32 are evenly distributed on the placement plate 3. One end of the support spring 32 away from the placement plate 3 is fixedly connected to the upper surface of the middle plate 2. In this embodiment, the number of support springs 32 is four, and the four support springs 32 are evenly distributed at the four end corners of the placement plate 3. When no satellite body is placed on the placement plate 3, the support springs 32 are in a natural state.

[0036] Referring to Figure 2 and Figure 3, the clamping assembly 4 includes two clamping plates 41 slidably connected to the upper surface of the placement plate 3. The two clamping plates 41 are arranged oppositely. A plurality of sliders 411 are fixedly connected to the lower surface of the clamping plate 41. The plurality of sliders 411 are arranged along the length direction of the clamping plate 41. In this embodiment, there are two sliders 411 on each clamping plate 41, and the two sliders 411 are respectively located on both sides of the clamping plate 41. A chute 31 corresponding to the slider 411 one by one is formed on the upper surface of the placement plate 3. Each slider 411 is slidably inserted into the corresponding chute 31, and the length direction of the chute 31 is arranged along the sliding direction of the clamping plate 41.

[0037] A sliding hole 33 penetrating through the placement plate 3 is formed on the placement plate 3. The length direction of the sliding hole 33 is arranged along the length direction of the chute 31. The sliding hole 33 is located between the two chutes 31. A support rod 42 corresponding to the sliding hole 33 is vertically and fixedly connected to the lower surface of the clamping plate 41. The support rod 42 is slidably inserted into the sliding hole 33. The length of the support rod 42 is greater than the distance between the upper surface of the placement plate 3 and the lower surface of the middle layer plate 2. A strip-shaped hole 22 corresponding to the support rod 42 is formed on the middle layer plate 2. The strip-shaped hole 22 is located directly below the sliding hole 33. The length direction of the strip-shaped hole 22 is arranged along the length direction of the sliding hole 33. The distance between the hole walls at the mutually remote ends of the two strip-shaped holes 22 is greater than the length of the sliding hole 33.

[0038] A mounting block 43 is slidably inserted on each support rod 42. The support rod 42 penetrates through the corresponding mounting block 43. The mounting block 43 is slidably inserted into the strip-shaped hole 22. A return spring 44 is fixedly connected to the side walls of the two mounting blocks 43 facing away from each other. The end of the return spring 44 away from the mounting block 43 is fixedly connected to the corresponding end hole wall of the strip-shaped hole 22. When the return spring 44 is in the natural state, the two support rods 42 are respectively located at both ends of the sliding hole 33.

[0039] A hinge rod 45 is hinged to the side walls of the two mounting blocks 43 facing each other. The lower end of the hinge rod 45 is located between the bottom plate 1 and the middle layer plate 2. A connecting rod 46 is provided between the lower ends of the two hinge rods 45. The connecting rod 46 is located below the middle layer plate 2. The two ends of the connecting rod 46 are respectively hinged to the lower ends of the two hinge rods 45. A guide rod 47 is vertically and fixedly connected to the lower surface of the placement plate 3. The cross section of the guide rod 47 is rectangular. The guide rod 47 is located directly above the connecting rod 46. The guide rod 47 penetrates through the middle layer plate 2 and is slidably inserted into the middle layer plate 2. The lower end of the guide rod 47 is fixedly connected to the upper surface of the connecting rod 46. The connecting rod 46 is in a horizontal state.

[0040] In the initial state, the support spring 32 is in its natural state, and the return spring 44 is also in its natural state. The upper ends of the two hinge rods 45 are inclined away from each other, and the lower ends of the two hinge rods 45 are inclined towards each other. When an operator needs to fix the satellite main body, the satellite main body is placed on the placement plate 3, and the satellite main body is located between the two clamping plates 41. The satellite main body presses the placement plate 3 to move downward. While the placement plate 3 moves, it compresses the support spring 32. The movement of the placement plate 3 drives the support rod 42 and the guide rod 47 to move downward, and the guide rod 47 moves and pushes the connecting rod 46 to move downward.

[0041] The movement of the connecting rod 46 pulls the lower ends of the two hinge rods 45 to move downward simultaneously. While the lower ends of the hinge rods 45 move, the upper ends of the hinge rods 45 rotate towards each other. The rotation of the hinge rods 45 drives the mounting blocks 43 to move, so that the two mounting blocks 43 move towards each other along the strip-shaped holes 22, and the movement of the mounting blocks 43 stretches the return spring 44.

[0042] The movement of the mounting blocks 43 drives the corresponding support rods 42 and the clamping plates 41 to move, so that the two clamping plates 41 move towards each other. The movement of the clamping plates 41 drives the sliders 411 to move along the sliding grooves 31. When both of the two clamping plates 41 are in contact with the satellite main body, as the placement plate 3 continues to move downward, the two clamping plates 41 move towards each other, so that the two clamping plates 41 cooperate to clamp the satellite main body to achieve the purpose of fixing the satellite main body. In order to reduce the possibility of the clamping plates 41 causing wear on the surface of the satellite main body, a flexible plate 412 is fixedly connected to the side walls of the two clamping plates 41 that are close to each other. In this embodiment, the material of the flexible plate 412 is a rubber plate.

[0043] When it is necessary to take out the satellite main body, the operator pulls the satellite main body upward through the lifting device. While the satellite main body moves, the support spring 32 restores its deformation and pushes the placement plate 3 to move upward. The movement of the placement plate 3 drives the guide rod 47 and the connecting rod 46 to move upward. At the same time, the return spring 44 restores its deformation and pulls the mounting blocks 43 to move, so that the two mounting blocks 43 move away from each other.

[0044] While the mounting blocks 43 move, they pull the hinge rods 45 to rotate. The movement of the mounting blocks 43 also pulls the support rods 42 and the clamping plates 41 to move, so that the two clamping plates 41 move away from each other. When the two clamping plates 41 move to be disengaged from the satellite main body, the operator continues to control the lifting device to pull the satellite main body upward, so as to take out the satellite main body. When both the support spring 32 and the return spring 44 return to their natural states, the clamping plates 41 move to the initial position.

[0045] Refer to Figure 2 And Figure 4, the driving assembly 5 includes a driven gear 53. A mounting rod 531 is fixedly connected to the lower surface of the middle layer plate 2. There is a gap between the lower end surface of the mounting rod 531 and the upper surface of the bottom plate 1. The mounting rod 531 is perpendicular to the middle layer plate 2. The driven gear 53 is fixedly connected to the lower end of the mounting rod 531. The axial direction of the driven gear 53 is arranged along the length direction of the guide rod 47. The driven gear 53 is located in the middle of the middle layer plate 2. A driving motor 51 is fixedly connected to the upper surface of the bottom plate 1. A driving gear 52 is fixedly connected to the output shaft of the driving motor 51. The axial direction of the driving gear 52 is arranged along the axial direction of the driven gear 53. The driving gear 52 meshes with the driven gear 53. When the operator needs to rotate the satellite body, the driving motor 51 is started. The output shaft of the driving motor 51 rotates to drive the driving gear 52 to rotate. The driving gear 52 rotates to drive the driven gear 53, the middle layer plate 2, the guide rod 47, the placing plate 3 and the satellite body to rotate, so as to achieve the purpose of changing the assembly position of the satellite body.

[0046] In order to enable the clamping plate 41 to better fix the satellite body, a fastener 6 for further clamping the satellite body by the clamping plate 41 is also provided on the bottom plate 1. The fastener 6 includes a pulley 61 rotatably connected to the bottom plate 1. The axial direction of the pulley 61 is perpendicular to the length direction of the guide rod 47. The pulley 61 is located below the connecting rod 46. A rope winding wheel 62 is fixedly connected to the upper end surface of the driving gear 52. The rope winding wheel 62 and the driving gear 52 are coaxially arranged. A pull rope 63 is fixedly connected to the lower surface of the connecting rod 46. One end of the pull rope 63 away from the connecting rod 46 is wound around the rope winding wheel 62. The pulley 61 is in contact with the pull rope 63, and the pulley 61 is located above the pull rope 63.

[0047] When the driving gear 52 rotates, the driving gear 52 drives the rope winding wheel 62 to rotate. The rope winding wheel 62 rotates to wind the pull rope 63 around the rope winding wheel 62. While the pull rope 63 is wound around the rope winding wheel 62, it pulls the connecting rod 46 and the guide rod 47 to move downward. The movement of the connecting rod 46 drives the guide rod 47 and the placing plate 3 to move downward. The movement of the connecting rod 46 also drives the hinge rod 45 to rotate. The rotation of the hinge rod 45 drives the mounting block 43, the support rod 42 and the clamping plate 41 to move, so that the two clamping plates 41 move towards each other, and the two clamping plates 41 can better fix the satellite body.

[0048] When it is necessary to drive and remove the satellite main body, while the operator pulls up the satellite main body through the lifting device, the driving motor 51 also needs to be started. The driving motor 51 drives the driving gear 52 and the rope winding wheel 62 to rotate. The rotation of the rope winding wheel 62 releases the pulling rope 63. At this time, the supporting spring 32 resumes deformation and pushes the placing plate 3, the guiding rod 47 and the connecting rod 46 to move upward. At the same time, the reset spring 44 resumes deformation and pulls the mounting block 43, the support rod 42 and the clamping plate 41 to move, so that the two clamping plates 41 move away from each other; when both the supporting spring 32 and the reset spring 44 resume to the natural state, the clamping plate 41 resumes to the initial position. At this time, the driving motor 51 is turned off.

[0049] The implementation principle of the auxiliary device for low-orbit satellite ground assembly in the embodiment of the present application is as follows: when the operator needs to assemble the satellite main body, first place the satellite main body between the two clamping plates 41. The satellite main body presses the placing plate 3 to move downward. The movement of the placing plate 3 drives the guiding rod 47 and the connecting rod 46 to move downward, so that the articulated rod 45 pulls the mounting block 43, the support rod 42 and the clamping plate 41 to move, and the two clamping plates 41 cooperate to fix the satellite main body. The connecting rod 46 moves to lower the pulling rope 63; when it is necessary to rotate the satellite main body, start the driving motor 51. The driving motor 51 drives the driving gear 52 to rotate. The rotation of the driving gear 52 drives the driven gear 53, the middle layer plate 2, the placing plate 3 and the satellite main body to rotate.

[0050] While the driving gear 52 rotates, it drives the rope winding wheel 62 to rotate. The rotation of the rope winding wheel 62 winds the pulling rope 63 onto the rope winding wheel 62. While the pulling rope 63 is wound onto the rope winding wheel 62, it pulls the connecting rod 46 and the guiding rod 47 to continue moving downward, so that the two clamping plates 41 continue to move closer to each other, so that the two clamping plates 41 can further fix the satellite main body. When it is necessary to remove the satellite main body, start the driving motor 51. The driving motor 51 drives the driving gear 52 and the rope winding wheel 62 to rotate. The rotation of the rope winding wheel 62 releases the pulling rope 63. At the same time, the operator pulls the satellite main body upward through the lifting device. While the satellite main body moves, both the supporting spring 32 and the reset spring 44 resume deformation, so that the two clamping plates 41 move away from each other. When both the supporting spring 32 and the reset spring 44 resume to the natural state, the clamping plate 41 resumes to the initial position.

[0051] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
