Description

Technical Field

[0001] The present invention relates to the technical field of satellite electrical performance testing, and in particular to a satellite feed and wave absorbing box on-board testing device and an assembly method. Background Art

[0002] The satellite feed is installed at the end of the deployment mechanism and enters the working state after being deployed in orbit. When working, the feed emits high-power microwaves through the horn. The high-power microwaves reach the target area through the antenna reflection surface to generate echoes. The satellite processes the echoes to generate images. As the main payload of the satellite, the satellite feed needs to simulate the on-orbit working state during the satellite electrical performance test. During the test, high-power microwave radiation will be generated, which will affect the occupational health and safety of surrounding personnel. The high-power microwaves emitted by the satellite feed can be absorbed by the absorbing box, which can greatly reduce the risk of microwave radiation. Therefore, During the satellite electrical performance test, a satellite feed and an absorbing box need to be placed next to the satellite and assembled and positioned to ensure that the microwave radiation is controllable. The satellite feed weighs about 60kg, and the absorbing box weighs about 300kg. The length of the satellite feed head entering the absorbing box is not less than 150mm, and it cannot interfere with the absorbing material inside the absorbing box. This requirement can be achieved with the help of thermal test tooling, but the assembly process of the tooling is complicated, there is no adjustment, and it needs to be repaired on site. The assembly repeatability is poor, and the assembly cannot be flexibly moved, which is inconvenient for daily electrical performance testing and cannot adapt to changes in different test sites.

[0003] Therefore, it is urgent to design a satellite feed and absorber box on-board test device and assembly method. Based on the needs of improving assembly reliability and test site adaptability, a satellite feed and absorber box on-board test device is designed to reliably assemble the satellite feed and absorber box, simulate the electrical performance test in the on-orbit state, and adapt to different test scenarios to ensure the occupational health and safety of personnel.

[0062] A method for assembling a satellite feed and a wave absorbing box near-satellite test device comprises the following steps:

[0063] Step 1: Select a suitable site and use the support mechanism to lift the vehicle body.

[0064] Use the hand wheel to turn the threaded screw, which gradually touches the ground and props up the vehicle body. The propping height should be such that the fixed wheels and universal wheels are off the ground.

[0065] Step 2: Hoist the absorbing box into the accommodation space of the vehicle body and slowly lower it to close to the upper surface of the bottom plate. Position the absorbing box through two sets of L-shaped baffles. The bottom of one set of long sides and one set of short sides of the absorbing box are in full contact with the two sets of L-shaped baffles. Slowly lower the absorbing box to the upper surface of the bottom plate. Then, fix the other two sets of L-shaped baffles on the other two sides to the corresponding positions on the upper surface of the bottom plate and connect and fix them to the other set of long sides and short sides of the absorbing box to define the installation position of the absorbing box.

[0066] Step 3: Assemble the guide assembly by vertically connecting the two sets of positioning pins to a portion of the mounting plate. The assembled guide assembly is then mounted on the beams on both sides of the support frame.

[0067] Step 4: Assemble the feed tooling, fix the two sets of mounting plate parts to the bottom of the crossbar, and symmetrically connect the two sets of first fixing parts to the two sets of mounting plate parts, that is, fix the connecting plate part to the mounting plate part by screws;

[0068] Step 5: Move the assembly of the horizontal bar, vertical bar, mounting plate and first fixing part closer to the satellite feed, and connect the first fixing part and the satellite feed through the second through-hole reserved on the first positioning plate with screws;

[0069] Step 6: symmetrically connect the two sets of second fixing parts to the two sets of mounting plate parts, that is, the second connecting plate part is fixedly connected to the second mounting plate part by screws.

A through hole is provided on the second connecting plate part, and a mounting hole is provided on the second mounting plate part. The mounting hole is a waist-shaped hole. The mounting position is adjusted according to the actual hole position difference on site through the adjustment amount reserved for the mounting hole.

[0070] Step 7: Hoist the feed tooling and satellite feed assembly above the vehicle body, and slowly lower the assembly into the accommodation space above the absorbing box;

[0071] Step 8: Before the lower part of the feed tooling and the satellite feed assembly approaches the upper surface of the absorbing box, align the four sets of positioning pins with the four pin holes of the feed tooling, and slowly lower the assembly. Observe the relative height between the lower part of the satellite feed and the internal structure of the absorbing box. According to the actual situation, add gaskets to the upper surface of the feed tooling and the mounting plate, and put the gaskets on the positioning pins.

[0072] Step 9: Rotate the support mechanism and lower the vehicle body through the support mechanism. In the same way as in step 1, the fixed wheels and universal wheels are lowered to the ground. The support mechanism is no longer in contact with the ground. The device assembly is then transported to the corresponding position of the test station through the traction mechanism.

[0073] Step 10: Rotate the support mechanism after it is in place according to the actual position requirements, with the directional wheels and universal wheels leaving the ground. Ensure that the support mechanism is in reliable contact with the ground and the vehicle body is reliably supported. Connect the feed-related cables and grounding wires as required, and cooperate with the entire satellite electrical performance test.

[0076] 2. The present invention adopts a clearance fit between a longer positioning pin and the pin hole of the crossbar, which solves the problem of collision when the feed tooling and the heavy satellite feed assembly are installed on the vehicle body, and ensures the lateral relative position of the satellite feed and the absorber box;

[0077] 3. The connections between the crossbar and the first and second fixing parts, as well as the connections between the first and second fixing parts and the satellite feed, are designed with waist-shaped holes and an assembly sequence to achieve assembly allowance adjustment, which reduces the precision requirements of the machining process, avoids the risk of connection failure during on-site assembly, and improves assembly reliability.

[0078] 4. Based on the dimensional chain design between the feed tooling and the vehicle body, the height dimensions of the satellite and the absorber box are controlled using gaskets, which improves the flexibility and reliability of on-site assembly and ensures the smooth implementation of the assembly task;

[0079] 5. The present invention installs a baffle assembly on the bottom plate to position the absorbing box laterally, and cooperates with the positioning pins to ensure the limit design requirements between the absorbing box and the satellite feed.

[0108] A satellite feed and absorbing box near-satellite testing device, the device includes a vehicle body 3, a baffle assembly 4, a feed tooling 5, a guide assembly 6, a support mechanism 7, a directional wheel 81, a universal wheel 82 and a traction mechanism 9. The vehicle body 3 has a bottom plate 31 and a support frame 32. The bottom plate 31 is used to support the absorbing box 2. The space enclosed by the support frame 32 is used to accommodate the absorbing box 2 and the satellite feed 1. The satellite feed 1 is assembled above the absorbing box 2, and the distance between the two is adjustable.

[0109] The bottom plate 31 is rectangular, and a baffle assembly 4 is installed on the upper surface of the bottom plate 31. The baffle assembly 4 consists of a plurality of L-shaped baffles 41, wherein an L-shaped baffle 41 is installed on each of the two adjacent sides first, and the L-shaped baffle 41 opens outward. One side wall of the L-shaped baffle 41 is fixed on the bottom plate 31. The absorbing box 2 is hoisted into the interior of the vehicle body 3 and slowly lowered. The two side walls of the absorbing box 2 are aligned with the two groups of L-shaped baffles 41. The two groups of L-shaped baffles 41 are installed on the bottom plate 31 in advance to limit the absorbing box 2 in two directions. After being implemented on the bottom plate 31, the L-shaped baffles 41 on the other two sides are installed. The absorbing box 2 is fixed and positioned by the four groups of L-shaped baffles 41.

[0110] Fixed wheels 81 and universal wheels 82 are respectively installed at the two ends of the bottom of the base plate 31, and supporting mechanisms 7 are installed on the outside of the two sets of long sides of the base plate 31. In the early and late stages of the test process, the vehicle body 3 needs to be propped up away from the ground, and this operation needs to be completed through the supporting mechanism 7. The supporting mechanism 7 has a fixed plate 71, a threaded screw 72, a rotating handwheel 73, and a supporting pad 74. The fixed plate 71 is fixedly connected to both sides of the long side of the base plate 31. The fixed plate 71 is spirally connected to the threaded screw 72. The threaded screw 72 can move up and down the fixed plate 71. A rotating handwheel 73 and a supporting pad 74 are respectively installed at the upper and lower ends of the threaded screw 72. The rotating handwheel 73 is convenient for the operator to hold and rotate, and the supporting pad The block 74 is sleeved on the bottom end of the threaded screw 72 so as to better contact the ground, so that the entire device is stable and does not deviate when it is landed. When the vehicle body 3 needs to be lifted up, the hand wheel 73 is turned to move the threaded screw 72 downward, and the threaded screw 72 gradually moves downward until the support block 74 is supported on the ground. At this time, the position of the fixed wheel 81 and the universal wheel 82 at the bottom of the base plate 31 is checked. When the fixed wheel 81 and the universal wheel 82 leave the ground, it is sufficient. Conversely, when the vehicle body 3 and the assembly assembly need to be transported, the hand wheel 73 is turned to move the threaded screw 72 upward, and the threaded screw 72 gradually moves upward until the support block 74 is away from the ground, and the fixed wheel 81 and the universal wheel 82 at the bottom of the base plate 31 are supported on the ground.

[0111] When the vehicle body 3 and the assembly assembly need to be transported, the traction mechanism 9 needs to be operated. The traction mechanism 9 is respectively connected to the universal wheel 82 and the bottom plate 31. The vehicle body 3 is moved and transported through the cooperation of the fixed wheel 81, the universal wheel 82 and the traction mechanism 9. The traction mechanism 9 has a traction rod 91, a fixed shaft 92 and a fork structure 93. The traction rod 91 is cross-connected with the fixed shaft 92. Two sets of fork structures 93 are connected at both ends of the fixed shaft 92. The fork structure 93 is installed on the universal wheel 82. One end of the traction rod 91 is fixed on the bottom plate 31. The traction rod 91 is pulled and cooperated with the fixed wheel 81 and the universal wheel 82 to move the vehicle body 3. At the same time, the traction rod 91 can control the rotation direction of the universal wheel 82 through the fork structure 93 and the fixed shaft 92.

[0112] The satellite feed 1 is assembled on top of the absorbing box 2, which needs to be completed through the cooperation of the vehicle body 3, the feed tooling 5, and the guide assembly 6. First, the support frame 32 of the vehicle body 3 needs to bear the weight of the feed tooling 5 and the satellite feed 1. At the same time, a guide assembly 6 is set on the support frame 32. The guide assembly 6 is used in conjunction with the feed tooling 5. The guide assembly 6 can limit the falling position of the feed tooling 5 and the satellite feed 1 to avoid collision with the satellite feed 1. At the same time, the guide assembly 6 cooperates with the feed tooling 5 to adjust the relative height of the satellite feed 1 and the internal structure of the absorbing box 2. Specifically, the support The frame 32 has a crossbeam 321 and a vertical beam 322. The vertical beam 322 is perpendicular to the bottom plate 31, and the crossbeam 321 is vertically connected between the vertical beams 322. The crossbeam 321 and the vertical beam 322 are combined to form a solid support frame 32. A mounting plate portion 61 is fixedly connected to the crossbeam 321 at the top end (short side of the bottom plate 31) of two adjacent groups of vertical beams 322. The mounting plate portion 61 is installed along the length direction of the crossbeam 321. Two groups of positioning pins 62 are vertically connected to the mounting plate portion 61. The feed tooling 5 is overlapped on the support frame 32 through the positioning pins 62.

[0113] Furthermore, the feed tooling 5 includes a horizontal bar 51, a vertical bar 52, two mounting plate parts 53, a first fixing part 54 and a second fixing part 55. Pin holes 511 are reserved at both ends of the horizontal bar 51. The pin holes 511 are used to match the positioning pins 62. The distance between the two groups of horizontal bars 51 is adapted to the distance between the two groups of positioning pins 62. During operation, the feed tooling 5 is first assembled, and the horizontal bar 51 and the vertical bar 52 form a rectangular frame structure. The two mounting plate parts 53 are connected on both sides of the lower end of the horizontal bar 51. The first fixing part 54 is installed on each group of the two mounting plate parts 53. The two groups of first fixing parts 54 are symmetrically distributed. Through the first fixing part 54 and one of the satellite feed 1 side, and then connect the second fixing part 55 to the other side of the satellite feed 1. Then, the feed tooling 5 together with the satellite feed 1 is lifted and moved to the top of the absorbing box 2 and gradually dropped downward until the pin hole 511 of the cross bar 51 is inserted into the positioning pin 62 corresponding to the position. Then, the relative height of the satellite feed 1 and the internal structure of the absorbing box 2 is observed. By adding a gasket between the feed tooling 5 and the mounting plate part 61 to raise the height of the feed tooling 5 and the satellite feed 1, the relative height of the satellite feed 1 and the internal structure of the absorbing box 2 is adjusted to an appropriate distance. The added gasket can be sleeved on the positioning pin 62 to facilitate the installation of the gasket and prevent the gasket from falling off easily.

[0114] The first fixing portion 54 and the second fixing portion 55 have similar structures. The first fixing portion 54 includes a connecting rod portion 541, a connecting plate portion 542 and a positioning plate portion 543. The second fixing portion 55 includes a connecting rod portion 551, a connecting plate portion 552 and a positioning plate portion 553. The lengths of the connecting rod portion 541 and the connecting rod portion 551 are different. In specific operation, the first fixing portion 54 and the second fixing portion 55 are connected to the satellite feed 1 in the same manner. First, the first fixing portion 54 is fixed to the mounting plate portion 53, and the connecting plate portion 542 of the first fixing portion 54 is fixed to the mounting plate portion 53. Then, the satellite feed 1 is moved closer to the two groups of first fixing portions 54. The positioning plate portion 543 of the first fixing portion 54 is attached to a side wall of the satellite feed 1, and the connecting plate portion 542 is fixed to the mounting plate portion 53. A through hole portion 544 is defined on the portion 542, a through hole portion 2 545 is defined on the positioning plate portion 1 543, and a mounting hole 531 is defined on the mounting plate portion 2 53. The through hole portion 1 544, the through hole portion 2 545, and the mounting hole 531 are used to cooperate with mounting screws and other fasteners. After the first fixing portion 54 is connected to the satellite feed 1, the second fixing portion 55 is fixedly connected to the other side of the satellite feed 1 using the same method. Specifically, the connecting plate portion 2 552 is fixed to the side of the mounting plate portion 2 53 away from the connecting plate portion 1 542, and the positioning plate portion 2 553 gradually fits on the side wall of the satellite feed 1, and is then connected using fasteners such as screws. Since the mounting hole 531 on the mounting plate portion 2 53 is a waist-shaped hole, the waist-shaped hole has an adjustable space, and the position of the second fixing portion 55 can be appropriately adjusted during installation.

[0115] A method for assembling a satellite feed and a wave absorbing box near-satellite test device comprises the following steps:

[0116] Step 1: Select a suitable site, lift the vehicle body 3 with the support mechanism 7, and use the hand wheel 73 to rotate the threaded screw 72. The threaded screw 72 gradually touches the ground and supports the vehicle body 3. The support height is based on the fixed wheels 81 and the universal wheels 82 leaving the ground.

[0117] Step 2: Hoist the absorbing box 2 into the accommodation space of the vehicle body 3 and slowly lower it to close to the upper surface of the bottom plate 31. Position the absorbing box 2 through the two sets of L-shaped baffles 41. The bottoms of one set of long sides and one set of short sides of the absorbing box 4 are in full contact with the two sets of L-shaped baffles 41. Slowly put the absorbing box 2 on the upper surface of the bottom plate 31. Then, fix the other two sets of L-shaped baffles 41 on the other two sides to the corresponding positions on the upper surface of the bottom plate 31 and connect and fix them to the other set of long sides and short sides of the absorbing box 4 to define the installation position of the absorbing box 2.

[0118] Step 3: Assemble the guide assembly 6 by vertically connecting the two sets of positioning pins 62 to the mounting plate portion 61. Then, install the assembled guide assembly 6 on the beams 321 on both sides of the support frame 32.

[0119] Step 4: Assemble the feed tooling 5, fix the two sets of mounting plate parts 53 to the bottom of the crossbar 51, and symmetrically connect the two sets of first fixing parts 54 to the two sets of mounting plate parts 53, that is, fix the connecting plate part 542 to the mounting plate part 53 by screws;

[0120] Step 5: Move the assembly of the horizontal bar 51, vertical bar 52, second mounting plate portion 53, and first fixing portion 54 closer to the satellite feed 1. Use screws to connect the first fixing portion 54 to the satellite feed 1 through the second through-hole portion 545 reserved on the first positioning plate portion 543.

[0121] Step 6: symmetrically connect the two sets of second fixing parts 55 to the two sets of second mounting plate parts 53, that is, the second connecting plate part 552 is fixedly connected to the second mounting plate part 53 by screws. The second positioning plate part 553 of the second fixing part 55 is connected and fixed to the satellite feed source 1 in the same way as in step 5. A through hole 544 is provided on the second connecting plate part 552, and a mounting hole 531 is provided on the second mounting plate part 53. The mounting hole 531 is a waist-shaped hole. The mounting position is adjusted according to the actual hole position difference on site through the adjustment amount reserved for the mounting hole 531.

[0122] Step 7: Hoist the feed tooling 5 and the satellite feed source 1 assembly above the vehicle body 3, and slowly lower the assembly into the accommodation space above the absorbing box 2;

[0123] Step eight: Before the lower part of the feed tooling 5 and the satellite feed source 1 assembly approaches the upper surface of the absorbing box 2, align the four sets of positioning pins 62 with the four pin holes 511 of the feed tooling 5, and slowly lower the assembly. Observe the relative height between the lower part of the satellite feed source 1 and the internal structure of the absorbing box 2. According to the actual situation, add a gasket to the upper surface of the feed tooling 5 and the mounting plate 61, and put the gasket on the positioning pin 62.

[0124] Step 9: Rotate the support mechanism 7 and lower the vehicle body 3 via the support mechanism 7. As in step 1, lower the fixed wheels 81 and the universal wheels 82 to the ground. The support mechanism 7 is no longer in contact with the ground. The device assembly is then transported to the corresponding position of the test station via the traction mechanism 9.

[0125] Step 10: According to the actual position requirements, rotate the support mechanism 7 after it is in place, with the directional wheels 81 and universal wheels 82 leaving the ground. Make sure that the support mechanism 7 is in reliable contact with the ground, and the vehicle body 3 is reliably supported. Connect the feed-related cables and grounding wires as required, and cooperate with the entire satellite electrical performance test.

[0126] The working principle of the above scheme is:

[0127] 1) The second mounting plate portion 53 of the feed fixture 5 has an interface with the first fixing portion 54 and the second fixing portion 55. The waist-shaped hole (mounting hole 531) enables fine adjustment of the first fixing portion 54 and the second fixing portion 55 in the length direction of the second mounting plate portion 53. The first fixing portion 54 and the second fixing portion 55 have mounting interfaces with the side panel of the satellite feed 1. The first positioning plate portion 543 and the second positioning plate portion 553 enable reliable assembly of the first fixing portion 54 and the second fixing portion 55 with the satellite feed 1.

[0128] 2) The absorbing box 2 is hoisted into the interior of the vehicle body 3. Two sets of L-shaped baffles 41 are pre-installed on the bottom plate 31 to limit the position in two directions. The absorbing box 2 is slowly lowered and aligned with the two sets of L-shaped baffles 41. After it is landed on the bottom plate 31, the L-shaped baffles 41 on the other two sides are installed. The absorbing box 2 is securely fixed and positioned by the four sets of L-shaped baffles 41.

[0129] 3) The feed fixture 5 and the satellite feed 1 assembly are hoisted above the vehicle body 3. Pin holes 511 are designed at both ends of the crossbar 51. The pin holes 511 are aligned with the positioning pins 62, and the vehicle is slowly lowered. The relative position of the satellite feed 1 body and the absorbing material in the absorbing box 2 is observed on site. If necessary, a gasket can be added between the feed fixture 5 and the mounting plate portion 61 to avoid interference during the assembly process.

[0130] 4) The traction rod 91 controls the steering of the universal wheel 82 through the wheel fork structure 93 and the fixed shaft 92. The two sets of fixed wheels 81, the two sets of universal wheels 82, and the traction mechanism 9 enable the vehicle body 3 to move;

[0131] 5) When the satellite feed 1 participates in the satellite electrical performance test, by shaking the handwheel 73 of the four sets of support mechanisms 7, the support pad 74 at the bottom of the threaded screw 72 is fully in contact with the ground, and the assembly is reliably supported.

[0132] Finally, it should be noted that the above is a preferred embodiment of the present invention. It should be noted that although the preferred embodiment of the present invention has been described, it is clear that those skilled in the art, once they understand the basic inventive concept of the present invention, can make various improvements and modifications without departing from the principles of the present invention.
