Description

Technical Field

[0001] This utility model relates to the field of aerospace measurement and control technology. More specifically, this utility model relates to a three-dimensional positioning feed source calibration beacon bracket. Background Technology

[0002] In the phase calibration operation of marine telemetry equipment feeders in the aerospace telemetry and control field, beacons need to be precisely fixed at a specific spatial position above the feeder. Current technology uses manual hand-held beacon fixing, which has inherent drawbacks: manual operation makes precise control of spatial coordinates difficult, and beacon positioning is easily affected by the operator's limb stability, leading to random shifts in the fixed position. Especially under ship swaying conditions, the spatial coordinate deviation of the beacon will further increase; the feeder itself lacks a pre-set fixing interface or support structure, requiring the operator to fix the beacon by hand, making it difficult to maintain positional stability.

[0003] Due to the lack of a three-dimensional positioning reference and mechanical constraints, the beacon exhibits uncontrollable offsets in height (Z-axis), horizontal plane angle (rotation direction), and planar coordinates (X / Y direction), ultimately resulting in a feed phase correction error on the order of 10~20°.

[0004] The technical challenge of this problem lies in designing a non-invasive support system that achieves millimeter-level three-dimensional spatial positioning accuracy for the beacon without modifying the feed source structure, while effectively suppressing stability issues caused by vibrations in the marine environment.

[0029] like Figure 1 As shown, this utility model provides a three-dimensional positioning feed source calibration beacon bracket, comprising:

[0030] The fixing part includes a base frame 1 and multiple vertical pillars 2 vertically mounted on the base frame 1. Each vertical pillar 2 has a vertical guide rail 3 vertically mounted on its top. Specifically, the fixing part includes a rectangular base frame 1 and four vertical triangular prism pillars 2. The inner side of the pillar 2 is an inclined surface with an angle between 30 and 45° to fit against the outer wall of the feed column. Each pillar 2 has a vertical guide rail 3 mounted on its top. The vertical guide rail 3 can be made of hard aluminum alloy and can have millimeter-level vertical scale lines on its surface. The length of the vertical guide rail 3 can be selected from 800 to 1200 mm as needed. It is fixed to the top of the pillar 2 by welding. The base frame 1 can be formed by welding stainless steel square tubes. Expansion bolt mounting holes can be set at the four corners of the base frame 1 for fixing to the deck surface.

[0031] Multiple connectors 4 are vertically slidably mounted on multiple vertical guide rails 3. The connectors 4 are horizontally positioned, with one end movably sleeved on the vertical guide rail 3 and the other end horizontally recessed with a clamping groove. The connectors 4 are fixed to the vertical guide rails 3 by a first limiting member. Specifically, the inner diameter of the vertical through hole is 0.5 mm larger than the outer diameter of the vertical guide rail 3 to achieve a clearance fit. The other end is machined with a U-shaped clamping groove with a depth of 20 mm. The first limiting member includes connecting plates symmetrically arranged on both sides of the through hole. The connecting plates have limiting holes with a diameter of 8 mm. During installation, the connectors 4 are sleeved into the vertical guide rails 3 and fastened with M8 bolts through the limiting holes on both sides to achieve height positioning. The height adjustment range covers 0 to 1000 mm.

[0032] The rotating ring 6 is horizontally positioned and is movably embedded in the clamping grooves of multiple connectors 4, and is fixed to the clamping grooves by a second limiting member. Specifically, the rotating ring 6 can be made of aluminum alloy with a diameter of 600 mm. The rotating ring 6 is embedded in the clamping grooves of four connectors 4. The second limiting member includes a connecting plate set on the upper and lower surfaces of the clamping groove. The connecting plate has a limiting hole with a diameter of 6 mm. The rotating ring 6 is pressed and fixed by M6 bolts passing through the limiting hole. The outer circumference of the rotating ring 6 is engraved with a 360° scale. The angle positioning accuracy error does not exceed 0.5 degrees. During operation, the bolts are first loosened to adjust the ring to the target angle position, and then the bolts are tightened to complete the fixation.

[0033] The beacon clamping structure includes two horizontal guide rails 7 parallel to each other and horizontally arranged on a rotating ring 6, and beacon clamps 8 slidably arranged on the two horizontal guide rails 7 on both sides. The beacon clamps 8 have a beacon clamping hole 9 in the center. Specifically, the two parallel horizontal guide rails 7 are welded and installed on the rotating ring 6. The distance between the two parallel horizontal guide rails 7 can be maintained at 150 mm. The surface of the horizontal guide rails 7 can be set with millimeter-level horizontal scale. The beacon clamping structure includes a pair of opposing beacon clamping plates. The inner side of the beacon clamping plates is machined with a semi-circular groove, which is combined to form a beacon clamping hole 9 with a diameter of 50 mm for clamping the beacon. The two ends of the beacon clamping plates are connected and fixed by connecting plates and M5 bolts. When installing the beacon, it is inserted into the beacon clamping hole 9, and the bolts are tightened to make the groove grip the beacon shell. The horizontal travel can be adjusted from 0 to 500 mm.

[0034] In the above technical solution, the base frame 1 is first fixed on the deck around the feed, the height of the connector 4 is adjusted so that the rotating ring 6 reaches the target height position, the fixing bolt of the rotating ring 6 is loosened, rotated to the predetermined angle and then re-locked, the beacon clamp 8 is moved along the horizontal guide rail 7 to the target plane coordinates, and the beacon is fixed through the clamping hole. The above structure realizes three-dimensional precise positioning within a space of 500 mm × 500 mm × 1000 mm above the feed, effectively controls the position offset, eliminates random positioning deviation caused by manual holding, reduces the phase correction error of the Ka band feed from more than 10° to less than 3°, reduces the risk of high-altitude operation at sea, and does not require modification of the feed body structure.

[0035] In another technical solution, one end of the connector 4 is provided with a vertical through hole, and the vertical through hole is fitted onto the vertical guide rail 3 with a gap.

[0036] The first limiting component includes a first groove formed on the side wall of the vertical through hole, and first connecting plates 5 correspondingly protruding on the left and right sides of the first groove. First limiting holes are formed on the first connecting plates 5, and the pair of first limiting holes on the first connecting plates 5 are fixed by bolts and nuts. Specifically, the material of the connecting component 4 can be Q235B carbon structural steel or 6061 aluminum alloy. The axial length of the vertical through hole can be selected as 30~50 mm to ensure the contact area with the vertical guide rail 3. The first groove is formed in the middle of the side wall of the vertical through hole, with a groove depth of 3~5 mm. The two sides of the first groove are symmetrically welded. Connect the first connecting plate 5, which is 6-8 mm thick. The diameter of the first limiting hole on the first connecting plate 5 can be selected as 8-12 mm. The center of the first limiting hole is about 10 mm away from the edge of the first groove. When adjusting the height, first loosen the bolts so that the connecting piece 4 slides vertically along the vertical guide rail 3. After moving to the target height, adjust the torque wrench to the set position and tighten the bolts. The radial pressure generated by the bolts causes the first connecting plate 5 to undergo elastic deformation. The side wall of the first groove and the surface of the vertical guide rail 3 form a surface contact and fixation, so as to limit and fix the connecting piece 4 and adjust the height of the rotating ring 6.

[0037] In another technical solution, the second limiting member includes second connecting plates correspondingly protruding from the upper and lower sides of the clamping ring groove. Second limiting holes are formed on the second connecting plates, and the pair of second limiting holes on the second connecting plates are fixed by bolts and nuts. Specifically, the second connecting plates are vertically protruding from the upper and lower surfaces of the clamping ring groove, with a protrusion height of 5-8 mm and a thickness of 4-6 mm. The material of the second connecting plates can be Q235B carbon steel or 6061 aluminum alloy, and the surface is treated with anti-rust oxidation. During assembly, the rotating ring 6 is embedded into the clamping ring groove of the connecting member 4, so that the second connecting... The connecting plates are located on the upper and lower sides of the rotating ring 6. The bolts are passed through the second limiting holes of the upper and lower second connecting plates in sequence. After screwing in the nuts, they are initially pre-tightened. After adjusting the rotating ring 6 to the target angle, the nuts are tightened with a torque wrench. The axial tension of the bolts causes the upper and lower connecting plates to undergo elastic deformation, pressing the surface of the rotating ring 6 to fix the angle. The rotating ring 6 can be released by reversing the operation during disassembly. The setting of the second limiting component provides stable mechanical constraint and suppresses the angular deviation of the rotating ring 6 caused by the swaying of the ship. At the same time, the re-disassembly design facilitates maintenance and component replacement.

[0038] In another technical solution, the beacon clip 8 includes a pair of clipping plates. A clipping groove is recessed on one side of each clipping plate, forming a clipping hole 9. A third connecting plate 10 protrudes from both ends of the clipping plates. A third limiting hole is provided on the third connecting plate 10. The third limiting holes on the pair of third connecting plates 10 located at the same end are fixed by bolts and nuts. Specifically, the clipping plates can be made of 6061 aluminum alloy plate or Q235B steel plate with a thickness of 5-8mm. The clipping groove is a semi-circular groove with a depth of 3-5mm. The third connecting plate 10 is integral with the clipping plate. The beacon is formed with a protrusion height of 8-12mm and a thickness of 4-6mm. The beacon slots of the two beacon clamping plates are placed opposite each other, so that the beacon is placed in the formed beacon clamping hole 9. The bolts are passed through the third limiting holes of the two third connecting plates 10 at the same end in sequence. After screwing in the nuts, they are manually pre-tightened. Tightening the nuts makes the beacon slots evenly hug the beacon shell. When disassembling, the beacon can be released by loosening the nuts in the opposite direction. The beacon's spatial position is fixed by mechanical constraint, which effectively controls the beacon offset caused by ship rolling. The detachable connection of the beacon clamp 8 facilitates beacon replacement and maintenance, while reducing the risk of high-altitude operations.

[0039] In another technical solution, a vertically mounted label-clamping post 11 is provided on one of the label-clamping plates, and a horizontally mounted label-clamping component 12 is provided on the label-clamping post 11. A reinforcing label clip 13 is provided on the side of the label-clamping component 12 facing the center of the label-clamping hole 9. Specifically, the label-clamping post 11 can be a solid cylinder with a diameter of 8-12mm and a height of 50-80mm, and the material can be 6061 aluminum alloy or 304 stainless steel. The label-clamping component 12 can be a rectangular plate with a length of 30-50mm, a width of 15-20mm, and a thickness of 3-5mm. The top of the beacon post 11 is vertically connected to the beacon by M4-M6 fastening screws. The interior of the reinforcing beacon clip 13 may be equipped with a rubber or polyurethane pad with a Shore hardness of 60A-70A and a thickness of 2-3mm. It is bonded to the inner surface of the reinforcing beacon clip 13 with epoxy resin. The upper part of the beacon can be reinforced by the reinforcing beacon clip 13. The structure of the reinforcing beacon clip 13 is similar to that of the second limiting member. The reinforcing beacon clip 13 provides adjustable auxiliary clamping force and forms a bidirectional constraint with the beacon clip plate to reinforce the upper part of the beacon.

[0040] In another technical solution, the vertical guide rail 3 has vertical graduations along its axial direction, at least one horizontal guide rail 7 has horizontal graduations along its axial direction, and the outer circumferential wall of the rotating ring 6 has rotation angle graduations along its circumference. Specifically, the vertical graduation lines are distributed along the length of the vertical guide rail 3, with graduation intervals of 1 mm or 0.5 mm, and the total graduation range covers 0~1200 mm. The graduation intervals of the horizontal guide rail 7 can also be 1 mm or 0.5 mm, with a single guide rail graduation range of 0~600 mm. The rotation angle graduations are in 5° or 1° increments and are distributed along the 360° circumference of the outer circumference of the rotating ring 6. The scale can be made using laser etching with an etching depth of 0.1~0.3mm. The surface can be filled with black epoxy resin to enhance contrast. The vertical scale line is located in the visible area on the front of the vertical guide rail 3, the horizontal scale line is located at the center line of the upper surface of the horizontal guide rail 7, and the rotation angle scale is located in the 3mm wide annular band in the middle of the outer circumference of the rotating ring 6. During positioning, the operator directly reads the vertical scale value to adjust the height, moves the beacon clip 8 with reference to the horizontal scale, and rotates the positioning rotating ring 6 according to the rotation angle scale. The three scale systems constitute a complete spatial coordinate reference base, realizing three-dimensional precise positioning without auxiliary measuring tools.

[0041] In another technical solution, the number of vertical support columns 2 is four, and the base frame 1 is rectangular; specifically, the number of vertical support columns 2 is fixed at four, located at the four corners of the base frame 1 respectively, and the four vertical support columns 2 are vertically welded to the four corners of the rectangular base frame 1. The rectangular layout of the four vertical support columns 2 and the base frame 1 forms a stable spatial support structure, effectively dispersing the dynamic load in the marine environment.

[0042] In another technical solution, the vertical support 2 is a vertically set triangular prism. The inner surface of the triangular prism in contact with the feed column is a slope, and the inclination angle of the slope ranges from 30° to 45°. Specifically, the cross-section of the vertical support 2 is an equilateral triangle, and the inner surface in contact with the feed column is processed into a slope. The surface of the slope can be processed with anti-slip textures with a depth of 1-2mm. A rubber pad with a thickness of 2-3mm can be applied to the slope area. The slopes of the four triangular prisms are oriented towards the inner center of the base frame 1. By adjusting the position of the base frame 1, the slopes of the four supports are simultaneously attached to the outer circumferential surface of the feed column. The 30°-45° slope angle optimizes the contact mechanical distribution between the vertical support 2 and the feed column, avoiding stress concentration caused by point contact. The line contact mode enhances the resistance to ship roll. Reliable fixing can be achieved without damaging the feed column body, meeting the requirements of non-intrusive installation.
