Description

Technical Field

[0001] The invention relates to the technical field of large-scale mechanical equipment, and in particular to a large-scale, high-rigidity, quickly adjustable assembly device. Background Art

[0002] During the assembly process, large radar radomes (opening length exceeds 10 meters) need to be assembled with the antenna with the help of an assembly device. Since the radome has a simple appearance and does not allow additional mounting holes to be added to the surface of the radome, the assembly device can only use rubber pressure blocks to press the radome in multiple directions, and use the mounting holes at the opening of the radome to complete the assembly process. The assembly process of the radome involves processes such as angle conversion and docking. Multi-degree-of-freedom assembly devices can complete the assembly process, but the cost is high and the flexibility is poor; the assembly device of the hoisting method has a lower cost, but the assembly device deforms greatly during the hoisting process, which can easily cause the radome to deform greatly and affect performance. In addition, the rubber pressure blocks on the current assembly device work independently and are large in number. Only one can be adjusted at a time, so that all the pressure blocks press the radome or loosen the radome for a long time, resulting in low assembly efficiency.

DETAILED DESCRIPTION

[0030] The above and other technical features and advantages of the present invention are described in more detail below in conjunction with the accompanying drawings.

[0031] Example 1

[0032] In this embodiment, if Figure 1 , Figure 5 , Figure 6 , Figure 7 As shown, Figure 1 The structural view of the assembly device is shown below. Figure 5 This is a view of the front upper structure consisting of the adjustment mechanism, connecting rod mechanism, and separation and combination mechanism; Figure 6 This is a view of the middle row upper structure consisting of the adjustment mechanism, connecting rod mechanism, and separation and combination mechanism; Figure 7 The figure is a rear structural view composed of an adjusting mechanism, a connecting rod mechanism, and a separating and combining mechanism; the technical solution adopted by the present invention is to provide a large-scale, high-rigidity, quickly adjustable assembly device, including a frame mechanism 1, multiple adjusting mechanisms 2, multiple connecting rod mechanisms 3, and multiple separating and combining mechanisms 4.

[0033] Each of the connecting rod mechanisms 3 includes a rotating shaft 31, and the rotating shaft 31 is rotatably set on the frame mechanism 1. The multiple adjusting mechanisms 2 and the separation and combination mechanisms 4 are respectively distributed along the length direction of the corresponding rotating shaft 31. The multiple separation and combination mechanisms 4 are arranged in a one-to-one correspondence with the multiple adjusting mechanisms 2. Each of the adjusting mechanisms 2 has two states of coupling and separation with the corresponding rotating shaft 31. The separation and combination mechanism 4 is used for switching between the coupling and separation states, and the multiple separation and combination mechanisms 4 operate synchronously.

[0034] like Figure 2 As shown, Figure 2It is a structural view of the frame mechanism; the frame mechanism 1 includes a frame support member 11, a double-mouthed U-shaped structural member 12, a frame connecting rod 13, a lifting ring 14, a lifting ear 15, and a connecting plate 16. The frame support member 11 has three specifications. The frame support member 11 is a double C-shaped structure, and according to the size, they are a large double C-shaped structural member 111, a medium double C-shaped structural member 112, and a small double C-shaped structural member 113; there are 5 large double C-shaped structural members 111, which are respectively located in the middle position of the main structure of the frame mechanism and are evenly arranged, there are two medium double C-shaped structural members 112 and two small double C-shaped structural members 113, two medium double C-shaped structural members 112 are placed on the outside of the large double C-shaped structural member 111, and two small double C-shaped structural members 113 are placed on the outermost side, all the frame support members 11 have the same opening direction, and multiple frame support members 11 are welded to each other through frame connecting rods 13, and the ends of multiple frame support members 11 are welded in turn to form a frame opening 12.

[0035] There are four lifting rings 14, which are respectively placed on the frame connecting rods 13. When the lifting rings 14 are lifted, the opening of the frame mechanism 1 faces downward. There are four lifting ears 15, which are respectively placed on the frame connecting rods 13. When the lifting ears 15 are lifted, the opening of the frame mechanism 1 is horizontal. The frame mechanism adopts three kinds of frame support members 11 and frame connecting rods 13 welded together, which has a simple structure and high rigidity. The opening deformation of the frame mechanism 1 is small during the lifting process, which has no effect on the performance of the antenna cover, thereby ensuring the assembly quality of the antenna cover.

[0036] like Figure 3 As shown, Figure 3 It is a structural view of the adjustment mechanism; the adjustment mechanism 2 includes an adjusting wheel 21, a screw rod 22, a tubular worm 231, a worm wheel 232, a connecting block 24, a nut pair 25, a support plate 26, a pressure edge 27, an upper pressure block 28, and a lower pressure block 29. The adjusting wheel 21 is placed on the periphery of the screw rod 22 and is connected to the screw rod 22 by a thread. A circular hole is opened in the middle of the upper pressure block 28. One end of the screw rod 22 is unconstrained, and the other end is placed in the circular hole of the upper pressure block 28 and is fixedly connected by side screws. The adjusting wheel 21, the worm wheel 232, and the connecting block 24 are connected in sequence.

[0037] Specifically, the middle part of the adjusting wheel 21 is threadedly connected to the screw rod 22, and the end face of the middle part of the adjusting wheel 21 is provided with four through holes. The flange end face of the connecting block 24 is provided with four through holes and the middle is also a through hole. The whole is placed on the periphery of the screw rod 22 and has no contact with the screw rod 22. The two end faces of the worm wheel 232 are provided with four threaded through holes, one side is connected to the middle part of the adjusting wheel 21, and the other side is connected to the connecting block 24.

[0038] The worm wheel 232 is meshed with the cylindrical worm 231, and the connecting block 24 is embedded in the nut pair 25 and can rotate. The nut pair 25 is fixedly connected to the support plate 26 to constrain the connecting block 24 from moving axially along the screw rod 22. The connecting block 24 connects the adjusting wheel 21 and the worm wheel 232 together to constrain the adjusting wheel 21 and the worm wheel 232 to move axially along the screw rod 22. The nut pair 25 is connected to the screw rod 22 by threads and welded to the support plate 26. There are two support plates 26, both of which are welded to the frame connecting rod 13.

[0039] There are five types of the edge pressing 27, upper pressing block 28 and lower pressing block 29, which have different sizes but similar structures. The edge pressing 27 is placed above the upper pressing block 28, and the lower pressing block 29 is connected to the upper pressing block 28 with glue. The upper pressing block 28 is made of wood, and the lower pressing block 29 is made of rubber. The wood material is relatively light and easy to adjust, while the rubber material is relatively soft and easy to deform. It has a certain buffering effect and is not easy to damage the assembly parts.

[0040] like Figure 1 , Figure 4 As shown, Figure 1 A structural view of the assembly device; Figure 4 It is a partial structural sectional view of the connecting rod mechanism; the connecting rod mechanism 3 includes a rotating shaft 31, a sleeve 32, a positioning bearing 33, a support seat 34, a coupling 35, and a manual wheel 36. The rotating shaft 31 has a similar structure, including a front rotating shaft, a middle rotating shaft and a rear rotating shaft. Multiple rotating shafts 31 are connected by couplings 35, and multiple rotating shafts 31 are supported and fixed by a support seat 34. The cylindrical worm 231 is placed on the periphery of the rotating shaft 31 and is connected to the rotating shaft 31 through two positioning bearings 33. The two positioning bearings 33 are connected to each other. The cylindrical worm 231 is connected by a sleeve 32, one side of the cylindrical worm 231 is positioned by the shoulder of the rotating shaft 31, and the other side is positioned by the sleeve 32. The coupling 35 has two specifications, a diaphragm coupling 35 and a universal coupling 35. The diaphragm coupling 35 serves to connect the two colinear rotating shafts 31, and the universal coupling 35 serves to connect the two rotating shafts 31 with an angle between the axes. There are 5 manual wheels 36, 2 in the front row, arranged up and down, 2 in the middle row, arranged up and down, and 1 in the back row, which are respectively fixed at one end of the rotating shaft 31.

[0041] like Figure 8 , Fig. 9 As shown, Figure 8 It is a structural view of the separation and combination mechanism; Fig. 9It is a view of the assembly connection structure of the adjustment mechanism, the connecting rod mechanism, and the separation and combination mechanism; the separation and combination mechanism 4 includes a sliding core 41, a sliding rod 42, an insert rod 43, a spring 44, and a traction rope 45. The traction rope 45 connects all the sliding cores 41 in the rotating shaft 31 where each manual wheel 36 is located through the connecting hole in the middle of the sliding core 41, and there is a fixing knot at each sliding core 41 for fixing the sliding core 41. One end of the traction rope 45 leaks out of the manual wheel 36. By pulling the traction rope 45, the sliding core 41 can be moved axially along the rotating shaft 31. The sliding core 41 is inside the rotating shaft 31 and can slide in the axial direction. The sliding rods 42 are evenly distributed on the sliding core 41 in groups of three and are placed in the waist-shaped groove of the rotating shaft 31. Movement, a shoulder is provided on the rotating shaft 31, a first positioning through hole is provided on the shoulder, a second positioning through hole is provided on the tubular worm 231, the insertion rod 43 is grouped in groups of 3, one end is fixed on the sliding rod 42, the other end passes through the first positioning through hole on the shoulder, and is inserted into the second positioning through hole on the tubular worm 231, so that the tubular worm 231 and the rotating shaft 31 can rotate together, and then all the tubular worms 231 on the connected rotating shafts 31 can rotate together, the springs 44 are grouped in groups of 3, and are placed on the periphery of the insertion rod 43, and between the tubular worm 231 and the shoulder of the rotating shaft 31, in a compressed state, to keep the insertion rod 43 always inserted in the second positioning through hole of the tubular worm 231 without external force.

[0042] Example 2

[0043] When using, Fig.10 As shown, Fig.10 The structural view of the assembly material antenna cover; the antenna cover is placed on the horizontal platform with its opening facing downwards. At this time, the insertion rod 43 of the separation and combination mechanism 4 on the assembly device is still inserted into the second positioning through hole of the cylindrical worm 231. All the cylindrical worms 231 on the same rotating shaft 31 are in an integral rotation state. The manual wheel 36 is turned, and the rotating shaft 31 rotates accordingly. Under the action of the coupling 35, multiple rotating shafts 31 rotate synchronously, driving the cylindrical worm 231 to rotate. Under the meshing of the cylindrical worm 231 and the worm wheel 232, the adjustment mechanism 2 moves outward toward the frame mechanism 1, and the screw 22 moves upward, that is, moves away from the upper and lower pressure blocks. When the screw 22 moves a certain distance, the manual wheel 36 stops rotating. Under the action of the crane, the assembly device is lifted by the lifting ring 14. At this time, the frame mechanism 1 opens downwards, and the assembly device is placed on the periphery of the antenna cover and connected to the antenna cover through the connecting plate 16.

[0044] Then adjust the rear, middle and front connecting rod mechanisms 2 in turn. When adjusting, turn the manual wheel 36 to move the adjusting mechanism inward toward the frame mechanism 1. After adjusting a certain distance, pull the traction rope 45 near the manual wheel 36 to move the sliding core 41, separate the insertion rod 43 from the hole of the cylindrical worm 231, and fix the traction rope 45 at the manual wheel 36. All the cylindrical worms 231 work independently at this time. Adjust the corresponding adjusting mechanism 2 as needed, turn the adjusting wheel 21, adjust the lower pressing block 29 to the right position, and press the antenna cover. This process realizes independent fine-tuning after adjusting the adjusting mechanism as a whole in a large range, and the adjustment time of the whole process is short.

[0045] When all the pressing blocks 29 are pressed tightly against the antenna cover, the crane lifts the assembly device and turns it 90 degrees (that is, when the opening is horizontal), places the assembly device on the horizontal platform, and then lifts the assembly device horizontally through the lifting lugs to the antenna assembly site. After the antenna cover and the antenna are assembled, the screws of the connecting plate 16 and the antenna cover are removed, and then the traction rope 45 is released. Under the action of the spring 44, the sliding core 41 moves, and the insertion rod 43 is inserted into the hole of the cylindrical worm 231 again. If there is an insertion rod 43 and the cylindrical worm 2 If the hole 31 is not aligned and not inserted, the cylindrical worm gear 231 can be rotated at a small angle manually to assist. After the hole is aligned, the insertion rod 43 can be inserted to make the cylindrical worm gear 231 connected with the rotating shaft 31 in a state of being able to rotate as a whole. Then, the manual wheels 36 of the front, middle and rear rows of the connecting rod mechanism 3 are rotated in turn to move the adjustment mechanism 2 outward toward the frame mechanism 1. After moving a certain distance, the antenna cover assembly position is evacuated under the action of the crane. Finally, the assembly device is placed on the horizontal platform, and the antenna cover assembly process is completed.

[0046] The present invention uses a frame mechanism welded by using three double C-shaped structural parts and frame connecting rods, which has a simple structure and high rigidity. During the lifting process, the opening deformation of the frame mechanism 1 is small, which has no effect on the performance of the antenna cover, thereby ensuring the assembly quality of the antenna cover. The adjustment mechanism 2, the connecting rod mechanism 3 and the separation and combination mechanism 4 are used to enable multiple pressing blocks 29 to work as a whole or individually. During the clamping process, the overall adjustment can be greatly adjusted first and then fine-tuned independently. During the loosening process, the overall adjustment can be greatly adjusted. The adjustment time of the whole process is short, thereby improving the assembly efficiency of the antenna cover.

[0047] The above description is only a preferred embodiment of the present invention, which is only illustrative and not restrictive of the present invention. Those skilled in the art understand that many changes, modifications, and even equivalences may be made to the present invention within the spirit and scope defined by the claims of the present invention, but all of them will fall within the scope of protection of the present invention.
