Description

Technical Field

[0001] This utility model relates to the field of aircraft processing and manufacturing equipment technology, and more specifically to a bottom mounting support tool for transporting aircraft fuselages. Background Technology

[0002] During transportation, the existing aircraft fuselage is generally placed on a corresponding tooling base, and its lower support bracket presses against the corresponding side support block to achieve support;

[0003] However, the existing side support blocks only serve as supports and do not have a structure that can limit the movement of the aircraft fuselage. This means that when the fuselage is placed, if it shifts to the left or right, there is a high probability that it will slip off the corresponding side support block, affecting the placement effect.

[0004] Secondly, all components on the existing tooling base are fixed by welding. However, some aircraft fuselages have certain deviations during manufacturing. When placing them, there is a chance that they will not be inserted into the grooves on the corresponding support plates, which will affect the placement and handling of the aircraft fuselage and result in poor performance. The only solution is to cut off the welded parts of the corresponding components and re-weld and install new corresponding parts, which is very troublesome. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a bottom mounting support fixture for transporting aircraft fuselages. Its left and right side support blocks can be moved relative to each other or away as needed, and the aircraft fuselage can be side-positioned by the outer limiting protrusion positioning part, so that it is not easy to fall off after placement. At the same time, its side support blocks, top fixing plate and front support plate are all fixed by bolts, so that they can be disassembled and replaced as needed. The front support groove or lower groove on the top surface of the corresponding top fixing plate and front support plate can be inserted into the corresponding position of the fuselage to be placed, ensuring the placement effect.

[0006] The solution of this utility model to the aforementioned technical problem is:

[0007] A bottom mounting support fixture for transporting aircraft fuselage includes a bottom horizontal support frame welded and fixed by multiple long rods. A front vertical column is fixed to the middle of the top surface of the front transverse beam of the bottom horizontal support frame. A front support plate is fixed to the top of the front vertical column. A front support groove is formed in the middle of the top surface of the front support plate. The front landing gear mounting shaft of the aircraft fuselage is inserted into the front support groove, and its bottom surface presses against the bottom wall surface of the front support groove.

[0008] Multiple intermediate support frames are fixed in the middle of the bottom horizontal support frame. Side support blocks are installed on the upper part of the left and right sides of the intermediate support frames. Two support brackets on the left and right sides of the aircraft fuselage press against the top surface of the corresponding side support blocks.

[0009] The rear of the bottom horizontal support frame is fixed with multiple rear support frames. The bottom of the rear of the aircraft fuselage is inserted into a lower groove formed in the middle of the top surface of the top fixing plate of the rear support frame, and the outer wall surface of the bottom of the rear of the aircraft fuselage presses against the inner wall surface of the lower groove.

[0010] The bottom horizontal support frame includes a middle horizontal support frame, a front horizontal support frame extending forward is fixed to the top surface of the front part of the middle horizontal support frame, and a rear horizontal support frame extending backward is fixed to the top surface of the rear part of the middle horizontal support frame.

[0011] Two intermediate support frames are installed in the middle of the intermediate horizontal support frame;

[0012] The intermediate support frame includes two vertical columns corresponding to the left and right sides. The bottom ends of the vertical columns are welded and fixed to the top surfaces of the left and right beams of the intermediate horizontal support frame. End fixing connection plates are welded and fixed to the front and rear walls of the top of the two vertical columns. The left and right ends of the intermediate horizontal beam are located between the upper parts of the corresponding two end fixing connection plates and are fixed to the corresponding end fixing connection plates.

[0013] The middle of the top plate and bottom plate at both ends of the middle transverse beam are formed with adjustment slots. Self-lubricating layers are fixed on the front and rear inner sidewalls of the adjustment slots. The adjustment fixing seat is fixed on the outer end face of the corresponding two end fixing connecting plates. The outer end of the self-lubricating layer extends out of the end fixing connecting plate and into the adjustment fixing seat. Its outer side wall is in close contact with the inner side wall of the corresponding side plate of the adjustment fixing seat.

[0014] The front and rear inner sidewalls of the adjusting groove and the corresponding positions of the self-lubricating layer are formed with through holes running through the front and rear. The lower part of the side support block is inserted into the adjusting groove and is located between the two self-lubricating layers. The lower part of the side support block is formed with multiple adjusting waist-shaped grooves. The side support block is installed on the two end fixed connecting plates by bolts, and the screw part of the bolt is inserted into the corresponding adjusting waist-shaped groove.

[0015] The outer end plate of the adjusting fixing seat has a threaded through hole formed in the middle. The screw part of the outer adjusting bolt is screwed into the threaded through hole in the middle of the outer end plate. The inner end of the screw part of the outer adjusting bolt extends out of the inner end face of the outer end plate and is movably connected to the adjusting pressure plate. The adjusting pressure plate presses against the lower part of the side wall at the outer side of the corresponding side support block.

[0016] A fixing plate is fixed in the middle transverse beam at the inner end of the adjusting channel. A sleeve is formed in the middle of the outer end face of the fixing plate. The return spring is located in the adjusting channel, with one end fixed to the end face of the corresponding fixing plate and the other end fixed to the return plate. The return plate presses against the inner wall of the corresponding side support block.

[0017] The outstanding effect of this utility model is:

[0018] Its left and right side support blocks can be moved relative to each other or away as needed, and the aircraft fuselage can be side-positioned by the external limit protrusion positioning part, so that it is not easy to fall off after placement. At the same time, its side support blocks, top fixing plate and front support plate are all fixed by bolts, so that they can be disassembled and replaced as needed. The front support groove or lower groove on the top surface of the corresponding top fixing plate and front support plate can be inserted into the corresponding position of the fuselage to be placed, ensuring the placement effect.

[0025] For example, see below. Figures 1 to 6 As shown, a bottom mounting support fixture for transporting an aircraft fuselage includes a bottom horizontal support frame 10 welded and fixed by multiple long rods. The bottom horizontal support frame 10 includes a middle horizontal support frame 14. A front horizontal support frame 15 extending forward is fixed to the top surface of the front part of the middle horizontal support frame 14, and a rear horizontal support frame 16 extending backward is fixed to the top surface of the rear part of the middle horizontal support frame 14.

[0026] A front vertical column 11 is fixed to the middle of the top surface of the front horizontal beam of the front horizontal support frame 15 of the bottom horizontal support frame 10. The top of the front vertical column 11 is fixedly connected to the front support plate 12 by multiple bolts. A front support groove 13 is formed in the middle of the top surface of the front support plate 12. The front landing gear mounting shaft of the aircraft fuselage 100 is inserted into the front support groove 13, and its bottom surface presses against the bottom wall surface of the front support groove 13.

[0027] The middle of the middle horizontal support frame 14 of the bottom horizontal support frame 10 is fixed with multiple intermediate support frames 20. Side support blocks 30 are installed on the upper part of the left and right sides of the intermediate support frame 20. The two support brackets 101 of the left and right sides of the aircraft fuselage 100 press against the top surface of the corresponding multiple side support blocks 30.

[0028] The rear of the rear horizontal support frame 16 of the bottom horizontal support frame 10 is fixed with a plurality of rear support frames 40. The bottom of the rear part of the aircraft fuselage 100 is inserted into the lower groove formed in the middle of the top surface of the top fixing plate 41 of the rear support frame 40, and the outer wall surface of the bottom of the rear part of the aircraft fuselage 100 is pressed against the inner wall surface of the lower groove.

[0029] Furthermore, the intermediate support frame 20 includes two vertical columns corresponding to the left and right sides. The bottom ends of the vertical columns are welded and fixed to the top surfaces of the left and right side beams of the intermediate horizontal support frame 14. End fixing connection plates 21 are welded and fixed to the front and rear wall surfaces of the top of the two vertical columns. The left and right ends of the intermediate transverse beam 22 are located between the upper parts of the corresponding two end fixing connection plates 21 and are fixed to the corresponding end fixing connection plates 21.

[0030] The middle transverse beam 22 (which is made of hollow profile) has an adjustment groove 23 formed in the middle of the top plate and bottom plate at both ends. A self-lubricating layer 24 is fixed on the inner side wall of the front and rear sides of the adjustment groove 23. The adjustment fixing seat 25 is fixed on the outer end face of the corresponding two end fixing connecting plates 21. The outer end of the self-lubricating layer 24 extends out of the end fixing connecting plate 21 and into the adjustment fixing seat 25. Its outer side wall is close to the inner side wall of the corresponding side plate of the adjustment fixing seat 25.

[0031] The front and rear inner walls of the adjusting groove 23 and the corresponding positions of the self-lubricating layer 24 are formed with through holes extending from front to back. The lower part of the side support block 30 is inserted into the adjusting groove 23 and is located between the two self-lubricating layers 24. The lower part of the side support block 30 is formed with multiple adjusting waist-shaped grooves 31. The side support block 30 is installed on the two end fixed connecting plates 21 by bolts. The bolt thread is inserted into the corresponding adjusting waist-shaped groove 31 and through hole.

[0032] The outer end plate of the adjusting fixing seat 25 has a threaded through hole formed in the middle. The screw part of the outer adjusting bolt 26 is screwed into the threaded through hole in the middle of the outer end plate. The inner end of the screw part of the outer adjusting bolt 26 extends out of the inner end face of the outer end plate and is movably connected to the adjusting pressure plate 27. The adjusting pressure plate 27 presses against the lower part of the side wall on the outer side of the corresponding side support block 30.

[0033] An anti-slip layer 271 is fixed on the end face of the adjusting pressure plate 27, which presses against the lower part of the side wall on the outer side of the corresponding side support block 30.

[0034] A fixing plate is fixed in the middle transverse beam 22 at the inner end of the adjusting channel 23. A sleeve part is formed in the middle of the outer end face of the fixing plate. The return spring 28 is located in the adjusting channel 23. One end of the spring is fixed to the end face of the corresponding fixing plate, and the other end is fixed to the return plate 29. The return plate 29 is pressed against the wall surface of the inner side of the corresponding side support block 30. One end of the return spring 28 is inserted into the corresponding sleeve part.

[0035] A spring 2 is inserted into the threaded portion of the external adjusting bolt 26. One end of the spring 2 applies force to the inner end face of the corresponding outer end plate, and the other end applies force to the corresponding end face of the adjusting pressure plate 27. This spring 2 makes it difficult for the external adjusting bolt 26 to loosen or rotate again after the adjustment is completed. Of course, in order to ensure that the adjustment is in place, a locking nut can be screwed onto the threaded portion of the external adjusting bolt 26 to achieve further locking and fixation.

[0036] Furthermore, the top surface of the outer end of the side support block 30 is formed with an outer limiting protrusion positioning part 32.

[0037] Two rear support frames 40 are fixed to the rear top surface of the rear horizontal support frame 16, and a top fixing plate 41 is fixedly connected to the upper transverse beam of the rear support frame 40 by bolts.

[0038] The top surfaces of the front and rear of the intermediate horizontal support frame 14 are fixed with bottom support beams 3 extending to the left and right. The top surface of the bottom support beam 3 is formed with a downwardly extending groove. The bottom of the horizontal stabilizing support plate 4 is inserted into the corresponding groove, and its outer wall surface is pressed against the inner wall surface of the corresponding groove.

[0039] The horizontal stabilizer support plate 4 is used to place the horizontal tail fin components.

[0040] In this embodiment, the front support plate 12, the side support block 30, the top fixing plate 41 and the bottom support beam 3 are all composite plates, and their hardness is lower than that of the aircraft fuselage, so as to ensure that the aircraft fuselage will not be damaged when placed.

[0041] In this embodiment, the front landing gear mounting shaft of the aircraft fuselage 100 is inserted into the front support groove 13, with its bottom surface pressing against the bottom wall of the front support groove 13. The two support brackets 101 on the left and right sides of the aircraft fuselage 100 press against the top surface of the corresponding side support blocks 30. The bottom of the rear part of the aircraft fuselage 100 is inserted into the lower groove formed in the middle of the top surface of the top fixing plate 41 of the rear support frame 40. The outer wall surface of the bottom of the rear part of the aircraft fuselage 100 presses against the inner wall surface of the lower groove, thus achieving support and placement. Then, by rotating the outer adjusting bolt 26, the two corresponding side support blocks 30 on the left and right sides move relative to each other, so that the outer sides of the two support brackets 101 of the aircraft fuselage 100 rest against the corresponding outer limit protrusion positioning part 32, thus achieving positioning and ensuring that the aircraft fuselage 100 is placed stably. It is easy to adjust and has a good placement effect.

[0042] Meanwhile, in this embodiment, the front support plate 12, side support block 30, and top fixing plate 41 are all bolted and can be disassembled and replaced as needed. Since the shape of the bottom placement position of different aircraft fuselages 100 may vary, the landing gear mounting shaft may not be able to be inserted into the front support groove 13, or the bottom of the rear of the aircraft fuselage 100 may not be able to be inserted into the corresponding lower groove. In such cases, it is only necessary to disassemble the front support plate 12 and the top fixing plate 41, replace them with new front support plates 12 and top fixing plates 41, and process the front support groove 13 and lower groove on their top surfaces to match the shape and structure of the placement position of the aircraft fuselage 100, and then install them for placement. This is very convenient.

[0043] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
