[0022] Implementation Method 1 Reference Figures 1 to 11 This embodiment, as an optional embodiment of this application, discloses an assembly device for a cargo aircraft crash barrier, including a frame 1. The frame 1 includes a frame 101, a support base 102 and a hanger 103 are provided on the base plate, the support base 102 and the hanger 103 are arranged sequentially along the width direction of the frame 101, the hanger 103 is arranged vertically, and a diagonal brace 105 is also provided between its side and the frame 101 to improve the structural stability and reliability of the hanger 103; The top of the support base 102 is provided with a support block for placing the lower beam; a number of columns 104 are also provided on the top of the support base 102. The assembly device also includes a skin positioning support module 2, which includes a mounting base 201 and a limiting plate 202. The mounting base 201 is connected to the top of the hanger 103 by several connecting bolts. The limiting plate 202 is generally L-shaped, with one end connected to the mounting base 201 and the other end facing the skin as a positioning surface 203. A positioning pin 204 is provided on the positioning surface 203. In use, the positioning pin 204 is inserted into the positioning hole on the skin, and the positioning surface 203 is in contact with the outer surface of the skin to fix the skin. When the skin is changed, different skin positioning support modules 2 can be installed. It should be noted that skin positioning support modules 2 are provided on both the upper and lower sides of the frame 1 to ensure that the skin can be fully positioned. The assembly device also includes an upper beam positioning support module 3, which includes a first upper beam positioner and a second upper beam positioner. The first upper beam positioner includes a first connecting seat 301, which is connected to the hanger 103 by bolts. A transverse positioning surface 302 is also provided on the first connecting seat 301. The second upper beam positioner includes a second connecting seat 303 and a vertical support seat 304 that are connected to each other. The second connecting seat 303 is connected to the lower side of the hanger 103 by bolts. The upper beam of the crash barrier generally exceeds the arc-shaped structure. During installation, one end face of the upper beam abuts against the horizontal positioning surface 302 along the horizontal direction, while the bottom of the upper beam is placed on the vertical support 304, with its bottom end face abutting against the top surface of the vertical support 304. Thus, positioning constraints are formed at both ends of the upper beam, ensuring the accuracy of the installation position and the stability of the installation. Furthermore, a clamping rod 305 is threadedly connected to both the first connecting seat 301 and the second connecting seat 303. A clamping block is provided on the section of the clamping rod 305 facing the upper beam. In use, the clamping rod 305 is rotated to make the clamping block tightly abut against the outer surface of the upper beam, thereby fixing the upper beam, further improving its installation stability, ensuring the safety of assembly, and preventing displacement during assembly, thus improving assembly accuracy.

[0023] Furthermore, the upper beam positioning support rod module also includes a third upper beam positioner, which includes a third connecting seat 306 and a boom 307 that are hinged together; an adjusting rod 308 is threadedly connected to the boom 307, and a U-shaped arm 309 is provided at one end of the adjusting rod 308; a large shaft positioning pin 310 adapted to the upper beam is provided on the U-shaped arm 309. Meanwhile, a locking screw is also provided between the third connecting seat 306 and the boom 307; The third upper beam positioner can be adapted to individual upper beams with special models, and the adjusting rod 308 also has a large adjustable range, thereby meeting different assembly requirements and diverse assembly needs. Secondly, the hinged third connecting seat 306 and the boom 307 can be folded during the hoisting of the upper beam, thereby freeing up the loading space of the entire assembly device, avoiding interference with the upper beam during the loading process, protecting the upper beam, reducing the difficulty of hoisting, and improving assembly efficiency. Furthermore, the assembly device also includes a positioning module 4 and a pressing module 5, wherein the positioning module 4 includes a plurality of positioning plates 401, the positioning plate 401 is generally elongated, and the side of the positioning plate 401 facing the anti-collision wall assembly area is integrally connected with a flange, that is, the cross-section of the positioning plate 401 is L-shaped. Along the length of the positioning plate 401, both ends of the positioning plate 401 are provided with positioning slides 402, and the hanger 103 is provided with two retraction slides 403. In the vertical direction, one end of each of the two retraction slides 403 is offset away from the side of the anti-collision wall assembly area; the two retraction slides 403 are connected to the two positioning slides 402 respectively through sliders. That is, in the vertical direction, the yielding slide rail 403 is inclined, and the specific arrangement is as follows: Figure 1 and 2 ; Since both retraction slide rails 403 are inclined, when the positioning plate 401 is slid, the flange on the side of the positioning plate 401 moves closer to or further away from the anti-collision wall, thereby achieving separation of the positioning plate 401 from the anti-collision wall.

[0024] Furthermore, a locking seat is provided on the retraction slide rail 403, and a locking screw adapted to the locking seat is provided on the positioning plate 401; the positioning plate 401 is fixed at the target position by the cooperation of the locking seat and the locking screw, thereby ensuring the stability of the positioning plate 401, avoiding its slippage during assembly, and ensuring the accuracy and reliability of positioning.

[0025] Furthermore, the clamping module 5 includes a lifting frame 501, which is generally elongated. Lifting slides 502 are provided at both ends of the lifting frame 501 along its length. Two lifting slide rails 503 are provided on the hanger 103, and the two lifting slide rails 503 are slidably connected to the two lifting slides 502 respectively via sliders. The lifting frame 501 also has several adjusting seats 504, each of which is threadedly connected to a longitudinal beam clamping rod 505. The longitudinal beam clamping rod 505 is also provided with clamping blocks adapted to the longitudinal beams of the crash barrier. The lifting frame 501, which slides up and down, can effectively adjust the clamping and fixing points of each longitudinal beam, ensuring that the clamping operation of the longitudinal beam is always performed at the optimal point. Secondly, the threaded longitudinal beam clamping rod 505 can adjust and control the clamping block. On the one hand, it can avoid friction damage between the lifting frame 501 and the longitudinal beam during the adjustment process. On the other hand, it can also meet the clamping and fixing requirements of longitudinal beams of different specifications, and meet diverse assembly needs. By cooperating with the positioning module 4 and the clamping module 5, the positioning and clamping of the crash barrier can be achieved in the middle area, thereby ensuring the stability of the entire crash barrier. Secondly, the clamping in the middle can effectively prevent the deformation of the anti-collision wall caused by external forces during the assembly process, ensuring the accuracy of the anti-collision wall after assembly and improving the assembly quality. Furthermore, the assembly device also includes a lower beam positioning support module 6, which includes a lower connecting seat 601, a horizontal fastening plate 602, and a vertical fastening plate 603. The lower connecting seat 601 is connected to the support seat 102 via several connecting screws. The horizontal fastening plate 602 is hinged to the lower support seat 102, and the vertical fastening plate 603 is hinged to the horizontal fastening plate 602. A fixing screw 604 is provided between the horizontal fastening plate 602 and the lower connecting seat 601. A fixing screw is provided between the vertical fastening plate 603 and the horizontal fastening plate 602. A horizontal locking rod 605 is threadedly connected to the horizontal fastening plate 602, and a vertical locking rod 606 is provided on the vertical fastening plate 603. Both the horizontal locking rod 605 and the vertical locking rod 606 are provided with clamping blocks. The clamping blocks clamp the lower beam from the horizontal and vertical directions respectively to fix the lower beam to the support base 102. Furthermore, along the length direction of the support 102, a limiting seat 7 is provided at one end of the support 102. The limiting seat can limit one end of the lower beam along the length direction, which can improve the installation stability of the lower beam and also enable precise positioning. The other end of the support base 102 is provided with a fourth connecting base 8, and an adjusting plate 9 is hinged to the fourth connecting base 8. An inclined adjusting rod 10 is threadedly connected to the adjusting plate 9. The inclined adjusting rod 10 is inclined relative to the vertical surface of the lower beam, and its bottom end is inserted into the bottom of the lower beam. An inclined clamping block 11 is threadedly connected to the free end of the inclined adjusting rod 10, and the inclined clamping block 11 is in close contact with the side of the lower beam. Meanwhile, an anti-interference groove is also provided on the inclined clamping block 11. In use, the skin is first connected to the respective skin support modules located on the upper and lower sides of the frame to complete the skin clamping; The upper beam is then connected to the upper beam positioning support module, and the upper beam is fixed by the corresponding clamping rod. Then, install each longitudinal beam in sequence on the upper beam, and finally install the lower beam. After the longitudinal beams and lower beam are installed, adjust the position of the positioning module and the clamping module to fix each longitudinal beam. After all the parts are assembled, manual assembly work will then be carried out. Compared with the prior art, this application places bulky components on the assembly device, thereby reducing the labor intensity of workers; at the same time, the assembly device described in this application can also assemble all parts in one go. After the assembly is completed, the workers only need to perform further fixing work, thereby improving assembly efficiency. Meanwhile, the assembly device of this application can also accurately position each component, ensuring the accuracy of the connection between each component. Furthermore, during the assembly process, each component is in a fixed state, which can effectively reduce assembly errors and further improve the assembly accuracy of the crash barrier. Finally, this application modularizes the positioning support devices in different parts, allowing for the adaptation to anti-collision walls of different structures by replacing different modules, thereby meeting diverse assembly needs and improving the applicability of the equipment.
