[0033] like Figure 1As shown, the fixed load-bearing device 1 includes a square steel column 11, an angle steel 12, a cross beam 13, a fixed beam 14, a limit support beam 15, a mounting bracket 16, and a mounting beam 17; a mounting seat is arranged at the bottom end of the square steel column 11 and fixedly connected to the ground platform, a cross beam 13 is welded to the top of the square steel column, and the angle steel 12 is used to weld and reinforce the two at a certain angle; the fixed beam 14 is welded and fixed to the top of the cross beam, and four limit support beams 15 are welded between the two fixed beams, and the layout position of the support limit beams is arranged according to the assembly position layout of the two pods; the mounting bracket 16 is welded below the support limit beam, and two mounting beams 17 are welded and fixed to the mounting bracket. The design of the entire device can not only ensure that the structure is stable and reliable and can bear lateral loads, but also meet the mounting requirements of multiple pods.

[0034] like Figure 2 As shown, the hanging and dragging device 2 includes a dragging platform 21, a hanging platform 22, a support and positioning rod 23, a linear bearing 24, a support assembly 25, a balance adjustment assembly 26, a connecting ear piece 27, a ball screw assembly 28, a mounting seat 29, an electric transmission system 30, and a hanging assembly 31; the hanging assembly 31 connected to the pod hanging is installed on the dragging platform 21, and the support assembly 25 and the balance adjustment assembly 26 for supporting and adjusting the center of gravity balance of the pod are also installed. The lower end of the support and positioning rod 23 is fixed to the dragging platform with bolts, and the upper end is installed on the linear bearing 24, and the linear bearing is installed on the hanging platform 22. The connection of the support and positioning rod ensures that the entire device is vertically fixed and moves up and down during lifting, and is stable and without tilting; the fixing method of the linear bearing can ensure smooth movement without obstruction. The connecting ear piece 27 is installed on the dragging platform, the ball screw assembly 28 is fixed to the connecting ear piece with bolts, and an electric transmission system 30 is installed on the upper end of the ball screw assembly. The motor of the electric transmission system drives the ball screw assembly to rotate spirally, thereby driving the entire device to move up and down. The electric transmission system is installed and fixed on the mounting seat 29, and the mounting seat is fixed to the hanging platform.

[0035] The ball screw assembly and electric transmission system of the present invention are both existing designs, wherein the ball screw assembly includes a screw, balls, nuts, end covers and a mounting seat; the electric transmission system includes a drive motor, a gear box and a mounting housing.

[0036] like Figure 3 As shown, the mounting platform 22 of the mounting and dragging device 2 is fixed to the mounting beam 17 of the fixed load-bearing device 1 by four bolts and nuts. The two devices are firmly fixed, highly stable, and have strong load-bearing capacity. Figure 4As shown, the hanging assembly 31, the supporting assembly 25, and the balancing adjustment assembly 26 of the hanging and dragging device are respectively connected and fixed to the pod in three combined ways: hanging fixation, left and right supporting fixation, and adjusting balance positioning fixation. This fixing method is customized and designed according to the supporting requirements of the hanging points of the pod shape to ensure that the connection is firm and reliable, the force is uniform, stable and safe during the hanging process.

[0037] When installing the aerial refueling pod, Figure 3 As shown, the entire equipment is connected and fixed according to the above requirements, the product assembly vehicle is placed under the hanging and dragging device 2, and the motor is reversed by controlling the remote control of the electric transmission system 30, thereby driving the ball screw assembly 28 to rotate clockwise, and the four supporting positioning rods 23 are vertically lowered along the axis bearing, so that one end of the dragging platform 21 of the hanging and dragging device is steadily lowered. When it descends to a point close to the hanging point of the aerial refueling pod, as shown in FIG. Figure 4 As shown, the mobile assembly vehicle allows the crimping lug of the mounting assembly 31 to fit between the two mounting lugs of the pod, and fine-tunes the holes of the two to align. The pin of the mounting assembly 31 is inserted into the hole to fix it, and then the limit nut is tightened. The two groups of support interfaces of the support assembly 25 are synchronously screwed to insert the fixed pins at the front and rear ends of the pod into the support interfaces, and then the front and rear groups of support assemblies are adjusted according to the center of gravity of the pod to ensure that the pod is balanced and limited in front and back, and then the four groups of adjustment bolts of the balance adjustment assembly 26 are screwed until they are in contact with the reinforcement platform at the upper end of the pod, and the four groups of adjustment bolts are adjusted according to the degree of deflection of the pod to the left and right to ensure that the pod is not deflected to the left and right. At the same time, the pod can ensure its stability when bearing the backward drag force, and the force is evenly applied in the fixed position.

[0038] Control the remote control to make the motor rotate forward, drive the ball screw assembly to rotate counterclockwise, and slightly lift the hanging towing device connected to the pod. Observe whether the position of the pod is skewed and whether the depth of the pin shaft of the pod inserted into the support interface of the support assembly is the same. If the depths on both sides are different, adjust the bolts of the balance adjustment assembly 26 to make the depth of the pin shaft interface the same. Then adjust the support assembly so that the support interface contacts and gets stuck with the reinforcement platform at the upper end of the pod. Finally, control the remote control to hang the pod in the appropriate position. Carry out the assembly work. During the assembly process, control the lifting and lowering of the towing platform to adapt to the requirements of different assembly positions. It can meet the hanging of two pods at the same time and carry out the assembly work synchronously. After the pod assembly is completed, control the towing platform to lower the pod and place it on the assembly vehicle, unscrew the limit nut of the hanging assembly, take out the pin shaft, and control the towing platform to rise to a fixed position after it is disengaged from the pod.
