DETAILED DESCRIPTION

[0034] The present invention is now further described in conjunction with the accompanying drawings. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0035] like Figure 1-Figure 3 As shown, a hatch door flipping and lifting mechanism includes an assembly frame 100, a positioning assembly 200, a bracket 300, a limiting assembly 400 and a hanger 500. A hatch door 600 in a vertical state is placed on the side of the assembly frame 100, the positioning assembly 200 is installed on the top front side of the assembly frame 100, the limiting assembly 400 is arranged on the top and right side of the bracket 300, and the hanger 500 lifts the hatch door 600. Through the arrangement of the positioning assembly 200, the bracket 300 and the limiting assembly 400, the positioning assembly 200 accurately positions the hatch door 600 on the assembly frame 100 at a theoretical position for accurate lifting by the hanger 500, the bracket 300 provides stable support for the hatch door 600, and the limiting assembly 400 ensures that the hatch door 600 lies accurately on the bracket 300, so as to achieve stable posture adjustment and flipping of the hatch door 600, and the operation is convenient and safe. Specifically, the assembly frame 100 is a prior art, and its specific structure will not be described in detail here.

[0036] like Figure 3 and Figure 4As shown, the hanger 500 includes a hanger rod 510, a hanger rope 520 and a hanger 530. The top and middle of the hanger 530 are respectively provided with joints 531, and the bottom is installed with a rotating shaft 540. The top of the hanger rope 520 is connected to the end of the hanger rod 510, and the bottom is connected to the joint 531. The upper and lower ends of the hanger 530 near the side of the cabin door 600 are respectively connected to the convex surface of the cabin door 600 through bushings 550. Through the setting of the hanger 500, the mechanism can be used in different positions and postures in the same section, and can also be used in different models and different aircraft parts, with stronger versatility. Specifically, the bushing 550 has a thickness of 8mm, a compression amount of 50%, and a built-in eccentric adjustment function, which is compatible with R1000-R4000mm cabin door 600 or fuselage wall panel products, further improving versatility.

[0037] The purpose of providing joints 531 at the top and the middle of the sling 530 is to realize the slinging of the hatch 600 in different postures. For example, when the bottom end of the sling rope 520 is connected to the joint 531 at the top of the sling 530, the hatch 600 is slinged in one posture; when the bottom end of the sling rope 520 is connected to the joint 531 in the middle of the sling 530, the hatch 600 is slinged in another posture. When slinging in different postures, it is only necessary to connect the sling rope 520 to the corresponding joint 531, without the need to frequently disassemble the sling 530, and the operation is convenient.

[0038] like Figure 1 , Figure 5 and Figure 6 As shown, the positioning assembly 200 includes a crossbeam 210, a first hoist 220, a positioning rod 230 and a positioning device 240. The crossbeam 210 is slidably mounted on the front side of the top of the assembly frame 100. The first hoist 220 is mounted on the left and right ends of the top of the assembly frame 100, and its driving end is connected to the end of the crossbeam 210. The positioning rod 230 is obliquely mounted on the side of the crossbeam 210 away from the assembly frame 100 to position the hatch 600 on the assembly frame 100. The positioning device 240 is mounted on the top of the crossbeam 210 and corresponds to the positioning hole on the assembly frame 100. After the positioning rod 230 positions the hatch 600 on the assembly frame 100, when the hatch 600 needs to be hoisted, the positioning device 240 exits the positioning hole, and the first hoist 220 drives the crossbeam 210 to rise and then drives the positioning rod 230 to rise synchronously, so that the positioning rod 230 is away from the hatch 600, thereby avoiding the collision between the hatch 600 and the positioning rod 230 during the hoisting process.

[0039] like Figure 2 and Figure 7As shown, the limiting assembly 400 includes a limiting plate 410 and an anti-slip group 420. The limiting plates 410 are several pieces, which are installed in parallel and at intervals at the top of the bracket 300. The front and rear ends of the limiting plates 410 are respectively provided with notches 411 to avoid the sling 520 and the sling 530. The anti-slip group 420 is installed on the right side of the bracket 300 to limit the rotating shaft 540. Through the setting of the anti-slip group 420, the rotating shaft 540 is limited during the flipping process of the hatch 600. Specifically, there are three limiting plates 410, wherein the height of the left limiting plate 410 is greater than the height of the right limiting plate 410, and the height of the right limiting plate 410 is greater than the height of the middle limiting plate 410.

[0040] like Figure 7-Figure 9 As shown, the anti-slip group 420 includes a second lifter 421, a stopper block 422 and a stopper pin 423. The second lifter 421 is vertically installed on the right side of the bracket 300, and its driving end is connected to the stopper block 422. A U-shaped groove 4221 is provided in the middle of the top of the stopper block 422, and one end of the stopper pin 423 is plugged into the side wall of the U-shaped groove 4221. When the hatch 600 is turned over, the hanger 500 lifts the hatch 600 until the shaft 540 falls into the U-shaped groove 4221, and then the stopper pin 423 is installed for position limiting. Under the weight of the hanger 530 and the hatch 600, the hatch 600 automatically turns over to lie flat on the bracket 300, and the hanger 530 enters the gap 411. The self-turning is achieved by the weight of the hanger 530 and the hatch 600, which is more efficient and convenient. At the same time, the bracket 300 provides support and better stability. When the hatch 600 is riveted, the second lifter 421 drives the limit block 422 to rise and fall, thereby adjusting the posture of the hatch 600 to facilitate riveting work in different areas of the hatch 600. Specifically, the notches of the U-shaped groove 4221 are relatively formed with inclined surfaces 42211, so that the rotating shaft 540 can fall into the U-shaped groove 4221.

[0041] like Figure 10-13 As shown, the hatch flipping and lifting mechanism also includes an inspection frame 700 and a transport box 800. The hatch 600 in a vertical state is placed on the side of the inspection frame 700. The transport box 800 includes a box body 810, a tunnel frame 820 and a clamping assembly 830. The tunnel frame 820 is arranged in the box body 810, and the clamping assembly 830 is arranged at the left and right ends of the tunnel frame 820. By setting the clamping assembly 830, the hatch 600 on the tunnel frame 820 is fixed to prevent it from moving during transportation. Specifically, the inspection frame 700 is a prior art.

[0042] like Fig.13As shown, the clamping assembly 830 includes a reference plate 831, a first screw sleeve 832, a first screw rod 833, a cushion block 834 and a tension clamp 835. The reference plate 831 is arranged at the right end of the tunnel frame 820. There are a plurality of first screw sleeves 832, which are arranged side by side and spaced apart at the left end of the tunnel frame 820. The first screw rod 833 is passed through the first screw sleeve 832. The cushion block 834 is installed at the right end of the first screw rod 833. The tension clamp 835 is installed at the right side of the first screw sleeve 832 and is sleeved on the first screw rod 833. When the hatch 600 is placed on the tunnel frame 820, the first screw rod 833 is adjusted to move axially until the cushion block 834 makes the hatch 600 contact the reference plate 831.

[0043] like Figure 7 and Figure 8 As shown, a support assembly 900 and a roller 1000 are installed at the bottom end of the bracket 300. The support assembly 900 includes a second screw sleeve 910, a second screw rod 920 and a foot 930. The second screw sleeve 910 is respectively installed on the left and right sides of the bottom end of the bracket 300, the second screw rod 920 is inserted into the second screw sleeve 910, the foot 930 is installed at the bottom end of the second screw rod 920, and the roller 1000 is installed at the four corners of the bottom end of the bracket 300. The setting of the support assembly 900 plays a supporting role for the bracket 300.

[0044] During operation, the bottom end of the lifting rope 520 is connected to the joint 531 at the top of the lifting device 530, the lifting rod 510 is connected to the overhead crane (not shown in the figure), and the lifting device 530 is connected to the convex surface of the hatch 600, and the hatch 600 located on the assembly frame 100 is lifted; the rotating shaft 540 is dropped into the U-shaped groove 4221, and the limit pin 423 is installed to prevent the hatch 600 from falling off, and then the hatch 600 is lifted by the weight of the hatch 600 and the lifting device 530. 0 is flipped to lie flat on the bracket 300; the second hoist 421 drives the hatch door 600 to rise and fall and adjust its posture to complete the riveting work in different areas; after the riveting work is completed, the hatch door 600 is lifted by the crane and the joint 531 in the middle of the hoist 530. If the hatch door 600 is lifted to the inspection frame 700, the hatch door 600 is still lifted by the joint 531 at the top of the hoist 530; finally, the hatch door 600 is lifted into the transport box 800 by the crane.
