[0032] The embodiment of the present application discloses a rear tail maintenance platform, including a platform 1, wherein a plurality of first flat pads 2 are fixedly connected to the top of the platform 1, and a railing 3 is fixedly connected to the top of the plurality of first flat pads 2, a stair frame 4 is fixedly connected to the front side of the platform 1, a support frame 5 is fixedly connected to the bottom of the platform 1, a plurality of second flat pads 6 are installed on the inner side of the support frame 5, a plurality of anti-slip screws 7 are installed inside the plurality of second flat pads 6, a plurality of second flat pads 6 are fixedly connected to the front side of the ground support 8, a plurality of third flat pads 9 are fixedly connected to the bottom end of the support frame 5, a plurality of third flat pads 9 are fixedly connected to the bottom end of the plurality of third flat pads 9, and a universal wheel 11 is installed on the bottom of the plurality of elastic pads 10, A baffle 12 is fixedly connected to the outer side of the first flat pad 2, and multiple first flat pads 2 are fixedly connected to the top of the platform 1 by screws. The bottom of the platform 1 is welded and fixed to the top of the support frame 5, and multiple anti-slip screws 7 are threadedly connected to the bottom end of the inner side of the support frame 5. Multiple universal wheels 11 are used to facilitate the staff to quickly move the support frame 5 to the tail position that needs to be inspected, which greatly improves the maneuverability of the maintenance platform. At the same time, multiple third flat pads 9 and spring washers 10 can reduce the wear of the universal wheel 11 on the ground during movement, which is convenient for extending the service life of the universal wheel 11. Multiple ground supports 8 can evenly disperse the weight of the support frame 5, so that the support frame 5 has higher stability.
[0033] Reference Figure 5 As shown, two first support plates 13 are installed on the left and right sides of the support frame 5, and the bottoms of the two first support plates 13 on the left and right are fixedly connected with second support plates 14. The multiple first support plates 13 and the second support plates 14 can provide effective supporting force for the movement of the push rod 20, so that the multiple push rods 20 can be more stable when moving.
[0034] Reference Figure 6As shown, both ends of the bottom of the left and right second support plates 14 are fixedly connected with the first shaft support 15, and multiple first connecting rods 16 are installed inside the first shaft support 15. The bottom ends of multiple first connecting rods 16 are fixedly connected with electric hydraulic rods 17, and the bottom ends of multiple electric hydraulic rods 17 are fixedly connected with second connecting rods 18. Second shaft supports 19 are installed on the outsides of multiple second connecting rods 18, and the bottom ends of multiple second shaft supports 19 are fixedly connected with pushing rods 20. The pushing rod 20 can be pushed downward by the electric hydraulic rod 17. The first connecting rod 16 is movably connected to the inner side of the first shaft support 15, so that the top end of the electric hydraulic rod 17 can move at multiple angles. The second connecting rod 18 is movably connected to the inner side of the second shaft support 19, so that when the electric hydraulic rod 17 pushes the pushing rod 20 to move, it can move with the pushing rod 20, so that the pushing rod 20 can better push the support base 22 to move.
[0035] Reference Figure 4 As shown, a third axis support 21 is installed on the outer side of one end of each of the plurality of push rods 20, and a support base 22 is fixedly connected to the bottom of the other end of each of the plurality of push rods 20. The third axis support 21 is used to support one end of the push rod 20, so that the push rod 20 can drive the support base 22 to support the ground through the other end, thereby increasing the contact area between the support frame 5 and the ground, and ensuring the safety and stability of maintenance personnel when working on the platform.
[0036] Working principle of the utility model: The utility model designs a rear tail maintenance platform, the specific structure is as shown in the attached manual Figure 1-7As shown, in the technical solution, through the mutual cooperation between various structures, when the rear tail of the helicopter needs to be repaired, the support frame 5 is first pushed to the position where maintenance is required by multiple universal wheels 11, and then multiple ground supports 8 are rotated, and the second flat pad 6 is fixed to the inner bottom end of the support frame 5 by multiple anti-slip screws 7, so that multiple ground supports 8 stably support the support frame 5, which can effectively prevent the staff from shaking when repairing at the top of the platform 1. When the multiple ground supports 8 support the support frame 5 to rise, the multiple electric hydraulic rods 17 are started, and the multiple electric hydraulic rods 17 are used to push the support base 22 to move downward, and the first shaft support 15 and the second shaft support 19 are connected to the electric hydraulic rods 17. The first connecting rod 16 and the second connecting rod 18 at the end are movably connected internally, so that when the electric hydraulic rod 17 pushes the second shaft support 19, it can move along with one end of the second shaft support 19. At the same time, it is movably connected with the outside of one end of the third shaft support 21 through the inside of the third shaft support 21, so that the other end of the support push rod 20 drives the support base 22 to support the ground, which can provide effective support for the bottom end of the support frame 5 to ensure that the maintenance platform can remain stable during the maintenance process. Then the staff can move to the top of the platform 1 through the stair frame 4, and use the railing 3 to surround the top of the platform 1 to ensure the safety of the staff. Finally, the rear tail of the helicopter can be inspected through the inspection port in the middle of the railing 3.
