[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] like Figures 1 to 3 As shown, the blind area painting device for the front fuselage section of the vertical tail of a wide-body aircraft dock of the present invention comprises a steel structure installation platform 1 and three groups of operating platforms 2. The steel structure installation platform 1 is symmetrically arranged along both sides of the fuselage. Two operating platforms 2 form a group and are respectively installed along the width direction of the steel structure installation platform 1. One group of operating platforms 2 is arranged on the left side of the steel structure installation platform 1 in the length direction, one group of operating platforms 2 is arranged in the middle of the steel structure installation platform 1 in the length direction, and one group of operating platforms 2 is arranged on the right side of the steel structure installation platform 1 in the length direction, wherein:

[0026] The operating platform 2 includes a fixed steel structure 21, a lifting steel structure 22, a lifting mechanism 23, a guide structure 24 and a platform mechanism 25. The fixed steel structure 21 is fixedly connected to the steel structure installation platform 1. The lifting steel structure 22 is arranged on the fixed steel structure 21. The guide structure 24 is arranged between the fixed steel structure 21 and the lifting steel structure 22. The lifting mechanism 23 is arranged on the lifting steel structure 22 for driving the lifting structure to rise and fall. The platform mechanism 25 is arranged at the lower end of the lifting steel structure 22.

[0027] Further, in the blind area painting device for the front fuselage section of the vertical tail of a wide-body aircraft dock of the present invention, the lifting mechanism 23 includes a mounting platform 231, a reduction motor 232, a coupling 234, a lifter 235 and a lifting rod 236. The mounting platform 231 is fixed to the middle of the lifting steel structure 22, the reduction motor 232 is installed on one side of the lifting steel structure 22, the lifter 235 is symmetrically installed at both ends of the mounting platform 231, the output end of the reduction motor 232 is connected to the input end of the lifter 235 through the coupling 234, and the lifting rod 236 is connected to the lifting rod 236. 236 is installed on the steel structure installation platform 1 through a hinge shaft, and the output end of the elevator 235 is connected to the lifting rod 236 for lifting, so that the driving force generated by the reduction motor 232 is distributed to the elevator 235 through the coupling 234, so that the elevator 235 moves along the lifting rod 236 to drive the lifting steel structure 22 to rise and fall. When the reduction motor 232 provides driving force to one end of the elevator 235 through the coupling 234, the lifting rod 236 rotates on the steel structure installation platform 1 through the hinge shaft, so that the lifting steel structure 22 can be tilted and adjusted.

[0028] Furthermore, in the above-mentioned blind spot painting device for the leading edge of the vertical tail fuselage section of a wide-body aircraft dock, the guide structure 24 includes a vertical guide wheel 241, a transverse guide wheel 242 and a mounting plate 243. The vertical guide wheel 241 is vertically arranged on the mounting plate 243, and the transverse guide wheel 242 is transversely arranged on the mounting plate 243. The mounting plate 243 is fixed to the upper end of the lifting steel structure 22 by rivets, and the distance from the mounting plate 243 to the highest point of the vertical guide wheel 241 is higher than the distance from the mounting plate 243 to the highest point of the transverse guide wheel 242.

[0029] Furthermore, in the above-mentioned blind spot painting device for the fuselage section at the leading edge of the vertical tail of a wide-body aircraft dock, a limiting groove 211 is provided on the side of the fixed steel structure 21 close to the lifting steel structure 22, and both sides of the limiting groove 211 are slidably connected to the transverse guide wheels 242, and the bottom of the limiting groove 211 is slidably connected to the vertical guide wheel. When the lifting steel structure 22 is lifted and lowered in the fixed steel structure 21, it can be guided and slid by the transverse guide wheel 242 and the vertical guide wheel, which effectively avoids damage to the fuselage caused by displacement during the lifting process.

[0030] Furthermore, in the above-mentioned blind spot painting device for the fuselage section at the leading edge of the vertical tail of a wide-body aircraft dock, the platform mechanism 25 includes a painting platform 251, a pull-out plate 252, an export wheel 253 and a railing 254. The painting platform 251 is fixedly connected to the lifting steel structure 22, the pull-out plate 252 is slidably arranged inside the painting platform 251, the export wheel 253 is installed on one side of the painting platform 251, the export wheel 253 is rollingly connected to the pull-out plate 252 in the circumferential direction, and the railing 254 is arranged on the outside of the painting platform 251. When performing painting operations, the export wheel 253 can be driven to extend the pull-out plate 252 close to the fuselage for painting operations, and the railing 254 effectively ensures the safe passage of the platform operator.

[0031] Specifically, during the painting operation, the operating platform 2 installed on the steel structure installation platform 1 is controlled respectively. First, the operating platform 2 close to the inner side of the fuselage is adjusted so that the corresponding lifting steel structures 22 on the left, middle and right sides are adjusted to be lifted and lowered respectively through the lifting mechanism 23. The lifting and lowering of the platform mechanism 25 is stopped after the platform mechanism 25 approaches the fuselage to ensure that the platform mechanism 25 on the inner operating platform 2 will not collide with the aircraft. At this time, the outer operating platform 2 is adjusted so that the corresponding lifting steel structures 22 on the left, middle and right sides are adjusted to be lifted and lowered respectively through the lifting mechanism 23. During the lifting process, the reduction motor 232 provides power and transmits it to the elevator 235 through the coupling 234. The lifting and lowering The machine 235 is lifted and lowered along the lifting rod 236, so that the lifting steel structure 22 is lifted and lowered along the upper limit groove 211 of the fixed steel structure 21 through the vertical guide wheels 241 and the horizontal guide wheels 242 installed on the mounting plates 243 on both sides of the upper end, ensuring that the distance between the platform mechanism 25 on the outer operating platform 2 and the platform mechanism 25 on the inner operating platform 2 is greater than the height of the operator to facilitate the painting operation. At this time, the pull-out plate 252 inside the painting platform 251 is extended to as close to the aircraft body through the guide wheel 253 to adapt to the taper of the tail of the aircraft. At this time, the operator can enter the pull-out plate 252 through the side of the painting platform 251 where the railing 254 is fixed to perform the painting operation.
