[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0025] like Figures 1 to 3 As shown, the blind zone painting device for the fuselage section at the leading edge of the vertical tail of a wide-body aircraft dock according to the present invention includes a steel structure installation platform 1 and three sets of operating platforms 2. The steel structure installation platform 1 is symmetrically arranged along both sides of the fuselage. Two operating platforms 2 are installed as a group along the width direction of the steel structure installation platform 1. One set of operating platforms 2 is located on the left side of the steel structure installation platform 1 along its length direction, one set of operating platforms 2 is located in the middle of the steel structure installation platform 1 along its length direction, and one set of operating platforms 2 is located on the right side of the steel structure installation platform 1 along its 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 installed on the fixed steel structure 21. The guide structure 24 is installed between the fixed steel structure 21 and the lifting steel structure 22. The lifting mechanism 23 is installed on the lifting steel structure 22 and is used to drive the lifting steel structure 22 to lift. The platform mechanism 25 is installed at the lower end of the lifting steel structure 22.

[0027] Furthermore, in the blind zone painting device for the fuselage section at the leading edge of the vertical tail of a wide-body aircraft dock according to the present invention, the lifting mechanism 23 includes a mounting platform 231, a reduction motor 232, a coupling 234, a lifting platform 235, and a lifting rod 236. The mounting platform 231 is fixed in the middle of the lifting steel structure 22, the reduction motor 232 is installed on one side of the lifting steel structure 22, the lifting platform 235 is symmetrically installed at both ends of the mounting platform 231, and the output end of the reduction motor 232 is connected to the input end of the lifting platform 235 through the coupling 234. The lifting rod... 236 is mounted on the steel structure installation platform 1 via a hinge shaft. The output end of the lifting machine 235 is connected to the lifting rod 236 for lifting. The driving force generated by the geared motor 232 is distributed to the lifting machine 235 via the coupling 234, causing the lifting machine 235 to move along the lifting rod 236 and drive the lifting steel structure 22 to rise and fall. When the geared motor 232 provides driving force to one end of the lifting machine 235 through the coupling 234, the lifting rod 236 rotates on the steel structure installation platform 1 via the hinge shaft, which allows the lifting steel structure 22 to be tilted and adjusted.

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

[0029] Furthermore, in the aforementioned blind zone painting device for the fuselage section at the leading edge of the vertical tail of the wide-body aircraft dock, a limiting groove 211 is provided on the side of the fixed steel structure 21 near the lifting steel structure 22. The two sides of the limiting groove 211 are slidably connected to the horizontal guide wheel 242, and the bottom of the limiting groove 211 is slidably connected to the vertical guide wheel 241. When the lifting steel structure 22 is raised and lowered within the fixed steel structure 21, it can be guided and slid by the horizontal guide wheel 242 and the vertical guide wheel 241, effectively avoiding deviation during the raising and lowering process that could cause damage to the aircraft body.

[0030] Furthermore, in the aforementioned painting device for the blind zone of 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, a guide 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 disposed inside the painting platform 251. The guide wheel 253 is installed on one side of the painting platform 251 and is circumferentially connected to the pull-out plate 252. The railing 254 is disposed on the outside of the painting platform 251. During painting operations, the pull-out plate 252 can be extended close to the aircraft body by driving the guide wheel 253. The railing 254 effectively ensures the safe passage of platform operators.

[0031] Specifically, during the painting operation, the operating platform 2 installed on the steel structure mounting platform 1 is controlled separately. First, the operating platform 2 closest to the aircraft body is adjusted so that the corresponding lifting steel structures 22 on the left, middle, and right sides are raised and lowered respectively through the lifting mechanism 23. The platform mechanism 25 stops raising and lowering when it approaches the aircraft body, ensuring that the platform mechanism 25 on the inner operating platform 2 will not collide with the aircraft. Then, the outer operating platform 2 is adjusted so that the corresponding lifting steel structures 22 on the left, middle, and right sides are raised and lowered respectively through the lifting mechanism 23. During the raising and lowering process, the reduction motor 232 provides power, which is transmitted to the elevator 235 via the coupling 234. The machine 235 moves up and down along the lifting rod 236, so that the lifting steel structure 22 moves up and down along the upper limit groove 211 of the fixed steel structure 21 through the vertical guide wheel 241 and the horizontal guide wheel 242 installed on the upper two side mounting plates 243. This ensures 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, so as to carry out the painting operation. At this time, the pull-out plate 252 inside the painting platform 251 is extended infinitely close to the aircraft body through the guide wheel 253 to adapt to the tail taper of the aircraft. At this time, the operator can enter the pull-out plate 252 through the side of the painting platform 251 with the railing 254 to carry out the painting operation.

[0032] In summary, compared with the prior art, the paint spraying device for the blind zone of the fuselage section at the leading edge of the vertical tail of the wide-body aircraft dock of the present invention has the following advantages and beneficial effects:

[0033] The invention has a simple overall structure and is easy to operate. The cooperation between the steel structure installation platform and three sets of operating platforms allows for simultaneous painting operations on both sides of the aircraft, effectively improving work efficiency. By adjusting the lifting height of the operating platform and the extension length of the platform mechanism, it can adapt to the taper of the transition section between the wide-body fuselage and the tail, thereby effectively avoiding the generation of blind spots in painting.
