[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Example 1, referring to Figures 1-3This is the first embodiment of the present invention. This embodiment provides a fixed bracket for fuselage maintenance with a protective structure, which can achieve the effect of supporting the middle of the aircraft. It includes a lifting component, including a support frame 10 and an auxiliary frame 11. A set of directional wheels is provided on the bottom front side of the support frame 10, and a set of universal wheels is provided on the bottom rear side of the support frame 10. Two universal wheels are symmetrically provided on the bottom of the auxiliary frame 11. A first threaded cylinder 12 is rotatably connected inside the support frame 10. A first load-bearing screw 13 is threadedly connected inside the first threaded cylinder 12. A first support block 14 is fixedly connected to the top of the first load-bearing screw 13. A stabilizing component 15 for supporting the middle of the aircraft is provided inside the auxiliary frame 11.

[0023] Specifically, the stabilizing component 15 includes a second threaded cylinder 151, which is rotatably connected inside the auxiliary frame 11. A second load-bearing screw 152 is threadedly connected inside the second threaded cylinder 151. A second support block 153 is fixedly connected to the top of the second load-bearing screw 152. A guide post 154 is fixedly connected to the bottom of the second support block 153. A first guide block 155 is fixedly connected to the inner wall of the auxiliary frame 11. A sliding rod 156 is fixedly connected to the front of the auxiliary frame 11. A second guide block 157 is fixedly connected to the inner wall of the support frame 10. A lifting plate 158 is fixedly connected to the bottom of the second support block 153. A lifting plate 158 is fixedly connected to the back of the support frame 10. There is a T-shaped block 159, and the lifting plate 158 is slidably connected to the T-shaped block 159. The sliding rod 156 and the second guide block 157 facilitate the movement and guidance of the auxiliary frame 11, and facilitate the movement of the second support block 153 to a suitable position. The second support block 153 facilitates the support of the middle part of the aircraft, thereby ensuring the stability of the middle part of the aircraft, facilitating the disassembly and maintenance of the middle part of the aircraft, and avoiding the risk of unstable center of gravity, aircraft rollover, or structural bending / damage to the fuselage. The lifting plate 158 and the T-shaped block 159 facilitate the limiting of the stored auxiliary frame 11, and facilitate the movement of the support frame 10 and the auxiliary frame 11.

[0024] Furthermore, a through hole is provided inside the first guide block 155 at the position corresponding to the guide post 154, and the guide post 154 is slidably connected in the through hole, which facilitates the smooth lifting and lowering of the second support block 153.

[0025] The second guide block 157 has a through hole at the position corresponding to the slide rod 156, and the slide rod 156 is slidably connected in the through hole to facilitate the guiding work of the auxiliary frame 11.

[0026] In use, by moving the two support frames 10 to the front and rear fuselages of the aircraft respectively, rotating the first threaded cylinder 12, with the cooperation of the first load-bearing screw 13 and the first support block 14, the aircraft is lifted upward. By rotating the second threaded cylinder 151, the second load-bearing screw 152 is moved upward a certain distance. With the cooperation of the guide column 154 and the first guide block 155, the second support block 153 is guided, so that the lifting plate 158 is moved away from the T-block 159, thereby releasing the restriction on the auxiliary frame 11. By moving the auxiliary frame 11, the auxiliary frame 11 is brought closer to the middle area of ​​the aircraft. After the auxiliary frame 11 is moved to a suitable position and restricted, the second threaded cylinder 151 is rotated again, so that the second support block 153 contacts the aircraft, thereby supporting the middle area of ​​the aircraft.

[0027] Example 2, refer to Figures 4-5 This is the second embodiment of the present utility model. Unlike the previous embodiment, this embodiment provides a limiting component for a fixed bracket for fuselage maintenance with a protective structure, based on embodiment 1. This solves the problem that the support frame is not easy to move. It includes a limiting component, including an L-shaped insert rod 20, which is fixedly connected to the outside of the auxiliary frame 11. An adjustment component 21 is provided on the outside of the auxiliary frame 11.

[0028] Specifically, the adjustment component 21 includes a threaded sleeve 211, which is rotatably connected to the outside of the auxiliary frame 11. A stud 212 is threadedly connected inside the threaded sleeve 211, and a pressure block 213 is rotatably connected to the bottom of the stud 212. A positioning plate 214 is fixedly connected to the outside of the auxiliary frame 11, and the threaded sleeve 211 is slidably connected to the positioning plate 214. A handle 215 is fixedly connected to the outside of the threaded sleeve 211. The stud 212 and the pressure block 213 facilitate the limiting of the moved auxiliary frame 11, thereby ensuring the stability of the auxiliary frame 11. The positioning plate 214 facilitates the positioning of the rotated threaded sleeve 211, making it easy for the L-shaped insert 20 to be inserted into the inside of the pressure block 213. This allows the operator to hold the handle 215 and push the auxiliary frame 11. After the auxiliary frame 11 is stored, it also facilitates the movement of the support frame 10.

[0029] Furthermore, the adjustment components 21 are provided in two sets, and the two sets of adjustment components 21 are symmetrically arranged on the outside of the auxiliary frame 11, which facilitates the stable support or movement of the auxiliary frame 11; the inside of the pressure block 213 is provided with a groove at the position corresponding to the L-shaped insert 20, and the L-shaped insert 20 is inserted into the groove, which facilitates the limiting work of the rotated pressure block 213.

[0030] In use, rotating the stud 212 causes the pressure block 213 to move downwards and contact the ground, thus limiting the movement of the auxiliary frame 11. When the position of the auxiliary frame 11 needs to be adjusted, the pressure block 213 is moved away from the ground, and the threaded sleeve 211 is rotated 90 degrees, so that the threaded sleeve 211 fits against the positioning plate 214, making the handle 215 perpendicular to the ground. Rotating the stud 212 in the opposite direction causes the pressure block 213 to move toward the L-shaped insert 20, so that the L-shaped insert 20 is inserted into the groove opened inside the pressure block 213, thus completing the rotation of the pressure block 213 and limiting the threaded sleeve 211 and the handle 215. By holding the handle 215, it is convenient to push the auxiliary frame 11 to move. After the auxiliary frame 11 is stored, it is convenient to move the support frame 10 and the auxiliary frame 11.
