Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0027] In this embodiment, referring to Figure 1 and Figure 2 , it includes a mounting base 14. An inner sleeve 9 is provided at the upper end of the mounting base 14, and the bottom of the inner sleeve 9 is fixedly installed on the mounting base 14 through bolts; an outer sleeve 6 is slidably sleeved on the inner sleeve 9, and a felt ring 11 is sleeved on the outer end of the bottom of the inner sleeve 9. The felt ring 11 is in contact with the inner wall of the outer sleeve 6, and the closure between the bottom of the inner sleeve 9 and the outer sleeve 6 is sealed through the felt ring 11, which has a dust-proof effect on the internal structure of the structure. A device mounting base 1 is provided at the upper end of the outer sleeve 6, and a plurality of mounting holes are provided on the device mounting base 1 to facilitate the stable support of the cylindrical aircraft.

[0028] In this embodiment, referring to Figure 1 and Figure 2 , an angle adjustment mechanism is provided at the lower end of the mounting base 14, and the angle adjustment mechanism is used to adjust the offset angle of the device mounting base 1; the angle adjustment mechanism includes a ball head screw 15, a ball head cover 16 and a ball head base 17.

[0029] A threaded hole is formed in the middle of the mounting base 14. The upper end of the ball head screw 15 is threadedly connected to the threaded hole of the mounting base 14. At the same time, a screw position is reserved between the upper end of the ball head screw 15 and the threaded hole, so that the upper end of the ball head screw 15 is fastened to the mounting base 14 by a fastening screw 12, strengthening the stability of the connection between the ball head screw 15 and the mounting base 14, playing an anti-loosening role, and preventing the ball head screw 15 from accidentally falling off the mounting base 14;

[0030] A spherical groove is formed in the ball head base 17. The lower end of the ball head screw 15 is movably installed in the spherical groove, so that the lower end of the ball head screw 15 can rotate in the spherical groove, thereby adjusting the orientation of the upper end of the ball head screw 15. The ball head cover 16 is installed on the upper end of the ball head base 17, and the ball head cover 16 is fixedly installed on the upper end surface of the ball head base 17 by screws. An arc-shaped cavity is provided in the middle of the ball head cover 16, and the arc-shaped cavity is fitted and installed on the surface of the lower end of the ball head screw 15.

[0031] Rotate the ball head screw 15 to adjust the orientation of the mounting base 14. When the ball head screw 15 is adjusted to the corresponding orientation, tighten the screw so that the ball head cover 16 fixes the ball head screw 15 and stops it from rotating, thereby realizing the adjustment of the orientation of the device mounting base 1.

[0032] On the one hand, it is convenient to adjust the device mounting base 1 at multiple angles, which is suitable for various attitude supports of cylindrical aircraft and suitable for various application scenarios; on the other hand, it can also make the ball head base 17 adapt to a ground plane with a certain slope, ensuring that the entire manual lifting support device always maintains a vertical support.

[0033] In this embodiment, referring to Figure 1 and Figure 2 , a lifting mechanism is provided in the inner sleeve 9, and the lifting mechanism is used to adjust the height of the device mounting base 1; the lifting mechanism includes a lifting screw 2, a sleeve nut 7 and a bearing 4. The sleeve nut 7 is installed in the inner sleeve 9, and the lower end of the lifting screw 2 is threadedly passed through the sleeve nut 7 and located in the inner sleeve 9, so that the lifting screw 2 rotates relative to the thread in the sleeve nut 7. The sleeve nut 7 is made of copper material, so that the sleeve nut 7 and the lifting screw 2 will not be stuck due to excessive friction during the mutual transmission process;

[0034] At the same time, a baffle 10 is provided at the bottom of the lifting screw 2 to facilitate the stability and protection of the lifting screw 2. A rotating handle is provided at the upper end of the lifting screw 2 to facilitate the operator to rotate the lifting screw 2;

[0035] A through groove is provided on the device mounting base 1, and a receiving groove is provided at the lower end port of the through groove. The first bearing 4 is installed in the receiving groove. The upper end of the lifting screw rod 2 passes through the first bearing 4 and penetrates out of the through groove. The upper end port of the outer sleeve 6 is installed with a second bearing 5, and the lifting screw rod 2 passes through the second bearing 5. By passing and fixing the lifting screw rod 2 through the first bearing 4 and the second bearing 5 together, on the one hand, the connection of the lifting screw rod 2 on the outer sleeve 6 and the device mounting base 1 is stabilized on the premise of not affecting the rotation of the lifting screw rod 2, and on the other hand, it is convenient for the operator to rotate the lifting screw rod 2 and improve the operability of the lifting screw rod 2.

[0036] By rotating the lifting screw rod 2, the lifting screw rod 2 moves along the vertical direction of the sleeve nut 7, so that the upper end of the lifting screw rod 2 drives the outer sleeve 6 and the device mounting base 1 to move in the vertical direction, thereby realizing the adjustment of the height of the device mounting base 1, and further adjusting the attitude position of the cylindrical aircraft.

[0037] In this embodiment, referring to Figure 2 , a rubber sealing ring 3 is sleeved on the upper end of the lifting screw rod 2, and the rubber sealing ring 3 is in contact with the inner wall of the through groove, so that the gap at the upper end of the structure is sealed by the rubber sealing ring 3; at the same time, the bottom of the structure is also sealed by the felt ring 11, so that the rubber sealing ring 3 and the felt ring 11 jointly protect the inside of the structure from dust.

[0038] In this embodiment, referring to Figure 2 , a guide key 8 is provided on the outer side of the inner sleeve 9, a key groove is provided on the inner side arm of the outer sleeve 6, and the guide key 8 is slidably arranged in the key groove to guide the vertical movement of the outer sleeve 6.

[0039] In this embodiment, referring to Figure 1 , an oil cup 13 is provided on the outer surface of the outer sleeve 6, and the oil cup 13 serves as an interface for filling and replacing lubricating oil into the internal structure space of the device.

[0040] The working principle of this embodiment: By adjusting the ball head screw rod 15, the device mounting base 1 is made horizontal, and then fixed by the ball head cover 16. Then, the device mounting base 1 is connected and fixed to the cylindrical aircraft loading device by screws. The operating handle rotates forward and backward to make the lifting screw rod 2 drive the device mounting base 1 to lift and lower, thereby realizing the adjustment of the height of the cylindrical aircraft. The lifting stroke is determined by the leveling requirement of the cylindrical aircraft loading device. Finally, the reliable support and fast and convenient leveling of the entire cylindrical aircraft loading device are realized, providing a horizontal operation platform for the loading process of the cylindrical aircraft and improving the loading efficiency of the cylindrical aircraft.

[0041] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly.
