Description

Technical Field

[0001] This utility model belongs to the field of aircraft float support, specifically, it relates to an aircraft landing gear float support. Background Technology

[0002] Aircraft floats are the primary buoyancy devices for seaplanes, enabling them to take off, land, taxi, and moor routinely on water. They are precisely designed, taking into account both hydrodynamics and aerodynamics, to provide stable buoyancy and good flight performance. Currently, floats are typically mounted on the aircraft's landing gear. Due to their inherent size and mass, floats generally require lifting during assembly to facilitate installation. Existing methods for lifting floats typically involve placing them on a device that allows for vertical movement of the entire float. This vertical movement facilitates locating the installation position for installation. However, in some cases, the installation position of the aircraft may not correspond perfectly with the installation position of the float at one time, and the two installation positions may not be on the same plane. This may require a certain change in the local position of the float, or even an adjustment to a certain tilt angle. Most existing lifting devices raise and lower the float as a whole, which makes it difficult to tilt the float locally, thus hindering the installation of the float. Utility Model Content

[0029] In this embodiment, a lifting assembly 200 and a supporting assembly 300 are provided. The lifting assembly 200 includes a first lifting unit 210 and a second lifting unit 220; the first lifting unit 210 and the second lifting unit 220 are spaced apart; the first lifting unit 210 and the second lifting unit 220 are respectively connected to the supporting assembly 100; the supporting assembly 300 includes a first supporting unit 310 and a second supporting unit 320; the first supporting unit 310 is connected to the first lifting unit 210; the second supporting unit 320 is connected to the second lifting unit 220. Unit 220 is connected; the first lifting unit 310 and the second lifting unit 320 are arranged at intervals. When the first lifting unit 310 and the second lifting unit 320 lift the pontoon, since the first lifting unit 310 and the second lifting unit 320 are two independent lifting mechanisms, the first lifting unit 310 and the second lifting unit 320 can make more convenient adjustments to the local position of the pontoon, so that the pontoon can be adjusted to a horizontal state as a whole, or it can be evenly adjusted to an inclined device according to the installation position, thereby facilitating the installation of the pontoon.

[0031] The second lifting unit 220 includes a second turntable 221, a second drive rod 222, a second driving gear 223, a second driven gear 224, a fourth lead screw 225, a second solenoid 226, a fifth lead screw 227, and a sixth lead screw 228. One end of the second drive rod 222 along its axial direction is connected to the second turntable 221, and the other end is connected to the second driving gear 223. The outer peripheral surface of the second drive rod 222 is rotatably connected to the support assembly 100. The inner peripheral surface of the second driven gear 224 is fixedly connected to the outer peripheral surface of the fourth lead screw 225. The second driving gear 223 meshes with the second driven gear 224. One end of the fourth lead screw 225 along its axial direction is rotatably connected to the support assembly 100. The outer peripheral surface of the fourth lead screw 225 is fixedly connected to the outer peripheral surface of the fourth lead screw 225. The inner circumferential surfaces of the two helical tubes 226 are threaded together; the second helical tube 226 and the second driven gear 224 are spaced apart; one end of the second helical tube 226 away from the second driven gear 224 is connected to the second lifting unit 320; the outer circumferential surfaces of the fifth lead screw 227 and the sixth lead screw 228 are respectively movably connected to the support assembly 100; one end of the fifth lead screw 227 away from the support assembly 100 along its axial direction is connected to the second lifting unit 320; one end of the sixth lead screw 228 away from the support assembly 100 along its axial direction is connected to the second lifting unit 320; the outer circumferential surfaces of the fifth lead screw 227 and the sixth lead screw 228 are respectively threaded together with the second partition nut 229; the second partition nut 229 abuts against the support assembly 100.

[0032] In this embodiment, by rotating the first turntable 211, the first drive rod 212 can drive the first drive gear 213 to rotate, thereby enabling the first lead screw 215 to drive the first lifting unit 310 to move up and down in the vertical direction. Similarly, by rotating the second turntable 221, the second lifting unit 320 can also move up and down in the vertical direction, thereby enabling targeted adjustment of the float positions on the first lifting unit 310 and the second lifting unit 320. In this embodiment, by setting the first partition nut 219 and the second partition nut 229, when the float is positioned with the aircraft, the two first partition nuts 219 can position the second lead screw 217 and the third lead screw 218, and the two second partition nuts 229 can position the fifth lead screw 227 and the sixth lead screw 228. This ensures that when the float is positioned with the aircraft landing gear, the float remains in a relatively stable state and is not easily shaken, thus facilitating the installation of the float.

[0033] In some embodiments of this utility model, such as Figure 1 , Figure 2As shown, the first lifting unit 310 includes a first lifting part 311, a second lifting part 312, and a first connecting part 314; the first lifting part 311 and the second lifting part 312 are respectively fixedly connected to one end face of the first connecting part 314 along the thickness direction; the first lifting part 311 and the second lifting part 312 are spaced apart; the thickness of the first lifting part 311 gradually increases from one end near the second lifting part 312 to one end away from the second lifting part 312; the thickness of the second lifting part 312 gradually increases from one end near the first lifting part 311 to one end away from the first lifting part 311; the first screw tube 216, the second lead screw 217, and the third lead screw 218 are respectively connected to one end of the first connecting part 314 along the height direction away from the first lifting part 311. The second lifting unit 320 includes a fourth lifting part 321, a fifth lifting part 322, and a second connecting part 324. The fourth lifting part 321 and the fifth lifting part 322 are respectively fixedly connected to one end face of the second connecting part 324 along the thickness direction. The fourth lifting part 321 and the fifth lifting part 322 are spaced apart. The thickness of the fourth lifting part 321 gradually increases from one end close to the fifth lifting part 322 to one end away from the fifth lifting part 322. The thickness of the fifth lifting part 322 gradually increases from one end close to the fourth lifting part 321 to one end away from the fourth lifting part 321. The second screw tube 226, the fifth lead screw 227, and the sixth lead screw 228 are respectively connected to one end of the second connecting part 324 along the height direction away from the fourth lifting part 321.

[0034] In this embodiment, since the first lifting part 311, the second lifting part 312, the fourth lifting part 321, and the fifth lifting part 322 are inclined, it can be imagined that in some cases, in order to facilitate the aircraft's landing on the water, the outer surface of the float usually needs to be set with a certain curvature. In this way, the first lifting part 311, the second lifting part 312, the fourth lifting part 321, and the fifth lifting part 322 can fix the float relatively stably, so that the float does not shake as much as possible during the installation process. In this embodiment, in order to avoid the first lifting part 311, the second lifting part 312, the fourth lifting part 321, and the fifth lifting part 322 damaging the float during the lifting process, the material of each lifting part can be selectively selected to be a material with a certain plasticity or elasticity, such as rubber or plastic material with a certain hardness.

[0035] In some embodiments of this utility model, such as Figure 1 , Figure 2As shown, the first lifting unit 310 further includes a third lifting part 313; the third lifting part 313 is fixedly connected to the first connecting part 314 at an end face away from the first screw tube 216 in the height direction; the third lifting part 313 is located between the first lifting part 311 and the second lifting part 312; the thickness of the third lifting part 313 is less than the thickness of the first lifting part 311 and the thickness of the second lifting part 312; the first lifting part 311 and the second lifting part 312 are respectively spaced apart from the third lifting part 313;

[0036] The second lifting unit 320 further includes a sixth lifting part 323; the sixth lifting part 323 is fixedly connected to the second connecting part 324 at the end face away from the second screw tube 226 in the height direction; the sixth lifting part 323 is located between the fourth lifting part 321 and the fifth lifting part 322; the thickness of the sixth lifting part 323 is less than the thickness of the fourth lifting part 321 and the thickness of the fifth lifting part 322; the fourth lifting part 321 and the fifth lifting part 322 are respectively spaced apart from the sixth lifting part 323.

[0037] In this embodiment, by providing the third lifting part 313 and the sixth lifting part 323, the buoy can be supported in some situations. It is conceivable that in some cases the buoy may come into contact with the first connecting part 314 or the second connecting part 324. Since the first connecting part 314 and the second connecting part 324 are mostly made of hard materials, by providing the first lifting part 313 and the sixth lifting part 323, the buoy can be supported while also avoiding being scratched by the first connecting part 314 or the second connecting part 324 as much as possible. In this embodiment, the materials of the third lifting part 313 and the sixth lifting part 323 are preferably rubber or plastic with a certain degree of plasticity or elasticity.

[0038] In some embodiments of this utility model, such as Figure 1 , Figure 2 As shown, the first lifting unit 310 further includes a plurality of first anti-slip protrusions 315; the second lifting unit 320 further includes a plurality of second anti-slip protrusions 325; the first anti-slip protrusions 315 are respectively fixedly connected to the end face of the first lifting part 311 away from the first connecting part 314, the end face of the second lifting part 312 away from the first connecting part 314, and the end face of the third lifting part 313 away from the first connecting part 314; the second anti-slip protrusions 325 are respectively fixedly connected to the end face of the fourth lifting part 321 away from the second connecting part 324, the end face of the fifth lifting part 322 away from the second connecting part 324, and the end face of the sixth lifting part 323 away from the second connecting part 324.

[0039] In this embodiment, by providing multiple first anti-slip protrusions 315 and second anti-slip protrusions 325, it can be imagined that when the float is assembled with the aircraft, the float may tilt. By providing multiple first anti-slip protrusions 315 and second anti-slip protrusions 325, the friction between the first lifting part 311, the second lifting part 312, the third lifting part 313, the fourth lifting part 321, the fifth lifting part 322, the sixth lifting part 323 and the float can be increased, thereby preventing the float from slipping.

[0040] In some embodiments of this utility model, the first lifting part 311, the second lifting part 312, the third lifting part 313, the fourth lifting part 321, the fifth lifting part 322, the sixth lifting part 323, the first anti-slip protrusion 315, and the second anti-slip protrusion 325 are made of soft material; the first connecting part 314 and the second connecting part 324 are made of hard material.

[0041] In some embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the support assembly 100 includes a support frame 110, multiple casters 120, and multiple adjustable feet 130; the first drive rod 212, the second drive rod 222, the first lead screw 215, and the fourth lead screw 225 are rotatably connected to the support frame 110; the second lead screw 217, the third lead screw 218, the fifth lead screw 227, and the sixth lead screw 228 are movably connected to the support frame 110; the first spacer nut 219 and the second spacer nut 229 abut against the support frame 110; the fixed end of the caster 120 is fixedly connected to the support frame 110; and the adjustable feet 130 are threadedly connected to the support frame 110.

[0042] The support frame 110 includes a frame body 111, a first support tube 112, a second support tube 113, a third support tube 114, a fourth support tube 115, a first support, and a second support. One end of the first support tube 112 along its axial direction, one end of the second support tube 113 along its axial direction, one end of the third support tube 114 along its axial direction, and one end of the fourth support tube 115 along its axial direction are respectively fixedly connected to the upper end of the frame body 111 in the height direction.
