[0002] The nose landing gear tires of drones need to be frequently disassembled and reassembled during routine maintenance, flight operations, and scheduled inspections. The current disassembly and reassembly methods mainly rely on two operators: one person holds the tire in place, while the other uses a copper hammer and a punch to tap the tire axle or bearing to loosen it.

[0003] This approach has the following drawbacks:

[0004] The impact force is large and can easily damage equipment. The impact of the copper hammer is an instantaneous force that can easily damage the front landing gear hub, bearings, shaft ends and other parts, reducing assembly accuracy and lifespan.

[0005] It requires the cooperation of multiple people, resulting in low efficiency. Disassembly and assembly require the collaboration of two people, making it difficult to meet the high-frequency and high-efficiency support needs when the workload is large or there is a shortage of personnel.

[0006] The disassembly and assembly process is poorly controllable, and the impact force is difficult to control precisely, posing a risk of insufficient or excessive impact.

Detailed Implementation

[0028] like Figures 1 to 7 As shown, a quick-release tool for front landing gear tires includes a support frame 10. A lifting platform assembly 20 is mounted at the front end of the support frame 10, and a mounting bracket 11 is mounted at the rear end. A compression-pull assembly 30 is mounted on the mounting bracket 11. The front end of the compression-pull assembly 30 is correspondingly positioned with the lifting platform assembly 20. In use, the lifting platform assembly 20 supports the front landing gear tire, and its height is adjusted to align the tire's center height with the force axis of the compression-pull assembly 30. During operation, the compression-pull assembly 30 applies axial thrust or pull to the tire axle or hub, enabling rapid axial removal or installation of the tire.

[0029] In practical implementation, the compression and tension assembly 30 includes a compression fixing seat 31, a compression tension rod 32, and a compression button handle 33. The upper end of the mounting bracket 11 is provided with a bracket mounting rod 111, and the rear end of the bracket mounting rod 111 is provided with a fixing seat mounting ring 112. The front end of the compression fixing seat 31 is provided with a fixing seat connecting ring 311, which is located at the rear end of the fixing seat mounting ring 112. The fixing seat connecting ring 311 and the fixing seat mounting ring 112 are fixedly connected by welding, so that the compression fixing seat 31 is securely mounted on the mounting bracket 11. The compression tension rod 32 is movably connected in the compression fixing seat 31, and its front end passes through the fixing seat mounting ring 112 and extends forward, maintaining an axially movable back-and-forth motion. The squeeze button handle 33 is installed at the lower front end of the squeeze mounting base 31. A pusher 34 is connected to the upper end of the squeeze button handle 33. The pusher 34 is connected to the outside of the squeeze tension rod 32, and its inner wall abuts against the squeeze tension rod 32. When the squeeze button handle 33 is pressed, it drives the pusher 34 forward, thereby pushing or pulling the squeeze tension rod 32 to generate a squeezing force. In use, the operator adjusts the lifting platform assembly 20 to correspond to the position of the front landing gear tire axle, and adjusts the mounting bracket 11 to align the squeeze tension rod 32 with the tire axle end. When the operator presses the squeeze button handle 33, the pusher 34 pushes the squeeze tension rod 32 forward, causing the squeeze tension rod 32 to generate a stable squeezing force on the tire bearing, enabling quick disassembly or installation of the tire bearing.

[0030] In practical implementation, the lower end of the compression fixing base 31 is provided with an operating handle 312, and the upper end of the compression button handle 33 is provided with a handle connecting part 331. The handle connecting part 331 is connected to the upper end of the operating handle 312. The upper end of the operating handle 312 is provided with a first handle connecting hole 313, and the lower end of the handle connecting part 331 is provided with a second handle connecting hole 332. The second handle connecting hole 332 is correspondingly provided with the first handle connecting hole 313, and is hinged to the first handle connecting hole 313 by a fastener passing through the second handle connecting hole 332, so that the compression button handle 33 can swing around the axis of the fastener. The lower end of the pressing member 34 has a first pressing connection hole 341, and the upper end of the handle connection part 331 has a second pressing connection hole 333. The second pressing connection hole 333 is correspondingly arranged with the first pressing connection hole 341, and is hinged to the first pressing connection hole 341 by fasteners passing through the second pressing connection hole 333, so that the pressing member 34 and the pressing button handle 33 form a follow-up linkage structure. When the pressing button handle 33 swings, it can drive the pressing member 34 to move synchronously in the back-and-forth direction. In order to make the pressing member 34 automatically return to its original position after the pressing action is completed, a first return spring 35 is connected between the pressing member 34 and the fixed seat connecting ring 311, so that the pressing member 34 automatically returns to its initial position after the external force is lost, improving the continuity of operation. In use, the operator holds the operating handle 312 and presses down on the squeezing button handle 33, causing the handle connection part 331 to rotate around the hinge point formed by the first handle connection hole 313 and the second handle connection hole 332. Simultaneously, the second pushing connection hole 333 drives the first pushing connection hole 341, causing the pushing member 34 to push the squeezing tension rod 32 forward along the squeezing direction, thereby outputting a stable forward squeezing force to achieve rapid disassembly or press-fitting of the front landing gear tire bearing. After releasing the squeezing button handle 33, under the action of the first return spring 35, the pushing member 34 and the squeezing button handle 33 automatically return to their initial positions, facilitating quick re-operation.

[0031] In practical implementation, a limiting clip 36 is connected to the rear end of the compression fixing seat 31. The limiting clip 36 is connected to the rear end of the compression tension rod 32 and is used to position and control the axial position of the compression tension rod 32. A limiting slot 361 is formed in the middle of the limiting clip 36. The limiting slot 361 engages with the side of the compression tension rod 32 to achieve limiting. In use, through the cooperation of the limiting clip 36 and the limiting slot 361, the compression tension rod 32 can achieve graded positioning between different positions. When the operator presses the compression button handle 33 to drive the compression tension rod 32 to move axially, it can pass through each limiting position in sequence, making the tension application process stable and reliable, avoiding accidental slippage of the compression tension rod 32, thereby improving the overall safety and controllability of the operation.

[0032] In practical implementation, a second return spring 37 is connected between the limiting clip 36 and the rear end of the compression fixing seat 31, so that after the limiting clip 36 is disengaged from the current locking position, it can automatically rebound to the initial locking position under the elastic force of the second return spring 37, thereby ensuring the automatic limiting and stable positioning of the compression tension rod 32 during axial movement.

[0033] In practical implementation, the front end of the compression lever 32 is equipped with a compression head 321, which is used to contact the axle end of the front landing gear tire or the outer ring of the bearing during the compression process, and to disassemble or install the bearing through the pushing action. The rear end of the compression lever 32 is equipped with a tension hook 322, which has an arc-shaped structure and a smooth inner transition, so as to facilitate the operator to quickly reset the compression lever 32 by pulling it backward after completing the compression action.

[0034] In practical implementation, the upper end of the bracket mounting rod 111 is respectively provided with a first guide ring 113 and a second guide ring 114. The first guide ring 113 is located at the front end of the second guide ring 114, and the two are arranged at intervals along the axial direction of the bracket mounting rod 111. The front end of the compression tension rod 32 passes through the second guide ring 114 and the first guide ring 113 in sequence, so that the compression tension rod 32 always maintains a stable linear guide during the back and forth movement, without shaking or deviation. Through the dual guide structure of the first guide ring 113 and the second guide ring 114, the force stability of the compression tension rod 32 during the pushing and pulling process can be effectively improved, ensuring that the extrusion head 321 is aligned with the tire axle end or bearing position, avoiding bearing damage or disassembly difficulties caused by eccentric force.

[0035] In practical implementation, a bracket mounting plate 12 is installed at the front end of the bracket frame 10, and the lifting platform assembly 20 is installed on the bracket mounting plate 12. The lifting platform assembly 20 includes a lifting bracket 21 and a lifting platform plate 22. The lifting platform plate 22 is installed at the upper end of the lifting bracket 21, and the lower end of the lifting bracket 21 is installed on the bracket mounting plate 12. In use, the operator can adjust the height structure of the lifting bracket 21 according to the tire height of different models of front landing gear to raise or lower the lifting platform plate 22, so that the upper surface of the lifting platform plate 22 is accurately aligned with the support position of the tire axle end or the outer ring of the tire, ensuring that the extrusion head 321 of the extrusion tension rod 32 can apply force accurately.

[0036] In practical implementation, the lifting support 21 includes an upper support assembly 211 and a lower support assembly 212. A first support connecting rod 213 is movably connected between the upper support assembly 211 and the lower support assembly 212. Fastening components are connected to both ends of the first support connecting rod 213 to stabilize and lock the connection position. First support mounting frames 121 are symmetrically mounted on both sides of the surface of the support mounting plate 12. The lower end of the lower support assembly 212 is movably connected to the first support mounting frame 121 via a second support connecting rod 214, allowing the lower support assembly 212 to change angle around the second support connecting rod 214. Second support mounting frames 221 are symmetrically mounted on both sides of the lower surface of the lifting platform plate 22. The upper end of the upper support assembly 211 is movably connected to the second support mounting frame 221 via a third support connecting rod 215. Fastening components are also provided at both ends of the third support connecting rod 215 to lock the connection position during lifting, ensuring the stability of the lifting platform plate 22 when supporting tires. During use, the operator can adjust the height and angle of the lifting platform plate 22 by adjusting the fastening components of the first bracket connecting rod 213, the second bracket connecting rod 214 and the third bracket connecting rod 215, so that the upper surface of the platform plate 22 is precisely aligned with the front landing gear tire axle end or the outer ring of the tire, ensuring that the extrusion tension assembly 30 is stably stressed and precisely applied when disassembling and assembling the tire bearing.

[0037] In practical implementation, an adjusting sleeve 23 is sleeved on the outer side of the first bracket connecting rod 213. An adjusting screw groove 231 is opened in the middle of the side of the adjusting sleeve 23. An adjusting screw 24 is threadedly connected in the adjusting screw groove 231. A first adjusting slot 122 is opened on the side of the first bracket mounting bracket 121. The two ends of the second bracket connecting rod 214 are respectively connected to the two first adjusting slots 122. A second adjusting slot 222 is opened on the side of the second bracket mounting bracket 221. The two ends of the third bracket connecting rod 215 are respectively connected to the two second adjusting slots 222. Thus, the upper bracket assembly 211 and the lower bracket assembly 212 can achieve relative movement and angle adjustment under the action of the bracket connecting rod. In use, when the adjusting screw 24 is rotated, it engages with the adjusting screw groove 231, bringing the two adjusting sleeves 23 closer together. This causes the upper support assembly 211 and the lower support assembly 212 to rise relative to each other, thereby raising the entire lifting platform assembly 20 and raising the upper surface of the lifting platform plate 22 to the required height, precisely aligning it with the tire axle end or tire outer ring support position. When the adjusting screw 24 is rotated in the opposite direction, the two adjusting sleeves 23 unfold relative to each other, causing the upper support assembly 211 and the lower support assembly 212 to fold relative to each other. This lowers the lifting platform assembly 20, reducing the height of the upper surface of the lifting platform plate 22, thus adapting to and supporting front landing gear tires of different heights. Through this structure, the operator can quickly and accurately control the raising and lowering of the lifting platform assembly 20 via the adjusting screw 24, achieving precise alignment of the lifting platform plate 22 with the tire axle end or tire outer ring, providing stable support and precise force application conditions for the assembly and disassembly of the compression tension assembly 30.

[0038] In practical implementation, the upper support group 211 includes a first upper support rod 211a and a second upper support rod 211b, which are arranged crosswise. The lower support group 212 includes a first lower support rod 212a and a second lower support rod 212b, which are arranged crosswise. In use, the crosswise upper support group 211 and lower support group 212 can form a stable support structure, ensuring that the lifting support 21 has good force balance and stability when the lifting platform plate 22 supports the front landing gear tires, and at the same time, it is convenient to adjust the height through the support connecting rod.

[0039] In summary, this utility model achieves rapid disassembly and installation of the front landing gear tires through the coordinated operation of the lifting platform assembly 20 and the compression and tension assembly 30. The compression and tension assembly 30, through components such as the compression fixing seat 31, compression tension rod 32, compression button handle 33, pushing component 34, and limiting clip 36, forms a stable push-pull linkage structure, capable of applying adjustable axial thrust to the tire axle end or hub, achieving precise disassembly and installation of the tire bearing. The first guide ring 113 and the second guide ring 114 on the bracket mounting rod 111 ensure that the compression and tension rod 32 moves linearly. The return spring 35 and the second return spring 37 enable the automatic reset of the pushing component 34 and the limit clamp 36, making the operation stable and safe. The upper support group 211, the lower support group 212 and the support connecting rod of the lifting bracket 21 ensure that the height of the lifting platform plate is adjustable to adapt to different models of front landing gear tires. The hinged linkage structure between the squeeze button handle 33 and the pushing component 34 makes the operation convenient and the feel smooth. The welding installation of the squeeze fixing seat 31 and the cross rod support of the lifting bracket 21 form a stable force-bearing structure to ensure long-term stability. At the same time, the graded limit and lifting adjustment design improves the applicability and versatility of the tool.
