Description

Technical Field

[0001] This utility model belongs to the field of aircraft wheel maintenance technology, and specifically relates to an aircraft wheel maintenance bracket. Background Technology

[0002] Aircraft landing gear is a crucial component of the aircraft landing gear system, bearing all the loads during parking, taxiing, takeoff, and landing. Because aircraft landing gear experiences enormous loads during landing, and the tires rub intensely against the runway, aircraft tires are considered consumable items, making tire replacement a routine line maintenance procedure. Replacing a tire requires removing the entire landing gear from the aircraft.

[0003] A search revealed a Chinese utility model patent application with patent publication number CN222973634U, which discloses an aircraft wheel maintenance bracket. The bracket includes a lower housing, an upper housing fixedly connected to the upper outer wall of the lower housing, and a support frame slidably disposed within the upper housing. A first bidirectional screw is rotatably disposed between the inner walls of both sides of the support frame. Two symmetrically distributed first movable blocks are threaded onto the wall of the first bidirectional screw. Through the provided movable components, when the device needs to be moved, the casters extend out of the lower housing to support it for movement. When maintaining the wheel, the casters can retract into the lower housing, allowing the entire lower housing to touch the ground. A lifting component allows the support frame to be raised and lowered. When disassembling the wheel, the support frame rises, and the support plate holds the wheel. This method makes it easier to detach the wheel from the axle.

[0004] Regarding the aforementioned technologies, due to the large size of the aircraft wheel, it will generate a certain amount of inertia during operation. When inertia occurs, the aircraft wheel may wobble, and this wobble will cause many uncertainties. When the support bracket and limit block are in contact with the concave surface of the aircraft tire edge, the fixed clamping of the aircraft wheel is not ideal. Therefore, it is urgent to design an aircraft wheel maintenance bracket to deal with these problems. Utility Model Content

[0014] The beneficial effects are:

[0015] This utility model discloses an aircraft wheel maintenance bracket. Through a movable clamping mechanism, a power motor drives a second lead screw to rotate, causing a second moving platform to move relative to or towards each other. Simultaneously, the clamping ring, electric telescopic rod, and arc-shaped clamping plate move laterally relative to or towards each other. When the wheel body is placed on the support platform, the wheel body is longitudinally positioned by a longitudinal positioning component. The wheel body is clamped by the opposing moving clamping ring, electric telescopic rod, and arc-shaped clamping plate. Simultaneously, the electric telescopic rod pushes the arc-shaped clamping plate to laterally clamp the outer surface of the wheel body, ensuring effective clamping and increasing wheel body fixation, thus improving transfer efficiency. This avoids the risk of accidental injury that can easily occur during wheel transfer, making it convenient to use and highly practical. Attached Figure Description

[0024] Reference Figure 1-4 One embodiment of this utility model is an aircraft wheel maintenance bracket, which includes a base 1, a lifting mechanism 2 above the base 1, and a movable clamping mechanism 3 above the lifting mechanism 2.

[0025] In this embodiment: the lifting mechanism 2 includes a vertical plate 201 fixedly disposed on the front and rear sides above the base 1. A first lead screw 202 is rotatably mounted on the vertical plate 201. A drive motor 205 is fixedly mounted on one end of the first lead screw 202.

Movable wheels 206 are fixedly installed on the front and rear sides below the base 1. The movable wheels 206 are universal type with plastic double brakes. The two connecting rods 208 are arranged in a V-shape.

[0026] In this embodiment: the movable clamping mechanism 3 includes a support platform 301 fixedly disposed above the lifting mechanism 2. A bearing support platform 302 is horizontally fixedly installed at the middle of the upper part of the support platform 301. A first groove platform 303 is horizontally fixedly installed on the front and rear sides of the bearing support platform 302. A first I-beam 304 is slidably installed in the first groove platform 303. Second groove platforms 308 are fixedly installed at both ends of the bearing support platform 302. A second I-beam 3081 is slidably disposed in the second groove platform 308. The first I-beam 304 and the second I-beam 308... A second L-shaped platform 3041 is fixedly installed between the two sections. A second lead screw 305 is horizontally rotatably installed below the support platform 302. A power motor 306 is fixedly installed at one end of the second lead screw 305. A second moving platform 307 is threadedly connected to the outer surface of the second lead screw 305. A clamping ring 309 is fixedly installed above the second I-shaped platform 3081. An electric telescopic rod 310 is fixedly installed on the clamping ring 309. There are two sets of electric telescopic rods 310 fixedly installed on the clamping ring 309, and the two sets of electric telescopic rods 310 are electrically connected. An arc-shaped clamping plate 311 is fixedly provided at the telescopic end of the electric telescopic rod 310, and an anti-slip material is fixedly installed on the arc-shaped clamping plate 311. When the clamping ring 309 on the second I-beam 3081 moves relative to the wheel, the electric telescopic rod 310 pushes the arc-shaped clamping plate 311 towards the outer wall of the wheel body 314, so that the inner side of the arc-shaped clamping plate 311 contacts the outer ring surface of the wheel body 314 and squeezes it. This force can achieve the clamping function of the wheel body 314. This clamping method can simultaneously handle aircraft wheel bodies 314 of various sizes. A longitudinal positioning component is vertically fixed on the rear side of the support platform 302. The wheel body 314 is clamped and installed on the support platform 302 and the arc-shaped clamping plate 311. The longitudinal positioning component includes a long strip plate 312 vertically set on the rear side of the support platform 302. A movable positioning rod 313 is movably installed on the long strip plate 312. A first positive thread is fixedly provided on the outer surface of one end of the second lead screw 305, and a first negative thread is fixedly provided on the outer surface of the other end of the second lead screw 305. The long strip 312 is provided with a positioning through hole, which is used to cooperate with the movable positioning rod 313 to longitudinally position the wheel body 314. The movable positioning rod 313 is provided with a connecting thread, and a nut is rotatably installed on the connecting thread.

[0027] Working principle: In use, the maintenance bracket is first moved to the designated position by the moving wheels 206, and the moving wheels 206 are double-brake positioned. The drive motor 205 is started to drive the first lead screw 202 to rotate, which in turn drives the first moving platform 203 to move relative to it, drives the connecting rod 208 to move, and pushes the mounting platform 211 and the moving clamping mechanism 3 to rise. The first L-shaped plate 210 slides on the outer surface of the limiting upright 207. When the bottom wall of the bearing platform 302 contacts the lower outer surface of the wheel body 314, the nut fixing the wheel body 314 is removed using a tool. After the wheel body 314 is disassembled using an external disassembly tool, the movable positioning rod 313 is longitudinally installed on the wheel body 314 and is connected to the long strip plate 3. 12. The longitudinal fixation is performed, and the power motor 306 is started to drive the second lead screw 305 to rotate, which in turn drives the second moving platform 307 to move towards each other. At the same time, it drives the first I-beam platform 304 in the first groove platform 303 to move. The second I-beam platform 3081 is driven to move in the second groove platform 308 through the second L-shaped platform 3041. This causes the clamping ring 309, electric telescopic rod 310 and arc-shaped clamping plate 311 fixed on the second I-beam platform 3081 to move towards each other. The electric telescopic rod 310 is started to push the arc-shaped clamping plate 311, so that the inner side of the arc-shaped clamping plate 311 contacts the outer ring surface of the wheel body 314 and squeezes it. Through this force, the clamping function of the wheel body 314 can be realized. During the transfer and disassembly process, the force is not easy to slip, which improves the stability.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
