Detailed Implementation

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] Example 1: This example provides an aircraft maintenance tooling platform, see [link / reference]. Figures 1 to 12Specifically, this includes the maintenance bay 100. As the main framework of the entire aircraft maintenance tooling platform, the maintenance bay 100 provides an enclosed space for maintenance operations and also supports the installation and operation of various components. It is the basic carrier for all functions. The maintenance bay 100 has a trapezoidal notch 111 on the top, a rectangular notch 112 on the front, and a rectangular opening 113 on the bottom. The trapezoidal notch 111, the rectangular notch 112, and the rectangular opening 113 are sequentially arranged to facilitate the entry and exit of the landing gear 101 and aircraft wheels 102 into the maintenance bay 100. The path is unobstructed. Load-bearing brackets 106 are fixed at the bottom corners of both sides of the maintenance house 100. Load-bearing rollers 108 are rotatably installed at the bottom of each load-bearing bracket 106. A landing gear 101 is inserted into the trapezoidal notch 111. A pair of aircraft wheels 102 are rotatably installed at the bottom end of the landing gear 101. The load-bearing brackets 106 bear the weight of the maintenance house 100 and its internal components, and play a load-bearing support role. The load-bearing rollers 108 reduce the friction when the maintenance house 100 moves by rolling, making it easier for the maintenance house 100 to move as a whole to the position of the aircraft wheels 102.

[0033] A pair of symmetrically distributed bent swing arms 204 are hinged to both sides of the trapezoidal notch 111, each equipped with an elastic sealing mechanism. The elastic sealing mechanism includes a crescent-shaped elastic band 205. The middle part of the bent swing arm 204 is bent into a semi-circular ring, and a crescent-shaped elastic band 205 is fixed inside the semi-circular ring. The pair of crescent-shaped elastic bands 205 close relative to each other and abut against the landing gear 101. The crescent-shaped elastic bands 205 utilize elastic deformation to tightly adhere to the landing gear 101, enhancing the fixing effect on the landing gear 101 while avoiding rigid contact damage to the landing gear 101. Each bent swing arm 204 has a fixed outer edge... There is a cover plate 206, and a pair of cover plates 206 are closed and cover the trapezoidal notch 111. The cover plate 206 is used to close the trapezoidal notch 111, reduce external interference, and form a relatively sealed maintenance space with other components. The maintenance room 100 is connected to a pair of bent swing arms 204 through a transmission mechanism. A pair of symmetrical sliding doors 300 are slidably provided on both sides of the rectangular notch 112. Each sliding door 300 is connected to the maintenance room 100 through a sliding mechanism. The sliding door 300 is used to close the front passage of the maintenance room 100 and form a sealed maintenance space with other components.

[0034] It should be noted that in this embodiment, a trapezoidal channel steel plate 107 is rotatably mounted on the bottom end of the load-bearing bracket 106. A pair of load-bearing swing arms 109 are hinged to the bottom end of the trapezoidal channel steel plate 107, and a load-bearing roller 108 is rotatably mounted between the bottom ends of the pair of load-bearing swing arms 109. A hydraulic telescopic cylinder 110 is hinged to the middle of each load-bearing swing arm 109. The end of the hydraulic telescopic rod of each hydraulic telescopic cylinder 110 is movably hinged to the trapezoidal channel steel plate 107. The hydraulic telescopic cylinder 110 drives the load-bearing swing arm 109 to swing along the trapezoidal channel steel plate 107 through the extension and retraction of the hydraulic telescopic rod, thereby adjusting the height of the maintenance shelter 100. The bottom surface of the maintenance room 100 can be fixed in contact with the ground; a pair of symmetrically distributed heating plates 104 are fixed on the two side walls inside the maintenance room 100. Each heating plate 104 is fixed with several evenly distributed heat-conducting protrusions 105. A pair of symmetrically distributed first through holes are opened on the two side walls of the maintenance room 100. A heating module 103 is fixedly installed inside each first through hole. Each heating module 103 is electrically connected to the heating plate 104 on the same side by wire. The heating module 103 provides a heat source for the heating plate 104, drives the heating plate 104 to generate heat, and dissipates it to the maintenance space through the heat-conducting protrusions 105 to maintain the maintenance environment temperature.

[0035] In the specific implementation process, such as Figure 8 , Figure 9 and Figure 10 As shown, a pair of L-shaped connecting plates 401 symmetrically distributed vertically are fixed to the rear side wall of the maintenance house 100. A horizontally distributed fixing plate 400 is fixed between the pair of L-shaped connecting plates 401. Fixed swing arms 403 are rotatably installed at the four corners of the fixing plate 400. A roller shaft is rotatably inserted at the outer end of each fixed swing arm 403. A concentrically fixed roller 404 is sleeved at the outer end of each roller shaft. Each roller 404 abuts against the aircraft wheel 102 on the corresponding side. The L-shaped connecting plate 401 provides installation support points for the fixing plate 400. The fixing plate 400 serves as the installation base for components such as the fixed swing arm 403 and the third motor 408, bearing the weight and movement of the relevant components. The fixed swing arm 403 swings under power drive, causing the roller 404 to press against the aircraft wheel 102, thereby fixing the aircraft wheel 102 and avoiding rigid contact damage to the surface of the aircraft wheel 102.

[0036] At each of the four corners of the fixed plate 400, a through-type fixed shaft 402 is rotatably inserted. The front end of each fixed shaft 402 is fixedly connected to the fixed swing arm 403 on the corresponding side, and the rear end of each fixed shaft 402 is fixedly connected to a fixed connecting rod 410. Each fixed connecting rod 410 is parallel to the fixed swing arm 403 on the corresponding side. A pair of symmetrically distributed T-shaped slide rails 405 are fixedly installed on both sides of the back of the fixed plate 400. A U-shaped sliding plate is slidably fitted in the middle of each T-shaped slide rail 405. 406, T-shaped slide rail 405 provides a sliding track for U-shaped slide plate 406, restricts its movement direction, and ensures smooth sliding. Each U-shaped slide plate 406 has a pair of symmetrically distributed driven links 411 hinged at both ends. The outer end of each driven link 411 is movably hinged to the outer end of the fixed link 410 on the corresponding side. The U-shaped slide plate 406 drives the fixed link 410 to move through the driven link 411. The fixed link 410 drives the fixed shaft 402 and the fixed swing arm 403 to swing.

[0037] A third through hole is provided in the middle of the fixed plate 400. A third motor 408 with the output end facing backward is fixedly installed inside the third through hole. A double-headed connecting rod 409 is fixedly provided at the end of the motor shaft of the third motor 408. A pair of staggered hinged connecting rods 407 are hinged at both ends of the double-headed connecting rod 409. The outer end of each hinged connecting rod 407 is movably hinged to the middle of the U-shaped sliding plate 406 on the same side. The third motor 408 drives the double-headed connecting rod 409 to rotate through the motor shaft. The double-headed connecting rod 409 transmits power to the hinged connecting rod 407. The hinged connecting rod 407 drives the U-shaped sliding plate 406 to slide along the T-shaped slide rail 405.

[0038] The working principle of this embodiment is as follows: First, push the load-bearing roller 108 to move the maintenance house 100 as a whole to the location of each aircraft wheel 102. Then, push the maintenance house 100 towards the landing gear 101 and the aircraft wheels 102, so that the landing gear 101 and the aircraft wheels 102 enter the interior of the maintenance house 100 through the trapezoidal notch 111, the rectangular notch 112 and the rectangular opening 113.

[0039] Next, driven by four pairs of hydraulic telescopic cylinders 110, their hydraulic telescopic rods shorten synchronously, causing the trapezoidal channel steel plate 107 to fall along the hinge direction of the load-bearing swing arm 109, and then synchronously causing the load-bearing bracket 106 and the maintenance house 100 to fall as a whole until the bottom surface of the maintenance house 100 contacts the ground. At this time, maintenance personnel can enter the maintenance house 100 to prepare for maintenance work.

[0040] Subsequently, driven by the transmission mechanism, a pair of bending swing arms 204 rotate, causing a pair of cover plates 206 to close relative to each other, covering the trapezoidal notch 111; at the same time, under the action of the sliding mechanism, a pair of sliding doors 300 slide on both sides of the rectangular notch 112 and close relative to each other; in this way, the maintenance room 100 is in a closed state, forming a relatively sealed maintenance space, which can effectively isolate external interference such as water, electricity and light.

[0041] During maintenance, if the ambient temperature is low, the heating module 103 can be activated. It is connected to the heating plate 104 via wires, which generates heat in the heating plate 104. The heat is dissipated into the maintenance space through several evenly distributed heat-conducting protrusions 105 on the heating plate 104, thereby maintaining a comfortable working temperature in the maintenance space and preventing the hands of maintenance personnel from being frozen due to the low temperature of the landing gear 101, aircraft wheels 102 and their connecting components, which would affect maintenance operations.

[0042] In addition, to stabilize the aircraft wheel 102, the third motor 408 is started. Its motor shaft drives the double-headed connecting rod 409 to rotate. Under the hinge action of the double-headed connecting rod 409 and a pair of hinged connecting rods 407, the U-shaped slide plate 406 is driven to slide inward along the T-shaped slide rail 405. The U-shaped slide plate 406 drives the fixed connecting rod 410, the fixed shaft 402 and the fixed swing arm 403 to swing along the axis of the fixed shaft 402 through the driven connecting rod 411. This causes the roller 404 on the outer end roller shaft of each fixed swing arm 403 to abut against the corresponding side of the aircraft wheel 102, thereby clamping and fixing the aircraft wheel 102. Then, the maintenance personnel can safely carry out maintenance work on the aircraft wheel 102 in the maintenance space.

[0043] Example 2: This example, based on Example 1, adds a specific transmission mechanism, solving the problem of driving and stabilizing the movement of the pair of bending swing arms 204 and the cover plate 206. It also includes:

[0044] In the specific implementation process, such as Figure 4 and Figure 5 As shown, the transmission mechanism includes a worm gear 201. A pair of swing shafts 200 are rotatably inserted on the top surface of the maintenance house 100. The rear end of each bent swing arm 204 is fixed to the middle of the swing shaft 200 on the same side. The top end of each swing shaft 200 is fitted with a concentrically fixed worm gear 201. A fixed bracket is fixed to the rear side of the top surface of the maintenance house 100. A first motor 202 with the output end facing forward is fixedly installed inside the fixed bracket. A worm 203 is fixed to the end of the motor shaft of the first motor 202. The worm 203 is located between the pair of worm gears 201 and meshes with the pair of worm gears 201. The first motor 202 provides power to the transmission mechanism and drives the worm 203 to rotate through the motor shaft. The worm 203 transmits power to the worm gears 201, thereby driving the swing shafts 200 and the bent swing arms 204 to swing synchronously.

[0045] A pair of symmetrically distributed first arc-shaped grooves 209 are provided on both sides of the rear end of the trapezoidal notch 111. A first pin 207 is inserted at the corner of the rear end of the cover plate 206. The bottom end of the first pin 207 is slidably inserted into the first arc-shaped groove 209 on the same side. A pair of symmetrically distributed second arc-shaped grooves 210 are provided on both sides of the front end of the trapezoidal notch 111. A second pin 208 is inserted at the corner of the front end of the cover plate 206. The bottom end of the second pin 208 is slidably inserted into the second arc-shaped groove 210 on the same side. The first pin 207 and the second pin 208 play a guiding role when the cover plate 206 moves, ensuring that it moves stably along the preset trajectory.

[0046] The working principle of this embodiment is as follows: Under the drive of the first motor 202, the motor shaft drives the worm 203 to rotate synchronously. Since the worm 203 is located between and meshes with a pair of worm wheels 201, it will mesh and drive the pair of worm wheels 201 to rotate relative to each other. When the worm wheels 201 rotate, they will drive the swing shaft 200 on the same side to rotate accordingly, thereby causing the bent swing arm 204 fixed in the middle of the swing shaft 200 and the cover plate 206 connected to the bent swing arm 204 to move inward.

[0047] During this process, the first pin 207 at the rear corner of the cover plate 206 slides along the first arc grooves 209 on both sides of the rear end of the trapezoidal notch 111, while the second pin 208 at the front corner of the cover plate 206 slides along the second arc grooves 210 on both sides of the front end of the trapezoidal notch 111. Through this movement, a pair of bent swing arms 204 achieve relative closure, causing their respective crescent-shaped elastic bands 205 to abut against both sides of the landing gear 101, and simultaneously causing a pair of cover plates 206 to close relative to each other and cover the trapezoidal notch 111.

[0048] Example 3: Based on Example 2, this example adds a specific sliding mechanism and related structures for the sliding door 300, solving the problem of driving and stably sliding the sliding door 300 to close the rectangular notch 112. It also includes:

[0049] In the specific implementation process, such as Figure 6 and Figure 7 As shown, two pairs of symmetrically distributed T-shaped grooves 303 are provided on both sides of the rectangular notch 112. A pair of vertically symmetrically distributed T-shaped slide plates 301 are fixed on the back of the sliding door 300. Each T-shaped slide plate 301 is slidably engaged in the T-shaped groove 303 on the same side. Vertically distributed elliptical pin holes 302 are provided on the outer side of the sliding door 300. The T-shaped grooves 303 provide sliding tracks for the T-shaped slide plates 301, restrict the movement direction of the sliding door 300, and ensure its stable sliding.

[0050] The sliding mechanism includes a turntable 305 and a third pin 306. A pair of symmetrically distributed circular grooves are provided on both sides of the rectangular notch 112. Each circular groove has a second through hole inside. A second motor 304 with its output end facing forward is fixedly installed inside each second through hole. The motor shaft end of each second motor 304 is fitted with a turntable 305 that is concentrically fixed. The front of each turntable 305 is fixed with an eccentrically distributed third pin 306. The outer end of each third pin 306 is slidably fitted in an elliptical pin hole 302 on the same side. The second motor 304 provides power to the sliding mechanism and drives the turntable 305 to rotate through the motor shaft. The third pin 306 on it drives the sliding door 300 to slide through the eccentric motion.

[0051] The working principle of this embodiment is as follows: A pair of second motors 304 are started and controlled to rotate in opposite directions. The motor shafts of the second motors 304 drive the turntable 305 to rotate in the circular grooves on both sides of the rectangular notch 112. Since the outer end of the third pin 306 eccentrically distributed on the turntable 305 slides in the elliptical pin hole 302 on the outer side of the sliding door 300, the two form a limiting effect, thereby driving the sliding door 300 and the pair of T-shaped sliding plates 301 fixed on the back to slide inward along the T-shaped sliding grooves 303 on both sides of the rectangular notch 112, so that the pair of sliding doors 300 are relatively translated and closed, just covering the rectangular notch 112.

[0052] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
