[0021] Generally speaking, in the brake inertia platform of this embodiment, when the mounting seat 310 and / or the scraper 320 are in the first position, the scraper 320 can abut against the outer peripheral surface of the inertia wheel 200, so that as the inertia wheel 200 rotates, the scraper 320 can scrape off the tire skin adhered to the outer peripheral surface of the inertia wheel 200; when the mounting seat 310 and / or the scraper 320 are in the second position, the scraper 320 is separated from the contact with the inertia wheel 200, so as not to affect the normal rotation of the inertia wheel 200.

[0022] refer to Figure 1 As shown, the brake inertia platform of this embodiment further includes an inertia wheel driving device 400 for driving the inertia wheel 200 to rotate. In terms of specific structure, the inertia wheel driving device 400 includes a rotational power output unit 410, a torque sensor 420 and an inertia wheel shaft 430, wherein the rotational power output unit 410 is arranged on the base 100, one end of the torque sensor 420 is coaxial with and fixedly connected to the output shaft of the rotational power output unit 410, and the other end is coaxial with and fixedly connected to the inertia wheel shaft 430, the aforementioned inertia wheel 200 is fixedly sleeved on the inertia wheel shaft 430, and in this embodiment, the inertia wheel driving device 400 further includes an encoder for measuring the rotation speed of the inertia wheel shaft 430.

[0023] Based on the above structure, the output shaft of the rotary power output unit 410 can drive the inertia wheel shaft 430 to rotate through the torque sensor 420, thereby driving the inertia wheel 200 to rotate, so as to test the landing gear 700 by making the wheel 710 contact the rotating inertia wheel 200. In this embodiment, the rotary power output unit 410 is a motor, and in some embodiments, it can also be a hydraulic motor. The torque sensor 420 and the encoder can adopt existing products, and their structures and working principles are not repeated here.

In some embodiments, the first linear power output unit 510 may also be a pneumatic cylinder or an electric cylinder. Based on the above structure, when the telescopic rod of the hydraulic cylinder is extended, the pull rod 520 can drive the rotating shaft 530 to rotate around the axis of the rotating shaft 530 itself, and the rotation of the rotating shaft 530 will drive each brake pad 540 to rotate to abut against the outer peripheral surface of the inertia wheel 200, so that the inertia wheel 200 stops rotating through the friction between each brake pad 540 and the inertia wheel 200. When the telescopic rod of the hydraulic lever is shortened, the pull rod 520 can drive the rotating shaft 530 to rotate in the opposite direction, and the rotation of the rotating shaft 530 will drive each brake pad 540 away from the outer peripheral surface of the inertia wheel 200. In this state, the brake pad 540 will not affect the rotation of the inertia wheel 200.

[0026] In this embodiment, reference Figure 1 and Figure 3 As shown, a tension spring 550 is provided between the pull rod 520 and the base 100, and the tension spring 550 applies a tension force to the pull rod 520, and the tension force can drive the rotating shaft 530 to rotate in a direction to make the brake pad 540 away from the outer peripheral surface of the inertia wheel 200. By providing the tension spring 550, the brake pad 540 can be better separated from the contact with the inertia wheel 200.

In terms of specific structure, the landing gear drive device 600 includes a second linear power output unit 610 and a slide 620 arranged on the base 100. The slide 620 is provided with a landing gear mounting portion for mounting the landing gear 700, and the slide 620 can be driven by the second linear power output unit 610 to slide, so that the wheel 710 on the landing gear 700 abuts against the outer peripheral surface of the inertia wheel 200, or moves away from the inertia wheel 200.

[0028] refer to Figure 1As shown, two parallel and spaced guide rails 110 are fixedly provided on the base 100, and a slider 621 adapted to the two guide rails 110 is fixedly provided on the slide 620. The second linear power output unit 610 is a hydraulic cylinder, whose cylinder is connected to the base 100, and the telescopic rod is connected to the slide 620, so that the slide 620 is driven to move along the length direction of the guide rail 110 by the telescopic rod of the hydraulic cylinder, so that the wheel 710 contacts the inertia wheel 200, or moves away from the inertia wheel 200. In this embodiment, a pressure sensor is provided between the second linear power output unit 610 and the slide 620, and the pressure sensor is used to measure the pressure applied by the second linear power output unit 610 to the pressure sensor, that is, to measure the load applied to the landing gear 700. It should be noted that the structure of the landing gear mounting portion on the slide 620 for mounting the landing gear 700 can refer to the prior art, and it will not be described in detail here.

[0029] refer to Figure 1 and Figure 2 As shown, in this embodiment, the mounting seat 310 is rotatably arranged on the base 100, and a first elastic member 330 is arranged between the mounting seat 310 and the base 100, and the first elastic member 330 applies an elastic force to the mounting seat 310 to rotate the mounting seat 310 to the second position. By providing the first elastic member 330, when in use, the staff pushes the mounting seat 310 to rotate, so that the tire scraping member 320 on the mounting seat 310 abuts against the outer peripheral surface of the inertia wheel 200, so that when the inertia wheel 200 rotates, the tire scraping member 320 scrapes off the tire skin adhered to the outer peripheral surface of the inertia wheel 200; when the staff no longer pushes the mounting seat 310, the mounting seat 310 is driven by the first elastic member 330 to rotate until the tire scraping member 320 is separated from the contact with the inertia wheel 200. That is, in this embodiment, the scraper 320 is driven to abut against the outer circumference of the inertia wheel 200 or to break away from the contact with the inertia wheel 200 by the rotation of the mounting seat 310 between the first position and the second position.

[0030] refer to Figure 2 As shown, the first elastic member 330 of this embodiment is a tension spring connected between the base 100 and the mounting seat 310. In some embodiments, the first elastic member 330 can also be a torsion spring or the like.

[0031] In some embodiments, Figure 4As shown, a hydraulic drive cylinder 340 is provided between the mounting seat 310 and the base 100, and the fixed end of the hydraulic drive cylinder 340 is hinged to the base 100, and the telescopic end is hinged to the mounting seat 310. The extension or contraction of the telescopic end of the hydraulic drive cylinder 340 can drive the mounting seat 310 to rotate, so that the scraper 320 abuts against the outer peripheral surface of the inertia wheel 200, or the scraper 320 is separated from the contact with the inertia wheel 200. By providing the hydraulic cylinder to replace the staff to rotate the mounting seat 310, the labor intensity of the staff can be reduced.

[0032] refer to Figure 4 As shown, the scraper 320 of this embodiment includes a fixed plate 321 fixed on the mounting seat 310, and a scraper slidably arranged on the fixed plate 321. For the convenience of description, this embodiment is called a first scraper 322. A second elastic member 323 is provided between the first scraper 322 and the fixed plate 321. The second elastic member 323 applies an elastic thrust to the first scraper 322 to make the first scraper 322 approach the outer peripheral surface of the inertia wheel 200.

[0033] By providing the second elastic member 323 to support the first scraper 322, it is possible to avoid hard contact between the first scraper 322 and the inertia wheel 200, thereby reducing the risk of the first scraper 322 scratching the outer peripheral surface of the inertia wheel 200. In this embodiment, the second elastic member 323 is a spring, and obviously, the second elastic member 323 can also be other elastic components.

[0034] In this embodiment, reference Figure 5 and Figure 6 As shown, a driving unit 350 and a second scraper 360 connected to the output end of the driving unit 350 are also provided on the mounting seat 310. The second scraper 360 can be driven by the driving unit 350 to reciprocate along the axial direction of the inertia wheel 200; and blades 361 inclined relative to the axial direction of the inertia wheel 200 are respectively provided on two opposite sides of the second scraper 360. When the mounting seat 310 rotates to the first position, the two blades 361 respectively abut against the outer peripheral surface of the inertia wheel 200.

[0035] By providing a second scraper 360 that can reciprocate along the axial direction of the inertia wheel 200, and making the blade 361 of the second scraper 360 inclined relative to the axial direction of the inertia wheel 200, when the second scraper 360 contacts the tire skin on the outer peripheral surface of the inertia wheel 200, it can obliquely enter between the tire skin and the inertia wheel 200 from the edge of the tire skin, so that the blade 361 can be inserted between the tire skin and the inertia wheel 200 with less force, that is, the second scraper 360 can better scrape the tire skin on the outer peripheral surface of the inertia wheel 200. By providing blades 361 on both opposite sides of the second scraper 360, the tire skin on the outer peripheral surface of the inertia wheel 200 can be scraped when the second scraper 360 moves in both directions.

[0036] For specific structure, refer to Figure 5 and Figure 6 As shown, the driving unit 350 includes a driven wheel 351, a transmission unit, a reciprocating screw 352 and a sliding block 353. The driven wheel 351 and the reciprocating screw 352 are rotatably arranged on the mounting seat 310, respectively, the transmission unit is arranged between the driven wheel 351 and the reciprocating screw 352, and the sliding block 353 is screwed with the reciprocating screw 352. When the mounting seat 310 rotates to the first position, the driven wheel 351 abuts against the outer peripheral surface of the inertia wheel 200 and can be driven to rotate by the inertia wheel 200. After the transmission of the transmission unit, the rotation of the driven wheel 351 can drive the reciprocating screw 352 to rotate, and the sliding block 353 can reciprocate along the axial direction of the reciprocating screw 352. The second scraper 360 is arranged on the sliding block 353.

[0037] The transmission unit includes a first synchronous wheel coaxially and fixedly connected to the driven wheel 351, a second synchronous wheel coaxially and fixedly connected to the reciprocating screw 352, and a synchronous belt arranged between the second synchronous wheel and the first synchronous wheel. In some embodiments, the transmission unit may also include a first gear coaxially and fixedly connected to the driven wheel 351, and a second gear coaxially and fixedly connected to the reciprocating screw 352, the second gear meshing with the first gear.

[0038] Based on the above structure, when the mounting seat 310 is in the first position, the rotation of the inertia wheel 200 drives the driven wheel 351 to rotate through the friction between the driven wheel 351 and the inertia wheel 200, and the rotation of the driven wheel 351 drives the reciprocating screw 352 to rotate through the transmission of the first synchronous wheel and the second synchronous wheel. The sliding block 353 screwed to the reciprocating screw 352 drives the second scraper 360 on the sliding block 353 to reciprocate along the axial direction of the reciprocating screw 352 under the guidance of the guide rod, so that the second scraper 360 scrapes the tire skin on the outer peripheral surface of the inertia wheel 200.

[0039] In some embodiments, a screw is rotatably provided on the mounting seat 310, and a left-handed external thread and a right-handed external thread are provided at intervals on the outer periphery of the screw along the axial direction of the screw, and nut seats are respectively screwed on the left-handed external thread and the right-handed external thread; the scraper 320 includes two scraper plates respectively provided on the two nut seats; as the screw rotates, the two scraper plates can approach and abut against the outer periphery of the inertia wheel 200, or move away from each other and move to both sides of the inertia wheel 200 and away from the outer periphery of the inertia wheel 200. In this embodiment, the mounting seat 310 is fixed, and the scraper 320 can be switched between the first position and the second position, so that the scraper 320 abuts against the outer periphery of the inertia wheel 200, or the scraper 320 is out of contact with the inertia wheel 200.

[0040] Based on the above overall structure, the overall working process of the brake inertia platform of this embodiment is as follows: The motor of the inertia wheel driving device 400 rotates, driving the inertia wheel 200 to rotate, and the speed of the inertia wheel 200 is measured by an encoder, and the speed of the inertia wheel 200 is used to simulate the translation speed of the aircraft landing gear 700 when landing; The hydraulic cylinder of the landing gear drive device 600 moves, pushing the landing gear 700 to contact the inertia wheel 200, so that the inertia wheel 200 and the wheel 710 of the landing gear 700 rotate synchronously, which is used to simulate the speed of the landing gear 700 at the moment of landing. The hydraulic cylinder continuously applies loading force to simulate the process in which the weight of the aircraft is continuously loaded onto the runway during the landing process of the aircraft; The moment the wheel 710 of the landing gear 700 contacts the inertia wheel 200, the brake device 500 is turned on, and the hydraulic cylinder of the brake device 500 is actuated to drive the brake pad 540 to brake the inertia wheel 200, simulating the runway after the aircraft lands to provide the wheel 710 with a corresponding reverse rotation until the wheel 710 stops moving; In the above process, the wheel 710 rotates at a high speed, and the tire skin will adhere to the inertia wheel 200. The tire skin scraping device 300 is used to scrape the tire skin on the inertia wheel 200.
