[0034] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0035] Example 1:

[0036] See Figure 1-5A wide-body aircraft air intake maintenance platform includes a platform base 34. Parallel extended rods 10 are fixed to one end of the platform base 34. A column 18 is fixed to the top of the platform base 34. An inclined ladder structure is installed between the column 18 and the platform base 34. Lifting columns 20 are slidably mounted on the inner wall of the column 18 via multiple guide wheels 19. Ladder bars 22 are arranged between the lifting columns 20. A top platform 24 is fixed to the top of the lifting columns 20. A top frame 23 is fixed between the top platform 24 and the lifting columns 20. A lifting adjustment device is installed between the top platform 24 and the platform base 34. This utility model platform can be used for aircraft air intake maintenance. It can be easily moved to the location requiring maintenance and its height can be easily adjusted according to the maintenance height, enhancing its adaptability, effectively improving maintenance efficiency, and reducing maintenance workload. In practical use, the entire working platform is moved to the location of the aircraft engine's air intake. Then, the lifting and adjusting device is activated according to the height of the air intake. The height of the top platform 34 is adjusted by the lifting and adjusting device. The operators climb to the top platform 24 through the ladder structure and then carry out the corresponding maintenance work on the air intake.

[0037] Furthermore, a diagonal reinforcing rod 14 is fixed between the inner wall of the platform base 34 and the extension rod 10. The diagonal reinforcing rod 14 enhances the connection strength between the extension rod 10 and the platform base 34.

[0038] Furthermore, tail wheel assemblies are installed on both sides of the bottom end of the platform base 34. The tail wheel assembly includes a universal wheel frame 3 installed at the bottom end of the platform base 34, and a tail wheel 1 is installed on the universal wheel frame 3 via a wheel axle bracket 2; a head wheel 11 is installed on the bottom end of the head of the extension rod 10 via a head wheel frame 12. The tail wheel 1 and the head wheel 11 mentioned above enable the entire working platform to be moved easily, thereby facilitating the subsequent movement of the platform to the required maintenance position and enhancing its flexibility of use.

[0039] Furthermore, an auxiliary handle 13 is fixed to the outer wall of the head of the extension rod 10. The auxiliary handle 13 facilitates subsequent assisted handling and steering of the entire platform.

[0040] Furthermore, telescopic support legs are fixed on both sides of the platform base 34. Each telescopic support leg includes a fixed support leg 5 that is fixed to the outer wall of the platform base 34 via a connecting plate 6 and bolts 7. An inner telescopic support leg 4 is installed inside the fixed support leg 5. These telescopic support legs facilitate stable and reliable support for the entire platform.

[0041] Furthermore, the ladder structure includes a central platform 27 fixed to the upper outer wall of the column 18. A first diagonal bar 8 and a second diagonal bar 9 are fixed parallel to each other between the bottom of the central platform 27 and the platform base 34. Multiple steps 33 are fixed between the first diagonal bar 8 and the second diagonal bar 9. A ladder railing 29 is fixed to the top of the second diagonal bar 9. A protective plate 28 is fixed between the first diagonal bar 8 and the second diagonal bar 9. This ladder structure facilitates subsequent workers to ascend the steps 33 to the central platform 27, thereby facilitating their final access to the top platform 24 for maintenance work.

[0042] Furthermore, a traction rod 31 is hinged to one side of the platform base 34 via a tie rod mounting seat 32, and a pull ring 30 is provided at the end of the traction rod 31. The aforementioned traction rod 31 facilitates subsequent traction and movement of the entire platform.

[0043] Furthermore, a telescopic platform 25 is slidably mounted on the bottom of the top platform 24 via a slide groove 38; the telescopic platform 25 facilitates the extension of the length of the top platform 24, thereby facilitating its connection with the aircraft air intake.

[0044] Furthermore, a climbing handle 26 is fixed to the upper outer wall of the lifting column 20. The climbing handle 26 facilitates climbing by subsequent workers.

[0045] Furthermore, the lifting and adjusting device includes a reinforcing base 15 fixed to the platform base 34. A hydraulic cylinder 17 is hinged to the top of the reinforcing base 15 via a hydraulic cylinder hinge seat 16. The top end of the piston rod 21 of the hydraulic cylinder 17 is connected to the bottom end of the top platform 24. This lifting and adjusting device enables the lifting and adjusting of the top platform 24. During operation, when the top platform 24 needs to be lifted and adjusted, the piston rod 21 is driven by the hydraulic cylinder 17, which in turn drives the top platform 24 to lift and adjust.

[0046] Furthermore, the lifting column 20 is made of channel steel, and the U-shaped groove of the channel steel forms a sliding fit with the guide wheel 19. This fit between the U-shaped groove and the guide wheel 19 ensures that the lifting column 20 can smoothly rise and fall.

[0047] Furthermore, a pin locking mechanism is provided between the lifting column 20 and the upright column 18. The pin locking mechanism includes a pin seat 35 fixed to the outer wall of the upright column 18, on which a pin 39 is fitted. The pin 39 engages with a pin hole 36 on a pin plate 37, which is fixed to the outer wall of the lifting column 20. This pin locking mechanism allows for height locking of the top platform 24 after height adjustment, ensuring the safety of subsequent operations. Once height adjustment is complete, the pin 39 locks the lifting column 20 and the upright column 18 together.

[0048] Furthermore, the pin holes 36 are machined at equal intervals on the pin plate 37. These pin holes 36 enable multi-level locking at different heights.

[0049] The working process and principle of this utility model:

[0050] When the aircraft's air intake needs to be inspected, firstly, the entire inspection platform is moved to the location of the air intake to be inspected. Then, the height of the top platform 24 is adjusted according to the height of the air intake. When the top platform 24 needs to be raised or lowered, the piston rod 21 is driven by the hydraulic cylinder 17, and the piston rod 21 drives the top platform 24 to be raised or lowered. The operators climb to the top platform 24 through the ladder structure and then carry out the corresponding inspection and maintenance work on the air intake.
