Description

Technical Field

[0001] This utility model relates to the field of aviation maintenance equipment technology, specifically to a mobile support for an aircraft maintenance platform. Background Technology

[0002] Existing aircraft maintenance platforms mostly use fixed foundations or simple mobile frames. Fixed platforms cannot be moved and have poor flexibility; while simple mobile frames generally have the following problems:

[0003] 1. Insufficient overall rigidity, making it prone to swaying during platform lifting or load-bearing;

[0004] 2. The lack of a stable support structure that integrates with the platform necessitates manual operation of the support legs, which is inefficient and carries the risk of being forgotten.

[0005] To address the aforementioned technical problems, this application proposes a mobile support for an aircraft maintenance platform. Utility Model Content

[0006] I. Technical problems to be solved

[0007] The technical problem this invention aims to solve is insufficient overall rigidity, which makes the platform prone to swaying during lifting or carrying loads. It also lacks a stable support structure that is linked to the platform, requiring manual operation of the outriggers.

[0009] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a mobile support for an aircraft maintenance platform, comprising a support base and a maintenance platform mounting frame. The support base is fixedly installed on the lower side of the maintenance platform mounting frame. The support base has a grid-shaped structure and is divided into a central closed area and four corner open areas. Mounting frames are rotatably installed inside the four corner open areas of the support base. Traveling wheels are installed on the lower side of the mounting frames. A drive shaft connects two adjacent sets of mounting frames. A drive assembly rotatably connected to the drive shaft is installed inside the central closed area of ​​the support base. The drive assembly drives the mounting frames to rotate, thereby adjusting the position of the traveling wheels.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] As attached Figure 1 Appendix Figure 3 and attached Figure 4 As shown, a mobile support frame for an aircraft maintenance platform includes a support base 1 and a maintenance platform mounting frame 2. The support base 1 is fixedly installed on the lower side of the maintenance platform mounting frame 2. The support base 1 has a grid-shaped structure, welded from high-strength steel. The double-layer frame structure design ensures the structural strength and stability of the support frame when bearing heavy platforms and personnel and tools. The support base 1 is divided into a central closed area and four corner open areas. Mounting frames 5 are rotatably installed on the inner side of the four corner open areas of the support base 1. Travel wheels 6 are installed on the lower side of the mounting frames 5. A drive shaft 7 connects two adjacent sets of mounting frames 5. A drive assembly rotatably connected to a drive shaft 7 is installed inside the central enclosed area of ​​the support base 1. The drive assembly includes a bidirectional threaded shaft 3 and multiple sets of push rods 11. The bidirectional threaded shaft 3 is rotatably installed between the two side walls of the central enclosed area of ​​the support base 1. A motor 4 connected to the end of the bidirectional threaded shaft 3 is installed on the support base 1. Movable frames 10 are installed on the outside of both sides of the bidirectional threaded shaft 3 and are connected by threads. Both sides of the movable frames 10 are rotatably connected to the push rods 11. The other end of the push rod 11 is rotatably sleeved on the outside of the drive shaft 7. The drive assembly drives the mounting frame 5 to rotate, thereby adjusting the position of the traveling wheels 6.

[0027] When moving the aircraft maintenance platform, start the motor 4, which drives the bidirectional threaded shaft 3 to rotate. The bidirectional threaded shaft 3 drives the two sets of moving frames 10 to move closer or further apart at the same time. The moving frames 10 drive the push rod 11 to move. The push rod 11 pulls the drive shaft 7 to rotate, thereby driving multiple sets of mounting frames 5 on the same side to rotate at the same time, supporting the traveling wheels 6 on the ground, and moving the aircraft maintenance platform.

[0028] When positioning the aircraft maintenance platform, the motor 4 rotates in one direction, which drives the bidirectional threaded shaft 3 to rotate in the opposite direction, which in turn drives the moving frame 10 to rotate in the opposite direction. The lower side of the support base frame 1 is provided with a U-shaped through groove 8 into which the mounting bracket 5 and the push rod 11 are embedded, so that the traveling wheels 6 are retracted into the four corner opening areas.

[0029] As attached Figure 1 and attached Figure 2 As shown, hydraulic telescopic rods 12 are installed on the lower side of the ends of multiple support rods of the support base 1. The extended ends of the hydraulic telescopic rods 12 face downwards and are equipped with foot pads 13. The foot pads 13 are made of solid polyurethane shock-absorbing pads. A central controller 9 connected to the multiple sets of hydraulic telescopic rods 12 is installed at the bottom of the maintenance platform mounting frame 2. The eight sets of hydraulic telescopic rods 12 are electrically linked through a central controller 9. The hydraulic telescopic rods 12 extend synchronously and automatically until they lift the entire support base 1 and platform, so that the traveling wheels 6 are off the ground. The weight is completely borne by the four hydraulic telescopic rods 12, forming a rigid support. The central controller 9 has a built-in pressure sensor and level, which can realize a one-button automatic leveling function. Even on uneven ground, it can ensure the absolute level of the support base 1 and the platform above, greatly improving the safety of operation.
