Problems solved by technology

[0003] Due to the differences in the heights of aircraft engines and propeller systems, as well as the different maintenance positions, the traditional fixed-height maintenance platform cannot well adapt to the maintenance requirements of height and width changes. It is necessary to adjust the height and position of the maintenance platform at any time to achieve the above. In the maintenance operation process, and the above-mentioned fixed platform structure maintenance operation is adopted, the labor intensity is high, the workload is large, and the use is ineffective and

Embodiment 1

[0039] see Figure 1-6 , engine and propeller system working platform, it comprises bottom support platform 25, and the top of described bottom support platform 25 is fixed with first inner support frame 9 and second inner support frame 18, and the outside of described first inner support frame 9 passes through The first outer lifting frame 8 is slidably sleeved on the first guide wheel structure, and the second outer lifting frame 19 is slidably sleeved on the outside of the second inner support frame 18 through the second guide wheel structure. The top is fixed with a first top platform 13, and the top of the second outer lifting frame 19 is fixed with a second top platform 17, and is fixedly connected between the first top platform 13 and the second top platform 17; The side of the platform 13 is fixed with an upper ladder 5, and a follow-up ladder 4 is installed between the upper ladder 5 and the bottom support platform 25 through a sliding structure; A lifting mechanism ...

Embodiment 2

[0051] The using method of engine and propeller system working platform, it comprises the following steps:

[0052] Step 1: With the support of the supporting casters 1, push the entire working platform to move to the location of the aircraft engine and propeller that need to be overhauled;

[0053] Step 2: After initially adjusting the position of the working platform, stretch out the lifting support rod 2, and then fix and support the entire working platform to ensure its stability;

[0054] Step 3: According to the height of the engine, when the height of the platform needs to be adjusted, control the motor 27 of the lifting mechanism, drive the screw lifter 30 through the motor 27, and then drive the second outer lift frame 19 and the first outer lift frame through the screw lifter 30 8. Rise along the corresponding guide wheel structure along the second inner support frame 18 and the first inner support frame 9, and then realize the raising of the first top platform 13 an...

Abstract

The invention provides an engine and propeller system working platform and a using method. A first inner supporting frame and a second inner supporting frame are fixed to the top of a bottom supporting platform. The first inner supporting frame is slidably sleeved with a first outer lifting frame through a first guide wheel structure. The second inner supporting frame is slidably sleeved with a second outer lifting frame through a second guide wheel structure, a first top platform is fixed to the top of the first outer lifting frame, a second top platform is fixed to the top of the second outer lifting frame, and the first top platform and the second top platform are fixedly connected; an upper crawling ladder is fixed to the side face of the first top platform, and a follow-up crawling ladder is installed between the upper crawling ladder and the bottom supporting platform in a matched mode through a sliding structure. A lifting mechanism is arranged between the second inner supporting frame and the second outer lifting frame, and an outwards-extending workbench is installed at the top of the second top platform in a sliding fit mode.

Description

technical field [0001] The invention relates to the field of aircraft maintenance ladders, in particular to a working platform for engines and propeller systems. Background technique [0002] In the process of aircraft maintenance and repair, it is necessary to use a working platform to maintain and use the aircraft engine and propeller system at a higher position. The existing common way is to set up scaffolding or a commonly used mobile maintenance platform to realize the maintenance of the above parts . [0003] Due to the differences in the heights of aircraft engines and propeller systems, as well as the different maintenance positions, the traditional fixed-height maintenance platform cannot well adapt to the maintenance requirements of height and width changes. It is necessary to adjust the height and position of the maintenance platform at any time to achieve the above. Overhaul operation process, and adopt above-mentioned fixed platform type structure overhaul oper...
