Description

Technical Field

[0001] This utility model relates to the field of aircraft wing maintenance technology, specifically to a telescopic wing inner repair platform. Background Technology

[0002] The wing is one of the most important components of an aircraft. It is mounted on the fuselage and its primary function is to generate lift, working in conjunction with the tail. Maintenance work on an aircraft often involves repairs to the inner side of the wing, which is a notoriously difficult area to access and requires a specialized platform.

[0003] Currently, both domestically and internationally, the maintenance process for the inner side of aircraft wings mostly utilizes scaffolding or aerial work platforms for access. However, both methods have drawbacks: 1. Scaffolding is relatively cumbersome to erect, and adjusting its position requires a significant amount of time, resulting in poor flexibility; 2. Aerial work platforms have a small working area, and each adjustment can only cover a small portion of the inner side of the wing, which is not conducive to the commencement of maintenance work and leads to low efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a telescopic wing inward repair platform, which is more flexible in use and can improve the efficiency of aircraft wing inward maintenance.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A retractable wing inward repair platform, characterized in that it includes a main platform, a retractable platform, a manned lifting platform, a first rigid chain drive mechanism, and a second rigid chain drive mechanism. The main platform has a main support column assembly underneath for ground support. The retractable platform and the first rigid chain drive mechanism are both located below the main platform. The retractable platform is slidably connected to the main platform and can extend from one end of the main platform. The outer end of the rigid chain of the first rigid chain drive mechanism is connected to the retractable platform, and the first rigid chain drive mechanism drives the retractable platform to slide horizontally. The manned lifting platform and the second rigid chain drive mechanism are both located at the other end of the main platform. The manned lifting platform can slide up and down. The upper end of the rigid chain of the second rigid chain drive mechanism is connected to the manned lifting platform, and the second rigid chain drive mechanism drives the manned lifting platform to rise and fall.

[0007] A further technical solution of this utility model is as follows: guide rails are provided on both sides of the bottom of the main platform, guide grooves are provided on the inner side of the guide rails, and sliding connecting strips are provided on both sides of the telescopic platform. The sliding connecting strips are slid into the guide grooves and can slide within the guide grooves.

[0008] A further technical solution of this utility model is as follows: guide wheels are provided at intervals in the guide groove, and a limiting groove is provided on the outer side of the sliding connecting strip, with the guide wheels located in the limiting groove.

[0009] A further technical solution of this utility model is as follows: a vertical guide column is provided at one end of the main platform for installing the manned lifting platform, and a sliding sleeve is provided on one side of the manned lifting platform, the sliding sleeve being fitted onto the guide column.

[0010] A further technical solution of this utility model is as follows: the main support assembly includes four main supports located at the four corners of the main platform, each main support is provided with a reinforcing diagonal brace between it and the bottom of the main platform, and casters are provided under the main supports.

[0011] A further technical solution of this utility model is: the end of the telescopic platform away from the main platform is provided with an auxiliary support column assembly for supporting it on the ground.

[0012] A further technical solution of this utility model is: the auxiliary support assembly includes two auxiliary supports located at two corners of the telescopic platform.

[0013] A further technical solution of this utility model is that guardrails are provided on both sides of the main platform and at the edge away from the telescopic platform.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention can be directly pushed and used under the inner side of an aircraft wing, eliminating the need for cumbersome scaffolding construction. Furthermore, the coverage area of ​​the repair platform can be adjusted by sliding the telescopic platform via a first rigid chain drive mechanism, making it more flexible and improving its applicability. Compared to aerial work platforms, it provides a larger working surface. Additionally, given the limited space inside the aircraft wing, this invention features a personnel lifting platform driven by a rigid chain mechanism for easy access. This invention improves the safety and efficiency of maintenance work inside the aircraft wing.

[0016] This invention uses a rigid chain drive mechanism as the power source, which has a compact structure, smooth transmission, and can improve space utilization.

[0017] This invention can be applied to the inspection of the inner underside of the wings of wide-body aircraft, meeting the access needs of workers for wing maintenance, including engine maintenance. Furthermore, it can be widely used on different aircraft models, demonstrating good applicability. Attached Figure Description

[0037] When it is necessary to repair the inner side of the aircraft wing, the repair platform is pushed directly to the underside of the inner side of the aircraft wing. According to the repair range, the extension length of the telescopic platform 2 is adjusted by the first rigid chain drive mechanism 3. After adjustment, the auxiliary support 9 is lowered and placed on the ground. Then, personnel can rise to the top of the repair platform through the personnel lifting platform 5 to carry out repair work.
