Supporting device for civil aviation maintenance

Abstract

The invention discloses a supporting device for civil aviation maintenance. The supporting device comprises a base, a hydraulic elevator, a supporting mechanism, a dust removal mechanism and a hoisting mechanism. Three hydraulic buffers are installed on the hydraulic elevator, the supporting range is large, the overall structure is stable, time and labor are saved, a protective guard and an iron gauze are further arranged, the whole device has enough use space and is more convenient to maintain, a non-slip mat is installed on the surface of a lifting table, maintenance personnel can feel more relieved during maintenance, maintaining of aircraft components is facilitated, through the arrangement of the hoisting mechanism, contact with bottom surface maintenance personnel is facilitated, part of maintenance components on the aircraft are replaced in time, enough space is also formed in the lifting table to store the components needing to be maintained, and through the arrangement of the dust removal mechanism and air injection dust removal of an air pump, accumulated dust on the surface and the interior of the aircraft can be effectively removed; and through an arranged illuminating lamp, all parts on the aircraft can be seen more clearly, and maintenance is more facilitated.

Description

technical field [0001] The invention relates to the technical field of civil aviation maintenance, in particular to a supporting device for civil aviation maintenance. Background technique [0002] Aircraft maintenance includes aircraft body structure and accessories repair, assembly and commissioning, aircraft test flight and its fault diagnosis and troubleshooting, aircraft repair technology management, aircraft outfield maintenance, etc. The aircraft is large in size and high in the aircraft body, requiring support devices Access to the bottom of the repaired part requires a support device: [0003] The comparative document CN206108800U discloses a special automatic elevator for aircraft maintenance personnel, including a working platform, a hydraulic cylinder, a hydraulic pump, a lifting mechanism, a guardrail, etc. During work, the hydraulic cylinder is opened by the power provided by the hydraulic pump, and the hydraulic cylinder drives the lifting mechanism to open th...

Problems solved by technology

[0003] The comparative document CN206108800U discloses a special automatic elevator for aircraft maintenance personnel, including a working platform, a hydraulic cylinder, a hydraulic pump, a lifting mechanism, a guardrail, etc. During work, the hydraulic cylinder is opened by the power provided by the hydraulic pump, and the hydraulic cylinder drives the lifting mechanism to open the elevator. The working platform is raised to a suitable height; however, when the device is in use, the space for the upper fixing plate is too narrow, and maintenance personnel usually carry a lot of maintenance tools, which is not convenient for maintenance on the device. When encountering maintenance parts that need to be replaced, It is difficult to communicate with the ground, and there is no space to store the slightly larger maintenance parts; the device does not have the function of dust removal, and the surface and interior of the aircraft will inevitably accumulate dust after use. Due to the precise internal structure of the aircraft, a large amount of dust accumulation is not easy for the aircraft Maintenance of components; the device is not equipped with a support mechanism, and when the repair personnel are working, the working platform and the outside of the aircraft are not fixed, and the repair platform may shift or shake, which brings inconvenience to the repair; the reference document CN207953837U discloses a civil aviation maintenance Supporting device, the top of the device is provided with a retaining ring, an elastic column, and an elastic cylinder. When working, as the lifting platform rises, the retaining ring fits with the lower surface of the aircraft, which plays a certain role in protecting the user; but the The device cannot judge the height between the maintenance platform and the aircraft by itself, and there is a risk of the maintenance platform rising too high and colliding with the aircraft
