A rotating mechanism for aero-engine installation and maintenance

Abstract

The invention discloses a rotating mechanism for mounting and maintaining an aero-engine, which comprises a hydraulic actuator cylinder, a front main bearing beam of an aircraft engine compartment, a front framework, an engine, cross beams, a rear bearing beam of the aircraft engine compartment, a rear framework, pins, an auxiliary mount, an accessory casing and a main mount, wherein the front framework, the rear framework and one cross beam form a fixed framework mechanism, the engine is fixedly arranged in the framework mechanism through the main mount and the auxiliary mount, the engine can be mounted on an aircraft through fixing the framework mechanism on the aircraft engine compartment, and the framework mechanism of the engine rotates by taking the pins as the axis and is used for controlling the rotating angle and height of the engine through the stretching length of the hydraulic actuator cylinder. The rotating mechanism for mounting and maintaining the aero-engine has the advantages that the stability is good, the weight of the engine is favorably lightened, the design difficulty of the engine is reduced, the occupied space is small, the maintaining efficiency is improved, the working reliability of the main mount and the auxiliary mount of the engine is ensured, and the rotating mechanism is suitable for equipment needing repeated hoisting maintenance in other industries.

Description

technical field [0001] The invention relates to a mechanism for installation and maintenance of aviation products, in particular to a rotating mechanism for installation and maintenance of aero-engines. Background technique [0002] The aero engine is the core component of the aircraft, and it requires regular maintenance work to ensure that the aircraft's attendance, safety and maintenance costs are not affected. In engine maintenance, the maintenance of engine accessories occupies most of the maintenance workload. Therefore, the convenience of engine accessories maintenance is of great significance to improve the maintainability of engines and aircraft. [0003] For aircraft installed with embedded engines, in order to ensure that the aircraft has a small windward area, the accessories of the engine often need to be arranged on the side or under the side, so that the distance between the engine accessories and the aircraft bulkhead is small, and the distance between the en...

Problems solved by technology

Adding maintenance windows destroys the structural integrity of the aircraft and for some specific aircraft configurations the maintenance window may be limited by other structures making it infeasible; existing hair loss maintenance efforts require external large equipment or tools , bases or maintenance plants with complete hardware facilities can provide these equipments, but it is difficult for many other airports to meet these conditions, and because these equipments are large in size, they are not easy to transport and deploy, thus limiting the flexibility of large and medium-sized aircraft maintenance sex
