Description

An auxiliary vehicle for aviation maintenance

technical field

The utility model relates to aircraft maintenance equipment, in particular to an auxiliary vehicle for aviation maintenance.

Background technique

At present, in the field of aviation, the MRO (maintenance, repair, operation) industry plays an irreplaceable role. Whether it is a transport aircraft or a general-purpose aircraft, it is required for safe operation and pre-flight and post-flight inspections and shutdown line maintenance. Inspection, overhaul, and repair of system accessories are important guarantees for safe flight of the aircraft. Three factors have the largest impact on the long-term growth of the aviation maintenance market: the expansion of fleet size, the improvement of aircraft utilization rate and the slight increase of labor cost. From the current point of view, the air transport industry is still a low-yield industry, and the increase in income is proportional to the cost. Therefore, cost reduction is particularly important in the aviation maintenance business. According to the law of the development of the aviation industry in developed countries, airlines will greatly reduce or divest non-core assets such as MRO and simulator training in the future, and replace them with lower-cost outsourcing services; therefore, the outsourcing of aviation maintenance and training will It is the general trend. Because of the large volume of aviation equipment, it often needs other auxiliary equipment to complete its maintenance, and the auxiliary vehicle for aviation maintenance is one of the more important auxiliary equipment.

Contents of the invention

The technical problem to be solved by the utility model is that the existing auxiliary vehicles for aviation maintenance have simple functions and are difficult to meet maintenance requirements, resulting in slow aircraft maintenance.

In order to solve the above technical problems, the utility model provides an auxiliary vehicle for aviation maintenance, which includes a head, a body, a working lifting platform, a hydraulic cylinder, an escalator, and a tool placement table; There are wheels under the bottom of the car body; the hydraulic cylinders are arranged side by side on the car body; the working lifting platform is installed horizontally on the top of the piston rod of each hydraulic cylinder; guardrails are provided on the surrounding edges of the working lifting platform through the supporting columns; the escalator is installed on the car body. On the rear side, handrails are fixedly installed on both sides of the escalator; a chute is provided at the bottom of the tool placement platform; the chute is buckled on the slideway on the working lifting platform; a guard plate is provided on the top of the tool placement platform; A drawer and a tool cabinet are respectively arranged on the front side of the tool placing table, and the drawer is located above the tool cabinet.

The hydraulic cylinder can be used to adjust the height of the working lifting platform according to the needs to achieve maintenance support at different heights; the combination of the chute and the slideway can facilitate the movement of the tool placement table without random shaking; the design of the escalator is more convenient for maintenance Personnel board the working lifting platform.

As a further limiting solution of the present invention, a handle is provided on the rear side edge of the guardrail; the handle is located above the escalator. The pull handle can be used to hold when climbing from the escalator to the working lifting platform, which enhances the safety and convenience of use.

As a further limiting solution of the present invention, non-slip rubber is provided on the upper surface of the step bar of the escalator. The use of anti-slip rubber can enhance the anti-slip performance and enhance the safety during use.

As a further limiting solution of the present invention, the handrail is mounted on the escalator through a hinge and can be folded towards the middle of the escalator. Foldable installation, easy to carry and use.

The beneficial effect of the utility model is that: the height of the working lifting platform can be adjusted according to the needs by adopting the hydraulic cylinder, so as to realize the maintenance support of different heights; the cooperation of the chute and the slideway can facilitate the movement of the tool placement platform without random shaking; The design of the escalator is more convenient for maintenance personnel to board the working lifting platform.

detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

As shown in Figures 1-3, the auxiliary vehicle for aviation maintenance disclosed by the utility model includes: a locomotive 1, a car body 12, a working lifting platform 5, a hydraulic cylinder 6, an escalator 9 and a tool placement platform 2.

Wherein, headstock 1 is installed on the front end of car body 12, and is provided with wheel 13 below car body 12; Hydraulic cylinder 6 is arranged side by side on car body 12; The top of the working lift platform 5 is provided with a guardrail 3 through the support column 4 on the periphery of the working lifting platform 5; The bottom of the bottom is provided with a chute 17; the chute 17 is fastened on the slideway on the working lifting platform 5; a guard plate 14 is provided on the top of the tool placement platform 2; drawers 15 and A tool cabinet 16, and the drawer 15 is located above the tool cabinet 16; a handle 8 is provided on the rear side edge of the guardrail 3; the handle 8 is located above the escalator 9; an anti-slip rubber 18 is provided on the upper surface of the step bar 11 of the escalator 9; Handrail 10 is installed on the escalator 9 by a hinge, and can be folded toward the middle of escalator 9 .
