Description
Technical field
The utility model relates to a kind of aircraft washing plant, especially relates to cleaning with the structure of cranking arm.
Background technology
Airplane skin is take aluminum alloy as main material, cooperates the macromolecule resin material of a part of high tensile force resistance and steel to make.In when flight, be subjected to being infected with of pollutants in fuel exhaust gas, air suspension particle and the cloud and mist, can gather the filth of constant weight on its shell, these filths can increase the weight of aircraft, cause consumption of fuel to rise, pollutants also can corrode surface of shell in addition, affects aircraft safety and controls.
In order to guarantee safety, the method for cleaning that usually adopts is to use manual type, at casing surface spraying purging medium, and scrubs with cleaning brush.Because the aspect ratio of modern civil aircraft is higher, when cleaning upper housing, particularly when cleaning vertical fin, need to personnel be lifted on the higher position with carrier, higher to security requirement, manually-operated cleaning efficiency is lower in addition.Occurred some for this reason and had the cleaning Vehicle that lifting is cranked arm, the top of cranking arm is provided with cleaning brush, cranks arm by hydraulic pressure or electronic mode lifting, realizes the casing of high position is cleaned.But how cranking arm of commonly using at present is comprised of upper arm and underarm, and lift height and lifting are limited in scope, and can not adapt to the requirement of comprehensive cleaning airplane skin.
Summary of the invention
The purpose of this utility model provides a kind of aircraft and cleans with cranking arm, and uses this to crank arm, and more lift heights and lifting scope can be provided, the Fit Models variation.
Technical solution of the present utility model is: a kind of aircraft cleans with cranking arm, it comprises the upper arm that is articulated and connected in turn, middle arm and underarm, and first hydraulic actuating cylinder, the second hydraulic actuating cylinder and the 3rd hydraulic actuating cylinder, wherein the two ends of the first hydraulic actuating cylinder are hinged on respectively on upper arm and the middle arm, the two ends of the second hydraulic actuating cylinder are hinged on respectively on middle arm and the underarm, and an end of the 3rd hydraulic actuating cylinder is hinged on the underarm.
Crank arm and comprise the upper, middle and lower arm that is articulated and connected in turn, each arm all can be under the drive of hydraulic actuating cylinder, relatively rotate take the hinged place as axle, therefore can adapt to different requirement for height, the height after all launching is higher, can adapt to the requirement that present generation aircraft top or vertical fin clean fully, each arm all can launch and fold in addition, operating mode is various, and its lifting scope and mode be variation also, can be suitable for dissimilar aircraft and the cleaning at position.
Described middle arm and underarm are class V-arrangement hollow square tube, and described upper arm is the yi word pattern hollow square tube.Provide enough intensity on the basis of saving material, and the height that middle arm and underarm take after folding is lower, also makes things convenient for the setting of hydraulic actuating cylinder.
Along being respectively equipped with brace panel on the two side of the V-arrangement of described middle arm and underarm bottom, play the effect of strengthening local structure intensity.
Be provided with L shaped articulated section at described upper arm, an end of described the first hydraulic actuating cylinder is hinged on this L shaped articulated section.The position that can make upper arm keep relative level is used for the cleaning to the fuselage side.
Be respectively equipped with the first articulated section and the second articulated section at the two ends of described middle arm, be respectively equipped with the 3rd articulated section and the 4th articulated section at the two ends of described underarm, the other end of described the first hydraulic actuating cylinder is hinged on the first articulated section, one end of described the second hydraulic actuating cylinder is hinged on the second articulated section, the other end is hinged on the 3rd articulated section, and an end of described the 3rd hydraulic actuating cylinder is hinged on the 4th articulated section.Special articulated section is set, is used for the connecting fluid cylinder pressure, the convenient connection, be convenient to maintenance.
The utility model has the advantages that: fold and launch conveniently, exercisable height is high, and Applicable scope is extensive, and accessibility cleaning position is many, strong adaptability.
