The folding type boarding ladder has enough strength and rigidity, is durable and easy to operate, can work reliably and can be stored, parked, carried and transferred conveniently; and the transferring occupied area is saved.
Description
Technical field:
The utility model is relevant with the airstair in the aircraft maintenance, and is special relevant with collapsible aircraft boarding ladder.
Background technology:
The aircraft boarding ladder is to be used for the equipment that the aviator goes on or off the plane and the aircraft line service must be used, and is one of visual plant in the aircraft floor maintenance work.At present, the type aircraft boarding ladder that use on the airport is fixed sturcture, has enough intensity, rigidity, and is durable in use, but still has following problem:
(1) integral structure: the bracing frame floor area is too big and be difficult for fractionation or folding and unfolding, and volume is big, heaviness, inconvenience carrying.
(2) loading and unloading are complicated: it is big that transition occupies the space, and the waste of loading transportation time space is bigger, and transportation is inconvenient.
The utility model content:
The purpose of the utility model is in order to overcome the deficiency of original aircraft boarding ladder; A kind of have enough intensity, rigidity, durable in use are provided, easy and simple to handle, reliable operation; Be convenient to store and park and carry transition, practice thrift the collapsible aircraft boarding ladder of transition floor area.
The purpose of the utility model realizes like this:
The collapsible aircraft boarding ladder of the utility model comprises the following ladder that movable wheel is arranged on first end, and first end is through ladder in turning joint and the following ladder second end bonded assembly; First end is equipped with the combined support frame through ladder on turning joint and the middle ladder second end bonded assembly between middle ladder and last ladder, three terraced body parts of airstair are under off working state; Since turning joint is installed, collapsible folding, satisfy aircraft and shift requirement fast; Meet miniaturization, portability principle; Middle ladder plays transition connection of ladder single-piece and supporting role, and the combined support frame plays the supporting & stablizing effect when work, guarantees that the ladder single-piece is stable.
The wheel fork of foot wheel is arranged in the above-mentioned activity wheel, with wheel fork bonded assembly transiting rod, be enclosed within on clamping bar one end on the transiting rod screw thread arranged; Jam nut is contained on the transiting rod and screw thread fit; The other end of clamping bar is connected with following ladder first end through attaching parts; Following ladder has been installed movable wheel, and movable wheel is Height Adjustable, can satisfy the transhipment demand under the different condition.
Upper hinge, following hinge are arranged in the above-mentioned turning joint; On the following hinge hinged draw-in groove, fixed card slot are arranged; The hinged card, the fixed card that stretch into respectively in hinged draw-in groove, the fixed card slot are arranged on the upper hinge, and first screw, one end passes fixed card slot, fixed card successively and cooperates with first nut upper and lower hinge is connected, and second screw, one end passes hinged draw-in groove, hinged card successively and cooperates with second nut upper and lower hinge is fixed; Centering part when wherein second screw is for rotation; Unclamp second nut during use, be withdrawn into outside the seam, can make upper and lower hinge upset.
On the second above-mentioned nut collar groove is arranged, in the collar groove collar is arranged, the effect of collar is that second screw, second nut are linked into an integrated entity with following hinge, prevents that part from coming off, and avoids occurring superfluity at the use scene.
Have an end to be hinged on the intermediate support beam on the middle ladder in the above-mentioned combined support frame, the two ends of many supports are hinged on intermediate support beam, middle ladder respectively or go up on the ladder.
On the above-mentioned last ladder handrail and hook are arranged, make things convenient for the maintenance of personnel during work, care work aircraft.
The collapsible aircraft boarding ladder of the utility model can launch rapidly through turning joint under contraction state, and the combined support frame can be guaranteed the reliability and stability of work.Easy and simple to handle, reliable operation are convenient to store and are parked and carry transition, practice thrift the transition floor area, can satisfy the war standard needs that army's fast reserve and multimachine kind ensure especially.
