Abstract
Disclosed is combined sliding stair-type passenger boarding stairs, which relates to aviation ground facilities. The passenger boarding stairs are equipped with fixed stairs and sliding stairs, wherein the sliding stairs comprise lower sliding stairs and lengthened stairs. Besides, the top portion of the lower sliding stairs and the bottom portion of lengthened stairs are respectively equipped with flanges, screw bolts are used to connect and fix the flanges, and terrace guard bars are mounted at the top of the lengthened stairs. The sliding stairs and the lengthened stairs of the combined sliding stair-type passenger boarding stairs are simple and convenient to be assembled and disassembled and capable of realizing road transport of super-high passenger boarding stairs, thereby being adaptable to aircraft super-high passenger boarding stairs.
Description
Technical field
The utility model relates to aviation surface facility field, says it is a kind of assembling slip ladder type ladder vehicle that satisfies superelevation ladder vehicle road driving in detail.
Background technology
As everyone knows, the aircraft ladder vehicle is according to the difference of type height, and the maximum height of lift of ladder vehicle mainly contains 4.4m, 5.4m, several specifications of 5.8m.For the operating altitude and the requirement of transition shipping height that guarantee the aircraft ladder vehicle, the aircraft ladder vehicle is typically provided with fixed ladder and side-rolling ladder, and side-rolling ladder stretches out and satisfies the cabin altitude requirement during work, and side-rolling ladder is regained and satisfied the requirement of 4.5m limit for height when travelling.Reach the ladder vehicle of 8m for operating altitude, the ladder vehicle ride-height of existing structure will can't be carried out road driving above 6m.
Because ride-height will can't be carried out the deficiency of road driving above 6m after there is the lengthening side-rolling ladder in existing aircraft ladder vehicle, have significant limitation during use, can not satisfy the requirement that the aircraft ladder vehicle carries out road driving.
Summary of the invention
To can't carry out the deficiency of road driving above 6m for ride-height after overcoming existing aircraft ladder vehicle existence lengthening side-rolling ladder, the utility model assembling slip ladder type ladder vehicle adopts detachable lengthened ladder, unloads lengthened ladder and can effectively reduce ride-height.
The technical scheme that the utility model technical solution problem is adopted is: assembling slip ladder type ladder vehicle, be provided with fixed ladder and side-rolling ladder, it is characterized in that: side-rolling ladder is combined with lengthened ladder by the lower slider ladder, the top of lower slider ladder and the bottom of lengthened ladder are respectively equipped with flange, by bolted connection, the platform guardrail is located at the lengthened ladder top between the flange.
The beneficial effects of the utility model are: owing to adopt the compound type side-rolling ladder, lengthened ladder is detachable, can effectively reduce the ladder vehicle height behind the dismounting lengthened ladder, satisfies the requirement of travelling.The utility model is applicable to aircraft superelevation ladder vehicle.
Description of drawings
Fig. 1 is the utility model assembling slip ladder type ladder vehicle motoring condition structural representation;
Fig. 2 is the utility model working state structure scheme drawing.
Fig. 3 is the structural representation behind the utility model dismounting lengthened ladder.
Fig. 4 is the utility model lengthened ladder structural representation.
Mark is among the figure: car chassis 1, fixed ladder 2, side-rolling ladder 3, lengthened ladder 4, flange 5, platform guardrail 6.
The specific embodiment
Below in conjunction with accompanying drawing, assembly type passenger conveyor installations of the present utility model is described further.
In Fig. 1, car chassis 1 is the means of delivery of assembling slip ladder type ladder vehicle, and fixed ladder 2 bottoms and car chassis rear portion are hinged, side-rolling ladder 3 and fixed ladder 2 sliding block joints, lengthened ladder 4 is connected through flange 5 with side-rolling ladder 3, and can dismantle easily, and platform guardrail 6 is vertexs of car load.
When side-rolling ladder 3 was in retracted state, the minimum altitude of platform guardrail 6 still surpassed 5 meters, and this moves highly in the venue, but can't be by highway transition or transportation.
In Fig. 2, when side-rolling ladder 3 all stretched out fixed ladder 2, the maximum height of the platform guardrail 6 at lengthened ladder 4 tops can reach more than 8 meters.
In Fig. 3, after the dismounting of flange 5 places, the maximum height of side-rolling ladder 3 can carry out over-the-road transportation easily less than 4 meters with lengthened ladder 4.
In Fig. 4, the lengthened ladder 4 after the dismounting can transport separately, and the set flange 5 in its underpart can be integral with flange 5 bolt togethers of side-rolling ladder 3.
