AIRPLANE LOAD DEVICE

The invention concerns a mobile airplane load device with a framework, a relatively to the framework vertically displaceable main platform and a relative to the framework vertically displaceable front platform, as well as force means independent lifting and lowering of the platform, andockbaren to the airplane, whereby the upper surface serves the respective platform of the admission for load and/or unloading property.

A such displaceable airplane load device is for example well-known from the DE 37 30 415 C2. With this both the front platform and the main platform are carried by shears. Each platform is assigned a pair of shears. For the pair of shears of the Vorderplattform additionally an excavation cylinder is intended, which attacks at the yoke connecting the shears of the pair of shears. The main platform is raised by means of two chains, which are turned back within the range of roles, which are by means of vertically arranged hydraulic cylinder elevation and lowerable. During this airplane load device the shears for the respective platform have both basic function and guide function. The construction principle of the shears causes a maximum hoisting depth of the platforms, for particularly groß e of airplanes with according to high-lying load level is not sufficient. With such airplanes the load level of quite 8 meters or more is above the driving surface of the airplane.

Similar airplane load devices are well-known from the DE 21 30 968 A and US 399,320 77. With these a haulage system, which is formed from a multiplicity of transport rollers, is integrated into the main platform.

From practice it is well-known, größ to realise ere hoisting depths quite by means of shears, without the overall length of the vehicle vergröß to have ern. Here two or several shears systems arranged one above the other are used. Such an organization of an airplane load device is structurally very complex and expensively, on the other hand technically problematic, there groß e loads, with a very low overall height (520 mm) of the main platform, which is system-dependently prescribed, to be lifted and lowered must.

In the GB 2,311,506 A a mechanism is descriptive, which serves unloading an airplane, which landed at a place, which does not exhibit structure to the Beund unloading the airplane. Therefore the airplane takes up this structure, which must be installed after its landing on the ground. It exhibits a tower with four hitting a corner vines, which are embodied over roof and laterally props on the ground. In this tower a shears lifting table pushed from the vehicle trunk is installed above and lowered with fixed upper Ladeplattform its basic frames onto the ground, on which the tower rises. After the loosening of the upper platform this can be lowered and lifted, for the Ent and/or loading the airplane. The disassembly and admission of the mechanism into the airplane take place in reverse. With such a mechanism leave themselves, under which tower, in ranges without infrastructure for the loading and unloading the airplane, no airplanes load which shears construction and the employment of the airplane with very high-lying load level. A load device, which concerns a similar problem, is well-known from the DE-OS 25 40 395.

In the DE 43 31 605 C2 a transport vehicle with portalförmigem chassis is descriptive, that transporting quaderförmigen things, as paper or sticking sheet serves. The chassis takes up vertically elevated and lowerable carrying organs, which serve seizing and raising of the sheet pile by means of a transportation palet. Furthermore in the chassis clamping organs are held, which are designed as two plates each, those opposite Auß enseiten the ground pile influence. Thereby it is guaranteed that the sheet pile is not shifted with proceeding in itself.

Furthermore it is well-known to ship containers by means of a gantry crane. The bar-like handling cradle for the hanging admission of a container is in vertically oriented props of the portal frame elevation and lowerable, so that, due to that displaceableness of the portal frame on the driving surface of a container terminal container proceed at will, to be stacked and unpacked can. With a such displaceable gantry crane Stapelhöhen up to four containers can be achieved. With such a stacker crane the operator's cab is in the upper range of the portal in all rule. Such constructions do not have a platform with conveyer system.

Task of the invention is to be trained further it a mobile airplane load device the entrance kind mentioned in such a way that with these airplanes with particularly groß EN load heights to be loaded and unloaded can.

The task is solved during a mobile airplane load device the entrance kind mentioned by the fact that the framework is designed as portal frames, and the main platform as well as the Fronplattform in vertical props of the portal frame are stored.

The invention separates from the operational principle the use of shears constructions with mobile airplane load devices. Instead the main platform and the front platform are stored in the vertical props of the portal frame of the airplane load device. According to the load and/or unloading level of the airplane given by the type of aircraft the portal frame in its height is to be dimensioned. The portal frame represents the rigid element, in which the platforms can be led defined. Furthermore it serves the admission of the chassis and the aggregates of the airplane load mechanism, in particular that to lifting and lowering the platforms, the aggregates to operation of a haulage system at least integrated into the main platform, the chassis, possible strut cylinder to supporting the portal frame opposite the ground when the loading and unloading etc.

In addition, the airplane load device is in particular self-propelled, can quite be equipped without drive for driving, so that it is dragged. The procedure of the load device can take place with or without load, whereby here the main platform is preferentially in a relatively lower position. In all rule in the corners of the portal frame wheels will be intended, thus at least four wheels and/or four pairs of wheels. Should be propelable two or several wheels and/or pairs of wheels. Preferably it concerns an all-wheel drive. If all wheels and/or pairs of wheels are guidable, can be proceeded the airplane load device arbitrarily, in particular lengthwise, crosswise, in the circle or diagonally.

So that and/or the discharge process can go optimally, the main platform and the front platform should be separately elevation and lowerable. Preferably additional means are intended for producing a bank of the front platform. Thereby this can optimally concerning the Auß enhaut the airplane to be aligned. As stroke drive for the platforms is applicable in particular an electric drive or the combination of an electrohydraulical drive. It is also conceivably as stroke elements be-blazes chain courses to use.

In order to be able to andocken the front platform particularly simply to the airplane, preferably provide is it with a telescopic Ausschub. The front platform, in particular the Ausschub consists of individual segments, so that with in Auß obtaining position present äuß eren segments also airplanes to be loaded and/or unloaded can, their door and/or loading hatch width are smaller.

The controlling and operation of the airplane load device preferably take place from above. It is in particular ascent leaders for the driver in the range of a prop of the portal frame intended. The operator's cab moves zweckmäß industrial union with the Vorderplattform and is for example installed beside this. Gemäß a special execution form of the invention it is intended that the upper range of the portal frame serves, in particular its upper frame profile of the admission of the drive for the aggregates of the airplane load mechanism. The range of the portal frame present under it makes thereby the unhindered displaceableness of the platforms, in particular for the main platform possible. In this connection it is regarded as favourable, if the front platform auß erhalb the vertical projection of the portal frame is arranged.

In order to be able to promote the property simply and fast in the range of the platforms, the platforms should be provided with conveyer systems. Further means should be intended for simplified lateral shipping. Thus the main platform points a side load role for example in its rear range up and/or the portal frames laterally one very deeply, thus slightly over the travelled surface lying side load role. With lowered main platform the loading of the main platform can take place uncomplicatedly by means of this side load role in the center of the airplane load device. Additionally, in particular during a truck loading, a tail loading should be possible, thus a loading of the main platform over their rear end.

So that the airplane load device does not swing with unloading or takes an inclined position, extendable stabilizing columns should be intended in the range of the wheels on the ground. In order to be able to drive on if necessary, the minimum upward gradients with horizontal oriented platforms, existing on the airport apron, the individual wheels should be slightly liftable and/or lowerable.

Zweckmäß industrial union can be lifted and/or lowered during the airplane load device during driving the load.

In particular with very groß EN airplanes can be additionally provided with a passenger hoist the airplane load device.

Further characteristics of the invention are represented in the Unteransprüchen, to the description of the only figure and figure, whereby it is noticed that all single characteristics and all combination of single characteristics represent further inventive arrangements.

In the figure the invention is described on the basis a remark example, without being on that limited. This figure shows the displaceable airplane load device in a spatial opinion.

The displaceable airplane load device 1 possesses a portal frame 2. these exhibits within its upper range a rectangular frame profile 3. The corner areas of the frame profile 3 four vertical props 4 and/or guidance masts of the portal frame 2 go off. The respective lateral pair of props is connected by means of a horizontal prop 5 running on middle level. Down the respective lateral pair of vertical props 4 is braced, by two L-shaped ones, in kind of a wheel housing trained frame parts 6, which an axially swivelling side load role of 7 connects. In each corner of the portal frame 2 a chassis 8 is arranged in the extension underneath the respective vertical prop 4, in the remark example a wheel 9 is assigned to which. Each wheel 9 is guidably, propelable and in break legs stored, so that the possibility exists to raise or lower the respective wheel. Neighbouring the respective Rades 9 a stabilizing column 10 is stored in the assigned frame part 6, which is raisable by this on the travelled surface lowerable and. In the framework one of the two front vertical props 4 is intended ascent leaders a 11.

A main platform 12, which is rectangular trained in their vertical projection, exhibits a width, which is slightly smaller, as the width distance of the vertical props 4. the length of the main platform 12 is clearly größ it as the horizontal longitudinal dimension of the portal frame 2, so that the main platform stands out 12 in the back from the portal frame 2, for example over about 1/3 of their overall length. The main platform 12 is stored in guidance 13 of the vertical props 4. The storage is made not directly in the guidance 13, but by carriages, so that the main platform 12 with their upper surface can be lowered under the level of the vertical props 4 up to the level of the side load role of 7 of the portal frame 2. Also in the back the range of the main platform 12 outstanding from the portal frame 2 is at least provided on a side with a side load role of 14. The admission of the property serving upper surface 23 of the main platform 12 is provided with a haulage system 15, which exhibits for example a multiplicity of propelable roll-like promotion elements. In front, directly to the main platform 12 anschließ end, is vertically displaceable stored a front platform 16 in the portal frame 2. Their width is größ it as those the main platform, there it auß erhalb the portal frame 2 arranged and in the front sides of the front vertical props 4 is stored. The front platform 16 takes up an operator's cab 17. By means of single adjustment cylinders 18 the front platform 16 can be lifted, lowered and be slightly crosswise bent from the horizontals. In the front range the front platform 16 points laterally äuß ere folding segments 19 and a telescopic present between them, horizontal in and extendable platform section 20 up.

Not shown the drive for the various aggregates of the airplane load device is 1, in particular for lifting and lowering the two platforms 12 and 16, driving the telescopic section 20 out of the front platform 16, operation of the haulage system 15 and the side load roles of 7 and 14, propelling the wheels 9 and the pertinent brakes as well as a remote cylinder 21 for the respective wheel set. The drive for these aggregates and/or the control is in the upper range 22 of the portal frame 2 is preferably arranged, that by the upper, box-like frame profile 3 enclosed.

Shown the airplane load device is 1 with essentially completely raised front platform 16 and partly raised main platform 12, in each case without load present at the platforms illustrated in the figure.

With strichlierten lines their lowered position is illustrated for the rear range of the main platform 12. And/or unloading within the central range of the main platform 12 is made by the side load role 7. arranged within the range of the break-through 24.

The figure illustrates that due to the selected portal frame construction on the one hand one quite groß e vertical lift of the platforms by appropriate long training of the vertical props 4 to be realised knows, is on the other hand a sufficient rigidity of the system by the upper box-like frame profile 3 and the storage of the main platform 12 and the front platform 16 in the vertical props 4 ensured.
