Nersorgungsanordnung

The invention relates to a supply arrangement in the form of a vertically or essentially vertically displaceable column element which can be lowered in a receptacle set in a floor area such as an airport runway, such as a shaft, or can be raised through an opening therefrom and at least one of which, for example, can be used for electricity. Water, oil and / or air leading supply line comes out, which can be pulled out of the receptacle along the column element to the desired extent.

A corresponding supply arrangement can be found in DE 37 43 393 C2, in which, when the column element is in the extended position, it closes or largely closes the opening. The pillar element has a cuboid shape with closed side walls, into which connector receptacles or connections for air are embedded. The column element itself is connected to counterweights in order to pull the column element out of a shaft or to push it into it without great effort.

The closed walls serve to ensure that liquid cannot penetrate the shaft. Due to the geometry of the column element, it is not possible to connect it to a large-sized hose, via which an aircraft is supplied with conditioned air. From DE 296 00 430 U1 a pull-out media connection is known which comprises a connection unit which can be raised from a shaft pipe or lowered into it in the form of a cylindrical receiving pipe. This has an intermediate floor which, when the connection unit is moved out, closes a manhole cover of the manhole pipe which passes through it. Electrical cables are routed inside the connection unit, which lead to a fixed connection of the connection unit, into which a cable can be inserted from the outside. DE-C 1 044 921 relates to a connection device for electrical power consumers which can be lowered into the ground. For this purpose, a cylindrical column element is provided, in which a connecting cable leads to a fixed connection, into which a connecting plug can be inserted from the outside.

A switch box arrangement according to DE 92 70 542 Ul has a lowering unit of cylindrical geometry which has a fixed connection for an electrical cable which can be inserted from the outside. A corresponding construction can be found in US 3,646,244. In this case, a housing having a cylindrical shape can be lowered into or raised from a shaft to the required extent. Plug receptacles are located in at least one outer wall of the housing, for plugs that can be inserted from the outside.

The present invention is based on the problem of developing a supply device of the type mentioned at the outset in such a way that, with a structurally simple construction, the desired lines or hoses for the care of aircraft emanate from it, which can be pulled out of the shaft to the required extent and thus can be moved relative to the column element are. At the same time, it should be ensured that when the column element is moved out, even if large-sized hoses are guided outwards through the supply arrangement, there is no danger to operators through existing openings. Furthermore, there should be the possibility of connecting a desired number of supply lines such as cables to a wide-body aircraft. According to the invention, the problem is essentially solved by the fact that the pillar element extends from a cover element that extends parallel to the bottom surface and closes the opening of the receptacle in the extended position of the pillar element, which can be pushed through by the at least one line or a hose and is relatively movable relative to it, in that the Cover element can be locked in the area of the opening of the receptacle and that the column element is a frame which has two longitudinal profiles and can be moved along guides running in the receptacle, which frame is connected to a counterweight guided along the guides and / or a drive. To lock the cover element, a lever, such as a foot lever, can extend from the free outer surface thereof, via which the cover element can be unlocked for the axial adjustment of the column element.

A particularly simple construction results when the column element can be moved along in telescopic guides or U-profiles. The plate or tube-shaped cover element starts from the longitudinal profiles received by the guides and, when the column element is pulled out, closes the bottom opening of the receptacle such as a shaft in such a way that - without hindering the routing of lines or hoses - there is no danger to operators ,

For this purpose, it is provided, inter alia, that the plate-shaped cover element has at least one opening delimited by a sliding guide, which opening can be penetrated by the at least one line, such as a supply cable. If the cover element is designed in the form of a frame, it delimits a rectangular or square inner opening which can be penetrated by a hose having annular or spiral inserts. The inner opening is adapted to the hose in such a way that there is no space between the edge of the opening and the hose to such an extent that an operator is at risk. A further proposal of the invention provides that in the plate-shaped cover element there is an opening, which is adapted to the tube and has a cross-section through it, the tube leading to a housing arranged above the opening, starting from the longitudinal profiles and having openings, through which fresh air can be drawn in is. The hose and the housing can be pushed into and out of the receptacle as a unit with the frame spanned by the longitudinal profiles such as square tubes.

As mentioned, the guides for the longitudinal profiles are preferably designed as telescopic roller guides, with sliding elements such as rollers running between the U-profiles and the longitudinal profiles mentioned by them.

Above the cover element and starting from the longitudinal profiles, a holder can be provided for a connector originating, for example, from a cable and / or an attachment originating from the hose. The holder is designed as a plate-shaped element running between the longitudinal profiles or comprises one. This ensures with structurally simple measures that the facilities required for supplying an aircraft, such as plugs, air or water connections, etc., are readily available, with the hose or cable stored in the receptacle in the floor, such as the shaft, being pulled out via the respective opening of the cover element can be done easily and with little friction and therefore gently. For this purpose, the openings of sliding elements such as rollers or rollers are limited.

In order to be able to supply, in particular, wide-bodied aircraft, the invention provides that at least two plugs extend from each side of the plate-shaped holder, the respective cable leading to a plug being stored in the receptacle separately from the other cables or being removable from the latter. For this purpose, in the receptacle as the shaft provided subdivisions, which are separated from each other by partitions such as wire mesh walls. In particular, the subdivisions are designed as storage baskets into which cables can be stowed separately.

The recording itself can be a hollow spherical body embedded in the base, which consists in particular of plastic material such as polyester material. The receptacle can also be designed as a passage or channel embedded in the floor, from which several supply arrangements may originate.

Further details, advantages and features of the invention result not only from the claims, the features to be extracted from them - by themselves and / or in combination - but also from the following description of preferred embodiments to be taken from the drawing. Show it:

Fig. 17 is a plan view of a receptacle designed as a shaft.

For example, a vehicle parked on a surface 10 such as a runway, such as an aircraft, which is in the parking position, with a voltage of 200 V / 400 Hz or 400 V / 50 Hz and / or compressed air and or water and or oil and or other energies or media To supply or suck in air from above the surface 10, it is known to let in a supply arrangement below the surface 10, via which the necessary lines or cables or connections are made available. In this respect, reference is made in principle to explanations as can be found, for example, in EP 0 664 254 BI or DE 37 43 393 C2.

The supply arrangement or a column element of this is slidably arranged in a shaft. The column element is basically vertically adjustable. The term "vertical" also includes a direction inclined to the horizontal. "Shaft" is to be understood to mean any recording, including a hollow sphere or a passage.

The necessary supply lines, cables and / or connections go out from the column element itself, in particular to supply an aircraft that positions on the runway 10 at different distances from the supply arrangement can be. It is therefore necessary that the line or the cable or the connection can be pulled off the column element to the required extent, that is to say it can be changed in length with respect to this.

The column element itself passes through a frame 12 which passes through an opening 14 in the receptacle and in the shaft. It is provided according to the invention that the supply arrangement - regardless of the particular embodiment - closes the opening 14 both in the lowered state and in the raised position to such an extent that there is no danger to operating personnel. However, this does not rule out the fact that, in particular in the raised position between the opening 14 and the supply arrangement, a - possibly larger - gap remains.

1 to 4 show a first embodiment of a supply arrangement 16 which, in accordance with the further exemplary embodiments, one of two longitudinal profiles 18, 20

formed raised or lowerable frame as the column member, which is displaceably displaceably supported in guides arranged within the receptacle such as the shaft, preferably in the form of U-profiles 22, 24 via sliding elements such as rollers 26, 28, 30. The longitudinal profiles 18, 20 are connected via cross struts 32. Correspondingly, the U-profiles 22, 24 are positioned aligned with one another via cross struts 34, 36. The guides are therefore designed in particular as so-called telescopic roller guides.

A rope 44 extends from two fixed points 40, 42 of the frame, which is guided over deflection rollers 46, 48 arranged in the bottom and in the head region of the guides and holds a counterweight 50 in order to facilitate the raising or lowering of the frame. In this respect, however, reference is made to well-known constructions. Alternatively or in addition, there is also the possibility of adjusting the frame along the guides by means of a drive such as a chain drive or spindle.

In the upper area 52 of the frame, that is to say that which protrudes above the surface 10 when the supply arrangement 16 or frame is raised, there is a holding plate 54 which runs between the longitudinal profiles 18, 20 and is fastened with these to accommodate, for example, panel plugs 56, 58 provided, via which an aircraft is supplied with power or the necessary signals. For this purpose, the panel connectors 56, 58 are removed from the holder 54 and inserted into a connector receptacle of an aircraft. Accordingly, a supply cable must be pulled out of the shaft, which is moved along the frame.

From the plugs 56, 58 therefore go out in Figs. 1 to 4 cables, not shown, which can be stored in the interior of the shaft. The cables penetrate a plate-shaped cover element 60, which has openings 62, 64 for the cables, which in turn are delimited by roller elements 66, 68 in order to enable the cables to be inserted or pulled out smoothly. The plate-shaped element 60, which starts from the longitudinal profiles 18, 20, has a planar extent such that when the supply arrangement or column element 16 is lifted off, the opening 14 delimited by the manhole cover 12 is covered or largely covered.

Furthermore, a lever, such as foot lever 70, emanates from the plate-shaped cover element 60, via which a lock can be released, by means of which the cover element 60 can be latched to the manhole cover 12, in order thus to either fix the column element 16 or its frame in a raised position or release. The latter occurs when the column element 16 is to be sunk into the receptacle or the frame such as the shaft.

In addition to the foot lever 70, a further unlocking element can be provided in the area of the mounting plate 54 in order to release the supply arrangement 16. A lid-shaped cover (cover) 72 extends from the head region of the longitudinal profiles 18, 20 and covers the opening 14 of the manhole frame 12 in the lowered position of the supply arrangement 16. For this purpose, the manhole frame 12 has a circumferential inner shoulder 75, the height of which is adapted to the cover 72 in such a way that the outer surface of the cover 72 is flush with or substantially flush with the outer surface of the manhole frame 12 and thus with the bottom surface 10. The frame 12 can be embedded in a cover closing the shaft.

The exemplary embodiment of FIGS. 5 to 8 differs from that of FIGS. 1 to 4 in that fresh air is to be supplied to an aircraft with a supply arrangement 74. Otherwise, the same elements are basically provided with the same reference numerals.

In order to make fresh air available, an annular or spiral-shaped insert (not shown) is provided, which can be pulled out of the receptacle or the shaft via an opening 76 of a frame-shaped cover element 78, which extends from the longitudinal profiles 18, 20 of the supply arrangement 74, or about this can be filed in the recording. The opening 76, which is matched to the outside diameter of the hose, is delimited by cylindrical roller elements 78, 80, 82 in order to make it easy to pull out or lower the hose. The hose then merges into a funnel-shaped connecting piece 84 which is detachably fastened to the holding or fastening plate 54 of the supply arrangement 74 or of the displaceable frame. If an aircraft is to be supplied with fresh air, it is only necessary that the connector 84 is removed from the holder 54 and then connected to an aircraft.

The planar extent of the frame-shaped plate element 78 is - in accordance with the exemplary embodiment of FIGS. 1 to 4 - adapted to an opening 86 in the manhole cover 12 such that in the raised state (FIG. 7) the cover element 78 closes the opening 86 or largely closes. In a further exemplary embodiment shown in FIGS. 9 to 11, a supply arrangement 88, the basic structure of which corresponds to that of FIGS. 1-8, is used for drawing in fresh air or venting the receptacle. For this goes from the Haltbzw. Fastening plate 54, which, as mentioned, is fastened to the longitudinal profiles 18, 20 of the supply arrangement 88, has a cuboid housing 90, in the side walls 92, 94 of which there are openings 96, 98, which are partially covered by lamellas 98.

A hose, not shown, which preferably has annular or spiral inserts and can be fastened to a frustoconical extension 100 of the housing 90 likewise leads to the housing 90. The hose then passes through a plate-shaped cover element 102 with an opening 104, which is designed for the outer diameter of the hose. The planar extent of the cover element 102 is - in accordance with the embodiment of FIGS. 1 to 8 - adapted to the opening of the manhole cover 12 penetrated by the supply arrangement 88 in order to close the opening when the supply device 88 or the column element is extended. Since the hose basically remains firmly connected to the extension 100, it is not necessary for the opening 104 to be delimited by sliding elements.

FIGS. 12 and 13 show configurations of a development of the embodiments according to FIGS. 1 to 4, the same reference numbers being used in principle for the same elements. In order to supply the required electrical energy from a single supply arrangement 106, in particular wide-body aircraft, a total of 4 panel connectors 56, 58, 108 extend from the holding plate 54, the cables 110, 112, 114 leading to the connectors 56, 58, 108 in areas 118, 120, 122 separated from one another within the receptacle, such as the shaft 116 of the supply arrangement 106, can be stored in storage baskets or can be removed therefrom. This ensures that complex guides for the cables 110, 112, 114 are not required, since the cables 110, 112, 114 are guided separately from one another regardless of the position of the frame, that is to say the position of the holding plate 54 and thus entanglement is not possible.

Of course, it is not necessary for the plugs 56, 58, 108 to extend directly from the plate-shaped holder 54. Rather, there is also the possibility without further ado that the plugs 56, 58, 108 start from halving, which are fastened to struts 124, 126, which in turn are connected to the longitudinal profiles 18, 20 which form the frame. An emergency stop switch 130 and / or a signal lamp 132 can also emanate from the plate-shaped holder 54.

14 to 16 show further preferred embodiments of the teaching according to the invention. The supply arrangement shown in FIGS. 14 and 15 corresponds in principle to that shown in FIGS. 1 to 4. However, it is made clear that the cables 110, 122 leading to the plugs 56, 58 are each stowed in a storage basket 118, 120, which ensures that the cables 110, 112 do not interfere with one another.

The plugs 56, 58 themselves emanate from the plate-shaped holder 54, in the upper region of which the emergency stop switch is present immediately below the cover 72.

The cables 110, 112 are passed through the openings 62, 64 delimited by the sliding rollers 66, 68 in a sliding and thus gentle manner. The sliding guides start from the plate-shaped element 60 on which the foot lever 70 is located.

The U-profiles 22, 24 forming the telescopic roller guides are connected to profile elements 133, 135, which in turn are connected to the bottom 136 of the shaft 116 via base plates 134.

One of the supply arrangements 138 shown in FIG. 16 is designed to supply an aircraft not only with electricity but also with compressed air and also to provide a grounding cable. Regarding the power supply is the Arrangement 138 designed in accordance with that of FIGS. 14 and 15, ie the cables 110, 112 can be stowed in separate receptacles such as storage baskets 118, 120. Above the storage baskets there are additionally spring-loaded coils 140, 142 and 144, 146 in the receptacle of the supply arrangement 138 designed as a shaft 148, from which compressed air hoses or grounding cables can be pulled off and can be automatically rolled up by the coils 140, 142 and 144, 146 when not required , Otherwise, the supply arrangement 138 has a structure which corresponds to that of the supply arrangement of FIGS. 1 to 15.

FIG. 17 shows a plan view of a shaft 150 in which supply arrangements corresponding to FIGS. 1 to 16 can be arranged. The shaft 150 has five separate receptacles such as baskets 152, 154, 156, 158 and 160. The receiving baskets 152, 154, 156, 160 starting from the corners are intended for storing or removing cables. The receiving basket 158 between the holding baskets 156 and 160 shown on the right in the drawing serves to hold a supply hose, in particular to supply water to an aircraft.

Between the receiving baskets 152, 154, 156, 158, 160, the telescopic roller guide with the column elements slidably received by it is arranged in order to be able to lift cables or hoses over the surface of a runway, so that an aircraft can be energized to the desired extent , Water, compressed air, oil or other media can be supplied.

Typical ratings for the framework of the supply arrangement are:

Length of the longitudinal profiles: 2,000 - 3,000 mm

Distance between the longitudinal profiles: 500 - 1,000 mm surface extension of the plate element: 0.25 m ² to 0.4 m ² .
