DE20122116U1 - Freight loading system has distance between outer assembly tracks and center rail for fastening of smaller containers, and distance between outer assembly tracks of one pair and inner track of other pair for larger containers - Google Patents

Abstract

The freight loading system has two pairs of assembly tracks with support rollers, and a center rail for the attachment of transverse locks (25). The distance between the outer assembly tracks of each pair and the center rail corresponds to a first, smaller fastening spacing of a smaller container. The distance between the outer assembly tracks (30,30') of one pair and the inner track (31,31') of the other pair corresponds to a second, larger transverse fastening spacing for larger containers.

Description

The invention relates to a cargo loading system for Loading a cargo deck in a cargo hold of an aircraft.

Such charging systems are necessary to pallets, containers or similar standardized freight containers in to stow an airplane in such a way that the accumulation process quickly and is going on safely. By safe is meant here in particular that the cargo containers in their final Position within the cargo hold are fixed so that they cannot hike. The must System very easy to use, not to say "foolproof" as well-trained Freight personnel are often not available.

Another, especially here too treating problem is that despite the above requirements the cargo loading system cannot be designed to be complex, because every gram counts in air freight. Ultimately bring complex freight loading systems also the problem that with the number of parts the probability of Incidents increase.

Cross and longitudinal bars are used to fix the cargo container, for example, from the DE 198 54 189 or DE 198 08 659 known. Assembly tracks with roller drive units attached are, for example, from the DE 197 22 468.7 known.

The invention is based on the object Loading system for loading a cargo deck into a cargo hold To demonstrate that a safe stowing with simple means can be achieved.

This object is achieved by a charging system 1 solved.

An essential point of the invention is that with a minimized number of transportation and Fasteners in precisely defined row arrangements maximum number of congestion possibilities can also be achieved if the cargo hold is limited or due to internals (e.g. receiving areas for the chassis) at least in places is restricted.

So it will be the first one Task by a loading system for loading a cargo corner in one Cargo hold of an aircraft with pallets, containers or the like standardized freight containers solved, which includes:

• support rollers to support the cargo container and promote along a longitudinal axis of the cargo hold and the airplane; Roller drive units for driving the cargo container; Cross bar for attaching and locking the cargo container crossways to the longitudinal axis;
• longitudinal bars for fastening and locking freight containers in the direction of the longitudinal axis;
• two pairs of assembly tracks for assembling at least support rollers and crossbars;
• a middle row of crossbars and first and second rows of edge-side crossbars that are on the first or an opposite second outer edge of the cargo deck are mounted, the cargo containers being smaller cargo container (LD2) with a first, smaller cross-fastening distance and larger freight containers (LD3) with a second, larger cross-fastening distance include, each with a pair of assembly lines between the middle row and the first or between the middle mounting rail and the second row of edge-side crossbars is mounted and each pair of assembly tracks has an outer assembly track and an inner one Assembly line includes; being the distance between the outer assembly track each pair and the middle row and the respective assembled there Latching corresponds to the first, smaller fastening distance, and the distance between the outer assembly track of a pair and the inner assembly line of the other pair and the respective Crossbars mounted there correspond to the second, larger cross-fastening distance. you can with the charging system designed in this way the two different usual Types of standard containers fasten in various ways without therefore more than the above-mentioned tracks must be provided, which also narrows of the hold can be overcome are.

The outer assembly tracks are preferably trained for the assembly of crossbars on the edge. This will ensures maximum use of space.

The distance between each row of edge-side crossbars and the one closest to them inner assembly track and the crossbars installed there preferably the first, smaller mounting distance. So that can one (or two) narrower in a wider area of the cargo area cargo container can be stowed at the very edge of the hold.

Furthermore, the distance is preferred between each row of edge crossbars and the middle one Row of crossbars corresponding to the second, larger fastening distance educated. So it can be in a wider section of the cargo area a larger cargo container up to the extreme Be stowed away enough or be conveyed there.

The distance between each row of edge-side crossbars of the first or second row and the inner assembly track, the second and the first outer edge of the cargo deck is closer and the crossbars mounted there is the second, larger fastening distance trained accordingly. It can be combined with this arrangement in one narrower area of the cargo hold a larger cargo container as far as possible on The edge.

In a preferred embodiment the assembly tracks for the installation of roller drive units, as is known from the DE 198 54 189 is known. As a result, the floor of the cargo hold is kept clearly clear of roller drive units, which reduces the risk of injury and damage. Brake rollers or drainage systems can also be provided for draining the assembly tracks and / or the cargo deck.

In another preferred embodiment, which also in addition Recesses for installation can be used in the cargo deck provided by roller drive units, preferably between the assembly lines of the couples. Such roller drive units can with larger drive rollers for transportation heavier cargo container be formed.

After all, the assembly lines preferably also designed for mounting longitudinal bars, so that all for transportation and to fix the cargo containers necessary bolts and rollers can be accommodated in the assembly tracks.

In the description below be for the same and equivalent parts used the same reference numerals.

How out 1 are on or in a cargo deck 10 in the direction of a longitudinal axis X of the cargo deck 10 running a middle row 40 of elements (explained in more detail below) (essentially in the exact center of the cargo deck 10 ), and on each side of this a couple of assembly tracks, namely an outer assembly track 30 respectively. 30 ' and an inner assembly line 31 respectively. 31 ' arranged. In the assembly lanes 30 . 30 '; 31 . 31 ' as well as in the middle row 40 are support rollers 11 (see for example 2 . 3 . 10 ) provided, i.e. passive elements on which the objects to be transported can be moved with little friction. Furthermore are on a first edge 13 and a second margin 14 of the cargo deck 10 a row 50 respectively. 51 (please refer 15 ) of crossbars 25 and additional support rollers 10 appropriate. Such crossbars 25 are still in the assembly lanes 30 . 31 ; 30 ' . 31 ' and in the middle row 40 (there screwed directly onto the cargo deck or the beams below).

Known roller drive units are used to convey the objects 20 used, some of which are used in the 1 shown embodiment on one side of the middle row 40 to better illustrate the variability of the system in recesses in the cargo deck 10 between the outer assembly track 30 and the inner assembly line 31 are attached. On the other side of the middle mounting rail 40 are the roller drive units 20 inside the outer assembly track 30 ' appropriate. Alternatively or in addition, you can use the inner assembly track 31 respectively. 31 ' advantageously be attached. The main thing here is what type of containers and what weights or masses have to be conveyed.

In 2 a section through an aircraft is now indicated, from which it emerges that two larger transport containers 2 With a larger fastening distance b, completely fill the cargo deck, while doing so from the edge cross bars 25 and those in the middle row 40 attached crossbars 25 being held. The roller drive units 20 are in the outer assembly lanes 30 . 30 ' appropriate.

In 3 is shown as a single smaller container 1 can be protected against transverse slippage with its smaller fastening distance a, namely by clamping between the crossbars 25 that in an outer assembly line 30 or mounted on the outside, and crossbars 25 in the middle row 40 , The transport is done by roller drive units 20 which are both in the outer and in the inner assembly track 30 respectively. 31 are mounted. Such an arrangement can be chosen, for example, if between the outer edge 13 respectively. 14 and the outer assembly tracks 30 . 30 ' Obstacles, e.g. B. there are items mounted on the aircraft.

Out 4 shows that smaller containers 1 also between the bars 25 in the pair of edge crossbar rows 50 . 50 ' and the crossbars 25 that in the inner assembly tracks 31 . 31 ' are mounted, can be held because of the distance between these bars 25 the smaller fastening distance a of the smaller containers 1 equivalent.

Finally shows 5 that a larger container 2 with its larger fastening distance b between the outer assembly tracks 30 . 30 ' or the crossbars mounted there 25 and opposite, on the other side of the middle row 40 lying inner assembly tracks 31 ' respectively. 31 and the bars installed there 25 can be attached. Again it is (as with the arrangement according to 3 ) possible, containers and even the larger containers 2 to pass an obstacle mounted in the aircraft.

The assembly tracks 30 . 30 ' that are partially in the 6 - 10 are shown for receiving roller drive units 20 , Crossbars 25 (not shown here) and longitudinal bolts 27 educated. In addition there are support rollers 11 mounted in such a way that the containers can be moved without bumps. The longitudinal bars 27 are here over the entire length of the cargo deck 10 in the assembly lanes 30 . 31 ; 30 ' . 31 ' distributed so that a maximum density loading is possible. For this purpose, all longitudinal bars can be mounted in the assembly tracks 27 , Crossbar 25 and roller drive units 20 as well as support rollers 11 Can be moved in a grid (corresponding to the known seat rails) and fixed in a few simple steps.

From the 7 and 10 it is particularly clear that the support rollers 11 in the side panels of the assembly lines 30 . 31 are attached. The bars 27 are via bolts in perforated rails of the roller conveyors 30 . 31 attached so that they can be easily moved to predetermined locations and fixed there.

In the 11 - 14 is again more precise that in the 2 - 5 described matter shown, wherein in 11 a cross bar 27 a container 1 locked and in an inner assembly track 31 is mounted, as in the cutout of the 8th is shown. The 12 shows a section 2 , where the roller drive unit there under the bottom of a container 2 sits and in the outer assembly track 30 is mounted. Other such roller drive units 30 are installed in the other assembly lanes.

The 13 and 14 show excerpts 4 to represent how containers 1 on support rollers 11 rest with your floors and in assembly tracks 30 ' respectively. 31 ' are mounted.

In 15 is shown in more detail like containers 1 be arranged on the cargo deck and like the assembly lines 30 . 31 ; 30 ' . 31 ' pass under them, in which the components shown above, i.e. support rollers, roller drive units, longitudinal and crossbars are mounted. The crossbars 25 the middle row 40 are therefore not installed in separate assembly tracks but on the cargo deck 10 attached and in such a way that underlying stiffeners of the cargo deck are included, so the stability of the crossbars 25 to increase.

In 18 shows how smaller containers can be positioned. The cutouts according to 19 and 20 show how a longitudinal bar 27 sits between two containers, namely in such a way that its locking hooks projecting forward and backward (seen in the X direction of the cargo deck) (in 19 folded down) can capture two container edges. The positioning of the longitudinal bars 27 is done in a very simple manner by moving within the perforated rails of the assembly tracks 30 . 30 '; 31 . 31 ' ,

20 shows the in 15 designated section XX in an enlarged plan view to explain the arrangement of crossbars 25 and roller drive units 20 and the middle crossbar 25 with support rollers sitting next to each 11 ,

The above shows that with the proposed arrangement with light and variable assembly optimal loading of an aircraft is also possible if the cargo space is narrowed due to installation.
