Device for filling a tanker vehicle

The invention relates to a device for filling a tank vehicle with fluid media, in particular fuels, whereby the tank vehicle has connecting pieces arranged at a distance from one another on or near the bottom of its tank, which has several filling chambers, along the length of the vehicle, and the device consists of at least one, preferably several, multi-part filling pipes designed to be pivotable and rotatable, which is connected at one end to a stationary tank system and at the other end has a connecting coupling for coupling to a connecting piece of the vehicle, whereby the filling pipe also passes from the connecting coupling via at least one first pipe bend into a connecting hose or a first straight pipe section, the connection of which to the pipe bend is made by a

Jahnsdorf 10329/91

first pivot bearing is formed with a rotation axis coaxial with the connecting hose or pipe section, wherein the connecting hose or the straight pipe section passes over a further, second pipe bend into a further, second straight pipe section, to which a third pipe bend is connected, to the outlet of which a further, fourth pipe bend is connected via a second pivot bearing, to the outlet of which a connection is made to a hanging or standing column of the stationary tank system, which is connected to the respective storage tank, via a further, third pivot bearing, wherein when several filling pipes are arranged at a filling station, the height or length of the column, the pipe sections and, if applicable, the connecting hose are coordinated with one another in such a way that, with pipe sections, columns and connecting hoses running parallel to one another, a free pivot path is formed when pivoting around the center hole axis of the columns.

Such devices are known in the art. They are usually referred to as

Jahnsdorf 10329/91

"BOTTOM-LOADING SYSTEM" is offered. Two versions are known from the state of the art. In a first version, a bottom-loading system is connected to the connection piece of a standing or hanging column, which is connected in a suitable manner to a storage facility for liquid fuels, for example fuels, via a

The state of the art also includes a device

-U-

known, in which, starting from the column-side connection piece, there is again a pivot bearing with a vertical axis, a pipe section, a pipe bend bent at a right angle with a horizontal outlet axis, followed by another pivot bearing with a horizontal axis, followed by a pipe bend (right angled) with two outlets lying in a horizontal plane, followed by another long pipe section, followed by another right angle pipe bend with a horizontal outlet axis, followed by another pivot bearing with a horizontal axis of rotation, and from this a pipe bend (right angled) with a downward-pointing outlet is arranged, whereby, instead of a flexible hose, another relatively long rigid pipe section is attached to this pipe bend, which has the connection coupling at the end, where the connection coupling is arranged with two further pipe sections and two further pivot bearings interposed with an intersecting axis. All connections are designed to be liquid-tight and suitable for the passage of the corresponding fluid medium. It is common to use such devices multiple times,

Jahnsdorf 10329/91

for example six times, next to each other in the form of a filling battery, since the usual tank vehicles have different compartments for the different types of fuel or the like, which can be filled simultaneously or one after the other. For example, these are compartments for regular unleaded petrol, premium unleaded petrol, particularly high-octane premium unleaded petrol, leaded premium petrol, and diesel fuel. The connection nozzles for the connection couplings arranged on the tank vehicle are located at the same level and at a distance from each other in the floor area of the tank of the tank vehicle, whereby all of these connection points must be accessible via the corresponding connection couplings of the filling device. It cannot be avoided that the filling pipes are arranged so that they cross each other. In the devices according to the above-mentioned state of the art, in the embodiment with a connection hose, this connection hose must be connected diagonally at a solid angle, crossing the paths of the other connection hoses, to the corresponding connection

Jahnsdorf 10329/91

nozzles. Even with the arrangement of a pipe section instead of the connecting hose known in the prior art, an arrangement of the pipe section at a spatial angle cannot be avoided. This leads to confusing handling and is also confusing and complex to operate. In the arrangement according to the prior art, it is already provided for in these multiple batteries that the connecting nozzles of the hanging or standing columns have different heights so that the swiveling of the filling pipes is not hindered by the neighboring filling pipes. For this purpose, it is also usual for the lengths of the individual pipe sections of the filling pipes to be longer or shorter to match the corresponding swivel path.

Based on this state of the art, the invention is based on the object of creating a device of the generic type in which, even with a crossing arrangement of the pipe sections extending from the columns, an at least essentially vertical arrangement of the

Jahnsdorf 10329/91

the pipe sections passing through the connection couplings is possible.

To solve this problem, it is proposed that a third pipe section with oppositely angled pipe bends be inserted between the third pivot bearing and the connecting piece of the column, which is connected to the connecting piece of the column via a fourth pivot bearing, which has an axis of rotation parallel to the third pivot bearing.

This arrangement enables a quasi scissor-like movement between the second and third pipe sections, which enables the necessary length compensation, particularly when the pipe sections of adjacent columns cross each other, which results in the first pipe section or the hose leading to the connection coupling running essentially vertically when connected to the connection point of the tank vehicle. This design not only makes operation easier, but also

Jahnsdorf 10329/91

The connection system is also designed to be more clearly laid out. The inclination (spatial angle) of the first pipe section that was previously required in the state of the art to reach a corresponding connection point on the tank vehicle is no longer necessary.

The overall structure of the device has not become more complicated, and the additional advantage is that when the filling process is complete, the filling pipes of each individual filling line can be arranged relatively closely packed on the filling device by pivoting the third and second pipe sections together.

Preferably, all pipe bends form the same angle, in particular 90°.

This training is in itself common practice in the state of the art.

Furthermore, it is preferably provided that a weight held on the fourth pipe bend is

Jahnsdorf 10329/91

balancing device is arranged to attack.

Such a weight compensation device is also known in the prior art, but it is then clamped between the second pipe section and the pipe bend adjacent to the column.

An advantageous design, which is particularly preferred in the case of a rigid first pipe section instead of a hose, is that the first pipe section is connected to the second pipe bend via a flow-through joint ball.

This joint ball creates a swivel joint and a swivel joint with a limited swivel angle, which allows a slight, if appropriate, inclination of the pipe section. This inclination is necessary if the connection coupling is not exactly coaxial with the corresponding connection point of the tank vehicle, but must be aligned with it. In the state of the art, this was previously a

Jahnsdorf 10329/91

Arrangement of two pipe bends with two swivel joints with intersecting axes of rotation required.

Preferably, it is further provided that the first pivot bearing is arranged between the first pipe section and the second pipe bend.

If a hose-shaped element is used instead of the rigid first pipe section, only a first pivot bearing is to be provided instead of a joint ball, which is arranged between the hose outlet and the pipe bend leading to the connection coupling.

A corresponding coaxial alignment of the connection coupling relative to the connection point is possible due to the flexible design of the hose.

An abstracted embodiment is seen in that the third pipe section can only be pivoted relative to the column-side connection piece around a vertical axis, the second pipe section relative to the

Jahnsdorf 10329/91

third pipe section is also pivotable about a vertical axis and about a horizontal axis directed transversely thereto and the first pipe section is rigidly attached to the second pipe section, including a right angle, is optionally rotatable about an axis directed coaxially to the first pipe section and an axis directed transversely thereto is attached so as to be pivotable to a limited extent.

Preferably, the length of the third pipe section is approximately the same, preferably slightly shorter than the length of the second pipe section.

Furthermore, it is provided in a manner known per se that the relative height of the connecting pieces of the columns in the case of multiple arrangements of columns of a device next to one another is graduated so that the pivoting ranges of the connected filling pipes run along one another without overlapping.

The device for filling a tanker 1, for example with carburetor and diesel fuels, is clearly shown in the drawings. The tanker 1 has connecting nozzles 2 arranged at a distance from one another on or near the bottom of its tank, which has several filling chambers, along the length of the vehicle. In the exemplary embodiment, the device has several multi-part filling pipes 3 that are designed to be pivotable and rotatable. Each filling pipe 3 is connected at one end to the stationary tank system, while the other end has a connecting coupling 4, optionally with a backflow preventer 5. The filling pipe 3 consists of a pipe or hose system, with a first pipe bend 6 (at right angles) extending from the connecting coupling 4, with one of its outlets lying horizontally in the position of use and merging into the central axis of the coupling piece 4, while the central axis at the other end is vertical. This end of the first pipe bend 6 merges into a connecting hose 7, whose connection with the pipe bend 6 is established by a first pivot bearing 8 with

Jahnsdorf 10329/91

to the connecting hose 7 or pipe section end with a coaxial axis of rotation. The coupling piece 4 can thus be rotated around this vertical axis of the connecting hose 7. The connecting hose 7 passes over a further, second pipe bend 9 into a second straight pipe section 10. This pipe section 10 is usually aligned so that its central axis runs horizontally. A third pipe bend 11 is connected to the straight pipe section 10, both of whose mouths are horizontal. A further, fourth pipe bend 13 is connected to its outlet via a second pivot bearing 12, the free mouth of which points vertically upwards in the drawing Figure 1. A further, third pivot bearing 14 with a vertical axis of rotation according to the drawing Figure 1 is connected to this mouth. A third pipe section 15 with oppositely angled pipe bends 16 and 17 is connected to the third pivot bearing 14, which is connected to the connecting piece 19 of a hanging or standing column 20 via a fourth pivot bearing 18. The fourth pivot bearing 18 has a vertical axis of rotation just like the third pivot bearing 14. The column

Jahnsdorf 10329/91

20 is part of a stationary tank system that is connected to the respective storage tank. As can be seen in particular from Figures 3 and 4 and in the other embodiment from Figures 7 and 8, the arrangement of several filling pipes 3 at a filling station is provided, whereby the height and length of the column 20 as well as the pipe sections 10 and 15 and the hose 7 are coordinated with one another in such a way that when the pipe sections, columns and connecting hoses are aligned parallel to one another, a free pivoting path is formed when pivoting around the central vertical axis of the columns 20. This is particularly clear from Figures 3 and 4. In the embodiment according to Figures 5 to 8, a rigid pipe section 7' is arranged instead of the connecting hose 7. The first pivot bearing

8 are omitted and instead a joint ball 21 between the pipe section 7' and the second pipe bend

9. The joint ball 21 enables the rotation of the pipe section 7' around its vertical axis as well as the pivoting (at a limited angle of approx. 15°) around the joint formed by the ball 21.

Jahnsdorf 10329/91

In all embodiments, a weight compensation device 22 is provided on the second pipe section 10 and on the fourth pipe bend 16, which can in principle be designed in any way. For example, this can be a simple balancing weight. It is also possible to arrange hydraulic or pneumatic working cylinders as weight compensation devices.

In order to create the appropriate free swivel space between adjacent filling pipe systems, the lengths Ll, L2 and L3, which are indicated in Figure 6, for example, must be coordinated with one another. As a rule, the length Ll (length of the third pipe section 15 between the swivel joints) is somewhat less than the length L2 (length of the second pipe section 10 between the swivel joints), while the length L3 (length of the first pipe section 7' or the hose-shaped connecting element 7 between the parallel pipe axes (measured from the second pipe section 10 and the connecting piece A) is considerably greater and must be coordinated with the corresponding

Jahnsdorf 10329/91

corresponding connection height of the connection element 19 on the column 20. The height gradation between these elements is usually approx. 500 mm. The lateral distance between the columns 20, as can be seen in particular from Figure 7, is also usually approx. 500 mm. The distance between the connection nozzles of the tank truck is usually approx. 350 mm.

The design according to the invention ensures that the third pipe section 15 can only be pivoted relative to the connecting piece (19) of the column 20 about a vertical axis that is formed by the fourth pivot bearing 18. The second pipe section 10 can also be pivoted relative to the third pipe section 15 about a vertical axis (formed by the third pivot bearing IA) and about a horizontal axis that is directed transversely thereto (second pivot bearing 12). The first pipe section 7' or the connecting hose 7 is either rigidly attached to the second pipe section 10, including a right angle, extending relatively vertically downwards, or about an axis that is directed coaxially to the first pipe section 7'.

Jahnsdorf 10329/91

th axis (by means of the ball joint 21) and at the same time can be pivoted to a limited extent about an axis directed transversely to it (also by means of the ball joint 21). In drawing figures 3 and 4, the first embodiment is shown in the pivoted-in position (figure 3) and in the pivoted-out position (figure 4). In the pivoted-in position according to figure 3, the entire device requires only a relatively small amount of space, so that a space-saving arrangement is achieved despite the large boom width.

Figure 4 shows how the arrangement is aligned with a stretched filling pipe with maximum projection. A similar comparison can be found in Figures 7 and 8 for the second embodiment. The particular advantage is that even if the second and third pipe sections 10, 15 of one device are arranged crossing the adjacent pipe sections 10, 15 of another device, a largely right-angled alignment of the pipe sections, in particular also of the first pipe section 7 ¹ or the connecting hose 7, is possible, so that unmistakable

Jahnsdorf 10329/91

visible and difficult to manage spatial angles of intersecting cables are avoided.

The invention is not limited to the embodiments, but is variable in many ways within the scope of the disclosure.

All new individual and combination features disclosed in the description and/or drawing are considered essential to the invention.
