"Device for monitoring the position of a connection end of a land-based ship loading device"

The invention is directed to a device for monitoring the position of a connection end of a land-based Ship loading device with rotating and swiveling extension arms.

When attaching a connection end of a land-based Ship loading device with rotating and swiveling extension arms, especially for liquid or gaseous goods, If possible, the connection end on the ship should be made in an area that allows for comparison still allows large ship movement without the loading equipment running at risk, via a safety device, i.e. a quick disconnect to be disconnected from the ship. This is particularly necessary because the ships to be loaded or unloaded sink or rise as they become heavier or lighter and a certain amount Must be able to follow wave motion. The loading device itself must also compensate for different water levels can and the like more.

In one written by the applicant together with P. Schubert Article "New Security Ship Loading System", OEL magazine for the mineral oil industry May 1976, page 163 ff., are the theoretical bases of the S chi ff s'-

areas of loading movement discussed. A rendering of the essential thoughts of this older publication can be found below in the special description.

So far one has proceeded with the coupling of the connection end usually so that a limit switch or the like. When a certain angle of the cantilever arm is exceeded An acoustic signal sounds for the fitter making the connection to make it clear to him that he by installing extension pieces or the like. The connection end must be installed in a different position on a corresponding connection on the ship. A Such a system does provide certain security, but it only enables borderline situations to be recorded.

In contrast, the object of the invention is to create a solution with which, in particular, a monitoring person is put in a position to be able to visually understand exactly at any time at which point the connection, final is located exactly during assembly and during the loading and unloading process in order to prevent / to be able to bend.

With a device of the type indicated at the outset, this object is achieved according to the invention by means of angle measuring devices to determine the respective angular position of the extension arms in the horizontal and vertical Level, by an arithmetic unit for converting the from

the angle measuring devices given information in connection with given by the geometry of the cantilever arms Plague values and determination of the current state of the Connection end in the room as well as through an optical display unit to visualize the current state solved a screen.

Further advantageous' embodiments of the invention Device emerge from the subclaims, wherein it is particularly expedient, if possible, only the To make the position of the connection end optically visible on a viewing device in one plane and then one on this plane to assign the corresponding height information. This means that an outside observer can also measure the height of the Monitor the loading deck of a ship relative to the quay and, for example, accurately monitor only partial loading of a ship control if, for example, a tanker basically has a much greater low level when fully loaded, than local conditions allow. For example, a tanker with a draft of 24m can be used A loading quay, which only allows a 12m draft, can be loaded and the cargo can be monitored until it is straight permissible draft has been reached.

Further features, details and advantages of the invention emerge on the basis of the following description as well as based on the drawing. This shows in

Fig. 1 the spatial, simplified reproduction of a cantilever arm with details of the angle measurement ranges, the simplified computer and a screen reader, as in

2 an indication of the ship loading device movement areas, as it is also shown in the article mentioned at the beginning.

A ship loading facility is located on a shore quay 1 2 arranged with rotatable and pivotable cantilever arms 3 and 4, on which a further mounting socket 5 with possibly further elbows and the like, as well as the connection end 6 carrying a valve is mounted.

To determine the angular positions of the individual elements with respect to one another, in particular also with respect to the stationary base I ₃ , angle measuring devices 8 are provided on the ship loading device 2 in the area of the boom, which are indicated in FIG. 2 as pipe couplings. These angle measuring devices 8 are designed, for example, as electrical resistance measuring devices in order to supply the respective measuring and angular position to a computing unit 9, which is indicated by a line 10 with three lines in FIG.

The arithmetic unit 9 has stored fixed values, which are e.g. Column 7 from the quay front edge and the like. Are determined. the

Angle measuring devices 8 transmit, for example, the angle "<Z" as the angle between the vertical "z" and the boom 3, the angle ¹ WS "as the angle between the boom 3 and the boom 4, the angle " γ "" as the angle between the front edge of the quay as a straight line "x" and the cantilever ^{arm portion 3 1} in the horizontal plane "x, y" and for example the angle "cT between the cantilever arms H and 5. By appropriate conversion and linking with the Pest values, the arithmetic unit 9 is able to determine the exact position of the connection end 6 in space and to feed it to an optical display unit 11 with a screen 12.

The arithmetic unit 9 can, for example, be in Pig. 2 reproduced Incorporate specially marked areas into the diagram, with the areas marked as follows are :

13 denotes the connection area, ie the partial area of possible free work in which the connection of the loading device to the ship flange is to be made. Ik represents the work area in which the ship connecting flange can move freely during the loading or unloading process without danger. 15 identifies the warning area in which the ship connecting flange can just barely move freely without the freedom of movement of the loading device being significantly restricted. The reaching of the warning area 15 should be known on the monitor 12.

borrowed and possibly also acoustically, as is known, indicated to the operating personnel. Finally, 16 represents the separation area, ie the area in which a rapid separation between the loading device and the ship is initiated, with 17 indicating the limit position resulting from the dimensions and technical designs of the entire loading device.

Of course, the described embodiment of the invention can be modified in many respects without the Leaving the basic idea of the invention, for example, in addition to a stationary screen display, this can also about the operating person, especially the fitter, who has the boom at its connecting end on the Assembled ship or leaked to other people working in the port on a mobile monitor or be identified, especially if the ship can not be fully loaded and the invention Device is used at the same time to monitor the level of a ship, as described above has already been described.
