The invention relates to an unloading device for a barge for bulk goods, the open loading space of which has a bottom sloping upward at one end towards a dispenser over which a by means of a cable or chain hoist drivable scraper for conveying the bulk material over the inclined section is guided to the dispensing device. Barges for bulk goods, e.g. B. for wet Sand, gravel, coal or the like are mostly unloaded with grab cranes set up on the pier. However, this harbors the risk that the swinging gripper will hit parts of the barge and damaged it. In addition, the acquisition, operation and maintenance of such a crane expensive. To avoid these disadvantages, it is known to use a device of the type mentioned at the beginning To operate genus that is carried by barge and unloading from the presence of a grab crane in the port makes it independent and protects the barge from damage, since the Scraper can be led straight and the risk is eliminated that he might hit the The side walls of the cargo space. In a known design of an unloading device according to The cargo hold of the barge is divided into the genus mentioned at the beginning, and each individual part of the The hold has a floor with an inclined floor section over which a excavator to a Funnel can be guided through which the bulk material is fed to an arrangement of additional conveyors. Compared to the procedure of unloading a barge for bulk goods described above however, this last known embodiment of an unloading device does not offer any by means of a crane notable advantage, because, apart from the fact that a separate excavator for each part of the hold must be provided, additional conveying equipment is required to get through the funnel to transport falling bulk goods to an unloading point of the barge. Here, too, are acquisition, Maintenance and operation expensive, and compared to the usual unloading of barges for bulk goods by means of a crane set up on the pier there is also the disadvantage that the extensive conveying equipment must be permanent fixtures on the barge, which are constantly be carried along and take up an otherwise usable part of the cargo space and the cargo weight to take.

The invention is based on the object of an unloading device of the type mentioned at the beginning designed in such a way that the transport of the in the unloading device for a barge

Bulk goods located in the hold from the hold to the point at which the goods enter the barge leaves without any change of direction in a single conveyor aisle. By solving this Already a new task in itself, it is made possible to get by with a single conveyor device, whose space requirement is limited to a minimum, so that no essential part of the usable cargo space and loading weight is lost in that the device is a permanent fixture in the barge must be carried. There are also no energy losses that are known in the aforementioned Training occur in that the goods are each from a conveyor to a sufficient high level must be promoted in order to get to the following funding in free fall. There are also no high acquisition, maintenance and operating costs. This task is carried out according to the invention achieved in that the bottom of the cargo space at its front end like a ramp is inclined upwards and an extension above the bow of the boat beyond the bow has a bottom opening arranged outside the bow tip as a dispenser for the Has bulk material, and that the cable of the scraper drive from the outer end of the extension to a machine arranged in the rear area of the boat to drive the cable pull extends in both directions.

The design of an unloading device for a barge according to the invention is characterized from the fact that compared to the aforementioned known training

809 537/53

The division of the cargo space into individual compartments with separate ramps and excavator equipment as well as a conveyor for receiving the bulk material conveyed by this is omitted. It In addition, an additional conveyor provided in the known training is omitted, which the picks up goods conveyed by the first conveyor and transports them further transversely to the axis of the barge. This also eliminates the need to unload the cargo along one side of the barge.

The advantages mentioned also characterize the design of an unloading device for a barge compared to a second known training, which also has a scraper over an inclined Section of the cargo space floor promotes. This is also the case with this known training The scraper conveyed the material inside the hull of the barge into a hopper that was quite lies deep below the deck of the barge and only serves as an intermediate container from which the cargo, in In this case, cement can be conveyed as required by means of a cement pump. Apart from this, So that even with this training conveyors, namely an intermediate container and a Cement pumps, which have to be carried on the ship as permanent fixtures and additional ones Causing costs for maintenance and operation, this known training is not general for bulk materials usable but only suitable for barges for the transport of cement.

An unloading device for barges according to the invention is, however, regardless of the type of the transported bulk goods can be used. The good to be cleared only needs by prospecting to be brought into the area of the floor opening provided as a dispensing device, the outside the tip of the bow, so that the material through the opening directly onto any conveyor on land or a heap falls. The barge only needs to be moored in such a way that the extension of the ramp section directly over a pier or the like. Sufficient. The funding agencies for onward transport of the discharged bulk material are not the subject of the invention. You are how in the known designs of unloading devices for barges, required anyway and in the Port available. It is also easily possible to extend the floor section inclined like a ramp trained so that it is at a high enough level to almost be used to allow any conceivable form of cargo unloading device, be it manual or mechanical, how they are available in ports.

In the drawing, a preferred embodiment of the invention is shown as an example.

F i g. Figure 1 shows a side view of the barge;

F i g. Figure 2 shows a plan view of the boat;

F i g. Figure 3 is a side view of the hold alone, showing only part of the outer ship structure is shown;

F i g. Figure 4 is a cross section taken along line IV-IV of Figure 4. 3, showing a major part of the external structure of the boat.

In the outer hull 1 of the barge, a loading space 2 which is open at the top is installed. This extends from the front end of the boat to the rear over a larger part, for example over three quarters or more, its length. The remaining part of the length of the boat is taken by the aft deck 3 with the Wheelhouse 4 and the other usual superstructures and the engine room below deck 3 5, (see Fig. 1). The cargo space 2 is chamfered in cross section, the Side walls 6 are flat and inclined inwards and downwards (cf. in particular FIG. 4). Runs at the stern he at 7 diagonally upwards to the quarterdeck 3.

The cargo space 2 has a level floor which at the front end at 10 gently into one at this end under about 30 ° upward leading ramp 11 passes. The ramp 11 is in an extension away, which protrudes over the bow of the boat in the direction of its axis. The bottom 12 of this extension is slightly inclined upwards and limited by low side walls 13. In the vicinity of the An outlet opening 14 is provided at the end of the ramp 12.

In the wheelhouse 4, a double drum winch 15 is provided with identical, mutually independent, coaxial and horizontally arranged drums. These drums are coupled to the drive shaft of the winch so that one of the drums can be driven to haul in, while the other is released by a slip clutch to give way. In the hold 2 there is a scraper 16. At the rear end of this scraper 16, a rope 17 is attached, which is guided over suitable guide rollers 20 to one of the drums of the winch, wrapped around it and attached to it. A second rope 18 is attached to the front end of the scraper 14 and, at the outer end of the extension 12, 13, is guided around one or more suitable pulleys 19, which are arranged on the other side of the floor opening 14. From there the rope is guided between guide rollers 20 a to the other drum of the winch 15. With this arrangement, the scraper 16 can be pulled forward by hauling in the one rope 18 by means of the one drum, so that it conveys bulk material over the ramp 11 to the extension 12, 13 thereof and to the floor opening 14. This drum is then released so that it can run idle and its rope 18 can yield. Then the other drum is coupled and fetches the scraper by means of the rope 17, whereupon a new conveying cycle begins. The ropes 17 and 18 run between the corresponding guide rollers 20 and 20 α , which are arranged in front of the winch and attached to the front wall of the wheelhouse.

If the bow of the boat is above the bank, a quay, a pier or the like, that can Material falling through the bottom opening 14 can simply be poured into a heap or, if necessary be fed through a filling chute to a conveyor belt or transferred to another ship.

In the illustrated embodiment with a self-propelled barge, the winch 15 can be driven by an electric motor 15 α and this can be supplied by an alternating current generator 21 which is driven by a main drive machine 22 of suitable construction arranged in the machine room. This drive machine can, for example, drive a water jet recoil drive 23 according to Gill (see FIG. 1). A suitable gear is provided to selectively reduce the recoil

drive or turn the alternator drive on or off.

As shown in FIG. 3 and 4 can be seen, the hold 2 is supported by transverse reinforcements 24, the form part of the outer hull, and surrounded by stiffening plates 25 and supported.
