Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application/?) The present invention relates to a conveying device for ships for transporting loads having a vertical conveyor formed as a spiral conveyor, more particularly to The present invention relates to a conveying device for a ship having a vertical spiral conveyor, which is equipped with conveying belts at its lower and upper ends for transferring bulk cargo, etc., respectively.

(Prior Art) German Published Application No. 2824505 discloses that for the vertical transfer of bulk loads, a spiral conveyor is arranged as follows, i.e. approximately horizontally; It is known to provide transport segments with surfaces. In this case, various disadvantages arise. For example, because it is necessary to return the transport segment to a horizontal position, a spiral conveyor is provided with an upper belt and a lower belt. A relatively large number of transport segments with drive mechanisms are then required. The large number of drive mechanisms means, on the one hand, high costs and, on the other hand, high wear parts. Additionally, support is required at the top and bottom of the structure of the transport segment, which is also costly.

German Published Application No. 28 33 449 discloses a vertical conveyor having a snake conveyor and an opposite supply or discharge conveyor, which is equipped with rubber belts for transporting bulk loads.

In the case of any of the above conveyors, a tensioning device is required. This structure requires multiple assembly and is expensive to maintain.

The conveying surface has special irregularities and is provided with a large number of horizontal guide rollers (Problems to be Solved by the Invention) Therefore, the problem of the present invention is to reduce the number of worn parts of the vertical conveyor. To provide a new type of ship conveying device for unloading bulk cargo, which can directly transfer cargo continuously without the need for transportation, has a large transfer capacity, and requires relatively low cost. It is in.

(Means for Solving the Problems) According to the present invention, the above problems are solved by the features described in the essential requirements of the claims.

That is, the device of the present invention is a ship having a vertical spiral conveyor, which is equipped with a vertical central pipe and a respective transfer belt for transferring loads such as bulk loads at the lower end or upper end of the central pipe. In transport equipment, from the lowest position of the ship's hatch to the highest unloading position,
Inside the two guide rails (4, 8) which are arranged in a spiral manner around the vertical central eve, the guide rails (4, 8) are laterally supported and relatively closely arranged in the entire area of the spiral guide rails. A drivable carrier (2) is arranged
, and is characterized by being provided with a node (3) or something similar for transferring bulk loads.

Other preferred embodiments are described in the dependent claims.

(Example) The present invention will be described in detail below using examples shown in the drawings.

The device is provided with driveable carriers 2 arranged in relatively close succession, primarily in a helical guide in the ascending direction, these carriers being arranged one or more times in the area of a vertical conveyor 1. The carrier 2 is rotatably driven via multiple chains, and the surface of the carrier 2 is provided with joints 3 or similar devices installed at predetermined intervals, and the bulk load is moved forward through these joints. This is to prevent it from slipping back down.

Two guide rails 4 and 8 are arranged spirally around the central paigua from the lowest position to the highest unloading position of the hatch part of the ship. In these guide rails there are disposed roller-shaped carriers 2 which are mounted laterally and closely side by side in the entire area between the guide rails; It is rotatably supported on a shaft that is firmly stretched on both sides.

The carriers 2 arranged in succession move within the guide rails 4, 8 of the vertical conveyor 1 in a circle 2[t] from one side 8 of the guide rail to the other Ill 4 of the guide rail.

A conical ring device is provided in the shape of a cylinder or in the form of a cylinder.

On the ship's side, the bulk load is automatically conveyed via the lower belt conveyor 5 to the vertical conveyor l, and the bulk load is transported forward (upwards) via carriers 2 driven in the vertical conveyor O. ) and transported to an upper delivery location, where the bulk cargo is transferred to an upper belt conveyor 6.
This is done automatically via .

In this case, a large number of carriers 2 are required. As confirmed by experience, such carriers are not wear parts, are continuously lubricated and have a long service life due to their sturdy construction. Additionally, the carrier is standardized as a conveyor belt carrier, which keeps costs relatively low. As a result, the following surprising technical effects can be obtained. Thus, compared to known vertical conveyors for conveying bulk loads, the relatively simple and advanced construction according to the invention provides better results not only in terms of cost and operation, but also in terms of efficiency.

Other advantages include a less noisy structure. This is because very good results are obtained when the carrier is made of plastic and when special working methods in acoustic technology are used.
