Definitions

  • the present invention concerns a protective device for storage rooms or cargo holds, especially on ships. It comprises a flexible cover arranged on the hold's coaming. In the cover there is an opening for introducing and connecting a loading/unloading device.
  • Norwegian patent application No. 882272 shows another arrangement for covering a loading hatch. It comprises a cover fastened to a circular ring with a central opening for a loading channel which can be moved radially within the ring.
  • the arrangement will automatically produce a considerable amount of dust on the lower side of the construction and this will lead to coating on the wheel track. This will again demand a relatively large force for rotation.
  • the loading/unloading system cannot be easily steered to any position in the cargo hold and the system's pattern is locked to the construction itself. Consequently this leads to relatively large dead sectors in the corners.
  • French patent No. 2.457.214 shows the use of rectangular hatch coamings and a square hatch cover.
  • the hatch cover is fitted with a smaller square opening which can be moved into different positions within the area of the square hatch cover.
  • the other parts of the cover are automatically covered by foldable canvas material.
  • a number of telescopic arms are required in addition to a complicated linkage arrangement and the necessary pressure cylinders.
  • the hatch cover can be moved from hatch opening to hatch opening and must be readjusted from position to position in each hatch opening.
  • the above-mentioned hatch cover is fairly heavy and it is difficult to readjust from position to position.
  • the main object of the present invention was to develop an improved device for protection against dust emissions when load ⁇ ing/unloading bulk goods and which at the same time protects the goods against water penetration during precipitation.
  • the device should be simple and operationally reliable, among other things with regard to the loading hatch's dimensions.
  • Another object was to produce a protective device which was easy to operate, either manually or remotely.
  • the object was to design a device which was flexible with regard to the choice of equipment for transportation of bulk goods into or out of the cargo hold.
  • a frame was located between the cover parts in the former part for introducing the actual loading/unloading device, also called the loading shaft, which can be extended telescopically.
  • the loading shaft can be arranged in a dust-tight manner in the cover, for example by using a flexible canvas sheet which covers all of the loading shaft and which is fastened to it and to the frame in the cover stated above.
  • rollers would have to be driven mechanically and the operation of the rollers would be coordinated for the cover parts which were moved for ⁇ wards/backwards in the same direction. It proved possible to achieve a dust-tight, movable cover by using two sets of rollers with independent operation of the two sets of rollers.
  • the cover was located in a frame which could have dimensions corresponding to either the whole hatch opening or to parts of it.
  • This frame could be placed lengthwise or crosswise on the hatch opening but preferably crosswise as hatches are usually covered with transverse weather covers divided up into a number of parts.
  • just one of the weather covers is removed and the frame with the protective cover according to the present invention is placed over this opening.
  • the weather covers are opened/closed and the above-mentioned frame is moved accordingly which enables loading/unloading to take place over the full area of the loading hatch. In this way dust-free loading/unloading is possible all the time.
  • the protective device according to the present invention is not restricted to a particular choice of materials for the cover parts; the only requirement is that it must be able to be fed onto/off a roller and also prevent dust emission and/or penetra ⁇ tion of water into the bulk goods.
  • the rollers can be operated electrically via gears, chains etc. and safety couplings on the individual rollers.
  • the dimensions of the cover can be adapted to all types of square or rectangular hatches or loading/unloading openings, either on ships or in stationary bulk storage areas.
  • Fig. 1 shows the protective device seen from above.
  • Fig. 2 shows the protective device seen from the side.
  • Fig. 3 shows a loading/unloading device for connection to the protective device itself.
  • Fig. 4 shows the protective device positioned on a loading hatch on a ship.
  • Fig. 1 shows a protective device S comprising flexible cover parts 5a and 5b which can be rolled on and off the rollers A and B arranged at the ends of two parallel, longitudinal main frames 9. Between the two frames 9 and at right angles to them are mounted two parallel frames 2 which can be moved lengthwise along the main frame 9 as the frames 2 are fastened to the cover parts 5a and 5b. During such movement the cover parts 5a and 5b will be rolled either onto/off the rollers A and B.
  • the flexible cover parts 6c and 6d are arranged between the frames 2; they can be rolled onto/off rollers C and D at the ends of the two parallel frames 2. At their other ends cover parts 6c and 6d are fastened to a frame 3 with a central opening 4 for the introduction and connection of a loading/unloading device 8 shown in figure 3.
  • Fig. 2 shows the cover S seen in cross-section and placed over a hatch 10 with hatch coamings 7.
  • Fig. 4 shows the cover S according to fig. 1 placed crosswise on a hatch 10 of a ship 11.
  • the cover S covers just a part of the hatch opening while the remaining part of the opening is covered by weather covers 12 which can be removed or moved by folding as the device S is moved along the hatch 10.
  • the device S can cover the whole opening.
  • the present invention represents a protective device which efficiently prevents dust emission and/or water penetration when loading/unloading bulk goods. Using the device produces a minimal reduction of the loading/unloading capacity and allows access to the whole circumference of the loading hatch so that there are no dead zones, which some other devices produce.
  • the protective device is simple to operate and its design is so simple and light that it can easily be disconnected from one hatch and moved to the next. It can be used in conjunction with various loading/unloading devices, even telescopic ones.
  • the device according to the present invention can easily be mounted permanently on/in a hatch coaming. This is of particular significance on large bulk ships.
  • the device can be mounted underneath weather covers.
  • the device makes it possible to use simple apparatus for returning filtered dust to the cargo hold and consequently no dust is let out into the environment during loading/unloading.

Abstract

L'invention concerne un dispositif de protection pour salles de stockage ou soutes de cargaison (10), surtout dans les navires (11). Le dispositif est constitué d'une couverture souple (5) disposée sur la hiloire (7) de la soute et possède une ouverture (4) pour l'introduction et la fixation d'un dispositif de chargement/déchargement (8). Le dispositif de protection comprend un cadre principal (9) doté de parties de couverture (5a, 5b); un cadre transversal (2) est monté à l'intérieur du cadre principal (9) entre les parties de couverture (5a, 5b); le cadre transversal (2) peut être déplacé dans le sens longitudinal (a, b) le long du cadre principal (9) vers les extrémités transversales du cadre principal (9). Dans le cadre (2), entre les parties de couverture (6c, 6d), se trouve un cadre (3) dans lequel l'ouverture (4) peut être déplacée à l'intérieur du cadre (2) transversalement à l'axe longitudinal du cadre principal (9). Une extrémité de chacune des parties de couverture (5a, 5b) est fixée au cadre (2), et aux autres extrémités respectives elle est fixée à des rouleaux (A, B) disposés à l'une des extrémités transversales du cadre principal (9). Des parties de couverture (6c, 6d) sont fixées, par leurs extrémités respectives, au cadre (3) et, par les autres extrémités respectives, à des rouleaux (C, D), disposés à l'une des extrémités transversales du cadre (2) par le cadre principal (9). Les parties de couverture (5a, 5b) peuvent être montées sur les rouleaux respectifs (A, B) et démontées de ceux-ci, et des parties de couverture (6c, 6d) peuvent être déplacées dans un sens transversal par rapport au cadre principal (9) pour être montées sur les rouleaux respectifs (C, D) et démontées de ceux-ci, indépendamment du mouvement des parties de couverture (5a, 5b).
