Description

Ship hatch covers

The invention relates to a ship hatch cover with the hatch cover-side bearing element of at least one slide bearing arrangement, which also has a bearing element on the sill side and alignment means, the bearing elements lying flat on one another.

Such a ship hatch cover is known from DE 31 03 104 C2, in which, with the aid of a casting compound, a bearing element on the fill side, held in a receptacle, is pressed against a bearing element attached to the ship hatch cover. The disadvantage here is that the pressure of the potting compound pressed into the sill-side receptacle must be so great that the sill-side bearing and possibly also the associated part of the ship's hatch cover can be pressed upwards. A complex device for pressing in the casting compound is therefore necessary. Furthermore, in this prior art it is not possible to adapt the hatch-side bearing element to the position of the fill-side bearing element. A ship hatch cover is also known from DE 37 32 889 C1, in which the bearing elements are adjustable and fixable with the aid of a volume-resistant composite mass.

DE 39 42 410 A1 shows a machine foundation for supporting machines. Known from this prior art is a height-adjustable bearing element relative to the base of the machine foundation, which can also be fixed in the previously set position with respect to the foundation base with the aid of fixing screws. This prior art, which is only suitable for supporting loads, in this case machine parts, also provides for a casting compound to be introduced into the machine foundation in order to achieve a more uniform load transfer.

In addition, a ship hatch cover is known, in which the filling-side bearing element can be prestressed by means of a spring and adapted to the ship hatch cover. The disadvantage here is that the entire ship hatch cover must be held by an elaborate holding linkage until the filling-side bearing elements are matched in their position to the hatch cover-side bearing elements and are in contact therewith and potting compound is filled and hardened in the space created by the spring.

In the prior art, therefore, a height adjustment of the ship's hatch cover has so far only been provided by means of a bearing on the fill side. If the ship's hatch cover is to be supplied as a part of the supplier, this can lead to coordination problems between the shipyard and hatch cover manufacturer when it comes to adapting the ship's hatch cover to the sill-side warehouse, and thus difficulties in aligning the ship's hatch cover to the sill. In addition, the shipyard has to install and, if necessary, also operate the relatively complicated device for adjusting the height of the storage on the silt side, which often requires increased effort and can lead to further problems, especially if the shipyard lacks the required know-how.

The object of the invention is therefore to improve a ship hatch cover of the type mentioned in such a way that the hatch cover-side bearing element can be adapted to the fill-side bearing element.

This object is achieved in that with a ship hatch cover of the type mentioned, the alignment means have adjustable holding means which Hold the hatch cover-side bearing element on the hatch cover in any position within a certain movement path regardless of gravity.

The advantages achieved by the invention consist in particular in that a height adjustability of the hatch-side bearing element is possible, in every position of the bearing arrangement. According to the invention this is achieved in that the respective bearing element is fixed by the alignment means regardless of gravity. The cooperation of the hatch cover manufacturer with the shipyard producing the silt is simplified considerably because it no longer requires the time-consuming correction of the bearing element on the silt side. Furthermore, with the aid of the invention, greater flexibility in adapting ship hatch covers to the special geometric conditions of the respective ship is achieved.

An advantageous embodiment of the invention is characterized in that the alignment means are accessible from the deck. This ensures simple operation of the alignment means according to the invention. You no longer have to rely on a laborious adjustment of the hatch cover from the hatch, but you can easily adjust the bearing element from the deck. The easy accessibility of the alignment means also makes it possible to carry out the required adjustment work when aligning the ship's hatch cover in relation to the sill in a shorter time than before.

It is particularly expedient to provide at least one access opening in the lateral apron of the hatch cover adjacent to the alignment means. Such an access opening, which is advantageously closable, enables the operating personnel to have convenient access to the alignment means while at the same time maintaining the function of the lateral apron of the ship's hatch cover. In particular in the case of the closable design of the access opening, penetration of water or dirt into the area of the alignment means is prevented.

In a further embodiment of the invention, the ship's hatch cover is characterized in that the alignment means have at least one threaded bolt which is supported on the ship's hatch cover and is in screw engagement with the bearing element and which preferably extends in the direction of movement of the bearing element (with "movement direction" the direction of movement of the bearing element during the adjustment process is designated). A threaded bolt can be a particularly simple, however realize effective height-adjustable adjustment of the bearing element with simultaneous fixation in the set position due to the self-locking effect of the thread. The threaded bolt therefore limits the path of movement of the bearing element during the alignment process and prevents the bearing element from unintentionally detaching from the ship's hatch cover.

An advantageous development of this embodiment is characterized in that it has at least one further threaded bolt which is in screw engagement with the hatch cover and abuts the bearing element on the hatch cover side. With the aid of this threaded bolt, it is possible to align the hatch cover-side bearing element exactly with respect to the ship's hatch cover and thus to carry out an exact adaptation of the hatch cover-side bearing element to the fill-side bearing element.

A further advantageous embodiment of the ship's hatch cover according to the invention, in which the alignment means have lateral guide elements for the bearing element, enables safe lateral guidance of the hatch-side bearing element when aligning the bearing element with respect to the ship's hatch cover. The lateral guide elements can be part of a receptacle for the bearing element arranged on the ship's hatch cover.

In a particularly preferred embodiment, the receptacle is formed by the lower half of an H-shaped profile. Profiles shaped in this way form a sensible closure of the hatch cover towards its edge. They are also very stable and can be used inexpensively as commercially available goods.

In a currently particularly preferred embodiment, an intermediate space between the bearing element and the hatch cover is filled with a casting compound. This known method is simplified considerably with the aid of the invention. Before filling the potting compound into the intermediate space, the hatch-side bearing element can not only be particularly easily and effectively adjusted in height to the opposite bearing partner with the aid of the aligning means according to the invention, but also fixed in the position thus found, so that additional aids are available Holding the ship hatch cover during the adjustment process and during the pouring of the potting compound or on the need to press the potting compound into the space with pressure can be dispensed with.

It is particularly expedient that the space in the lower half of the H-shaped profile is filled with the sealing compound. It is advantageous that the the center line of the H-forming part of the profile has at least one hole for filling the intermediate space with the sealing compound. It is particularly useful that two holes are provided, one for filling and one for venting the space. It is advantageous if the hole for filling is arranged so spaced from the alignment means that the pouring of the sealing compound into the same is not hindered by the alignment means, which are also preferably located on the center line of the H.

The bearing arrangement of the present invention is preferably designed such that at least one of the bearing elements is divided into two parts at an angle, in particular essentially at right angles, to the direction of movement, which are connected to one another by elastic material. This results in greater flexibility of the bearing arrangement with respect to torsion of the hull and thus less wear on the bearing arrangement. One part of the two-part bearing element can have a receptacle for the other part.

Embodiments of the invention are shown in the drawings and are described in more detail as follows.

Ship hatch cover from FIG. 3.

1 shows a longitudinal section through a slide bearing arrangement 1 perpendicular to the surface of a sill bank 10. A sill-side bearing element 4 is attached to a sill bank 10. A ship's hatch cover 2 is supported on the sill-side bearing element 4 with the aid of a hatch-side bearing element 5. The ship hatch cover 2 has on its underside in the region of the plain bearing arrangement 1 a box-shaped receptacle 3, which is delimited by lateral guide walls 3a and an upper wall 3b, partially accommodates the hatch-side bearing element 5 and thereby prevents the hatch-cover-side bearing element 5 resting on the fill-side bearing element 4 from slipping sideways.

Furthermore, one can see in Fig. 1 with the upper wall 3b of the receptacle 3 in the hatch cover 2 in threaded engagement threaded bolts 6, which rest with their lower end on a surface facing the hatch cover 2 5a of the hatch-side bearing element 5. The threaded bolts 6 serve to adjust the height of the hatch-side bearing element 5 in the receptacle 3. Furthermore, a further threaded bolt 7 is provided, which is rotatably mounted in the upper wall 3b of the receptacle 3, is in screw engagement with the hatch-cover-side bearing element 5 and the hatch-cover-side bearing element 5 in the recording 3 and thus on the hatch cover 2 stops. The threaded bolt 7 is designed so that it has a possible inclination of the hatch-side bearing element 5 relative to the hatch cover, which is forced by the threaded bolts 6

2 not significantly restricted.

In the exemplary embodiment shown in FIG. 1, the hatch cover bearing element 5 is horizontally divided in two in a direction substantially perpendicular to its direction of movement during the alignment process and parallel to its bearing surface 5b facing the saddle bearing element 4. For this purpose, the hatch cover-side bearing element 5 comprises a first part 5c which is in contact with the fill-side bearing element 4 and a second part 5e which is held in the receptacle 3 of the ship's hatch cover 2 and which is connected to the first part 5c of the hatch cover-side bearing element 5 via an elastic layer 5d is. The first part 5c of the hatch-side bearing element 5 is located in a box-shaped recess 5f formed in the second part 5e.

1 clearly shows a distance, determined by the threaded bolts 6 and 7, between the surface 5a of the bearing element 5 on the hatch cover side and the upper wall 3b of the receptacle 3 in the hatch cover 2. This spacing results in the box-shaped receptacle 3 in the hatch cover 2 an intermediate space which is filled with a casting compound 8 indicated by dots in FIGS. 1 and 2. The gap is filled with the potting compound 8 via holes 12a and 12b, which are provided in the upper wall 3b of the receptacle 3. One of the holes is used to fill the receptacle 3, while the other hole is used to vent the receptacle 3 serves during filling. The potting compound 8 in the intermediate space fixes the hatch cover-side bearing element 5 in its position aligned with the threaded bolts 6 and 7 relative to the hatch cover 2 and ensures a flat transfer of force between the hatch cover 2 and the sill 10.

The ship's hatch cover 2 is supported on the filler bench 10 with a plurality of slide bearing arrangements, usually all of the slide bearing arrangements used are designed in the manner described above.

The installation of the hatch cover 2 is described below, it being assumed that each slide bearing arrangement 1 is formed in the manner described above. The ship hatch cover 2 is delivered so that the hatch-side bearing element 5 is held loosely in the receptacle 3 by the threaded bolts 6, 7, the threaded bolt 7 preventing the bearing element 5 from falling out of the receptacle 3. The space between the upper wall 3b of the receptacle 3 and the surface 5a of the bearing element 5 is still empty at this time and is not filled with potting compound 8. In this state, the ship's hatch cover 2 is placed on the sill bank 10 in such a way that the hatch cover-side bearing element 5 is aligned with the sill-side bearing element 4 in each plain bearing arrangement 1, as shown in FIGS. 1 and 2.

Then each hatch cover-side bearing element 5 is adjusted in height relative to the sill-side bearing element 4 with the aid of the threaded bolts 6, 7 and thus aligned so that there is a flat contact between the sill-side bearing element 4 and the hatch cover side in all slide bearing arrangements 1. Bearing element 5 comes. After this alignment, the space between the upper wall 3b of the receptacle 3 and the surface 5a of the hatch-side bearing element 5 is then filled with a potting compound 8 through one of the holes 12a, 12b.

In a further embodiment, it is also possible, if the threaded bolts 6, 7 are appropriately dimensioned, to dispense with filling the cavity 3 with the casting compound 8. Furthermore, it is important to emphasize that the number of threaded bolts 6 can be varied as desired, depending on the load requirements placed on the slide bearing arrangement 1.

A further embodiment 2 'of a ship's hatch cover is shown in FIGS. 3 to 5. This ship hatch cover 2 'has a plain bearing arrangement T, which in its construction is the plain bearing arrangement shown in FIGS. 1 and 2 1 is essentially the same. In FIGS. 3 to 5, parts which are essentially the same as those from FIGS. 1 and 2 are therefore designated with the same, but deleted numbers as in FIGS. 1 and 2.

FIG. 3 shows a perspective view of a ship hatch cover 2 '. The ship's hatch cover 2 'essentially consists of an upper flange 20 and a lower flange 22. The horizontally extending upper and lower ribs 20 and 22 are connected to one another by perpendicular webs 24, 26 and 28 which run parallel to one another. The lower flange has circular recesses 22a and 22b. The third web 28 has a semicircular recess 28a. The outer edge 30 of the upper flange 20 and the outer edge 32 of the lower flange 22 are connected to one another by an apron 34.

An H-shaped profile 36 is attached to a partial section of the outer edge 32 on the inside 38 of the lower flange 22 facing the upper flange 20. The H-shaped profile 36 forms a receptacle 3 'with its lower half, which is open towards the inside 38 of the lower flange 22. The receptacle 3 'is bounded towards the upper flange 20 by an upper wall 3b' forming the center line of the H and to the sides by lateral guide walls 3a '.

The top wall 3b 'has a hole 1 2a'. The hole 12a 'connects the upper half of the profile 36 with the receptacle 3' forming the lower half of the H-shaped profile 36.

In the apron 34 which closes the ship hatch cover 2 'towards the deck (see FIG. 4), there is an opening 40 near the hole 12a', adjacent and diagonally above the profile 36. On the one hand, a potting compound (not shown) can be passed through the opening 40 ) into the receptacle 3 'through the hole 1 2a' and on the other hand the aligning means shown in FIG. 4 (see FIG. 4) can be operated through the opening 40.

FIG. 4 shows a section along the line AA of the hatch cover 2 'shown in FIG. 3. The section AA runs along the perpendicular second web 26, which connects the upper flange 20 and the lower flange 22 of the ship's hatch cover 2 'to one another. The second web 26 has a quarter-circular recess 26a in the region of the opening 40. A ratchet 42 is located in the opening 40. The ratchet 42 is seated on a threaded bolt 6 '. The threaded bolt 6 'is in a thread 44 in the upper wall 3b' of the receptacle 3 'in the H-shaped profile 36. The lower end 6 "of the threaded bolt 6' lies on the Surface 5a 'of the upper part 5e' of a hatch-side bearing element 5 '. The upper part 5e 'receives the lower part 5c' of the bearing element 5 'in a recess. The lower part 5c 'lies flat with its underside on a bearing element 4' on the filling side. The sill bench 10 'or the deck of the ship (not shown) is connected to the sill-side bearing element 4'.

The structure of the slide bearing assembly 1 ', i.e. the receptacle 3 ', the bearing elements 4' and 5 'and their function in interaction with the threaded bolt 6' corresponds to the structure of the plain bearing arrangement 1 described in FIGS. 1 and 2.

In contrast to the plain bearing arrangement 1, a seal 46 sealing the ship's hatch cover 2 'with respect to the deck 10' is provided in the plain bearing arrangement 1 '. The seal 46 is fastened in a box-shaped recess adjacent to the slide bearing arrangement 1 ', which is defined by the skirt 34, the edge section 22c of the lower flange 22 running perpendicular thereto and the lateral guide wall 3a' running perpendicularly to it on the side of the H- facing the skirt 34. shaped profile 36 is formed. The seal 46 protrudes from this recess. The front edge 46a of the seal 46 comes into contact with the bench 10 '.

The H-shaped profile 36 is located in a recess in the lower flange 22. The recess or the profile 36 located therein divide the lower flange 22 into an edge section 22c and a remaining part. Both the profile 36 and the apron 34 are connected to the lower flange by welds 48.

The cavity formed by the upper flange 20, the apron 34, the edge portion 22c of the lower flange 22 and by the upper part of the H-shaped profile 36 in the ship hatch cover 2 'becomes towards the inside of the ship hatch cover 2' by a perpendicular to the second web 26 extending fourth web 50 limited. 5, the cavity is delimited by the first web 24 and the third web 28. The web 50 is seated on the side of the H-shaped profile facing the interior of the ship's hatch cover 2 ′ and is also connected to the upper flange 20 by welds 48.

The section shown in FIG. 5 along line BB in FIG. 3 again illustrates the structure of the ship hatch cover 2 ′ shown in FIGS. 3 and 4. The section BB runs along the third web 28. If the ship hatch cover 2 'is now to be aligned with respect to the sill bench 10', the procedure described in relation to the slide bearing arrangement 1 of FIGS. 1 and 2 is followed. The ratchet 42 is placed through the opening 40 on the threaded bolt 6 'in the thread 44. The threaded bolt 6 'aligns the bearing element 5' with respect to the bearing element 4 'on the filling side in accordance with the procedure described for the plain bearing arrangement 1. A potting compound (not shown) is then filled into the receptacle 3 'through the opening 40 through the hole 12a'. During the filling of the receptacle 3 ', the air in the receptacle 3' can escape through a second hole 12b 'shown in FIG. 5 in the upper wall 3b' of the receptacle 3 '.

Then, if necessary, the holes 1 2a ', 12b' and the opening 40 can be closed after the ratchet 42 has been pulled off the threaded bolt 6 'and removed from the opening 40. The holes 12a ', 12b' and the opening 40 are usually closed with the aid of plastic lids (not shown).

It should also be mentioned that not only the hatch cover-side bearing element 5, 5 'is divided into two and can be aligned and held against the hatch cover 2, 2' with the aid of aligning means, but that instead, or in addition, the filler-side bearing element 4, 4 'can be carried out in the same way.
