Definitions
- 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.
- 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.
- 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.
- a ship hatch cover 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- the hatch-side bearing element 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.
- the space in the lower half of the H-shaped profile is filled with the sealing compound.
- 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.

- 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
- 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.
- 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.
- FIGS. 1 and 2 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.
