Abstract

A cable towing and guiding device includes a cable towing stop piece (4), and cable seat (2) that amplexiforms with block and the towing cable (1) that is fixed on the cable seat are formed.Greater than the diameter of towing cable (1), purpose is shifted laterally and the wearing and tearing that prevent towing cable to fairlead mooring hawse bore slightly.Tubaeform member adjacency in mooring hawse (12) and the fairlead.It is an integral rigidity member that this tubaeform member is welded by the plate with single curvature (7,7 ', 8,10).This simple structure provides bigger bending curvature to towing cable.

Description

Hawse hole, fairlead or hill holder

When the towing ship (particularly on the ocean), often use cable wire.If allow cable wire draw dragging device to link to each other by the closed fairlead of a Panamanian type and with one with common method.Like this, cable wire since its shifted laterally in the fairlead mooring hawse will be easy to be worn, therefore, when cable wire when being pulled thing and being connected, normally cable wire is linked to each other with a chain by fairlead, this chain then is connected on the special brackets of the inboard a certain position of fairlead.

The present invention relates to combination hawse hole, fairlead or a hill holder and a block, its volume is little and cable is linked to each other with block itself.This fairlead both had been applicable to that cable wire also was applicable to textile rope.This fairlead has reduced the shifted laterally of cable, thereby has also reduced the wearing and tearing of cable.This compact design makes and obtain bigger bending spring under the situation that does not increase the fairlead oad.

Cable is attached on the direct sleeve by the fairlead support.The mooring hawse aperture of fairlead greater than the diameter of cable, could link to each other with sleeve thereby make cable must pass through fairlead slightly.Because the fairlead opening is done narrower and smallly, so can ignore the shifted laterally of cable in this part of fairlead.Secondly, cable will be through a horn-like part that allows to produce 90 ° of bendings along all directions.This part can be formed by the some blocks of plates (that is, they have single curvature) along a direction bending.

In order to understand the present invention better, the embodiment sample of describing in is below with reference to accompanying drawings done an explanation: here

Fig. 1 represents the vertical longitudinal profile view according to fairlead first embodiment of the present invention.

Fig. 2 represents the frontal view of fairlead shown in Figure 1.

Fig. 3 represents the vertical longitudinal profile view according to fairlead second embodiment of the present invention.

Fig. 4 represents the frontal view of fairlead shown in Figure 3.

Fig. 5 represents the horizontal longitudinal profile view according to the 3rd embodiment of fairlead of the present invention.

Fig. 6 represents the lateral plan of fairlead shown in Figure 5.

Fig. 7 represents the vertical longitudinal profile view of fairlead shown in Figure 5.

Fig. 8 represents the horizontal longitudinal profile view according to the 4th embodiment of fairlead of the present invention.

In each width of cloth figure, close each other part is with identical label.

In Fig. 1, the part (5) that goes up on the fairlead with its column part adjacency of cable (1) the column part 4 adjacent cable seats (2) that are fixed on one and fairlead (3) is horn-like as can be seen.These parts of fairlead all link to each other with baseplate (6), and as can be seen from Figure 2, horn-like part has a central through hole (11), and its aperture is slightly greater than the diameter of cable (1).The fairlead of making according to Fig. 1, Fig. 2 allows cable to produce 90 ° of bendings along all directions.

In many practical applications, 90 ° of bendings of cable only need fairlead to provide in the horizontal direction, and the bending of vertical direction is actually usually and is significantly smaller than 90 °.The fairlead that is used for this situation as shown in Figure 3, Figure 4.In order to simplify the manufacturing of fairlead, adopt plate welded structure completely, the some of them plate is flat, the other plate only has mono-curvature.Therefore, 90 ° of bendings that just produced level along side plate (7,7 '), and side plate (7,7 ') is welded on the base plate (8), crooked about 45 ° of base plate (8).This fairlead also has a top board (10) that sinuousness is all littler than above-mentioned plate.A header board (9) that is welded between top board (10) and the biside plate (7,7 ').Substrate (6) is welded on base plate (8) and the biside plate (7,7 ').This fairlead can also have increases the brace panel of impregnability (not shown).In this embodiment, mooring hawse (12) has a quadrangular section, but its bore is still very little, is enough to prevent the shifted laterally and the wearing and tearing of cable.

Embodiment shown in Fig. 5-7 has garden post part (4) and by each piece plate (that is, substrate 6, base plate 8, side plate 7,7 ' and the tubaeform part of top board (4) formation.In addition, this fairlead is connected on the stern as shown in the figure.

In this embodiment, thrust part (4) has an open or flaring part (5), and this exit skirt extends to ring cross-section 13 always.The

plate

7,7 of formation fairlead sponson '.8 with thrust part 4 in abutting connection with and tangent with annulus part (13).In this embodiment, the innermost part of above-mentioned each piece plate is straight as shown in the figure, still, should be interpreted as them the continuity of tubaeform part (5) curved surface.This embodiment has also represented one from the abut surface of cylinder part (4) outward extending pipe (16).This pipe (16) can be provided with and be used for storing the cable (1) when not using along the boat deck, take proper device to pull back by pipe connecting block (2).

In actual applications, must reasonably settle pipe (16) so that it does not take working space on the boat deck.Thereby, with railing or the gunnel setting of pipe (16) along ship.Normally intersect with a non-angle of 90 ° and stern 15.An example has like this showed in Fig. 8, and its structure of the fairlead here still can make cable (1) along stern (15) bending, this just mean cable on horizontal surface sidewise bending greater than 90 °.

Claims
