Abstract
The present invention relates to a towline fairlead which comprises a towline stop block (4), a line seat (2) stuck on the stop block, and a towline (1) fixed on the line seat. In order to prevent the lateral movement and the abrasion of the towline, the aperture of the fairlead hole of the fairlead is slightly larger than the diameter of the towline (1). The fairlead hole (12) is connected with a flared component in the fairlead in an adjacent mode, and the flared component is formed by that the method that plates (7, 7', 8, 10) with single curvature are welded into an integral rigid component. The simple structure provides large bending curvature for the towline.
Description
Be used to pull the cable towing and guiding device of ship when the present invention relates to ship's navigation.
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, so, cable wire will be easy to be worn owing to its shifted laterally in the fairlead mooring hawse.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 objective of the invention is to overcome above-mentioned shortcoming provides a kind of cable towing and guiding device, and its volume is little and towing cable is linked to each other with cable seat 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 towing cable, thereby also reduces the wearing and tearing in towing cable.This compact design makes and obtain bigger bending spring variation range under the situation that does not increase the fairlead oad.
The present invention is achieved in that in the mooring hawse of fairlead outside horn-like parts is set, thereby its bending spring has bigger variation range when making towing cable crooked.These horn-like parts can be symmetrical in mooring hawse desired shape or cross-section plate by one and constitute, and also can be made up of two above single panels.
Towing cable is attached on the direct cable seat by the fairlead support.The mooring hawse aperture of fairlead greater than the diameter of towing cable, could link to each other with the cable seat thereby make towing cable must pass through fairlead slightly.Because the fairlead opening is done narrower and smallly, so can ignore the shifted laterally of towing cable in this part of fairlead.Secondly, towing cable will be through horn-like parts that allow to produce 90 ° of bendings along all directions.These parts can be formed by the some blocks of plates (being that they have a single curved surface) 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, similar each other part is denoted by the same reference numerals.
In Fig. 1, towing cable (1) is fixed on the adjacent cable seat (2) of the cable towing stop piece (4) of and fairlead (3) as can be seen.Part (5) with the cable towing stop piece adjacency on the fairlead is horn-like.These parts of fairlead all link to each other with substrate (6), and as can be seen from Figure 2, horn-like part has mooring hawse (11), and its aperture is slightly greater than the diameter of cable (1).The fairlead of making according to Fig. 1, Fig. 2 allows towing cable to produce 90 ° of bendings along all directions.
In many practical applications, 90 ° of bendings of towing 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 is only in the single direction bending.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 towing cable.
The tubaeform member that embodiment shown in Fig. 5-7 has cable towing stop piece (4) and is made of each piece plate (being substrate (6), base plate (8), side plate (7,7 ') and top board (14)).In addition, this fairlead is contained on the stern as shown in the figure.
In this embodiment, cable towing stop piece (4) has an open or flaring part (5), and this exit skirt extends to ring cross-section (13) always.The plate (7,7 ', 8) that constitutes the fairlead sponson and cable towing stop piece (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 an outward extending pipe of cable seating face (16) from cable towing stop piece (4).This pipe (16) can be provided with and be used for storing the towing cable (1) when not using along the boat deck, take proper device to pull back cable seat (2) by pipe.
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 towing cable (1) along stern (15) bending, this just mean towing cable on horizontal surface sidewise bending greater than 90 °.
