Description
Technical Field
The utility model relates to a marine vessel fitting-out technical field, in particular to marine vessel bulwark strengthening rib fairlead hole.
Background
The cable guide hole is also called a bulwark cable hole, is a closed hole-shaped cable guide device which is arranged on a bulwark and used for limiting the cable guide position, and is a circular or elliptical annular casting. The fairlead is usually made of cast iron or cast steel, is installed on the side wall, guides the cable through the hull, and prevents the cable from damaging the hull.
The fairlead is the essential fairlead device of boats and ships in-process of stopping a journey, and the fairlead hole generally inlays on the bulwark, and when the hawser was through the fairlead hole, the contact surface was arc to avoid the bulwark to the cutting effect of hawser, also be convenient for the smooth head of the hawser to pass through. Due to various requirements of ships, such as berthing at a wharf and berthing between ships, cables are connected through cable guide holes, and if various factors exist, such as wind waves, tides and the like, the cables can move to a certain extent under the action of huge force. In the process of ship oscillation, the cable generates reciprocating friction force on the cable guide hole, the friction force of the cable guide hole is mainly concentrated on two sides of the lower part of the cable guide hole, and the cable guide hole is prone to deformation caused by uneven stress along with long-time reciprocating friction of the cable, so that the service performance of the cable guide hole is affected, and the service life of the cable guide hole is shortened.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome and rock the in-process at boats and ships, the hawser produces reciprocal frictional force to the fairlead, the frictional force in fairlead hole mainly concentrates on fairlead hole lower part both sides, along with the long-time reciprocal friction of hawser, leads to the irregular production of fairlead atress to warp easily, influences the performance in fairlead hole, reduces the problem that this one of life of fairlead hole is urgent to wait to solve, provides the marine boats and ships bulwark strengthening rib fairlead hole in order to solve above-mentioned problem.
The utility model provides a marine vessel bulwark strengthening rib fairlead hole, its characterized in that: the cable guide hole seat comprises an oval cable guide hole, a cable guide hole seat body and reinforcing ribs, wherein the reinforcing ribs are arranged at the top of the cable guide hole seat body, the reinforcing ribs are respectively arranged at the left side and the right side of the cable guide hole seat body, two reinforcing ribs are arranged at the lower part of the cable guide hole seat body, and an included angle between the two reinforcing ribs at the lower part is 60-65 degrees.
Further, the surface roughness of the oval cable guide hole is Ra0.8mm.
Further, the oval cable guide hole can pass through a cable with the diameter of 250 mm.
Further, the thickness of the reinforcing rib is 38 mm.
Compared with the prior art, the utility model has the advantages that: be equipped with two strengthening ribs through fairlead hole pedestal lower part, the contained angle between the strengthening rib of lower part two is 60 to 65, strengthen the support intensity of fairlead hole lower part, avoid the uneven production of fairlead hole atress to warp, be Ra0.8mm through oval fairlead hole surface roughness, reduce the frictional force between hawser and fairlead hole, can avoid the bulwark to the cutting action of mooring line, the smooth passage of the mooring line lute head of also being convenient for, improve the performance in fairlead hole, increase the life in fairlead hole.
