Problems solved by technology

However, with the increase of the tonnage of modern ships, the current ship docks seem very short. At this time, when the ship is moored, the mooring ropes are easy to rub against the side shell, which is not conducive to mooring; The service life of the rope increases the operating cost and also brings safety hazards to the ship
However, due to some other factors such as the construction cost of the ship wharf, it is not suitable for rebuilding the wharf
Therefore, mooring with the traditional fairlead roller device can no longer meet the development and needs of modern shipping.

Embodiment Construction

[0009] The present invention comprises a fairlead roller seat 2 and a fairlead roller 1 vertically arranged thereon, the fairlead roller seat 1 is arranged on the forecastle deck 3, and the fairlead roller seat 2 extends outward from the side outer plate 4, The outer part is supported by a semicircular steel set on the side outer plate 4, the fairlead roller seat 2 is inclined downward along the mooring direction of the ship, and the contact part between the fairlead roller seat 2 and the fairlead rope adopts an arc-shaped structure.

[0010] In the present invention, a fairlead roller seat 2 is inclined at a certain angle, so that the fairlead roller 1 and the cable have the same angle when the cable is carried, reducing the stress on the fairlead roller seat 2; Its base of the part of 4 strengthens especially with semicircular steel, makes hawser and can't run into side outer plate 4; The 3rd, stretch out the fairlead roller seat 2 of side outer plate 4 all around and be weld...

Abstract

The invention relates to a fairlead device for ships. The invention relates to the fairlead device, which comprises a fairlead base and a fairlead arranged vertically thereon, wherein the fairlead base is arranged on a forecastle deck and a poop deck and extends outwards from a topside outside plate; the outer side part of the fairlead base is supported by a half-round bar arranged on the topside outside plate; the fairlead base tilts downwards along the mooring direction of the ships; and a contact part of the fairlead base and a guide rope adopts a circular arc structure. The fairlead device has the advantages that only the frictional loss of the rope can be avoided and the ship operation cost can be reduced, but also the fairlead device is more advantageous for ship mooring and increasing the security of the ship mooring. The fairlead device is refitted from the prior fairlead device so that the reconstruction cost is low.

Description

technical field [0001] The invention relates to a cable roller device, in particular to a cable roller device for ships. Background technique [0002] At present, the known fairlead roller is that the fairlead roller seat is vertically installed on the bow and stern deck near the side. When mooring, the cable first passes through the fairlead roller, and then is fixed on the bollard or the winch. However, with the increase of the tonnage of modern ships, the current ship docks seem very short. At this time, when the ship is moored, the mooring ropes are easy to rub against the side shell, which is not conducive to mooring; The service life of the rope increases the operating cost and also brings safety hazards to the ship. And because of some other factors such as the construction cost of the ship wharf, it is not suitable for rebuilding the wharf. Therefore mooring with the traditional fairlead roller device can no longer meet the development and needs of modern shipping....
