Abstract

The utility model discloses a deck cable guide, which is an integrated structure of cast steel; a cable opening is arranged at the central part of cable guide for the anchor chain or cable to pass through, a front piece and a rear piece of the same size are respectively arranged at the front and rear end of cable guide. The shape of the opening of cable guide is a rectangular which is approximately elliptical shape with fillet on the two ends, the horizontal opening size is 600 mm, the vertical opening size is 450 mm, the geometry surface profile of the opening is the symmetric structure and the opening surface is smooth and sleek to prevent cable and anchor chain from wearing when contacting with the surface. Horizontal, vertical, and diagonal stiffeners are arranged on the cable guide to increase the stiffness and strength of the cable guide. The utility model has the advantages of compact structure, reasonable opening, attractive appearance and practical usage; besides ordinary ships for towing or mooring, the utility model is also suitable to navigate ships in the Panama Canal waterway for towing or mooring.

Description

Deck formula fairlead

Technical field

The utility model relates to and is used for boats and ships support hawser or anchor chain device, more specifically refers to a kind of deck formula fairlead, utilizes this fairlead to realize the towing or the mooring of boats and ships.

Background technology

The structure that tradition is used for the deck formula fairlead 10 of the towing of boats and ships or mooring sees also Fig. 1, Fig. 2, it is the integrative-structure solid of being cast by cast steel, the centre leave be used to place hawser lead cable perforate 11, front and back are respectively equipped with anter 12, rear panel 13, anter 12 varies in size with rear panel 13, small one and large one.Though this fairlead prolongs towing or the mooring that is used for boats and ships always.But also there is following shortcoming: 1, middle perforate 11 is too small, and its upperlimit is no more than 500mm * 260mm; 2, the power that supports hawser or anchor chain is too small, can not bear large tonnage boats and ships towing or mooring; 3, can't satisfy and develop shipping demand rapidly.

Summary of the invention

The purpose of this utility model is the above-mentioned shortcoming that exists at traditional fairlead, and a kind of deck formula fairlead is provided.

For achieving the above object, the utility model has adopted following technical scheme:

This deck formula fairlead is the integral structure that cast steel is cast, and the body middle part of fairlead offers mooring pipe, and the front and back end of fairlead is respectively equipped with anter, rear panel,

Described fairlead anter is identical with the rear panel size;

The described oblong that is shaped as the double headed roller fillet of leading the cable perforate, horizontal opening is of a size of 600mm, and vertical opening size is 450mm.

Described fairlead be respectively equipped with level to, vertically to, oblique reinforced rib.

Described lead the cable perforate be shaped as the sub-elliptical shape.

In technique scheme of the present utility model, this fairlead is the integral structure that cast steel is cast, the body of fairlead middle part offer be used to place hawser or anchor chain lead the cable perforate, the front and back end of fairlead is respectively equipped with size identical anter, rear panel.Lead the oblong of the double headed roller fillet that is shaped as the sub-elliptical shape of cable perforate, horizontal opening is of a size of 600mm, vertical opening size is 450mm, and the morphology section in hole is a symmetrical structure, and the surface smoothing slyness in hole is with prevent that hawser or anchor chain from contacting with this face time wearing and tearing.Fairlead be respectively equipped with level to, vertically to, the oblique 40 ° reinforced rib in below, to increase the rigidity and the intensity of fairlead.The utility model compact conformation, opening are reasonable, both artistic and practical.Except being used for common ship towing or mooring, also being suitable for to navigate by water and being pulled or mooring in the boats and ships in Panama Canal navigation channel.

Description of drawings

Fig. 1, Fig. 2 are respectively that traditional fairlead is faced, the plan structure scheme drawing.

Fig. 3, Fig. 4 are respectively that deck of the present utility model formula fairlead is faced, the plan structure scheme drawing.

The specific embodiment

In order to understand technique scheme of the present utility model better, describe in detail further below in conjunction with drawings and Examples.

See also Fig. 3, shown in Figure 4, the integral structure that deck of the present utility model formula fairlead 30 is cast for cast steel, the body of fairlead middle part offer be used to place hawser or anchor chain lead cable perforate 31, the front and back end of fairlead 30 is respectively equipped with size identical anter 32, rear panel 33.Its horizontal opening is of a size of 600mm, vertical opening size is 450mm, leads the oblong of the double headed roller fillet that is shaped as the sub-elliptical shape of cable perforate 31, and horizontal opening is of a size of 600mm, vertical opening size is 450mm, and the morphology section in its hole is a symmetrical structure.This deck formula fairlead level and vertical direction and downwards the oblique angle locate (becoming 40 °) for 40 ° and be respectively equipped with reinforced rib 35,36,37 with the angle of horizontal stiffener, promptly, the fairlead body be provided with vertical reinforced rib 35, horizontal stiffener 36, and oblique reinforced rib 37.

When being used for boats and ships towings or mooring, this fairlead 30 is fixed on the deck, is used for pulling or the hawser or the anchor chain of mooring pass by leading cable perforate 31, can carry out artificial or power operation easily.Because it is bigger to lead cable perforate 31 openings, so even hawser or anchor chain more also can pass, and hole surface fairing slyness can obviously reduce the hawser that passes through or the wearing and tearing of anchor chain.Owing to the effect of reinforced rib, the rigidity and the intensity of fairlead are obviously strengthened simultaneously, and the bearing force safe working strength that can provide is 2000kN, and ultimate strength is 4000kN.

By foregoing description as seen, deck of the present utility model formula fairlead has comformability and working strength preferably, the front and back sheet size of this fairlead is identical, opening size is big and be provided with reinforced rib, actv. has solved problems such as original fairlead bad adaptability, working strength be low, can provide safeguard for the shipping industry that develops rapidly.

Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
