Abstract
The invention discloses a kind of underwater fairlead for anchor chain mooring, including upper bracket, lead cable holder, chain cable fairlead, main shaft and countershaft, undersetting.It is respectively cased with a sliding bearing between bearing and main shaft above and below, sliding bearing is also cased between chain cable fairlead and countershaft.Chain cable fairlead is supported on by countershaft leads on cable holder, leads cable holder by main shaft support on upper and lower bearing.Upper and lower bearing is respectively equipped with fixed baffle, realizes the fixation of fairlead on the body construction.Anchor chain realizes anchor chain guide function by leading cable wheel.The present invention can improve anchor chain guidance capability, and it can be ± 90 ° around spindle swing, angle to lead cable holder together with chain cable fairlead (3), can be worked normally between anchor chain and 0 °~90 ° of the departure angle (angle with horizontal plane α) of chain cable fairlead.Bearing uses water lubrication simultaneously, and uses resistant material with axis, overcomes the underwater fairlead of anchor chain under water easily by the problem of seawater corrosion, improves the service life of fairlead and reduce maintenance cost.
Description
Technical field
The present invention relates to a kind of anchor chain fairlead, especially it is a kind of can multi-angle lead cable, and effectively prevent anchor chain card resistance,
The underwater anchor chain fairlead that corrosion-resistant, antirust, service life are long, maintenance cost is low.
Background technology
Currently, the anchor chain fairlead of windlass equipment in the market is usually all mounted on deck, seldom it is submerged by water,
But the anchor chain fairlead on deck is not suitable for the positioning system of ocean platform mooring, if it is easy to work under water for a long time
It is corroded, gets rusty.
Invention content
Goal of the invention：A kind of energy multi-angle of present invention offer leads cable, and effectively prevent anchor chain card resistance, corrosion-resistant, antirust, makes
With the low underwater anchor chain fairlead of long lifespan, maintenance cost.
Technical solution：In order to solve the above technical problems, a kind of underwater fairlead for anchor chain mooring of the present invention, packet
It includes upper bracket, lead cable holder, chain cable fairlead, main shaft, undersetting, anchor chain, upper bracket is mounted on above main shaft, and undersetting is mounted on master
Below axis；It is cased between upper bracket and main shaft between the first sliding bearing, undersetting and axis and is cased with the second sliding bearing, lead cable branch
Frame is mounted on main shaft and extends to the side of main shaft；
It leads and is horizontally installed with countershaft on cable holder, chain cable fairlead is mounted on the countershaft and is rotated around countershaft；Chain cable fairlead with
Third sliding bearing is cased between countershaft；It is additionally provided with the first fixed baffle on upper bracket, is additionally provided with the second fixation gear on undersetting
Plate；It leads cable wheel carrying anchor chain and drives the folding and unfolding of anchor chain by leading the rotation of cable wheel.
Further, it is ± 90 ° to lead cable holder and drive lower swing, angle in the rotation of main shaft together with chain cable fairlead.
Further, anchor chain, which is led, is provided at least five groove among cable wheel.
Further, 0 °~90 ° of the departure angle position of anchor chain and chain cable fairlead.
Further, the first sliding bearing, the second sliding bearing, third sliding bearing are all made of the sliding axle of water lubrication
It holds, material for sliding bearing uses corrosion resistant engineering plastic alloy material.
Advantageous effect：A kind of underwater fairlead of anchor chain mooring of the present invention, overcomes the anchor chain of deck windlass equipment
Corrosion-resistant, antirust the technical barrier of fairlead key structure realizes and carries out the function that multi-angle anchor chain leads cable under water,
Anchor chain can be passed through.The fairlead may be mounted in the exterior side wall of platform structure, be propped up above and below by fairlead
First, second baffle of seat is welded on platform structure.The place normal work that fairlead can not observe under water, it is real
While existing anchor chain mooring underwater leads cable and lead the drive folding and unfolding of cable wheel, the rotation that can also pass through main shaft changes the folding and unfolding that lead cable
Direction.To：
1. ensureing that anchor chain passes through guide wheel under the effect of 12000KN nominal load, prevents anchor chain to be disengaged from the groove, have no anchor chain card
Hinder phenomenon.
2. in order to ensure that corrosion-resistant, the antirust of underwater fairlead, sliding bearing use water lubrication, and material selection engineering
Plastic alloy.
