Description
Technical field
The present invention relates to over-water construction mooring arrangement technical field, and in particular to a kind of traversing mooring fairlead of immersed tube.
Background technology
Mooring arrangement is the part for belonging to ship equipment, suitable for aquatic work and offshore construction environment, using offshore vessel
It is than better suited selection that oceangoing ship equipment standard, which designs and produces the traversing mooring stranded cable system equipment of immersed tube,.Chock be hawser be oriented to and
Protection hawser normally draws the necessary equipment of work.Matching of the chock with stranded cable system and the applicability to environment, its quality
Directly affect the whole construction operation of ship or the construction operation of whole scene.Chock used by existing construction ship
Be mostly fixed gate seat multi-roller chock, or goat's horn list fairlead with horizontal roller, or hold-down support can bidirectional rotation pulley
Chock.
The immersed tube prefabricated dock chamber environment of an activation of certain seabed tunnel is complicated, and immersed tube is traversing to be needed to fill drop above and below draining into dock chamber
15.3m, its activity space change greatly, and scope of activities area is big, it is desirable to the hawser of mooring stranded cable system energy is multi-faceted, wide-angle,
The guiding conversion of long range, including more than 180 ° guidance tape cables, traversing immersed tube, mooring can be met in dock chamber, undocked and dock gate
The Operations Requirements of opening and closing, while the mooring checking bollard of the Operations Requirements arrangement in dock chamber is more, it is more to lead cable point position, causes mooring to lead cable system
Unite huge.
It leads that cable angle is small, and direction is restricted for existing multi-roller chock or single fairlead with horizontal roller, and it is low to lead cable efficiency,
Easily injure hawser and chock in itself.Hold-down support can bidirectional rotation rolling chock, although adding guide angle, change
Guide direction has been apt to it, has improved and lead cable efficiency, but guide angle and direction also suffers from limitation, can not meet big more than 180 °
Angle, multi-party guide cable spatially need.
The content of the invention
Present invention aims at：It is small because leading cable angle for existing chock, and lead cable direction to be restricted and can not
A kind of the problem of satisfaction leads the wide-angle that cable angle is more than 180 °, and multi-party guide cable spatially needs, there is provided traversing system of immersed tube
Fairlead is moored, the fairlead, which disclosure satisfy that, leads the guiding that cable angle is more than 180 °, and multi-party guide cable need spatially
Will, it can effectively reduce and change cable number, improve efficiency of construction.
To achieve these goals, the technical solution adopted by the present invention is：
A kind of traversing mooring fairlead of immersed tube, including checking bollard, chock and slide bushing assembly are led, the slide bushing assembly set
Be located at and lead on checking bollard and can rotate about, the chock be arranged on slide bushing assembly on, be also hinged with the slide bushing assembly to
Few a set of open type coaster.
The present invention leads checking bollard by setting and rotatable slide bushing assembly is set on checking bollard is led, while in slide bushing assembly
Upper setting chock and open type coaster, the chock and open type coaster can rotate together with slide bushing assembly around 360 ° of checking bollard is led so that
One stake potential energy meets that two hawsers go out more than 180 ° guiding of cable simultaneously, universal can spatially lead cable, at the same this lead checking bollard can be with
Used as bollard so that the device disclosure satisfy that mooring and to lead cable dual-purpose, can greatly simplify mooring and lead cable system, reduce
Basis instrument.
As the preferred scheme of the present invention, the slide bushing assembly includes upper sliding sleeve and low sleeve, the upper sliding sleeve, low sleeve
Between be provided with and be fixed on the circular orientation plate led on checking bollard.By setting upper sliding sleeve and low sleeve can be in order to chock and open type
Coaster is connected, and both both can be each around checking bollard rotation be led, again can be convenient to adjust guide direction, while the ring with unitary rotation
Shape location-plate can avoid upper sliding sleeve and low sleeve edge from leading checking bollard and slide up and down.
As the preferred scheme of the present invention, the low sleeve is formed by connecting by two semicircle sets, can be in order to low sleeve
The operation such as installation and subsequent maintenance and replacing.
As the preferred scheme of the present invention, the chock includes gate seat, is vertically provided with the gate seat at least one vertical
Roller, two transverse idlers are also correspondingly provided with the gate seat.By setting gate seat, vertical roller and transverse idler, then coordinate sliding sleeve
Component is used together, it is possible to achieve 360 ° of hawser guiding, when the drag of traction is from the side yaw of checking bollard is led to leading checking bollard
During opposite side, its pull-cord needs, across the top for leading checking bollard, to be laterally moved to opposite side from the side for leading checking bollard, now use
The chock do not have to change cable can a sub-band cable complete traction task, that is, realize around stake draw.
As the preferred scheme of the present invention, the vertical roller is two, and the open type coaster is a set of, can give two simultaneously
The hawser of platform winch is oriented to.
As the preferred scheme of the present invention, it is described lead that checking bollard includes being connected with each other lead and checking bollard cylinder and lead checking bollard base,
Described to lead checking bollard cylinder top installation slide bushing assembly, the checking bollard base of leading is connected on ground.
As the preferred scheme of the present invention, the checking bollard cylinder bottom of leading is provided with for more hawsers to be layered into the rings with cable
Shape dividing plate, more hawser layering band cable moorings can be met, cable is conveniently changed and untie the mooring rope.
As the preferred scheme of the present invention, it is described lead be additionally provided with the top of checking bollard cylinder it is vexed for preventing from altering on slide bushing assembly
Lid.
In summary, by adopting the above-described technical solution, the beneficial effects of the invention are as follows：
1st, the present invention leads checking bollard by setting and rotatable slide bushing assembly is set on checking bollard is led, while in sliding sleeve group
Chock and open type coaster, the chock and open type coaster is set to make together with slide bushing assembly around 360 ° of rotations of checking bollard are led on part
Stake potential energy meets that two hawsers go out more than 180 ° guiding of cable simultaneously, universal can spatially lead cable, at the same this lead checking bollard can
To be used as bollard so that the device disclosure satisfy that mooring and to lead cable dual-purpose, can greatly simplify mooring and lead cable system, subtract
Basis instrument is lacked；
2nd, by set slide bushing assembly and open type coaster and both can around lead checking bollard rotate, open type coaster guide cable friction
Minimum, efficiency highest, steel wire rope is protected optimal, and hawser steric direction scope is big, and planar guide angle is big, has accomplished to be more than
180 ° of guiding, meet the wide-angle political reform of the traversing cable of immersed tube in place and do not change cable, operating efficiency is high；
3rd, by setting chock at the top of checking bollard it can realize 360 ° of hawser guiding leading, when the drag of traction is from stake
Side yaw to stake opposite side when, its pull-cord needs the top across checking bollard, and opposite side is laterally moved to from the side of stake
Go, now using the chock do not have to change cable can a sub-band cable complete traction task, that is, realize around stake draw.
