Description
Technical field
The present invention relates to a kind of portable heavy-duty hoisting rope-winding method, belong to Naval Architecture and Ocean Engineering field.
Background technology
Crane on ship generally welds hanger, by steel during heavy-duty hoisting experiment is carried out on lifted weight thing
Cord docks a pair of shackles and connects single hanger, completes lifting and displacement.During with the method lifting operation, when hanger crosses 4 more
When individual, weight is easily tilted, steel wire rope is broken because of unbalance stress, abrasion, it is necessary to constantly adjust between steel wire rope and hanger
Angle；And during shackle installation fee；The length of steel wire rope is difficult to control.For heavy-duty hoisting, because the power that steel wire rope is born is limited,
So as to cause wirerope diameter limited, it is necessary to set hanger more, so as to increase shackle, cause because shackle can not be arranged in suspension hook too much
On.
The content of the invention
The technical problems to be solved by the invention are：For the hoisting test method lifting operation mistake referred in background technology
The technical problem run into journey.
The design philosophy of the present invention is to provide a kind of heavy-duty hoisting rope-winding method, makes steel wire rope uniform force, reduces steel wire
The abrasion of rope, lifted weight thing be steady, it is easy to operate, reduce steel wire rope quantity, reduce cost, improve the features such as security.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of portable heavy-duty hoisting rope-winding method, comprises the following steps：
Step 1, preparation, a lifting-steel-rope and the suspension centre steel pipe no less than one；Suspension centre steel pipe is located at barge master
Below deck and suspension centre steel pipe is arranged side by side successively from bow to stern；
Step 2, one end of lifting-steel-rope are fixed on crane hook；
The other end of step 3, lifting-steel-rope, first passes around suspension centre steel pipe, and next is wrapped on suspension hook, passes around again next
Individual suspension centre steel pipe；
Method in step 4, circulation step 3, all suspension centre steel pipes are bypassed successively from bow to stern；
Step 5, after treating that step 4 is completed, the end of lifting-steel-rope is fixed on crane hook.
Suspension centre structure in the inventive method replaces conventional otic placode using steel pipe, and suspension centre structure is by multiple steel pipes
Into, steel wire rope only with one, and steel wire rope to bow, stern from radially distributing in ship.The quantity of lifting-steel-rope is one
Root, a lifting-steel-rope bypass at least one suspension centre steel pipe.In technical solution of the present invention, shared one of multiple suspension centre steel pipes rise
Cable wire is hung, cable wire slings weight, avoids caused by more cable wires：Some cable wires do not have stress, some cable wires during lift heavy
Then there is no the problems such as sufficient space arranges cable wire beyond its safe working load, suspension hook.
Improvement to the inventive method, suspension centre steel pipe are integrally formed with barge agent structure.Preferably by suspension centre structure institute
The power being subject to is to full ship transmission；Single cable wire passes around multiple suspension centre structures, cable wire uniform load transmission suffered by guarantee.
Improvement to the inventive method, lifting-steel-rope to bow and stern from radially distributing in ship.
Improvement to the inventive method, the lifting-steel-rope in step 1 is steel wire rope.
Improvement to the inventive method, suspension centre steel pipe is interior to set reinforcement, and reinforcement is set along suspension centre length of steel pipe direction.
The diameter of steel tube of suspension centre steel pipe is more than 5 times of lifting-steel-rope diameter, while steel duct does reinforcement, both ensure that suspension centre intensity
Steel material weight is alleviated again, is reduced the minimum friction between cable wire and suspension centre structure, is improved the safety coefficient of cable wire and use the longevity
Life；It is easy to cable wire to pass around the cost-effective and time again simultaneously.
Improvement to the inventive method, the non-slip hook for preventing lifting-steel-rope from departing from is provided with suspension centre steel pipe.
Compared with prior art, its advantage is the present invention：
1st, the inventive method, common sheet material suspension centre structure is replaced with cylindric suspension centre steel-tube construction, the smooth no rib in surface,
Abrasion to lifting-steel-rope is small, increases the service life of lifting-steel-rope.
2nd, the inventive method, single lifting-steel-rope can pass around multiple suspension centre steel pipes so that every cable wire uniform force simultaneously subtracts
Few cable wire, avoids single cable wire from exceeding safe working load, securely and reliably.The increase of the contact area of steel pipe and cable wire, suspension centre knot
The associated contact area of structure and barge also increases, and facilitates load to be delivered to full ship so that longitudinal bulkhead, transverse bulkhead of the load to barge
Upper limited transmission, protection barge are unlikely to deform in lifting, are broken.
3rd, the inventive method, single lifting-steel-rope reduce steel cord ends " eye splice " quantity, unloaded around multiple suspension centre steel pipes
Quantity is detained, so as to improve efficiency, save cost.Meanwhile the use of lifting-steel-rope so that the stress on single lifting-steel-rope is corresponding,
Avoid because some steel wire rope unbalance stress cause steel wire rope to be broken suddenly.
4th, the inventive method so that lifting-steel-rope can adjust self-view and protected with lifted weight thing according to weight inclination conditions
Maintain an equal level weighing apparatus, more safer than tradition.
5th, rope-winding method of the invention, outwards radially distributed by center so that weight is smaller by cross force, security
Can be high.Uniform force on each lifting-steel-rope, same root steel wire rope pass around some suspension centre structures, and steel wire rope can automatically adjust flat
Weighing apparatus, it is not required to adjust angle, simple operation, and steel wire rope and suspension centre structure stress are uniform, security performance is higher, reduces shackle number
Amount, it is cost-effective.
