Description
The double-drum winch lifting system and rope of variable rope system are transform method
Technical field
The present invention relates to technical field of oil drilling equipment, it is device that specifically a kind of drilling machine traveling system, which becomes rope,.
Background technology
Semisubmersible drilling platform is the sharp weapon of deep-sea oil gas resource exploration and development, and a large amount of new technology is on semisubmersible platform
It emerges from.For hoisting system of rig, lifting system and conventional lift on more universal semisubmersible drilling platform now
System is similar, including winch, traveling system and derrick, and rope is constant in lifting system, and efficiency is constant, and device redundancy is relatively low；
Since semisubmersible platform is influenced to occur heaving variation by stormy waves stream, to ensure that drillng operation is normally carried out, heave compensation dress
Set becomes standard configuration on platform, and more universal mode is the increase overhead traveling crane fixed pulley in traveling system overhead traveling crane fixed pulley group at present
Group compensation device, but the device is located at crown, and platform entirety center of gravity can be caused to increase, and stability reduces.
Oil-well rig travelling system is answered by the fixed pulley of overhead traveling crane and the movable pulley of tourist bus by what wirerope-winding formed
Pulley system, variable rope system formula traveling system are made of an overhead traveling crane and multi-section single-sheaved block tourist bus, can in drilling process basis
Different drilling conditions ensure roller by the way that the pairs of symmetry transformation of single-sheaved block tourist bus is converted rope system at fixed pulley or movable pulley
Winch motor is run in high efficient district always, improves operational efficiency.If carrying out using people completely when transformation rope is in traveling system
Work is operated, and heavy workload, working efficiency is low, and danger coefficient is high.So becoming the automation mechanized operation and control just that rope is device
It is particularly important.
Invention content
It is transform method the object of the present invention is to provide a kind of double-drum winch lifting system of variable rope system and rope, it can
Fast and automatically change the transformation for realizing lifting system rope system, to improve raising efficiency and device redundancy, solves manual operation work
Amount is big, the low problem of efficiency.
To achieve the above object, the technical solution used in the present invention is：
A kind of double-drum winch lifting system of variable rope system, it includes mounted on the day vehicle frame on derrick top, by several portions

End is hinged with tourist bus hook, and the rear end of second connecting rod is hinged on the side plate of single-sheaved block tourist bus, and the bottom end of third connecting rod is hinged on
On second connecting rod, the top of third connecting rod and the bottom end of guide rod are hinged, and the top of guide rod is equipped with resetting spring, at resetting spring
In tension；The top of guide rod is adjacent and coplanar with the piston end bottom of the second cylinder, several the second cylinders being arranged side by side
Mounted on the outside of locking beam.
Preferably, two fewer than the quantity of single-sheaved block tourist bus of the quantity of second cylinder.
Preferably, the direction that the first connecting rod is rotated with second connecting rod junction and tourist bus hook hook lock opening direction phase
Instead, block is equipped on the outside of the tie point of first connecting rod and second connecting rod.
Preferably, the bottom of the gusset is equipped with guider.
Preferably, the locking beam by lower wing plate there is the welded H section steel of difference in height to be prepared.
Preferably, one end is fixed on the steel wire rope on the one of roller of double-drum winch and bypasses on day vehicle frame
Leading block passes through the single-sheaved block tourist bus in fixed pulley and movable pulley tourist bus group in fixed pulley group successively, then passes through another two
A leading block winds and is fixed on another roller of double-drum winch, fixed pulley group, the composition travelling of movable pulley tourist bus group
System.
Preferably, homonymy rope stretching of the steel wire rope from fixed pulley group.
A kind of double-drum winch lifting system rope system transform method of variable rope system is made of dynamic several single-sheaved block tourist buses
For pulley tourist bus group under the cooperation of top locking device and lower part hook lock device, the single-sheaved block tourist bus position for controlling different number is solid
Being scheduled on the bottom of top locking device becomes fixed pulley, carries out the rope system transformation of lifting system, and detailed process is：
Step 1: under the action of double-drum winch, all single-sheaved block tourist buses, which synchronize, moves up common operational promotion
Tourist bus holder and top drive, in addition to outermost two single-sheaved block tourist buses, other single-sheaved block tourist buses with top locking device phase
It is in contact at the top of contact, the bottom end of the second cylinder and the guide rod inside single-sheaved block tourist bus corresponding thereto；
Step 2: double-drum winch is rotated further, outermost two single-sheaved block tourist buses will promote tourist bus holder and top is driven
Continue to rise, until outermost two single-sheaved block tourist buses stop operating after being contacted with top locking device, at this time tourist bus holder with
Tourist bus hook positioned at intermediate single-sheaved block tourist bus disengages contact, is convenient for the opening of tourist bus hook hook lock；
Step 3: the piston end that operating personnel controls the first cylinder in the locking device of top stretches out, at the top of piston end
Lock clasps intermediate two single-sheaved block tourist buses, and intermediate two single-sheaved block tourist buses are fixed on the bottom of top locking device；Operation
The piston end that personnel control top locking device is located at two intermediate the second cylinders stretches out, and pushes intermediate two single-sheaved block tourist buses
