Description
Technical field
Petroleum and natural gas drilling equipment technical field is the utility model is related to, more particularly to a kind of twin-roll that is applied to twists
The rope hoisting device of car.
Background technology
During petroleum machinery equipment and hoisting operation, rope hoisting system frequency of use is very high, most of to use
Winch is divided into single drum winder and double-drum winch as lifting means, hoisting gear according to cylinder number, wherein, twin-roll twists
Car refers to drive by a unified drive mechanism, the winch of the grooving with different rotation directions on same reel, two
One end of boom hoist cable is respectively wound around on reel with being adapted direction with grooving, and is fixed on the both ends of reel, steel wire rope
The object that is lifted of the other end and needs or pulley be connected and fixed to dead line end；Twin-roll hoisting gear has two rollings of major-minor
Cylinder, such as master rotor forward direction rope woolding, auxiliary cylinder is with regard to reverse rope woolding, and when winch forward direction turns, master rotor steel wire rope is packed up, auxiliary cylinder
Steel wire rope rope closing, similarly if opposite direction, master rotor puts rope, and auxiliary cylinder puts rope, and double-drum winch passes through motor or motor
Driving, moving up and down for object is realized by rotating；In order to improve the service life of steel wire rope, cable lay and grooving side
To should be consistent, i.e. steel wire rope tightly twists direction, ensures in steel wire rope in motion process, steel wire rope wound upon themselves are increasingly
Tightly, so as to improving the service life of steel wire rope.
Above-mentioned wire rope device completes object and lifting and decentralization by two kinds of steel wire ropes, and this is required in winch rope woolding
During, it is necessary to assure the length of two steel wire ropes is the same, otherwise can be caused in use between two steel wire ropes
Discontinuity, it is unfavorable for the life-span of steel wire rope, if two boom hoist cable length difference are excessive, two steel wire ropes can be caused
In only a stress, not only accelerate the abrasion of steel wire rope, it is also possible to bring unbalance loading serious, structure stress damage, steel wire rope
The potential safety hazards such as fracture.During rope woolding, it is ensured that the length of two steel wire ropes is completely the same, is extremely difficult, meanwhile,
In use, because steel wire rope material, loading conditions, service condition etc. can not be completely secured unanimously, steel wire rope is caused
The numerous reasons of elongation difference, etc. may all cause steel wire rope stand under load unbalanced after stand under load, in order to solve the above problems, generally
Method be increase steel wire rope regulation and tensioning apparatus, ensureing the length of steel wire rope can adjust in certain scope, no matter
It is which kind of steel wire rope regulation and tensioning apparatus, after it adjusts rope capacity, the inclined of steel wire rope can only be reduced to a certain extent
Load situation, the unbalance loading of steel wire rope, the regulation of increase steel wire rope or tensioning apparatus can not be inherently eliminated, mechanism is added, ties
Structure complicates, and adds manufacture, Operation and maintenance cost；Another method is to use the otic placode of oscillation bearing in dead line end
Form connects, using etc. the lever of brachium the dead line end of two steel wire ropes is connected, cause stress when rope capacity is inconsistent
When uneven, two rope capacities are adjusted by the swing of dead line end, although this method can solve two steel wires
Restrict unbalance stress the problem of, but during for wirerope-winding, two rope capacity deviations and winding tightness deviation etc.
It is required that it is still higher, and adjusting range is limited, it is poor for applicability for big deviation, if deviation is big between steel wire rope, equiarm
The brachium of lever just needs long, and the volume of total can increase, and be unfavorable for arranging.Meanwhile using this kind of structure, easily
Steel wire rope is produced during being lifted and transferring weight to rock, brachium is longer to be rocked more serious, has a strong impact on lifting safety.
To solve the above problems, need to invent a kind of rope hoisting device, for realizing that rope capacity is inconsistent
Adjustment, fundamentally solve the uneven situation of steel wire rope stand under load and ensure that steel wire rope rotation direction is consistent with reel deep trouth rotation direction simultaneously,
Improve the service life of steel wire rope.

Technical Analysis：
The utility model is lifted and transferred object using double-drum winch, and double-drum winch is by two different rotation direction groovings
Roller composition, in order to improve the service life of steel wire rope, steel wire rope is consistent with the direction of grooving, using two different rotation directions
For wirerope-winding on reel, the length of steel wire rope is longer and has certain elasticity, therefore during steel wire rope rope woolding, two
The length of steel wire rope easily produces fine distinction, and double-drum winch uses identical drive mechanism and two in the utility model
The deep trouths of individual different rotation directions is processed on a reel, therefore the decentralization of two steel wire ropes and recovery are synchronous, and two steel wires
The nuance of length can cause steel cable loose between rope, and steel cable is tight, or the physical attribute of two steel wire ropes has
Difference, or two one, steel wire ropes are old steel wire rope, one is new steel wire rope, and elongation is different after stand under load, also results in
A piece cord pine, steel cable is tight, this especially under heavy duty so as to cause discontinuity between two steel wire ropes
Situation is breakneck, may cause the damage of steel wire rope or more than rupture pull force, so as to which major accident, this practicality occur
New that two steel wire ropes are connected into steel cable by fixed pulley assembly, the stress on same root steel wire rope is identical,
If there is the above situation, unbalance loading causes two steel wire rope under tensions different, in the presence of the two pulling force differences, fixed steel
The fixed pulley of cord rotates, and reduces the different phenomenon of two tightness of steel wire rope, until pulling force is identical between two steel wire ropes,
Fixed pulley is not rotated further by, the different situation of stress between completion two steel wire ropes of adjustment, and during adjustment, steel wire rope
Movement be along rope hoisting and decentralization track move, will not produce it is horizontal rock, if due to two steel wire ropes it
Between the steel wire rope stand under load caused by reason such as physical state difference after elongation it is different, can also be by the rotation of fixed pulley come complete
Into adjustment, the pulling force being subject to for ensureing two steel wire ropes is identical.Ensure the security reliability during lifting.
Beneficial effect：
1st, the device is linked together the steel wire rope of two different rotation directions by fixed pulley at dead line end, such two steel
The inconsistent adjustment of rope capacity is realized by the rotation on fixed pulley between cord；
2nd, because two steel wire ropes link together, therefore fundamentally solves the uneven situation of steel wire rope stand under load, simultaneously
It also ensure that steel wire rope rotation direction is consistent with reel deep trouth rotation direction, improve service life of steel wire rope；
3rd, compared with prior art rope hoisting device, the utility model rope hoisting apparatus structure is simple, does not increase
Add other mechanisms, reduce Operation and maintenance cost.
