Description
The utility model relates to a kind of winding mechanism of wire rope, is specially adapted to row's silk mechanism of the finer wire in the oilfield well testing equipment lifting system.
In the Hoisting System of the various well testing equipments in oil field, often need be on cylinder the wire rope of writhing number km, the end place is connected with instrument during well logging, the wire rope that discharges with cylinder is the shaft bottom at 4000～7500 meters to well depth down, testing arrangement by instrument and ground is measured down-hole pressure, temperature, the degree of depth ... etc. data, after testing, again wire rope is rewinded on the cylinder, prepare the test of next well, this mechanism by cylinder winding and release wire rope is called row's silk mechanism, in existing technology, the row's silk mechanism that is used for the well testing equipment Hoisting System has two kinds, a kind of is artificial row's silk, along with the rotation of cylinder, twines release with manually hauling steel wire on cylinder, its labour intensity is big, inefficiency.Another kind is by machinery row silk, what China adopted at present is that positive left-hand thread monofilament thick stick formula is arranged silk mechanism, this mechanism is: have one the leading truck of helping steel wire is housed on the leading screw of positive left-hand thread thread groove, one special construction is housed in leading truck and is equivalent to the guide runner of screw, be entrapped in the thread groove of leading screw and the garden by the positive left-hand thread infall in leading screw two ends slips over aqueduct, make guide runner enter left-hand thread thread groove (otherwise perhaps) from the plus thread groove.When power by cylinder, index change gear when driving leading screw and rotating, because its slide block of structural constraint can not rotate with leading screw, and is promoted along the leading screw axis by threads of lead screw, makes it to drive leading truck and moves back and forth along leading screw.Though this kind row silk mechanism can be wound into wire rope on the cylinder by mechanical movement, multi-level proper alignment that can not steel wire is very desirable is on cylinder.This be because: at first be that steel wire diameter exists error, the accumulated error of arranging on cylinder very is considerable, next is a leading screw helical pitch effective length sum of errors cylinder mismachining tolerance of holding the silk width dimensions etc., because the accumulated error that various factors produces can not effectively be got rid of, therefore in the reciprocating motion process of winding steel wire, when accumulated error reaches certain limit, steel wire will break away from the constraint of guiding device, cause irregular disorderly row, extruding appears and the phenomenon of collapse repeatedly (steel wire is leading or hysteresis with respect to cylinder), the random steel wire of row produces plastic strain under pulling force, be prone to impaired fractureing and possibility of accident occurrence has a strong impact on the application life of steel wire, and caused the difficulty that discharges steel wire when going into the well.
The purpose of this utility model provides a kind of novel row's silk mechanism, input by the differential compensation error motion can both automatically be recompensed to the error of the accumulation of various factors generation, thereby can realize that steel wire carries out the effect of multi-level proper alignment on cylinder, improve operating efficiency, and prolonged the application life of steel wire.
