Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Accompanying drawing is structural representation of the present invention.
Embodiment
As shown in drawings, big-length of the present invention, the three-dimensional strand of heavy in section high pressure photoelectric composite sea cable body back twist cabler comprise pallet driving motor 2, machinery rotation bearing 3, variable-frequency motor 4, electric floating bearing 5, electric installation 6, strand body PLC system 7 or main PLC control system 10, back twist system 8, bus cable device 9.Described pallet driving motor 2 passes through bevel type gear on strand body rotating disk 1, extremely large-scale 8m pallet of Spur Gear Driving, then makes pallet rotation by machinery rotation bearing 5.Pallet variable-frequency motor 4 is controlled by electric installation 6 according to the signal of the main PLC control system 10 of interlock or single action strand body PLC control system 7, obtains theory given, relies on electric floating bearing 5 to realize pallet rotation.By back twist system 8, pallet speed is carried out to the closed loop Anhui musical styly more in process of production, realize automation control.
Native system will be placed in multiple pallets on strand body rotating disk 1, as take-up again as unwrapping wire, can reduce half pallet or portal frame quantity, realize receive more and put more, and reduce costs; The present invention only need configure three pallets, winding displacement arm 11 and draw-gear, be equivalent to only there is a set of take-up, bus cable device 9 and three cover unwrapping wire, back-twist devices, just can realize big-length, the production of heavy in section high pressure photoelectric composite sea cable, 5M pay off rack also can be installed simultaneously on pallet and produce short length sea cable, realize a tractor serves several purposes, reduced cost of investment.
Adopt pallet to realize the take-up course of work as follows:
Vertical strand body pallet 1 is produced with the synchronous interaction of upper operation sheath machine, and upper planning sheet core sea cable is turned to hauling machine, turning rack, creel stand, entered 8M pallet automatic winding displacement by sheathing.Described hauling machine is mounted in a hauling machine on sheathing production line High Altitude Platform, realize cable pulling to automatic winding displacement frame by synchronizeing with sheath machine rear haulage, described turning rack is mainly by support, the angled automatic winding displacement frame that enters of mistake line rod wheel shape.
Described automatic winding displacement frame is mainly made up of automatic winding displacement apparatus 9, it comprises pin joint, screw mandrel hoisting mechanism, winding displacement arm 11 and automatic winding displacement bogie, screw mandrel hoisting mechanism is fixed on travelling car by pin joint, be connected one end of winding displacement arm 11 of the other end of screw mandrel hoisting mechanism, this winding displacement arm 11 can move up and down and can rotate in the horizontal direction under the drive of screw mandrel hoisting mechanism, and the other end of described winding displacement arm 11 arranges automatic winding displacement bogie; Draw-gear for cable transfer is also fixed on base by column.
8M pallet rotates in the scope passing in and out to winding displacement arm 11 by strand body rotating disk 1, removes active pay off rack, installs pallet inner core additional and forms a rotating pallet body, adopts the rolling speed of variable-frequency motor control pallet.
Pallet is in the time rotating with constant speed, and the residing annulus girth of tray edge is the longest, and the girth of the upper any point annulus of living in pallet middle part is shorter, thereby the linear velocity of the upper any point of tray edge and pallet middle part is different.In the time of take-up, the residing position of cable is inevitable is not a fixed position on pallet all the time, and therefore the linear velocity of cable take-up is inconsistent, and this will exist nonsynchronous problem.
The present invention solves by the following technical programs: adopt position transducer to detect the position of winding displacement arm 11, the data of detection pass to PLC control system.Because the position of winding displacement arm 11 is corresponding with the cable of take-up on pallet, winding displacement arm 11 is in the time of tray edge, and on pallet, cable is also received to tray edge; Winding displacement arm 11 is in the time of pallet middle part, and on pallet, cable is also received to pallet middle part.The relation that we just can be corresponding according to this position like this, adopts the position of detecting winding displacement arm 11 to detect cable take-up position on pallet, controls the rotating speed of pallet according to take-up positions different on pallet, keeps cable to keep constant linear velocity take-up.
Particularly, PLC control system is controlled variable-frequency motor according to the data that detect, and realizes the control to pallet velocity of rotation, makes cable keep constant linear velocity take-up.
So not only satisfactorily resolve sabot amount and synchronous take-up problem, and solved upper operation to this operation and have enough to meet the need.The present invention adopts pallet take-up, can reduce to greatest extent extra large cable joint quantity, meets big-length sea cable and produces.As: the single non junction length of single core 110kV sea cable exceedes 50km, and single core 220kV sea cable at least reaches 35km.
Adopt the vertical setting-out work process of pallet as follows:
No matter be that horizontal or vertical single-core cable must complete back twist in various degree in stranding process, just can reach the stress that reduces cable itself.Pallet unwrapping wire is because cable is to keep flat in the plane, and the torsion due to cable own in revolution back twist exists, and it is not reach cable requirement far away that single dependence rotating disk is followed back twist.The present invention has increased variable-frequency motor 4 and back twist system 8 newly under traditional back twist prerequisite, comprises mechanical back twist and electric back twist.
Machinery back twist cardinal principle is that pallet is followed strand body rotating disk 1 and rotated, and 1 time pallet that turns around of strand body rotating disk returns and turns around.Be specially by strand body rotating disk 1 transmitting gear and reach pallet, pallet relies on machinery rotation bearing 3 to rotate, and reaches rotating disk and returns the pallet that turns around and return the object turning around.
Electric back twist is mainly in mechanical back twist, to rely on back twist system 8 to detect online cable, by detect back twist rate data feedback to PLC control system, PLC control system compares according to the back twist rate of setting, by relatively drawing actual back twist rate, according to calculating deviate, variable-frequency motor is carried out to the adjustment of transmission closed loop again, put thereby overcome penetrating of cable self torsion in pallet unwrapping wire process.
The computing formula of back twist rate is: K%=(S1/S2) × 100%, wherein S1 is back twist speed, S2 is the rotating speed of cantilever bow.After stranded, the pitch of core conductor is divided by the pitch of stranded front core conductor, and being then multiplied by is absolutely exactly back twist rate.Therefore, the detection of back twist rate is the general knowledge of this area, in the present invention, repeats no more.
Device of the present invention has solved that prior art design is unreasonable, electrifing degree is low, once produce single non junction length short, take up an area the technical problems such as space is large.Vertical strand body pallet can carry out adjusting with online from motion tracking according to operating personnel's back twist set point.Eliminate because not having back twist to cause the cable stress concentration phenomenon of generation completely.
Above-described embodiment does not limit the present invention in any way, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in protection scope of the present invention.
