Abstract
A strand tension control device for twisting a steel wire rope comprises a pulling rope (1) and a damping wheel (3) rotationally connected onto a bobbin loader (2), wherein one end of the pulling rope (1) is fixed below the bobbin loader (2); a cylinder (4) is arranged above the bobbin loader (2); and the other end of the pulling rope (1) extends along the peripheral surface of the damping wheel (3) and is connected with a piston rod of the cylinder (4). Compared with the prior art, the strand tension control device for twisting steel wire rope has the characteristics of higher tension control accuracy, better use stability and better quality of a prepared finished product.
Description
Technical field
The utility model belongs to steel cable production equipment field, particularly relates to a kind of twisting wire rope thread tenslator.
Background technology
The steel wire rope of producing at present, is to be formed by steel wire strand rope strand twisting, and when twisting, the rope strand tension force of each group draw drum needs identical and even, otherwise Quality of Steel Wire Rope after preparation cannot reach required requirement, and yield rate is lower.The twisting wire rope thread tenslator of prior art, by adjusting nut and spring, carry out the draught line free end of damping adjusting wheel, or the draught line free end of taking turns by manual lead screw damping adjusting, realize different dampings, to control the tension force of rope strand on each strand of Loosen up wire wheel, but the tension force of these two kinds of regulative modes is controlled and is all relied on artificial qualification, the complete armrest sense of Tensity size, therefore be affected by human factors large, tension force control accuracy is low, and can not follow the tracks of each strand of tension force of adjustment rope-forming machine by real-time online, thereby the uniformity that causes steel wire rope poker, flatness, glacing flatness and structural stability all can not be guaranteed, and then presentation quality and the bearing capacity of steel wire rope have been affected, greatly shortened the service life of steel wire rope, also fraction is by electrical system, to carry out the draught line free end of damping adjusting wheel, and be provided with control module and measuring transducer, realize automatically and controlling, but due to governor motion employing is the combination of motor and tooth bar, having relatively high expectations to motor, otherwise easily there is situation about burning out in motor, and also need motor output compared with high pulling torque, otherwise more difficult band carry-over bar, and easily there are wearing and tearing in tooth bar, stability in use is poor, and then cause degree of regulation deviation larger, therefore also just affected presentation quality and the bearing capacity of steel wire rope, greatly shortened the service life of steel wire rope.
Utility model content
The utility model provides a kind of tension force control accuracy higher for above problem, and stability in use better and the good twisting wire rope thread of the end product quality tenslator of preparation.
The utility model overcomes the above problems, technical scheme used is: a kind of twisting wire rope thread tenslator is provided, it comprises pull rope and is rotatably connected on the damping wheel on bobbin loader, one end of described pull rope is fixed on bobbin loader below, the top of described bobbin loader is provided with cylinder, and the other end of described pull rope extends and is connected with the piston rod of cylinder along damping wheel outer peripheral face.
Adopt after above device, compared with prior art, the utility model is owing to adopting cylinder to regulate, and cylinder is because of the feature of himself, have stable, extension and contraction control is better, is not prone to the situation of wearing and tearing in use procedure, therefore the precision while regulating is higher, thereby guarantee uniformity, flatness, glacing flatness and the structural stability of steel wire rope poker, and then making the quality of finished product steel wire rope better, steel wire rope bearing capacity is higher, and improves the service life of steel wire rope.Therefore the utlity model has tension force control accuracy higher, stability in use better and the good feature of end product quality of preparation.
As improvement, described bobbin loader below is provided with support, described support is provided with through hole, and in through hole, be provided with screw rod, the diameter of described screw rod is less than the diameter of through hole, the length of screw rod is greater than the length of through hole, and the two ends of screw rod are all positioned at through hole outside, one end of described screw rod is connected with one end of pull rope, and the screw rod at through hole two ends is provided with for spacing nut, after this structure arranges, make in use, pull rope relaxes because easily there is for a long time creep under stress shape, now unclamp nut, by screw rod to drawing and make pull rope again exceptionally straight away from damping wheel direction, again locking nut subsequently, this facilitates the adjusting of pull rope, and without adjusting cylinders position, after once no person's cylinder location regulates, need to reset the parameter of control module, regulate trouble, regulating cycle is longer, therefore can shorten the regulating cycle of the utility model pull rope, and then enhance productivity.
As further improvement, one end of described pull rope is pin with the other end of one end of screw rod and pull rope and the piston rod of cylinder and is connected, after adopting pin to connect, when changing pull rope, only pin need be extracted, take off the pull rope that needs replacing, put new pull rope, and reinsert pin, change more convenient.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model twisting wire rope thread tenslator.
As shown in the figure: 1, pull rope, 2, bobbin loader, 3, damping wheel, 4, cylinder, 5, support, 6, screw rod, 7, nut.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1, a kind of twisting wire rope thread tenslator, it comprises that pull rope 1 and the damping wheel 3(being rotatably connected on bobbin loader 2 also comprise other parts certainly, but do not create utility model point owing to relating to the utility model, therefore do not repeat them here), one end of described pull rope 1 is fixed on bobbin loader 2 belows, the top of described bobbin loader 2 is provided with cylinder 4, the other end of described pull rope 1 extends and is connected with the piston rod of cylinder 4 along damping wheel 3 outer peripheral faces, certainly be also provided with electromagnetic proportional valve, electromagnetic proportional valve is on the pipeline between source of the gas and cylinder, and electromagnetic proportional valve is connected with the control decorum.Cylinder 4 on general a plurality of bobbin loader is used same gas source feed, can guarantee like this uniformity of the action of each cylinder 4 when regulating, and then guarantees degree of regulation.
Described bobbin loader 2 belows are provided with support 5, described support 5 is provided with through hole, and in through hole, be provided with screw rod 6, the diameter of described screw rod 6 is less than the diameter of through hole, the length of screw rod 6 is greater than the length of through hole, and the two ends of screw rod 6 are all positioned at through hole outside, and one end of described screw rod 6 is connected with one end of pull rope 1, and the screw rod 6 at through hole two ends is provided with for spacing nut 7.
One end of described pull rope 1 is pin with the other end of one end of screw rod 6 and pull rope 1 and the piston rod of cylinder 4 and is connected.
During use, the Data Control electromagnetic proportional valve that control system is passed back according to sensor, and then control cylinder 4 piston rods is flexible, to make pull rope banding or unclamp damping wheel 3, thereby realize different dampings, to reach the object of controlling the tension force of rope strand on each strand of Loosen up wire wheel.
Above embodiment is only preferred embodiment of the present utility model, and the utility model is not limited only to above embodiment and has also allowed other structural change, as: cylinder also can adopt oil cylinder to replace; The two ends of pull rope are bolted etc., allly in the utility model rights to independence claimed range, change, and all belong to the utility model protection domain.
