Abstract
The invention relates to a method and a device for keeping tension balance among strands while twisting wire rope, which aims to solve deficiency in regulating tightness of a damp tape by bolts, and the problem of tension imbalance among strands. The invention is mainly characterized in that a manual hydraulic damp device is disposed on the strand coiling frame of the rope forming machine, a piston rod tightens up the damp tape through a lever, increases positive pressure applied on a damp wheel by the damp tape, increases moving resistance of a strand coiling wheel, consequently increases tension of strand on the strand coiling wheel, and reduces tension of the strand on the contrary until the requirement is met. Tension of strand on each strand coiling wheel is adjusted according to the pressure display value of the hydraulic oil cylinder, so as to make them in accordance. The method and the device enhances quality of the wire rope twisting, prolongs life of the wire rope, and can be applied on basket type rope forming machine of various kinds.
Description
Technical field
The invention belongs to Wire Rope Production and make the field, mainly relate to the steel wire rope rope-forming machine when the twisting steel wire rope, use hydraulic cylinder tension damping tape, a kind of method and device of each rope strand balancing tension when keeping twisting wire rope of adjusting each strand tension force.
Background technology
Producing multistrand rope at present, is to be formed by a plurality of rope strand twistings, and the balanced intensity of each rope strand tension force is directly connected to the presentation quality and the bearing capacity of steel cable when twisting.The balancing tension that has only each strand, it is stressed that evenly steel wire rope is the stressed unanimity of each strand in use, and bearing capacity increases.Otherwise the tension force of each strand is unbalanced, and the stressed inconsistent of each strand can appear in steel wire rope in use, varies, and stressed big elder generation is disconnected.This situation occurring will influence the bearing capacity of whole piece steel wire rope, shortens the life cycle of steel wire rope.Keeping each strand of steel wire rope tension force at present is to realize with the degree of tightness of adjusting bolt adjustment damping tape.Only, judge the degree of tightness of damping tape, infer the size of each strand tension force with operator's sensation and experience.
Summary of the invention
The purpose of this invention is to provide a kind of method and device of each rope strand balancing tension when keeping twisting wire rope, this method can guarantee the balancing tension of each personal share of steel wire rope quantitatively, improves whole rope tension of steel wire rope and product quality.
The present invention is achieved by the following measures, its method is, utilize manual hydraulic damping device, when the piston rod of bobbin loader upper cylinder stretched out, by lever tension damping tape, the increase damping tape acted on the normal pressure on the damping wheel, increase the resistance of motion of drum wheel, increase the drum wheel and go up the tension force of rope strand, otherwise then reduce the tension force that the drum wheel is gone up rope strand, reach till the technological requirement; Because it is relevant with the pressure of hydraulic oil in the hydraulic jack that the drum wheel is gone up the size of rope strand tension force, by the size of hydraulic jack upward pressure display unit numerical value, adjust the tension force that each drum wheel is gone up rope strand, make its unanimity of keeping in balance.
The hydraulic damping device of realizing above method is on the drum wheel of each bobbin loader of steel wire rope rope-forming machine, to be provided with damping wheel; One end of damping tape is fixed on the bobbin loader, after the other end is walked around damping wheel, locks onto an end of terminal pad; The bearing of terminal pad is fixed on the bobbin loader.The hand-hydraulic oil cylinder is installed on the bobbin loader, is positioned at same plane with damping wheel, and the piston rod of hydraulic jack is connected with the other end of terminal pad, and pressure-display device is housed on the hydraulic jack.In order to make the stressed even of drum wheel,, a cover hydraulic damping device is set respectively in the both sides of each drum wheel.
The invention has the beneficial effects as follows, can guarantee the balancing tension of each strand of steel wire rope, improve the quality of twisting wire rope, prolong the service life of steel wire rope.Can be applicable on all kinds of basket type rope-forming machines.
Description of drawings
Fig. 1 is a structural representation of the present invention, and Fig. 2 is the partial enlarged drawing of Fig. 1, and Fig. 3 is the vertical view of Fig. 1.Among the figure 1 for drum wheel, 2 be damping wheel, 3 for damping tape, 4 for bobbin loader, 5 for the damping tape fixed axis, 6 for terminal pad, 7 for buckle, 8 for axle bed, 9 for support, 10 for pressure-display device, 11 for hydraulic jack, 12 for bearing, 13 is the hydraulic jack support, I is the partial view position.
