Abstract

The utility model relates to a wirerope prestretcher which comprises a line casting machine, a wire receiving machine, a wire discharging device, an oil bath, a fixed and tight end, a bogie link, a tension oil cylinder, a speed reducer and a motor. The utility model adopts segmented and repeated tension, and the power for pulling and tightly holding the wirerope adopts hydraulic power. The working procedure is that an H-wheel of the line casting machine releases the wirerope through the fixed and tight end and a cable groove to reach a guide wheel, then the wirerope goes round the guide wheel through the cable groove to reach a movable and tight end, and at last the wirerope is greased by the oil groove to be rolled on a procedure wheel of the wire receiving machine through the wire discharging device. The diameter scope of the pulling wirerope of the wirerope prestretcher is large, the structural stretch and the twisted stress of the wirerope is eliminated, and the service life is increased.

Description

The pre-stretch-draw machine of steel wire rope

The utility model relates to industrial steel wire rope apparatus field.

Steel wire rope is at the use initial stage and since strand with strand between, between steel wire and the steel wire, strand and wire rope core between all have the slit, use the stress of eliminating steel wire rope when stressed and gap and produce permanent structure and extend.Some occasion steel wire rope because structural stretch is forced to stop production and is adjusted rope capacity two, three times, has a strong impact on operating efficiency in one month initial stage of use.The domestic pre-stretch-draw of steel wire rope mechanism is a continous mode at present, and its maximum pull is tens tons, and only being used for the stretch-draw diameter is the following elevator ropes of 20mm.The wirerope diameter scope of stretch-draw is little, strand wire and steel wire rope discontinuity, and fatigue life is low.

The purpose of this utility model provides a kind of sectional type pre-stretch-draw machine of stretch-draw repeatedly that adopts, and is big to reach stretching wire rope diameter range, and stressed during steel wire rope stretch-draw evenly the elimination steel cord structure extends, and improves the steel wire rope purpose of fatigue life.

The technical solution of the utility model is such: this stretch-draw machine comprises paying out machine, admission machine, strand oscillator, oil groove, fixedly holds end, link, pull action cylinder, decelerator, motor tightly, paying out machine, admission machine, decelerator, motor are all installed on the electric flatbed tricycle, motor is connected with admission machine by decelerator, the strand oscillator of steel wire rope proper alignment that can stretch-draw is intact and admission machine interlock.Fixedly hold tightly on the end mounting seat, activity is held end tightly and is fused by link and oil cylinder.Fixedly holding end and activity tightly holds end hydraulic means identical by nine respectively, that maximum thrust can reach 200KN tightly and is disposed in order and forms.Fixedly hold tightly the end and end and paying out machine are held in activity tightly, all at same end, guide wheel is placed in the other end to admission machine.The utility model adopts sectional type stretch-draw repeatedly, stretch-draw and the power employing hydraulic power of holding steel wire rope tightly.The operation of stretching wire rope is: the I-beam wheel of paying out machine is emitted steel wire rope, arrives guide wheel through fixedly holding end and grooving tightly, and steel wire rope is walked around guide wheel and held end tightly through grooving arrival activity again.Through the oil groove oiling, fitly twist in by strand oscillator on the I-beam wheel of admission machine.

The utlity model has following advantage:

1. stretching wire rope diameter range is big, and the wirerope diameter scope is between the 20mm-65mm, and stretching force is adjustable arbitrarily at 50-1500kn, and intensity is not more than 1870MPa.

2. according to the instructions for use difference of steel wire rope, can reach part or thoroughly eliminate its structural stretch, accurately record rope capacity.

3. the pre-stretching force of the utility model is the 40-60% of breaking force of rope, by stretch-draw repeatedly, has eliminated the twisting stress of steel wire rope, makes strand wire and steel wire stressed evenly, thus the fatigue life and the hungry service life of having improved steel wire rope.

4. because stretching force exceeds 2-5 doubly than steel wire rope real work load,, guarantee the outgoing of steel wire rope so in stretching process, can in time find the defective that may exist in the twisting.

5. the utility model arrangement floor space is little, has reduced handling equipment, has improved the work utilization rate, has reduced operating cost.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is that A of the present utility model is to the section schematic diagram.

Embodiment of the present utility model is illustrated in conjunction with the accompanying drawings.

As shown in Figure 1, each parts of the present utility model are: 1-paying out machine 2-admission machine 3-strand oscillator 4-oil groove 5-base 6-fixedly holds end 7-grooving 8-guide wheel 9-activity tightly and holds end 10-link 11-pull action cylinder 12-decelerator 13-motor tightly.

Paying out machine 1, admission machine 2, decelerator 12, motor 13 are installed on the electric flatbed tricycle, and motor 13 is connected with admission machine 2 by decelerator 12.The strand oscillator 3 of steel wire rope proper alignment that can stretch-draw is intact and admission machine 2 interlocks are fixedly held end 6 tightly and are installed on the base 5, and activity is held end 9 tightly and fused by link 10 and oil cylinder 11.Grooving 7 is relatively independent members, is used for the steel wire rope of support stretching process.Guide wheel 8 plays turn back 180 ° effect of steel wire rope.Oil groove 4 is used for the steel wire rope that stretch-draw is intact and coats required grease by user's difference requirement.Oil cylinder 11 is the hydraulic system executive component, and maximum stretching force can reach 1500KN, and range is 2.5M.The course of work of the present utility model is: will need the steel wire rope of stretch-draw to place on the paying out machine 1, by another set of haulage gear steel wire rope is pulled out, by fixedly holding end 6, grooving 7 tightly, be diverted to opposite side grooving 7 successively, hold end 9, oil groove 4, strand oscillator 3 tightly to admission machine 2 through activity through guide wheel 8.Start and fixedly hold end 6 and movable hydraulic system of holding end 9 tightly tightly, the steel wire rope two ends of need stretch-draw are held tightly; Start the hydraulic system of oil cylinder 11, oil cylinder 11 drive activities are held end 9 tightly and are moved to the admission machine direction by setting value of thrust, unloading after under tensile state, stablizing a period of time afterwards, end 9 and oil cylinder 11 motion round about under the steel wire resilient force are held in unloading back activity tightly, can measure the steel cord structure elongation after stopping, this operation sequence repeatedly, until the value of making it, the stretch-draw of this section rope is promptly accused and is finished.After starter motor 13 drive admission machines 2 steel wire rope that this section stretch-draw is intact passes through oil groove 4 oilings, fitly come on the admission machine 2 through strand oscillator 3.Can carry out the stretching piecemeal of back steel wire rope according to aforesaid operations, the whole stretch-draw of the steel wire rope on admission machine 1 are intact, and the pre-stretch-draw machine operation of whole steel wire rope is finished.

Fig. 2 schematic diagram is held the A of end 9, link 10 and pull action cylinder 11 tightly to structure chart for activity.
