The main traction wheel 4.42 and the auxiliary traction wheel 4.43 are arranged on the cradle 4.4 through bearings, the main traction speed reducing motor 4.44 is arranged on the cradle 4.4 and used for driving the main traction wheel 4.42 to rotate, and the main traction speed reducing motor 4.44 directly drives the main traction wheel 4.42 and provides traction force for twisting steel wires together with the auxiliary traction wheel 4.43. The inner over-twisting wheel 4.46 is arranged on the inner over-twisting shaft 4.45, two ends of the inner over-twisting shaft 4.45 are arranged on the cradle 4.4 through bearing seats, and the inner over-twisting motor 4.47 is used for driving the inner over-twisting shaft 4.45 and the inner over-twisting wheel 4.46 to rotate; the axis of the inner over-twisted shaft 4.45 is tangent to the excircle of the auxiliary traction wheel 4.43; the inner over-twist motor 4.47 drives the inner over-twist shaft 4.45 and the inner over-twist wheel 4.46 through a synchronous belt, so that the steel wire rope twisted into a rope obtains good tightness quality. The invention controls the speed of the main traction speed reducing motor 4.44 and the main motor 4.6, achieves the effect of stepless variable lay length, can produce the steel wire rope with the desired lay length by simply setting a program, does not need to replace a lay length gear to change the transmission ratio, and has simple operation.

In the technical scheme, the wire arranging wheel 4.48, the wire arranging guide rod 4.49, the wire arranging lead screw 4.410 and the wire arranging speed reducing motor 4.411 form a wire arranging assembly, the first jacking 4.412, the second jacking 4.413 and the jacking speed reducing motor 4.414 form a wire collecting assembly, the first jacking 4.412, the second jacking 4.413 and the jacking speed reducing motor are fixed at corresponding positions on the cradle, the axes of the first jacking 4.412, the second jacking 4.413 and the jacking speed reducing motor are ensured to be parallel, and the starting and stopping positions of the stroke are the same. The winding displacement speed reducing motor 4.411 is used for driving a winding displacement screw shaft 4.410 to drive the winding displacement wheels 4.48 to reciprocate, and the steel wire ropes are uniformly arranged on the wire take-up spool 4.416; the first tightening unit 4.412 and the second tightening unit 4.413 together tighten the wire rope take-up spool 4.416, the tightening reduction motor 4.414 drives the second tightening unit 4.413 to drive the wire take-up spool 4.416 to take up the wire rope, and the straightener 4.415 is used for extruding the wire rope to be straight. The wire arrangement is driven by a servo motor and is matched with the 4.414 speed of the jacking speed reduction motor, different wire arrangement distances are conveniently adjusted, the reversing speed is high, and dense arrangement of the steel wire ropes on the spool can be completed; the jacking speed reducing motor 4.414 adopts a torque mode, so that the take-up tightness can be ensured.

When the steel wires are twisted into a rope, a plurality of steel wires pass through the wire collecting disc 2.1 and the wire collecting eye die 2.2 to be combined into a strand, then pass through the middle holes of the over-twist shaft 3.21, the over-twist wheel 3.22 and the second rotary wheel shaft 4.3, pass through the second large wire passing wheel 4.33, the second small wire passing wheel 4.32, the middle hole of the first rotary wheel shaft 4.2, pass through the first small wire passing wheel 4.22 and the first large wire passing wheel 4.2.3 in sequence, enter the cradle 4.4, are wound back and forth between the main traction wheel 4.42 and the auxiliary traction wheel 4.43 and then enter the inner over-twist shaft 4.45, the inner over-twist wheel 4.46, the straightener 4.415 and the wire arranging wheel 4.48 in sequence, and finally are wound on the wire collecting I-shaped wheel 4.416 until the wire collecting I-shaped wheel 4.416 is fully wound, and the production of the steel wire rope with one wheel is completed.
