The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
A processing technology of an anti-rotation steel wire rope is characterized in that: the method comprises the following processing steps:
s1, wire drawing: drawing a raw material steel wire by using a drawing machine;
s2, stranding: putting the steel wire drawn in the S1 on a stranding machine for stranding, and stranding into a central strand middle strand 5, a central strand side strand 3 and a rope side strand 4;
s3, manufacturing a central strand 1: putting the center strand middle strand 5 and the center strand side strand 3 which are manufactured in the S2 on a rope forming machine to form a rope, and synthesizing a center strand 1;
s4, strand winding: winding the center strand 1 produced in S3 on a reel 6;
s5, rope forming: connecting the reel 6 in S4 to the rope feeding side of the rope forming machine to ensure that the axial direction of the reel 6 is perpendicular to the rope feeding direction, putting the cord side strand 4 made in S2 into the rope forming machine, driving the reel 6 to rotate around the axial direction thereof for rope feeding, wherein the reel 6 can be driven by external force such as a motor to conveniently feed the rope around the axial direction thereof, or driving the reel 6 to rotate passively by pulling the center strand 1 through friction force, simultaneously driving the reel 6 to turn in a vertical plane perpendicular to the axial direction thereof by the motor, and the turning direction is consistent with the twisting direction of the center strand 1, namely, the reel 6 is turned along the twisting direction of the center strand 1, and the cord side strand 4 in the rope forming machine is twisted in rotation outside the center strand 1 in the opposite direction to the twisting direction of the center strand 1, since the center strand 1 is driven by the reel to rotate along the twisting direction thereof, when the cord side strand 4 rotates in the opposite direction thereto, the force driving the center strand 1 to loosen is offset by the force rotating in the direction thereof, thereby, the lay length of the central strand 1 is ensured to be unchanged, and the rotating forces of the central strand 1 and the steel wire rope 2 can be just offset mutually after rope formation.
Referring to fig. 2 and 3, the spinning reel 6 is shown schematically. The reel 6 rotates in its axial direction, causing the center strand 1 to advance into the rope machine, while the reel 6 is turned in the vertical direction, thereby driving the center strand 1 to rotate about its lay direction.
In order to prevent the central strand side strand 3 from rotating too slowly, the central strand side strand 3 still can drive the central strand 1 to scatter, so that the quality of the steel wire rope 2 is influenced, or because the central strand side strand 3 rotates too fast, the central strand side strand 3 is influenced by the rotation of the central strand 1 to lay a pitch, so that the anti-rotation performance of the steel wire rope is reduced, in the step S5, the rotating speed of the central strand side strand 3 is 3-10 times of the rotating speed of the central strand 1, and the rope forming quality is ensured.
In this embodiment, the number of strands of 3 strand on the edge of the central strand is 6 strands, the number of strands of 4 strand on the edge of the rope is 8 strands, the softness and the anti-rotation performance applicability of 8 strands of ropes are strong, and in addition, for ensuring that the diameter of 1 strand of the central strand is 44.5% -54.5% of the diameter of the steel wire rope, 8 strands of ropes are the most reasonable number of strands. In this embodiment, the diameter of the center strand 1 is 49.5% of the diameter of the steel wire rope 2, so as to ensure that the internal and external rotating forces are substantially equal and offset.
In the embodiment, the lay length of the central strand 1 is properly increased to be 7-9 times, preferably 8 times of the diameter of the central strand 1, so that the anti-rotation property of the central strand is improved; meanwhile, the lay length of the steel wire rope 2 is properly increased to be 6.8-7.3 times, preferably 7 times of the diameter of the steel wire rope 2, so that the softness is guaranteed, and no gap is left on the surface of the steel wire rope 2 to meet the use requirement. The lay length of the steel wire rope 2 is larger than that of the prior art, and the diameter of the central strand is also increased compared with that of the prior art, so that the twisting force of the outer layer of the rope combination is reduced, and the anti-rotation performance of the rope combination is ensured.
When no special requirement exists, the surface of the finished steel wire rope 2 needs to be uniformly coated with antirust lubricating oil in the manufacturing process so as to ensure the surface lubrication, and the problems of contusion, rusting and the like are not easy to occur.
