[0028] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] The double-compacted spiral plastic-filled anti-rotation steel wire rope provided by the present invention is divided into an inner layer rope compaction type and an outer layer rope compaction type. Figures 1-4 As shown, it includes an inner layer rope 7, which is twisted from a number of unit strands. The space between each unit strand in the inner layer rope 7 is filled with a solid polymer. The solid polymer can be any one of polypropylene (PP), ethylene / α-olefin copolymer elastomer (POE), or low-pressure high-density polyethylene (PE). During filling, the solid polymer overflows to the periphery of the inner layer rope 7 to form a plastic coating layer 5. The surface of the plastic coating layer 5 is prefabricated with a number of continuous spiral grooves evenly distributed along the axial direction. The prefabrication method is to use a spiral plastic coating mold to spirally coat the inner layer rope 7. The specific operation method is described in the manufacturing method below. The cross-section of the prefabricated plastic coating layer 5 is star-shaped. The outer layer strands are evenly twisted around the outer layer 5 with the same number of spiral grooves as the spiral grooves. The outer layer strands are tightly twisted and embedded in the corresponding spiral grooves to form the outer layer rope 6. The twist pitch of the outer layer rope 6 matches the pitch of the spiral groove, and the bottom diameter of the spiral groove matches the strand diameter of the inner and outer layers of the spiral groove. Each unit strand and outer strand is twisted from a number of galvanized steel wires. The number of steel wires in each unit strand and outer strand is no less than 7, and the strands are manufactured using a process of first plating and then drawing. For example, if 7 steel wires are used, the arrangement structure can be a K(1+6) arrangement with 1 wire in the center and 6 wires on the periphery; similarly, if 19 steel wires are used, the arrangement structure can be a K(1+9+9) arrangement with 1 wire in the center, 9 wires in the inner layer, and 9 wires in the outer layer, or an arrangement structure using other quantity structures. The present invention does not limit the specific number of steel wires in the unit strands and outer strands. The diameter of the unit strand is determined by the diameter of the selected steel wire, and the unit strands can be prefabricated into different diameter specifications according to usage needs.

[0030] Depending on the type of twisted wire rope, the inner rope 7 or the outer rope 6 is selected to be forged after twisting, for example, Figure 1 and Figure 3 In the case of the compacted inner rope type shown, the inner rope 7 needs to be forged during manufacturing, while the outer rope 6 does not need to be forged; Figure 2 and Figure 4The outer layer rope compaction type shown, the outer layer rope 6 needs to be forged during manufacturing, and the inner layer rope 7 does not need to be forged. Thus, it can be understood that the double compaction structure in the application refers to the compaction of the unit strand and the outer layer strand during production, and the forging process treatment of the outer layer or the inner layer of the two structures is selected during the production of the steel wire rope, so as to achieve the effect of the double compaction structure.

[0031] The inner layer rope 7 described above is twisted from a plurality of unit strands, and a steel wire rope structure is provided, specifically comprising a center strand 1, the center strand 1 being 1 strand, a plurality of inner layer strands 2 being uniformly twisted along the circumferential direction of the outer side of the center strand 1, the inner layer strands 2 being 6 strands, a plurality of secondary outer layer large strands 4 and secondary outer layer small strands 3 being uniformly twisted along the circumferential direction of the outer side of the inner layer strands 2, the secondary outer layer large strands 4 and the secondary outer layer small strands 3 being 6 strands, the secondary outer layer large strands 4 and the secondary outer layer small strands 3 being alternately arranged in the same layer, the secondary outer layer large strands 4 and the secondary outer layer small strands 3 selecting unit strands of different diameter specifications, the secondary outer layer large strands 4 selecting unit strands of larger diameter specifications, and the secondary outer layer small strands 3 selecting unit strands of smaller diameter specifications. At the same time, the outer layer strands in the outer layer rope 6 are 16 strands.

[0032] The application also provides a manufacturing method of the double-compaction spiral plastic-filled anti-rotation steel wire rope, which is specifically performed according to the following steps:

[0033] Step 1: a plurality of steel wires are grouped and compacted by a stranding machine and a compaction tool to be twisted into unit strands and outer layer strands;

[0034] Step 2: a plurality of unit strands are twisted, if it is an inner layer rope compaction type, the forged inner layer rope 7 is forged on line by using a forging device, if it is an outer layer rope compaction type, the inner layer rope 7 does not need to be forged, and the inner layer rope 7 is obtained;

[0035] Step 3: the inner layer rope 7 is spiral plasticized by using a spiral plasticizing machine head in cooperation with an extruding machine, solid polymers are filled into the inner layer rope 7, and overflow to the periphery of the inner layer rope 7 to form a plasticized layer 5 with spiral grooves;

[0036] Among them, as Figure 6 and Figure 7As shown, the specific structure of the spiral plastic coating machine head includes a chain wheel, which is driven to rotate by a servo motor through a chain. The chain wheel is sleeved with the outer ring of a bearing at the center, and the inner ring of the bearing is fixedly connected with a mold sleeve 8. The bearing can be a deep groove ball bearing, which fixes the bearing mold sleeve 8. The inner cavity of the mold sleeve 8 is a smooth cylindrical surface. The chain wheel is fixedly connected with a rotating mold sleeve 9 at the outer side in contact with the bearing. The inner cavity of the rotating mold sleeve 9 is coaxial with the inner cavity of the mold sleeve 8. The inner cavity of the rotating mold sleeve 9 is engraved with a spiral groove star-shaped inner cavity at the end away from the mold sleeve 8. The inner layer rope 7 passes through the inner cavities of the mold sleeve 8 and the rotating mold sleeve 9 in the axial direction. The molten solid polymer fills into the inner layer rope 7 through the injection channel and overflows to coat the surface thereof. At the same time, the inner layer rope 7 is pulled along the axis. The pulling speed of the plastic coating axis is matched with the radial rotating speed of the rotating mold sleeve 9. When the inner layer rope 7 passes through the spiral groove star-shaped inner cavity of the rotating mold sleeve 9, the spiral groove is formed on the surface of the inner layer rope 7.

[0037] Step 4: The corresponding number of outer strands of the spiral groove are twisted in the circumferential direction of the groove body, so that each outer strand is uniformly embedded in the corresponding spiral groove groove body. If it is an outer rope compaction type, the forged device is used for online forging process treatment of the twisted outer rope 6. If it is an inner rope compaction type, it is not necessary to forge, but to twist the outer rope 6 directly. Finally, a double-compaction spiral plastic-filled anti-rotation steel wire rope is obtained.
