DETAILED DESCRIPTION

[0033] The specific embodiments of the present invention are described in detail below, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0034] like Figures 1 to 8 As shown, a large-diameter twisted and stranded rope comprises an open mesh belt 2, wherein the open mesh belt 2 is provided with a plurality of strands, and the plurality of strands of the open mesh belt 2 are wound and twisted to form the stranded rope.

[0035] The open mesh belt 2 is directly wound and twisted to form a stranded rope, and the polyester thread 1 is abandoned for bundling. The use of expensive polyester thread 1 is reduced from the raw material level, which greatly reduces the material cost and enhances the price competitiveness of the product in the market. The structure formed by the winding and twisting of the open mesh belt 2 allows the stranded rope to disperse the stress more evenly when subjected to force, improves the overall strength and stability, and provides more reliable support and protection for the cable.

[0036] The present invention also provides a production and processing device for large-diameter twisted and stranded ropes, including a material guiding mechanism 3, a twisting mechanism 4 and a winding mechanism 5. The material guiding mechanism 3 is arranged on the side of the twisting mechanism 4, and is used to feed a plurality of open mesh belts 2 into the twisting mechanism 4. The twisting mechanism 4 is used to wind and twist a plurality of open mesh belts 2 to form a stranded rope. The winding mechanism 5 is arranged on the inner side of the twisting mechanism 4, and is used to wind the stranded rope into a large-diameter rope roll.

[0037] During production, the material guide mechanism 3 transports the multiple strands of open mesh belts 2 to the twisting mechanism 4 in an orderly manner. The twisting mechanism 4 rotates through the rotating shaft 7 and the rotating arm 8 to make the open mesh belts 2 intertwine and twist to form a parallel strand rope. After the parallel strand rope is formed, the winding mechanism 5 winds it into a large-diameter rope coil, and the whole process is automated and coordinated.

[0038] As a further solution of the present invention: the twisting mechanism 4 includes a support frame 6, a rotating shaft 7 and a rotating arm 8, a through hole 9 is provided on the side of the rotating shaft 7, two rotating shafts 7 are provided, and are relatively fixedly arranged on the side of the rotating arm 8, the rotating shaft 7 is rotatably connected with the support frame 6, the winding mechanism 5 includes a rotating frame 10, a winding roller 11 and a winding motor 12, the rotating frame 10 is arranged in the rotating arm 8, and is rotatably connected with the rotating arm 8, the winding roller 11 is horizontally connected to the rotating frame 10, the winding motor 12 is fixedly connected to the rotating frame 10, and the output end of the winding motor 12 is coaxially fixedly connected with the winding roller 11. The twisting mechanism 4 also includes a first roller 13 and a second roller 14, and a plurality of the first rollers 13 and the second rollers 14 are provided, and the first roller 13 is rotatably arranged in the corresponding rotating shaft 7 in a symmetrical state, and the second roller 14 is rotatably arranged on the side of the rotating arm 8 in a symmetrical state. The twisting mechanism 4 further includes a balance arm 15, which is fixedly connected to the rotating arm 8, and the balance arm 15 is symmetrical to the rotating arm 8 with the axis of the rotating shaft 7 as the center line. The twisting mechanism 4 further includes a driving wheel 16, a driven wheel 17, a transmission belt 18 and a twisting motor 19, the driven wheel 17 is coaxially fixedly connected to the rotating shaft 7, the transmission belt 18 is cooperatively arranged between the driving wheel 16 and the driven wheel 17, the twisting motor 19 is fixedly connected to the support frame 6, and the driving wheel 16 is coaxially fixedly connected to the output end of the twisting motor 19.

[0039] The twisting motor 19 drives the driving wheel 16 to rotate, and drives the driven wheel 17 through the transmission belt 18, thereby rotating the rotating shaft 7 and the rotating arm 8 around the support frame 6. The multiple strands of the open mesh belt 2 pass through the through hole 9 of the rotating shaft 7, and bypass the first roller 13 and the second roller 14, and realize winding and twisting during the rotation of the rotating arm 8. The setting of the balance arm 15 ensures the stability of the rotation process. The first roller 13 and the second roller 14 guide the open mesh belt 2 to ensure that each strand of the open mesh belt 2 is evenly stressed during twisting, thereby improving the quality of the stranded rope. The balance arm 15 maintains the balance of the rotating arm 8, reduces vibration and noise during equipment operation, and extends the service life of the equipment.

[0040] As a further solution of the present invention: the winding mechanism 5 also includes an electric telescopic rod 20, a rotating plate 21 and a pressure roller 22. One end of the electric telescopic rod 20 is hinged to the rotating frame 10, the other end of the electric telescopic rod 20 is hinged to the rotating plate 21, one end of the rotating plate 21 is hinged to the rotating frame 10, and the pressure roller 22 is horizontally connected to the other end of the rotating plate 21 in a rotational cooperation. The winding mechanism 5 also includes a slide rail 23, a slider 24, a rope limiting ring 25, a screw rod 26 and an adjustment motor 27. The slide rail 23 is horizontally fixedly arranged on the rotating plate 21, the slider 24 is slidably connected to the slider 24, the rope limiting ring 25 is fixedly connected to the slider 24, the screw rod 26 is rotatably arranged in the slide rail 23, the slider 24 is threadedly connected to the screw rod 26, the adjustment motor 27 is fixedly connected to the slide rail 23, and the output end of the adjustment motor 27 is coaxially fixedly connected to the screw rod 26.

[0041] The winding motor 12 drives the winding roller 11 to rotate to achieve the winding of the stranded rope. The electric telescopic rod 20 controls the rotation of the rotating plate 21 to make the pressure roller 22 contact the stranded rope to ensure the stability of the rope roll. The regulating motor 27 drives the screw 26 to rotate and controls the rope limiting ring 25 to slide back and forth along the slide rail 23 to achieve uniform winding of the stranded rope on the winding roller 11. The cooperation of the rope limiting ring 25 and the screw 26 ensures that the stranded rope is evenly distributed on the winding roller 11, which is convenient for subsequent use and storage.

[0042] As a further solution of the present invention: the material guide mechanism 3 includes a bracket 28, a guide plate 29, a first guide roller 30, a second guide roller 31, a press roller 32 and a guide ring 33. The guide plate 29 is fixedly arranged at one end of the bracket 28, and the bracket 28 is fixedly arranged at the other end of the bracket 28. The first guide roller 30, the second guide roller 31 and the press roller 32 are all rotatably arranged on the bracket 28 in a horizontal state. The first guide roller 30 and the second guide roller 31 are symmetrically distributed, and the press roller 32 is located below the middle of the first guide roller 30 and the second guide roller 31.

The multi-strand open mesh belt 2 passes through the guide holes 34 on the guide plate 29 respectively, bypasses the first guide roller 30, the second guide roller 31 and the press roller 32 in turn, and finally passes through the guide ring 33 to enter the twisting mechanism 4. The arrangement of the guide holes 34, the guide rollers and the pressure rollers 32 allows the multiple strands of the open mesh belts 2 to be arranged in an orderly manner, avoiding problems such as entanglement and knotting during the conveying process, thereby ensuring smooth production.

[0043] The present invention also provides a production process for producing a large-diameter twisted and stranded rope, comprising the following steps:

[0044] S1: Pass several strands of open mesh belt 2 through corresponding guide holes 34 respectively, and pass through the first guide roller 30, the second guide roller and the pressure roller 32 in sequence, and then pass through the guide ring 33;

[0045] S2: Pass the plurality of open mesh belts 2 passing through the guide ring 33 through the through hole 9, and after passing around the first roller 13 and the second roller 14, pass through the rope limiting ring 25 and are fixedly connected to the winding roller 11;
