[0022] Preferably, the composite rope core 11 is woven from nylon multifilament and metal wire. The composite rope core 11 not only inherits the high strength, high toughness and wear resistance of nylon multifilament, but also greatly enhances the overall strength of the composite rope core 11 by adding metal wire, so that it can maintain stable performance and is not prone to breakage or deformation when facing complex working environments such as large tension and high pressure. Further, the metal wire is made of stainless steel or aluminum alloy, which is not easy to rust, and stainless steel and aluminum alloy have excellent corrosion resistance. Even in a humid, high humidity or chemical environment, they can maintain their structural integrity and functionality; at the same time, stainless steel and aluminum alloy metal wires have high strength and hardness, which can provide additional support and reinforcement for the composite rope core 11; and stainless steel and aluminum alloy metal wires also have good ductility and toughness, which can absorb and alleviate shock and vibration to a certain extent.

[0023] Preferably, the flame retardant thermal insulation film 15 is made of flame retardant thermal insulation cotton, which can not only effectively prevent the spread of flames and reduce the risk of fire, but also isolate high temperatures and protect internal components from damage, thereby improving its reliability and stability in high temperature environments and enabling it to perform well in various application scenarios.

[0024] Preferably, the material of the first flame-retardant fiber is flame-retardant polyarylate (LCP), polyester or aramid, and the material of the second flame-retardant fiber is metal fiber. First, flame-retardant polyarylate (LCP), polyester or aramid, with its excellent flame-retardant properties and high temperature resistance, effectively improves the fire resistance of the new steel wire rope cylindrical belt, so that the cylindrical belt can maintain stable performance in a high temperature environment, prevent the spread of flames, and reduce the risk of fire.

[0027] Preferably, the elastic anti-extrusion layer 14 is made of thermoplastic elastomer, which not only improves the anti-extrusion performance and heat resistance of the new steel wire rope cylindrical belt, but also ensures its processability and environmental protection.

[0028] The utility model provides a new type of steel wire rope cylindrical belt, including a cylindrical belt body 1, a fixing piece 2 is arranged at both ends of the cylindrical belt body 1, a connecting piece 3 is arranged at the upper end of the fixing piece 2, and a hook 4 is fixedly welded to the upper end of the connecting piece 3. Firstly, the cylindrical belt body 1 ensures that the cylindrical belt body 1 has extremely high strength and toughness through the laminated structure of the composite rope core 11, the fine steel wire 12 and the aramid fiber composite rope core 13, and can withstand large tensile force without breaking easily, which significantly improves its service life and safety. Secondly, the setting of the elastic anti-extrusion layer 14 effectively reduces the impact of external pressure on the internal structure, enhances the anti-extrusion performance of the cylindrical belt, and enables it to maintain stable performance in various harsh working environments. Furthermore, the use of the flame-retardant heat-insulating film 15 and the flame-retardant sheath 16 greatly improves the flame-retardant performance of the cylindrical belt, effectively prevents the occurrence of fire accidents, and protects the safety of the equipment. The black wear-resistant sheath 17 significantly enhances the wear resistance of the cylindrical belt through the interweaving and winding of 12 strands of the first wear-resistant fiber 171 and the second wear-resistant fiber 172, reduces damage caused by wear, and reduces maintenance costs. At the same time, the black non-reflective property of the black wear-resistant sheath 17 prevents the new steel wire rope cylindrical belt from producing glaring reflections under stage lights, thereby avoiding the reflections affecting the performances of the actors and the viewing experience of the audience.
