[0032] Please refer to Figures 1-5 The utility model provides a steel wire rope with high tensile strength, in use, the cross section of the metal wire rope core 10 is regular hexagon, the metal wire rope core 10 is twisted by the steel wire of same or similar material with the outer layer steel wire 17, thereby has higher strength and rigidity, can provide powerful support for the outer layer steel wire 17, effectively improves the overall tensile strength and extrusion resistance of the steel wire rope, when bearing larger tension, the metal wire rope core 10 can share a part of tension, makes the stress of the steel wire rope more uniform, the metal wire rope core 10 can guarantee the structural integrity and performance stability of the steel wire rope under long-term high load operation, greatly prolongs the service life of the steel wire rope, improves the tensile strength of the steel wire rope, improves the safety and reliability of the operation of the use equipment.
[0033] The filling layer 11 is arranged between the fiber rope core 12 and the metal wire rope core 10, and the filling layer 11 is composed of non-woven fabric and rubber particles, which is beneficial to increasing the friction while avoiding wear between the fiber rope core 12 and the metal wire rope core 10, so that the connection structure of the metal wire rope core 10 and the fiber rope core 12 is stable, and the tensile strength is improved.
[0034] The fiber rope core 12 is made of natural fiber or synthetic fiber, so that the fiber rope core 12 has good flexibility and moisture absorption, can play a buffering role in the steel wire rope, reduce the friction and wear between the steel wires, and can store a certain amount of lubricant, which is beneficial to the lubrication and maintenance of the steel wire rope.
[0035] The outer side of the fiber rope core 12 is provided with a temperature insulation layer 13, which is made of heat insulation material and can effectively protect the fiber rope core 12 and the material in the filling layer 11 from denaturation caused by high temperature. Meanwhile, the temperature insulation layer 13 is provided with equidistantly distributed air holes 14, which are circular in shape. The air holes 14 are beneficial to the communication between the fiber rope core 12 inside the temperature insulation layer 13 and the outside, facilitating the addition of lubricant and moisture absorption. Meanwhile, the air holes 14 are beneficial to the increase of the friction between the fiber rope core 12 and the inner layer steel wire 15, thereby facilitating the increase of the flexibility and stability of the steel wire rope and greatly prolonging the service life of the steel wire rope and improving the tensile strength.
[0036] The outer side of the air hole 14 is the inner layer steel wire 15. The inner layer steel wire 15 and the outer layer steel wire 17 are provided with a separation layer 16 therebetween. The separation layer 16 is in a mesh structure and is made of rubber material, which is used to increase the friction between the inner layer steel wire 15 and the outer layer steel wire 17. The diameter of the inner layer steel wire 15 is 0.5-0.7 times the diameter of the outer layer steel wire 17. The inner layer steel wire 15 can increase the number of layers of the strand rope without increasing too much weight and rigidity, improve the flexibility of the strand rope, make it easier to bend, and adapt to the winding requirements of the pulley and other equipment. The outer layer steel wire 17 mainly bears larger tension. Due to the larger cross-sectional area of the outer layer steel wire 17, it can bear higher tensile stress, thereby ensuring the tensile strength of the whole steel wire rope. Through the cooperation of the inner layer steel wire 15 and the outer layer steel wire 17 with different diameters, the steel wire rope can have high strength while maintaining a certain flexibility, which is convenient for operation and installation in actual use.
[0037] The lay length refers to the axial distance that the strand rope or the steel wire rises around the rope core in one revolution. The lay length has a certain proportional relationship with the diameter of the steel wire rope. The common lay length range is 6-8 times the diameter of the steel wire rope. If the lay length is too small, the steel wire rope will become too rigid, and when it is bent around the pulley or the drum, a larger bending stress will be generated, which is easy to cause fatigue damage of the steel wire rope and reduce its service life. When the lay length is too large, the structural stability of the steel wire rope will be poor, and the strand ropes will be easy to loosen. When the force is transmitted, it will not be uniform, which will reduce the tensile strength and overall performance of the steel wire rope. Therefore, the lay length range of the inner layer steel wire 15 and the outer layer steel wire 17 is 6-8 times the diameter of the inner layer steel wire 15 and the outer layer steel wire 17, respectively.
[0038] The lay directions of the inner layer steel wire 15 and the outer layer steel wire 17 are opposite. When one end of the steel wire rope is subjected to tension, if the lay directions of the strand ropes are the same, the whole steel wire rope will produce a large rotation, which not only affects its use effect, but also may cause damage to the equipment connected thereto. The strand rope structure with opposite lay directions of the inner layer steel wire 15 and the outer layer steel wire 17 can offset the rotation trend of the strand ropes when subjected to force, so that the steel wire rope can remain relatively stable and improve the working safety and reliability of the inner layer steel wire 15 and the outer layer steel wire 17.
[0039] While the embodiments of the present application have been illustrated and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the spirit and scope of the application, which is defined by the appended claims and their equivalents.
