DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-3The utility model provides a technical solution: a steel wire rope for a high-rise high-speed elevator, comprising a shell 1, the shell 1 comprising an anti-corrosion layer 101, a wear-resistant layer 102, a sound insulation layer 103, an anti-extrusion layer 104 and a temperature layer 105, the outer side of the shell 1 is provided with an anti-corrosion layer 101, the anti-corrosion layer 101 is usually composed of materials such as galvanizing, and is used to improve the corrosion resistance of the steel wire rope and extend its service life, which is very important for elevators used in harsh environments. A wear-resistant layer 102 is provided on the inner side of the anti-corrosion layer 101, and the anti-corrosion layer 101 is placed on the outermost layer to provide protection for the steel wire rope. This is because the main function of the anti-corrosion layer 101 is to prevent the steel wire rope from being exposed to harsh environments, such as moisture, corrosive gases, etc., so as to extend the service life of the steel wire rope. The wear-resistant layer 102 is located on the inner side of the anti-corrosion layer 101. Its main purpose is to increase the wear resistance of the steel wire rope and reduce friction and wear with other components to extend the life of the entire system. A sound insulation layer 103 is arranged on the inner side of the wear-resistant layer 102. The existence of the sound insulation layer 103 can reduce the impact of the noise generated by the elevator on the surrounding environment. In multi-story buildings or noise-sensitive areas, the sound insulation layer 103 can prevent the elevator noise from interfering with surrounding residents or workplaces, and protect the quietness and comfort of the environment. An anti-extrusion layer 104 is arranged on the inner side of the sound insulation layer 103. The anti-extrusion layer 104 can provide good anti-extrusion ability to prevent the steel wire rope from being flattened or deformed when bearing loads. During the operation of the elevator, the steel wire rope will be subjected to huge tension and pressure, especially when carrying heavy objects or emergency braking. The anti-extrusion layer 104 can effectively disperse these pressures and protect the steel wire rope from being squeezed and damaged. A temperature layer 105 is arranged inside the anti-extrusion layer 104. The temperature layer 105 can have a heat insulation or thermal insulation function to protect the steel wire rope from the influence of high or low temperature environments.

[0018] Furthermore, a stress sensor 6 is provided on the shaft surface of the shell 1. The stress sensor 6 installed on the wire rope can measure the tension change of the wire rope in real time. This sensor can detect any abnormal situation or potential fault by continuously monitoring the stress of the wire rope. A pressure-resistant filling layer 3 is provided inside the shell 1. The pressure-resistant filling layer 3 can enhance the structural stability of the wire rope. By filling the gap, the filling layer can keep each steel wire of the wire rope in a relatively fixed position and reduce the relative movement between the steel wires, which helps to maintain the overall shape and stability of the wire rope and reduce shock and vibration during the operation of the elevator. The second reinforcing strand 4 is axially arranged along the inner side of the shell 1, and the second reinforcing strand 4 is located inside the pressure-resistant filling layer 3. The outer surface of the second reinforcing strand 4 is set as a thick steel cable 41, and thin steel cables 42 are arranged between the several groups of thick steel cables 41. Several groups of first reinforcing strands 2 are provided on the inner side of the shell 1, and the first reinforcing strands 2 are radially arranged along the inner side of the shell 1. The inner side of the shell 1 is installed with a second reinforcing strand 4. The addition of several groups of reinforcing strands can significantly increase the strength of the wire rope. The wire rope needs to bear the weight of the elevator itself as well as additional loads, such as the weight of passengers and cargo. Strengthening strands can increase the tensile strength of the wire rope, allowing it to withstand greater forces and loads, improving safety and thus providing greater security.

[0019] Furthermore, a central strand 5 is provided at the center of the outer shell 1, and a polymer filling layer 51 is provided on the outer side of the central strand 5. The polymer filling layer 51 is mainly made of polymer materials, such as polyethylene, polyurethane, etc. These materials have good elasticity and impact resistance. The polymer filling layer 51 can absorb and disperse the impact and vibration generated during the operation, thereby reducing the vibration and noise during the operation of the elevator, providing a smoother and more comfortable riding experience, and at the same time enabling the steel wire rope to have a certain flexibility and bending performance, so as to better adapt to the curves or curved tracks that may exist in the elevator system. A third reinforcement strand 52 is provided on the inner side of the polymer filling layer 51, and a main core strand 53 is provided on the inner side of the third reinforcement strand 52.

[0020] When in use, the anti-corrosion layer 101 and the wear-resistant layer 102 are used to provide protection for the steel wire rope, so that the service life of the steel wire rope can be extended even in humid environments. The sound insulation layer 103 reduces the impact of the noise generated by the elevator on the surrounding environment. The anti-extrusion layer 104 and the pressure-resistant filling layer 3 can enhance the structural stability of the steel wire rope. The temperature layer 105 is insulated to extend the service life of the steel wire rope. The polymer filling layer 51 reduces the vibration and noise during the operation of the elevator. Then, multiple groups of reinforcing strands are used to increase the strength of the steel wire rope to improve safety. Finally, the stress sensor 6 can measure the tension change of the steel wire rope in real time to detect the condition of the steel wire rope.

[0021] In this embodiment, a steel wire rope for a high-rise high-speed elevator, in the above-mentioned components, its own structural features and working principles all adopt the existing technology, which will not be described in detail here.
