Description

Technical Field

[0001] This utility model relates to the field of rope technology, and in particular to a safety rope used in fire rescue. Background Technology

[0002] During use, fire safety ropes are typically made of synthetic fiber materials. This material can effectively withstand high temperatures, ensuring that the rope's performance is not affected in high-temperature environments such as fire scenes. However, synthetic fiber materials have relatively low surface friction. When people need to quickly use fire safety ropes for escape or rescue, without suitable gloves or cloths to increase the friction between the rope and their palms, the rope may slip due to insufficient friction, thus affecting the safety of escape or rescue. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a safety rope with high friction for use in fire rescue. Furthermore, when used in conjunction with the safety buckle in this solution, it can improve the stability of the safety buckle connection.

[0004] According to one aspect of this utility model, a safety rope for fire rescue is provided.

[0005] The safety rope consists of an aramid fiber layer, a nylon fiber layer, and a core, from the outside in. The aramid fiber layer is a high-temperature resistant layer, and the surface of the nylon fiber layer is decorated with a highly saturated color. The core is made of nylon 66. The outermost diameter of the safety rope is ≤11.5mm, and its strength is ≥43.5kN.

[0006] In the above technical solution, the aramid fiber layer (outermost layer): As a high-temperature resistant layer, aramid fiber has excellent heat resistance and flame retardancy, remaining stable in high-temperature environments and preventing damage to the internal structure of the rope from flames and heat, providing necessary protection for firefighters. The nylon fiber layer (middle layer): Its surface is finished with highly saturated colors, which not only improves the visibility of the rope, facilitating rapid identification and location at the rescue site, but may also serve as a warning. Nylon fiber itself has good strength and abrasion resistance, providing additional mechanical support to the rope. The core (Nylon 66): Nylon 66 is a high-strength, high-toughness engineering plastic with excellent mechanical properties and heat resistance. As the core, it provides the main load-bearing capacity of the entire rope, ensuring that the rope can withstand significant tension during rescue operations. Diameter (≤11.5mm): The smaller diameter makes the rope lighter, easier to carry and handle, and allows for easier passage through narrow spaces or high-altitude operations during rescue operations. Strength (≥43.5kN): High strength ensures that the rope can be used safely and reliably in various complex and dangerous rescue scenarios, and can withstand the weight of firefighters, equipment, and other external forces that may be encountered.

[0007] In some embodiments, the surface color of the nylon fiber layer is complementary to the surface color of the aramid fiber layer and the rope core.

[0008] In the aforementioned technical solution, the use of complementary colors allows firefighters to more intuitively assess the stress and damage level of the safety rope. For example, when a portion of the rope is subjected to significant tension or shows wear, the color change becomes more pronounced, helping firefighters to promptly identify potential safety hazards and take appropriate measures. Furthermore, different sections or functional areas of the safety rope can be marked. For instance, using complementary colors at regular intervals for segmented markings allows firefighters to quickly determine the rope's length and remaining length during rescue operations, enabling them to plan rescue actions effectively.

[0009] In some embodiments, the safety rope consists of an aramid fiber layer, a nylon fiber layer, and a rope core, from the outside to the inside.

[0010] The outer surface of the aramid fiber layer is wrapped with a first granular adhesive layer; a TPU flame-retardant film is filled between the granular adhesive layer and the aramid fiber layer.

[0011] In the above technical solution, the outermost layer is an aramid fiber layer. The aramid fiber layer possesses properties such as high temperature resistance, flame retardancy, and chemical corrosion resistance, providing protection for the safety rope in harsh environments such as fire rescue, resisting the erosion of flames, high-temperature smoke, and chemicals, ensuring the stability and safety of the rope during use. The outer surface of the aramid fiber layer is wrapped with a first granular adhesive layer, which increases the surface friction of the rope, making it more secure for firefighters to grip and reducing accidents caused by slippage. Between the granular adhesive layer and the aramid fiber layer is a TPU flame-retardant film. TPU material has flame-retardant properties, further enhancing the fire resistance of the safety rope, while also acting as heat insulation, reducing the rate of heat transfer to the interior of the rope, and protecting the inner structure from high-temperature damage. The inner layer is a nylon fiber layer. Nylon fibers have high strength and good toughness, capable of withstanding significant tensile force, providing mechanical support for the safety rope, ensuring it can support the weight of firefighters and rescued personnel during rescue operations, and guaranteeing the smooth progress of the rescue operation. The innermost core is the core load-bearing part of the safety rope. Its material and structural design play a decisive role in the rope's strength and stability. It is usually made of high-strength, high-toughness fiber materials and processed by special technology to meet the requirements of high strength and high reliability of ropes in fire rescue.

[0017] Example 1

[0018] Please see Figure 1A safety rope for fire rescue applications is described, comprising, from the outside in, an aramid fiber layer 11, a nylon fiber layer 12, and a core 13. The aramid fiber layer 11 is a high-temperature resistant layer, and the nylon fiber layer 12 has a highly saturated color on its surface. The core 13 is made of nylon 66. The outermost diameter of the safety rope is ≤11.5mm, and its strength is ≥43.5kN. The aramid fiber layer (outermost layer) serves as a high-temperature resistant layer, possessing excellent heat resistance and flame retardancy. It remains stable in high-temperature environments, preventing damage to the internal structure of the rope from flames and heat, and providing necessary protection for firefighters. The nylon fiber layer (middle layer) has a highly saturated color on its surface, which not only improves the visibility of the rope, facilitating rapid identification and location at the rescue site, but may also serve as a warning. Nylon fibers themselves have good strength and abrasion resistance, providing additional mechanical support to the rope. Rope Core (Nylon 66): Nylon 66 is a high-strength, high-toughness engineering plastic with excellent mechanical properties and heat resistance. As the rope core, it provides the main load-bearing capacity of the entire rope, ensuring that the rope can withstand significant tensile forces during rescue operations. Diameter (≤11.5mm): The smaller diameter makes the rope lighter, easier to carry and handle, and allows for easier passage through confined spaces or high-altitude operations during rescue operations. Strength (≥43.5kN): High strength ensures the rope can be used safely and reliably in various complex and dangerous rescue scenarios, capable of withstanding the weight of firefighters, equipment, and other external forces that may be encountered.

[0019] In this embodiment, the surface color of the nylon fiber layer 12 is complementary to the colors of the aramid fiber layer 11 and the rope core surface 13. This complementary color design allows firefighters to more intuitively assess the stress and damage level of the safety rope. For example, when a portion of the rope is subjected to significant tension or shows wear, the color change becomes more pronounced, helping firefighters to promptly identify potential safety hazards and take appropriate measures. Furthermore, different parts or functional areas of the safety rope can be marked. For instance, using complementary colors at regular intervals for segmented markings facilitates firefighters in quickly determining the rope's length and remaining length during rescue operations, enabling them to plan rescue actions effectively.

[0022] The outer surface of the aramid fiber layer 13 is wrapped with a first granular adhesive layer 14; a TPU flame-retardant film (not shown in the figure) is filled between the granular adhesive layer 14 and the aramid fiber layer 13; the granular adhesive layer can be a chicken skin adhesive layer or a layered structure with granules on the surface made of rubber or polyurethane.

[0023] In this embodiment, the outermost layer is an aramid fiber layer. The aramid fiber layer possesses properties such as high temperature resistance, flame retardancy, and chemical corrosion resistance, providing protection for the safety rope in harsh environments such as fire rescue, resisting the erosion of flames, high-temperature smoke, and chemicals, ensuring the stability and safety of the rope during use. The outer surface of the aramid fiber layer is wrapped with a first granular adhesive layer, which increases the surface friction of the rope, making it more secure for firefighters to grip and reducing accidents caused by slippage.
