Description

Technical Field

[0001] The utility model relates to the technical field of flame-retardant ropes, in particular to a flame-retardant filling rope. Background Art

[0002] The cable has the properties of tensile resistance, impact resistance, wear resistance, and flexibility. Most of the current cables are woven from flammable materials and have poor flame retardant effects. After searching, it was found that the Chinese utility model patent with the authorization publication number CN217869690U discloses a rope with flame retardant properties. It can be seen from its specification that by providing a flame retardant leather strip, it can be used to protect the rope by wrapping multiple groups of flame retardant leather strips around the rope, and the multiple groups of flame retardant leather strips are abutted against each other, so as to make it have a flame retardant effect.

[0003] However, the above-mentioned rope has the following problems: (1) The rope itself does not have a flame retardant effect. Instead, a flame retardant leather strip must be installed on the rope and the rope must be surrounded by the flame retardant leather strip to achieve a flame retardant effect; (2) When a certain section of the rope is heated, the heat cannot be transferred quickly, which will cause the local temperature to be too high, making it easy to burn. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a flame retardant filling rope to solve the problems mentioned in the above background technology.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] A flame retardant filling rope comprises a rope body and a plurality of flame retardant sleeves clamped on the rope body, the rope body comprises a rope core, a plurality of first rope strands and heat-conducting rope strands braided on the outer periphery of the rope core, the first rope strands and the heat-conducting rope strands are alternately arranged, the outer peripheries of the first rope strands and the heat-conducting rope strands are coated with a heat insulation layer, a flame retardant is filled between the heat insulation layer and the rope core, and the outer periphery of the heat insulation layer is coated with a flame retardant and wear-resistant layer; the flame retardant sleeve is filled with a dry powder fire extinguishing agent.

[0007] Preferably, the rope core is woven from a plurality of second rope strands, and the first rope strands and the second rope strands are both woven from aramid fibers or polyarylate fibers.

[0008] Preferably, the thermally conductive strands are woven from metal fibers.

[0009] Preferably, the flame retardant is aluminum hydroxide powder.

[0010] Preferably, the flame retardant sleeve comprises an annular sleeve, a storage bag arranged in the sleeve, and an extension plate connected to one side of the sleeve.

[0011] Preferably, a plurality of bayonet holes are provided on the flame retardant and wear resistant layer, and buckles cooperating with the bayonet holes are connected to the extension plate, and the buckles are snapped into the bayonet holes.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] (1) The first strand and the heat-conducting strand are arranged on the periphery of the rope core. The heat-conducting strand can quickly transfer heat to prevent the local temperature from being too high, thereby improving the fire resistance of the strand.

[0014] (2) Flame retardants are filled between the heat insulation layer and the flame retardant and wear-resistant layer to slow down the burning speed. Dry fire extinguishing agents are filled in the flame retardant sleeve, which can form an isolation layer that hinders combustion and further slows down the burning speed when covered on the solid combustion material, and even achieves the purpose of extinguishing the fire.

DETAILED DESCRIPTION

[0019] 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.

[0020] See also Figure 1 and Figure 2 A flame retardant filling rope comprises a rope body and a plurality of flame retardant sleeves 7 clamped on the rope body. The rope body comprises a rope core 1, a plurality of first rope strands 2 and heat-conducting rope strands 3 braided on the outer periphery of the rope core, the first rope strands 2 and the heat-conducting rope strands 3 are alternately arranged, the rope core 1 is woven from a plurality of second rope strands 9, the first rope strands 2 and the second rope strands 9 are both woven from aramid fibers or polyarylate fibers, and have high strength and flame retardant properties; the heat-conducting rope strands 3 are woven from metal fibers, which can quickly transfer temperature and prevent local temperature from being too high.

[0021] The first strand 2 and the heat-conducting strand 3 are coated with a heat-insulating layer 4, a flame retardant 5 is filled between the heat-insulating layer 4 and the rope core 1, and a flame-retardant and wear-resistant layer 6 is coated on the periphery of the heat-insulating layer 4. The flame-retardant and wear-resistant layer 6 can be made of chloroprene rubber. The flame retardant 5 is aluminum hydroxide powder, which can be decomposed into aluminum oxide and water at high temperature. The water vapor absorbs a large amount of heat. At the same time, the ceramic layer formed by aluminum oxide can isolate the material and the combustion process, further slow down the combustion speed, and improve the fire prevention effect.

[0022] like Figure 3 As shown, the flame retardant sleeve 7 includes an annular sleeve 701, a storage bag arranged in the sleeve, and an extension plate 702 connected to one side of the sleeve. The dry powder fire extinguishing agent 8 is installed in the storage bag, and the inner wall and outer wall of the sleeve 701 are provided with a plurality of through holes 703. The flame retardant and wear-resistant layer 6 is provided with a plurality of bayonet holes 10, and the extension plate 702 is connected with a buckle 704 that cooperates with the bayonet hole, and the flame retardant sleeve is connected to the rope body through the cooperation between the buckle 704 and the bayonet hole 10. When a fire occurs, the storage bag is burned or broken, and the dry powder fire extinguishing agent in the storage bag is sprayed out from the through hole 703. Among them, the dry powder fire extinguishing agent is fine particles made by mixing and grinding a fire extinguishing base material (such as baking soda, ammonium carbonate, ammonium salt of phosphate, etc.) and an appropriate amount of lubricant (magnesium stearate, mica powder, talcum powder, etc.) and a small amount of moisture-proof agent (silica gel). The powder has a dense concentration and fine particles. It can form an isolation layer that hinders combustion when covered on solid combustion materials. At the same time, it precipitates non-combustible gas to reduce the oxygen concentration in the air, thereby slowing down the combustion rate and even extinguishing the flame.

[0023] In actual use, the flame retardant sleeve is optional and can be installed or not installed according to needs. When the flame retardant sleeve is installed, an appropriate number of flame retardant sleeves can also be installed according to needs.
