Description

A kind of escaping rope

Technical field

The utility model belongs to Knitted rope technical field, more particularly, to a kind of escaping rope.

Background technique

Escaping rope is one kind important daily necessities and security against fire, fire rescue, building is escaped, mining industry is escaped Commonly using escaping rope is arrived in raw essential product, especially fire-fighting equipment, once fire or accident occurs, fire fighter is needed It to use and land to escaping rope, the land that is transported to of personnel safety can quickly be built from high level using escaping rope It builds and lands on object, frequency of use of the escaping rope in scene of fire is very high, but escaping rope is typically all using in high temperature Working environment, so having stronger requirement for the heat-resisting ability of rope, the shell of rope will not easily burn, and guarantee The requirement of escaping rope, it is desirable that quality, ductility, intensity and the security performance of rope be all very high, at present on the market Rope is not able to satisfy the requirement of escaping rope performance, it is therefore necessary to be improved.

Utility model content

The purpose of this utility model is in view of the deficiency of the prior art, to provide a kind of escaping rope and its preparation side Method, it has the characteristics of fugitive anticreep when giving birth to sliding, safer wear-resisting and cut resistant and long service life.

To achieve the goals above, the technical scheme adopted by the utility model is a kind of escaping rope, including rope Pi Hetao It is located at the intracutaneous wire rope core of rope, the wire rope core is twisted by 7 groups of main core groups, and the main core group is twisted by 7 one metal wires, institute Stating rope skin includes inner rope skin and outer rope skin, and the inner rope skin is made of the interlaced braiding of 12 first strands, the outer rope skin It is made of the interlaced braiding of 12 second strands.

Further, the wire uses stainless steel wire.

Further, first strands and the second strands are made of at least 7 aramid fibers.

A kind of preparation method of escaping rope, the preparation method include:

First by 7 one metal wires by strander twist at main core group, then again by 7 main core groups by strander twisting at Wire rope core changes double 12 strands of braiders and carries out the rope skin that inside and outside dual braiding composition is set in outside wire rope core followed by 24 strands of braiders.

After adopting the above structure, the utility model is compared to the prior art advantageously: the rope of the utility model Core by 7 one metal wires twist at main core group, then take 7 groups main core group twist at wire rope core, ratio in this way directlys adopt 49 gold Belong to that silk twisting is more preferable at wire rope core its toughness, intensity is higher, the service life is longer, even if using such structure wherein metal Silk, which has broken, will not cause whole one metal wire to be detached from wire rope core, will not influence whole use, and the connection gap between wire It is smaller to protrude the too long service life poked rope figure for shadow-play and ring rope skin of length because of the wire of fracture in this way, while to escaping Raw rope will not cause the wire in section is at random to cause incised wound user more safe when being cut.

Wherein rope skin includes weaving the inner rope skin constituted and by 12 second strands phases by 12 first strands are interlaced The outer rope skin that mutual weaving is constituted can play duplicate protection to wire rope core in this way, and inner rope skin and the mutual cooperation of outer rope skin can mention Its high frictional force and then fugitive anticreep when giving birth to sliding, and even if abrasion also inner rope skin pair occurs in use for rope skin outside Wire rope core is protected, more wear-resisting to prolong the service life, wherein the first strands and the second strands are by least 7 aramid fibers It constitutes, accordingly even when the wearability that can be further improved inner rope skin and outer rope skin prolongs the service life.

Detailed description of the invention

Fig. 1 is longitudinal schematic cross-sectional view of the utility model.

Fig. 2 is the schematic front view of the utility model.

Specific embodiment

As described below is only the preferred embodiment of the utility model, does not therefore limit the protection model of the utility model It encloses, the present invention will be further described with reference to the accompanying drawings and examples.

Embodiment, as shown in Fig. 1 to Fig. 2: a kind of escaping rope, it is characterised in that: including rope skin 20 and be set in rope skin 20 Interior wire rope core 10, wherein wire rope core 10 is twisted by 7 groups of main core groups 11, wherein main core group 11 twisted by 7 one metal wires 111 and At the intensity and service life that can improve wire rope core 10 in this way will not lead to whole one metal wire an one metal wire 111 has broken 111 are detached from wire rope cores 10, will not influence whole use, and will not protrude that length is too long to poke rope because of the wire 111 of fracture Figure for shadow-play rings the service life of rope skin 20.Wire 111 is using its good toughness of stainless steel wire and can prevent corrosion rope skin 20, into One step prolongs the service life.

Wherein rope skin 20 includes inner rope skin 21 and outer rope skin 22, and wherein inner rope skin 21 is by 12 interlaced volumes of first strands The surface for being configured to the inner rope skin 21 that braiding in this way is completed has asperities, is then arranged outside inner rope skin 21 by 12 second again Asperities on the outer rope skin 22 that the interlaced braiding of strands is constituted rope skin 22 outer in this way are mutually fitted with the asperities on inner rope skin 21 The frictional force between inner rope skin 21 and outer rope skin 22 should be increased in this way, avoid occurring to slide relatively, while wire rope core 10 can be played Duplicate protection, and inner rope skin 21 and the mutual cooperation of outer rope skin 22 can improve its frictional force and then fugitive anticreep when giving birth to sliding, and Even if rope skin 22 occurs to wear in use and protect there are also inner rope skin 21 to wire rope core 10 outside, more wear-resisting extension makes With the service life, wherein the first strands and the second strands are made of at least 7 aramid fibers, accordingly even when can be further improved inner rope The wearability of skin 21 and outer rope skin 22 prolongs the service life, and wherein the anti-flame retardant property of aramid fiber is strong, high temperature resistant, and intensity is high, Elongation percentage is low and cut resistant, can be preferably using the operation of varying environment long service life simultaneously.

Further, rope 20 color of skin is fluorescein, that is, adds fluorescent powder when being dyed in stain, can improve in this way Its identification can be quickly found out and be held when being escaped, and save the time of searching, more efficiently, in stain plus glimmering Light powder specific surface be covered with fluorescence coating its service life is longer and is avoided that surface layer falls off or wears leads to not be quickly found out, more It is efficient.

In production, 7 one metal wires 111 are first twisted together to form main core group 11 by strander, then take 7 again Root main core group 11 is twisted by strander into wire rope core 10, is then twisted aramid fiber, then adjusts 24 strands of braiders The space for placing new equipment is saved simultaneously for double 12 strands of braiders energy save the cost in this way, finally by the virtue after wire rope core 10 and twisting Synthetic fibre fiber is placed on the corresponding position of double 12 strands of braiders and carries out the rope skin 20 that inside and outside dual braiding composition is set in outside wire rope core 10.
