Technical Field

The invention relates to the technical field of rescue, in particular to an emergency rescue rope and a manufacturing method thereof.

Background

Emergency rescue ropes are classified into three categories according to their technical properties and specific uses: the power rope, the static rope and the fire safety rope have larger difference in use field and use working condition, and completely different technical index systems are required for evaluating and representing the ropes. The power rope is a protection rope used under the working condition that the instantaneous falling risk exists in the field of safety protection, and the falling coefficient of the protection rope is more than 0.3, such as mountain climbing and rock climbing and high-altitude operation; the static rope is a protective rope used in the fields of slow descent, fast descent, work positioning and high-altitude suspension in the safety protection field; the fire safety rope is a rope which is specially used for carrying people by fire-fighting troops in fire-fighting rescue, emergency rescue and disaster relief or daily training, the rope requires high strength, low extension, wear resistance, high temperature resistance and flame retardance, and the rope is divided into a light safety rope and a universal safety rope according to the diameter and breaking strength.

When the existing emergency rescue rope is used in the application fields of fire rescue, resource exploration, oil exploitation, electric power construction, outdoor sports, emergency rescue and disaster relief and the like, the used length and the residual length of the rope need to be known, so that the length of the rope is mastered, the rope is prevented from falling off, and the safety of a user is ensured.

Disclosure of Invention

The invention aims to solve the problems in the prior art, and provides an emergency rescue rope and a manufacturing method thereof, so that the defect that a rope mark is easy to disappear is overcome, a permanent mark is realized, and the damage of pigment or other chemical substances to the rope is avoided.

The utility model provides an emergency rescue rope, includes first rope core, second rope core, basic unit and identification portion, the basic unit is equipped with an at least first rope skin, identification portion is equipped with an at least second rope skin and an at least third rope skin, the second rope skin with the third rope skin is alternately, the second rope skin with first rope skin is parallel to make identification portion be different from the basic unit.

Preferably, the first rope skin is provided with first grains, and the second rope skin and the third rope skin are combined to form second grains.

Preferably, the base part and the identification part are respectively provided with a plurality of fourth rope skins and a plurality of fifth rope skins which are mutually crossed.

Preferably, the first cord is located inside the base portion, and the second cord is located inside the identification portion.

A manufacturing method of an emergency rescue rope comprises the following steps:

the first step is as follows: manufacturing a rope sheath, combining the rope sheath into one strand by a twisting machine, weaving the combined rope sheath into cloth by a knitting machine, and performing sizing treatment;

the second step is that: manufacturing a first rope core and a second rope core, and shaping the first rope core and the second rope core after primary twisting and secondary twisting;

the third step: pre-weaving the rope skin, doubling the rope skin on a pre-weaving machine, and doubling the thread on a bobbin of a weaving machine;

the fourth step: spooling, namely spooling the shaped rope core on a spooling machine to obtain a rope core yarn drum;

the fifth step: and weaving, namely butting the base part and the identification part by an air splicer joint method, or changing the texture of the base part into the identification part by a texture changing non-joint method, and butting the first rope core and the second rope core at the same time.

Preferably, the air splicer joining method is to overlap the base part and the identification part by an air splicer and then trim the overlapped base part and identification part.

Preferably, the texture changing jointless method is to change the base part into the identification part by changing a moving spool of a knitting machine.

According to the emergency rescue rope and the manufacturing method thereof, the length of the remaining rope can be estimated through the difference between the base part and the identification part in the processes of fire safety rescue, outdoor sports, emergency rescue, rapid descent, hole exploration, descending and coiling in industrial operation, meanwhile, the mark is permanent, chemical damage to the rope caused by the mark of pigment or other chemical substances can be avoided, and the emergency rescue rope is safer and more reliable.
