Abstract
The invention relates to a wire line for coal mine rescue. The wire line is characterized by comprising a central bundle and an outer bundle. The outer bundle is covered outside the central bundle. The central bundle is pledget, the outer bundle comprises a communication copper wire twisted-pair line and an outer steel wire, a plastic insulating layer is covered outside the communication copper wire twisted-pair line, and the outer steel wire is covered outside of the plastic insulating layer. The wire line for coal mine rescue has the advantage of capability of conducting audio conversation signal transmission.
Description
Technical field
The present invention relates to a kind of steel wire rope, relate in particular to a kind of coalmine rescue steel wire rope.
Background technology
At present in order to ensure colliery industry generation security incident, when being rescued rapidly and efficiently, can't directly by personnel under effective communication line and ore deposit, be linked up, bring a lot of inconvenience to rescue thus.
Summary of the invention
The object of the present invention is to provide and a kind ofly can there is the coalmine rescue steel wire rope that carries out the transmission of audio session signal.
Summary of the invention of the present invention is: a kind of coalmine rescue steel wire rope is characterized in that it is comprised of central strand and outer layer strand; Outer layer strand is coated on the central strand outside; Central strand is pledget, and outer layer strand comprises communication copper wire twisted-pair feeder and a cover wire, in communication copper wire twisted-pair feeder appearance, is coated with one deck plastic cement insulating barrier, and cover wire is coated on the outside of plastic cement insulating barrier.
Anti-extrusion, non-deformability for the reinforced insulation layer in the hawser production process are added with glass fibre in the plastic cement insulating barrier.
In order to strengthen cable anti-flammability in use, form a flame-retardant layer after copper wire surface in communication copper wire twisted-pair feeder applies fire resistant fluid, fire resistant fluid comprises the component of following percentage by weight: chlorinated paraffin wax 10～20, bromo biphenyl ether 20～40, tri-chlorination two antimony 40～60.
The advantage that the present invention compared with prior art had is: the present invention has the lifting carrying and rescues the people, monitor personnel's life security simultaneously, can carry out random audio session by the communication copper stranded conductor in outer layer strand, the present invention has high-strength tensile, does not rotate and steel wire rope that can transmission of information, adapts to the rescue engineering used; This steel wire rope can be at high temperature resistant (more than 500 degree), low temperature resistant (subzero 200 degree), carry the high strength of certain rescue personnel's weight, high rupture pull force, low rotating wire rope according to safety coefficient, steel wire rope can crookedly be wound around, and can guarantee to rescue process steel wire rope unwrapping wire and rise to be wound around; The present invention also has good anti-flammability.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Specific embodiment
As shown in Figure 1, a kind of coalmine rescue steel wire rope, is characterized in that it is comprised of central strand 1 and outer layer strand 2; Outer layer strand 2 is coated on central strand 1 outside; Central strand 1 is pledget, and outer layer strand 2 comprises communication copper wire twisted-pair feeder 2.1 and a cover wire 2.2, in copper wire twisted-pair feeder 2.1 appearances, is coated with one deck plastic cement insulating barrier 2.3, and cover wire 2.2 is coated on the outside of plastic cement insulating barrier 2.3; Steel cord structure is 4V * 39S+FC; Be added with glass fibre in plastic cement insulating barrier 2.3; Form a flame-retardant layer after copper wire surface in communication copper wire twisted-pair feeder 2.1 applies fire resistant fluid, fire resistant fluid comprises the component of following percentage by weight: chlorinated paraffin wax 15, bromo biphenyl ether 30, tri-chlorination two antimony 55.
