Abstract
The utility model relates to a steel wire rope for coal mine rescue. The steel wire rope is characterized in that a center strand and an outer layer strand are included, the outer layer strand wraps the outer side of the center strand which is a hemp rope, the outer layer strand comprises a communication copper wire and an outer layer steel wire, a plastic insulation layer wraps the outer surface of the communication copper wire, and the outer layer steel wire wraps the outer side of the plastic insulation layer. The steel wire rope has the advantages that audio conversation signal transmission can be carried out.
Description
Technical field
The utility model relates to a kind of steel wire rope, relates 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 rescuing rapidly and efficiently, cannot directly by personnel under effective communication line and ore deposit, link up, to rescue, bring a lot of inconvenience thus.
Summary of the invention
The purpose of this utility model is to provide a kind of can have the coalmine rescue steel wire rope that carries out the transmission of audio session signal.
Summary of the invention of the present utility model 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 central strand outside; Central strand is pledget, and outer layer strand comprises communication copper cash and a cover wire, in communication copper cash appearance, is coated with one deck plastic cement insulating barrier, and cover wire is coated on the outside of plastic cement insulating barrier.
The advantage that the utility model compared with prior art had is: the utlity model has lifting carrying and rescue people, monitor personnel's life security simultaneously, can carry out random audio session by the communication copper stranded conductor in outer layer strand, the utility model is to have high-strength tensile, do not rotate and steel wire rope that can transmission of information, adapts to rescue engineering used; This steel wire rope can be at high temperature resistant (more than 500 degree), low temperature resistant (subzero 200 degree), according to safety coefficient, carry the high strength of certain rescue personnel's weight, high rupture pull force, low rotating wire rope, 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.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
