Description

A kind of steel wire rope reinforced fault self feed back shuttle car cable

Technical field

The utility model relates to field of cable technology, particularly relates to a kind of steel wire rope reinforced fault self feed back shuttle car cable.

Background technology

Shuttle car cable, in use along with the motion of shuttle car, is in all the time and is wound---under the cycle movement state that stretching---reeling---is stretching more again.Because underworkings is very narrow, cable has the possibility injured by a crashing object by the borehole wall or coal cinder at any time, and be also subject to the restriction of cable hank capacity and shuttle car range ability, the external diameter of cable also must have strict restriction.For these reasons, the useful life of cable is very short, often comes into operation and how long will not break down, cause the shut-down of shuttle car, directly impact is mined and normally the carrying out of driving, and occurs that maximum faults is exactly disconnected core, general disconnected core cable substantially cannot field repair, just need to change cable, but limited because of operational environment, underworkings is narrow, change very difficult, expense people is wasted time and energy, and this is just badly in need of a kind of novel shuttle car cable of research and development, improves the useful life of shuttle car cable.
