Description

Waterproof steel wire rope capable of transmitting signals

Technical Field

The utility model relates to a steel wire rope, in particular to a waterproof steel wire rope capable of transmitting signals.

Background

At present, when a deep well is used, a large waterproof electric appliance needs to be lifted vertically along the direction of a shaft, water or drilling fluid exists in the well, the steel wire rope needs certain waterproof performance and a signal transmission function, and a common steel wire rope does not have the signal transmission function and cannot transmit information.

Disclosure of Invention

In view of the above disadvantages, the present invention is directed to a waterproof wire rope capable of transmitting signals, which can perform a safe lifting function and also transmit signals.

The utility model relates to a waterproof steel wire rope capable of transmitting signals, which is characterized by comprising a rope core, a first layer of steel wires and a second layer of steel wires; the rope core comprises a communication cable core, a supporting piece, filling glue, a shielding body and a sheath; the communication cable core comprises a plurality of communication conductors and insulators, and the insulators are coated on the outer layers of the communication conductors; the shielding body is covered on the outer sides of the communication cable cores and the supporting pieces, filling glue is filled between the communication cable cores and the supporting pieces, and the sheath is covered on the outer side of the shielding body; the first layer of steel wire is trapezoidal galvanized steel wire, and the second layer of steel wire is Z type galvanized steel wire, and first layer of steel wire twists the system in the rope core outside, and the second layer of steel wire twists the system in the first layer of steel wire outside, and the direction of twist of first layer of steel wire and second layer of steel wire is opposite.

Compared with the prior art, the utility model has the advantages that:

(1) the rope core is provided with the communication cable core, so that signal transmission can be realized.

(2) The outer layer of the steel wire rope is respectively a trapezoidal and Z-shaped special-shaped steel wire, the metal sectional area is increased, and compared with a common steel wire rope, the whole steel wire rope has better sealing performance and higher breaking tension.

(3) The surface of the steel wire rope is smooth and sealed, external water or drilling fluid and the like are not easy to permeate into the steel wire rope, and the good internal communication function can be guaranteed.

(4) The utility model has larger lay length and lower elongation; the adjacent steel wires are opposite in twisting direction and have good anti-rotation performance.
