Embodiment Construction

[0044] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0045] This embodiment provides a figure 1 The production method of the deep well rescue wire rope shown in the video includes:

[0046] Step one includes:

[0047] Twisting one center steel wire and several outer layer steel wires to make outer layer strands, the twist direction is left twist. In this embodiment, one center steel wire of 1.12 mm and six outer layer steel wires of 0.96 mm are twisted by a twisting machine to form an outer layer strand, the diameter of which is 2.77 mm, the lay length is 24.0 mm, and the twist direction is left twist.

[0048] Twisting one central steel wire, several inner and outer layer steel wires, several second outer layer thick wires, several second outer layer thin wires and several outer layer wires into a central strand, the twisting direction is left twist. In this embodiment, 1 central steel wire of 0.53 mm, 5 in...

Abstract

The invention discloses a production method of a video deep well rescue steel wire rope. The production method comprises the following steps of twisting an outer layer strand, twisting a central strand, twisting to form an inner-layer metal strand, twisting a plurality of galvanized steel wires and an optical cable containing a stainless steel flat wire into a finished optical cable, twisting filling strands, twisting the inner-layer metal strand, the finished optical cable, the filling strands and the central strand into a rope core, spirally distributing the finished optical cable in the steel wire rope along the extension direction of the steel wire rope, adopting active magnetic damping pay-off for the finished optical cable in the twisting process, adopting passive pay-off for other steel wire strands, performing one-time rope combination on each strand and the finished optical cable, and enabling the twisting direction of the outer layer strand to be opposite to that of the rope core. When the video deep well rescue steel wire rope is twisted, the finished optical cable and the steel wire strands are consistent in pay-off tension, the active magnetic damping pay-off is adopted for the finished optical cable, and the steel wire rope produced through the production method has the advantages of being high in bearing performance and capable of effectively transmitting video signals.

Description

technical field [0001] The invention relates to a production method of a steel wire rope, in particular to a production method of a deep well rescue steel wire rope with visual information. Background technique [0002] When a deep coal mining accident occurs, how to take rescue measures safely, quickly and correctly is a technical problem faced by the coal industry and the safety industry. However, the steel wire ropes produced according to the current steel wire rope production methods cannot meet the characteristics of high load-bearing performance and effective transmission of video signals, which makes it impossible to understand the situation in the mine in real time during deep mine rescue, greatly reducing the rescue efficiency. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a production method of a deep well rescue wire rope with safe bearing, long-distance lifting, and visual communication.
