Abstract
The invention discloses an electric traction rope. The electric traction rope comprises an inner core layer, a middle layer and an outer wrapping layer, wherein the inner core layer is formed by twisting multiple soft steel wires; the middle layer adopts cotton hemp ropes which are interwoven in a crossed manner and wrap the inner core layer; the outer wrapping layer is tubular wear-resistant rubber wrapping the middle layer. The inner core layer is formed by twisting the multiple steel wires, the strength of a traction rope body is better due to the fact that the steel wires have better strength; besides, the middle layer adopts the interwoven cotton hemp ropes wrapping the steel wire ropes, so that the steel wires are wadded up and not prone to falling, and the strength is improved; the outer wrapping layer is made from wear-resistant rubber, on one hand, rubber has good insulation performance, and on the other hand, the wear resistance and the toughness of the traction rope is improved.
Description
Technical field
The present invention relates to electrical equipment technical field, relate to a kind of electric traction rope.
Background technology
At present, in electric power cable unwrapping wire process, mostly be steel wire rope as pull rope, there is many shortcomings in steel wire rope: as heavier in steel wire rope self, carrying unfolding difficulty, and tractive force is large; During steel wire rope operation in the wild, required machinery, Ren Yuanduo, damage crop area large; Cord strength is not high enough; Wire Rope Production poor stability, easily weares and teares and produces hangnail, threatens operator safety; Maintenance difficulty preserved by steel wire rope, and easy-to-rust is aging, and use cost is high; Steel wire rope insulating properties extreme difference, occurred causing human casualty accident in power line construction.Twist with the fingers peripheral hardware sheath again to form.But power circuit construction operating mode becomes increasingly complex now, also more and more higher to the requirement of electric traction rope.Particularly the smaller the better to the requirement of the structural elongation of electric traction rope.
Summary of the invention
(1) technical problem that will solve
In order to overcome prior art deficiency, a kind of good insulation preformance is now proposed, the novel electric power pull rope that structural elongation is low.
(2) technical scheme
Of the present inventionly to be achieved through the following technical solutions: the present invention proposes a kind of electric traction rope, it comprises inner sandwich layer, intermediate layer and outer casing, described inner sandwich layer is that some strands of stone dead wires are kneaded and formed, described intermediate layer is the cotton rope made of hemp and the establishment that interlocks in cross is wrapped on inner sandwich layer, and described outer casing is that tubulose abrasive rubber entirety is wrapped on intermediate layer.
(3) beneficial effect
The present invention, relative to prior art, has following beneficial effect:
A kind of electric traction rope that the present invention mentions, what its inner sandwich layer adopted is that steel wire strand is kneaded and formed, because steel wire has good intensity, make pull rope main body intensity better, intermediate layer adopts the establishment of the cotton rope made of hemp to be wrapped in steel wire rope surface in addition, it is in aggregates that it can make steel wire rope encircle, each stock steel wire difficult drop-off, improve intensity, the abrasive rubber that outer casing adopts is made, rubber has good insulating properties on the one hand, improves the ABRASION RESISTANCE of pull rope and the toughness of rope body on the other hand.

1-inner sandwich layer; 2-intermediate layer; 3-outer casing.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
A kind of electric traction rope as depicted in figs. 1 and 2, it comprises inner sandwich layer 1, intermediate layer 2 and outer casing 3, described inner sandwich layer 1 forms for some strands of stone dead wires are kneaded, described intermediate layer 2 is the cotton rope made of hemp and the establishment that interlocks in cross is wrapped on inner sandwich layer 1, and described outer casing 3 is wrapped on intermediate layer 2 for tubulose abrasive rubber entirety.
Embodiment recited above is only be described the preferred embodiment of the present invention, not limits the spirit and scope of the present invention.Under the prerequisite not departing from design concept of the present invention; the various modification that this area ordinary person makes technical scheme of the present invention and improvement; all should drop into protection scope of the present invention, the technology contents of request protection of the present invention, all records in detail in the claims.
Claims (1)
1. an electric traction rope, it comprises inner sandwich layer (1), intermediate layer (2) and outer casing (3), it is characterized in that: described inner sandwich layer (1) is kneaded for some strands of stone dead wires and formed, described intermediate layer (2) is for the cotton rope made of hemp and be wrapped on inner sandwich layer (1) in the cross establishment that interlocks, and described outer casing (3) is wrapped on intermediate layer (2) for tubulose abrasive rubber entirety.
