Abstract

The utility model discloses a four-stranded sisal core, which comprises four sisal yarn strands and one central fine sisal yarn strand, wherein the four sisal yarn strands are positioned around the central fine sisal yarn strand and then twisted and wrapped symmetrically. The four-stranded sisal core has the advantages of simple structure and convenience in use. Due to the structure of twisting and wrapping the four sisal yarn strands around the central fine sisal yarn strand, the supporting strength of the sisal core is strengthened and the service life of a sisal-core steel wire rope adopting the structure is prolonged.

Description

A kind of four strands of structure sisal hemp cores

Technical field

The utility model relates to the sisal hemp core that a kind of elevator wire rope uses, and specifically a kind of four strands of structure sisal hemp cores belong to elevator and make the field.

Background technology

The structure that elevator is made up of steel strand (strand) and wire rope core with steel wire rope.Usually elevator adopts 8 bursts of structures with steel wire rope, twists with the fingers sisal hemp core twisting by 8 steel wire rope bags and forms, and wire rope core main effect in elevator wire rope has: 1, supporting role, and the sisal hemp core guarantees the support to the steel wire rope outer layer strand; 2, oil storage effect contains enough greases in the sisal hemp core, guarantee lubricating when steel wire rope uses.The employed sisal hemp core of wire rope core is 3 strands of structure sisal hemp cores in the present steel wire rope, and structurally not good with 8 strand steel wire ropes coupling, sisal hemp heart yearn density is on the low side simultaneously, to the underbraced of steel wire rope.

The utility model content

The objective of the invention is to,, designed a kind of four strands of structure sisal hemp cores at the problems referred to above.

The technical solution of the utility model is: a kind of four strands of structure sisal hemp cores, comprise sisal hemp yarn thigh, and described sisal hemp core comprises careful sisal hemp yarn thigh in 4 strands of sisal hemp yarn thighs and 1 strand, careful sisal hemp yarn thigh during described 4 strands of sisal hemp yarn thigh bags are twisted with the fingers.

Described 4 strands of sisal hemp yarn thighs are arranged in the bag of symmetry on every side of careful sisal hemp yarn thigh and twist with the fingers.。

The sisal hemp core of described four bursts of structures structurally mates 8 strands of elevator wire ropes more, can increase its activity coefficient from structure, improves support degree.

The sisal hemp core of described four bursts of structures, because middle pericardium is twisted with the fingers a thin sisal hemp yarn thigh, self main line density also increases on 3 strands of sisal hemp cores of same specification, thereby improves the support degree of sisal hemp core to elevator wire rope.

Advantage of the present utility model is: the result is simple, and is easy to use, and improved the support degree of sisal hemp core, prolonged service life.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment.

The specific embodiment

Below preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in qualification the utility model.

As shown in Figure 1, OneKind of four strands of structure sisal hemp cores comprise sisal hemp yarn thigh, and described sisal hemp core comprises careful sisal hemp yarn thigh 2 in 4 strands of sisal hemp yarn thighs 1 and 1 strand, described sisal hemp yarn thigh 1 with in careful sisal hemp yarn thigh 2 mix sth. made by twisting mutually; Described 4 strands of sisal hemp yarn thighs 1 be arranged in careful sisal hemp yarn thigh 2 around.

Because steel wire rope is 8 bursts of structures, is used 4 strands of structure sisal hemp cores, tightness is better, can suitably improve the support degree of hemp core.

It should be noted that at last: the above only is preferred embodiment of the present utility model, be not limited to the utility model, although the utility model is had been described in detail with reference to previous embodiment, for a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.

Claims

1. one kind four strands structure sisal hemp cores comprise sisal hemp yarn thigh, it is characterized in that: described sisal hemp core comprises careful sisal hemp yarn thigh in 4 strands of sisal hemp yarn thighs and 1 strand, careful sisal hemp yarn thigh during described 4 strands of sisal hemp yarn thigh bags are twisted with the fingers.

2. a kind of four strands of structure sisal hemp cores according to claim 1 is characterized in that described 4 strands of sisal hemp yarn thighs are arranged in the bag of the symmetry on every side sth. made by twisting of careful sisal hemp yarn thigh.
