Abstract

A length measurable strengthen cable comprises a steel wire rope arranged in the center of the cable, a plurality of signal lines distribute around the steel wire rope, and a jacket that wraps the steel wire rope and the signal lines tightly. The jacket is equipped with a marking ring every a certain span on the outer surface along the length direction, the outer flank of the marking ring is wrapped with a layer of transparent shielding film so to prevent the marking ring form shedding off the jacket, thereby the cable is capable of working stably when measuring; meanwhile, it will not affect the user to reed the mark for the shielding film is transparent, the shielding film can also protect the protecting jacket and the marking ring, thereby the cable provided by the utility model is reliable in quality and not apt to abrasion.

Description

A kind of enhancing cable of measurable length

Technical field:

The utility model relates to a kind of cable, relates in particular to a kind of enhancing cable of measurable length.

Background technology:

Along with the continuous development of science and technology, various device emerges in an endless stream, and stube cable not only only is used for Data transmission and signal.For example, portable inclinometer is that inclino-probe is put into the underground by the deviational survey pipe in use, elevate piecemeal with cable then, every one section range of lift, read numerical value one time, therefore, the user generally can engrave dimension mark in order to measure at cable surface, and at present, most of users establish a Marking ring every a segment distance card at cable surface to finish monitoring along its length, but facts have proved, cable is in long-term use, can be often and ground or deviational survey tube wall bump, so Marking ring be easy to come off or be shifted, thereby can not normally measure; Simultaneously, cable quality of the prior art is also unreliable, and is not wear-resisting, and load bearing stength is also not enough.

The utility model content:

The technical problem that the utility model solves is the deficiency that overcomes above-mentioned prior art, and a kind of cable of measurable length is provided, and it is working stability not only, and reliable in quality, and is very wear-resisting, and simultaneously, tensile strength also increases greatly.

The enhancing cable of a kind of measurable length that provides according to the utility model; comprise the steel cable that is positioned at the center, be distributed in many holding wires of this steel wire rope periphery and the sheath that described steel wire rope and described holding wire are tightly wrapped; the outer surface of described sheath is provided with a Marking ring every a determining deviation along its length, and the outside of described Marking ring is covered with the transparent protective film that one deck can prevent that it from coming off.

The utility model also has following attached technical characterictic:

Described Marking ring can be on described sheath, also can be integrally formed with described sheath.

Described Marking ring has yellow and red two kinds, and the Marking ring of two kinds of colors is alternately distributed.

Described steel wire rope is formed by heart yearn with the insulating outer layer of its parcel; Described heart yearn is closed by many galvanized mild steel skein silks and forms, and described insulating outer layer is a black PVC.

Described holding wire is formed by wire stylet with the insulating outer layer of its parcel, and described wire stylet is by many stranded the forming of bare copper wire, and described insulating outer layer is the low pressure low density PE.

Described sheath is a polyurethane jacket.

The enhancing cable of a kind of measurable length that provides according to the utility model, prior art has following advantage relatively:

At first, the utility model is covered with the layer of transparent diaphragm in the outside of Marking ring, comes off from sheath to prevent Marking ring, thereby makes cable working stability when measuring; Simultaneously,, do not read mark, but also can play the effect of protection sheath and Marking ring, thereby the cable quality that makes the utility model provide is reliable so not only can not have influence on the user because diaphragm is transparent, not easy to wear.

Secondly, cable of the present utility model is provided with steel wire rope at the center, has strengthened the tensile strength of cable greatly.

Description of drawings:

The embodiment that provides below in conjunction with accompanying drawing is elaborated to the utility model:

The structural representation of the enhancing cable of a kind of measurable length of providing according to the utility model is provided Fig. 1, among the figure, draws the yellow Marking ring of region representation of oblique line, draws the region representation red-label ring of cross spider;

Fig. 2 be among Fig. 1 along the schematic sectional view of A-A direction, clear in order to represent, Marking ring and transparent protective film do not have cross-hatching among the figure.

Embodiment:

Referring to Fig. 1 and Fig. 2; the enhancing cable of a kind of measurable length that provides according to the utility model; comprise the steel cable 1 that is positioned at the center; be distributed in the many holding wires 2 of this steel wire rope 1 periphery and the sheath 3 that described steel wire rope 1 and described holding wire 2 are tightly wrapped; the outer surface of described sheath 3 is provided with a Marking ring 31 every a determining deviation (deciding according to actual the requirement) along its length; the outside of described Marking ring 31 is covered with one deck can prevent its transparent protective film that comes off 4; thereby make cable working stability when measuring; simultaneously; because diaphragm is transparent; do not read mark so not only can not have influence on the user; but also it is frayed to play protection sheath and Marking ring, thereby the cable quality that makes the utility model provide is reliable.Wherein: steel wire rope 1 requires to have intensity preferably, and is enough solid to guarantee cable; Sheath 3 is a polyurethane jacket, and itself and steel wire rope 1 and holding wire 2 require to wrap very tightly, the play that do not have, smooth surface is even, the pockmark that do not have, bubble, subside, trachoma etc.

As mentioned above, the utility model provides two kinds of execution modes to the setting of Marking ring 31: a kind of be with described Marking ring 31 on described sheath 3, at this moment, because the existence of transparent protective film 4, can prevent that Marking ring 31 from moving up and down and be unlikely to come off; Another kind is that Marking ring 31 and described sheath 3 is integrally formed; for example, at a certain distance sheath 3 surfaces along the circumferential direction on color and form Marking ring 31, at this moment; because the existence of transparent protective film 4 can prevent that Marking ring 31 from coming off with extraneous the contact because of wearing and tearing.Described Marking ring 31 has yellow and red two kinds, and the Marking ring 31 of two kinds of colors is alternately distributed, and better reads mark to make things convenient for the user.

Described steel wire rope 1 is formed by heart yearn 11 with the insulating outer layer 12 of its parcel; Described heart yearn 11 is closed by many galvanized mild steel skein silks and forms, and described insulating outer layer 12 is a black PVC, can guarantee steel wire rope 1 not oxidation.Described holding wire 2 is formed by wire stylet 21 with the insulating outer layer 22 of its parcel, and described wire stylet 21 is by many stranded the forming of bare copper wire, and described insulating outer layer 22 is the low pressure low density PE, and is not oxidated to guarantee holding wire.

The foregoing description is only for the usefulness that the utility model is described; and be not to restriction of the present utility model; the those of ordinary skill in relevant technologies field; under the situation that does not break away from spirit and scope of the present utility model; can also make various variations and modification; therefore all technical schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by each claim.
