Anti-bending towline cable

Technical Field

The utility model relates to the technical field of cables, especially, relate to an anti tow chain cable of buckling.

Background

The towline cable is a cable which is placed in a cable towline, can effectively prevent the cable from being entangled, abraded, pulled off and scattered, is mainly used in occasions where equipment units need to move back and forth, and has high flexibility; conventional tow cable structures resemble caterpillar tracks and are therefore also referred to as tank chain cables or tow cables.

In the actual use process, people usually bend the drag chain cable up and down along with the drag chain. Because the inside many conductors that are equipped with of tow chain cable, and many conductors are pasted the clothes setting each other, when buckling from top to bottom to the tow chain cable, lead to the looks mutual friction between the conductor easily to the condition of conductor damage takes place, make the anti performance of buckling of tow chain cable not high, after buckling many times easily, its inside takes place to damage, leads to the unable normal use of tow chain cable. And because the inside solid construction that is of tow chain cable has led to people and has gone on when buckling from top to bottom, need adopt great effort, this also leads to the bending of tow chain cable to appear the fracture on the department surface, the condition that can break when serious.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an anti tow chain cable of buckling has better anti performance of buckling, can reduce the damage to internal conductor at the in-process of buckling, avoids the production of tow chain cable surface crack when buckling simultaneously.

The utility model discloses an anti tow chain cable that buckles adopts technical scheme is:

the utility model provides an anti tow chain cable of buckling, includes a plurality of conductors, wraps up in the outside insulating layer of conductor, the outside parcel of insulating layer has the lag, it has the filling layer to fill between lag and the insulating layer, the filling layer middle part is equipped with the extrusion cavity, a plurality of the conductor becomes two rows of settings, the conductor sets up respectively in the upper and lower both sides of extrusion cavity, and with one side the conductor sets up according to the same interval.

Preferably, the conductors on the upper side and the lower side of the extrusion cavity are arranged in a staggered mode.

As a preferred scheme, a plurality of steel strands are arranged inside the filling layer and arranged between the conductors.

Preferably, the protective sleeve comprises an inner sleeve and an outer sleeve, and the outer sleeve is wrapped on the surface of the inner sleeve.

The utility model discloses an anti tow chain cable of buckling's beneficial effect is: be equipped with the insulating layer in the conductor outside, avoided in the use, the conductor causes the influence to people or equipment to play the effect of daily protection to the conductor through the outside lag of insulating layer. The conductors are divided into two rows and arranged at the same interval, and are respectively arranged on the upper side and the lower side of the extrusion cavity, so that when the drag chain cable is bent up and down, the conductors are not contacted with each other, and the damage caused by mutual friction among the conductors is reduced. And be equipped with the extrusion cavity in tow chain cable inside, when the tow chain cable buckles from top to bottom, can extrude the extrusion cavity inside of tow chain cable department of buckling, make inside sufficient space of having of tow chain cable buckle and warp, avoid because the tow chain cable is whole comparatively thick, be difficult to buckle, when the effort of buckling is great, can lead to the surface of tow chain cable to appear the crack, the appearance of having avoided this kind of condition, thereby the anti bending performance of tow chain cable has been improved, the life of tow chain cable is improved.

Drawings

Fig. 1 is a schematic cross-sectional view of the anti-bending towline cable of the present invention.

Detailed Description

The invention will be further elucidated and described with reference to the following embodiments and drawings in which:

referring to fig. 1, an anti-bending towline cable includes a plurality of conductors 10, an insulating layer 11 wrapping the outside of the conductors 10, a protective sleeve 12 wrapping the outside of the insulating layer 11, a filling layer 13 filled between the protective sleeve 12 and the insulating layer 11, an extrusion cavity 14 disposed in the middle of the filling layer 13, the plurality of conductors 10 arranged in two rows, the conductors 10 respectively disposed on the upper and lower sides of the extrusion cavity 14, and the conductors 10 disposed on the same side are disposed at the same interval.

The insulating layer 11 is arranged outside the conductor 10, so that the influence of the conductor 10 on people or equipment in the use process is avoided, and the daily protection effect on the conductor 10 is achieved through the protective sleeve 12 outside the insulating layer 11.

The conductors 10 are divided into two rows and arranged at the same interval, and the conductors 10 are respectively arranged at the upper and lower sides of the extrusion cavity 14, so that when the drag chain cable is bent up and down, the conductors 10 are not contacted with each other, and the damage caused by mutual friction among the conductors 10 is reduced.

And be equipped with extrusion cavity 14 in tow chain cable inside, when the tow chain cable buckles from top to bottom, can extrude the 14 insides of extrusion cavity of tow chain cable department of buckling, make inside sufficient space of having of tow chain cable buckle and warp, avoid because the tow chain cable is whole comparatively thick, be difficult to buckle, when the effort of buckling is great, can lead to the surface of tow chain cable to appear the crack, the appearance of this kind of condition has been avoided, thereby the anti bending performance of tow chain cable has been improved, the life of tow chain cable is improved.
