Abstract
The invention relates to a metallic corrugated pipe guard cable which belongs to a bridge guy cable or a suspension cable, comprising: a metallic corrugated pipe and a cable body inside the metallic corrugated pipe, wherein fillers are positioned between the metallic corrugated pipe and the cable body; the metallic corrugated pipe is a corrugated pipe made from stainless steel materials and aluminum or aluminum alloy materials or metallic materials with good corrosion resistance and favorable ocean and erosive industrial atmosphere erosiveness resistance, and the ripple shape of the metallic corrugated pipe is in a bamboo joint shape, a spiral shape or a vertical pivoting shape; the cable body is a steel wire bundle or a steel stranded wire bundle; and the fillers filled between the metallic corrugated pipe and the cable body are one of polyethylene, polyurenthane, asphalt, paraffin or anticorrosive grease materials. The metallic corrugated pipe guard cable has the good anticorrosive property and the long service life of an outer-layer jacket, therefore, the cable body is in an ideal anticorrosive environment for a long time, and the cable body has good corrosion resistance and long service life; in addition, the metallic corrugated pipe guard cable has good flexibility, is convenient to transport in a coiling way, and the outer-layer metallic corrugated pipe has less stress when the cable body stretches out.
Description
Technical field:
The present invention relates to a kind of bridge cable or hoist cable, particularly have the guard cable of corrosion proof function.
Background technology:
Domestic existing cable body protection all is to adopt the high density polyethylene (HDPE) parcel to protect with parallel wire unit after wrapped or steel strand through being wrapped, and its structure as shown in Figure 1 and Figure 2.It utilizes high density polyethylene (HDPE) protective jacket 7 and interior hdpe layer 8 with parallel wire unit or steel strand cable body and external environment isolation, plays the purpose of the inner cable body of protection.Because of outer protective sleeve---high density polyethylene (HDPE) is easily aging under the irradiation of sunlight, produces the crack, has reduced the anti-corrosion capability of cable body, the application life of having limited drag-line.For this reason, must regularly keep in repair, change, both increase maintenance cost, cause the accident potential of bridge again easily drag-line.
Summary of the invention:
The technical problem to be solved in the present invention is: provide that a kind of outer protective sleeve Corrosion Protection is good, the metallic corrugated pipe guard cable of protective jacket long service life, so that cable body is in the desirable anticorrosion environment for a long time, thus the application life of improving drag-line and even bridge.
The technical scheme that solves the problems of the technologies described above is: a kind of metallic corrugated pipe guard cable, the cable body that comprises metal bellows and be positioned at metal bellows has filler between metal bellows and the cable body.
Described metal bellows is to adopt stainless steel, aluminum or aluminum alloy material or have good corrosion-resistant, anti-ocean and bellows that metal material that bellows that the good metal material of aggressivity industrial atmosphere erosion performance is made or surface are coated with anticorrosive is made;
Described cable body is steel tendon or steel wire bundle;
Be filled in filler between metal bellows and the cable body and be a kind of among polyethylene, Polyurethane, pitch, paraffin or the grease material.
Further technical scheme of the present invention is: the bellows-shaped of described metal bellows is laemodipodiform or spirality or direct rotary shape.
Compared with prior art, the present invention's metallic corrugated pipe guard cable has following beneficial effect:
1, metallic corrugated pipe guard cable of the present invention is to adopt metal bellows to make the protective jacket of steel tendon or steel wire bundle cable body, the metal bellows that the metal material of employing corrosion resistance and good is made is compared with the high density polyethylene (HDPE) protective jacket, its corrosion resistance and good and have and be difficult for advantage aging, long service life, thereby its drag-line cable body of making is in the desirable anticorrosion environment for a long time, drag-line corrosion resistance and good, life-span are long, thereby reduced the maintenance cost of bridge, reduced accident potential.
2, owing to adopt metal bellows as protective jacket, the metallic corrugated pipe guard cable pliability is good, convenient with guard cable coiling transportation, and outer field metal protecting tube stress is less during cable body stretch-draw simultaneously.
3, the metal bellows of metallic corrugated pipe guard cable is easy to make, cost is low.
Be further described below in conjunction with the technical characterictic of drawings and Examples the present invention's metallic corrugated pipe guard cable.
