Abstract
The utility model provides a stretchable shock-resisting fracture-preventing guide pipe, and relates to the technical field of guide pipes used for conveying gas and liquid or protecting electric cables, optical cables and other cable products. The stretchable shock-resisting fracture-preventing guide pipe overcomes the technical defects that existing guide pipes and cables used for conveying the gas and the liquid fracture easily. The stretchable shock-resisting fracture-preventing guide pipe is characterized by comprising an inner guide pipe and an outer guide pipe installed outside the inner guide pipe, and the inner guide pipe and the outer guide pipe are respectively composed of an elastic spiral layer and an outer covering layer, wherein the outer covering layers are installed on the elastic spiral layers. The stretchable shock-resisting fracture-preventing guide pipe composed of multiple layers of the spiral layers has very good shock resistance and fracture-preventing and stretchable performance, can be used for conveying the gas and the liquid and being made into the electric cables, the optical cables and other cable products, and is applied to bridges, culverts, mines, underwater cables and the like.
Description
Technical field
The utility model relates to for transport gas, liquid, or cable series products such as cable, optical cable are protected used microcatheter technology field.
Background technique
In the engineer operation process; often can use the conduit for transport gas or liquid; by this conduit gas or liquid are transferred in the corresponding equipment; because operating environment is abominable; as: during the pneumatic pick operation, air-transmitting conduit is in strong vibrations or pull appearance fracture easily in the process frequently.Equally, also there is the damaged technical problem of fracture in the various cables in the engineer operation process.
Summary of the invention
In sum, the purpose of this utility model is to solve the conduit of existing transport gas, liquid and the cable technical deficiency of fracture and the anti-fracture conduit of a kind of antidetonation that stretches that proposes easily.
For solving the technical problem that the utility model proposes, the technological scheme of employing is: the anti-fracture conduit of a kind of antidetonation that stretches is characterized in that described conduit includes inner conductor and the outer conductor of being located at the inner conductor outside; Described inner conductor and outer conductor constitute by elastic helix layer and the serving of being located on the elastic helix layer.
Be socketed with two-layer above outer conductor on the described inner conductor successively.
Described elastic helix layer is reeled by elastic metallic yarn and is constituted.
Be in the serving thickness of outermost outer conductor greater than the serving of other each outer conductor and inner conductor.
Also be provided with transmitting catheter in the described inner conductor.
Use the cable of described conduit, it is characterized in that including successively from outside to inside in the described inner conductor protective tube, packed layer and heart yearn.
The beneficial effects of the utility model are: the utility model adopts multilayer by the conduit that spiral layers constitutes, and has good shock resistance, anti-fracture stretchable performance.Can be used for transport gas, liquid and make cable series products such as cable, optical cable.Be applied to bridge, culvert, mine and underwater cable etc.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and the preferred specific embodiment of the utility model structure of the present utility model is further described.
Shown in Fig. 1, cable described in the utility model includes the heart yearn 11 of non-elastic material, adopt than soft material packed layer and protective tube 12 outside of heart yearn 11, heart yearn 11 packed layers and protective tube 12 constitute common cable 1, the utility model also has additional inner conductor 2 and the outer conductor 3 of being located at inner conductor 2 outsides at the skin of common cable, and inner conductor 2 is made of elastic helix layer 21 and the serving of being located on the elastic helix layer 21 22; Outer conductor 3 is identical with inner conductor 2 structures, is made of elastic helix layer 31 and the serving of being located on the elastic helix layer 21 32 equally.In specific implementation process, as required, also outer conductor that can be two-layer or more multi-layered.
Described elastic helix layer 21,31 all adopts the elastic metallic yarn coiling making preferably of elasticity and toughness, the elastic helix layer 31 toughness intensity of outer conductor 3 are greater than the elastic helix layer 21 of inner conductor 2, during multilayer outer conductor 3, more by outward, toughness intensity is more big, and reaching can stretch as spring can not rupture.To break in order wearing and tearing, to be in the serving thickness of outermost outer conductor greater than the serving of other each outer conductor and inner conductor.
When the utility model is used as the conduit of transport gas or liquid, keep above-mentioned inner conductor 2 and outer conductor 3 part-structures of being located at inner conductor 2 outsides, can in described inner conductor 2, establish a transmitting catheter in the time of necessary.
Claims (6)
