Blank pipe, described blank pipe is connected as a single entity with the oversheath of main push-towing rope.
Described oversheath, sheath, blank pipe are PE/PVC/ low smoke and zero halogen or other conventional sheath materials are made.
Described main push-towing rope is coaxial cable, including inner wire and be the most sequentially coaxially coated with in the conductor
Insulating barrier, screen layer and oversheath.
Described auxiliary cable is self-supporting line, including zinc-coated wire and the sheath that is wrapped on zinc-coated wire.
The beneficial effects of the utility model are:
The brand-new construction of cable that a kind of pipeline group coaxial cable is cable+blank pipe formula that this utility model provides,
The i.e. side at traditional cable increases one or more blank pipe, in order to expand tradition when required by blank pipe
The use function of cable, not only novel in design flexible, meet user's demand instantly, and for produce from now on
Product upgrading spare interface；Simultaneously because the extrusion of electric wire is the most complicated, obtain stable, complete
Beautiful cable profile, whole extruding production line (includes the steps such as unwrapping wire, protective cover material extrusion, cooling, take-up)
All must realize perfect cooperation, the manufacture method that this utility model provides be effectively ensured blank pipe roundness,
Mutually coordinated property between modules and main push-towing rope external diameter, blank pipe internal orifice dimension and the stability of external diameter.

Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in further detail, but this utility model not office
It is limited to following example.
As it is shown in figure 1, a kind of pipeline group coaxial cable, including the main push-towing rope 1 being arranged in parallel, auxiliary cable 2 with empty
Pipe 3.
Described main push-towing rope for providing the transmission medium of signal to various types of communication system；Described main push-towing rope can be coaxial electrical
Cable, including inner wire and be the most sequentially coaxially coated with insulating barrier in the conductor, screen layer with outer
Sheath.
Described auxiliary cable module is for providing miscellaneous function for whole cable；Described auxiliary cable can be for whole cable
There is provided the self-supporting line of bearing function, including phosphating steel wire and the sheath that is wrapped on phosphating steel wire.Described master
The oversheath 11 of cable is connected as a single entity with the sheath 21 of auxiliary cable；
Described blank pipe can be easy to follow-up maintenance and function and expand, blank pipe be tubular structure and blank pipe with
The oversheath of main push-towing rope is connected as a single entity, and the inside of blank pipe is provided with axially extended cavity 31.Described oversheath, protect
Set, blank pipe are PE and make.
The manufacture method of a kind of pipeline group coaxial cable, comprises the following steps:
1) main push-towing rope, auxiliary cable are released by pay off rack, and stretch in the jacket mould of extruder；
2) make the cable core hole of jacket mould keeps vacuum and in blank pipe bushing pipe, inputs gas-pressurized；
3) CABLE MATERIALS adds heat fusing through extruder and is shaped to the oversheath of main push-towing rope, auxiliary cable by jacket mould
Sheath and blank pipe；
4) by gradual change type cooler (omitting in figure), cable is cooled down, wherein, first use 60-80
DEG C water cooling cable, then use the room temperature water cooling cable of 20-30 DEG C, finally use the water of 0-15 DEG C
Cooling cable；
5) cable after cooling i.e. can get cable finished product through traction machine and admission machine again.
Described pay off rack uses automatic paying-off device, becomes with constant-tension drawn out cable with no damage half during work
Product.
Step 2) in pressure can determine as required, preferably vacuum pressure is 0.1-0.3bar, adds and calms the anger
The pressure of body is 1-8bar.
The compound gas flow controller of described friendship is for guaranteeing the Stability Analysis of Structures of modules of cable and mutually coordinated；
As shown in Figure 4, the compound gas flow controller of described friendship includes vacuum generator and high pressure gas generator.Described
Vacuum generator for increasing the stability of main push-towing rope and auxiliary dimension, including the vacuum blower in turn switched on,
It is provided with vacuum tube and the vacuum suction pipe of regulating QI valve；The core rod of described vacuum suction pipe and jacket mould
Cable core hole is docked.Described high pressure gas generator is for providing steady for firm output mask and not yet cooling blank pipe
Fixed and constant pressure is such that it is able to guarantee that the stable of hollow tubular structure (produces stable interior supercharging inside blank pipe
To prevent blank pipe from shrinking)；Described high pressure gas generator includes that the air inlet pipe in turn switched on, air pressure control
Valve, air-flow converting interface and breather；With sheath grinding tool while that described breather stretching in vacuum suction pipe
Core rod blank pipe bushing pipe docking, described air inlet pipe is docked with external air source.
As shown in Fig. 5, Fig. 6 and Fig. 7, described jacket mould includes die sleeve A2 and mold core A 1.Described die sleeve
On be shaped with shield bore A21 and internal taper hole A22, described shield bore with connect before and after internal taper hole and pass through from left to right
The length direction of logical die sleeve.The left end being shaped with cable core hole A11 and core rod on described core rod is the prominent of taper
Portion A12, described cable core hole is stepped hole left small and right large and the length direction of through core rod, described protuberance
Shape fit with internal taper hole.Described protuberance stretches into and makes shape between protuberance and internal taper hole in internal taper hole
The extrusion passage A10 that beneficially extrusion molding stream is dynamic, the simultaneously shield bore of the cable core hole alignment die sleeve of core rod are become.Institute
Stating and be also shaped with blank pipe hole A23 on die sleeve, described blank pipe hole is parallel to a left side for the through die sleeve of shield bore and blank pipe hole
Side end face and the hole wall of internal taper hole；Meanwhile, the protuberance of described core rod is shaped with blank pipe bushing pipe A13, described sky
Tube lining pipe A13 is used for passing through blank pipe shield bore and being parallel to cable core hole, and the import of blank pipe bushing pipe is arranged on cable
On the step surface of core bore.
Described gradual change type cooler is for avoiding because being quenched the problem causing blank pipe size significantly to be shunk (due to sky
The intensity of pipe is poor, and the blank pipe of molding deforms contraction phase to relatively when the molten condition of high temperature is cooled to room temperature
Greatly).Described gradual change type cooler is more piece bosh (traditional bosh is single-unit) and each water saving
The water temperature of groove is the most different, and from extruder head to lead, the temperature of bosh is gradually lowered.
