Description
Technical field
The invention belongs to pipe technology field, especially relate to a kind of shaped device of self-bearing type air-blowing pipeline.
Background technology
Along with the develop rapidly of the industries such as electric power, communication, the amount of laying of cable is more and more, and on the one hand, because in the past a large amount of cables adopts built on stilts laying, therefore, aerial cable is very in disorder, has affected city look and feel, meanwhile, has brought great potential safety hazard; For this reason, country has promulgated corresponding law, rules and instruction, need to adopt into the mode on ground and lay for cable.Cable mainly contains poling and direct-buried mode in underground laying, and direct-buried mode need to be dug ground, and needs multiple tracks examination and approval procedures, therefore, cumbersome; For this reason, pipeline laying mode will be after the principal mode of underground laying.
In the underground larger caliber pipeline having laid, the cable of and smooth in appearance less for diameter, while having sufficient space in pipeline, can directly carry out tractive lays, but, tractive cable laying operation progress affects the quality of cable more slowly and easily, especially optical cable, once the quality of cable is impaired in construction, just very huge by the cost of cable taking-up or restorability.
For larger city, existing cable pipeline resource pretty nervous, rents the pipeline of the about 18mm diameter of 1KM conventionally, and annual price is 200,000 yuan of left and right, therefore, quite expensive; Nonetheless, also have the Ji Fei operator of operator in a lot of areas because renting the progress that affects engineering less than conduit resource, what even have can only abandon original engineering.
On the other hand, China relatively payes attention to the construction of plumbing, blow-off line, and the resource of this class underground piping is abundanter, needs further develop and rationally utilize.
In addition, in existing built on stilts system of laying, for existing cable, can only lay separately, by cable fixing mode one by one, this mode has obviously caused the in disorder of circuit and has increased cost, affected The Surroundings in Cities.
For this reason, in industry, expect to there is good solution, can, at the underground pipeline that has excess room, especially in the pipeline such as rainwater, sewage, carry out laying of cable; And expect better solution, for the aerial cable laying later, plan, make city more attractive in appearance, and speed of application and progress faster.
?yet the problem that the self-bearing type air-blowing pipeline of manufacturing in prior art often exists dowel to tilt, has not only affected outward appearance, and has affected the quality of self-bearing type air-blowing pipeline, has caused more trouble to construction.
Summary of the invention
In order to address the above problem, the object of the invention is to disclose a kind of shaped device of self-bearing type air-blowing pipeline, and disclose the method that adopts this device to make the moulding of self-bearing type air-blowing pipeline, they are realized by the following technical solutions.
A kind of shaped device of self-bearing type air-blowing pipeline, it includes the extrusion head 21 being arranged on extrusion molding fuselage 22, the bosh 31 being supported by tank supporter 32, extrusion molding fuselage is supported by extruding machine support component 23, on extrusion head, there is reinforcement hole 111 and inner tube via hole 121, bosh is positioned at the front end of extrusion head, and reinforcement hole and inner tube via hole are to connect extrusion head, it is characterized in that in bosh, thering are at least two pairs of shaping mechanisms, the every pair of moulding structure machine is oppositely arranged by two and highly relatively consistent positioner forms, each positioner is by shaping rack 42, turning cylinder 41, connecting rod 43 forms, shaping rack comprises and holds outer tube slot 421, hold muscle post 422, hold self-supporting body groove 423, upper limit post 424, lower limit post 425, hold outer tube slot at lower limit post and hold between muscle post, hold self-supporting body groove at upper limit post and hold between muscle post, hold muscle post, upper limit post, lower limit post is all cylindrical and has identical external diameter and the axis coinciding, from upper limit post upper surface, to lower limit post lower surface, there is the axis hole 426 of perforation, appearance outer tube slot is annular groove, holding self-supporting body groove is also annular groove, the radius of curvature of holding outer tube slot is greater than the radius of curvature of holding self-supporting body groove, hold outer tube slot and hold self-supporting body groove and do not communicate with axis hole, turning cylinder passes axis hole and can make shaping rack relatively rotate axle and is rotated, and the two ends of turning cylinder are connected with connecting rod, and connecting rod is fixed on the sidewall of bosh.
