Description
(1) technical field
The present invention relates to the manufacturing installation of the member that a kind of cable-stayed bridge engineering uses, the bifilar helix that particularly relates to the HDPE cable sheath tube that a kind of steel strand stay cable the uses device that is extruded to shape.
(2) background technology
Steel strand stay cable is the lifeline of cable-stayed bridge.Large span stayed-cable bridge is because the suspension cable cable body is longer, and under the synergy of wind and rain, suspension cable can produce vibration, influences Structure Safety for Bridge.Therefore, the suspension cable that large span stayed-cable bridge is used is generally all taken measures on cable body, destroys the wind vibration frequency that causes inhaul cable vibration, with suppression of vibrations.Wind, rain and vibration resistance stay cable commonly used at present has two kinds of structural shapes: embossing drag-line and bifilar helix drag-line.The embossing drag-line is on the cable body surface pit of arranging according to certain rules to be set.The bifilar helix drag-line is the bifilar helix that projection is set on the cable body surface.Steel strand stay cable cable body anti-wind, rain and vibration mode is on the HDPE outer tube bifilar helix to be set.At present the manufacture method of double spiral HDPE pipe commonly used is: make the plastic extrusion die of band spiral type groove, be installed in mould on the extruding machine and mould can be rotated, directly make and be with protruding double spiral HDPE pipe.The shortcoming of this method is: plastic extrusion die length is long, and processed complex, cost are very high.Simultaneously, tubulation production line complex structure, the helix of projection is yielding.
(3) summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, the bifilar helix of the HDPE cable sheath tube of a kind of good product performance, the low cost of manufacture device that is extruded to shape is provided.
The object of the present invention is achieved like this: a kind of bifilar helix of HDPE cable sheath tube device that is extruded to shape, comprise stay pipe, toothed disc and positioning supporting frame, stay pipe is placed in outside the HDPE pipe, the stay pipe outer rim is provided with flange, toothed disc is arranged at outside the stay pipe, described positioning supporting frame has two, each one of front and back, be installed in the both sides, front and back of toothed disc respectively, each evenly installs three support wheels on every positioning supporting frame, be provided with groove in described support wheel outer rim, this groove matches with the flange of stay pipe outer rim setting, is used to support whole stay pipe.Toothed disc upper edge diametric(al) is symmetrically installed with the squeezing roller and the roller radiai adjustment device of two outer marginal zone grooves, described squeezing roller is installed on an end at the close HDPE pipe center of roller radiai adjustment device, and described toothed disc is by the pinion drive on belt and the reductor.
Adopt apparatus of the present invention, after the HDPE pipe is extruded, utilize the heat that himself carries, be made into double spiral HDPE pipe by fashion of extrusion.According to the hauling speed of HDPE pipe, the adjusted in concert squeezing roller can be produced stay-in-grade double-helix HDPE cable sheath tube along the axial rotary speed of HDPE pipe.
Apparatus of the present invention have the following advantages:
1, make full use of HDPE pipe self heat, energy savings, production cost is low.
2, bifilar helix on the HDPE pipe and the moulding of body basic synchronization, difficult drop-off, steady quality.
