Abstract
The utility model relates to a wind and rain exciting preventing screw rib pulling rope, comprising a rope body 1. The wind and rain exciting preventing screw rib pulling rope is characterized in that: the outer surface of the rope body is wound with a cylindrical screw rib 2. Thus, the waterline generation of the pulling rope can be broken and weakened and the wind and rain exciting mechanism can be prevented happening; the possibility of the generation of the wind and rain excitation of the pulling rope can be eliminated fundamentally.
Description
Technical field:
The utility model relates to a kind of anti-wind, rain and vibration spiral bar drag-line that is used for science of bridge building.
Background technology:
At present, drag-line generally all is to adopt half parallel galvanized steel rope outsourcing pe sheath to protect.Therefore the outer surface of this drag-line is smooth cylindrical, and drag-line can be subjected to effect generation vibrations by a relatively large margin such as wind and rain.The vibration of drag-line can cause the steel wire in the drag-line to produce additional flexural stress, thereby quickens the fatigue of drag-line, reduces the service life of drag-line and brings the psychological sense of insecurity of user.Especially on large span stayed-cable bridge, show particularly outstandingly.In order to slow down the vibration of drag-line, existing drag-line has all been installed damping shock absorber or oil-pressure damper at its two ends.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of anti-wind, rain and vibration spiral bar drag-line of energy anti-wind, rain and vibration is provided.
The purpose of this utility model is achieved in that a kind of anti-wind, rain and vibration spiral bar drag-line, comprises cable body, is characterized in being wound with on the cable body outer surface cylindrical spiral bar.Can destroy or weaken the mechanism that drag-line generates waterline and rain wind induced vibration takes place like this, fundamentally eliminate the possibility of drag-line generation rain wind induced vibration.
Description of drawings:
Fig. 1 is a general structure schematic diagram of the present utility model.
Fig. 2 is that the A-A of Fig. 1 amplifies cut-away view.
The specific embodiment:
As Fig. 1～2, the utility model is a kind of anti-wind, rain and vibration spiral bar drag-line.Mainly form by cable body 1 and cylindrical spiral bar 2 two parts.Cable body 1 forms cylindrical outer surface by steel tendon outer surface hot extruded polyethylene.Twining pitch on cable body 1 outer surface is 6 times of cylindrical spiral bars 2 to 10 times of drag-line diameters.
Claims (2)
1, a kind of anti-wind, rain and vibration spiral bar drag-line comprises cable body (1), it is characterized in that cable body (1) outer surface twines cylindrical spiral bar (2).
2, a kind of anti-wind, rain and vibration spiral bar drag-line according to claim 1, the pitch that it is characterized in that cylindrical spiral bar is 6 times of diameters to 10 times of drag-lines.
