Abstract
A technology for preparing the spiral rib on the jacket of a diagonal cable in order to resist against wind, rain and vibration includes such steps as making rib bar with the material same as the protecting jacket of diagonal cable, winding it on a reel, installing a winding unit able to revolute round said cable to the output position of an extruder for extruding said protecting jacket, extruding the fused PE onto the surface of said cable while sticking said rib bar onto the surface of protecting jacket, and continuous extruding while revoluting said winding unit to form a spiral rib.
Description
Technical field
The present invention relates to a kind of method of making the aerodynamics vibration reducing measure that is applicable on the parallel wire stay surface of bridge construction engineering.
Background technology
Parallel wire stay is the key member that is applied to the bridge construction engineering structure, its structure as shown in Figure 1, drag-line inside is steel wire 1 ', and formalize by band 2 ' colligation, extrude high density polyethylene (HDPE) (PE) sheath 3 ' more outside and play the antisepsis of parallel steel wire rope, the cross section profile of drag-line is circular, and the PE jacket surface is comparatively smooth.Show that after deliberation the drag-line with circular cross-section and smooth surface descends in the acting in conjunction of wind and rain, cause significantly vibration, i.e. rain wind induced vibration easily.Suppressing the most effective way of drag-line rain wind induced vibration at present is to take the aerodynamics vibration reducing measure, the aerodynamics vibration reducing measure is meant and changes original smooth surface and the circular cable body of drag-line, to destroy the necessary condition that forms rain wind induced vibration: the motion waterline on drag-line surface.As the polygon cable body, longitudinal rib is offered on the cable body surface, and pit is beaten on cable body surface, and cable body surface spiral twines rib, and it is first-class that the sleeve pipe that the making outer surface has a screw line is installed on drag-line again.Be a kind of comparatively effective measures wherein at drag-line surface winding screw rib, spiral rib 4 ' as shown in Figure 2, but the winding screw rib need carry out after construction and installation finish in the bridge construction at drag-line, and will make the special-purpose plant such as car of climbing in the air, wastes time and energy.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can effectively overcome above-mentioned defective, drag-line is extruded in factory in the PE sheath, finish the preparation method of the stayed-cable screw line anti-wind and rain and vibration means that jacket surface screw line rib makes.
To achieve these goals, the technical solution adopted in the present invention is: a kind of preparation method of stayed-cable screw line anti-wind and rain and vibration means mainly may further comprise the steps: a. makes rib with the homogeneous material of protective sleeve of pulling cable in advance, and rolling is on drum; B. being equipped with in the exit position that drag-line extrudes the extruder head of PE sheath that power set drive can be around the rotation of drag-line center, and is provided with the wind of the rotating shaft that drum can be installed; C. extrude after on the cable body as the PE of fusion, rib is bonded at jacket surface, make sheath and the combination of rib hot melt, d. start the drive unit of wind simultaneously, make the wind rotation, drive the drum rotation that is installed in the rotating shaft, drag-line straight line after extruding the PE sheath moves ahead, rib is that the center rotation is twined with the drag-line, thereby forms the rib that spiral twines on drag-line.
In the above-mentioned scheme, reach requirement, can regulate the hauling speed of wind rotating speed and wire digging line for the spiral of regulating rib twines pitch; For regulating rib at protective sleeve of pulling cable rat height, can friction or calutron be set in the rotating shaft that drum is installed, with the rotational resistance of adjusting drum, thus the winding tension of adjusting rib, and then regulate the height of projection of rib on the protective sleeve of pulling cable surface; The rotating shaft that drum can be installed on wind can be provided with a plurality of, can make the spiral rib with bull on the protective sleeve of pulling cable surface like this.
Owing to adopt such scheme, be not difficult to draw as drawing a conclusion, the present invention is skillfully constructed, it has solved drag-line is made the spiral rib in factory technical barrier, twine with spiral at the construction field (site) and to compare, lacked operation procedure, more can control screw pitch, and no longer need with clip the spiral rib be fixed on the drag-line surface every certain-length by motorisation unit.
Below in conjunction with drawings and Examples the present invention is described in further detail.
Description of drawings
Fig. 1 is not for taking the common parallel wire stay cross section structure figure of aerodynamics vibration reducing measure.
Fig. 2 is a schematic diagram of having taked spiral rib aerodynamics vibration reducing measure.
Fig. 3 is a schematic cross-section of taking twin-feed spiral rib aerodynamics vibration reducing measure
Fig. 4, Fig. 5 are the operation schematic diagram of one embodiment of the invention.
The specific embodiment
See Fig. 4, shown in Figure 5, wind 1 is installed in the anterior locations of extruder head export department 2, motor 8, decelerator 7, pinion 6, gear wheel 5, bearing 16, rotating disk 15 constitute drive unit, and for ease of operation, drive unit is installed on the frame 9 that can move forward and backward.Become the protective sleeve of pulling cable 3 of molten condition to be extruded and to be coated on the wire digging line 4 from head export department 2.Rib 11 rolling of making of protective sleeve of pulling cable 3 same material in advance is can be on the drum 10 that axle 12 freely rotates, on 12 bearing 17 that are installed on the rotating disk 15.
The course of work: wire digging line 4 is pulled forward with certain speed and advances, and sheath 3 is extruded from head export department 2 and is coated on the wire digging line 4; Start drive unit, with the end of a thread 11a, the 11b of rib by surface at the sheath 3 that is in the condition of high temperature, the end of a thread 11a, the 11b of rib and sheath 3 through overheated melt combine after, wire digging line advance and the drive of dial rotation under, rib 11 begins to be spirally wound on the wire digging line 4 that has coated sheath, under continuous operation, the drag-line surface has just made the spiral rib.What present embodiment was made is the rib of twin-feed spiral.
Be the screw pitch requirement of the rib of regulating different drag-lines, can regulate the rotating speed of drive unit and the hauling speed of wire digging line and realize.
By regulating friction, can regulate the skin-friction force that is installed in the frictional disk 13 on the axle 12, thereby regulate the winding tension of rib 11a, 11b, and then regulate the height of projection of rib on the protective sleeve of pulling cable surface with 14 tension force.
