Abstract
The utility model relates to a protective sleeve of a pulling cable. The protective sleeve of the utility model comprises a cylindrical sleeve barrel 1, the inside of which is sheathed with a plurality of circular guide tubes 3, light filling 3 like polyurethane foaming plastics is filled between the cylindrical sleeve barrel 1 and the circular guide tubes 3, both ends of the cylindrical sleeve barrel 1 are respectively provided with an isolating plate 4, and steel stranded wires 5 penetrate into the circular guide tubes 3. The protective sleeve of a pulling cable of the utility model has the advantages of light weight, convenient installation and replacement of a single cable.
Description
The utility model relates to a kind of protective sleeve of pulling cable, particularly the steel strand protective jacket.
At present, anticorrosion for steel strand, it is general that use is tubular sheath (referring to Fig. 1), this kind jacket structure is simple, in actual use, after reeving, be in the milk, because the density of grouting agent is bigger, the load of whole bridge is increased, and it is big that the amount of deflection of single rope becomes, and can't realize the single rope that changes.
The purpose of this utility model is to provide a kind of light weight, easy for installation, the protective sleeve of pulling cable that can singlely change rope.
For reaching above-mentioned purpose, protective sleeve of pulling cable of the present utility model comprises the tubular sleeve, in the tubular sleeve, be with a plurality of circular guide pipes, between tubular sleeve and circular guide pipe, be filled with light filler, the tubular sleeve respectively has a division board in the two ends, one of circular guide pipe end diameter is big slightly, with convenient two sections butt joints.
Owing to adopt said structure, the utlity model has light weight, easy for installation, the advantage that can singlely change rope.
Below, the architectural feature to the protective sleeve of pulling cable of the utility model is described further in conjunction with the accompanying drawings and embodiments.
Fig. 1: existing tubular jacket structure schematic diagram;
Fig. 2: the utility model protective sleeve of pulling cable structural representation.
Embodiment
A kind of protective sleeve of pulling cable.As shown in Figure 2, this sheath comprises tubular sleeve 1, in tubular sleeve 1, be with a plurality of circular guide pipes 3, between tubular sleeve 1 and circular guide pipe 3, be filled with light filler 2 as polyurethane foam plastics and so on, one division board 4 is respectively arranged in tubular sleeve 1 two ends, steel strand penetrate in the circular guide pipe 3, and described circular guide pipe 3 one end diameters are big slightly.
Among Fig. 1,1, the PE sheath, 5, guy of twisted steel cable, 6, cement mortar.
The utility model product be a kind of can field erected product, hang rope at the needs drag-line and execute man-hour, on ground tubular sleeve 1 one joints of sheath are assembled with another joint earlier, the little end of diameter in the circular guide pipe 3 of one joint in the sheath is inserted the big slightly end of diameter in the circular guide pipe 3 in another joint sheath, with welding equipment that 1 butt welding of tubular sleeve is firm then, the repeatedly circulation of more than working is when reaching Len req, with hanging device it is winched to the installation site, reeve then.
In use, when quality problems appear in certain root steel strand, can carry out the single rope that changes, promptly put a former steel strand of taking-up, wear new steel strand again it.
