Abstract
The invention relates to a tapered protecting sleeve connected with a scattered rope sling to prevent a main cable from rustiness. The tapered protecting sleeve comprises an upper half tapered protecting steel plate and a lower half tapered protecting steel plate which can be spliced and fixed into a taper, wherein a drainage hole is formed at the bottom of the lower half tapered protecting steel plate; the tip of the taper formed by the upper half tapered protecting steel plate and the lower half tapered protecting steel plate is connected with the scattered rope sling; a steel plate matched with a port is arranged at an opening at the other end of the taper; and a plurality of branch cable open holes are formed in the steel plate. The upper half tapered protecting steel plate and the lower half tapered protecting steel plate which can be spliced and fixed into the taper are adopted, the tip of the taper is connected with the scattered rope sling, and the drainage hole is formed at the bottom of the lower half tapered protecting steel plate, so that the rustiness of a main cable and branch cables due to water accumulation in the scattered rope sling can be avoided. Since the steel plate is fixed at one end of the taper, and the branch cable open holes are formed in the steel plate, the ingress of the branch cables can be facilitated.
Description
Technical field
The invention belongs to the antirust field of cable, be specifically related to a kind of taper protective jacket that loose noose prevention main push-towing rope gets rusty that is connected.
Background technology
Due to the needs of anchoring, main push-towing rope need to scatter when approaching king-tower, but at present domestic only with loose noose dispersion strand, causes loose noose stressed larger; Loose noose to loose rope anchored end only has a bit of rain cover, causes this section Suo Rong easy-to-rust that falls apart; The loose rope of loose noose upstream port is intensive, easily builds up rainwater and cause faling apart rope and main push-towing rope corrosion, and current domestic shortage is carried out the equipment of special protection to this section minute cable.
At present, there are the following problems on domestic market, only to use loose noose to disperse main push-towing rope: (1) loose noose to anchored end only has a bit of rain cover, causes in this section of loose rope exposure air easily corrosion; (2) the too small loose rope in loose cross section, noose upstream is intensive, causes this to locate easy ponding, easily loose noose and main push-towing rope is carried out to corrosion.
Because above these problems cause the easy corrosion of minute cable, the loose easy ponding of noose upstream port, corrosive gas is easy to invade main push-towing rope inside, also can cause loose noose and main push-towing rope corrosion, and loose noose is stressed larger, affects the service life of main push-towing rope and loose noose.
Summary of the invention
The object of the invention is to overcome the shortcoming existing in above-mentioned prior art, a kind of taper protective jacket that loose noose prevention main push-towing rope gets rusty that is connected is provided, have and can protect minute cable not to be subject to corrosion, the advantage that extends the application life of cable.
For achieving the above object, the present invention by the following technical solutions: comprise and can splice upper half-cone shoulder guard and the lower half-cone shoulder guard that is fixed into cone, and the bottom of lower half-cone shoulder guard offers drain hole;
The most advanced and sophisticated noose that falls apart that is connected of cone that described upper half-cone shoulder guard forms with lower half-cone shoulder guard, cone other end opening part is provided with the steel plate matching with port, and on steel plate, offers cable perforate in some minutes.
Between described upper half-cone shoulder guard and lower half-cone shoulder guard, by some connecting bolts, fix, and connect gap through being welded and fixed.
Described connecting bolt is positioned at the both sides of cone, and is symmetrical arranged along the axis of cone.
Described drain hole is opened in the most advanced and sophisticated centre of lower half-cone shoulder guard.
Between described cone tip and loose noose, seam crossing is used sealing compound that both are sealed.
Minute cable perforate arranging on described steel plate is indent circular groove.
A described minute cable perforate arranges in groups.
In described minute cable perforate, be fixed with a minute cable wrap of being close to hole wall and wrap up in steel, and divide a cable wrap to wrap up in steel one end and extend cone.
Between described steel plate and cone, for being welded and fixed, and be filled with sealing compound in gap.
The present invention has following beneficial effect: the prior art of comparing, the present invention can splice by arranging upper half-cone shoulder guard and the lower half-cone shoulder guard that is fixed into cone, cone is most advanced and sophisticated connects loose noose, and the bottom of lower half-cone shoulder guard offers drain hole; Thereby can prevent the main push-towing rope and minute cable corrosion that due to loose noose internal water accumulation, cause.Because cone one end is fixed with steel plate, and on steel plate, offer a minute cable perforate, thereby can conveniently divide cable to enter.
Further, owing to fixing and being welded and fixed by some connecting bolts between upper half-cone shoulder guard and lower half-cone shoulder guard, thereby guarantee the effect sealing, improved the protection effect of device.
Further, because minute cable perforate arranging on steel plate is indent circular groove, thereby be convenient to the protection needs that minute cable and cable overlap junction.
Further, owing to being fixed with a minute cable wrap in minute cable perforate, wrap up in steel pipe, thereby be convenient to the access of minute cable.

The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Referring to Fig. 1-6, the present invention includes and can splice upper half-cone shoulder guard 4 and the lower half-cone shoulder guard 5 that is fixed into cone, and the most advanced and sophisticated centre bottom of lower half-cone shoulder guard 5 offers drain hole 7, upper half-cone shoulder guard 4 and lower half-cone shoulder guard 5 are fixed and are welded and fixed by some connecting bolts 11, the most advanced and sophisticated noose 8 that falls apart that connects of cone forming, and seam crossing is used sealing compound 6 by both sealings, connecting bolt 11 is positioned at the both sides of cone, and the axis along cone is symmetrical arranged, cone other end opening part is provided with the steel plate 2 matching with port through being welded and fixed, and in gap, be filled with sealing compound 6, on steel plate 2, offer minute cable perforate 10 of some indent circular grooves, and a minute cable perforate 10 arranges in groups, in minute cable perforate 10, be fixed with a minute cable wrap of being close to hole wall and wrap up in steel pipe 1, and a minute cable wrap is wrapped up in steel pipe 1 one end and is extended cone.
During installation, first taper protective jacket is transported to tower top, and then is transported to installation site along main push-towing rope, first install half-cone protective jacket, more lower half-cone protective jacket is winched to main push-towing rope one side.Then from main push-towing rope opposite side, put down lifting rope, then hang the lower half-cone protective jacket of liter, itself and upper half-cone protective jacket are closed up, upper and lower taper shoulder guard is used bolt to connect, and seam is passed through welded seal.After taper protective jacket is in place, according to minute cable projection perforate coordinate is revised on steel plate, then Plate Welding is merged, the gap between taper protective jacket and loose noose is filled up by sealing compound.After above operation completes, use steel plate by drain hole welded seal, then by steel plate aperture, in taper protective jacket, pour into sealing compound, whole taper protective jacket installs.
