Description
Technical field
The utility model is related to a kind of drag-line, it is more particularly to a kind of can the compound sealing type oblique pull substituted of single steel strand
Rope.
Background technology
At present at home, the suspension cable of large span, using it is most be steel strand wires suspension cable because bridge all compares
Greatly, project cost is corresponding also higher, and the design life of bridge is long, and general service life is all at 50 years or more.And
During the operation of entire bridge, as the main stressed member of bridge, suspension cable is within the regular hour, according to bridge inspection and maintenance
Requirement, need to replace drag-line, generally be needed replacing at 15 years or so primary.Some suspension cables are because anchorage sealing is lost
Effect, steel strand wires seriously corroded, the period of replacement are shorter.
In the suspension cable built in recent years, there are mainly two types of the anchorage corrosion protection structures of suspension cable, and one kind is to penetrating anchorage
Steel strand wires inside sealing drum carry out epoxy filling and carry out anti-corrosion, the epoxy resin that can be solidified are perfused in sealing bucket, by whole beam
Steel strand wires are cast into a whole anti-corrosion, as shown in Figure 1.The anti-corrosion effect of which is general, is alternately influenced by cold and hot,
Cured epoxy resin is it is possible that can crack, once cracking, extraneous corrosive medium, as the rainwater anchor head internal corrosion steel that can enter twists
Line, also, steel strand wires be all by epoxy resin cure into an entirety, it is very inconvenient when stay cable replacing, need
It seals bridge to be replaced, seriously affects traffic.
Another commonly used Stay Cable Anchors structure is as follows, and the structure of anchorage is similar with the first, in sealing drum
Portion's perfusion is anti-corrosion grease, as shown in Figure 2.This anchorage lays down the power of steel strand wires when steel strand wires are needed replacing
After, substituting for single steel strand can be carried out.But the anchorage of this structure, which is poured in internal anti-corrosion grease, to be solidified, with
The variation of temperature, can be expanded with heat and contract with cold, is caused stress in anchorage sealing drum, is easily spilt from anchorage end, and is being taken out
The steel strand wires that the anti-corrosion grease being perfused in sealing drum during changing can constantly be substituted are brought out, and it is oil entirely entirely to substitute process
Dirt, very dirty, contamination very severe.
Invention content
The technical problems to be solved in the utility model is：There is provided a kind of installation and replacement it is more convenient, it is environmentally friendly can be single
The compound sealing type suspension cable that steel strand wires are substituted, which uses double sealing structure, favorable anti-corrosion effect, and substitutes steel strand wires
When working environment it is good, solve the above-mentioned problems of the prior art.
Solving the technical solution of above-mentioned technical problem is：It is a kind of can the compound sealing type suspension cable substituted of single steel strand,
Two anchorages including guy of twisted steel cable and mounted on guy of twisted steel cable both ends, the anchorage include protective cover, intermediate plate, spiral shell
Mother, anchor slab, sealing drum, sealing device and the turnbuckle being connect with sealing device, the protective cover are mounted on nut, spiral shell
Mother is mounted on anchor slab, and anchor slab is connect with sealing drum, and clip plate is equipped in sealing drum, and drawing is provided between anchor slab and clip plate
Tight bolt provided pipe, encapsulating provided pipe and the HDPE pipes passed through for steel strand wires, the interior perfusion of sealing drum between anchor slab and clip plate
There is high-strength cement, the turnbuckle through-hole connected with turnbuckle provided pipe is had on anchor slab, is connected with encapsulating provided pipe
Encapsulating through-hole and the steel strand wires through-hole that is connected with HDPE pipes, the sealing device sealing drum is mounted on by turnbuckle
It is interior, fluid sealant cavity is formed between sealing device and clip plate, fluid sealant cavity connects respectively with encapsulating provided pipe, HDPE pipes,
Steel strand wires are extended to after passing through sealing device, HDPE pipes and anchor slab in protective cover, and steel strand wires are fixed on by intermediate plate on anchor slab, institute
It is filled between encapsulating provided pipe, fluid sealant cavity, HDPE pipes and the steel strand wires stated, between steel strand wires through-hole and steel strand wires poly-
Urethane fluid sealant.
The sealing device includes pressing plate, sealed rubber plate and sealing plate I, sealing plate II, the pressing plate, sealing rubber
Steel strand wires are provided on offset plate and sealing plate I, sealing plate II and penetrate hole, sealed rubber plate be located at sealing plate I and sealing plate II it
Between, round ring boss is both provided in the both ends of the surface of sealed rubber plate, sealing plate I, sealing with two end in contact of sealed rubber plate
Boss limiting inclined hole is provided on II end face of plate, boss limiting inclined hole and the steel strand wires of sealing plate I, sealing plate II penetrate Kong Lian
Logical, the turnbuckle passes through sealing plate I, sealed rubber plate, sealing plate II to be connect with pressing plate, when tightening turnbuckle,
The round ring boss, which is located in boss limiting inclined hole, compresses steel strand wires sealing.
I edge of sealing plate is additionally provided with position limiting convex ring.
It is big end towards the bellmouth in the middle part of drag-line that the steel strand wires being provided on pressing plate, which penetrate hole,.
Due to the adoption of the above technical scheme, the utility model has the advantages that：
1st, installation and replacement are more convenient, environmentally friendly.When needing to substitute steel strand wires, protective cover is removed, by the anti-corrosion of smearing
Grease is wiped clean, and steel strand wires power is laid down, it is possible to carry out the single polyurethane sealant substituted, be perfused before, Bu Huihe
Steel strand wires are frozen into a very hard entirety, and polyurethane sealant is a kind of commonly used flexible glue, hardness and rubber after solidification
Hardness is similar and the caking property of steel strand wires will not be very strong, but can meet sealing performance.So when steel strand wires are substituted
It waits, it is only necessary to the power of very little, it is possible to which steel strand wires are released inside anchorage sealing drum.And substitute steel strand wires process will not band
Go out greasy dirt, working environment is good.
2nd, using dual compound seal, it is effectively increased anti-corrosion effect.It is dual that steel strand wires, which need corrosion-resistant position,
Under the conditions of anti-corrosion measure, anti-corrosion effect is effectively raised, increases the service life of drag-line, and reduces operation difficulty.
3rd, anchorage is just assembled in engineering, and perfusion cost reserves steel strand wires than relatively low high-strength cement in sealing drum
Autonomous channel does not need to that a large amount of epoxy resin mortar or anti-corrosion grease is perfused in sealing drum, reduces the processing cost of anchorage.
In the following, in conjunction with the accompanying drawings and embodiments to the utility model it is a kind of can the compound sealing type substituted of single steel strand it is oblique
The technical characteristic of drag-line is further described.
