Description
The utility model relates to a kind of bridge cable protector, especially relates to a kind of guy of twisted steel cable protector of Cable stayed bridge.
In the prior art, the guy system of Cable stayed bridge is made up of the syndeton of drag-line, protection mechanism, ground tackle, ground tackle and Liang Heta etc., and drag-line can constitute with parallel high-strength steel wire or twisted wire.The quality of protection mechanism directly influences the application life of Cable stayed bridge, and therefore, it is an indispensable part in the guy system.So far the state-of-the-art safeguard structure that is used for guy system for bridge is in factory single steel strand to be carried out multilayer proofing earlier, in the building site these parallel steel stranded wire bundles penetrated outer tube then, form the space of a sealing, not only the fixing mutual alignment between the steel wire bundle but also its in addition certain protection; To the steel wire bundle in the ground tackle part also is to protect by form each enclosed construction between main group anchor, stiffener, capping and beam.Its weak point is: be difficult to it is carried out examination and maintenance.Owing to reasons such as climate temperature change, sealing is not close, tend between steel strand and outer tube, produce moisture and moisture in the enclosed construction of ground tackle part, influence the life-span of steel strand; So, must often check and remove moisture and moisture to it.But existing protection mechanism then is difficult to carry out necessary inspection and remove moisture and the work of moisture.In addition, in snowy winter, wind and snow can produce bigger influence to the life-span of drag-line, may occur the wind and snow exciting phenomenon of drag-line when serious, and prior art does not also have and can solve well this problem.
The purpose of this utility model just provides and a kind ofly can remove the moisture that produces in each enclosed construction of outer tube and ground tackle part and the bridge cable protector of moisture effectively.
By further improvement, also can realize another purpose of the present utility model: just provide a kind of bridge cable protector that can remove moisture automatically, make it to keep dry according to the humidity of steel strand.
For realizing above-mentioned first purpose, the utility model can be taked following technical measures:
Guy protector of the present utility model comprises the outer tube of drag-line and each enclosed construction of ground tackle part, and it is characterized in that: this device also comprises a dry-air blast unit; Between described drag-line outer tube and each enclosed construction, the air vent that is interconnected is arranged; On the enclosed construction that is communicated with, have air intake vent and air outlet; Wherein, air intake vent is connected with the dry-air blast unit, and air outlet then leads to the external world.
Because the trend that the respectively oriented next part neutralization of moisture in the drag-line enclosure space and moisture laden air is upwards concentrated, therefore, after the technical measures more than having taked, start the dry-air blast unit, dry air enters the enclosed construction of connection from air intake vent, moisture is drained from air outlet, can effectively remove the moisture that produces in outer tube and each enclosed construction like this and keep its drying.
The utility model can also be installed discharging valve at the minimum position of lasso protection enclosure space.If the enclosure space of drag-line has moisture, they will concentrate the discharging valve that flows to minimum point downwards, be discharged by the maintenance personnel.
Each enclosed construction described in the utility model comprises that (1) is from the anchor slab of tower inhaul main group anchor to stiffener with the enclosure space that surrounds of protective cover plate; (2) enclosure space that forms respectively by tower conduit, outer tube, beam conduit; (3) enclosure space that stiffener and protective cover plate surround in the beam.
The utility model is on the basis of above-mentioned guy protector, following form can also be arranged: it has an ajutage that runs through its each enclosed construction along drag-line, one end and air intake vent join, air intake vent and air outlet all are arranged on the anchor slab of main group anchor, can establish several air outlets on ajutage is communicated with each protection enclosure space of drag-line respectively, make dry air can directly enter each enclosure space, further improve dehumidifying speed and effect.
The utility model on the basis of aforesaid guy protector, can be set up a dehumidifier unit in order further to increase protection effect, and dehumidifier unit and air outlet join.The dehumidifier unit with and the dry-air blast unit form the drying and watering cycle unit, remove the moisture that produces in outer tube and each enclosed construction and also keep its dry better effects if.
For realizing second goal of the invention of the present utility model, in the circuit control system of the dry-air blast unit of aforesaid guy protector and dehumidifier unit, set up an automatic feedback control device; In the enclosed construction at drag-line bottom and top, be provided with steel strand test specimen humidity auto-measuring point and device; Measuring equipment has control line to link to each other with automatic feedback control system.
Measure steel strand test specimen humidity when overproof when measuring device, the automatic feedback control device starts dry-air blast unit and dehumidifier unit, the dehumidifier of blowing automatically.
The utility model has the advantages that:
1) visibility of lasso protection structure, degree of controllability, degree and reliability all are higher than prior art as can be known;
2) be convenient to the replacing of single steel strand;
3) can simplify the multilayer proofing of single steel strand, for example need only zinc-platedly get final product.
4) if the dry-air blast machine in the drying and watering cycle unit blasts hot air, can melt the ice and snow that is amassed on the drag-line outer tube, thoroughly solve the problem of drag-line wind and snow exciting.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
