Description
Technical field
The utility model relates to anticorrosion of a kind of crab-bolt, specifically, relates to a kind of crab-bolt anti-corrosive cover.
Background technique
Wind-powered electricity generation is another the new-generation industrial system produced in the power generation projects such as thermoelectricity, water power, nuclear power that continues.Wind power generating set is all run under lowered in field environment, and the situation that its field is run depends on natural environmental condition, and that is natural environmental condition has important impact to its operation conditions.Natural environmental condition comprises air pressure, temperature, humidity, typhoon, thunderbolt, dust storm, salt fog etc., and these environmental factors can cause erosion to each position of wind power tower, and then affect wind power generating set reliability of operation, Security and life-span.
Basis prestressed bolt assembly parts is mainly used in wind turbine tower basis and is connected with tower cylinder, is one of important component guaranteeing safety of structure.Natural environmental condition residing for wind turbine tower is severe, exposes aerial basic prestressed bolt and is easily corroded, cause potential safety hazard, thus needs to carry out the exsertion part of basic prestressed bolt anticorrosion with protection.Anticorrosion when dispatching from the factory of prestressed bolt in wind turbine tower basis is overall Dacroment process, but in installation process, the Dacroment corrosion-inhibiting coating of crab-bolt can be destroyed during fastening nut, have impact on antiseptic effect, reduce Security, increase the weight of later maintenance burden.
Model utility content
The technical problem that the utility model solves is to provide a kind of crab-bolt anti-corrosive cover, can improve the anticorrosion and protective value of basic prestressed bolt assembly parts, is not damaged by corrosion to guarantee crab-bolt can use safely under various natural environmental condition.
Technological scheme is as follows:
A kind of crab-bolt anti-corrosive cover, comprise anticorrosive casing pipe and band neck hexagon nut, the structure of described band neck hexagon nut comprises ring limit, nut body and ring cowling, and described ring limit and described ring cowling are separately positioned on described nut body two ends, and described nut body is provided with internal thread; Described anticorrosive casing pipe is tubular structure; The external diameter on described ring limit is less than the internal diameter of described anticorrosive casing pipe, and the external diameter of described ring cowling is greater than the external diameter of described nut body.
Further: described ring limit, described nut body and described ring cowling are concentric circle.
Further: the profile of described nut body is Hexagon.
Further: described ring limit is positioned at described anticorrosive casing pipe.
Compared with prior art, the utility model technique effect comprises:
The utility model can improve the anticorrosion and protective value of basic prestressed bolt assembly parts, is not damaged by corrosion to guarantee crab-bolt can use safely under various natural environmental condition.Band neck hexagon nut bottom of the present utility model is close to anchor slab and is tightened in crab-bolt, can infiltrate basis by anti-sealing from anchor hole; Anticorrosive casing pipe is enclosed within band neck hexagon nut simultaneously; the exposed part of crab-bolt between upper anchor slab and outer bottom flange all can be covered; various environmental impact factors to external world serve insulation blocking effect, effectively prevent the corrosion failure of crab-bolt, make the work that it is safer.The utility model is withstand voltage, shock-resistant, decay resistance is good, have good tensile strength, Applicable temperature scope-40 DEG C ~ 100 DEG C, working life can reach more than 15 years, meeting the requirement for anticorrosion of wind-driven generator tower frame completely, is a kind of anticorrosion component of excellent performance.

Embodiment
Below with reference to the accompanying drawings and preferred embodiment, technical solutions of the utility model are elaborated.
As shown in Figure 1, be the plan view of crab-bolt anti-corrosive cover in the utility model; As shown in Figure 2, be the plan view of crab-bolt anti-corrosive cover in the utility model.
Crab-bolt anti-corrosive cover comprises anticorrosive casing pipe 1 and band neck hexagon nut 2 on the whole, and wherein, band neck hexagon nut 2 is provided with internal thread; Anticorrosive casing pipe 1 is a thin-walled smooth cylindrical.During use, anticorrosive casing pipe 1 is sleeved in crab-bolt 3, then one end that band neck hexagon nut 2 is provided with ring limit 21 is tightened in crab-bolt 3 upward.
As shown in Figure 3, be the plan view with neck hexagon nut 2 in the utility model; As shown in Figure 4, be the left view with neck hexagon nut 2 in the utility model; As shown in Figure 5, be the plan view with neck hexagon nut 2 in the utility model.
Structure with neck hexagon nut 2 comprises ring limit 21, nut body 22, ring cowling 23, ring limit 21, nut body 22, ring cowling 23 are concentric circle, ring limit 21 and ring cowling 23 are separately positioned on nut body 22 two ends, the external diameter on ring limit 21 is less than the internal diameter of anticorrosive casing pipe 1, and the external diameter of ring cowling 23 is greater than the external diameter of nut body 22.
Nut body 22 is provided with internal thread, and profile is Hexagon, three channel floor casting once-throughs during production.
As shown in Figure 6, be the plan view of anticorrosive casing pipe in the utility model 1; As shown in Figure 7, be the plan view of anticorrosive casing pipe in the utility model 1.
Anticorrosive casing pipe 1 is tubular structure.
As shown in Figure 8, be the using state figure of crab-bolt anti-corrosive cover in the utility model; As shown in Figure 9, be the partial enlarged drawing of crab-bolt anti-corrosive cover in the utility model.
During use, on nut body 22 ring limit 21, outer wall smears special adhesive, again anticorrosive casing pipe 1 is connected with ring limit 21, then be enclosed within crab-bolt 3 with the downward entirety of the ring cowling 23 of nut body 22, fastening nut body 22, until the ring cowling 23 of nut body 22 compresses, by the space penetrated between upper anchor slab 4 and crab-bolt 3 suitable for reading for anticorrosive casing pipe 1 with upper anchor slab 4.
With neck hexagon nut 2 and anticorrosive casing pipe 1, crab-bolt 3 part between upper anchor slab 4 and external flanges 5 is covered completely, play the effect of crab-bolt corrosion-resistant.
