Abstract
The utility model provides a zinc -nickel oozes layer preserved handle to be connected vicely, including a bolt and a nut, the bolt includes head and screw rod, the bolt with the nut surface is covered there is the coating, the layer is oozed for the zinc -nickel to the coating. The utility model overcomes the connection is vice among the prior art can not have resistant anticorrosion coating's up to standard defect when having stable torque coefficient to reach current there is easy landing in vice nut when the construction the defect of connecting.
Description
Technical field
The utility model relates to a kind of auxiliary connection, particularly a kind of marine with Zinc-nickel seeping layer preservative treatment auxiliary connection.
Background technique
Along with the wind-resources of inland wind-power electricity generation reduces gradually, current wind field is progressively to coastal and marine expansion, and coastal and marine environment is moister, salinity is also comparatively large, makes blower fan accessory requirement for anticorrosion also corresponding raising.The resistance to corrosion-inhibiting coating be widely used at present on auxiliary connection has galvanizing and Dacroment.Galvanizing antiseptic power is strong, and fastness is also relatively good, but its rough surface, and torque coefficient is unstable, the stretching method construction that spatial requirement generally can only be adopted large, and the calibrated wrench method construction that spatial requirement cannot be adopted little.And concerning Dacroment, although its antiseptic property reaches the neutral salt spray time of 720 ~ 1000 hours, to maritime environment, this standard is inadequate.Meanwhile, Dacroment is a kind of more fragile coating, have slight collide with namely can produce come off, and the high salt time-sharing environment in inapplicable sea.Therefore, for the high-strengt h joint at sea, its surface anticorrosion process, must reach high anti-corrosive properties, high anti-colliding with property, have stable torque coefficient simultaneously.
In addition, the nut surface be widely used at present in auxiliary connection is all flat surface, when using calibrated wrench method construction, there is the defect of easy landing.
Model utility content
The technical problems to be solved in the utility model can not have to overcome auxiliary connection in prior art the higher anticorrosion and defect of anti-coating of colliding with and the nut of existing auxiliary connection exist easy landing defect when constructing while having stable torque coefficient, provides a kind of Zinc-nickel seeping layer preservative treatment auxiliary connection.
The utility model solves above-mentioned technical problem by following technical proposals:
A kind of Zinc-nickel seeping layer preservative treatment auxiliary connection, comprise a bolt and a nut, described bolt comprises head and screw rod, and described bolt and described nut surface are covered with coating, and described coating is Zinc-nickel seeping layer.
Preferably, the surface of described nut is provided with groove vertically.
Preferably, described Zinc-nickel seeping layer preservative treatment auxiliary connection also comprises packing ring, and described gasket sleeve is located on described screw rod, and described washer face is covered with coating, and described coating is Zinc-nickel seeping layer.
Preferably, the shape of described groove is flat, rectangular.
Preferably, the quantity of described groove is 6.
Preferably, the quantity of described packing ring is two, and described two packing rings are all folded between the head of described bolt and described nut.
Preferably, the thickness of described coating is 40 ~ 60 μm.
Positive progressive effect of the present utility model is:
One, by scribbling Zinc-nickel seeping layer on bolt, nuts and washers surface, the limit of auxiliary connection anticorrosion time 1000 hours is breached, its neutral salt spray test >=2000 hour; Meet the requirement that torque coefficient standard deviation is no more than 0.01, the installation of convenient employing calibrated wrench method simultaneously.This Zinc-nickel seeping layer preservative treatment auxiliary connection also stands colliding with in transport and installation process simultaneously, ensure that and is not damaged with coating when installing before installing.
Two, by arranging groove on nut surface, increase surface drag, when using calibrated wrench method construction, nut is not easy landing.

Embodiment
Lift preferred embodiment below, and come by reference to the accompanying drawings clearlyer intactly the utility model to be described.
Understood incorporated by reference to Fig. 1, present embodiments provide a kind of Zinc-nickel seeping layer preservative treatment auxiliary connection, comprise bolt 1 and nut 2, described bolt 1 comprises head 11 and screw rod 12, and described bolt 1 and described nut 2 surface are covered with coating, and described coating is Zinc-nickel seeping layer.The thickness of described coating is 40 ~ 60 μm.
Described Zinc-nickel seeping layer preservative treatment auxiliary connection also comprises packing ring 3, and packing ring 3 is sheathed on described screw rod 12, and described packing ring 3 surface is covered with coating, and described coating is Zinc-nickel seeping layer.The quantity of packing ring 3 is two to reach optimum efficiency, but is not limited to two, and described two packing rings are all folded between the head 11 of bolt and nut 2.
The surface of described nut 2 is provided with groove 21 vertically, and the shape of described groove 21 is flat, rectangular, alternatively, also can be triangle.The quantity of described groove 21 is 3, can be 6 in other embodiments.
The manufacture method of the Zinc-nickel seeping layer preservative treatment auxiliary connection in the present embodiment is as follows:
One, the manufacture method of bolt: → shaping → heat treatment → rolled thread → Zinc-nickel seeping layer preservative treatment of getting the raw materials ready.
Two, the manufacture method of nut: → shaping → heat treatment → tapping → Zinc-nickel seeping layer preservative treatment of getting the raw materials ready.
Three, the manufacture method of packing ring: → shaping → heat treatment → Zinc-nickel seeping layer preservative treatment of getting the raw materials ready.
Described Zinc-nickel seeping layer preservative treatment coating processing side is Chongqing great You sufacing Co., Ltd.
Described Zinc-nickel seeping layer dominating process route is: alkali cleaning degreasing → ball blast → Zinc-nickel seeping layer → cooling → throwing ash wash ash → close.In alkali cleaning degreasing, require the complete oil-free of part surface, do drip test with water droplet, water droplet should scatter at once.In ball blast, do not allow part to have and leak throwing and floating ash, throw, then must do over again, be blown away by floating ash, will note shot quality simultaneously if any floating grey applying high voltage spray gun if any leakage, the conventional new shot of warp replaces old shot.Zinc-nickel seeping layer requires infiltration layer gray, uniform color, and without obvious aberration, surfacing evenly comes off without flaking.Throw ash and wash ash requirement clean for floating for surface ash process.Close and require without obvious attachment, without current mark, without holiday, without obvious aberration.
Zinc-nickel seeping layer preservative treatment auxiliary connection in the present embodiment meets the Attention problems requirement of wind power foundation, pylon, by scribbling Zinc-nickel seeping layer on bolt, nuts and washers surface, make described Zinc-nickel seeping layer preservative treatment auxiliary connection while having stable torque coefficient, have higher anticorrosion and anti-performance of colliding with; Meanwhile, by arranging groove on nut surface, increase surface drag, when using calibrated wrench method construction, nut is not easy landing.
Although the foregoing describe embodiment of the present utility model, it will be understood by those of skill in the art that this only illustrates, protection domain of the present utility model is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present utility model and essence, can make various changes or modifications to these mode of executions, but these change and amendment all falls into protection domain of the present utility model.
