Abstract
The invention relates to a quick connecting positioning device for a flange screw hole between sections at the on-site hoisting moment of a tower cylinder of a large-size wind generating set and belongs to the technical field of equipment mounting of the large-size wind generating set. The quick connecting positioning device is characterized in that: an opening swelling tapered sleeve is arranged in the flange screw hole of a tower cylinder flange; the opening swelling tapered sleeve is aligned with an inner plane of the tower cylinder flange; a tapered positioning shaft is mounted according to the tapered direction of the opening swelling tapered sleeve; and then a gasket and a locking nut are assembled and are used for fastening, so that the quick connecting positioning device is formed. The quick connecting positioning device provided by the invention has the advantages of simple structure, small volume, capability of quickly swelling, guiding and positioning and convenience in detaching.
Description
One, technical field
The present invention relates to the quick connection locator of flange screw between a kind of Large-scale Wind Turbines tower cylinder on-site hoisting period and the section, belong to Large-scale Wind Turbines equipment mounting technique field.
Two, technical background
The tower cylinder part of the wind power generating set that present 600KW is above, its main structure is comprised of foundation ring (base), tower cylinder hypomere, tower cylinder stage casing (or several joints stage casing), tower cylinder epimere, the two ends of every section tower cylinder all are welded with the large diameter many bolts hole flange of a slice, installation between tower cylinder section and the section is by the large tonnage crane lifting, is connected and fixed by high-strength bolt to form behind many bolts hole location again.Erection sequence is: 1. first with tower cylinder hypomere lifting, all bolts hole on the tower cylinder hypomere lower flange are located one by one with casting solidification all bolts hole on underground foundation ring (base) upper flange, be connected and fixed by high-strength bolt.2. again with tower cylinder stage casing (or several joints stage casing) lifting, all bolts hole on the lower flange of tower cylinder stage casing and all bolts hole on the tower cylinder hypomere upper flange are located one by one, be connected and fixed after high-strength bolt.3. again with tower cylinder epimere lifting, all bolts hole on the tower cylinder epimere lower flange and all bolts hole on the upper flange of tower cylinder stage casing are located one by one, be connected and fixed after high-strength bolt.Along with the increase of sling height, add the swing of wind and suspension arm of crane when lifting at the scene, cause the tower cylinder that lifts by crane to produce swing aloft, bring difficulty for all bolts hole location on orchid connects between two sections tower cylinders, greatly reduce installation efficiency.Even sometimes making, transport, load and unload and depositing a small amount of distortion that easily causes tower drum flange in the process because of the tower cylinder, and cause occurring when installing at the scene indivedual or in a small amount bolt hole dislocation, high-strength bolt can not be connected and fixed.Give user's economic loss.
Three, the content of invention
The present invention provides a kind of can the solution in the Large-scale Wind Turbines between every section in whole the tower cylinder when lifting connects, all bolts hole are realized fast location, and can solve because of the tower cylinder and making, transport, load and unload and depositing a small amount of distortion that easily causes tower drum flange in the process, cause to occur when installing at the scene indivedual or in a small amount bolt hole dislocation, make the tower cylinder hoisting flange screw fast-positioning device of the problem that high-strength bolt can not be connected and fixed.
The present invention adopts following technological scheme:
Large-scale Wind Turbines tower cylinder hoisting flange screw fast-positioning device, it is characterized in that: in the flange screw (6) of tower drum flange (5), opening swelling taper sheath (4) is housed, opening swelling taper sheath (4) flushes with tower drum flange (5) inner plane, taper positioning shaft (1) is packed into by the taper direction of opening swelling taper sheath (4), refill and join pad (3) and locking nut (2) and carry out fasteningly, namely consist of the present invention.
Working principle:
Opening swelling taper sheath (4) is to adopt cone to cooperate by axially opening a port with taper positioning shaft (1), fastening along with locking nut (2), make taper positioning shaft (1) distending opening swelling taper sheath (4), because the size of flange screw (6) is certain value, it is tighter that locking nut (2) is twisted, opening swelling taper sheath (4) expansive force is larger just tighter with cooperating of flange screw (6), and taper positioning shaft (1) is more firm.
Advantage of the present invention:
The simple volume of this positioning device structure is little, can realize quick swelling guiding and location, and can solve because of the tower cylinder and making, transport, load and unload and depositing a small amount of resiliently deformable that easily causes tower drum flange in the process, cause to occur when installing at the scene indivedual or in a small amount bolt hole dislocation, high-strength bolt can not be connected and fixed, give the problem of user's economic loss, convenient disassembly.
Four, description of drawings
Fig. 1 is structural representation of the present invention,
Among the figure: 1-taper positioning shaft, 2-locking nut, 3-pad, 4-opening swelling taper sheath, 5-tower drum flange, 6-flange screw.
Five, embodiment
The specific embodiment of the invention is as follows, Large-scale Wind Turbines tower cylinder hoisting flange screw fast-positioning device, it is characterized in that: in the flange screw (6) of tower drum flange (5), opening swelling taper sheath (4) is housed, opening swelling taper sheath (4) flushes with tower drum flange (5) inner plane, taper positioning shaft (1) is packed into by the taper direction of opening swelling taper sheath (4), refill and join pad (3) and locking nut (2) and carry out fasteningly, namely consist of the present invention.
Taper positioning shaft (1), locking nut (2), pad (3), opening swelling taper sheath (4) are carbon steel material processing, and carry out surface heat and process.
Using method:
1, first positioning device is fixed on before the tower cylinder lifts on the bolt hole on foundation ring (base) upper flange, the quantity of positioning device can be selected 3～4 flange screws according to the size of flange diameter, positioning device to be spaced apart all screw center circle girths 3～4 (or circumference 120 degree～90 degree) uniform.
2, after the lifting of hypomere tower cylinder, hypomere tower cylinder lower flange and foundation ring (base) are when upper flange docks, require to drop to gradually locating cones bearing pin upper end in the positioning device according to tower cylinder docking orientation, because bullet shape is adopted in locating cones bearing pin upper end, therefore the bolt hole on the hypomere tower cylinder lower flange is under the guiding of locating cones bearing pin, just all bolts hole smoothly and on foundation ring (base) upper flange can positioned in alignment, then after all high-strength bolts being connected and fixed, again locking nut (2) is unclamped, make taper positioning shaft (1) opening swelling taper sheath (4) loosening, take off positioning device.With same operating method, again positioning device is fixed on the mounted tower cylinder hypomere upper flange, recurrence tower crane cylinder stage casing, make the bolt hole of the lower flange on the tower cylinder stage casing under the guiding of locating cones bearing pin, just smoothly with the hypomere upper flange on all bolts hole can positioned in alignment, after then all high-strength bolts being connected and fixed, again locking nut (2) is unclamped, make taper positioning shaft (1) perforate swelling taper sheath (4) loosening, take off positioning device.The like finish the assembly connection of whole tower cylinder.
