The structure for preventing the inner flange joint faces of the wind power towers from cracking is provided, and the structure can effectively prevent the inner flange joint faces of the wind power towers from cracking, and has the effect of safety protection.
Description
[technical field]
The present invention relates to the anti-cracking of a kind of wind power tower inner flange junction plane structure, belong to wind power generation field.
[background technique]
Traditional wind power tower inner flange mostly is " L " shape structure, and flange is to connect by flange bolt singlely.In the using process of reality, because the as easy as rolling off a log inner flange junction plane cracking that causes of the effect of external load causes the linking intensity of flange bolt structure to reduce, has very high risk.
[summary of the invention]
The objective of the invention is to overcome the present flange mating face deficiency of cracking easily, the anti-cracking of a kind of wind power tower inner flange junction plane structure is provided, this structure can prevent pylon inner flange junction plane cracking effectively, plays the effect of safety protection.
The present invention has adopted following technical proposals:
The anti-cracking of a kind of wind power tower inner flange junction plane structure, comprise the two pylon inner flanges that connect two pylon barrels, lock by a plurality of flange bolts between the two pylon inner flanges, in the close mutual bonding surfaces of two pylon inner flanges, two pylon inner flange inboards have the slope mouth, and the slope mouth on the two pylon inner flanges is mutually near forming a wedge slot; One arc wedge inserts in this wedge slot, the upper and lower side applying of arc wedge wedge slot both sides; One locking long arc plate two ends link to each other with two pylon inner flanges by chek bolt respectively and locking long arc plate roof pressure in arc wedge outer end.
A kind of wind power tower inner flange junction plane is prevented the cracking structure as mentioned above, it is characterized in that: be reserved with boss near the mutual bonding surfaces of two pylon inner flanges inboard, form draw-in groove between boss and its place pylon inner flange inner edge flanging, two short arc plates are stuck in the draw-in groove on the upper and lower two pylon inner flanges, and locking long arc plate upper and lower end is respectively by chek bolt and the locking of two short arc plates.
A kind of wind power tower inner flange junction plane is prevented the cracking structure as mentioned above, it is characterized in that: two short arc plates, locking long arc plate, arc wedge and the chek bolt that is connected short arc plate, locking long arc plate are formed an anti-cracking device, anti-cracking device can adopt a plurality of, and each anti-cracking device is uniform along pylon inner flange inner circumference.
The present invention with respect to the beneficial effect of prior art is:
1, the present invention can pass through the pretension chek bolt, and locking long arc plate imposes on the arc wedge to locking drag, by the arc wedge locking drag is passed to two pylon inner flanges then, thereby reaches the purpose of the anti-cracking of pylon inner flange junction plane, and is simple in structure, easy to use.
2, can increase or reduce the circumferential width of short arc plate, locking long arc plate according to pylon inner flange size, further two pylon inner flanges prevent the junction plane cracking, play the effect of safety protection.

[embodiment]
It is shown in Figure 5 as Fig. 1,
The anti-cracking of a kind of wind power tower inner flange junction plane structure, comprise the two pylon inner flanges 8 that connect pylon barrel 6 and pylon barrel 9, lock by a plurality of flange bolts 7 between the two pylon inner flanges 8, in close two pylon inner flanges, 8 mutual bonding surfaces, two pylon inner flanges, 8 inboards have the slope mouth, and the slope mouth on the two pylon inner flanges is mutually near forming a wedge slot 10; One arc wedge 5 inserts in this wedge slot 10 arc wedge 5 upper and lower side applying wedge slots 10 both sides; One locking long arc plate, 4 two ends respectively by chek bolt 3 link to each other with two pylon inner flanges 8 and locking long arc plate 4 roof pressures in arc wedge 5 outer ends.
Wherein, be reserved with boss 11 near two pylon inner flanges, 8 mutual bonding surfaces inboards, form draw-in groove between boss 11 and its place pylon inner flange 8 inner edge flangings, two short arc plates 2 are stuck in the draw-in groove on the upper and lower two pylon inner flanges 8, locking long arc plate 4 upper and lower ends are locked by chek bolt 3 and two short arc plates 2 respectively, thereby realize that locking long arc plate 4 is connected with 8 lockings of two pylon inner flanges.
Working principle of the present invention is: by pretension chek bolt 3, locking long arc plate 4 imposes on arc wedge 5 to locking drag, by arc wedge 5 locking drag is passed to two pylon inner flanges 8 then, thereby making firmly to connect between the two pylon inner flanges 8 does not become flexible the purpose that reaches the anti-cracking of pylon inner flange 8 junction planes.
Further improve: two short arc plates 2, locking long arc plate 4, arc wedge 5 and the chek bolt 3 that is connected short arc plate 2, locking long arc plate 4 are formed an anti-cracking device 1(and are seen Fig. 1 and Fig. 4, Fig. 5), anti-cracking device 1 has a plurality of, and each anti-cracking device 1 is uniform along pylon inner flange 8 inner circumferences.
During actual the use, can increase or reduce the circumferential width of preventing cracking device 1 number or increasing or reducing short arc plate 2, locking long arc plate 4 according to pylon inner flange 8 sizes according to pylon inner flange 8 sizes.
Above-described embodiment is preferred embodiment of the present invention; but embodiments of the present invention are not subjected to the restriction of above-described embodiment; change, the decoration of doing under other any the present invention of not deviating from spirit essence and the principle, substitute, combination or simplify the substitute mode that all should be equivalent, be included in protection scope of the present invention.
