Abstract

The invention discloses a method for preventing a wind power tower outer flange junction surface from cracking. The method comprises the following steps that firstly two tower outer flanges are locked by flange bolts, and then the outer edges of the two tower outer flanges are secondarily clamped by a plurality of locking devices, so that the outer edges of the two tower outer flanges are tightly attached together. The invention aims at providing the method for preventing the wind power tower outer flange junction surface from cracking.

Description

A kind of for the anti-cracking method of wind power tower outward flange junction plane
[technical field]
The present invention relates to a kind ofly for the anti-cracking method of wind power tower outward flange junction plane, belong to wind power generation field.
[background technique]
The wind power tower outward flange is simple in structure because of it, has obtained using widely in the wind-powered electricity generation industry.But in the using process of reality, because the as easy as rolling off a log flange outside junction plane that makes of the effect of external force ftractures because of loosening, influenced the shelf life of pylon outward flange to a great extent, and the Security of pylon is greatly reduced.
[summary of the invention]
The objective of the invention is to overcome the present flange mating face deficiency of cracking easily, provide a kind of for the anti-cracking method of wind power tower outward flange junction plane, this method can prevent pylon outward flange junction plane cracking effectively, plays the effect of safety protection.
The present invention has adopted following technical proposals:
A kind of for the anti-cracking method of wind power tower outward flange junction plane, comprise the steps: at first to adopt flange bolt to lock two pylon outward flanges; Adopt a plurality of locking devices that two pylon outward flange outer rim secondaries are clamped again.
A kind of for the anti-cracking method of wind power tower outward flange junction plane as mentioned above, it is characterized in that: two jam plates and lock bolt are formed a locking device, a plurality of locking device circle distribution are along with pylon outward flange external diameter increases or reduces and increase or reduce the locking device number.
A kind of for the anti-cracking method of wind power tower outward flange junction plane as mentioned above, it is characterized in that: in advance in two pylon outward flange outer rim machined grooves, and then wherein a jam plate one end embeds in the groove of a pylon outward flange, another jam plate one end embeds in the groove of another pylon outward flange, two jam plates is linked to each other lock with lock bolt after end is fitted then.
A kind of for the anti-cracking method of wind power tower outward flange junction plane as mentioned above, it is characterized in that: along with pylon outward flange external diameter increases and increase jam plate circumferential width.
The present invention with respect to the beneficial effect of prior art is:
1, at first adopt flange bolt to lock two pylon outward flanges among the present invention; Adopt a plurality of locking devices that two pylon outward flange outer rim secondaries are clamped again, thereby two pylon outward flange outer rims are tightly fit together, can prevent pylon outward flange junction plane cracking so effectively, play the effect of safety protection.
2, two jam plates are formed a locking device with the lock bolt that firmly is connected two jam plates, locking device can adopt a plurality of, each locking device is along pylon outward flange circumference uniform distribution, two pylon outward flanges adopt prior art to connect locking by flange bolt earlier, further targetedly two pylon outward flange outer rims are reinforced the connection by method among the present invention again.
3, increase along with pylon outward flange external diameter and increase the locking device number and/or along with pylon outward flange external diameter increases and increase the jam plate circumferential width, further firm two pylon outward flange outer rims connect, effectively prevent wind power tower outward flange outside junction plane cracking.

Fig. 5 be among the present invention the locking device perspective view two.
[embodiment]
As shown in Figure 1 to Figure 3, two pylon outward flanges 3 on tower tube barrel 1 and the tower tube barrel 5 are symmetrical arranged up and down.
A kind of for the anti-cracking method of wind power tower outward flange junction plane, comprise the steps: at first to adopt flange bolt 2 lockings two pylon outward flanges 3; Adopt a plurality of locking devices 4 that two pylon outward flange outer rim secondaries are clamped again.A plurality of locking device circle distribution are along with pylon outward flange external diameter increases or reduces and increase or reduce the locking device number; Along with pylon outward flange external diameter increases and increase jam plate circumferential width.
Locking device 4 as shown in Figure 4 and Figure 5, it is made up of jam plate 6, jam plate 8 and two lock bolts 7, jam plate 6 and jam plate 8 are symmetrical arranged up and down, jam plate 6 is provided with plane connecting end 61, jam plate 8 is provided with plane connecting end 81, plane connecting end 81, two lock bolts on the plane connecting end 61 applying jam plates 8 on the jam plate 6 tightly pass tight plane connecting end 61, the plane connecting end 81 of pinning behind the attachment hole on plane connecting end 61, the plane connecting end 81; Jam plate 6 is provided with the latch hook 62 that can embed in pylon outward flange 3 circumferential grooves, and jam plate 8 is provided with the latch hook 82 that can embed in another pylon outward flange 3 circumferential grooves.
Wherein, can to adopt lateral cross section be the arc section (not shown) of pylon outward flange arc edge of reclining for jam plate 6 and jam plate 8; It is that an end buckle the other end is the cross section structure on butt joint plane that jam plate 6 or jam plate 8 also can adopt the longitudinal cross-section.
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.
