Abstract
The invention discloses a locking structure for preventing outer flange joint faces of wind power towers from cracking. The locking structure comprises an upper tower outer flange and a lower tower outer flange which are used for connecting the barrel walls of two tower barrels, and the middle portions of the outer flanges of the two towers are locked through a plurality of flange bolts. The locking structure further comprises a plurality of locking devices, each locking device is composed of two locking plates and locking bolts, the two lock plates tightly fasten the outer edges of the outer flanges of the two towers from the upper side and the lower side respectively, and the two locking plates are firmly connected under the action of locking force of the locking bolts. The locking structure for preventing the outer flange joint faces of the wind power towers from cracking is provided, and the locking structure can effectively prevent the outer 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 a kind of locking structure, particularly a kind of for the anti-cracking of wind power tower outward flange junction plane locking structure, 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, the anti-cracking of a kind of wind power tower outward flange junction plane locking structure is provided, this locking structure can prevent pylon outward 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 outward flange junction plane locking structure, comprise the upper and lower two pylon outward flanges that connect for two tower tube barrels, two pylon outward flanges middle part is by a plurality of flange bolt lockings, it is characterized in that: also comprise a plurality of locking devices, locking device is made up of two jam plates and lock bolt, and link closely from upper and lower both sides respectively two pylon outward flange outer rims and two jam plates of two jam plates firmly connect under the effect of lock bolt coupling mechanism force.
Further improve: a plurality of locking devices are along pylon outward flange circumference uniform distribution.
Further improve: two jam plates are symmetrical arranged up and down, and two jam plates are respectively equipped with the plane connecting end that can fit mutually, and lock bolt tightly pins the plane connecting end on two jam plates; Wherein a jam plate is provided with the latch hook that can embed in the pylon outward flange circumferential groove, and another jam plate is provided with the latch hook that can embed in another pylon outward flange circumferential groove.
Further improve: the lateral cross section of jam plate is the arc section of the pylon outward flange arc edge that can recline; The longitudinal cross-section of jam plate is that an end is convenient to embed in the groove of pylon outward flange, and the other end is convenient to " 2 " tee section with another jam plate applying.
The present invention with respect to the beneficial effect of prior art is:
1, firmly connects under the effect of lock bolt coupling mechanism force with link closely from upper and lower both sides respectively two pylon outward flange outer rims and two jam plates of two jam plates among the present invention; 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 respectively equipped with the connecting end that can fit mutually, and lock bolt tightly pins the plane connecting end on two jam plates; Wherein a jam plate is provided with the latch hook that can embed in the pylon outward flange circumferential groove, another jam plate is provided with the latch hook that can embed in another pylon outward flange circumferential groove, make locking device self be connected firmly, the connection dynamics of two pylon outward flange outer rims thereby assurance is linked closely prevents pylon outward flange junction plane cracking.

[embodiment]
Extremely shown in Figure 5 as Fig. 1, the anti-cracking of a kind of wind power tower outward flange junction plane locking structure, comprise for the upper and lower two pylon outward flanges 3 and a plurality of locking device 4 that are connected on tower tube barrel 1 and the tower tube barrel 5, two pylon outward flanges, 3 middle parts are by a plurality of flange bolt 2 lockings, locking device 4 is made up of jam plate 6, jam plate 8 and lock bolt 7, and link closely from upper and lower both sides respectively two pylon outward flanges, 3 outer rims and jam plate 6, jam plate 8 of jam plate 6, jam plate 8 firmly connects under lock bolt 7 coupling mechanism force effects.
Specific embodiment is: a plurality of locking devices 4 are along pylon outward flange 3 circumference uniform distributions.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 7 on the plane connecting end 61 applying jam plates 8 on the jam plate 6 be arranged in parallel and pass tight plane connecting end 61, the plane connecting end 81 of pinning behind a pair of 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 a 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 all 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; The longitudinal cross-section of jam plate is that an end buckle and the other end are the cross section on butt joint plane.
Can also be along with pylon outward flange 3 external diameters increase and increase jam plate horizontal width.Locking device 4 can adopt a plurality of, and each locking device 4 can also increase and increase locking device 4 numbers along with pylon outward flange 3 external diameters along pylon outward flange 3 circumference uniform distributions.
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.
