Abstract
The utility model discloses a kind of flange hole guiding mechanism, including first flange and pilot pin, first flange hole is provided with the first flange, the one side of the first flange has been fitted and connected second flange, and second flange hole is offered in the second flange, first flange hole and second flange hole are run through in one end of the pilot pin, the flange hole correcting is in the live tower mechanism of Wind Power Stations, during assembling, because Wind Power Stations are in the remote ground in field, construction environment is poor, big machinery is not easily accessible operation, cause the equipment such as large-scale forcing press cannot be introduced into and operation is carried out inside tower, therefore the flange for losing circle can will be quickly deformed by pilot pin to recover to original circularity, the device is easy to use, it is easy to carry, it is simple to operate, reduction uses space.
Description
Technical field
The utility model belongs to guiding mechanism technical field, and in particular to a kind of flange hole guiding mechanism.
Background technology
It, for the important connection member between wind-power tower, is also the weak link among tower production, still that flange, which is,
Because flange diameter is larger, and plasticity of flange material itself is very good, after tower is placed for a long time, is acted on by power, tower
Elastic deformation easily occurs for the flange at two ends, so that the circularity of flange is exceeded, the Wind Power Stations process that tower is assembled at the scene
In, two section towers are linked together by the high-strength bolt between flange and flange up and down, and the exceeded flange of circularity can cause height
Strength bolt be able to not can not link together normally through tower above and below in the bolt hole on flange, so resulting in, installation difficulty
Improve, be difficult correction, be this we have proposed a kind of flange hole guiding mechanism, the flange that circularity can be made exceeded passes through mechanism
Work recover circularity, meet the requirement of normal bolt connection.
Utility model content
The purpose of this utility model is to provide a kind of flange hole guiding mechanism, to solve what is proposed in above-mentioned background technology
Problem.
To achieve the above object, the utility model provides following technical scheme：A kind of flange hole guiding mechanism, including first
First flange hole is provided with flange and pilot pin, the first flange, the one side of the first flange has been fitted and connected
Second flange hole is offered on two flanges, and the second flange, first flange hole and second are run through in one end of the pilot pin
Flange hole.
It is preferred that, the pilot pin is made up of Hardmetal materials.
It is preferred that, the pilot pin includes guide way, and the guide way is the cylinder that a kind of Hardmetal materials are made
Metal straight rod.
It is preferred that, the two ends of the guide way are provided with guide head, and the guide head is a kind of tapered circular cone of band
Body metal cone forming head.
It is preferred that, the diameter and the diameter in first flange hole and the correcting hole of second flange hole formation of the guide way
Size is adapted, and mutually forms interference fits.
It is preferred that, the two ends of the pilot pin offer centre bore.
Technique effect of the present utility model and advantage：The flange hole correcting in the live tower mechanism of Wind Power Stations, assembling
During, because Wind Power Stations are in the remote ground in field, construction environment is poor, and big machinery is not easily accessible operation, causes large-scale
The equipment such as forcing press cannot be introduced into operation is carried out inside tower, therefore can will quickly be deformed by pilot pin and lose round method
Orchid recovers to original circularity, and the device is easy to use, is easy to carry, simple to operate, and reduction uses space.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
The utility model provides a kind of flange hole guiding mechanism as Figure 1-4, including first flange 1 and pilot pin
5, the pilot pin 5 is made up of Hardmetal materials, increases the service life of pilot pin 5, is easy to use hydraulic hammer pressure correcting,
First flange hole 3 is provided with the first flange 1, the one side of the first flange 1 has been fitted and connected second flange 2, and
Second flange hole 4 is offered in the second flange 2, first flange hole 3 and second flange hole are run through in one end of the pilot pin 5
4, the pilot pin 5 includes guide way 7, and the guide way 7 is the cylindrical metal straight-bar that a kind of Hardmetal materials are made, just
In correcting, while preventing stress is excessive from causing damaged fracture, the two ends of the guide way 7 are provided with guide head 6, described to be oriented to
First 6 be a kind of tapered cone metal cone forming head of band, with the tapered cone metal cone forming head in 2-8 degree, is easy to the
One flange hole 3 and the alignment correcting of second flange hole 4, diameter and first flange hole 3 and the shape of second flange hole 4 of guide way 7
Into the diameter in correcting hole be adapted, and mutually form interference fits, prevent pilot pin 5 excessively thick or meticulous cause after correcting
Deviation is produced, the two ends of the pilot pin 5 offer centre bore, auxiliary hydraulic pressure hammer connection.
Operation principle：Different guide ways 7 are made according to different flange bolt holes, by the method for first flange hole 3 and second
Can be on 4 pairs of upper first flange hole 3 and second flange hole, while simultaneously as far as possible by first flange hole 3 and in flange aperture 4
On two 4 pairs of flange holes；Then high-strength bolt is fastened on to leading that upper first flange hole 3 and second flange hole 4 are formed
In positive hole, the correcting since the less flange hole of deviation, successively after correcting, flange will recover original circularity, during correcting,
After pilot pin 5 is inserted, apply certain pressure by hydraulic hammer, paying special attention to application pressure need to slowly be carried out, and pilot pin 5 is complete
After insertion, the flange hole is to recover to original position.
In early stage first to upper flange hole on the basis of carry out correcting again to the flange hole on not, close to upper flange hole
Nearby that should be that deviation is minimum to the hole on not, and the correcting since the minimum hole of deviation after pilot pin 5 is inserted, is led to
Crossing the taper guide head 6 of the end of pilot pin 5 can enter in first flange hole 3 and second flange hole 4, by hydraulic hammer to correcting
After pin 5 pressurizes, the part of guide way 7 of pilot pin 5 fully enter above and below i.e. completion correcting process in two flange holes.
Finally it should be noted that：Preferred embodiment of the present utility model is the foregoing is only, this is not limited to
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it can still modify to the technical scheme described in foregoing embodiments, or to which part technical characteristic
Equivalent substitution is carried out, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvements made etc.,
It should be included within protection domain of the present utility model.
