Description
Technical field
The utility model belongs to wind-force field, more particularly to a kind of large-scale wind driven generator pylon connection lever apparatus.
Background technology
Wind-powered electricity generation is the green energy resource having a high potential, it is contemplated that will all keep becoming for high speed development in following a very long time
Gesture.Wind turbines of the power more than hundred multikilowatts are referred to as large-scale wind electricity unit (hereinafter referred to as blower fan)；The pylon of large fan
Typically made of the steel pipe with taper.The function of pylon is to support to electricity generation system (cabin and runner) in the air, pylon
Higher, the wind energy that blower fan obtains is more, and the pylon of large fan has tens meters of even up to a hundred meters of height.In order to manufacture, transport and pacify
Dress is convenient, and large tower is broken generally into several sections, by taking 1500 kilowatts of power, highly 80 meters of blower fan pylon as an example, is divided into upper, middle and lower
Three sections.Epimere is connected with cabin, hypomere is connected with basis.Between each several part, using bolt-connection.Pylon stress is complicated, bears
The lower tension and compression twist and warping combination dynamic loading of blower fan gravity dead load, wind effect, also subject to wind wheel rotate caused by vibrate, it is wind-induced
Along-wind vibration and beam wind are to vibration.The service life of blower fan is normal and continuous operation 20 years, requires very high to attachment bolt.
Bolt connection structure is under vibration, on the one hand, clamping force easily declines, and causes the loosening of connected compcnent；Under serious conditions,
Bolt fracture is caused, causes serious accident.
There is gap between prior art high-strength bolt and bolt hole, frictional force caused by very big pretightning force can only be relied on
Square is born in the tilting moment of wind and fan operation under various vibration collective effects to transverse load caused by blower fan pylon,
The bolt strength grade that uses is high, diameter is big, quantity is more, and the adpting flange used is especially thick, and flange hole is especially intensive, even if such as
This, the problem of still can not overcoming bolt connection loosening.The research that process is loosened to thread joined structure is domestic and international project neck
The focus that domain studies for a long period of time, prior art also have following significant drawback：The bolt strength grade that uses is high, diameter is big, quantity is more,
The adpting flange used is not thick, and the especially intensive manufacturing cost of flange hole is high, and bolt-connection easily loosens, and maintenance cost is high.
Utility model content
The utility model is intended to for deficiency present in background technology, and a kind of large-scale wind driven generator pylon provided
Connect lever apparatus.
A kind of large-scale wind driven generator pylon connection lever apparatus of the present utility model, is made up of screw rod and locking nut,
One end of screw rod described in it is screw head, the other end is screw thread, and locking nut is used cooperatively with screw thread screw socket, and screw rod is from the inner
It is filled with the pushing ring of more than three to overcoat, uniform the tightening piece of more than three, locking screw is provided between adjacent pushing ring
Female the inner is provided with depressed part, and depressed part inner screw is provided with tensioner pushnut.
As further improvement of the utility model, the outer end of described pushing ring is provided with outside rake I, tightening piece
Internal both sides are equipped with inside rake II.
As further improvement of the utility model, resilient attachment arms are equipped between tightening piece.
As further improvement of the utility model, the inclination angle of the rake I and rake II is complementary.
As further improvement of the utility model, the diameter of described tensioner pushnut is not more than the internal diameter of depressed part
As further improvement of the utility model, the diameter of screw rod is identical with the internal diameter of pushing ring.
A kind of large-scale wind driven generator pylon connection lever apparatus of the present utility model, it is simple in construction easy to operate, can be complete
It totally disappeared except the gap between attachment bolt and bolt hole wall, and form certain magnitude of interference.Can thoroughly solve bolt-connection
Problem is loosened, the grade of high intensity screw is reduced, reduces quantity and dimensions, reduce the thickness of flange, so as to reduce
Manufacturing expense, also save high maintenance cost.Meanwhile huge compression is generated between connector and bolt hole wall
Power, so as to realize positive connection, with this bear wind tilting moment and fan operation in it is various vibration collective effects under to wind
Transverse load caused by machine pylon.Meanwhile its processing and installation is convenient, dead load that pylon is received, dynamic loading, the power of toppling of wind
Square and various vibrations fundamentally solve the problems, such as bolt looseness all without causing connection to loosen, the blower fan pylon of installation qualification,
It is very easily disassembled and it is taper-face contact to be provided between pushing ring between uniform the tightening piece of more than three.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is transverse sectional view of the present utility model.
Embodiment
