Description
Technical field
This utility model relates to a kind of high intensity studs anticreep attachment structure.
Background technology
Wind power generating set is made up of blade, drive system, electromotor, energy storage device, pylon and electric system.Leaf
Sheet is used for receiving wind-force, and transfers electric energy to by drive system and electromotor.Blade is the most basic in wind-driven generator and closes most
The parts of key, the length of blade of Large-scale Wind Turbines is all more than 20 meters, and the currently used blade of marine wind electric field is about
Being 40 to 60 meters long, maximum blade diameter has been even up to 126 meters, existing wind power generating set Leaf and biography
The connection of dynamic system mainly uses studs auxiliary connection, and this studs auxiliary connection is mainly by studs, hexagonal spiral shell
Female, T-nut and packing ring composition, wind power generating set is in operation process, and blade bears answering of drawing, turn round, cut and shake
Close alternate load, and existing studs auxiliary connection can be loosened by this alternate load effect for a long time, thus affect
The normal table of wind power generating set runs.
Utility model content
The purpose of this utility model is: provide a kind of high intensity studs anticreep attachment structure, to solve prior art
The problem existed.
The technical solution of the utility model is: a kind of high intensity studs anticreep attachment structure, including studs, joins
The nut overlapped and the connecting hole being used for installing studs, described nut is integrally made up of hex nut and column type nut
T-nut, the periphery of column type nut is provided with at least one ratchet, described connecting hole is the step that outer imperial palace is little
Hole, the aperture of the macropore section of described stepped hole is more than the external diameter of described barrel nut, and the hole depth of this stepped hole macropore section is less than
The length of described barrel nut, offers spin-ended join unidirectional with described ratchet in the inner circumferential wall of described stepped hole macropore section
The ratchet closed.
Described ratchet is rotated by bearing pin and is assemblied on barrel nut outer peripheral face in the corresponding mounting groove offered, and is installing
Elastic spring it is top-loaded with between groove and ratchet.
The external diameter of described hex nut is more than the external diameter of described barrel nut.
High intensity studs anticreep attachment structure of the present utility model is by the ratchet installed on nut and connecting hole
The ratchet arranged coordinates, and makes nut cannot rotate backward after tightening, ensures that wind power generating set Leaf and transmission
Being reliably connected between mechanism, effectively prevent loosening of nut, it is ensured that the operating of wind power generating set safety and stability, its knot
Structure is simple, it is easy to connect to install, and efficiently solves the problem that prior art exists.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model high intensity studs anticreep attachment structure；
Fig. 2 is the upward view of nut in Fig. 1；
Fig. 3 is the top view of connecting hole in Fig. 1.
Detailed description of the invention
The specific embodiment of high intensity studs anticreep attachment structure of the present utility model as shown in Figure 1, Figure 2, Figure 3 shows,
It includes studs 1, supporting nut 2 and for installing the connecting hole 3 of studs, wherein, supporting with studs 1
Nut 2 be integrally made up of conventional hex nut 4 and column type nut 5 two parts, the external diameter of hex nut 4 is more than
The external diameter of barrel nut 5, so that it is monolithically fabricated T-nut structure, is provided with at least on the periphery of column type nut 5
One elastic pawl 7, in the present embodiment, it is to be evenly distributed in two mounting grooves on the outer peripheral face of barrel nut 5, two peaces
That passes through bearing pin 8 correspondence in tankage respectively is provided with two ratchets 7, is top-loaded with respectively between the ratchet 7 of mounting groove and correspondence
Elastic spring 6.Connecting hole 3 is the stepped hole that outer imperial palace is little, and wherein, the aperture section 9 of connecting hole 3 is used for coordinating with studs 1,
Pass for studs 1；The macropore section 10 of connecting hole 3 is for coordinating with barrel nut 5, and the aperture of this macropore section 10 is more than circle
The external diameter of cylindricality nut 5, the hole depth of this macropore section 10, less than the length of barrel nut 5, is mainly used in inserting for barrel nut 5
Enter, meanwhile, the inner circumferential wall of this macropore section 10 offers the spin-ended ratchet 11 that coordinate unidirectional with ratchet 7.
Claims (3)
