Abstract
The utility model discloses a kind of reinforced flange holes to combine, it is set on ring flange, include the flange hole being set on ring flange and the bolt matched with flange hole, it is characterized by: the flange hole both ends are each provided with a circular apparatus slot, corresponding device plug is set in device slot, be provided with the wide connecting hole in intermediate narrow both ends among described two device slots, the connecting hole periphery be provided with it is intermediate to connecting hole direction it is convex into arcwall.During pullling, device plug can effectively guarantee the safety of bolt, and the structure of device plug and connecting hole designs, and can effectively guarantee that flange hole is indeformable, be suitable for frequently transhipment operation.
Description
Technical field
The utility model relates to a kind of reinforced flange holes to combine, and belong to wind-power tower manufacturing field.
Background technique
In existing tower section manufacture craft, flange hole bolt in rotary course in tower section both ends, which is easy to squeeze in hole, to be become
Shape, and the screw thread of bolt is destroyed, so that bolt is also scrapped therewith after bore deformation.And the existing bolt sleeve of our company can be with
Solving the problems, such as bore deformation, but problem is that this bolt sleeve not can guarantee the service life of bolt, the usage amount of bolt increased dramatically,
And it is not suitable for frequently lifting by crane and loads.
Utility model content
In order to solve the above problem, the purpose of this utility model is to provide a kind of reinforced flange holes to combine, can be preferable
Solve the above problems.
The technical scheme that the utility model is provided is as follows:
A kind of reinforced flange hole combination, is set on ring flange, includes the flange hole being set on ring flange and and method
The bolt that flange aperture matches, it is characterised in that: the flange hole both ends are each provided with a circular apparatus slot, set in device slot with
Corresponding device plug, the wide connecting hole in intermediate narrow both ends, the connecting hole periphery are provided among described two device slots
Be provided with it is intermediate to connecting hole direction it is convex into arcwall.
Through-hole is provided among described device plug.
The diameter of the through-hole is equal to the most narrow aperture of connecting hole.
Internal screw thread is set in the through-hole, the internal screw thread is correspondingly arranged with the external screw thread being set on bolt.
The direction that described device plug is in contact with connecting hole is provided with loop buffer connector.
As can be seen from the above description, utility model has the advantages that bolt pass through a device plug through-hole after, pass through connect
It connects after hole passes through the through-hole of another device plug again and uses nut check.Device plug can offset inclination in the transport process of tower
The effect for the power pullled, and the shape design of connecting hole, can effectively prevent that bolt walks or device plug is illusive asks
Topic, therefore, during pullling, device plug can effectively guarantee the safety of bolt, and the knot of device plug and connecting hole
Structure design, can effectively guarantee that flange hole is indeformable, be suitable for frequently transhipment operation.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the cross-sectional view of the utility model flange hole；
Fig. 3 is the utility model flange hole and bolt combination schematic diagram.
Specific embodiment
The most basic embodiment of one kind of the utility model, as shown in Figure 1, 2, 3, a kind of reinforced flange hole combination, if
It is placed on ring flange 1, comprising the flange hole 2 being set on ring flange 1 and the bolt matched with flange hole 2, the flange hole 2
Both ends are each provided with a circular apparatus slot 5, set corresponding device plug 6 in device slot 5, in described two device slots 5
Between be provided with the wide connecting hole 4 in intermediate narrow both ends, 4 periphery of connecting hole be provided with it is intermediate to 4 direction of connecting hole it is convex into arc
Shape wall 3.
Through-hole 62 is provided among described device plug 6.
The diameter of the through-hole 62 is equal to the most narrow aperture of connecting hole 4.
Internal screw thread is set in the through-hole 62, the internal screw thread is correspondingly arranged with the external screw thread being set on bolt 7.
The direction that described device plug 6 is in contact with connecting hole 4 is provided with loop buffer connector 61.
As can be seen from the above description, utility model has the advantages that bolt 7 is worn after the through-hole 62 of a device plug 6
Connecting hole 4 is crossed again by being locked after the through-hole 62 of another device plug 6 with nut 71.The device plug 6 in the transport process of tower
The effect for the power that inclination is pullled, and the shape design of connecting hole 4 can be offset, bolt 7 is can effectively prevent and walks or fill
6 illusive problems of plug are set, therefore, during pullling, device plug 6 can effectively guarantee the safety of bolt 7, and fill
It sets plug 6 and the structure of connecting hole 4 designs, can effectively guarantee that flange hole 2 is indeformable, be suitable for frequently transhipment operation.
It above are only a specific embodiment of the utility model, but the utility model is not limited thereto, Fan Yiben is real
The equivalent changes and modifications made of novel claim should all belong to the covering scope of the utility model.
