Description
Technical field
The utility model is related to a kind of bolt sleeve groups, belong to wind-power tower manufacturing field.
Background technology
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 existing bolt sleeve of our company can solve the above problems, but problem is the tower that this bolt sleeve is suitble to ring flange thicker,
Namely more large-scale tower, therefore, the bolt sleeve for studying a suitable small-sized tower is the purpose of the utility model research.
Utility model content
In order to solve the above problem, it the purpose of this utility model is to provide a kind of special bolt set group, can preferably solve
The certainly above problem.
The technical scheme that the utility model is provided is as follows：
A kind of special bolt set group, including the bolt sleeve that two structures in left and right are consistent, it is characterised in that：The bolt sleeve packet
The supplementary card cylinder being connected containing master collet, with master collet, the outer circular layer being connected with supplementary card cylinder, the master collet include master
Cylinder, the main cylinder are internally provided with inner via hole, and the main cylinder is equipped with internal thread close to inner via hole side, outside the main cylinder in order
It is socketed with Auxiliary support layer and buffer layer；The supplementary card cylinder is connected to the tabs on master collet comprising one end, per two panels tabs
Between be all provided with there are one triangular space, the outer circular layer includes several outer ring plates, is connected on tabs per a piece of outer ring plate, and with
Tabs is connected at an angle of 90.
The tabs and outer ring plate include Auxiliary support layer and buffer layer.
As can be seen from the above description, the utility model has the advantage of：It is socketed respectively and flange hole using one group of bolt sleeve
Both ends so that bolt is not in direct contact with flange hole, to avoid causing to scratch to flange hole surface in rotation process.It is suitable for
Small-sized tower, and collect conveniently.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the utility model structural side view.
Specific implementation mode
A kind of most basic embodiment of the utility model, as shown in Figure 1, 2, a kind of special bolt set group, including left and right
The consistent bolt sleeve of two structures, the bolt sleeve include master collet 1, the supplementary card cylinder 2 being connected with master collet 1 and auxiliary
The outer circular layer 3 that card cylinder 2 is connected, the master collet 1 include main cylinder 11, and the main cylinder 11 is internally provided with inner via hole 12, the master
Cylinder 11 is equipped with internal thread 13 close to 12 side of inner via hole, is socketed with Auxiliary support layer 4 and buffering outside the main cylinder 11 in order
Layer 5；The supplementary card cylinder 2 is connected to the tabs 21 on master collet 1 comprising one end, described to be equipped with one between folding 21 per two panels
A triangular space 22, the outer circular layer 3 include several outer ring plates 31,31 are connected on tabs 21 per a piece of outer ring plate, and with folding
Piece 21 is connected at an angle of 90.
The tabs 21 and outer ring plate 31 include Auxiliary support layer 4 and buffer layer 5.
During use, master collet 1 and the clamping of supplementary card cylinder 2 enter in flange hole, and outer circular layer 3 is then exposed at outside flange hole.
As can be seen from the above description, the utility model has the advantage of：It is socketed respectively and flange hole using one group of bolt sleeve
Both ends so that bolt is not in direct contact with flange hole, to avoid causing to scratch to flange hole surface in rotation process.It is suitable for
Small-sized tower, and collect conveniently.
A specific embodiment of the utility model is above are only, 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.
