Abstract
The utility model discloses a composite material cross arm fitting, which comprises a composite material cross arm body, wherein a sleeve is arranged in the composite material cross arm body in the transverse direction, and the length of the sleeve is matched with the transverse size of the composite material cross arm body. The composite material cross arm body is fixedly arranged on a rod tower by inserting bolts in the sleeve when mounting and by adding the sleeve in the composite material cross arm body, and tightening force of the bolts is directly applied on the sleeve, and is not applied on the composite material cross arm body, thereby enabling the composite material cross arm body not to deform, preventing stress concentration, and guaranteeing performance of a composite material cross arm. The composite material cross arm fitting is suitable for power transmission.
Description
Technical field
The utility model relates to electric power transport field, particularly a kind of composite material cross arm gold utensil.
Background technology
Before the utility model proposes, composite material cross arm, as the important link that connects transmission tower and wire, must have good mechanical property.Described composite material cross arm is generally fixed on shaft tower by bolt, but while constructing at the scene, owing to cannot accurately controlling the dynamics of tightening of described bolt, so often there is the phenomenon that bolt is excessively stubborn, described bolt will cause the surface of described composite material cross arm to produce distortion after crossing and twisting, thereby cause that composite material cross arm produces stress and concentrates, and then affect the performance on composite material cross arm surface.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiency of above-mentioned background technology, provides a kind of and can effectively avoid the concentrated composite material cross arm gold utensil of stress.
In order to realize above object, a kind of composite material cross arm gold utensil that the utility model provides, comprise composite material cross arm body, in described composite material cross arm body, be laterally provided with sleeve, the length of described sleeve matches with the lateral dimension of described composite material cross arm body.By add sleeve in described composite material cross arm body, during installation, bolt interts and in described sleeve, described composite material cross arm body is fixed on shaft tower, the screwing force of bolt is applied directly on described sleeve like this, rather than be applied on described composite material cross arm body, just can not make described composite material cross arm body produce distortion, thereby avoid stress to concentrate, guarantee the performance of composite material cross arm.
In such scheme, between described sleeve and composite material cross arm body, by Foamex packing material, fix, between described sleeve and composite material cross arm body, relatively move avoiding.
In such scheme, described sleeve surface is provided with fixed groove, to improve the fastness connecting between described sleeve and composite material cross arm body.
In such scheme, the shape of cross section of described sleeve is square, circle or oblong.
In such scheme, described sleeve is metal material materials and parts.
The beneficial effects of the utility model are: on the one hand, by add sleeve in described composite material cross arm body, during installation, bolt interts and in described sleeve, described composite material cross arm body is fixed on shaft tower, the screwing force of bolt is applied directly on described sleeve like this, rather than is applied on described composite material cross arm body, just can not make described composite material cross arm body produce distortion, thereby avoided stress to concentrate, guaranteed the performance of composite material cross arm; On the other hand, by Foamex packing material, described sleeve is fixed in described composite material cross arm body, has avoided relatively moving between described sleeve and composite material cross arm body; Finally, by adding fixed groove in described sleeve surface, improved the fastness connecting between described sleeve and composite material cross arm body.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the cross-sectional view along A-A line in Fig. 1;
Fig. 3 is that Fig. 2 removes the structural representation after Foamex packing material.
In figure, composite material cross arm body 1, sleeve 2, fixed groove 2a, Foamex packing material 3.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
As shown in Figure 1, a kind of composite material cross arm gold utensil that the present embodiment provides, comprise composite material cross arm body 1, the interior sleeve 2 that is laterally provided with of described composite material cross arm body 1, the length of described sleeve 2 matches with the lateral dimension of described composite material cross arm body 1.By add sleeve 2 in described composite material cross arm body 1, during installation, bolt interts and described composite material cross arm body 1 is fixed on shaft tower described sleeve 2 is interior, the screwing force of bolt is applied directly on described sleeve 2 like this, rather than be applied on described composite material cross arm body 1, just can not make described composite material cross arm body 1 produce distortion, thereby avoid stress to concentrate, guarantee the performance of composite material cross arm.
Between above-mentioned sleeve 2 and composite material cross arm body 1, by Foamex packing material 3 is fixing, form wholely, between described sleeve 2 and composite material cross arm body 1, relatively move avoiding.During concrete enforcement, first described sleeve 2 is inserted in described composite material cross arm body 1, the position of the described sleeve 2 of then having good positioning, and described Foamex packing material 3 is filled in described composite material cross arm body 1.Described sleeve 2 surfaces are provided with fixed groove 2a, to improve the fastness connecting between described sleeve 2 and composite material cross arm body 1.The shape of cross section of described sleeve 2 is square, circle or oblong.Described sleeve 2 is metal material materials and parts.
The utility model by adding sleeve 2 in described composite material cross arm body 1, during installation, bolt interts and described composite material cross arm body 1 is fixed on shaft tower described sleeve 2 is interior, the screwing force of bolt is applied directly on described sleeve 2 like this, rather than be applied on described composite material cross arm body 1, just can not make described composite material cross arm body 1 produce distortion, thereby avoid stress to concentrate, guarantee the performance of composite material cross arm; By Foamex packing material 3, described sleeve 2 is fixed in described composite material cross arm body 1, has avoided relatively moving between described sleeve 2 and composite material cross arm body 1; Finally, by adding fixed groove 2a on described sleeve 2 surfaces, improved the fastness connecting between described sleeve 2 and composite material cross arm body 1.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
