Description
Technical field
The utility model relates to electric armour clamp, is specifically related to a kind of power transmission line strain clamp.
Background technology
Strain clamp uses extensively in large-scale transmission line, respectively circuit to be dredged and circuit fixedly plays vital effect, in prior art, compression type strain clamp comprises the wire clip body of hollow, steel anchor and drainage plate, steel anchor generally uses grinding tool to be compressed in wire clip body, once not or the phenomenon such as wire clip body hollow tube generative center skew, there is the risk that steel anchor is drawn out wire clip body in compacting dynamics; Particularly present transmission of electricity demand is increasing, and the diameter of the transmission pressure of use is also large in change, and under the landform or atrocious weather of complexity, the risk that steel anchor is drawn out is larger.
Chinese Patent Application No. 201220430833.8(Authorization Notice No. CN202712790U) a kind of strain clamp is disclosed, comprise strain clamp body, steel anchor, drainage plate assembly and conduction wire clamp, the head end external cylindrical surface of strain clamp body is provided with conical section, this structure avoids head end in crimping process because stress is concentrated, and the nozzle distortion caused, but the improvement of this structure can only improve the stress of wire clip body end, the problem that steel anchor is drawn out from wire clip body fundamentally cannot be solved.
Utility model content
In view of this, the purpose of this utility model is for the deficiencies in the prior art, provides a kind of power transmission line strain clamp, the risk that the frustum cone structure cooperatively interacted by setting effectively prevents steel anchor to be drawn out from wire clip body.
For achieving the above object, the utility model by the following technical solutions:
A kind of power transmission line strain clamp, comprise wire clip body, steel anchor and drainage component, described wire clip body is hollow tube, described steel anchor one end arranges hanging hole, transmission pressure is serially connected in described wire clip body, the part that described steel anchor stretches out described wire clip body is column structure, and the part that described steel anchor stretches into described wire clip body is frustum cone structure, and described wire clip body arranges the container cavity matched with described frustum cone structure.
Preferably, the diameter that the diameter of described column structure is little with described frustum cone structure is identical, and described hanging hole and described steel anchor are welded to connect.
Preferably, the diameter that the diameter of described column structure is large with described frustum cone structure is identical, and one end that described frustum cone structure diameter is little arranges the fixture of fastening described transmission pressure.
Preferably, described wire clip body and described steel anchor all arrange tapped through hole, and described wire clip body is fixedly connected with by bolt arrangement with described steel anchor.
Preferably, described steel anchor and described hanging hole pass through Flange joint.
The beneficial effects of the utility model are:
Power transmission line strain clamp disclosed in the utility model, it is frustum cone structure that steel anchor stretches in wire clip body, wire clip body arranges container cavity with matching, by arranging the link position relation of frustum cone structure, effectively can increase the contact area of wire clip body and steel anchor, thus the Dispersion on surface that the pulling force that transmission pressure is produced contacts with each other to both, the pulling force that hinge structure the utility model steel anchor bears is born relatively by frustum cone structure, effective minimizing steel anchor is directly pulled out the risk of wire clip body, particularly in the area that weather conditions are severe, the utility model tension effect is more outstanding.
In addition, the diameter that steel anchor stretches out the diameter of wire clip body column structure little with the frustum cone structure stretching into wire clip body is identical, the utility model can be installed in wire clip body one end of overall for the steel anchor rear from wire clip body-namely penetrate transmission pressure, further hanging hole and steel anchor column structure are welded to connect, the simple and structure after installing of this installation process is also stablized.
In addition, the diameter that the diameter of steel anchor column structure is large with frustum cone structure is identical, one end that frustum cone structure diameter is large arranges the fixture of fastening transmission pressure, and this annexation is by power transmission line is fixed on fixture, makes power transmission line play tension steel anchor and wire clip body effect; In addition, wire clip body and steel anchor all arrange tapped through hole, and wire clip body is fixedly connected with by bolt arrangement with steel anchor, further increase the structural stability of steel anchor and wire clip body.
In addition, the flange that one end is arranged and hanging hole cooperatively interacts of steel anchor column structure, is bolted to connection between flange, the utility model can be made more convenient when dismounting.
To sum up, the utility model has the advantages such as Stability Analysis of Structures, strain insulator dynamics be strong.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment one;
Fig. 2 is the structural representation of the utility model embodiment two.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
Embodiment one
As shown in Figure 1, a kind of power transmission line strain clamp, comprise wire clip body 1, steel anchor and drainage component 3, wire clip body 1 and steel anchor 2 all arrange tapped through hole, wire clip body 1 is fixedly connected with by bolt arrangement 7 with steel anchor, wire clip body 1 is hollow tube, steel anchor left end welding hanging hole, transmission pressure runs through and stretches in wire clip body 1, the part that steel anchor stretches out wire clip body 1 is column structure 21, the part that steel anchor stretches into wire clip body 1 is frustum cone structure 22, and wire clip body 1 arranges the container cavity 5 matched with frustum cone structure; The diameter that the diameter of column structure 21 is less with frustum cone structure 22 is identical, and hanging hole 6 and steel anchor are welded to connect.
The utility model at steel anchor design frustum cone structure 22, and is connected with wire clip body 1, under making the utility model be subject to External Force Acting, keeps good stiffening effect, effectively avoids the risk that steel anchor gets loose.
Embodiment two
As shown in Figure 2, this enforcement is identical with the major part of embodiment one, unlike: the diameter that the diameter of column structure is larger with frustum cone structure is identical, one end that frustum cone structure diameter is little is hollow tube, hanging hole 6 is connected by steady pin with steel anchor, wire clip body 1 and steel anchor all arrange tapped through hole, and wire clip body is fixedly connected with by bolt arrangement with steel anchor.
In the present embodiment, the diameter that the diameter of column structure is larger with frustum cone structure is identical, and one end that frustum cone structure diameter is little arranges the fixture of fastening described transmission pressure 4, and fixture can use buckle and in addition bolt is fixed; Hanging hole 6 is connected by steady pin with steel anchor, and in the process of slight vibrations under the effect of electric wire wind-force, the mode that pin joint connects can alleviate the amplitude of vibrations, reduces the pulling force between steel anchor and wire clip body 1, improves the useful life of strain clamp; In addition, between steel anchor and wire clip body 1, in addition bolt 8 is fixed, and further strengthens structural stability of the present utility model, makes the utility model under rugged environment, play more lasting strain insulator effect.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, other amendments that those of ordinary skill in the art make the technical solution of the utility model or equivalently to replace, only otherwise depart from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of right of the present utility model.
