Abstract
The utility model relates to ultra-high-tension power transmission line technical field, is specifically related to a kind of Novel strain wire clamp.Drainage plate of the present utility model and conduction wire clamp adopt double contact, and tension force that drainage plate like this bears reduces, and avoid occurring overheatedly even burning red phenomenon; Argon arc welding interface is arranged on the middle part of aluminum pipe, can reduce the length of aluminum pipe main body, also can reduce the length of steel anchor, thus strain clamp overall structure is optimized; Aluminum pipe head end external cylindrical surface is provided with conical section, avoids head end because stress is concentrated in crimping process, and causes nozzle distortion; Steel anchor tab nose is set to tiltedly take on axle, plays positioning aluminium tube end, and ensures tight with aluminum pipe end contact after compaction, prevents rainwater from entering aluminum pipe; Be groove in the middle of conduction wire clamp, the root of groove is small sircle hole, to reduce the rigidity of touch panel, makes the contact of conduction wire clamp and drainage plate better when set bolt is fastening.
Description
Technical field
The utility model relates to ultra-high-tension power transmission line technical field, is specifically related to a kind of Novel strain wire clamp.
Background technology
Strain clamp can realize the drainage to overhead transmission line at work, and realize again fixing between overhead transmission line and strain insulator, strain clamp comprises a wire clip body, steel anchor, drainage plate and conduction wire clamp.The drainage one of strain clamp to overhead transmission line is that two is connect wire by conduction wire clamp by being inserted in by overhead transmission line in strain clamp body; Wherein drainage plate is fixedly connected on strain clamp body, and conduction wire clamp is connected on drainage plate.
There is following shortcoming in strain clamp of the prior art: 1. conduction wire clamp often occurs to carry out parallel contact with drainage plate or bottom contacts, and all belongs to single-contact mostly, easy loose contact or contact-making surface too small and cause overheated, even there is burning red phenomenon; 2. the argon arc welding interface of drainage plate is arranged on the root of aluminum pipe, occurs the situation producing fracture due to insufficient strength; 3. aluminum pipe whole installation is orthogonal, because stress is concentrated in crimping process, easily causes nozzle distortion.
Utility model content
For the deficiency that prior art exists, the utility model provides the Novel strain wire clamp that a kind of serviceability is good, can be suitable for the operation of ultra-high-tension power transmission line long-term stability.
The utility model is achieved through the following technical solutions:
A kind of Novel strain wire clamp, comprise aluminum pipe, the tail end of described aluminum pipe is connected with steel anchor, the head end external cylindrical surface of described aluminum pipe is provided with conical section, the upper surface middle part of described aluminum pipe is provided with argon arc welding interface, drainage plate is welded with in the middle part of the lower surface of described aluminum pipe, the both sides of described drainage plate are coated with conduction wire clamp, the centre of described conduction wire clamp is groove, the root of groove is small sircle hole, described drainage plate and conduction wire clamp are fixed by set bolt, and described set bolt carries out fastening or dismounting by nut.
Further, described steel anchor comprises draw ring and anchor pole, and described tab nose is set to inclined shaft shoulder.
Further, described drainage plate both sides are provided with gusset.
Compared with prior art, the beneficial effects of the utility model are:
1, drainage plate of the present utility model and conduction wire clamp adopt double contact, and tension force that drainage plate like this bears reduces, and avoid occurring overheatedly even burning red phenomenon;
2, argon arc welding interface of the present utility model is arranged on the middle part of aluminum pipe, can reduce the length of aluminum pipe main body, also can reduce the length of steel anchor, thus strain clamp overall structure is optimized;
3, aluminum pipe head end external cylindrical surface of the present utility model is provided with conical section, avoids head end because stress is concentrated in crimping process, and causes nozzle distortion;
4, steel anchor tab nose of the present utility model is set to tiltedly take on axle, plays positioning aluminium tube end, and ensures tight with aluminum pipe end contact after compaction, prevents rainwater from entering aluminum pipe;
5, drainage plate one side both sides of the present utility model arrange gusset, can strengthen the intensity of drainage plate and the connection of guiding drainage plate and conduction wire clamp;
6, be groove in the middle of conduction wire clamp of the present utility model, the root of groove is small sircle hole, to reduce the rigidity of touch panel, makes the contact of conduction wire clamp and drainage plate better when set bolt is fastening.

Accompanying drawing is structural representation of the present utility model.
In accompanying drawing: 1. aluminum pipe; 2. steel anchor; 3. drainage plate; 4. conduction wire clamp; 5. argon arc welding interface; 6. set bolt; 7. nut; 10. conical section; 21. inclined shaft shoulders.
Embodiment
A kind of Novel strain wire clamp, comprise aluminum pipe 1, the tail end of aluminum pipe 1 is connected with steel anchor 2, and the head end external cylindrical surface of aluminum pipe 1 is provided with conical section 10, and the upper surface middle part of aluminum pipe 1 is provided with argon arc welding interface 5, drainage plate 3 is welded with in the middle part of the lower surface of aluminum pipe 1, the both sides of drainage plate 3 are coated with conduction wire clamp 4, and the centre of conduction wire clamp 4 is groove, and the root of groove is small sircle hole, drainage plate 3 and conduction wire clamp 4 are fixed by set bolt 6, and set bolt 6 carries out fastening or dismounting by nut 7.
Further, steel anchor 2 comprises draw ring and anchor pole, and tab nose is set to inclined shaft shoulder 21.
Further, drainage plate 3 both sides are provided with gusset.
In sum, be only preferred embodiment of the present utility model, not be used for limit the utility model implement scope, all equalizations of doing according to shape, structure, feature and the spirit described in the utility model right change and modify, and all should be included in right of the present utility model.
