Description

Strain clamp
Technical field
It the utility model is related to a kind of power equipment, and in particular to a kind of strain clamp.
Background technology
Overhead transmission line is fixed on anchor support cross-arm when passing through anchor support by the string of resistance to bracing cable, and uses wire jumper pair Overhead transmission line is drained the connection for having completed overhead transmission line, at this moment need using strain clamp complete overhead transmission line with it is resistance to The fixation between string is opened, plays and grips wire and the drainage to overhead transmission line.At present, each domestic manufacturer mainly provides Following three major types strain clamp:Bolt strain clamp, hydraulic pressure strain clamp and detonation pressure type strain clamp.It is resistance at this three In bracing cable folder, bolt strain clamp is commonly used in 10~110kv circuit using relatively broad.The resistance to bracing cable of hydraulic pressure Folder is commonly used in 110kv and the circuit of the above, and detonation pressure type strain clamp is because frequently result in wire dropping, therefore Stop using.
Bolt-type strain clamp includes strain clamp body, steel anchor, drainage plate and drainage folder, passes through at least two U-shaped spiral shells Bolt is fixed, and the strain clamp of this spline structure has following defect:In work progress, first tune is unclamped in fixation to multiple U-bolts again Solidating is determined, and work progress is complicated, and efficiency of construction is relatively low;Further, since strain clamp is not provided with wrapping post, can not wind long Wire, accurate measurement is needed before construction and is calculated, obtains required conductor length, correct amount line taking length, poor practicability.
Utility model content
In view of the deficienciess of the prior art, the utility model provides a kind of strain clamp, this strain clamp is simple in construction, It is easy to construct, efficiency of construction is high, calculates without accurate measurement before constructing, can wind longer wire, and is additionally provided with to offset to draw and answers The spring of power, ensure that wire is not easy to break, improve the service life of wire.
In order to achieve the above object, the technical scheme that the utility model is taken:
Strain clamp, including the wrapping post in tubular, the both ends of the wrapping post are equipped with lead plate in disk form, Two lead plates it is vertically arranged and symmetrically offer thereon it is some to threading hole, and the diameter of two lead plates be more than it is described around The diameter of terminal, wherein being provided with a draw ring for being in semicircle shape at the center of a lead plate, one is connected with the center of the draw ring The fix bar laterally set, the fix bar runs through two lead plates and wrapping post, and continues after the fix bar leadthrough plate Extend outward, the end of the fix bar connects a spring, and it is in the form of annular discs and vertically arranged that the end of the spring is connected to one Supporting plate on, one end of the supporting plate is connected with a cylindrical mounting post, and the mounting post is transversely mounted and thereon Offer mounting hole.
As optimal technical scheme, in order to ensure that strain clamp stabilized structure, intensity are big, corrosion-resistant, while insulating properties Good, the wrapping post and two lead plates are integrally formed and are made of ceramic materials.
As optimal technical scheme, in order to ensure the intensity of strain clamp, while corrosion resistance is improved, effectively extend strain insulator The service life of wire clamp, the fix bar, spring, supporting plate, mounting post are made of stainless steel material.
Compared with prior art, the utility model has the advantage that:
1st, this strain clamp sets the lead plate for offering threading hole, can quickly and easily fix wire, changes existing The defects of complex operation, a coiling is set, long wire can be wrapped on wrapping post, without accurate measurement before construction Calculate, longer wire can be wound, and be additionally provided with the spring for offsetting tension, ensure that wire is not easy to break, improve making for wire It is good with life-span, usability.
2nd, the structure of wrapping post and two lead plates, material are set scientific and reasonable, ensure strain clamp stabilized structure, intensity Greatly, it is corrosion-resistant, while good insulation preformance.
3rd, fix bar, spring, supporting plate, the material of mounting post are set scientific and reasonable, ensure the intensity of strain clamp, simultaneously Corrosion resistance is improved, effectively extends the service life of strain clamp.
Brief description of the drawings
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model;
Drawing reference numeral:1st, wrapping post, 2, lead plate, 3, threading hole, 4, draw ring, 5, fix bar, 6, spring, 7, supporting plate, 8th, mounting post, 9, mounting hole.
Embodiment
A kind of specific embodiment of the utility model, strain clamp, including the wrapping post 1 in tubular are proposed as shown in Figure 1, The both ends of the wrapping post 1 are equipped with lead plate 2 in disk form, and two lead plates 2 are vertically arranged and symmetrically open up thereon Have some to threading hole 3, the present embodiment only opens up 1 pair of threading hole 3, i.e. 2 threading holes 3, and the diameter of two lead plates 2 is more than institute The diameter of wrapping post 1 is stated, wherein a draw ring 4 for being in semicircle shape is provided with the center of a lead plate 2, at the center of the draw ring 4 A fix bar 5 laterally set is connected with, the fix bar 5 runs through two lead plates 2 and wrapping post 1, and the fix bar 5 runs through Continue to extend outward after the lead plate 2 of end, the end of the fix bar 5 connects a spring 6, the end connection of the spring 6 In a supporting plate 7 in the form of annular discs and vertically arranged, one end of the supporting plate 7 is connected with a cylindrical mounting post 8, the mounting post 8 is transversely mounted and offers mounting hole 9 thereon.
