Description
Technical field
The utility model belongs to the electric wire suspension arrangement technical field of power transmission line, relates to a kind of wire clamp, particularly relates to a kind of bolt-type strain clamp.
Background technology
Strain clamp is for being fixed on the insulator string of tension-resistant rod or terminal shaft tower, fixation of weighing anchor by wire or lightning conducter.Existing strain clamp comprises screw bolt-type and crimp type two kinds, and screw bolt-type cable clamp structure generally comprises wire clip body, U-bolt, briquetting or pressing plate; More complicated is installed, is not easy location, and when wire is fastening bottom contact be point cantact, rubbing surface is smaller and easily damage wire and wire easily gets loose; The material that screw bolt-type wire clamp uses mostly is magnetic material, easily forms closed magnet ring during use, and magnetic hysteresis loss is serious and energy consumption is higher.Crimp type strain clamp to hold power smaller, wire easily gets loose; Construction needs special special construction machine, and technological requirement is all higher with investment, and wire clamp can not reuse after use, serious waste of resources.Traditional wire clamping structure is unreasonable, runs into atrocious weather in use procedure, and particularly during strong wind weather, the large not wire of wire clamp fastening force easily gets loose; And blow lower wire at high wind to rock to contact with wire clamp tail end and easily cause it to wear and tear, affect the useful life of wire, serious also can bring certain danger.
Summary of the invention
It is large not that the utility model holds power for traditional wire clamp, and structure is reasonable not, affects the problems such as wire useful life and propose a kind of bolt-type strain clamp be very practical.
In order to achieve the above object, the utility model adopts following technical scheme to realize:
A kind of bolt-type strain clamp; comprise wire clip body; described wire clip body comprises wire clamp briquetting, U-bolt, non magnetic protection tube; described wire clip body is aluminium alloy nonmagnetic substance; described wire clamp briquetting to be located at bottom U-bolt and to be coordinated with U-bolt fastening, and the opening part at described wire clip body top is provided with the hex bolts run through up and down, described hex bolts and nut screw connection tightening; described wire clip body inside is provided with waveform wire casing, and described non magnetic protection tube is close to wire casing inwall.
As preferably, the afterbody of described hex bolts is provided with the bolt pin running through hex bolts afterbody.
As preferably, described wire clip body bottom opened extremity and top opened extremity are outward extending turnup structure.
As preferably, inside described non magnetic protection tube, be evenly provided with strip projected parts structure.
Compared with prior art, advantage of the present utility model and good effect are:
1. the utility model strain clamp adopts high strength and the aluminium alloy entirety with reliability and stability is stamped to form, replace traditional cast iron, whole wire clamp not only quality is light, long service life, and effectively can solve the problem of wire clamp in use magnetic loss power consumption.
2. the utility model cable clamp structure is reasonable, and it is large that wire holds power, effectively to alleviate in use procedure wire clip body to the degree of wear of wire epidermis, energy-saving safe, easy for installation, power is hold much larger than wire-break power to wire, construction runs and overhauls convenient and safe, practical.
Accompanying drawing explanation
Fig. 1 is bolt-type strain clamp structural representation of the present utility model, and Fig. 2 is bolt-type strain clamp partial sectional view of the present utility model.
Each Reference numeral is: 1 wire clip body, 2U type bolt, 3 installing rings, 4 hex boltss, 5 wire casings.
Embodiment
In order to more clearly understand above-mentioned purpose of the present utility model, feature and advantage, below in conjunction with drawings and Examples, the utility model is described further.It should be noted that, when not conflicting, the feature in the embodiment of the application and embodiment can combine mutually.
Set forth a lot of detail in the following description so that fully understand the utility model, but, the utility model can also adopt and be different from other modes described here and implement, and therefore, the utility model is not limited to the restriction of the specific embodiment of prospectus below.
Embodiment 1, as shown in Fig. 1 Fig. 2, a kind of bolt-type strain clamp 1 that the present embodiment provides, wire clip body 1 adopts the monoblock cast of aluminium alloy nonmagnetic substance, the through hole communicated up and down is had in wire clip body 1 wiring inlet side, U-bolt 2 inserts through hole inside, hole size matches with U-bolt 2, the bottom of U-bolt 2 is furnished with that nut is in addition fastening (considers that the fastening requirement of wire clamp is different, U-bolt 2 number does not make concrete restriction, be generally 2-5, according to actual needs, also can be multiple; If other structures are identical, and only to the change of U bolt 2 number also in protection range of the present utility model).Between U-bolt 2 and wire, be provided with wire clamp briquetting (not shown), wire clamp briquetting is the elongate configuration of a monoblock, and the length that on length and wire clip body, all U-bolts 2 are side-by-side is suitable.Be provided with installing ring 3 in the side, end of wire clip body 1, opposite side is provided with hex bolts 4, and installing ring 3 and hex bolts 4 are arranged in wire clamp end correspondence, and wire clip body 1 extends to form the outlet of wire at installing ring 3 and hex bolts 4 mid portion.Consider the intensity of whole wire clamp, installing ring 3 and hex bolts 4 are stamped to form with wire clip body 1 entirety.Be provided with wire casing 5 in wire clip body 1 inside, wire clip body 1 top and bottom are struck out curve form, U-bolt 2 faying face is curved surface, and wire is not easy to slide after compacted, thus adds the grip of suspension clamp to wire.Between wire casing 5 and wire, be provided with non magnetic protection tube (not shown), non magnetic protection tube material is rubber, and non magnetic protection tube is close to wire casing 5 inwall, plays the effect of guardwire.
In order to improve stability and the fail safe of hex bolts 4, the bolt pin running through hex bolts is set at the afterbody of hex bolts 4 (not shown, can by through hole reserved for an iron wire inserting bolt afterbody, the then one end bending that then will insert of two bending or iron wire doubling).
In order to reduce wire clip body 1 in use to the extent of damage of wire, bottom wire clip body 1 and top opened extremity be outward extending turnup structure, wire clip body 1 pair of wire reinforce after wire clamp limit leave wire epidermis, wire can be prevented when wind is rocked and wear and tear in wire clip body 1 limit, improve the useful life of wire.
Power is hold in order to what improve wire clip body 1 pair of wire; strip projected parts structure is evenly provided with (not shown inside non magnetic protection tube; bulge-structure also can be flat circle or square); U-bolt 2 and hex bolts 4 fastening after; wire clamp inside is close to the non magnetic protection tube of wire casing 5 inwall and wire compresses; the bulge-structure evenly arranged inside non magnetic protection tube effectively can increase the roughness of contact-making surface; increasing friction force, so increase wire clip body 1 pair of wire hold power.
The above; it is only preferred embodiment of the present utility model; it is not restriction the utility model being made to other form; the Equivalent embodiments that any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as equivalent variations is applied to other field; but everyly do not depart from technical solutions of the utility model content; according to any simple modification, equivalent variations and remodeling that technical spirit of the present utility model is done above embodiment, still belong to the protection range of technical solutions of the utility model.
