Abstract
The utility model discloses a pad type suspension clamp used in an overhead power line, and the clamp comprises two petals of suspension clamp bodies mutually cooperated. Each suspension clamp body comprises a suspension part, a lead holding part and a connection part, and the suspension part is provided with an installation hole used for connecting, and the lead holding part is provided with axially communicated grooves. The grooves can form a through hole for clamping a lead when two petals of suspension clamp bodies are closed. The connection part is a gemel positioned on the lower edge of two petals of suspension clamp bodies. The lower edge of two petals of suspension clamp bodies adopts an articulated manner, thereby not only displacing a bolt, but also enabling the suspension clamp body in exact positioning and more convenient installation, and the working efficiency is greatly improved. In order to reduce the hurting to lead surface by metal clamping, the utility model can be provided with a rubber pad in the groove and additionally provided with an aluminum sheet on the internal surface of a conductive pad.
Description
One, technical field
The utility model relates to a kind of suspension clamp that is used for hanging on the overhead power line straight line pole leads such as steel reinforced aluminium conductor, aluminium stranded conductor or ground wire steel strand wire, a kind of specifically liner type suspension clamp.
Two, background technology
Suspension clamp is mainly used in overhead power line, by connecting gold utensil lead, lightning conducter or ground wire etc. is suspended on the straight line pole.Also be used in and support the fixing of transposed conductor and strained angled tower wire jumper on the transposition tower.It mainly adopts tinplate or aluminium alloy to make.
Existing suspension clamp structure mainly comprises the bag type, it is several that two-wire folder is vertically aligned etc., the suspension clamp of these kinds all is the symmetrical structure that adopts two-piece type, need during installation lead is placed the installing hole that forms in the middle of the involutory back of wire clamp, the fastening bolt of both sides locking up and down again, for with firm being fixed on the wire clamp of lead, general wire clamp upper and lower sides all adopts the bolt of many groups to improve reliability, but this has just brought inconvenience for installing, two vertical line heads to be aligned during installation and penetrate bolt again, in case locating inaccurate, both may make lead fixed unreliable, and use bolt fastener not only to increase workload in a large number, reduce operating efficiency, but also increased cost.In addition, because wire clamp is that metal is made, thereby when the clamping lead, can cause lead intensity decreases and transfer rate also influenced in the damage wires surface.
Three, utility model content
The purpose of this utility model is to provide a kind of compact conformation, liner type suspension clamp easy for installation, with low cost in order to solve the prior art problem.
For realizing above-mentioned technical purpose, a kind of liner type suspension clamp described in the utility model, comprise the suspension clamp body that two lobes cooperatively interact, described suspension clamp body is formed by hanging hold with a firm grip position and connecting portion of position, lead, wherein hang the position and be provided with the installing hole that connects usefulness, the lead position of holding with a firm grip is provided with the groove of axial perforation, the involutory rearward recess of two lobe suspension clamp bodies promptly forms a through hole that is used for the clamping lead, it is characterized in that: connecting portion is to be positioned at two lobe suspension clamp body lower edges and hinged hinge.
The lower edge of two lobe suspension clamp bodies is adopted articulated form, not only substituted the bolt of bottom, and hinge also makes between two suspension clamp bodies the location more accurate, install more convenient, only need to place groove that clamping plate are involutory in lead, again bolt is passed upside installation portion installing hole and tighten and get final product, make quick for installation saving trouble, improved operating efficiency greatly.
In order to reduce the infringement of metal clamping to conductive line surfaces, adaptive with it rubber packing can be housed in groove, thereby being evenly distributed on whole conductive line surfaces by rubber packing, the power of clamping plate reduced this infringement.In addition, rubber packing can reduce the static stress of lead on hitch point, improves the antivibration ability of lead, suppresses the dynamic stress of wind-force vibration; Lead is avoided the influence of wearing and tearing and metal fatigue ground under the protection of rubber packing, can also increase the useful life of lead significantly.Rubber packing can use conductive rubber to make, but consider preferably to use common non-conductive rubber from economy, at this moment, in order to prevent to produce induced current or potential difference between electric wire and the suspension clamp, need adopt the aluminium flake that makes electric wire and suspension clamp keep excellent electric contact on rubber packing top.

Five, embodiment
As shown in Figure 1-Figure 3; a kind of liner type suspension clamp described in the utility model; comprise the suspension clamp body that two lobes cooperatively interact; this suspension clamp body is by hanging position 1; hold with a firm grip position 2 and connecting portion 3 of lead formed; wherein hang position 1 and be provided with the installing hole 4 that connects usefulness; the lead position 2 of holding with a firm grip is provided with the groove 5 of axial perforation; adaptive with it rubber packing 6 is housed in groove 5; be provided with the aluminium flake 7 that makes electric wire and suspension clamp keep excellent electric contact at rubber packing 6 inner surfaces; when the involutory rearward recess 5 of two lobe suspension clamp bodies and on rubber packing 6 promptly form a through hole that is used for the clamping electric wire; rubber packing 6 plays the effect of guardwire, and connecting portion 3 is to be positioned at two lobe suspension clamp body lower edges and hinged hinge.
