Description
Technical field
The utility model discloses a kind of additive wire supporting insulator, specifically, relate to the additive wire supporting insulator that a kind of electrification railway contact net is used.
Background technology
The safe operation of electrification railway contact net is by using insulator to be achieved on the return wire of additive wire.The insulator mounting means of additive wire return wire mainly is by propping up at angle steel pin insulator or suspension insulator to be installed on the supporting shoulder stand at present.Pin insulator need be fixed on the additive wire by wire rod or preformed wire clamp colligation, and there is certain potential safety hazard in the poor reliability that insulator is connected with additive wire.Suspension insulator need be suspended on it on additive wire by baroque coupling, because the coupling complex structure, the space that the installation insulator needs is bigger, is subjected to the restriction of pillar height and structure space easily.More than the installation of two kinds of insulators all be restricted, can not play the function of protection thunder and lightning effectively, have the potential safety hazard of clamping shakiness, and an installation and maintenance trouble, can not satisfy the requirement that general speed and high-speed electric railway are installed and used insulator.
The utility model content
The purpose of this utility model is: provide a kind of clamping firmly, can effectively play the effect of protection thunder and lightning, additive wire supporting insulator convenient for installation and maintenance.
The utility model realizes that the technical scheme of above-mentioned purpose is:
A kind of additive wire supporting insulator, comprise the insulator 1 that has the full skirt that insulate, the two ends up and down of insulator 1 are fixedly connected with metal-ware 3 and following metal-ware 2 respectively, it is characterized in that: the described metal-ware 3 that goes up is made up of two metal splints 301,302, metal splint 301 is fixedly connected on the upper end of insulator 1 by metal mainstay 303, metal splint 301,302 is connected by bolt 304, metal splint 301, the 302 corresponding arc grooves that are provided with, form the wire casing 305 of about one perforations, two ends one-tenth horn mouth shape, pass through for the annex lead.
The described corresponding profile of tooth groove that is provided with in junction of going up metal-ware 3, following metal-ware 2, insulator 1, last metal-ware 3, following metal-ware 2 are connected the two ends up and down of insulator 1 respectively by the profile of tooth groove.
Described junction of going up metal-ware 3, following metal-ware 2 and insulator 1 fixes by bonding agent, to increase the fastness that insulator is connected with annex.
Compared with prior art the beneficial effects of the utility model are: additive wire insulator of the present utility model, metal-ware by insulator and two ends connection up and down thereof is formed, wherein going up metal-ware is made up of two metal splints, the arc groove that is provided with between two metal splints forms and connects the wire casing that clamping plate two ends, port become the horn mouth shape, passes through for additive wire.It is good that arc wire casing of the present utility model is held action effect to adding of additive wire; the wire casing two ends become the horn mouth shape; additive wire can be by scratch; the following annex of the utility model additive wire insulator can be connected by bolt on the capital or shoulder frame of pillar forms such as prestressed concrete pillar, steel column; fitting limit is extensive; can effectively take into account the lightning protection effect of lightning conducter, not need to increase the pillar height and can effectively protect Catenary Fittings and equipment.The utility model is simple in structure, and is reasonable in design, can effectively take into account lightning protection, and operation is convenient, easy installation and removal, and versatility is good, and applicability is strong, and is safe and reliable, can be widely used in the construction of general speed and high-speed electric railway.
