Description

A kind of electric force pole tower cross-arm
Technical field
The utility model belongs to field of electrical equipment, is a kind of electric force pole tower cross-arm specifically.
Background technology
Cross-arm is the angle bar that electric pole top is laterally fixed, and has porcelain vase above, is part important in shaft tower, is used for Insulator and gold utensil are installed, to support wire, lightning conducter, and are allowed to keep certain safe distance by regulation.It can divide by material For iron cross arm, porcelain pole arm, composite insulation cross-arm;Cross-arm is divided into 10KV and following circuit cross-arm, such as single pole cross-arm, door by purposes Bar cross-arm, lift load, lead cross-arm etc. and 35KV and Above Transmission Lines assembling cross-arm (straight line, corner and strain insulator) etc..Cross-arm aids in The gold utensil of installation has M iron, cross-arm yoke plate, spike, Qula plate, anchor ear, single head bolt, double-end plug, drift bolt etc..
At present, vertical angle is kept after cross-arm installs between electric pole, and ground is a plane, raining or When snow melting, it is unfavorable for ponding drainage, ponding can be formed on the lower surface of cross-arm, influence to set on cross-arm various Facility.
Utility model content
The utility model purpose be intended to provide it is a kind of it is simple and reasonable, ponding on cross-arm can be drained Electric force pole tower cross-arm.
To realize above-mentioned technical purpose, the technical solution adopted in the utility model is as follows:
A kind of electric force pole tower cross-arm, including two structure identical cross-arm units, described two cross-arm units are symmetrical arranged, And anchor ear is provided between two cross-arm units, described two inside one end of cross-arm unit are fixedly connected respectively at anchor ear both sides, institute Stating cross-arm unit includes T-shaped steelframe, V-shaped groove, and described T-shaped inside one end of steelframe is fixedly connected with anchor ear, the V-shaped groove two The inside side in hypotenuse upper end is equipped with flange, and the flange is fixedly connected in T-shaped steelframe, the outside one end depth of V-shaped groove Less than inside one end depth.
Further limit, the T-shaped steelframe top surface is provided with drainage plate, and the drainage plate middle part raises up and cross section It is equal with T-shaped steelframe top width for isosceles triangle, the drainage plate base width.
Further limit, the anchor ear is annular, and the anchor ear inwall is provided with skid resistant course, the skid resistant course outer wall and anchor ear Inwall is fixedly connected, and the skid resistant course inwall is provided with some compact arranged annular ridges.
Further limit, anchor ear upper end size is less than lower end size.
Using the utility model of above-mentioned technical proposal, two cross-arm units are made up of T-shaped steelframe and V-shaped groove, V-shaped groove two The inside side in hypotenuse upper end is provided with flange, and flange can be fixedly connected with T-shaped steelframe by modes such as screw or welding, T words The inside one end of shaped steel frame is fixedly connected with anchor ear, and anchor ear is used to cross-arm unit and electric pole installation is fixed;Due to T-shaped Steelframe is horizontal after mounting with electric pole, and outside one end depth of V-shaped groove is less than inside one end depth, that is, Say that V-shaped groove is deeper by the depth of anchor ear side, then it is horizontal high highly to will be above inside one end for the outside one end bottom level of V-shaped groove Degree;When there is the rainy day, the ponding on cross-arm will be along V-shaped groove outer wall to V-shaped groove flows, and along V-shaped groove bottom to embracing Side flowing is bound round, will finally be flowed downward along the body of rod of electric pole, can effectively prevent cross-arm bottom surface ponding;T-shaped steel Top of support sets drainage plate, and the ponding on cross-arm surface can be cut and converge at V-shaped groove outer wall, improved horizontal by drainage plate to both sides shunting The anti-ponding effect of load;Skid resistant course is fixedly installed in anchor ear inwall, and skid resistant course can be made using red copper, and its thickness is not more than 3mm, Annular ridge is set in skid resistant course inwall, can effectively improve its skidproof effect;Anchor ear upper end size is rained lower end size, symbol The up-small and down-big architectural feature of the electric wire body of rod is closed, the tight ness rating combined with the electric wire body of rod is improved, is more firmly mounted.
The utility model is compared with prior art, simple and reasonable, ponding on cross-arm can be drained.
