Abstract
The utility model discloses a preformed suspension clamp. The suspension clamp is formed by a left body, a right body, a U-shaped hoop fastener and a bolt. The bodies are in the shape of semicircular tiles. The left body and the right body are combined oppositely to form a wire placement channel. A hanger part above the bodies is designed to be in the shape of a trapezoid and forms large arc transition connection with the semicircular tiles. The left body and the right body form a ring by means of the U-shaped hoop fastener and are fixed by the bolt. The suspension clamp is reasonable in structure, easy to install, long in service life, low in energy consumption, and small in electric corona.
Description
Technical field
The utility model relates to a kind of overhead transmission line overhanging golden tool, relates in particular to a kind of special pre-hinged catenarian cable cleat.
Background technology
Suspension clamp is as one of the gold utensil of use amount maximum on power overhead network, and its security reliability is significant to power line line security and electric power safety.In the pre-hinged catenarian cable cleat structure now using at present, mostly be hinge type and hood type, hinge type intensity is lower, easily produce the defects such as corona, and general hood type easily stretches elongatedly hanging stressed rear anchor ear, and strength decreased, easily produces the defects such as corona.
Utility model content
The purpose of this utility model is to provide a kind of rational in infrastructure, easy for installation, long service life, energy consumption is low, corona probability is low pre-hinged catenarian cable cleat.
To achieve these goals, the utility model adopts following technical scheme: it is made up of left and right two bodies and U-shaped anchor ear fastener and bolt, described body is semicircle tile shape, the involutory rear formation lead placement groove of left side body and the right body, described left side body and the right body by U-shaped anchor ear fastener around and be bolted.
The hangers portion of described body top is designed to trapezoidal and is connected with the transition of semicircle tile formation orthodrome.
Described hangers portion and body junction are provided with reinforcement.
Described body below is provided with positioning boss.
Described shirt rim, body two ends is designed to circular arc convex.
Described U-shaped anchor ear fastener top is provided with pair of bolts fixing hole, and bottom has location hole.
The beneficial effects of the utility model:
1, overcome hood type suspension clamp because the extension elongation of long-time running anchor ear makes its strength decreased, caused between housing and preformed armor rods loosening and wear and tear.
2, the trapezoidal design of hangers portion being connected with the orthodrome transition of semicircle tile portion.Strengthen mechanical strength, eliminated stress concentration point, made product use safety and reliability.
3, reasonable, easy for installation, the long service life of project organization, the feature such as energy consumption is low, corona is little.

Embodiment
A kind of pre-hinged catenarian cable cleat as shown in Figure 1, it is made up of left and right two bodies 1 and U-shaped anchor ear fastener 2 and bolt 3, described body 1 is semicircle tile shape, the involutory rear formation lead placement groove of left side body 1 and the right body 1, described left side body 1 and the right body 1 by U-shaped anchor ear fastener 2 around and fixed by bolt 3.
Referring to Fig. 2, the hangers portion 4 of described body 1 top is designed to trapezoidal great circle arcuation and forms orthodrome transition with semicircle tile 12 be connected, so just eliminate stress concentration point, described hangers portion 4 is provided with reinforcement 5 with clamp body 1 junction, strengthen like this holding capacity of wire clamp, stressed strength increase, change stress curve, when being subject to unbalanced load, wire can shield better, described body 1 below is provided with positioning boss 7, in order to coordinate U-shaped anchor ear fastener 2 to assemble, in the time that hanging conductor clamp is stressed, can effectively carry the extension elongation producing because of stressed, thereby make suspension clamp strength increase, extend useful life, described body 1 shirt rim, two ends 6 is designed to circular arc convex, can effectively reduce the loss producing because of corona by cambered surface transition, reduce the generation of electric arc, play the effect of energy-saving consumption-reducing.
Referring to Fig. 3, be provided with positive stop lug boss 10 at body 1 inside front, after a whole set of suspension clamp installs, can effectively prevent the phenomenon appearance of pine excessively of bolt 3 tensions, tension can make intermediate plate compress distortion, so that preformed armor rods and auxiliary equipment distortion, cross pine and can make poor fit between body and preformed armor rods, thereby friction was for a long time lost efficacy a whole set of suspension clamp.
Referring to Fig. 4, described U-shaped anchor ear fastener 2 tops are provided with pair of bolts fixing hole 8, and bottom has location hole 9, and the boss 7 on when assembling and both sides body 1 matches.
Above embodiment is only in order to illustrate the utility model and the described technical scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can modify or be equal to replacement the utility model; And all do not depart from technical scheme and the improvement thereof of spirit and scope of the present utility model, all should be encompassed in claim scope of the present utility model.
