Abstract
The utility model relates to a maximum concentrated load testing device for a cable support, which is used for testing the maximum concentrated load of the cable support. The cable support comprises an upright column and a support arm. The testing device comprises an L-shaped support, a tension meter, a turn buckle and a steel cable, wherein the upright column of the cable support is fixed on the side wall of the L-shaped support, one end of the tension meter is fixed at the bottom part of the L-shaped support, and the other end of the tension meter is connected to the end part of the support arm of the cable support through the turn buckle and the steel cable sequentially. Compared with the prior art, the maximum concentrated load testing device for the cable support is simple in structure, easy to manufacture and convenient to operate, only needs to be operated by workers, does not need precise equipment, and has a wide range of application.
Description
Technical field
The utility model relates to the load test device, especially relates to the maximum load proving installation of a kind of cable bearer.
Background technology
In transformer station's cable floor, cable duct, cable tunnel and other power cable structures, be used for supporting the support with attached cable, installation and operation has very important effect to cable.All adopt the steel construction cable bearer in the common engineering.There is following subject matter in the steel construction cable bearer: (1) easy-to-rust.The steel construction cable bearer antirust, chemical resistance is relatively poor, especially at wet environment, in the cable duct and cable worker well of long-term ponding, the corrosion of steel construction cable bearer is very fast, even through zinc-plated processing, also suffers corrosion unavoidably.Usually steel bracket needed repairing maintenance once in per 5～7 years.(2) be used for high voltage single-core cable, when cable jacket damages, may form ground connection circulation or produce gap discharge by steel structure support, cause cable jacket further to damage.(3) high pressure list core electric cable with large cross-section, be in operation because the effect of alternating electromagnetic field, can produce tangible eddy current loss and magnetic hysteresis loss at electroconductive magnetic medium steel construction cable bearer, cause backing temp to raise, thereby the cable jacket surface temperature is raise, the medium thermal resistance increases on every side, influences the cable transmission capacity.
Therefore, some present cable beareves adopt compound substance to make, before composite material cable rack is used, need its mechanical property and maximum load are test, have only the cable bearer by mechanical properties test and the check of maximum load just can be applied in transformer station's cable floor, cable duct or the cable tunnel.
The utility model content
The purpose of this utility model is exactly to provide a kind of simple in structure, easy to operate cable bearer maximum load proving installation for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
The maximum load proving installation of a kind of cable bearer, the maximum load that is used for the test cable support, described cable bearer comprises column and trailing arm, this device comprises L bracket, tautness meter, flower basket bolt and cable wire, the column of described cable bearer is fixed on the sidewall of L bracket, described tautness meter one end is fixed on the bottom of L bracket, and the tautness meter other end is connected the trailing arm end of cable bearer successively by flower basket bolt and cable wire.
The column of described cable bearer is by on the sidewall that is bolted to L bracket.
Contiguous block is fixedly arranged at the bottom of described L bracket, and this contiguous block top is annular connecting link, and this annular connecting link is connected with an end of tautness meter.
This device also comprises dip stick, and described dip stick vertically is located at the rear of cable bearer.
When using device of the present utility model, can control the size that the trailing arm end of cable bearer is subjected to steel cable stretching force by adjusting flower basket bolt, the size of this pulling force shows by tautness meter.When cable bearer is carried out maximum load test beginning, earlier flower basket bolt is transferred pine, make the trailing arm end of cable bearer not be subjected to the pulling force of cable wire, tighten flower basket bolt then gradually, the tension cable wire, make the trailing arm end of cable bearer be subjected to load continuously, show the pulling force size by tautness meter, when cable bearer sends when tearing, the pulling force that tautness meter shows is the maximum load that cable bearer can bear, can the amount of deflection of test cable support when being subjected to maximum load by the dip stick at cable bearer rear.
Compared with prior art, the utlity model has following advantage:
1, the utility model is simple in structure, makes easily;
2, the utility model is easy to operate, as long as manually-operated does not need accurate equipment;
3, the utlity model has range of application widely.
