Abstract

The invention discloses an insulating hoisting bracket for a strain insulator string of a 1000kV extra-high alternating current line. The insulating hoisting bracket comprises a triangular bracket including a stand column, a diagonal bar and a spreader bar, the first end of the stand column is hinged with the first end of the diagonal bar, the second end of the stand column is hinged with the first end of the spreader bar, the second end of the spreader bar is hinged with the second end of the diagonal bar, the second end of the stand column and the second end of the spreader bar are both connected with a fixed clamp, and the stand column is further provided with a triangular cantilever rotating and hoisting bracket. The insulating hoisting bracket can effectively fix two parallel strain insulator strings by installing the fixed clamp on the triangular bracket including the stand column, the diagonal bar and the spreader bar, and hoist the two strain insulator strings to a construction position with a hoist through the triangular cantilever rotating and hoisting bracket, thus being simple in structure and easy to realize, improving the working efficiency, lowering the working intensity of overhead operators, and being convenient for the overhead operators to hoist and install the strain insulator strings.

Description

1000kV extra-high voltage AC circuit strain insulator string insulation hoisting bracket
Technical field
The present invention relates to a kind of hoisting bracket, relate in particular to a kind of 1000kV extra-high voltage AC circuit strain insulator-string insulation hoisting bracket.
Background technology
UHV transmission line is meant the circuit that uses 1000kV and above electric pressure transmission of electric energy.UHV transmission is on the basis of EHV transmission, to develop, and its objective is continue to improve ability to transmit electricity, realize powerful in, long distance power transmission, and realize that remote electric power system is interconnected, build up pool.Therefore, the charged for replacement strain insulator is a big event in the live line working on the extra high voltage line.Traditional charged for replacement strain insulator method, strain insulator monolithic insulator blocks through insulator enclosed jig in main elder generation, and then utilizes insulation to transmit rope and carry out the transmission of insulator.In the real work; The weight of insulator enclosed jig is about 35 kilograms; Strain insulator monolithic weight is about 23.5 kilograms; Horizontal range between the strain insulator string is approximately 250mm, and less than the structure height and the disk track of strain insulator monolithic, the strain insulator monolithic can not carry out extraction work from the centre of insulator string.When on UHV transmission line, changing strain insulator, owing to reasons such as the weight of insulator spacing big and insulator string are little, the live line working personnel can't adopt traditional charged for replacement strain insulator method complete operation.The replacing instrument that also is not suitable at present 1000kV extra-high voltage AC circuit strain insulator string.
Summary of the invention
The purpose of this invention is to provide a kind of 1000kV extra-high voltage AC circuit strain insulator string insulation hoisting bracket, can make things convenient for the work high above the ground personnel that strain insulator string is lifted by crane and installs.
The present invention adopts following technical proposals:
A kind of 1000kV extra-high voltage AC circuit strain insulator string insulation hoisting bracket; Comprise the triangular supports of forming by column, hound and singletree; First end of column and first end of hound are hinged, and second end of column and first end of singletree are hinged, and second end of singletree and second end of hound are hinged; Second end of column and second end of singletree all are connected with stationary fixture, also are provided with triangle cantilever rotation hoisting bracket on the described column.
Described triangle cantilever rotation hoisting bracket comprises suspension bracket stull and suspension bracket diagonal brace; First end of suspension bracket stull and first end of column are rotationally connected; Second end of suspension bracket stull and first end of suspension bracket diagonal brace are hinged; Second end and the column of suspension bracket diagonal brace are rotationally connected, and second end of suspension bracket stull is provided with lifting eye.
Second end of said singletree is provided with length adjustment device.
Described length adjustment device adopts the length adjustment screw.
Described stationary fixture comprises the hard anchor clamps, and the below of hard anchor clamps is provided with scalable steel wire flexible lines.
Described column, hound, singletree, suspension bracket stull and suspension bracket diagonal brace all adopt insulating bar.
The present invention can fix the parallel strain insulator string of two strings effectively through stationary fixture being arranged on the triangular supports of being made up of column, hound and singletree, again through triangle cantilever rotation hoisting bracket; Use lifting appliance that the parallel strain insulator string of two strings is winched to construction location; Simple in structure, be easy to realize, greatly improved operating efficiency; Reduce work high above the ground personnel's working strength, made things convenient for the work high above the ground personnel that strain insulator string is lifted by crane and installs.
Description of drawings
