Description
Technical field
The utility model relates to a kind of hoisting bracket, relates in particular to a kind of 1000kV extra-high voltage AC circuit strain insulator-string insulation hoisting bracket.
Background technology
UHV transmission line refers to use the circuit of 1000kV and above electric pressure transmission of electric energy.UHV transmission is to develop on the basis of EHV transmission, its objective is continue to improve ability to transmit electricity, realize powerful in, long distance power transmission, and realize remote Power System Interconnection, build up pool.Therefore, changing tension insulator in live line is a big event in the live line working on the extra high voltage line.Traditional changing tension insulator in live line method is mainly blocked the strain insulator monolithic insulator by the insulator closed card tool first, and then utilizes insulation to transmit rope and carry out the transmission of insulator.In the real work, the weight of insulator closed card tool is about 35 kilograms, strain insulator monolithic weight is about 23.5 kilograms, horizontal range between the strain insulator string is approximately 250mm, less than 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 UHV transmission line was changed strain insulator, owing to reasons such as the weight of insulator spacing large and insulator string are little, the live line working personnel can't adopt traditional changing tension insulator in live line method complete operation.The replacing instrument that also is not suitable at present 1000kV extra-high voltage AC circuit strain insulator string.
The utility model content
The purpose of this utility model provides 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 utility model adopts following technical proposals:
A kind of 1000kV extra-high voltage AC circuit strain insulator string insulation hoisting bracket, comprise the triangular supports that is formed by column, hound and singletree, the first end of column and the first end of hound are hinged, the second end of column and the first end of singletree are hinged, the second end of singletree and the second end of hound are hinged, the second end of column and the second end of singletree all are connected with stationary fixture, also are provided with triangle cantilever-rotating hoisting bracket on the described column.
Described triangle cantilever-rotating hoisting bracket comprises suspension bracket stull and suspension bracket diagonal brace, the first end of suspension bracket stull and the first end of column are rotationally connected, the second end of suspension bracket stull and the first end of suspension bracket diagonal brace are hinged, the second end and the column of suspension bracket diagonal brace are rotationally connected, and are provided with lifting eye on the second end of suspension bracket stull.
The second end of described 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 the adjustable steel wire flexible lines.
Described column, hound, singletree, suspension bracket stull and suspension bracket diagonal brace all adopt insulating bar.
The utility model is by being arranged on stationary fixture on the triangular supports that is comprised of column, hound and singletree, can effectively fix the parallel strain insulator string of two strings, again by triangle cantilever-rotating 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.
