Abstract
The invention relates to one gate emergency repair wire lift structure as power system circuit repair lift wires, which comprises left and right columns and level, wherein, columns and level arm have pulling strengthening one; the said level arm comprises edge arm and middle arm fixed by left and right columns and one temporary beam put down level beam with one end fixed to column and other connected to wire beam to change two columns through wire beam; the said middle level beam is composed of three sections of rack.
Description
Technical field
The present invention relates to be exclusively used in the equipment technical field of installation, maintenance, repairing or dismounting cable or electric wire, especially relate to the lead elevating mechanism for gate emergent repairing tower in the circuit on power system repairing.
Background technology
In electric power system, the accident of falling the shaft tower of overhead transmission line happens occasionally, and causes power failure, and repairing fast restored electricity in the short as far as possible time.And the shaft tower in the transmission line is generally all higher, lift repairing, need have highly equal or higher interim shaft tower to make emergent repairing tower, the shaft tower that also has the temporary transient replacement of the interim shaft tower of direct usefulness to be fallen; Emergent repairing tower commonly used has a type, goes up two kinds of fonts, and gate emergent repairing tower is used more generally; When tower takes place after, three transmission pressures often can not break, when the repairing circuit, need and to be set on the emergent repairing tower with the lead hoisting frame that shaft tower falls down, the phase conductor difficulty is very big in wherein promoting, and does not have the setting of lead elevating mechanism on traditional emergent repairing tower, must increase by two columns that the multilayer temporary guy is reinforced emergent repairing tower, remove cross-arm, middle phase conductor is promoted again and install, cause repairing speed slow, delay restores electricity the time.
Summary of the invention
The objective of the invention is provides a kind of lead elevating mechanism for gate emergent repairing tower for overcoming the deficiency of above-mentioned prior art, can reduce workload in the repairing process, by lifting and lifting lead, realizes Fast Installation, with rapid processing accident recovery power supply.
For achieving the above object, technical solution of the present invention is such: a kind of lead elevating mechanism for gate emergent repairing tower, comprise the gate emergent repairing tower of forming by the cross-arm of the left and right pillar of framework pillar and framework beam type, between left and right pillar and between each column and cross-arm the drag-line reinforcement is arranged, said cross-arm comprises limit cross-arm and middle cross-arm, fix with left and right pillar respectively, it is characterized in that, also comprise an interim crossbeam, this interim crossbeam can place under the cross-arm, one end and column are fixed, and have screw mandrel to connect between the other end and column, can change two column spacings by regulating screw mandrel; Cross-arm is made up of three sections frame girders at least in said, in composition between the adjacent frame beam of cross-arm, by form the detachable connection of two sections frame girders at frame girder termination grafting bearing pin, wherein between the pin shaft hole of bearing pin and two frame girder terminations certain clearance is arranged, cross-arm during each section frame girder fuses at ordinary times and forms, bear gate emergent repairing tower support load during this time, when the screw mandrel of adjusting interim crossbeam, after changing two column spacings slightly, bear the load of middle cross-arm by interim crossbeam, can extract bearing pin this moment from the frame girder termination, make that the frame girder of cross-arm breaks away from mutually in the composition, middle one section frame girder is opened, and the middle phase conductor that is between column can pass through from the cross-arm of opening.
Specific operation process is as follows: erect emergent repairing tower in the transmission line direction, phase conductor is in the door shape inside of emergent repairing tower in this moment, want lead is lifted on the emergent repairing tower, middle phase conductor must pass through the middle cross-arm of emergent repairing tower, lifts then on the insulator of emergent repairing tower; So in lifting, need carry out in two steps during phase conductor, phase conductor rises under the middle cross-arm of emergent repairing tower in promptly first, interim crossbeam is installed again, adjust screw mandrel, load is fallen on the interim crossbeam, taken apart middle cross-arm, lead is risen on the middle cross-arm, cross-arm in the connection, the lifting of phase conductor in finishing.
Other occasions of cross-arm also can be carried out in this way and can operate in lead need pass through.
Since adopted technique scheme, a kind of lead elevating mechanism for gate emergent repairing tower of the present invention, and phase conductor passes through middle cross-arm easily in making, and reduces workload in the repairing process, realizes Fast Installation, with rapid processing accident recovery power supply.
