Description
Technical field
The present invention relates to the built on stilts installation device fields of electric wire or cable, are shared in particular to a kind of band electromigration
The auxiliary device of corridor straight line pole.
Background technology
Line corridor refers to the occupied land area in the path of overhead transmission line and area of space.
In order to ensure line insulation intensity and avoid the Danger Electric shock risk to the person and the objects such as surface structures, and prevent quiet
Electric field, at physiology and ecological hazard, is in around the conducting wire under high voltage to conducting wire and nearby artificial, also needs to keep necessary
Clear space region.High pressure overhead power line will produce induced electrostatic field in Earth Surface, for by this electrostatic induction electric-field strength
Degree is attenuated to the degree that will not jeopardize personal safety, and conducting wire necessarily requires to be suspended in due height.
With the raising of transmission line of electricity voltage class, the range of line corridor is significantly expanded.Such as single time 500 kilovolts it is super
Ultra-high-tension power transmission line, shaft tower height is generally up to 30 meters, about 45 meters of line corridor width.Therefore, busy line corridor becomes
Develop one of the difficulty of overhead transmission line.
Due to power transmission line corridor anxiety, 10kV overhead transmission lines in part are taken and 35kV or higher voltage grade circuit at present
It shares corridor and mostly uses double back, the more times erection modes joint used.It is total for 35kV or 110kV and 10kV overhead transmission lines
With the circuit of line corridor, when being migrated to 10kV double circuits on same tower or with more times straight line poles of bar, because of top high-voltage line
Arm of crane cannot be introduced between road safe distance problem, 10kV and 35kV (higher voltage grade) circuit.
The method of the such electric pole of conventional belt electromigration is to remove shaft tower after conducting wire is sling enough height by crane to organize to stand
Enough working spaces are createed.The group of dismounting and new electric pole that old electric pole is completed below 10kV conducting wires stands work.And
Under the premise of sharing corridor with 35kV or 110kV, due to lifting operation narrow space, the lifting of 10kV conducting wires is cannot achieve, therefore
It can not complete the such electric pole work of band electromigration.

End is fixed with wire fixing device 3；
As shown in Fig. 2, straight line cross-arm clamping portion is c-type, including level board I 4, level board II 5 and riser 6, I He of level board
Level board II is parallel, and one end of level board I is fixed on crossbeam, and the other end is connect with level board II by riser, due to angle steel
Horizontal part to be inserted into level board I, the groove that level board II and riser surround, therefore the height of riser is greater than angle steel steel plate
Thickness, the distance between II nearly crossbeam end of level board and crossbeam are greater than the width of angle steel horizontal component；
As shown in figure 3, wire fixing device includes fixed column I 7, fixed column II 8 and automatic blocking plate, fixed column II is pushed up
End is provided with groove 11, and automatic blocking plate is positioned in groove to be hinged with fixed column II, and automatic blocking plate includes left plate 9 and right panel
10, the angle between left plate and right panel is obtuse angle, and the weight of right panel is more than the weight of left plate, and under non-working condition, left plate is on the right side
Substantially horizontal attitude is kept under the gravity of plate, between fixed column I and fixed column II, the length of left plate, which is less than, fixes
The distance between column I and fixed column II.
The auxiliary device uses insulating resin.
As shown in figure 4, included the following steps using above-mentioned auxiliary device migration straight line pole,
The auxiliary device is first installed on the straight line cross-arm both ends of old shaft tower, straight line cross-arm is made to be caught in straight line by the first step
