Abstract
The utility model relates to a replacing device for an insulator string, in particular to a ground-potential charged replacing device for a linear-tower inversion type hanging-board insulator string. Based on the replacement work of the linear-tower inversion type hanging-board insulator string, the utility model provides a device capable of realizing the ground-potential charged replacing of the tower-shaped insulator string. A T-shaped screw rod card seat is adopted to be installed on the inversed angle steel of a cross arm, realizing the first step of charged operation, namely the fixed supporting of the upper part of the insulator string; next, double lower hooks are adopted; as the tower-shaped insulator string is simultaneously connected with two conducting wires of a tangent tower, in order to ensure stable replacement, the double lower hooks can balance the acting force of the two conducting wires and the insulator string, and the lower supporting work of the charged operation is realized. Thus, by the innovation on the two tools, the charged replacement work of the tower-shaped insulator string is realized, and a series of f economic and social problems brought by power-failure work are avoided.
Description
Technical field
The utility model relates to a kind of more changing device of insulator string, particularly a kind of tangent tower inverted insulator string on attachment plate earth potential live replacing device.
Background technology
The cross-arm of flip-over type tangent tower is to adopt two angle steel upside-down mountings to become
Type, the suspension insulator upper end on the tangent tower hang in the jack on angle steel two vertical planes, and the bottom is directly connected on the lead (line conductor).
Because two angle steel upside-down mountings become
Type, the middle space of reserving is little, to promote lead exactly and change insulator string, dwindle the distance between lead and the cross-arm, the load transfer that insulator string is born is to the instrument of changing, but insulator string charged for replacement device of the prior art can't solve the support problem of upper space, another patented technology (application number: 2008100708700 by applicant's application, name is called: electric replacement device for suspended insulator chain) also can't realize this technical problem, because the hook of first in this technology can't be articulated on the wherein angle steel of upside-down mounting, the open end of hook can't be stretched and is embedded in the middle of two angle steel, if hang on the cross-arm of this tower, just need be across two angle steel, need internal channel to link up with greatly,, improved cost of manufacture though realize easily, and wide groove also brings operational instability, this be in hot line job the hidden danger that should stop; Therefore on the other hand, the insulator string bottom of this turriform is connecting two leads, only adopts single suspension hook to ensure and operationally stablizes feasiblely, and original charged for replacement device can't be applied in the insulator string charged for replacement operation of this tower.At present, the insulator string of this turriform replacing operation can only be based upon on the power failure basis and carry out.

T-shape screw mandrel deck be created to the firm support that tangent tower inverted insulator string on attachment plate is changed provides top, connection and lifting that two suspension hooks down are the bottom have ensured stable and safety, just realized the condition of charged for replacement like this for the insulator string of this turriform, the more changing device of easy operation is provided for the charged for replacement insulator string, ensured carrying out smoothly of charged for replacement operation, having avoided has a power failure operates a series of economy, the social concern of bringing.
The utility model can further be specially:
The top of screw mandrel deck has an opening " U " type stopper slot, and it is positioned at the both sides of symmetry on the deck upper width axis.
When screw mandrel is installed on the screw mandrel deck, the ear shape member inlay card on the screw mandrel in this " U " type stopper slot, thereby define link position between screw mandrel and the screw mandrel deck, the rotation of screw mandrel when preventing to operate.In addition, can also further be specially:
Bilateral symmetry at " U " type stopper slot is distributed with two spacing holes.
When screw mandrel is installed on the screw mandrel deck, and ear shape member inlay card in stopper slot the time, can be passed through this two spacing holes mounting fixing parts, with further fixedly screw mandrel and screw mandrel deck.
The bottom of insulated hanging pole is connected with two suspension hooks down by a kind of securing member.
This securing member can be a kind of high-strength rivet.
Insulated hanging pole can be specially with two suspension hooks down:
The end portion of insulated hanging pole is furnished with a plurality of location holes, and two first suspension hook and second suspension hooks of suspension hook down are installed in respectively in two location holes, and two conductor spacings that the distance of two location holes is connected with insulator string equate.
Can also be:
Two first suspension hooks of suspension hook down are connected by a kind of high-strength securing member with second suspension hook, and its first suspension hook is fixedlyed connected with the bottom of insulated hanging pole by securing member.
Two mouths of hook of suspension hook down are gradually big from inside to outside shape.
Can make things convenient for lead to enter suspension hook like this.
Two suspension hooks down can also be:
Suspension hook includes coupler body and movable fastener, and movable fastener is a kind of carbine spare, and one end and coupler body are hinged, and the other end extends to the hook groove formation of the mouth of hook and coupler body and surrounds shape.
During use, when lead will enter the hook groove, movable fastener can be under the effect of spring, make mouth of hook Zhang Degeng big so that lead enters the hook groove, after lead is in place, the resilience under the prestressing force of spring of movable fastener is surrounded with the hook groove formation of coupler body, guarantees that lead can firmly be hung in two suspension hooks down.
In sum, replacing operation based on tangent tower inverted insulator string on attachment plate, the utility model provides a kind of earth potential live replacing device of realizing above-mentioned turriform insulator string, adopted a kind of T-shape screw mandrel deck, on the angle steel that is installed in upside-down mounting on the cross-arm, realize the first step of hot line job, it is the fixed support of insulator string top, next has adopted two suspension hooks down, because the insulator string of this turriform is connecting two leads of tangent tower simultaneously, the stable guarantee of changing for guaranteeing can balance two leads and the active force of insulator string with two suspension hooks down, the lower support operation of realization hot line job; Thus,, finish, realized charged for replacement operation, a series of economy, the social concern of having avoided the power failure operation to bring this turriform to the more integral body creation of changing device of tangent tower inverted insulator string on attachment plate by innovation to top two kinds of instruments.
