Description

Conductor wire end tetrad plate special mould clamp
Technical field
The utility model relates to the hot line maintenance field of tool, especially a kind of conductor wire end tetrad plate special mould clamp.
Background technology
In compact transmission line, the division number of lead is different with the conventional line division number, adopts six divisions to arrange usually, on gold utensil model, type of attachment, also exists than big-difference.Wherein, strain tower insulator string conductor wire end is that the simply connected plate laterally connects, and insulator tower head end is that triangle yoke plate list hanging point is connected with body of the tower.Because the safety operation of compact line distance is smaller, in the regional 500kv compact line of particularly high elevation, height above sea level below 1000 meters and 1000 meters and above earth potential and equal potential working minimum safe distance relatively only be 3.2m and 3.4m respectively, alternate minimum safe distance only is 4.6m and 5.0m respectively during equal potential working, therefore, when the insulator string damage needs to change, in order to guarantee safety, usually all be to take the operating type that has a power failure at present, this brings inconvenience to people's life and enterprise's production.
In order under situation about not having a power failure, also to overhaul, change operation, people have made the special-purpose turnover panel jig of tower head end triangle yoke plate: its employing is renovated movable, stress surface is linked into an integrated entity by drift bolt up and down, make things convenient on the tower and assemble, during installation,, jig is stuck on the triangle yoke plate as long as open the jig bolt, allow the king-bolt that connects insulator string and triangle yoke plate place the through hole of jig, bolt is resetted gets final product again.For fear of because of the stressed load tool variations that do not make at grade, turnover panel jig two ends are connected with insulated tension pole with movable lengthening joint, pull bar can arbitrarily be rotated in the horizontal and vertical directions, improved the fail safe and the flexibility of live line working greatly.
But, also do not have conductor wire end instrument matching used at present with it.
The utility model content
The technical problem to be solved in the present invention provides a kind of conductor wire end tetrad plate special mould clamp, is used for changing insulator string under electriferous state to cooperate the special-purpose turnover panel jig of tower head end triangle yoke plate.
Adopt following technical scheme for solving the problems of the technologies described above the present invention: conductor wire end tetrad plate special mould clamp, card, right card and bracing frame in the middle of comprising; Middle card is wedge shape, and the middle part has draw-in groove, and top has through-hole groove and movable guard pin is housed; Right card one end has through-hole groove and movable guard pin is housed, and the other end has draw-in groove and at least three bolts hole are arranged; Bracing frame is L-shaped, and L shaped galianconism plate has the bolt hole with right card coupling, and L shaped long-armed plate has adjusts the hole.
Bolt hole and adjustment hole respectively have four.
Four bolts hole are square arrangement.
The utility model conductor wire end tetrad plate special mould clamp can be used with the special-purpose turnover panel jig of tower head end triangle yoke plate, during operation, be fixed on the tetrad plate, be connected with the special-purpose turnover panel jig of insulated tension pole and tower head end triangle yoke plate through leading screw again, the pulling force that bears when insulator is normally moved is transferred on these two instruments, can loosen and change insulator string under electriferous state.In addition, right card is bolted on the installing hole of grading ring, has increased the air gap, has improved the live line working coefficient of safety, the situation generation of having avoided last a slice insulator to be difficult to deviate from and having resetted; Its height can suitably be adjusted according to strain tower corner situation in the adjustment hole of bracing frame, makes it more can adapt to different angle insulator strings, and the socket-clevis eye bolt is easier to be deviate from.Therefore, use the utility model and make Compact Transmission Line and Its Live Line Work work simpler, light, fail safe is higher.
