Abstract

The utility model discloses a V-shaped insulator chain ground potential electrification replacing tool, which comprises a front block, a back block, a lead screw and a pulling plate. A blocking slot capable of being blocking on a jointing plate is arranged on the front block and the back block respectively. A bottom of the blocking slot is inclined from the front to the back, and a slot depth of the front block is larger than the slot depth of the back block. A slot capable of being blocked into a socket is arranged in the front of the front block, and an operating ring which can be operated by an insulating operation rod is arranged on the front block. Insulator cradle fixing holes and nut lead screw fixing holes are arranged on two flanks arranged on the back block in parallel. A slot capable of being blocking on a draw bar and a hanging bar is arranged on one side of the back block. The V-shaped insulator chain ground potential electrification replacing tool has the advantages of being safe and firm, wide in applicable scope of achievable ground potential working, and convenient to operate.

Description

V word insulator chain ground potential charged for replacement instrument
Technical field
The utility model relates to a kind of live line working Work tool, particularly a kind of V word insulator chain ground potential charged for replacement instrument.
Background technology
Because part 220KV circuit adopts compact shaft tower (as the 2202DZMV type), lead adopts " V " word insulator string pattern to connect in the tangent tower, and it is not vertical ground that the little and insulator string of combinational gap is subjected to force direction.As if the earth potential method of employing tradition replacing suspension insulator, past wherein insulator one lateral deviation of one side lead meeting is moved, stability can not be guaranteed well, and lead side spring catch is difficult to taking-up on the other hand; If adopt the equal potential working combinational gap can't meet the demands again.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of charged for replacement instrument of realizing earth potential live replacing V word insulator string is provided.
A kind of V word insulator chain ground potential charged for replacement instrument comprises preceding card, back card, screw mandrel and arm-tie, and its structural feature is:
Draw-in groove on the be stuck in yoke plate that the described preceding draw-in groove that blocks the middle part is a strip, the bottom land of described draw-in groove is for to be tilted rearwards by the front, the groove depth of card front is less than the groove depth of back before being positioned at, be provided with the groove that can snap in the bowl head in the front of preceding card, the connector that after the bottom of draw-in groove two sides is provided with connection draw-in groove two sides preceding card to be stuck in bowl head place slot opening is pinned also is provided with the operation ring that available insulating bar is operated on preceding card;
On two flanks of back card, be set side by side with bottle supporting frame fixing hole and nut screw mandrel fixing hole, side at back card is provided with the groove that can be stuck in pull bar and link plate, the groove of back card also be provided with the communication groove both sides can after snap in pull bar and link plate after with the connector of slot opening pinning.
V word insulator chain ground potential charged for replacement instrument of the present utility model, in use, the groove that preceding cartoon is crossed on a draw-in groove and the side is stuck between LV yoke plate and the socket-clevis eye, utilizes socket-clevis eye place bolt as lead side fulcrum.With the draw-in groove of back card then the groove on the side be stuck between pull bar and the P type link plate, utilize P type link plate as cross-arm side fulcrum; After installing forward and backward card, again the connector on it is connected the two sides of forward and backward card groove, to prevent that forward and backward card is from corresponding yoke plate, bowl head or pull bar, link plate landing, to play the effect of lock or safety bolt.Then adopt double lead, two arm-tie to connect again, can realize earth potential replacing insulator string.
Described connector or be pin or for bolt.
In sum, the following compared to existing technology advantage of the utility model:
1, safety is firm.Adopt this instrument to change the loading that " V " word insulator string can realize replacing fully with the tool direction size insulator string, avoid adopting the vertical ground direction to promote the bad problem of lead stability.
2, realize that earth potential working is applied widely.Card can be implemented in the earth potential working of lead employing " V " word insulator string charged for replacement in the compact straight line pole before the new development tool, and job area is wide.
3, simple to operate.Operation sequence is simple, and its method of operation just can be operated as long as the personnel of meeting live line working do to understand slightly on the spot to similar with aerofoil profile card replacement strain insulator string.
