Description
Technical field
The utility model relates to and a kind ofly is used for overhead transmission line and is exclusively used in the charged power tool that changes suspended insulator chain, particularly a kind of electric replacement device for suspended insulator chain of and two connecting plate clampings.
Background technology
A kind of suspended insulator chain of the prior art more changing device by wire grip, last anchoring jig, insulated tension pole and following suspension hook are formed, wire grip is a kind of screw mandrel wire grip, has a horizontal spanner, last anchoring jig is made up of a kind of L shaped plate and a kind of bolt group, the cross-arm of shaft tower upper support insulator string is generally formed by the angle steel framework, this bolt can pass the hole on L shaped plate and the cross-arm angle steel, thereby the anchoring jig connects with the fastening of cross-arm in the realization, last anchoring jig is fixed on the bottom of wire grip, spanner is positioned at the top of anchoring jig, wire grip lower end and insulated tension pole are affixed, and following suspension hook is fixed on the bottom of insulated tension pole.During operation, operating personnel must move insulator string top from cross-arm, will go up that the anchoring jig is fastening to be connected on the cross-arm angle steel, and following suspension hook links lead simultaneously, with regard to the near operation spanner with the insulator string that relaxes.Owing to need to move the insulator string top from cross-arm, anchoring jig and with regard to the near operation spanner in the fastening nearby connection, therefore, brought difficulty for the charged for replacement insulator string, under the not enough situation in safe space above the insulator string, in fact can't carry out charged for replacement, and operating process is complicated.The most important thing is, under the situation that two insulator string strings are assembled side by side, because connection gold utensil-two connecting plate by upper and lower side between the insulator string is connected in parallel, must use two secondary this more changing device apportions in the outside of insulator string, lax simultaneously two insulator string strings could implement to change operation.Like this, outfit is more, has further aggravated to change the difficulty of operation simultaneously.
The utility model content
The purpose of this utility model is to overcome weak point of the prior art, but and a kind of charged for replacement insulator string is provided, the simpler again and single pair of operation simultaneously can be changed operation and electric replacement device for suspended insulator chain two connecting plate clampings.
The purpose of this utility model realizes by following approach.
Electric replacement device for suspended insulator chain with two connecting plate clampings, comprise wire grip, last jig, insulated tension pole and following suspension hook, wire grip has a horizontal spanner, insulated tension pole is connected with following suspension hook, insulated tension pole also is connected with wire grip and last anchoring jig simultaneously, its structural feature is: going up jig is a kind of bent plate card, it comprises right card and left side card, left side card is a kind of opening fork-shaped, fork pockets thickness is greater than the thickness of two connecting plates, fork laterally is penetrated with a kind of bayonet lock can overlap the pin-and-hole that is inserted in wherein, the pin-and-hole back segment also is provided with a kind of second connecting portion that can be operatively connected with the live line working action bars, right card is connected with wire grip, also is provided with a kind of first connecting portion that can be operatively connected with the live line working action bars on wire grip or the bent plate card.
Like this, during operation, operating personnel needn't move the insulator string top from cross-arm, the live line working action bars that at a distance just can use on shaft tower will whole more changing device hangs above the insulator string and is inserted in bent plate card left side card fork pockets cover on two connecting plates and bayonet lock is overlapped in the insertion pin-and-hole by second connecting portion with the live line working action bars simultaneously, can on two connecting plates, be processed with pin-and-hole, like this, bayonet lock also can pass this pin-and-hole simultaneously, can not want the pin-and-hole on two connecting plates yet, at this moment this bayonet lock can be stuck in the bottom side of two connecting plates.Because the left side card fork end and two connecting plate prism cards touch, thereby realize bent plate card and the clamping firmly of two connecting plates.Following suspension hook hangs and connects lead, uses action bars remote operation wire grip pinch bar, can realize the insulator string that tightens up the work of lead and can relax close insulated tension pole.Because the whole operation process all can be than the operation of the safety zone of distant location, therefore, can the charged for replacement insulator string, and only need a pair more changing device can change operation to the wherein row insulator string of two strings in side by side.
