Technical field
The utility model relates to changes insulator protection card field, specifically refers to a kind of replacing 110kV strain insulator list insulator string backup protection jig.
Background technology
at present when charged for replacement 110kV power circuit strain insulator list insulator string; the jig of main employing leading screw and screw formula retraction assemblies; this jig mainly comprises that cross-arm side jig, side of wire jig and two ends are articulated with the leading screw at cross-arm side jig and side of wire jig two ends and screw formula retraction assemblies respectively, its cross-arm side jig is split type; it is matched with cross arm side hardware fitting hanging point with symmetrical die cavity by two separation; retraction assemblies is that double-end lead-screw and insulation pull-rod connect to form, and does not have backup protection measure.During operation; two clamping plate of cross-arm side jig are successively connected on cross arm side hardware fitting hanging point; the die cavity of side of wire jig snaps onto on the screw of right angle link plate; then the metal double-end lead-screw in operation retraction assemblies and insulator string are at same plane; and lay respectively at the both sides of insulator string; because this jig does not have backup protection measure, whole strain clamp in use likely can be caused to lose efficacy.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of changes 110kV strain insulator list insulator string backup protection jig, to come off the problem causing jig to lose efficacy in insulation pull-rod with the strain clamp double-end lead-screw when changing insulator overcoming existing 110kV.
The technical scheme in the invention for solving the above technical problem is: change 110kV strain insulator list insulator string backup protection jig; block before comprising backup protection; before backup protection, one end of card has open fixing hole; bandlet is located in fixing hole; a termination of bandlet is fixed on one end of bandlet frame; bandlet frame offers through hole; through hole is provided with bandlet axle; another termination of bandlet is arranged on bandlet axle, and the other end of described bandlet frame is provided with the angle steel hook card for matching with the angle steel on steel tower.Existing jig is in clamping process, double-end lead-screw can come off in insulation pull-rod, cause jig to add when changing insulator to lose efficacy, before backup protection of the present utility model, one end of card is connected with the joint on electric wire, the other end offers the through hole for wearing bandlet, bandlet can move in through hole, a termination of bandlet is fixed on bandlet frame, another termination is arranged on bandlet axle, bandlet axle can rotate around self axle on bandlet frame, realize the mobile of bandlet by the rotation of bandlet axle to shrink, and then regulate the length of whole backup protection card, because bandlet is fixed on bandlet frame and bandlet axle, therefore the problem that there will not be bandlet to come off to cause backup protection card to lose efficacy, angle steel hook card coordinates with angle steel backup protection to link and is connected on cross-arm, the utility model bandlet substitutes traditional double-end lead-screw constriction device, the strain clamp overcoming existing 110kV double-end lead-screw when changing insulator comes off the problem causing jig to lose efficacy in insulation pull-rod.
Further, the other end of described bandlet frame is set to U-shaped clamping plate, two side plates of U-shaped clamping plate all offer the through hole I for fixing fixed axis, one end of angle steel hook card is provided with the screwed hole coordinated with through hole I, is located in through hole I, screwed hole is fastened in U-shaped clamping plate by angle steel hook by fixed axis.Angle steel hook card can rotate around fixed axis, therefore, realizes by rotating angle steel hook card the movement that backup protection is stuck in cross-arm diverse location.
Further, angle steel hook card is vertically installed with the fastening bolt coordinated with angle steel, and the end of fastening bolt is provided with snap fit.Snap fit can axially moving at fastening bolt, and then backup protection card of the present utility model can be connected on the cross-arm of different size, increases the scope of application of backup protection card.
Further, on bandlet frame, also symmetry offers two through holes II, bandlet axle offers the through hole III coordinated with through hole II, is equipped with bolt in through hole II, through hole III.Bolt the stability that can increase bandlet axle is set, make it not easily to loosen, thus avoid the natural shrinking of bandlet, improve the stability maintenance of whole backup protection card.
Further, the contact-making surface of fixing hole and bandlet is arc surface.Arc surface has less resistance, is convenient to the mobile contraction of bandlet in through hole.
To sum up, the beneficial effects of the utility model are:
1, the utility model bandlet substitutes traditional double-end lead-screw constriction device; because bandlet to be fixed on before backup protection on card, bandlet frame and bandlet axle; make whole backup protection card as a whole, the problem causing jig to lose efficacy in insulation pull-rod therefore the strain clamp double-end lead-screw when changing insulator that there will not be bandlet to come off to cause problem that backup protection card lost efficacy to overcome existing 110kV comes off.
2, the utility model is set to U-shaped clamping plate by bandlet frame and angle steel hook are linked the one end connect, and is arranged in U-shaped clamping plate by angle steel hook card by fixed axis, realizes the movement that backup protection is stuck in cross-arm diverse location.
3, the utility model by being vertically installed with the fastening bolt coordinated with angle steel on angle steel hook card, and the end of fastening bolt is provided with snap fit, increases the scope of application of backup protection card.
4, the utility model by arranging bolt on bandlet axle, improves the stability maintenance of whole backup protection card.
5, the utility model is by being arc surface by the contact-making surface of fixing hole and bandlet, makes the movement of bandlet more convenient.
