Abstract
The utility model relates to the technical field of maintenance and overhaul of overhead transmission line in power industry, in particular to a synthesized insulator end clamp. In the power system, the hanging metal tool of the overhead transmission line synthesized insulator is aged and cracked, which causes severe accidents such as disconnection, collapse and the like; and the working quantity is large, which causes slow rush-repair speed when the traditional hoisting chain method is used for replacing the hanging metal part. The synthesized insulator end clamp consists of lifting devices and an end closed clamp; the lifting device consists of a clamping plate, a leading screw, and a screw adjusting component and is fixed on an iron tower cross arm; a metal rod which is arranged at the upper end of the synthesized insulator is fixed in the clamping hole of the end closed clamp; two ends of the end closed clamp are respectively fixed at the lower ends of the leading screws of the two lifting devices by bolts so as to transfer the load of the hanging metal part at the end of the synthesized insulator to the synthesized insulator end clamp to carry out the operation of replacing the hanging metal part. The synthesized insulator end clamp overcomes the shortages of the prior art, reduces the working quantity and shortens the operation time.
Description
Technical field
The utility model relates to power industry maintenance, repair overhead transmission line equipment technical field, specifically a kind of synthetic insulator end jig.
Background technology
At present, in the electric power system, overhead transmission line gold utensil synthetic insulator hangs on the iron tower cross-arm by the hanging point gold utensil, during synthetic insulator upper end gold utensil shape, the Metallic rod top is a bowl head, the Metallic rod diameter is less than a bowl diameter, form an annular boss between Metallic rod and the bowl head, there is a cavity bowl inside, the bulb of hanging point hardware ball-head ring snaps in the cavity of bowl head synthetic insulator is sling, in case occur because of hanging point hardware ball-head ring, U type link plates etc. are aging, problems such as fracture will cause to go offline, the safe operation that jeopardizes overhead transmission line takes place in the serious accident such as tower that falls.Because the body of the tower in the transmission line is generally higher, in the repairing process, in limited interruption duration, use traditional " chain sling method " to change the hanging point gold utensil, because workload is big, personnel, the instrument of input are many, be difficult to satisfy need of work, cause repairing speed slow, delay restores electricity the time, makes troubles for people's the life and the production of enterprise.
Summary of the invention
The purpose of this utility model provides a kind of synthetic insulator end jig, overcome the deficiencies in the prior art, can when transmission line power failure or live line working, change in maintenance, maintenance and the repairing process of synthetic insulator hanging point gold utensil, reduce workload, shorten the activity duration.The technical solution of the utility model is: be made up of lifting device and end closed fixture; Lifting device is made up of clamp, leading screw, leading screw adjusting part; A positioning convex is arranged at the clamp bottom, and a groove is arranged at top, has a through hole in the groove; Be fixed with the leading screw adjusting part on the leading screw, the groove fit on leading screw adjusting part bottom and the clamp, the adjusting nut on top is meshed with threads of lead screw, adjusting nut has spanner, pull spanner, rotatable adjusting nut, and leading screw is moved up and down in the leading screw adjusting part vertically; Leading screw passes the through hole on the clamp; Closed fixture two ends, end are separately fixed at the leading screw lower end of two lifting devices by bolt; But closed fixture middle part in end is the pincerlike arm of a folding, and the opening and closing place has a hole clipping, and diameter is identical with synthetic insulator upper end Metallic rod diameter, and pincerlike arm is by the bolt locking.
During construction, at first the fixed lobe of clamp bottom is placed the angle steel slit of the same shape of iron tower cross-arm, then leading screw is penetrated the through hole on the clamp, and leading screw adjusting part bottom is placed in the groove on clamp top.Synthetic insulator upper end Metallic rod is put into the hole clipping of end closed fixture, the convex annular table top of the bowl head below of end closed fixture upper surface and synthetic insulator upper end gold utensil is adjacent to, and locking pincer arm; Pull the both sides spanner simultaneously, adjust leading screw length and the end closed fixture is connected with the leading screw lower end by bolt; Continue to pull spanner and promote leading screw, the load of synthetic insulator end hanging point gold utensil is transferred on the jig of synthetic insulator end gradually, the bulb of hanging point hardware ball-head ring is loosening in the bowl head on gold utensil top, synthetic insulator upper end, and takes out from the bowl cephalic region, changes operation.
