Description
Technical field
The utility model relates to a kind of Repair of Transformer instrument, relates in particular a kind of oil immersed type oil-filled transformer sleeve pipe oil impregnate special tool for examination and repair.
Background technology
After oil-filled transformer long-time running, overload or short trouble, there is the defects such as sleeve pipe nut and conducting rod adhesion, conducting rod silk mouth and oil sealing cushion rubber burn out, thereby cause that the breakage of sleeve pipe porcelain vase, loosened screw landing, oil sealing cushion rubber cross cause thermal damage, cause Leakage in Transformer.Under traditional mode, change in the conventional instrument of cushion rubber use, when getting nut, conducting rod can rotate together along with nut, conducting rod cannot be fixed, thereby have to adopt the way of suspended core, employ forklift or crane, repair time is long, manpower and materials consumption is large, and potential safety hazard increase, is unfavorable for carrying out smoothly of site operation.
Utility model content
The utility model has overcome the deficiencies in the prior art, and a kind of oil-filled transformer sleeve pipe oil impregnate special tool for examination and repair is provided, and while having solved bushing shell for transformer oil impregnate maintenance in the past, cost is high, consumption is large and overhaul complicated problem.
For solving above-mentioned technical problem, the utility model is by the following technical solutions: oil-filled transformer sleeve pipe oil impregnate special tool for examination and repair, comprise sleeve, clamp, fixture block and clamping bar, and clamp comprise clamp, in clamp, be provided with cavity, described clamping bar is fixed on fixture block in cavity through clamp.This programme is when application, cavity is passed to conducting rod, in cavity, put into fixture block, and by clamping bar, promote fixture block conducting rod is clamped, can prevent that conducting rod from rotating, after conducting rod clamping, screw tap will be sandwiched in sleeve, thereby can, to conducting rod tapping, recover conducting rod silking, to solve the problem of loosened screw landing; Due to sleeve pipe nut and conducting rod adhesion, conducting rod can prevent that conducting rod is with cap rotation when clamping is become flexible nut afterwards, is convenient for changing oil sealing cushion rubber and damaged sleeve pipe porcelain vase; This programme is simple in structure, and size is little, carries, easy to operate, can effectively improve bushing shell for transformer oil impregnate overhaul efficiency, avoid taking because of sleeve pipe seepage the mode of suspended core processing, reduce the input of human and material resources and financial resources, reduced Field Force's labour intensity, practical.
Further, described fixture block is provided with the shrinkage pool that can stretch into clamping bar.Because fixture block is to promote conducting rod to clamp by clamping bar, so in order to prevent that fixture block from sliding after clamping, shrinkage pool is established in the place contacting with clamping bar at fixture block, and clamping bar front end stretches into shrinkage pool, in the process that clamping bar promotes, can effectively prevent that clamping bar and fixture block from sliding mutually; Shrinkage pool in this programme can be also groove, screwed hole, but considers structure and effect, and shrinkage pool is best, so this programme is selected shrinkage pool structure.
Further, described fixture block is parallel in two vertical planes of clamping bar and is provided with tongue, and described cavity is provided with the groove matching with tongue in the side corresponding with tongue, forms the bascule that fixture block slides along groove in cavity.Because fixture block is when clamping conducting rod, in order to keep fixture block steady, prevent that fixture block from rotating with conducting rod, simultaneously for easy to carry, so the mechanism by fixture block and clamp by sliding tray couples together, fixture block just can only slide and can not rotate in sliding tray like this, has improved clamping intensity.
Further, described sleeve comprises loop bar and the scroll chuck being connected with loop bar one end, scroll chuck is provided with three claws, and described scroll chuck periphery is also provided with the adjustment screw can control card pawl moving radially at scroll chuck, and the clamping face of described claw is provided with screw thread.In order to make sleeve to carry out tapping to the conducting rod screw mandrel of different size; so barrel forward end and screw tap are adopted to scroll chuck clamping; can arbitrarily adjust clamping size; at the clamping face of claw, establish screw thread and not only can increase clamping intensity simultaneously; prevent claw and screw mandrel relative sliding, the screw thread of protection screw mandrel that can also be fabulous.
Further, described loop bar is hollow rod body.Because the screw mandrel length of conducting rod is longer, in order to facilitate tapping, so loop bar is hollow rod body, the part of screw mandrel tapping can be stretched out by loop bar, can not affect tapping, practical.
Further, described loop bar is provided with through hole on the periphery away from scroll chuck one end.During due to tapping, need to use larger power, hold loop bar and can not well exert all one's strength during tapping sometimes, so can insert straight-bar in through hole, by pulling straight-bar, rotate loop bar tapping, the tapping difficulty and the physical demands that reduce a staff, improve tapping efficiency.
Further, described clamp are connected with at clamp lateral surface the bar of shaking hands, and described clamp is provided with through hole in the side relative with the bar of shaking hands, and described clamping bar is fixed fixture block through through hole.Clamp is after clamping conducting rod, thereby the hand-holdable bar of shaking hands of staff keeps clamp to maintain static, and by through hole, can well locate, and prevents that clamping bar from sliding.
Further, the side that described clamp is positioned at cavity bar one side of shaking hands is provided with arc-shaped slot I, and the side that described fixture block is corresponding with arc-shaped slot is provided with arc-shaped slot II, and arc-shaped slot II and arc-shaped slot I are equipped with screw thread.In order to strengthen clamping the screw mandrel tooth line of effect and protection conducting rod, so draw-in groove is set in the place of clamp and fixture block clamping conducting rod, and establish screw thread mate with conducting rod screw mandrel, can well protect the tooth line of conducting rod and clamp effectively, clamp firm.
Further, described through hole is provided with screw thread, and described clamping bar is provided with the screw rod mating with through hole whorl, and screw rod is connected with screw rod and shakes hands.Clamping bar needs afterburning setting fixture block can be located after clamping fixture block, in order to reduce use difficulty, so establish screw thread at through hole, clamping bar is established the screw rod mating with through hole whorl, screw rod connecting screw rod is shaken hands, and like this, staff is when needs clamp fixture block, only need hold the screw rod rotation of shaking hands, by through hole whorl, coordinate fixture block is screwed with screw rod, after screwing, by screw thread, screw rod can be locked simultaneously, without continuing to add external force, simple in structure, easy to operate; Annular knurl can be established for increasing the frictional force of shaking hands with hand, the consumption reducing a staff in screw rod in this programme surface of shaking hands.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model is simple in structure, and size is little, easy to operate, is easy to carry.
2, the utility model cost is low, can repeatedly use, effective.
3, the utility model effectively improves bushing shell for transformer oil impregnate overhaul efficiency, has simplified bushing shell for transformer oil impregnate maintenance step, practical.
