Abstract
The utility model discloses a miniature disconnection type telescopic joint for GIS/H-GIS. The disconnection type telescopic joint comprises a corrugated pipe, flanges and a plurality of pull rods. The flanges are disposed at two ends of the corrugated pipe. The pull rods are disposed outside the corrugated pipe and located between the flanges at two ends. The pull rods are evenly distributed along the periphery of the end faces of the flanges. Two ends of each pull rod are respectively connected with the flanges at two ends through bolts. By the arrangement, space limitation of peripheral equipment is avoided, the telescopic joint is convenient and flexible to mount and demount and simple in structure, and work efficiency is increased greatly. In addition, the flanges adopt the standard flange outer diameters in GIS/H-GIS, the flange diameter and thickness are reduced, the joint is small in size and lightweight, and manufacturing cost is lowered greatly.
Description
Technical field
The utility model relates to a kind of slip joint, relates in particular to a kind of GIS/H-GIS miniaturization and off-type slip joint.
Background technique
At present, the metal enclosed gas-insulated switch of GIS/H-GIS() equipment is when install at the scene, owing to inevitably there is some machining errors and alignment error, can cause GIS/H-GIS equipment that difficulty is installed and even cannot install, must pass through off-type slip joint and just can complete installation.The GIS/H-GIS equipment having moved, overhauling while disassembling, in order to reduce the scope of disassembling, is shortened and disassembled the time, also need to disassemble from off-type slip joint.
Existing GIS/H-GIS equipment is using off-type slip joint comprise two flanges and be arranged on the bellows between flange, between two flanges, be provided with cylinder lever connecting rod, one end of cylinder lever connecting rod is fixed on the first flange by locking nut, and the other end of cylinder lever connecting rod is fixed on the second flange by adjusting nut and locking nut.During use, need be by cylinder lever connecting rod along flange shaft to penetrating from the flange hole of the second flange, after being connected with the first flange, then the parts such as secured adjusted nut and locking nut, install, dismounting takes up room greatly, is subject to the restriction of surrounding space.In addition, existing GIS/H-GIS equipment is using off-type slip joint flange diameter very large, is causing that off-type slip joint volume is large, weight is large, and manufacture cost is high.
Model utility content
The purpose of this utility model is to provide a kind of GIS/H-GIS miniaturization and off-type slip joint, is not subject to the spatial constraints of surrounding devices during use, installs, disassembles flexible, also has advantages of that volume is little, lightweight, cost is low, simple in structure simultaneously.
The utility model adopts following technical proposals:
A kind of GIS/H-GIS off-type slip joint with miniaturization, comprise bellows and the flange that is arranged on bellows two ends, also comprise along two ends flange and be axially disposed within bellows outside and many pull bars between two end flange, many pull bars are circumferentially uniformly distributed along end face of flange, and the two ends of pull bar are connected with two end flange by bolt respectively.
Described pull bar two ends are provided with attachment hole, and attachment hole internal surface is provided with the internal thread matching with airtight bolt outside thread.
Described two ends flange outer diameter is identical with GIS/H-GIS Plays flange outer diameter.
The two ends of described pull bar are connected with two end flange by airtight bolt respectively.
Described two end flange and bellows-welding.
Described bellows adopts corrugated stainless steel tubing.
Between two described end flange, be provided with 8 pull bars.
The utility model is in bellows outside and many pull bars are set between two end flange, is no longer subject in use the spatial constraints of surrounding devices, installs, disassembles flexibly and easily, and structure is more simple, has greatly improved working efficiency; Further, the utility model two ends flange outer diameter adopts GIS/H-GIS Plays flange outer diameter, and flange diameter reduces, reduced thickness, has little, the lightweight advantage of volume, has significantly reduced manufacture cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is use view of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises bellows 1, is arranged on flange 2 and the pull bar 3 at bellows 1 two ends, and bellows 1 adopts corrugated stainless steel tubing, and two end flange 2 external diameters are identical with GIS/H-GIS Plays flange outer diameter and be welded on bellows 1 two ends.Bellows 1 is outside and be provided with many pull bars 3 between two end flange 2, and the two ends of pull bar 3 are provided with attachment hole, and attachment hole internal surface is provided with the internal thread matching with airtight bolt 4 outside threads.3,8 pull bars 3 of 8 pull bars are set in the present embodiment altogether and all along two end flange 2, axially arrange and be circumferentially uniformly distributed along flange 2 end faces, the two ends of pull bar 3 are connected with two end flange 2 with the airtight bolt 4 arranging in two end flange 2 by attachment hole respectively.
As shown in Figure 2, when needs are installed the utility model between adjacent two GIS equipment 5, first dismantle lower link 3, then use frock compress bellows 1, adjust execute-in-place requisite space, then carry out the connection of conductor; Finally utilizing frock that bellows 1 is resetted, by two end flange 2 respectively with two GIS equipment interconnections, and pull bar 3 is installed.By adjusting all right canceller machining error of length and the on-the-spot alignment error of pull bar 3 and bellows 1, guarantee the normal mounting of GIS equipment.
When needs are dismantled the utility model, first dismantle lower link 3, and two end flange 2 and GIS equipment are separated; Then use frock compress bellows 1, to adjust execute-in-place requisite space; Disassemble again conductor; The lower the utility model of finally dismounting.
Installing during pull bar 3, directly between two end flange 2 along flange 2 radial translation to flange hole position, the airtight bolt 4 in attachment hole and the flange hole that pull bar 3 two ends are arranged forms screw-thread fit.
When disassembling pull bar 3, first by airtight bolt 4 from pull bar 3 two ends arrange attachment hole in take out, and then by pull bar 3 between two end flange 2 along flange 2 radial translation take out.
The utility model, when installing, disassembling, is not subject to the spatial constraints of surrounding devices, installs, disassembles flexibly and easily, has greatly improved working efficiency; Meanwhile, in the utility model, two end flange 2 external diameters adopt GIS/H-GIS Plays flange outer diameter, and flange 2 diameters reduce, reduced thickness, have little, the lightweight advantage of volume, have significantly reduced manufacture cost.
