Description
Technical field
The invention belongs to clamping device field, and in particular to a kind of GIS bayonet joints Special clamping instrument.
Background technology
At present, GIS device is the important equipment of primary system in substation, and with the increase of GIS device quantity, GIS is set
Standby chamber inflated, vacuumize work with live detection it is also more and more.After primary system putting equipment in service, to ensure that substation bears
Lotus continuation is supplied, and does not arrange interruption maintenance generally, so the work of GIS device live detection has become normalization.
Work in operation field on GIS device live detection, there are problems with：
1st, GIS device connector and test splice disconnect that frequency is very high, and workload is very big, original GIS device connector
Clamping of the clamping device to GIS device connector and test splice compresses the phenomenon there are pressure imbalance, produces GIS device connector
The problem of being blocked with test splice in clamping process and causing joint gas leakage, and presence causes thimble because of pressure imbalance
Deflection is so as to the possibility of gas leakage.
2nd, many GIS device connectors are located at eminence, it is necessary to up and down respectively with one original when eminence clamps GIS device connector
GIS device connector clamping device firmly open-top connector thimble at the same time, it is necessary to two people make a concerted effort aloft operation, in operation difficulty compared with
Greatly, operating efficiency is low, and requirement of the high-rise working to personnel and instrument is high, and there are unbalanced danger, has certain safe hidden
Suffer from.
3rd, test splice is caused to be washed open after original GIS device connector clamping device there are clamping device in use, slip
Situation about dropping, aloft use when clamping device slip easily lead to eminence pendant thing hurt sb.'s feelings.
The content of the invention
The technical problems to be solved by the invention are just to provide a kind of efficient GIS bayonet joint Special clampings of clamping
Instrument.
In order to solve the above technical problems, the present invention adopts the following technical scheme that：A kind of GIS bayonet joints Special clamping work
Tool, including clamp assemblies and the latch assembly that is connected with clamp assemblies, latch assembly include fixed handle, are fixed on fixed handle

Further, the width of positioning protrusion is less than the width of the end of the first grip block, two positioning protrusion and first
Locating slot is formed between grip block.
Further, finite place piece is set on fixed pliers head, locating part include the fixed part being fixed on fixed pliers head and
It is vertical with fixed pliers head towards the limiting section of the first side extension of adjustable clamp, limiting section.
Further, the second grip block includes the connecting portion and two folders being connected on connecting portion being connected with movable binding clip
Portion is held, the middle part of two clamping parts is raised towards the first grip block.
Further, elastic component is connected between movable binding clip and fixed handle, movable binding clip is hinged with flexible handle, living
Supporting rod is connected between fixed handle and fixed handle, gag lever post is hinged with flexible handle, the end set of fixed handle has
Limit the adjusting screw of supporting rod movement.
Further, supporting rod is provided with lock projection towards gag lever post side.
Further, elastic component is spring.
Compared with prior art, the beneficial effects of the invention are as follows：
Operating procedure is as follows when the 1st, detecting：
(1) check whether each component of this Special clamping instrument is normal, particularly movable part there must not be damage to depart from；(2)
Three bolts of GIS device tip side are backed out, remove cap；(3) Special clamping instrument is lifted so that the end position of test splice
In in the U-typed bayonet of the second grip block；(4) Special clamping instrument and test splice are together directed at GIS device connector so that
GIS device connector is caught in the U-typed bayonet of the first grip block, and test splice is aligned with GIS device connector at this time；(5) press from both sides
Tight flexible handle and fixed handle, connect gas circuit, carry out the work such as this gas chamber test, detection；(6) this gas chamber detection work is complete
Finish, separate flexible handle and fixed handle, remove Special clamping instrument and test splice；When Special clamping tool holder
When test splice and GIS device connector, the first grip block and the second grip block of U-typed prevent test splice and GIS device from connecing
Head is moved in the horizontal direction, and simultaneously clamping on power prevents test splice and GIS device connector in the vertical direction from moving
Dynamic, positioning protrusion offsets with GIS device connector, prevents Special clamping instrument from coming off so that and the clamping of Special clamping instrument is firm,
More fast stablize so that GIS device connector and test splice disconnect work, improve the efficiency and security for disconnecting work.
2nd, when GIS device connector is caught in the U-typed bayonet of the first grip block, the end of GIS device connector is stuck in positioning
In the groove that raised and the first grip block is formed, fitting is even closer, and clamping is more firm, while positioning protrusion can prevent specially
Come off with clamping device, improve the safety coefficient of specific purpose tool.
3rd, clamping part of second grip block by middle part towards the first grip block protrusion so that clamping part is to have certain radian
Harden structure so that the chucking power of the second grip block and clamping direction are more stablized, and realize test splice and GIS device connector
Dichotomous balance pressurization clamping, bending projection portion can guarantee that poor with small size in test splice and GIS device connector
Different time, without adjusting adjusting screw so that the chucking power of Special clamping instrument is convenient and efficient.
4th, elastic component is connected between movable binding clip and fixed handle, movable binding clip is hinged with flexible handle, flexible handle
Supporting rod is connected between fixed handle, supporting rod make it that locking is more laborsaving, while gag lever post hinged in flexible handle
So that the locking for releasing supporting rod is more laborsaving.
5th, supporting rod is provided with lock projection towards gag lever post side, and lock projection causes supporting rod in locking flexible handle
During with fixed handle, locking effect is more preferable.
Compared with prior art, the present invention by the first grip block of U-typed and the second grip block prevent test splice and
GIS device connector is moved in the horizontal direction, while locating part and clamping force prevent test splice and GIS device connector from existing
It is moved on vertical direction, positioning protrusion offsets with GIS device connector, prevents Special clamping instrument from coming off so that exclusive clamps
The clamping for holding instrument is firm so that GIS device connector and test splice disconnect work and more fast stablize, and raising disconnects work
Efficiency and security.
