Description
Technical field
The present invention relates to GIS detecting tool apparatus fields, especially slide block type double cam SF6 valve body universal fixture.
Background technique
With the development of technology, substation creates, mostly replaces traditional open type to set using GIS device in technology innovation project
It is standby.GIS(gas-insulated metal encapsulates switchgear).GIS device because its occupied space is few, operational reliability is high, preparation is flexible,
Maintenance workload is small, the time between overhauls(TBO) is long, do not influenced by external environmental condition, adaptable feature is widely used.GIS
Breaker be mostly SF6(sulfur hexafluoride) breaker, SF6 breaker micro- water test, inflation and maintenance etc. gradually increase.
In the prior art since the SF6 gas pressure of the inside equipped with SF6 equipment is larger, detection mouth is equipped with compression type
The non-return valve of flanged joint needs to take down the valve deck of non-return valve when needing to detect or repair, then is manually aligned using collection air valve
Non-return valve carries out compressing gas collection or inflation.Non-return valve is different in equipment installation form, size, internal pressure again very
Greatly, staff, which installs collection air valve when detecting or repairing, becomes abnormal difficult, needs 2-3 people to cooperate and completes, slightly not
Careful collection air valve will pop up, and damage to staff, and collection air valve interface, which can also be broken, to be scrapped.This operating method labour is strong
Degree is big, and working efficiency is low, seriously threatens the person and equipment safety, and extend the interruption maintenance time, to a certain extent
The safe and stable operation for influencing substation, differs greatly from standardized work.This just need a kind of micro- water test of SF6 valve body,
The special tooling fixture of inflation and service work.
Summary of the invention
The invention aims to provide slide block type double cam SF6 valve body universal fixture.
In order to achieve the above objectives, the present invention is implemented according to following technical scheme:
Slide block type double cam SF6 valve body universal fixture, including determine claw, dynamic claw, claw mandrel, reset spring, two cams,
Cam mandrel, claw mandrel side are provided with claw mandrel cap, and the claw mandrel other side is provided with two-sided flat position, on two-sided flat position
It is provided with cam core axle hole；Determine claw and dynamic claw is provided with valve pool, determines claw and be additionally provided with claw core axle hole, dynamic claw is set
It is equipped with flat position hole, claw core axle hole and claw mandrel are interference fitted, flat position hole and two-sided flat position clearance fit；Pair of claw mandrel
The face side Bian Wei passes through claw core axle hole, reset spring and flat position hole；Two cams are provided with hexagonal hole；Cam mandrel is provided with
Nut, two six square shaft pins, external screw thread, nut, six square shaft pins and hexagonal hole are interference fitted, and external screw thread matches with nut, and two
A cam is fixed on the two sides of two-sided flat position by cam mandrel, and cam mandrel is hinged by cam core axle hole and claw mandrel
It connects, two cams and dynamic claw connect；Dynamic claw is fixedly installed sliding block between the top in flat position hole, two cams,
Sliding block and two cam clearances cooperate, and sliding block and claw mandrel connect.
Further, the valve pool top is provided with valve pool snap ring, U-shaped annular groove, pin, valve pool snap ring side and valve
Slot top is hinged, and is provided with pin hole in the other side of valve pool snap ring side and annular groove, pin matches with pin hole.
Further, the valve pool is U-type groove.
Further, described two cams are provided with quiet vertical plane, slip cambered surface, stop cambered surface, stop the projection of cambered surface
The diameter of circular arc is greater than the diameter of the projection circular arc of slip cambered surface.
Further, the outer profile for determining claw and dynamic claw is in Y type.
The invention has the benefit that
1. completing the connection of the non-return valve and collection air valve of SF6 with regard to fast operating by a people by using the present invention, letter is used
It is single, easy to operate, it improves work efficiency: cam mandrel band moving cam being twisted by torque spanner and is rotated, so that dynamic claw, quiet
Claw easily docks non-return valve with collection air valve, dynamic claw and determine mobile steady between claw, and guarantees linking intensity and well
Rigidity, non-return valve and collection air valve the uniform axially loaded of flange, complete SF6 gas collection, deflate；
2. dynamic claw of the invention determines the pop-up that claw prevents from collection air valve, reduce the potential person wound to operator
Evil can also prevent the damage of collection air valve；
3. the cooperation of valve pool snap ring and dynamic claw, quiet claw can further prevent the pop-up of collection air valve, increase safety coefficient,
It can also be used under the non-return valve of different flange thicknesses and the operating condition of collection air valve；
If being processed 4. determining claw and dynamic claw using thicker steel plate, although dynamic claw and the sliding of claw mandrel are lighter,
Increase the weight of device and use difficulty, the design for determining claw and dynamic claw of Y type is so that weight saving, (reduction easy to use
The length of cam mandrel；It is twisted using spanner more convenient)；
5. the design limitation of the sliding block freedom degree of dynamic claw, anti-stop claw generates angle offset when claw mandrel slides,
Dynamic claw will not bite, stuck when resetting；
6. structure of the invention is simple, components are few, easy to process, and the precision for needing to cooperate is low, easy to spread.
