Description
Technical field
The present invention relates to a kind of universal fixtures for substation's SF6 equipment, belong to repair apparatus technical field.
Background technique
With the development of technology, substation creates, mostly replaces traditional open type to set using GIS device in technology innovation project
Standby, GIS device is because its occupied space is few, operational reliability is high, and maintenance workload is small, the time between overhauls(TBO) is long, not by external environment item
The influence of part, adaptable feature are widely used；And traditional breaker is mostly SF6 breaker, therefore SF6 equipment is becoming
Use is extremely wide in electric equipment, therefore the micro- water test of such as SF6 of the work in SF6 equipment, inflation and maintenance etc. gradually increase,
So improving the gas collecting efficiency of SF6 equipment has very important meaning.But it yet there are no surveyed for the micro- water of SF6 both at home and abroad at present
The special mould clamp of examination, inflation and service work.Since the internal pressure equipped with SF6 equipment is larger, detection mouth is equipped with to compress
The non-return valve of formula flanged joint.The valve is different in equipment installation form, size, and staff is carrying out the work such as testing
Installation collection air valve becomes abnormal difficult when making, and needs 2-3 people to cooperate and completes, careless slightly just to will pop up, and causes to staff
Injury, breaks interface and scraps.This operating method large labor intensity, working efficiency is low, seriously threatens the person and equipment peace
Entirely, and the interruption maintenance time is extended, the safe and stable operation of substation is influenced to a certain extent, from standardized work
It differs greatly.
Summary of the invention
The present invention is to solve above-mentioned deficiency, provides a kind of self-locking SF6 valve body universal fixture, the specific scheme is that
A kind of self-locking SF6 valve body universal fixture, including the dynamic claw being oppositely arranged and determines claw, the dynamic claw and determines claw
Front end be equipped with U-shaped card slot, the width direction of U-shaped card slot and dynamic claw and to determine the distribution arrangement of claw vertical；Determine claw and
The middle part of dynamic claw is equipped with yoke plate, and one end of yoke plate is fixedly connected with claw is determined, and the other end and dynamic claw pass through the first articulated shaft
Hingedly；The tail portion for determining claw is hinged with eccentric block by the second articulated shaft, and the tail portion of dynamic claw is hinged with by third articulated shaft
Connecting rod, connecting rod are hinged by the 4th articulated shaft with the eccentric block；First articulated shaft, the second articulated shaft, third articulated shaft and
Four articulated shafts are parallel with the width direction of U-shaped card slot；The eccentric block is fixedly connected with handle.
Further, the both ends of the connecting rod are threaded with coupling head, and reverse thread connects each other for the coupling head at both ends
It connects, coupling head and dynamic claw or eccentric block are hinged.
Further, runner is fixed in the middle part of the connecting rod.
Further, the connecting rod and the hinged one end of eccentric block and determine claw tail portion and pass through circular arc face contact mutually.
Further, the positioning claw tail portion is equipped with locking slot along the inside of arc surface.
The beneficial effects of the invention are as follows easy and convenient handling to collect air valve, can reduce labor intensity, avoid personal injury, saves
Human resources, improve the flexibility of personnel assignment, to improve working efficiency, shorten the operating time.Meanwhile inventive structure letter
It is single, handle is carried, without carrying other tools such as spanner when work.
Detailed description of the invention
Fig. 1 is the main view of tooling in the present invention；
Fig. 2 is the right view of tooling in the present invention；
Fig. 3 is the left view of tooling in the present invention；
Fig. 4 is the structural schematic diagram that claw is moved in the present invention.
Specific embodiment
A kind of self-locking SF6 valve body universal fixture as shown in Figs 1-4 including the dynamic claw 1 being oppositely arranged and determines claw
2, the dynamic claw 1 and the front end for determining claw 2 are equipped with U-shaped card slot 3, the width direction of U-shaped card slot and dynamic claw and determine claw
Distribution arrangement it is vertical；The middle part for determining claw and dynamic claw is equipped with yoke plate 4, and one end of yoke plate is fixedly connected with claw 2 is determined, another
End is hinged by the first articulated shaft 5 with dynamic claw；The tail portion for determining claw is hinged with eccentric block 7 by the second articulated shaft 6, moves claw
Tail portion connecting rod 9 is hinged with by third articulated shaft 8, connecting rod and the eccentric block are hinged by the 4th articulated shaft 10；First hinge
Spindle 5, the second articulated shaft 6, third articulated shaft 8 and the 4th articulated shaft 10 are parallel with the width direction of U-shaped card slot；The bias
Block 7 is fixedly connected with handle 11.
The both ends of the connecting rod are threaded with coupling head 12, and reverse thread connects each other for the coupling head 12 at both ends, connection
Connector and dynamic claw or eccentric block are hinged.In this way, the entire length of connecting rod and coupling head can be adjusted in pivot link,
And dynamic claw can be adjusted with this and determines the compression gap between claw.
On the basis of above-mentioned connecting rod is connect with coupling head using reverse thread, runner is fixed in the middle part of the connecting rod
13, runner is conducive to the entire length of adjustment connecting rod and coupling head.
The connecting rod and the hinged one end of eccentric block and determines claw tail portion and pass through circular arc face contact mutually.Matched by arc surface
It closes and can guarantee connecting rod, eccentric block relative to determining claw slow-roll stabilization.
The positioning claw tail portion is equipped with locking slot 14 along the inside of arc surface, and the position of locking slot and dynamic claw reach pressure
Indexing when chalaza is corresponding, can automatically lock after compaction.
Pressure passes through handle, eccentric block, connecting rod etc. and is transferred to dynamic claw using lever principle, drives dynamic claw reciprocal
It is mobile.Yoke plate can guarantee dynamic claw and determine to move steadily between claw, and guarantee linking intensity and good rigidity.Screw thread connects
The telescopic connecting rod adjustable moving claw that connects and determine the final compression gap between claw, makes to collect air valve and respective flange side surface
It fits closely.The setting of radian on eccentric block, it is ensured that after reaching pressing vertex, slightly exert oneself, it is achievable voluntarily to lock function
Energy.
