Description
Technical field
The invention belongs to oneself under field of electrical equipment, more particularly to a kind of non-natural movement locus for insulator chain
Locking device.
Background technology
With the development and the progress in epoch of society, electricity is widely used in our life as the basic energy
In, the system transmitted electric power of China is also more and more perfect, but also there are many safety problems on overhead transmission line and do not have
There is improvement, its failure for insulating sub-connecting device is a big potential safety hazard of power network safety operation.
Used composite insulator bleed off it is in tandem be set to " R " type or " W " type locking pin, if its failure or come off, it will
The serious consequence of the disconnected connection of insulator chain is caused, the disconnected connection of insulator chain will cause immeasurable damage to the operation of whole circuit
Lose.In the inspection and tour work of circuit, often hear and sell the destroyed situation that vacancy is sold with " W " on insulator chain " W ".
The suspension insulator of the defect not only straight line pole of this " W " pin has, and the strain insulator string of anchor support also has, problem
In the presence of than wide.Reason is that, when lifting by crane insulator chain, the insulator chain weight above sling easily causes exhausted at sling
Edge bulbec rod bending or locking pin are flattened；Furthermore after circuit puts into operation, when insulator chain is waved through strong wind, it will also result in locking pin quilt
Flatten or come off.
The precautionary measures usually are：1st, increase the tour dynamics of circuit, particularly to Feng Qu, it is high across etc. special sector formulate
Rational detailed spy's plan of patrolling；2nd, during making an inspection tour, the inspection to connecting portion should be strengthened；3rd, construction is noted in work progress
Method；4th, increase to training of patrol officer etc..But, above measure can not fundamentally solve insulator locking pin deformation and
Come off.Need a kind of new locking pin to solve root problem, and then prevent the disconnected connection of insulator chain, it is ensured that the safety of supply line
Operation.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of locking effect is good, difficult for drop-off, installation side
Just the self-locking device under non-natural movement locus.
Technical scheme is as follows：A kind of self-locking device under non-natural movement locus for insulator chain,
Including bulb component and bowl head assembly, described bulb component includes bulb and ball rod, and the diameter of bulb is more than ball rod
Diameter, described bowl head assembly is the hollow columnar structures closed up and down, and a side lower part of bowl head assembly is provided with bulb and entered
Entrance, and the top of bowl head assembly is provided with the translation groove moved for ball rod, the width of rebate of the translation groove is less than bulb
Diameter, the center of the inside bottom surface of the bowl head assembly is provided with limited post, the limited post and bulb inlet port
Couple positioned opposite limited location groove.Bulb enters bowl head at bulb inlet port, and wherein bulb enters mouth structure and bulb profile knot
Structure matches, and on the one hand the setting of limited post can limit the left and right horizontal movement of bulb, make it can only after bowl head is had just enter into
Left and right translational motion is carried out between bulb inwall and the stopper slot of limited post；On the other hand it can be positioned in bulb in bulb
When in groove, limit it and move up and down the free degree, when whole insulator chain is by upward thrust, limited post can stop bulb
Depart from bulb locating slot.
Preferably, another side lower part of the bowl head assembly is symmetrically arranged with bulb inlet port.Bulb inlet port is set
Be set to it is multiple, by the stopper slot on column be set to quantity corresponding with bulb inlet port, will translation notch be set to and bulb
The corresponding quantity of inlet port, inboard wall groove is also configured as to the quantity corresponding with bulb inlet port, this programme can be provided more
Many bulb approach axis, are that approach axis is no longer single, can to a certain extent solve to change, install asking for inconvenience
Topic.
Preferably, being provided with inboard wall groove on the top bowl head assembly madial wall of the bulb inlet port, described is interior
The notch of wall groove is set towards limited post.Inboard wall groove is that bulb enters bowl head assembly providing space inside, enables bulb
Smoothly enter inside bowl head assembly.
Preferably, the height of the limited post is higher than the height of inboard wall groove bottom surface.Because limited post is highly higher than
The bottom surface of inboard wall groove, thus bulb not on lift power when its left and right horizontal movement the free degree can only be limited in
Between wall groove and limited post, the movement locus of bulb is further limit,
Preferably, the inwall upper end center position of described bowl head assembly is provided with the bulb locating slot matched with bulb.Ball
Head locating slot matches setting with bulb, and bulb positioning can be made more to consolidate.
Preferably, described bulb inlet port coordinates with bulb gap, and the gap of bulb and bulb inlet port does not surpass
Cross 8mm.And when bulb enters bulb inlet port between the two away from no more than 8mm, less clipping room away from proportionately making installing afterwards
Bulb is more difficult to deviate from from bulb inlet port.
Preferably, the minimum lateral of the inboard wall groove and stopper slot is smaller than the diameter of bulb.So set anti-
Only bulb is slid to limited post in its natural state, further limit the activity space of bulb.
Preferably, the bottom of the bowl head assembly is coaxially arranged with a bowl head rod.Bowl head rod is to be filled for convenience with other
Put and be connected.
Beneficial effect produced by the present invention：The present apparatus revolutionizes the insulator chain connected mode of existing industry, category
In a kind of brand-new attachment means and connection method, realize that the non-natural linear track of bulb is installed, under its stress very
The problem of bulb disengaging occurs in difficulty, eliminates used " R " type or " W " type locking pin.The whole movable route of bulb has a left side to have
It is right, have on have under, path is in picturesque disorder, in simple natural force when using out of doors（Along the axial pulling force of bowl head rod and vertically
The shearing force in direction）Bulb difficult to realize departs under effect, therefore ensure that the normal work of insulator chain well.
