Description
Technical field
The invention belongs under field of electrical equipment more particularly to a kind of non-natural motion profile for insulator chain from
Locking device.
Background technique
With the development of society and the progress in epoch, electricity is widely used in our life as the basic energy
In, the system to transmit electric power in China is also more and more perfect, but there is also many safety problems not to have on overhead transmission line road
There is improvement, the failure of insulation sub-connecting device is a big security risk 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 fall 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 entire route
It loses.In the inspection and tour work of route, the case where insulator chain " W " pin is destroyed and " W " sells vacancy is often heard.
The suspension insulator of the defect not only straight line pole of this " W " pin has, but also the strain insulator string of anchor support also has, problem
In the presence of than wide.The reason is that the insulator chain weight above sling easily causes exhausted at sling when lifting by crane insulator chain
Edge bulbec rod bending or locking pin flatten；After furthermore route puts into operation, when insulator chain is waved through strong wind, locking pin quilt will also result in
It flattens or falls off.
The precautionary measures usually are: 1, increase the tour dynamics of route, especially to Feng Qu, it is high across etc. special sectors formulate
The reasonable detailed spy plan of patrolling；2, during making an inspection tour, the inspection to connecting portion should be reinforced；3, construction is paid attention in work progress
Method；4, the training etc. to patrol officer is increased.But the above measure cannot fundamentally solve insulator locking pin deformation and
It falls off.A kind of novel locking pin is needed to solve root problem, and then prevents the disconnected connection of insulator chain, guarantees the safety of power supply line
Operation.
Summary of the invention
A kind of it is an object of the invention to overcome the deficiencies of the prior art and provide locking effects good, not easily to fall off, installation side
Just the self-locking device under non-natural motion profile.
Technical scheme is as follows: the self-locking device under a kind of non-natural motion profile for insulator chain,
Including bulb component and bowl head assembly, the bulb component includes bulb and ball rod, and the diameter of bulb is greater than ball rod
Diameter, the bowl head assembly are the hollow columnar structures being all closed up and down, a side lower part of bowl head assembly be provided with bulb into
Entrance, and the top of bowl head assembly is provided with the translation slot mobile for ball rod, the width of rebate of the translation slot is less than bulb
Diameter, the center of the inside bottom surface of the bowl head assembly are provided with limited post, the limited post and bulb inlet port
Opposite side is provided with limiting slot.Bulb enters a bowl head from bulb inlet port, and wherein bulb enters mouth structure and bulb shape knot
Structure matches, and on the one hand left and right horizontal that the setting of limited post can limit bulb is mobile, makes it can only after having just enter into bowl head
Left and right translational motion is carried out between bulb inner wall and the limiting slot of limited post；On the other hand bulb positioning can be in bulb
It when in slot, limits it and moves up and down freedom degree, when entire insulator chain is by upward thrust, limited post can stop bulb
It is detached 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
It is set to multiple, sets quantity corresponding with bulb inlet port for the limiting slot on column, sets translation notch to and bulb
Inboard wall groove is also configured as quantity corresponding with bulb inlet port by the corresponding quantity of inlet port, and this programme is capable of providing more
More bulb approach axis is that approach axis is no longer single, can solve replacement to a certain extent, install inconvenient ask
Topic.
Preferably, being provided with inboard wall groove on the top bowl head assembly inner sidewall of the bulb inlet port, described is interior
The notch of wall groove is arranged towards limited post.Inboard wall groove is that bulb enters a bowl head assembly providing space inside, enables bulb
It can smoothly enter into inside bowl head assembly.
Preferably, the height of the limited post is higher than the height of inboard wall groove bottom surface.Since limited post height is higher than
The bottom surface of inboard wall groove, therefore when bulb upper lifting power in the mobile freedom degree of its left and right horizontal can only be limited in
Between wall groove and limited post, the motion profile of bulb is further limited,
It is positioned preferably, the inner wall upper end center position of the bowl head assembly is provided with the matched bulb of bulb
Slot.Bulb locating slot matches setting with bulb, and bulb positioning can be made more firm.
Preferably, the bulb inlet port and bulb clearance fit, 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 be no more than 8mm, lesser clipping room away from installation proportionately make afterwards
Bulb is more not easy to deviate from from bulb inlet port.
Preferably, the minimum lateral spacing of the inboard wall groove and limiting slot is less than the diameter of bulb.Setting is anti-in this way
Only bulb is slid in its natural state to limited post hereinafter, further limiting the activity space of bulb.
Preferably, the lower part of the bowl head assembly is coaxially arranged with a bowl head rod.Bowl head rod is to fill for convenience with other
It sets and is connected.
The utility model has the advantages that the present apparatus revolutionizes the insulator chain connection type of existing industry caused by of the invention, belong to
In a kind of completely new attachment device and connection method, the non-natural linear track installation of bulb is realized, under its stress very
There is the problem of bulb disengaging in difficulty, eliminates used " R " type or " W " type locking pin.The entire 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 (along the pulling force and vertically of bowl head rod axial direction when using outdoors
The shearing force in direction) bulb difficult to realize is detached under effect, therefore ensure that the normal work of insulator chain well.
