Description
Technical field
The present invention relates to a kind of electric power overhaul instrument, more particularly to a kind of insulator locking pin pin removal.
Background technology
In power transmission lines overhauling, the insulator locking pin that uses at present（Predominantly R types pin）Pin pulling tool mainly has always
Vice, self-control sled hook etc..The R type pins of SI semi-insulation can only be extracted with vice;Self-control sled, which hooks, firmly needs different conversion to make
With point, R pin zinc coats are easily worn, pole expends bodily strength.Furthermore two kinds of instruments are all rectilinear form, anti-pollution type insulator lock is being pulled out
During tight pin, the space for operation of not pulling pin, easily glass insulator is smashed during choosing, it is exhausted to change Defile-proof for Electric Transmitting Line type
Certain difficulty be present in edge.With self-destruction insulation quantum count it is increasing, in the case of maintainer's limited strength how
Enough the problem of more rapidly, effectively and safely changing self-destruction pollution proof insulator, have become increasingly conspicuous.Part locking pin can not be pulled out smoothly
Go out, have impact on the efficiency for changing insulator, there is an urgent need to develop a kind of new pin pulling tool.
The mode of pulling pin being commonly used at present has：R types pin, which is gone out using tiger clamp or hooked with self-control sled, is prized loosening
After extract.Problems be present in both traditional modes of pulling pin：（1）In R type pin withdrawal process, the mode of clamp can cause
The zinc coat of locking pin surface sustains damage, and anti-corrosion capability declines, and reduces its service life.（2）When choosing locking pin,
Need constantly to convert stress point position and Impact direction, elapsed time is longer, while R pins can be caused to loosen deformation；（3）Due to anti-
The dirty big shirt rim of type insulator covers locking pin completely, and both traditional instruments are easily blocked in operation by shirt rim, lack behaviour
Make space, operation by force easily causes insulator and is breached.
The content of the invention
The technical problems to be solved by the invention, which are to provide one kind, can quickly extract insulator locking pin and work strong
Spend minimum insulator and push away formula pin removal with rotation.
In order to solve the above-mentioned technical problem, the present invention adopts the following technical scheme that：
A kind of insulator pushes away formula pin removal with rotation, including lifting-hook shape is pulled pin hook, and the hook vertical section of pulling pin, which is fixed, to be connected
Vertical screw shell is connected to, thrust screw rod with matching, the vertical thread bush are connected with the vertical screw shell
The outer movable sleeve of cylinder is connected to inverted L shape support, and the inverted L shape support can axially slide up and down along vertical screw shell, the thrust spiral shell
The upper end of bar is provided with rotary handle.A kind of insulator of the present invention pushes away formula pin removal with rotation, can by rotary thrust screw rod
Make vertical screw shell drive hook of pulling pin to produce displacement straight up, while can have by the way that inverted L shape branch is placed on into locking pin side
Effect avoids pulling pin hook inclination, so as to ensure locking pin by vertically upward, being so both easy to quickly extract locking pin to withdrawal force,
Operation labor intensity is greatly reduced again.
Preferably, the inverted L shape support passes through the bracket sleeve tube being sleeved on outside vertical screw shell and vertical thread bush
Cylinder connection, coordinates between the bracket sleeve tube and vertical screw shell for gap, and inverted L shape support and perpendicular is connected by bracket sleeve tube
Straight screw sleeve, both it is easy to fabricate, is easy to ensure its relative slip up and down again.
Preferably, the outer surface of the vertical screw shell is vertically arranged with a rectangle plane, bracket sleeve tube inner surface
Also it is provided with the plane being engaged with vertical screw shell, it is described to pull pin hook and inverted L shape support is located at vertical screw shell homonymy
Same perpendicular in, be designed as plane by wherein one section by the mating surface of bracket sleeve tube and vertical screw shell, so
Inverted L shape support can be avoided to rotate to ensure its support force, the rectangle plane on vertical screw shell is easy at it again in addition
Lower end connects hook of pulling pin.
Preferably, the hook vertical section of pulling pin is welded to connect with vertical screw shell, the hook that will pull pin is welded in vertical spiral shell
On rectangle plane on line sleeve, connection is very firm.
Compared with prior art, insulator of the present invention rotates the beneficial effect for pushing away formula pin removal：Pass through thrust screw rod
With inverted L shape supporting structure, withdrawal force straight up accurately can be imposed to locking pin, easily and quickly will lock so as to realize
Tight pin is extracted from insulator bowl head.The present invention causes to pull pin narrow space and influence the R that chooses for the big shirt rim of pollution proof insulator
The problem of type locking pin, the conversion of the application point, the mode of action using power is devised, can be used outside shirt rim and rotate thrust,
Push away out R type locking pins.Formula pin removal, which is pushed away, using rotation carries out operation of pulling pin, position when successful transformation is pulled pin firmly, more
Add it is laborsaving, convenient, rapidly locking pin is extracted；Change original clamp simultaneously to pull pin mode, reduce the damage to R type pins.
