Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
It please refers to shown in Fig. 1-3, a kind of link connection combined type UHV Long Insulator String cross-arm side live-line replacing work
Tool, including screw rod, the screw rod include screw rod screw rod 1 and ratchet spanner 2, the ratchet spanner 2 is mounted on the screw rod screw rod
On 11, and abrasionproof washer 3 and parallels 4 are installed on the screw rod screw rod 1, and the abrasionproof washer 3 is located at the ratchet spanner 2
Between parallels 4；The bottom of the screw rod screw rod 1 passes through 5 connecting ball head link 7 of link screw rod, and the one of the link screw rod 5
End is connected by link nut 6；The ball-eye 7 bottom connection insulating bar 8 on bowl head 9, and the bowl head 9 with it is described
It is fixed by W pin 10 between ball-eye 7.
As a kind of optimisation technique scheme of the invention: the ratchet spanner 2 be equipped with adjust spanner up rotate or
The knob being rotated down.
As a kind of optimisation technique scheme of the invention: the lower section of the parallels 4 is set there are two groove, and the length of groove
Wide, depth is consistent with the shape of tower material right above shaft tower insulator chain.
As a kind of optimisation technique scheme of the invention: bottom use " Y " formula structure of the screw rod screw rod 1, two
There is screw hole on " Y " arm.
As a kind of optimisation technique scheme of the invention: the company of sliding between the screw rod screw rod 1 and the ball-eye 7
It connects.
In the use of the present invention, replacement tool is hung by screw rod, parallels, abrasionproof washer, link screw rod, link nut, bulb
Ring, insulating bar composition.Lead screw is made of screw rod screw rod, ratchet spanner etc., has a knob that can be used to adjust to pull on ratchet spanner
Hand is up to rotate or be rotated down.Screw rod screw rod passes through parallels and abrasionproof washer, and there are two groove, length below iron
Wide, depth is consistent with the shape of tower material right above shaft tower insulator chain, tower material can be embedded in groove, screw rod is allow to be fixed on tower
On material, tension can be transferred on tower material when replacing insulator.Abrasionproof washer mainly screw rod spanner and every being risen in iron it is slow
Punching effect, prevents screw rod spanner and parallels from directly contacting friction damage screw rod spanner and screw rod screw rod.The bottom of screw rod screw rod
Using " Y " formula structure, there is screw hole on two " Y " arms, for utilizing link screw rod and link nut ball joint link, bulb
Link can be moved forward and backward, for connecting with the bowl head at the top of insulating bar.Bowl header structure is used at the top of insulating bar, when ball-eye returns
It is fixed after in bowl head, then with the coupling part that W sells insertion link and bowl head, link and bowl head is not allowed to disengage.
As shown in Figure 1.After the completion of ground will replace tool assemble in the way of Fig. 2, it will be protected using insulation ropes
Tool is pulled on the tower material above insulator by ground, and parallels is stuck on tower material and fixes by operating personnel, by adjusting spine
Knob on wheel spanner is that spanner moves down, while abrasionproof washer being driven to move down, when ratchet spanner, abrasionproof washer with every
It can not continue after turning and being chimeric between iron and tower material between iron, the insulating bar on ground is hung and is raised to below replacement tool,
Ratchet spanner is adjusted again according to the length of insulating bar, and screw rod is made to have enough length to connect with insulating bar.Adjust ball-eye
It puts it into the bowl head of insulation club head, and being inserted into W pin fixation prevents ball-eye from deviating from, side of wire staff starts work
Make.Workflow step is as follows: after the completion of replacement tool assemble, protection tool being pulled to insulation by ground using insulation ropes
On the tower material of sub- top, parallels is stuck on tower material fixed by operating personnel；Operating personnel twists ratchet spanner and consolidates replacement tool
It is scheduled on tower material, hangs card ratchet spanner and guarantee that you have the length of macaque dog to connect with insulating bar, ball-eye push-in is then hung into liter
It in the bowl head of the insulating bar to come up, and is inserted into W pin and is fixed against ball-eye abjection, side of wire staff starts to work；
After side of wire operating personnel's power cut-off, staff takes out W pin above tower material, and the bowl head of ball-eye and insulating bar is taken off
Open, adjust ratchet spanner on knob, move up ratchet spanner, when have between ratchet spanner and abrasionproof washer it is enough away from
From being removed on Shi Congta material every iron, replacement tool is sent with insulating cord and is placed into ground.
It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er Qie
In the case where without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the present invention is by appended power
