Specific embodiment
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings and examples, how to apply to the present invention whereby
Technological means solves technical problem, and the realization process for reaching technical effect can fully understand and implement.It needs to illustrate
As long as not constituting conflict, each feature in each embodiment and each embodiment in the present invention can be combined with each other,
It is within the scope of the present invention to be formed by technical solution.
Referring to Fig. 9, insulator 12 has the place that conducting wire 11 can be set up at three, and a general insulator only sets up one and leads
Line by the conducting wire 11 on insulator 12 or is pushed away when the failure of insulator 12 is needed replacing using the device of present embodiment
Or 12 original position of removal insulator drawn, it is set up again again after replacing insulator.
Referring to Fig. 1, conducting wire 11 is located at the left side of insulator 12, disengaging original position is pulled it using the present apparatus, if conducting wire
11 are located at the right side of insulator 12, are pushed out being detached from original position using the present apparatus.
It adjusts 9 height of conducting wire push-and-pull portion using lifting unit 10 to be adapted with target, lifting unit 10 can be manually rotated using spanner
Lifting.Trapezoidal screw 5 is enabled to rotate with manual operation lead screw spanner 4, trapezoidal nut 6 occurs simultaneously with trapezoidal screw 5 and insulating bar 7
Relative rotation, under the intermediation of trapezoidal nut 6, insulating bar 7 is flexible and conducting wire push-and-pull portion 9 is driven to aim at conducting wire to be operated
At 11, the state in the portion of conducting wire push-and-pull at this time 9 is as shown in figure 4, locking bar 9-3 is flicked clockwise under the action of fixing end circles round spring
U-shaped opening end is opened, conducting wire 11 is aimed at fall into U-shaped structure inside after, locking bar 9-3 is depressed with compression bar, locking bar 9-3 from
From holding the inclined-plane along inclined-plane notch contact 9-1-4 to U-shaped internal slide, pressure also enables inclined-plane notch contact 9-1-4 compressed spring
9-1-3 is shunk, and inclined-plane notch contact 9-1-4 is moved into through-hole, continued after locking bar 9-3 crosses inclined-plane notch contact 9-1-4
Downwards, until the groove of locking bar 9-3, which is fastened on fixed part 9-4, terminates compression bar movement, locking bar 9-3 is in rotating force after unclamping compression bar
The lower rotation upwards clockwise of effect, but compressed spring 9-1-3 has discharged at this time, pushes inclined-plane notch contact 9-1-4 again
It protrudes into inside U-shaped structure, the free end of locking bar 9-3 is against the indentation, there locking of inclined-plane notch contact 9-1-4,11 quilt of conducting wire upwards
It is locked in inside U-shaped structure, will not run away in push-and-pull operation process.When to 11 push operation of conducting wire, insulating bar 7 is in trapezoidal screw
5 power dominates lower elongation；When to 11 pulling process of conducting wire, insulating bar 7 shortens in the case where the power of trapezoidal screw 5 dominates.
In the bottom end insertion duplex bearing pedestal 3 of trapezoidal screw 5, there are two bearings for tool inside duplex bearing pedestal 3, are respectively cooperating with
Push and pull two kinds of operations.Twin shaft makes the light victory that becomes faster of heap position lead screw operation at pedestal.
After insulator 12 is replaced, conducting wire 11 is set up into back original position again, at this point, pulling with hand pull ring 9-1-1, then
Lock pin 9-1 integrally deviates from from through-hole, and the opening of U-shaped structure is opened, and conducting wire 11 unlocks state, then by this embodiment party
Formula device is withdrawn from conducting wire.
When reusing present embodiment device, lock pin 9-1 original road need to be only inserted into.
The inside of the insulating bar 7 of present embodiment has long cavity, screws in chamber 7-1 and lead screw telescopic cavity for the nut of connection
7-2, the diameter that nut screws in chamber 7-1 is greater than lead screw telescopic cavity 7-2, and nut screws in chamber 7-1 with internal screw thread, and lead screw is flexible
Chamber 7-2 does not have internal screw thread, does not have rotatable engagement relationship with trapezoidal screw 5, only provides space for the screw-in back-out of trapezoidal screw 5.
Nut, which screws in, is arranged trapezoidal nut 6 in chamber 7-1, trapezoidal screw 5 rotates under the action of lead screw spanner 4, trapezoidal spiral shell
Mother 6 transmits power, and trapezoidal nut 6 is threadedly coupled with insulating bar 7, then insulating bar 7 stretches but do not rotate, and can preferably allow conducting wire
Push-and-pull portion 9 is directed at conducting wire 11.
The top of insulating bar 7 clamps end chucking appliance 8, and end chucking appliance 8 divides two layers, and internal layer is that two semicircle make-ups form, right
The cylindrical body being fastened as has external screw thread, and interior receipts boss 8-1-1 is fastened in annular groove 7-3, is used for defined position, and make-up is formed
Cavity in have the side discs in construction section 7-4 and conducting wire push-and-pull portion 9, intermediate disc is worn from the gap that in-flanges is formed
It crosses.Then, outer layer retainer plate 8-2 enters from 7 bottom end side of insulating bar, and rotates on internal layer retainer ring 8-1, outer layer retainer plate 8-2
Interior receiving end 8-2-1 be fastened on it is interior receive boss 8-1-1 outside, the two shape matching.
Two are rotatablely connected between side discs and intermediate disc, and side discs and construction section 7-4 are stuck in same cavity, when
When the intracorporal side discs of chamber follow insulating bar 7 to rotate, conducting wire push-and-pull portion 9 can not rotate, and do not influence it and capture conducting wire operation.
Although disclosed herein embodiment it is as above, the content is only to facilitate understanding the present invention and adopting
Embodiment is not intended to limit the invention.Any those skilled in the art to which this invention pertains are not departing from this
Under the premise of the disclosed spirit and scope of invention, any modification and change can be made in the implementing form and in details,
But scope of patent protection of the invention, still should be subject to the scope of the claims as defined in the appended claims.
