It is preferred that the angle steel fixing seat 1 includes inverted L-shaped support arm and fastening bolt 13, inverted L-shaped support arm includes cross bar 11 and erects
Bar 12, the cross bar 11 are fixedly connected with the control device ontology 26, make the inverted L-shaped support arm and control device ontology 26 it
Between form the accommodating space of angle steel, open up fixation hole on the vertical bar 12, the fastening bolt 13 is mounted on perpendicular by fixation hole
On bar 12.
As shown in figure 4, lift slide bar handle 25 manually when clamping the conducting wire 7 of big line footpath and up promoted, traction control line
Up move certain stroke.At this point, being pulled stroke adjustment block 45 and left clamping jaw 44 around the second pin shaft up time by the traction of control line
Needle swings certain angle, squeezes conducting wire, when be extruded by conducting wire push down right clamping jaw when, the first clamping part 431 of right clamping jaw by
Conducting wire is pressed the first tension spring lengthening deformation, and the first tension spring forms counter pull to the first clamping part 431, to make left clamping jaw
44 and right clamping jaw together by conductor clamping.After left clamping jaw 44 clamps conducting wire, slide bar handle 25 does not rise to be moved to and be limited at this time
The position that position is stuck in, still needs to continue to move up, and continues to pull stroke adjustment block 45 and left clamping jaw 44 while mobile, at this moment
Left clamping jaw 44 has clamped conducting wire and can not move, and stroke adjustment block 45 is towed the effect of power, starts turning around third pin shaft,
Its limiting section 453 is gradually distance from the second forced section 443 of left clamping jaw 44, is formed centainly with the second forced section 443 of left clamping jaw 44
Angle complete the conducting wire clamping of big line footpath until moving to and being limited by slide bar limiting device 24 on slide bar handle 25.
As shown in figure 5, clamp the conducting wire 7 of small line footpath as the conducting wire for clamping big line footpath, unlike the small line footpath of clamping
Conducting wire when, when conducting wire of the left clamping jaw 44 around the angle that the second pin shaft rotates clockwise than clamping big line footpath, is big.When left clamping jaw
44 and right clamping jaw together by after the conducting wire of the small line footpath of conductor clamping, the of the limiting section 453 of stroke adjustment block 45 and left clamping jaw 44
It is formed by angle between two forced sections 443 and is less than the angle for clamping the conducting wire of big line footpath.Therefore, by stroke adjustment block 45 with
Second forced section 443, which is formed by elastic corner dimension, can realize the conducting wire for clamping different line footpath sizes.Meanwhile according to practical need
It wants, by screwing position of the locking nut on ring screw 48, the deformation of support spring 46 can also be adjusted, realized to folder
The adjusting of the chucking power size of conducting wire is held, so that can guarantee to clamp securely, have when clamping the conducting wire of different-diameter
Effect avoids falling off.
After clamping conducting wire, the suitable high voltage iron tower angle steel 6 of staff's selection is caught in inverted L-shaped support arm and control device sheet
Accommodating space between body 26 compresses angle steel 6 by adjusting fastening bolt 13, this earthing or grounding means can be hung over high voltage iron tower
On.
