The multifunctional hydraulic wire grip
Technical field
The present invention relates to a kind of wire grip, particularly a kind of use when transmission line is carried out the stringing operation two wires are moved to together stringing Work tool.
Background technology
Existing transmission line operation stringing Work tool mainly contains double-hook wire grip, chain chain block wire grip and ratchet tension force tightener etc.Cucurbit class wire grip, have distance of stretch out and draw back and do not limit, and to appraise and decide tonnage low but exist, the drawback that weight is excessive.Double-hook wire grip, have lightweight, simple operation, but have the limited and large defect of operator's labour intensity of distance of stretch out and draw back.
Summary of the invention
The invention provides a kind of multifunctional hydraulic wire grip, solved the limited and large problem of operator's labour intensity of distance of stretch out and draw back that existing double-hook wire grip exists.
The present invention solves above technical problem by the following technical programs:
A kind of multifunctional hydraulic wire grip, comprise hydraulic screw rod, be respectively arranged with pressure-reducing valve and hand-hydraulic bar on the cylinder body of hydraulic screw rod, be provided with the hydraulic screw rod bar that stretches out from left end in the cylinder body of hydraulic screw rod, cylinder body right-hand member side at hydraulic screw rod is fixedly installed connecting pin, the head of connecting pin is socketed in rotating square shape left socle, is connected with right ring type chain on the right sealing post of rotating square shape left socle, at the right-hand member of right ring type chain, is provided with right wire-tightening hook; The head of hydraulic screw rod bar is socketed in rotating square shape right support, is connected with left ring type chain on the left sealing post of rotating square shape right support, at the right-hand member of left ring type chain, is provided with left wire-tightening hook.
The right sealing post of described square shape left socle is an active pin shaft, and the left sealing post of described square shape right support is also an active pin shaft.
The characteristics of the present invention has lightweight, easy to carry and processing ease, and operation core carries unrestrictedly, and distance of stretch out and draw back can be adjusted according to the operation field actual needs, greatly reduces simultaneously operating personnel's labour intensity.

Embodiment
a kind of multifunctional hydraulic wire grip, comprise hydraulic screw rod 1, be respectively arranged with pressure-reducing valve 2 and hand-hydraulic bar 3 on the cylinder body of hydraulic screw rod 1, when with subordinate, pressing hand-hydraulic bar 3, hydraulic screw rod bar 8 will stretch out left, after depressing pressure-reducing valve 2, hydraulic screw rod bar 8 will be retracted in the cylinder body of hydraulic screw rod 1, be provided with the hydraulic screw rod bar 8 that stretches out from left end in the cylinder body of hydraulic screw rod 1, cylinder body right-hand member side at hydraulic screw rod 1 is fixedly installed connecting pin 4, the head of connecting pin 4 is socketed in rotating square shape left socle 5, be connected with right ring type chain 6 on the right sealing post of rotating square shape left socle 5, right-hand member at right ring type chain 6 is provided with right wire-tightening hook 7, by rotating freely square shape left socle 5, can reach to adapt to and be pulled the wire trend, the head 9 of hydraulic screw rod bar 8 is socketed in rotating square shape right support 10, is connected with left ring type chain 11 on the left sealing post of rotating square shape right support 10, at the right-hand member of left ring type chain 11, is provided with left wire-tightening hook 12.
The right sealing post of described square shape left socle 5 is an active pin shaft, the left sealing post of described square shape right support 10 is also a movable bearing pin, the bearing pin that disassembles the bearing pin of right sealing post and left sealing post can be realized fractionation and the combination to wire grip, carry in convenient work, in addition,, as long as change the different ring type chain of length, just can complete the stringing task of different distance of stretch out and draw backs.
