Abstract
The utility model discloses a hydraulic multifunctional tensioner which settles the following problems in the prior double-hook tensioner: limited telescoping range, and high labor intensity of an operator. The hydraulic multifunctional tensioner comprises a decompression valve (2) and a manual hydraulic rod (3) which are respectively arranged on the cylinder body of a hydraulic lead screw (1). A hydraulic lead screw rod (8) which extends out from the left end is arranged in the cylinder body of the hydraulic lead screw (1). The right-end side surface of the cylinder body of the hydraulic lead screw rod (1) is provided with a connecting pin (4) fixedly and a rotatable square left bracket (5). A right closing column of the rotatable square left bracket (5) is connected with a right ring type chain (6) and a right wire tensioning hook (7). The head (9) of the hydraulic lead screw rod (8) is sleeved in a rotatable square right bracket (10). A left closing column of the rotatable square right bracket (10) is connected with a left ring type chain (11) and a left wire tensioning hook (12). The hydraulic multifunctional tensioner has the following advantages: small weight, high convenience in carrying, and simple operation.
Description
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.
