The size of fixing hole designs with spacing according to specifically wire triangle yoke plate related data.
The utility model screw mandrel includes screw set, supporting plate, bearing block;Screw is provided with bevel gear group, big on screw Bevel gear is by supporting ball bearing crank is closed with small bevel gear wheel shaft vertical junction;The screw end of bearing block, which is provided with, is oriented to ball bearing, The screw other end connects ratchet.
The utility model is bolted on the fixed plate of triangle yoke plate, retains traditional rotary screw, can be adjusted by knob Rotation direction ratchet handle is saved, the thread-lifting hook mutually agreed with ground linear diameter, thread-lifting hook top layer uses anti-skidding glue-line.Fixed plate is set to Groove body, bolt hole is provided with the wall of fixed plate two, for the connection of fixed plate fixing bolt triangle yoke plate, is installed in fixed plate After in place, the groove of thread-lifting hook will be put into by maintenance ground wire, after confirming that ground line position is accurate, the knob of ratchet is gone to and tightens up position Put, screw mandrel is tightened up by handle, so as to be lifted by maintenance ground wire, play the purpose of easy access.
The use of the utility model instrument easily occurs relative to hand chain block, cucurbit upper end fixing point position stress Skew, and the special the Line tool upper end fixing point position that carries of ground wire is more accurate, stress point will not occur partially with tightening up for screw mandrel Move, so as to reduce operating risk.The special handle for carrying the Line tool of ground wire can change the length arm of force according to actual job, mitigate operation Personnel labor intensity.Ground wire is special, and to propose the Line tool design use lighter, the aluminum alloy material of high intensity, mitigates operating personnel and takes Band burden.
The utility model is that one kind carries line specific purpose tool, is especially adapted for use in the cross, straight streamline of multiple-loop line road extra-high voltage Change overhead transmission line connection equipment tool equipment material in road.
The utility model is according to multiple-loop line road extra-high voltage AC and DC overhead transmission line pendency string mode and insulator chain Assembling figure, carry out multiple-loop line road extra-high voltage AC and DC overhead transmission line suspension string and change aerial earth wire connection equipment gold utensil Size carries out Special-purpose lifting tool design.
The utility model ground wire is special to be put forward the Line tool fixed plate and is set to groove and be directly fixed on overhead transmission line ground wire gold On tool, using former triangle yoke plate design it is remaining construction hole on installation special tool device, can with it is general, mounting process is easy, quick.
The utility model ground wire is special to put forward the Line tool beneficial effect:1) installation is simple, can after the completion of ground staff is composable It is transferred to by transmitting rope on tower, staff only needs can install the special the Line tool that carries of ground wire for 1 minute on tower;2) Ground wire is special to carry the Line tool in use, only needs single-character given name operating personnel, compared with traditional Hand operating hoist, larger shortening Line correlation upkeep operation time 30min, taken so as to reduce operating risk, mitigation operating personnel labor intensity, mitigate operating personnel Band burden;3) save the personnel amount of interruption maintenance input, improve operating efficiency, shorten power off time.
