Abstract
The utility model relates to a lifting tool for live lifting of leads of 500kV power transmission lines, and particularly relates to a lifting lead-screw for 500kV power transmission lines, which solves problems that existing lifting lead-screws and insulating lifting rods are difficult in connection, the lifting rods are easy to fall off and the like. The lifting lead-screw comprises a lead-screw, a lead-screw holder, a nut and a connecting part, wherein a mounting tube is fixed at the single end of the lead-screw, the lead-screw holder is sleeved on the lead-screw, the nut is arranged on the lead-screw and provided with a handle used for driving the nut to rotate, the connecting part is in threaded fixation with the mounting tube, the connecting part adopts a hook, and a handle of the hook is provided external thread fixed with the thread of the mounting tube. Besides, the bottom end of the handle of the hook is provided with a through hole at the hook opening, and a closed loop penetrating through the through hole and used for closing the hook opening is arranged at the through hole. The lifting device is simple in structure and convenient for use, and can avoid falling off effectively. In addition, connection between the insulating lifting rod and the lifting lead-screw can be completed by only one worker, thereby reducing amount of workers, lowering labor intensity and shortening working time.
Description
Technical field
The utility model relates to the charged lifting lead of 500kV transmission line with carrying the Line tool, specifically is that a kind of 500kV used for transmission line is carried the filament thick stick.
Background technology
The charged lifting lead of 500kV transmission line mostly uses the wire lifting hook, the thread takeup lever that insulate, carry the filament thick stick and constitute and carry the Line tool, is mainly used in whole string (monolithic) insulator of charged for replacement tangent tower and strain tower drainage string and changes operation such as ball-eye.
At present when implementing the charged lifting lead of 500kV transmission line, at first will carry the filament thick stick and be passed to cross-arm hanging point place, by operation electrician on the tower it is installed in the gap location that leans against back iron at cross-arm hanging point two ends, by the ground electrician wire lifting hook and insulation thread takeup lever assembling back transmission are gone up tower then, the electrician inserts the thread takeup lever end in the fixing U type socket in leading screw end on the tower, with thread takeup lever end installing hole with after the installing hole of leading screw end U type socket aligns, connecting bolt is penetrated and fix, could realize being connected of thread takeup lever end and leading screw end, it is bigger to connect difficulty, and labour intensity is big, and the required activity duration is longer.In addition, promote in the lead process tightening up leading screw,, the nut of fixedly connected bolt is come off, cause thread takeup lever to come off because thread takeup lever and leading screw connecting bolt can swing back and forth after stressed.
Summary of the invention
The utility model is connected problems such as difficulty is big, big, the required activity duration of labour intensity is long, easily take place that thread takeup lever comes off in order to solve the existing filament thick stick of carrying with thread takeup lever, provide a kind of 500kV used for transmission line to carry the filament thick stick.
The utility model is to adopt following technical scheme to realize: the 500kV used for transmission line is carried the filament thick stick, comprise the single-ended leading screw that is fixed with mounting pipe, be set on the leading screw and be used for the leading screw seat fixing, be arranged at nut on the leading screw, be used to be connected the connector of leading screw and the wire lifting hook or the thread takeup lever that insulate with transmission line pylon cross-arm, nut is provided with the handle that drives its rotation, and connector and mounting pipe screw thread are fixed; Described connector adopts suspension hook, and the neck of hook of suspension hook is provided with and the fixing external screw thread of mounting pipe screw thread.
Use described in the utility model carry the filament thick stick before, need the insulation thread takeup lever is transformed, promptly adopt cyclic adapting piece in insulation thread takeup lever end, like this when implementing charged lifting lead, the operation electrician only needs the cyclic adapting piece of thread takeup lever hung in the suspension hook of leading screw end and gets final product.Changing original bolt connection between thread takeup lever and the leading screw into hook-hang type connects.
Deviate from suspension hook for the cyclic adapting piece that prevents thread takeup lever, suspension hook neck of hook bottom offers the through hole that is positioned at suspension hook mouth of hook place, and the through hole is provided with the sealing ring set that passes through hole and be used to seal the suspension hook mouth of hook.Like this, after the cyclic adapting piece for the treatment of thread takeup lever is hung suspension hook, get final product with the sealing ring set sealing suspension hook mouth of hook.
The utility model is simple in structure, and is easy to use, only needs a staff to finish and insulate thread takeup lever and carry being connected of filament thick stick, saved the operating personnel, alleviated labour intensity, reduced the activity duration; And can effectively prevent the generation that thread takeup lever comes off.
