Description

Change the specific purpose tool of two divisural line conductor spacers
Technical field
The utility model relates to a kind of electrician's instrument using while keeping in repair transmission line, is specially a kind of specific purpose tool for restringing conductor spacer.
Background technology
The conductor wire of ultra-high-tension power transmission line is often used double bundle conductor, and double bundle conductor is generally to have the sub-conductor that two horizontal parallel are arranged to form, and the distance between two root wires of double bundle conductor is generally 0.4m.On double bundle conductor, need to separate sub-conductor by lead spacer, twisted together to prevent sub-conductor.Due to wire vibrations or the fastening factor impact such as not in place of rotating shaft, lead spacer there will be loosening or damages, and as repair and replacement not in time, conductor spacer long term wear wire will cause broken string, the major accident such as bar.During charged for replacement conductor spacer, employing be soft ladder busywork method.Rope ladder is suspended on a root wire, and when operating personnel arrives installation site by climbing rope ladder, once open conductor spacer, the weight that personnel self add rope ladder will make to pull open up and down certain distance between sub-conductor and another root wire.If two root wires can not be retracted and remain on the distance of 0.4 meter, operating personnel just cannot change, install new conductor spacer.Instrument for restringing conductor spacer is substantially all comprised of insulating bar and retractor device two parts at present, the specific purpose tool of replacing bundle conductor conductor spacer as disclosed in Chinese patent literature ZL201210308768.6, it is mainly comprised of insulating bar and retractor device, insulating bar and retractor device connect as one, the upper end of retractor device is provided with insulating hanger, the lower end of retractor device is provided with insulation drag hook, link up with identical with drag hook orientation, distance between retractor device extended state lower draw-bar and drag hook is greater than the spacing of bundle conductor, distance between retractor device retraction lower draw-bar and drag hook equals the spacing of bundle conductor.Its retractor device is screw telescopic device, the drawback of this retractor device is complex structure, during operating cost, and need bimanualness, be unfavorable for the fail safe of work high above the ground, instrument volume is larger, and inconvenience is carried in work high above the ground, screw thread is higher to the material requirements of expansion link, and screw thread service time is long easily skids.
Utility model content
The utility model is to provide a kind of specific purpose tool of changing double bundle conductor conductor spacer, and while making work high above the ground, the operation of restringing conductor spacer is more simple and direct, saves the operating time, increases work efficiency.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
Change the specific purpose tool of double bundle conductor conductor spacer, comprise that end is provided with the hook bar of hook and the drag hook bar that end is provided with drag hook, also comprise a lever handle, one end of lever handle is provided with at least two axis holes, the end of the end of described hook bar and drag hook bar is also respectively arranged with axis hole, and the axis hole on lever handle is hinged with axis hole and the axis hole on drag hook bar on hook bar by rotating shaft respectively; The other end of lever handle is provided with the tight locking button that can coordinate with hook bar, described tight locking button is a crotch, one end of crotch is hinged in the top pin-and-hole of lever handle, the other end of crotch is made and the shape of linking up with bar and coordinating, and tight locking button is locked on hook bar when the back direction of hook bar is drawn close at lever handle.
Further improvement of the utility model is: the relative position of hook bar and drag hook bar be make hook and drag hook the relative opening of back in the opposite direction.
Further improvement of the utility model is: described axis hole all arranges length direction spread configuration a plurality of and edge hook bar or drag hook bar on hook bar and drag hook bar; 3 axis holes are also at least set on lever handle.
Further improvement of the utility model is: the main body that described lever handle arranges the relative lever handle in one end of rotating shaft has certain camber, and the rotating shaft of inner side on lever handle is arranged on turning.
Owing to having adopted technique scheme, the obtained technological progress of the utility model is:
The utility model adopts lever handle as the retractor device of hook and drag hook, during work high above the ground, only need fasten two steps of hook bar by lever handle pull-up with by tight locking button, simple operating steps, saved the operating time, one hand can operate, and can make the other hand of work high above the ground personnel free for stablizing health, has reduced work high above the ground difficulty, while having solved former use rotary extension instrument, need bimanualness, the problem that work high above the ground personal security is low.Lever handle is without cutting thread, and low to the requirement of insulating material material, lever handle can fold, and instrument volume is little, is convenient to work high above the ground and carries.The tight locking button of installing on lever handle is made crotch-shaped, simple to operate, and work high above the ground personnel one hand can operate, and tight locking button plays fixation to instrument, has strengthened maintainer's operational security.
The axis hole of the utility model instrument all arranges length direction setting a plurality of and edge hook bar or drag hook bar on hook bar and drag hook bar; 3 axis holes are also at least set on lever handle, the distance between hook and drag hook can be regulated, go for the different bundle conductor of sub-conductor distance, when the distance of sub-conductor is non-zero .4m, also can use.
The hook of the utility model instrument and drag hook are in the opposite direction, above sub-conductor above the back of linking up with during use hangs over and is positioned at, the back of drag hook from be positioned at below sub-conductor below hang into, make lever handle in upper and lower drawing process, the back of hook and drag hook is all pushed down wire, wire is not easy to deviate from from hook, facilitates high-altitude application.
The rotating shaft end of lever handle is certain camber, when lever handle is closed up, can be adjacent to clevis arm, has reduced the length of tight locking button, has reduced work high above the ground personnel's scope of activities.
