Abstract
A tool used for fastening 220kv strain wire clamp bolt is used for solving the problems of clumsy property and low operating safety of the existing tools. The technical proposal is as follows: the tool consists of at least one operating rod, a metal connecting plate, a fastening wrench and a control rope, wherein, the operating rod is connected with the fastening wrench at the front end by the metal connecting plate, and the control rope is connected to the upper end of the fastening wrench. The tool has the advantages of safety and reliability, simpleness and feasibility, convenient operation, labor and time conservation, and the like. Moreover, the tool can replace the operating rod with an insulating operating rod for electriferous fastening, therefore, the power-off time is greatly saved and the technical progress effect is significant.
Description
Technical field
The utility model relates to a kind of ultra-high-tension power transmission line construction tool.
Background technology
The 220kv strain clamp is to be used for lead fixed on the strain insulator string of non-rectilinear shaft tower, plays the anchoring effect and as electric conductor.When passing through maximum permissible current for a long time under rated voltage, the temperature rise of wire clamp should be not more than the temperature rise of the lead that is mounted; When bearing electrical load, its ampacity should be not less than the ampacity that is mounted lead, and should connect reliable.The 220kv ultra-high-tension power transmission line is self-evident as its importance of basic routing line.All tackling the strain clamp bolt every year for the safe operation that guarantees circuit carries out comprehensively fastening good to guarantee that it connects.But in recent years, 220kv circuit strain insulator shaft tower almost had been replaced by synthetic insulator all.So because synthetic insulator is originally forbidden to trample as synthetic rubber articles, this just makes troubles for fastening strain clamp working bolt and difficulty.Therefore, present stage many employings in fastening work bundle the modes of hard ladder between lead and cross-arm.This method is very required great effort in the work high above the ground process, and hard ladder is slipped out of the hand or landing easily, and fail safe is not high.In addition,, and need the hard ladder heaviness very of binding because 220kv insulator string length is bigger, single can't carrying out, therefore required personnel are many, labour intensity big, it is long to expend time in, coefficient of safety is low, and are greatly dangerous.
Summary of the invention
The utility model be used to overcome prior art not enough, a kind of safe and reliable, fastening 220kv strain clamp bolt specific purpose tool of being convenient to operate proposed.
Addressing the above problem the technical scheme that is adopted is:
A kind of instrument that is used for fastening 220kv strain clamp bolt, it is made up of at least one action bars, metal connecting plate, spanner and control rope, and wherein, action bars connects the control rope by the spanner of metal connecting plate connection front end in the upper end of spanner.
The above-mentioned instrument that is used for fastening 220kv strain clamp bolt, the front end of described metal connecting plate is equipped with bolt, is connected the hole that the handle of spanner is provided with equal and opposite in direction, is provided with at interval with spanner by bolt, in order to change moment, it is 2400KN that maximum is born moment.
The above-mentioned instrument that is used for fastening 220kv strain clamp bolt, the two sides of described spanner is respectively equipped with the wrench opening of the big stove bolt of fastening difference.
The above-mentioned instrument that is used for fastening 220kv strain clamp bolt, the top of described action bars and metal connecting plate bottom are connected both by screw thread.
The above-mentioned instrument that is used for fastening 220kv strain clamp bolt, described spanner itself are fastening directions that turns to card to control spanner by wrench socket below, thus the problem of the bolt of having avoided being locked repeatedly.
The above-mentioned instrument that is used for fastening 220kv strain clamp bolt, described metal connecting plate tip designs becomes the opening shape, and connecting bolt is housed.
The above-mentioned instrument that is used for fastening 220kv strain clamp bolt, described spanner is by a fastening direction that turns to card to control spanner of wrench socket below.
The above-mentioned instrument that is used for fastening 220kv strain clamp bolt, described action bars moment is output as 25.00N～28.00N, and the best is 26.89N, and the moment scope of its output is far smaller than the intensity of spanner and metal connecting rod.Therefore spanner intensity meets the demands.It is 15cm～20cm that action bars promotes spanner rotation standard, but and repeatable operation.
When the utility model used, operating personnel stood in and utilize the control rope that instrument is enclosed within on the shaft tower cross-arm to need on the fastening bolt, drove spanner and carried out fastening strain clamp working bolt by promoting action bars.
The utility model efficiently solves existing be used for the instrument clumsiness of fastening 220kv strain clamp bolt, the problem that the operator safety coefficient is low.The results showed that it compared with prior art has advantages such as safe and reliable, simple, easy to operate, time saving and energy saving.And this instrument also can be replaced by action bars insulating bar as required and can be carried out charged fasteningly, has saved interruption duration greatly, and the technological progress effect is remarkable.This new tool is applicable to the fastening work of cable clip bolt of 110kv-220kv high-voltage power line tension shaft tower.
Description of drawings
