Abstract
The utility model discloses a kind of be exclusively used in transmission line of electricity is housed steel tower on earth potential working cat ladder, its design feature is: cross bar and mobile jib weld together, two, left and right hook and cross bar be screwed connection; Mobile jib from top to bottom left and right is provided with little cross bar, can dismantle, be divided into upper and lower two parts in the middle of mobile jib; Mobile jib is middle bottom an aperture, and aperture binds an insulating cord, and whole earth potential working cat ladder is made by insulated pipes used.The utility model has the advantages that: this earth potential working cat ladder be use simply, lightly nimble, safe and reliable, the complementary tool of delicate structure, staff can utilize this instrument arbitrarily to adjust job position on the steel tower of high-altitude hollow out, avoid operation because of well can not arrive job position thus can not carry out livewire work or by force operation cause the risk of falling from high altitude, and significantly shorten the time of livewire work, improve the safety factor of livewire work, have broad application prospects.
Description
Technical field
The utility model relates to instrument on a kind of steel tower for being equipped with transmission line of electricity, be specifically related to a kind of be exclusively used in transmission line of electricity is housed steel tower on earth potential working cat ladder.
Background technology
Because transmission line of electricity is erected at wilderness and mountain driving mostly, circuit is by way of special areas such as minefields, therefore thunderstorm season, circuit is struck by lightning, in order to ensure the safe operation of transmission line of electricity, must according to " DL/T 741-2010 overhead transmission line operating standard ", the object changed is needed to change to the walking along the street that can not run or other, but when operating on the steel tower of high-altitude, all hollow out in the middle of major part steel tower, staff is difficult to operate when hollow out, mode of operation is in the past all generally that staff slowly steps on the very difficult operation in steel tower two limit of hollow out, inefficiency is not said, also be easy to out security incident, when particularly needing the steel tower upper end to hollow out to operate, especially not easily, this technology is exactly invent " simple to operate based on above shortcoming, safe and reliable, easy to carry " auxiliary substitute instrument.
Summary of the invention
The purpose of this utility model be to provide a kind of be exclusively used in transmission line of electricity is housed steel tower on earth potential working cat ladder, this earth potential working cat ladder structure is simple, easy to use, avoid operation because of well can not arrive job position thus can not carry out livewire work or by force operation cause the risk of falling from high altitude.
The utility model is achieved like this, a kind of be exclusively used in transmission line of electricity is housed steel tower on earth potential working cat ladder, mainly comprise hook, cross bar and mobile jib; It is characterized in that: cross bar and mobile jib weld together, two, left and right hook and cross bar are screwed connection; Mobile jib from top to bottom left and right is provided with little cross bar, can dismantle, be divided into upper and lower two parts in the middle of mobile jib; Mobile jib is middle bottom an aperture, and aperture binds an insulating cord, and whole earth potential working cat ladder is made by insulated pipes used.
Design of the present utility model can set earth potential working cat ladder length freely according to need of production.
The utility model has the advantages that: this earth potential working cat ladder be use simply, lightly nimble, safe and reliable, the complementary tool of delicate structure, staff can utilize this instrument arbitrarily to adjust job position on the steel tower of high-altitude hollow out, avoid operation because of well can not arrive job position thus can not carry out livewire work or by force operation cause the risk of falling from high altitude, and significantly shorten the time of livewire work, improve the safety factor of livewire work, have broad application prospects.
Accompanying drawing explanation
Fig. 1 is structural front view of the present utility model.
Fig. 2 is structure left view of the present utility model.
In the drawings, 1 is cross bar, and 2 is hook, and 3 is mobile jib, and 4 is little cross bar, and 5 is insulating cord, and 6 detachably locate for mobile jib.
Detailed description of the invention
As shown in Figure 1 and Figure 2, the utility model comes work and enforcement like this, a kind of be exclusively used in transmission line of electricity is housed steel tower on earth potential working cat ladder, mainly comprise cross bar 1, hook 2 and mobile jib 3; It is characterized in that: cross bar 1 and mobile jib 3 weld together, two, left and right hook 2 and cross bar 1 are screwed connection; Mobile jib 3 from top to bottom left and right is provided with little cross bar 4, and can dismantle in the middle of mobile jib 3,6 detachably locate for mobile jib, is divided into upper and lower two parts (mobile jib can be dismantled, and is convenient to change dissimilar hook, is applicable to multiple steel tower type); Mobile jib 3 is middle bottom an aperture, and aperture binds an insulating cord 5.
During use, earth potential working cat ladder upper end hangs on the horizontal material of steel tower by hook, and lower end utilizes insulation rope to be bundled in tower material of iron tower infall.Earth potential working personnel can utilize cat ladder arbitrarily to adjust job position on steel tower.
The utility model earth potential working cat ladder is most preferred to be of a size of; Cross bar length 50cm, width 5cm, hook length 10cm.The total length of mobile jib is 270cm, and little cross bar length is 18cm, is specially 20cm between little cross bar and little cross bar.
