Increase be a kind of requirement is extremely stringent and security requirement is high operation, have lightning conducter needs above ultra-high-tension power transmission line
When installation or replacement, can not even more it adopt a casual attitude.
With greatly developing for power grid, high-tension line is more and more, and the leap of new route also becomes increasingly complex, power supply
Safety, reliability requirement are higher and higher naturally, wherein the timely installation of lightning conducter and inspection replacement are the most important things.No
It is evitable to be, in the lower section of lightning conducter, may is that criss-cross arterial traffic, may is that pavilions, terraces and open halls by a stream in front and a hill at the back,
May is that the railway of wonderful workmanship excelling nature, may is that the golden yellow crops of rice wave etc., " crossing over problem " ultra-high-tension power transmission line lightning conducter more
In changing jobs, it appears protrusion especially with it is important.If being filled during replacing lightning conducter on high voltage transmission line road without block
The protection set, falling down for lightning conducter will greatly influence the reliability of power supply, also will bring weight to the safety and economy of user
Big loss causes immeasurable consequence.
When having span line construction above ultra-high-tension power transmission line, traditional block operation mode is using steel strand wires as material
Material, is ridden over by two operating personnels and is set up on conducting wire, after the completion of construction, then by two staff takes same work
Industry mode fetches block device.However, there are poles by two staff of high voltage transmission line road during this high altitude operation
Big security risk, especially when route is higher, the more notable increase of the difficulty of operation, security risk grade is also more tight
It is high.
The operation mode takes a long time, if staff is because of uncomfortable suddenly or fault, it will cause hardly imaginable
Serious consequence；It is skidded accidentally due to weather or the brings consequences such as heatstroke will also be difficult to imagine, and thought in following people
It is also extremely difficult for suing and labouring.
In addition, the operating technology content of the work with requirements such as staff's own bodies quality or ages be also it is high,
Many people are difficult to be competent at this task.Even if being operated by two skilled staff, Master Cost and work difficulty are same
It is unable to describe in words.In addition steel strand wires are than cumbersome, hardness is also bigger, it is difficult to recycle, transport, be arranged, adjustment difficulty it is also bigger,
The labour's intensity for consuming people is naturally larger.Thus, using the safety of the operation mode of traditional block device, progress, warp
Ji property is all poor.
Summary of the invention
Technical problem to be solved by the utility model is: providing a kind of cunning for ultra-high-tension power transmission line quick close-up device
Wheel can be convenient using the pulley, efficiently pulley is suspended on conducting wire, then several pulleys are connected together with insulating cord, just
A block device is constituted, the organization work of effective is reached, avoids casualties and financial losses to greatest extent, is tieed up
Protect the normal operation of high altitude operation, the above-mentioned problem of effective solution.
The technical solution of the utility model are as follows: a kind of pulley for ultra-high-tension power transmission line quick close-up device, it includes
The top of the pulley base and pulley of square frame-shaped, the pulley base is equipped with pulley spindle, and pulley sleeve is on pulley spindle, at the bottom of pulley base
End is intermediate to be equipped with through-hole, is equipped with connecting rod in through-hole, the bottom end of the connecting rod is fixedly connected with becket bridle, in the lower part side of pulley base
Equipped with metallic channel one, conducting wire is equipped on the position of metallic channel one and is locked.
The centre of the pulley is equipped with U-shaped metallic channel two.
The top of the connecting rod is equipped with screw thread, is located on through-hole by upper lower nut.
The bottom end of the conducting wire lock is hinged on the bottom end side of pulley base by pin shaft, and the top side of conducting wire lock is equipped with
U type slot, the U type slot is interior to be equipped with stud, and described stud one end is fixed on the side of pulley base, and the outside of stud is equipped with
Wing nut.
The beneficial effects of the utility model are: compared with prior art, using the technical solution of the utility model, the present apparatus
Structure is simple, easy for installation, cheap, for ensureing that the safety of high-tension transmission line spanning construction has vital meaning
Justice, the research and development application of the achievement set up the important time across object crossing frame when substantially reducing transmission line of electricity replacement lightning conducter,
Compared with traditional work mode, the novel quick close-up device set-up time is shorter, about 10 minutes one group, labor intensity is low, makees
Industry personnel's person risk is smaller, and environmentally protective reusable, greatly improves operating efficiency, can shorten route to the maximum extent
