Description
Technical field
The utility model belongs to mechanical wire tensioning device technical field, more particularly, to a kind of new turnbuckle.
Background technology
In the operation maintenance of power network line, especially high-tension line, the tension of wire is a very important job,
If wire excessively relaxes, wire is unstable, is easily swung when strong wind, and now encountering All other routes will be short-circuit,
Cause transmission of electricity to interrupt, influence social life and industrial production.Now in construction the turnbuckle that generally uses mostly by ratchet bracket,
Ratchet, support hangar, handle, steel wire rope, U-shaped plate washer, pulley, dop composition, U shapes plate washer are located at the steel wire rope of ratchet bracket
Leading-out terminal, it is impossible to rotate, only play a part of to keep off steel wire rope.Support hangar first need to be fixed on to the fixing point of electric pole during operation
On, then with dop by conductor clamping, power transmission line is tensed by a segment distance by rotational handle, at this moment needs manually to draw wire
Tightly, then unclamp dop and clamped after the stringing distance that moves forward, the stringing operation of power transmission line can be completed by constantly repeating this operation, no
Foot part is to need a large amount of support staff, and working condition is poor, and operating efficiency is low.In addition, be used alternatingly using two sets of turnbuckles,
Also the stringing operation of power transmission line can be completed, but exists and carries, look for fixed hanging point and unhandy deficiency.On the other hand, by
Field largely is located in transmission line of electricity, so stringing works mainly by being accomplished manually at this stage, and stringing need of work is climbed up
Shaft tower, because turnbuckle is heavier, the dangerous property of process for turnbuckle of hanging oneself, therefore the length of handle can not be oversize, but face
During to wire compared with thick or distant shaft tower spacing circuit, circuit deadweight is larger, and the torque needed for stringing accordingly increases, manpower
It is difficult to meets the needs of stringing.
