Description
Technical field
The present invention relates to a kind of ADSS optical cables installation auxiliary device, more specifically, it relates to a kind of steel tower ADSS light
Cable unloads power apparatus.
Background technology
At present, ADSS optical cables are set up with electric power tower, and optical cable per level-one steel tower by gold utensil with fixing, and both ends steel tower is with
Between angle tower ADSS optical cables are gripped so as to bear the running tension of optical cable using strain hardware fitting, the tangent tower of center section is using outstanding
The gold utensil that hangs down hangs ADSS optical cables and is not subject to the running tension of optical cable.For steel tower, ADSS optical cables get over its horizontal pull
Small better, pulling force, which crosses senior general, influences the stability of steel tower, and we can only rely on the degree for adjusting optical cable stringing now, pass through increasing
Big arc sag, reduces the pulling force to steel tower.But ADSS optical cables operations specification has optical cable arc sag on strict demand, the excessive easy band of arc sag
Carry out problems, such as：Lower safe distance is reduced, optical cable windage yaw increases, optical cable abrasion aggravation etc..Therefore, up to the present,
A kind of effective method is at home and abroad there is no, to reduce pulling force of the ADSS optical cables to steel tower.
Chinese patent notification number CN204832624U, discloses a kind of high voltage overhead power transmission sequence ADSS optical fiber cable fitting strings
And its connection structure, including at least ADSS optical cables and for fixing the preformed armor rods wire clamps of ADSS optical cables, further include be connected to it is pre-
The connector of hank knotting wire clamp, be connected to the hanging plate of connector with and be serially connected with the link for being used to fix with shaft tower of hanging plate, link
It is embedded in hanging plate.Can constantly it be flowed at any time withouyt insulator, the alternation electric charge of ADSS optical cables appearance sensing in hardware string
Enter ground, avoid due to the alternation electric charge of accumulation is breakdown and the problem of scorification optical cable, improve the security of optical cable operation,
Optical cable operating cost is saved at the same time.But it is not suitable for middle angle tower, easily there is arc using rear ADSS optical cables for a long time
Vertical excessive phenomenon.
The content of the invention
The present invention overcomes both sides deficiency, when, when ADSS optical cables are installed on steel tower, to the horizontal pull of steel tower
It is larger, influence the stability of steel tower；Second, easily there is the excessive phenomenon of arc sag using rear ADSS optical cables for a long time, there is provided one
Kind steel tower unloads power apparatus with ADSS optical cables, and ADSS optical cables are installed on steel tower by unloading power apparatus, substantially reduce the water to steel tower
Horizontal drawing power, reduces the influence to iron tower stability, and ADSS optical cable arc sags it is excessive when can adjust automatically unload power apparatus
Length, so as to tense ADSS optical cables, reduces ADSS optical cable arc sags, ADSS optical cables is less prone to the excessive phenomenon of arc sag.
In order to solve the above-mentioned technical problem, the present invention uses following technical scheme：A kind of steel tower unloads power with ADSS optical cables and fills
Put, including connecting rod, be connected to length-adjustable two adjusting rod in connecting rod both ends, the pulling ring being connected on adjusting rod,
Two pulling rings are all connected with, for the support ring on steel tower, pulling ring activity to be hooked in support ring, pull and are connected on ring
Tension has preformed armor rods, preformed armor rods connection ADSS optical cables, and two preformed armor rodses tense connecting rod.
When ADSS optical cables are installed on steel tower, first support ring is installed on steel tower, preformed armor rods connection is fastened to ADSS
On optical cable, then preformed armor rods end is connected to and is pulled on ring, the length of adjusting rod is adjusted, makes connecting rod, adjusting rod, preformed armor rods
In tension, while ensure that the arc sag of ADSS optical cables is met the requirements.What support ring was subject to according to force analysis is preformed
Silk horizontal pull f=2sin（0.5a）* F, a are preformed armor rods and connecting rod extended line angle, and F is preformed armor rods pulling force, that is, ADSS
The running tension of optical cable.As can be seen from the above equation, when preformed armor rods and connecting rod extended line angle are 0 degree, what support ring was subject to
Preformed armor rods horizontal pull f is 0, unloads power completely, steel tower is solely subjected to the gravity from ADSS optical cable vertical directions at this time；Work as preformed armor rods
When being less than 60 degree with connecting rod extended line angle, f<F, has the effect for unloading power, and steel tower bears vertical from ADSS optical cables at this time
The less pulling force of gravity and horizontal direction in direction；When preformed armor rods and connecting rod extended line angle are more than 60 degree, f>F does not possess
The effect of power is unloaded, steel tower bears gravity from ADSS optical cable vertical directions and the larger pulling force of horizontal direction at this time.Therefore
ADSS optical cables ensure that preformed armor rods is less than 60 degree with connecting rod extended line angle a when installing, when angle a is zero degree, i.e., in straight line iron
When power apparatus is unloaded in installation on tower, steel tower can use strain insulator gold on tangent suspension tower at this time from the horizontal pull of ADSS optical cables
Tool makes ADSS optical cable static sides, advantageously reduces ADSS optic cable designs, difficulty of construction, lifts ADSS optical cable project benefits.Steel tower
The gravity for the vertical direction being subject to does not interfere with the stability of steel tower.In conclusion ADSS optical cables are pacified by unloading power apparatus
Mounted in steel tower, the horizontal pull to steel tower is substantially reduced, reduces the influence to iron tower stability, is conducive to extend steel tower
