Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not paying the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in figures 1-4, a kind of strain tower drainage thread does not break construction method, carries out in the following manner:
(1) collect exhaling of strain tower in circuit and claim high, overall height and span, calculate wire according to unwrapping wire sag and span and return and lead reserved value, row labels of going forward side by side; Return and lead reserved value and calculate according to power industry safety work code requirement.
(2) in mark, preformed armor rods strain clamp is installed, preformed armor rods strain clamp is connected with connecting plate 1, connecting plate 1 is connected with U-shaped connector 2, U-shaped connector 2 is connected on the insulator string 3 of strain tower, wherein preformed armor rods strain clamp comprises thimble 4 and preformed armor rods 5, and preformed armor rods is connected with drainage thread 6.In thimble and preformed armor rods junction, note making wire freely sagging under gravity, form turning round of wire and wire jumper, can not torsion guidewire by force, otherwise easily occur that broken lot, wire can be dawdled thimble.
Described thimble 4 is the thimble of carbon steel.The percentage elongation of carbon element steel is good, is about 18%, can prevent thimble from rupturing and cause wire dropping.After adopting preformed armor rods strain clamp of the present invention, when coaster crossed by wire, do not need water pipe precaution; During stringing, wire jumper carries out back leading reserved according to precalculated numerical value, directly carries out installation exercise, do not need marcottage job platform, be convenient to balance line after drawing print, promotes transmission line construction overall process Mechanization Level.
In the present invention, thimble is avoided directly to be connected with the triangle yoke plate on shaft tower, because in this connected mode drainage thread can only in the plane at set square place flexible rotating, when wire occurs that torsion or workman's operation maintenance scrunch wire, thimble will be subject to bending stress, may cause the damage of thimble time serious.Therefore, the present invention utilizes U-shaped connector 2 to be connected with shaft tower by thimble with connecting plate 1, and connecting wire like this at horizontal and vertical directions flexible rotating, can prevent the fracture of thimble.The length of U-shaped connector is wanted suitably, can draw smoothly provide sufficient space, outgoing direction and thimble place plane orthogonal under the drawing of wire for wire from wire clamp outlet.
As preferably, be also provided with internal layer protection preformed armor rods between preformed armor rods 5 and drainage thread 6, internal layer protection preformed armor rods is wrapped on drainage thread 6, and preformed armor rods 5 is wrapped on internal layer protection preformed armor rods.Increase internal layer protection preformed armor rods as ceiling, drainage thread skin not only can be protected not to be worn, and improve the rigidity of drainage thread, avoid producing wire external layer broken lot when preformed armor rods skin bar is installed.
Preferably, be provided with in the junction of preformed armor rods 5 and drainage thread 6 transducer detecting drainage thread temperature and tension force.This kind of intelligent transducer can detect wire temperature rise, wave, ice coating and running tension, power transmission line intelligent level can be promoted.
In addition, the present invention is corner inside and outside strain tower 9, is provided with and hangs insulator string 8, and hang insulator string 8 and be connected with the wire jumper section of drainage thread by suspension clamp, wire jumper section is also connected with weight 7.Can get loose by mode preformed armor rods like this, increase second protection.
Preferably, can also at drainage thread and preformed armor rods contact site coated with conductive sand or conductive grease, to reduce contact resistance.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
