Abstract
The utility model discloses a kind of iron towers of overhead power transmission lines anti-theft foot-nail, the pin solving a large amount of iron tower of power transmission line of existing electrical network often follows closely the problems such as stolen, it is characterized in that: the small sircle hole that dowel silk is set on pin rivet nut (1) front end screw rod (2), and semi-circular recesses (5) is set vertically in side, the small sircle hole (6) of interspersed iron wire is set in the side of movable nut (4).There is the advantages such as rational in infrastructure, with low cost, easy for installation, safe and reliable, can be widely used on the power line tower of all different electric pressures of electrical network.
Description
One, technical field
The utility model belongs to electric power transmission line supporting facility, relates in particular to a kind ofly ensure electric transmission line by the iron towers of overhead power transmission lines anti-theft foot-nail of outside destroy.
Two, background technique
At present, power grid construction is advanced by leaps and bounds, aerial power transmission line spreads all over Huang gang the earth, the pin nail of power line tower is installed the long-term normal screws that adopts and is directly positioned on steel tower, power line tower is in field, wilderness, constantly there is pin in recent years and follow closely stolen phenomenon, cause operation maintenance and maintenance to be difficult to carry out, sometimes also security incident can occur.And bring a large amount of economic loss to power-generating enterprise, directly cause enterprise production and management cost increase.
Three, summary of the invention
The purpose of this utility model is exactly the iron towers of overhead power transmission lines anti-theft foot-nail making circuit annex safe antitheft.
The technical solution of the utility model: it is made up of pin rivet nut, screw rod, hold-doun nut and movable nut etc., pin rivet nut front end screw rod arranges the small sircle hole of dowel silk, and in side, semi-circular recesses being set vertically, the diameter of this semi-circular recesses is 2.5 ~ 4 millimeters.The diameter arranging interspersed iron wire in the side of movable nut is 3 ~ 4.5 millimeters of small sircle holes.
Effective effect of the present utility model is: owing to being provided with semi-circular recesses in screw rod one side, embed in groove with nut after iron wire less for hardness can being inserted by the small sircle hole be arranged on movable nut, make the fastening foot nail be arranged on steel tower adopt general purpose tool cannot dismantle, thus it is stolen to effectively prevent field iron tower in power transmission line material at all.There is the advantages such as rational in infrastructure, with low cost, easy for installation, safe and reliable, can be widely used on the power line tower of all different electric pressures of electrical network.
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Four, accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1 is pin rivet nut, 2 is screw rod, and 3 is hold-doun nut, and 4 is movable nut, and 5 is groove, and 6 is small sircle hole.
Five, embodiment
As shown in Figure 1, producing on the traditional steel tower pin be made up of pin rivet nut 1, screw rod 2, hold-doun nut 3 and movable nut 4 nail basis, pin rivet nut 1 front end screw rod 2 arranges the small sircle hole of slotting 3 millimeters of crude iron silks, and the semi-circular recesses 5 that diameter is 3 millimeters is set vertically in side, arrange diameter in the side of movable nut 4 be 3.5 millimeters of small sircle holes 6 for interspersed 3 millimeters of iron wires simultaneously.When implementing the utility model, when line maintenance staff installs, only need first common tightening nut 3 to be tightened on the screw rod of pin rivet nut 1 front end, again screw rod 2 end is inserted pin nail mounting hole on tower material of iron tower, then traveling nut 4 is screwed on screw rod 2, the small sircle hole 6 being arranged on traveling nut 4 side is made to aim at the small sircle hole being arranged at front end on screw rod 2, again by diameter 3mm, the iron wire of long 20mm is inserted by the small sircle hole 6 on traveling nut 4, traveling nut 4 is tightened by use instrument, iron wire is embedded into and is arranged in the axial semi-circular recesses 5 in screw rod 2 side under the rotating force effect of traveling nut 4, make itself and tower material fastening, its anti-theft effect highly significant, the safe antitheft of steel tower can be ensured.If because of need of work must remove time, carry hydraulic pressure reaming removal tool by line maintenance workman namely detachable, can one-man service, fast and easy.
