Abstract
A drooping radian regulator comprises a wire stretcher 1, a grip holder 2, and a traction-type dynamometer 3, wherein one end of the traction-type dynamometer 3 is connected with the wire stretching end of the wire stretcher 1, and the other end of the traction-type dynamometer 3 is connected with the connecting end on the grip holder 2. The utility model equips different working personnel with the same ability to regulate the drooping radian of the wire to be unified and correct, thereby removing the potential safety hazard.
Description
Technical field
The utility model relates to a kind of electrical network wiring tool, and particularly a kind of electric wire is installed the instrument of adjusting.
Background technology
At present generally be to use wire grip that the sagging radian of electric wire is adjusted, sagging radian is relevant with the sagging distance of electric wire, the big more then sagging radian of the sagging distance of electric wire is big more, the staff is fixed on wire grip on the electric pole during adjustment, the adjustment end of electric wire is connected on the chuck that is connected with wire grip, adjust the sagging radian at electric wire middle part by the wire grip take-up, sagging radian can not be too little, too little meeting causes electric wire and ruptures because expand with heat and contract with cold, sagging radian can not be too big, the weight that too big words can make the electric wire two ends bear is excessive, can cause the electric wire of hanging portion to wave when having strong wind to blow over or rupture, security incident takes place, and the selected of sagging radian generally is to use theodolite in typical span, scale and personnel cooperate estimation to measure.The deficiency of this technology has: the several staff of measurement needs of (1) this radian cooperatively interact and measure, and lose time and manpower, adjust two people of one section minimum needs of electric wire in this way, just can mix up about 50 minutes; (2) because sagging radian is to estimate in typical span, and to measure sagging radian generally be that experience by the staff judges that the different sagging radian differences that the staff determined is so be easy to generate the sum of errors potential safety hazard.
Summary of the invention
The purpose of this utility model just provides a kind of sag adjuster, and it can both unify different staff and accurately, eliminates safe hidden trouble when adjusting the sagging radian of electric wire.
The purpose of this utility model is to realize that by such technical scheme it includes wire grip, chuck and draw-bar donamometer, and an end of draw-bar donamometer links to each other with the backguy end of wire grip, and the other end of draw-bar donamometer links to each other with link on the chuck.
Before the line transfer, earlier calculate the stress intensity that electric wire should bear by formula N=S* δ p/K, wherein S by the cross-sectional area of use electric wire, δ p is a lead momentary breakdown stress, K is the coefficient of safety under the Current Temperatures, δ p and K table look-up and can get.During line transfer, the utility model is fixed on the electric pole at electric wire adjustment end place, the adjustment member of electric wire links to each other with chuck, adjust the stress intensity of electric wire by the wire grip take-up, any staff can read the current stress intensity that bears of electric wire by draw-bar donamometer, only needs the operation wire grip that the reading of draw-bar donamometer is adjusted into the size that is calculated before.Entire work process only needs a people just can finish, and has saved manpower, directly determines the degree of take-up by draw-bar donamometer, has saved estimation and has adjusted the required time, adjusts one section electric wire with the utility model and only needs about 30 minutes.Only need judge the sagging radian of electric wire when take-up by draw-bar donamometer, convenient directly perceived, any staff can adjust unified sagging accurately radian, has eliminated the error that estimation is caused.
Owing to adopted technique scheme, the utlity model has following advantage: (1) has saved manpower and time; (2) the radian adjustment is intuitively accurate, has significantly improved fail safe.
