Description

przedmiotem wynalazku, umieszczony jest miedzy dwoma wewnetrznymi powierzchniami szczek, któ¬ re w czasie jego zakleszczania pozostaja zawsze równolegle wzgledem siebie. Powoduje to przyle¬ ganie przewodu do szczek na calej ich wewnetrznej powierzchni i tym samym zapobiega zgniotowi 89 48989 3 przewodu, powstawaniu na nim karbu oraz jego wysliznieciu sie ze szczek.Umieszczone miedzy zewnetrznymi powierzchnia¬ mi szczek a powierzchniami prowadnic korpusu rolki wzglednie kulki lozyska tocznego zapobiegaja zacieraniu sie tych powierzchni, co ulatwia demon¬ taz zabki z przewodu po jego naciagnieciu. Zakla¬ danie i zdejmowanie zabki z przewodu nie wymaga uzycia zadnych dodatkowych narzedzi, jak np. klu¬ cza, a zatem upraszcza i skraca czas pracy. Zabka moze byc zalozona na przewód w znacznym odste¬ pie od slupa, poniewaz zdjecie jej z przewodu moze byc dokonane z odleglosci przez pociagniecie linka przytwierdzona uprzednio do czesci sworznia wy¬ stajacej z tulei.Przedmiot wynalazku pokazany jest w przykla¬ dzie wykonania na rysunku, na którym fig. 1 przed¬ stawia widok zabki z przodu przy jednej jej polo¬ wie odslonietej po zdjeciu pokrywy, fig. 2 — widok zabki z tylu z czesciowym przekrojem tulei.W korpusie 1 umieszczone sa przesuwnie dwie klinowe szczeki 2 o kacie zbieznosci równym katowi zbieznosci prowadnic korpusu. Pomiedzy powierz¬ chniami zewnetrznymi szczek a powierzchniami wewnetrznymi prowadnic korpusu umieszczone sa w koszu 3 rolki 4 lozyska tocznego. Po srodku dlu¬ gosci kosza 3 w wykonanym w nim wzdluznym zaglebieniu umieszczona jest dociskowa sprezyna srubowa 5 zaczepiona o wystep 6 w prowadnicy korpusu, dociskajaca kosz 3 w kierunku zakleszcza¬ nia sie szczek. Na zewnetrznej, tylnej stronie kor¬ pusu 1 zabki w tulei 7, przytwierdzonej swym kon¬ cem sruba 8 obrotowo do korpusu, umieszczona jest dociskowa sprezyna srubowa 9, która poprzez bolec 10 umieszczony w tulei 7, przytwierdzony jednym koncem do jednej szczeki 2 i poprzez ramie 11 przytwierdzone trwale do drugiej szczeki 2 scia¬ ga obie szczeki w kierunku zakleszczania przewodu 489 4 12 linii elektrycznej. Wewnetrzne powierzchnie szczek 2, pomiedzy którymi umieszcza sie przewód 12, maja wzdluzne pólkoliste wyzlobienia, dzieki czemu zwiekszona jest powierzchnia przylegania do przewodu i dzieki czemu przewód nie jest zgnia¬ tany. PLaccording to the invention, it is placed between two inner surfaces of the jaws, which always remain parallel to each other during the jamming. This causes the conductor to adhere to the jaws over their entire inner surface and thus prevents the conductor from crushing, notching and slipping from the jaws. Located between the outer surfaces of the jaws and the guide surfaces of the roller body or the ball of the rolling bearing. prevent galling of these surfaces, which makes it easier to remove the tab from the cable after it is stretched. Placing and removing the tab from the conduit does not require the use of any additional tools, such as a wrench, and therefore simplifies and shortens the working time. The toy can be attached to the cable at a considerable distance from the pole, because its removal from the cable can be made from a distance by pulling the cable previously attached to the part of the pin protruding from the sleeve. The subject of the invention is shown in the example in the drawing, in which Fig. 1 shows a front view of the tab with one half of it exposed after the cover has been removed, Fig. 2 - a rear view of the tab with a partial cross-section of the sleeve. In the body 1 there are slidably placed two wedge jaws 2 with a converging angle taper angle of the body guides. Between the outer surfaces of the jaws and the inner surfaces of the body guides, 3 rollers and 4 rolling bearings are placed in the basket. In the middle of the length of the basket 3, in the longitudinal recess made therein, a compression coil spring 5 is inserted, engaged by the projection 6 in the body guide, pressing the basket 3 in the direction of the jaws jamming. On the outer, rear side of the body 1, in the sleeve 7, the screw 8 rotatably fixed to the body with its end, there is a compression coil spring 9, which through a pin 10 placed in the sleeve 7, fixed at one end to one jaw 2 and by the arm 11 permanently attached to the second jaw 2 draws both jaws in the direction of jamming the conductor 489 12 of the electric line. The inner surfaces of the jaws 2, between which the wire 12 is placed, have longitudinal semicircular grooves, thanks to which the contact surface with the wire is increased and so that the wire is not crushed.

Claims

Claims 10 1. A buckle for tensioning the cables of overhead power lines, consisting of a body having two converging inner guides, of two slidably converging wedge jaws arranged therein, and articulated to the body of the tendon, characterized by the fact that the body guides (1) and the outer surfaces of the jaws (2) are fitted with rollers or balls (4) of the rolling bearing in the basket (3), in the center of which, in the longitudinal cavity made in it, a pressure coil spring (5 ), hooked to the protrusion (6) of the body, and on the outer, rear side of the body (1) in the sleeve (7), the screw (8) rotatably fixed to the body with its end, there is a pressure coil spring (9), which through the pin (10), placed in the sleeve (7), the screw (8) rotatably fixed to the body with its end, there is a pressure coil spring (9) which, through a pin (10) placed in the sleeve (7) When it is cut at one end to one jaw (2) and through a frame (11) firmly attached to the other jaw (2), it exerts pressure on both jaws in the direction of the wire (12) jamming. 35

2. A toy according to claim The method of claim 1, characterized in that the inner surfaces of the jaws (2) adjacent to the taut wire have longitudinal, semicircular grooves with a smooth surface 89,489%. 1 Fig 2 PL
