Description

2 'íï Ûf/3 För det angivna ändamålet utmårks topplinvagnen enligt föreliggande uppfinning i. huvudsak: därav, att linvagnen består av en i linvagnens ändvy sett L-formig bärare och en vid den yttre änden av bärarens horisontella L-balk medelst en skruv eller något liknande fästelement fastsatt, i allt väsentligt plan spännplatta, som tillsammans med den L- formiga bäraren bildar en U-profil, i vilken två stödrullar är roterbart lagrade på axlar, vilka även tjänar till sam- manhållning av bäraren och spännplattan, varvid fästorganet för hopfästning av änden på bärarens horisontella L-balk och spännplattan ligger i ett horisontellt plan avsevärt nedan- för det horisontella plan, i vilket stödrullarnas axlar är belägna. For the stated purpose, the top trolley according to the present invention is distinguished mainly by the fact that the trolley consists of an L-shaped carrier seen in the end view of the trolley and one at the outer end of the horizontal L-beam of the carrier by means of a screw or fixed fastening element, substantially planar clamping plate, which together with the L-shaped carrier forms a U-profile, in which two support rollers are rotatably mounted on shafts, which also serve to hold the carrier and the clamping plate together, the fastening means for The attachment of the end of the carrier's horizontal L-beam and the clamping plate lies in a horizontal plane considerably below the horizontal plane, in which the axes of the support rollers are located.

Det är enligt uppfinningen lämpligt att stödrullarnas axellinjer ligger på ett avstånd från varandra motsvarande minst 2,5 - 3 gånger stödrullarnas största diameter.According to the invention, it is suitable that the axis lines of the support rollers are at a distance from each other corresponding to at least 2.5 - 3 times the largest diameter of the support rollers.

Uppfinningen kommer att förklaras närmare i det följan- de med hänvisning till bifogade ritning, på vilken en såsom exempel vald utföringsform av en topplinvagn enligt uppfin- ningen visas.The invention will be explained in more detail in the following with reference to the accompanying drawing, in which an exemplary embodiment of a top line trolley according to the invention is shown.

Fig. 1 är en perspektivvy av topplinvagnen enligt uppfinningen: Fig. 2 är en ändvy av topplinvagnen i fig. 1: Fig. 3 är en sidovy av topplinvagnen, sedd i riktning av pilen A i fig. 2; Fig. 4 visar ett delsnitt av linvagnen, tagit i planet Iv-Iv i fig. 1.Fig. 1 is a perspective view of the top line carriage according to the invention: Fig. 2 is an end view of the top line carriage in Fig. 1: Fig. 3 is a side view of the top line carriage, seen in the direction of the arrow A in Fig. 2; Fig. 4 shows a partial section of the cable carriage, taken in the plane Iv-Iv in Fig. 1.

Topplinvagnen enligt föreliggande uppfinning består av en i ändvy L-formig bärare 10 av stansad och formpressad tunnplåt. Med uttrycket tunnplåt förstås i föreliggande fall en företrädesvis dubbelsidigt galvaniserad stálplåt med en tjocklek av ca. 0,25 - 0,75 mm. Vidare består topplinvagnen av en spännplatta ll, likaledes av tunnplåt.The top line trolley according to the present invention consists of an end-view L-shaped carrier 10 of punched and molded sheet metal. In the present case, the term sheet metal is understood to mean a preferably double-sided galvanized steel sheet with a thickness of approx. 0.25 - 0.75 mm. Furthermore, the top line trolley consists of a clamping plate 11, likewise of sheet metal.

Bärarens 10 horisontella balk 10B är vid sin yttre ände ombockad nedåt till ett fästöra 10C, som är fäst vid spänn- plattans 11 undre kant medelst en skruv 15 med mutter.The horizontal beam 10B of the carrier 10 is bent downwards at its outer end to a fastening lug 10C, which is fastened to the lower edge of the clamping plate 11 by means of a screw 15 with a nut.

Bäraren 10 med sin vertikala "L-stapel" 10A och horisontella "L-balk" 10B bildar tillsammans med spännplattan 11 en U- f.) \'í 3 Ü profil, sett i ändvy, i vilken profil två stödrullar 12, 13 är roterbart lagrade. Dessa stödrullaras mantelytor är på sedvanligt sätt inåtbuktande, varigenom bildas ett spår för upptagande av den elledning eller kabel, som är under drag- ning. Det inbördes avståndet i horisontell led mellan stöd- rullarnas 12, 13 axellinjer uppgår i det visade fallet till ca. 2,5 - 3 gånger rullarnas största diameter, vilket av- stånd för vissa tillämpningar kan ökas något. Detta avstånd är viktigt för att man skall undvika otillåtet skarpa bock- ningar av ledningen eller kabeln under den första fasen av dennas dragning.The carrier 10 with its vertical "L-pile" 10A and horizontal "L-beam" 10B together with the clamping plate 11 forms a U-f.) 3 profile, seen in end view, in which profile two support rollers 12, 13 are rotatably mounted. The mantle surfaces of these support rollers are inwardly bulging inwards, as a result of which a groove is formed for receiving the power line or cable which is being pulled. The mutual distance in the horizontal direction between the axis lines of the support rollers 12, 13 in the case shown amounts to approx. 2.5 - 3 times the largest diameter of the rollers, which distance for certain applications can be increased slightly. This distance is important to avoid unintentionally sharp bends of the wire or cable during the first phase of its routing.

Såsom framgår av ritningen, speciellt fig. 2, är spänn- plattan 11 i allt väsentligt plan. Utmed sina kanter har såväl bäraren 10 som spännplattan 11 förstyvande utbock- ningar eller sickor, vilket visas av sickan 14 i fig. 4 och som även torde framgå av fig. 1-3.As can be seen from the drawing, in particular Fig. 2, the clamping plate 11 is substantially planar. Along its edges, both the carrier 10 and the clamping plate 11 have stiffening bulges or sickles, which is shown by the sickle 14 in Fig. 4 and which should also be shown in Figs. 1-3.

Bärarens 10 vertikala L-stapel 10A och spännplattan 11 hålls samman medelst skruven 15 och de hålls i huvudsak parallellt med varandra och på ett avstånd från varandra motsvarande nogot mer än stödrullarnas 12, 13 axiella längd medelst skruvar 16, 17, som kan ha ett huvud vid den ena änden och en mutter, företrädesvis en vingmutter 18 vid den andra änden. Avståndet mellan L-stapeln 10A och spännplattan 11 bestäms i exemplet av en rörhylsformig bussning 19 på vardera skruven 16, 17, men i flertalet fall är det till- räckligt, att stödrullarna 12, 13 utformas med en axiellt något utskjutande krage kring sina lagerhål. Det skall påpekas, att bärarens 10 och spännplattans ll sammanhållning och fastspänning på en isolator, såsom strax kommer att .var beskrivas, sker medelst de på tämligen stort avstånd från varandra belägna skruvarna 16, 17, på vilka stödrullarna 13, 14 år lagrade, och den avsevärt nedanför skruvarnas 16, 17 plan belägna skruven 15 ger möjlighet till en synnerligen stabil fastspänning av topplinvagnen på respektive isolator.The vertical L-stack 10A of the carrier 10 and the clamping plate 11 are held together by means of the screw 15 and they are kept substantially parallel to each other and at a distance from each other corresponding slightly more than the axial length of the support rollers 12, 13 by means of screws 16, 17, which may have a head at one end and a nut, preferably a wing nut 18 at the other end. The distance between the L-stack 10A and the clamping plate 11 is determined in the example of a tubular sleeve-shaped bushing 19 on each screw 16, 17, but in most cases it is sufficient that the support rollers 12, 13 are formed with an axially slightly projecting collar around their bearing holes. It should be pointed out that the cohesion and clamping of the carrier 10 and the clamping plate 11 on an insulator, as will be described shortly, takes place by means of the screws 16, 17 located at a fairly large distance from each other, on which the support rollers 13, 14 are mounted, and the screw 15 located considerably below the plane of the screws 16, 17 provides the possibility of a particularly stable clamping of the top line trolley on the respective insulator.

Bärarens 10 vertikala L-stapel 10A. har en central, avlång öppning 20, vilken är utformad att gripa kring ett kantparti på en isolatorfläns, så att flänskanten skjuter något genom L-stapeln 10A. Spännplattan 11 är på motsvarande i» \_ F75 4 sätt försedd med en central, avláng öppning 21, vars form och ändamål svarar mot öppningens 20. Vidare har bärarens 10 vertikala L-stapel 10A vid sin övre kant en central, mjuk- linjigt avrundad utbockning 22, vilken är utformad att gripa runt och anligga mot ett halsparti på en isolator. En mot- svarande central, mjuklinjigt avrundad utbockning 23 är utformad vid spännplattans 11 övre kant.The vertical L-stack 10A of the carrier 10. has a central, elongate opening 20, which is designed to grip around an edge portion of an insulator flange, so that the flange edge projects slightly through the L-stack 10A. The clamping plate 11 is correspondingly provided in a manner with a central, elongate opening 21, the shape and purpose of which corresponds to that of the opening 20. Furthermore, the vertical L-stack 10A of the carrier 10 has at its upper edge a central, soft-line rounded bending 22, which is designed to grip around and abut against a neck portion of an insulator. A corresponding central, soft-lined rounded bend 23 is formed at the upper edge of the clamping plate 11.
