Spannorganet 8 bestar av en mot andpartiets 4 tungor 7 anpressbar, konisk kropp 9, som Or fast vid en stang 10, vilken stracker sig genom en kanal 11 i den cylindriska delen och med sin fria ande 12 utskjuter ur derma del. Anden 12 Or forsedd med ett gangat parti, pa vilket Or ,anbragt en till ett anslag 13 pa den motsvarande anden av den cylindriska. delen 1 inskruvbar mutter 14. For att forhindra vridning av anordningen vid fastspanning av denna pa roret Or den med anslaget 13 forsedda anden av den cylindriska delen utformad med ett for en skruvnyckel avsett, mutterliknande parti 15. The device shown in the drawing consists of a guide member 1, which is made of a cylindrical part, which has an externally threaded portion 2 with substantially the same diameter as a tube 3, to which the device is intended to be fastened, and of a duct portion 4 with slightly smaller outer diameter depends on the inner diameter of the rudder. The gangway portion 2, the gangways of which have the same pitch as the ungulates on the slopes of a standard gangway intended for gangling the pipe 3, or are intended to receive and guide the gangway tool during the intersection of a gangway. In the duck party 4 Or made a borehole 5, varjamte it on so. is provided with a sleeve or a tube-shaped duct portion 4 Or provided with axial slots 6 for healing a number of tongues 7 serving for tensioning means 7, which are arranged to be brought into non-rotatable engagement with the forefoot 3. by means of another tongue squeezing means 8. of a conical body 9 which can be pressed against the tongues 7 of the duck portion 4, which Or is fixed to a rod 10, which extends through a channel 11 in the cylindrical part and with its free spirit 12 protrudes from this part. The spirit 12 Or is provided with a stepped portion, on which Or, one is applied to a stop 13 on the corresponding spirit of the cylindrical one. screw screw-in nut 14 to prevent rotation of the device when clamping this tube.

Anordningen anvandes pa fOljande salt: Det hylsformiga andpartiet 4 infores i rorets 3 and, varefter muttern 14 atdrages mot anslaget 13. Yid atdragningen av muttern forskjutes stAngen 10 axiellt utat, varvid den vid stangen fdst-a koniska kroppen 9 med sin koniska yta pressar tungorna 7 till anliggning mot rorets insida. Sedan ,anordningen fastspants Add roret bringas en passande gangkloppa till ingrepp med det gangade partiet 2, varefter gangkloppan kringvrides tills den in-griper med r6randen, i vilken gangkloppan under den fortsatta kringvridningen skar en gdnga. Harigenom erhaller gangkloppan en saker och ,effektiv •styrning vid ingreppet med roret och under skarningen av en sa lang ganga, att ga-ngkloppan vid fortsatt skarning styres av denna. Genom den ovannamnda styrningen mojlig,gores, ocksa anvandningen av gangverktyg, som icke hava .armar och som kunna kringvridas medelst en hylsnyckel eller liknande, om roranden Or synnerligen svaralkomlig. The device is used on the following salt: The sleeve-shaped duct portion 4 is inserted into the duct of the tube 3, after which the nut 14 is tightened against the stop 13. When the nut is tightened, the rod 10 is displaced axially outwards, whereby the conical body 9 with its conical surface presses the tongues 7 for abutment against the inside of the rudder. Then, the device is clamped to the pipe, a suitable gangway is brought into engagement with the gangway portion 2, after which the gangway is rotated until it engages with the pipe edge, in which the gangway during the further rotation cuts a passage. In this way the gangway obtains a thing and, effective • control at the engagement with the rudder and during the intersection of such a long gangway that the gangway door is controlled by it when it is continued. The above-mentioned control also makes it possible to use walking tools which do not have arms and which can be rotated by means of a socket wrench or the like, if the rudder edge is particularly responsive.

En anordning enligt uppfinningen anvandes namligen i stor utstrackning vid reparation av ledningar for att rensa upp gamla gangor. Det Or harvid av betydelse att gangorna pa det gangforsedda styrorganet kunna installas eller vridas sa, att de komma i exakt ratt lage i forhallande till gangorna pa roret, varigenom gangkloppan styres in i de senare. Denna installning mojliggores pa ett effektivt satt med tillhjalp av partiet 15, som Or utformat till en mutter, vilken vid kringvridning medelst skruvnyckeln bringar gangorna pa det gangforsedda styrorganet att noggrant Overensstamma med gangorna pa roret. 2— — En annan fordel med anordningen "enligt uppfinningen är den, att gangkloppan kan anbringas pa styrorganet eller installningen av anordningen, sã att man latt kan se att installa gangorna pa styrorganet och roranden, vilka gangor hava sanuna stigning, i exakt lage mitt far varandra. A special advantage of the invention The device can be installed in different types of rotation. Namely, a device according to the invention was used to a large extent in the repair of pipes for cleaning up old corridors. It is important that the aisles on the aisle-guided guide member can be installed or rotated so that they come into exactly the right position in relation to the aisles on the pipe, whereby the aisle bell is guided into the latter. This installation is made possible in an efficient manner by means of the portion 15, which is formed into a nut, which, when turned by means of the wrench, causes the passages on the actuated guide member to accurately conform to the passages on the pipe. Another advantage of the device "according to the invention is that the gangway can be mounted on the guide member or the installation of the device, so that it can be easily seen to install the aisles on the guide member and the rudder edge, which aisles have the same pitch, in exactly the same position. each other.
