Description
Vorrichtung zuni Spreizen der Reißklauen Zusatz zum Zusatzpatent 449 953 Die Erfindung bildet einen Zusatz zum Zusatzpatent 449953. Mit dieser Vorrichtung wird eine hinterschneidende Erweiterung des Bohrloches von außen her erreicht, die das Spreizen und wirkungsvollere Eingreifen der Reißklauen im Gestein bewirkt.Device for spreading the ripping claws Addendum to additional patent 449 953 The invention is an addition to the additional patent 449953. With this device an undercut enlargement of the borehole is achieved from the outside, which causes the ripping claws to spread and more effectively intervene in the rock.
Die Vorrichtung ist in der Zeichnung dargestellt Abb. i zeigt den Druckkegel e mit Knaggen L, die während der Spreizbewegung zwischen je zwei Reißklauen treten, auf diese als Mitnehmer wirken und sie bei Drehung der Vorrichtung mit in Umdrehung versetzen.The device is shown in the drawing Fig. I shows the Pressure cone e with lugs L, which during the spreading movement between two ripping claws step, act on this as a driver and when rotating the device with in Offset rotation.
Abb. a stellt den Zerreißer im Bohrloch lt mit zum Teil gespreizten Reißklauen d in der durch ihre Drehbewegung bewirkten Bohrlocherweiterung im Gestein i dar.Fig. A shows the ripper in the borehole lt with partially spread Ripping claws d in the borehole enlargement caused by their rotary motion in the rock i represent.
Der Vorgang ist folgender: Der Kegel p besitzt kein Gewinde, sondern ist mit dem Rohrfund dem Handrad q starr verbunden über die Spindela so geschoben, daß die Knaggen L zwischen die Klauend treten. In dieser Lage werden die genannten drei Teile in bekannter Weise mittels einer Klemmvorrichtung, die außen hinter dem Handrad sitzen kann, an der Spindel a nach Bedarf festgeklemmt oder gelöst. Im gelösten Zustand läßt sich der Kegel in Verbindung mit dem Rohr und dem Handrad auf de'r Achsea verschieben, wobei die Spreizung der Klauen durch Vorschieben oder Zurücknehmen des Kegels regulierbar wird. Die Klauen lassen sich mittels des Handrades q von außen her sowohl im gelösten, wie auch im mit Spindel a verbundenen Zustand in Umdrehung versetzen, wodurch die .erweiternde Hinterschneidung des Bohrloches erreicht wird.The process is as follows: The cone p has no thread, but rather the handwheel q is rigidly connected to the pipe find and pushed over the spindle so that that the lugs L step between the claws. In this situation the mentioned three parts in a known manner by means of a clamping device, the outside behind the Handwheel can sit, clamped or loosened on the spindle a as required. Im solved State can be the cone in connection with the tube and the handwheel on de'r Achsea move, with the spreading of the claws by advancing or withdrawing of the cone is adjustable. The claws can be moved from externally both in the released state as well as in the state connected to spindle a in rotation move, whereby the .Expanding undercut of the drill hole is achieved.
