Definitions

  • the present invention relates to an apparatus for digging deep trenches in the ground using milling drums.
  • milling drums are rotated in opposite directions to break up the ground and dig the trench while the chassis is sinking into the ground.
  • Devices of this type can dig trenches whose depth is generally of the order of a few tens of meters but which can reach up to about 150 meters.
  • the positioning of the drums is mainly ensured by the chassis, the thickness of which corresponds to the width of the trench already executed and against which it bears.
  • the subject of the present invention is an apparatus for making deep trenches of the type in the ground comprising a chassis provided with milling drums at its lower part, characterized in that the chassis is provided at its upper part with at least a guide stop which is capable of being moved between an upwardly deployed position where it increases the effective length of the chassis during operation of the device and a retracted position down where it reduces the size of the chassis during transport of the device.
  • Each guide stop is telescopically mounted so that it can be placed in the high position or in the low position.
  • each guide stop is supported by a tubular piece which slides in an orifice of corresponding shape made in the body of the chassis, while a hydraulic cylinder fixed on the one hand to the chassis and on the other hand to the tubular part is housed inside the latter.
  • the movable guide stop is constituted by an element having substantially the same thickness as the chassis and extending substantially to each of the lateral ends of the latter, this stop being connected to the chassis by telescopic elements which allow it to be raised during operation and lowered during transport of the device.
  • the central part of the element constituting the guide stop comprises at least one orifice for the passage of the various flexible pipes which allow the energy required to operate the milling drums and to reassemble the cuttings to be brought in.
  • the displacement of the guide stop can be achieved by one or more hydraulic cylinders or by electrical devices incorporated in the chassis.
  • the retractable guide stops according to the invention are capable of correctly playing their role so that the apparatus behaves as a device comprising a chassis of greater height.
  • a metal frame 1 has substantially the shape of a rectangular parallelepiped, hollowed out in its central part 2 to receive the various members necessary for its operation.
  • a flexible pipe allows reassembly of the cuttings, and flexible pipes, not shown, supply the chassis with energy.
  • this pipe and these pipes pass through an orifice 3 formed in the upper part of the chassis 1, to lead into the central recess 2.
  • chassis 1 is capable of receiving at its lower part two milling drums, not shown, which make it possible to make the trench.
  • the frame 1 is provided with two guide stops 4 at its upper part, each one being mounted telescopically at the upper lateral end of the frame.
  • fixed pads 5 cover the outer faces of each stop 4 which are in contact with the walls of the trench during the excavation operation, so as to facilitate the sliding of the stops in the trench when the chassis is lowered.
  • Pads 5 'of the same type are secured to the lower part of each of the two large faces of the chassis, to facilitate its movement in the trench.
  • each shoe 5.5 ′ is extended lower and higher by a chamfer 5a which is intended to limit the risks of anchoring the chassis in the trench.
  • each stop 4 has the same thickness as the chassis 1, so as to bear on the walls of the trench in order to be able to guide the chassis.
  • each stop is supported by a tubular part 6 which is capable of sliding in an orifice 7 of corresponding shape provided in the body of the chassis.
  • a hydraulic cylinder not shown, is housed inside each tubular part 6, and ensures the displacement of each stop 4, while being secured on the one hand to the frame 1 and on the other hand to said tubular part 6.
  • a U-shaped section slide is secured to the stopper 4 and can slide between two flanges 9 of the frame which s 'extend over the entire height of its lateral end.
  • the device according to the invention has an effective length which varies depending on whether the guide stops 4 are placed in the high position or in the low position.

Gerät zum Ausheben tiefer Gräben im Gelände, bestehend aus einem Gestell, an dessen unterem Teil Frästrommeln angebracht werden, dadurch gekennzeichnet, daß das Gestell (1) im oberen Teil mit mindestens einem Führungsanschlag (4) ausgestattet ist, der sich zwischen einer nach oben ausgefahrenen Position und einer nach unten eingefahrenen Position verschieben läßt, wobei in der ausgefahrenen Position die wirksame Arbeitslänge des Gestells (1) während des Einsatzes des Gerätes vergrößert wird und in der eingefahrenen Position die Abmessungen des Gestells (1) für den Transport verkleinert werden.
  2. Gerät nach Anspruch 1, dadurch gekennzeichnet, daß die beiden Führungsanschläge (4) jeweils das gleiche Dickenmaß wie das Gestell (1) haben und sich an den äußeren Seitenkanten des besagten Gestells (1) befinden.
  3. Gerät nach Anspruch 2, dadurch gekennzeichnet, daß sich jeder Führungsanschlag (4) auf einem Rohrstück (6) befindet, das sich in einer Öffnung (7) bewegt, die in ihrer Form dem Rohrquerschnitt angepaßt und in der Gestellkonstruktion (1) ausgeführt ist. Ein Hydraulikzylinder im Inneren des Führungsrohres (6) ist mit seinem einen Ende am Gestell (1) und mit seinem Kolbenende am Führungsrohr (6) befestigt.
  4. Gerät nach Anspruch 3, dadurch gekennzeichnet, daß es weiterhin aus einer Gleitschiene (8) besteht, die mit jedem der Führungsanschläge (4) verbunden ist, in einer vorteilhaften Ausgestaltung einen U-förmigen Querschnitt aufweist und sich zwischen den beiden fest mit dem Gestell (1) verbundenen Flanschen (9) auf- und abwärts bewegt.
  5. Gerät nach Anspruch 1, dadurch gekennzeichnet, daß es aus einem Führungsanschlag besteht, der wiederum durch ein Element gebildet wird, welches das gleiche Dickenmaß wie das Gestell hat und bis zu den Außenseiten dieses besagten Gestells verläuft, und wobei das besagte Element im mittleren Teil mit mindestens einer Öffnung zur Durchführung von Schlauchleitungen und Kabeln versehen ist.
