Definitions

  • a cutter suction dredger of this type is known from NL-A-671 1816.
  • a supporting plate which is adjustable by means of hydraulic piston/cylinder devices. By pressing the supporting plate against the bed, the cutter head can continue to follow the bed profile, even if swell occurs. During operation, the cutter head is moved back and forth over the bed, and moved forwards in steps after each swinging motion of the pontoon and the ladder. The supporting plate must here slide over the bed.
  • the spud pole no longer needs to be rigidly connected to the pontoon during the swinging motion. This enables the spud pole to be spring mounted, whereby it will be less heavily loaded. If it is desired to set the cutter head to a specific depth, the supporting device can preferably be suspended from the ladder such that it is vertically adjustable, for example by means of a piston/cylinder device.
  • the supporting device can be variously realized. According to a first option, it can be shaped as a foot (Fig. 5-6b). In that case, both the foot and the sliding member can be accommodated on a frame which is tiltably suspended from the ladder and which is drivable, for example, by a hydraulic piston/cylinder device. By tilting the frame into the desired position, either the foot can be supported on the bed, for stabilization of the cutter head in the swinging motion, or the sliding member can be supported on the bed, for displacement of the cutter head transversely to the swinging motion in the plane of the water bed.
  • the supporting device can be realized as a roller having a rotationally symmetric surface, the centre axis of which is directed horizontally and transversely with respect to the ladder, as well as a row of projections distributed evenly over the periphery of the roller, such as blades directed parallel to the centre axis of the roller (Figs. 9, 10).
  • Such blades allow the swinging motion, yet obstruct the forward movement.
  • a forward movement is made possible, however, by rotation of the roller, whereupon successive blades are pushed into the bed.
  • the roller can interact with a braking member in order to set a fixed rotation position of the roller.
  • the roller can interact with a drive mechanism to set the roller in rotation.
  • a connecting means of adjustable length can extend between the spud pole and the ladder.
  • connection to the spud pole may be located on a guide, for example a ring or a tubular member, which is led through the spud pole and can move in and/or around the spud pole and the height of which on the spud pole can be adjusted before and/or during the rotary movement of the cutter head by, for example, a piston-cylinder device located in or on the spud pole.
  • a guide for example a ring or a tubular member
  • Fig. 4a shows the orbital movement of a long surface wave on shallow water
  • Fig. 4b shows a definition diagram of the 6 main movements of a floating cutter suction dredger.
  • the spud pole 4 stands vertically in the water bed 24 with a certain penetration depth 26 and at the top stands in two guide rings 42, which are fastened to a spud carriage 9 with wheels 12 having axes 13, which spud carriage can be moved horizontally over a horizontal guide 1 1 by means of a piston/cylinder device 10.
  • spud pole 5 is lowered into the water bed 24, after which the spud pole 4 is hoisted and the spud carriage 9 with piston/cylinder device 10 is withdrawn again to the starting position.
  • the spud pole 4 is then lowered into the water bed 24 and the spud pole 5 is hoisted again. After this, the swinging motion is continued and at the end of the cut is advanced in the angle again by a step s.
  • a possible cut pattern is given by cuts A to H with step size s and cut height d.
  • Figs.6a and 7a are, as stated, side views of a possible embodiment of the supporting device, wherein the extreme position 55 represented with broken lines reveals that the supporting surface can be brought well below the cutter head. That this is of importance when the cutter head is lowered to the ground surface or raised from the ground surface is explained below.
  • the tilting arm 27 with support 52, wire 21 and/or projection 59 ensure a fixed position of the cutter head in the horizontal and vertical direction in the vertical plane through the longitudinal axis of the pontoon.
  • the bottom edge of the ladder rests with the supporting surface 52 on the ground surface.
  • the supporting surface 52 produces with the hoisting wire 6 the forces which are necessary for the torque equilibrium about the ladder hinge 20 with the forces resulting from the weight of the ladder and the forces of the cutting process and the tensioning force in the wire 21 and/or the projection 59.
  • the horizontal position of the supporting surface 52 is also fixed with respect to the ground surface 24.

Abstract

La présente invention se rapporte à une drague suceuse à couteau, ladite drague comprenant un ponton (1), une échelle (2) dont une extrémité est suspendue à partir du ponton, ladite échelle pouvant être amenée dans une position qui se dirige vers le bas par rapport au ponton, une tête de couteau (3) destinée à couper la roche ou le sol à l'autre extrémité de l'échelle, une unité d'extraction destinée à extraire de la roche ou du sol coupé, au moins un montant de forage (4) qui coopère avec le ponton pour ancrer le ponton par rapport à un lit (24) ainsi qu'un dispositif de support (49, 52, 53) agencé à proximité de la tête de couteau et destiné à supporter la tête de couteau par rapport au lit. De plus, des moyens de stabilisation (59, 65, 66) sont agencés pour stabiliser la tête de couteau (3) et/ou l'échelle (2) par rapport au plan, et le long de ce dernier, défini par le lit.
