Definitions

  • the present invention relates to a drilling bucket of the type including verticality correction systems.
  • the drilling rigs can be used in particular to carry out excavations with significant depth. It is especially but not exclusively the case when you want to make a wall molded in the ground. For this, we dig successively portions of trenches having the total depth desired, these trenches being subsequently filled with concrete to carry out the adjacent panels of the overall diaphragm wall.
  • An object of the present invention is to provide a drilling bucket fitted with verticality correction devices which allow such corrections with great precision whatever the nature, i.e. the sense, verticality defects.
  • At least one of said pads further includes an auxiliary vertical correction pad capable of projecting outside the central face of the skate and means for moving the upper end and the lower end of said auxiliary shoe relative to said shoe according to a direction orthogonal to said pivot axes.
  • the body of the bucket 22 has a vertical axis in conditions of normal operation Z-Z '.
  • Z-Z ' To locate the position of the bucket assembly relative to the space, to this one can associate the vertical axes Z-Z ', an axis X-X 'parallel to the pivot axes x-x' and y-y 'and an axis Y-Y' in the plane of Figure 1, this axis Y-Y 'being orthogonal to the axes x-x' and y-y '.
  • the axis X-X ' identifies the thickness of the bucket and the axis Y-Y' identifies its width.
  • the body of the bucket 22 is equipped two position correction pads 32 and 34 which are mounted movable by relative to the chassis 24 of the body of the bucket as will be explained later.
  • the pads 32 and 34 are actually in contact with the wall of the trench during digging and that by changing the position of the body of bucket compared to these two skids, we can actually correct the vertical defect in the bucket making the trench.
  • FIG. 2a we have schematically represented the chassis 24 of the body of the bucket which has two vertical main faces 36 and 38 which are arranged in planes Y-Z and two lateral faces 40 and 42 which are arranged in X-Z planes.
  • the outskirts of main faces 36 and 38 and the side faces 40 and 42 are covered by correction pads 32 and 34 respectively.
  • each pad 32 or 34 has a U shape.
  • each pad has two wings 44 and 46 arranged opposite the periphery of the main faces 36 and 38 and a portion central 48 which connects these two wings and which is opposite the lateral faces 40 and 42 of chassis 24.
  • Each shoe 32 and 34 is equipped with two displacement devices in the direction X-X 'arranged respectively at the upper end and at the lower end of the skate. These displacement devices are shown schematically in Figures 2a and 2b and are referenced 50 and 52.
  • the shoe 34 is of course also equipped with two displacement devices respectively upper and lower. As will be explained later in more detail, each displacement device 50 or 52 can be ordered separately.
  • the relative displacements of the chassis 24 relative to the pads 32 and 34 allow to correct at the upper and lower part of the body of grab the verticality errors with respect to the X, Y and Z axes.
  • At least one of the two pads is equipped with an auxiliary pad 56 which can be moved relative to the pad 32 itself in the Y direction. More specifically, the auxiliary shoe 56 is itself equipped with two displacement 58 and 60, respectively upper and lower. It is thus possible, by controlling the devices 58 and 60, to move the auxiliary shoe 56 by compared to shoe 32 in the Y-Z plane.
  • FIG. 4a shows a preferred embodiment of the upper device 50 for moving the shoe 32 relative to the chassis 24 of the grab.
  • the displacement device 50 in the direction X-X ' is essentially constituted by a guide and mechanical securing shaft 60 and by a displacement cylinder 62.
  • the guide shaft 60 has its two ends 60a and 60b which are rigidly fixed on the wings 44 and 46 of the shoe 32.
  • the shaft 60 is slidably engaged in a socket 63 which is connected to the chassis of the body bucket by a pivot axis 64 arranged in the direction Y-Y '.
  • Cylinder 62 which is preferably double acting allowing to define three positions to its body 66 which is integral with the chassis of the body of the bucket.
  • the rod 68 of the jack 62 has its free end which is pivotally connected by a pin 70 engaged in the wing 44 of the skate.
  • the rod 68 of the jack can therefore move in the direction XX '.
  • the rod 68 can take a neutral position shown in Figure 4a in which the wings 44 and 46 of the skate are symmetrical with respect to the body of the body. We do not induce any verticality correction at the top of the skate.
  • the stem can take a fully retracted position as shown in Figure 4b. As shows this figure, it causes a tilt to the left with respect to the axis Z-Z 'of the skate. It can finally take a fully extended position.
  • FIG. 5a and 5b we will describe a mode preferred embodiment of the lower displacement device 52.
  • This device is still constituted by a jack 71 with three positions whose body 72 is integral with the frame 24 of the body of the bucket and whose free end of the rod 74 is mounted at pivoting on the wing 44 of the shoe 32.
  • the displacement device 52 comprises also a guide shaft 76 which is slidably mounted in a bushing 78 rigidly secured to the chassis of the body of the bucket. Shaft 76 is mounted sliding in the direction XX 'and is parallel to the axis of the rod 74 of the jack.
  • the ends 76a and 76b of the shaft 76 are engaged in oblong holes 80 and 82 formed in the wings 44 and 46 of the shoe 32. Shoulders 84 and 86 formed at the ends of the shaft 76 allow the useful mechanical connection between this tree and the wings of the skate while authorizing the degree of freedom necessary in the direction Z-Z '.
  • FIG. 5a the jack 71 is shown in its neutral position and the wings of the skate are therefore symmetrical with respect to the chassis of the body of the bucket.
  • FIG. 5b the jack is shown in its entirely position outlet, which gives the shoe 32 an inclination relative to the axis Z-Z '.
  • cylinders 62 and 71 of pads 32 and 34 displacement devices can be ordered independently. We understand that in this way it is possible to communicate to these two skids of relative displacements relative to the chassis of the body of skip allowing all verticality defect corrections except verticality defects in the Y-Z plane.
  • auxiliary shoe 56 which is connected to the displacement devices upper and lower respectively of the shoe 32 by means of two rod systems visible in Figure 3. These rods were respectively referenced 84 and 86.
  • the links are articulated at a first end on the displacement device 50 and 52 and at a second end on the shoe 56.
  • the upper link 84 constitutes a device for upper displacement of the shoe auxiliary while the lower link 86 constitutes the displacement device inferior.
  • a cylinder is provided to control the movements of the shoe 56.
  • control 88 whose free end of the rod 90 is articulated at the end of the lower link 86 and whose body 92 is pivotally mounted relative to the main skate movement device. This constitutes a deformable parallelogram.
  • the auxiliary shoe 56 therefore makes it possible to correct the vertical defects in the Y-Z plane by translational displacement according to the Y direction of the auxiliary shoe.
  • FIGS. 6 a to 6 c illustrate the corrections that can be made thanks to the displacement devices 50 and 52. It is understood that if one acts in the same way on the devices 50 and 52 of the same pad, one obtains a translational effect on this side of the body. On the contrary, if the two devices are controlled differently, one obtains an inclination with respect to the "vertical" plane YZ.
  • FIG. 7a shows the auxiliary shoe 56 at rest, which does not produce no correction.
  • FIG. 7b shows an auxiliary shoe 56 in the extended position, which causes a translation of the body of the bucket in the direction Y-Y '.
  • each device for displacement of the pads 50, 52 comprises an axis 60, 76 integral with at least one wings 44, 46 of a shoe and arranged parallel to said pivot axes between said wings, a sleeve 63, 78 in which is slidably engaged said axis, said sleeve being integral with chassis 24 of said bucket and a cylinder 62, 71 whose body 66, 72 is integral with the chassis and whose rod 68, 74 is moves parallel to said axis, the free end of said rod being integral with a said wings.
  • the socket 63 of the upper displacement device 50 is made integral with the chassis by through a joint whose axis is parallel to the vertical axis of the chassis.
