Definitions

  • the present invention is in the general field of building and construction, particularly in the cutting of material and the sawing of a surface such as a floor slab.
  • the invention will find a specific application in the cutting of a floor slab made of hard material, such as concrete.
  • the object of the invention is to provide a rectilinear groove through such a floor slab.
  • such a groove may notably and preferably be intended to receive drive means, such as a chain, a cable or any other means of traction or mechanical guidance, an automatic scraper, for cleaning the surface of said slab or guide a food dispenser for example.
  • drive means such as a chain, a cable or any other means of traction or mechanical guidance, an automatic scraper, for cleaning the surface of said slab or guide a food dispenser for example.
  • Such a groove may also receive electrical cables.
  • said groove must have dimensions (width and depth) allowing said drive means to be placed internally therein, with a very low degree of freedom and with a particularly reduced clearance for, on the one hand, being able to move freely and without restraint and, secondly, prevent any engagement or penetration of an object or limb, including a leg of an animal that could be injured or whose hooves would risk to be damaged.
  • This groove must, therefore, have particularly precise dimensions (to the millimeter) and a perfect surface condition (clean cut and free of asperities), both on the sides and in the bottom of this groove.
  • a cutting and sawing device of this groove must therefore make it possible to adapt its dimensions, namely width and depth, of each cut.
  • Such a device is described in the document DE 4206643 and relates to the production of grooves on an asphalt or concrete floor slab.
  • Such a device is therefore in the form of a carriage-type vehicle provided with two parallel rolling axles, for its movement, at least one of which is motorized. This vehicle receives cutting tools in the form of circular saws rotated in the front portion, upstream of the rolling means, and on one side of the machine.
  • the frontal tool comprises two saws, diamond-type disc, one fixed is aligned with the saw, also fixed, lying on the side.
  • An additional front saw is slidably mounted transversely along the same axis as the fixed front saw. This mobile saw allows to perform a second bleeding parallel to those performed by fixed saws.
  • all saws are movable vertically, so as to move from a high retracted position to a low cutting position, and vice versa.
  • Such a device comprises two pairs of tools, each in form of two circular saws, located at the front and on each side of the vehicle, always upstream of the rolling means.
  • the spacing of the front saws makes it possible to make two grooves of small width, but associated with the side saws, they make it possible to perform simultaneously four grooves with the same spacing.
  • the devices of the state of the art all include cutting tools to make bleeding. It is then necessary to involve other tools for excavating the remaining material between these grooves, in particular to form a groove.
  • the invention aims to overcome the drawbacks of the state of the art by providing a slab cutting device so as to provide a groove.
  • such a device is in the form of a vehicle equipped with at least two rolling axles, said device comprising cutting means movably mounted so as to move from a retracted high position to a low position of cutting, and vice versa, characterized in that said cutting means comprise, on the one hand, on one side of said vehicle at least two circular saws rotated along the same axis, so as to simultaneously provide two parallel grooves, and, on the other hand, at least one cutter rotated downstream of said saws, so as to hollow out the material between the two grooves, thereby providing a groove.
  • the present invention relates to surface cutting, in particular the production of a groove within a floor slab.
  • Such a slab is made of a hard material, very resistant, concrete type, stone or the like.
  • the invention relates to a floor slab cutter, which is in the form of a vehicle 1.
  • Such a vehicle is equipped with at least two axles 2 and 3 of rolling. Both axles 2,3 are motorized so as to allow the vehicle 1 to move on said slab.
  • the front axle 2 provided for the drive of the vehicle, the rear axle 3 is director and motor.
  • the steering rear axle 3 can advantageously be in the form of a diabolo.
  • the rear axle 3 comprises two contiguous wheels 4 mounted on the same axis of driving rotation B-B ', in the rear central part of the vehicle. As visible by the arrows represented on the figure 2 this rear axle 3 is also mounted in vertical rotation so as to change the orientation of the wheels, thus directing the vehicle 1.
  • This configuration of the diabolo-shaped rear axle 3 makes it possible to control and modify the trajectory of the vehicle quickly and accurately. vehicle 1, and thus control the linearity of the cut made.
  • said device comprises cutting means movably mounted so as to pass from a high position. retracted to a low cutting position, and vice versa.
  • This mobility can be carried out for all or part of the means, independently of each other.
  • the means can thus be partly mounted in vertical translation, but also in pivoting for another part. This mobility offers a very precise adjustment of the positioning of the tools and the resulting cut.
  • said cutting means comprise, on the one hand, on one side of said vehicle 1 at least two circular saws 5 and 6 rotated along the same axis A-A '. These two saws 5 and 6 make it possible to simultaneously provide two parallel grooves 50 and 60. Said saw 5 is located at the outer end of said axis A-A ', while the saw 6 is located between the saw 5 and the vehicle 1.
  • the device also comprises at least a third circular saw (not shown), positioned between the two other saws (5; 6), and driven in rotation along the same axis (A-A ') that these two other saws (5; 6), this to simultaneously provide at least three parallel grooves (50; 60).
  • the presence of at least one such third circular saw advantageously makes it possible, in very hard soils, to reduce the vibrations of excavation of the milling cutter 9 (vibrations that are particularly detrimental to the proper operation, to the strength and to the life span of the circular saws, more particularly when they are made of diamond) and to limit the disturbances of the precise and fast cutting provided by the two other saws (5; 6).
  • said saws 5.6 consist of cutting disc with a hardness and thickness adapted to the material of the slab to be sawed.
  • these discs can be diamond type.
  • said cutting means comprise at least one mill 7 rotated downstream of said saws 5 and 6, so as to hollow out the material between the two grooves 50 and 60, thereby providing a groove 8.
  • said cutter 7 comprises planing lugs 9 mounted on a carrier disk 10 driven.
  • These lugs 9 are conically shaped, fixed at their base on said disk 10. They receive at their free end of an abrasive tool capable of allowing excavation, including a tungsten carbide type tool or the like.
  • said lugs 9 are arranged projecting from the periphery of the support disk 10, oriented obliquely in the opposite direction of rotation of the milling cutter 9, so as to penetrate the surface of the material situated between the two grooves 50 and 60. , the lugs 10 may be aligned or positioned staggered.
  • Another advantageous characteristic of the invention resides in the alignment of the saws 5, 6 and the cutter 9. Indeed, the latter can be strictly parallel. In other words, the planes containing the discs of the saws and the plane containing the support disc 10 are parallel to each other, thus optimizing the quality of the cut made.
  • said saws 5, 6 can be vertically movable, together or not, while the cutter 9 is pivotally mounted or also in vertical translation. This mobility makes it possible to adapt the cutting depth.
  • the spacing (spacing) between said saws 5,6 may be adjustable to adjust the width between the grooves 50 and 60.
  • the device comprises means for positioning the saws (5, 6) at different distances from one (5; 6) to the other (6; 5), for the realization of grooves (50, 60 ) spaced apart differently (50; 60) from each other (60; 50).
  • These positioning means are designed to make grooves (50, 60) spaced apart by a particularly precise distance (with a precision of the order of a millimeter) and corresponding (in a manner adjusted to the millimeter) to the dimensions of the means of training that should be arrange inside the groove 8.
  • such means for positioning the saws (5, 6) are constituted by sleeves (more particularly by a set of a plurality of sleeves) of different lengths (adapted to position a saw 6 at a determined distance d a further saw 5), extending along the axis (A-A '), fitted on an axle shaft (A-A') on which the saws (5, 6) are mounted, and interposed between these saws (5, 6).
  • These sleeves are interchangeable type and have a maximum length of 120mm.
  • the device comprises cutters 9 (more particularly a set of a plurality of cutters 9) whose dimensions (more particularly the width) are adapted to the different distances between the saws (5; 6). These burs 9 are preferably of interchangeable type.
  • Another feature of the invention is that the important thing is that the cutter 9 is very slightly behind the saws 5 and 6 to have a flawless cut left by these saws (5; 6) diamond.
  • the device comprises means for mounting the cutting means (saws 5, 6 and cutter 9), this movably between a retracted high position and a low cutting position, and vice versa, this as mentioned above.
  • these means for movably mounting the cutting means are constituted by means for mounting in vertical translation (along a vertical axis) and / or pivoting (along a horizontal axis) of these cutting means (saws 5, 6 and strawberry 9).
  • this device comprises means for adjusting the position of these cutting means (saws 5, 6 and milling cutter 9) to adjust the depth of the groove 8.
  • such a setting means is associated with said means for mounting the cutting means (saws 5, 6 and cutter 9), this movably between a retracted high position and a low cutting position, and vice versa, such that above.
  • the cutting means in particular the saws 5 and 6, are lubricated.
  • This lubrication makes it possible, in particular, to cool the tools but also to facilitate cutting.
  • this lubrication is performed by spraying a fluid, such as water.
  • At least one of said axles is located between said saws 5.6 and said cutter 9. This particular positioning makes it possible to minimize the vibrations generated by the tools.
  • said front axle 2 can be located between said saws 5.6 and said cutter 9.
  • the axle 2 acts as a buffer between the two tools, improving the sharpness of the cut made.
  • the cutting device according to the invention comprises means 11 for controlling the alignment.
  • these means 11 make it possible to check the rectilinear aspect of the tracing of the grooves (50, 60) and, therefore, of the groove (8), giving the operator the possibility of visualizing the variations, however small, in the axis of movement of the vehicle 1, and compensate quickly, especially through the axle 3 rear directional diabolo.
  • said control means are in the form of a rod 12 connected frontally and extending horizontally in front of the vehicle 1.
  • This rod 12 can be pivotally mounted pivotally at the front of the chassis so as to be reassembled in a vertical storage position.
  • this rod 12 is slidably mounted on the side of the vehicle 1, in a telescopic manner, thus making it possible to control the linearity of the displacement of the vehicle 1, even when approaching an obstacle or an obstacle.
  • the attachment means 13 of the rod 12 in the sliding position are visible on the figure 1 and are in the form of square section ring for receiving, free translation, a rod of the same shape.
  • the present invention provides a cutting device allowing in a single pass, the realization of the grooves and the excavation of the material located between, so as to form a groove 8 in a single operation.
