Definitions
- the invention relates to a surfacing device for substantially flatten the upper surface of a material viscous content in a container and a method of surfacing using such a device.
- surfacing refers to the operation of rendering the surface of a viscous material such as concrete or cement.
- a surfacing operation is performed manually with a tool with a flat surface (a ruler or a mason's trowel), this tool being moved horizontally and substantially parallel to the surface to be smoothed by the operator, the flat surface, for example the edge of the tool, penetrating a few millimeters inside the material to "level" the surface top of the viscous material to flatten it.
- the operator prints to the tool a movement, left to his discretion, which can be circular, linear or any.
- FR 2 693 399 relates to a device for ensuring the distribution, shaving and finishing of concrete poured by a hopper in molds mounted in the distribution module of a table vibrant.
- a mobile container which moves on rolling tracks according to a horizontal alternative translation movement, mechanical means for the distribution, shaving and finishing of the concrete during and after the introduction of this concrete into the molds.
- These mechanical means are realized in the form of a system of rotors or a worm system.
- SU 1 201 388 relates to a device for compacting concrete placed in a mold thanks to a pestle whose axis of rotation is shifted by a gamma angle to the axis of rotation of the shaft which carries it so as to obtain an eccentric rotation.
- the present invention aims to solve the disadvantages of the prior art by providing a device for to automate the surfacing operation to make this operation reproducible and achievable without the intervention of an operator near the container.
- the combination of the lift and rotation of the ruler, during the second phase makes it possible to achieve the surfacing by the passage in several times, and at heights steadily growing, rule in every spot on the surface upper viscous material so that when the rule is more in contact with the surface, all the material has been regularly distributed without the need to remove surplus material, and by the same to clean any splashes.
- the said subassembly further includes an arm attached to said lower portion of the shaft and extending diametrically above said opening in said operating position, an end portion of the arm being connected to said rule and the other end portion being connected to a system balancing device ensuring the horizontality of the longitudinal portion of the lower surface of said rule.
- said subassembly further comprises a vibratory system connected to said rule, in order to add a vertical oscillations movement to said rule during its rotation, and a damping system placed between said arm and said ruler and avoiding the transmission of vibrations resulting from oscillations of the rule to the rest of said device.
- said system vibratory includes a pneumatic vibrator integral with said rule and powered by a compressed air circuit comprising a source in compressed air, an angled feed tube having a section upstream, preferably vertical, connected to said source, a connection rotating connecting the downstream section of said tube to the upper part of said shaft, a longitudinal channel passing right through said shaft and a flexible tube connecting the lower end of said channel to said vibrator and said damping system has resilient studs.
- the second phase is a phase during which, at first, we activate said second motor means for rotating said rule according to a first speed of rotation then, in a second time, said second motor means is activated to rotate said rule at a second speed of rotation, less than first speed of rotation.
- the present invention also relates to the use of surfacing device of the aforementioned type for a container, of preferably made of concrete, which contains said viscous material, preferably concrete, and at least one container containing waste contaminated for subsequent long-term storage and that said viscous material has been poured into said container during the vibratory phase of a vibrating table with vertical acceleration on which container is retained.
- the illustrated embodiment relates to the use of the surfacing device which will be described hereinafter for a container used in the nuclear industry, to pack waste contaminated by coating in fiber concrete.
- the waste in question is first placed in specially designed cases specifically that are stacked inside a container or cylindrical container 12, preferably made of concrete itself fiber.
- the cases 10 are embedded within a mass of one highly viscous material 14, preferably of fiber concrete, which has been previously poured inside the container up to a level almost flush with the upper edge 12c of the container 12.
- the container 12 formed of a bottom wall 12a and a cylindrical side wall 12b, rests, by the lower face 12d of the bottom wall 12a, on a support whose flatness is at least Same level of quality as the 12d face.
- the upper level 14a thereof is located a few inches below the free edge annular upper 12c of the container 12.
- the concrete must have a state of perfect surface on its surface 14a to allow the superposition by stack of a series of containers 12 which ensures the absence of a any defect or damage to the concrete surface 14a when it is dry. Indeed such a defect would be likely to compromise the long-term tightness of the container 12, its storage being planned for several hundred years.
- the surface upper 14a of the concrete 14 which constitutes the upper surface of the container, no other lid is needed. So. if this upper surface 14a has unevenness or unevenness of surface area, these may lead to cracking, for example following an infiltration of liquid.
- pouring concrete 14 within the container 12 is carried out while the container 12 is subject to a vibrating table to prevent any air bubbles inside concrete. If, after filling, it is judged that a quantity of concrete excess is present in the container 12, it is expected that, previously to the surfacing operation, the container 12 goes to level of a scraping station that removes the excess concrete, that is to say, almost all the concrete that protrudes beyond the edge upper 12c of the container 12.
- FIG. 2 illustrating schematic the surfacing device 20 according to the present invention, placed in its operative position above the container 12.
- the surfacer 20 has an upper portion 20a corresponding to all the elements of motorization and guidance, advantageously controlled remotely, and which allow to realize simultaneously or successively a movement of vertical translation and a rotational movement as it will be described below.
- the lower part 20b of the device 20 comprises all the elements allowing the rule to be correctly positioned and to have the most appropriate movement to get, after surfacing, a state of the most plane surface possible, that is to say a upper surface 14a of the concrete as smooth as possible.
- the operating principle is as follows: a rule 22 is placed above the container 12 opposite a radius of its opening 12e, the rule having a length substantially equal to inner radius of the container 12 and having a specific profile which will described later. Rule 22 is rotated around the Z axis of the container 12 while the bottom surface of the ruler is located at a few millimeters below the surface 14a of the concrete so as to divide the amount of concrete above this level. According to principle of the present device, while the rule 22 is in rotation. it is lifted vertically gradually out completely concrete to obtain a plane surface 14a '. Of preferentially, the raising of the rule takes place in two time (roughing and finishing) corresponding respectively to two successively fast rotation speeds (working speed) and slow (finishing speed).
- the device 20 comprises a set of elements forming a set mobile in vertical translation, part of this mobile assembly 24 forming a subassembly 26 which is further rotatable,
- the device 20 further comprises a housing 28 having an open bottom portion, fixedly disposed substantially above the 12th opening of the container 12 in said operational position illustrated on the FIG. 2.
- this casing 28 is housed at least partially said mobile assembly 24 provided with a housing 30 movable in translation vertical to the housing 28 and housing the upper part of the subassembly 26.
- the housing 28 and the housing 30 form two elements hollow mechanically welded nested one in the other.
- the device comprises first motor means in the form of a stepping motor 32 mounted at the top of said housing 28 and having an output shaft 34 vertical whose free end 34a is threaded and cooperates with the part upper 30a of the housing 30 forming a nut.
- the housing 28 is extended in its lower part by a bell 36 which closes, covering it, the 12th opening of the container 12.
- This bell 36 thus constitutes the lower part of the housing forming a lid of the container 12, placed above the rule 22 and comprising a circular lower edge 36a connected to the side wall 12b, sealing means being placed between the lower edge 36a of this lower part 36 and said side wall 12.
- the lower edge 36a of the bell 36 has a diameter equal to that of the upper edge 12c of the container 12, the seal being provided by a flat annular crush seal 38 compressed between the edges facing the bell 36 and the container 12.
- centering wedges 40 ensure this function.
- a first guiding system ensures the movement of vertical translation between the casing 28 and the moving assembly 24 thanks to the presence of at least one bearing 42 placed between the inner surface of the housing 28 and the outer surface of the housing 30.
- the device 20 comprises two bearings 42 located respectively at the top and at the bottom of the upper part 20a of the device 20.
- a key 44 is mounted between them.
- the rotation of the threaded free end 34a of the shaft 34 causes the translation vertical housing 30 and all the elements it contains and which him are united.
- the upper portion 46a of the shaft 46 is connected to means for setting in rotation comprising second motor means, integral with the housing 30, which ensure, with a second guiding system, a rotational movement between said subassembly 26 and the housing 30, the shaft 46 being rotatably mounted in the housing 30.
- the second motor means comprise a set motor-reducer 48 consisting of a motor driving a gear reducer vertical axis speed which rotates a pinion axis 50 vertical.
- This pinion 50 meshes with a toothed wheel 52 coaxial with said shaft 46 and fixed around the upper portion 46a of this shaft 46.
- This toothed wheel 52 has a number of teeth which will have been determined in order to obtain the desired reduction ratio between the wheel 52 and pinion 50.
- a second guide system comprising at least one bearing 54 placed between said shaft 46 and said housing 30.
- two bearings 54 have been placed, preferably tapered roller bearings along the shaft 46. These bearings 54 prevent lateral movement of the shaft 46, and all the elements attached to it that form the subset 26, compared to housing 30.
- the device further comprises means for detecting the angular position of said subassembly 26 relative to the housing 30 through a coding ring 56 fixed on the wheel 52 and carrying, at two different heights, terminals regularly distributed over the circumference of the crown 56.
- Two inductive proximity sensors 58 are placed next to the crown 56 to possibly identify the passage of a terminal in look at one of the detectors 58. Terminals and detectors 58 form a logical whole allowing to know at any time the number of revolutions made by the shaft 46, that is to say by the rule 22.
- the lower part 46b of the shaft is connected to a horizontal arm 60, the shaft being centered on this arm 60.
- a first end portion 60a (left in FIG. 2) is connected, via a support system, to the rule 22 and the second end portion 60b of the arm 60 (part right of Figure 2) is connected to a balancing system under the form of a counterweight 62 for ensuring the horizontality of the arm 60 in order to also keep horizontal rule 22 without creating imbalance at the bottom of the shaft 46.
- the device 20 also comprises a pneumatic vibrator 64 for printing at rule 22 a movement of vertical oscillations during its rotation, these oscillations which considerably improve the state of final surface of the concrete 14.
- a pneumatic vibrator 64 for printing at rule 22 a movement of vertical oscillations during its rotation, these oscillations which considerably improve the state of final surface of the concrete 14.
- a compressed air circuit which arrives at the device 20 by a angled feed tube 66 having an upstream section 66a vertical, in fluid communication with an air source compressed, passing through the upper wall of the casing 28 so sliding and forming a pivot connection 68 with the upper wall of the housing 30.
- the downstream section 66b of the feed tube 66 is connected to a rotating coupling 70 coaxially placed above the part upper 46a of the shaft 46 which has a longitudinal channel 46c opening into the lower part 46b of the shaft 46 at a tube flexible 72 whose other end is connected to the vibrator 64.
- Rule 22 is fixed under an adjustable plate.74 which can slide against a fixed plate 75, placed above the plate 74, through a screw (not shown), the assembly forming means for adjusting the radial position of the ruler 22 relative to the shaft 46.
- the vibrator 64 is placed above the fixed plate 75 which is connected to the arm 60 by four elastic studs 76 forming a system of damping intended to attenuate the transmission of vibrations vibrator to the rest of the elements of the device 20.
- the lug 78 forms a depression at the upper surface 14a of the concrete, this depression being progressively filled by the concrete during the second phase of raising of said rule 22 so as to be able to use the residues accumulated in the center of the surface thus avoiding the formation of a central picot of material that would be unacceptable.
- the radially outer end 22b of the rule 22 is to it provided with a seal of elastomeric material 80 which extends radially the rule and which is intended to come into contact with the face internal sidewall 12b of the container 12 to prevent a material recovery at this level.
- Rule 22 has a horizontal longitudinal portion 22c delimited by a contour forming a section of a ring having an inner radius R2 and a ring width e. This horizontal portion 22c is adjacent to and delimited by a wall vertical posterior 22d.
- the horizontal portion 22c is extended towards the anterior wall 22e vertical, by an inclined portion 22f, ascending from the horizontal portion 22c towards the sidewall of the rule 22 forming the anterior wall 22e during the Rule 22.
- the front edge 22g of the inclined portion 22f forms an ascending line from the radially inner end 22a direction of the radially outer end 22b of the ruler, this edge 22g prior forming an arc of radius R1 projection horizontal (figure 4) and a straight line in projection. vertical ( Figure 3).
- the posterior edge 22h of the inclined portion 22f, adjacent at the horizontal portion 22c, forms an arc of radius of radius R2, R2 being larger than R1.
- Rule 22 has a polygonal cross section to five sides corresponding to a rectangle whose angle, between the wall front 22e and the horizontal wall 22c, is truncated to form the sloping portion 22f.
- the very particular profile of this Rule 22 is intended to homogenize the relative speeds of scrolling between the center 22a and the periphery 22b of the rule 22 with respect to the container 12.
