Definitions
- the present invention relates to a self-propelled machine for concreting ditches, of the type comprising a propulsion unit driving means for moving the machine and a system for spreading a layer of concrete on the bottom and on the edges of the ditch as and as the machine advances.
- Machines of the aforementioned type have been designed for automatically concreting such ditches.
- These self-propelled machines span the ditch and have means of movement, such as wheels or tracks, which bear and roll on either side of the ditch.
- the importance of these development works varies according to the nature and the slope of the land. In general, these machines are very operational in flat or gently sloping terrain and sufficiently clear, but their use is made practically impossible in steep terrain and difficult to access.
- these machines were especially designed for carrying out large-scale works, in particular for the concreting of wide and deep ditches.
- the object of the invention lies in the production of a self-propelled machine which is particularly suitable for the concreting of small ditches of small width, and which is usable in hilly terrain and possibly difficult to access.
- the invention provides a machine for concreting ditches which is characterized by the fact that its means of movement bear and roll on the bottom of the ditch.
- the means for moving the machine consist of at least one track which advances on the bottom of the pit.
- the spreading system located towards the rear of the machine, is pulled by the track, in particular by resting on the layer of concrete which has just been deposited at the rear of the machine.
- the spreading system essentially comprises a concrete storage hopper, an endless screw in the bottom of the hopper for conveying the concrete in a formwork conforming to the shape of the ditch, this formwork comprising a lower opening facing the bottom of the pit and by which the concrete falls by gravity to form the bottom concrete layer, this lower opening being extended by two lateral openings located opposite the edges of the ditch and through which the concrete is sprayed, by means of fins driven in rotation by the auger, to form the lateral concrete layers.
- the spreading system is completed by compression means, such as a trapezoidal section plate which simultaneously compresses the layers of concrete deposited on the bottom and on the edges of the ditch, this plate serving also a support surface for the spreading system during the advance of the machine.
- compression means such as a trapezoidal section plate which simultaneously compresses the layers of concrete deposited on the bottom and on the edges of the ditch, this plate serving also a support surface for the spreading system during the advance of the machine.
- the machine bearing only on the bottom of the ditch, makes it possible to do away with all the development work around the pit, which until then had been necessary for moving the previous machines. It is thus possible to reduce the time and cost of making a concrete ditch.
- the machine guided by the track can follow any route, in particular with a steep slope and in rough terrain.
- the machine is compact and of small dimensions, which facilitates its transport to the sites of use.
- FIG. 1 is a schematic perspective view of the machine according to the invention
- FIG. 2 is a simplified longitudinal section view of the machine according to the invention
- FIG. 3 is a simplified view of the formwork of the concrete spreading system
- FIG. 4 is a schematic view of the principle of adjusting the thickness of the layer of concrete deposited
- FIG. 5 is a simplified view of the rear of the machine to show the means of compression of the concrete layers deposited in the ditch.
- the machine 1 according to the invention is shown in its working position inside a ditch F with trapezoidal section, having a substantially flat bottom FF and two inclined side edges BF.
- the double arrow F1 indicates the part of the ditch already concreted at the rear of the machine 1
- the double arrow F2 indicates the part of the ditch being concreted by the machine 1
- the double arrow F3 indicates the part ditch not yet concreted at the front of the machine 1.
- the machine 1 comprises a propulsion group 2 associated with displacement means 3 such as a track which is supported and rolls on the bottom FF of the ditch F, a spreading system 4 concrete, a compression and smoothing system 5 of the layers of concrete deposited in the bottom and on the edges of the ditch F, and a cockpit and control 6.
- displacement means 3 such as a track which is supported and rolls on the bottom FF of the ditch F
- spreading system 4 concrete such as a track which is supported and rolls on the bottom FF of the ditch F
- a compression and smoothing system 5 of the layers of concrete deposited in the bottom and on the edges of the ditch F
- cockpit and control 6 such as a cockpit and control 6.
- the propulsion unit 2 comprises an engine Ml mounted on a chassis la. supported by the track 3 towards the front thereof.
- This motor M1 drives the track 3 via a geared motor and a transmission known per se and not shown.
- the propulsion unit also includes a hydraulic pump P1 actuated by the motor M1 and whose role will be explained below.
- Other accessories such as the fluid reservoir necessary for the operation of the pump and the batteries have been intentionally omitted for the sake of clarification, as well as the connection circuits known per se.
- Two pads 7 are located on either side of the track 3 and towards the front of the latter.
- Each shoe 7 is articulated at the end of a link 7a, the other end of which is fixed to the frame 1a.
- Each pad 7 is controlled by means of a jack 8 mounted in an inclined position so that its piston rod can bring the pad 7 to bear on the edge BF adjacent to the ditch F.
- These retractable pads 7, controlled separately from the cockpit 6, each act to modify the direction of advance of the track 3.
- the jacks 6 are supplied from the pump P1.
- the spreading system 4 comprises a concrete storage hopper 10 which is placed above the track 3 at the rear of the propulsion unit 2.
- the hopper 10 ends at its rear end, beyond the rear end of the track 3, by a formwork 11, with a trapezoidal cross section, which extends, on the one hand, laterally on either side of the hopper 10 in the direction of the edges BF of the ditch F and, on the other hand, vertically towards the bottom FF of the pit F.
- the formwork 11 has a lower central opening 12 situated opposite the bottom FF of the ditch F.
- This opening 12 is delimited by the horizontal lower edges 13a, 14a, of two vertical front 13 and rear 14 walls, parallel, spaced and extending perpendicular to the longitudinal axis of the machine 1.
- These lower edges 13a, 14a are extend over a length substantially corresponding to the width of the bottom FF of the ditch F and are located at a height h thereof.
- the formwork 11 also has two lateral openings 15 which laterally extend the central opening 12. Each lateral opening 15 extends in width between the two front 13 and rear 14 walls, and in height over a length corresponding substantially to the height of the edge lateral adjacent BF of the concrete pit.
- Each lateral opening 15 is situated in a plane substantially parallel to the edge BF of the adjacent ditch and at a distance from it defined by the inclined edges 13b, 14b of the two front plates 13 and rear 14, which are separated by a distance d of the edge BF of the ditch F.
- Each lateral opening 15 is associated with a flap 15a mounted sliding in the plane of the opening 15 to modify its cross-section according to the concreting height of the edge BF adjacent to the ditch F, as shown diagrammatically in Figure 3.
- the concrete poured and stored in the hopper 10 is conveyed in the formwork 11 by means of an endless screw 20 situated in the bottom of the hopper 7 and extending along the axis of the machine 1.
- This endless screw 20 is rotatably supported at its two ends by two bearings 21a, 21b fixed to the two transverse end walls of the hopper 10.
- the worm 20 passes through the rear end wall 14 of the formwork 11 to be driven in rotation by an auxiliary hydraulic motor M2 supplied from the pump P1.
- the endless screw 20 rotatably supports two fins 22 which mix the concrete to project it laterally on the edges BF of the pit F through the lateral openings 15.
- the formwork 11 being open at its upper part corresponding to the rear part of the hopper 10, a deflector 24 is provided. to prevent the concrete stirred by the fins 22 from being ejected outside the formwork 11 ( Figure 1).
- the compression and smoothing system 5, FIGS. 1 and 5, is formed by a plate 25 of trapezoidal section slightly inclined from the front towards the rear.
- This plate 25 is fixed, by one end or front end, to the base of the rear wall 14 of the formwork 11.
- the distance separating the rear edge of this plate 25 from the ditch F fixes the thicknesses of the concrete layers on the bottom FF and on the lateral edges BF of the ditch F.
- the plate 25 comprises a central part 25a facing the bottom FF of the ditch and two inclined lateral parts 25b parallel to the edges BF of the ditch F.
- the inclined parts 25b. end with a 25s ledge. towards an edge of the adjacent BF ditch.
- This plate 25 is extended by a smoothing plate 26 for the layers of concrete and having the same trapezoidal section as the compression plate 25.
- the previously described spreading system 4 rests on a substantially horizontal chassis 1b supported by the track 3.
- This chassis 1b, FIG. 4 supports a stirrup 30 mounted to pivot about a horizontal axis 31 perpendicular to the longitudinal axis of the machine 1.
- This stirrup 30 is extended by a vertical rod 32 on which is fixed, by fasteners symbolized at 33, the front end surface of the hopper 10 to ensure the traction of the spreading system by the track 3.
- the structure of the machine 1 is completed by adjustment devices, on the one hand, for the thickness of the concrete layers and, on the other hand, for the stability of the spreading system.
- the device 40 for adjusting the thickness of the concrete layers is formed, in the example considered here. by two blades 41, 42 facing each other and respectively supported by the frame 1b and the base of the hopper 10. These blades extend perpendicular to the longitudinal axis of the machine 1 and are located towards the rear part of the track 3. Screws 43, situated towards the two ends of these blades 41, 42 pass through a blade to bear on the other blade in order to separate them from each other, causing a pivoting movement of the spreading system 4 forward around the axis of rotation 31 located at the front of the track 3.
- the height h defining the thickness of the layer deposited on the bottom FF of the ditch F and the distance d defining the thickness of the layers of concrete on the edges BF of ditch F are minimal. Any spacing between the blades 41, 42 therefore causes an increase in height h. and the distance d. Generally, this adjustment device only plays on a few centimeters.
- the device for adjusting the stability of the spreading system 4 comprises two retractable lateral pads 51 arranged on either side of the track 3, towards the rear of the latter.
- Each shoe 51 is articulated at the end of a link 51a. the other end of which is articulated to the chassis lfc., and is controlled to move by means of a jack 52 mounted in an inclined position so as to temporarily apply the pad 51 associated on the edge BF adjacent to the ditch F.
- the jacks 52 are ordered separately from cockpit 6 and supplied from pump P1.
- the entire spreading system 4 can pivot around the longitudinal axis of the machine 1, thanks to the clearance which is provided at its anchoring with the rod 32 secured to the chassis 1b carried by the track 3 (FIG. 4).
- the cockpit 6 comprises a set of levers 60 (FIG. 1), in particular those for controlling the motors Ml for driving the track 3 and M2 for rotation of the worm 20, the cylinders 8 for moving the steering pads 7, and the cylinders 52 for moving the stability pads 51.
- the person responsible for actuating these various controls mounts on a horizontal base 61 fixed on the top of the compression plate 25 for example ( figure 5).
- a horizontal auxiliary base 62, below the base 61, is fixed on the top of the smoothing plate 26 to allow a second person to monitor the operations and possibly perfect with a manual tool the imperfections of the smoothing of the layers of concrete.
- the operation of the machine 1 previously described easily follows from the structure of this machine.
- the machine 1 moves by its track 3 on the bottom FF of the ditch F.
- the concrete previously spilled and stored in the hopper 10 is driven by the worm 20 inside the formwork 11.
- the concrete falls directly by gravity by the central lower opening 12 on the bottom FF of the ditch F.
- the fins 22, driven in rotation by the worm 20, stir the concrete and eject it through the lateral openings 15 on the edges BF of the ditch F.
- the concrete thus deposited in a coarse thickness at the outlet of the formwork 11 is reduced to a thickness close to h in the bottom FF of the ditch F and to a thickness close to d on the edges BF, as the machine 1 advances, via the rear wall 14 of the formwork 11.
- this wall 14 forms a stop which limits the deposition of the concrete in the space between the ditch F and the compression plate 25.
- the thicknesses of the layers b1, b2 correspond to the values defined by h and d, these being generally substantially equal.
- the steering shoe 7, located outside the radius of curvature, is controlled in movement to come to bear on the adjacent edge BF to modify the direction of the track 3 accordingly.
- the pad 7 comes to bear on the edge BF of the pit depends on the radius of curvature of the ditch F and on the speed of advance of the machine 1.
- the stability pads 51 come or not bear on the adjacent edges BF of ditch F along the bottom profile FF of ditch F, in order to maintain the spreading system substantially in the axis of ditch F and to obtain substantially constant thicknesses of concrete layers.
- the machine as described can obviously be used for concreting irrigation canals, that is to say that its field of application is not limited only to ditches bordering roads or motorways.
- the components of the machine described by way of example can be replaced by means equivalent to the scope of the skilled person.
- the displacement system 3 can be constituted by two articulated and guiding tracks, mounted one behind the other, which makes it possible to remove the steering pads 7.
- the spreading system can be completed by two screws without additional end, housed inside the formwork 11, and which allow the concrete to be raised so that it is deposited in sufficient quantity on the edges BF of the ditch F, in particular when these edges must be concreted over a significant height.
- the screws 43 which are used to adjust the thickness of the concrete layers can be replaced by hydraulic cylinders.
- a wire mesh forming a reinforcement can be previously unwound on the bottom and on the edges of the ditch F, then embedded in the layers of concrete deposited by the machine to make reinforced concrete ditches. Finally, such a machine can also be remotely controlled or remotely controlled, according to known techniques already used for public works vehicles.
