Definitions

the present invention relates to a modular device for simultaneously spreading cut fibers and binders on a roadway and a spreading machine comprising such a device. It has applications in the field of civil engineering and in particular the construction or repair of pavements, especially for motor vehicles, but it can find applications for all types of flooring such as airstrips, port docks, sports surfaces, car parks, bike paths ...
a process for adding cut fibers to a binder which makes it possible to structure the binder layer in order to resist stripping due to traffic or transversal stresses or to limit the rise of cracks.
This method consists in spreading almost simultaneously, in the direction of progress of a spreading system, a binder layer followed by a layer of cut fibers itself covered by a second layer of binder. This operation is generally followed by the recovery of these layers by mineral aggregates or natural or synthetic to allow circulation.
the binder is generally an emulsion of bitumen.
These systems include continuous fiber cutter bars with number of cutters different from the number of bitumen emulsion spreaders that do not allow dosage variation or spread width without the risk of affecting process performance. .
the present invention proposes to solve in particular such problems with a device for simultaneous spreading of cut fibers and binders over a width of pavement, the device comprising longitudinally from front to back, a first set of spreading binders, a second set of spraying of cut fibers and a third spreading set of binders, the second set comprising tools for at least cutting continuous fibers, said tools being driven by a motor torque transmitting member.
binder means both binders in themselves as associations of binders with other elements such as powders, sands, or even aggregates, either stored ready or mixed with use. It is understood that in this case, the spraying means and in particular the nozzles and / or the pump and / or the storage means of the binders and any other elements and mixers, will be adapted accordingly.
the invention also relates to a machine for simultaneously spreading cut fibers and binders over a width of roadway, said machine being a self-propelled road vehicle with driving and control station, which comprises a device according to one or more of the characteristics previously listed as well as at least: a binder reservoir, a fluidification means for said binders, a means for pressurizing said binders for sending to the nozzles of the device, a reserve of continuous fibers, an air compressor and a reserve compressed air for at least the overpressure of the modules, said vehicle providing energy for actuating the engine torque transmission member of the device.
the system and the machine of the invention therefore comprise a number of cutters (continuous fiber cutting tools) identical to the number of lines of emulsion jets (there are two jets per line and per cutting tool) making it possible to reach amounts of 200 grams / m 2 of fiber or more. It allows a more homogeneous cross-section of fibers whose accuracy is at any point within 10% of the width of the pavement treated by spreading.
the modular structure allows variations in treatment width while respecting the dosage of fibers and binders over the treated width. This modularity also allows greater mechanical accessibility and ease of maintenance. The use of a maximum of easily removable and easy to handle equipment further improves the ease of maintenance.
each tool is removable individually and accessible in a few seconds for cleaning, adjustment, replacement of cutting blades or replacement by standard exchange. Because of its structure, the risk of accident during maintenance is reduced since the tools are no longer functional when they are accessible.
the system and the machine allow significant variations in flow rate for both the cut fibers and the binder, this independently for the selection of the fiber / binder ratio and in a dependent manner for a constant spread of material despite possible variations in spraying speed and change of working width.
the invention makes it possible to achieve increased reliability and repeatability, consistency in terms of respect for objectives, quantities applied, while offering the possibility of adapting large volume variations.
the reduced pressure value of the binder for ejection by the nozzles compared to known systems allows a considerable reduction of parasitic emissions and splash estimated up to about 50%.
an exemplary embodiment of the invention is presented in the form of a machine comprising a road vehicle 2 self-propelled four-wheel drive with, at the front, a driving and control cab 5 for an operator.
a reserve 9 of continuous fiber reels in a box 9 hooded which is up to access for an operator having opened the hood, can install and replace once these These are reels.
the trunk 9 is mounted at the front with a suspension for attenuating the effects of irregularities of the pavements at the trunk 9.
a set of pipes 10 makes it possible to route the continuous fibers towards the rear of the trunk. vehicle, in the spraying device 3, passing on the upper part of said vehicle.
the continuous fibers can pass backwards in a different manner and, for example, by lateral or even lower ducts.
the machine has an air compressor with a compressed air tank.
a new continuous fiber of a new reel after the previous reel has been exhausted and replaced by an operator, this
the latter manually engages the end of the continuous wire of the new coil in the front orifice of the pipe and then with a compressed-air gun sends compressed air through the same front orifice, which creates a front draft. back in the pipe that drives the fiber continues to the modules.
the vehicle 2 is a liquid fuel engine type fuel oil.
the tank comprises an access hatch at its upper part for filling.
a heating means is used for fluidizing the binders in the form of a burner 8, preferably automatic, light fuel which is taken from the fuel tank of the vehicle. Note that in variants not shown, the heating may be gas, heavy fuel oil or any other combustible substance, or even electricity.
the spraying device 3 is mounted on the rear of the vehicle chassis via a mobile hitch 4 ordered.
the movable linkage controlled is, in Figure 1, raised in the transport position, the device then being removed from the road.
the hitch may also be placed in a spreading position, the device then being close to the road, as will be seen later in connection with FIG. 2.
the mobile hitch also allows a lateral displacement of the device 3.
Suitable coupling means are used between the spraying device and the vehicle in order to allow the passage of binders, compressed air, continuous fibers, energy and control and control circuits in order to be able to follow the vertical movements and lateral translation of the device 3 between its working and transport positions.
the device 3 receives binders pressurized by the pump 6 by at least one flexible pipe not shown here.
the compressed air of the tank 7 is sent into the device 3 via flexible pipes.
the continuous fibers coming out of the pipes 10 to reach the device 3 are intrinsically flexible and can be pulled from the coils.
the spraying device 3 which is seen transversely in FIG. 1, comprises a set of modules each comprising two nozzles for projecting binders on the pavement and arranged at the front and at the back of a tool making it possible to pull the fibers. continue cutting and spreading them on the roadway.
the machine with the vehicle having the device at the rear and the continuous fiber reserve at the front has the following approximate dimensions: total length 4750mm, total width 1300mm, total height 2300mm, spreading width 1200mm.
the operational weight of the machine is about 4750kg and it can move between sites at a maximum speed of about 40km / h.
An automated microcomputer control system with display screen allows an operator in the cab of the vehicle to select operating modes (stopping certain modules, respective speeds of binders and / or cut fibers, speed of advance ...), to control and regulate the operation of the machine (flow rates in particular as a function of the speed of advance, regulation of the heating of binders ...), report anomalies and provide reports of the operational activity of the machine.
the device has 12 tools with cutters and 12 lines of binder jets (2 nozzles and therefore 2 jets per line).
the flow rate of cut fibers under control and according to demand between 0 and up to about 200 grams / m 2 while respecting a homogeneous transverse distribution producing no difference greater than 10%.
the rate indications given in the present application are indicative since they depend in particular on the speed of advancement of the device.
the capacity of the machine in storage, flow, speed, autonomy or other may vary depending on the achievements of all levels between machines for large jobs with large working width with a large number of modules and therefore also large storage volumes for sufficient autonomy and machines with smaller capacities.
Controlled valves are implemented in the fluid circuit of the binders in order to be able to cut the binder supply of each module (2 nozzles) individually, on demand.
all the modules are kept under pressure by compressed air, even those that are not functional, in order to avoid emulsion vapor rising towards the tools.
the overpressure of the modules can also have a favorable effect on the downward ejection of the cut fibers, the modules being open only downwards in the working position (and, preferably, also in the rest position thanks to a double articulation of the tools) and the flow of air can escape only from below.
Means for regulating the pressure in the fluid circuit of the binders acting on the pump 6 and / or for the compressed air can be implemented in order to keep the pressure at the level of the binder sprinkler nozzles or the pressure constant substantially constant. overpressure of the modules.
the tool engaging actuator and the binder supply valve of the two nozzles of a given module are controlled in parallel so that when the tool is stopped (or in the disengaged position ), the supply of binders to the nozzles is also.
Figure 2 shows the spreading device 3 in its spreading position, the control of the hitch 4 having lowered.
the tools 13 are actuated by functional engagement on a shaft the drive shaft 12 common to the various modules and itself actuated by a motor 11 disposed in the device and which receives energy from the vehicle.
the motor 11 is preferably hydraulic but in some variants can be mechanical, pneumatic or electrical, or other.
Each of the tools is removably mounted in its module between a release position where it is accessible to an operator outside the module and stopped and two positions where it is in the module: a working position where it is engaged and driven by the drive shaft and a rest position where it is stopped, then no longer in engagement.
the removable assembly of the tool 13 is pivoted on a hinge 17, the tool disengaging from the module upwards by tilting to give free access to the operator, backwards, to the rollers, cutting means, d drive and others, the latter being on a tilting tool frame, as will be seen later more precisely in Figure 6.
a second articulation within the tool it is possible to have a working position (in functional engagement on the drive shaft) and a rest position (non-engagement) while the tool is in the module and the closed module.
the transition from the working position to the rest position, and vice versa, is obtained by implementing a pneumatic actuator 16 which acts on the tool to put it into functional engagement or not on the drive shaft 12
a single articulation, of the type of that referenced 17 can achieve the three positions indicated above, clearance, work and rest.
Figure 3 schematic top view of the machine, allows to find some of the previously described elements.
FIG 4 allows to see more precisely the spreading device 3 in top view while the tools 13 are in place in their modules.
the transmission between the motor 11 and the drive shaft 12 is preferably belt-driven, although other means can be used (chain or gears) or even the drive is direct.
the engine is preferably hydraulic as previously indicated.
Figure 5 allows to see more precisely the spraying device 3 in top view while the tools 13 have been removed from the device 3. It can be seen in particular the actuators 16 allowing or not the functional engagement of the tool with the drive shaft 12. It can also be seen on the drive shaft 12, in each module, an element (rubber wheel type) for this functional tool outlet. Furthermore, bearings (preferably ball or roller bearings) are implemented at some of the separations between modules and at both ends of the device 3 to maintain the drive shaft.
the drive shaft 12 may be continuous across the device or not.
the tools being accessible by tilting, it is not necessary to disassemble the entire module to perform repairs on the tools and can therefore implement a continuous drive shaft.
modules which each comprise a driving shaft section with complementary engagement means at both ends of the section so that when two modules are joined together , the two sections are in drive rotation between them.
Figure 6 shows how the tool 13 of a module is pivotally mounted because it is shown in its disengaged position, tilted upwards and accessible to an operator and in its position inside the module. working position.
Each of the tools of the modules comprises a first axis 19 on which is the portion engaging on the transmission member 12 by friction to transmit the torque / rotational movement to a cutter wheel.
a rubber wheel (or other material) is mounted integral with the body of transmission 12 and it is through this wheel that can be engaged the cutter wheel.
the tool further comprises on a second axis a pressure roller 21 rotatably mounted which keeps the continuous fiber in contact with the cutter roller to allow cutting.
the pressure of the pressure roller is provided by an adjustable spring system 23 for compensation of wear and pressure adjustment.
a holding roller 22 also mounted free to rotate on a third axis, allows the maintenance of the continuous fiber on the pressure roller 21 upstream of the cutting roller 20 while avoiding the rearward disengagement of the continuous fiber when the tool is at rest.
the position of the retaining roller 22 is adjustable and is spring loaded for wear compensation.
These elements, axes and rollers, are mounted on a hinged support 24 which allows, according to its position, the setting work position or in the rest position of the tool. This support is itself mounted hinged at 17 relative to the frame of the module to allow the complete tilting of the tool out of the module in a position of release of the tool for cleaning operations, maintenance or replacement of the elements.
compressed air can be sent to a part of the binder circuit so that it can be emptied and cleaned at the end of a construction site, in particular to prevent the nozzles from becoming clogged.
the device may be associated with a specific trailer independent of the vehicle for its movement.
the distribution of the associated elements is carried out as required, from the trailer. having only the spreading device with possibly the reserve of fibers, the other elements being with the vehicle, to the trailer with all these elements.
the device that is similar to a spreading boom can be of fixed or variable width (telescopic or tilting ramp type) possibly allowing different spreading widths and a small footprint when transporting a site to the site. other.
the capacity of binder tanks, air or other can be adapted depending on the machine, especially to larger volumes.
the spreading device can be used for the realization or the repair of traffic pavements (or others) and in which, in general, it is carried out a subsequent recovery by aggregates, it can also be implemented to achieve a fastening layer which may optionally be structuring or still used for finishing.
