Definitions
- the subject of the invention is a device mounted on a vehicle for transporting materials such as waste with a view to their compression and ejection. It relates more specifically to any type of carrier vehicle such as a semi-trailer (with two or three axles) trailers, trucks, fixed or mobile container of the simple or multi-bucket type with hooks, chain or cable.
- the invention aims to provide an original solution to the problem of transport and especially the horizontal ejection of waste when one aims to achieve an optimum number of transport.
- it is possible to operate safely and on any type of terrain with the help of qualified personnel adapted to the operation of the various devices necessary for the various tasks. These tasks are essentially: the collection of different products (waste), their compression, and finally their ejection.
- US-A-4,013,181 (R.N. Johnson) describes a vehicle in which a compression and material unloading system is on board.
- the system essentially comprises a shield movable in longitudinal translation along a pair of rails. Maximum elongation of the system in translation is only possible on condition that the material ejection door is open.
- Figure 1 and especially Figure 4 show that the working section of the system is circular.
- the shield is reinforced (figure 4) using a rear structure in the shape of a hexagon.
- the system is actually a type of ram that can be mounted and dismounted on specially adapted service vehicles.
- Document FR-A-2 747 350 (J P Sauvion) describes a technical solution studied to improve the evacuation and horizontal ejection of waste.
- the assembly is designed to implement an ejection shield whose center of gravity is low, the whole being part of a reinforced body structure with a curved cross section in the shape of an arc of a circle.
- the bucket is provided with an expulsion shield (16) ( Figure 2 of the document) mounted at the end of a thrust cylinder and completely sweeping the walls of the bucket between two rest and discharge positions. The latter is done by a flat flap perpendicular to the horizontal axis of the vehicle.
- a symmetrical pair of longitudinal members provides rigidity and has a hollowed out shape which accommodates in its central part conduits for actuating fluids and / or electrically conductive cables.
- FR-A-2 759 335 (GIRARD CR) relates to a device for a semi-trailer with two or three axles; .the device implements a shield, a double-acting cylinder provided with a anti-buckling device with guidance on two rails and armature collar for the cylinder.
- FR-2 766 801 (J-R LEGRAS) relates to a transporter which has the function of loading, compressing and unloading containers filled with compressible material.
- the container has a circular section and it is coupled to the compression system which constitutes a separate entity.
- the present invention aims to reduce such high investment and operating costs. While betting to implement a circular shield structure in which the overall mechanical strength is ensured, the invention provided an original solution without exaggerated repercussions on the total cost.
- the solutions provided to the problems of the tank with a piston / shield type structure mainly relates to geometry. It has in fact been ensured that the axial symmetry with respect to a cylinder (the axis of which would be the jack) is kept in an optimal manner, however severe the conditions of use of the equipment are.
- a tank wall thickness of 4 mm is, according to the invention, implemented and an optimal number of reinforcing elements is used; these results are possible and are achieved due to the design of the compression ram.
- This ram has a circular percussion shape and is reinforced by a rear shield structure.
- This rear ram structure is such that the whole looks like a diabolo. The front and the back of this diabolo are crossed by the jack.
- the impact impact forces (especially if the waste is rectilinear elements like piles or beams) have for resulting a force whose direction is certainly not axial. This force is a stress of major importance for the stability of the operation and against the deformation of the ram.
- shield / diabolo The geometrical form of the shield is the form which one will agree to call hereinafter, "shield / diabolo". It minimizes the potential energy of the structure for a given situation of forces (moments and forces) and displacements (angular and radial).
- the assembly (through cylinder, shield) in translation is, according to the invention, guided using an angle welded to the inside of the tank over the entire length thereof so as to prevent the rotation of the circular shield.
- Any couple of conjugate forms is obviously possible according to the invention.
- the telescopic guide allowing the rectilinear sliding of the cylinder secured to the shield is greatly facilitated by the form of "ram / diabolo" mentioned above, because the ram / diabolo "has a lateral surface which is tangent to the tank cylinder over the entire tank length
- the invention in its essential lines therefore relates to a device mounted on a vehicle of the type of a waste transport bucket provided with waste inlet hatches for compression and ejection, comprising a reinforced cylindrical circular structure , a circular compression and ejection shield movable in translation along the axis of the structure, said translation being provided by a telescopic jack.
- the assembly is such that the cylindrical structure, the telescopic jack, coaxial with the tank, the circular compression / ejection shield are slidably mounted in the manner of a piston in a cylinder, in an overall configuration such that the thrust of the jack, on the shield, the reaction to this thrust, the result of the compression forces, the overall reaction on the ends of the bucket, have a value substantially zero and of axial direction, the moment resulting from these forces being negligible.
- said overall configuration is produced by a cylindrical and circular structure, the two ends of which are respectively, at the front, a conical or convex bottom, housing the telescopic assembly and the anchor parts of the thrust shield and, at the rear, a door which has the shape of a pair of cylinders, one coaxial with the tank, the other with an axis perpendicular to the axis of the first, this rear part serving as a door for closing the tank or bucket with a horizontal pivot axis.
- the invention relates to a device mounted on a vehicle of the type of a waste transport bucket provided with waste inlet hatches for compression and ejection, comprising a structure reinforced cylindrical circular, a circular compression and ejection shield movable in translation along the axis of the structure, said translation being ensured by a telescopic jack coaxial with the tank, the device implementing an anti-rotation guide which is produced for allow rectilinear sliding of the shield in the tank using a conjugate device welded according to a generator over the entire length of tank and located in the upper part thereof.
- Another way of presenting the invention consists in considering it as a device mounted on a vehicle of the type of a waste transport bucket provided with waste inlet hatches for compression and ejection, comprising a structure reinforced cylindrical circular, a circular expulsion shield movable in translation along the axis of the structure, said translation being provided by a telescopic jack coaxial with the tank.
- the peculiarity resides in that the shield is crossed by said jack to constitute, in the rest position of the jack, an assembly of minimum volume, said jack being protected by a coaxial saber which receives the waste during their entry by the hatches.
- the device of the invention is mounted on a vehicle of the type of a waste transport bucket provided with waste inlet hatches for their compression and ejection, comprising a reinforced cylindrical circular structure.
- the device has a circular expulsion shield movable in translation along the axis of the structure, said translation being provided by a telescopic jack coaxial with the tank.
- the shield stands out because it is crossed by a jack to constitute in the rest position of the jack a set of minimum volume, said jack being protected by a coaxial saber which receives the waste when it enters through the doors.
- the telescopic cylinder is a four-element cylinder and there is associated with it an anti-buckling equipment.
- This anti-buckling equipment is a metal structure in the form of a compass, the central part of which is fixed to the periphery of the jack and the branches of which are a pair of metal tubes of equal length making between them an angle of substantially 60 ° and each mounted on a wheel rolling along the generatrix of the cylindrical tank during the translation of the jack, to ensure the adhesion of the wheel to the tank surface and the balancing of the telescopic jack.
- These two properties, at maximum elongation, are achieved by adjusting a calibrated spring housed in an inner leg to the metal tubes.
- the invention finally relates to a device as mentioned above in which the telescopic compression and ejection cylinder the actuating and locking cylinders of the waste inlet doors and the closing door are controlled by departure of an independent hydraulic power generator group on board the vehicle.
- a special feature of the invention is that the control of the telescopic compression and ejection cylinder is conditioned by the hydraulic pressure signal delivered by a limit switch of the telescopic compression and ejection piston so as to guarantee operational safety: stopping / blocking the telescopic compression and ejection cylinder at a distance greater than the length of the saber if the door is closed and authorization to deploy said cylinder at maximum elongation if the door is opened.
- the invention should be considered as a device mounted on a vehicle of the type of a waste transport bucket provided with waste inlet hatches for their compression and ejection, comprising a reinforced cylindrical circular structure, a circular compression and ejection shield movable in translation along the axis of the structure, said translation being ensured by a telescopic jack (1) coaxial with the tank, the originality of the device being that said circular shield is a ram which has a circular percussion shape and which is reinforced by a rear shield structure, which is such that the assembly has the appearance of a diabolo, totally crossed by the jack so that the translation of the ram in the tank or bucket takes place as the displacement of a sliding piston in the cylinder of an internal combustion engine.
- Figure 1 is a pair of lateral (la) and horizontal (lb) views of the vehicle equipped with the device according to the invention.
- Figure 2 is the illustration of the rear part of the vehicle which has the shape of a tilting door
- Figure 3 is an illustration of the telescopic cylinder used according to the invention .
- Figure 4 is an overall representation, using two projections, of the relative arrangement of the hatches, the jack, the shield and the conical or convex bottom of the vehicle according to the invention. It illustrates in particular very clearly the eight reinforcements.
- Figure 5 is an overall representation using two projections of the relative arrangement of the protective saber, the ram / diabolo, the cylinder used according to the invention. It illustrates the form of diabolo with its eight fin ..
- Figure 6 schematically illustrates the model adopted for locking the doors.
- U Figure 7 illustrates the mechanism for opening the two doors.
- Figure 8 shows the cylinder buckling prevention crew .11 is in a way a carrying carriage.
- Figure 9 shows the function of the anti-buckling system when the actuator has been deployed on large diameters (diameters I, II) and when the rear door is open, the smallest diameter (diameter IV, see Figure 9) is deployed and actuated so as to exert the expulsion force on the compacted waste to the maximum.
- Figure 1 shows that the tank (4) has a cylindrical shape; a pivoting door (11) actuated hydraulically around a horizontal axis closes the compression / transport enclosure.
- a vertical shield (2) of compression and ejection is displaced by the action of a horizontal telescopic double-acting cylinder.
- the thrust that said cylinder can exert is between 500 and 1500 kN.
- a double loading hatch (7,8) with two hatch leaves is arranged horizontally in the upper part of the cylindrical tank (4), in the immediate rear rear of the shield ( 2) when the latter is in its initial position, at the start.
- the loading hatch (7,8) (figure 7) is locked: the twin jacks which actuate it can be put into operation even if the stop command for operation of the compression jack is engaged.
- Hydraulic controls are in fact annexed in connection with an on-board central unit which supplies, thanks to the Diesel group (10, FIG. 1), the hydraulic energy essential for the operation of the various jacks, for compression / ejection and for closing / locking of the enclosure cylindrical (4).
- FIG. 2 is the illustration of the rear part of the vehicle which has the shape of a tilting door (11).
- This tilting door (11) is therefore the termination of the tank or bucket (4). Its shape is specific since it is that of a pair of cylinders, one coaxial with the tank: a first cylinder has an axis perpendicular to the axis of the second cylinder, this rear part serving as a door for closing the tank or bucket is mounted for rotation, about a horizontal axis of rotation and strictly perpendicular to the axis of the telescopic translation cylinder (1).
- the door (11) is illustrated in the gaping position (upper left part of the drawing), and in the closed position (right part). Finally a rear view of the door is given at the bottom of the drawing.
- the cylinders (21) are as illustrated in Figure 2 (bottom part) .
- the weight of the rear door (11) associated with the geometric shape of the stopper (22) prevents the door from opening, regardless of the thrust and / or pressure exerted by the telescopic compression / ejection cylinder (1).
- the open position of the door (11) which is visible in Figure 2 (left part) is reached when the cylinders (21) are actuated.
- the action of the jacks (21) has the primary effect of lifting the door (11) and releasing it from the stop cleats (22).
- the cylinders (21) are double-acting cylinders whose stroke is adjustable by the operator and it is therefore understood that the opening amplitude of the door (11) is completely controlled.
- the actuators (21) are started up by a separate control.
- the opening of the enclosure (4) is accessible to the operator who controls the speed of deployment of the jack. He can therefore separate, according to his judgment, the phases of deployment of the jack (21) which lifts the door (11) and marks a downtime before restarting so that the jack performs the rotational movement.
- Total safety during unloading is guaranteed by the following technical provisions and operations: stopping / blocking the telescopic cylinder (1) for compression and ejection at a distance greater than the length of the saber if the door (11) is closed and authorization to deploy said cylinder at maximum elongation if the door (11) is open. At this time, the appearance of the deployed cylinder is that visible in FIG. 9.
- FIG. 3 illustrates an essential part of the on-board waste compression / ejection device according to the invention.
- the telescopic cylinder (1) used is of the telescopic type with double effect .double wall for the hydraulic return, and with four elements.
- the cylinder can stop at any point of the stroke.
- the bottom of figure 3 shows the four elements in section perpendicular to the axis of the cylinder (1).
- the total length of the cylinder, not deployed is 3.4 meters. At maximum elongation, its length is 10.85 meters. For this maximum elongation, the phenomenon of buckling of the four deployed and nested telescopic beams can take place. For this reason, the crew shown in Figure 8 has been planned.
- the jack is, on the one hand fixed by its anchored end (18) to the conical or domed front of the tank (4) and on the other hand, by the bearing / journal (19) to the shield.
- the cylinder is controlled to extend into four double-effect expansions thanks to gradually decreasing diameters.
- the dimensioning of this equipment is the responsibility of those skilled in the art and will not be discussed in this presentation.
- the pressures / flows, upstream / downstream of the hydraulic regime adopted are omitted and do not form part of the innovative field of the present invention.
- the compression phase carried out by the cylinder is carried out by putting into service the two largest diameters of the double-acting cylinder. It involves a total length of 5.54 meters. Without counting the time for handling the controls, the round trip of the two large diameter elements takes only two minutes forty five. Similarly, without counting the time for handling the controls, the round trip of all the elements takes only three minutes forty two.
- FIG. 3 is therefore that of a hydraulic jack with a double-acting jacking cap (18) used in the context of the invention. It is a double-walled cylinder, four telescopic elements (1,11, III IV) visible in section at the bottom of FIG. 3.
- the cylinder according to the invention has a distribution of cylinder diameters, which is asymmetrical. Large diameters (IV; III) - Small diameters (I, II). (see figure 3) this distribution is necessary to carry out the two fundamental works in a sequential way: the work where the compression is carried out; that where the waste is ejected (forces put less stake).
- the maximum thrust provided by the large diameter (diam 280 mm) is 135 kN.
- the smallest diameter (125 mm) gives 27 kN.
- the 240 mm diameter cylinder has a flat (26) which accepts a fixing flange (26bis) of a cylinder carrying carriage; this carriage is in fact an anti-buckling equipment as shown in Figure 8.
- the compression amplitude is 5.54 m.
- a cylinder return trip lasts 2 '45 "in compression work.
- the pushing force is, as already specified, less; it is exerted, for safety, provided that the door (11) is gaping. This question has already been explained in the presentation.
- cylinder, that which is carried out at the ejection is 10.85 m.
- the operating time there and back is 3 '42 ".
- Figure 4 is a representation of the relative arrangement of the various pieces of equipment: hatches, cylinder, and the conical or domed bottom of the vehicle according to the invention.
- the shield is therefore located in a certain location, between the last two stiffeners, on the left, in the figure.
- the expression 'shield' is used here because of the choice of the geometric shape of the shield, as it is desired according to the invention, namely the diabolo shape, the shield reinforced in this way will effectively act as ram.
- the purpose of Figure 4 is also to illustrate the proportions of length adopted for the location of the jack, at rest under the double hatch (7,8).
- the bottom of the figure also illustrates the conical bottom located at the front of the trailer.
- Eight reinforcements (24) can be seen there, the function of which is to guarantee the mechanical rigidity of the bottom by ensuring a reaction to the thrust (directed towards the front of the trailer) of the jack during its compression path.
- Two trapezoidal lights (30) allow access for inspection of the telescopic cylinder.
- FIG 5 wanted to illustrate the diabolo shape of the shield.
- the relative angular locations of the fins (29) are those shown (A1, ..., A8), in Figure 8. They are eight in number.
- the fins ensure the mechanical rigidity of the face in contact with the waste and the guide cylinder.
- the rigorous cylindrical symmetry is obviously guaranteed by the angular distribution Al, A2, ... A8.
- Figure 6 schematically illustrates the model adopted for locking the doors. This is a common mechanism that has been adopted because of its simplicity. It is operated by staying at the bottom of the tank from commands on a portable keyboard. The controls are connected to the hydraulic unit by flexible cables. All these aspects of practical implementation details are neither taken up nor specified in more detail since their implementation has no impact on the essential innovative aspect of the invention.
- Figure 7 illustrates the mechanism for opening the two doors. This opening is also controlled by staying at the bottom of the vehicle. The order carried out is that of the opening cylinders which are anchored to the left and right fixing points (26)
- the two figures 4 and 5 respectively show the circular arrangement of the domed bottom for fixing the jack (fig. 4) and the circular arrangement of the ram / dolly according to the invention (fig. 5).
- the upper part of Figure 5 shows the configuration and the shape which guarantees the reinforcement of the mechanical resistance of the ram / diabolo. Elements possibly located in parallel planes have been folded down in the plane of the drawing.
- the anti-rotation geometrical arrangements which are profiles of conjugate shape (5) are visible in the fourth part of the circumference.
- the shape shown here is a triangle. Other forms (single or multiple) can be adopted. It is imperative that they are located in the first or fourth quadrant.
- the traces of the fins (29), joining the front part of the ram / diabolo (2) and its rear face are visible.
- the reinforcing fins (29), A1, ..., A8 are eight in number (see references A1 .... A8.
- the circular edge of the front face of the ram / diabolo is machined with an abrasive fillet which presence is important when the telescopic cylinder (1) is in maximum elongation as visible in FIG. 10. The purpose of this leave is to rid the waste expulsion zone of residual traces which would clump together during use despite the cleaning efforts
- the upper part of Figure 4 shows the location of the characteristic elements of the curved bottom: reinforcements (24), lights (30) The rigorous cylindrical symmetry is obviously guaranteed by the angular distribution adopted.
- Figure 8 shows the cylinder buckling prevention crew. It is held by a flange (26) and comprises two legs (14) which are movable in translation and roll along the tank thanks to the rollers (15). At the start of an operational campaign and periodically, the equilateral triangle formed by the legs and the lower rod / reinforcement are balanced using the spring (16) adjustable by the setting hole (13) of the ' spring. This type of mechanical arrangement is usual in the translation mode of a cylinder of great length. Other types of anti-buckling equipment can be applied in conjunction with the concepts of the invention, without going beyond the scope of the latter.
- the volume under the double hatch (7.8) is filled with waste material during the first loading.
- the material is pushed towards the rear of the vehicle by moving the shield back and forth (2) along the entire extension of the hatch (7,8).
- the tank area (4) which is inside and under the hatch is thus cleared. This operation is carried out repeatedly. After a few operating cycles, the waste, constantly urged to push, undergoes compression and, at this time, the shield (2) makes a large translation backwards with a greater elongation. , close to the maximum value so that the materials are compressed as much as possible.
- the shield is then returned to its starting position.
- the shield is returned to its maximum stroke, but in this case, its elongation is less than during the previous stroke. This is continued until the time when additional waste is no longer possible.
- the authorized payload is then reached. Its value is 44 Tons in Belgium (complete coupling: tractor + trailer + load).
- Figure 9 will further understand the deployment mode of the telescopic cylinder (1).
- the translation of the shield / diabolo (2) according to the invention takes place gradually.
- the various cylinders visible in section in Figure 3 are deployed.
- the first two diameters 280 and 240 mm respectively, arrive at the end of the race at a certain time; at this time the anti-buckling equipment which is visible in FIG. 8, and which is fixed by the system described is still in its initial position but begins to move towards the middle of the tank during the deployment of the two more elements small diameter.
- the anti-buckling system is in the optimal location to ensure an anti-buckling reaction against the self-weight of the deployed cylinder and against any vertical component of the forces exerted on the cylinder during its operation.
- Figure 9 also shows the function of the anti-buckling system when the cylinder has been deployed on large diameters (diameters I, II) and when the rear door is open, the smallest diameter (diameter IV, see Figure 9) is deployed and actuated so as to exert the expulsion force on the compacted waste to the maximum.
- the diabolo type shield In the fully deployed state, the diabolo type shield is in an extreme position: the edge of the peripheral circumference of the front part of the shield is tangent, at the rim of the tank over the entire inner circumference of the cylinder delimiting the tank or bucket (4). Adequately, the rim is machined worked to present along its length, a cavet, or leave whose function is to ensure a scraping effect.
- a hydraulic group (10) visible in FIG. 1 and placed, as can be seen, under the tank. (4).
- this hydraulic group (10) is a diesel engine not shown.
- This diesel engine is autonomous with a fuel oil tank (9), ( Figure 1); it drives a hydraulic pump, not shown which allows the hydraulic oil to be pressurized from the supply network of the compression / ejection cylinders and the closing / opening of the cylindrical enclosure (4).
- the hydraulic oil is contained in the tank (12).
- the various tanks are also attached to the semi-trailer.
- the device according to the invention is intended first of all to equip road semi-trailers for the transport of materials to the sites of landfill / treatment of urban waste. None is opposed to the equipment and the device according to the invention being used for the transport of compressible materials, certain minimal adaptations being made which do not go beyond the scope or the extension of ideas and concepts founding the invention.
