Description

Système de fixation de la mâchoire mobile d'un broyeur à cône ou giratoire System for fixing the movable jaw of a cone or gyratory crusher
La présente invention concerne un système de fixation de la mâchoire mobile d'un broyeur, à cône ou giratoire. Les broyeurs à cône et les broyeurs giratoires sont destinés aux installations de mines ou de carrières et servent à la réduction de la taille des granulats et des minerais à des dimensions requises par leur utilisation ultérieure.The present invention relates to a system for fixing the movable jaw of a grinder, cone or gyratory. Cone crushers and gyratory crushers are intended for mining or quarrying installations and are used to reduce the size of aggregates and ores to dimensions required for their subsequent use.
Ils comportent une cuve de broyage tronconique, dont la paroi supporte une mâchoire fixe, et une tête conique portant la mâchoire mobile montée sur un arbre coaxial à la cuve. L'axe géométrique de la tête conique fait au sommet de celle-ci, un certain angle avec l'axe de l'arbre principal, ce qui donne à la tête, lorsque l'excentrique tourne, un mouvement de nutation. Lors de leur descente dans la cuve, les matériaux sont progressivement broyés jusqu'à atteindre la dimension du plus petit espace r entre la mâchoire fixe et la mâchoire mobile, au niveau de la base de la tête en nutation et situé en 2 sur la figure 1 montrant un broyeur à cône.They include a frustoconical grinding tank, the wall of which supports a fixed jaw, and a conical head carrying the movable jaw mounted on a shaft coaxial with the tank. The geometrical axis of the conical head makes at the top of this, a certain angle with the axis of the main shaft, which gives the head, when the eccentric turns, a nutation movement. During their descent into the tank, the materials are gradually crushed until reaching the dimension of the smallest space r between the fixed jaw and the movable jaw, at the base of the nutation head and located in 2 in the figure 1 showing a cone crusher.
Le broyeur à cône selon la figure 1, comporte une trémie d'alimentation 8 située au-dessus de l'ouverture 1 d'une chambre de broyage ou cuve 3. La tête de broyage 5 est supportée par un arbre 10 au-dessus d'un palier de celui-ci, avec son axe géométrique faisant, grâce à un excentrique 12, un angle α avec l'axe de l'arbre de façon à avoir un mouvement de nutation lorsque l'excentrique 12 tourne. La mâchoire fixe 11 est fixée sous l'ouverture 1, à la partie supérieure de la cuve 3.The cone crusher according to Figure 1, includes a feed hopper 8 located above the opening 1 of a grinding chamber or tank 3. The grinding head 5 is supported by a shaft 10 above d 'a bearing thereof, with its geometric axis making, thanks to an eccentric 12, an angle α with the axis of the shaft so as to have a nutation movement when the eccentric 12 rotates. The fixed jaw 11 is fixed under the opening 1, to the upper part of the tank 3.
La mâchoire mobile 4 est montée sur la tête 5 et repose en partie basse sur la tête 5, tandis qu'elle est serrée en partie haute sur la tête par une vis 6, par l'intermédiaire d'un anneau 7. Ce serrage est réalisé par une composante de la force de serrage de la vis 6 dirigée selon la génératrice du cône de la mâchoire mobile 4.The movable jaw 4 is mounted on the head 5 and rests in the lower part on the head 5, while it is tightened in the upper part on the head by a screw 6, by means of a ring 7. This tightening is produced by a component of the tightening force of the screw 6 directed along the generatrix of the cone of the movable jaw 4.
Au cours du travail de broyage, les pièces qui s'usent le plus vite sont les mâchoires et notamment cette mâchoire mobile 4. De ce fait, celle-ci doit être changée périodiquement après usure. En effet, lorsque le matériau à broyer est constitué de silice pure, la durée de vie de la mâchoire 4 peut ne pas dépasser quelques dizaines d'heures. Par contre, lorsqu'il s'agit de calcaire, cette durée de vie peut aller jusqu'à plusieurs années.During the grinding work, the parts which wear out the fastest are the jaws and in particular this movable jaw 4. Therefore, it must be changed periodically after wear. In fact, when the material to be ground consists of pure silica, the life of the jaw 4 may not exceed a few tens of hours. On the other hand, when it comes to limestone, this lifespan can go up to several years.
A cette fin, elle est fixée de façon amovible sur la tête au moyen de la vis 6. Le serrage de cette vis 6 demande une force très élevée afin d'éviter à la mâchoire de battre sur la tête. Pour la serrer, on utilise en général une clé sur laquelle l'opérateur tape avec une masse. De plus, au cours du travail, la mâchoire mobile 4 a tendance à tourner sur la tête mais, par ce mouvement, elle entraîne la vis 6 qui s'auto serre en maintenant la mâchoire. L'auto serrage de la vis fait que le démontage exige aussi l'application d'une force très élevée. Afin de faciliter le démontage, un anneau 7 est intercalé entre la tête de vis et le bord supérieur de la mâchoire mobile. Pour le démontage, cet anneau est coupé au chalumeau et dégagé avec un outil approprié, ce qui libère la vis qui peut alors tourner librement.To this end, it is removably attached to the head by means of the screw 6. The tightening of this screw 6 requires a very high force in order to prevent the jaw from beating on the head. To tighten it, we generally use a key on which the operator taps with a sledgehammer. In addition, during work, the movable jaw 4 tends to turn on the head but, by this movement, it drives the screw 6 which self-tightens while holding the jaw. The self-tightening of the screw means that disassembly also requires the application of a very high force. To facilitate disassembly, a ring 7 is interposed between the screw head and the upper edge of the movable jaw. For disassembly, this ring is cut with a torch and released with an appropriate tool, which frees the screw which can then turn freely.
Afin de faciliter le montage et le démontage de la mâchoire, selon la demande de brevet français n° 02 09256, le système de fixation comporte un élément de blocage, dont le diamètre est au moins égal à celui du sommet du cône de la mâchoire mobile, qui est pourvu de trous répartis sur sa périphérie, dans lesquels sont enfilés des vis se vissant dans des taraudages situés dans la tête ou une pièce solidaire de celle-ci.In order to facilitate the assembly and disassembly of the jaw, according to French patent application n ° 02 09256, the fixing system comprises a locking element, the diameter of which is at least equal to that of the top of the cone of the movable jaw , which is provided with holes distributed over its periphery, into which are threaded screws which are screwed into threads located in the head or a part integral with the latter.
Selon une forme de réalisation du broyeur à cône présenté dans cette demande, l'élément de blocage est constitué en deux parties, par un plateau de blocage pourvu de trous répartis sur sa périphérie et un goujon de blocage situé au-dessous, vissé dans un taraudage axial de la tête et solidaire en rotation avec ledit plateau, le serrage s'effectuant au moyen de vis traversant les trous du plateau et se vissant dans les taraudages pratiqués dans le goujon de blocage. Selon cette demande toujours, dans le cas d'un broyeur giratoire, l'élément de blocage est constitué par une rondelle de blocage pourvue de trous répartis sur sa périphérie ; une écrou de serrage, vissé sur l'arbre au-dessus de la tête et solidaire en rotation de ladite rondelle de blocage, le serrage s'effectuant au moyen de vis traversant les trous de la rondelle de blocage et se vissant dans des taraudages pratiqués dans ledit écrou de serrage.According to one embodiment of the cone crusher presented in this application, the blocking element is constituted in two parts, by a blocking plate provided with holes distributed on its periphery and a blocking pin located below, screwed in a axial tapping of the head and integral in rotation with said plate, the tightening being effected by means of screws passing through the holes of the plate and being screwed into the threads formed in the locking stud. Still according to this request, in the case of a gyratory crusher, the blocking element is constituted by a blocking washer provided with holes distributed over its periphery; a clamping nut, screwed onto the shaft above the head and integral in rotation with said blocking washer, the clamping being effected by means of screws passing through the holes in the blocking washer and being screwed into tapped holes in said tightening nut.
La solution selon la demande précitée convient parfaitement pour faciliter le montage et le démontage de la tête mobile. Toutefois, un serrage fort est encore nécessaire pour empêcher la mâchoire de tourner par rapport au plateau de blocage ou à l'écrou de serrage (broyeur giratoire). Il convient donc de trouver une solution au problème de la solidarisation en rotation du plateau (ou de l'écrou) et de la mâchoire.The solution according to the aforementioned request is perfectly suited to facilitate the assembly and disassembly of the movable head. However, strong tightening is still necessary to prevent the jaw from rotating relative to the locking plate or the clamping nut (gyratory crusher). It is therefore advisable to find a solution to the problem of securing in rotation the plate (or the nut) and the jaw.
Pour résoudre ce problème, l'invention prévoit dans un système que ledit élément, présente sur sa périphérie extérieure des encoches dirigées radialement vers l'extérieur et régulièrement réparties sur ladite périphérie et que la mâchoire mobile présente, sur sa périphérie intérieure, au niveau de son ouverture des tenons dirigés radialement vers l'intérieur, régulièrement répartis sur ladite périphérie et en nombre égal auxdites encoches, les tenons pénétrant à l'état monté dans lesdites encoches afin de solidariser l'élément de blocage et la mâchoire mobile en rotation pendant le fonctionnement du broyeur.To solve this problem, the invention provides in a system that said element, has on its outer periphery notches directed radially outward and regularly distributed over said periphery and that the movable jaw has, on its inner periphery, at the level of its opening of the pins directed radially inwards, regularly distributed over said periphery and in number equal to said notches, the pins penetrating in the assembled state into said notches in order to secure the locking element and the movable jaw in rotation during the operation of the crusher.
Selon l'invention, le nombre de tenons et des encoches est de préférence égal à quatre. Il peut toutefois être inférieur ou supérieur, étant entendu que le nombre d'encoches est au moins égal au nombre de tenons.According to the invention, the number of studs and notches is preferably equal to four. It can however be lower or higher, it being understood that the number of notches is at least equal to the number of studs.
L'invention sera mieux comprise au moyen d'un exemple de réalisation non limitatif décrit ci-après et représenté sur le dessin annexé sur lequel sont représentées : Figure 1 : Une coupe schématique d'un broyeur à cône selon la technique antérieure ;The invention will be better understood by means of a nonlimiting exemplary embodiment described below and shown in the appended drawing in which are shown: Figure 1: A schematic section of a cone crusher according to the prior art;
Figure 2 : Une vue de dessus en perspective de la mâchoire mobile selon la présente invention ;Figure 2: A perspective view from above of the movable jaw according to the present invention;
Figure 3 : Une coupe schématique de la fixation de la mâchoire mobile d'un broyeur à cône selon l'invention ;Figure 3: A schematic section of the attachment of the movable jaw of a cone crusher according to the invention;
Figure 4 : Une vue en coupe selon la ligne V-V de la figure 3.Figure 4: A sectional view along line V-V in Figure 3.
Comme le montre la figure 3, la mâchoire mobile 4 est disposée sur la tête conique 5 et repose classiquement, comme le montre la figure 1, sur la partie inférieure large de la tête conique. Son serrage dans cette position s'effectue au moyen d'un élément de blocage constitué par une vis en deux parties, un plateau de blocage 16 dont le diamètre est au moins égal au diamètre extérieur, à sa partie supérieure, du cône formé par la mâchoire 4 et un goujon fileté 13 solidarisé au plateau par des vis 17.As shown in Figure 3, the movable jaw 4 is disposed on the conical head 5 and conventionally rests, as shown in Figure 1, on the wide lower part of the conical head. Its tightening in this position is effected by means of a blocking element constituted by a two-part screw, a blocking plate 16 whose diameter is at least equal to the outside diameter, at its upper part, of the cone formed by the jaw 4 and a threaded stud 13 secured to the plate by screws 17.
Un cache de protection 23 des têtes des vis 17 est également prévu sur le plateau de blocage et fixé simplement sur celui-ci avec une vis.A protective cover 23 of the heads of the screws 17 is also provided on the blocking plate and simply fixed thereon with a screw.
Comme on l'a indiqué plus haut pour l'art antérieur, la rotation de la mâchoire 4, pendant le fonctionnement, par rapport à la tête 5, procure un auto serrage de la pièce 16, 13 et permet ainsi de maintenir un serrage adéquat malgré l'usure de la mâchoire.As indicated above for the prior art, the rotation of the jaw 4, during operation, relative to the head 5, provides a self-tightening of the part 16, 13 and thus makes it possible to maintain an adequate tightening despite the wear of the jaw.
Toutefois, en fonctionnement, lorsque la mâchoire 4 glisse sur la tête malgré le serrage important, elle glisse également par rapport au plateau de blocage 16 dans sa rotation. Celui-ci ne transmet alors le couple de rotation au goujon 13 par les vis 17 que partiellement.However, in operation, when the jaw 4 slides over the head despite the significant tightening, it also slides relative to the blocking plate 16 in its rotation. This then transmits the torque to the stud 13 by the screws 17 only partially.
Pour assurer la solidarisation de la mâchoire 4 et du plateau de blocage 16, des tenons 14 sont prévus sur la périphérie interne de la mâchoire 4 au niveau de son ouverture supérieure. Des encoches 15 de forme correspondante et en nombre égal sont pratiquées sur la périphérie du plateau de blocage 16. Encoches et tenons sont régulièrement répartis sur lesdites périphéries de manière à engrener les uns dans les autres.To secure the jaw 4 and the locking plate 16, pins 14 are provided on the internal periphery of the jaw 4 at its upper opening. 15 shaped notches corresponding and in equal number are formed on the periphery of the locking plate 16. Notches and tenons are regularly distributed over said peripheries so as to mesh with one another.
De cette manière, lors du fonctionnement du broyeur, une rotation de la mâchoire 4 va entraîner une rotation de l'élément de blocage 16 et un autoserrage du couple plateau de blocage 16 - goujon 13, donc un autoserrage de la mâchoire 4 sur la tête 5.In this way, during operation of the crusher, a rotation of the jaw 4 will cause a rotation of the locking element 16 and a self-tightening of the blocking plate 16 - stud 13 pair, therefore a self-tightening of the jaw 4 on the head. 5.
Le même système de tenons et encoches peut être appliqué au broyeur giratoire, pour solidariser l'écrou de serrage et la mâchoire.The same system of tenons and notches can be applied to the gyratory crusher, to secure the clamping nut and the jaw.
La figure 4 montre une coupe du système au niveau de l'ouverture du cône formant la mâchoire 4. Dans l'exemple représenté, quatre tenons et quatre encoches sont prévus. Mais il peut bien entendu être prévu un nombre de tenons et d'encoches inférieur ou supérieur. Figure 4 shows a section of the system at the opening of the cone forming the jaw 4. In the example shown, four studs and four notches are provided. But it can of course be provided a number of pins and notches lower or higher.
