Description
La présente invention est relative à un bras haveur sur lequel est tendu un élément sans fin garni extérieurement d'outils coupants destinés à exécuter le havage et l'abattage de roches et intérieurement de patins de guidage aptes à suivre une rainure ménagée le long dudit bras, l'élément sans fin étant entraîné en rotation par une roue motrice et une roue de renvoi présentant à leur périphérie des échancrures destinées à recevoir les patins de guidage susdits.The present invention relates to a lifting arm on which is stretched an endless element furnished externally with cutting tools intended to carry out the cutting and the felling of rocks and internally with guide shoes capable of following a groove formed along said arm. , the endless element being rotated by a drive wheel and a deflection wheel having at their periphery notches intended to receive the said guide pads.
On connaît déjà par le brevet européen n° 0014776 un bras haveur équipant une machine de havage de roches et comprenant un châssis bordé par des longerons aux extrémités desquels sont montées, respectivement une roue d'entraînement et une roue de renvoi d'un élément sans fin. Cet élément sans fin consiste généralement en une courroie portant extérieurement des outils coupants et intérieurement des patins de guidage constitués de blocs s'étendant dans une rainure. En service, les blocs glissent sur toute la largeur de la rainure sur une nappe de fluide amené à l'aide d'injecteurs ménagés au fond de la rainure. Dans les machines connues, les patins sont fixés sur la courroie à l'aide de vis traversant les courroies. L'inconvénient majeur de cette fixation consiste en un affaiblissement local de la courroie aux endroits de fixation puisque les trous de fixation constituent des discontinuités susceptibles d'induire des concentrations de contraintes de tension et de flexion.Already known from European Patent No. 0014776 a lifting arm equipping a rock cutting machine and comprising a chassis bordered by side members at the ends of which are mounted respectively a drive wheel and a return wheel of an element without end. This endless element generally consists of a belt externally carrying cutting tools and internally guide shoes consisting of blocks extending in a groove. In service, the blocks slide over the entire width of the groove on a sheet of fluid supplied using injectors formed at the bottom of the groove. In known machines, the pads are fixed to the belt using screws passing through the belts. The major drawback of this fixing consists in a local weakening of the belt at the fixing places since the fixing holes constitute discontinuities liable to induce concentrations of tension stresses and bending.
La roue motrice et la roue de renvoi comportent une âme pleine d'épaisseur uniforme et de pourtour circonférenciel garni d'un revêtement rugueux.The drive wheel and the return wheel have a solid core of uniform thickness and circumferential circumference provided with a rough coating.
En marche, les patins prennent appui sans glisser contre le revêtement rugueux de la roue motrice pour entraîner la courroie. Pour éviter le patinage des patins sur la roue motrice par manque d'adhérence, il est nécessaire de tendre au maximum la courroie entre la roue motrice et la roue de renvoi. Une telle précontrainte de traction entraîne bien sûr une usure prématurée de la courroie.When running, the pads press without sliding against the rough coating of the drive wheel to drive the belt. To avoid slipping of the pads on the drive wheel due to lack of grip, it is necessary to tension the belt as much as possible between the drive wheel and the idler wheel. Such tensile preload naturally leads to premature wear of the belt.
On connaît également par la demande de brevet allemand DE-A 3128264, un bras haveur d'une machine de havage de charbon comportant une courroie sans fin, de section trapézoïdale, garnie extérieurement d'éléments coupants diamantés et intérieurement de patins de guidage. La courroie est entraînée en rotation par une roue motrice et par une roue de renvoi munie d'une gorge trapézoïdale dont les parois inclinées enserrent les flancs de la courroie.Also known from German patent application DE-A 3128264 is a lifting arm of a coal cutting machine comprising an endless belt, of trapezoidal cross section, furnished externally with diamond cutting elements and internally with guide shoes. The belt is rotated by a drive wheel and by a return wheel provided with a trapezoidal groove whose inclined walls enclose the sides of the belt.
La courroie est munie sur sa face extérieure de créneaux sur lesquels sont fixés par emboîtement des éléments porte-outils fixés à l'aide de goupilles engagées dans des trous transversaux.The belt is provided on its outer face with slots on which are fixed by interlocking tool-holder elements fixed with pins engaged in transverse holes.
Cette configuration permet de reprendre entièrement les chocs considérables auquels sont soumises les têtes d'outils, à l'aide des surfaces d'appui prévues à cet effet entre la tête d'outil et le corps d'outil.This configuration makes it possible to fully absorb the considerable shocks to which the tool heads are subjected, using the bearing surfaces provided for this purpose between the tool head and the tool body.
Elle permet également d'éviter l'endommagement des goupilles de fixation, de manière sûre.It also prevents damage to the fixing pins, in a safe way.
L'inconvénient majeur de ce bras haveur connu réside dans le fait que la courroie est soumise à des flexions importantes et répétées aux extrémités de chacun des patins, lors de chaque passage sur les roues motrices et de renvoi. Ces flexions répétées entraînent la fatigue localisée de la courroie et provoquent la rupture progressive de celle-ci.The major drawback of this known lifting arm lies in the fact that the belt is subjected to significant and repeated bending at the ends of each of the pads, during each passage on the drive and return wheels. These repeated flexions cause localized fatigue of the belt and cause it to rupture progressively.
Enfin, un bras haveur est connu de BE-A-865189 sur lequel est tendu un élément sans fin entraîné en rotation par une roue motrice et une roue de renvoi et équipé extérieurement d'outils coupants destinés à exécuter le havage et l'abattage des roches et intérieurement de patins de guidage aptes à suivre une rainure ménagée le long dudit bras. La roue motrice présente à sa périphérie des échancrures dans lesquelles engrènent les patins.Finally, a lifting arm is known from BE-A-865189 on which is stretched an endless element driven in rotation by a driving wheel and a deflection wheel and externally equipped with cutting tools intended to carry out the cutting and the felling of rocks and internally guide shoes able to follow a groove formed along said arm. The drive wheel has notches at its periphery in which the pads mesh.
L'inconvénient majeur de ce bras haveur connu réside dans le fait que les échancrures sont peu profondes et que les patins reposent sur le fond des échancrures. La traction exercée sur l'élément sans fin par la roue motrice et la roue de renvoi est entièrement reprise à travers les patins de guidage, de sorte que des forces de pliage importantes et répétées sont appliquées sur l'élément sans fin aux extrémités de chacun des patins, à cause des couples transmis par ceux-ci.The major drawback of this known lifting arm lies in the fact that the notches are shallow and that the pads rest on the bottom of the notches. The traction exerted on the endless element by the drive wheel and the deflection wheel is fully taken up through the guide shoes, so that significant and repeated bending forces are applied to the endless element at the ends of each. skates, because of the couples transmitted by these.
Par le document US-A-3604755, on connaît un bras haveur comprenant une roue motrice et une roue de renvoi qui sont pourvues d'échancrures à flancs inclinés et sur lesquelles est tendue une chaîne sans fin dont les maillons sont formés de patins trapézoïdaux qui suivant une rainure ménagée le long du bras et qui engrènent dans les échancrures susdites en reposant sur les flancs inclinés des échancrures. Une telle chaîne sans fin est bruyante en raison du martellement de la roue motrice et de la roue de renvoi par les patins.Document US-A-3604755 discloses a lifting arm comprising a drive wheel and a drive wheel. return which are provided with notches with inclined sides and on which is stretched an endless chain whose links are formed by trapezoidal shoes which follow a groove formed along the arm and which mesh in the aforementioned notches by resting on the inclined sides of the indentations. Such an endless chain is noisy due to the hammering of the drive wheel and the return wheel by the pads.
La présente invention vise à remédier aux inconvénients susdits. Elle est relative à une haveuse comportant un bras haveur sur lequel est tendu un élément sans fin équipé extérieurement d'outils coupants destinés à exécuter le havage et l'abattage de roches et intérieurement de patins de guidage aptes à suivre une rainure ménagée le long dudit bras, l'élément sans fin étant entraîné en rotation par une roue motrice et une roue de renvoi présentant à leur périphérie, des crêtes séparées par des échancrures destinées à recevoir les patins de guidage susdits.The present invention aims to remedy the above drawbacks. It relates to a shearer comprising a shearer arm on which is stretched an endless element equipped externally with cutting tools intended to carry out the havage and the felling of rocks and internally with guide shoes able to follow a groove formed along said arm, the endless element being driven in rotation by a drive wheel and a return wheel having at their periphery, ridges separated by notches intended to receive the aforementioned guide pads.
Selon l'invention, l'élément sans fin prend appui sur les crêtes, de manière à éviter tout contact des patins de guidage contre les roues (8,9).According to the invention, the endless element bears on the ridges, so as to avoid any contact of the guide pads against the wheels (8, 9).
Dans une forme de réalisation préférée, l'élément sans fin est une courroie crantée.In a preferred embodiment, the endless element is a toothed belt.
Les crêtes séparant les échancrures susdites des roues motrice et de renvoi, sont garnies de dents qui engrènent dans les crénelures correspondantes de la courroie crantée, en y prenant appui de manière à éviter tout contact des patins de guidage contre les roues.The ridges separating the aforementioned notches from the drive and deflection wheels are furnished with teeth which mesh in the corresponding notches of the toothed belt, bearing thereon so as to avoid any contact of the guide pads against the wheels.
Suivant une particularité de l'invention la face supérieure du support de patin présente des évidements destinés à recevoir les crénelures d'une courroie crantée.According to a feature of the invention, the upper face of the pad support has recesses intended to receive the crenellations of a toothed belt.
Dans une forme de réalisation particulière, la partie inférieure du corps d'outil en métal porte une semelle éventuellement amovible en matière synthétique.In a particular embodiment, the lower part of the metal tool body carries an optionally removable sole made of synthetic material.
D'autres particularités et détails de l'invention apparaîtront au cours de la description détaillée suivante faisant référence aux dessins ci-annexés et qui représentent schématiquement et à titre non limitatif, une forme de réalisation du dispositif suivant l'invention.Other features and details of the invention will appear during the following detailed description referring to the attached drawings and which schematically and without limitation, an embodiment of the device according to the invention.

Les dents engrènent dans les crénelures 21 de la courroie crantée et forcent celle-ci à adhérer à la roue motrice en excluant tout patinage.The teeth mesh in the
Cette disposition a l'avantage de transmettre le couple de traction à la courroie par l'intermédiaire de l'ensemble des fibres voisines des fibres principales de la courroie crantée et non pas par l'intermédiaire des patins. On augmente ainsi la durée de vie de la courroie.This arrangement has the advantage of transmitting the traction torque to the belt by means of all of the fibers adjacent to the main fibers of the toothed belt and not by means of the pads. This increases the life of the belt.
