Abstract

Several elastomer straps (3) lined with sliding inserts (5) with a low coefficient of friction are placed under the U shaped conveyor belt (2) at the point of loading. The straps are supported on metal supports (6) by means of hooks (4). The width, thickness and hardness of the straps can vary according to impact forces of the transported products. The sliding inserts are engaged in holes in the strap so that the elastomer can deform lengthways. Under the effect of shocks the belt is supported on the inserts, which in turn are supported by the elastomer strap, and absorb and limit the deformation of the belt.

Description

"SANGLE AMORTISSEUSE DE CHOCS POUR COURROIE DE CONVOYEUR"
I - DESCRIPTION
1-1 Sangle en élastomère garnie d'inserts de glissement à faible coefficient de frottement, destinée à soutenir la courroie d'un convoyeur."SHOCK ABSORBER STRAP FOR CONVEYOR BELT"
I - DESCRIPTION
1-1 Elastomer strap with sliding inserts with low friction coefficient, intended to support the belt of a conveyor.

Plusieurs de ces sangles placées sous la courroie formée en auge, au point de chargement, constituent un dispositif amortisseur des chocs importants engendrés par la chute des produits transportés.Several of these straps placed under the belt formed in a trough, at the loading point, constitute a device for absorbing large shocks caused by the fall of the products transported.

1-2 Btat actuel de la technique
Les produits en vrac, transportés à l'aide de convoyeur à courroie sont déposés sur celle-ci, formée en auge en un point qui peut être fixe ou mobile nommé point de chargement".1-2 Current state of the art
The bulk products, transported using a belt conveyor, are deposited on the latter, formed in a trough at a point which can be fixed or mobile, called loading point ".

La chute des produits en ce point engendre parfois des chocs qui peuvent être nuisibles à la courroie.The fall of the products at this point sometimes generates shocks which can be harmful to the belt.

Pour limiter les sollicitations de la courroie, on utilise plusieurs systèmes - les rouleaux amortisseurs (rouleaux en acier garnis de caoutchouc) - Barres d'impact (barres en élastomère revêtues d'un matériaux glissant) disposées longitudinalement par rapport à la courroie.To limit the stresses on the belt, several systems are used - the shock absorbing rollers (rubber-coated steel rollers) - Impact bars (elastomer bars coated with a sliding material) arranged longitudinally relative to the belt.

- Plateaux de réception en matière plastique glissante supportés par des amortisseurs en caoutchouc. - Sliding plastic receiving trays supported by rubber shock absorbers.

1-3 Exposé de l'invention
La sangle amortisseuse est constituée par un ruban en élastomère dont la largeur, l'épaisseur et la dureté peuvent varier en fonction de l'amortissement recherché
Largeur, épaisseur et dureté sont déterminées pour obtenir une sangle telle que les efforts d'impact des produits transportés se traduisent par un allongement de ltélastomère. 1-3 Presentation of the invention
The shock-absorbing strap is made up of an elastomer ribbon, the width, thickness and hardness of which can vary depending on the desired cushioning
Width, thickness and hardness are determined to obtain a strap such that the impact forces of the products transported result in an elongation of the elastomer.

Le glissement de la courroie est assuré par des inserts en matériau glissant dont le nombre, la surface et 1' im- plantation peuvent varier en fonction du problème à traiter.The sliding of the belt is ensured by inserts of sliding material, the number, surface and location of which may vary according to the problem to be treated.

Les inserts de glissements sont intégrés à la sangle par tout moyen permettant à l'élastomère de se déformer pour jouer son rôle amortisseur.The slip inserts are integrated into the strap by any means allowing the elastomer to deform to play its damping role.

La sangle est supportée par des supports métalliques appropriés, réalisés pour se substituer aux supports de rouleaux amortisseurs classiques.The strap is supported by suitable metal supports, made to replace the supports of conventional shock absorbing rollers.

La sangle est fixée aux supports par des crochets métalliques dont l'extrémité est noyée dans l'élastomère ou par des bridages mécaniques.The strap is fixed to the supports by metal hooks, the end of which is embedded in the elastomer or by mechanical clamps.

Un point de chargement peut comporter plusieurs sangles implantées transversalement par rapport à l'axe de déplacement de la courroie.A loading point can have several straps located transversely to the axis of movement of the belt.

Les sangles peuvent être rapprochées les unes des autres pour former un tapis support continu.The straps can be brought together to form a continuous support mat.

1-5 Exposé détaillé
La courroie 2 mise en mouvement par son tambour d'entrainement, glisse sur les inserts 5 intégrés dans la sangle en élastomère 3.1-5 Detailed presentation
The belt 2 set in motion by its drive drum, slides on the inserts 5 integrated in the elastomer strap 3.

Les sangles (en général au nombre de 3) sont supportées par les supports 6 par l'intermédiaire des crochets 4.The straps (generally 3 in number) are supported by the supports 6 by means of the hooks 4.

Les inserts en matériau glissant 5 sont engagés dans des perforations adéquates de la sangle 3 de telle sorte que ltélastomère puisse se déformer par allongement.The inserts of sliding material 5 are engaged in suitable perforations of the strap 3 so that the elastomer can deform by elongation.

Les crochets 4 sont noyés dans la sangle en élastomère lors de son moulage.The hooks 4 are embedded in the elastomer strap during its molding.

Sous l'effet des chocs dirigés selon la flêche 1, la courroie s'appuie sur les inserts 5 supportés par la sangle en élastomère qui amortie et limite la déformation de la courroie par son allongement.Under the effect of the shocks directed according to the arrow 1, the belt rests on the inserts 5 supported by the elastomer strap which absorbs and limits the deformation of the belt by its elongation.

1-6 Application industrielle
Amortissement des chocs engendrés par le poids, la granulométrie et la hauteur de chute des produits en vrac chargés sur les courroies des convoyeurs.1-6 Industrial application
Damping of the shocks generated by the weight, the grain size and the fall height of the bulk products loaded on the conveyor belts.

Influence bénéfique sur la durée de vie des courroies.Possibilité d'utilisation comme support courant de courroie en auge.Beneficial influence on the lifespan of belts.Possibility of use as a current support for tread belts.

Application dans les mines, carrières, sidérurgie, travaux publics etc... Application in mines, quarries, steel industry, public works etc ...
