Abstract

The invention relates to a device making it possible to break up, quietly and without showering, hard and compact materials in order to reduce the volume thereof and facilitate handling thereof. It is made up of a casing box 8 comprising a separation 11 connected to a carrier by the mounting plate 1. The orifices 2 allow the passage of supply hoses connected to the tools by the connectors 3 and 4. The rotary perforation assembly 5-7 and 15 runs on the rail 9 from top to bottom and vice versa guided by the tab 13 and leaves by the orifice 17 which allows it to bore into the material. The crushing (splintering) assembly 6 and 12 runs on the rail 10 from top to bottom and vice versa guided by the tab 14 and leaves by the orifice 18 in order to go and crush the material. The base of the housing 16 includes gripping studs. The device according to the invention is particularly intended for demolition of materials.

Description

La présente invention concerne un dispositif pour briser les matériaux rocheux ou du même type tel que béton, etc ... The present invention relates to a device for breaking rocky materials or of the same type such as concrete, etc.

L'éclatement et la dislocation du rocher sont traditionnellement et actuellement effectués à l'aide d'explosifs avec ses dangers, ses contraintes, sa kyrielle de consignes de sécurité et sa multitude de risques pour l'environnement ou à l'aide d'un brise roche hydraulique très bruyant, peu performant suivant la dureté de l'élément à débiter, onéreux en maintenance et d'un pouvoir stressant sur l'entre humain dès son utilisation en zone urbaine. The bursting and dislocation of the rock are traditionally and currently carried out using explosives with its dangers, its constraints, its myriad of safety instructions and its multitude of risks for the environment or using a Very noisy hydraulic rock breaker, not very efficient depending on the hardness of the element to be cut, expensive to maintain and has a stressful effect on human contact as soon as it is used in urban areas.

Le dispositif, selon l'invention permet de remédier à ces inconvénients, il s'adapte et utilise l'énergie produite par l'engin sur lequel il est monté ce qui lui confère une très large autonomie, sans toutefois le paralyser en cas de panne grave du porteur. The device according to the invention overcomes these drawbacks, it adapts and uses the energy produced by the machine on which it is mounted, which gives it a very large autonomy, without however paralyzing it in the event of a breakdown. serious of the wearer.

Il comporte en effet, selon une première vision un boîtier protecteur 8 s'adaptant sur divers engins, grâce à une platine 1 pourvue de trous de fixation. Cette platine 1 comprend deux orifices 2 permettant le passage des flexibles et leur branchement en 3 et 4. Le boîtier 8 comporte une séparation 11 en tôle forte servant de support et fixations au rail guide 9 assurant le chariotage du moteur hydraulique 5 donnant la rotation à la tige 7 et son taillant avec trous de soufflage 15. Une patte de centralisation 13 est également fixée sur la séparation 11. Un orifice 17 situé à l'embase 16 assure le passage de l'ensemble de perforation 7 et 15. It indeed comprises, according to a first vision a protective housing 8 adapting to various machines, thanks to a plate 1 provided with fixing holes. This plate 1 comprises two orifices 2 allowing the passage of the hoses and their connection at 3 and 4. The housing 8 comprises a partition 11 made of heavy sheet metal serving as support and fixings to the guide rail 9 ensuring the carriage of the hydraulic motor 5 giving the rotation to the rod 7 and its cutting edge with blowing holes 15. A centralization tab 13 is also fixed on the partition 11. An orifice 17 located at the base 16 ensures the passage of the perforation assembly 7 and 15.

Dans la seconde alvéole du boîtier 8, un rail guide 10 est fixé sur la séparation 11. Il assure la translation du chariot 6 et son vérin 12. Une patte de centralisation 14 assure le guidage du vérin 12 lors de sa sortie vers l'exté rieur grâce à l'orifice 18 situé dans l'embase à ergots 16. In the second cell of the housing 8, a guide rail 10 is fixed on the partition 11. It translates the carriage 6 and its jack 12. A centralization tab 14 guides the jack 12 when it exits to the outside laughing thanks to the orifice 18 located in the lug base 16.

Sur le boîtier 8 n'apparaît pas les trappes de visite et d'intervention qui seront judicieusement et efficacement positionnées lors de l'assemblage des éléments. On the housing 8 does not appear the inspection and intervention hatches which will be judiciously and effectively positioned during the assembly of the elements.

Dans un premier temps, après avoir fixé l'invention à l'aide de sa platine 1 sur le porteur, on appui l'ensemble sur le rocher par l'intermédiaire de son embase à ergots 16. Du poste de commande le conducteur actionne le moteur hydraulique 5 qui exécute la foration du rocher par l'intermédiaire de la tige 7 et son taillant 15. Ensuite on procède au nettoyage du trou par soufflage grâce aux trous destinés à cet usage dans le taillant 15. Ensuite on remonte l'ensemble de perforation grâce au rail guide 9. On déplace légèrement l'embase à ergots 16 et l'on procède à l'introduction du vérin 12 dans le trou exécuté grâce au passage 18 situé dans l'embase à ergots 16.Lorsque le vérin 12 est complètement descendu dans le trou, le conducteur du porteur actionne de la cabine la mise en pression du vérin 12, ce dernier par sa poussée latérale provoque la fissuration du rocher Fig 4. Firstly, after having fixed the invention using its plate 1 on the carrier, the assembly is supported on the rock by means of its lug base 16. From the control station, the driver actuates the hydraulic motor 5 which performs the drilling of the rock by means of the rod 7 and its cutting edge 15. Then the hole is cleaned by blowing through the holes intended for this use in the cutting edge 15. Then the assembly is reassembled. perforation thanks to the guide rail 9. The lug base 16 is moved slightly and the actuator 12 is introduced into the hole made through the passage 18 located in the lug base 16.When the actuator 12 is completely lowered into the hole, the driver of the carrier actuates the pressurization of the jack 12 from the cabin, the latter by its lateral thrust causes cracking of the rock Fig 4.

En effectuant la manoeuvre inverse on rétracte le vérin 12, il n'y a plus qu'à le sortir de son logement grâce au rail de chariotage 10. On lève l'embase à ergots 16 et l'on choisit un autre emplacement pour recommencer l'opération. By performing the reverse maneuver, the cylinder 12 is retracted, it only remains to remove it from its housing by means of the carriage rail 10. The lug base 16 is lifted and another location is chosen to start again. the operation.

Selon une variante non illustrée, on peut donner des impulsions par surpression ayant pour but de donner des à coups facilitant le travail du vérin 12 lorsque ce dernier est en pression maximale dans un élément très dur à casser. According to a variant not illustrated, pulses can be given by overpressure intended to give blows facilitating the work of the jack 12 when the latter is at maximum pressure in an element very hard to break.

Ces surpressions sont provoquées automatiquement et commandées directement par l'inteFmçdiaire du distributeur installé sur l'élément générateur. These overpressures are caused automatically and controlled directly by the intermediary of the distributor installed on the generator element.

Le dispositif selon l'invention est particulièrement destiné à réaliser une exploitation silencieuse et non dangereuse en milieu urbain. The device according to the invention is particularly intended for achieving silent and non-dangerous operation in an urban environment.
