Description

"REDUTOR BLINDADO ACIONADO ATRAVÉS DE COROA E PINHÃO COMANDADO POR MOTOR ELÉTRICO/HIDRÁULICO COM SUPORTE PARA SUSTENTAÇÃO DE PNEUTORQUE".  "SHIELD REDUCER DRIVEN THROUGH CROWN AND PINION CONTROLLED BY ELECTRIC / HYDRAULIC MOTOR WITH SUPPORT FOR PNEUTORQUE SUPPORT".
Refere-se a presente patente de invenção a um "REDUTOR BLINDADO ACIONADO ATRAVÉS DE COROA E PINHÃO COMANDADO POR MOTOR ELÉTRICO/HIDRÁULICO COM SUPORTE PARA SUSTENTAÇÃO DE PNEUTORQUE", que foi desenvolvido para equipar válvulas angulares de aita pressão e altas temperaturas permitindo uma abertura e fechamento rápidos, seja através do motor ou através do pneutorque, com total segurança ao operador com acionamento através de coroa e pinhão.  This patent relates to a "DRIVEN BLOCKED REDUCER THROUGH ELECTRIC / HYDRAULIC MOTOR CONTROLLED WITH PNEUTORQUE SUSTAINING SUPPORT", which has been developed to equip high pressure and high temperature angled valves for opening and quick closing, either through the motor or through the tire, with total operator safety with crown and pinion drive.
Os redutores comumente utilizados em válvulas de alta pressão empregadas em tubulações condutoras, principalmente de polpa de bauxita com mistura cáustica e cal, com temperatura elevada para a extração de aluraina, são em sua totalidade isentas de uma blindagem protetora, o que tem gerado muitos acidentes com os operadores devido ao vazamento do liquido contido na tubulação quando da necessidade de reparos.  The reducers commonly used in high pressure valves used in conductive piping, mainly caustic mixture of bauxite pulp and lime, with high temperature for the extraction of alurain, are entirely free of protective shielding, which has caused many accidents. with operators due to leaking liquid contained in the pipeline when repairs are required.
Outro inconveniente encontrado nesses redutores está relacionado à falta de concentricidade do seu eixo longitudinal em relação à válvula, pois este trabalha inserido era uma bucha a qual, devido ao seu desgaste durante o trabalho forçado e por não possuir um sistema de ajuste, se torna excêntrica em relação à válvula, o que impede um perfeito funcionamento da mesma.  Another drawback found in these gear units is related to the lack of concentricity of its longitudinal axis in relation to the valve, because this inserted work was a bushing which, due to its wear during forced work and not having an adjustment system, becomes eccentric in relation to the valve, which prevents its perfect functioning.
Outro ponto que devemos destacar está relacionado ao fechamento das válvulas a partir do redutor quando da ocorrência de pane no motor elétrico e sem a necessidade de se utilizar o pneutorque, ocorre que estes redutores não possuem um suporte de sustentação para o posicionamento deste equipamento, obrigando o operador a promover o fechamento da válvula segurando o pneutorque com os braços até o fechamento total da válvula, ocorre que este equipamento possui um peso especifico elevado e sua disposição construtiva não permite uma boa empunhadura, além do fechamento da válvula, em muitos casos, levar horas, o que torna o serviço lento e laborioso e impede que o operador desenvolva outra função, necessitando, muitas vezes, de vários operários para este serviço. Another point that should be highlighted is related to the closing of the valves from the gear unit when the electric motor fails and without the need to use the tire, it occurs that these gear units do not have a support for the positioning of this equipment, forcing the operator to close the valve by holding the tire with the arms until the valve is fully closed, this equipment has a high specific weight and its constructive arrangement does not allow a good grip, besides the valve closing In many cases, it takes hours, which makes the service slow and laborious and prevents the operator from performing another function, often requiring several workers for this service.
Diante deste e outros não mencionados inconvenientes, o inventor desenvolveu o "REDUTOR BLINDADO ACIONADO ATRAVÉS DE COROA E PINHÃO COMANDADO POR MOTOR ELÉTRICO/HIDRÁULICO COM SUPORTE PARA SUSTENTAÇÃO DE PNEUTORQUE" compreendido por um corpo principal formado a partir de uma caixa que acondiciona em seu interior uma coroa, esta movida por um pinhão fixado a um eixo de comando do redutor acionado através de um motor elétrico/hidráulico, um volante de operação, ou um pneutorque, que na secção frontal incorpora um suporte, sendo que a dita coroa está apoiada sobre rolamento cónico de ajuste, enquanto sua secção superior detém uma porca de travamento fixada através de parafusos que permitem o ajuste da bucha centralizadora, esta acoplada centralmente na dita coroa, bucha esta que detém externamente em sua secção inferior um rolamento cónico de ajuste e recebe ainda o acoplamento do eixo longitudinal de esmerilhamento cujo extremo recebe um volante de comando abaixo do qual verifica-se uma trava porca, sendo que o dito eixo de comando do redutor na face interna da caixa detém uma porca trava e está apoiado em rolamentos de ajuste horizontais, estes lacrados através de uma tampa de rolamento comprimida através de porca trava e contra porca trava, sendo que a dita caixa externamente proteja uma haste de travamento e uma tampa lacra, enquanto o eixo de comando do redutor é ladeado por furos para acoplamento do suporte de sustentação, este fixado através de corrente na haste de travamento. Faced with this and others not mentioned drawbacks, the inventor developed the "ARMORED DRIVE THROUGH CROWN AND HYDRAULIC ENGINE CONTROLLED WITH SUPPORT FOR PNEUTORQUE SUPPORT" comprised of a main body formed from a box inside it a crown is driven by a pinion mounted to a gearbox drive shaft driven by an electric / hydraulic motor, an operating flywheel, or a pneumoque, which incorporates a support in the front section, said crown being supported by while its upper section holds a locking nut fixed by screws that allow the adjustment of the centering bushing, it is centrally coupled to said crown, which bushing externally holds a adjusting tapered bearing and also receives the coupling of the grinding longitudinal axis whose end receives a steering wheel below of which a locking nut occurs, said reducer camshaft on the inner face of the housing having a locking nut and being supported by horizontal adjusting bearings, which are sealed by means of a bearing cover compressed by locking nut and against lock nut, and said box externally secure a locking rod and a sealing cap, while the reducer camshaft is flanked by holes for coupling the support bracket, which is secured by chain to the locking rod.
Para que sé possa obter uma perfeita compreensão do que fora desenvolvido, são apensos desenhos ilustrativos aos quais far-se-ão referências numéricas em conjunto com uma descrição pormenorizada, onde a:  In order to gain a perfect understanding of what has been developed, illustrative drawings are attached to which numerical references will be made together with a detailed description, where:

Como inferem os desenhos e em seus pormenores, podemos observar que o "REDUTOR BLINDADO ACIONADO ATRAVÉS DE COROA E PINHÃO COMANDADO POR MOTOR ELÉTRICO/HIDRÁULICO COM SUPORTE PARA SUSTENTAÇÃO DE PNEUTORQUE" caracterizado por um corpo principal ( 1 ) formado a partir de uma caixa (2) que acondiciona em seu interior (3) uma coroa (4), esta movida por um pinhão (5) fixado a um eixo de comando do redutor (6) acionado através de um motor elétrico/hidráulico (7), um volante ( 16) de operação ou um pneutorque (8) que na secção frontal (9) incorpora um suporte ( 10), sendo que a dita coroa (4) está apoiada sobre rolamento cónico de ajuste ( 1 1 ), enquanto sua secção superior detém uma porca de travamento (12) fixada através de parafusos (13) que permitem o ajuste da bucha centralizadora ( 14), esta acoplada centralmente na dita coroa (4), bucha (13) esta que detém externamente em sua secção inferior ( 15) um rolamento cónico ( 1 1 ) de ajuste e recebe ainda o acoplamento do eixo longitudinal de esmerilhamento (18) cujo extremo recebe um volante de comando ( 19) abaixo do qual verifica-se uma trava porca (20), sendo que o dito eixo de comando do redutor (6) na face interna da caixa (2) detém uma porca trava (21 ) e está apoiado em rolamentos de ajuste horizontais (22), estes lacrados através de uma tampa de rolamento (23) comprimida através de porca trava (21 ) e contra porca trava (24) sendo que a dita caixa (2) externamente proteja uma haste de travamento (25) e uma tampa lacra (26), enquanto o eixo de comando do redutor (6) é ladeado por furos para acoplamento do suporte de sustentação (27), este fixado através de corrente (28) na haste de travamento (25). As the drawings and their details show, we can see that the "ARMORED DRIVER THROUGH CROWN AND PINION CONTROLLED BY ELECTRIC / HYDRAULIC MOTOR WITH SUPPORT FOR PNEUTORQUE SUPPORT" characterized by a main body (1) formed from a housing ( 2) which houses inside it (3) a crown (4), it is driven by a pinion (5) fixed to a drive shaft of the gearbox (6) driven by an electric / hydraulic motor (7), a flywheel ( 16) or a tire (8) which in the front section (9) incorporates a support (10), said crown (4) being supported by a tapered adjustment bearing (11), while its upper section holds a locking nut (12) fixed by bolts (13) allowing adjustment of the centering bushing (14), it is centrally coupled to said crown (4), bushing (13) which externally holds in its lower section (15) a tapered roller bearing (11) and further receives coupling of the longitudinal grinding axis (18) whose end receives a steering wheel (19) below which there is a lock nut (20), said reducer drive shaft (6) on the inner face of the housing (2) has a lock nut (21) and is supported by horizontal adjustment bearings (22), these sealed by means of a bearing cap (23) compressed by a lock nut (21) and against a lock nut (24), said housing (2) externally protecting a locking rod (25) and a sealing cap (26), while the drive shaft of the gear unit (6) is flanked by holes for coupling the support bracket (27), it is fixed by chain (28) to the locking rod (25).
Com base no descrito e ilustrado é dado a perceber que o "REDUTOR BLINDADO ACIONADO ATRAVÉS DE COROA E PINHÃO COMANDADO POR MOTOR ELÉTRICO/HIDRÁULICO COM SUPORTE PARA SUSTENTAÇÃO DE PNEUTORQUE" pode ser acionado por três elementos distintos: por um motor elétrico/hidráulico; por pneutorque, através de ar comprimido; ou manualmente, através de um volante utilizado na falta de energia elétrica, volante este extraído do eixo longitudinal de esmerilhamento e plugado no eixo de comando do redutor.  Based on what is described and illustrated, it is understood that the "Shielded Shield Reducer Driven Through Crown / Pinion Controlled by Electric / Hydraulic Motor Supported to Support Pneumatic" can be driven by three distinct elements: by an electric / hydraulic motor; by pneumoque, through compressed air; or manually, by means of a flywheel used in the absence of electricity, this flywheel is extracted from the longitudinal grinding axis and plugged into the control shaft of the gear unit.
Devemos ressaltar que o rolamento disposto interiormente na bucha permite um melhor giro e perfeito esmerilhamento da válvula e impede que a bucha toque no castelo, sendo que o rolamento superior impede que tal bucha seja deslocada do eixo principal aumentando a vida útil do equipamento, além de contar com uma porca de travamento vertical que permite seu ajuste em relação à coroa que juntamente com o rolamento superior impede seu deslocamento do centro de giro. Podemos destacar ainda que a utilização de rolamentos de ajustes horizontais que apoiam o eixo de comando do redutor impedem sua excentricidade aumentando a suavidade do movimento de rotação. It should be noted that the bearing arranged internally on the bushing allows a better turning and perfect grinding of the valve and prevents the bushing from touching the bonnet, while the upper bearing prevents such bushing from being displaced from the mainshaft, increasing the service life of the equipment. It has a vertical locking nut that allows its adjustment in relation to the crown that together with the upper bearing prevents its displacement of the center of rotation. We can also highlight that the use of horizontal adjustment bearings that support the drive shaft of the gearbox prevent its eccentricity increasing the smoothness of the rotational movement.
Outra grande vantagem encontrada no equipamento está relacionada ao suporte de sustentação do pneutorque, pois a inclusão desse dispositivo permite que o mesmo trabalhe sem a necessidade de ser sustentado pelo operador, permitindo que após o serviço executado seja removido e fique preso a própria caixa do redutor através de corrente, com isso evita-se acidentes e o esforço desnecessário do operador que fica liberado para outras atividades.  Another great advantage found in the equipment is related to the tire support bracket, because the inclusion of this device allows it to work without the need to be supported by the operator, allowing after the service performed to be removed and the gearbox housing itself is stuck. through current, this avoids accidents and unnecessary operator effort that is released for other activities.
Vale lembrar ainda que com o acionamento da trava porca permite que o eixo longitudinal passe a girar louco facilitando o esmerilhamento interno da válvula para retirada do material incrustado em seu interior e, consequentemente, diminuindo o esforço físico do operador.  It is also worth remembering that the actuation of the lock nut allows the longitudinal axis to turn crazy, facilitating the internal grinding of the valve to remove the embedded material inside and, consequently, reducing the physical effort of the operator.
O redutor ora reivindicado possui uma disposição inovadora em seu aspecto geral, pois além das vantagens acima descritas conta ainda com uma caixa de redutor totalmente blindada que impede a ocorrência de acidentes, por ser inovador e até então não compreendidas no estado da técnica que enquadra-se perfeitamente dentro dos critérios que definem a patente de invenção. São as seguintes suas reivindicações.  The gear unit now claimed has an innovative layout in its general aspect, as in addition to the advantages described above it also has a fully shielded gearbox that prevents accidents, since it is innovative and hitherto not understood in the state of the art. perfectly within the criteria defining the invention patent. The following are their claims.
