Description

ACOPLADEIRA FLEXÍVEL E MÉTODO DE ACOPLAMENTO  FLEXIBLE COUPLER AND COUPLING METHOD
A Acopladeira Flexível se refere a um tipo de ferramenta para a área de montagem de tubulações industriais. Este dispositivo tem a função de auxiliar a montagem e o acoplamento entre os tubos, seus acessórios e conexões.  Flexible Coupler refers to a type of tool for the industrial piping assembly area. This device has the function of assisting the assembly and coupling between the pipes, their fittings and connections.
Um acoplamento para tubulação é qualquer tipo de encaixe ou dispositivo usado para unir dois ou mais tubos de tal modo que a continuidade seja mantida entre eles. Eles podem ser rígidos ou flexíveis, dependendo da quantidade de movimento de que o tubo é submetido e podem ser construídos com materiais permanentes ou removíveis;.  A pipe coupling is any type of fitting or device used to join two or more pipes such that continuity is maintained between them. They can be rigid or flexible, depending on the amount of movement that the tube undergoes and can be constructed with permanent or removable materials.
A maioria das instalações tubulares exige que vários comprimentos de tubos sejam unidos ou cortados para facilitar as mudanças de direção e travessias de obstáculos. Isto requer um método rápido de ligação entre as seções enquanto mantém a integridade dos tubos durante o processo. Estes acoplamentos podem ser permanentes por natureza, ou, se possível, eles podem ser desmontados, quando desejado. O acoplamento permanente geralmente faz uso de soldagem, no caso de aço ou de tubos de cobre; nos adesivos, é utilizado o PVC. Essas articulações permanentes, se instaladas corretamente, oferecem excelente rigidez e boas características de vedação, onde não há mudanças futuras previstas na tubulação. Os acoplamentos removíveis são muitas vezes desenhados com rosca, o que lhes permite serem aparafusados aos tubos e ainda poderem ser unidos.  Most tubular installations require multiple pipe lengths to be joined or cut to facilitate direction changes and obstacle crossings. This requires a quick method of bonding between sections while maintaining pipe integrity during the process. These couplings may be permanent in nature, or if possible they may be disassembled as desired. Permanent coupling usually makes use of welding in the case of steel or copper pipes; In the adhesives, PVC is used. These permanent joints, if properly installed, offer excellent rigidity and good sealing characteristics where no future piping changes are anticipated. Removable couplings are often threaded, which allows them to be bolted to the pipes and can still be joined.
Os acoplamentos para tubos podem também incluir outros recursos, como inspeção ou pontos de acesso de manutenção. Medidores de vazão e outros dispositivos são frequentemente construídos em um tubo de acoplamento para facilitar a instalação.  Pipe couplings may also include other features such as inspection or maintenance access points. Flowmeters and other devices are often built into a coupling pipe for ease of installation.
As acopladeiras são usadas na indústria, em geral, em que o acoplamento entre o tubo e seus acessórios é uma demanda permanente. Em muitas situações, é um componente muito importante da estrutura não padronizada.  Couplers are used in industry in general where coupling between the pipe and its fittings is a permanent demand. In many situations, it is a very important component of the non-standard structure.
Em busca realizada nos bancos de patentes identificou-se algumas patentes referentes a elementos dessa tecnologia, porém bastante diferentes da tecnologia que se apresenta. Por exemplo, a patente PI0804046-0 apresenta um acoplamento com um sistema de fixação realizado por encaixe e pressão de seus componentes. O sistema de fixação se caracteriza por uma peça central ou flanges com rasgos, cubos metálicos com fendas e perfis conectores. Anéis de aperto são usados para fixação na estrutura por pressão. Já a patente PI0516403-6 descreve um dispositivo de acoplamento para tubulações de fluido que compreende uma bucha, uma carcaça e um conector de acoplamento. A carcaça possui uma rosca externa que permite a ligação a uma tubulação de continuação ou a um equipamento a ser conectado. A search carried out in the patent banks identified some patents referring to elements of this technology, but quite different from the technology presented. For example, patent PI0804046-0 discloses a coupling with a clamping system performed by snapping and pressing of its components. The clamping system is characterized by a centerpiece or slotted flanges, slotted metal hubs and connector profiles. Clamping rings are used for fastening to the frame by snap. PI0516403-6 discloses a fluid pipe coupling device comprising a bushing, a housing and a coupling connector. The housing has an external thread that allows connection to a continuation piping or equipment to be connected.
A patente ΡΙ0 16175-0, por sua vez, descreve um acoplamento para fazer a ligação entre tubos alinhados e para prevenir que eles sejam separados, que compreende um par de luvas anulares e um dispositivo de aperto com flanges e parafusos de tração com porcas para tencionar o acoplamento. Já a patente PI021 785-1 apresenta um acoplamento para conectar uma tubulação a um flange de forma vedada. O acoplamento compreende uma gaxeta, um anel de montagem e um flange de montagem.  160 16175-0, in turn, discloses a coupling for connecting aligned pipes and preventing them from being separated, which comprises a pair of annular sleeves and a flanged clamping device and nut pull bolts. intend the coupling. PI021 785-1 discloses a coupling for connecting a pipe to a sealed flange. The coupling comprises a gasket, a mounting ring and a mounting flange.
Estes dispositivos, descritos acima, apresentam limitações na montagem para o acoplamento dos tubos e não são capazes de realizar a função da ferramenta acopladeira descrita na presente patente.  These devices, described above, have mounting limitations for pipe coupling and are not capable of performing the coupling tool function described in the present patent.
Há ainda, um dispositivo apresentado na patente US6076724, que descreve uma ferramenta para alinhamento e fixação de tubos que utiliza uma corrente ou um cabo e grampos de ajuste. Este dispositivo é o que mais se assemelha ao apresentado nesta patente, porém apresenta várias diferenças e desvantagens. Este dispositivo utiliza uma corrente ou um cabo já existente no mercado como suporte para os grampos de ajuste, gerando uma sobra para diferentes diâmetros da tubulação. Alem disso, para se fixar a corrente ou o cabo, o grampo possui uma abertura por onde a mesma passa e um pequeno parafuso que mantém o grampo na posição desejada. Se houver a necessidade de mudar o ponto de ajuste, deve-se afrouxar a corrente ou o cabo. Caso haja a necessidade de se acrescentar mais grampos, deve-se desmontar o acoplamento, adicionar um novo grampo e depois reposicioná-los novamente, aumentando o tempo de trabalho. Para solucionar estes problemas são utilizadas presilhas especialmente desenvolvidas para formar uma cinta flexível que se ajusta a tubulação, podendo ser adicionadas ou removidas de acordo com o diâmetro da tubulação, evitando-se a necessidade de desmontar o acoplamento para adicionar grampos e também se evitando a sobra da corrente ou cabo. There is also a device disclosed in US6076724, which describes a pipe alignment and fixing tool using a chain or cable and adjusting clamps. This device most closely resembles that disclosed in this patent, but has several differences and disadvantages. This device uses a commercially available chain or cable as support for the adjusting clamps, generating a surplus for different pipe diameters. In addition, to secure the chain or cable, the clamp has an opening through which it passes and a small screw that holds the clamp in the desired position. If there is a need to change the setpoint, loosen the chain or cable. Should additional clamps need to be added, the coupling must be disassembled, a new clamp added and then repositioned again, increasing working time. To solve these problems Specially designed clips are used to form a flexible strap that fits the pipe and can be added or removed according to the pipe diameter, avoiding the need to disassemble the coupling to add clamps and also to avoid excess chain or cable.
Outro importante problema detectado nessa tecnologia é que o dispositivo utiliza grampos confeccionados a partir de chapas dobradas e o parafuso de ajuste é do tipo borboleta, sendo que dessa maneira a ponta do mesmo danifica a superfície de contato com o tubo. No novo dispositivo, aqui descrito, são usados parafusos de alta resistência com ponta anti-rotacional que não danifica a tubulação. Outra vantagem apresentada pela nova acopladeira está no fato de se utilizar pino-trava em todos os grampos, para segurança no manuseio e transporte.  Another important problem detected in this technology is that the device uses clamps made from bent plates and the adjusting screw is of the butterfly type, thus the tip of the same damages the contact surface with the tube. In the new device described here, high strength bolts with anti-rotational tip that do not damage the tubing are used. Another advantage presented by the new coupler is that it uses a lock pin in all clamps for safe handling and transportation.
Verifica-se, portanto que as tecnologias atualmente utilizadas apresentam sérios problemas e deficiências, tais como: são de difícil manipulação, são pesadas, são descartadas após o uso, gastam maior tempo para execução do acoplamento, além de não serem capazes de desovalizar a tubulação, o que é possível com a nova tecnologia proposta nesta patente.  Therefore, the technologies currently used present serious problems and deficiencies, such as: they are difficult to handle, they are heavy, they are discarded after use, they spend more time to perform the coupling, and they are not able to de-energize the piping. , which is possible with the new technology proposed in this patent.
Assim, o estado da técnica apresenta no que se refere a Acopladeira Flexível, problemas de natureza económica, de segurança, de recursos humanos, de manutenção, de otimização do processo e das peças utilizadas, dentre outros. Tais problemas são solucionados pela nova tecnologia, objeto da presente patente.  Thus, the state of the art presents with regard to Flexible Coupler, economic, safety, human resources, maintenance, process optimization and parts problems, among others. Such problems are solved by the new technology, object of the present patent.

Na presente invenção descreve-se uma acopladeira flexível para montagem de tubos, ajustável, precisa e resistente com vantagens sobre o estado da técnica, uma vez que além de sanar os problemas existentes ela atende a demanda dos usuários no sentido de facilitar a fabricação, montagem e o ajuste de tubulações industriais.  The present invention describes an adjustable, precise and durable flexible pipe mounting coupler with advantages over the state of the art, since in addition to remedying existing problems it meets the demand of users to facilitate fabrication, assembly and the fitting of industrial pipes.
Esta acopladeira é composta, de forma não limitante, por presilhas (1), conectadas entre si por parafusos ou pinos-trava, especialmente desenvolvidas para formar uma cinta flexível que se ajusta à tubulação (2), podendo ser adicionadas ou removidas de acordo com o diâmetro da tubulação (2). Os pinos-trava não possuem rosca, podendo ser facilmente removidos para retirar ou acrescentar as presilhas (1), ajustando a ferramenta ao diâmetro da tubulação.  This coupler is made, without limitation, by clamps (1), connected to each other by bolts or locking pins, specially developed to form a flexible strap that fits the pipe (2) and can be added or removed according to the pipe diameter (2). Locking pins are threadless and can easily be removed to remove or add clamps (1), adjusting tool to pipe diameter.
Para ajustar a posição das presilhas (1) na tubulação (2) durante o acoplamento, são utilizados grampos (3) que possuem um parafuso de ajuste (4) e um parafuso de estabilização (5), com ponta anti-rotacional que não marcam nem danificam a tubulação. O parafuso de ajuste (4) tem a função de fixar a presilha (1) e o grampo (3) na tubulação (2), para realizar o acoplamento. Já o parafuso de estabilização (5) tem a função de controlar a inclinação do grampo (3) garantindo que ele fique paralelo à tubulação (2), gerando uma maior estabilidade durante a montagem. O grampo (3) apresenta duas garras inferiores (6) que permitem a sua montagem e desmontagem a qualquer momento e em qualquer presilha. O grampo (3) possui ainda um parafuso de segurança (7) que tem a função de evitar que o grampo (3) desencaixe da presilha (1) em algum momento não desejado pelo operador.  To adjust the position of the clamps (1) in the piping (2) during coupling, clamps (3) are used which have an adjusting screw (4) and a stabilizing screw (5) with non-rotating tip nor damage the tubing. The adjusting screw (4) has the function of fixing the clamp (1) and the clamp (3) to the piping (2), to perform the coupling. The stabilizing screw (5) has the function of controlling the inclination of the clamp (3) ensuring that it is parallel to the pipe (2), generating greater stability during assembly. The clamp (3) has two lower claws (6) that allow its mounting and dismounting at any time and in any clip. The clamp (3) further has a safety screw (7) which has the function of preventing the clamp (3) from detaching from the clamp (1) at any time undesired by the operator.
Para apertar o conjunto de presilhas é utilizado um dispositivo chamado compasso, que utiliza um sistema articulável (8) e um fuso (9) para proporcionar o aperto da cinta flexível, oferecendo a vantagem de ser compacto, leve, resistente e permitir o ajuste para vários diâmetros da tubulação. To tighten the set of clips is used a device called compass, which uses a pivoting system (8) and a spindle (9) to Provide flexible strap tightening, offering the advantage of being compact, lightweight, sturdy and allow adjustment for various pipe diameters.
Esta nova tecnologia permite realizar a montagem do tipo tubo-tubo apenas com a cinta flexível e com o compasso, não necessitando dos grampos. Isto facilita a montagem e reduz em cerca de 50% o tempo necessário para realizar o acoplamento, o que gera aumento de produtividade e consequentemente ganhos económicos. Permite realizar também montagens do tipo tubo-curva, tubo-conexão T, tubo-flange e ainda tubo-redução, o que não é possível com outras acopladeiras existentes, sem restrições.  This new technology makes it possible to assemble the tube-tube type only with the flexible strap and the compass, without the need for clamps. This facilitates assembly and reduces the time required for coupling by about 50%, resulting in increased productivity and consequently economic gains. It also allows the assembly of tube-bend, tube-T-connection, tube-flange and tube-reduction assemblies, which is not possible with other existing couplers without restrictions.
As tubulações industriais geralmente são fornecidas com desvios de ovalização que dificultam a montagem e acoplamento. Esta nova ferramenta possui também a capacidade de corrigi!" estes desvios de ovalização. Esta correção é feita por meio do parafuso de ajuste (4) e do parafuso de estabilização (5). Utilizando um instrumento de medição (Hi-lo) que compara o valor do diâmetro da tubulação em vários pontos, é possível apertar o parafuso de ajuste (4) e o parafuso de estabilização (5) para reduzir a ovalização na tubulação (2) onde será realizado o acoplamento.  Industrial piping is usually supplied with ovality deviations that make assembly and coupling difficult. This new tool also has the ability to correct these ovality deviations. This correction is made by means of the adjusting screw (4) and the stabilizing screw (5). Using a measuring instrument (Hi-lo) that compares With the pipe diameter value at various points, the adjusting screw (4) and stabilizing screw (5) can be tightened to reduce ovality in the pipe (2) where the coupling will be performed.
E principalmente, esta nova tecnologia permite uma versatilidade na sua utilização por ser altamente resistente e possuir vida longa, dispor de operações de manuseio simples e rápidas, até mesmo para quem tem pouca experiência, e possuir ajustes firmes e precisos. As suas soluções são apresentadas de maneira inovadora aos problemas existentes no estado da técnica e até então não solucionados.  And most importantly, this new technology enables versatility in its use as it is highly durable and long-lived, has simple and fast handling operations, even for those with little experience, and has firm and precise adjustments. Their solutions are presented in an innovative way to problems that exist in the prior art and hitherto unresolved.
A Acopladeira Flexível, objeto da presente invenção, foi desenvolvida para atender a uma ampla faixa de diâmetros de tubos com um único modelo. Basta apenas acrescentar ou remover as presilhas, ajustando a ferramenta a qualquer diâmetro de tubulação industrial.  The Flexible Coupler, object of the present invention, was developed to meet a wide range of pipe diameters with a single model. Simply add or remove the clamps, adjusting the tool to any industrial pipe diameter.
Portanto, a Acopladeira Flexível, aqui descrita, apresenta importante inovação e vantagens sobre o estado da técnica contribuindo para o desenvolvimento dessa área tecnológica pelas soluções apresentadas aos problemas existentes. Para realizar a montagem da cinta flexível durante seu uso foi desenvolvido um método de acoplamento para evitar erros do operador e facilitar a montagem. Como descrito anteriormente, as presilhas (1) que compõem a cinta flexível podem ser conectadas entre si por parafusos ou pinos-trava. Os pinos-trava não possuem rosca, podendo ser facilmente removidos, enquanto que os parafusos precisam ser desenroscados. O método de acoplamento consiste em usar pinos- trava apenas nas presilhas que correspondem à troca de diâmetros padronizados. Estes pinos-trava são marcados com o valor do diâmetro ao qual ele corresponde, permitindo que o operador retire apenas o pino que interessa de acordo com a tubulação em que ele esta montando a cinta flexível. Therefore, the Flexible Coupler described here presents important innovation and advantages over the state of the art, contributing to the development of this technological area by the solutions presented to the existing problems. To perform the flexible belt assembly during use, a coupling method has been developed to avoid operator errors and ease of assembly. As previously described, the clips (1) that make up the flexible strap can be connected to each other by screws or locking pins. The locking pins are threadless and can be easily removed while the screws need to be unscrewed. The coupling method consists of using locking pins only on the clamps that correspond to the exchange of standard diameters. These locking pins are marked with the diameter value to which they correspond, allowing the operator to remove only the pin of interest according to the tubing on which he is mounting the flexible strap.
