Assunto: Subject:
[001] A presente Patente de Invenção refere-se a um para-choque extensível aplicado em chassi utilizado para o transporte de contêineres de 40 pés, com o principal objetivo de proporcionar que estes possam transportar contêineres de 40, 45 ou 53 pés, a partir da regulagem do para- choque, que pode ser estendido para além da configuração inicial do chassi, fazendo parte deste. Como diferencial apresenta ainda travamento duplo por sistema pneumático independente, contando com posições pré- definidas em função da utilização de contêineres de 40, 45 e 53 pés, roletes próprios para deslizamento e dispositivos de fixação do contêiner, chamados na prática de DIF, dispostos na parte móvel do chassi, além de conter outras vantagens. [001] This patent refers to an extendable bumper applied to a chassis used to transport 40-foot containers, with the main objective of providing that they can transport 40-, 45- or 53-foot containers, at starting from the adjustment of the bumper, which can be extended beyond the initial configuration of the chassis, forming part of it. As a differential, it also features double locking by an independent pneumatic system, with pre-defined positions depending on the use of 40, 45 and 53 feet containers, rollers for sliding and container fastening devices, called in practice DIF, arranged in the moving part of the chassis, in addition to containing other advantages.
Estado da Técnica: State of the Technique:
[002] Semirreboques utilizados para transporte de contêineres são conhecidos e utilizados há muito pela técnica, sendo aptos a transportar contêineres de 20, 40, 45 e 53 pés. Em geral constituem-se de semirreboques formados por chassi próprio que contempla longarinas e travessas de modo a proporcionar que engates próprios para contêineres, os DIFs, estejam posicionados nos locais devidos para que possam fixar os containers e transportá-los em segurança. Em geral tem-se veículos próprios para transporte de contêineres de 20 e 40 pés, sendo necessários veículos com outras disposições de chassi para o transporte de contêineres de 45 e 53 pés, sendo necessário, portanto, pela técnica atual, a utilização de semirreboques diferentes em função das diferentes dimensões dos contêineres. Este fator encarece, dificulta e inviabiliza, em muitos casos, o transporte principalmente dos contêineres maiores, de 45 e 53 pés, os quais vem sendo cada vez mais utilizados. [003] Com relação à semirreboques utilizados para transporte de contêineres, não é conhecida solução cujo chassi possa ser estendido em seu para-choque de modo a possibilitar transportes de múltiplos containers. Os possíveis implementos que poderiam realizar o transporte dos contêineres maiores, possuem dimensões fixas e imutáveis, não alteram seu comprimento para absorver os diferentes contêineres propostos. [002] Semi-trailers used to transport containers are known and used for a long time by the technique, being able to transport containers of 20, 40, 45 and 53 feet. In general, they consist of semi-trailers formed by their own chassis that includes stringers and sleepers in order to provide that proper couplings for containers, the DIFs, are positioned in the appropriate places so that they can fix the containers and transport them safely. In general, there are vehicles suitable for transporting 20 and 40-foot containers, requiring vehicles with other chassis arrangements to transport 45- and 53-foot containers. depending on the different dimensions of the containers. This factor makes transport more expensive, difficult and in many cases unfeasible, mainly the larger containers, 45 and 53 feet, which are being used more and more. [003] With regard to semi-trailers used to transport containers, there is no known solution whose chassis can be extended on its bumper in order to allow transport of multiple containers. The possible implements that could carry out the transport of larger containers, have fixed and immutable dimensions, do not change their length to absorb the different proposed containers.
[004] Especificamente com relação ao para-choque extensível, em seu sentido longitudinal, referentes às referências patentárias existem documentos que mostram para-choques com regulagem como sendo um acessório ao veículo, e não fazem parte da sua estrutura. Dentre estes podemos citar o documento CN 2013074418-1 publicado em 19/03/2014, que se refere a um para-choque extensível a partir de um movimento de rotação. [004] Specifically with regard to the extendable bumper, in its longitudinal direction, referring to patent references, there are documents that show adjustable bumpers as an accessory to the vehicle, and are not part of its structure. Among these we can mention the document CN 2013074418-1 published on 03/19/2014, which refers to an extensible bumper from a rotation movement.
[005] O documento BR 202015 032707-8 depositado em 28/12/2015 por AGILIFT descreve um para-choque constituído por travessas dotadas de elementos telescópicos movidos por pistão hidráulico ou pneumático, fixados por pinos quando colocados na posição desejada. O documento CN 209921239 publicado em 10/01/2020 antecipa um para-choque cuja regulagem se dá por operação manual, com regulagem de posicionamento vertical. [005] Document BR 202015 032707-8 filed on 12/28/2015 by AGILIFT describes a bumper consisting of crossbeams equipped with telescopic elements driven by a hydraulic or pneumatic piston, fixed by pins when placed in the desired position.

Descrição: Description:
[013] O Para-choque Extensível Aplicado em Chassi Para Transporte de Contêiner compreende o chassi (1 ) que contempla em sua parte traseira o para-choque extensível (2) formado pelas longarinas (3) que deslizam no interior ou junto às longarinas (4) do chassi (1 ), sendo que as longarinas (3) possuem função estrutural de absorção de carga. [014] Para que o deslizamento se dê de forma suave das longarinas (3), junto às longarinas (4) do chassi (1 ) os roletes (5) são fixados aos suportes (6), dispostos bilateralmente. De forma opcional, as longarinas (3) podem conter placas autolubrificantes (7) que cumprem o objetivo de diminuir o atrito entre estas e as longarinas (4) do chassi (1 ), prolongando a vida útil do conjunto. [013] The Extensible Bumper Applied to Chassis for Container Transport comprises the chassis (1) which includes in its rear part the extensible bumper (2) formed by the stringers (3) that slide inside or next to the stringers ( 4) of the chassis (1), and the stringers (3) have a load-absorbing structural function. [014] In order for the stringers (3) to slide smoothly, together with the frame stringers (4) (1), the rollers (5) are attached to the supports (6), arranged bilaterally. Optionally, the side members (3) can contain self-lubricating plates (7) that fulfill the purpose of reducing the friction between them and the side members (4) of the chassis (1), prolonging the useful life of the set.
[015] Na extremidade do para-choque extensível (2) a travessa (8) contempla, bilateralmente, os dispositivos de fixação do contêiner (9), chamados comumente de DIFs, os quais também podem ser dispostos na extremidade das longarinas (4) do chassi (1 ), em posição fixa. Com a extensão pela movimentação deslizante das longarinas (3), os dispositivos de fixação do contêiner (9) são posicionados para que possam fixar contêineres de 45 e 53 pés, conforme mostram as figuras 2 e 3. [015] At the end of the extensible bumper (2) the crosspiece (8) includes, bilaterally, the container fastening devices (9), commonly called DIFs, which can also be arranged at the end of the stringers (4) of the chassis (1 ), in a fixed position. With the extension by the sliding movement of the stringers (3), the container fixing devices (9) are positioned so that they can fix 45 and 53 foot containers, as shown in figures 2 and 3.
[016] Na extremidade do para-choque extensível (2) também é fixada a carenagem para lanternas e iluminação traseira (10), para-choque (11 ) e placa de veículo longo (12), além de suporta para identificação (placa) do veículo. [016] At the end of the extendable bumper (2) the fairing for taillights and rear lighting (10), bumper (11) and long license plate (12) is also attached, in addition to an identification support (plate) of the vehicle.
[017] O acionamento do para-choque extensível (2) para movimentação das longarinas (3) se dá pelo sistema pneumático de freio do implemento junto ao sistema pneumático de acionamento do para-choque extensível (2), os quais são divididos por intermédio de uma válvula reguladora de fluxo (13), que garante a condição mínima de funcionamento dos freios caso o sistema pneumático do para-choque extensível seja afetado por qualquer eventualidade. Neste caso, a interação dos dois sistemas se resume à alimentação de ar comprimido de um sistema para o outro com a proteção de uma válvula reguladora de fluxo, possibilitando que o cilindro hidráulico (14) seja movimentado para a extensão e recolhimento do para- choque extensível (2). [017] The activation of the extensible bumper (2) for moving the stringers (3) is given by the pneumatic brake system of the implement together with the pneumatic system for activating the extensible bumper (2), which are divided through of a flow regulating valve (13), which guarantees the minimum operating condition of the brakes in case the pneumatic system of the extendable bumper is affected by any eventuality. In this case, the interaction of the two systems boils down to supplying compressed air from one system to the other with the protection of a flow regulator valve, allowing the hydraulic cylinder (14) to be moved to extend and retract the bumper. extendable (2).
[018] O travamento do posicionamento do para-choque extensível (2) se dá pelo acionamento da válvula de acionamento pneumático (15) em conjunto aos cilindros de atuação (16), sendo um travamento redundante, ou seja, no caso de falha de um dos cilindros de atuação (16), o outro assume o funcionamento imediatamente. [018] The locking of the positioning of the extendable bumper (2) occurs by activating the pneumatically operated valve (15) in set to the actuation cylinders (16), being a redundant locking, that is, in case of failure of one of the actuation cylinders (16), the other takes over the operation immediately.
[019] Além disso, em caso de vazamento ou falta de ar pressurizado ambos os cilindros de atuação (16) retornam à posição de segurança, para acoplar no próximo alojamento de travamento disponível, conforme deslocamento do para-choque extensível. [019] In addition, in case of leakage or lack of pressurized air, both actuation cylinders (16) return to the safety position, to couple in the next available locking housing, according to the displacement of the extensible bumper.
[020] Também de forma redundante, mas não menos importante, os contrapinos (17) servem como limitador de curso para a abertura total do para-choque extensível (2), evitando situações em que o para-choque possa de alguma forma de desprender do chassi. [020] Also redundantly, but not least, the cotter pins (17) serve as a travel limiter for the total opening of the extensible bumper (2), avoiding situations where the bumper can somehow detach from the chassis.
[021] O sistema pneumático pode, opcionalmente, ser substituído por sistema elétrico, hidráulico, hidropneumático, mecânico ou outro similar. [021] The pneumatic system can optionally be replaced by an electrical, hydraulic, hydropneumatic, mechanical or similar system.
[022] Da mesma forma o cilindro hidráulico (14) pode ser, opcionalmente, substituído por similares conhecidos como atuadores de funcionamento manual, pneumático, cremalheira, rosca ou outros. [022] Likewise, the hydraulic cylinder (14) can be optionally replaced by similar actuators known as manual, pneumatic, rack, screw or other actuators.
Conclusão: Conclusion:
[023] Deste modo, o Para-choque Extensível Aplicado em Chassi Para Transporte de Contêiner é subsidiado por características funcionais inéditas, merecendo, portanto, a proteção legal pleiteada. [023] In this way, the Extensible Bumper Applied on Chassis for Container Transport is subsidized by unprecedented functional characteristics, therefore deserving the claimed legal protection.
