Description

SISTEMA DE APOIO E CALÇAMENTO DE VEÍCULO DE CARGA ACOPLÁVEL A VEÍCULO MOVIMENTADOR SUPPORT SYSTEM AND CHARGING OF LOAD VEHICLE COUPLABLE TO MOVING VEHICLE
[001] A presente invenção descreve um sistema de apoio e calçamento de veículo de carga acoplado em veículos do tipo cavalo mecânico utilizado em transporte de cargas agrícolas em pátios de carga e descarga localizados em terrenos acidentados. [001] The present invention describes a support and pavement system for cargo vehicles coupled to vehicles of the mechanical horse type used in transporting agricultural loads in loading and unloading yards located in rough terrain.
ESTADO DA TÉCNICA TECHNICAL STATUS
[002] Em lavouras de produtos agrícolas como cana de açúcar, cuja colheita é feita em alta escala e em grandes velocidades, é necessário que as colheitadeiras rapidamente colham o produto em questão e o levem o mais rápido possível para que seja descarregado em caminhões de transporte de cana, a fim de que seja liberado espaço nas colheitadeiras para continuar a colheita da cana de açúcar. [002] In crops of agricultural products such as sugar cane, whose harvest is done on a large scale and at high speeds, it is necessary that the harvesters quickly harvest the product in question and take it as quickly as possible to be unloaded in trucks. sugar cane transport, in order to free up space in the harvesters to continue harvesting the sugar cane.
[003] Os caminhões de carga de cana de açúcar costumam ser dotados de um cavalo mecânico e uma carreta, a qual é carregada com a cana de açúcar recentemente colhida. A carreta pode ser única, ou ainda conter mais uma ou duas outras carretas acopladas a ela. Essa carreta deve ser engatada ao cavalo mecânico para que seja adequadamente puxada até uma área de descarga, que normalmente é uma usina de beneficiamento de cana de açúcar para produção de álcool, etanol, açúcar propriamente dito e outros derivados. [003] Sugar cane cargo trucks are usually equipped with a mechanical horse and a cart, which is loaded with the recently harvested sugar cane. The trailer may be single, or contain one or two other trailers attached to it. This cart must be coupled to the mechanical horse so that it is properly pulled to an unloading area, which is usually a sugar cane processing plant for the production of alcohol, ethanol, sugar itself and other derivatives.
[004] As carretas, enquanto estão sendo abastecidas com a cana recém colhida pelas colheitadeiras costumam ficar estacionadas e posicionadas em um pátio reservado a elas em uma área da própria lavoura, um terreno não pavimentado, normalmente acidentado, barrento e cheio de terra, a fim de facilitar o trabalho das colheitadeiras. [004] The carts, while being supplied with the sugarcane freshly harvested by the harvesters, tend to be parked and positioned in a courtyard reserved for them in an area of the plantation itself, an unpaved land, usually rough, muddy and full of soil, to facilitate the work of harvesters.
[005] E comum que o número de carretas para o transporte da cana de açúcar colhida seja muito maior do que a quantidade de cavalos mecânicos disponíveis para puxar as respectivas carretas. Dessa forma, enquanto uma carreta está posicionada no pátio para ser carregada com o resultado da produção agrícola, outra é conduzida para a usina de beneficiamento, num processo que tem que ser rápido, contínuo e ininterrupto pelas 24 horas diárias, aonde qualquer desperdício de tempo pode gerar um grande impacto na colheita da cana. [005] It is common for the number of carts to transport the harvested sugar cane to be much greater than the number of mechanical horses available to pull the respective carts. That way, while a a trailer is positioned in the yard to be loaded with the result of agricultural production, another is driven to the processing plant, in a process that has to be fast, continuous and uninterrupted for 24 hours a day, where any waste of time can generate a great impact in the sugarcane harvest.
[006] Uma característica construtiva que essas carretas costumam apresentar é um grande comprimento. O conjunto de rodas dessas carretas normalmente ficam posicionadas mais próximas da sua extremidade final, ou seja, atrás da linha mediatriz da carreta. Isso se dá pelo fato de a carreta ficar perfeitamente equilibrada quando devidamente acoplada ao cavalo mecânico. No entanto, quando a careta não estiver acoplada ao cavalo mecânico, é necessário um sistema de pés ou calços (popularmente conhecido como patolas) para apoiar e manter em balanço a carreta. [006] A constructive characteristic that these carts usually present is a great length. The set of wheels of these carts are usually positioned closer to their final end, that is, behind the mediator line of the car. This is due to the fact that the cart is perfectly balanced when properly attached to the mechanical horse. However, when the face is not attached to the mechanical horse, a system of feet or wedges (popularly known as foot pads) is needed to support and keep the cart in balance.
[007] Esse sistema de patolas costuma ser acionado mecanicamente, quase de forma manual, sendo necessários três operadores para executarem a operação de subida e descida dos pés, bem como para checar e conduzir o perfeito acoplamento do conjunto cavalo mecânico e carreta. [007] This pad system is usually mechanically operated, almost manually, requiring three operators to perform the operation of raising and lowering the feet, as well as to check and conduct the perfect coupling of the mechanical horse and cart set.
[008] Por envolver três trabalhadores simultaneamente, essa é uma etapa extremamente crítica para o carregamento e transporte das carretas, pois costumam acontecer muitos acidentes, como o tombamento da carreta por uma patola mal calçada junto ao piso, bem como o impacto, atropelamento e ainda esmagamento de membros de trabalhadores na acoplagem da carreta, uma vez que os trabalhadores estão na região aonde se localizam as patolas, o seu respectivo sistema de subida e descida e o ponto de acoplagem da carreta com o cavalo mecânico. Pela forma como ela é executada, essa etapa requer muito cuidado, o que faz com que o tempo para sua execução seja em tomo de 10 minutos. [008] As it involves three workers simultaneously, this is an extremely critical step for loading and transporting the carts, as many accidents usually happen, such as tipping the car by a badly paved sidewalk close to the floor, as well as impact, being run over and crushing of workers' limbs when coupling the cart, since the workers are in the region where the potholes are located, their respective up and down system and the coupling point of the cart with the mechanical horse. Due to the way it is performed, this step requires a lot of care, which means that the time for its execution is around 10 minutes.
[009] Dessa forma, visando aumentar a segurança da operação de descida e subida das patolas e agilizar toda essa etapa, a presente invenção a seguir descrita revela um sistema automatizado de apoio e calçamento de veículo de carga. [009] Thus, in order to increase the safety of the lowering and raising of the flaps and to speed up this whole stage, the present invention The following describes an automated load vehicle support and paving system.
