Abstract
The system comprises pivoted bars (8,10) respectively attached to a ditch (3) by the shaft (9) and to the trap by another shaft (11) that further lodges the unlocking drive (12). The trap (5) is locked, thus closing the ditch (3), by means of a hydraulic/electromechanical activator (6) that drives a locking pin (13). When the container is replaced in the ditch (3), this action and the weight of the container actuate the unlocking drive (12), disabling the system and thus allowing the trap (5) to open.

SISTEMA DE BLOQUEIO DE ALÇAPÃO Trap Lock System
Domínio técnico da invenção Technical field of the invention
[1 ] A presente invenção tem aplicação em sistemas de contentorização de resíduos, cujo contentor está enterrado num fosso que se pode tornar acessível e perigoso para qualquer pedestre situado perto do equipamento. [1] The present invention has application in waste containerization systems, the container of which is buried in a pit that can be made accessible and dangerous to any pedestrian near the equipment.
Sumário summary
[2] O sistema enterrado de resíduos sólidos é composto tradicionalmente por um [2] The buried solid waste system is traditionally composed of a
contentor (1), um fosso (3), uma tampa (2) para o fosso e por um marco de deposição (4). Aquando da recolha, o contentor é retirado do fosso(3), criando-se uma potencial fonte de perigo a pessoas e animais que circulem na sua proximidade. Para eliminar esse problema tornar-se-ia necessário a introdução de uma plataforma móvel de modo a fechar o fosso. O sistema proposto assenta no uso de uma plataforma constituída por alçapão (5) que roda sobre uma extremidade encostada próximo da parede do fosso, retraindo-se a plataforma para possibilitar a passagem e acomodação do contentor no fosso. O alçapão necessita ter um movimento de rotação aquando da extracção/ introdução do contentor. O movimento para cima é conseguido com um actuador de fluido/electromecânico (6), em que um cilindro pressurizado com gás exerce uma força capaz de elevar o alçapão, más que ao mesmo tempo possibilita que a sua força seja vencida pelo peso do contentor aquando do movimento descendente do contentor para o interior do fosso. Para garantir que o alçapão se mantenha fechado (posição superior) é necessário incluir um sistema de bloqueio , esse sistema de bloqueio terá de ser desactivado automaticamente quando o contentor toca na superfície do alçapão, sendo que esse desbloqueio tem de ser memorizado até que o alçapão volte à posição de fechado . container (1), a pit (3), a lid (2) for the pit and a deposition mark (4). Upon collection, the container is removed from the pit (3), creating a potential source of danger to people and animals in the vicinity. To eliminate this problem, it would be necessary to introduce a mobile platform to close the gap. The proposed system is based on the use of a trapdoor platform (5) that rotates on an end near the ditch wall, retracting the platform to allow the container to pass and accommodate in the ditch. The trapdoor needs to have a rotating movement when extracting / introducing the container. Upward movement is achieved with a fluid / electromechanical actuator (6), wherein a pressurized gas cylinder exerts a force capable of raising the trapdoor, but at the same time enables its force to be overcome by the weight of the container when downward movement of the container into the pit. To ensure that the trap door remains closed (top position) a locking system must be included, that locking system must be deactivated automatically when the container touches the surface of the trapdoor, and this unlocking must be memorized until the trapdoor return to the closed position.

[4] Relativamente à Patente ES 1053G24U este sistema propõe uma forma para garantir a segurança por meio do accionamento de correntes que se elevam e esticam quandoa plataforma roda sobre o seu eixo, contudo não existe protecção frontal pois não existem correntes nessa posição. [4] With respect to ES 1053G24U this system proposes a way to ensure safety by driving up and extending chains when the platform rotates about its axis, however there is no frontal protection as there are no chains in that position.
[5 ] Na patente DE 202004017744U1 é apresentada uma plataforma elevatória que se eleva aquando da remoção de um contentor do fosso, contudo, a forma de actuação ou
retenção das posições assinaladas não é mencionada, não dando resposta a estes problemas específicos. [5] DE 202004017744U1 discloses a lifting platform that rises upon removal of a pit container, however, the form of action or retention of marked positions is not mentioned and does not address these specific problems.
[6] Na Patente PT 103574B é mencionado um alçapão rotativo sobre um eixo com um sistema de bloqueio diferente do apresentado nesta invenção. [6] In PT 103574B there is mentioned a rotary trapdoor with a locking system different from that disclosed in this invention.
[7] A presente invenção permite a resolução do problema do bloqueio do sistema na sua posição superior (aberta)e sistema de 'memória' quando o sistema é actuado, não bloqueando até que a plataforma esteja novamente na horizontal(posição fechada). Este novo sistema permite também um equilíbrio constante do contentor no movimento da introdução no fosso, pois apenas um alçapão torce o contentor no momento do accionamento encravando o contentor entre o fosso e a plataforma. [7] The present invention allows solving the problem of locking the system in its upper (open) position and 'memory' system when the system is operated, not locking until the platform is again horizontal (closed position). This new system also allows a constant balance of the container in the movement of introduction into the pit, as only a trapdoor twists the container at the moment of actuation, jamming the container between the pit and the platform.
