Abstract

Inventia se refera la o instalatie pentru confecsionarea de prefabricate din beton, spre exemplu boltari necesari sustinerilor lucrarilor miniere subterane. Instalatia include niste placi tampon fixate la o platforma mobila care poate fi deplasata, sub actiunea unui cilindru hidraulic în lungul unor grinzi longitudinale apartinand unui cadru fix. Tot la platforma mobila este montat un suport care poate fi ridicat odata cu cofrajul cu ajutorul unui cablu de otel actionat în miscare prin intermediul unui cilindru hidraulic. Cablul de otel este dirijat prin niste role scripeti montate pe platforma mobila, iar cofrajul prin deplasarea platformei mobile este adus pe o alta platforma unde placile tampon depun prefabricatele la ridicarea cofrajului. Prin actionarea cilindrilor hidraulici în sens invers cofrajul este apoi adus în pozitia de montare pe masa vibranta.The invention relates to a plant for the manufacture of prefabricated concrete, for example blocks necessary for the support of underground mining works. The installation includes a buffer plate fixed to a mobile platform that can be moved under the action of a hydraulic cylinder along longitudinal beams belonging to a fixed frame. A support that can be lifted with the formwork by means of a steel cable driven in motion by a hydraulic cylinder is also mounted on the mobile platform. The steel cable is routed through roller bearings mounted on the mobile platform, and the formwork by moving the mobile platform is brought to another platform where buffers deposit the prefabricates when the formwork is lifted. By actuating the hydraulic cylinders in reverse direction, the formwork is then brought into the mounting position on the vibrating table.
