Double-insurance safety sand core storage and transportation vehicle

Abstract

A double-insurance safe sand core storage and transportation vehicle belongs to the technical field of placing trolleys and comprises a bottom plate with moving wheels at the bottom, a side wing plate is fixedly mounted on the left side of the upper surface of the bottom plate, a plurality of laminates with supporting foot plates are rotatably mounted on the right surface of the side wing plate, and hinge pieces are integrally formed on the front surface and the rear surface of the side wing plate. Air pressure supporting rods are rotationally installed between the hinge pieces and the layer plates, a plurality of protection hooks and a plurality of supporting screws are installed on the front surface and the rear surface of the side wing plate, inclined face parts A, arc-shaped parts B and lower grooves C are arranged at the right ends of the protection hooks, the protection hooks are horizontally erected on the corresponding supporting screws, and hanging shafts are fixedly installed on the front surface and the rear surface of each layer plate. According to the utility model, the situation that the laminate cannot maintain the fixed position after upturning due to the failure of the air pressure supporting rod can be effectively avoided. And meanwhile, the fixing of the upturned shelf board does not need additional complex operation, the shelf board can be fixed only by normally upturning the shelf board, and the operation is simple, convenient and efficient.
