The safe supporting device is particularly applied to a safe supporting device which is used for supporting the weight and is convenient to move and is used for placing the weight on the plane of an upper box sand box before casting and pouring.
Background
In the casting field, the ductile cast iron generates buoyancy in the pouring process and generates secondary graphite expansion force in the cooling process, and the steel structure of the conventional sand box cannot overcome the influence of the buoyancy and the secondary graphite expansion force on the lifting of the rib plate on the upper part of the sand box. The lifting of the rib plate on the upper part of the sand box can cause the size of the casting and the internal shrinkage and loosening defects. In order to avoid the sand box from lifting due to buoyancy and secondary graphite expansion force and influence on casting quality, a weight iron with certain coefficient weight is pressed before pouring. To prevent the weight from pressing to the riser; the weight of the weight iron is also ensured to be evenly distributed on the sand box; and simultaneously, the air exhaust of the cavity after pouring is prevented from being blocked by directly pressing the weight on the sand box. A weight support frame may be generally used to support the weight.
The volume and the quality of wind power product castings are generally large, the conventional weights are not easy to meet the requirements, generally, the weights are placed by combining 4 support frames provided with the weights, the supports are respectively hoisted by a crane to be stacked on a sand box, the lower part of the support frame is provided with two blocks, and the upper part of the support frame is provided with two blocks.
