Description

Loading and unloading device for hot die ductile cast iron pipe plug Technical Field The utility model belongs to the technical field of mechanical tools, and particularly relates to a loading and unloading device for a hot die ductile iron pipe plug. Background In the lining process, a bell and spigot plug is required to be accurately nested on a spigot of the ductile cast iron pipe and firmly fixed, so that cement mortar is blocked, and the ductile cast iron pipe is prevented from being thrown out during high-speed centrifugal operation, thereby ensuring the lining quality. However, the socket plug tool for the large-caliber ductile cast iron pipe is large in size and heavy in weight, at present, an electric hoist and a single-beam crane are commonly adopted in the industry to assist in manually completing the installation work of the socket plug, and the traditional operation mode has a plurality of defects: On the one hand, the efficiency is extremely low, a great deal of time and energy are consumed for manual operation, each plug is installed by workers for fine positioning, adjustment and fixation, the whole process is tedious and slow, the production efficiency is severely restricted, and the requirement of mass production is difficult to meet; On the other hand, the safety risk is higher, because the plug is large in size and heavy in weight, accidents such as injury to workers and equipment damage can occur due to slight carelessness in the lifting and manual installation processes, and serious threat is formed to the life safety of the workers and the property safety of enterprises; In addition, be difficult to guarantee in the manual installation that the bell and spigot end cap can closely laminate with the bell and spigot edge, because there is subjectivity and uncertainty in manual operation, it is difficult to accomplish accurate location and firm fixed, this just leads to in the high-speed centrifugation in nodular cast iron pipe, cement mortar appears leaking the material phenomenon easily, cement mortar's leaking the material can not only influence the life cycle of frock, increase the manufacturing cost of enterprise, still can cause serious influence to nodular cast iron pipe bell and spigot inside lining quality, lead to the damage of bell and spigot edge inside lining, thickness inhomogeneous scheduling defect, reduce nodular cast iron pipe's overall quality.
