Description
Technical Field
The utility model relates to a repository, specifically heavy load automatic storage storehouse.
Background
The stampings on the automobile body are largely divided into covering pieces, beam pieces and general stampings. The stamping capable of obviously representing the characteristics of the automobile image is an automobile covering part. Therefore, the more specific automobile mold can be called as an automobile panel stamping mold. The stamping die for the automobile covering parts is shortened. For example, a front door outer panel trimming die, a front door inner panel punching die, and the like are used, and of course, not only the body of an automobile has a stamped part. The dies of all stamping parts on the automobile are called as 'automobile stamping dies', the existing storage warehouse for heavy parts (such as automobile stamping dies, steel coils and the like) is generally in a field stacking type for storing materials, has the disadvantages of messy stacking, low space utilization rate and difficult carrying, adopts a man-operated vehicle, generally has a hoisting weight of 50 tons, and has high bearing requirement and high manufacturing cost of factory foundations.
The existing automobile stamping die stacking site or other heavy part stacking sites require that the ground bearing capacity is much higher than that of the ground bearing capacity of a common factory during construction, the cost is high, and the common site is about 3 billion yuan.
