Large-sized adjustable container counterweight device

The invention relates to a large-sized adjustable container counterweight device comprising a base. A primary double-layer guide box with a sandwich structure and a plurality of secondary single-layer guide plates are arranged on the base, the secondary single-layer guide plates are at least partially accommodated in the sandwich structure in an adaptive way, the plurality of secondary single-layer guide plates are connected end to end so as to form an adjustable box body structure, and the base is also provided with double-stage oil cylinders matched with the primary double-layer guide box and the secondary single-layer guide plates. A container counterweight is employed to replace a traditional small counterweight block; a container counterweight filler can be sandy soil, can be obtained on site, and the manufacturing cost can be greatly reduced through replacing a traditional cast iron counterweight with the container counterweight; when the container counterweight is not in use, the sandy soil is removed, only a container needs to be transported, and thus the transportation is convenient and the cost is reduced; and a certain pressure can be also applied by a hydraulic structure so as to compact the sandy soil, so that uniformity of the sandy soil in the container counterweight is ensured.
