Large-sized adjustable container counterweight device

Abstract

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.

Description

technical field [0001] The invention relates to a balance weight device, in particular to a large-scale adjustable container balance weight device. Background technique [0002] The balance weight is the lifting weight of the crawler crane. As the tonnage of the crawler crane increases, the weight of the balance weight becomes larger and larger, ranging from hundreds to thousands of tons. [0003] The traditional balance weight is cast iron balance weight, such as figure 1 As shown, in order to facilitate transportation, the weight of the existing balance weight is generally set at 10 tons. With the development of large-tonnage cranes, the number of counterweights required becomes larger and larger. For example, for a crane with a tonnage of 2,000 tons, the required balance weight is more than 1,300 tons. According to the usual design of the balance weight is 10 tons per block, Then at least more than 130 counterweights are needed, which brings great inconvenience to trans...
