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

A kind of large-scale adjustable freight container weight-balancing device

Technical field

The present invention relates to a kind of bullfrog, particularly relate to a kind of large-scale adjustable freight container weight-balancing device.

Background technology

Counterweight block is the counterweight of crawler crane lifting, and along with the crawler crane tonnage is increasing, the weight of counterweight block is increasing, kiloton on much hundreds of tons.

Traditional counterbalanced weight is the cast iron counterbalanced weight, and as shown in Figure 1, for convenient transportation, the weight of existing counterbalanced weight is traditionally arranged to be 10 tons.Exploitation along with hoister in large tonnage, need the quantity of counterweight block to become more and more huger, be 2000 tons of hoisting cranes such as certain tonnage, the demand counterbalanced weight is more than 1300 ton, counterweight block according to usually design is 10 tons/piece, then need at least 130 polylith counterbalanceds weight, this brings very large inconvenience to transportation, and traffic cost is too high.

On the other hand, counterbalanced weight mainly is divided into three kinds according to its layout: the counterbalanced weight of getting on the bus, the counterbalanced weight of getting off reach and have surpassed counterbalanced weight.Get on the bus counterbalanced weight and the counterbalanced weight of getting off is subjected to the restriction of size, is typically designed to the cast iron counterweight block that density is large, size is little; But surpassed often not restriction of counterbalanced weight, and being in great demand of counterweight block, therefore, it is feasible reducing this part cost that has surpassed counterweight block and transportation volume, and has larger realistic meaning.
