Combined counterweight for excavator detachable recovery

Abstract

The invention provides a combined counterweight for detachable recovery of an excavator. The combined counterweight comprises a bottom plate, a filling module and a shell, wherein a web plate is arranged below the bottom plate; a supporting plate is arranged on the bottom plate on the upper side of the web plate; guide columns are arranged between the supporting plate and the web plate; the filling module is fixedly pressed between the guide columns on the bottom plate through a pressing plate; the shell is arranged on the outer side of the filling module; the shell and the bottom plate are arranged on the bottom plate through positioning cylindrical pins and bolts; the bottom plate and the shell are provided with lifting holes; the filling module comprises a first filling block, a second filling block and a third filling block. Through modularized design of the filling module, the defects that the conventional filling counterweight is arranged in a non-detachable manner and cannot be recycled and reutilized without damage are overcome, and the defect of higher cost of a cast iron type counterweight is overcome. The combined counterweight has the characteristics of convenience in assembly and disassembly, compact structure and reusability of the filling module, and realizes recycling and reutilization of the counterweight.

Description

Technical field [0001] The invention relates to the technical field of vehicle counterweights, in particular to a combined counterweight used for detachable recovery of excavators. Background technique [0002] Excavator counterweights on the market are made of welded metal shells filled with a mixture of concrete and ore; or cast iron integrally. Although the counterweight is simple in structure and easy to manufacture, it has a major defect that it is difficult to recycle, causing serious waste of resources and environmental pollution. At present, after the filling type counterweight is scrapped, the cutting method is used to recover the raw materials, while the casting type counterweight needs to be re-melted and cast, which has high cost and low productivity. Summary of the invention [0003] The technical problem solved by the present invention is to provide a combined counterweight for detachable recovery of excavators to solve the above-mentioned problems in the background...
