Electric bucket wheel stacker-reclaimer with servo driving linkage mechanism

Abstract

The invention discloses an electric bucket wheel stacker-reclaimer with a servo driving linkage mechanism. A bucket wheel cantilever pitching device comprises a first rack pitching mechanism and a second rack pitching mechanism, wherein the first rack pitching mechanism is a double-linkage mechanism and comprises a first rocker rod and a first connecting rod; the second rack pitching mechanism is a four-linkage mechanism and comprises a second rocker rod, a second connecting rod and a second swing rod; a rack is supported by the first rack pitching mechanism and the second rack pitching mechanism; bucket wheels are mounted at the front end of a bucket wheel cantilever, the rear end of the bucket wheel cantilever is hinged to the front of the rack, the front cantilever body of the bucket wheel cantilever is stayed to the top of the rack through a traction rope, and a counterweight mechanism is arranged at the rear of the rack; the first rocker rod and the second rocker rod are respectively driven by a first rocker rod servo motor and a second rocker rod servo motor which are arranged on the rack. The electric bucket wheel stacker-reclaimer has the advantages of programmable output control, flexible path, large adjustable angle, large work space and the like.

Description

(1) Technical field: [0001] The invention relates to port loading and unloading machinery, in particular to an electric bucket-wheel stacker and reclaimer with a servo-driven linkage mechanism. (two) background technology: [0002] Bucket wheel stacker and reclaimer is a new type of high-efficiency continuous loading and unloading machine, mainly used in bulk storage yards such as bulk cargo terminals, steel plants, thermal power plants and mines, to complete the storage of iron ore, coal, sand, etc. , Digging and equalizing operations, has the advantages of large radius of gyration, uniform feeding, stable operation, etc., and has been widely used. However, in the existing bucket-wheel stacker-reclaimer products disclosed in CN1616329A, CN102358520B, CN101823631A, CN101678971B, CN101817453A, etc., the steel structure and the cantilever beam are all driven by a single-degree-of-freedom hydraulic cylinder or wire rope traction to realize the adjustment of the pitch angle. Th...
