Redundant drive closed chain bucket wheel stacker reclaimer

Abstract

The invention discloses a redundancy driving closed-chain bucket wheel stacker reclaimer. A bucket wheel overhanging arm elevating device comprises a parallelogram mechanism and a support rod which are arranged on a vehicle frame, wherein the parallelogram mechanism comprises a front rocker and a rear rocker which are arranged under the parallelogram mechanism, as well as a front connecting rod and a rear connecting rod which are arranged above the parallelogram mechanism; the lower ends of the front rocker and the rear rocker are hinged to each other on the vehicle frame; the lower ends of the front connecting rod and the rear connecting rod are respectively hinged to the upper ends of the front rocker and the rear rocker and the upper ends of the front connecting rod and the rear connecting rod; the lower end of the support rod is hinged to the vehicle frame; the rear bottom part of the vehicle frame is hinged to the upper end of the support rod, and the front bottom part of the vehicle frame and a hinge point of the front connecting rod and the rear connecting rod form a compound hinge manner; the rear end of the bucket wheel overhanging arm is hinged to the front part of the vehicle frame, and an arm body at the front part of the bucket wheel overhanging arm is slantways pulled to the top of the vehicle frame through a pulling rope, and a balancing weight mechanism is arranged at the front part of the vehicle frame; the front rocker, the rear rocker and the support rod are respectively driven by a front rocker electric motor, a rear rocker electric motor and a support rod electric motor which are arranged on the vehicle frame. The bucket wheel stacker reclaimer disclosed by the invention has the advantages of high positioning accuracy, large carrying capacity, large adjustable angle, flexibility in output, and the like.

Description

(1) Technical field: [0001] The invention relates to port loading and unloading machinery, in particular to a redundantly driven closed-chain bucket wheel stacker and reclaimer. (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. There are shortcom...

AI Technical Summary

Problems solved by technology

[0003] For this reason, the present invention proposes a redundantly driven closed-chain bucket wheel stacker and reclaimer, which mainly solves the problem of limited working space, less flexible output, high processing and assembly requirements, short service life, and oil leakage of traditional bucket wheel stacker and reclaimers. and other technical issues
