Pull rod hinged adjustable weight arm of bucket-wheel stacker-reclaimer

Abstract

The invention discloses a pull rod hinged adjustable weight arm of a bucket-wheel stacker-reclaimer. The pull rod hinged adjustable weight arm comprises a tower frame, a pull rod, balance weights A, B, a weight frame, a first drive motor, a second drive motor, a speed reducer and a cantilever rod. One end of the pull rod is hinged to the top end of the tower frame, and the other end of the pull rod is hinged to the cantilever rod. One end of the cantilever rod is hinged to the bottom end of the tower frame, a main weight arm is connected with the other end of the cantilever rod and is provided with a linear guide rail, and the balance weight A can slide along the linear guide rail. An annular weight frame is arranged on the cantilever rod and comprises an annular guide rail, a connecting plate is arranged in the center of the annular guide rail, the balance weight B is in sliding fit with the annular guide rail, the second drive motor and an output shaft of the speed reducer are hinged to the auxiliary balance weight B through a hinge seat, and electromagnets are arranged on the balance weight A and the balance weight B respectively. The pull rod hinged adjustable weight arm is simple in structure and convenient to mount and operate, the eccentric state of the pull rod end of the weight arm is relieved, the left-right overturn troque of a stacker-reclaimer rack can be adjusted, and therefore the stability of the weight arm is improved.

Description

technical field [0001] The invention relates to a loading and unloading device for a bulk material storage yard, in particular to a counterweight arm of a bucket-wheel stacker-reclaimer. Background technique [0002] Bucket wheel stacker reclaimer is an efficient equipment for continuous loading and unloading of bulk bulk materials in modern industry. It has been widely used in ports, docks, metallurgy, cement, steel plants, coking plants, coal storage plants, power plants and other bulk materials (ore, Coal, coke, sand and gravel) storage yard stacking operations. [0003] Bucket wheel stacker and reclaimer can be divided into cantilever type, portal type and bridge type bucket wheel stacker and reclaimer according to the structure and application. Among them, the cantilever bucket wheel stacker-reclaimer has become the most commonly used form at present due to its advantages of flexible working structure, relatively low requirements on the site and wide operating range. ...

AI Technical Summary

Problems solved by technology

The counterweight arm of this structure may have an overturning moment in the left and right directions due to different stacking and reclaiming materials or different working conditions during the working process of the stacker-reclaimer, resulting in instability or a shift in the center of gravity of the entire frame. Job security is not reliably guaranteed
