Hinged column type double-pull-rod cantilever stacker

Abstract

The invention discloses a hinged column type double-pull-rod cantilever stacker. The hinged column type double-pull-rod cantilever stacker comprises an upper steel structure, a portal base frame, a rotation device, a pitching device, a traveling device, a belt conveyor system, a cab device, a tail-car device and a material transferring device. The upper steel structure comprises a vertical column, a balance weight pull rod, a balance weight arm, a balance weight, a cantilever beam and cantilever pull rods, wherein the vertical column is vertically hinged to the front end of the cantilever beam through a hinged shaft I; one ends of the cantilever pull rods are fixed to the cantilever beam, the other ends of the cantilever pull rods are fixed to the vertical column, and a cable-stayed structure composed of the vertical column, the cantilever beam and the cantilever pull rods is formed; the balance weight is supported and fixed to the lateral face, opposite to the extending direction of the cantilever beam, of the vertical column through the balance weight pull rod and the balance weight arm, and the balance weight pull rod, the balance weight arm and the vertical column jointly form a triangular supporting system. By the adoption of the technical scheme, the bottom of the vertical column has no bending moment through the hinged arrangement of the vertical column and the balance design of a balance weight mechanism and a cantilever beam fixing mechanism, and the safety of the whole steel structure is improved at the same time.

Description

technical field [0001] The invention relates to a cantilever stocker, in particular to a hinged column double-tie rod cantilever stocker. Background technique [0002] The cantilever stacker is an advanced and efficient bulk material handling equipment, which is used to load and unload bulk materials such as coal and ore raw materials. [0003] At present, regardless of double tie rods or single tie rods, the upright column and the lower side of the stacker are of an integrated structure, and the bending moment is large. In order to ensure the strength, the lower structure of the upright column has large dimensions, heavy weight, and high power of the running and slewing mechanisms. Moreover, due to the large bending moment of the column, this model is prone to the problems of fracture and fatigue damage at the lower part of the column. [0004] Therefore, developing a new type of cantilever stacker to solve the problems of high power of the running and turning mechanism, l...
