Pull rod structure for stacker-reclaimer

Abstract

The invention discloses a pull rod structure for a stacker-reclaimer. The pull rod structure comprises at least one pair of front pull rods and a pair of middle pull rods, and the ends of the front pull rods and the ends of the middle pull rods intersect at one ends of a pair of supporting rods connected to a front arm support of the stacker-reclaimer. Compared with the prior art, the intersectiontype pull rod structure enables force to be distributed and transmitted again by changing the pull rod structure, so that overlarge torsion of the arm support and overlarge relative displacement of the two sides are changed, then deviation of a belt conveyor is reduced, stress on the two sides of a triangular support is uniform, stress of two oil cylinders is also improved, and the two oil cylinders can act synchronously; and in addition, unbalance loading of the rotary upper portion of the machine can be improved, so that wheel pressure distribution of the whole machine is uniform, and stability of the machine is improved.

Description

technical field [0001] The invention relates to a tie rod structure for a stacker-reclaimer, which belongs to the technical field of bulk material transportation. Background technique [0002] At present, stackers and reclaimers are widely used in coal, grain, building materials, chemical industry, electric power and metallurgy industries at home and abroad to stack and retrieve materials. Since the bucket-wheel mechanism of the bucket-wheel stacker-reclaimer sometimes adopts a short-axis structure, the entire weight of the bucket-wheel mechanism is on one side of the arm frame. Originally, the traditional parallel tie rod structure was adopted (such as figure 2 As shown), it will lead to inconsistencies in the force on the left and right tie rods, and the relative displacement of the two sides of the boom will be too large, which will easily cause serious problems such as deviation of the belt conveyor, resulting in unbalanced load on the upper part of the rotation, which ...

Problems solved by technology

Originally, the traditional parallel tie rod structure was adopted (such as figure 2 As shown), it will lead to inconsistencies in the force on the left and right tie rods, and the relative displacement of the two sides of the boom will be too large, which will easily cause serious problems such as deviation of the belt conveyor, resulting in unbalanced load on the upper part of the rotation, which will lead to uneven force on the pitching cylinder and failure of synchronization between the two cylinders , will also increase the load of the hydraulic system, which is easy to damage and increase the purchase cost; at the same time, it will also affect the wheel pressure and stability of the whole machine, and affect the operation of the whole machine
