Circular yard stacker and reclaimer

Abstract

The invention discloses a round stockyard stacking and fetching machine which comprises a rotating portal portion, a bucket wheel fetching portion, a conveying portion and a centering swinging mechanism. The rotating portal portion rotates around the centering swinging mechanism by taking span of the rotating portal portion as a radius, the bucket wheel fetching portion and the conveying portion are connected with the rotating portal portion, and the conveying portion is composed of multiple belt conveyors and cooperates with the bucket wheel fetching portion to form a fetching logistics channel and / or a stacking logistics channel. Different from existing equipment, the round stockyard stacking and fetching machine takes the span of a portal as actual working range radius, and application of the stacking and fetching machine in a round stockyard is realized for the first time.

Description

technical field [0001] The invention relates to a stacker and reclaimer used in a circular stockyard, more specifically, to a circular stockyard stacker and reclaimer, and belongs to the technical field of circular stockyard bulk material stacking and reclaiming equipment. Background technique [0002] With the increasing awareness of environmental protection and environmental protection requirements, reducing the pollution to the surrounding environment has become an urgent problem to be solved in large modern storage yards. At the same time, it is also necessary to avoid the impact of bad weather on the safe operation of the storage yard. Circular stockyard stacker and reclaimer is a kind of stacking and reclaiming equipment for bulk materials, usually arranged in circular stockyards. With economic development and social progress, environmental protection requirements are getting higher and higher. Circular stockyard stackers and reclaimers The application of feeder will b...

Problems solved by technology

Although the production efficiency of reclaiming has been improved by setting up two sets of simultaneous reclaiming in two layers, but in a large number of practices, several defects of this kind of equipment have also been exposed: (1) limited by the scraper driving mode and The limitation of structural size restricts its production capacity. Under the current technology, its maximum reclaiming production capacity can only reach 3000m in the form of double scraper arm structure. 3 / h; (2) The scraper reclaimer is not suitable for use in the environment of relatively viscous materials, and the problem of viscous materials sticking to the scraper has not been well resolved; (3) The scraper reclaimer is not suitable for materials with large particle size and lumps In the case of too much material, the size of the material is too large and the block material is too large to easily damage the scraper and the scraper chain

Because the lifting beam of the bridge-type side scraper reclaimer is at the bottom of the material yard, the bucket wheel reclaiming operation must be assisted by the structural characteristics of the material rake, resulting in the following limitations in actual use: (1) Since the lifting beam is fixed on the walking device , the cantilever scraping device is mainly at the lower end of the material pile, and the angle between the cantilever scraper device and the material pile is adjusted by the pitching device hinged at the middle and upper part of the cantilever, and it is impossible to realize multi-dimensional reclaiming of the bucket wheel reclaiming part , which limits the ability of retrieving materials; (2) Since the height direction of the main girder is fixed, the scraper device of the cantilever moves back and forth along the length direction of the main girder to reclaim materials repeatedly, so that the unloading device cannot achieve targeted crossing of the material pile Reclaiming; (3) due to its structural limitations, the retrieving hopper can only stack the same material, and it is impossible to stack a variety of different materials at the same time in the same stockyard

However, circular stockyards cannot achieve layering and stacking and reclaiming materials across stockpiles, so it is impossible to store multiple materials in one stockyard, and it is also impossible to realize cross-span access to multiple materials in the same stockyard
