Main and auxiliary span circular yard

Abstract

The invention discloses a main and auxiliary span circular yard which is designed mainly for increasing the storage amount of the yard on the basis that civil engineering and equipment investment is reduced. The main and auxiliary span circular yard comprises a plurality of supporting columns arranged at intervals in an annular structure, an arc-shaped main span shed is supported on the supporting columns, a first annular moving rail is arranged on the outer sides of the upper portions of the supporting columns, a second annular moving rail is arranged on the ground on the periphery of the supporting columns, a material pushing machine is disposed between the first annular moving rail and the second annular moving rail, and the material pushing machine moves along the annular structures. According to the main and auxiliary span circular yard, under the condition that the height of a material pile is not changed, the storage amount of raw materials of the circular yard can be increased, civil engineering and equipment investment is reduced, design difficulty is reduced, and reliability of equipment and safety of a material shed structure are improved.

Description

technical field [0001] The invention relates to a main and auxiliary spanning circular stock yard. Background technique [0002] The circular stockyard is to transport various foreign materials according to certain requirements and stack them to the designated position of the stockyard through the stacker, and according to the requirements of each user, the material is taken by the portal scraper reclaimer and conveyed through the belt. The machine conveying system is transported to each user. [0003] Such as figure 1 As shown, in the prior art, the central part of the circular material yard with main and auxiliary cross-circular stockyards is provided with a central funnel at the lower part of the ground. The head of the center column is fixed on the corridor at the top of the center column. The stacker is on the upper part of the reclaimer. The stacker is fixed on the center column and rotates around the center column. The stacker is stacked by a cantilever belt conveyo...

AI Technical Summary

Problems solved by technology

[0004] It can be seen that the raw material storage has a great relationship with the diameter E of the circular stockyard and the height of the retaining wall. In order to increase the raw material storage of the circular stockyard, many enterprises increase the stockpile height F under the condition of constant The diameter E of the shed, but the size of the diameter E is restricted by the span of the reclaimer and the structural design of the shed; if the span of the reclaimer is too large, the investment in equipment will be too large, and the reliability of the equipment will also be reduced , if the diameter E of the material shed is too large, it will also increase the design difficulty and civil construction investment of the material shed, and the safety of the material shed will also be reduced
