摘要

中心立柱下部回转平台位于圆形料场堆取料机立柱支腿上方

是上部堆料机与下部取料机等旋转的基础

也是设备运行过程中的主要受力部件

承受着各主要部件的质量及设备运转过程中产生的动载荷

因此对其焊接工艺和组装工艺要求极为严格。分析某圆形料场堆取料机中心立柱下部回转平台的使用及结构特点

重点讨论下部回转平台在制造过程中的焊接技术及关键部位的质量控制

总结出一套合理的焊接工艺。实践证明

该工艺可有效地控制下部回转平台的焊接变形

保证焊接质量

为整机设备的安全使用奠定基础。

Abstract

Lower rotary platform which is above leg support of circular stockyard stacker is basic unit of rotary to upper stacker and lower stacker. The lower rotary platform is main unit in bearing weight and support weight and dynamic loading of device when circular stockyard stacker is working

so its quality is very strict in welding. In this paper

reasonable welding technology method of quality control for main unit is summed up according to feature of structure of central rotary platform in circular stockyard stacker. Practice has proved that the reasonable welding technology may control effectively deformation of welding and ensure quality of welding

thus laying the foundation for the safe use of the whole machine.
