Belt conveyor steel structure online replacement method

HUANG HONGXING

The invention discloses a belt conveyor steel structure online replacement method. The belt conveyor steel structure online replacement method comprises the following steps that (1) the belt conveyorsteel structure is disassembled according to the original steel structure of a belt conveyor; (2), during machine stopping, construction is gradually conducted from the tail of the belt conveyor to the head of the belt conveyor, the horizontal steel structure disassembled in the step (1) is fit to the inner side of the original horizontal steel structure, welding and strengthening are conducted section by section according to a steel structure drawing of the belt conveyor till a molded steel structure, same with the steel structure drawing, is formed in the original steel structure; and (3) after the new steel structure is fixed, the original steel structure is dismantled, and accordingly, replacement of the belt conveyor steel structure is completed under the no stopping condition. According to the belt conveyor steel structure online replacement method, under the no stopping condition, within the short stopping period of the belt conveyor every day, the belt conveyor steel structureis integrally replaced by adopting partial segmented welding forming, stable operation of production is not influenced, and the belt conveyor steel structure online replacement method is a very simpleand practical belt conveyor steel structure replacement method.

本申请公开了一种皮带机钢结构在线更换方法，包括以下步骤：1)根据皮带机原有钢结构，对皮带机钢结构进行分解；2)利用停机时间，从皮带机尾部逐步向皮带机头部进行施工，将步骤1)拆分好的水平钢结构紧贴原有水平钢结构内侧，按照皮带机钢结构图纸进行分段焊接、加固，直到在原有钢结构内部形成钢结构图纸结构一样的成型钢结构；3)将新的钢结构固定好后，拆除原有钢结构，从而在不停产的情况下完成了皮带机钢结构的更换。本发明皮带机在线更换方法，在不停机的情况下，利用皮带机每天短时的停机时间，通过采用局部分段焊接成型，最后对皮带机钢结构整体实现更换，不影响生产的稳定运行，是一种非常简单且使用的皮带机钢结构更换方法。
