一种锅炉钢架的高强度箱型截面支撑结构

Abstract

本实用新型涉及支撑结构技术领域，公开了一种锅炉钢架的高强度箱型截面支撑结构，包括底截面支撑架、一号延伸支撑架和二号延伸支撑架，所述一号延伸支撑架和二号延伸支撑架的下端面靠近四角处均固定连接有连接柱。本实用新型中，通过在两个相邻的支撑架之间设置装卸结构，能够依据锅炉数量灵活调整支撑组件数量，无论是单台锅炉的独立支撑，还是多台锅炉的组合支撑需求，均可快速适配，显著提升支撑结构的通用性与工程应用灵活性，同时支撑架上设置的可调节间距夹持机构，可针对不同口径的锅炉进行精准定位与稳固支撑，避免因锅炉尺寸差异导致的支撑不稳问题，有效扩大了支撑结构的适用范围。
