液压支架是目前机械化采煤中主要的支护设备,为满足其承载更高工作阻力的要求,立柱中缸在设计过程中普遍选用高强度、厚壁钢管加工制成。为保证产品质量,提高厚壁缸管焊接接头强度,对立柱中缸的焊接接头形式在传统接头结构基础上进行大胆改进,通过工艺试验及严格的工艺评定,设计出科学、合理的焊接接头形式,并确定切合实际的坡口参数。
Hydraulic support is the main support equipment in mechanized coal mining at present. In order to meet the requirement of bearing higher work resistance, the column cylinder is generally made of high strength and thick-walled steel pipe in the design process. In order to ensure product quality and improve the strength of welded joints of thick-walled cylinder tubes, the welding joint form of the cylinder in the upright column is boldly improved on the basis of the traditional joint structure. Through scientific experiments and rigorous process qualification, a scientific and reasonable welding joint form , And determine the actual groove parameters.
