针对8.8 m大采高液压支架大缸径立柱材料空白,现有加工制造装备等难以满足用户要求的现状,在架型设计、支架中心距确定、立柱缸径选定与制造、高强钢材料开发与焊接工艺研究等方面进行研究,最终确定了ZY26000/40/88D架型,支架中心距达到2.4 m,立柱缸径φ600 mm,并形成了优选的加工制造工艺,有效保证了产品品质,与钢厂合作开发了ZMJ06高强钢材料,屈服强度达到890MPa,有效减小了支架质量,整架质量控制在100 t以内。目前8.8 m液压支架已经顺利通过了国家实验室型式试验检测,效果良好,为下一步批量生产做好了技术储备。

According to the status of a cutting height 8.8 m hydraulic powered support existed no material of the large diameter cylinder leg, available processing a nd manufacturing equipment and others would hard to meet the requirements.A study was conducted on the powered support type set up, the powered support central d istance determination, the leg cylinder diameter selection and manufacturing, the high strength steel material development and welding technique study and other aspe cts. Finally, the ZY26000/40/88 D mode powered support was determined, the central distance of the powered support was 2.4 m and the cylinder diameter of the lag W as φ600 mm. An optimized processing and manufacturing technique was formed to effectively ensure the product quality. The ZMJ06 high strength steel material was joi ntly development with steel company. The yield strength was 890 MPa, would effectively reduce the weight of the powered support and the total weight of the powered s upport could be controlled within 100 t. At present, the 8. 8 m high cutting hydraulic powered support was successfully passed the test of the national certification organ ization and the excellent effect had made a good technical reservation for the late batch production.
