摘　　要：随着液压支架发展,液压支架制造技术和稳定性有了较大提升,液压支架在井下工作年限越来越长,支架的高度也越来越高。在支架大修中,铰接轴的拆卸是其中最重要的一环,铰接轴无法顺利拆卸直接影响后续的大修。大修任务中铰接轴的拆卸工作难度越来越大,双作用液压支架铰接轴拔轴装置的研制可以很好地解决这一矛盾。With the development of the hydraulic support,the manufacturing technology and stability of the hydraulic support have been greatly improved.The working life of the hydraulic support in the underground is longer and longer,and the height of the support is also higher and higher.In the bracket overhaul,the disassembly of hinge shaft is the most important part.The failure of the disassembly of hinge shaft directly affects the subsequent overhaul.The disassembly of the articulated shaft in the overhaul task is becoming more and more difficult.The development of the double acting hinge shaft pulling device of the hydraulic support can well solve this contradiction.
