| This paper based on the background of the large hydraulic supports installation processin Zhaogu No.2Coal Mine of Jiaozuo Coal Group. Respectively researched the large hydraulicsupport disassembly, transportation and installation process. As the largest hydraulic supportin the world, because its supporting height is6.5m, single weight of65tons and workingresistance of18000KN, how to rapid transport, installation in the narrow space andcomplicated environment has become a research focus in this paper.First of all, this paper analyzed the research status of hydraulic support at home and abroadresearch, And on this basis, combined with the actual transport installation environment, putforward is applicable to transport space narrow, limited installation space of transportation ofthe high support, large-tonnage hydraulic support dismantling equipment design; Second,according to the mechanical structure and hydraulic support mine space size, optimized theplan of the hydraulic support unit division method, and according to the unit apart for existingtransportation equipment selection and optimization design. Then, based on the hydraulicsupport disassembly scheme, this paper researched the dismounting machine, auxiliaryequipment of hydraulic support and control process, on the mechanical performance, powerdemand and drive control based on the analysis, design a set of hydraulic support based on thestructure of the overall frame type quick disassembling device. Finally, the article tomanufacture the equipment, and its various functions and overall disassembling performancetest.Through the final actual use, this article design the disassembling of transportationequipment in underground rapid transit, disassembling large hydraulic support requirements,on the basis of reduce the staff labor intensity, improve the enterprise economic benefit, forlarge underground production equipment transportation and installation of equipment research laid a solid foundation. |
