为了研究大倾角工作面液压支架的稳定性问题,从支架移架过程中顶板的稳定性出发,建立支架带压移架时的受力机理模型,通过脱离体受力平衡理论,分析支架在擦顶前移过程中支柱残余支撑力,并结合葛亭煤矿2331工作面ZF5600/16.5/26液压支架自身参数进行具体计算。另外,从四连杆机构孔轴配合的角度分析顶梁横向偏移对支架残余支撑力的影响,并对这种影响,提出擦顶移架过程中通过改变支架自身结构要素来提高支架横向稳定性的措施,保证大倾角液压支架能够适应工作面安全采煤的需要。
In order to study the stability of the hydraulic support in steep working face, based on the stability of the roof in the process of moving the support, the force mechanism model of the support with the pressure support is established. By analyzing the force balance theory of the support, In the process of roof displacement, the residual support force of the column was calculated and calculated according to the parameters of the ZF5600 / 16.5 / 26 hydraulic support at 2331 face of Geting Coal Mine. In addition, the influence of the lateral displacement of the top beam on the residual support force of the support is analyzed from the perspective of the cooperation of the four-link mechanism hole axis. In addition, the influence of the lateral displacement of the top beam on the residual support force of the support beam is analyzed, and the lateral stability of the support is improved by changing the structural elements of the support Sexual measures to ensure that hydraulic stents with large dip angle can meet the need of safe coal mining in face.
