摘　　要：针对现有煤矿井下锚杆钻车抓网速度慢,铺网效率低,参与人员多等问题,根据智能化锚杆钻车的基本要求,提出了一种智能化锚杆钻车自动抓网装置的设计方案。根据锚网属性,采用多直流电磁铁均匀分布吸网模式实现锚网的自动抓取。基于SolidWorks对抓网装置进行了三维建模,以确定各构成单元之间的工作协调性。通过理论计算获得了直流电磁铁的相关参数,为选择电磁铁提供理论依据。基于ANSYS Workbench有限元仿真平台分析了直流电磁铁吸合面处于不同位置时对锚网的吸力大小,验证了理论计算和布局方式选择的正确性。最后,搭建了实验平台,对自动抓网装置技术方案进行了实验验证。结果表明:电磁铁位置布局设计合理,吸力大小满足锚网稳定抓取及自由移动的技术要求。According to the basic requirements of the intelligent rock bolt drill truck,a design scheme of the intelligent rock bolt drill truck automatic mesh grabbing device is proposed to solve the problems of the existing coal mine rock bolt drill truck,such as slow mesh grabbing speed,low mesh laying efficiency,and many participants.According to the properties of the anchor mesh,multi DC electromagnets are used to uniformly distribute the mesh suction mode to realize the automatic grasping of the anchor mesh.Based on SolidWorks,the three-dimensional modeling of the net grabbing device is carried out to determine the work coordination between the constituent units.The relevant parameters of DC electromagnet are obtained through theoretical calculation,which provides a theoretical basis for the selection of electromagnet.Based on the finite element simulation platform of ANSYS Workbench,the suction of the DC electromagnet on the anchor net when the suction surface is at different positions is analyzed,which verifies the correctness of the theoretical calculation and the selection of the layout mode.Finally,an experimental platform is built to verify the technical scheme of the automatic net catching device.The results show that the position layout of the electromagnet is reasonable,and the suction meets the technical requirements of stable grasping and free movement of the anchor net.
