摘　　要：设备列车是综采工作面上重要的辅助运输设备,能够实现工作面上相关配套设备的长距离运输。然而,传统设备列车采用钢丝绳牵引工艺,在煤矿井下大坡度的运输过程中易发生自滑移、溜车、钢丝绳断裂等事故,存在严重的安全隐患。为适应大坡度的工况,研制一种新型自移设备列车组,基于该设备列车建立其在大坡度下的受力数学模型,并对其关键元部件抱闸机构进行有限元分析,满足设备列车在±12°坡度的正常使用,充分发挥其安全高效的优势。The equipment train is an important auxiliary transportation equipment on the fully mechanized mining face,which can realize the long-distance transportation of related supporting equipment on the face.However,the traditional equipment train adopts wire rope traction technology,which is prone to self sliding,car sliding,wire rope breakage and other accidents during the transportation of large slope in the coal mine,and there are serious potential safety hazards.In order to adapt to the working conditions of large gradient,a new type of self-moving equipment train set was developed.Based on the equipment train,the mathematical model of its stress under large gradient was established,and the finite element analysis of its key component,the holding brake mechanism was carried out to meet the normal use of the equipment train at±12°gradient,giving full play to its advantages of safety and efficiency.
