永煤集团车集煤矿大部分煤巷均采用掘进机进行掘进,在施工过程中,掘进机电缆随着掘进机前进或后退,始终在底板上被来凹拖动,为消除因电缆拖地造成的隐患,设计出一套掘进机电缆架空拖动装置。1存在问题(1)掘进机电缆在底板上被来回拖动时,如底板有水或其它尖锐物体,长时间以来会造成电缆进水或被刺破,产生漏电、跳电事故,影响正常的安全生产。(2)掘进机不断的前进和后退,会造成电缆经常被转载机跑车压烂,以致电缆漏电,从而使工作面发生
During the construction process, the boring machine cable was moved forward and backward along with the boring machine, and was always dragged on the floor to be concave. In order to eliminate the problem caused by dragging of the cable Of the hidden dangers, designed a TBM overhead cable drive device. 1 problems (1) boring machine cable is dragged back and forth on the floor, such as the floor with water or other sharp objects, for a long time will cause the cable into the water or was punctured, resulting in leakage, jump accident, the impact of normal Safe Production. (2) The continuous advance and retreat of the roadheader will cause the cable to be often crushed by the sports car of the reprint machine, causing the cable to leak electricity, so that the work surface may occur
