看到《矿山机械》1982年第9期关于南宁冶金矿山机械厂试制成功Z—17B型无钢丝绳装岩机一文的报导后,受到很大启发。矿山使用装岩机时,稳定钢丝绳对设备的使用性能确实影响很大,为此,我们把Z—20B型电力装岩机改成圆弧型齿轮齿条传动代替稳定钢丝绳。从1972年开始,就进行过一些调查和收集用户反映。经过比较分析认为,改成圆弧 Seeing “Mining Machinery” No. 9 of 1982 on the successful trial of Nanning Metallurgical Mining Machinery Factory Z-17B type wire rope rock loader reported a great inspiration. Mine use rock loader, the stability of the wire rope does a great impact on the performance of the equipment, therefore, we Z-20B electric rock loader into a circular gear rack instead of stable wire rope. Since 1972, some surveys have been conducted and user feedback collected. After comparative analysis, into a circular arc
