摘要
针对矿山运输领域广泛使用的窄轨工矿电机车溜车事故频发、制动距离长以及闸瓦易磨损等问题,详细分析了现有单侧基础制动装置的结构和原理,提出了一种双侧基础制动装置方案。经过结构优化,增大了制动倍率和制动力,增大了闸瓦与踏面的接触面积,从根本上消除了轴承偏磨现象。现场使用证明,该装置有效解决了溜车现象,缩短了制动距离,减小了闸瓦磨损,提高了制动可靠性。
In view of frequent sliding,long braking distance and easy wearing of brake shoe in the narrow-gauge industrial and mining electric locomotive broadly used in mining and transportation field,the paper analyzed the structure and principle of current single-side foundation brake rigging in detail,and proposed the scheme of a double-side foundation brake rigging.After the structural optimization,the brake rigging got larger braking leverage,braking force as well as contact area between the brake shoe and the tread,which eliminated the wearing of eccentric bearing radically.The spot application showed that the scheme effectively avoided the sliding,shortened the braking distance,reduced the wearing of braking shoe and improved the braking reliability.
