我国自动化驼峰,允许连挂速度低,编组线长,车辆走行阻力离散,作业灵活,要求高解编能力和高度安全可靠,技术难度较大。经过长期努力,现已研究成功多种适合国情的自动化驼峰调速系统,它们是减速器打靶的点式系统、减速器打靶加推送小车或减速顶的点连式系统。本文着重介绍了这些系统的工作原理、设备组成、技术性能、系统设计要点、技术经济效益以及存在问题。三种调速系统各有特点,应当因地制宜地加以选用。至于全顶连续式调速系统,由于不利于提高驼峰解、编能力,使用中问题较多,推广应慎重。
China’s automated hump, allowing even the hanging speed is low, the length of the marshalling line, the vehicle running resistance discrete, flexible operation, requiring a high degree of editing ability and a high degree of safety and reliability, technical difficulty. After long-term efforts, we have successfully researched a variety of automatic hump speed control systems that are suitable for the national conditions. They are spot-type systems for retarder shooting, point-by-point systems for retarder shooting and pushing trolley or retarder. This article focuses on the working principle of these systems, equipment components, technical performance, system design points, technical and economic benefits as well as existing problems. Three speed control system has its own characteristics, should be selected according to local conditions. As for the whole top continuous speed control system, due to not conducive to improving hump solution, editing ability, the use of more problems, promotion should be cautious.
