点连式调速系统以其兼有点式和连式两种调速制式的优点,充分发挥两者各自的优势,而成为各种调速制式中的佼佼者,受到运输部门的欢迎,在运输生产中显示着强大的生命力。在满足使用部门要求的前提下,如何减少使用减速顶和减少工程量则是设计工作中不断追求的目标,在这同时,还须克服现有条件的制约,在现有站场许可的情况下,充分利用现有条件。隔段布顶的方法,就是我们在点连式调速系统设计中,解决具体问题时摸索到的一种做法,而又得到充分利用并普遍化了的一种设计方法。 点连式调速系统中线路纵断面一般布置三个大坡段;陡坡,次陡坡和缓坡。三个坡段上缓坡不布置减速顶,陡坡和次陡坡上要布置减速顶的,而且是均匀连续地布置的。所谓隔段布顶,就是在连续布顶中间,出现一个间隔不布顶,即在布顶段中空出一段长度出现两段连续布顶的坡段,这是我们在解决四平站下行编组场点连式调速设计时,挖方受到限制时逼出这么一个方法。
Point-by-point speed control system with its both point-type and connected two kinds of speed control system advantages, give full play to their respective advantages, and become a leader in a variety of speed control system, welcomed by the transport sector, transport Production shows great vitality. How to reduce the use of decelerating tops and reduce the amount of work is the goal pursued in the design work while meeting the requirements of the using department. At the same time, it is necessary to overcome the constraints of the existing conditions and, under the permission of existing stations, , Make full use of existing conditions. Cloth at the top of the method is that we point in speed control system design, to solve specific problems found a way to practice, but has been fully utilized and universal design method. Point-connected speed control system in the vertical section of the general layout of three large slope sections; steep, sub-steep and gentle slope. The slow slope on the three slope sections is not arranged with a decelerating roof, and the decelerating roof is arranged on the steep slope and the sub-steep slope, and is uniformly and continuously arranged. The so-called interval cloth top, that is, in the middle of continuous cloth, there is an interval not cloth top, that is, the length of the top of the cloth in the length of two consecutive sections of cloth appear top slope, which we solve the Siping Station downlink marshalling yard Speed control design, when the excavation is limited to extract such a method.
