摘 要

捣固车用在铁道线路的新线建设,旧线大修清筛和运营线路维修作业中,对轨道进行拨道、起道抄平、石渣捣固及道床石渣的夯实作业,使轨道方向、左右水平和前后高低均达到线路设计标准或维修规则的要求,提高道床石渣的密实度,增加轨道的稳定性,保证列车安全运行。捣固车已经成为铁路建设维护不可缺少的重要工程设备。但在捣固车的实际应用中也有一些问题,比如能耗大,效率低,温升高,尤其是高温升的问题直接影响了捣固车的液压系统的正常工作。本次设计也就是专门针对捣固车以上的问题对其液压系统进行的改进性设计,比如对效率低的元件进行重新选型,在功率损失大的元件部位安装散热器件,此外还做了些系统优化的设计,如去掉了一些功能上重复,多余的元件。在设计工作中对原液压系统的泵系统进行了重新的选型计算。通过一定的技术经济性分析,本次改进设计基本达到了预期的目标,改进后系统的散热问题得到解决,取得了一定的效果。

Abstract

Tamping machine used in the new line railway line construction, overhaul the old-line screen and operation of line maintenance operations, on track to allocate Road, copied from Ping Road, carbide tamping and ballast carbide consolidate the operations so that the orbit Direction, and around about the level of both high and low lines to the design standards or rules of the maintenance requirements, improve the density of carbide bed, increasing the stability of the track and ensure safe operation of trains. Tamping machine maintenance of railway construction has become an important and indispensable engineering equipment. But in the practical application of tamping machine also has some problems, such as energy consumption, low efficiency, temperature rise, in particular the problem of high temperature or a direct impact on the tamping machine of the normal work of the hydraulic system. The design is specific to tamping machine over the issue of its hydraulic syst
