研制交分道岔旷量消除装置

大编组站、旅客站和其他用地长度受限制的咽喉区大多采用交分道岔,但交分道岔也是故障多发处所。在其故障发生的概率中,交分道岔旷量引起的表示杆卡口失去表示的故障占了很大的比重。天津电务段研制的交分道岔旷量消除装置,在对原道岔连接销功能分解的基础上,增加了"消除旷量"的"潜在"功能。阐述了消除道岔旷量的3种方案及其利弊分析,详细介绍了道岔旷量消除装置的原理、构成和功能。

The slip switches are mostly yard for big marshalling yard, passenger station and other places with restricted throat length and malfunctions often occur to them. The occurrence of missing of indication caused by the clearance of calipers jaws of slip switches account for great proportion in the number of malfunctions. The slip switch elimination clearance device, developed by the division of Tianjin C＆S, increases the potential functions of clearance elimination over the decomposition of connection pin of the switch, The paper expounds three schemes of eliminating turnout＇s clearance and makes analysis of advan- tages and disadvantage with detailed explanation of the theory, composition and function of slip switch eliminate device.
