重庆单轨交通关节型道岔的控制电路原理

重庆单轨是我国引进的第一条单轨制式交通线路,由于其线路及道岔的特殊性,道岔转辙设备采用的是电动液压控制系统及行程开关,带动整体钢箱梁或PC梁动作,这与普通地铁轮轨道岔设备完全不同.该道岔控制电路参考了日本单轨信号系统道岔控制电路,并根据国内联锁系统的道岔控制基本原理进行了设计和完善;以五开道岔为例,介绍道岔控制电路的3种模式及动作程序,3种模式分别为联锁系统进路控制、车站值班员手动控制及现场人工控制.

Principles of Control Circuit for Joint Turnouts in Chongqing Monorail Transit

The monorail in Chongqing City was the first one introduced to China. Because of the particularity of the monorail and its turnouts, electro-hydraulic control system and process control switches, which are different from other subway turnout equipment, are used for turnouts, driving the steel girder or PC girder to move as a unit. The turnout control circuit for Chongqing monorail transit was designed and perfected using Japanese monorail signal system and the principles for turnout control in the domestic interlocking system as reference. Citing five-position turnouts as examples, three models and working process of the control circuit of turnouts are described, The three models include interlocking system control, manual control by shift foreman and manual control on site.
