悬挂式轨道梁与道岔梁间锁定补偿机构

Integrated Locking Compensation Mechanism between Suspended Track Beams and Turnout Beams

[目的]为了补偿悬挂式单轨交通系统中移动式道岔在轨道梁与道岔梁接口之间预留的转辙安全缝隙,实现道岔转辙到位的可靠锁定,提高列车通过岔区时的安全性及旅客舒适度,提出一种梁间锁定补偿一体化机构,即锁定与补偿功能共用一处动力源,实现道岔转辙到位后先锁定再补偿的时序要求。[方法]介绍了悬挂式单轨道岔的应用现状及主要存在的问题,并对其应用场景进行了分析;介绍了悬挂式轨道梁与道岔梁的梁间锁定补偿机构的设计组成,并对该机构的运动工作原理进行了分析。[结果及结论]所提锁定补偿机构整体外形结构尺寸紧凑,能够满足悬挂式单轨移动式道岔梁与轨道梁之间狭小的安装空间。该机构通过一体化连杆的空间布局设计实现了梁间的可靠锁定、道岔梁与轨道梁间的接缝补偿,以及满足了锁定与补偿两处功能先锁定再补偿的时序要求。

[Objective]To compensate for the preset turnout safety gap between track beam and switch beam of the mobile turnout in the suspended monorail transit system,ensure reliable locking when turnout is in place,and improve the safety and passenger comfort when train passing through turnout area,an integrated mechanism for locking and compensation is proposed,where the locking and compensating functions share a common power source,meeting the sequential requirements for locking before compensation after the turnout is in place.[Method]The current application status of suspended monorail turnouts and the main existing problems are introduced,and the application scenarios are analyzed.The design composition of the locking and compensation mechanism between the suspended track beam and the turnout beam is presented,along with an analysis of the motion working principle of the mechanism.[Result&Conclusion]The proposed locking and compensation mechanism has a compact overall external structure,meeting the installation space constraints between the suspended monorail mobile turnout beam and the track beam.Through the spatial layout design of the integrated linkage rod,the mechanism achieves reliable locking between beams,seam compensation between the turnout beam and the track beam,and fulfills the sequential requirements for locking before compensation.
