The invention belongs to the technical field of rail transit equipment, and relates to a quick tightening device for a through passage; the main structure of the quick tightening device comprises a tightener, a left rope, a right rope, a snap ring, a damper and a limiting rope; the tightener is connected with one end of the left rope and one end of the right rope respectively, and the other ends of the left rope and the right rope are connected with the snap ring respectively; the snap ring is connected with the damper and the limiting rope, is located in the through channel at the joint of two carriages, can adapt to position changes generated by relative movement between vehicles during train coupling based on the flexibility characteristic of the snap ring, can rapidly and reliably fold the through channel during unpacking, greatly shortens the operation time, relieves the labor intensity of operators, and improves the operation efficiency; the quick tightening device is simple in structure and convenient to operate; the tightener drives the pull rope to tighten and release the through channel, and the requirement for quick tightening and releasing of the through channel is met; meanwhile, the effect of stabilizing the through channel during unlocking is achieved, and technical support is provided for intelligent marshalling of trains.

    本发明属于轨道交通设备技术领域,涉及一种贯通道用快速收紧装置,主体结构包括收紧器、左绳索、右绳索、卡环、阻尼器和限位绳,收紧器分别与左绳索和右绳索的一端连接,左绳索和右绳索的另一端分别与卡环连接,卡环与阻尼器和限位绳连接,位于两节车厢连接处的贯通道内部,基于自身的柔性特性,在列车连挂时能适应车辆间的相对运动而产生的位置变化,解编时能够对贯通道实现快速可靠的收起,大大缩短操作时间,减轻操作者劳动强度,提高运营效率;其结构简单,操作方便,通过收紧器带动拉绳对贯通道进行收紧和释放操作,满足贯通道的快速收紧和释放的要求,同时具备解锁时稳固贯通道的作用,为实现列车智能化编组提供技术支持。
