Auxiliary locking device for railway vehicle door
The invention discloses a rail vehicle door auxiliary locking device which comprises a rack installed on a vehicle body, a hanging frame installed on the rack, a rail arranged on one side of the hanging frame, a lead screw driven by a motor and a transmission nut arranged on the lead screw in a sleeving mode. The transmission nut is connected with a transmission frame, the transmission frame is connected with a transmission plate, and the other side of the transmission plate is connected with a bearing support. The bearing bracket is slidably connected with the track; a synchronous rod parallel to the lead screw is arranged on the rack and sleeved with a lock fork and a cam, a roller matched with the lock fork is arranged on one side of the transmission nut, and a roller matched with the cam is arranged at the front end of the bearing support; in the locking state, the roller at the front end of the bearing support is clamped below the rail, and in the unlocking process, the cam ejects the roller at the front end of the bearing support out, and unlocking is achieved. According to the scheme, the driving part is separated from the locking part, the locking part mechanically limits the rolling wheel, under the condition that the driving part loses efficacy, the rolling wheel is not ejected out of the rail, locking failure cannot occur, and the locking reliability is remarkably improved.
本发明公开了一种轨道车辆门辅助锁闭装置，包括安装在车体上的机架，安装在机架上的挂架，挂架一侧设有轨道，通过电机驱动的丝杆及套设在丝杆上的传动螺母，传动螺母连接传动架，传动架连接有传动板，传动板另一侧连接有承载支架，承载支架滑动连接轨道；机架上平行于丝杆设置有同步杆，同步杆上套设有锁叉和凸轮，传动螺母一侧设有滚轮与锁叉相配合，承载支架前端设有滚轮与凸轮相配合；锁闭状态下，承载支架前端滚轮卡死在轨道下方，解锁时，凸轮将承载支架前端滚轮顶出，实现解锁。本方案将驱动部分与锁闭部分分离，锁闭部分通过对滚轮的机械限位，在驱动部分失效的情况下，滚轮未被顶出轨道，就不会锁闭失效，显著增加了锁闭的可靠性。
