The invention relates to the technical field of rail transit, and discloses a rail transit platform screen door cab apron placing device. The device comprises a base, a platform screen door and a vehicle door; sliding blocks are symmetrically installed on the two sides of the platform screen door, sliding sleeves are fixedly connected to the lower ends of the sliding blocks, and threaded rods are connected to the inner sides of the sliding sleeves in a sleeving mode; the tail end of the threaded rod is fixedly connected with a first gear, the first gear is meshed with a second gear, and the left side of the second gear is fixedly connected with a cab apron. Rotary placement of the cab apron is automatically achieved by opening the shielding door, the effect of automatically placing the cab apron is achieved, and the problems that manpower and material resources are consumed when workers manually place the cab apron, and the taking efficiency is low are solved; meanwhile, through cooperative arrangement of a limiting rod, a limiting rod, a conducting strip and an electromagnet, upward movement of a limiting plate is achieved, then the effect of preventing the wheels from slipping backwards is achieved, the problem that in the prior art, due to the fact that the cab apron is obliquely placed, the wheels slip backwards is solved, and the riding safety of passengers is remarkably improved.

    本发明涉及轨道交通技术领域,且公开了一种轨道交通用屏蔽门渡板放置装置,包括底座和屏蔽门以及车门,所述屏蔽门的两侧对称安装有滑块,所述滑块的下端固定连接有滑套,所述滑套的内侧套接有螺纹杆,所述螺纹杆的末端固定连接有第一齿轮,所述第一齿轮啮合有第二齿轮,所述第二齿轮的左侧固定连接有渡板。本发明通过屏蔽门的开启自动实现渡板的转动放置,达到自动化放置渡板的效果,解决了工作人员手动放置渡板耗费人力物力、搭乘效率低下的问题,同时通过限位杆、限位杆、导电片、电磁铁之间的配合设置实现对限位板的上移进而到达防止车轮倒溜的效果,解决了现有技术因渡板斜向放置发生的车轮倒溜的问题,显著提高乘客的乘车安全。
