The invention discloses a telescopic step missing prevention threshold supporting device, and relates to the technical field of rail transit. The telescopic step missing prevention threshold supporting device comprises a vehicle body; a storage box is fixedly installed in the vehicle body; a driving motor is arranged in the storage box; the driving motor is sleeved with a driving gear block; driven gear blocks are fixedly connected to the front side and the rear side of the driving gear block, and threaded columns are connected into the driven gear blocks in a sleeved mode. According to the invention, a linear motor and a servo motor are started, a supporting base is made to move, the servo motor drives the supporting base to ascend and descend through a second gear block and a gear column, and a first supporting plate and a second supporting plate can be conveniently supported through moving and ascending and descending of the supporting base; the supporting mechanism is stable in operation, simple in structure, convenient to use, and good in supporting effect (a platform is flush with a train threshold); passengers can conveniently carry luggage, and the getting-on and getting-off time of the passengers is shortened.
本发明公开了一种伸缩型防踏空门槛用支撑装置,涉及轨道交通技术领域,包括车体,所述车体的内部固定安装有存放箱,且存放箱的内部设置有驱动电机,所述驱动电机的外部套接有驱动齿轮块,且驱动齿轮块的前后两侧固定连接有从动齿轮块,所述从动齿轮块的内部套接有螺纹柱。本发明中,启动直线电机、伺服电机,直线电机使得支撑底座进行移动操作,伺服电机通过第二齿轮块、齿轮柱带动支撑底座进行升降操作,通过支撑底座的移动升降就方便对第一支撑板、第二支撑板进行支撑工作,该支撑机构运行平稳,结构简单,使用方便,支撑效果好(使得站台与列车门槛齐平),且方便乘客搬运行李,缩短了乘客上下时间。
