According to the child protective device for the subway platform, the structure is simple, through driving of the motor, the protective door is automatically opened and closed, and convenience andrapidness are achieved; the getting-on time cannot be influenced, during waiting for a train, children can be effectively prevented from falling off onto a rail, and thus the safety is improved; andduring getting-on, the rotary door can block gaps in the two sides, thus falling-off is prevented, the pedestal falls so that feet can be prevented from being clamped, meanwhile, personal belongings can be prevented from falling in the rail, the loss is reduced, and safe operation of the train is also ensured.

Description

technical field [0001] The invention relates to a protective device, in particular to a child protective device for a subway platform, and belongs to the technical field of transportation. Background technique [0002] The subway is a kind of urban rail transit, which refers to the urban rail transit system that mainly runs underground. It is a large-capacity rail transportation system that uses a steel wheel and rail system and mainly operates in tunnels built in the underground space of large cities. When conditions permit, it can also go out of the ground and run on the ground or on the viaduct. According to the different models selected, it can be divided into conventional subways and small-section subways; according to different scales, it can be divided into high-capacity subways and large-capacity subways. subway. [0003] At present, many cities have built subways, which are popular among the general public for their convenience and speed. However, some subway platf...
