Ground groove type lifting protection device

Abstract

The invention discloses a ground groove type lifting protection device. The device comprises a ground groove, a liftable handrail located in the ground groove, a safety vertical rod synchronously lifting with the handrail and a driving mechanism used for driving the handrail to ascend and descend. A handrail base is arranged in the ground groove, the handrail is connected to the handrail base through a movable supporting rod, the movable supporting rod is movably connected with the handrail and the handrail base, and the driving mechanism controls the handrail to ascend or descend. A pluralityof safety vertical rods are arranged on one side of the handrail, the safety vertical rods and the handrail jointly form a protection structure, the bottoms of the safety vertical rods are fixed to the base, a plurality of frames are arranged between the base and the handrail, and when the handrail descends, the base is pushed to descend through the frame. The upper end of the frame is fixed to the handrail, the bottom of the frame is movably connected to a base, and the base is fixed into the ground groove through the spring. Casualty accidents caused by slipping and rolling can be avoided,and great guarantee is provided for passenger safety.

Description

technical field [0001] The invention belongs to the technical field of traffic protection, in particular to a trough-type lifting protection device. Background technique [0002] On the train platform, there are almost no protective devices near the edge of the train track, and people often slip or fall off the train platform accidentally, causing casualties; at present, the train cannot be controlled as precisely as the subway, but Accurately start and stop at the designated location, so you can’t use the door-type guardrail of the subway platform, and you can only rely on the management of the platform to control it. However, such human control can have little effect; some places have set up liftable Fence-type protective device, the device does not prompt during the ascent and descent process, and it is easy to press the pedestrian's feet during the landing process, which poses a certain threat to the safety of pedestrians.
