Technical Field

[0001] The invention belongs to the technical field of traffic protection, and in particular relates to a ground trough type lifting protection device. Background Art

[0002] On the railway platform, there are almost no protective devices near the edge of the railway track. People often slip off the platform accidentally or fall intentionally, causing casualties. At present, trains cannot be controlled as accurately as subways and cannot start and stop accurately at designated locations. They cannot use gate-type guardrails like subway platforms and can only rely on platform managers for control. However, such human control has little effect. Some places have installed liftable fence-type protective devices. There is no prompt during the rising and falling process. During the descent, it is easy to crush pedestrians' feet, posing a certain threat to pedestrians' safety. Summary of the invention

When it is raised, it can effectively block passage, making it more difficult for intentional passage. When it is lowered, it is flush with the ground to ensure passage. The lifting is quick and convenient without affecting passage. The safety vertical bars are used for coordination, which can protect the railings on the one hand and reduce the spacing between the safety vertical bars on the other hand. No cross bars are provided, which can prevent the cross bars from pressing on the feet of pedestrians during landing, thereby reducing safety hazards. The coordination structure of the railings and the safety vertical bars can avoid casualties caused by slipping or rolling.

[0019] 2. The trough-type lifting protection device of the present invention adopts a fixed column, which, on the one hand, prevents the railing from shaking, and on the other hand, serves as a warning to point out the existence of the lifting railing, and an electronic display screen can be set on it to prompt the status of the railing in advance.

[0020] 3. The safety vertical bar of the trough type lifting protection device of the present invention is fixed to the base by a round tube spring piece. The provision of the round tube spring piece is to facilitate the free fall of the safety vertical bar when it is damaged without affecting the normal operation of other safety vertical bars. A cover plate is provided on the top of the safety vertical bar, which, on the one hand, plays a shielding role to prevent debris from falling into the trough, and on the other hand, plays a positioning role for the safety vertical bar to prevent the position of the safety vertical bar from shifting.
