Problems solved by technology

[0003] Limited by its own conditions, the temporary safety block can only block light weight and large objects, but cannot effectively block people, heavy objects and small objects, so it is surrounded by the opened pit. The "safety block" only plays a warning effect, but does not really play the role of safety block, which belongs to soft protection

Embodiment Construction

[0040] The cover plates in the present invention need to be used in pairs, that is, each pit is covered with two cover plates, and the safety guardrails of each cover plate must not be on the same side.

[0041] Cover plate opening process: Lift the handle (12) on the cover plate (1) with a crane or manpower, and the cover plate (1) drives the safety guardrail (2) and other components to rotate around the rotation axis (6) to open. When the cover (1) is opened to the position perpendicular to the ground, refer to the attached figure 2 , pull out the lock pin (9), and then rotate the safety guardrail (2) around the swivel end to open, see attached image 3 , until it becomes perpendicular to the cover plate (1), and docks with the opposite side of the opened cover plate (1), and finally uses the locking pin (9) on the opposite side cover plate (1) to connect the safety guardrail (2) with the Opposite side covers (1) lock together. Equally, the safety fence (2) on the side co...
