Abstract

The invention relates to an automatic folding cover plate structure for a pipeline trench. The automatic folding cover plate includes a support frame and at least one folding cover plate structure; the at least one folding cover plate is arranged on the support frame and covers an opening of the support frame; each folding cover plate includes at least two cover plates and at least one folding mechanism, one of the at least two cover plates is connected to one end of the support frame, and the other cover plates are arranged on the support frame; and each folding mechanism is arranged between two adjacent cover plates. The automatic folding cover plate can achieve automatic folding and unfolding of the at least two cover plates through the folding mechanisms, can be operated by a man, is easy to open and close, and can save time and effort.

Description

technical field [0001] The invention relates to the technical field of pipeline trench construction, in particular to an automatic folding cover plate structure for pipeline trenches. Background technique [0002] Existing pipe ditch cover plates are usually spliced ​​by a plurality of rectangular cover plates, which straddle the edges of both sides of the long pipe ditch. The cover plate is mainly two kinds of patterned steel plate reinforced structure or poured concrete structure in steel frame. When opening the cover plate, multiple manpower or lifting equipment are required to remove the cover plate in sequence, and then build temporary safety protection scaffolding fences around the pipeline ditch. The temporary protective fence and the removed cover cover a large area, hindering the passage of personnel and equipment, and the crosspiece in the middle of the fence blocks the continuity of the operation in the pipeline ditch. After use, remove the fence and assemble ba...
