Road wave-shaped guardrail plate stacking and destacking chain conveying device

The utility model relates to the technical field of chain conveying devices, in particular to a road wave-shaped guardrail plate stacking and destacking chain conveying device which comprises a fixing frame, a conveying mechanism arranged in the fixing frame and a connecting piece connected between the fixing frame and the conveying mechanism. The fixing frame comprises symmetrically-distributed fixing plates, supporting plates fixed to the two ends of the bottoms of the fixing plates and connecting plates fixed between every two adjacent supporting plates. When the corrugated guardrail plate conveying mechanism conveys corrugated guardrail plates, the corrugated guardrail plates are placed between every two adjacent clamping blocks, the corrugated guardrail plates are conveyed in a limited mode through the two clamping blocks, the corrugated guardrail plates can be prevented from sliding on the conveying mechanism, and stable conveying of the corrugated guardrail plates is facilitated; the push rod motor ext
