[0002] Expressways are high-grade roads, which refer to roads that can accommodate an annual average day and night passenger car traffic volume of more than 25,000 vehicles, are specially designed for high-speed driving of cars in separate lanes, and have full access control. For sections of expressways with more severe surrounding terrain, guardrails will be installed on both sides of the road to provide certain safety protection for cars when driving and to prevent cars from falling directly in the event of an accident. Currently, guardrails are mainly transported to highway construction sites by transport vehicles.

[0003] Corrugated guardrails are generally made of galvanized steel plates. For roads with longer mileage, the length of the guardrails required to be installed is also extended accordingly. Therefore, a larger number of guardrails need to be transported. However, in the process of transporting the guardrails to the construction section by transport vehicles, some guardrails are prone to fall off the transport vehicles, posing a threat to the safety of the surrounding environment. In addition, the frame height of the transport vehicles is usually high. When unloading the corrugated guardrails one by one, if manual operation is used, the labor intensity is high and the unloading efficiency is low.

[0004] Based on this, a device for automatically loading and unloading corrugated guardrail plates is now provided, which can eliminate the disadvantages of the existing devices. Utility Model Content
