Description

Technical Field

[0001] This utility model relates to the technical field of corrosion resistance testing technology, and in particular to a corrosion resistance testing device for high-strength steel corrugated beam guardrails. Background Technology

[0002] With the continuous increase in traffic flow and vehicle speed, the requirements for the safety performance of guardrails are also becoming increasingly stringent. High-strength steel corrugated beam guardrails, due to their excellent impact resistance and corrosion resistance, are widely used in traffic facilities such as highways and bridges. However, in harsh environments such as humidity and salt spray, the corrosion resistance of guardrails becomes a key factor affecting their service life and safety performance. Therefore, a corrosion resistance testing device for high-strength steel corrugated beam guardrails has emerged.

[0003] For example, in a prior art represented by application number CN202323176939.7, the main structure includes a support frame and a test chamber. The test chamber is mounted on the support frame, and a discharge port is located on the right side of the test chamber. By activating an electric push rod, the base plate lifts the high-strength steel corrugated beam guardrail out of the corrosive solution. Subsequently, workers push a push plate to pass the high-strength steel corrugated beam guardrail through the discharge port on the base plate, thus preventing the corrosive solution from splashing onto the workers when removing the high-strength steel corrugated beam guardrail.

[0004] During use, it was found that the existing high-strength steel corrugated beam guardrail corrosion resistance testing device requires manual pushing, which can easily cause operator fatigue. Furthermore, in corrosion resistance testing, samples often need to be dried at different test stages to remove surface moisture or simulate a dry environment. The existing high-strength steel corrugated beam guardrail corrosion resistance testing device is inconvenient for drying the high-strength steel corrugated beam guardrail, resulting in reduced accuracy of test results. Therefore, there is an urgent need for a new high-strength steel corrugated beam guardrail corrosion resistance testing device. Utility Model Content
