Description

Technical Field

[0001] The utility model relates to the technical field of highway construction, in particular to a portable detecting device for the central height of the cross beam of a corrugated beam guardrail. Background Art

[0002] In highway construction, due to the certain rigidity and toughness, good sight guidance function, good coordination with the road alignment, and beautiful appearance of the corrugated beam steel guardrail, it is usually set on both sides of the road, ensuring that vehicles driving on the road can drive out of the lane in case of an accident and reducing the degree of injury of the driver, providing safety guarantee for the safe and efficient driving of highway vehicles.

[0003] Currently, the common method for detecting the central height of the cross beam of the corrugated beam steel guardrail is that a detector holds a spirit level. When detecting a double-wave corrugated beam steel guardrail, one end of the spirit level is placed between two wave peaks. When detecting a triple-wave corrugated beam steel guardrail, one end of the spirit level is placed at the center position of the second wave peak of the triple-wave corrugated beam steel guardrail. Then, observe whether the horizontal bubble on the spirit level is leveled. After leveling the spirit level, the state of the detector holding the spirit level remains unchanged. Then, another detector measures the distance from the road surface to the lower part of the spirit level with a steel tape, which is the central height of the cross beam of the corrugated beam guardrail at this place. Through a large number of acceptance detections, it is found that this detection method has a large subjective factor of human. It is very difficult to identify that one end of the spirit level held by hand is placed at the center position of the wave peak. Often due to the experience of the detector and the reason of the detection method, the measured detection data is different, and the operation is complex, requiring the cooperation of multiple people, which is not convenient enough, thus affecting the measurement efficiency.
