Description

Technical Field

[0001] The utility model relates to the technical field of highway maintenance, and in particular to a telescopic highway maintenance and repair guardrail early warning device. Background Art

[0002] After a highway has been in use for a period of time, it often needs maintenance due to the large number of vehicles traveling on the highway. In addition to the maintenance and repair of the highway as a whole, it is sometimes also necessary to repair the guardrail in the middle of the highway.

[0003] When existing staff repair highway guardrails, in order to protect the staff, they generally fence off the area around the guardrail to be repaired, and then put up warning signs on the outside of the fence near the direction of the vehicle to prevent passing vehicles from not noticing the abnormal situation and causing traffic accidents. However, this warning method requires multiple warning signs to be operated simultaneously. At the same time, in order to make the warning signs more obvious, it is often necessary to provide a certain power supply for the warning signs. This increases the amount of warning devices that the staff must carry when repairing the guardrail, making it inconvenient for the staff to repair the guardrail more easily. It also increases the repair time of the staff, making the highway at the repair location unsmooth and easily affecting traffic. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the utility model is to provide a telescopic highway maintenance and repair guardrail early warning device, which effectively solves the problem that the existing early warning equipment requires workers to carry more devices.
