Description

Technical Field

[0001] The utility model relates to the technical field of guardrail installation, in particular to a drilling device for installing road and bridge guardrails. Background Art

[0002] Guardrails are fences. The guardrails here refer to industrial guardrails. Guardrails are mainly used for the protection and protection of personal safety and equipment facilities in residential areas, roads, commercial areas, public places and other occasions. Guardrails can be seen everywhere in our lives. The price per meter of guardrails will vary depending on the height. Different types of guardrails undertake different protection tasks. Road and bridge guardrails are special guardrails used on roads or bridges.

[0003] Currently, when installing guardrails, most holes are drilled using handheld punches such as electric hammers or handheld drills. This cannot effectively ensure that the depth of each hole is consistent, resulting in an unstable installation of the guardrail, posing a potential safety hazard. Furthermore, the holes cannot be guaranteed to be perpendicular to the road surface. Therefore, we propose a drilling device for road and bridge guardrail installation. Utility Model Content
