Description

Technical Field

[0001] The utility model relates to the technical field of concrete guardrail drilling, in particular to a bridge concrete guardrail drilling positioning device. Background Art

[0002] During the construction of bridge guardrails to install sound insulation screens, it is usually necessary to use a pistol drill to drill holes in the concrete guardrails of the bridge. The pistol drill drilling process is generally carried out manually, and the drilling accuracy of the pistol drill mainly depends on the technical proficiency of the operator.

[0003] In the current construction process of drilling holes in concrete guardrails of bridges, low drilling accuracy is prone to occur when workers simply rely on handheld pistol drills to drill holes. When using traditional drilling auxiliary positioning devices, they are usually fixed to the concrete guardrails with bolts, so that the pistol drill is fixedly installed on the auxiliary positioning device and drilling is performed. Both the pistol drill and the positioning device are fixedly installed, which is not convenient for up, down, left, and right displacement adjustment, thereby reducing the flexibility of the drilling construction.

[0004] In view of the above problems, an innovative design is carried out on the basis of the original punching and positioning device. Utility Model Content
