[0002] Metal guardrail is a product with very flexible assembly. It is mainly used for the protection and maintenance of personal safety and equipment facilities in residential, highway, commercial areas, public places and other occasions. It has the characteristics of strong impact resistance, beautiful appearance and corrosion resistance. When installing and constructing metal guardrail, the guardrail needs to be punched, and then a punching device is needed.

[0003] When drilling holes in existing metal guardrails, workers use handheld punches to directly drill holes in the guardrails. However, the surface of the metal guardrails is smooth, and direct drilling can easily cause the drill bit and the guardrail to slip, making it impossible to locate the drilling position of the drill bit, resulting in low drilling efficiency and easy accidents due to slipping, which is inconvenient to use. Therefore, we have proposed a metal guardrail drilling device to solve the above problems. Utility Model Content

The first bracket 1 and the second bracket 2 are connected by a guide mechanism;

[0031] During the construction of the metal guardrail, when it is necessary to punch a hole in the guardrail, the punching device is moved so that the guardrail is located between the first clamping block 5 and the second clamping block 6. The position of the lifting frame 4 is adjusted by the adjustment mechanism to make the second clamping block 6 move toward the first clamping block 5. The guardrail is clamped by the first clamping block 5 and the second clamping block 6 to fix the punching device and the guardrail. Then, the punching motor 12 is started, and the punching motor 12 drives the drill bit 13 to rotate. The second bracket 2 is pushed toward the first bracket 1 through the handle 14, and then the drill bit 13 is driven to move toward the guardrail to drill a hole in the guardrail. Through the punching device, the punching device and the guardrail can be relatively fixed when punching a hole in the guardrail, and then the drill bit 13 can be positioned to avoid the drill bit 13 from deviating during drilling. This not only improves the drilling efficiency, but also can stabilize the drilling and avoid accidents due to slipping of the drill bit 13 and the guardrail.
