Description

Technical Field

[0001] The utility model relates to the technical field of electrical bridge construction, in particular to a hole opening device for basement electrical bridge construction. Background Art

[0002] Electrical bridges are divided into trough type, tray type, ladder type, grid type and other structures, and are composed of brackets, supports and installation accessories. The bridges can be erected independently in buildings or laid on various buildings and pipe gallery brackets. They should have the characteristics of simple structure, beautiful appearance, flexible configuration and easy maintenance. All parts must be galvanized.

[0003] During the existing cable tray installation process, holes must be drilled using an electric drill, tailored to the site. Due to the cable tray's resilience after bending, drilling requires one person to hold the drill while another operates the electric drill. This method is not only inefficient but also increases labor costs. Furthermore, the drill creates metal burrs at the hole location, which can easily scratch the operator's hands when tightening bolts. To address this issue, we offer a drilling device for basement electrical cable tray construction. Utility Model Content
