Drill rod structure for core drilling detection of foundation pile
The invention discloses a drill rod structure for core drilling detection of a foundation pile, and relates to the technical field of building sampling, in particular to the drill rod structure for core drilling detection of the foundation pile. The drill rod structure comprises a drill rod main body and an upper mounting frame, a central transmission rod is fixedly mounted at the top of the drill rod main body, and a driven gear fixedly sleeves outside the central transmission rod; a lower mounting frame is movably mounted outside the central transmission rod, the upper mounting frame is located above the drill rod main body, and a mounting rod is movably mounted in the upper mounting frame. According to the drill rod structure for core drilling detection of the foundation pile, the drill rod structure is mounted on a driving assembly through the mounting rod, when the driving assembly drives the drill rod main body to rotate, cooling water can be injected into an inner water flowing channel along a first-stage water inlet pipe, a center connecting pipe and a second-stage water inlet pipe, and the cooling water is discharged along a water outlet hole in the bottom of an abrasion-resistant connecting ring, so that the cooling water directly acts on the heating position of a drill bit, the heat dissipation effect on the drill bit is improved, and the drill bit is prevented from being damaged due to overheating.
本发明公开了用于基桩钻芯检测的钻杆结构，涉及建筑取样技术领域，具体为用于基桩钻芯检测的钻杆结构，包括钻杆主体、上安装架，所述钻杆主体的顶部固定安装有中心传动杆，且中心传动杆的外部固定套装有从动齿轮，所述中心传动杆的外部活动安装有下安装架，所述上安装架位于钻杆主体的上方，所述上安装架的内部活动安装有安装杆。该用于基桩钻芯检测的钻杆结构，通过安装杆将该钻杆结构安装在驱动组件上，在驱动组件带动钻杆主体转动时，可沿一级进水管、中心连接管、二级进水管向内流水道内部注入冷却水，并使冷却水沿耐磨连接环底部的出水孔排出，使冷却水直接作用在钻头发热处，提高对钻头的散热效果，防止钻头过热损坏。
