Concrete road percussion drill protection mechanism
The invention relates to the technical field of percussion drills, in particular to a concrete road percussion drill protection mechanism which comprises a sleeve fixedly connected with a percussion drill, the sleeve comprises a top cylinder, a middle cylinder, a bottom cylinder, an elastic assembly, a connecting assembly, a protection assembly and a fixing assembly, and the top cylinder is fixedly installed on the percussion drill; elastic assemblies are connected among the top cylinder, the middle cylinder and the bottom cylinder, connecting assemblies are connected between the top cylinder and the middle cylinder and between the middle cylinder and the bottom cylinder, when the top cylinder and the middle cylinder move downwards to set positions, the connecting assemblies connect the top cylinder with the middle cylinder and connect the middle cylinder with the bottom cylinder, and protection assemblies are arranged on the inner wall of the middle cylinder and the inner wall of the bottom cylinder. The protection assembly is installed on the top cylinder and used for limiting the springback speed of the elastic assembly driving the top cylinder and the middle cylinder, the fixing assembly is installed on the bottom face of the bottom cylinder, the fixing assembly fixes the bottom cylinder when the elastic assembly is pressed by the top cylinder, the drill bit is kept to move on the same axis all the time in the downward moving process of the concrete road percussion drill, and drill hole deflection is prevented.
本发明涉及冲击钻技术领域，具体为一种混凝土道路冲击钻防护机构，包括与冲击钻固定连接的套筒，套筒包括顶筒、中筒、底筒、弹性组件、连接组件、防护组件和固定组件，所述冲击钻上固定安装有顶筒，所述顶筒、中筒和底筒之间连接有弹性组件，所述顶筒和中筒以及中筒和底筒之间均连接有连接组件，所述顶筒和中筒向下移动至设定位置时连接组件将顶筒与中筒以及中筒与底筒连接，所述中筒和底筒的内壁上均设有防护组件，且防护组件用于限制弹性组件带动顶筒和中筒回弹的速度，所述底筒底面安装有固定组件，且顶筒按压弹性组件时固定组件将底筒固定，实现了在混凝土道路冲击钻向下移动过程中保持钻头始终在同一轴线上运动，防止钻孔偏斜。
