AI Technical Summary
When the drill barrel of an existing core drilling machine rotates at high speed, it oscillates out of center due to centrifugal force, which can cause core samples to break, become eccentric, or have uneven surfaces. It is also prone to lateral swinging upon initial contact, which affects the accuracy of test data, accelerates equipment wear, and shortens the service life.
A limiting and stabilizing device is adopted, including a jacket assembly and a control mechanism. The clamping frame and rolling elements form a stable clamp on both sides of the drill barrel, reducing swaying and swinging. Combined with an elastic sealing gasket, it prevents dust intrusion and achieves stable limiting of the drill barrel.
It effectively reduces the misalignment and lateral swaying during high-speed rotation of the drill barrel and the lateral swaying at initial contact, thereby improving the quality of core sampling, extending equipment life, and reducing maintenance costs.
