AI Technical Summary
Technical Problem
Existing foundation drilling equipment experiences horizontal vibrations during drill rod rotation, resulting in frequent and severe vibrations that affect drilling accuracy and equipment lifespan.
Method used
The system employs a structure including a calibration damping component, a shock absorber, a rotating arm, and an elastic limit clamp. By limiting the horizontal sway of the transmission shaft, it reduces the vibration of the drilling equipment. Combined with an inclination adjustment component, it improves the flexibility of drilling angle adjustment.
Benefits of technology
It effectively reduces the vibration frequency and noise of the equipment, improves the stability and drilling accuracy of the equipment, and extends the service life of the equipment.

Abstract
The utility model discloses foundation drilling equipment damping device, including base assembly, still include calibration damping assembly, the front of base assembly is provided with calibration damping assembly, the inside of calibration damping assembly is provided with drilling assembly, the rear end of drilling assembly is provided with lift adjustment assembly, the rear end of lift adjustment assembly is provided with inclination angle adjustment assembly, and base assembly includes base, the both sides lower extreme of base all are provided with shock absorber, the front of base is provided with calibration frame, the rear of the upper end of calibration frame is fixedly provided with the slide, and the rear end of slide is provided with adjustment support arm. The utility model utilizes two rotary arms and elastic spacing clamp to limit the rotation of the transmission shaft in the inside, effectively prevents the horizontal swing problem of transmission shaft, because the horizontal swing of transmission shaft is limited to reduce the transmission shaft to the drilling impact probability on horizontal direction, and then reduces the probability of equipment vibration, reduces the noise and equipment stability decline influence that the vibration brings.
