Abstract

The invention relates to a hydraulic vibration pile hammer with adjustable eccentricity. The key structure is an eccentric adjustment mechanism, the mechanism is arranged on the left side of the interior of a vibration exciter box, the front and back sides of the eccentric adjustment mechanism are connected with front end eccentric adjustment teeth and back end eccentric adjustment teeth through flat keys, an eccentric rotating mechanism is arranged on the right side of the eccentric adjustment mechanism of the vibration exciter box, the eccentric rotating mechanism is engaged with the front end eccentric adjustment teeth and the back end eccentric adjustment teeth, power driving parts are upper and lower hydraulic motors arranged on the surface of the vibration exciter box, and the upperand lower hydraulic motors are connected with the eccentric rotating mechanism. The hydraulic vibration pile hammer has the advantages that (1) the eccentric adjustment mechanism achieves electrodeless torque adjustment, a common hydraulic cylinder is matched with a bearing set, and the torque adjusting manner is stable and reliable; (2) real-time adjustment of the eccentricity is achieved, resonance avoiding in the starting and stopping stages is guaranteed, noise and resonance harms on the equipment and surrounding environments are reduced, and the service life is prolonged; and (3) rigid synchronizing wheels are arranged in stagger, and the design structure is compact. A large lead spline is adopted, and the loading capacity is high.

Description

technical field [0001] The present invention relates to a hydraulic vibrating piling hammer with adjustable eccentric moment, in particular to an improved reinforcement for buildings and their foundations, which can be used for sinking and pulling operations by using various steel sheet piles, steel pipe piles and concrete piles. The utility model relates to a hydraulic vibration piling hammer with eccentric moment adjustment, which belongs to the technical field of pile engineering machinery. Background technique [0002] Hydraulic vibratory piling hammer is a pile sinking and pulling construction machine widely used in various foundation construction projects such as urban construction, bridges, and ports. It is generally used in conjunction with cranes and pile frames. It is suitable for sinking and pulling operations of various steel sheet piles and steel pipe piles. It can also be used for various types of foundation operations such as concrete pouring piles, lime piles...
