Abstract

The invention relates to a hydraulic vibropiling hammer box with adjustable eccentricity, structurally characterized in that upper and lower hydraulic motors are in drive connection with upper and lower motor driving wheels respectively through upper and lower driving shafts; upper synchronous tooth A and upper synchronous tooth B are engaged with one side of the upper motor driving wheel in sequence to form an upper engaging portion; lower synchronous tooth A and lower synchronous tooth B are engaged with one side of the lower motor driving wheel in sequence to form a lower engaging portion;the upper synchronous teeth A and B and the lower synchronous teeth A and B are in key connection with upper eccentric blocks A and B and lower eccentric blocks A and B respectively; the upper and lower engaging portions are connected via an eccentricity adjusting mechanism. The hydraulic vibropiling hammer box has the advantages that the eccentricity adjusting mechanism allows stepless torque adjustment; a spiral swing cylinder and a rotary connector can cooperate such that torque adjustment is simpler; front and rear adjusting shafts are split; axial wear pads and roller bearings help improve the axial/radial bearing capacity of the box herein; rigid synchronous wheels are arranged alternately; the designed structure is compact; the eccentricity adjusting mechanism is arranged on the single side so that maintenance is facilitated.

Description

technical field [0001] The invention relates to a hydraulic vibrating piling hammer box with adjustable eccentric moment, in particular to an improved reinforcement mainly suitable for buildings and their foundations, using various steel sheet piles, steel pipe piles and concrete piles for sinking and pulling The utility model relates to a casing of a hydraulic vibration piling hammer with adjustable eccentric moment, which belongs to the technical field of pile machinery. Background technique [0002] Hydraulic piling hammer is a kind of pile sinking and pulling construction machine widely used in urban construction, bridges, ports and other foundation construction projects. It is generally used in conjunction with cranes and pile frames, and is suitable for sinking and pulling 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, and sand piles. Its working principle is: t...
