Problems solved by technology

Lake scientific investigations and research experiments often require piling, but due to the limitations of water transportation and the depth of the research area, it is often not possible to use large-scale piling equipment. When there is no light piling machine, manual piling has to be used, which is time-consuming and laborious.

Abstract

The invention discloses a flywheel mechanism for a hammer of a light electric piling machine, which is characterized in that: a blind hole is formed in the middle of the hammer; a horn mouth is formed at the upper opening part of the blind hole; an annular groove is formed at one end of the middle of the blind hole; a hydraulic cylinder which is vertical to an axial line of a drop hammer and is in left-and-right communication with the axial line is arranged on the drop hammer; two pistons are symmetrically installed in the middle of the hydraulic cylinder; each of the two pistons is respectively provided with a same piston rod; each of opening parts at two sides of the hydraulic cylinder is respectively provided with a cylinder cover; each opening part of the hydraulic cylinder is sealed by each cylinder cover; an oil supply hole is formed at the central part of the drop hammer; the oil supply hole is communicated with the middle of the hydraulic cylinder; an oil return hole is respectively formed at each of two sides of the center of the drop hammer; the oil return holes are respectively communicated with piston rod cavities at the left and right sides of the hydraulic cylinder; and a suspension ring is fixedly installed at the top of the drop hammer 1.

Description

technical field [0001] The invention relates to a light electric pile driver, in particular to a hammer head flywheel mechanism of the light electric pile driver, which belongs to the technical field of pile driving machinery. Background technique [0002] Pile drivers are one of the most commonly used machines in civil engineering, from the early steam pile drivers to the current electric pile drivers, but they are relatively large in size and require high-power power drives. carried by large ships. Lake scientific investigations and research experiments often require piling, but due to the limitations of water transportation and the depth of the research area, it is often not possible to use large-scale piling equipment. When there is no light piling machine, manual piling has to be used, which is time-consuming and laborious. Contents of the invention [0003] The object of the present invention is to provide a hammer head flywheel mechanism of a light electric pile dr...
