Description

Technical Field

[0001] The utility model relates to the technical field of pile hammers, in particular to a novel hydraulic and pneumatic composite pile hammer. Background Art

[0002] The existing Chinese patent announcement number is CN215857698U, and the name is a patent for a hydraulic pneumatic composite pile hammer. The background technology of the patent clearly records that "a pile hammer refers to a construction machinery that drives precast piles into the ground. Before piling, the hammer body of the pile hammer needs to be adjusted to the top of the precast pile, and then the precast pile is continuously hammered by the hammer body on the pile hammer to drive the precast pile into the ground. However, the position of the hammer body of the existing pile hammer is fixed. Once there is a deviation between the position of the hammer body and the precast pile, the entire pile hammer needs to be moved to adjust the position of the hammer body, which is very inconvenient to adjust." The patent technical means are solved, but the shortcomings of this technology are: the cylinder can only adjust the lateral position of the pile hammer. When the deviation between the precast pile and the hammer body is a longitudinal deviation, the pile hammer cannot be adjusted to the precast pile. Utility Model Content

[0003] The utility model aims to provide a novel hydraulic pneumatic composite pile hammer, which drives a first threaded rod to rotate through a first motor, thereby driving a hammer body to perform lateral adjustment, and then drives a second threaded rod to rotate through a second motor, thereby driving a hammer body to perform longitudinal adjustment, so that the hammer body is aligned with a precast pile.
