Abstract

The invention belongs to the technical field of piling machinery construction equipment of mechanical engineering and civil engineering, machinery parts and transmission devices and discloses a hydraulic system for a hydraulic pile hammer. The hydraulic system for the hydraulic pile hammer comprises a double-wall hydraulic cylinder (6), a hydraulic slide valve (5), a loading valve (1), a two-position four-way control valve (2), a low-pressure energy accumulator set (3), a hydraulic hammer travel switch set (4), a high-pressure energy accumulator set (7) and a power source. An integrated structure is adopted by the hydraulic system provided by the invention; the pipeline length and the possible bend are reduced; the linear loss is greatly reduced; and the effect is more obvious especially under the conditions of large flow and high pressure.

Description

technical field [0001] The invention belongs to the technical field of pile machinery construction equipment, mechanical parts and transmission devices of mechanical engineering and civil engineering, and relates to a hydraulic system of a hydraulic piling hammer with large striking energy, fast striking frequency and comprehensive utilization of energy. Background technique [0002] Human beings have a long history of understanding and utilizing piles and pile foundation engineering. Archeology has discovered piles in ancient cultural sites in Chile, which are about 12,000 years old; in the Hemudu site in Yuyao, Zhejiang, and the Banpo Village site in Xi'an, Shaanxi, it can be seen that people have penetrated tree poles into the soft soil layer 7,000 years ago In order to support the original form of buildings, in the long process of human history, the types and techniques of pile foundations have been greatly developed and changed. The piles can be divided into wooden pil...
