Abstract

This invention discloses a hydraulic pile hammer including an outer long cylinder, a hydraulic cylinder, an oil stored cylinder and a pile hammer, in which, said hammer is set in the outer long cylinder, a piston is set in the hydraulic cylinder, a second piston is set in the oil cylinder, said two pistons are connected by a piston rod characterizing that said hydraulic cylinder is set above the outer long cylinder, a spray oil cylinder is set under the oil stored cylinder and they are connected and the cavity of the connection is filled with oil, the section of the spray is smaller than that of the stored one, a third piston is set in the spray cylinder and connected with the hammer by a push rod.

Description

【Technical field】 [0001] The invention relates to an improved invention of a piling hammer for construction engineering machinery, in particular to an improved invention of a hydraulic piling hammer. 【Background technique】 [0002] In the prior art, the construction of high-rise buildings and soft soil foundations must be piling. In the past, diesel impact hammers were used for piling projects. When piling in infrastructure, the noise and exhaust gas of diesel impact hammers caused serious environmental pollution. Nearby residents, institutions, schools and construction teams are very troubled. In order to solve this problem, the inventor provides a piling hammer that can completely and effectively reduce noise, eliminate exhaust gas, and protect the urban environment. The piling hammer has also applied for a national patent, and its patent number is ZL02158548.2. The plan is as follows: "The hydraulic hammer for piling engineering is driven by the i...
