AI Technical Summary

Problems solved by technology

The hydraulic hammer for piling engineering with the above-mentioned structure adopts the principle of free fall. Theoretically speaking, the impact force of the piston-cylinder hammer on the pile head is very large, but in actual use, due to various external factors The impact of the piston cylinder hammer on the pile head is only 60% of the theoretical impact. For large-scale construction projects, its hammering force cannot meet the actual needs.

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 construction machinery piling hammer, in particular to an improved invention of a hydraulic piling hammer. 【Background technique】 [0002] In the prior art, piles must be driven in the construction of high-rise buildings and soft soil foundations, and diesel impact hammers have been used in previous piling projects. During pile driving in infrastructure, the noise and exhaust gas of diesel impact hammers have caused serious environmental pollution. The nearby residents, institutions, schools and construction teams are very troubled. In order to solve this problem, the inventor provides a piling hammer that can thoroughly and effectively reduce noise and eliminate exhaust gas, and protect the urban environment. This piling hammer has also applied for a national patent, and its patent number is ZL02158548.2. The technology of this invention The scheme is as follows: "The hydraulic hammer of the pile ...
