Abstract

The invention discloses a high frequency hammer pile hydraulic system of a hydraulic hammer pile machine. The high frequency hammer pile hydraulic system of the hydraulic hammer pile machine comprises a hydraulic pump, a cover plate valve group and an electromagnetic valve group, wherein an oil suction input end of the hydraulic pump is connected into an oil tank, the cover plate valve group is connected with a hammering oil cylinder and controls the stretching action of the hammering oil cylinder, the cover plate valve group comprises three cover plate valves, a first oil port of a first cover plate valve and a first oil port of a second cover plate valve are connected in series and are connected to the hydraulic pump, a first oil port of a third cover plate valve and a first oil port of a fourth cover plate valve are connected in series and are connected to a rodless cavity of the hammering oil cylinder, a first oil port of a fifth cover plate valve and a first oil port of a sixth cover plate valve are connected in series and are connected to a rod cavity of the hammering oil cylinder, and the electromagnetic valve group comprises three electromagnetic valves to control the on / off of the cover plate valves. The invention aims at providing the high frequency hammer pile hydraulic system of the hydraulic hammer pile machine to meet the two-way high-frequency on / off of an hydraulic oil way and guarantee the smoothness of the oil way, in addition, the high frequency hammer pile hydraulic system of the hydraulic hammer pile machine is efficient and stable, and the working efficiency is improved. The invention further discloses a hammering cartridge valve of the hydraulic hammer pile machine, integrated with the cover plate valve group, the electromagnetic valve group and the related oil path of the hydraulic system.

Description

technical field [0001] The invention belongs to the field of construction machinery, and relates to a high-frequency hammer pile hydraulic system of a hydraulic hammer pile machine and a hammer pile insertion valve integrated with main pipelines of the system. Background technique [0002] In the application of modern construction engineering, in order to prevent uneven settlement of buildings, as well as enhance stability and earthquake resistance, for the foundation of buildings, the common method is to drive ground piles as the foundation of buildings, and ground piles require special hammer pile machines , which are generally powered by hydraulic pressure. [0003] Mini hammer pile driver is a kind of hammer pile equipment suitable for construction sites with limited space. Its structural features are suitable for small construction sites, especially self-built residential buildings, small high-rise buildings, factory buildings, or space floors. Its structure is light a...
