Abstract

The invention discloses a load sensitive control hydraulic system of a pile driver, which comprises a load sensitive multi-way valve, a load sensitive variable pump, a walking motor, a hydraulic hammer, a left oil cylinder, a right oil cylinder, a front oil cylinder, a rear oil cylinder, a variable amplitude oil cylinder, a lifting oil cylinder, a lifting motor, a pilot pump, a pilot valve set and the like, wherein the load sensitive variable pump is connected with the load sensitive multi-way valve; the load sensitive valve controls execution elements such as the walking motor, the hydraulic hammer, the left oil cylinder, the right oil cylinder, the front oil cylinder, the rear oil cylinder, the variable amplitude oil cylinder, the lifting oil cylinder and the lifting motor, and the pilot pump and the pilot valve set control high and low speed switching of the walking motor. The load sensitive control hydraulic system is suitable for the hydraulic system of the road guardrail pile driver, can obviously reduce the power loss of the road guardrail pile driver and improve the work efficiency.

Description

Technical field [0001] The present invention relates to the field of pile driver, and more particularly to a pile driver load-sensitive control hydraulic system. Background technique [0002] The pile driver is an indispensable construction machinery, high efficiency, easy control, and greatly enhances the construction cycle of infrastructure construction and road traffic facilities. The existing pile driver has high production efficiency and low energy loss under specific design conditions, but when the working condition changes, the efficiency is significantly reduced, and the energy consumption is increased. The working environment of the pile driver is very bad, and the working condition is complex and more variable. Therefore, the existing hydraulic system of the pile driver must be improved to ensure that the pile driver can automatically adapt to the variable working condition, which always maintains energy efficiency. Inventive content [0003] In order to overcome the s...
