Abstract

The invention discloses a hydraulic static pile driver and a hydraulic control system thereof.The hydraulic control system comprises a multi-way valve main valve, a fast pressure valve set, a fast return valve set, a main pressure oil cylinder and an auxiliary pressure oil cylinder, the fast pressure valve set is integrally arranged on the main pressure oil cylinder, and the fast return valve set is integrally arranged on the auxiliary pressure oil cylinder; the multi-way valve main valve is connected with the fast pressure valve set, and the multi-way valve main valve is connected with the fast return valve set. According to the hydraulic control system, the integrated arrangement of the multi-way valve main valve and the hydraulic valve group can be realized, so that the pipeline arrangement can be simplified, the operation labor intensity can be reduced, the energy consumption can be reduced, the working efficiency can be improved, the pressure grade of the system is high, and the high-pressure development requirement of equipment can be met.

Description

technical field [0001] The invention relates to the technical field of hydraulic control, in particular to a hydraulic control system. The invention also relates to a hydraulic static pile driver with the hydraulic control system. Background technique [0002] Hydraulic static pile driver is widely used foundation construction equipment, its core hydraulic control components include multiple manual multi-way control valves such as piling multi-way valve, travel multi-way valve, outrigger multi-way valve, confluence valve group, discharge Multiple decentralized control valve groups such as oil valve group. [0003] When the hydraulic system in the prior art is under fast pressure conditions, the oil return from the small cavity of the cylinder first passes through the long pipeline, then passes through the internal fast pressure connection of the multi-way valve, and then returns to the large cavity of the cylinder through the long pipeline, resulting in relatively large pre...
