The invention discloses a hydraulic integral integrated valve block, and belongs to the technical field of hydraulic elements of pneumatic hydraulic hammer systems of
engineering machinery. The hydraulic integral integrated valve block is characterized by comprising an
oil supply flow passage, high-pressure energy accumulator connectors,
oil supply control valve connectors, a hydraulic oil cylinder connector, an oil supplement valve connector, oil return control valve connectors, an oil return flow passage and low-pressure energy accumulator connectors. According to the hydraulic integral integrated valve block, all components of the hydraulic
system of a pneumatic hydraulic hammer are integrated into a whole through an oil flow channel and an
oil distribution cavity inside, so that the use of connecting pieces is reduced, then the hammer
body system is compact in structure, the oil way structure is simplified, on-way loss and local loss of most oil are avoided, and efficient transmission and utilization of hydraulic energy are realized. According to the hydraulic integral integrated valve block, an oil supplementing device is arranged between the oil return flow passage and the
oil distribution cavity, then the function of supplementing oil into a hydraulic oil cylinder in the
inertia lifting stage of a
pile hammer is realized, and thus the problem that the striking energy isreduced due to the fact that too large pressure pulsation is generated in the
hydraulic cylinder is avoided. All parts of the hydraulic
system are arranged in the hydraulic integral integrated valve block, then direct contact between the parts and the external construction environment is avoided, and thus the service lives of all the parts are indirectly prolonged.
