Abstract

The invention relates to a two-way quick-acting large-flow hydraulic power mechanism, which comprises an interconnected hydraulic actuator and a shaft distribution valve; the hydraulic actuator is a hydraulic cylinder with a double-piston structure, including a cylinder block, a front piston and a rear piston , the front piston and the rear piston are arranged on a piston rod, the cylinder body includes a front cylinder tube and a rear cylinder tube, the front piston is located in the front cylinder tube, and the front cylinder tube is divided into a first working chamber and a second working chamber, and the rear piston Located in the rear cylinder, the rear cylinder is divided into the third working chamber and the fourth working chamber; the shaft distribution valve includes the shaft distribution valve body stator and the shaft distribution valve core rotor, and the shaft distribution valve core rotor is provided with an oil supply channel and a return valve. The oil channel, the oil supply channel and the oil return channel are connected to the external pipeline, and the stator of the shaft distribution valve body and the rotor of the shaft distribution valve core are separated into four sealing areas by the sealing ring from top to bottom. Compared with the prior art, the present invention has the advantages of simplified hydraulic control logic, simple structure, convenient adjustment, convenient rapid reciprocating motion of the piston, and the like.

Description

technical field

[0001] The invention relates to the technical field of hydraulic power mechanisms, in particular to a two-way fast-acting large-flow hydraulic power mechanism. Background technique

[0002] Hydraulic piling hammers are widely used in the foundation construction of prefabricated piles such as bridges, buildings, ports and wharves. Compared with traditional diesel piling hammers, hydraulic piling hammers have the characteristics of high piling efficiency, no exhaust emissions, low noise, etc. Energy, wide adaptability, can be used for underwater piling and inclined pile driving, etc. Pile driving hammers include single-acting hydraulic hammers and double-acting hydraulic hammers. Single-acting hydraulic hammers mean that pile hammers fall freely under the action of their own weight, such as the HH357 series of British BSP and Model 650-3505 hydraulic hammers of American HPSI; The hydraulic hammer, that is, the pile hammer, falls at an acceleration greater than...
