Abstract

The invention relates to a large-impulse hydraulic power mechanism based on shaft distribution, which includes a hydraulic actuator and a shaft distribution valve connected to each other; the hydraulic actuator is a hydraulic cylinder with a double-piston structure, including a cylinder body, 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 and a rear cylinder. The front piston is located in the front cylinder, which divides the front cylinder into a first working chamber and a second working chamber. The rear piston is located in In the rear cylinder, the rear cylinder is divided into the third working chamber and the fourth working chamber; the axial distribution valve includes the stator of the axial distribution valve body and the rotor of the axial distribution spool, and the rotor of the axial distribution spool is provided with an oil supply channel and an oil return Channels, oil supply channels and oil return channels are connected to external pipelines, 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 sealing rings from top to bottom. Compared with the prior art, the present invention has the advantages of simplified hydraulic control logic, simple structure, convenient adjustment, fast reciprocating movement 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 large-impulse hydraulic power mechanism based on shaft flow distribution. 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 accelerat...
