摘 要 ：本次设计的题目是ZYD600SB 液压静力压桩机的升降行走机构的设计，它主要包括三个部分的内容：主机的设计，液压系统的设计。

The flexible shafts have better strength and rigidity than ordinary level, they are ideal substitute for conventiona level and universaljoint with such merits as : light weight, good flexibility, easily crooking, compact constru—ction, easily installation, good seal, proof rust and anti—deformation, neatly operation.

工作原理：机械操纵系统中的连接部位受力位移时，软轴的芯轴受力，产生往复运动，形成拉力、推力驱使机械作换挡、取力、升降、行走、加油、熄火、制动、转向、换向等工作，它不但优于一般杠杆的强度、刚性而且重量轻、柔性好、可弯曲、结构紧凑、安装方便、密封性好，不易锈蚀变形，操作轻便灵活，是替代传统的连杆、万向节机构的理想产品。

The hoist is fast-acting, has a greater bearing life, and air breathers (94, 96, 98, 100, 102) for the spaces between hydraulic stages, to prevent dirt from being sucked into the hydraulic mechanism.

这种升降装置是快速动作的，轴承寿命较长并且具有用于液压管段之间间隙的通气器（94，96，98，100，102）以防止灰尘被吸入到液压机构中。

Introduce the heavy hammer structure and lock framework with machine combine with solenoid parts of the hydraulic check valve,explatiate on the composing the work principle and character.
