旋挖钻机液压伺服系统系统是其操纵控制的中枢,直接影响其操纵控制能力。我公司在开发HR35型旋挖钻机的液压伺服系统时,分析了操纵旋挖钻机时易发生的安全问题,采取了有针对性的安全措施,取得良好的操纵、使用效果。1.液压伺服系统结构驾驶员座椅两侧的操纵手柄是液压伺服系统控制核心。我们为HR35型旋挖钻机选用力士乐4TH6E70-1X/YU23(YU43)型操纵手柄。该手柄具有动作轻便、反应灵敏、可进行复合动作的操纵等特点。但如果在液压伺服系统的设计中未能很好地利用这些特点,在旋挖钻机
Rotary drilling rig hydraulic servo system is the center of its manipulation and control, a direct impact on its ability to manipulate control. When developing the hydraulic servo system of HR35 rotary drilling rig, our company analyzed the safety problems that occurred easily when manipulating the rotary drilling rig, adopted the targeted safety measures and achieved good operation and use effects. 1. Hydraulic servo system structure The driver’s seat on both sides of the control handle hydraulic servo system control core. We selected the Rexroth 4TH6E70-1X / YU23 (YU43) joystick for the HR35 rotary drilling rig. The handle has a light action, responsive, can be manipulated and other characteristics of the composite action. However, if the hydraulic servo system design can not make good use of these features, rotary drilling rig
