摘要
通过研究液力变矩叉车传动特性,研制出一套可实现液力变矩叉车缓动功能的控制装置。该装置通过检测操纵手柄位置,采用台达PLC控制步进电机驱动丝杠运动,从而实现对发动机转速的控制,并可通过触摸屏修改控制参数以进行现场调试,使得液力变矩叉车在怠速作业时通过操纵手柄就可以顺利、稳定地进行平移、提升或倾斜作业,让叉车操作更加方便,且降低了操作人员的劳动强度。
By researching the characteristics of hydraulic torque forklifts,we developed a device which achieved inching function. It can detect position of the handle,using Delta PLC controlled stepper motor driven screw movement,to achieve the control of the engine speed,and modify the control parameters via touch-screen on-site commissioning,to achieve a truck at idle operation,through the manipulation of the handle can smooth and stable pan,lift or tilt operation,making operation of forklift more convenient and reduce the operator＇s labor intensity,having a high value market applications.
