目前在现有领域的绞盘中,绞盘减速器上的离合常见是采用手动离合方式。一般绞盘在野外救援的时候,遇到恶劣的环境,通常会使用无线遥控器去控制绞盘的收绳和放绳工作。这时,启动绞盘需要开启离合,目前市面上的绞盘基本采用的手动离合的方式去开启或者关闭离合,这表明在启用绞盘的时候,还需要去绞盘边上去手动操作离合,使用起来不是很方便。有了电动离合以后,可以通过无线遥控器去控制离合的开启或者闭合,然后继续给遥控器发送指令,控制绞盘的转动;在国外绞盘使用无线遥控器去控制已经十分普及,但是无线遥控器会存在同频率干扰问题,有时候会出现遥控器无法控制绞盘的状况,这时这款新型绞盘上还保留原来手动离合的机械结构,可以用手动离合去控制绞盘的开启或者关闭;绞盘的收绳的过程一般比较缓慢,有时情况比较紧急需要快速收绳离开使用环境。目前的绞盘都是采用一种速比进行工作,设计一款可以快速和慢速之间相互切换的绞盘可以说是对绞盘收放绳有很大的改进。At present, in the winches in the existing field, the clutch on the winch reducer is usually in the manual clutch mode. Generally, when the winch is in the field for rescue, if it encounters a harsh environment, a wireless remote control is usually used to control the winch's rope-in and rope-out work. At this time, the clutch needs to be turned on to start the winch. At present, the winches on the market basically use the manual clutch to turn on or off the clutch, which means that when the winch is turned on, it is necessary to go to the side of the winch to manually operate the clutch, which is not very convenient to use. . With the electric clutch, you can control the opening or closing of the clutch through the wireless remote control, and then continue to send instructions to the remote control to control the rotation of the winch; it is very popular to use the wireless remote control to control the winch abroad, but the wireless remote control will There is the same frequency interference problem, and sometimes the remote control cannot control the winch. At this time, this new winch still retains the original manual clutch mechanical structure, and the manual clutch can be used to control the opening or closing of the winch; The process is generally slow, and sometimes the situation is more urgent and it is necessary to quickly withdraw the rope and leave the use environment. Present winch all is to adopt a kind of speed ratio to work, and designing a winch that can switch between fast and slow speed can be said to have very big improvement to winch retracting and unwinding rope.
