1常用导绳器的结构和原理导绳器的作用是使钢丝绳自动规则缠绕,防止出现跳槽现象导致钢丝绳乱绳、变形、加速磨损等而降低安全性。导绳器另一作用就是自动上下限位,当电动葫芦上升或者下降到一定高度的时候,导绳器把电动葫芦卷筒上的拉杆顶进或者拉出,这样断火限位器就处于断电或通电状态,从而使葫芦自动停止或运行。因此导绳器的作用还是非常重要的。目前常用的是圆环式导绳器,如图1所示,由几段(3~5段)组成一个圆环,又称为螺母,套在卷筒外面,其本身不能转动,靠其与卷筒的螺纹副关系沿卷筒轴向移动。
The structure and principle of a common guide rope The guide rope role is to make the automatic winding wire rope to prevent the phenomenon of job-hopping wire rope rope, deformation, accelerated wear and tear and reduce safety. The other role of the guide rope is automatically up and down the limit, when the electric hoist rise or fall to a certain height, the guide rope hoist rod trolley jacking or pulled out, so the fire stopper is off Electricity or electricity, so that the hoist automatically stop or run. Therefore, the role of guide rope is still very important. Now commonly used is the circular guide rope, as shown in Figure 1, by a few paragraphs (3 to 5) to form a ring, also known as the nut, set outside the reel, which itself can not be rotated, by its The thread relationship of the spool moves in the axial direction of the spool.
