【技术实现步骤摘要】
绞盘开关
本技术涉及一种用于绞盘电机控制的绞盘开关。
技术介绍
现有技术的牵引绞盘,一般通过直流电机进行驱动,但要停止绞盘转动时,往往只是通过停止直流电机的供电来实现,但这并不能实现牵引绞盘的快速制动,从而影响牵引绞盘的使用安全性。
技术实现思路
本技术所要解决的技术问题是提供一种可控制绞盘电机的快速制动,提高绞盘使用安全性的绞盘开关。本技术是通过如下技术方案来实施的:绞盘开关,包括开关壳体和在开关壳体顶部设置的左右按钮,其特征在于:开关壳体内设有左右导柱和动静触片,左右导柱上下活动设置,左导柱的上下活动由左按钮进行按动由左复位弹簧进行复位,左导柱连接左动触片,右导柱的上下活动由右按钮进行按动由右复位弹簧进行复位,右导柱连接右动触片,静触片包括上中央触片、下中央触片、左触片和右触片,上中央触片连接接通直流正极电源的第一接线柱,上中央触片的左侧设有第一触点,右侧设有第二触点,下中央触片连接接通直流负极电源的第二接线柱,下中央触片的左侧设有第三触点,右侧设有第四触点,左触片连接接通直流电机负极端的第三接线柱,左触片的上下设有第五触点和第六触点,右触片连接接通直流电机正极端 ...
