本文主要是针对电动葫芦在使用中出现的安全问题进行分析,指出设计中仅采用单一的上升限位保护所带来的缺陷,采用在电动葫芦上加装无触头接近开关,控制回路中加串常闭触头双重上升限位保护的措施,以确保运行的安全。
This paper mainly analyzes the safety problems appearing in the use of electric hoist, points out that the design only uses the single rising limit protection to bring the defect, uses in the electric hoist to install the contactless proximity switch, the control loop Canada Series normally closed contact double limit protection measures to ensure the safety of the operation.
