电动葫芦是什么？
What is an electric hoist?
电动葫芦是一种特起重设备，安装在天车、龙门吊之上。电动葫芦具有体积小，自重轻，操作简单，使用方便等特点，用于工矿企业，仓储，码头等场所，同时也安装在单梁起重机，桥式起重机，门式起重机，悬挂起重机上。稍加改造，还可以作卷扬机用。钢制闸门 钢坝 保定轻钢别墅 保定平面设计培训 保定室内设计培训 保定办公家具 保定空调维修
Electric hoist is a special lifting equipment, which is installed on crown block and gantry crane. Electric hoist has the characteristics of small volume, light weight, simple operation and convenient use. It is used in industrial and mining enterprises, storage, wharf and other places. At the same time, it is also installed on single beam crane, bridge crane, gantry crane and suspension crane. With a little modification, it can also be used as a winch.
电动葫芦结构紧凑，电机轴线垂直于卷筒轴线的电动葫芦采用蜗轮传动装置。其缺点为：长度尺寸大，宽度方面尺寸大，结构粗笨，机械效率低，加工较难等。液压系统为双重控制，溢流调节阀、磁接点压力表均可对压力进行精确的控制。电器控制部门采用了低电压控制，增加了支配系统的安全性。
The electric hoist has compact structure, and the motor axis is perpendicular to the drum axis. The electric hoist adopts worm gear transmission device. Its disadvantages are: large length, large width, bulky structure, low mechanical efficiency, difficult processing, etc. The hydraulic system is dual control, and the overflow regulating valve and magnetic contact pressure gauge can accurately control the pressure. The electrical control department adopts low voltage control, which increases the safety of the control system.
电动葫芦分为超高起重电动葫芦、地铁用电动葫芦、高起升速度电动葫芦、固定式电动葫芦、水平出绳丝电动葫芦、环形轨道电动葫芦。
The electric hoist is divided into ultra-high lifting electric hoist, subway electric hoist, high lifting speed electric hoist, fixed electric hoist, horizontal wire outlet electric hoist and circular track electric hoist.
