随着起重机市场的日益发展,新型结构的起重机产品不断出现,适宜在大型车间内使用的旋转伸缩式起重机就就是1种新结构起重机。本文介绍其吊臂加工工艺。1.组成及主要结构件(1)组成旋转伸缩式起重机吊臂由旋转臂、旋转驱动装置、伸缩臂、伸缩驱动装置、电动葫芦轨道等组成,如图1所示。旋转臂可在旋转驱动装置的驱动下做水平方向回转动作,伸缩臂可以在伸缩驱动装置的驱动下在旋转臂上伸缩,电动葫芦轨道安装在伸缩臂下端,用于承载电动葫芦及所吊货物的质量。
As crane markets continue to evolve, new types of crane products are emerging, and rotary telescopic cranes suitable for use in large plants are a new type of crane. This article describes its boom processing technology. 1. Composition and main structural parts (1) Rotary telescopic crane boom composed of rotating arm, rotary drive, telescopic boom, telescopic drive, electric hoist orbital and other components, shown in Figure 1. The rotary arm can be rotated horizontally by the rotary driving device. The telescopic arm can be telescopically driven by the telescopic driving device on the rotary arm. The electric hoist rail is installed at the lower end of the telescopic arm for carrying the electric hoist and the goods being hoisted the quality of.
