The invention discloses a vertical telescopic arm. The vertical telescopic arm comprises a telescopic arm assembly, a lifting oil cylinder and a synchronous retraction assembly, wherein the telescopic arm assembly comprises a plurality of sections of telescopic pipes which are sequentially connected in a sleeved manner, and the telescopic pipes can axially slide in a telescopic manner; the lifting oil cylinder is installed on the telescopic arm assembly and directly drives one telescopic pipe to stretch out and draw back; the synchronous retraction assembly is installed on the telescopic arm assembly and is in linkage with the multiple telescopic pipes, and all the telescopic pipes are driven to retract synchronously under linkage of the synchronous retraction assembly; and a plurality of observation windows are formed in the telescopic arm assembly. The abrasion condition of the synchronous retraction assembly can be conveniently observed through the observation windows formed in the telescopic arm assembly, the synchronous retraction assembly can be conveniently replaced under the condition that the telescopic arm assembly is not disassembled, the use safety performance of a product is improved, the maintenance cost is greatly reduced, maintenance is convenient, and the overhaul time is shortened.

    本发明公开了一种垂直伸缩臂,包括:伸缩臂组件、举升油缸、同步缩回组件,伸缩臂组件包括若干节依次套接的伸缩管,伸缩管之间可轴向伸缩滑动;举升油缸安装在伸缩臂组件上并直接驱动其中一节伸缩管伸缩;同步缩回组件安装在伸缩臂组件上并联动若干节伸缩管,在同步缩回组件的联动下带动所有的伸缩管同步缩回;伸缩臂组件上开设有多个观察窗,通过在伸缩臂组件上开设的观察窗,能方便的观察同步缩回组件的磨损情况和在不拆卸伸缩臂组件的情况下更换同步缩回组件,提高了产品使用安全性能,大大降低维护成本,维护方便,缩短了检修时间。
