The invention discloses a boom telescopic control system and high-altitude operation equipment, the boom telescopic control system comprises a boom device, an in-place detection assembly and a trigger assembly, the boom device comprises a basic boom and a telescopic boom telescopically mounted in the basic boom; the in-place detection assembly comprises a first in-place detector and a second in-place detector which are close to a telescopic opening of the basic arm and installed on the basic arm, the trigger assembly comprises a retraction trigger piece and an extension trigger piece, and the retraction trigger piece is close to the outer end of the telescopic arm, installed on the telescopic arm and used for triggering the first in-place detector and the second in-place detector. The inner end, close to the telescopic arm, of the stretching triggering piece is installed on the telescopic arm and used for independently triggering the first in-place detector. According to the arm frame stretching control system, detection of whether the arm frame device is close to the retraction/stretching limiting position or not is achieved only through the two limiting switches; the control effect is obviously improved, the structure is simplified, the cost is reduced, and fault points are reduced.

    本发明公开一种臂架伸缩控制系统及高空作业设备,臂架伸缩控制系统包括臂架装置、到位检测组件和触发组件,臂架装置包括基本臂以及可伸缩地安装于基本臂内的伸缩臂,到位检测组件包括靠近基本臂的伸缩口安装于基本臂上的第一到位检测器和第二到位检测器,触发组件包括缩回触发件和伸出触发件,缩回触发件靠近伸缩臂的外端安装于伸缩臂上并用于分别触发第一到位检测器和第二到位检测器,伸出触发件靠近伸缩臂的内端安装于伸缩臂上并用于单独触发第一到位检测器,本发明的臂架伸缩控制系统仅使用两个限位开关就实现了臂架装置是否接近缩回/伸出极限位置的检测,则相较于现有技术,明显提升了操控效果、简化了结构、降低了成本以及减少了故障点。
