The invention relates to the technical field of telescopic boom detection equipment, in particular to a telescopic boom in-place detection device, a telescopic boom assembly and an operation machine. The telescopic boom in-place detection device comprises a first mounting seat, a second mounting seat, an ejector rod, a first elastic piece, a second elastic piece and an induction mechanism, the first mounting seat is arranged at one end of the second knuckle arm assembly; the second mounting seat is arranged at one end of the first knuckle arm assembly; the ejector rod is driven by the first knuckle arm assembly and the second knuckle arm assembly to move; the ejector rod is movably connected with the first mounting seat through a first elastic piece and movably connected with the second mounting seat through a second elastic piece; and the sensing mechanism is arranged on the second mounting seat. The telescopic boom retraction monitoring device is simple in structure, retraction monitoring of the telescopic boom can be completed only by arranging one sensing mechanism, no signal circuit needs to be arranged, whether the knuckle boom assembly retracts in place or not is judged only according to whether the sensing mechanism triggers signals or not, and lightweight and miniaturized design of the telescopic boom frame is facilitated.

    本发明涉及伸缩臂检测设备技术领域,尤其涉及一种伸缩臂架到位检测装置、伸缩臂架组件及作业机械。该伸缩臂架到位检测装置包括:第一安装座、第二安装座、顶杆、第一弹性件、第二弹性件和感应机构;第一安装座设置于第二节臂组件一端;第二安装座设置于第一节臂组件一端;顶杆由第一节臂组件和第二节臂组件带动移动;顶杆通过第一弹性件与第一安装座可移动地连接、通过第二弹性件与第二安装座可移动地连接;感应机构设于第二安装座上。本发明其结构简单,仅设置一个感应机构,即可完成伸缩臂的回缩监测,无需布置信号线路,仅根据感应机构是否触发信号,判断节臂组件是否缩回到位,有利于伸缩臂架的轻量化和小型化设计。
