The invention discloses an anti-extrusion device. The anti-extrusion device comprises a movable mechanism, fixed mechanisms and a position signal detection mechanism, wherein the movable mechanism comprises a collision rod and movable frames; the two ends of the collision rod are connected with the movable frames respectively; a plurality of elastic elements are arranged between the movable framesand the inner walls of the fixed mechanisms and surround the movable frames; rod sections at the two ends of the collision rod are hinged to the fixed mechanisms respectively; the rod sections can rotate around a public sphere center relative to the corresponding fixed mechanisms, so that the collision rod can respond to extrusion thrust exerted on an operator and freely rotate; after the extrusion thrust disappears, the collision rod is automatically recovered to an initial state under the action of the elastic elements; and the position signal detection mechanism is mounted to detect and transmit a movable position signal of the collision rod, so that a control unit can perform control operation based on the movable position signal. The invention further discloses a high-altitude operation machine. The anti-extrusion device can be triggered in all directions, has an automatic resetting function, and is low in cost and high in reliability.

    本发明公开一种防挤压装置,包括活动机构、固定机构和位置信号检测机构,所述活动机构包括碰撞杆和移动架,所述碰撞杆两端分别与一个移动架连接,所述移动架与固定机构内壁之间且围绕移动架设有多个弹性元件,所述碰撞杆两端杆段分别与一个固定机构铰接,杆段能够相对对应的固定机构绕公共球心转动,以能够使碰撞杆响应于操作者所受挤压推力而使碰撞杆自由转动,且在所受挤压推力消失后在弹性元件作用下自动恢复到初始状态;所述位置信号检测机构安装为能够检测并传输碰撞杆的移动位置信号,以使控制单元能够基于移动位置信号进行控制操作。本发明还公开一种高空作业机械。本发明防挤压装置能够全方位触发,具备自动复位功能,成本低、可靠性高。
