The invention discloses an anti-extrusion device which comprises a detection rod, a detection sensor and two connecting parts used for being connected with an aerial work platform, each connecting part comprises at least one elastic connecting part, and the detection sensor is connected with a control system of the aerial work platform and used for measuring the displacement amount of the detection rod. The two ends of the detection rod are connected with the two connecting parts respectively. When the aerial work platform is extruded, an operator can bend to avoid and extrude the detection rod. The elastic connecting part moves after being stressed, the detection sensor measures the displacement, and if the displacement amount is too large, the aerial work platform is stopped. And the detection rod is supported by the connecting part, enough deformation can be generated by extrusion of an object with a certain mass, and the risk of false detection is reduced. In addition, the detection rod shifts through downward pressing, the requirement for space is low, and the detection rod is not prone to being clamped. And the reliability of the anti-extrusion device is ensured. The invention further provides the aerial work platform comprising the anti-extrusion device, and the aerial work platform has the advantages.
本发明公开了一种防挤压装置,包括检测杆、检测传感器和两个用以与高空作业平台相连的连接部,连接部包括至少一个弹性连接部,检测传感器与高空作业平台的控制系统相连、且用以测量检测杆的位移量,检测杆的两端分别与两个连接部相连。当高空作业平台发生挤压时,操作人员会俯身躲避,并挤压检测杆。弹性连接部受到压力作用后位移,检测传感器对位移进行测量,如果位移量过大则停止高空作业平台。检测杆由连接部支撑,需要一定质量的物体挤压才能产生足够的形变,降低了误检测的风险。另外,检测杆经下压发生位移,对空间要求较低,不易卡住。保证了防挤压装置的可靠性。本发明还提供了一种包括上述防挤压装置的高空作业平台,并具有上述优点。
