The invention belongs to the field of aerial work platforms, and discloses a pothole protection switch limiting device and an aerial work platform which comprise a pothole plate, a middle transmission mechanism, a guide rod and a limiting switch. The middle transmission mechanism is used for driving the pothole plate to be unfolded or folded and comprises a pothole plate connecting end and a guide rod contact end, the pothole plate connecting end is in transmission connection with the pothole plate, the guide rod can ascend and descend along with a working platform of the aerial work platform, the guide rod is located above the guide rod contact end, and the lower end of the guide rod abuts against the guide rod contact end. The limiting switch is adjacent to the upper portion of the guide rod and can detect whether the pothole plate is completely opened or not according to the lifting motion of the guide rod. The pit hole protection switch limiting device and the aerial work platform are reliable in structure and low in failure rate, and the production efficiency in the operation process can be effectively guaranteed.
本发明属于高空作业平台领域,公开了一种坑洞保护开关限位装置及高空作业平台,该坑洞保护开关限位装置及高空作业平台包括坑洞板、中间传动机构、导杆以及限位开关,中间传动机构用于驱动坑洞板展开或回收并包括坑洞板连接端和导杆接触端,坑洞板连接端与坑洞板传动连接,导杆能够随高空作业平台的工作平台升降,导杆位于导杆接触端的上方且下端抵压在导杆接触端上,限位开关与导杆的上部相邻布置并能够根据导杆的升降运动检测坑洞板是否完全打开。本发明的坑洞保护开关限位装置及高空作业平台结构可靠,故障率低,能有效保证作业过程中的生产效率。
