The invention belongs to the technical field of elevator equipment, and particularly relates to an inspection device capable of detecting personnel falling into a pit, which comprises an elevator shaft, a shaft bottom terrace mounted at the lower end of the elevator shaft, a cleaning mechanism arranged in the elevator shaft, and a plurality of mounting grooves formed in the upper surface of the shaft bottom terrace, microwave radars and infrared sensors staggered with the microwave radars are mounted on the lower walls of the mounting grooves correspondingly, transparent glass is inserted into openings of the mounting grooves correspondingly, the upper surfaces of the transparent glass are cleaned through a cleaning mechanism, the cleaning mechanism comprises a cleaning brush horizontally arranged in the elevator shaft, and electric sliding rails are horizontally mounted on the two sides of the elevator shaft correspondingly; the upper surfaces of the two electric sliding rails are connected to the two ends of the cleaning brush correspondingly, and foam plates are embedded in the lower surfaces of the two sliding blocks correspondingly. Two types of sensors can be combined for judgment, so that whether a person falls down or not can be accurately judged, and meanwhile, the device is not limited by conditions such as a dim hoistway.
本发明属于电梯设备技术领域,具体涉及一种能检测人员坠落底坑的检查装置,包括电梯井,电梯井的下端安装有井底地坪,电梯井的内部设置有清洁机构,井底地坪的上表面开设有多个安装槽,安装槽的下壁均安装有微波雷达以及与微波雷达错开的红外传感器,安装槽的开口处均插设有透明玻璃,透明玻璃的上表面通过清洁机构进行清洁,清洁机构包括水平设置在电梯井内部的清洁刷,电梯井的两侧均水平安装有电动滑轨,两个电动滑轨的上表面分别连接于清洁刷的两端,两个滑块下表面均嵌入安装有泡沫板。本发明能够利用两类传感器结合判断,从而准确判断出坠落的是人员,同时不受到井道昏暗等条件限制。
