The invention relates to a warning device for preventing falling objects in an overhead working truck from hurting people. The warning device comprises a working bucket of the overhead working truck, a plurality of laser distance measuring sensors with downward detection heads are arranged on the outer bottom face of the working bucket, a plurality of laser projectors with downward projection heads are arranged on the periphery of the working bucket, an audible and visual alarm is further arranged on the working bucket, and the laser distance measuring sensors, the laser projectors and the audible and visual alarm are electrically connected with a PLC. The device is mounted on the working bucket of the overhead working truck to realize a warning function, the laser distance measuring sensors, the laser projectors and the audible and visual alarm are mainly used for preventing ground personnel from entering a dangerous area below the working bucket of the overhead working truck, if the ground personnel enter the dangerous area, the alarm can give an audible and visual alarm, and the potential risk that the falling objects in the overhead working truck hurt people is avoided.
本发明涉及一种高空作业车防坠落物伤人警示装置,包括高空作业车的作业斗,作业斗的外底面设置有若干个检测头朝下的激光测距传感器,作业斗的外周部设置有若干个投射头朝下的激光投射器,作业斗上还设置有声光报警器,激光测距传感器与激光投射器、声光报警器均与PLC控制器电性连接。本装置安装于高空作业车作业斗实现警示功能。主要通过激光测距传感器、激光投射器、声光报警器实现防止地面人员进入到高空作业车作业斗以下危险区域内,如果地面人员进入了危险区域,报警器将会发出声光报警,避免高空作业车落物伤人的潜在风险。
