我矿有自卸汽车50台(T20、BJ371、BJ374),近三年来,运行中多次出现车厢自行升起拉断高压电线,造成停电、停产,经济损失达10万元以上。造成事故的原因是,汽车在运行中或卸矿之后,车厢是否按时落位、运行中车厢是否自动上升,司机都不知道。为解决这一问题,在车上增加一个起斗报警装置。该装置的作用是,车厢离开大梁升起,装在驾驶室操作盘上的红色信号灯,因电源接通而发亮(无论是正常卸矿或非正常的自动起斗都会发亮),当车厢完全落位,则因电源断开,信号自动熄灭。 I mine 50 dump trucks (T20, BJ371, BJ374). In the recent three years, many times in operation, the cabins themselves rise and pull off high voltage electric lines, resulting in power failure and production stoppage. The economic losses have reached over 100,000 yuan. The cause of the accident is whether the car is on time or not after the car is operating or unloading the mine, and whether the car is automatically raised during operation. The driver does not know. In order to solve this problem, a warning device for raising the cockpit is added to the car. The function of this device is that the compartment is lifted off the girder and the red signal light installed on the operation panel of the cab illuminates (whether it is normal unloading or abnormal self-lifting) Completely drop, then because the power is off, the signal automatically goes out.
