The invention relates to the technical field of coal mine underground safety transportation, and discloses a coal mine monorail vehicle distance measurement alarm device. The device comprises a monorail crane cab, ultrasonic ranging devices are installed on the two sides outside the cab, a control console is arranged in the monorail crane cab, a central controller is arranged in the control console, an emergency stop device is arranged on the control console, and a normally-closed contact of the emergency stop device is connected with the central controller through a coil and an optical coupler. A display and an audible and visual alarm are also arranged on the control console; and the display and the audible and visual alarm are connected with the central controller through lines. The monorail hoist is improved, the distance between the cab and the mine tunnel wall is detected by installing the ultrasonic distance measuring device, when the distance exceeds a set value, an alarm is given, the hoist body is braked, and the problem that when the distance between the hoist body and the mine tunnel wall is too close, the mine tunnel wall is prone to being scratched by transported materials can be effectively solved; and the underground transportation safety is further improved.
本发明涉及煤矿井下安全运输技术领域,且公开了一种煤矿单轨车测距报警装置;所述装置包括单轨吊司机室,所述司机室外两侧装有超声波测距装置,所述单轨吊司机室内设置有控制台,所述控制台内设置有中央控制器,所述控制台上设置有急停装置,所述急停装置常闭触点通过线圈、光耦合器与所述中央控制器相连,所述控制台上还设置有显示器和声光报警器,所述显示器和声光报警器通过线路和所述中央控制器相连。本发明对单轨吊车进行了改进,通过安装超声波测距装置来检测司机室与矿道壁的距离,当距离超过设定值时进行报警并制动车体,能有效解决车体与矿道壁距离太近时易发生运输物料剐蹭矿道壁的问题,使井下运输安全性得到进一步的提升。
