AI Technical Summary
Technical Problem
Existing molten iron transport railcars lack derailment monitoring and alarm devices, resulting in a lack of operational safety and the risk of a series of accidents caused by derailment.
Method used
A laser rangefinder and an inclination sensor are installed on the running gear of the rail vehicle. The derailment situation is determined through the signal processing module, and an emergency stop command is sent.
Benefits of technology
It enables the self-propelled rail vehicle to take emergency stopping measures immediately when it derails, reducing the damage to the vehicle caused by the derailment.

Abstract
The invention discloses a derailment alarm device for a self-propelled rail car. The derailment alarm device comprises a self-propelled rail car walking part and a derailment alarm device body. The self-propelled rail car walking part comprises a swing bolster, a wheel pair and a side frame; the two ends of the swing bolster are each provided with a side frame, the portions, on the inner sides of the side frames, of the swing bolster are each provided with a wheel pair, and the wheel pairs drive the self-propelled rail car to move through rolling friction between the wheel pairs and a steel rail. The derailment alarm device comprises a laser range finder, a tilt angle sensor and a signal processing module; the laser range finder is installed on the side face of the swing bolster and used for measuring the distance between the swing bolster and a steel rail. The tilt angle sensor is installed on the bottom face of the swing bolster and used for measuring the included angle of the swing bolster relative to the ground. The signal processing module is in communication connection with the laser range finder and the tilt angle sensor and used for judging whether the current self-propelled rail car has the derailment risk or not according to data transmitted by the laser range finder and the tilt angle sensor. According to the invention, the derailment abnormal information can be sent to the control system at the first time, so that the self-propelled rail car can make corresponding actions such as sudden stop and unloading, and greater damage to the self-propelled rail car caused by derailment is reduced.
