[0002] In steel and mining enterprises, most raw materials, such as mineral powder, are transported by rail to designated locations, unloaded by self-dumping wagons onto underground conveyor belts, and then transported to the next processing stage. A train of self-dumping wagons consists of multiple wagons. When a train arrives at the unloading site, ground personnel direct the driver to align a particular wagon with the unloading port. Ground personnel then manually open the corresponding wagon's valve to unload the material. The large number of multi-wagon wagons increases the workload for both drivers and ground personnel, necessitating improvements. Summary of the Invention

[0025] Work process

[0026] When the three-way valve is switched to one side (manual side), the tilting air cylinder of the corresponding self-tipping car is inflated or deflated via the manual valve, causing the tilting air cylinder push rod to rise or fall. The manual side is usually used for tilting air cylinder maintenance. When the three-way valve is switched to the other side (automatic side), the tilting air cylinder of the corresponding self-tipping car is started / stopped via the corresponding "start / stop switch" on the remote control. The tilting air cylinder push rod is raised / lowered to drive the corresponding self-tipping car body to tilt / reverse. The driver observes the tilting angle of the car body through the touch screen. The driver also observes the position information of the position switch through the touch screen. When the position switch signal changes color (usually green), the corresponding self-tipping car body reaches the unloading port and stops.

[0027] This utility model features a position switch on each self-tipping car section, connected to a PLC. This allows the driver to accurately stop the corresponding car section at the unloading port by observing the position switch signal on the touchscreen. Each car section also has a tilt sensor, allowing the driver to monitor the tilt angle at any time via the touchscreen, eliminating the need for ground personnel to visually determine the unloading port position and assist the driver in unloading, thus reducing labor intensity. Each car section also has a three-way valve, allowing the tilting air cylinder to be vented via either an electronically controlled valve or a manual valve. If the tilting air cylinder malfunctions, ground personnel can manually vent / exhaust it via the manual valve for easy maintenance. The remote control includes a start / stop switch for the electronically controlled valve of each car section. The driver can operate the corresponding switch to open the solenoid valve of the corresponding car section, venting the tilting air cylinder and driving the car section to tilt / reverse. The design is simple and saves production costs.
