DDZ type broken belt catcher is mainly composed of six parts: monitor, controller of broken belt catcher, host of broken belt catcher, mining flameproof speed sensor, mining flameproof position sensor, catching mechanism and speed measuring support.
The speed sensor detects the running condition of the belt, the position sensor detects the status of the rotating arm of the broken belt catching device, and feeds back the information to the host computer. The host computer converts the information fed back by the sensor and its own communication status information into digital signals and transmits them to the controller for information processing to judge whether the belt conveyor is broken, whether the speed exceeds the set range (stall), and whether the rotating arm of the broken belt catching device is normal Whether the speed sensor of the broken belt catching device is normal and the host communication is normal; At the same time, these information will be transmitted to the monitoring machine through the remote interface. When the belt breaks or the speed exceeds the set range, the controller will send a belt breaking control command to the host. After receiving the belt breaking control command, the host will control the action of the belt breaking catching mechanism to arrest the stalled or sliding belt, and control the accident at the initial stage to prevent the accident from expanding. At the same time, the controller will cut off the power supply of the belt conveyor controller circuit and control the audible and visual alarm to give an audible and visual alarm, Prevent friction between belt conveyor driving roller and belt; When the rotating arm of the broken belt catching device is abnormal or the host communication is abnormal, the controller will give an audible and visual alarm to remind the maintenance personnel to handle it.
