[0022] Reference Figure 1 , Figure 2 and Figure 3 When the scraper chain breaks, the power will be cut off through the protection device, which is convenient for handling faults. However, when the chain breaks, the broken chain is easy to be thrown out or displaced, which poses a great safety hazard, and the later repair and reset is time-consuming and labor-intensive. The hydraulic rod 301 and the scraper 2 are connected by a flange, and the connecting line 302 and the hydraulic rod 301 and the control valve 303 are all connected by threaded tightening. The control line 105 and the second data interface 304 are connected by threaded tightening. When the chain 4 on the scraper 2 breaks, the PLC controller 106 can control multiple groups of control valves 303 to start after receiving the signal, and intercept the chain 4 and the scraper 5 by rising the hydraulic rod 301. When used in conjunction with the chain break protector 102, the driving wheel of the scraper 2 stops running while the chain 4 can be stabilized, reducing the risk of the chain 4 being thrown out at the break and improving the overall safety.

[0023] Reference Figure 1 and Figure 2The chassis 101 and the scraper 2 are connected by bolts, the chain break protector 102 and the chassis 101 are connected by bolts, the chain break protector 102 and the PLC controller 106 are electrically connected, the PLC controller 106 and the warning light 103 and the control line 105 are electrically connected, the chain break protector 102 and the driven wheel set at one end of the scraper 2 are connected by a coupling, the PLC controller 106 is connected to the motor controller on the driving wheel set at one end of the scraper 2 through the first data interface 104, and the scraper When the trigger 2 is working normally, its driven wheel rotates with the driving wheel, and the driven wheel maintains a certain speed. When faults such as chain breakage, belt breakage, and slippage occur, the speed of the driven wheel drops significantly or even becomes zero. The chain break protector 102 monitors the speed of the driven wheel. When the speed of the driven wheel is lower than the set value, the abnormal signal of the chain break protector 102 is transmitted to the chassis 101, and the chassis 101 outputs a switch signal to control the motor controller on the driving wheel to stop running, thereby protecting the entire equipment, and issuing an audible and visual warning through the warning light 103 to prompt the operator to handle the fault.

[0024] Working principle: The hydraulic rod 301 of the chain-breaking protection device of the scraper chain is connected to the scraper 2 through a flange, the connecting line 302 and the hydraulic rod 301 and the control valve 303 are all screwed together through threads, and the control line 105 and the second data interface 304 are screwed together through threads. When the chain 4 on the scraper 2 is broken, the PLC controller 106 receives the signal and can control multiple groups of control valves 303 to start, and the hydraulic rod 301 rises to intercept the chain 4 and the scraper 5. When used in conjunction with the chain-breaking protector 102, the driving wheel of the scraper 2 stops running, and the chain 4 can be stabilized, reducing the risk of the chain 4 being thrown out at the break, thereby improving the overall safety. The chassis 101 and the scraper 2 are connected by bolts, the chain-breaking protector 102 and the chassis 101 are connected by bolts, and the chain-breaking protector 102 and the PLC controller 106 are connected by electricity.

The PLC controller 106 is connected to the motor controller on the driving wheel arranged at one end inside the scraper 2 through the first data interface 104. When the scraper 2 works normally, its driven wheel rotates with the driving wheel, and the driven wheel maintains a certain speed. When faults such as chain breakage, belt breakage, and slippage occur, the speed of the driven wheel drops significantly or even becomes zero. The chain break protector 102 monitors the speed of the driven wheel. When the speed of the driven wheel is lower than the set value, the abnormal signal of the chain break protector 102 is transmitted to the chassis 101, and the chassis 101 outputs a switch signal to control the motor controller on the driving wheel to stop running, thereby protecting the entire equipment, and sends out an audible and visual warning through the warning light 103 to prompt the operator to handle the fault.
