It should be noted that in actual use, velocity sensor and pressure sensor are also equipped with conveyer, can be to fortune
Coal machine running status does real-time monitoring, and the one-to-one emergency braking apparatus is numbered with auxiliary cylinder 8 in advance, works as generation
During conveyer 7 fracture defect of belt, it can timely know which specific emergency braking apparatus is activated.
Step 2: judging whether conveyer belt is broken：It is using the infrared detector real-time detection conveyer belt 7
No fracture, when there is the infrared remote receiver 11-2 in the emergency braking apparatus to receive infrared signal, illustrate conveyer belt 7
Fracture, cause infrared remote receiver 11-2 coordinate infrared transmitter 11-1 between it is accessible, the infrared detector connect, hold
Row step 3；When no infrared remote receiver 11-2 receives infrared signal, illustrate that conveyer belt 7 is unbroken, it is infrared with this
Separated between the infrared transmitter 11-1 that receiver 11-2 coordinates by conveyer belt 7, infrared detector access failure, circulation step
Rapid one；
Step 3: sound and light alarm and brake hard conveyer, process are as follows：
Step 301, sound and light alarm：Microcontroller in the emergency braking apparatus that conveyer belt 7 is broken is detected in step 2
Device 1-4 drives audible-visual annunciator 1-5 emergency alarms after receiving the signal of infrared remote receiver 11-2 transmission, prompts conveyer belt
7 fracture position, while microcontroller 1-4 sends failure report by wireless radio frequency circuit 1-7 to conveyer remote console
Alert signal；
Detect that microcontroller 1-4 receives infrared remote receiver 11-2 in the emergency braking apparatus that conveyer belt 7 is broken
Audible-visual annunciator 1-5 emergency alarms, and the emergency braking apparatus for conveyer belt 7 will be detected being broken are driven after the signal of transmission
Numbering shown by display screen 1-6, while microcontroller 1-4 by wireless radio frequency circuit 1-7 to conveyer remote control
Platform sends the numbering of the emergency braking apparatus while sending failure alarm signal.
It should be noted that detecting the fracture position of conveyer belt 7 by infrared detector, and obtain brake hard dress
The numbering with auxiliary cylinder 8 is put, on the one hand the microcontroller 1-4 in the emergency braking apparatus drives audible-visual annunciator 1-5 first
Time alarms, and on the other hand drives wireless radio frequency circuit 1-7 to send fault-signal to conveyer remote console；
The selection of step 302, emergency braking apparatus：Conveyer remote console by with the brake hard in step 301
Device is communicated, and the motor drive module 1-8 in the emergency braking apparatus in rate-determining steps 301 does not work；Conveyer simultaneously
Remote console locks and selects to remove the remaining emergency braking apparatus work of emergency braking apparatus in step 301；
Worked it should be noted that the purpose of the selection of emergency braking apparatus is the effective mechanical arm 13 of control, due to red
Infrared remote receiver 11-2 in external detector when infrared transmitter 11-1 signal is received, illustrate conveyer belt 7 this
Place position has been broken, then during the pressing conveyer belt 7 of control machinery arm 13, speed departs from auxiliary rolling to conveyer belt 7
Cylinder 8, the pressing conveyer belt 7 of mechanical arm 13 is meaningless, therefore, the driving brake hard dress of conveyer remote console selectivity
Put, make to detect that the mechanical arm 13 in the emergency braking apparatus of the fracture of conveyer belt 7 does not work, make not detect conveyer skin
Mechanical arm 13 in emergency braking apparatus with 7 fractures works, and energy-conservation is effective, and control is accurate.
Step 303, brake hard conveyer：Conveyer remote console and the emergency braking apparatus selected in step 302
Communication, rotate rotary shaft 13-4 by its microcontroller 1-4 motor drive modules 1-8, rotary shaft 13-4, which is rotated, to be driven
Coordinate by pressing device 13-1 and auxiliary cylinder 8, make conveyer belt 7 is locked to brake conveyer on auxiliary cylinder 8；Pass through it simultaneously
Microcontroller 1-4 controls the electronic locking auxiliary braking conveyer of pulley 6；In addition, sound and light alarm is driven by its microcontroller 1-4
Device 1-5 additional alarms；
After conveyer remote console receives fault-signal, control does not detect the brake hard that conveyer belt 7 is broken
Mechanical arm 13 in device works, and realizes brake hard conveyer, while does not detect the brake hard that conveyer belt 7 is broken
Wireless radio frequency circuit 1-7 gives connected microcontroller 1-4 signals, microcontroller 1-4 order audible-visual annunciators in device
1-5 additional alarms work, while display screen 1-6 shows the volume of the breaking part emergency braking apparatus of conveyer belt 7 and auxiliary cylinder 8
Number, therefore, whole display screen 1-6 shows unified content, and using effect is good.
In the present embodiment, the one side coordinated by pressing device 13-1 with auxiliary cylinder 8 is cambered surface.
Step 4: conveyer is braked：Conveyer remote console controls the master rotor of the conveyer to shut down, and realizes transporting coal
Mechanism is moved.
The present invention is in use, conveyer remote console controls the master rotor of the conveyer to shut down, due to conveyer skin
The transportation range of band 7 is remote, and master rotor shuts down delay length, it is impossible to fast and effectively realizes that conveyer is braked, therefore, using multiple urgent
Brake apparatus is used cooperatively, and realizes conveyer brake hard.It is described above, only it is presently preferred embodiments of the present invention, not to this
Invention imposes any restrictions, every any simple modification substantially made according to the technology of the present invention to above example, change and
