Major function and operating principle
1. major function
1.1 air door is crashproof
The characteristics of splitting mutually when opening without the pressure balanced self closing door, track in each air door both sides is respectively equipped with car arrester 7, with air door 10 interlocks, when mine car excessive velocities and air door 10 not when opening fully, car arrester 7 will be at blocking state, thereby block mine car, avoid causing the damage of air door 10; After only having air door 10 to open fully, car arrester 7 just can be opened, and allows mine car pass through, thereby has protected air door 10, has ensured ventilation safety.
1.2 automatic illuminating
After air door 3 is opened, work between the twice air door for making things convenient for the workman, guarantee vehicle and the pedestrian safety by air door 3 time, set up automatic lighting lamp 8.
1.3 emergent release
Realize twice air door 10 interlocking, also be provided with two unlocking switches, in case of emergency, when having the people to press the magnetic switch of unlocking or host switch, main frame 3 outages, total system quits work, and can push air door open by manpower.This function mainly is to use when in particular cases twice air door 10 need to be opened simultaneously.After pressing the unlocking button, recover automatic control and must press first main frame button Shutdown Hosts 3, and then again start shooting by the main frame button.Voice prompt alarm when air door 10 is opened.
1.4 remote measurement and control
For closing of remote monitoring and emergent control air door 10, we have increased corresponding module, have realized the function that Long-distance Control under the monitoring of air door state and the emergency rating is closed.
1.5 voice light warning
The voice sound and light of alarm is arranged, the A door when opening the door: " air door is opened, and please notes safety ", simultaneously B door alarm: " the place ahead air door is opened, and Please Wait ".Through suitable memory time-delay, this device self-closing damper 10 guarantees automatically to be in closed condition pedestrian and vehicle convenience by rear air door 10 after pedestrian or vehicle pass through.After air door 10 shut, alarm voice and red light were closed, green light Chang Liang.
2. operating principle
2.1 the realization of close-distance safety control
Be provided with monitoring at air door 10 and open and close sensor 5, locking cylinder 4, illuminating lamp 8, phonetic alarm 6, be respectively equipped with car arrester 7 on the track 9 of each air door both sides simultaneously.Starting drive, monitoring switching sensor 5, locking cylinder 4, illuminating lamp 8, phonetic alarm 6, car arrester 7 all are connected with central controller, and central controller interlocks control to air door 10.
Central controller adopts infrared ray sensor 1 as medium, form respectively a sightless pilot wire at the two ends of mine laneway air door 10, when pedestrian or vehicle enter the A door by the either direction in tunnel, the infrared switch sensor automatically detects and provides signal for control appliance, signal is input to programmable logic controller PLC process after, pneumatic control case 2 control cylinders are opened the A air door automatically, simultaneously B door locking.On the door intrinsic safety type position sensor is housed, that detects air door closes, closes state.The voice sound and light of alarm is arranged, the A door when opening the door: " air door is opened, and please notes safety ", simultaneously B door alarm: " the place ahead air door is opened, and Please Wait ".Through suitable memory time-delay, this device self-closing damper guarantees automatically to be in closed condition pedestrian and vehicle convenience by rear air door after pedestrian or vehicle pass through.After air door shut, alarm voice and red light were closed, green light Chang Liang.
The controlled car arrester that track in each air door both sides is respectively equipped with, state at ordinary times is blocking state, and after air door was opened fully, programmable logic controller PLC sent instruction, opens valve, and the cylinder-pushed connecting rod is opened controlled car arrester.
In after air door is opened, the lighting between the air door of both sides is opened.
2.2 the realization of remote measurement and control
The air door twice all have air door to open and close sensor, and the air door open and-shut mode is transferred to ground by monitoring system, also the opening angle of air door is monitored simultaneously, opening angle is converted to the signal of 200-1000Hz by encoder, data processing and freq converting circuit, import monitoring system into and be transferred to ground.
The control of air door is to send instruction by monitoring system, triggers the air door automatic controller by this locality control output of substation or the far-end control contact of outage actuator, realizes the function that Long-distance Control is closed.
