Permanent deceleration safety braking system is realizing safety arrestment process.Double-working-point constant speed reduction safety braking system is according to mine hoist
Safety arrestment requirement and lift system need to preset two operating points, and main electric-control system is according to the electricity in lifting work process
Stream characteristic parameter identification lift system weight above carries or weight decentralization operating mode, when heavy duty above proposes safety arrestment under operating mode, closed loop
System carries out constant deceleration brake according to larger deceleration operating point automatically；Carry out safe system when changing under heavy-load lowering operating mode
When dynamic, closed loop system then carries out constant deceleration brake according to less deceleration operating point automatically.
Above-mentioned mode of braking sets operating point from double, improves braking stationarity and security reliability, has good
Braking ability, but because the operating point that its permanent deceleration closed loop gives is two operating points pre-setting, by the different choosing of operating mode
Select operating point setting value to have the following disadvantages:
1st, the Closed loop operation point of this closed-loop control system has two setting values in advance.In most of the cases, lifted
Mass of system modulus (lift system effectively lifts load and net slip mass ratio value) is less, and multirope friction winder heavy duty carries
The minimum braking rising safety codes regulation when minimum anti-skidding limit braking deceleration is more than lift system heavy-load lowering during operating mode subtracts
Velocity amplitude.And in actual lift system, if lift system quality modulus is larger braked it is possible to the minimum anti-skidding limit occurs
When deceleration value and lift system heavy-load lowering, the minimum braking deceleration angle value of safety codes regulation is close, be even less than the latter's
Situation.In this case, closed loop brake system, according to the size of setting value, is assigned to weight larger deceleration operating point automatically
Operating mode is carried on load, less deceleration operating point is assigned to heavy-load lowering operating mode it is impossible to meet the safe operation bar of elevator
Part.
2nd, using pre-set deceleration operating point it is impossible to meet the safety when elevator Parameters variation
Braking it is impossible to reach allows the purpose of elevator emergency within the shortest time.
Content of the invention
In order to shorten the safety arrestment time, the range ability of hoisting container when reducing safety arrestment, the present invention will solve
Technical problem be provide a kind of mine hoist Intelligent safe brakes, make the system of mine hoist sure brake system
Dynamic performance and range of application increase, and lay the foundation for improving mine hoisting system tractor parameter performance simultaneously.

The sensors such as degree, acceleration, the signal that sensor-based system detects sensor is sent to deceleration after removing process of making an uproar after filtering
Intelligence computation module.
Characteristic that the sensors such as deceleration intelligence computation module is according to weighing, position, speed record and elevator
There is related parameter, in conjunction with " safety regulations in coal mine ", calculate the maximum deceleration value of elevator permission in real time；Brake control module
Control instruction, control instruction warp is sent after the signal value of given deceleration value and detection feedback device actual feedback is compared
After the modes such as amplification, rectification of crossing are processed, hydraulic pressure signal is converted to by electro-hydraulic proportion reversing valve, electro-hydraulic proportion reversing valve output is pressed
The normal pressure of hydraulic pressure (flow) the annunciator panel shape brake oil cylinder piston rod output of input instruction change, disc braking
Remaining normal pressure after the normal pressure of device cylinder piston rod output is offset with disc-brake spring force is acted on by brake shoe
In brake disc (brake disc), the braking moment of formation controls the kinestate of lift system according to input control instruction Changing Pattern
And change (braking deceleration), implement the control to lift system it is achieved that the safety arrestment of mine hoist.
Due to using technical scheme as above, the present invention has a following superiority:
1st, in the situation that lift system quality modulus (lift system effectively lifts load and net slip mass ratio) is larger
Down it is possible to the minimum system that the minimum anti-skidding limit brakes deceleration value and safety codes regulation during lift system heavy-load lowering occurs
Dynamic deceleration value is close, even less than the latter.In the present invention, closed loop brake system according to the size of setting value, automatically larger
Deceleration operating point be assigned to heavy duty and above put forward operating mode, less deceleration operating point is assigned to heavy-load lowering operating mode can not expire
The safe operating conditions of sufficient elevator.So, no matter technical solution of the present invention just can realize the number of lift system quality modulus
How value changes, and all can realize constant closed loop perseverance deceleration safety arrestment effect under various more extreme lift system parameters.
2nd, in mine hoisting system work, safety arrestment, Ke Nengyu are carried out according to deceleration operating point set in advance
There is very big difference in elevator actual condition, do not reach preferable on-position because the various parameters of elevator it may happen that
Change, the such as abrasion of lifting skip bucket, charging ratio change, discharging unclean etc. all will impact quality modulus size, and then affect
The setting of deceleration operating point.In the present invention, technical scheme can be according to various sensor measured datas, by deceleration intelligence
