At present, domestic outer portion mine hoist, particularly large-scale multi-rope friction hoisting machine majority uses working-point
Permanent deceleration safety braking system realizes safety arrestment process.Double-working-point constant speed reduction safety braking system is according to mine hoist
Safety arrestment requirement and lifting system need to preset two operating points, electricity of the main electric-control system in the lifting course of work
Stream characteristic parameter identification lifting system weight is above carried or weight decentralization operating mode, in safety arrestment under heavy duty above puies forward operating mode, closed loop
System is automatic to carry out constant deceleration brake according to larger deceleration operating point；Safe system is carried out under heavy-load lowering operating mode when changing into
When dynamic, closed-loop system is then automatic to carry out constant deceleration brake according to less deceleration operating point.
Above-mentioned mode of braking improves braking stationarity and security reliability, with good from double setting operating points
Braking ability, but because the operating point that its permanent deceleration closed loop gives is two operating points pre-setting, pass through operating mode difference choosing
Operating point setting value is selected to have the following disadvantages：
1st, the Closed loop operation point of this closed-loop control system has two advance setting values.In most cases, lifted
Mass of system modulus (lifting system effectively lifts load and net slip mass ratio value) is smaller, and multirope friction winder heavy duty is carried
Minimum braking subtracts as defined in safety code when minimum anti-skidding limit braking deceleration is more than lifting system heavy-load lowering when rising operating mode
Velocity amplitude.And in actual lifting system, if lifting system quality modulus is larger, it is possible to minimum anti-skidding limit braking occur
Minimum braking deceleration angle value is close as defined in safety code when deceleration value is with lifting system heavy-load lowering, be even less than the latter's
Situation.In this case, larger deceleration operating point is assigned to weight by closed loop brake system automatically according to the size of setting value
Operating mode is put forward in load, less deceleration operating point is assigned to heavy-load lowering operating mode, it is impossible to the safe operation bar of elevator is met
Part.
2nd, using the operating point of pre-set deceleration, it is impossible to meet the safety when elevator Parameters variation
Braking, it is impossible to reach and allow the purpose of elevator emergency within the shortest time.
The content of the invention

Characteristic that the sensors such as deceleration intelligence computation module is according to weighing, position, speed are measured and elevator
There is related parameter, with reference to《Safety regulations in coal mine》, the maximum deceleration value of elevator permission is calculated in real time；Brake control module
Control instruction, control instruction warp are sent after the signal value of given deceleration value and detection feedback device actual feedback is compared
Cross after the modes such as amplification, correction handle, 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) annunciator panel shape brake 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 motion state of the braking moment control lifting system of formation is according to input control instruction changing rule
And change (braking deceleration), the control to lifting system is implemented, the safety arrestment of mine hoist is realized.
Due to using technical scheme as described above, the present invention has following superiority：
1st, in the larger situation of lifting system quality modulus (lifting system effectively lifts load and net slip mass ratio)
Under, it is possible to it is minimum as defined in safety code when there is minimum anti-skidding limit braking deceleration value with lifting system heavy-load lowering to make
Dynamic deceleration value is approached, even less than the latter.In the present invention, closed loop brake system according to setting value size, 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 can just realize the number of lifting system quality modulus
How value changes, and the permanent deceleration safety arrestment effect of constant closed loop can be realized under various more extreme lifting 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 may occur
Change, such as lift skip bucket abrasion, charging ratio change, discharging is clean etc. will all influence the size of quality modulus, and then influence
The setting of deceleration operating point.In the present invention, technical scheme can pass through deceleration intelligence according to various sensor measured datas
