Given threshold, then judge that brake force is abnormal.For the detection of brake response time, most producers are all by embracing
Whether lock microswitch is acted to judge whether brake band-type brake or declutches, and then brake is moved down to band-type brake microswitch
Make the time difference between feedback signal as the braking response time, be also to pass through when carrying out type approval test to elevator brake
This method detects the braking response time of brake.But, due to the row between band-type brake jogging switches measurement probe and contact
Journey is very short, generally 0.3mm, and its detection error has then reached 0.1mm or so, the braking response time error that this method is measured
Larger, precision is relatively low, and the detected value of general braking response time is both less than actual value, and the once judgement to the braking response time
Error, detected value is less than threshold value, and actual value has exceeded threshold value, such as the braking response time of band-type brake microswitch actual feedback
It is 0.4s, brake is normal operating conditions, but its actually 0.6s of real braking response time, have been over national standard rule
Now there is failure in fixed 0.5s, actual upper brake, once there is the feedback of this wrong braking response time, very

In order that the Cleaning Principle and its feature of the present invention more easily understand, with reference to embodiment, enter one
Step illustrates the present invention.
Fig. 1 is the detection principle diagram of elevator brake braking response time detection device in the present invention, and detection means is by bullet
Spring plank, resistance strain gage, deformeter and binary channels electrographic recording instrument composition, it is contemplated that the precision of detection, resistance strain gage is selected
High-precision foil resistance foil gauge 13, deformeter selects high-precision dynamic strain indicator 14, and detection object is installed in permanent magnetism
Drum brake 2 on synchnorous gearless dragging machine 1, the concrete arrangement of detection means is as shown in Fig. 2 drum brake 2
Operation principle be：When drum brake 2 is powered, calutron 3 obtains electric generation electromagnetic force, and electromagnetic force drives push rod 4 to outward transport

Rotated under around fixed pin shaft 7, brake block 8 holds braked wheel 9 tightly, complete braking.GB 7588-2003《Elevator is manufactured with installing
Safety standard》Regulation：It is all to participate in the brake mechanical part that braked wheel or disk apply brake force two assemblings being divided to set, electromagnetism
The iron core of coil is considered as mechanical part, and coil is not then, being arranged on permanent-magnet synchnorous gearless dragging machine 1 shown in Fig. 2
Drum brake 2 exactly provide that its mechanical part be divided to or so two to assemble to set according to this.
With reference to Fig. 2, the general principle to the detection means of elevator brake braking response time in the present invention is illustrated：
When 2 power-off brake of drum brake, tripping spring 5 starts to reply, and the decrement of tripping spring 5 is gradually reduced, then brakes bullet
The pressure that spring 5 is acted on the latch plate 11 of its end is gradually reduced, and the strain of latch plate 11 is also gradually reduced, accordingly, cloth
Put elongation reduction, cross-sectional area increase, foil resistance of the foil resistance foil gauge 12 on latch plate 11 in length direction
The resistance of foil gauge 12 is gradually reduced, then detects the output current signal of the dynamic strain indicator 14 of the strain of foil resistance foil gauge 12
Amplitude gradually increases, and when drum brake 2 reaches that specified braking moment completes braking, the length of tripping spring 5 no longer changes,
The pressure now acted on latch plate 11 is minimum, then the strain of latch plate 11 also reaches minimum, accordingly, is arranged in spring
The strain of foil resistance foil gauge 12 on plate 11 is minimum, and foil resistance foil gauge 12 is minimum, horizontal in the elongation of length direction
Sectional area is maximum, and the resistance of foil resistance foil gauge 12 reaches minimum, then detects that the dynamic of the strain of foil resistance foil gauge 12 should
The output current signal amplitude for becoming instrument 14 reaches maximum, is reached most from the power-cut time of drum brake 2 to the decrement of tripping spring 5
Time difference between the small moment is exactly the braking response time of drum brake 2, and this time difference is equal to disconnected from drum brake 2
The electric moment reaches the time difference between the maximum moment to the output current signal amplitude of dynamic strain indicator 14, and this time difference is then
Intuitively it can be obtained by the observation of binary channels electrographic recording instrument 15.
During using the detection means of elevator brake braking response time in the present invention to the braking response of drum brake 2
Between detected, comprise the following steps that：
(1) foil resistance foil gauge 12 is arranged on latch plate 11, then latch plate 11 is placed on tripping spring 5 one
End, because the addition of latch plate 11, increases the decrement of tripping spring 5, in order to not change the spring force of tripping spring 5, needs
The packing ring 13 and nut 16 in the outside of tripping spring 5 are adjusted, the decrement of tripping spring 5 is adjusted to and added latch plate
It is identical before 11；
(2) the output current signal end of drum brake 2 and dynamic strain indicator 14 is respectively connected to binary channels electrographic recording instrument
15 two signal input ports；
(3) due to the pressure of tripping spring 5, latch plate 11, which is pressurized, produces strain, and the strain is by foil resistance foil gauge 12
Detection, the strain of foil resistance foil gauge 12 then detects that the output signal of dynamic strain indicator 14 is electricity by dynamic strain indicator 14
Signal is flowed, when the strain of latch plate 11 changes, corresponding change, foil also occur for the strain of foil resistance foil gauge 12
Therefore the resistance of resistance strain gage 12 also changes, then corresponding change also occurs for the output current signal of dynamic strain indicator 14
Change, such as, when the pressure that tripping spring 5 is applied on latch plate 11 reduces, the strain of latch plate 11 reduces, foil resistance strain
The elongation of piece 12 reduces, and its length reduces, cross-sectional area increase, then the resistance of foil resistance foil gauge 12 reduces, and dynamic should
Become the output current amplitude increase of the detection foil resistance foil gauge of instrument 14, these final changes can be shown indirectly by binary channels
Ripple recorder 15 is observed；
(4) it is powered to drum brake 2, drum brake 2 is declutched, when drum brake 2 completes to declutch, brakes bullet
The decrement of spring 5 is maximum, i.e., the pressure that tripping spring 5 is applied on latch plate is maximum, then now the strain of latch plate 11 is maximum,
The elongation for the foil resistance foil gauge 12 being arranged on latch plate 11 is maximum, cross-sectional area is minimum, so now foil resistance
The resistance of foil gauge 12 is maximum, and the current signal amplitude that dynamic strain indicator 14 is exported is minimum；
(5) power supply of drum brake 2 is cut off, as shown in figure 3, binary channels electrographic recording instrument 15 records drum brake 2
It is t0 at the time of deenergization；
(6) as shown in figure 3, drum brake 2 power supply disconnect moment t0 after, dynamic strain indicator 14 input electric current
The amplitude of signal does not change within the t1 periods, and the strain of this explanation foil resistance foil gauge 12 does not have to become
Change, i.e. the decrement of tripping spring 5 does not change, and the reason for producing the phenomenon is：As shown in figure 4, in drum brake 2
The winding coil in portion is in energization and shutdown transient equivalent to one equivalent inductance L, equivalent inductance L and the circuit of drum brake 2
Continued flow resistance R turned on by sustained diode, constitute one closure RL loops, because equivalent inductance L is in drum brake
2 shutdown transients produce counter electromotive force, make electric current in the winding coil of drum brake 2 not pop-off, but slowly lead to
Continued flow resistance R dissipation is crossed, causing the electromagnetic attraction of drum brake 2 slowly reduces, when electromagnetic attraction and tripping spring 5
During spring dynamic balance, tripping spring 5 just starts to do return motion, as shown in figure 3, be t2 at the time of tripping spring 5 starts to reply,
I.e. after the t2 moment, tripping spring 5 just starts to reply, and drum brake 2 just starts band-type brake；
(7) with the reply of tripping spring 5, the decrement of tripping spring 5 is gradually reduced, and tripping spring 5 is applied to spring
Pressure on plate 11 is gradually reduced, and the strain of latch plate 11 is also gradually reduced, and the elongation of foil resistance foil gauge 12 gradually subtracts
Small, cross-sectional area becomes larger, resistance gradually starts to diminish, accordingly, the output current signal amplitude of dynamic strain indicator 14 by
Gradual change is big, as shown in figure 3, being presented as in binary channels electrographic recording instrument 15：After the t2 moment in a period of time, dynamic strain indicator 14
The amplitude of input current signal gradually increases；
(8) when drum brake 2 reaches specified braking moment, the decrement of tripping spring 5 reaches minimum, now brakes
The pressure that spring 5 is applied on latch plate 11 reaches minimum, and the strain of latch plate 11 reaches minimum, then foil resistance foil gauge 12
Length reach that minimum, cross-sectional area reaches greatly maximum, its resistance reaches minimum, accordingly, the output electricity of dynamic strain indicator 14
Stream signal amplitude reaches maximum, and after this, the strain of foil resistance foil gauge 12 no longer changes, then dynamic strain indicator 14
The amplitude of input current also no longer change, as shown in figure 3, above-mentioned change is showed in binary channels electrographic recording instrument 15
For：T3 moment, the amplitude of the input current signal of dynamic strain indicator 14 reaches maximum, and dynamic strain indicator 14 is defeated after the t3 moment
The amplitude for entering current signal keeps constant；
(9) it can be seen from the operation principle of drum brake 2, at the time of the decrement of tripping spring 5 reaches minimum, just
At the time of being that drum brake 2 reaches specified braking moment, i.e. the braking response time of the single of drum brake 2 braking is equal to drum
The power supply of formula brake 2 disconnect the moment to the decrement of tripping spring 5 reach minimum at the time of between time difference, equal to drum-type
The power supply of brake 2 disconnect the moment to latch plate 11 strain minimum at the time of between time difference, equal to the electricity of drum brake 2
Source disconnect the moment to the resistance of foil resistance foil gauge 12 reach minimum at the time of between time difference, equal to drum brake 2
Power supply disconnect the moment to the output current signal amplitude of dynamic strain indicator 14 reach maximum at the time of between time difference, then drum-type
The braking response time of the single of brake 2 braking shows as the t0 moment to the time at t3 moment in binary channels electrographic recording instrument 15
Difference, i.e. period t4, can directly read.
(10) four step (4)-(9) are repeated, the braking response time of No. four single of drum brake 2 brakings is read,
The average for finally taking the detected value of this five braking response times is the braking response time of final drum brake 2.
As it was previously stated, GB 7588-2003《Elevator is manufactured with installing safety standard》Regulation：It is all participate in braked wheel or
The brake mechanical part that disk applies brake force should be divided to two assemblings to set, two groups of mechanical parts of drum brake or so in the present embodiment
The braking response time detected respectively by step (1)-(10).
GB 24478-2009《Elevator traction machine》In be brake power-off signal to the definition of brake response time
The time difference of specified braking moment is reached, the present embodiment is detection object with drum brake 2, using with national regulations etc.
The power supply of the drum brake 2 of effect disconnect the moment to the decrement of tripping spring 5 reach minimum at the time of time difference, i.e., it is bulging
The power supply of formula brake 2 disconnect the moment to latch plate 11 strain minimum at the time of between time difference, i.e. drum brake 2 electricity
Source disconnect the moment to the resistance of foil resistance foil gauge 12 reach minimum at the time of between time difference, i.e. drum brake 2 electricity
Source disconnect the moment to the output current signal amplitude of dynamic strain indicator 14 reach maximum at the time of between time difference as drum-type
The braking response time of brake 2, so as to truly ensure that the accuracy of brake response time detection, finally
The braking response time of drum brake 2 can be directly read by binary channels electrographic recording instrument 15, be the t0 moment to t3 moment
Time difference, i.e. period t4.
The detection object of the present invention is not limited to the drum brake 2 in above-described embodiment, and current elevator brake is
Machine-electric-type electromagnetic brake, is all the driving force using the spring force of tripping spring as brake force, therefore the present invention is for current
