The realization details of the detection method of the elevator machine brake brake force of present embodiment is carried out below specific
Explanation, the following contents only for convenience of understand provide realization details, not implement this programme it is necessary.
Firstly the need of explanation, present embodiment is in traction machine, (traction machine is the power-equipment of elevator, also known as electric
Terraced host) on be integrated with multiple groups brake elevator brake force detection scheme.It is understood that with elevator applications feelings
Condition it is more complicated, three groups, four groups of even more multiple groups numbers may be integrated on some high-power or express elevator traction machine
Brake.And it is primarily directed to the case where one group of brake is only integrated on traction machine in the prior art, it is based on brake
The detection for carrying out brake force is dragged under stationary state by driver.Since the driving of elevator arrangement limits, so that this field skill
Art personnel usually carry out braking forces measuring as a whole to the elevator for being integrated with multiple groups brake to get the testing result arrived
For the testing result of the brake force under multiple groups brake collective effect so that relevant staff can not accurately learn it is specific every
The testing result of group brake braking force, and present embodiments provide for can be improved to examine elevator machine brake brake force
Survey the concrete scheme of the accuracy of result.
The detection method of elevator machine brake brake force in present embodiment is as shown in Figure 1, comprising:
Step 101, specify N group brake in wherein one group be used as test target brake, control target brake at
In on-position, and controls the brake other than target brake and be in non-brake device state.
Such as elevator includes two groups of brakes, respectively first group of brake and second group of brake, if specified should
First group of brake in two groups of brakes is test target brake, then controls first group of brake and be in on-position,
It can be understood as band-type brake state；And the effect that second group of brake does not stress is controlled, it is in non-brake state, it is understood that be
Open a sluice gate state.
It should be noted that one group of brake is equivalent to a brake, in this field, brake is described with " group " is
Standard saying.It is understood that a brake includes several components, one group of brake, a brake have been each meant
Brake in whole meaning, to avoid not knowing the problem, unification is indicated with " group " in the present embodiment.
Preferably, being in on-position in control target brake, and the brake controlled other than target brake is in
Other brakes after non-brake device state, before entering step 102, other than acceptable further test-target brake
Whether non-brake state is in really；If detecting the presence of brake is not at non-brake state, alert.In reality
In the application of border, it may appear that certain brakes itself exist abnormal and lead to not the case where being switched to non-brake state.This implementation
In example, by testing to whether target brake is in non-brake state, it can examine that there are on-position switching is different
Normal brake, alert prompt can make related personnel to should be in non-brake state to related personnel
And the brake for being practically at on-position uses corresponding measure, to exclude in the presence of abnormal brake to target brake
It is influenced caused by the accuracy of testing result, achievees the purpose that the accuracy for further increasing testing result.
Step 102, control elevator traction machine applies the first torque to test target brake with pre-set velocity.Wherein,
One torque is greater than preset threshold.
Step 103, the velocity of rotation and/or rotation distance of elevator traction machine are detected.
Preferably, after the velocity of rotation and/or rotation distance for detecting the traction machine, it can also be to the electricity detected
The velocity of rotation and/or rotation distance of terraced traction machine are judged, automatically analyze to obtain testing result, and tied according to detection
Fruit executes Preservation tactics.It does so, not only records the velocity of rotation and/or rotation distance of the elevator traction machine detected, may be used also
To record testing result.In the present embodiment, by obtaining testing result automatically according to detection data, improving to elevator traction
While the accuracy of brake braking forces measuring result, manpower is also saved, is improved to elevator machine brake system
The detection efficiency of power.Wherein, elevator machine brake Braking Force Detection System can be counted according to specified in professional standard
Be worth range perhaps related personnel input historical empirical data or related personnel setting detection data normal range (NR) into
Row automatically analyzes to obtain testing result, and the present embodiment is not especially limited this.
To the elevator traction machine detected velocity of rotation and/or rotation distance judge, obtain testing result
In step, the present embodiment provides following two concrete schemes:
In an arrangement, whether the velocity of rotation and/or rotation distance for judging traction machine meet preset requirement, then determine
The brake force grade of target brake is excellent；Otherwise, it is determined that the grade of the brake force of target brake is unqualified.
It specifically, can be only to the velocity of rotation of traction machine if only being detected to the velocity of rotation of elevator traction machine
Whether meet preset requirement under the action of the first torque to be judged, if the velocity of rotation meets preset requirement, determines mesh
It is excellent for marking the brake force grade of brake；Alternatively, if only being detected to the rotation distance of elevator traction machine, it can be only to traction
Whether the rotation distance of machine meets preset requirement under the action of the first torque is judged, if the rotation distance meets default want
It asks, then determines that the brake force grade of target brake is excellent.In addition, if both being detected to the velocity of rotation of elevator traction machine,
Again the rotation distance of traction machine is detected, then can pair elevator traction machine velocity of rotation and rotation distance in the first power
Whether meet preset requirement under the action of square to be judged, if velocity of rotation and rotation distance are all satisfied preset requirement, determine
The brake force grade of target brake be it is excellent, otherwise, it is determined that the grade of the brake force of test target brake is unqualified.This implementation
In example, it can detecte out the underproof brake of grade, can prevent the elevator for being integrated with underproof brake from still being thrown
Enter to use, to reduce a possibility that bringing risk to passenger.
In another scheme, if the velocity of rotation of traction machine and/or rotation distance meet preset requirement, target is determined
The brake force grade of brake is excellent；Otherwise, control elevator traction machine applies second to test target brake with pre-set velocity
Torque, the second torque are less than preset threshold；Detect the velocity of rotation and/or rotation of the elevator traction machine under the second moment loading
Distance determines to survey if the velocity of rotation of elevator traction machine and/or rotation distance meet preset requirement under the second moment loading
It is good for trying the grade of the brake force of target brake；Otherwise, it is determined that the grade of the brake force of target brake is unqualified.It is not difficult to send out
It is existing, in this scenario, the braking effect of brake is detected by applying traction machine compared to lesser second torque before, if
The velocity of rotation of traction machine and/or rotation distance meet preset requirement under the second torque, then may indicate that the target brake
Have certain brake force, relevant staff is answered the target brake application to demand braking force is lesser
With scene, or can also be by improving to improve its brake force to the brake.In the present embodiment, it can not only examine
Measure underproof brake, prevent the elevator for being integrated with underproof brake be still put into use and avoid to passenger with
A possibility that carrying out risk, it is thus also avoided that the brake of suboptimum is directly included into the underproof scope of grade, can be further improved
The accuracy of testing result can also improve the utilization rate of brake.
Preferably, different Preservation tactics can be corresponding with for the different brackets of elevator machine brake brake force.
As in second above-mentioned scheme, the grade of brake braking force can be divided into it is excellent, good, unqualified, then excellent corresponding with grade
Can be " without processing "；It can be for " break-off, prompting need repairing at engineer with the good corresponding processing rule of grade
Reason "；It can be " break-off is reminded and needs senior Maintenance Engineer's processing " with the unqualified corresponding processing rule of grade.So
It is without being limited thereto, or to be corresponding with the Preservation tactics of other modes, the present embodiment is not especially limited.
Step 104, the velocity of rotation and/or rotation distance of the elevator traction machine detected are recorded.
In present embodiment, after the velocity of rotation of traction machine and/or the detection data of rotation distance that record detects,
Elevator machine brake Braking Force Detection System can be by the detection data active reporting of record to default terminal, for example shows
Terminal is consulted convenient for related personnel, analysis is to obtain testing result；The detection data of record one can also be stored in specify
Address actively obtains detection data by related personnel from the address, then is analyzed and examined according to detection data by related personnel
Survey result.Related personnel can set the reporting schemes of detection data according to actual condition, and the present embodiment does not limit this specifically
It is fixed.Testing result or elevator machine brake braking forces measuring system are either obtained according to detection data by related personnel
System directly automatically analyzes to obtain testing result according to detection data, relevant staff is supplied to, in the guarantor of present embodiment
Within the scope of shield, it is not especially limited herein.
Compared with prior art, present embodiment by specify in N group brake wherein one group as target brake,
Only control target brake is in on-position, carries out braking forces measuring to the target brake, realizes to elevator brake
It is individually detected, records the detection data of current target brake detected after a test, avoid while to multiple groups
Elevator brake carries out detection to obtain the testing result of multiple elevator brakes on the whole, since what is obtained is single group braking
The testing result of device improves the accuracy of testing result；Again due to generally to elevator brake carry out individually detection compared to
The torque of required application is smaller when detecting simultaneously to multiple groups elevator brake, and therefore, the application can also share elevator original
Some output torques reduce the overload output when carrying out braking forces measuring, so as to making for hoisting elevator on the whole
Use operating condition.

Dynamic device B and third group brake C controls A and is in on-position, B and C are in if specified target brake is A for the first time
Non-brake state, after detecting to A, control A, B and C are completely in on-position；If second of specified target braking
Device is B, then controls B and be in on-position, and A and C are in non-brake state, after detecting to B, at control A, B and C whole
In on-position；If the specified target brake of third time is C, controls C and be in on-position, A and B are in non-brake shape
State, after detecting to C, control A, B and C are completely in on-position；Due to carrying out at least one to every group of brake
Secondary braking forces measuring, then testing process terminates.It is understood that when elevator includes that N in N brake is greater than 3, detection
Method is similar, also more rare in practical applications, no longer repeats one by one herein.
It is not difficult to find that present embodiment provide a kind of elevator machine brake brake force detection method, by
