Fig. 1 is the figure that the summary of the related elevator device of expression embodiment constitutes example.The formation of elevator device 1 comprises: 2,2 brake equipment 3A of towing machine, 3B, impulse deviser 4 and control setup 5.
Towing machine 2 is rolled not shown main rope through being rotated, and the not shown car and the balance weight that are connected in main rope are gone up and down in not shown lift path by bucket type.Towing machine 2 is electrically connected with control setup 5, moves control through the electric power of supplying with from control setup 5.
2 brake equipment 3A, 3B brake towing machine 2.That is to say that brake equipment 3A, 3B through towing machine 2 is braked, make car stop thus.The formation of brake equipment 3A, 3B comprises drg 31A, 31B and switch 32A, 32B.
Drg 31A, 31B through contacting with towing machine 2, make the rotation of towing machine 2 stop thus.Drg 31A, 31B are for example magnet stopper, are controlled to be arbitrary state of the open state of braking mode that towing machine 2 is braked or opening (release) towing machine 2 by work through control setup 5.At this, control setup 5 through control respectively with ON (connections)/OFF (disconnection) state of drg 31A, the cooresponding electromagnetism switch circuit controller of 31B 6A, 6B, carry out the work of drg 31A, 31B thus and control.Electromagnetism switch circuit controller 6A, 6B, the electric power that under the ON state, will come from drg power supply 7 is supplied with to drg 31A, 31B, under the OFF state, will supply with to the electric power of drg 31A, 31B from drg power supply 7 and break off.Electromagnetism switch circuit controller 6A, 6B be the ON state then drg 31A, 31B be open state, electromagnetism switch circuit controller 6A, 6B are that then drg 31A, 31B are braking mode to the OFF state.
Switch 32A, 32B are drg abnormality detection mechanism, detect the unusual of drg 31A, 31B.Switch 32A, 32B are provided with drg 31A, 31B respectively accordingly.Switch 32A, 32B are contact switch, are electrically connected on control setup 5.Switch 32A, 32B contact with each other to "on" position, are the ON state at the open state lower contact of drg 31A, 31B, are separated from each other to off-state, are the OFF state at the braking mode lower contact of drg 31A, 31B.Therefore, if drg 31A, 31B are open state, then switch 32A, 32B are to control setup 5 output brake clearing signals.
Impulse deviser 4 detects the slew mode of towing machine 2.Impulse deviser 4 is electrically connected with control setup 5, and the rotating signal of the rotation of towing machine 2 is followed in output.At this, control setup 5 can obtain anglec of rotation, rotative speed of towing machine 2 etc. through the output signal that comes from impulse deviser 4.
Control setup 5 carries out the work control of brake equipment 3A, 3B and the operation control of towing machine 2.Control setup 5; As common operation; Electromagnetism switch circuit controller 6A, 6B are made as the ON state supply to drg 31A, 31B with the electric power that will come from drg power supply 7; Under the open state of drg 31A, 31B, carry out the operation control of towing machine 2 based on the calling registration with by impulse deviser 4 detected slew mode.Control setup 5 is electrically connected on monitor unit 8, and this monitor unit 8 is arranged at the caretaker room that has omitted the graphic works that is provided with elevator device 1 and/or is arranged at the outer central monitoring position of works etc.Monitor unit 8 is kept watch on from the running state or the error state of the elevator device 1 of control setup 5 outputs, if elevator device 1 is error state then operating personal is given the alarm.
Control setup 5 is when moving, if through some the unusual of cooresponding drg that detect in 2 switches, then all drg work is controlled to be braking mode usually.Under this state; Control setup 5; Towing machine 2 is moved control make it produce the rotating torques T more than the predetermined rotating torques Tt, under the situation that detects towing machine 2 rotations through impulse deviser 4, it is unusual to be judged as and to detect the corresponding drg of the unusual switch of drg.On the other hand, control setup 5 is detecting under the towing machine 2 non-rotary situation, is judged as that to detect the unusual switch of drg unusual.At this, so-called predetermined rotating torques Tt is than making 1 drg act on the big and value littler than the braking torque that makes 2 drgs act on towing machine 2 of braking torque of towing machine 2 in this embodiment.For example predetermined rotating torques Tt is preferably about 1.5 times of the braking torque that makes 1 drg act on towing machine 2.
In addition, control setup 5, to detect the unusual switch of drg unusual if be judged as, and then will be controlled to be open state with the corresponding drg work of unusual switch.And control setup 5 makes the electric current that in this embodiment, supplies to unusual switch promptly detect the electric current of current ratio when common and increases, and judges whether once more to have detected the unusual of drg through unusual switch.Control setup 5 does not detect the unusual of drg if be judged as through unusual switch, then makes to detect electric current and get back to the electric current when common.
The method for detecting abnormality of the brake equipment that next, carries out about the related elevator device 1 of this embodiment describes.Fig. 2 is the diagram of circuit of the method for detecting abnormality of the brake equipment that carries out of expression embodiment related elevator device.Fig. 3 is the diagram of circuit of the method for detecting abnormality of the brake equipment that carries out of expression embodiment related elevator device.In addition, " 1 " shown in Figure 2 links to each other with " 1 " shown in Figure 3.
At first, whether unusually control setup 5 judges some (the step S1) among drg 31A, the 31B.At this, control setup 5 through judging whether the not some output brake clearing signals from switch 32A, 32B, is judged some whether unusual among brake equipment 3A, the 3B thus.
Next, control setup 5 if be judged as some unusual (step S1 certainly) among brake equipment 3A, the 3B, then is made as braking mode (step S2) with all drg 31A, 31B.At this, control setup 5 is the OFF state with all electromagnetism switch circuit controller 6A, 6B from the ON state transformation, breaks off from drg power supply 7 and supplying with to the electric power of drg 31A, 31B, and all drg 31A, 31B work are controlled to be braking mode.That is to say that control setup 5 during for unusual urgent of the some existence in being judged as brake equipment 3A, 3B, stops car, through all brake equipment 3A, 3B towing machine 2 is braked.In addition, control setup 5 if be judged as any all normal (step S1 negates) among brake equipment 3A, the 3B, then carries out till step S1 some unusual in brake equipment 3A, 3B repeatedly.
Next, control setup 5 judges whether car stops (step S3).At this, control setup 5 through judging whether through all brake equipment 3A, 3B the rotation of towing machine 2 to be stopped, judges thus whether car stops.
Next, control setup 5 stops (step S3 certainly) if be judged as car, judges then whether towing machine 2 rotates (step S4).At this, control setup 5 is through judging whether that having detected towing machine 2 rotations through impulse deviser 4 judges whether towing machine 2 rotates.In addition, after car just stopped, towing machine 2 did not rotate, and did not rotate (step S4 negates) so be judged as towing machine 2 through control setup 5.In addition, control setup 5 does not stop (step S3 negates) if be judged as car, then carries out step S3 repeatedly till car stops.
Next, control setup 5 does not rotate (step S4 negates) if be judged as towing machine 2, judges then whether the rotating torques T of towing machine 2 is predetermined rotating torques Tt above (step S5).In addition, after car just stopped, the operation of the towing machine 2 that is undertaken by control setup 5 did not begin, so be judged as rotating torques T not predetermined more than the rotating torques Tt (step S5 negates) through control setup 5.
Next, control setup 5 is if the rotating torques T that is judged as towing machine 2 then carries out the operation control (step S6) of towing machine 2 not for predetermined rotating torques Tt above (step S5 negates).At this, 5 pairs of towing machine 2 supply capabilities of control setup make it to produce rotating torques T.In addition, after car just stopped, the operation of the towing machine 2 that is undertaken by control setup 5 control did not begin, so the operation control of the towing machine 2 that beginning is undertaken by control setup 5.At this, control setup 5 carries out the operation control of towing machine 2, makes the rotating torques T ladder property ground of towing machine 2 increase.That is to say that control setup 5 moves control, make the rotating torques T of towing machine 2 become more than the predetermined rotating torques Tt.
In addition, control setup 5 if be judged as towing machine 2 rotations (step S4 certainly), judges then whether switch 32A has detected (step S7) unusually.At this, become under the situation more than the predetermined rotating torques Tt at the rotating torques T that moves the towing machine 2 of control by control setup 5, during towing machine 2 rotations, do not make some among drg 31A, the 31B to towing machine 2 effect braking torques.Therefore, control setup 5 can be judged as some unusual among drg 31A, the 31B.
Next, control setup 5 has detected unusually (step S7 certainly) if be judged as switch 32A, then is judged as the normal but drg 31A unusual (step S8) of switch 32A.Control setup 5 does not detect unusually (step S7 negate) if be judged as switch 32A, then is judged as the normal but drg 31B unusual (step S9) of switch 32B.Then, control setup 5 stops elevator device 1, is that the information and the error state of unusual drg outputs to monitor unit 8 (step S10) in the lump with particular decision.
In addition, control setup 5 is if the rotating torques T that is judged as towing machine 2 then is judged as all drg 31A, 31B normal (step S11) for predetermined rotating torques Tt above (step S5 certainly).At this, become under the situation more than the predetermined rotating torques Tt at the rotating torques T that moves the towing machine 2 of control by control setup 5, when towing machine 2 did not rotate, all drg 31A, 31B were to towing machine 2 effect braking torques.Therefore, can be judged as all drg 31A, 31B normal for control setup 5.
Next, control setup 5 judges whether switch 32A has detected (step S12) unusually.
Next, control setup 5 has detected unusually (step S12 certainly) if be judged as switch 32A, then is judged as the normal but switch 32A unusual (step S13) of drg 31A.
Next, control setup 5 increases the detection electric current (step S14) of switch 32A.
Next, control setup 5 is made as open state (step S15) with drg 31A.At this, control setup 5 becomes the ON state with electromagnetism switch circuit controller 6A from the OFF state, begins once more to supply with to the electric power of drg 31A from drg power supply 7, and drg 31B is the previous status of braking mode, drg 31A is worked is controlled to be open state.Therefore, switch 32A detects under the state after electric current increases at it, and the contact contacts with each other.At this; The situation that switch 32A is unusual comprises following situation: for example since contact surface be formed with insulating coating film and/or dust arranged between the contact; Because of contact accidental bad contact each other causes and can not switch on, the drg clearing signal is not outputed to control setup 5.Therefore, detect the electric current of current ratio when common and increase, might between the contact, advance to penetrate spark thus, can remove the insulating coating film that is formed at contact surface and/or the dust between between the contact through making.In addition, through changing normal drg 31A into open state from braking mode, switch 32A also in fact from the OFF state to the work of ON state, might be able to remove dust between between the contact etc.That is to say that control setup 5 through drg 31A is made as open state, is carried out the cleaning for switch 32A under the state that has increased the detection electric current.
Next, control setup 5 judges whether switch 32A has detected (step S16) unusually.
