Abstract
The invention provides an elevator control operation device comprising a receiver unit and a long period taphrogeny detector. The receiver unit receives urgent earthquake rapid reports input from outside including earthquake source information and earthquake seismic degree information. The long period taphrogeny detector detects a long period taphrogeny and outputs a signal. A control unit enables an elevator car to stop at a nearest floor, open the elevator door to make the elevator in a stand by state when the control unit judges the earthquake source is in a predefine object area from the received urgent earthquake report and the seismic degree of the earthquake is above a specified value, and switches to the predefine long period taphrogeny control operation when the control unit judges that the long period taphrogeny detector outputs signals within a given time from the earthquake starts, and enables the elevator to return to normal when the control unit judges that the long period taphrogeny detector does not output signals within the given time from the earthquake starts.
Description
Technical field
The elevator that the present invention relates to a kind of generation of exploration seismic and carry out earthquake controlled operation is used the control running gear.
Background technology
In the ordinary course of things, be provided with the obligated earthquake detector that is provided with of building of elevator, when detecting earthquake, elevator switched to earthquake controlled operation through earthquake detector.
Different and different according to the function of elevator by class with the earthquake detector that obligation is set; In not having the conventional lift of quick traffic coverage, need to be provided with these the 2 kinds of detectors of low S wave detector that are used for surveying the low S wave detector of spy of the low especially main motion of acceleration/accel (S ripple) and survey the low S ripple of acceleration/accel.At this, so-called spy is low, and the S wave detector is not meant the detector that low earthquake is all surveyed to all acceleration/accels, and is meant the detector that the earthquake with the acceleration/accel that needs the earthquake controlled operation of startup is surveyed.On the other hand, low S wave detector is meant that to the earthquake of acceleration/accel more than setting value in the earthquake with the acceleration/accel that needs the earthquake controlled operation of startup be the detector that so-called violent earthquake is surveyed.And, also can use the P wave detector of the initial stage fine motion (P ripple) of exploration seismic to replace special low S wave detector.
Through above-mentioned 2 kinds earthquake detector is arranged in the building that is provided with elevator, the earthquake controlled operation that elevator is predesignated according to the result of detection of each earthquake detector.For example, detect earthquake, but low S wave detector carries out the 1st grade of other earthquake controlled operation when not detecting earthquake at the low S wave detector of spy.Concrete method is after making the lift car that carries out lifting action rest in nearest floor, opens the car door of the lift car of having stopped and the elevator lobby door of the floor that lift car is stopped.After this, elevator is automatically restoring to normal operation through behind the certain hour.
On the other hand, when having detected the earthquake, when low S wave detector has also detected earthquake, carry out the 2nd grade of other earthquake controlled operation except the low S wave detector of spy.Concrete method is after making the lift car that carries out lifting action be accommodated to nearest floor, opens the car door of the lift car of having stopped and the elevator lobby door of the floor that lift car is stopped.After this, after having passed through certain hour, still make elevator keep the operation halted state, and after having carried out safety verification through the maintainer and having recovered the adjustment operation, recover normally operation.
But, through research, find when adopting the earthquake detector of above-mentioned acceleration detection mode earthquake, might survey the seismic motion that but seismic motion that cycle long little less than acceleration/accel promptly rocked with the cycle of several seconds to tens second lentamente.Therefore; When hoist trunk that the long period seismic motion causes being provided with building or the elevator of elevator taking place rock slowly; Even big deflection has taken place in building and hoist trunk etc.; But, do not switch to earthquake controlled operation and proceed normal situation about moving so elevator can occur because the earthquake detector of above-mentioned acceleration detection mode is surveyed less than this earthquake.
When elevator moves under the state of big deflection takes place owing to rock slowly repeatedly for the hoist trunk of building and elevator etc.; The hoist cable of elevator (comprising main hoist cable, assisted suspension cable and speed controller rope) can produce resonance along with the deflection of building and hoist trunk etc.; And the hoist cable that has produced resonance can bump with the wall of lift car, counterbalanced weight or elevator lifting channel, thereby possibly damage lift facility.If lift facility is in operation as stated and is damaged, lift car then might take place carry out emergency braking because of the signal from the detector that detects this damage, thereby cause elevator passenger to be closed in the situation in the lift car.Especially when the long period earthquake has taken place, because this kind earthquake is easy and the eigentone of high building forms resonance, so may cause big loss.
For this reason; As prior art; Seismic motion detects to long period, and according to the testing result of this long period seismic motion the technology that elevator switches to the earthquake controlled operation of predesignating of long period has been realized practicability (for example with reference to patent documentation 1 and 2).
