Detailed description of the invention
Referring to accompanying drawing, embodiments of the present invention are described.
As shown in Figure 1, the related lift facility of one embodiment of the present invention is configured to lift car 2 and is connected by main hoisting rope 4 in hoist trunk 1 with counterbalanced weight 3, and can be along not shown guide rail oscilaltion.In the Machine Room 5 that is formed on hoist trunk 1 top, be provided be wound with the winch 6 of main hoisting rope 4, for control this winch 6 etc. control panel 7, detect vibrations instrument 8 and the governor 10 that is wound with speed controller rope 9 etc. that building rocks.In addition, in hoist trunk 1, be provided with: compensates rope 11, for compensating the weight difference of main hoisting rope 4, while observation from winch 6 sides, compensates rope 11 is connected between lift car 2 and counterbalanced weight 3; For the stern fast 12 of powering to lift car 2; Be arranged on the shock absorber 13 of the bottom of lift car 2 or counterbalanced weight 3; And for supporting the support 14 etc. of equipment in not shown guide rail and other hoist trunk etc.In addition, be provided with and rock restraining device 17 on the top of lift car 2, it in the time meeting defined terms, stretches to suppress rocking of main hoisting rope 4 as described later towards top.
Fig. 2 is the enlarged drawing of the main portion of the lift facility shown in Fig. 1, as shown in Figure 2, is provided with crosshead 16 on the top of the car frame 15 of lift car 2, and the above-mentioned restraining device 17 that rocks is mounted on this crosshead 16.This rocks restraining device 17 and is configured to have: the telescoping mechanism part 18 of convergent-divergent (pantograph) formula, and the base portion side of its below is fixed on crosshead 16; Actuating device 19, it drives this telescoping mechanism part 18 with air pressure, hydraulic pressure or alternate manner and makes it flexible; Actuating device control part 20, it,, in the time of the expanding-contracting action signal receiving from control panel 7, makes actuating device 19 carry out expanding-contracting action; And rocking of being made up of rubber etc. suppress member 21, it is arranged on the position by flexible side of telescoping mechanism part 18 tops, and main hoisting rope 4 inserts in this through hole that rocks inhibition member 21 central parts.In the time that elevator carries out normal oscilaltion, rocking inhibition member 21 can not interfere with main hoisting rope 4, and in the time having there is large rocking in main hoisting rope 4 under the extended configuration of telescoping mechanism part 18, main hoisting rope 4 and the endless inner wall collision of rocking inhibition member 21, brought into play and rocked inhibit function by collision repeatedly.
The vibrations instrument 8 that detection building shown in Fig. 1 rocks has the function of the acceleration/accel that detects orthogonal horizontal direction (X, Y-direction), is sent in the arithmetic section 22 being arranged in control panel 7 from the detection signal of this vibrations instrument 8.Arithmetic section 22 is configured to according to the acceleration signal by the horizontal direction that detects of vibrations instrument 8, rocks maximum this assumed condition computing maximum relative displacement amount that reaches of rocking of the main hoisting rope 4 that produces according to the assumed condition of this lift facility because of hoist trunk 1.This arithmetic section 22 is after the maximum relative displacement amount of belly of shaking amplitude maximum that calculates main hoisting rope 4, the relative shift threshold value of this maximum relative displacement amount and predefined regulation is compared, and this comparative result is sent in control operation control part 23, this control operation control part 23 is receiving after this comparative result, according to this comparative result, lift car 2 is carried out to control operation.
For convenience of explanation, operating to example with the following control of stopping describes., in arithmetic section 22, basis is calculated maximum relative displacement amount from the acceleration signal of vibrations instrument 8, the maximum relative displacement amount that judges main hoisting rope 4 is for example, below the relative shift threshold value (20cm) of regulation or has exceeded the relative shift threshold value of this regulation, and judged that signal sends in control operation control part 23, the control operation control part 23 that receives this judgement signal carries out the control operation in two stages according to this judgement signal, be specifically, in the time of the judgement signal receiving from arithmetic section 22 below the relative shift threshold value of the maximum relative displacement amount that represents main hoisting rope 4 at afore mentioned rules, control operation control part 23 comprises moves to lift car 2 can to reduce the rocking of operation of the position of the maximum relative displacement amount of main hoisting rope 4 to suppress control operation, in the time that the maximum relative displacement amount that receives expression main hoisting rope 4 from arithmetic section 22 has exceeded the judgement signal of relative shift threshold value of afore mentioned rules, the control operation of stopping that control operation control part 23 makes lift car 2 take refuge and operation is stopped to nearest floor.
The control operation of the control operation control part 23 while vibrations instrument 8 being detected to building rocks referring to the diagram of circuit shown in Fig. 3 describes.
In the time that the vibrations instrument 8 monitoring all the time detects rocking of building in step S1, in step S2, detect in lift car, whether there is passenger, and in the time passenger being detected, in step S3, make lift car move to elevator under nearest floor relief passenger.In the situation that passenger not detected, do not stop nearest floor.Meanwhile, arithmetic section 22 in step S4 according to the acceleration signal of horizontal direction from vibrations instrument 8, be maximum this assumed condition computing maximum relative displacement amount α according to the relative shift that rocks belly place of main hoisting rope 4, and judge that the maximum relative displacement amount α calculating is for example, below the relative shift threshold value a (20cm) of regulation or has exceeded the relative shift threshold value a of this regulation in step S5, in the time that the result of this judgement represents that maximum relative displacement amount α is below the relative shift threshold value a of regulation, be that the maximum relative displacement amount α of main hoisting rope 4 is when smaller, the control operation control part 23 that receives this judgement signal comprises that at step S6 the inhibition control of rocking of the operation that makes lift car 2 move to the position of the relative shift that can reduce main hoisting rope 4 moves.
The position of the relative shift that can reduce this main hoisting rope 4 that lift car 2 moves to, be for example maximum this assumed condition at the relative shift that rocks belly place as main hoisting rope 4, when the length setting of the main hoisting rope 4 when lift car 2 is positioned to orlop is the length of main hoisting rope 4, refer to the position that lift car 2 moves to towards the direction of the contraction in length of main hoisting rope 4, more specifically say the position of the half of the length of predefined main hoisting rope 4, or with roughly corresponding intermediate floor position, this position.These positions are not limited in predefined position, also can be in the time that above-mentioned arithmetic section 22 calculates maximum relative displacement amount α, calculate the belly of the shaking amplitude maximum of main hoisting rope 4, and near position this belly or this belly is as the position of maximum relative displacement amount that can reduce main hoisting rope simultaneously.
Above-mentioned steps S5 is configured to maximum relative displacement amount α to main hoisting rope 4 and the relative shift threshold value a of regulation compares, and whether detect be α≤a.In the case of the maximum relative displacement amount α of main hoisting rope 4 is quite little, also can be arranged to not carry out above-mentioned rocking and suppresses control operation.Now, if suppress the relative shift lower threshold in control when operation and be set as b not rocking, also can be arranged in whether in step S5, detect be b < α≤a.
By rock suppress control operation make lift car 2 move to assigned position before or afterwards, the actuating device control part 20 shown in Fig. 2, in step S7, receives signal from control operation control part 23, and sends stretching signal to actuating device 19.Actuating device 19 is receiving after stretching signal, for example, make the piston side of this actuating device 19 extend and the telescoping mechanism part 18 of pantographic is stretched towards top, further moves towards upper portion thereby make to rock inhibition member 21.Thus, the main hoisting rope 4 rocking is in the horizontal direction by repeatedly making to rock and reduce with rocking the ring-type internal perisporium collision that suppresses member 21, compared with rocking the occasion that nature reduces, can suppress at short notice to rock.
Carry out after above-mentioned computing at arithmetic section 22, in the situation that having passed through specified time, arithmetic section 22 is again according to carrying out computing from the signal of vibrations instrument 8, in the case of detect for the maximum relative displacement amount α of main hoisting rope 4 become quite little, or in the case of there is no rocking detection signal from vibrations instrument 8, or the moment in the case of other has been endowed restoring signal, in step S8, detect this restoring signal, the rocking of operation control part 23 of decontroling in step S9 suppressed control operation, and returns to normal operation.Now, the control operation control part 23 that restoring signal detected sends to recovery actuating signal in actuating device control part 20, the actuating device control part 20 that receives this recovery actuating signal makes actuating device 19 move in the opposite direction under the extended configuration shown in Fig. 2, telescoping mechanism part 18 is dwindled, to get back to the normal condition of Fig. 1.
So, occurred long size members after the end such as earthquake be main hoisting rope 4 in long-time, continue to rock phenomenon time, can detect by arithmetic section 22 the intrinsic phenomenon of this lift facility, if less rock of maximum relative displacement amount α below the relative shift threshold value a of regulation, can suppress control and operate in and in the short time, forcibly suppress rocking of main hoisting rope 4 by above-mentioned rocking, thereby can shorten the required time of normal operation that returns to.
On the other hand, according to the judgement of step S5, exceed in the case of being judged as maximum relative displacement amount α the relative shift threshold value a of regulation, control operation control part 23 is made and is difficult to be suppressed control and moved to suppress the judgement that main hoisting rope 4 rocks by above-mentioned rocking, and the control operation of stopping in step S10, lift car 2 is taken refuge also out of service to nearest floor.After this,, the restoring signal sending detected after maintenance etc. finishes in step S8 time, make lift facility return to normal operation.
In service in this control of stopping, rock from above-mentioned that to suppress control operation different, do not suppress member 21 and move towards top rocking rocking in restraining device 17 by telescoping mechanism part 18.Therefore, rock suppress member 21 be positioned at main hoisting rope 4 by near the position end of lift car 2 sides, not can because of main hoisting rope 4 occur large rock damaged.
In step 10, in the situation that stopping control operation, compared with rocking the situation that suppresses control operation, the maximum relative displacement amount α of the main hoisting rope 4 calculating in arithmetic section 22 is larger, especially the belly of the shaking amplitude maximum of main hoisting rope 4 likely with hoist trunk 1 in equipment interfere.Therefore, in this case, also can make lift car 2 move to the control operation of nearest floor (near for example off-resonance floor 1/3rd of the height of near the off-resonance floor 1/3rd of the length of main hoisting rope 4 position or building position), make main hoisting rope 4 in off-resonance state by this control operation, suppress thus rocking of main hoisting rope 4.In the case of near lift car 2 is positioned at the intermediate floor of building or near the position of the half of the length of main hoisting rope 4, a natural period natural period easy and building that is less than speed controller rope 9 and the compensates rope 11 etc. of main hoisting rope 4 due to tension force approaches, or approach with the value of approaching of a natural period of building, so speed controller rope 9 and compensates rope 11 etc. easily shake, therefore, preferably nearest floor is set as than near the floor of 1/3rd of the length that is positioned at main hoisting rope 4 of face position or be positioned at the floor of 1/3rd position of the height of building closely intermediate floor, difference between natural period and a natural period of building of speed controller rope 9 and compensates rope 11 etc. is increased, or the difference between the value of approaching of a natural period of this natural period and building is increased.And, in the time having there is passenger and be closed in the situation in lift car, because lift car is positioned at than the closely position of face of intermediate floor, so can also shorten the rescue required time of passenger.
The control of stopping at step S10 is in service, because the restraining device that rocks that can also be arranged to by other suppresses rocking of speed controller rope 9 and compensates rope 11 etc., so can be also predefined other nearest floor by nearest storey setting.
According to above-mentioned lift facility, below the relative shift threshold value a that the maximum relative displacement amount α of the main hoisting rope 4 calculating in arithmetic section 22 is specifying time, control operation control part 23 rocks and suppresses control operation, make lift car 2 move to the position that restriction main hoisting rope 4 rocks, by the inhibition member 21 that rocks that rocks restraining device 17, rocking of main hoisting rope 4 suppressed, thus, main hoisting rope rock in the case of building rock decay after will continue the long period, not needing to arrange complicated structure just can utilize the position of lift car 2 and rock restraining device 17 and at short notice rocking of main hoisting rope 4 suppressed, can shorten and make elevator return to the required time of normal operation.In addition, due to the top of rocking restraining device 17 and be arranged on lift car 2 of preventing that main hoisting rope 4 rocks, so the relative shift threshold value a that has exceeded regulation at the maximum relative displacement amount α of the main hoisting rope 4 that calculated by arithmetic section 22, rocking restraining device 17 and be not the rocking of central part of rocking of the main hoisting rope 4 to significantly rocking suppresses, but the rocking of main hoisting rope 4 of the position near lift car 2 one sides suppressed, thereby can realize fairly simple structure.
And, be configured to make to suppress by telescoping mechanism part 18 owing to rocking restraining device 17 that main hoisting rope 4 rocks rocks and suppress member 21 and further move towards top, so when rock inhibition control operation in order to suppress rocking of main hoisting rope 4, further move towards the upper section of lift car 2 by making to rock inhibition member 21, can make to rock and suppress member 21 and with the top position of the anchor portion apart from each other by lift car 2 sides of main hoisting rope 4, rocking of main hoisting rope 4 suppressed, so can further effectively suppress rocking of main hoisting rope 4.
According to above-mentioned lift facility, in the time that the maximum relative displacement amount α of the main hoisting rope 4 calculating in arithmetic section 22 has exceeded the relative shift threshold value a of regulation, the control operation of stopping of control operation control part 23, makes lift car 2 move to predefined nearest floor and takes refuge.So; even in the time having occurred to use rocking of lift car 2 tops to suppress situation that member 21 also cannot suppress rocking of main hoisting rope; do not carry out above-mentioned damping action; so can not cause irrational vibration and load to rocking inhibition member 21 and lift car 2 under this kind of state, can protect existing building.In addition, owing to not needing to use the firm restraining device 17 that rocks that can bear above-mentioned situation, thus increase unnecessary weight can not to lift car 2, and there is no need the structure member of the drive system that changes other.
In addition, in the above-described embodiment, the relative shift threshold value of regulation is set to 20cm, but the present invention is not only for this, can be arbitrary value by the relative shift Threshold of regulation.In addition, in the above description, use a relative shift threshold value a that control operation is divided into rocking and suppress control operation and the control of stopping moves to carry out the control operation in two stages, carry out control operation but also can be divided into three phases.In addition, in the above description, arithmetic section 22 is arranged in control panel 7, but arithmetic section 22 also can be arranged in the housing of vibrations instrument 8.
