And then hold-down arm 55a, 55b can rotate between the 2nd position P2 shown in the 1st position P1 and Fig. 7 shown in Fig. 6.Under the 1st position P1, hold-down arm 55a, 55b level between the 1st guide rail 3a, 3b is given prominence to.Under the 2nd position P2, hold-down arm 55a, 55b, vertically to erect along the mode of the 1st guide rail 3a, 3b, keep out of the way between the 1st guide rail 3a, 3b.
And then hold-down arm 55a, 55b are driven in the mode of the one party optionally turning to the 1st position P1 and the 2nd position P2 by actuator 57a, 57b that such as hydraulic actuating cylinder is such.When hold-down arm 55a, 55b turn to the 1st position P1, this hold-down arm 55a, 55b are hooked in below the flange part 33 of the support beam 32a forming swing prevention mechanism 30.Thus, the position of readiness L1 stoping mechanism 30 to be held in the topmost of elevating road 2 is swung.
According to the present embodiment, the drive division of actuator 57a, 57b is electrically connected with the operation control section 19 of described control setup 18.Operation control section 19 by rock control control part 20 phugoid detected time, the drive division of actuator 57a, 57b is exported and makes hold-down arm 55a, 55b turn to the signal of the 2nd position P2 from the 1st position P1.
Meanwhile, operation control section 19 pairs of motors 39 export and make the motor 39 of the 1st to the 4th guiding device 35a, 35b, 35c, 35d carry out the signal of action as electrical generator.
Then, add the diagram of circuit shown in Fig. 8, the action of the elevator 1 when building effect has phugoid is described.
The control control part 20 that rocks of control setup 18 judges whether to create phugoid at building in step sl.In the present embodiment, rock control control part 20 and judge whether rock perceptron 21 detects with such as earthquake or the high wind phugoid as major cause based on from the acceleration/accel rocked rocking the building that perceptron 21 exports.
Rocking control control part 20 when being judged as creating phugoid, entering and making elevator 1 from the step S2 usually changing rectangular controlled operation into.In step s 2, rock control control part 20 pairs of operation control section 19 and export the instruction that the running of elevator 1 is stopped.Then, operation control section 19 controls winch 7 based on from the instruction of rocking control control part 20, thus makes cage 5 stop at closest layer, and maintains the state that winch 7 is stopped.
Rocking control control part 20 when being judged as not producing phugoid, repeatedly carrying out step S1, until produce phugoid.
Then, rock control control part 20 enter judge based on earthquake high wind building rock the step S3 whether restrained.Rock control control part 20 be judged as building rock restrain time, based on the instruction from operation control section 19, actuator 57a, 57b of stop motion mechnism 54 make hold-down arm 55a, 55b turn to the 2nd position P2 from the 1st position P1, and the motor 39 of the 1st to the 4th guiding device 35a, 35b, 35c, 35d carries out action as electrical generator.
Turn to the 2nd position P2 by hold-down arm 55a, 55b from the 1st position P1, swing and stop the maintenance of mechanism 30 to be removed.Its result, enters the step S4 swinging prevention mechanism 30 and start because of deadweight to decline from position of readiness L1 towards cage 5.
In the stage of step S4, although rocking of building restrains, the main rope 8 cage 5 being hung on elevating road 2 swings in the transversely continuation of elevating road 2.Especially, under the state on the lower of the pars intermedia along short transverse that cage 5 is positioned at than elevating road 2, the total length of the section 1 8a of main rope 8 increases, and thus the amplitude of fluctuation of the section 1 8a of main rope 1 becomes large.
If remove the maintenance swinging and stop mechanism 30 in step s 4 which, then swing and stop mechanism 30 to decline along the 1st guide rail 3a, 3b because of deadweight.Now, because the outer peripheral face of the 1st roller 38a of the 1st to the 4th guiding device 35a, 35b, 35c, 35d is flexibly pressed the top edge 3d being attached to the sword 3c of the 1st guide rail 3a, 3b, so input rotational force from the 1st roller 38a to motor 39, motor 39 carries out work as electrical generator.
Thus, produce regenerative brake at motor 39, swing prevention mechanism 30 bears braking force and slowly declines towards cage 5 in elevating road 2.
When swinging prevention mechanism 30 and declining, the section 1 8a of main rope 8 can pass through the inserting hole 51 of cable guides 50a, 50b.Although cable guides 50a, 50b allow main rope 8 to move along the short transverse of elevating road 2, retrain the action transversely of main rope 8 in elevating road 2.
Its result, even if section 1 8a cage 5 being hung on the main rope 8 of elevating road 2 is subject to such as earthquake, the impact of high wind and transversely significantly swinging in elevating road 2, the swing of main rope 8 also forcibly can be suppressed in the section 1 8a of main rope 8 is by the process of cable guides 50a, 50b.
When swinging prevention mechanism 30 and arriving on cage 5, enter step S5.In step s 5, operation control section 19 makes battery 40 supply electric power to motor 39, drives the 1st roller 38a to the direction contrary with when declining.Thus, by the contact resistance produced between the 1st roller 38a and the 1st guide rail 3a, 3b, swing and stop mechanism 30 to start to rise from the top of cage 5 towards position of readiness L1.
Swinging in the process stoping mechanism 30 to be risen, the section 1 8a of main rope 8 also can pass through the inserting hole 51 of cable guides 50a, 50b, and main rope 8 thus also can be suppressed in the action transversely of elevating road 2.
When swinging prevention mechanism 30 and arriving position of readiness L1, actuator 57a, 57b of stop motion mechnism 54 make hold-down arm 55a, 55b turn to the 1st position P1 from the 2nd position P2.By this rotation, hold-down arm 55a, 55b are hooked in below the flange part 33 of support beam 32a, stop mechanism 30 to be held in position of readiness L1 swing.
After stoping mechanism 30 to be held in position of readiness L1 swing, enter step S7.In the step s 7, operation control section 19 is removed the rectangular controlled operation of elevator 1 and again starts usual running.
According to the 1st embodiment, when the elevator 1 stopped under because of rectangular controlled operation enters Restoration stage, the swing being held in the topmost of elevating road 2 stops mechanism 30 to decline along the 1st guide rail 3a, 3b.Thus, rocking the main rope 8 also continuing to swing in elevating road 2 after convergence and by the inserting hole 51 of cable guides 50a, 50b, thus can retrain the swing transversely of main rope 8 in elevating road 2 by this cable guides 50a, 50b at building.
Thus, the swing of the main rope 8 in elevating road 2 can be made to restrain rapidly, the elevator 1 that running can be made to stop recovers running usually as early as possible.Therefore, it is possible to shortening elevator 1 runs to the time till entry into service again from stopping.

[the 2nd embodiment]
Fig. 9 to Figure 11 discloses the 2nd embodiment.2nd embodiment is different from the 1st embodiment in the structure of four guiding devices stoping mechanism 30 to guide along the 1st guide rail 3a, 3b swing.Four guiding devices are same with described 1st embodiment, swinging the corner decentralized configuration of the framework 31 stoping mechanism 30.
Fig. 9 shows the 1st guiding device 60 installed on the left part of framework 31 in the mode corresponding with the 1st guide rail 3a.1st guide rail 3a is formed by the iron as ferromagnetic.1st guiding device 60 possesses pedestal 61 and is supported in the magnet unit 62 of E shape of pedestal 61.
Pedestal 61 is formed by the non-magnetic material that such as aluminium, corrosion-resistant steel or plastics are such, above the left part being fixed on framework 31.In the present embodiment, the Width of elevating road 2 is defined as X-direction, the depth direction of elevating road 2 is defined as Y-direction, the short transverse of elevating road 2 is defined as Z-direction.Thus, as shown in figure 11, side 3e, 3f of the 1st guide rail 3a are the vertical faces orthogonal with Y-direction, and the top edge 3d of the 1st guide rail 3a is the vertical face orthogonal with X-direction.
As shown in figs.10 and 11, magnet unit 62 possesses the 1st to the 4th electromagnet 63a, 63b, 63c, 63d and the 1st and the 2nd permanent magnet 64a, 64b.
1st electromagnet 63a has the 1st magnetic pole 65a in the end that the side 3f of the opposing party with the 1st guide rail 3a is relative.2nd electromagnet 63b has the 2nd magnetic pole 65b in the end that the side 3e of the side with the 1st guide rail 3a is relative.3rd electromagnet 63c and the 4th electromagnet 63d collaborates each other and forms central electromagnet 66.Central authorities' electromagnet 66 extends towards the top edge 3d of the 1st guide rail 3a, and has the 3rd magnetic pole 65c in the end relative with top edge 3d.
And then, be wound with coil 67a, 67b, 67c, 67d respectively at the 1st to the 4th electromagnet 63a, 63b, 63c, 63d.
1st permanent magnet 64a connects the 1st electromagnet 63a and central electromagnet 66.2nd permanent magnet 64b connects the 2nd electromagnet 63b and central electromagnet 66.According to the present embodiment, the homopolarity of the 1st permanent magnet 64a and the 2nd permanent magnet 64b is connected to each other by central electromagnet 66.
In such magnet unit 62, by being clipped in the middle by the sword 3c of the 1st guide rail 3a, the direction of the magnetic line of force of the 1st relative magnetic pole 65a and the 2nd magnetic pole 65b is roughly orthogonal each other with the direction of the magnetic line of force by the 3rd magnetic pole 65c relative with the top edge 3d of sword 3c.And then, between side 3e, 3f and top edge 3d of the 1st to the 3rd magnetic pole 65a, 65b, 65c and the 1st guide rail 3a, there is gap respectively.
Thus, by being controlled the exciting current of the to the 1st to the 4th electromagnet 63a, 63b, 63c, 63d supply by the operation control section 19 of control setup 18, the magnetic force change of the magnet unit 62 for attracting the 1st guide rail 3a can be made.Described in specific as follows.
(1) when mode the to the 1st to the 4th electromagnet 63a, 63b, 63c, 63d of increasing with the magnetic flow of the 1st and the 2nd permanent magnet 64a, 64b supply to give exciting current,
About Y-direction, the magnetic force between the side 3e of the magnetic force between the 1st magnetic pole 65a and the side 3f of the 1st guide rail 3a and the 2nd magnetic pole 65b and the 1st guide rail 3a increases with roughly the same degree.Thus, the increment about the magnetic force of Y-direction is cancelled, and the magnetic force of magnet unit 62 changes hardly.
About X-direction, increased by the magnetic flow between the 3rd magnetic pole 65c and the top edge 3d of the 1st guide rail 3a, therefore, the magnetic force of magnet unit 62 increases.
(2) when mode the to the 1st to the 4th electromagnet 63a, 63b, 63c, 63d of reducing with the magnetic flow of the 1st and the 2nd permanent magnet 64a, 64b supply to give exciting current,
About Y-direction, the magnetic force between the side 3e of the magnetic force between the 1st magnetic pole 65a and the side 3f of the 1st guide rail 3a and the 2nd magnetic pole 65b and the 1st guide rail 3a reduces with roughly the same degree.Thus, the reduction about the magnetic force of Y-direction is cancelled, and the magnetic force of magnet unit 62 changes hardly.
About X-direction, reduced by the magnetic flow between the 3rd magnetic pole 65c and the top edge 3d of the 1st guide rail 3a, therefore, the magnetic force of magnet unit 62 reduces.
(3) when the mode increased with the magnetic flow of the 1st permanent magnet 64a supplies to give exciting current to the 1st and the 3rd electromagnet 63a, 63c and supplies to give exciting current to the 2nd and the 4th electromagnet 63d in the mode of the magnetic flow of the 2nd permanent magnet 64b minimizing
About Y-direction, increase at the 1st magnetic pole 65a side magnetic flow, reduce at the 2nd magnetic pole 65b side magnetic flow.Thus, in 3e side, side and the 3f side, side of the 1st guide rail 3a, the magnetic force of magnet unit 62 produces difference, and magnet unit 62 is attracted by the side 3f to the 1st guide rail 3a.
About X-direction, be cancelled by the variable quantity of the magnetic flow of the 3rd magnetic pole 65c, the magnetic force of magnet unit 62 changes hardly.
(4) when the mode reduced with the magnetic flow of the 1st permanent magnet 64a supplies to give exciting current to the 1st and the 3rd electromagnet 63a, 63c and supplies to give exciting current to the 2nd and the 4th electromagnet 63b, 63d in the mode of the magnetic flow of the 2nd permanent magnet 64b increase, about X-direction, the magnetic force of magnet unit 62 changes hardly, but about Y-direction, the magnetic force of magnet unit 62 produces difference.Thus, magnet unit 62 is attracted by the side 3e to the 1st guide rail 3a conversely.
Above, by being controlled by operation control section 19, to the exciting current of the 1st to the 4th electromagnet 63a, 63b, 63c, 63d supply, magnet unit 62 can be made to change independently relative to the magnetic force in the X-direction of the 1st guide rail 3a and Y-direction.
Thus, when relieving the maintenance swinging and stop mechanism 30 relative to elevating road 2, if make the magnetic force in the X-direction of magnet unit 62 and Y-direction change independently according to the instruction from operation control section 19, then swing and stop mechanism 30 to decline along the 1st guide rail 3a, 3b because of deadweight.
Therefore, same with described 1st embodiment, can mechanism 30 be stoped to retrain the action transversely of main rope 8 in elevating road 2 by the swing declined.
In the 2nd embodiment, swing is made to stop mechanism 30 to decline along the 1st guide rail 3a, 3b by making the magnetic force change of magnet unit 62.Thus, by improving the magnetic force of magnet unit 62 in the midway declined, swing can be made to stop mechanism 30 to stop in the optional position of elevating road 2.
By making swing stop mechanism 30 to stop in the midway of elevating road 2, the development of the swing acting on main rope 8 can be prevented.
On the other hand, when making the magnetic force change of magnet unit 62, although swing can be made to stop mechanism 30 to decline along the 1st guide rail 3a, 3b, swing can not be made to stop mechanism 30 to be risen along the 1st guide rail 3a, 3b.
Thus, in the 2nd embodiment, preferably, stop mechanism 30 to drop to after the position connected above cage 5 in swing, utilize winch 7 to make cage 5 increase, thus stop mechanism 3 to boost towards the top of elevating road 2 by swinging.
Keep swinging stop the position of readiness L1 of mechanism 30 be positioned at than cage 5 the superiors' stop position by the top.Thus, even if cage 5 reaches the superiors' stop position, swing and stop mechanism 30 also possibly cannot arrive position of readiness L1.
As countermeasure, such as can upper beam 13 setting example of cage 5 to swing as accepted stop the framework 31 of mechanism 30 employ hydraulic actuating cylinder or air cylinder boost mechanism.Boosting mechanism reaches the superiors' stop position moment at cage 5 stops mechanism 30 to boost towards position of readiness L1 swing.
After swing stops mechanism 30 to reach position of readiness L1, same with described 1st embodiment, hold-down arm 55a, 55b of stop motion mechnism 54 is made to turn to the 1st position P1 from the 2nd position P2, below the flange part 33 hold-down arm 55a, 55b being hooked on support beam 32a.Thereby, it is possible to make swing stop mechanism 30 to be held in position of readiness L1.
In the 2nd embodiment, stop mechanism 30 to boost position of readiness L1 swing although contemplate via the special mechanism that boosts, be not limited thereto.Such as, also after cage 5 reaches the superiors' stop position, winch 7 can be driven to the direction rolling main rope 8 further, utilize cage 5 to stop mechanism 30 to boost position of readiness L1 swing.
But, because cage 5 has risen above the position of the superiors' stop position, so the slippage of balance weight 6 correspondingly increases.Thus, need to carry out the pit of elevating road 2 being established more deeply wait reply.
And then, as the distortion of the 2nd embodiment, such as, also can be driven by line motor and swing prevention mechanism 30.As one example, can consider in elevating road 2 along the linearly arrangement reaction plate of vertical, and the electromagnet relative with reaction plate is set at the framework 31 swinging prevention mechanism 30.
In addition, in the 2nd embodiment, by making the magnetic force change of magnet unit 62 make swing stop mechanism 30 to decline along the 1st guide rail 3a, 3b, but also can replace magnet unit and use friction element.
The elastic body that friction element possesses the brake shoe part that slidably connects with the sword 3c of the 1st guide rail 3a, 3b and pressed towards the sword 3c of the 1st guide rail 3a, 3b by brake shoe part.By making elastic body change the pressing force of brake shoe part, swing can be made to stop mechanism 30 to decline along the 1st guide rail 3a, 3b, or make swing stop mechanism 30 to stop in the optional position of the midway of elevating road 2.Therefore, it is possible to obtain the effect same with described 2nd embodiment.
Although be illustrated several embodiment of the present utility model, these embodiments propose as an example, are not intended to the scope limiting utility model.The embodiment of these novelties can be implemented in other various modes, can carry out various omission, displacement, change in the scope of purport not departing from utility model.These enforcement sides and distortion thereof are contained in scope and the purport of utility model, and are contained in the utility model described in claims of patent and equivalent scope thereof.
