Fig. 2 represents second example (for example Japanese publication communique: TOHKEMY 2002-338150 communique (1-5 page or leaf, Fig. 1-Fig. 4)) of the electric supply installation of existing lift car.
This elevator comprises: the car 211 of lifting in lifting hoistway 201; One end and this car 211 bonded assembly master ropes 212; Be connected with the other end of this main rope 212 and the counterweight 213 of lifting in lifting hoistway 201; Volume is hung the pulley 221 of main rope 212 pars intermedias; This pulley 221 is provided the electrical motor 222 of propulsive effort; Control the control setup 223 of this electrical motor 222.
This electric supply installation comprises: be arranged on the building side and export the power supply 251,252 of the electric current of assigned frequency; Be connected with this supply unit 251 and in lifting hoistway 201, extend the advance side supply line 251a that is provided with and return side supply line 251b; Be connected with supply unit 252 and with advance side supply line 251a and return side supply line 251b and lifting hoistway 201 in, extend the advance side supply line 252a of setting and return side supply line 252b side by side.
In addition, this electric supply installation also comprises: with these supply line 251a, 251b, 252a, 252b mutually in the face of and be installed in iron core 261a on the car 211 by fabricated section 261d; Be wound on the coil 261b on this iron core 261a; One end and this coil 261b bonded assembly output line 261c; The rectifying circuit 261e that is connected with the other end of this output line 261c and the electro-motive force that coil 261b is induced is carried out rectification; Electro-motive force after the rectification is transformed to the changer of assigned voltage, for example inverter (the 261f of イ Application バ-); The detector 261g that the voltage that utilizes electromagnetic induction to act on to produce among the coil 261b is detected.
Not shownly on the car 211 drive and signal is connected with inverter 261f with the load 214 that power supply etc. constitutes by cage illumination, railway carriage or compartment door.Have identical length with supply unit 251 bonded assembly supply line 251a, 251b with supply unit 252 bonded assembly supply line 252a, 252b, and support by the supporter 215a, the 215b that are separately positioned on lifting hoistway 201 tops and lifting hoistway 201 bottoms.
Even this elevator takes place also can guarantee to the required electric power of car supply work for example Japanese publication communique by the opposing party's supply unit and supply line unusually at side's power supply or supply line: the spy opens 2002-338150 communique (1-5 page or leaf, Fig. 1-Fig. 4).
In order to realize, to supply line that is arranged on the lifting hoistway side and the pickup device (Japanese: the above distance of specified value must be set ピ Star Network ア Star プ) that is arranged on cage side with the method for noncontact mode to the car power supply.Distance between supply line and the pickup device is concerning first example of above-mentioned existing electric supply installation, be equivalent to the distance between conductor 104 and the coil 105, and concerning second example of above-mentioned existing electric supply installation, be equivalent to the distance between supply line 251a, 251b, 252a, 252b and iron core 261a or the coil 261b.
Must the reasons are as follows of distance more than the specified value be set to this part.Car is lateral oscillation sometimes in motion.Lateral oscillation when travelling because of car as if the supply line that is arranged on the lifting hoistway side contacts with the pickup device that is arranged on cage side, will produce big slip sound, and the passenger is felt under the weather.And slip can make supply line and pickup device produce wearing and tearing, also can produce abrasion powder, or significantly descended device lifetime.For this reason, though for car under steam lateral wobble supply line is contacted with pickup device, the distance more than the specified value is set between supply line and pickup device.
Yet, if want from supply line by pickup device when car is powered, the short more power supplying efficiency of in general above-mentioned distance is high more, the long more power supplying efficiency of opposite distance descends.Therefore, as mentioned above, the distance that is provided with between supply line and pickup device more than the specified value in order to prevent to contact can cause the problem that power supplying efficiency descends.If but increase power supplying efficiency and shorten supply line and the distance of pickup device will cause power supply be supply line with pickup device between contact, can bring noise thus and such other problems that weares and teares.
On the other hand, be equipped with various electrical equipments on car, the actuating device of car door need consume bigger electric power in these electrical equipments.The just work when car stops of the actuating device of car door is not worked during car travels.That is to say, when car stops, needing bigger electric power, and do not need big electric power in the process of moving.
As mentioned above, because of the contact noise that causes and the generation in car travels of wearing and tearing of power supply, and can not take place at the car stopping period.If will utilize supply line and the so non-contacting method of supplying power to of pickup device to be applied to elevator the time, can consider noise and wearing and tearing that the car stopping period causes because of the contact of power supply, but need to increase power supplying efficiency.Then the decline of power supplying efficiency does not have great problem under steam, but need prevent noise and wearing and tearing that the contact because of power supply causes.
That is to say that elevator exists following peculiar problem:,, the contact of power supply can take place easily in car travels if shorten the distance between supply line and the pickup device in order to obtain required electric power at the car stopping period.
Therefore, the advantage of situation of the present invention is to provide the elevator of a novelty.
Summary of the invention

Following with reference to description of drawings one embodiment of the invention.
(first embodiment)
The first embodiment of the present invention at first is described.
Fig. 3 is the figure of an example of formation of the elevator of the expression first embodiment of the present invention, is the figure that the expression car is in halted state.Fig. 4 sees the lateral plan that supply line obtains from A-A direction shown in Figure 3.
Among Fig. 3, car 1 combines with an end of rope 2.Counterweight 3 combines with the other end of rope 2.Rope 2 is rolled up on the winch pulley 4 that hangs on the building, and winch pulley 4 is driven by electrical motor 5.Electrical motor 5 combines with control setup 7 by control line 6, by the control signal drive controlling from control device 7.
Be provided with the supply unit 8 of the electric current that flows through preset frequency on building, supply unit 8 is connected with supply line 9.Supply line 9 is configured in above-below direction along the lifting hoistway that car 1 travels, and comprising: the sidepiece 9a that advances, return sidepiece 9b and return portion 9c.
In addition, be provided with building side antenna 12 on building, this antenna 12 utilizes transmission line 13 to be connected with control setup 7.On car 1, be provided with cage side antenna 14.Can send or receive wireless signal mutually between building side antenna 12 and the cage side antenna 14, control setup 7 and car 1 can connect by the biography that they carry out various signals.
Fig. 5 is the enlarged front view of the car 1 of halted state.Fig. 6 sees the electric supply installation 10 resulting birds-eye vieies of the lift-launch shown in Fig. 5 on car 1 top from the top.
As shown in Figure 5, an end of framework 15 combines with the rear portion of pickup device 11.Being provided with screw in the other end of framework 15 is threaded portion 16, and this threaded portion 16 screws with ball-screw 17.Ball-screw 17 combines with servomotor torque constant 18.
Servomotor torque constant 18 combines with pedestal 19, and the bottom of pedestal 19 is fixed on the car 1.In addition, being provided with wheel at the lower surface of framework 15 is guide piece 20a, 20b, and framework 15 can move in the horizontal direction.
On car 1, also be equipped with car control setup 24, it is connected with cage side antenna 14, servomotor torque constant 18, the interior power supply device 22 of car, electric power storing device 23 by transmission line 25a, 25b, 25c, 25d respectively, the biography of carrying out various signals connects, and the action of each equipment is controlled.
Fig. 7 is the amplification stereogram of the relative part of pickup device 11 and the supply line 9 under car 1 halted state.Pickup device 11 comprises: with supply line 9 (9a, 9b) stand facing each other mutually and be E font roughly iron core 26, be wound on the coil 27 on this iron core 26, electric wire 21 is connected with coil 27.
The iron core 26 of pickup device 11 and coil 27 respectively from three directions surround supply line the sidepiece 9a that advances, return sidepiece 9b.Therefore, utilize in the supply line 9 electric current of the assigned frequency that flows in iron core 26, to form field variation efficiently, in coil 27, produce electric power big when travelling thus.
Below the effect of the power supply of the elevator of formation like this is described.At first, the power supply that car 1 is under the halted state describes.
The distance that when stopping, supply line advances sidepiece 9a, return sidepiece 9b and pickup device 11 is short when travelling, when car 1 stops, even iron core 26 or coil 27 and supply line advance sidepiece 9a, return sidepiece 9b and contact also and noise and wearing and tearing can not take place.
The electric power that produces in the coil 27 imports power supply device 22 in the car into by electric wire 21.Power supply device 22 is as required to carrying the various electrical equipment supply capabilities on car 1 in the car, maybe with this electrical power storage in electric power storing device 23.These actions are by 24 controls of car control setup.
When the not shown gangway door to car 1 opens and closes, the not shown actuating device of gangway door carries out work and consumes bigger electric power, but as mentioned above owing in iron core 26, form field variation efficiently, in coil 27, produce electric power big when travelling thus, can not cause power shortage.
Below situation when car 1 begun to travel describe.When beginning to travel, 7 pairs of electrical motors 5 of control setup send driving command, and send " having sent driving command " such signal from building side antenna 12 to cage side antenna 14.The electrical motor 5 that receives driving command makes 4 rotations of winch pulley, thereby car 1 begins to travel.
On the other hand, the signal that sends from building side antenna 12 is received by cage side antenna 14, passes to car control setup 24 by transmission line 25a.The 24 pairs of servomotor torque constants 18 of car control setup that receive signal send driving command, and servomotor torque constant 18 makes ball-screw 17 rotations.
Because the threaded portion 16 and the ball-screw 17 of the framework 15 of electric supply installation 10 screw, so along with the rotation of ball-screw 17, framework 15 reaches the pickup device 11 that combines with the one end and moves to the direction of leaving supply line 9 under the support of guide piece 20a, 20b.That is to say that car control setup 24, servomotor torque constant 18 and ball-screw 17 play the effect of the distance change means of distance between the coil 27 that can change pickup device 11 and the supply line 9.
Fig. 8 is the enlarged front view that mobile end, the car 1 of pickup device 11 is in the car 1 under the motoring condition.Fig. 9 is the lift-launch shown in Figure 8 seen from a top birds-eye view at the electric supply installation 10 on car 1 top.
As Fig. 8 and shown in Figure 9, under the state that car 1 is travelling, supply line advance sidepiece 9a, return the outside that sidepiece 9b is in the zone that is surrounded by iron core 26 and coil 27.
Therefore, supply line advance sidepiece 9a, return distance between sidepiece 9b and the pickup device 11 than stopping duration, even therefore car 1 travel and lateral wobble can not make yet iron core 26 and coil 27 and supply line advance sidepiece 9a, return sidepiece 9b and contact, noise and wearing and tearing can not take place.
Since so make supply line advance sidepiece 9a, return distance between sidepiece 9b and the pickup device 11 than stopping duration, the field variation ratio that forms in the iron core 26 is little when stopping, correspondingly the electric power that produces in coil 27 is also little when stopping.
Yet, when car 1 travels,, also need not start the actuating device of the gangway door that consumes big electric power owing to do not need to open and close the gangway door.Therefore, even the electric power that produces is less, can not cause the required power shortage of car 1 yet.
Situation when below car 1 arrival purpose floor being stopped describes.
When car was desired to stop to travel near the purpose floor, control setup 7 sent halt instruction to electrical motor 5, and sends " having sent halt instruction " such signal from building side antenna 12 to cage side antenna 14.The electrical motor 5 that receives halt instruction reduces the rotative speed of winch pulley 4, and car 1 is stopped on the purpose floor.
On the other hand, the signal that sends from building side antenna 12 is received by cage side antenna 14, passes to car control setup 24 by transmission line 25a.The 24 pairs of servomotor torque constants 18 of car control setup that receive signal send driving command, servomotor torque constant 18 make ball-screw 17 towards and opposite direction rotation when beginning to travel.
Because the threaded portion 16 and the ball-screw 17 of the framework 15 of electric supply installation 10 screw, so along with the rotation of ball-screw 17, framework 15 reaches the pickup device 11 that combines with the one end and moves to the direction near supply line 9 under the support of guide piece 20a, 20b.
The mobile end of pickup device 11, car 1 are under the halted state, and the position relation of pickup device 11 and supply line 9 returns to Fig. 5 and car shown in Figure 6 begins the preceding state that travels.
Take place to have a power failure in below car 1 being travelled and can't provide situation to describe from the electric current of supply unit 8 and supply line 9.At this moment, owing to can not power to electrical motor 5 and winch pulley 4, thereby car 1 stops.Yet, owing to be equipped with electric power storing device 23 on the car 1, thereby identical action can utilize the electric power that is stored in this device to carry out stopping with car 1 arrival purpose floor the time.
Therefore, cause car 1 to stop even car 1 takes place to have a power failure under steam, pickup device 11 is moved, car 1 can return to the state of Fig. 5 and Fig. 6.Finish when having a power failure, behind supply unit 8 and supply line 9 supplying electric currents, electric supply installation 10 can be efficiently to car 1 power supply again.
As mentioned above, distance between supply line 9 and the pickup device 11 is shorter at the car stopping period, longer under steam, thereby can be when car 1 needs big electric power efficiently to the car power supply, even and in motion car 1 lateral wobble also can prevent noise and the wearing and tearing that cause that contact between supply line 9 and the pickup device 11.
In addition, it is shorter that the distance between supply line 9 and the pickup device 11 also can be arranged in the slow time distance of car speed, and distance is longer when speed is fast.
In addition, also can utilize above-mentioned formation that the distance between supply line 9 and the pickup device 11 and the action of the gangway door of car 1 are changed explicitly.That is to say, make the distance between supply line 9 and the pickup device 11 shorter under the big situation of the possibility of door action, longer under the little situation of the possibility of door action.
In addition, also can utilize above-mentioned formation that the working condition of the distance between supply line 9 and the pickup device 11 with car 1 interior equipment changed explicitly.That is to say, make the devices consume electric power of distance in car between supply line 9 and the pickup device 11 shorter for a long time, it is longer after a little while to consume electric power.

Below the second embodiment of the present invention is described.The elevator of present embodiment is put on identical symbol to the formation identical with Fig. 3 in constituting, and omits repeat specification.
Figure 10 is the figure of an example constituting of the elevator of expression second embodiment of the invention.Figure 11 sees the resulting lateral plan of supply line from B-B direction shown in Figure 10.
In the present embodiment, replace the car 1 of first embodiment with car 51 (51a, 51b, 51c).
Figure 10 represented respectively topmost stop car 51a that the floor place stopping, at car 51c, the car 51b that between this two place, is travelling that the floor place is stopping that stopping of foot.
Figure 12 is the enlarged front view of car 51a under the halted state.Figure 13 is the lift-launch shown in Figure 12 seen from a top birds-eye view at the electric supply installation 53 on car 51a top.
The supply line 9 of supply line 52 replacements first embodiment is connected with the supply unit 8 on being arranged on building.Supply line 52 is configured in above-below direction along the lifting hoistway that car 51 travels, it is crooked that this supply line 52 is arranged to a part, thereby when car 51 was stopping floor and is in halted state, supply line 52 was near these car 51 sides, and supply line 52 leaves this car 51 when car 51 is in motoring condition.
The electric supply installation 10 that replaces first embodiment, electric supply installation 53 carry on car 51, are installed in the top of electric supply installation 53 as the pickup device 11 of the part of electric supply installation 53.The detailed structure of pickup device 11 is identical with the explanation that first embodiment is done, and puts on identical symbol.But, the rear portion of pickup device 11 is fixed on the car 51, directly combines with pedestal 54 as the part of electric supply installation 53.
Identical with first embodiment, electric wire 21 is drawn from pickup device 11, and is connected with power supply device 22 in the car.Power supply device 22 is connected with electric power storing device 23 in the car.The various electrical equipments of lift-launchs such as lighting fixture on car 51 in the car in 22 pairs of car door actuating devices of power supply device and the car are powered.
On car 51, also be equipped with car control setup 24, it is connected with cage side antenna 14, the interior power supply device 22 of car, electric power storing device 23 by transmission line 25a, 25b, 25c, 25d respectively, the biography of carrying out various signals connects, and the action of each equipment is controlled.
As shown in Figure 5, in first embodiment, need servomotor torque constant 18, with this servomotor torque constant 18 bonded assembly transmission line 25b, but servomotor torque constant 18 is not set among second embodiment, thereby does not need this transmission line.Owing to do not need servomotor torque constant 18 among this second embodiment, thereby just do not need ball-screw 17 and the framework 15 of first embodiment yet.
Below the effect of the power supply of the elevator of formation like this is described.
Stopping among the car 51a that floor is in halted state of topmost, the iron core 26 of pickup device 11 and coil 27 respectively from three directions surround supply line the sidepiece 52a that advances, return sidepiece 52b.Therefore, utilize in the supply line 52 electric current of the assigned frequency that flows in iron core 26, to form field variation efficiently, in coil 27, produce electric power big when travelling thus.
The distance that supply line advances sidepiece 52a, return sidepiece 52b and pickup device 11 is short when car 51 stops that time, ratio travelled, because car 51 is in halted state, even thereby supply line advance sidepiece 52a, return sidepiece 52b and contact also with iron core 26 or coil 27 and noise and wearing and tearing can not take place.
The electric power that produces in the coil 27 imports power supply device 22 in the car into by electric wire 21.Power supply device 22 is as required to carrying the various electrical equipment supply capabilities on car 51 in the car, maybe with this electrical power storage in electric power storing device 23.These actions are by 24 controls of car control setup.
When the not shown gangway door to car 51 opens and closes, the actuating device of gangway door carries out work and consumes bigger electric power, but as mentioned above owing in iron core 26, form field variation efficiently, in coil 27, produce electric power big when travelling thus, can not cause power shortage.
51 courts descend the floor begin column to sail most at car, when the position of car 51 moves to the position of car 51b shown in Figure 10, supply line 52 is configured to leave car 51, thus supply line advance sidepiece 52a, return the outside that sidepiece 52b is in the zone that is surrounded by iron core 26 and coil 27.
Therefore, the distance that supply line advances sidepiece 52a, return between sidepiece 52b and the pickup device 11 is elongated, even therefore car 51 travel and lateral wobble can not make yet iron core 26 and coil 27 and supply line advance sidepiece 52a, return sidepiece 52b and contact, noise and wearing and tearing can not take place.
Supply line advances sidepiece 52a, the distance returned between sidepiece 52b and the pickup device 11 is elongated when stopping owing to so making, and the field variation ratio that forms in the iron core 26 is little when stopping, and correspondingly the electric power that produces in coil 27 is also little when stopping.
Yet, when car 51 travels,, also need not start the actuating device of the gangway door that consumes big electric power owing to do not need to open and close the gangway door.Therefore, even the electric power that produces is less, can not cause the required power shortage of car 51 yet.
The purpose floor that arrives foot when car 51 stops, when the position of car 51 moves to the position of car 51c shown in Figure 10, supply line 52 is configured near car 51 sides, and supply line 52 returns to the state of car shown in Figure 10 51 when topmost stops with the position relation of pickup device 11.
As mentioned above, in the elevator of the second embodiment of the present invention, it is crooked that supply line is arranged to a part, thereby the distance between supply line and the pickup device 11 is shorter when car is positioned at stop position, and the distance between supply line and the pickup device 11 is longer when car is positioned at traveling-position, thereby it is identical with first embodiment, can be when car needs big electric power efficiently to the car power supply, even and in motion the car lateral wobble also can prevent noise and the wearing and tearing that cause that contact between supply line and the pickup device 11.
