Abstract

The present invention provides an elevator device, wherein a top part of a falling prevention plate (32) at the lower end of a transporting cage (31) which operates in a lifting channel (35) is set to convex-shaped, so the cross section in a horizontal direction has different shapes relatively to the operation direction of the transporting cage (31). Thus when the transporting cage (31) gets next to a hall threshold (36), the air current is not blocked by the top part and spreads to the circumference, thereby restricting the rapid air current which flows to a front surface of the cage for reducing the aerodynamic noise.

Description

Lift appliance

Technical field

Embodiments of the present invention relate to the lift appliance that can reduce aerodynamic force noise when advancing.

Background technology

Along with the high stratification in building, also more and more higher for requirement as the elevator of the vehicle longitudinally.One of them is exactly the high speed of elevator.Again, according to building standard method, the command speed of elevator is defined as " maximum speed when car rises " under the effect of load-carrying.If elevator is classified according to speed, then the regulation command speed is that the elevator of per minute below 45 meters is " low speed ", per minute is that 60～105 meters elevator is " middling speed ", and per minute is that the elevator more than 120 meters is " at a high speed ", and per minute is that the elevator more than 360 meters is " hyper-speed ".

Along with the command speed of elevator arrives more than 400 meters/minute, owing to the air-flow around the cage produces the aerodynamic force noise ride comfort sense of elevator has been produced influence (referring to for example, Japan's mechanics meeting collection of thesis (B volume), No. 564 (1993-8) of 59 volumes, paper No.92-1876).

In order to reduce the aerodynamic force noise of such super high speed elevator, the installation of the rectification campaign lid that is disclosed by for example Japanese kokai publication hei 4-333486 communique is specialized and can be obtained certain effect.

But, for the elevator of in narrow hoist trunk, advancing, corresponding to the lifting floor, in hoist trunk, have narrow such as entrance hall threshold, therefore whenever by this narrow the time, can produce local aerodynamic force noise (バ Off sound), to the passenger in the car just much less, even concerning the passenger who waits for elevator at the floor that passes through, also be very big sound pollution source, the problem that causes human discomfort is arranged still.

Therefore, further high speed for corresponding elevator, developed in the rectification campaign and (for example covered installation rectification campaign bumper/spoiler, TOHKEMY 2005-162496 communique), it (for example is used for the most high-revolving elevator in the world, the most high-revolving 1010 meters/minute elevators in the world, Toshiba's editorial (レ PVC ユ one) vol.57, No.6 (2002)) obtained certain effect.

Summary of the invention

Invent problem to be solved

Along with accessibility in recent years,, require the gap between lifting floor and the car further to reduce in order to make wheelchair and perambulator can not step on sky.Therefore, along with the gap of hoist trunk in-to-in narrow reduces further, even the low～express elevator that did not have noise problem in the past also can produce local aerodynamic force noise (バ Off sound) when the narrow by hoist trunk.

In low～high-revolving elevator,, be equipped with and be commonly referred to as falling of " baffle plate " and prevent plate in the bottom of cage.This falls and prevents that plate from being to be used to prevent the parts of object from falling between the entrance hall threshold of hall and the space between the car door, and it extends the length of regulation towards descent direction from edge of car door.

For low～express elevator with such shape, aerodynamic force noise when observing it descend when measuring the position of cage found that when the described top end part that prevents plate that falls can produce very big noise during near the crevice in the hoist trunk.Again, too, the end of cage also produces very big noise during near the crevice in the hoist trunk when rising.

But, for such aerodynamic force noise, not having effectively corresponding scheme now, can only improve passage, for example all stick plate at all travel paths and carry out complanation etc. in order to remove crevice.

Again, usually, average out, make elevator advance with the balance block (weight equalizer) of weight such as cage body.Therefore when near intermediate floor, balance block and cage body miss at a high speed, and be the same by the situation of narrow with cage, also can produce bigger noise around the cage.

Thereby, wish to obtain a kind of lift appliance of the aerodynamic force noise that produces can reduce cage and advance the time.

The specific embodiment

At first, before explanation embodiment, be example with low～express elevator, the generation mechanism of aerodynamic force noise when the detailed description elevator is advanced.

In low～express elevator, the hall side in the cage bottom of box-formed shape is equipped with and is called falling of " baffle plate " and prevents plate, and this falls and prevents plate, extends certain length from the edge of car door towards descent direction.

For low～express elevator with such shape, on one side the instrumentation car position observe the noise that produces in the traveling process on one side the result as shown in Figure 1.

In Fig. 1, transverse axis is represented the time, and the longitudinal axis is represented noise level.If make car descend, the moment falling the narrow such as the close entrance hall of top end part threshold that prevent plate, produce aerodynamic force noise (shown in the arrow among the figure) thereby produce big pressure variation with the speed of regulation.

The result who flows of the air of car periphery as shown in Figure 3 and Figure 4 when advancing by numerical value fluid analysis (CFD:Computational Fluid Dynamics) research elevator here.

Fig. 3 and Fig. 4 be by the numerical value fluid analysis to the cage of elevator during by the entrance hall threshold in the hoist trunk air-flow around the car investigate resulting result, Fig. 3 demonstrate soon by the time state, Fig. 4 shows the state that is passing through.Again, 31 among the figure represents cage, and 32 expressions fall and prevent plate (baffle plate), 36 expression entrance hall thresholds.

When car 31 descended, when falling the narrow such as the close entrance hall of top ends threshold 36 that prevent plate 32, falling the top ends office air-flow that prevents plate 32 was hindered, thereby produces the generation that big pressure variation causes the aerodynamic force noise.

Particularly, peel off bubble, find out easily that according to the numerical value fluid analysis this has encouraged the change of pressure owing to fall the top end part existence that prevents plate 32.

That is,, encouraged barrier effect because this bubble of peeling off that falls the top end part generation that prevents plate 32 makes that the loss of pressure in gap increases between cage 31 and the entrance hall threshold 36.The result prevents that from falling plate 32 both sides from generating vertical eddy current 2 rapidly as shown in Figure 4, because the air-flow that should vertical eddy current 2 enters from top ends concentrates on the middle body in the front of cage 31, these become contracted flow speedup stream 1 and quicken.According to Bernoulli's theorem, these vertical eddy current 2 and contracted flow speedup stream 1 make the pressure in car front descend rapidly, produce very large pressure variation.

On the other hand, the aerodynamic force noise that produces when elevator or automobile are advanced is because the unconventional motion of the eddy current that exists in the air-flow of upsetting because of advancing produces the increase rapidly along with the increase of gait of march.Such aerodynamic force noise can be that the wave equation (Lighthill equation) that the equational distortion of Navier-Stokes obtains is tried to achieve by the fundamental equation of fluid.This wave equation is shown in (1) formula.

Shown in first expression in (2) formula, being accompanied by the aerodynamic force noise of volume change of the air-flows such as stream or suction current of gushing out and the biquadratic of speed and producing pro rata.

Again, second expression of above-mentioned (2) formula, noise that is changed by amount of exercise the automobile during as high-speed travel or the noise of the Shinkansen and produce and six powers of speed are proportional, the noise that the 3rd expression produces because of the unconventional motion of upsetting stream as the ejection sound of injection engine and the proportional generation of eight power of speed.

Here, change the gait of march of elevator, and meanwhile the instrumentation narrow by the time the aerodynamic force noise, as shown in Figure 2, the biquadratic of aerodynamic force noise and gait of march becomes big pro rata as can be known.This expression, the aerodynamic force noise during by narrow is the volume change that rapid unexpected suction air-flow causes air-flow when preventing close entrance hall, plate 32 tops threshold 36 because of falling of cage 31 as shown in Figure 4 (, pressure variation) and producing.Hence one can see that, and for lowering the aerodynamic force noise, the change that relaxes pressure is an actv..

Below, the concrete grammar that reduces the aerodynamic force noise is elaborated.

(first embodiment)

Fig. 5 A, Fig. 5 B are the scheme drawings of the lift appliance structure that shows that first embodiment relates to, and Fig. 5 A is a scheme drawing of observing the cage of advancing from the side in hoist trunk, and Fig. 5 B is a front view of observing this cage from the A direction.

The lift appliance of present embodiment mainly has the cage 31 of the box-formed shape that is used for slower elevators.This cage 31 is done lifting action by cable 34 in hoist trunk 35 under the driving of the winch that figure does not show.

Again, the hall side of the bottom of this cage 31 is equipped with and is commonly referred to as falling of " baffle plate " and prevents plate 32.This falls and prevents that plate 32 from being the tabular parts that are used to prevent that object from falling from the entrance hall threshold 36 and the gap between the car door 32 of hall, and its edge from car door 32 extends with certain length towards descent direction.

On the other hand, in hoist trunk 35, the hall of each layer all is provided with entrance hall threshold 36, and the top of this entrance hall threshold 36 is provided with folding Room door 38 freely.The front of cage 31 is provided with folding car door 33 freely, its when cage 31 when each layer hall stops, engage with hall Room door 38 and to carry out opening and closing movement.The narrow that 37 expressions are formed by the entrance hall threshold 36 in the hoist trunk 35 among the figure.

In such structure, when car riding 31 descends, the bottom of cage 31 and when falling the top ends that prevents plate 32 by the narrow in the hoist trunk 35 37, produce local aerodynamic force noise, thereby the passenger that the passenger in the cage 31 and hall wait is caused sense of discomfort.

Therefore, in the present embodiment, prevent that by the shape that prevents plate 32 that falls that is arranged on cage 31 bottoms being improved, when advancing, will being fallen plate 32 is used as " rectification campaign plate " and reduces the aerodynamic force noise.

Specifically, shown in Fig. 5 B, form protuberance 32a towards the decline direction near falling the top ends central authorities that prevent plate 32.By forming such shape, when cage 31 descended, when falling the narrow 37 such as the close entrance hall of top ends threshold 36 that prevent plate 32, the interception at this top ends place obtained relaxing, and can suppress air-flow and flow into the car front rapidly.

Its situation is by Fig. 6 and shown in Figure 7.

The resulting result of air-flow in the car front when Fig. 6 and Fig. 7 show by numerical value fluid analysis investigation cage 31 by the entrance hall threshold 36 in the hoist trunk 35, Fig. 6 represent soon by the time state, state when promptly falling the top end part that prevents plate 32 near entrance hall threshold 36, Fig. 7 is presented at by the state in the process, the state when promptly falling the integral body that prevents plate 32 by entrance hall threshold 36.

Herein, when falling the top ends that prevents plate 32 and being set to convex, cage 31 is during near entrance hall threshold 36, and the air-flow of this moment can not fallen the top ends that prevents plate 32 and temporarily tackle, but around being diffused into.Thereby, can suppress the air-flow that (face relative with hall) flows into rapidly towards the car front, with relax along with and the pressure variation that comes.

Fig. 8 is the scheme drawing that shows in the hoist trunk measurement result of the pressure variation on the wall of the entrance hall threshold 36 in 35.Hours underway 0 expression falls the top ends that prevents plate 32 moment near entrance hall threshold 36.Again, dotted line is represented the feature of existing shape, and solid line is represented converx characteristic.

The inventor discovers that the pressure of front and back increases rapidly in the time 0, and the generation of the phenomenon of the pressure decay rapidly of Chan Shenging and the aerodynamic force noise during by narrow has very strong contact thereupon.Thereby,, can estimate the reduction effect of aerodynamic force noise by studying the size of this pressure variation.

With falling the top ends that prevents plate 32 is that the situation of smooth existing shape is compared, and has under the converx situation, falls the pressure variation of top ends during near entrance hall threshold 36 that prevents plate 32 and obtains relaxing.Thus, the aerodynamic force noise that causes owing to pressure variation as can be known is lowered.

Like this, falling of cage 31 prevents that plate 32 is used as rectification campaign plate, because its top ends is a convex, towards the air-flow rapidly in car front, relaxes pressure variation in the time of can suppressing by narrow.Like this, can not adopt the machine that for example cage 31 is provided with the special use that suppresses pressure variation, or the hoist trunk structure is transformed bothersome like this countermeasure, just can reduce the aerodynamic force noise when advancing.

In addition, the outstanding width etc. that is formed at the protuberance 32a that falls the top ends that prevents plate 32 is redefined for only value by test or numerical analysis etc., falls the suffered air-flow of top ends that prevents plate 32 so that can be diffused in efficiently.

Again, in above-mentioned first embodiment, show and make converx example falling the top ends that prevents plate 32, but as long as it is shaped as the direct of travel with respect to cage 31, the sectional area part of horizontal direction is different, even other shapes also can obtain same effect.

Even if fall the structure that the top ends that prevents plate 32 forms a plurality of excision 32h of portion, also can be as above-mentioned first embodiment, the air-flow when making near entrance hall threshold 36 is falling the top ends place diffusion that prevents plate 32.Like this, can suppress, and can effectively relax the pressure variation of this moment, reduce the aerodynamic force noise towards the positive air-flow rapidly that flows into of car.

(variation 8)

Figure 16 be show above-mentioned first embodiment variation 8 fall the top ends alteration of form that prevents plate the time the scheme drawing of Facad structure of cage.

In the variation 8 of Figure 16, shown falling the example that the top ends that prevents plate 32 is formed with a plurality of aperture 32i of portion.The number of the 32i of these aperture portions and size etc. by experiment or numerical analysis be designed to only value in advance, make that falling the air-flow that the top ends that prevents plate 32 is subjected to can effectively spread.

Owing to form a plurality of aperture 32i of portion falling the top ends that prevents plate 32, the air communication when making near entrance hall threshold 36 is crossed each 32i of aperture portion towards other directions diffusions.Like this, can suppress, and can effectively relax the pressure variation of this moment, reduce the aerodynamic force noise towards the positive air-flow rapidly that flows into of car.

(variation 9)

Figure 17 be show above-mentioned first embodiment variation 9 fall the top ends alteration of form that prevents plate the time the scheme drawing of Facad structure of cage.

In the variation 9 of Figure 17, shown near the setting protuberance 32a identical middle body that falls the top ends that prevents plate 32, and on this protuberance 32a, formed the example of the aperture 32j of portion with above-mentioned first embodiment.The size of the projecting degree of protuberance 32a and the 32j of aperture portion etc. by experiment or numerical analysis be designed to only value in advance, make that falling the air-flow that the top ends that prevents plate 32 is subjected to can effectively spread.

Even if falling the structure that the top ends that prevents plate 32 forms the protuberance 32a with the 32j of aperture portion, also can be identical with above-mentioned first embodiment, the air-flow when making near entrance hall threshold 36 is falling the top ends place diffusion that prevents plate 32.And, owing on protuberance 32a, formed the 32j of aperture portion, fall the air-flow that the top ends that prevents plate 32 is blocked can be by the 32j of aperture portion towards other directions diffusions.Like this, can further suppress, and can effectively relax the pressure variation of this moment, reduce the aerodynamic force noise towards the positive air-flow rapidly that flows into of car.

Again, in above-mentioned first embodiment, suppose that standard is provided with and be called as the cage 31 that falling of " baffle plate " prevents plate 32, prevent that to this is fallen the situation that plate 32 is used as " rectification campaign plate " is illustrated.But, do not fall the cage that prevents plate if do not have, also can obtain above-mentioned same noise and reduce effect by any plate-shaped member conduct " rectification campaign plate " with above-mentioned different shape is installed in the hall side of cage bottom.

(second embodiment)

Then, second embodiment is described.

In a second embodiment, formation not only when car descends, also can reduce the structure of aerodynamic force noise when rising.

Figure 18 A, Figure 18 B shows such structure.

Figure 18 A, Figure 18 B are the scheme drawings of the structure of the lift appliance that relates to of second embodiment, and Figure 18 A is a scheme drawing of observing the cage of advancing from the side in hoist trunk, and Figure 18 B is a front view of observing this cage from the A direction.Again, with Fig. 5 A of described first embodiment, the part additional phase symbol together that Fig. 5 B is identical omits its explanation.

The places different with first embodiment are, are provided with and are arranged on the tabular rectification campaign plate 39 that falling of bottom prevents plate 32 pairings at the edge of the hall side of the upper end of the cage 31 of box-formed shape.Edge from the hall side extends certain-length to ascent direction to this rectification campaign plate 39 in the upper end of cage 31.

Herein, in a second embodiment, the central vicinity of the top ends of this rectification campaign plate 39 is formed with protuberance 39a towards ascent direction.This protuberance 39a prevents on the plate 32 that with falling the protuberance 32a that forms is identical, be suppressed in the time of playing upper end at cage 31 by the narrow 37 such as entrance hall threshold 36 hoist trunk 35 in rectification campaign plate 39 the top ends generation peel off stream.

By such structure, even when cage 31 rises because and identical reason when descending, the air-flow during near entrance hall threshold 36 can spread at the top ends place of rectification campaign plate 39, the air-flow that inhibition flows into rapidly towards the car front relaxes the pressure variation of this moment and reduces the aerodynamic force noise.

In general, compare pressure variation when rising during decline and become big again.This be because, because the structure of building, air flow from top to bottom in the hoist trunk 35 usually, if cage 31 descends, the power of the air-flow that is subjected in the top ends of narrow 37 place's cages 31 such as entrance hall threshold 36 is bigger.

Again, in above-mentioned second embodiment, the top ends of rectification campaign plate 39 forms convex, if still the shape of described rectification campaign plate 39 is with respect to the direct of travel of cage 31, the sectional area of its horizontal direction part is different, and other shapes also can obtain same effect.

Below, the variation of above-mentioned second embodiment is described.

(variation)

Figure 19 is the scheme drawing of the Facad structure of the cage when showing the top ends alteration of form of rectification campaign plate in the variation of above-mentioned second embodiment.

In the variation of Figure 19, the top ends of rectification campaign plate 39 tilts towards opposite side from a side of cage 31.Again, the angle of inclination of this rake 39a etc. by experiment or numerical analysis be designed to only value in advance, make that falling the air-flow that the top ends that prevents plate 32 is subjected to can effectively spread.

Like this, even if the top ends of rectification campaign plate 39 is also identical with described first embodiment to the structure of the lopsidedness of cage 31, air-flow is in the diffusion of the top ends place of rectification campaign plate 39 near entrance hall threshold 36.But, because the air-flow that the top ends of rectification campaign plate 39 is subjected to can suppress the air-flow rapidly towards the car front further towards the side diffusion of cage 31, to relax pressure variation at this moment and to reduce the aerodynamic force noise.

Again, here, though show the top ends bevelled situation that makes rectification campaign plate 39, also applicable Fig. 9～13, the shown shape in Figure 15～17.Further, also can and constitute at the upper end of cage 31 side and bottom side combination different shape.

(the 3rd embodiment)

Then, the 3rd embodiment is described.

In the 3rd embodiment, except the structure of above-mentioned second embodiment, the bigger problem of space noise when descending by narrow in order to solve is provided with air-stream generating device in the bottom of cage.

Figure 20 A, Figure 20 B has shown such structure.

Figure 20 A, Figure 20 B are the scheme drawings of the structure of the lift appliance that shows that the 3rd embodiment relates to, and Figure 20 A is the cage side observation figure that advances in the hoist trunk, and Figure 20 B is a front view of observing this cage from the A direction.Again, with Figure 18 A of described second embodiment, the additional same-sign of the part that Figure 18 B is identical, and omit its explanation.

Identical with described second embodiment, the bottom of cage 31 is installed converx the falling with " rectification campaign plate " function and is prevented plate 32, again, the converx rectification campaign plate 39 that prevents plate 32 pairings is set and falls in the upper end.Like this, when cage 31 descends and when rising, flow into and to be inhibited, and reduce the aerodynamic force noise that the pressure variation of this moment brings towards the air-flow rapidly in car front.

Here, in the 3rd embodiment, further, the falling of bottom of cage 31 prevented that plate 32 is provided with air-stream generating device 10a, 10b.This air- stream generating device 10a, 10b utilize discharge plasma to cause stream 25 towards direction (the being ascent direction) generation of regulation herein.

Again, for the air-stream generating device that utilizes plasma discharging, open 2007-317656 communique of Japanese Patent and patent disclosure 2008-1354 communique etc. are open, are not elaborated at this.

This air- stream generating device 10a, 10b are to be the modular construction of basal disc with insulators such as potteries, can module section are fixed in to fall simply by screw or adhesive agent etc. to prevent on the plate 32.

Again, this air- stream generating device 10a, 10b is driven by the moment of actuating device in regulation when cage 31 is advanced.The moment of regulation, specifically, when the bottom of cage 31 is by entrance hall threshold 36 when being cage 31 declines.

Promptly, fall the air-stream generating device 10a that prevents setting on the plate 32,10b falls the top ends that prevents plate 32 and is driven during by entrance hall threshold 36 when cage 31 descends, be that ascent direction produces and causes stream 25 to the direction opposite with the direct of travel of cage 31.

Figure 21 is the block diagram of structure that shows the control system of air-stream generating device.

Actuating device 11 is arranged on the cage 31, has to be used to provide air-stream generating device 10a the battery of the driving required electric power of 10b.This actuating device 11 offers air-stream generating device 10a based on the drive signal of control setup 12 outputs with electric power, and 10b is to drive.

Again, control setup 12 is arranged in the Machine Room etc. in building.This control setup 12 is made of the computing machine that is equipped with CPU, ROM, RAM etc., and the startup by specific program moves control to elevator integral body, the promoting the circulation of qi flow generating apparatus 10a that goes forward side by side, the drive controlling of 10b.Again, buttock line or the dedicated radio link of the actuating device 11 on control setup 21 and the cage 31 by scheming not show.

Device for detection of position of car body 13 detects the position of the cage 31 of advancing in the hoist trunk 35 in real time based on the impulse singla of the pulse coder output of synchronously not showing from figure with the rotation of winch.

In such structure, when cage 31 descends, control setup 12 prevents the moment driving air-stream generating device 10a of the top ends of plate 32 near the narrow 37 of entrance hall threshold 36 grades, 10b by the position of device for detection of position of car body 13 detection cages 31 falling of cage 31.Thus, from air- stream generating device 10a, 10b sprays to ascent direction and causes stream 25.

Cause stream 25 by this, the stream of peeling off that falls the top ends that prevents plate 32 is suppressed, and the generation of vertical eddy current is also weakened.Thereby the air-flow sinuous flow that can produce to by narrow the time carries out rectification, and more effectively suppresses pressure variation to reduce the aerodynamic force noise.

Again, adopt the air-flow control of plasma discharging, also begin to be studied in the utilization of field of aircraft etc.But, be generally used for reducing the air impedance in moving, in general, plasma is generally the ON state.

Relative, different with moving body such as aerocraft in lift appliance, cage 31 moves in hoist trunk 35 such space high speeds that are restricted, and entrance hall threshold 36 places of each layer produce aerodynamic noise owing to rapidly pressure variation in its way.Therefore,, just need detect the position of car in hoist trunk, and make that in the moment of regulation plasma is the distinctive drive controlling of the such elevator of ON in order to reduce such aerodynamic force noise.

To carry out ON/OFF control be recommendable from the viewpoint of saving in energy to the article on plasma body when further, advancing.

Again, plasma causes that the generation of stream needs the electric power of number W.Therefore, can easily deal with from the driving electric of cage 31.Actuating device 11 can be miniaturization, can be arranged on easily in the cage 31.

Like this, falling the top ends that prevents plate 32 is convex, also has air-stream generating device 10a further, 10b, and like this, the noise that can improve when descending lowers effect, makes that the environment of advancing of elevator is more comfortable.

Again, Figure 20 A in the example of Figure 20 B, has shown that the bottom of cage 31 and the top ends of upper end all form converx situation, but also can form the shape shown in Fig. 9～17.

Further, the upper end side of cage 31 and bottom side, different shape also capable of being combined constitutes.Again, air-stream generating device 10a, the setting of 10b and number also are not limited to Figure 20 A, shown in Figure 20 B, can carry out suitable variation.

(the 4th embodiment)

Then the 4th embodiment is described.

In the 4th embodiment, when eliminating the decline of cage and the aerodynamic force noise problem in when rising, the air-stream generating device that all is provided with in the bottom and the upper end of cage.

Figure 22 A, Figure 22 B has shown such structure.

Figure 22 A, Figure 22 B are the scheme drawings of the structure of the lift appliance that shows that the 4th embodiment relates to, and Figure 22 A is the side observation figure of the cage of advancing in the hoist trunk, and Figure 22 B is a front view of observing this cage from the A direction.Again, with Figure 18 A of described second embodiment, the additional same-sign of the part that Figure 18 B is identical, and omit its explanation.

Identical with described second embodiment, the bottom of cage 31 is installed converx the falling with " rectification campaign plate " function and is prevented plate 32, again, the converx rectification campaign plate 39 that prevents plate 32 pairings is set and falls in the upper end.Like this, when cage 31 descends and when rising, flow into and to be inhibited, and reduce the aerodynamic force noise that the pressure variation of this moment brings towards the air-flow rapidly in car front.

Here, in the 4th embodiment, further, the falling of bottom of cage 31 prevented that plate 32 is provided with air-stream generating device 10a, 10b.While also is provided with same air- stream generating device 10c, 10d on the rectification campaign plate 39 of the upper end of cage 31.

These air- stream generating devices 10a, 10b, 10c, 10d utilize plasma discharging to cause stream 25 towards the direction generation of regulation.Here, air- stream generating device 10a, 10b produce towards the rising direction and cause stream 25, and air- stream generating device 10c, 10d produce towards the decline direction and cause stream.

Again, these air- stream generating devices 10a, 10b, 10c, 10d is driven by the moment of actuating device shown in Figure 21 12 in regulation when cage 31 is advanced.The moment of regulation specifically, is the moment of the bottom of cage 31 cage 31 when descending by entrance hall threshold 36, and the upper end of cage 31 cage 31 when rising is by the moment of entrance hall threshold 36.

Figure 23 shows the diagram of circuit of the drive controlling of air-stream generating device when cage is advanced.

Cage 31 is with the speed (step S11 is for being) when ascent direction moves of regulation.Control setup 12 detects the position (step S12) of cage 31 based on the position signal of device for detection of position of car body 13 outputs, when the top ends of the rectification campaign plate 39 of the upper end that is arranged at cage 31 is about to by entrance hall threshold 36 (step S13 is for being), drive air- stream generating device 10c, 10d specified time (step S14) by actuating device 11.Again, described specified time is the time till the top ends of cage 31 is passed through entrance hall threshold 36, decides though need look the speed of cage 31, probably about 0.3～0.5 second.

On the other hand, at cage 31 with specified speed (step S11 for not) under the situation that descent direction moves, control setup 12, detect the position (step S16) of cage 31 based on position signal from device for detection of position of car body 13 outputs, when falling of the bottom that is installed in cage 31 prevents that the top ends of plate 32 is about to by entrance hall threshold 36 (step S17 is for being), drive air- stream generating device 10a, 10b specified time (step S18) by actuating device 11.

Like this, except falling the top ends that prevents plate 32 is convex, also be provided with air-stream generating device 10a in the bottom of cage 31,10b is provided with air- stream generating device 10c, 10d in the upper end of cage 31, like this, by drive these air-stream generating devices respectively when cage 31 descends and rises, the pressure variation in the time of can relaxing by narrow further by the effect of plasma air-flow reduces the aerodynamic force noise.

Again, in above-mentioned the 4th embodiment, show the bottom of cage 31 and the top ends of upper end all are set to converx example, but the also shape shown in Fig. 9～17.

Further, the upper end side of cage 31 and bottom side, different shape also capable of being combined constitutes.Again, air- stream generating device 10a, 10b, 10c, the setting of 10d and number also are not limited to Figure 22 A, and the example shown in Figure 22 B can carry out suitable variation.

Then, the variation to the 4th embodiment describes.

(variation)

The formation of the cage when Figure 24 shows number being set changing of the variation medial end portions shape of the 4th embodiment and air-stream generating device.

In the variation of Figure 24, the top ends that prevents plate 32 that falls that the bottom of cage 31 is provided with is a triangle, and the top ends of the rectification campaign plate 39 that the upper end of cage 31 is provided with is one-sided bevelled shape.

Further, falling of lower end side prevents that plate 32 is provided with three air- stream generating device 10a, 10b, and 10c causes stream 25 to produce to ascent direction.The rectification campaign plate 39 of upper end side is provided with three air- stream generating device 10d, 10e, and 10f causes stream 25 to produce to descent direction.

Air- stream generating device 10a, 10b, 10c and air- stream generating device 10d, 10e, 10f was driven by actuating device shown in Figure 21 12 in the moment of regulation.The moment of regulation specifically, is the moment of the bottom of cage 31 cage 31 when descending by entrance hall threshold 36, and the upper end of cage 31 cage 31 when rising is by the moment of entrance hall threshold 36.

Like this, also identical with the 3rd embodiment even under the situation that number is set that changes end shape and air-stream generating device, the pressure variation when further relaxing by narrow under the effect of end shape and plasma air-flow is to reduce the aerodynamic force noise.

(the 5th embodiment)

Then the 5th embodiment is described.

In above-mentioned first～the 4th embodiment, be that shape to the top ends of cage designs to reduce the aerodynamic force noise, and in the 5th embodiment, be that top ends shape to balance block designs, can reduce balance block and cage so mutually through the aerodynamic force noise and the vibration of out-of-date generation.

Figure 25 A, Figure 25 B shows the structure of the lift appliance that the 5th embodiment relates to, and Figure 25 A is the scheme drawing that shows the structure of observing the cage of advancing in the hoist trunk and balance block from the side, and Figure 25 B shows the front view of observing this balance block from the A direction.Again, Figure 25 A, among Figure 25 B and Figure 18 A, the identical part of the structure of Figure 18 B (bottom of cage 31 is converx structure with the upper end) is represented with prosign, and is omitted its explanation.

At Figure 25 A, among Figure 25 B, the state that cage 31 and balance block 41 miss when showing cage 31 declines.Balance block 41 is installed in the other end of cable 34, and driving by the winch that do not show of figure and cage 31 1 coexist and do bucket type in the hoist trunk 35 and move.

Herein, at the intermediate floor place of hoist trunk 35, when balance block 41 and cage 31 missed mutually, the top ends of balance block 41 produced the local stream of peeling off, and produced the aerodynamic force noise thereby produce bigger pressure variation, made cage 31 produce vibration.

Shown in Figure 25 B, in the bottom of balance block 41 rectification campaign plate 42 that has towards the outstanding protuberance 42a of descent direction is set, and the rectification campaign plate 43 that has towards the outstanding protuberance 43a of ascent direction is set in the upper end of balance plate 41.Be formed at the protuberance 42a of top ends of rectification campaign plate 42,43,43a has and suppresses cage 31 and balance block 41 mutually through the out-of-date effect of peeling off stream that produces in the top ends of rectification campaign plate 42,43.Again, rectification campaign plate can pass through bonding, welding or screw fixed etc. and fixes.

Like this, because the upper end of balance block 41 and the top ends of bottom are set to convex, mutually through out-of-date, the air-flow that the top ends place is subjected to can obtain diffusion at the interlayer place of hoist trunk 35 balance block 41 and car 31.Thereby, suppress to flow into, and relax thing followed pressure variation towards the air-flow rapidly of the face relative of balance block 41 with cage 31.Like this, can reduce mutually through out-of-date aerodynamic force noise and vibration.

In above-mentioned the 5th embodiment, be arranged at the rectification campaign plate 42 at the both ends of balance block 41 again,, 43 top ends forms convex, if but it is shaped as the direct of travel with respect to balance block 41, and the cross-sectional area of horizontal direction is local different, even if other shapes can obtain same effect too.Specifically, as the variation of cage 31 is illustrated, also can be the different shape shown in Fig. 9～17, also can constitute in upper end side and bottom side combination different shape.

Variation to above-mentioned the 5th embodiment describes below.

(variation)

Figure 26 is the scheme drawing of the Facad structure of balance block when showing the top ends alteration of form of rectification campaign plate in the variation of above-mentioned the 5th embodiment.

Top ends at the rectification campaign plate 43 of the upper end side that is arranged at balance block 41 shown in the variation of Figure 26 forms leg-of-mutton example.This protrusion 43b is the triangle that its transverse width of ascent direction (width of horizontal direction) towards balance block 41 narrows down gradually.Again, the angle of inclination of this protrusion 43b etc. in advance by experiment or numerical analysis be designed to only value, with effective inhibition and cage 31 mutually through out-of-date air-flow rapidly.

Like this, even make the structure of the upper end of rectification campaign plate 39, also can spread through out-of-date air-flow mutually in top ends at intermediate floor place and cage 31 to lopsidedness.And the air-flow that top ends is subjected to can be to the diffusion of a side of balance block 41, therefore can further suppress towards the air-flow rapidly of the face relative with cage 31, to reduce aerodynamic force noise and the vibration that produces along with the pressure variation of this moment.

,, also can adopt Fig. 9～13, the shape shown in Figure 15～17 herein though show the top ends bevelled example of rectification campaign plate 39 again.Further, the upper end of balance block 41 and bottom side place can adopt the combination of different shape to constitute.

(the 6th embodiment)

Below, the 6th embodiment is described.

In the 6th embodiment, the aerodynamic force noise problem when descending in order to solve cage is provided with air-stream generating device to the upper end and the bottom of cage.

Figure 27 A, Figure 27 B shows its structure.

Figure 27 A, Figure 27 B are the scheme drawings of the structure of the lift appliance that shows that the 6th embodiment relates to, and Figure 27 A is the cage of advancing in the hoist trunk and the side observation figure of balance block, and Figure 27 B is a front view of observing this balance block from the A direction.Again, with Figure 25 A of described the 5th embodiment, the additional same-sign of the part that Figure 25 B is identical, and omit its explanation.

Identical with described the 5th embodiment, the bottom of balance block 41 is equipped with converx rectification campaign plate 42, again, is provided with converx rectification campaign plate 43 in the upper end.Can be suppressed at intermediate floor place and cage 31 so mutually through out-of-date air-flow rapidly, and reduce the aerodynamic force noise that the pressure variation of this moment brings towards the face relative with cage 31.

Here, in the 6th embodiment, further, the rectification campaign plate 42 of the bottom of balance block 41 is provided with air-stream generating device 10a, 10b.While also is provided with same air- stream generating device 10c, 10d on the rectification campaign plate 43 of the upper end of balance block 41.

These air- stream generating devices 10a, 10b, 10c, 10d utilize plasma discharging to cause stream 25 towards the direction generation of regulation.Here, air- stream generating device 10a, 10b produce to ascent direction and cause stream 25, and air- stream generating device 10c, 10d produce to descent direction and cause stream 25.

As mentioned above, air- stream generating device 10a, 10b, 10c, 10d are to be the modular construction of basal disc with insulators such as potteries, module section can be fixed in balance block 41 simply by screw clamp or adhesive agent etc.

Again, these air- stream generating devices 10a, 10b, 10c, 10d is driven by the moment of control setup shown in Figure 21 12 in regulation when cage 31 is advanced.The moment of regulation specifically, is the bottom of cage 31 balance block 41 when rising and the moment of cage 31 mutual processes, and the upper end of balance block 41 and the moment of cage 31 mutual processes during car decline.

Actuating device 11 is arranged on the balance block 41.Control setup 12 shown in Figure 21 detects the position of cage 31 based on the position signal from device for detection of position of car body 13 outputs, in the moment of cage 31 and balance block 41 mutual processes, by actuating device 11 drive controlling air- stream generating device 10a, 10b, with air-stream generating device 10c, 10d.Again, the actuating device on control setup 12 and the balance block 41 is electrically connected by the cable that do not show of figure or by wireless.

By such structure, when the bottom of balance block 41 is through cage 31 when cage 31 rises, air- stream generating device 10a, 10b is driven, and produces towards the direction (ascent direction) opposite with the direct of travel of balance block 41 to cause stream 25.When the upper end of balance block 41 is through car 31 when cage 31 descends on the other hand, air- stream generating device 10c, 10d is driven, and produces towards the direction (descent direction) opposite with the direct of travel of balance block 41 to cause stream 25.

Like this, except the upper and lower end parts of balance block 41 is a convex, be provided with air-stream generating device 10a in the bottom of balance block 41 further, 10b is provided with air- stream generating device 10c, 10d in the upper end, like this, by when cage 31 descends and rises, driving these air-stream generating devices respectively, can relax cage 31 and balance block 41 by the effect of plasma air-flow further mutually through out-of-date pressure variation, reduce the aerodynamic force noise.

Again,, among the 27B, show the bottom of balance block 41 and the top ends of upper end converx example all is set at Figure 27 A, but the also shape shown in Fig. 9～17.Further, the upper end side of cage 31 and bottom side, the also combination of different shape.

Again, air- stream generating device 10a, 10b, 10c, the setting of 10d and number also are not limited to Figure 27 A, and the example shown in Figure 27 B can carry out suitable variation.

(the 7th embodiment)

Then, the 7th embodiment is described.

In the 7th embodiment, cage and balance block both are provided with air-stream generating device.

Figure 28 A, Figure 28 B has shown such structure.

Figure 28 A, Figure 28 B, Figure 28 C is the scheme drawing of the structure of the lift appliance that shows that the 7th embodiment relates to, Figure 28 A is the cage of advancing in the hoist trunk and the side observation figure of balance block, Figure 28 B is a front view of observing this cage from the A1 direction, and Figure 28 C is a front view of observing balance block from the A2 direction.Again, with Figure 25 A of described the 5th embodiment, the additional same-sign of the part that Figure 25 B is identical, and omit its explanation.

In the 7th embodiment, cage 31 and balance block 41 all are provided with air-stream generating device.That is, the falling of the bottom of cage 31 prevents the air-stream generating device 10a that is provided with on the plate 32, and the air-stream generating device 10c that the rectification campaign plate 39 of 10b and its upper end is provided with, the 10d wall with the hall side of hoist trunk 35 respectively are relative.

For balance block 41, the air-stream generating device 10e on the rectification campaign plate 42 of its bottom, the air-stream generating device 10g on the rectification campaign plate 43 of 10f and upper end, 10h are separately positioned on the face relative with cage 31.

Be arranged on the air-stream generating device 10a on the cage 31,10b, 10c, 10d is driven in the moment of regulation by the first actuating device 11a when cage 31 is advanced.The moment of regulation, specifically, be the top ends of cage 31 rectification campaign plate 39 when rising during by entrance hall threshold 36 and cage 31 fall the top ends during that prevents plate 32 when descending by entrance hall threshold 36.

The first actuating device 11a is arranged on the cage 31.Control setup 12 as shown in figure 21 is as first control part, detect the position of cage 31 based on position signal from device for detection of position of car body 13 outputs, when cage 31 passes through assigned position, by the first actuating device 11a to air- stream generating device 10a, 10b, with air- stream generating device 10c, 10d carries out drive controlling.

By such structure, when the top ends of rectification campaign plate 39 was by entrance hall threshold 36 when cage 31 rose, gas generating unit 10c, 10d is driven, towards descent direction generation the causing stream 25 of cage 31.On the other hand, when descending, cage 31 falls the top ends during that prevents plate 32 by entrance hall threshold 36, gas generating unit 10a, and 10b is driven, and produces towards the ascent direction of cage 31 to cause stream 25.

Again, set air-stream generating device 10e on the balance block 41,10f, 10g, 10h is driven in the moment of regulation by the second actuating device 11b when balance block 41 is advanced.The moment of regulation specifically, is the bottom of cage 31 balance block 41 when rising and the moment of cage 31 mutual processes, and the upper end of balance block 41 and the moment of cage 31 mutual processes during cage 31 declines.

The second actuating device 11b is arranged on the balance block 41.Control setup 12 shown in Figure 21 detects the position of cage 31 based on the position signal from device for detection of position of car body 13 outputs as second control part, in the moment of cage 31 and balance block 41 mutual processes, by the second actuating device 11b drive controlling air- stream generating device 10e, 10f, with air-stream generating device 10g, 10h.Again, the second actuating device 11b on control setup 12 and the balance block 41 is electrically connected by the cable that do not show of figure or by wireless.

By such structure, when the bottom of balance block 41 is through cage 31 when cage 31 rises, air- stream generating device 10e, 10f is driven, and produces towards the direction (ascent direction) opposite with the direct of travel of balance block 41 to cause stream 25.

On the other hand, when the upper end of balance block 41 is through cage 31 when cage 31 descends, air- stream generating device 10g, 10h is driven, and produces towards the direction (descent direction) opposite with the direct of travel of balance block 41 to cause stream 25.

Like this, by at cage 31 and balance block 41 air-stream generating device 10a～10d being set simultaneously, air-stream generating device 10e～10h, and produce the suitable stream 25 that causes constantly at each, the aerodynamic force noise that produces in the time of can suppressing cage 31 by narrow 37 such as entrance hall thresholds 36, and cage 31 and balance block 41 mutual aerodynamic force noise and vibrations through out-of-date generation.The lift appliance of ride comfort can be provided like this.

Again,, in the example of 28B, show the bottom of cage 31 and balance block 41 and the top ends of upper end and all be set to converx example at Figure 28 A, but the also shape shown in Fig. 9～17.

Further, the upper end side of cage 31 and balance block 41 and bottom side, also constituting of different shape.Again, air-stream generating device 10a～10d, the setting of airflow apparatus 10e～10h and number also are not limited to Figure 28 A, and the example shown in Figure 28 B can carry out suitable variation.

In brief, the present invention is not limited to the respective embodiments described above, the implementation phase can be on the basis that does not break away from purport inscape be out of shape and specialize.By the appropriate combination of a plurality of inscapes that the various embodiments described above disclosed, can form various inventions again.For example, also can from the described inscape of embodiment, remove several inscapes.Also the inscape among the different embodiment can be carried out appropriate combination.

By the above embodiments, by being arranged on the effect of the rectification campaign plate on the cage, the air-flow rapidly towards the car front in the time of can suppressing the narrow of cage by hoist trunk flows into, and reduces the aerodynamic force noise.

Again, the effect of the shape by being arranged on the rectification campaign plate on the balance block can suppress cage and balance block and flow into through the air-flow rapidly of the out-of-date face relative with cage towards balance block mutually, to reduce the aerodynamic force noise.
