The problem that invention will solve
The ratio that the horizontal section area of ratio or lift car that the flowing velocity of the air flowed between the peripheral wall surfaces and the internal face of hoist trunk of lift car roughly accounts for hoist trunk area by the speed of lift car, gap between the peripheral wall surfaces of lift car and the internal face of hoist trunk accounts for hoist trunk area determines.Further, the noise in the lift car produced when lift car travels accelerates along with speed air flow and increases.
On the other hand, lease than (floor area can leasing area and income section accounts for the ratio of the gross area) as far as possible effectively to utilize floor area in order to what increase building, the owner of building tends to reduce as far as possible the area of elevator lifting channel ratio shared between floors.The horizontal section area of elevator lifting channel is less, can lease than larger, and concerning the owner of building, the effective rate of utilization of building resources is larger.
In the elevator disclosed in patent documentation 1, by reducing along with the movement of lift car at the relative velocity of the air of lift car ambient dynamic, can inhibit function noise on the elevator car.
; according to patent documentation 1; assuming that the horizontal section area of hoist trunk is constant; then in order to arrange the ventilator tube linked up by upper and lower hoist trunk; need the gap significantly reduced between the peripheral wall surfaces of lift car and the internal face of hoist trunk; the speed of the air do not flowed between the peripheral wall surfaces of lift car and the internal face of hoist trunk via ventilator tube is accelerated, causes noise to increase.
In addition, owing to being provided with ventilator tube, the horizontal section area passed through for lift car is corresponding to diminish.When gap between the peripheral wall surfaces by increasing lift car and the internal face of hoist trunk reduces air velocity, if do not change the horizontal section area of hoist trunk, then the method reducing car size can be taked to deal with.On the other hand, if do not change the size of lift car, then the method for the horizontal section area expanding hoist trunk can be taked to deal with.As mentioned above, there is limitation in the method expanding the horizontal section area of hoist trunk in order to the noise reduced in lift car, and no matter adopt any method, all need significantly to transform lift car or hoist trunk, so not the countermeasure of reality.
Therefore, need to develop the countermeasure not needing lift car or hoist trunk significantly to be transformed to the air velocity that just can be reduced in lift car ambient dynamic.
Summary of the invention
The object of the present invention is to provide a kind of hoist trunk device of elevator, make not need the horizontal section area changing elevator lifting channel just effectively can reduce the flowing velocity of the air between the peripheral wall surfaces of hoist trunk and inner wall of elevator cage face, thus can inhibit function noise on the elevator car.

Detailed description of the invention
Below, be described in detail to embodiments of the present invention with reference to accompanying drawing, but the present invention is not subject to the restriction of following embodiment, the various variation of carrying out in technological concept of the present invention and application examples are also included within scope of the present invention.
First embodiment
Fig. 1 is the horizontal cross of the hoist trunk device involved by the first embodiment of the present invention, shows the example of the independent hoist trunk arranging a lift car in a hoist trunk.
As shown in Figure 1, in the first hoist trunk 1A of elevator, lift car 2A and counterbalanced weight 3A is can arrange in the mode of above-below direction lifting.Lift car 2A and counterbalanced weight 3A is linked by main hoist cable, by carrying out traction with winch to this main hoist cable, lift car 2A and counterbalanced weight 3A is elevated at above-below direction.In addition, winch is controlled by not shown control setup.The wall of hoist trunk 1A is fixed with the guide rail 4A guiding lift car 2A movement and the guide rail 5A guiding counterbalanced weight 3A movement.
Equally, in the second hoist trunk 1B of elevator, lift car 2B and counterbalanced weight 3B is can arrange in the mode of above-below direction lifting.Lift car 2B and counterbalanced weight 3B is linked by main hoist cable, by carrying out traction with winch to this main hoist cable, lift car 2B and counterbalanced weight 3B is elevated at above-below direction.Winch is controlled by not shown control setup.The wall of hoist trunk 1B is fixed with the guide rail 4B guiding lift car 2B movement and the guide rail 5B guiding counterbalanced weight 3B movement.
When lift car 2A, 2B carry out lifting action along above-below direction, in hoist trunk 1A, 1B, produce the air flowing of certain speed, the flowing velocity of this air depends on the moving velocity of the ratio that the sectional area of lift car 2A, 2B and counterbalanced weight 3A, 3B occupies in the horizontal section area of hoist trunk and lift car 2A, 2B.The direction of this air flowing is contrary with the moving direction of lift car, and flowing velocity is faster than the moving velocity of lift car, and its result can produce very large noise, brings discomfort in this noise transmission to lift car the passenger in lift car.In general, the noise of known action on lift car 2A, 2B with increased pro rata by 6 powers of the flowing velocity of lift car 2A, 2B ambient air, along with the flowing velocity by lift car 2A, 2B ambient air increases, need the measure taking to reduce noise.
In order to reduce above-mentioned noise, in the present embodiment, the interface channel 6 being configured by the cross sectional area with regulation connects between the first hoist trunk 1A and the second hoist trunk 1B.This interface channel 6 connects each hoist trunk 1A, 1B in the position that the most significant bit of the shift motion than lift car 2A, 2B sets high or in the position that the lowest order of the shift motion than lift car 2A, 2B sets low.In the present embodiment, the position set high in the most significant bit of the shift motion than lift car 2A, 2B is adopted to connect the interface channel 6 of each hoist trunk 1A, 1B.This interface channel 6 can utilize the spatial placement between the floor of building.
In interface channel 6, being provided with supply ventilating fan 7, by making air flow between hoist trunk 1A and hoist trunk 1B energetically, the pressure of hoist trunk 1A and hoist trunk 1B can being adjusted.Supply ventilating fan 7 is made up of a pair electric blowing machine 7A, 7B, and its rotation is controlled by not shown control setup.Owing to have employed as electric blowing machine 7A, 7B towards an air fed electric blowing machine in direction, so employ two electric blowing machines, and if towards two-way air fed supply ventilating fan, then can only need use supply ventilating fan.
Below action when adopting said structure is described.Such as, when being arranged on the lift car 2A in the first hoist trunk 1A and carrying out declining mobile, be subject to the pressing of lift car 2A, while the pressure increase of lift car 2A lower side, the pressure drop of lift car 2A upper side, under the effect of this difference of pressure, the air of lift car 2A lower side is flowed by the upper side of the gap between the peripheral wall surfaces of lift car 2A and the internal face of hoist trunk 1A towards lift car 2A.Therefore, if this difference of pressure can be reduced, the speed of lift car 2A ambient air can be just decreased through.
In the present embodiment, the moving direction of lift car 2A can be judged by control setup, so be arranged to drive electric blowing machine 7A and attract air from hoist trunk 1B, and the air from hoist trunk 1B is supplied to the hoist trunk 1A (its pressure is in decline) of the upper side of the lift car 2A be arranged in hoist trunk 1A.Thus, by making the pressure increase of the upper side of the lift car 2A in hoist trunk 1A, the difference of pressure before and after lift car 2A can be reduced, the flowing velocity of lift car 2A ambient air can be decreased through.
On the contrary, when lift car 2A carries out rising mobile, be subject to the pressing of lift car 2A, while the pressure increase of lift car 2A upper side, the pressure drop of lift car 2A lower side, under the effect of this difference of pressure, the air of lift car 2A upper side is flowed by the lower side of the gap between the peripheral wall surfaces of lift car 2A and the internal face of hoist trunk 1A towards lift car 2A.
Therefore, electric blowing machine 7B is driven and attracts air from hoist trunk 1A, and the hoist trunk 1A (its pressure is in rising) of this air from the lift car 2A upper side be arranged in hoist trunk 1A is supplied to hoist trunk 1B.Thus, by reducing the pressure in the hoist trunk 1A of the upper side of lift car 2A, the difference of pressure of (lift car 2A's is upper and lower) before and after lift car 2A can be reduced, the flowing velocity of lift car 2A ambient air can be decreased through thus.
Equally, when being arranged on the lift car 2B in the second hoist trunk 1B and carrying out declining mobile, electric blowing machine 7B driven and attracts air from hoist trunk 1A, and the air from hoist trunk 1A being supplied to the hoist trunk 1B (its pressure is in decline) of the upper side of the lift car 2B be arranged in hoist trunk 1B.On the contrary, when being arranged on the lift car 2B in the second hoist trunk 1B and carrying out rising mobile, electric blowing machine 7A is driven and attracts air from hoist trunk 1B, and the hoist trunk 1B (its pressure in rising) of this air from the upper side of the lift car 2B be arranged in hoist trunk 1B is supplied to hoist trunk 1A.
At this, when the first lift car 2A and the second lift car 2B moves in the same direction, because the change conditions of the pressure in the first hoist trunk 1A and the second hoist trunk 1B presents identical trend, so make supply ventilating fan 7 stop action by control setup, the above-mentioned functions of interface channel 7 can be stopped thus.Further, also can be controlled on the contrary by the moving direction of control setup by the first lift car 2A and the second lift car 2B, make the pressure in the first hoist trunk 1A and the second hoist trunk 1B present contrary pressure trend.
As mentioned above, according to the present embodiment, owing to not needing to arrange ventilator tube in hoist trunk, so do not need the horizontal section area changing hoist trunk.And, due to can when lift car moves by air-supply arrangement adjustment lift car working direction on front side of (be the upside of lift car during rising, be the downside of lift car during decline) or working direction on rear side of (be the downside of lift car during rising, be the upside of lift car during decline) pressure, so the flowing velocity of the air between the peripheral wall surfaces of lift car and the internal face of hoist trunk effectively can be reduced, thus can inhibit function noise on the elevator car.

Equally, in the first hoist trunk 1B of elevator, lift car 2B-1,2B-2 and counterbalanced weight 3B-1,3B-2 are can arrange in the mode of above-below direction lifting.Lift car 2B-1,2B-2 and counterbalanced weight 3B-1,3B-2 are corresponding thereto linked by main hoist cable, by carrying out traction with winch to this main hoist cable, lift car 2B-1,2B-2 and counterbalanced weight 3B-1,3B-2 are elevated at above-below direction.In addition, winch is controlled by not shown control setup.The wall of hoist trunk 1B is fixed with and guides guide rail 4B-1,4B-2 of lift car 2B-1,2B-2 movement and guide rail 5B-1,5B-2 of guiding counterbalanced weight 3B-1,3B-2 movement.
In addition, the same with the first embodiment, connected between the first hoist trunk 1A and the first hoist trunk 1B by the interface channel 6 with the cross sectional area of regulation.The position set high in the most significant bit of the shift motion than lift car 2A, 2B is adopted to connect the interface channel 6 of each hoist trunk 1A, 1B in the present embodiment.
In interface channel 6, being provided with supply ventilating fan 7, by making air flow between hoist trunk 1A and hoist trunk 1B energetically, the pressure of hoist trunk 1A and hoist trunk 1B can being adjusted.Supply ventilating fan 7 is made up of a pair electric blowing machine 7A, 7B, and its rotation is controlled by not shown control setup.
Because the action of the elevator lifting channel device in the present embodiment is identical with the first embodiment, so omit its explanation repeated at this.Be with the difference of the first embodiment, the hoist trunk of the first embodiment is the independent hoist trunk arranging a lift car in a hoist trunk, and in the present embodiment, hoist trunk is the type that the is arranged side by side hoist trunk being arranged side by side two lift cars in a hoist trunk.
When independent hoist trunk, when being arranged on lift car 2A, 2B in contiguous two hoist trunks 1A, 1B and moving in the same direction, as in a first embodiment, sometimes need the function stopping interface channel 6.
; when using the type that is arranged side by side hoist trunk 1A, 1B shown in the present embodiment; due to each lift car 2B-1,2B-2 in each lift car 2A-1,2A-2 in the first hoist trunk 1A and the second hoist trunk 1B, the probability of movement is little in the same direction simultaneously, so the change conditions of pressure in the first hoist trunk 1A and the second hoist trunk 1B presents contrary trend mostly.Therefore, the illustrated in a first embodiment essentiality of interface channel 6 hold function that makes reduces.
It should be noted that, in the first embodiment and the second embodiment the reduction effect of effect noise is on the elevator car illustrated.On the other hand, owing to reducing the noise produced in hoist trunk, can reduce before elevator doorway and the effect of noise in adjacent room so also have.In addition, in the embodiment of following explanation, also there is above-mentioned effect.

As mentioned above, according to the present embodiment, owing to not needing to arrange ventilator tube in hoist trunk, so do not need the horizontal section area changing hoist trunk.And, due to can when lift car moves by air-supply arrangement adjustment lift car working direction on front side of (be the upside of lift car during rising, be the downside of lift car during decline) or working direction on rear side of (be the downside of lift car during rising, be the upside of lift car during decline) pressure, so the flowing velocity of the air between the peripheral wall surfaces of lift car and the internal face of hoist trunk effectively can be reduced, thus can inhibit function noise on the elevator car.
4th embodiment
Below, the 4th embodiment of the present invention is described.The difference of present embodiment and above-mentioned embodiment is, in the present embodiment, except interface channel 6, is also provided with the second interface channel that the position set low at the lowest order of the shift motion than lift car 2A, 2B connects hoist trunk.According to this structure, the pressure before and after lift car can be adjusted more energetically.
Fig. 4 is the longitudinal sectional view of the elevator lifting channel device involved by the 4th embodiment of the present invention, and as shown in Figure 4, elevator is made up of such as lower member: be arranged on lift car 2A, the 2B in the first hoist trunk 1A and the second hoist trunk 1B; Be arranged on the winch 11A, the 11B that are driven above-mentioned lift car 2A, 2B by main hoist cable 9A, 9B in Machine Room 10A, 10B; Counterbalanced weight 3A, 3B of well-bucket shape is hung as by winch 11A, 11B; The bottom of link lift car 2A, 2B and counterbalanced weight 3A, 3B are with the compensates rope 12A compensated the overbalance of winch 11A, 11B, 12B; Tension force is applied with tension pulley 13A, 13B of making it carry out operating stably to compensates rope 12A, 12B; And to the attenuation units etc. that the action of the above-below direction of tension pulley 13A, 13B cushions.Winch 11A, 11B are controlled by control setup 17A, the 17B be arranged in Machine Room 10A, 10B.
And, in the present embodiment, except interface channel 6 set in each embodiment above-mentioned, be also provided with the second interface channel 14 that the position set low at the lowest order of the shift motion than lift car 2A, 2B connects hoist trunk.This interface channel 14 is provided with electric blowing machine 15A, 15B.Therefore, the interface channel 6 of upside connects hoist trunk 1A, 1B of the upside of lift car 2A, 2B, and the interface channel 14 of downside connects hoist trunk 1A, 1B of the downside of lift car 2A, 2B.Because the pressure change of the upper side and lower side of lift car 2A, 2B presents contrary trend, so the action of electric blowing machine 15A, 15B of the action of electric blowing machine 7A, 7B of the interface channel 6 of upside and the interface channel 14 of downside is opposite each other.
Such as, the structure of the present embodiment is identical with the structure of the first embodiment, and carries out following actions.When being arranged on the lift car 2A in the first hoist trunk 1A and carrying out declining mobile, owing to being subject to the pressing of lift car 2A, while the pressure increase of lift car 2A lower side, the pressure drop of lift car 2A upper side, under the effect of this difference of pressure, the air of lift car 2A lower side is flowed by the upper side of the gap between the peripheral wall surfaces of lift car 2A and the internal face of hoist trunk 1A towards lift car 2A.
Due to the pressure drop on the upside of when lift car 2A moves, so drive electric blowing machine 7A by control setup 17A, attract air from hoist trunk 1B, and the air from hoist trunk 1B is supplied to the hoist trunk 1A of the upper side of lift car 2A.Thus, the pressure increase of the hoist trunk 1A of the upper side of lift car 2A is made.
On the other hand, due to the pressure increase on the downside of when lift car 2A moves, so drive electric blowing machine 15B, attract air from hoist trunk 1A, and this air is discharged to hoist trunk 1B from the hoist trunk 1A of the lower side of lift car 2A.Thus, the pressure drop of the hoist trunk 1A of the lower side of lift car 2A is made.Diminished by the difference of pressure of the front and back making the lift car 2A in hoist trunk 1 A, the flowing velocity of lift car 2A ambient air can be decreased through.
In contrast, when lift car 2A carries out rising mobile, be subject to the pressing of lift car 2A, while the pressure increase of lift car 2A upper side, the pressure drop of lift car 2A lower side, under the effect of this difference of pressure, the air of lift car 2A upper side is flowed by the lower side of the gap between the peripheral wall surfaces of lift car 2A and the internal face of hoist trunk 1A towards lift car 2A.
Due to the pressure increase of the upside of lift car 2A, so drive electric blowing machine 7B, discharge air from the hoist trunk 1A of the upper side of lift car 2A to hoist trunk 1B.Thereby, it is possible to make the pressure drop of the hoist trunk 1A of the upper side of lift car 2A.
On the other hand, due to the pressure drop of the downside of lift car 2A, so drive electric blowing machine 15A, attract air from hoist trunk 1B, and the air from hoist trunk 1B is supplied to the hoist trunk 1A of the lower side of lift car 2A.Thereby, it is possible to make the pressure increase of the hoist trunk 1A of the lower side of lift car 2A, the difference of pressure of the front and back of the lift car 2A in hoist trunk 1A is diminished, thus the flowing velocity of lift car 2A ambient air can be decreased through.Action in the second hoist trunk 1B is identical, and its effect is also identical.
As mentioned above, electric blowing machine 7A, 7B of being arranged in the interface channel 6 of upside and electric blowing machine 15A, 15B of being arranged in the interface channel 14 of downside is controlled according to the moving direction of lift car 2A, the pressure of the pressure of the upside of lift car 2A and downside can be made thus closer to each other, thus the relative velocity flowing through lift car 2A ambient air can be reduced, the generation of noise can be suppressed.More preferably method is, if the pressure of the pressure of the upside of lift car 2A and downside can be adjusted to roughly the same degree, then because the size of noise depends on the moving velocity of lift car 2A, completely so can reduce noise to greatest extent.In order to accomplish this point, detect the pressure of the hoist trunk 1A of the upper side and lower side of lift car 2A, and with the rotation making the approximating mode of above-mentioned pressure control electric blowing machine 7A, 7B and electric blowing machine 15A, 15B, can pressure adjustment be carried out thus.

In contrast to this, when lift car 2A carries out rising mobile, drive electric blowing machine 7A, attract air from hoist trunk 1A, and the hoist trunk 1A of this air from the upper side of lift car 2A is discharged to the outside via peristome 8.Thereby, it is possible to make the pressure drop of the hoist trunk 1A of the upper side of lift car 2A.On the other hand, due to the pressure drop of the downside of lift car 2A, so drive electric blowing machine 15A to attract air from peristome 16 from outside, and the air of outside is supplied to the hoist trunk of the lower side of lift car 2A, the pressure increase of the hoist trunk 1A of the lower side of lift car 2A can be made thus.By carrying out pressure adjustment as mentioned above, the difference of pressure of (lift car 2A's is upper and lower) before and after the lift car 2A in hoist trunk 1A can be reduced, the flowing velocity of lift car 2A ambient air can be decreased through.Action in the second hoist trunk 1B is identical, and its effect is also identical.
By adopting said structure, lift car 2A, 2B no matter in each hoist trunk 1A, 1B towards which direction move, and all can adjust the pressure of the hoist trunk of the upside of each lift car 2A, 2B.Therefore, do not need to make supply ventilating fan 7 stop action when lift car 2A and lift car 2B moves towards equidirectional by control setup, and there is no need the above-mentioned functions stopping interface channel 6 yet.
As mentioned above, according to the present embodiment, owing to not needing to arrange ventilator tube in hoist trunk, so do not need the horizontal section area changing hoist trunk.And, due to can adjust lift car when lift car moves energetically by air-supply arrangement working direction on front side of (be the upside of lift car during rising, be the downside of lift car during decline) and working direction on rear side of (be the downside of lift car during rising, be the upside of lift car during decline) pressure, so the flowing velocity of the air between the peripheral wall surfaces of lift car and the internal face of hoist trunk effectively can be reduced, thus can inhibit function noise on the elevator car.
