Brief summary of the invention
The problem that invention will solve
But, in the technology disclosed in patent documentation 1 and patent documentation 2, in the mode closing the gap between layer door, consideration is made to smoke retaining and sound-proofing, but because layer door is between hoist trunk and car entrance hall, the situation that larger barometric fluctuation occurs between hoist trunk and car entrance hall across layer door is little, so sufficient consideration has been made in the not talkative change to air pressure.
Namely, in the elevator with Pneumatic controller, lift car inside and outside between there is draught head, in the prior art, when air pressure in lift car raises, by the impact of draught head, produce the power in the direction that elevator door and lift car are separated, by the impact of this power, the gap between elevator door and lift car may be made to become large and cause sealing property to decline.In addition, be subject to the impact of the draught head inside and outside lift car, can produce and be intended to containment member toward the power that pushes back, namely make containment member and the power in the direction of gap enlargement between the car door contacted with containment member.Containment member self pushes back under this force and by past, thus possibly cannot ensure sealing property.
In addition, the gate open of lift facility is often made up of multiple leaf door, in each fan door, the motion track of limiting door is carried out by the Suspension guide rail that is arranged on a top and the door that is arranged on a bottom, in order to enable elevator door successfully carry out opening and closing, the track in the direction vertical with opening and closing direction limits direction setting rich measuring.Therefore, such as in the lift facility be made up of two fan doors, when elevator door cuts out, the door deflection lift car lateral direction of a side may be there is, and the car door of the opposing party is partial to the situation in direction inside lift car, the multiple leaf door door plane separately of elevator might not keep at grade.In addition, even if only have a door leaf, rear end side also likely occurs towards the skew of lift car lateral direction, front is towards the situation of direction skew inside lift car.
That is, in the lift facility be made up of multiple door leaf, occur that door that should be airtight exists the situation of ladder difference each other sometimes, so it is poor to be difficult to deal with above-mentioned ladder by a containment member, possibly cannot maintain the sealing property of lift car.Equally, even if only have a door leaf, also there will be skew, also likely can maintain the sealing property of lift car.
Therefore, need to develop a kind of bubble-tight obturator that can keep lift car, when making there is draught head and make to act on effectively on car door or airtight component because of this draught head inside and outside the car door of the elevator controlled the air pressure in cage, or when car door exists ladder difference, the air-tightness of lift car also can be kept.

Between described tight mechanism main body 9 and S. A. 10, be provided with torque spring 11, torque spring 11 form at ordinary times on the direction that airtight component 12 leaves car door 1 to tight mechanism main body 9 exert a force force application mechanism.
Tight mechanism main body 9 is provided with rod member 32 and engaging roller, and this rod member 32 extends on the direction perpendicular to S. A. 10, and this engaging roller is arranged on and separates on the position of the distance of regulation with the S. A. 10 of rod member 32.In addition, car door 1 is provided with and the tilting cam 7 engaging roller 8 and engage.
So, the car door obturator 21 in present embodiment has tight mechanism main body 9, airtight component 12, torque spring 11 as force application component, rod member 32, engaging roller 8 and tilting cam 7.
Fig. 4 is the top plan view of the B-B section representing Fig. 3.Tight mechanism main body 9 in present embodiment and the length of airtight component 12 are configured to and the same length on the Width of car door 1.In addition, being fixed on the tilting cam 7 on car door 1 and engaging roller 8 is provided with multiple.In the present embodiment, the end of the opening direction of car door 1 is provided with tilting cam 7a, and on the end of the closing direction of car door 1, is provided with tilting cam 7b.Be provided with engaging roller 8a and engaging roller 8b, above-mentioned engaging roller 8a and engaging roller 8b in addition and be provided in car door 1 when being about to close completely, abut with each tilting cam 7 in multiple tilting cam 7 respectively.
The power of door machine 3 is delivered on roller 5 via driving band 4, Suspension 15 is moved on Suspension guide rail 6 along the direction of closing the door, along with the movement of Suspension 15, car door 1 is in closed condition, be arranged on tilting cam 7a on car door 1 and tilting cam 7b to engage with engaging roller 8a and engage roller 8b respectively, engage roller 8 and pressed by towards the direction separated with car door 1 centered by S. A. 10.
Pressed engaging roller 8 by tilting cam 7, tight mechanism main body 9 rotates towards by airtight component 12 by the direction be pressed on car door 1 centered by S. A. 10.Along with the pressing fastened roller 8 of described tilting cam 7, close to car door 1, when car door 1 is closed completely, the anglec of rotation of tight mechanism main body reaches maxim to the airtight component 12 being arranged in tight mechanism main body 9.Now, the front end of airtight component 12 contacts with car door 1 and this front end occurs bending.Thereby, it is possible to utilize airtight component 12 to seal the gap between car door 1 and side panel 17.
; when car door 1 is made up of the above multiple leaf door of two fans; although the motion track of car door 1 receives the restriction of the Suspension guide rail 6 being arranged on car door top and the door being arranged on car door bottom; but in order to make on-off action carry out smoothly, the track in the direction vertical with opening and closing direction is provided with rich measuring on limiting.Therefore, an end in the left and right end portions of the car door 1 of elevator is arranged in the position of the side near outside and inner side of lift car 16, and another end is arranged in the position of the opposite side near inner side and outer side of lift car 16.In these cases, owing to not closing abreast with top framework 14, so the distance such as between tilting cam 7a and top framework 14 is greater than the distance between tilting cam 7b and top framework 14, tilting cam 7a and the engaging depth shallower engaged between roller 8a may be caused.
On the other hand, because tilting cam 7b is greater than common engaging amount with the engaging amount engaged between roller 8b, so the anglec of rotation of tight mechanism main body 9 is greater than the common anglec of rotation, airtight component 12 is greater than common Exposure with the Exposure of car door 1.According to this structure, can block between the car door 1 of tilting cam 7a side and top framework 14 and become large gap.
In addition, in the present embodiment, often fan car door 1 and be equipped with car door obturator, so such as when many fan car doors 1 have occurred when closing tilting and caused creating ladder difference between car door end face butted part separately, also airtight component 12 can be utilized to close gap between car door 1 and top framework 14, thus can seal more effectively.
When described car door 1 is in closed condition, lift car 16 is in the state can carrying out being elevated.By making blowing engine 20 action, to the indoor importing air of lift car 16.So, because the gap between car door 1 and side panel is closed by airtight component 12, so the air pressure by lift car side of airtight component 12 is greater than the air pressure by car door side of airtight component 12, according to this draught head, the airtight component 12 of front end softness bends further, fully can eliminate the gap between lift car and car door 1 thus.
Airtight component 12 is arranged on ratio S. A. 10 position more on the lower of tight mechanism main body 9, and hand of rotation when tight mechanism main body 9 makes airtight component 12 contact with car door 1 and the pressure increase in lift car, to being identical direction higher than the direction pressing airtight component 12 during pressure outside lift car under the effect of car internal gas pressure, can keep air-tightness thus further effectively.
In addition, the same with the situation of the distortion of the airtight component 12 that draught head causes, in car door, the air pressure of inner side of 1 is greater than the air pressure in the outside of car door 1, car door 1 by the trend released toward the outer side, distance between car door 1 and top framework changes, gap between car door 1 and airtight component 12 becomes greatly, and the air imported in lift car 16 from blowing engine 20 thus leaks sometimes from the gap between this car door 1 and airtight component 12.
But, extend due to the rod member making tight mechanism main body 9 rotate 32 is arranged on the direction vertical with S. A. 10, and be provided with on the position separating the distance of regulation with S. A. 10 and engage roller 8, so can lever principle be utilized, the rotation amount of further increasing tight mechanism main body 9, airtight component 12 is contacted more closely with car door 1, the distortion of airtight component 12 can be utilized thus and make to be difficult to produce gap.
In addition, even if having air from the clearance leakage between described car door 1 and airtight component 12, by current plate 13a, the air of leakage is flowed towards the front of current plate 13b, under the effect of this blast, tight mechanism main body 9 is towards the right handed trend of Fig. 3 centered by S. A., the gap shrinks between described car door 1 and airtight component 12.
The power of door machine 3 is delivered on roller 5 via driving band 4, Suspension 15 is moved on Suspension guide rail 6 along the direction of opening the door, along with the movement of Suspension 15, car door 1 is in open mode, tilting cam 7 is removed with the engaging engaged between roller 8, tight mechanism main body 9 is under the effect of the counter-force of torque spring 11, and rotate towards the anticlockwise direction shown in Fig. 3, the direction namely leaving car door 1 towards airtight component 12 rotates.Thus, airtight component 12 separates with car door 1, even if car door slides, because airtight component 12 does not contact with car door 1, so can prevent airtight component 12 from wearing away.
According to said structure, by arranging multiple engaging roller 8 and tilting cam 7, the phenomenon producing gap because car door tilts can be overcome, thus the air-tightness of lift car can be kept.Owing to being all provided with car door obturator often fanning on car door, even if so make to produce between the interface of car door ladder difference because of car door run-off the straight, gap also can being avoided to produce, thus the air-tightness of lift car can be kept.
In addition, when utilizing the draught head inside and outside lift car to control the air pressure required in bubble-tight lift car, containment member meeting auto Deformation, thus the air-tightness of lift car can be kept.
In addition, utilize and be arranged to right current plate, the gap between car door and airtight component, once become large, also can reduce this gap.
Therefore, obturator proposed by the invention is dynamic role obturator, automatically can eliminate the gap between car door and side panel, thus can keep the air-tightness of lift car.
