Next, a description will be given of a state of the station device 8 at the time of an earthquake with reference to fig. 9 to 13.
Fig. 9 is a front view showing a state of the landing system of an elevator according to embodiment 1 during an earthquake. Fig. 10 is a sectional view taken along line B-B of fig. 9. Fig. 11 is a sectional view taken along line C-C of fig. 9. Fig. 12 is a side view of the upper portion of the landing system of the elevator according to embodiment 1 when the upper portion is displaced to the inside of the hoistway during an earthquake. Fig. 13 is a side view of the upper part of the landing system of the elevator according to embodiment 1 when the upper part is displaced to the near side of the landing in an earthquake.
As shown in fig. 9 and 10, when the guide rail 5 and the landing doorway 7 are relatively displaced in the width direction of the landing doorway 7 during an earthquake, the door frame 21 and the sill device 13 follow the guide rail 5 to move in the width direction of the landing doorway 7 via the door device 12, the door connecting frame 14, the guide rail connecting mechanism 15, and the guide rail connecting frame 9. In this case, in the elevator in which the car 6 is engaged with the door device 12 to open and close the door 11, the engaged state is maintained.
When the guide rail 5 and the landing doorway 7 are relatively displaced in the width direction of the landing doorway 7 during an earthquake, the landing doorway 33 and the duct frame 29 are maintained in a state of being fixed to the base structure 1 without following the movement of the guide rail 5 in the width direction of the landing doorway 7 via the duct frame coupling mechanism 32.
As shown in fig. 11 to 13, when the guide rail 5 and the landing doorway 7 are relatively displaced in the depth direction of the landing doorway 7 during an earthquake, the door frame 21 is inclined in the depth direction of the landing doorway 7 following the guide rail 5 via the door device 12, the door connecting frame 14, the guide rail connecting mechanism 15, and the guide rail connecting frame 9.
At this time, the door coupling frame 14 slides in the height direction of the landing doorway 7 through the door coupling frame coupling mechanism 52 in the rail coupling mechanism 15. As a result, the distance between the rail coupling frame 9 and the rail coupling mechanism 15 and the like due to the deformation of the rail 5 is absorbed.
The landing device 8 is tilted to absorb relative displacement in the depth direction of the landing doorway 7 between the guide rail 5 and the landing doorway 7 during an earthquake. As a result, the sill device 13 and the floor do not need to be displaced in the depth direction. Thus, the floor of the landing may be a building floor. Further, the tunnel wall portion 36 and the tunnel ceiling portion 37 may be of a simple structure that can be displaced only in the depth direction.
Next, the sill device 13 will be described with reference to fig. 14.
Fig. 14 is a front view of a sill device of a landing system of an elevator according to embodiment 1 as viewed from a hoistway side. Fig. 15 is a sectional view taken along line D-D of fig. 14. Fig. 16 is a sectional view taken along line E-E of fig. 14. Fig. 17 is a sectional view taken along line F-F of fig. 14.
Fig. 14 is a left side view showing the center of the landing doorway 7. As shown in fig. 15 to 17, the sill device 13 includes a sill fixing portion 24, a sill movable portion 25, and a sill coupling mechanism 26.
The sill fixing portion 24 is fixed to a floor 27 of a landing of the base-side building body. The sill movable portion 25 is provided so as to be able to follow the displacement of the guide rail 5 in the width direction of the landing doorway 7. The sill coupling mechanism 26 couples the sill fixing portion 24 and the sill movable portion 25 to be slidable in the width direction of the doorway.
The sill 16 is provided to the sill movable portion 25. The sill 16 guides the door 11. The sill front panel 43 is disposed on the landing side of the sill 16.
The movable sill portion 25 is connected to the door connecting post 17 and the vertical frame 22. When the landing and the guide rail 5 are relatively displaced in the width direction of the landing doorway 7, the sill movable section 25 moves in the width direction of the landing doorway 7 following the guide rail 5.
The sill coupling mechanism 26 is disposed below the sill movable portion 25. The sill connecting mechanism 26 includes a roller support 39. The roller support 39 includes a roller support portion 40 and a roller portion 41. The roller portion 41 rolls in the width direction of the landing doorway 7 in contact with the sill-fixing portion 24, whereby the sill-movable portion 25 moves in the width direction of the landing doorway 7.
The sheave guide 44 is fixed to one of the sill fixing portion 24 and the sill movable portion 25. The pulley guide 44 includes a pulley guide roller portion 45 and a pulley guide support portion 46. The pulley guide roller portion 45 contacts the other of the sill fixing portion 24 and the sill movable portion 25 in the depth direction of the landing doorway 7.
When the guide rail 5 and the landing doorway 7 are relatively displaced in the width direction of the landing doorway 7, the members such as the door frame 21 connected to the sill movable section 25 move in the width direction of the landing doorway 7 as a whole following the guide rail 5, and the members fixed to the sill fixing section 24 do not move. Therefore, it is not necessary to displace the tunnel floor inside the landing tunnel 33 in the width direction of the landing doorway 7.
Next, a method of checking the tray 47 in the sill device 13 will be described with reference to fig. 18.
Fig. 18 is a diagram for explaining a method of checking a tray in a sill device in an elevator landing system according to embodiment 1.
The floor parting plate 42 is provided on the boundary side between the sill fixing portion 24 and the sill movable portion 25. The floor parting plate 42 is provided for parting from the building floor. The sill front plate 43 is fixed to the sill movable portion 25. A gap needs to be provided between the floor parting plate 42 and the sill front plate 43. Therefore, it is conceivable that dust or dirt enters the sill link mechanism 26 from the gap. Therefore, a tray 47 is provided below the gap.
The tray 47 is attached to the sill movable portion 25. When the floor parting plate 42 is removed, the tray 47 can be worked. In this state, the garbage and dust are removed.
The floor parting plate fixing bolt 49 is exposed on the upper surface of the floor parting plate 42. When the floor parting plate fixing bolts 49 are loosened and removed together with the floor parting plate 42, the tray 47 is exposed upward.
Next, a point inspection method using the pusher mechanism in the sill device will be described with reference to fig. 19.
Fig. 19 is a diagram for explaining a point detection method using a pusher mechanism in a sill device in an elevator landing system according to embodiment 1.
The pusher mechanism 48 is disposed below the sill movable portion 25. The urging mechanism 48 is provided so as to be able to enlarge the interval in the height direction between the sill fixing portion 24 and the sill movable portion 25.
According to embodiment 1 described above, the rail coupling mechanism 15 couples the member on the floor stand side and the member on the rail side to each other so as to be rotatable and slidable. Therefore, the structure can be applied to a quakeproof building with a simple structure.
Specifically, when the landing and the guide rail 5 are relatively displaced in the depth direction of the landing doorway 7, the landing-side door device 12 and the like are inclined in the depth direction of the landing doorway 7. Therefore, interference between the car 6 and the equipment at the landing can be avoided. As a result, in the elevator in which the car 6 engages with the door device 12 to open and close the door 11, the engaged state can be maintained.
The rail coupling mechanism 15 couples the door coupling beam 20 and the rail coupling beam 19 to each other so as to be rotatable and slidable. Therefore, even when the intervals between the pair of door coupling posts and the pair of rail coupling arms 18 are different, the assembly can be easily performed.
Further, when the guide rail 5 and the landing doorway 7 are relatively displaced in the depth direction of the landing doorway 7, the tunnel frame 29 follows the guide rail 5 via the tunnel frame coupling mechanism 32, the door coupling frame 14, the guide rail coupling mechanism 15, and the guide rail coupling frame 9 to incline in the depth direction of the landing doorway 7, and the 1 st opening 34 follows the tunnel frame 29 to cause the landing tunnel 33 to expand and contract in the depth direction of the doorway. Therefore, when the door frame 21 is inclined in the depth direction of the landing doorway 7, it is possible to suppress a change in the gap in the depth direction of the landing doorway 7 between the 1 st opening 34 of the landing doorway 33 and the door frame 21. As a result, interference between the landing doorway 33 and the door frame 21 and the presence of a person, an article, or the like between the landing doorway 33 and the door frame 21 can be suppressed.
The sill device 13 includes a sill fixing portion 24, a sill movable portion 25, and a sill coupling mechanism 26. Therefore, in the elevator installed in the building provided with the vibration-proof device 3, when the landing and the guide rail are relatively displaced due to an earthquake, it is possible to suppress a relative positional change of the car 6, the door device 12, the sill device 13, and the door 11 in the width direction of the doorway. As a result, it is possible to suppress people and articles from being pulled into the gap between the door of the car 6 and the door 11 of the landing. In an elevator in which the car 6 is engaged with the door device 12 at a landing to open and close the doors 11, the engaged state can be maintained.
The vertical frame 22 is coupled to the sill movable portion 25. Therefore, when the landing door device 12 and the landing door 11 move in the width direction of the landing doorway 7, relative displacement of the landing door 11 and the door frame 21 in the width direction of the doorway does not occur. As a result, it is possible to prevent people and articles from being pulled between the door 11 and the doorframe 21 of the landing.
The landing tunnel 33 connects the 1 st opening 34 and the 2 nd opening 35 so as to be extendable and retractable in the depth direction of the doorway of the landing. Therefore, when the door frame 21 is inclined in the depth direction of the landing doorway 7, it is possible to suppress a change in the gap in the depth direction of the landing doorway 7 between the 1 st opening 34 of the landing doorway 33 and the door frame 21. As a result, interference between the landing doorway 33 and the door frame 21 and the presence of a person or an article between the landing doorway 33 and the door frame 21 can be suppressed.
The sill connecting mechanism 26 includes a roller support portion 40 and a roller portion 41. Therefore, when the movable sill portion 25 moves in the width direction of the landing doorway 7, the movable sill portion 25 can be smoothly guided while suppressing vibration and noise.
The sill movable portion 25 includes a tray 47. Therefore, it is possible to suppress the occurrence of a failure of the sill coupling mechanism 26 due to the intrusion of dust, dirt, and the like into the inside of the sill device 13. Further, by performing the regular maintenance, the occurrence of a failure in the sill coupling mechanism 26 can be suppressed for a long period of time.
The sill device 13 is provided with a pusher mechanism 48. Therefore, maintenance and replacement of the sill coupling mechanism 26 can be easily performed.
