- the emergency elevator system includes a fireproof divided hoistway, a device storage box body which is attached to an appropriate location of the hoistway higher than a pit of the hoistway and on which a waterproof treatment is performed, and device waterproof storage means for storing either or both of the elevator control device and the hoisting machine in the device storage box and prevents water immersion.
- a hoistway dimension increases.
- a ceiling thickness of the car increases, and a distance (hereinafter, referred to as OH dimension) from an uppermost floor of the building to a ceiling of the building also increases.
- the pit device is disposed at a height of more than 1 m from a pit bottom of the hoistway in compliance with a fire operation standard, there is a problem that the hoistway dimension needs to be increased in order to avoid interference between the pit device and the car.
- PTL 1 described above describes the emergency elevator system for avoiding the water immersion of the elevator control device and the hoisting machine in the hoistway during fire fighting in case of fire in the building, but does not describe any solution to the problem that the OH dimension becomes large or the hoistway dimension needs to be significantly increased.
- the present invention has been made in view of the above points, and an object of the present invention is to provide an elevator system capable of avoiding interference between a pit device and a car without significantly increasing a hoistway dimension even though a car of an elevator includes an evacuation ladder and a pit device is installed in a hoistway pit of the elevator.
- an elevator system in which a pit device is installed on a pit wall surface of a hoistway along which a car of an elevator moves up and down and an evacuation ladder is installed on a side plate of the car facing the pit wall surface of the hoistway on which the pit device is installed.
- the pit device and the evacuation ladder are installed at positions not overlapping as viewed from a plan or at positions different from each other.
- the present invention it is possible to avoid interference between the pit device and the car without significantly increasing the hoistway dimension even though the car of the elevator includes the evacuation ladder and the pit device is installed in the hoistway pit of the elevator.
- FIG. 1 shows a schematic configuration of an elevator apparatus 100 in a first embodiment of the elevator system of the present invention.
- the elevator apparatus 100 includes a hoistway 1 that communicatively connects each floor of a building 2, a plurality of landing places 2A provided on floors of the building 2, and a car 4 that moves in the hoistway 1 and stops at each landing place 2A, and each landing place 2A is communicatively connected with the car 4 through a car entrance 4A.
- the car 4 is connected to one end of a main rope (not shown) and is suspended in the hoistway 1, and a counterweight 5 balanced with a weight of the car 4 is connected to the other end of the main rope.
- a hoisting machine 3 that winds up the main rope and a control panel (not illustrated) that controls an operation of the hoisting machine 3 are installed above the-hoistway 1.
- the counterweight-side guide rail 9 is fixed to a wall surface 1A of the hoistway 1 via a first rail bracket 10 by fastening means 16a including a bolt and a nut
- the counterweight-side guide rail 8 and the car-side guide rail 7 are fixed to the wall surface 1A of the hoistway 1 via a second rail bracket 11 by fastening means 16b
- the car-side guide rail 6 is fixed to the wall surface 1A of the hoistway 1 via a third rail bracket 12 by fastening means 16c.
- pit devices such as an interphone 21, a control station switch 22, a bell 23, a brake release switch 24, and a buzzer 25 are installed on a wall surface 20a of a pit 20 of the hoistway 1 in which the car 4 moves up and down, and an evacuation space 27 for evacuating when a worker needs to evacuate for some reason is provided in a pit bottom portion 20b of the hoistway 1.
- Reference sign 26 denotes a pit junction box, and reference sign 33 denotes a rail bracket.
- an evacuation ladder 30 is installed on a side plate 4a of the car 4 facing the wall surface 20a of the pit 20 of the hoistway 1 in which the pit devices such as the interphone 21, the control station switch 22, the bell 23, the brake release switch 24, and the buzzer 25 are installed, and the pit devices such as the interphone 21, the control station switch 22, the bell 23, the brake release switch 24, and the buzzer 25 described above and the evacuation ladder 30 are installed at positions not overlapping or are installed at different positions as viewed from a plane (see FIG. 5 ).
- the above-described evacuation ladder 30 is stored in a ladder storage portion 32 provided on the side plate 4a of the car 4.
- the evacuation space 27 for' the worker is provided on the pit bottom portion 20b of the hoistway 1, but the pit devices such as the interphone 21, the control station switch 22, the bell 23, the brake release switch 24, and the buzzer 25 are installed above the evacuation space 27.
- the interphone 21 and the control station switch 22 are detachably held by a pit control station housing 28 detachably installed on the wall surface 20a of the pit 20 outside the evacuation space 27.
- the interphone 21 and/or the control station switch 22 is removed from the pit control station housing 28 and is moved to the evacuation space 27, and the interphone 21 and/or the control station switch 22 is operated in the evacuation space 27.
- the interphone 21 and the control station switch 22 are provided side by side in the pit control station housing 28, the interphone 21 is held with an operation unit positioned on a front side with respect to the pit control station housing 28, and the control station switch 22 is held with an operation unit positioned on a right side with respect to the pit control station housing 28.
- the protrusion of the evacuation ladder 30 installed on the side plate 4a of the car 4 and the protrusions of the pit devices such as the interphone 21, the control station switch 22, the bell 23, the brake release switch 24, and the buzzer 25 do not interfere with each other while increases in a width dimension, a pit depth, and an OH dimension of the hoistway 1 is suppressed to the minimum, and it is possible to utilize mutually effective spaces.
- the car 4 includes the evacuation ladder 30 and the pit devices such as the interphone 21, the control station switch 22, the bell 23, the brake release switch 24, and the buzzer 25 are installed in the pit 20 of the hoistway 1, it is possible to avoid interference between the pit devices such as the interphone 21, the control station switch 22, the bell 23, the brake release switch 24, and the buzzer 25 and the car 4 without significantly increasing the dimensions of the hoistway 1.
- the interphone 21 or the control station switch 22 can be moved simply by removing the interphone or the control station switch from the pit control station housing 28, it is possible to cope with the same work time as the current work time.
