Description

Elevator device {ELEVATOR DEVICE}             

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a machine room of an elevator installed in a hoistway. More particularly, the present invention relates to an elevator apparatus capable of reducing the installation space and consequently the hoistway.

9 is a cross-sectional view of a hoistway showing a conventional elevator apparatus. The car 5 moves up and down in the hoistway 1 extending in the vertical direction. The machine room 2 is provided on the hoistway 1. In the machine room 2, the winch 3 which raises and lowers the car 5, and the control panel 4 which controls this winch 3 are provided.

A rope (not shown) is wound around the winch machine 3, one side of which is engaged with the car 5 to lift the car 5, and the other is connected to the counterweight 6.

Conventionally, as the machine room 2a is indicated by the broken line in FIG. 9 for the purpose of reducing the height of the hoistway 1 including the machine room 2 and reducing the construction cost of the machine room 2, the hoistway as the machine room 2a. It is proposed to arrange inside (1).

In the machine room 2a, a winch machine 3a and a control panel 4a are similarly provided.

By the way, in an elevator apparatus, a maintenance worker rides on the ceiling of the car 5, and many maintenance work is performed in many cases. For this reason, a space of a predetermined height is required between the ceiling of the car 5 and the ceiling of the hoistway 1.

That is, a predetermined dimension (hereinafter referred to as an overhead dimension) is required between the ceiling of the car 5 stopped on the uppermost floor and the ceiling of the hoistway 1 (or the obstacle from the car 5 to the upper obstacle). Done.

The overhead dimension when the machine room 2 is on the hoistway 1 is H1 shown in the drawing, and the overhead dimension when the machine room 2a is formed in the hoistway 1 with a broken line is H2. Since H1 and H2 actually need about the same length, even if the machine room 2a is installed only in the hoistway 1, the height H3 of the hoistway 1 including the machine room cannot be lowered.

In addition, although it is conceivable to install the machine room in the narrow space between the car 5 and the wall of the hoistway 1 in the hoistway 1, the machine room is prescribed for repairing the winch 3 or the control panel 4. The floor area and the maintenance space of the building were required, and this was a problem because the volume of the machine room was increased and the effective use of the space in the building was hampered.

Moreover, the proposal which arrange | positions a hoisting machine and a control panel directly in the hoistway 1 as shown by Unexamined-Japanese-Patent No. 2593288 is also proposed. Since there was no machine room, the workability was very bad in the maintenance work.
