Abstract

(57) [Summary] The present invention can reduce the plane area of a hoistway or improve maintainability. SOLUTION: In order to make a part of a hoisting machine 14 composed of a rotor protrude above a passage of a car 2 and avoid a projecting portion of the hoisting machine 14, a concave portion 17 is formed in an upper part of the car 2.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator for carrying cargo between floors.

[0002]

2. Description of the Related Art Generally, in a rope type elevator,
Form a hoistway in the building, place a counterweight in the hoistway, and place a machine room on the building,
A hoist and a control panel were provided in this machine room.

[0003] As described above, since the machine room is located on the building, there is a problem of sunshine. In such a case, the hydraulic elevator is mainly installed.

However, in the case of a hydraulic elevator, there is a problem that the speed cannot be increased due to its characteristics.

[0005] For this reason, recently, as disclosed in Japanese Patent Application Laid-Open No. 7-10434, a hoist comprising a disc-shaped rotor has been used.
An arrangement has been proposed which is arranged above the car passage at the top of the hoistway and between the hoistway wall.

[0006]

In the above-mentioned proposal, the hoist is disposed in the space between the hoistway above the car and the hoistway wall, so that the hoistway plane area can be further reduced. There was a problem that it could not be done.

There is also a problem that the gap between the hoist and the hoistway wall is too narrow to maintain.

An object of the present invention is to propose an elevator that can reduce the hoistway plane area or improve maintainability.

[0009]

SUMMARY OF THE INVENTION The object of the present invention is to provide a hoist comprising a disk-shaped rotor above a hoistway and in a space between hoistway walls. In an elevator in which a provided car and a counterweight are lifted and lowered, a part of the hoist is projected above a car passage, and a recess is formed in an upper part of the car in order to avoid the protrusion of the hoist. This is achieved by:

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an overall schematic diagram of an elevator according to an embodiment of the present invention.

In FIG. 1, a car 2 is mounted on a wall of a hoistway 1.
Guide rail 3 and counterweight 4 for guiding cars
Is fixed by brackets 6 and 7, and these guide rails 3 and 5 extend from the bottom of the hoistway 1 to the vicinity of the ceiling 8.
Each of the pulleys 9,
A rope 11 is wound via a cable 10. An end 12 of the rope 11 is fixed to a rope end 13 fixed to an upper portion of the hoistway 1, and a pulley 9 at a lower portion of the car 2 is provided.
And wound around a hoisting machine 14 composed of a disc-shaped rotor supported between the counterweight guide rails 5 at the upper part of the hoistway 1, and then wound around the pulley 10 of the counterweight 4. The other end 16 of the rope 11 is fixed to another rope end 15 fixed above the hoistway 1. Therefore, the car 2 is configured to move up and down through driving of the hoisting machine 14 composed of a disk-shaped rotor.

Further, a hoisting machine 14 comprising a disk-shaped rotor
Are supported between the counterweight guide rails 5, and the hoist 14 protrudes above the passage of the car 2. Reference numeral 17 denotes a concave portion provided at the upper part of the car for pulling out the protrusion of the hoisting machine 14.

In the elevator constructed as described above, the hoisting machine 14 composed of a rotor is protruded above the passage of the car 2 and the recess 17 is provided at the upper part of the car 2, so that the elevator 1 The flat area can be reduced, and the maintainability can be improved.

[0015]

According to the present invention, the plane area of the hoistway can be reduced, or the maintainability can be improved.
