Abstract

PROBLEM TO BE SOLVED: To easily convey and carry various panels into a hoistway by independently accommodating an incoming panel, a resistance box and a housing panel in a hoistway, and mounting the panels on a side wall part while horizontally dispersing the same. SOLUTION: An incoming panel NF for receiving the electric power for driving a car 4 from the external is mounted on a side wall 2 of a pit located at an outlet side with respect to a rail for car 5 at a height where a worker can touch the panel by his hand from a pit floor surface 3a. A resistance box RBa storing a resistor consuming the power generated in the elevation control of the car 4 is mounted on the side wall 2 beside the incoming panel NF on a position horizontally separated in the depth direction through the rail for car 5. Further a control panel CBa for controlling the elevation of the car is mounted on the side wall 2 at a position opposite to the incoming panel NF. By independently forming and mounting the incoming panel NF, the resistance box RBa and the control panel CBa while horizontally dispersing the same, they can be easily conveyed and sent into the hoistway 1.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator hoistway on which a control panel and the like are installed.

[0002]

2. Description of the Related Art Normally, a control panel and the like are housed in a machine room provided at the top of a hoistway together with a hoist. However, when the machine room is installed on the top, the roof of the machine room part protrudes one step, and there is a dislike of damaging the appearance of the whole building. From the viewpoint of improvement and space saving, a hoisting machine, a control panel, and the like are installed in the hoistway to omit the machine room at the top of the hoistway. As described above, a conventional example of an elevator hoistway provided with a control panel and the like is disclosed in Japanese Patent Publication No. 7-37380.
Japanese Patent Publication No. 8 (KOKAI) No. 8 discloses a method. 6 to 8 show the same type as that described in the above patent publication. In the figure, a car 4 is stored in a hoistway 1, and this car 4 is hung by a main rope 6 locked to an upper beam 3c, and a car rail 5
Guided to go up and down. A balance weight 7 is locked to the other end of the main rope 6, and is guided by the weight rail 8 to move up and down in a slippery manner. Basket 4 is the first floor landing F1-4
Stop at the floor F4, etc. and enter the car door 4a and the landing door F1D.
The F4D is opened and closed to be used for elevating the user. Also,
The control device CB is a comprehensive device including a control panel, in which a power receiving panel for receiving power from the outside, a control panel for controlling the elevation of the car 4, and further a relay terminal and the like are integrally incorporated. . This control device CB is attached to the side wall 2 of the hoistway 1, and further, a resistor box RB that consumes electric power generated by control is placed on the top.

[0003]

By the way, in the hoistway 1, since the maximum number of cars 4 is stored for effective use of the indoor space, the empty space is usually limited as shown in FIG. Become. For this reason, when trying to install in this empty space, the control device CB had to be thin. In addition, since the car rails 5 are attached to the left and right side walls 2 of the hoistway 1 over substantially the entire height of the hoistway 1, the width of the control device CB is also limited. For this reason, the control device CB had to be thin and vertically long as shown in FIGS. When the control device CB has such a structure, there is a problem that the strength is unstable, and in addition, it is inconvenient and time-consuming to transport a long object and carry it into the hoistway 1. In addition, the maintenance and inspection work is inevitably performed on the ceiling upper surface 4b of the car 4, but since the control devices are scattered vertically, the inspection of all the control devices is performed while the car 4 is stopped. Can't do it. For this reason, it is necessary to perform the inspection work while moving the car 4 up and down, which is inefficient and inconvenient for grasping the entire operation.

[0004] The present invention has been made to solve such a problem, and an elevator hoistway in which a power receiving panel, a resistor box, and a control panel (hereinafter, also referred to as panels) are stored. It is an object of the present invention to provide an elevator hoistway to which the above-mentioned panels are attached so that the above-mentioned panels can be conveniently transported and carried into the hoistway, and can be easily maintained and inspected.

[0005]

The elevator hoistway according to the present application has a power receiving panel, a resistor box, and a control panel, which are conventionally integrally configured as a control device, each of which is separately configured, and They are arranged so as to be dispersed in the horizontal direction.

In the elevator hoistway according to the present application, the power receiving panel, the resistor box, and the control panel are dispersed in a horizontal direction at a height that can be maintained from the pit floor of the hoistway. Is attached to the side wall of the vehicle.

Further, in the elevator hoistway according to this application, the power receiving panel, the resistor box, and the control panel stop the car at a predetermined position, and each of the cars receives the car from the upper surface while the stopped state is maintained. And is mounted on the side wall of the hoistway while being distributed horizontally at a height that can be maintained.
