Description

TECHNICAL FIELD The present invention relates to a temporary elevator control panel used when reforming an existing elevator.

[Conventional technology]

With regard to the performance of modern elevators, the adoption of electronic technology has led to significant improvements in power savings, improved riding comfort and safety due to improved control, and the elevator's design has also become a modern design that is important as a comfortable transportation facility. Has been done.

On the other hand, the old buildings built 10 years ago have been refurbished in line with the modern feeling, and the image is improved, but the elevators installed in these buildings have the same function as the old style. Is usually used in the design,
Users are demanding a fundamental improvement in elevator performance.

However, in order to satisfy such improvements in the performance and design of the elevator, the entire elevator must be modified, which requires a long time from the removal of existing parts of the elevator to the installation of new equipment. I had to stop the elevator in the meantime.

During this time, the user cannot use the elevator,
There is a demand for maximum reduction of the suspension period. In the case of a residential elevator or an elevator provided only in one office, there is a strong demand for a shorter suspension period.

Looking at the suspension period in units of one day, from 10 o'clock in one day
Elevators are relatively infrequently used during the hours of 16:00, and it is acceptable to stop during this time.
When renewing a residential elevator, construction that causes noise during the sleeping hours is not allowed,
It is desirable to keep the elevator in a condition that it can be operated at other times except 16:00.

As described above, Japanese Patent Laid-Open No. 61-55079 has already been proposed as a method of stopping the elevator only during a limited time period and performing work such as renewal. Therefore, the method described in this publication will be described with reference to FIGS. 3 and 4.

In the figure, (1) is a hoistway, (2) is a machine room provided above the hoistway (1), and (3) is a winding having a net wheel (5) arranged on a machine base (4).

The other end of the main rope is connected to the counterweight (8), and the hoist (30) moves the car (8) up and down at a speed of 30 to 45 m / min.

Thus, the temporary hoisting machine (30) is controlled by the control board (60) having the control circuit shown in FIG. 4 to raise and lower the car (7).

That is, in FIG. 4, (300) is an existing call button and (301

Since the control circuit described above is provided, when the call button (300) is pressed, the corresponding call is registered. If the call for the first floor (111) is registered, the relay contact (311S) is closed. Then press the descent start button (334) to contactor (404S)
Is energized to close the normally open contact (4041S) and close the contactor (4041S).

S) is closed, (+)-(411S)-(311S)-(405S)
-(-) Circuit is formed and the stop relay (405S) is energized. By energizing the stop relay (405S), the normally closed contact (4053S) is opened and the contactor (404S) is deenergized. The hoisting machine (30) is deenergized by deactivating the contactor (404S), and the car (7) is stopped on the first floor (111). Therefore,
By installing the temporary elevator, the car (7) can be moved up and down the first floor to the seventh floor by the temporary hoisting machine (30) regardless of the equipment installed in the machine room (2). Therefore, the equipment in the machine room (2) and the new cage (7)
Until installation, the temporary elevator can be used, and the service can be provided to the users' flights without significantly lowering the service. Further, the temporary elevator can be installed and removed at night when the frequency of use is low, so that the lifting service for the user can be maintained.

[Problems to be Solved by the Invention]

However, there is not enough space to install the temporary control panel (60) on the temporary machine base (40), and it may be blocked by a temporary enclosure (not shown) in order to extend to the landing on the 9th floor. There were many. Therefore, when the temporary elevator is operated, there is a problem that the operation sound of the contactor (404S) mounted on the control panel (60) resonates and becomes annoying to the elevator user.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a temporary elevator control panel capable of suppressing noise in a landing during operation of the temporary elevator.

[Means for Solving the Problems]

The temporary elevator control panel of the present invention has the first control panel installed on the floor of the hall and at least the contactor, and is located on the temporary machine base in the hoistway and more than the position of the door of the hall. And a second control panel installed inside and connected to the first control panel.

[Work]

According to the present invention, the part having the contactor can be installed on the machine base temporarily installed in the hoistway.

〔Example〕

Based on the embodiments shown in FIG. 1 and FIG. 2, the same or corresponding parts as in the prior art will be designated by the same reference numerals, and the characteristics of the present invention will be mainly described.

As shown in FIG. 1, the temporary elevator control panel (60) of the present embodiment has a lift contactor (403S) that becomes a noise source during operation.
And the descending contactor (404S) are separated from the main body,
As shown in FIG. 2, only the contactors (403S) and (404S) are installed in the hoistway (1) and the other main body portions are temporarily enclosed.

That is, as in the present embodiment, the ascending contactor (403S) and the descending contactor (404S) are independent of each other, and the main body is connected to the first control panel (60A), the contactors (403S) and (404S). If the second control panel (60B) is installed, the second control panel (60B) is installed on the machine base (40) temporarily installed in the hoistway (1), and the first control panel (60A) with less noise is installed. It will be possible to install it in the temporary enclosure (16) that protrudes to the 9th floor.

Thus, even when the user uses the elevator during the work such as the renewal of the elevator, the second control panel (60
Noise generated from B) is suppressed in the hoistway (1) and the floor (1)
Since it is further suppressed by the temporary enclosure (16) of 19), the noise received by the user will be significantly suppressed as a result.

Further, in the above embodiment, the floor (119) side end of the temporary machine base (40) is set as described in JP-A-61-64687.
If it is located inside the landing door (10), the wiring connecting the first control panel (60A) and the second control panel (60B) can be left, and the door (10) can be almost closed, and noise can be reduced. Can be further reduced.

〔The invention's effect〕

As described above, according to the temporary elevator control panel of the present invention, the second control panel having the contactor as a noise source is divided into the first control panel and the second control panel, so that the space of the temporary machine base is reduced. Even when is small, the contactor can be installed inside the position of the door in the hall, and noise in the hall can be significantly suppressed during operation of the temporary elevator.
