Description

Description: TECHNICAL FIELD The present invention relates to an improvement in a wiring method of a wiring device provided in a machine room above an elevator hoistway.

[Conventional technology]

The equipment in the machine room above the elevator hoistway will be described with reference to FIG. (1) is a machine room provided above the elevator hoistway (5), (1a) is the floor of the machine room (1), (1b) is cinder concrete laid on the upper surface of the floor (1a), ( 2a) stands on this cinder concrete (1b) and is an existing control panel for controlling an elevator (not shown), (3) is installed on the cinder concrete (1b) and lifts the elevator A hoisting machine, (3a) is a hoisting motor that drives this hoisting machine (3),
(4) is an existing wiring device that connects the existing control panel (2a) and the hoisting motor (3a), and the floor duct or floor pipe with the built-in connection wiring is embedded in the cinder concrete (1b). . Further, in the machine room (1), in addition to the above-mentioned equipment, although not shown, a governor machine that adjusts the lifting speed of the elevator, a floor machine that adjusts the position of the elevator, and the like are provided. The entire equipment is controlled by the existing control panel (2a).

[Problems to be solved by the invention]

In the case of updating the elevator apparatus having the above machine room, there are the following problems. less than,
The three cases will be described separately.

(1) When updating an existing elevator device.

When updating an existing elevator system to a new elevator system (hereinafter also referred to as "renewal"), it is necessary to shorten the rest period of the existing elevator as much as possible and to shorten the installation work time of the new elevator system as much as possible. . Therefore, in order to shorten the downtime of the existing elevator and shorten the installation work time, at least the hoisting motor and the control are included in the wiring work for the new elevator device that is renewed during the operation of the existing elevator device. I would like to complete the wiring work with the board. Therefore, in general, the wiring for new installation is also laid in the floor duct of the existing wiring while the existing elevator equipment is in operation, and when the replacement of the machine room equipment is completed, it can be spliced to a new wiring system for a short period of time. I am able to renew after a break.

However, as the wiring device of the existing elevator device, generally, the floor duct or floor piping in the machine room is used, but in this existing floor duct or floor piping where wiring is already arranged inside, Furthermore, even if an attempt is made to insert wiring for a new elevator device, there is often no room for storage. Moreover, in recent years, since connectors are often used for splicing wiring, it is almost impossible to pass the wiring particularly in the case of a wiring device using piping. Further, in recent years, a microcomputer is used to control an elevator apparatus, but it is not preferable to pass both old and new wirings through the same floor duct or floor piping from the viewpoint of noise resistance.

By the way, if the floor duct or floor piping of the existing elevator equipment can be reused, and if the old wiring is not removed and the old wiring is not removed in order to shorten the work time, the same floor duct will not be removed. Among them, the old wiring and the new wiring are mixed with each other, which causes a disadvantage in maintenance. Further, in this case, the positional relationship between the wiring device such as the existing floor duct or floor piping and the control panel is limited, and it is difficult to temporarily connect the wiring to the newly installed control panel.

(2) When adding an elevator device.

In the case of adding an elevator device, if the wiring device in the room that describes the existing elevator device has a wiring storage capacity that anticipates future expansion elevators, no problem will occur in the case of this extension work, In general, there are few wiring devices that take such future expansion into consideration.
In such a case, shaving the concrete on the floor of the machine room to install the floor duct or floor piping has a problem that the building itself is in business and it is necessary to perform the construction by the soundless construction method. On the other hand, when the soundless construction method is not adopted, the working time is limited, which is not preferable in terms of shortening the working time. This point is the same as in the above-mentioned "when updating the existing elevator system".

(3) When newly installing a plurality of elevator devices.

In the case of newly installing a plurality of elevator devices, one of the elevator devices is for emergency use,
Or, when distinguishing from other elevator devices, such as when the control system is different, it is necessary to improve the workability of maintenance by using a wiring device different from that of other general elevator devices and using a separate system. However, the improvement has not been attempted in the past.

The present invention has been made to solve the above problems, and an object of the present invention is to obtain a wiring method in a machine room for an elevator that can be used as a separate wiring device for an elevator apparatus to be renewed or newly installed.

[Means for solving problems]

The wiring method in the elevator machine room according to the present invention is to install a new control panel separate from the control panel in the machine room where the control panel of the elevator apparatus is installed, and install the wiring device in the system of the control panel. Besides, it is separately provided as a system of the new control panel.

[Action]

In the present invention, since the wiring device is provided separately in two systems, the wiring work for the new wiring device can be continued even while the existing elevator is in operation.

〔Example〕

Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. The same members as those in FIG. 8 are designated by the same reference numerals and the description thereof will be omitted. FIG. 1 is a plan view of a machine room (1) showing a state of a wiring device in a machine room for an elevator during a renewal stage of an existing elevator apparatus according to a first embodiment of the present invention, and FIG. 2 is a plan view of FIG. 3 is a perspective view of the machine room (1) with a part of the machine room (1) omitted. Third
FIG. 4 is a cross-sectional view taken along the line AA in FIG. 1, and FIG. 5 is a detailed perspective view showing the state of the wiring device in the elevator machine room after the completion of the renovation of the existing elevator device.

The first embodiment is a case where an existing elevator system is renewed into a new elevator system. To explain this case, as shown in the figure, inside the machine room (1),
A control panel (2a) is installed which controls the hoisting machine (3), hoisting motor (3a) for the hoisting machine, elevator device, and is also connected to the hoisting motor (3a) by wiring. The control panel (2a) of this embodiment is an existing control panel. The existing wiring device (4) for connecting the existing control panel (2a) and the hoisting motor (3a) was embedded in the cinder concrete (1b) above the floor (1a) as shown in FIG. By the floor duct (4a) and the existing wiring (4c) arranged in the floor duct (4a), or as shown in FIG.
The floor wiring (4c) is embedded in the cinder concrete (1b) above the floor (1a), and is composed of the existing wiring (4c).

Next, the new control panel (21a) is installed at a predetermined place in the machine room (1), and the overhead duct (41b) is hung from the ceiling of the machine room (1) via a plurality of support members (41a). Set and fix. This overhead duct (41b) is installed in the new control panel (21
It is also connected and fixed to the ceiling plate (21b) of a) by the earthquake-proof fixing member (21c). Then, the wiring cable (41c) for the hoisting motor (3a) is arranged along the overhead duct (41b), and one end is connected to the new control panel (21a) by wiring, and each other is branched to each device. The ends are arranged in the vicinity of predetermined devices. The supporting member (41a), the overhead duct (41b), the wiring cables (41c) and (41d), and the earthquake-proof fixing member (21c) constitute a new wiring device (41). Next, after updating the hoisting motor (3a) from the existing one to the new one, the other end of the wiring cable (41c) is connected to the newly hoisting motor (3a) by wiring. Wiring cable (41d)
Wiring connection is also made in the same manner.

FIG. 6 is a sectional view corresponding to FIG. 3 showing a second embodiment of the present invention when the existing elevator device is renewed, and is an overhead duct (41) as a new wiring device.
Instead of using b), the case of using the floor duct (41e) is shown. That is, the floor duct (41e) is placed on the cinder concrete (1b) separately from the existing wiring device (4), and the wiring cable (41e) is placed in the floor duct (41e).
c) and (41d) are shown. The height of this floor duct (41e) is usually about 50 to 100 mm.
(41f) is a fixing member for fixing the on-floor duct (41e) to prevent movement, and this embodiment shows the case of mortar.

In addition, as a third embodiment (not shown), when the existing elevator device is renewed and the new control panel is installed again at the same position as the installation position of the existing control panel, the existing control is not performed. While operating the elevator equipment on the panel, install a new wiring device of a system different from the existing wiring device, and splice the new wiring into the new control panel that is temporarily placed, and install the new wiring to this new control panel. The wiring cable at the splicing part of the device may have some allowance so that the new control panel can be moved from the temporary placement position to the original installation position.

In the above-mentioned first to third embodiments, the connection portion of the wiring with the existing control panel (2a) and the hoisting motor (3a) of the existing wiring device (4) whose renewal has been completed is a part of the maintenance of the new elevator device. Partially cut, etc. so that no hindrance occurs, cover the opening of cinder concrete (1b) for floor duct (4a) or floor piping (4b), or repair with mortar, etc. Treatment is required. But,
The wiring part in the middle may be left as it is as long as it does not hinder.

As a fourth embodiment (not shown) of the present invention, even when an elevator device is additionally installed, similar to the first or second embodiment, the overhead duct (41b) or the floor duct (4).
A wiring device using 1e) may be provided separately.

FIG. 7 is a plan view corresponding to FIG. 1 showing a fifth embodiment of the present invention in which a plurality of new elevators are provided with a two-way wiring device in the elevator machine room (1). That is, as shown in the figure, a plurality of elevator devices (11) to
(14) is newly installed, and when the elevator device (14) among them is used for a special purpose, for example, as an emergency, and is distinguished from other general elevator devices (11) to (13), the general elevator devices (11) to If the floor duct (4a) is used for the wiring device (4) of (13), the overhead duct (41b) is used for the wiring device (41) of the emergency elevator device (special elevator device) (14).
May be used or vice versa. Further, the floor duct of the emergency elevator device may be installed at a position where it does not interfere with the floor ducts (4a) of the general elevator devices (11) to (13) (not shown). The emergency elevator device (14) is not limited to one, but may be two or more. Therefore, by adopting the configuration of this embodiment, the connection between the control panel (21a) for the emergency elevator device (14) and the hoisting motor (3a) becomes obvious, and the workability of maintenance is improved. It becomes possible, and it becomes possible to easily cope with the situation such that only the emergency elevator device (14) has a fire resistant structure to improve fire resistance performance.

Therefore, according to the present invention, as described above, when the existing elevator device is renewed, the restoration can be performed in a time close to the splicing of the wiring to the hoisting motor (3a), so that it is possible to shorten the idle period of the elevator. Become. In particular, recently, the WOS method (Without Scaffoud ... method without scaffolding) has become widespread, and even during renovation work, the control panel and hoisting motor can be connected to the wiring early so that the hoisting motor can be powered. If it is done, the wiring connection to the equipment in the hoistway and the landing indicator can be easily done by using the elevator car as the work floor.Therefore, early wiring connection of the equipment in the machine can shorten the installation work for renewal. It can be said that it is the key to the change.

Further, according to the present invention, when the existing elevator device is renewed, it is not necessary to take out and remove the wiring in the old wiring device (floor duct, floor piping, etc.). Therefore, the work time can be shortened by the amount not required to be removed, and the labor can be saved.Also, even when the existing elevator is in operation, the newly installed wiring device can be installed in the machine room as a separate route. The new control panel can be installed at the optimum position without being affected by the position.

By the way, when the overhead duct (41b) is used for the new wiring device (41), by connecting the overhead duct (41b) and the upper part of the new control panel (21a) through the seismic fixing member (21c). It is also possible to use it as an earthquake-proof fall stop.

Further, in the present invention, the existing floor duct or floor piping is also used as a means for laying the new wiring in addition to the old wiring, and the new and old wirings are separated from each other, so the work at the time of removing the existing wiring There is no need to color-code old and new wires for the purpose of checking the characteristics and continuity test, and it is not necessary to take extra consideration.

Further, according to the present invention, since it is not necessary to grind the concrete on the floor of the machine room, even in a building in operation, noise for construction does not occur or it is extremely small, so that the working time is limited. As a result, the work can be easily performed without receiving the work, and the work time can be shortened.

〔The invention's effect〕

As described above, according to the present invention, a new control panel is installed separately from the control panel in the machine room in which the control panel of the elevator system is installed, and the new control panel is installed near the ceiling of the machine room and the new control panel is installed. An overhead duct connected to the panel is provided, and a wiring device for new installation, which is arranged separately from the wiring device connected to the control panel, is connected via the overhead duct.

In addition, the wiring device for new installation is fixed on the floor surface of the machine room and is constructed by an on-floor duct having a height of about 50 mm to 100 mm and connected to the new control panel.

As a result, the effect of increasing the earthquake resistance of the new control panel by the overhead duct is obtained. Further, it is possible to improve the workability at the time of renewal and to distinguish the wiring device for a special elevator from a general elevator.
