Abstract

PURPOSE:To reduce inconvenience when a set of elevator devices is replaced with a new product by operating the elevator by a specialized operator only during operation of replacing a control panel and a cage, and operation of replacing tower-switches, etc., and performing routine operation during other operations. CONSTITUTION:When a set of elevator devices is replaced with a new device, the construction period is divided as follows: the first stage operation including carrying-in of new equipment and materials, check, etc., the second stage operation of temporary wiring of tower-wires, temporary wiring of the ceiling of a machine room, etc., the third stage operation of replacing an existing winder with a new winder, etc., and the fourth stage operations including replacement of the new and old parts related to the machine room, works related to a cage, etc. During these operations, routine operation of the elevator is performed. But, during the fourth stage operation and fifth stage operations such as adjustment of door machine wiring, replacement of tower-switches, etc., the elevator is operated by a specialized operator. During operations of replacement, etc. of indicators and doors at respective stories after the fifth stage operation, routine operation of the elevator is performed again. Inconvenient period of time during the construction period except during the operations can thus be reduced to a minimum.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a method for modifying an elevator, and in particular to a method for modifying an elevator that allows the modification of the elevator to be carried out without continuously stopping the elevator for a long period of time. Regarding construction methods.

[Conventional technology]

In general, elevators, such as elevators, have advanced technology levels such as high speed, power saving, and control intelligence.

The product value is determined by a comprehensive evaluation based on a variety of items, including safety and design. Furthermore, with the adoption of electronic technology, recent elevators have significantly improved their service functions and have become more in line with modern sensibilities in terms of design, resulting in their widespread use as safe and comfortable transportation equipment.

Figures 3 to 5 are explanatory diagrams showing the structure of a part of the existing elevator. Figure 3 is a side view showing the machine room, Figure 4 is a front view showing the entrance/exit part, and Figure 5 is an explanatory view showing the structure of a part of the existing elevator. It is an AA sectional view of the figure. As shown in Fig. 3, the hoisting machine 3 includes an electric motor 1 and a reducer 2.
It is installed on a machine beam 4 fixed with anchor bolts 8b on a machine room floor 6 that separates a hoistway (not shown) and a machine room 5. Further, the machine beam 4 has its tip 4a embedded in the machine room 5 to improve its strength, and the entire periphery of the machine beam 4 is fixed with cinder concrete 7.

In addition, the control panel 9 provided as other main equipment is a pull box 8 fixed on the machine room floor 6 with anchor bolts 8b.
It is installed by bolts 8a. The hoisting machine 3 and the control panel 9 are wired through a pipe Ml, and the car (not shown), the landing device (not shown), and the control panel 9 are wired through a pipe C1. Note that the pipes are buried in cinder concrete 7 so as not to protrude above the machine room floor 6.

In addition, in the entrance/exit section shown in FIGS. 4 and 5, after installing the entrance/exit frame 13 consisting of the entrance/exit door stop frame 13c, entrance/exit door bag frame 13b, and entrance/exit upper frame 13a on the rough wall 15, for fire prevention purposes, Fill the back side of the doorway frame 3 with mortar 16,
An interior material 18 is attached to the surface of the rough wall 15. A hole for the hall display 14 is pre-drilled in the interior material 18 and the rough wall 15, and the hall display 14 is installed by fitting the hall display case 14b into this hole. Further, a door hanging device (not shown) is fixed to a rough wall 5 on the hoistway side above the entrance with an anchor bolt 8b, and finally a door 17 is hung to form a landing 19.

By the way, for example, the elevator installed around 10am,
There is a feeling that the building has been left behind as the image of the building has been renewed through renovation work to match the sensibilities of the times, and elevator users are demanding a fundamental improvement in performance. This level-up includes updating the car design from the viewpoint of appearance, the car operating panel and display device, and the design of each floor display, as well as improving the reliability of equipment such as hoisting machines. These include replacement, control changes to improve driving performance with a focus on riding comfort and landing accuracy, and the addition of additional specifications such as improved earthquake resistance.
In the end, it's likely to be a fairly large-scale remodel.

FIG. 6 is an explanatory diagram showing a conventional method of remodeling work carried out inside the shell when carrying out such large-scale remodeling. As shown in Figure 6, the remodeling work generally begins with the removal of the old parts of the hoistway and machine room, the installation of new parts of the machine room, the wiring of the hoistway and machine room piping, and the entrances and exits of each floor. removal and installation, assembly of new cages, installation of new parts inside the tower, wiring of equipment in the machine room, inside the hoistway.

The wiring around the car is connected, and the final step is a trial run and adjustments. Such large-scale remodeling work requires more man-hours than installing a new elevator.

For example, in the machine room shown in Fig. 3, the existing control panel 9, hoisting machine 3, and piping C1, Ml are removed and replaced with new ones by chiseling and backfilling with cinder concrete 7. Work occurs.

Furthermore, since the tip end 4a of the existing machine beam 4 is embedded in the machine room wall 5, the building body may sag. Furthermore, in the entrance/exit section shown in Figures 4 and 5, the entrance/exit frame 131, the case 14b of the hall indicator, etc. are embedded in the building, so lifting work is required in the same way as in the machine room. ing.

For this reason, conventional methods have been proposed to reduce the overall construction period and simplify the work method.
The one described in Japanese Patent No. 45099 has been proposed. This prior art describes a method of attaching tower equipment using a car frame. Further, as a method focusing on dividing the construction period, for example, a method described in Japanese Patent Application Laid-open No. 7180/1983 has been proposed. This conventional technology includes
In the first period, the car operation panel and landing display were replaced, and in the second period,
While using the existing door body and door machine, the car will be replaced, the control panel will be replaced in the third stage, the hoisting machine will be replaced in the fourth stage, and the car door, landing door, and door machine will be replaced in the fifth stage. A method is shown in which the first and second periods are set as the first stage, and a method in which the third to fifth periods are set as the second stage.

[Problem to be solved by the invention]

In the prior art disclosed in the above-mentioned Japanese Patent Laid-Open No. 52-45099, it is necessary to continuously stop the elevator for a long period of time in a building that is in operation.

Considering the current situation where elevators are indispensable as vertical delivery equipment in building facilities, continuously stopping elevators for a long period of time, for example, one month, can cause a great deal of damage to building users or residents. This is not desirable as it causes inconvenience.

This is particularly noticeable in relatively small office buildings or apartment buildings where only one elevator is installed.

Moreover, in the prior art shown in the above-mentioned Japanese Patent Application Laid-Open No. 61-7180, in the first, second, and fifth periods,
Since the car-related modifications are carried out, the work is duplicated, and from this point of view it is difficult to expect improvement in work efficiency.

The purpose of the present invention has been made in view of the actual situation in the prior art described above.The purpose of the present invention is to subdivide the work period so that the elevator operation time can be provided in a day without requiring lifting work when remodeling the elevator. To provide a method for remodeling an elevator so as to reduce inconvenience to users.

[Means to solve the problem]

In order to achieve the above object, the present invention includes a first stage work of drilling a machine room hole for lowering at least a control panel, a hoisting machine, a car, and a tower inner line among tower internal parts, and a tower Phase 2 work involves temporary wiring of extension lines, Phase 4 work involves replacing control panels and cages, Phase 5 work involves replacing switches inside the tower, and replacing doors on each floor, depending on the number of floors in the building. The construction is such that the elevator is divided into 6th period work in which replacement is required, each work takes 8 to 18 hours, and the elevator can be returned to operating condition without fail.

[Effect]

The present invention, configured as described above, allows large-scale remodeling work to be carried out without duplication of related work and without requiring chisel work, and in the first to sixth stages. By subdividing, the working time is 8 hours to 18 hours.
Since the work can be done in a short time and the elevator can be used after the work is completed, the elevator does not have to stop continuously for a long period of time, which reduces the inconvenience to elevator users.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG.

Figure 1 shows the basic steps in the elevator remodeling method, and the work is divided so that each work step can be completed in a maximum of 8 hours.
For example, by setting the work time to nighttime when there are fewer people using elevators, elevators can be used during the day.

The first phase of work includes drilling holes in the machine room for wiring inside the tower, which will be carried out in the second phase, checking existing lines to reuse existing lines such as power lines, and carrying in and checking parts necessary for elevator modification. The work can be completed in about 8 hours. The elevator will be available for use once the work is complete.

Next, the second stage of work will include installing ceiling piping in the machine room, the control panel to be installed in the fourth stage, the switches in the tower that will be replaced from the fifth stage, and the tower internal wire that runs between each dark indicator. The board wiring is laid out, and the work can be completed in about 8 hours.

Next, in the third stage, the hoisting stage will include removal, installation, and rope replacement. At this stage, since the hoisting machine will be new, the control panel will be modified. The work can be completed in about 10 hours.

Next, in the fourth period, machine room-related processing and car-related processing are performed. In other words, regarding the machine room, the control panel and speed governor will be removed, a new control panel and speed governor will be installed, and the wiring inside the control panel will be connected. Additionally, the floor selection machine will be removed as it will become a control panel equipped with a microcomputer and will no longer be necessary. In addition, in relation to the car, after lifting and lowering the car, the car is dismantled and reassembled, and the wiring around the car is done. Furthermore, since the machine room and the inside of the tower are separated by the machine room floor, the above-mentioned machine room-related processing and cage-related processing are performed simultaneously, and one work hour is 8 hours of labor. It is possible to complete the process at a certain level. At this time, priority is given to making the elevator operable, and the wiring and adjustment of the door machine will be done in the fifth stage, so the elevator will be operated by a professional driver and the doors will be opened and closed manually.

Next, as mentioned above, the fifth stage will include door machine wiring and adjustment, as well as replacing switches inside the tower and removing the existing tower wiring, and the work can be completed in about 8 hours.

Finally, in the 6th period, the work will be divided into sections according to the number of floors to replace the display at the entrance, the door, and the door hanging device so that the work will take 8 hours.

As mentioned above, the work time to be divided and carried out can be completed in 8 to 18 hours, and by allocating the work time to night time, for example, it becomes possible to operate the elevator during the day.
During the work period, elevators will not be stopped all day long, which will eliminate the inconvenience for customers.

Although this embodiment does not require chisel work, this will be explained next by citing processing related to the machine room.

FIG. 2 is a side view showing the machine room of an elevator to which the method of this embodiment is applied.

The newly installed hoist 3a consists of a newly installed electric motor 1a and a newly installed reduction gear 2a. This newly installed hoisting machine 3a, due to technological advances,
Generally, the entire hoisting machine 3 is smaller than the existing hoisting machine 3. Therefore, in this embodiment, the machine bases 12a, 12b are attached to the existing machine beam 4 without performing chisel work.
and a new hoisting machine 3a. Also, the newly installed control panel 9a is also smaller, but there is a spacer 9 between the existing pull box 8 and the new control panel 9a.
Insert b and perform installation. In addition, the newly installed control panel 9a, the newly installed car C' (not shown), and the signal wires (not shown) of the newly installed hall equipment on each floor can be connected to the ceiling 11 without installing the cinder concrete 7, that is, with the brackets 11
It is arranged by the ceiling piping C2 installed at o. Note that the existing piping M1 is often used as the power line for the newly installed electric machine 1a, so in such a case, the existing piping M1 is used as is and only the power line is replaced with a new one. In addition, existing piping M
1 cannot be used, another ceiling pipe, similar to the ceiling pipe C2, is passed through to the ceiling directly above the newly installed electric motor 1a, and wiring is performed. If you perform machine room-related processing in this way,
Chipping work can be avoided.

In addition, regarding the landing entrance/exit, we will reuse the existing ones for the landing display case and entrance/exit frame 1 landing sill, etc., and replace the landing display, door hanging device, and door, thereby making it easier to lift the building. It's unnecessary. Furthermore, the entrance/exit frames and landing sills can be refreshed to almost the same extent as new ones by repainting or polishing. In addition, due to technological advances, the landing display and door hanging device are equipped with electronic components, ensuring reliability and
Replace with one with improved safety. As for the door, the installation dimensions are different from the new door hanging device, and on-site processing is required, so it will be replaced.

In the embodiment configured in this way, the work process consists of the first phase of drilling holes in one machine room and checking the existing lines, the second phase of installing ceiling piping in the first machine room, and temporarily wiring the lines inside the tower.
3rd stage work to remove the hoisting machine and install a new one, 4th stage work to replace the control panel and car, and 5th stage work to do door machine wiring, adjustment, and replace switches in the tower.
The work will be divided into the 6th stage and the 6th stage, in which each blackout indicator, door on each floor, etc. will be replaced according to the number of floors, and each work will be completed in 8 to 18 hours, as no chiseling work is required. This eliminates the need for elevators to stop all day long and provides a stable operating condition.

Although it is preferable to perform each task continuously, it is also possible to set intervals between each task, and depending on the customer's request,
For example, if a work period of around one week is available, such as during summer vacation, the first to sixth periods can be carried out consecutively.

〔Effect of the invention〕

According to the present invention, since it is configured as explained above, there is no need for chisel work during remodeling, and the elevator does not stop all day long, so the elevator can be used after the work is completed, and only one elevator is used. In office buildings and housing complexes where the system is installed, users will no longer be forced to inconvenience themselves.
