Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a method for modifying a side-by-side elevator from a relay type to a microcomputer type.

[Prior Art] In general, an elevator is taking in a call button provided in each floor hall as a common signal, and a common circuit is provided between the control device and the hall call button.

The remodeling from the relay type to the microcomputer type in this adjoining elevator is mainly divided into a common circuit part between the control device and the hall call button, and a unit for each car between the car part and the car and the hall call button. For example, as shown in Japanese Patent Laid-Open No. 61-7180, a split replacement construction method is employed in which the elevator being remodeled is separated from the common circuit and the other elevator is operated. .

Fig. 2 is a process diagram of the conventional construction method, and Unit 2 is kept in operation during the remodeling work of each unit for Unit 1, targeting each unit. 1
After the remodeling work for each unit of Unit No. 1 is completed, the hall call button for Unit No. 1 will be repaired from a relay type to a microcomputer type, but since the hall call button at this time is connected to a common circuit, it is under construction During period x, Units 1 and 2 must be stopped at the same time. Next, when the remodeling work of the hall call button is completed, the remodeling work of the No. 2 machine is performed while the No. 1 machine is operated by using the renovated hall call button. When Unit 2 is connected to the previous landing call button after the modification work of Unit 2 is completed, as the landing call button is connected to the common circuit as described above, Units 1 and 2 are stopped simultaneously for the period y. I have to let you.

[Problems to be Solved by the Invention] Since the conventional method for modifying an elevator combined is as described above, it is necessary to stop both units at the same time twice when modifying the hall call button. However, if the hall call button is selected to be modified on Saturday and Sunday so as not to affect the user, the construction period will be extended.

An object of the present invention is to provide a modified construction method for an attached elevator that can reduce the chance of stopping two attached elevators at the same time.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention has a microcomputer-type landing call button connected to a control device for microcomputer control when the modification work of the elevator that has been started first is completed. Was temporarily installed near the relay-type landing call button, and when the elevator remodeling work for the person who started later was completed, the above-mentioned microcomputer-type landing-call button was replaced in place of the relay-type landing call button. Characterize.

[Operation] Since the method for modifying the elevator together with the elevator according to the present invention is performed as described above, the work of temporarily installing the microcomputer hall call button near the relay hall call button can be performed without stopping the operation of the other elevator. Since both elevators can be stopped once compared with the conventional method, the construction period can be shortened.

Embodiments Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a process diagram of the modified construction method. During the construction of the first unit, which started the remodeling work earlier, the second unit is in operation and continues to provide services to users. When the modification work of the No. 1 machine is completed, as shown in FIG. 3, for the No. 1 machine, the microcomputer type landing call button 4 connected to the microcomputer type control device (not shown) via the cable 5 and the relay type landing call button 3 are connected. Temporarily installed near the. During this side-by-side work, the No. 2 unit 2 continues service by using the relay-type landing call button 3.

Next, we will start the modification of Unit 2, but during this modification work,
The No. 1 machine 1 can continue the service to the user by using the microcomputer type landing call button 4. Therefore, until now, either one of the elevators is in operation.

When the remodeling work of the No. 2 machine, which was started to be remodeled later, is completed, the connection work with the microcomputer type landing call button is performed as shown in FIG. This connection work is divided into a connection work a on the car side of the second car and a connection work b with a common circuit connected to the microcomputer type control device. The wiring work a can be performed while the first machine is in operation, but since the common circuit section is involved in the wiring work b, it is necessary to stop the operation of the first machine as well. During this work time z, the operation of both machines is stopped. .

By these operations, the relay-type landing call button 3 shown in FIG. 3 is removed, and instead, the microcomputer-type landing call button 4 is permanently installed.
By operating the microcomputer type landing call button 4, the No. 1 and No. 2 units are controlled and the remodeling work is completed.

Therefore, in the conventional method shown in FIG. 2, it was necessary to stop both machines at the same time twice, but in this method, both machines are stopped once. Moreover, if it is set to stop both units at the same time on a holiday so as to minimize the impact on users, the conventional method requires a construction period that includes two weeks of holidays, whereas this method requires one week. Only the construction period including holidays is required, and the construction period will be short.

[Effects of the Invention] As described above, according to the present invention, the microcomputer type hall call button connected to the microcomputer type control device is temporarily installed near the relay type hall call button, and then the second elevator is modified. As a result, it is possible to reduce the chances of stopping both elevators at the same time and to provide a modified construction method for the side-by-side elevator that has less impact on the user.

Claims (1)

[Claims] 1. The one elevator separated from the relay hall call button is being modified, the other elevator to be modified later is in operation, and the one elevator is operated while the other elevator is being modified. In the annex elevator remodeling method, temporarily install a microcomputer-type hall call button connected to the microcomputer-type control device near the relay-type hall call button after the one elevator has been remodeled, and then use the microcomputer-type hall call. The other elevator is remodeled while the one elevator is operating with the button, and after this remodeling, the microcomputer type hall call button is permanently installed in place of the relay type hall call button.
