Description

Method for renovating elevator

Technical Field

The invention relates to a method for renovating an elevator.

Background

In an existing elevator, in order to cope with aged deterioration of equipment or to achieve improvement in performance such as energy saving, the elevator is refurbished. In this case, during a renovating operation of an elevator in which at least some of the devices of an existing elevator are renovated, it is necessary to continuously stop the operation of the elevator for a long time. Therefore, long-term suspension of the elevator becomes a large obstacle to the modernization.

Therefore, a method of retrofitting an elevator to shorten an elevator continuous suspension period in an elevator retrofitting work period has been proposed (for example, see patent document 1). In the refresh method described in patent document 1, specifically, in the initial stage of refresh, an existing control panel (hereinafter, referred to as an old control panel) is replaced with a new control panel (hereinafter, referred to as a new control panel).

In addition, "communication" used in the embodiments includes transmission and reception of various signals such as a control signal, a voltage signal, and a current signal.

Embodiment mode 1

Fig. 1 is a configuration diagram showing an elevator apparatus to which a method for modernizing an elevator according to embodiment 1 of the present invention is applied. As shown in fig. 1, a hoisting machine 2 including a hoisting motor, a control panel 3 for controlling an elevator, and a speed governor 4 are provided in a machine room 1. The hoistway 5 is provided with a car 6, a counterweight 7, a main rope 8 connecting the car 6 and the counterweight 7, a guide rail 9, and a terminal switch 10.

The car 6 is provided with a door drive device 11. The door driving device 11 includes: a door motor that drives a car door provided in the car 6; an encoder which detects a rotational position of the door motor; and a full-close detector that detects that the car door is fully closed. In the car 6, a car operating panel 12 is provided. A landing operating panel 14 is provided at the landing 13. A buffer 16 is provided in the pit 15.

The car controller 18 is provided on the car 6, and more specifically, for example, on the car 6. The car controller 18 is connected to the control panel 3 via a movement cable 17. The car controller 18 is connected to the door driving device 11, the car operating panel 12, a ceiling device (not shown) provided on the ceiling of the car 6, a floor-stopping detection device (not shown) that detects that the car 6 stops at the landing 13, and the like by cables (not shown). The ceiling device is, for example, a lighting device provided on the ceiling of the car 6. The car controller 18 controls the connected devices in accordance with the instructions received from the control panel 3. Specifically, for example, the car controller 18 controls the door driving device 11 to open and close the car door in accordance with an instruction received from the control panel 3.

Here, the equipment related to the car 6 is referred to as car equipment. Specific examples of such car equipment include a car controller 18, a door driving device 11, a car operating panel 12, a moving cable 17, ceiling equipment, a floor stop detection device, and the like. Further, the equipment related to the landing 13 is referred to as landing equipment. Specific examples of such a landing device include the landing operating panel 14. Further, the equipment related to the hoistway 5 is referred to as hoistway equipment. Specific examples of such a hoistway device include a terminal switch 10, a hoistway cable (not shown), and the like. Hereinafter, the landing equipment and the hoistway equipment are referred to as landing/hoistway equipment.

Next, the division work procedure performed during the renovation work of the elevator will be described with reference to fig. 2. Fig. 2 is a table showing an example of a series of division construction steps of an elevator refurbishing method according to embodiment 1 of the present invention.

Here, in order to shorten the elevator continuous suspension period in the elevator refurbishment period, the refurbishment is divided into a plurality of division steps. Each of the divided construction steps is completed within a continuous and ensured time, and after each of the divided construction steps is completed, the user can use the elevator. That is, in order to shorten the elevator continuous suspension period in the refresh operation period of the elevator, it is a precondition that the elevator can be used at the time when each division work step ends. For example, in an apartment, it is necessary to be able to use an elevator in the morning and evening hours when a large number of users are going to work, commute, etc., and in a restaurant rental building, it is necessary to be able to use an elevator in the business hours such as the evening and night.

Therefore, when retrofitting at least a part of the equipment of the elevator, the contents of the retrofitting are divided into a series of division work steps in units of the elevator being in a state in which normal operation is possible after each division work step is completed. And performing a refurbishment project according to the series of segmentation construction steps. As shown in fig. 2, the contents of the refurbishment process are divided into three division steps, i.e., a division step S1 to a division step S3. However, depending on the specifications of the elevator, each division work step may be further divided.

In the division construction step S1, a new control panel is provided separately from the existing control panel. Next, an existing old hoisting machine as an example of the 1 st old equipment is refurbished. The main devices to be refurbished in the division construction step S1 are a control panel, a hoisting machine, a main rope, a weighing device, and the like. After the division construction step S1 is completed, the elevator is in a state in which normal operation is possible.

In the division construction step S2, an existing old car device, which is an example of the 2 nd old device, is retrofitted. The division construction step S2 is performed after the division construction step S1. The main devices to be refurbished in the division construction step S2 are a car controller, a door driving device, a car operating panel, a moving cable, a ceiling device, a floor stop detection device, and the like. After the division construction step S2 is completed, the elevator is in a state in which normal operation is possible.

In the division construction step S3, an existing old landing/hoistway device, which is an example of the 3 rd old device, is retrofitted. The division construction step S3 is performed after the division construction step S2. The main devices to be retrofitted in the division construction step S3 are a landing operating panel, an end switch, a hoistway cable, and the like. After the division construction step S3 is completed, the elevator is in a state in which normal operation is possible.

In this way, when one of the series of divided construction steps is completed, the elevator is in a state in which normal operation is possible. Therefore, when one divided construction step is finished, a time period in which the user can use the elevator is formed, and the elevator continuous suspension period can be shortened.

(renewing method)

Next, a method of retrofitting an elevator according to embodiment 1 will be described with reference to fig. 3 to 7. Fig. 3 is a block diagram showing an initial state of an elevator apparatus to which the method for modernizing an elevator according to embodiment 1 of the present invention is applied.

As shown in fig. 3, the existing old control panel 100 includes an old control board 110 as a control board for controlling the elevator apparatus. In the initial state of the elevator apparatus, the old control board 110 of the old control panel 100 is connected to the existing old hoisting machine 200, the existing old car device 300, and the existing old landing/hoistway device 400, respectively.

The communication method applied to the old control board 110 is, for example, a serial communication method. Hereinafter, the communication method applied to the old control board 110 is referred to as an "old communication method". The old control board 110 controls the elevator apparatus by communicating with the old hoisting machine 200, the old car device 300, and the old landing/hoistway device 400 by the old communication method.

(division construction step S1: control panel setting/traction machine renovation)

Next, the division construction step S1 will be described with reference to fig. 4. Fig. 4 is a block diagram showing a state of the elevator apparatus after the division construction step S1 is performed on the initial state of the elevator apparatus of fig. 3.

In the division construction step S1, a step of installing the new control panel 100A at a position different from the old control panel 100 in the machine room is performed. The new control panel 100A includes a new control board 110A as a control board for controlling the elevator apparatus. By performing this step, the old control panel 100 and the new control panel 100A coexist.

Next, a process of replacing the old control board 110 of the old control board 100 with the communication conversion board 120 is performed. In this step, specifically, the old control board 110 is detached from the old control board 100, and the communication switching board 120 is attached to the old control board 100. By performing this step, the old control panel 100 includes the communication conversion board 120. The size of the old control substrate 110 is, for example, the same as that of the communication converting substrate 120.

Next, a step of connecting the new control board 110A of the new control panel 100A and the communication switching board 120 of the old control panel 100 is performed. Next, a step of connecting the communication conversion board 120 of the old control panel 100 to each of the old car device 300 and the old landing/hoistway device 400 is performed.

Next, a step of replacing the old hoisting machine 200 with the new hoisting machine 200A is performed. In this step, specifically, the old hoisting machine 200 is replaced with the new hoisting machine 200A. Next, a step of connecting the new control board 110A of the new control panel 100A and the new hoisting machine 200A is performed.

The communication method applied to the new control board 110A is, for example, a serial communication method such as a CAN (Controller Area Network) communication method. Hereinafter, the communication method applied to the new control board 110A is referred to as a "new communication method". The new communication system can transmit and receive data of a larger capacity than the old communication system and has a data transmission speed higher than that of the old communication system. The new control board 110A controls the elevator apparatus by communicating with the new hoisting machine 200A, the new car device 300A described below, and the new landing/hoistway device 400A described below, respectively, by a new communication method.

Next, the structure of the communication conversion board 120 will be described with reference to fig. 5. Fig. 5 is a block diagram illustrating the structure of the communication conversion substrate 120 of fig. 4. The communication conversion board 120 is configured to convert the communication method between the old communication method and the new communication method. Specifically, as shown in fig. 5, the communication conversion board 120 includes a CPU (Central Processing Unit) 121 and a RAM (Random Access Memory) 122.

The CPU121 converts the data format from the old car device 300 into data corresponding to the new control board 110A, and stores the data in the RAM 122. The format refers to a data structure such as a bit number. The CPU121 converts the data format from the new control board 110A into data corresponding to the old car device 300, and stores the data in the RAM 122.

The CPU121 takes out and outputs the format-converted data from the RAM122 in response to a request from the new control board 110A. The CPU121 takes out the format-converted data from the RAM122 and outputs the data in response to a request from the old car device 300. Thus, even if the communication method to be applied is different, the new control board 110A of the new control board 100A can communicate with the old car device 300 via the communication conversion board 120.

Similarly, the CPU121 converts the data format from the old landing/hoistway equipment 400 into data corresponding to the new control board 110A, and stores the data in the RAM 122. The CPU121 converts the data format from the new control board 110A into data corresponding to the old landing/hoistway equipment 400, and stores the data in the RAM 122.

The CPU121 takes out and outputs the format-converted data from the RAM122 in response to a request from the new control board 110A. The CPU121 takes out the format-converted data from the RAM122 and outputs the data in response to a request from the old landing/hoistway equipment 400. Thus, even if the communication method to be applied is different, the new control board 110A of the new control panel 100A can communicate with the old landing/hoistway equipment 400 via the communication changeover board 120.

As a specific example, consider the case where the old car device 300 includes an existing old car operating panel. In this case, the new control board 110A communicates with the old car operating panel via the communication conversion board 120. For example, the new control board 110A provides a display command for causing the display of the old car operating panel to display information to the old car operating panel by such communication. As another example, the new control board 110A receives operation information indicating that a button, a switch, or the like of the old car operation panel is pressed from the old car operation panel by such communication.

As a specific communication method of the old communication method and the new communication method, the following example can be considered. That is, as example 1, a case where both the old communication method and the new communication method are the serial communication method can be considered. As example 2, a case where both the old communication method and the new communication method are the parallel communication method may be considered. As example 3, a case where the old communication method is the serial communication method and the new communication method is the parallel communication method may be considered. As an example 4, a case where the old communication method is the parallel communication method and the new communication method is the serial communication method may be considered.

Thus, the 1 st division construction step S1, which is one of the series of division construction steps, includes at least the following 4 steps a1 to a 4.

(step A1) A step of providing a new control panel 100A having a new control board 110A to which a new communication method is applied, separately from the old control panel 100 having the old control board 110 to which the old communication method is applied

(step a2) a step of replacing the old hoisting machine 200 as an example of the 1 st old equipment with a new hoisting machine 200A as an example of the 1 st new equipment and connecting the new hoisting machine 200A and the new control board 110A of the new control panel 100A

(step A3) of replacing the old control board 110 of the old control board 100 with the communication switching board 120 for switching the communication method between the old communication method and the new communication method

(step a4) of connecting the communication switching board 120 of the old control panel 100 to each of the old car device 300 as an example of the old 2 nd device and the old landing/hoistway device 400 as an example of the old 3 rd device

When the above-described steps are performed, the new control board 110A of the new control panel 100A can communicate with the new hoisting machine 200A, and can communicate with the old car device 300 and the old landing/hoistway device 400 having different communication methods, respectively, via the communication conversion board 120.

Therefore, after the division construction step S1 is completed, the new control panel 100A can be brought into a state in which the elevator can be controlled by the new control panel 100A in a state in which the old control panel 100 and the new control panel 100A coexist, and as a result, the elevator can be brought into a state in which normal operation is possible.

(division construction step S2: car equipment refurbishment)

Next, the division construction step S2 will be described with reference to fig. 6. Fig. 6 is a block diagram showing the state of the elevator apparatus after the division construction step S2 has been performed on the state of the elevator apparatus of fig. 4.

In the division construction step S2, a process of renewing the old car facility 300 to the new car facility 300A is performed. In this step, specifically, the old car device 300 is replaced with the new car device 300A. Next, a step of connecting the new control board 110A of the new control panel 100A and the new car device 300A is performed.

In this way, the 2 nd division construction step S2, which is one of the series of division construction steps, includes at least the following step B1.

(step B1) a step of replacing the old car device 300, which is an example of the 2 nd old device, with a new car device 300A, which is an example of the 2 nd new device, and connecting the new car device 300A to the new control board 110A of the new control panel 100A

When the above-described steps are performed, the new control board 110A of the new control panel 100A can directly communicate with each of the new hoisting machine 200A and the new car device 300A, and can communicate with the old landing/hoistway device 400 having a different communication method via the communication conversion board 120 of the old control panel 100.

Therefore, after the division construction step S2 is completed, the new control panel 100A can be brought into a state in which the elevator can be controlled by the new control panel 100A in a state in which the old control panel 100 and the new control panel 100A coexist, and as a result, the elevator can be brought into a state in which normal operation is possible.

(division construction step S3: renovation of landing/hoistway Equipment)

Next, the division construction step S3 will be described with reference to fig. 7. Fig. 7 is a block diagram showing the state of the elevator apparatus after the division construction step S3 has been performed on the state of the elevator apparatus of fig. 6.

In the division construction step S3, a step of renewing the old landing/hoistway equipment 400 into a new landing/hoistway equipment 400A is performed. In this step, specifically, the old landing/hoistway equipment 400 is replaced with the new landing/hoistway equipment 400A. Next, a step of connecting the new control board 110A of the new control panel 100A and the new landing/hoistway device 400A is performed.

In this way, the 3 rd division construction step S3, which is one of the series of division construction steps, includes at least the following step C1.

(step C1) a step of retrofitting the old landing/hoistway device 400, which is an example of the 3 rd old device, to a new landing/hoistway device 400A, which is an example of the 3 rd new device, and connecting the new landing/hoistway device 400A to the new control board 110A of the new control panel 100A.

When the above-described steps are performed, the new control board 110A of the new control panel 100A can directly communicate with each of the new hoisting machine 200A, the new car device 300A, and the new landing/hoistway device 400A.

Therefore, after the division construction step S3 is completed, the new control panel 100A can be brought into a state in which the elevator can be controlled by the new control panel 100A in a state in which the old control panel 100 and the new control panel 100A coexist, and as a result, the elevator can be brought into a state in which normal operation is possible.

If the above series of division construction steps of the division construction step S1 through the division construction step S3 are all completed, the renovation of the elevator is completed. As described above, when the refurbishment of the elevator is completed, all the devices to be refurbished are connected to the new control panel 100A, and therefore the old control panel 100 is not necessary. The old control panel 100 that is not needed can be removed. The timing to remove the old control panel 100 may be, for example, when the refresh operation is completed or when the elevator is maintained. Further, the communication conversion board 120 of the old control board 100 can be reused.

In addition, the dividing step S2 and the dividing step S3 may be performed in any order. In addition, all the steps of the division construction step S2 and the division construction step S3 are not necessarily required to be performed, and some of the steps may be omitted.

Further, the hoisting machine is listed as an example of the type of the 1 st old equipment, the car equipment is listed as an example of the type of the 2 nd old equipment, and the landing/hoistway equipment is listed as an example of the type of the 3 rd old equipment, but the present invention is not limited thereto. That is, the 1 st old device may be one selected from three types of a hoisting machine, a car device, and a landing/hoistway device, the 2 nd old device may be one selected from the remaining two types, and the 3 rd old device may be one selected from the remaining one.

As described above, according to embodiment 1, in the method for renewing an elevator, the 1 st division construction step includes the steps of: setting a new control panel separately from the old control panel; renovating the 1 st old equipment into the 1 st new equipment, and connecting the 1 st new equipment with the new control substrate of the new control panel; replacing an old control substrate of an old control panel with a communication conversion substrate; and connecting the communication conversion substrate of the old control panel with the 2 nd old equipment and the 3 rd old equipment respectively. After the 1 st division construction step is completed, the new control board of the new control panel communicates with the 1 st new device and communicates with the 2 nd old device and the 3 rd old device via the communication changeover board, respectively, so that the new control board can control the elevator.

This can shorten the elevator continuous suspension period in the elevator refurbishment process period. Further, even if the old control panel 100 is not removed, the new control panel 100A can be set independently of the old control panel 100, and therefore, the time required for completing the setting of the new control panel 100A can be shortened. Further, since the old hoisting machine 200 can be replaced with the new hoisting machine 200A after the new control panel 100A is installed, the operation performance of the elevator can be improved at an early stage.

In the refresh method described in patent document 1, cables of the old car equipment and the old landing equipment need to be connected to a new control panel. However, when a cable is connected to a new control panel, the type of connector of the cable and the pin number of the connector do not match, and therefore a dedicated wire harness must be prepared. In contrast, in the retrofitting method according to embodiment 1, it is not necessary to connect cables of the old car equipment 300 and the old landing/hoistway equipment 400 to the new control panel 100A. Therefore, it is not necessary to prepare a dedicated wire harness.

The division construction step S2 of embodiment 2 is further divided into a division construction step S2-1 and a division construction step S2-2. In embodiment 2, two types of old car devices 300, i.e., an old car operating panel and an old car door driving device, are exemplified.

In the division construction step S2-1, a step of retrofitting the old car door drive device, which is an example of the old car equipment 300 of the type α, to a new car door drive device is performed. In this step, specifically, a step of retrofitting the old car door drive apparatus to a new car door drive apparatus is performed. Next, a step of connecting the new control board 110A of the new control panel 100A to the new car door driving apparatus is performed.

In this way, the divisional construction step S2-1, which is a further divisional construction step S2 that is one of the series of divisional construction steps, includes at least the following steps B1 and B2.

(step B1) the step of replacing the old car facility 300 of the type α with the new car facility 300A of the type α (step B2) connects the new control board 110A of the new control panel 100A with the new car facility 300A of the type α

When the above-described steps are performed, the new control board 110A of the new control panel 100A can communicate with the old car devices 300 of the type β having a different communication method and the old hall/hoistway devices 400 having a different communication method, respectively, via the communication changeover board 120 of the old control panel 100. The new control board 110A can communicate with the new hoisting machine 200A and the new car device 300A of the type α, respectively.

Therefore, after the division construction step S2-1 is completed, the new control panel 100A can be in a state in which the elevator can be controlled by the new control panel 100A in a state in which the old control panel 100 and the new control panel 100A coexist, and as a result, the elevator can be in a state in which normal operation is possible.

In the division construction step S2-2 after the division construction step S2-1 is performed, a process of renewing the old car operating panel, which is an example of the old car device 300 of the type β, to a new car operating panel is performed. In this step, specifically, a step of renewing the old car operating panel with the new car operating panel is performed. Next, a step of connecting the new control board 110A of the new control panel 100A and the new car operating panel is performed.

In this way, the divisional construction step S2-2, which is a further divisional construction step S2 that is one of the series of divisional construction steps, includes at least the following steps B3 and B4.

(step B3) the step of renewing the old car facility 300 of the type β to the new car facility 300A of the type β (step B4) is a step of connecting the new control board 110A of the new control panel 100A and the new car facility 300A of the type β

When the above-described steps are performed, the new control board 110A of the new control panel 100A can communicate with the old landing/hoistway equipment 400 having a different communication method via the communication changeover board 120 of the old control panel 100. The new control board 110A can communicate with the new hoisting machine 200A, the new car device 300A of the type α, and the new car device 300A of the type β, respectively.

Therefore, after the division construction step S2-2 is completed, the new control panel 100A can be in a state in which the elevator can be controlled by the new control panel 100A in a state in which the old control panel 100 and the new control panel 100A coexist, and as a result, the elevator can be in a state in which normal operation is possible.

As can be seen from the above, in embodiment 2, the new control board 110A may be in a state in which the elevator can be controlled during the execution of the dividing construction step S2. Specifically, it is assumed that the new control board 110A can control the elevator in a situation where a new car device 300A of a certain type shown in fig. 9 coexists with an old car device 300 of another type. This enables the elevator to be in a normal operation state at the stage in which the dividing construction step S2 is performed.

(division construction step S3: renovation of landing/hoistway Equipment)

Fig. 11 is a block diagram showing the state of the elevator apparatus after the division construction step S3 has been performed on the state of the elevator apparatus of fig. 10. The dividing construction step S3 of embodiment 3 is the same as the dividing construction step S3 of embodiment 1, and therefore, the description thereof is omitted.

As described above, according to embodiment 2, the new control board 110A of the new control panel 100A is in a state in which the elevator can be controlled during the execution of the dividing construction step S2, as compared with the method for retrofitting an elevator according to embodiment 1. Thus, when the types of the old car devices 300 are large and the old car devices 300 of all types cannot be refurbished at one time, the old car devices 300 of all types can be refurbished a plurality of times.

Embodiment 3

In embodiment 3 of the present invention, a method of retrofitting an elevator, which is different from the above-described embodiments 1 and 2, will be described. Note that, in embodiment 3, the description of the same points as those in embodiments 1 and 2 described above is omitted, and the description is mainly focused on the differences from embodiments 1 and 2 described above.

First, the division procedure performed during the renovation work of the elevator according to embodiment 3 will be described with reference to fig. 12.

(division construction step S4: traction machine renovation)

Next, the division construction step S4 will be described with reference to fig. 16. Fig. 16 is a block diagram showing the state of the elevator apparatus after the division construction step S4 has been performed on the state of the elevator apparatus of fig. 15.

In the dividing construction step S4, a step of renewing the old hoisting machine 200 with the new hoisting machine 200A is performed. In this step, specifically, the old hoisting machine 200 is replaced with the new hoisting machine 200A. Next, a step of connecting the control unit 111A of the new control board 110A and the new hoisting machine 200A is performed.

Further, a step of disconnecting the communication converting portion 112A of the new control board 110A from the new car device 300A and connecting the control portion 111A of the new control board 110A to the new car device 300A is performed. Further, a step of disconnecting the communication switching part 112A of the new control board 110A from the new landing/hoistway equipment 400A and connecting the control part 111A of the new control board 110A to the new landing/hoistway equipment 400A is performed.

When the above steps are performed, the control unit 111A of the new control board 110A can communicate with the new hoisting machine 200A, the new car device 300A, and the new landing/hoistway device 400A, respectively.

Therefore, after the division construction step S4 is completed, the new control panel 100A can be brought into a state in which the elevator can be controlled by the new control panel 100A in a state in which the old control panel 100 and the new control panel 100A coexist, and as a result, the elevator can be brought into a state in which normal operation is possible.

If the above series of division construction steps of the division construction step S1 through the division construction step S4 are all completed, the renovation of the elevator is completed. In addition, all of the steps from the division construction step S2 to the division construction step S4 are not necessarily required to be performed, and some of the steps may be omitted.

Further, a car device is exemplified as an example of the type of the 1 st old device, a landing/hoistway device is exemplified as an example of the type of the 2 nd old device, and a hoisting machine is exemplified as an example of the type of the 3 rd old device, but the present invention is not limited thereto. That is, the 1 st old device may be one selected from three types of a hoisting machine, a car device, and a landing/hoistway device, the 2 nd old device may be one selected from the remaining two types, and the 3 rd old device may be one selected from the remaining one.

After the 1 st division construction step is completed, the old control board 110 of the old control panel 100 is in a state in which the elevator can be controlled.

This can shorten the elevator continuous suspension period in the refresh operation period of the elevator. Further, even if the old control panel 100 is not removed, the new control panel 100A can be set independently of the old control panel 100, and therefore, the time required for completing the setting of the new control panel 100A can be shortened. Further, compared to embodiment 1, it is not necessary to prepare the communication conversion substrate 120.

In the above-described embodiment, the present invention is applied to the case where the old car device 300, the old landing/hoistway device 400, and the old hoisting machine 200 are retrofitted to the new car device 300A, the new landing/hoistway device 400A, and the new hoisting machine 200A, respectively, but the present invention is not limited to this.
