For this purpose, a tension wheel 28c suspended from the governor rope 28a and a grip portion 28d for gripping the governor rope 28a may be provided.

The car 22 may include, for example, a stop portion 22a that stops the car 22 by sandwiching the car rails 26, and a transmission portion 22b that transmits the operation of the speed governor 28 to the stop portion 22a. Then, for example, when the speed of the car 22 exceeds the set speed, the gripping portion 28d grips the governor rope 28a, and the travel of the governor rope 28a is stopped, whereby the stopping portion 22a of the car 22 is operated. may be configured.

In addition, the elevator 21 preferably includes the load detection unit 30 that detects the load inside the car 22, for example, as in the present embodiment. The configuration of the load detection unit 30 is not particularly limited. It may be a connected sensor (for example, a load cell).

As shown in FIG. 2, the rope tester device 2 includes, for example, a rope tester 3 that contacts the car rope 23 to inspect the car rope 23, a moving unit 4 that moves the rope tester 3, and each part of the rope tester device 2. may be provided with a tester processing unit 5 for controlling the Although the rope tester device 2 inspects the cage rope 23 in this embodiment, it may inspect the governor rope 28a, for example.

The moving unit 4 may include, for example, a contact/separation moving unit 6 capable of moving the rope tester 3 in a direction in which the rope tester 3 approaches or separates from the car rope 23 . The contact/separation moving unit 6 includes, for example, a first moving unit 6a that moves the rope tester 3 in a first direction D1, and a second moving unit that moves the rope tester 3 in a second direction D2 orthogonal to the first direction D1. 6b.

The rope tester 3 may have, for example, a groove 3a extending along the third direction D3 at its tip. Then, when the rope tester 3 inspects the cage rope 23, the cage rope 23 may be inserted into the groove 3a, and the groove 3a may be in contact with the cage rope 23. The third direction D3 is a direction orthogonal to the first direction D1 and the second direction D2.

Although not shown, the rope tester 3 may include, for example, a permanent magnet and a magnetic flux detector (eg, detection coil, Hall element) inside. As a result, for example, the permanent magnet magnetizes the car ropes 23, and the magnetic flux detector detects magnetic flux (for example, magnetic flux leaking from the car ropes 23 and magnetic flux passing through the inside of the car ropes 23). Damage (eg, broken wires) can be inspected.

As shown in FIG. 3, the rope tester device 2 may include, for example, an input section 7 for inputting information and an inspection output section 8 for outputting inspection results.

The running of the car 22 may be controlled by controlling the hoist 25 based on .

It is preferable that the second calculation unit 29c includes an inspection availability determination unit 29e that determines whether the car rope 23 can be inspected based on the detection by the load detection unit 30, for example, as in the present embodiment. For example, when it is determined that there is no person inside the car 22 based on the detection by the load detection unit 30, the inspection propriety determining unit 29e determines that the car rope 23 can be inspected (inspectable). In this case, when it is determined that there is a person inside the car 22, it may be determined that the car rope 23 cannot be inspected (inspection not possible).

Note that the tester processing unit 5 and the elevator processing unit 29 control the elevator system 1 respectively. That is, the elevator system 1 has a processing device 1 a composed of a tester processing section 5 and an elevator processing section 29 . The tester processing section 5 and the elevator processing section 29 are preferably capable of communicating with each other, for example, when they are separate devices as in the present embodiment.

As a result, the tester processing unit 5 controls the contact/separation moving unit 6 to move the rope tester 3, and when the rope tester 3 inspects the car rope 23, that is, while the rope tester device 2 is inspecting the rope, the elevator By controlling the hoisting machine 25, the processing unit 29 can run the specified car 22 for rope inspection. Note that the tester processing section 5 and the elevator processing section 29 may be configured as an integrated device, that is, a single device.

Also, although not particularly limited, the prescribed running of the cage 22 for rope inspection may be, for example, running in one direction at a constant speed while the rope tester 3 is in contact with the cage rope 23 . Further, for example, the running speed (maximum speed) of the car 22 during rope inspection may be slower than the running speed (maximum speed) of the car 22 during normal operation.

Each processing unit 5, 29 includes processors such as CPU and MPU (for example, each calculation unit 5c, 29c, each control unit 5d, 29d), memories such as ROM and RAM (for example, each acquisition unit 5a, 29a, each storage 5b, 29b), various interfaces (for example, acquisition units 5a, 29a), and the like. The units 5a to 5d and 29a to 29d of the processing units 5 and 29 may be realized by the processor executing the programs stored in the memory and the software and hardware cooperating.

For example, a configuration may be adopted in which each of the units 5a to 5d and 29a to 29d of each of the processing units 5 and 29 is implemented by a processor in one computer executing processing. Specifically, the units 5a to 5d and 29a to 29d of the processing units 5 and 29 may be provided in one device, for example.

Further, for example, the configuration may be such that the respective units 5a to 5d and 29a to 29d of the respective processing units 5 and 29 are realized by processors in a plurality of computers performing processing in a distributed manner. Specifically, the units 5a to 5d and 29a to 29d of the processing units 5 and 29 may be distributed among a plurality of devices capable of communicating with each other.

The configuration of the elevator system 1 according to this embodiment is as described above. Next, control of the elevator system 1 according to this embodiment will be described. In addition, the control of the elevator system 1 is not limited to the following contents.

First, when a person is inside the car 22 , it is necessary to let the person out of the car 22 from inside the car 22 . Therefore, for example, before the start of the rope inspection (for example, 3 to 5 minutes before the start of the inspection), the second control unit 29d controls the car output unit 22c so that the car output unit 22c It is preferable to output the information that the examination is started.

For example, the start of the inspection and the unusable elevator 21 may be displayed on the car output unit 22c, which is a display, or announced by the car output unit 22c, which is a speaker. Further, for example, by turning off the car output unit 22c, which is the lighting inside the car 22, the start of the inspection and the fact that the elevator 21 cannot be used may be output.

As a result, when a person is inside the car 22 before the rope inspection starts, the person inside the car 22 can be made to recognize that the rope inspection will start and that the elevator 21 will become unusable. . Therefore, for example, a person inside the car 22 can be encouraged to leave the car 22 .

Further, for example, before the start of the rope inspection (for example, immediately before the start of the inspection to 1 minute before the start of the inspection), the inspection propriety determination unit 29e determines whether the car rope 23 can be inspected based on the detection by the load detection unit 30. is preferred. As a result, when there is no person inside the car 22, the inspection propriety determining unit 29e determines that the inspection is possible.

For example, when the inspection propriety determination unit 29e determines that the inspection is not possible, the cage output unit 22c may output information that the inspection of the cage rope 23 is started. That is, when it is a set period (for example, immediately before the start of the inspection to 5 minutes before the start of the inspection) before the start of the rope inspection and the inspection propriety determination unit 29e determines that the inspection is not possible, the car output unit 22c starts the rope inspection. A configuration of outputting information may also be used.

Then, when the inspection propriety determination unit 29e determines that the inspection is possible, the inspection of the car rope 23 is started. Specifically, the first control unit 5d controls the moving unit 4 to move the rope tester 3 so as to contact the car rope 23, and the second control unit 29d controls the hoist 25, The car 22 makes a prescribed run for rope inspection. Thereby, the inspection of the car rope 23 can be automatically performed.

By the way, during the rope inspection, the information input to the hall operating panel 32 is invalidated. Thus, the running of the car 22 is not controlled based on the information input to the hall control panel 32 during the rope inspection. Therefore, even if information is input to the hall operating panel 32 during the rope inspection, the specified car 22 for rope inspection can be run, and for example, the car rope 23 can be properly inspected. .

In addition, the configuration in which the information input to the hall operating panel 32 is invalidated is not particularly limited. For example, the hall operating panel 32 may be configured not to output information (output signal) to the processing device 1a. may be disabled.

On the other hand, the information input to the car operating panel 31 is valid even during the rope inspection. When information is input to the car operating panel 31 during the rope inspection, the second control unit 29d controls the running of the car 22 so that the car 22 stops at the landing. This can prevent people from being trapped inside the car 22, for example, during rope inspection.

The landing where the car 22 stops may be, for example, the nearest landing when the information is input to the car operating panel 31, or may be, for example, a predetermined landing (for example, an evacuation floor landing, etc.). . For example, when information is input to the destination input section of the car operation panel 31, the landing where the car 22 stops is the input landing, and when information is input to other input sections, the closest landing is selected. A floor or a predetermined boarding hall may be used.

Note that the inspection propriety determination unit 29e may determine whether or not the car rope 23 can be inspected based on the detection by the load detection unit 30 not only before the rope inspection is started but also during the rope inspection. During the rope inspection, if the inspection propriety determination unit 29e determines that the inspection is not possible, the same control as when information is input to the car operating panel 31 may be performed.

By stopping the car 22 at the landing in this manner, the car 22 does not run as specified for rope inspection, so the inspection of the car rope 23 is stopped. At this time, when the car 22 is running, the position of the rope tester 3 is held, and after the car 22 stops running, the first control unit 5d controls the moving unit 4 to The tester 3 leaves the cage rope 32. As a result, when the rope tester 3 separates from the car rope 23 , it is possible to prevent the rope tester 3 from wearing or damaging the car rope 23 , for example.

Then, after the car 22 has stopped at the landing, the rope inspection may be resumed when the inspection availability determining unit 29e determines that the inspection is possible. Alternatively, the rope inspection may not be restarted unless a manual recovery operation is performed after the car 22 has stopped at the landing. Then, when the rope inspection is completed or when the rope inspection is not restarted, the processing device 1a causes the car 22 to run in normal operation.

As described above, as in the present embodiment, the elevator system 1 includes a car 22 that travels in the vertical direction, a rope (a car rope in this embodiment) 23 that travels with the travel of the car 22, and the car. 22, a hall operating panel 32 arranged at the landing, and based on the information input to the car operating panel 31 and the hall operating panel 32, the car 22 is operated. A processing device 1a to control, a rope tester 3 in contact with the rope 23 to inspect the rope 23, and a moving unit 4 for moving the rope tester 3 with respect to the rope 23, the processing device 1a controls the moving unit 4 so that the rope tester 3 is in contact with the rope 23 during inspection of the rope 23, and the processing device 1a controls the hall operating panel 32 during inspection of the rope 23. A preferred configuration is to invalidate the information entered in the .

According to such a configuration, since the information input to the hall operation panel 32 is invalidated during the inspection of the rope 23, the running of the car 22 is controlled based on the information input to the hall operation panel 32. not. As a result, even when information is input to the hall operating panel 32, the specified car 22 can run during the rope 23 inspection.

Further, as in the present embodiment, in the elevator system 1, the processing device 1a validates the information input to the car operation panel 31 during the inspection of the rope 23, and the processing device 1a enables the It is preferable to control the running of the car 22 so that the car 22 stops at the landing when information is input to the car operation panel 31 during the inspection of the rope 23 .

According to such a configuration, the information input to the car operating panel 31 is valid even during the inspection of the rope 23. Therefore, when the information is input to the car operating panel 31, the processing device 1a can cause the car 22 to travel. , the car 22 stops at the landing. As a result, for example, it is possible to prevent a person from being confined inside the car 22 while the rope 23 is being inspected.

Further, as in the present embodiment, in the elevator system 1, the processing device 1a controls the moving section 4 so that the rope tester 3 separates from the rope 23 after the car 22 stops running. It is preferable to configure

According to such a configuration, after information is input to the car operation panel 31 and the car 22 stops running, the processing device 1a controls the moving section 4 . Thereby, the rope tester 3 can be separated from the rope 23 after the rope 23 stops running.

Further, as in the present embodiment, the elevator system 1 further includes a load detection section 30 that detects the load inside the car 22, and the processing device 1a detects the load based on the load detection section 30. A configuration in which an inspection propriety determination unit 29 e that determines whether or not the rope 23 can be inspected is preferably provided.

According to such a configuration, the load detection unit 30 detects the load inside the car 22 , and the inspection availability determination unit 29 e determines whether the rope 23 can be inspected based on the detection by the load detection unit 30 . Thereby, the rope 23 can be inspected when there is no person inside the car 22 .

Further, as in the present embodiment, in the elevator system 1, the car 22 has a car output section 22c that outputs information toward the inside, and the processing device 1a starts inspecting the rope 23. It is preferable that the car output unit 22c is caused to output the information that the inspection of the rope 23 is started in advance.

According to such a configuration, before the inspection of the rope 23 is started, the car output section 22c outputs the information that the inspection of the rope 23 is started. Thereby, when a person is inside the car 22 before the inspection of the rope 23 is started, the person inside the car 22 can be made to recognize that the inspection of the rope 23 is started.

It should be noted that the elevator system 1 is not limited to the configuration of the embodiment described above, nor is it limited to the effects described above. Further, the elevator system 1 can of course be modified in various ways without departing from the gist of the present invention.
