  The landing door 26 is provided on the building wall surface of the landing 13 on each floor, and a landing operation panel 26 b having a call button 26 a for the car 14 is installed at a position adjacent to the landing door 26. The landing doors 26 installed on each floor are configured to open and close in conjunction with the operation of the opening and closing door 16 only when the car 14 is stopped at an opposing position.

  The elevator control unit 34 is installed in the machine room M, and is electrically connected to each component of the elevator 10 such as the hoisting machine 12, the car 14, the operation panel 18, and the scale unit 24 described above. Measurement data is constantly obtained from each of these components.

  Further, the elevator control unit 34 includes a door-opening travel protection unit 34a composed of a UCMP (Unified Car Movement Protection) circuit and a backup power source 34b. This door-opening travel protection unit 34a detects the car 14 by the braking force of the brake unit 12a when it detects that the car 14 is moving up and down with either the door 16 or the landing door 26 open. It is a safety device that stops lifting. The backup power source 34b is an emergency power source for raising and lowering the car 14 to the nearest floor 13 in the event of an earthquake or power failure. The communication unit AP is an access point installed in the machine room M, is electrically connected to the elevator control unit 34, and has a role of connecting a maintenance terminal described later to the elevator control unit 34 by wireless communication. Yes.

  The elevator inspection device 40 includes a maintenance terminal 42 that is connected to an elevator control unit 34 that comprehensively controls the operation of the elevator 10 via a communication unit AP. The maintenance terminal 42 can be a laptop computer that can be carried and operated by maintenance personnel. Various maintenance programs are installed in the maintenance terminal 42 and can be connected to the communication unit AP of the elevator 10 by wireless communication. The maintenance terminal 42 may be connected to the elevator control unit 34 by wired communication.

  The maintenance terminal 42 has a function of executing an inspection operation such as a periodic inspection for the elevator 10. Below, the inspection method of the elevator 10 by the maintenance terminal 42 is demonstrated.

  FIG. 2 shows a maintenance / inspection screen 44 displayed on the screen screen 42 a of the maintenance terminal 42 when the maintenance terminal 42 is connected to the elevator control unit 34.

  The maintenance check screen 44 is provided with various automatic check display fields (1) on the left side and a manual check display field (2) composed of inspection items that require some manual operations on the right side. In the various automatic check display fields (1), the lifting / lowering speed, brake static torque, brake dynamic torque, scale no-load measurement, scale operation measurement, UCMP specific distance sensing device confirmation, earthquake control operation, fire control operation, blackout light The items of the operation test and the direct speech test are displayed in order from the top. In order to select the ascending / descending speed among these inspection items, a check mark 48a displayed on the left end portion of the maintenance inspection screen 44 may be clicked to display a “re” mark. Similarly, other check items can be selected by clicking the check boxes 50a, 52a, 54a, 56a, 58a, 60a, 62a, 64a, 66a displayed on the left side. It is also possible to collectively select the above-described inspection items by clicking the all selection button 70a displayed below each inspection item. Then, by selecting the execution button 70b displayed in the lower part of the center of the maintenance inspection screen 44, the elevator 10 is changed from the normal operation to the inspection mode via the elevator control unit 34, and each of the above selected items is selected. Inspection operations corresponding to the inspection items are continuously executed in order from the top. Hereinafter, each inspection operation will be described in order.

  The check of the ascending / descending speed is performed by raising or lowering the car 14 between the uppermost floor and the lowermost floor in a no-load state, and whether the maximum speed when rising and falling is within 125% of the specified speed, for example. It is to confirm. When the raising / lowering operation of the car 14 is completed, the maximum speed at the time of ascent and descent is displayed in the inspection result columns 48b and 49b, respectively, and the maintenance terminal 42 determines that these maximum speeds satisfy the acceptance criteria. Is displayed in the column 48c, 49c of “OK” and “NG” in the case of failure. Accordingly, the inspection evaluation can be displayed together with the inspection result, so that the inspection work can be performed efficiently. In the case of failure, the background color of the inspection evaluation fields 48c and 49c may be changed to red to make it easily noticeable, or an “x” mark may be displayed instead of “NG”. Good.

  Moreover, it is preferable that the maintenance terminal 42 performs voice guidance instructing to get off the car 14 via the interphone 18d before executing the inspection of the lifting speed. This makes it difficult for maintenance personnel to forget to get out of the car 14 and thus troubles such as redoing the inspection work, so that the inspection operation can be carried out more smoothly.

  In the following, the display contents of the inspection result and inspection evaluation column in each inspection operation are substantially the same as the inspection operation of the lifting speed described above, and thus the description thereof will be omitted as appropriate.

  The check of the brake static torque is performed when the rotational driving force is increased stepwise up to an output corresponding to 200% in normal operation in a state where the braking force is applied to the hoisting machine 12 by the braking unit 12a. 12 is an inspection operation in which the amount of slippage 12 is measured by a sensor (not shown). In this inspection operation, when the rotational force of less than 180% is applied, if the hoisting machine 12 does not slip, the maintenance terminal 42 determines that the acceptance criterion is satisfied.

  For checking the brake dynamic torque, for example, an inspection operation for measuring the braking distance when the braking unit 12a is operated while the car 14 is raised and the car 14 is suddenly stopped is repeatedly executed three times. If the average value is within the specified range, the maintenance terminal 42 determines that the acceptance criterion is satisfied.

  The scale no-load measurement test is a test for confirming whether or not the weighing unit 24 has properly detected the loaded weight, and is detected by the weighing unit 24 in a no-load state in which no person or luggage is loaded on the car 14. Check the load to be performed. In this inspection operation, the load detected by the scale unit 24 is displayed as a percentage in the inspection result column 54b as a percentage of the maximum load of the car 14, and the error included in the detected load is within 10%. It is judged by the maintenance terminal 42 that it satisfies the acceptance criteria.

  In the weighing operation measurement test, a signal when the weighing unit 24 detects overloading from the maintenance terminal 42 in a state where the car 14 is stopped at the landing 13 on the lowest floor, for example, is transmitted to the elevator controller 34 in a pseudo manner. Then, a warning sound for notifying overloading is sounded from the intercom 18d, and it is confirmed whether the door 16b of the car 14 is opened. In this scale operation measurement test, the elevator control unit 34 determines whether or not a signal for causing the above warning sound to the interphone 18d and a signal for opening the door 16 are properly transmitted. The maintenance terminal 42 determines whether or not the acceptance criteria are satisfied.

  The inspection of the UCMP specific distance sensing device is performed by using a landing plate 25a provided immediately below the landing door 26 of each floor when the landing sensor 25 of the passenger car 14 is moved up and down toward an arbitrary floor. This is a test to check whether it can be detected properly. The landing plate 25a is provided with, for example, five reference positions along the vertical direction. Each reference position has “0”, “6”, “2”, “1” from top to bottom. , “0” is set in order. The reference position of the identification number “2” indicates the landing floor level that is the position of the floor of each landing 13. Each reference position given another identification number is a position for detecting a door zone that can open and close the door 16 when the car 14 stops at the landing 13. In this inspection operation, the car 14 is moved up and down toward the landing 13 on an arbitrary floor, and the landing sensor 25 sets the reference position of the landing plate 25a in the order of “0”, “1”, and “2” when ascending. It detects whether the landing sensor 25 detects the reference position of the landing plate 25a in the order of “0”, “6”, “2” when descending. In the inspection result column 58b, the reference positions detected at the time of rising are displayed in order, and if the identification numbers are displayed in the order of “0” → “1” → “2”, the acceptance criteria are satisfied. In the inspection result column 59b, the reference positions detected at the time of lowering are displayed in order, and if the identification numbers are displayed in the order of “0” → “6” → “2”, the acceptance criteria are satisfied. In the present embodiment, an example is given in which the inspection of the UCMP specific distance sensing device is performed without maintenance personnel getting into the car 14, but the maintenance personnel may get into the car 14 and perform the inspection. In this case, it is possible to make an announcement to the maintenance staff that stops the car 14 at the preset floor 13 and opens the door 16 and prompts the car to enter the car 14 via the intercom 18d. preferable. Further, the order in which the reference position of the landing sensor 25 is detected may be displayed on the indicator 18c of the operation panel 18. Thereby, the maintenance staff can confirm the detection status visually.

  To check the control operation during an earthquake, a pseudo signal notifying the occurrence of an earthquake is transmitted from the maintenance terminal 42 to the elevator control unit 34, and the car 14 is placed on the nearest floor 13 by the backup power source 34 b built in the elevator control unit 34. This is a test for confirming whether or not an announcement that prompts the passenger to evacuate is made from the intercom 18d while stopping up and down until the door 16 is opened. In this inspection operation, the voltage of the backup power supply 34b is displayed in the inspection result column 60b, the voltage is equal to or higher than a predetermined reference value, and the seismic control operation is performed based on the signal received by the elevator control unit 34. When the maintenance terminal 42 determines that is executed as prescribed, it is determined that the acceptance criteria are satisfied.

  In the present embodiment, the maintenance terminal 42 can also execute a fire control operation, a power failure lamp operation test, and a direct speech test. The inspection of fire control operation is performed by transmitting a pseudo signal indicating the occurrence of a fire from the maintenance terminal 42 to the elevator control unit 34, and the car 14 is automatically raised and lowered to an evacuation floor set on the first floor, for example. It is a test which stops in the state which opened 16 and confirms whether the announcement which prompts a passenger to evacuate is appropriately performed via the intercom 18d. The blackout lamp operation test is a test for confirming that the blackout lamp 14a installed in the car 14 is turned on when a pseudo signal indicating the occurrence of a blackout is transmitted from the maintenance terminal 42 to the elevator controller 34. The direct speech test is a test for confirming whether or not a call can be made with an information center that remotely monitors the elevator 10. These fire control operation, blackout lamp operation test, and direct talk test are performed by the car 14 as prescribed based on various signals that the elevator control unit 34 transmits and receives to and from the car 14 and other components. The maintenance terminal 42 determines whether it is operating or not.
