An embodiment of an elevator apparatus 100 of the present invention will be described below with reference to FIGS. 1 to 4. FIG. In each figure, the same components are denoted by the same reference numerals, and repeated descriptions are omitted. In addition, in the following description, the vertical direction corresponds to the vertical direction of the car 104 .

A configuration of the elevator apparatus 100 will be described with reference to FIG. FIG. 1 is a schematic diagram showing a cross section of an elevator apparatus 100 according to an embodiment of the present invention as viewed from the side.

The elevator apparatus 100 includes a car 104 and a counterweight 105 that ascend and descend in a hoistway 101, a hoisting machine 103 around which a main rope (not shown) is wound, and a car 104 that stands vertically in the hoistway 101. car guide rails 106 and 107 for guiding the elevation of the elevator car; and a control device (elevator control device) 102 for controlling the up-and-down operation of the elevator device 100 .

A car 104 and a counterweight 105 are provided inside a hoistway 101 provided in a building, and are suspended by a main rope wound around a hoisting machine 103 in a looped manner.

Automatic adjustment of the car position during maintenance work of the elevator device 100 will be described with reference to FIGS. 1 and 2. FIG. FIG. 2 is a schematic diagram showing a state in which the car 104 is positioned and stopped during maintenance work of the control device 102 in the elevator device 102 according to one embodiment of the present invention.

In the elevator device 100, the hoisting machine 103 and the control device 102 are raised in consideration of flooding. That is, the hoisting machine 103 and the control device 102 are arranged on a specific floor which is raised to a position higher by the height He than the floor level 1FL of the first floor. Note that the first floor is the floor at approximately the same height as the ground, that is, the floor closest to the ground.

Here, the specific floor is the floor that is higher than the height position at which there is a possibility of being submerged (hereinafter referred to as the submerged height) and that is closest to the submerged height. In addition, the height of flooding shall be the height position of flooding specified in the hazard map. That is, the specific floor (installation floor) where the hoisting machine 103 and the control device 102 are installed is the floor that is higher than the flood height specified in the hazard map and closest to the flood height.

The raising height He in this case is set based on the case where the hoisting machine 103 and the control device 102 are arranged on the floor level 1FL of the first floor.

Since the hoisting machine 103 and the control device 102 are installed on a specific floor, the specific floor may be referred to as the installation floor of the hoisting machine 103 and the control device 102 or simply the installation floor.

In this embodiment, the flood height is higher than the floor level 1FL of the first floor and lower than the floor level 2FL of the second floor. In this case, the specific floor (installation floor) is the second floor, and the hoist 103 and the control device 102 are installed on the second floor.

1 and 2 merely show that the specific floor is the second floor with respect to the arrangement of the hoisting machine 103 and the control device 102. is not limited to the arrangement illustrated in FIG. In this embodiment, at least the control device 102 of the hoisting machine 103 and the control device 102 may be arranged on a specific floor, and the hoisting machine 103 and the control device 102 may be arranged on different floors. . However, in terms of maintenance of the elevator system 100, it is more convenient to arrange both the hoisting machine 103 and the control device 102 on the same floor. The control device 102 arranged on the specific floor will be described below.

During maintenance work such as an insulation test of the control device 102, the top of the car (upper surface) 104a of the car 104 is positioned at the floor level 2FL of the second floor, which is a specific floor, and a worker gets on the top 104a of the car 104. perform maintenance work. That is, in this embodiment, the top 104a of the car 104 serves as a foothold for the worker.

Therefore, in order to enable the worker to board from the landing floor to the upper car 104a, the car 104 is first positioned so that the upper car 104a coincides with the floor level 1FL of the boarding floor (for example, the first floor). do. In this case, the top of the car 104a does not need to match the floor level 1FL of the boarding floor, and may be positioned inside the range in which the worker can board (the boarding range in FIG. 2).

When the operator has finished getting on the top of the car 104a, the top of the car (upper surface) 104a of the car 104 is positioned at the floor level 2FL of the second floor, which is the specific floor.

FIG. 3 is a block diagram showing a schematic configuration of the control device 102 according to one embodiment of the invention.

When positioning the car top (upper surface) 104a of the car 104 at the floor level of a specific floor, the floor (specific floor) on which the control device 102 is installed is also different because the flood height specified in the hazard map differs for each elevator device. . Therefore, logic for identifying the installation floor of the control device 102 is required.

In the present embodiment, a floor that is higher than the flood height specified in the hazard map and that is closest to the flood height is specified as the installation floor (specific floor), and the car top (upper surface) 104a of the car 104 is the specific floor. floor level. The movement (lifting/lowering) of the car 104 for this purpose will be referred to as "specific floor movement operation". The flood height specified by the hazard map is called "flood height information 411". Further, in order to specify (calculate) a specific floor, the height (floor height data) Hfl (see FIG. 2) of each floor 1FL, 2FL, . I will call.

Since the car height Hc (see FIG. 2) of the car 104 differs depending on the specifications of the elevator device 100, in order to position the car top (upper surface) 104a of the car 104 at the floor level of the specific floor, the floor height information 412 It is necessary to perform a specific floor transfer operation according to the car height Hc. The car height used in this specific floor transfer operation is called "car height information 413".

During maintenance work, a handrail 104b is installed on the car 104a. The handrail 104b is stored in the upper car 104a in a folded state, and is unfolded to the upper car 104a during maintenance work. That is, the car 104 has a built-in handrail 104b on the top of the car 104a.

During maintenance work on the control device 102, it is necessary to open the lid of the control device 102, and the lid of the control device 102 and the handrail 104b may interfere with each other. For this reason, after the worker gets into the upper car 104a, it is necessary to move the car 104 to a height position (hereinafter referred to as "maintenance height") where the cover of the control device 102 and the handrail 104b do not interfere. That is, it is necessary to move the car 104 to a maintenance position where the lid of the controller 102 can be opened when the handrail 104b is assembled and the lid of the controller 102 can be placed on the handrail 104b.

In addition to the handrail 104b, equipment such as an air conditioner (hereinafter referred to as equipment installed on the car) is mounted on the top 104a of the car, which may become an obstacle during maintenance work of the control device 102. FIG. For this reason, positional adjustment (adjustment) in the height direction (vertical direction) for moving the car 104 to a position where maintenance can be easily performed is performed according to the height of the handrail Hhr (see FIG. 2) and the height of the equipment installed on the car. driving). Therefore, in this embodiment, the position of the car 104 is adjusted using the height information of the handrail 104b and the equipment installed on the car. The height information of obstacles such as the handrail 104b and equipment installed on the car will be referred to as "obstacle information 414". In FIG. 2, as a representative of the obstacle information 414, only the handrail height Hhr is shown. The handrail height Hhr dimension may be identified from the product specification car height Hc and the handrail type. In this case, the obstacle information 414 is the product specification car height Hc and handrail type.

In this embodiment, the position adjustment in the height direction is automatically performed. Hereinafter, this position adjustment will be referred to as maintenance height automatic adjustment operation. In the description below, the position adjustment of the car 104 is the position adjustment in the height direction (vertical direction).

It is assumed that the control device 102 is installed such that the height position of its lowest end matches the floor level of the specific floor. In this case, the installation height of the control device 102 matches the floor level of the specific floor. However, the control device 102 is not limited to this, and the control device 102 may be arranged at a position raised by a predetermined height dimension from the floor level of the specific floor. In this case, the installation height of the control device 102 with respect to the floor level of the specific floor is the height position obtained by adding the raised predetermined height dimension to the floor level of the specific floor. It is preferable to adjust the minute in the maintenance height automatic adjustment operation. The installation height of the control device 102 with respect to the floor level is called "base height information 415".

Note that when the height position of the lowest end of the control device 102 matches the floor level of the specific floor, the base height information 415 becomes zero (0). Also, when the base height information 415 is unified to zero (0), the base height information 415 becomes unnecessary.

The control device 102 has different height dimensions depending on its type and capacity. Therefore, in the maintenance height automatic adjustment operation, it is preferable to adjust the position of the car 104 in consideration of this height dimension. Information such as the type, capacity and height of the control device 102 will be referred to as "model information 416".

Depending on the content of the maintenance work, the location or parts of the control device 102 to be inspected differ. Therefore, in the maintenance height automatic adjustment operation, it is preferable to adjust the position of the car 104 in consideration of the location or parts to be inspected. Since the magnitude of this position adjustment is determined according to the contents of the maintenance work, the information used for this position adjustment will be referred to as "work content information 431".

The flood height information 411 is information determined by the flood height designated by the hazard map as described above, and is stored in the storage unit 402 of the control device 102 . Floor height information 412 , car height information 413 , obstacle height information 414 , base height information 415 , and model information 416 are information determined by customer specifications and stored in storage unit 402 . The work content information 431 is information different for each maintenance work, and is input from the input device 403 of the control device 102 for each maintenance work. The control device 102 inputs submerged height information 411, floor height information 412, car height information 413, obstacle height information 414, base height information 415, model information 416, and work content information 431, and displays the 4 includes a microcomputer 401 that executes various processes described in 4. Based on the processing result of the microcomputer 401 , the control device 102 automatically executes a specific floor movement operation and an automatic maintenance height adjustment operation, controls the hoist 103 , and positions the car 104 .

FIG. 4 is a flow chart of the positioning operation of the car to the installation floor of the control device according to one embodiment of the present invention.

In step S1, the car 104 is positioned so that the top of the car 104a coincides with the floor level 1FL of the boarding floor (for example, the first floor), and the worker boards the top of the car 104a from the landing floor.

In step S2, the normal operation mode is shifted to the maintenance mode (maintenance mode) using the on-car maintenance signal or the handrail signal (HRS) as a trigger. The on-car maintenance signal is a signal issued by operating a switch for switching to the maintenance mode, and this switch is provided on the on-car 104a. A handrail signal is a signal emitted by deploying a folded handrail. In addition to these signals, a signal emitted when a landing side door (hatch door) is opened, or customer specification information may be used as a trigger signal.

After shifting to the maintenance mode, in step S3, the submerged height information 411 and the floor height information 412 are compared to identify the installation floor (specific floor) of the control device 102 .

In step S4, the floor height of the specific floor is specified as the installation position of the control device 102 (A). That is, in this embodiment, it is assumed that the height position of the lowest end of the control device 102 matches the floor level of the specific floor, and the floor level of the specific floor is specified as the installation position (height position) of the control device 102. be done.

In step S5, the car height Hc and the handrail type of the product specification are used as the obstacle information 414, and the height dimension of the handrail is specified from the car height Hc and the handrail type (B).

In step S6, a specific maintenance signal and an operation (UP/DN) signal are input to the controller 102. FIG. The specific maintenance signal is a signal that designates the content of maintenance. The height to be adjusted in the position adjustment of the car 104 (maintenance height automatic adjustment operation) is changed according to the content of this maintenance work. The operation (UP/DN) signal corresponds to a start switch signal, the completion of the input work is transmitted to the control device 102, and the operation mode in the maintenance mode (maintenance operation mode) is started. The maintenance operation mode is a mode for actually raising and lowering the car 104, and includes an input mode for inputting and setting information and a maintenance operation mode.

In step S7, the positional relationship between (A) and (B) is calculated. (A) is the floor level of the specific floor specified as the installation position of the control device 102, and (B) is the height dimension of the handrail specified as the obstacle. By calculating the positional relationship between (A) and (B), the height position of the car top 104a of the car 104 including the position adjustment is specified. In identifying the height position including this position adjustment, the maintenance target component and its height position are identified based on the specific maintenance signal (maintenance work content) input in step S6.

In step S8, it is determined whether or not the height of the part to be maintained and the handrail are the same. If the maintenance target part (maintenance target position) of the control device 102 and the handrail are at the same height, the handrail 104b interferes with access to the maintenance target component (maintenance target position) during maintenance, so the process proceeds to step S9. . If the maintenance target part (maintenance target position) of the control device 102 and the handrail are not at the same height, the handrail 104b does not interfere with access to the maintenance target component (maintenance target position) during maintenance. move on.

In step S9, the position of the upper car 104a is automatically adjusted to a position that does not interfere with maintenance work, and the process proceeds to step S11. In this case, the position of the upper car 104a is automatically adjusted from the position specified in (A) to a position that does not interfere with maintenance work.

In step S10, the position of the upper car 104a is automatically adjusted to the position specified in (A), and the process proceeds to step S11. In this case, the car 104 is positioned on the assumption that no positional adjustment with respect to the obstacle is necessary.

In step S11, the worker performs maintenance work.
