DETAILED DESCRIPTION

[0021] Below, use Figures 1 to 4 The embodiment of the elevator device 100 of the present invention will be described. In each figure, the same structure is marked with the same reference numerals, and repeated descriptions are omitted. In the following description, the up and down direction is consistent with the ascending and descending direction of the car 104.

[0022] refer to Figure 1 The structure of the elevator apparatus 100 will be described. Figure 1 This 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.

[0023] The elevator device 100 includes: a car 104 and a counterweight 105 that are raised and lowered in a lifting passage 101; a traction machine 103 around which a main hoisting rope (not shown) is wound; car guide rails 106 and 107 that are vertically arranged in the lifting passage 101 in the up-down direction and guide the lifting of the car 104; counterweight guide rails 108 and 109 that are vertically arranged in the lifting passage 101 in the up-down direction and guide the lifting of the counterweight 105; and a control device (elevator control device) 102 that controls the lifting and lowering operation of the elevator device 100, including the lifting and lowering of the car 104.

[0024] The car 104 and the counterweight 105 are installed inside a hoistway 101 provided in a building, and are suspended in a bucket-like manner by a main rope wound around the hoisting machine 103 .

[0025] use Figure 1 as well as Figure 2 Automatic adjustment of the car position during maintenance work of the elevator apparatus 100 will be described. Figure 2 This is a schematic diagram showing a state in which the car 104 is positioned and stopped during maintenance work of the control device 102 of the elevator device 102 according to an embodiment of the present invention.

[0026] In the elevator device 100, the hoisting machine 103 and the control device 102 are elevated in consideration of flooding. That is, the hoisting machine 103 and the control device 102 are arranged on a specific floor elevated to a position higher by a height He than the floor level 1FL of the first floor. The first floor is a floor located at approximately the same height as the ground, that is, a floor closest to the ground.

[0027] Here, the specific layer is a layer higher than the height position where flooding is possible (hereinafter referred to as the flooding height) and closest to the flooding height. In addition, the flooding height is set to the height position of the flooding specified in the disaster map. That is, the specific layer (installation layer) where the traction machine 103 and the control device 102 are installed is a layer higher than the flooding height specified in the disaster map and closest to the flooding height.

[0028] The lifting 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 surface 1FL of the first floor.

[0029] Since the hoisting machine 103 and the control device 102 are installed in a specific layer, the specific layer may be referred to as an installation layer of the hoisting machine 103 and the control device 102 or simply referred to as an installation layer for explanation.

[0030] In this embodiment, the flood height is set higher than the floor level 1FL of the 1st floor and lower than the floor level 2FL of the 2nd floor. In this case, the specific floor (installation floor) is the 2nd floor, and the hoisting machine 103 and the control device 102 are installed on the 2nd floor.

[0031] in addition, Figure 1 as well as Figure 2 The arrangement of the hoisting machine 103 and the control device 102 is merely shown as the second specific floor, but the arrangement of the hoisting machine 103 and the control device 102 in the specific floor is not limited to the second specific floor. Figure 1 In the present embodiment, at least the control device 102 of the traction machine 103 and the control device 102 may be arranged on a specific floor, and the traction machine 103 and the control device 102 may be arranged on different floors. However, in terms of maintenance of the elevator device 100, it is more convenient to arrange both the traction machine 103 and the control device 102 on the same floor. The following describes the control device 102 arranged on a specific floor.

[0032] During maintenance work such as insulation testing of the control device 102, the car upper surface (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 climbs onto the car upper surface 104a of the car 104 to perform maintenance work. That is, in this embodiment, the car upper surface 104a of the car 104 serves as a foothold for the worker.

[0033] Therefore, in order for the operator to climb onto the car upper surface 104a from the lobby floor, the car 104 is first positioned so that the car upper surface 104a coincides with the floor level 1FL of the landing layer (e.g., the first floor). In this case, the car upper surface 104a does not need to coincide with the floor level 1FL of the landing layer, but is positioned within the range where the operator can climb ( Figure 2 Just put it on the inside of the climbing range.

[0034] When the operator completes climbing onto the car upper surface 104a, the car upper surface (upper surface) 104a of the car 104 is positioned at the floor level 2FL of the second floor, which is the specific floor.

[0035] Figure 3 It is a block diagram showing a schematic configuration of a control device 102 according to an embodiment of the present invention.

[0036] When the car upper surface (upper surface) 104a of the car 104 is positioned at the floor level of a specific layer, since the flood height specified in the disaster map is different for each elevator device, the installation layer (specific layer) of the control device 102 is also different. Therefore, logic for determining the installation layer of the control device 102 is required.

[0037] In this embodiment, a layer that is higher than the flood height specified in the disaster map and closest to the flood height is determined as the installation layer (specific layer), and the car upper surface (upper surface) 104a of the car 104 is positioned at the floor level of the specific layer. The movement (lifting and lowering) of the car 104 used for this is called "specific layer movement operation". In addition, the flood height specified in the disaster map is called "flood height information 411". In addition, in order to determine (calculate) the specific layer, the height (floor height data) Hfl of each layer 1FL, 2FL, ... is required (reference Figure 2 ), and the floor height data is referred to as "floor height information 412".

[0038] Since the car height Hc of the car 104 (refer to Figure 2 ) varies according to the specifications of the elevator device 100. Therefore, in order to position the car upper surface (upper surface) 104a of the car 104 at the floor level of a specific floor, it is necessary to perform a specific floor moving operation corresponding to the floor height information 412 and the car height Hc. The car height used in the specific floor moving operation is called "car height information 413".

[0039] Furthermore, during maintenance work, a handrail 104b is provided on the car upper surface 104a. The handrail 104b is stored in a folded state on the car upper surface 104a, and is unfolded on the car upper surface 104a during maintenance work. That is, the car 104 is provided with an assembled handrail 104b on the car upper surface 104a.

[0040] During maintenance work on the control device 102, the cover of the control device 102 needs to be opened, and there is a possibility that the cover of the control device 102 and the handrail 104b may interfere with each other. Therefore, after the operator climbs onto the upper surface 104a of the car, the car 104 needs to be moved to a height position (hereinafter referred to as the maintenance height) where the cover of the control device 102 and the handrail 104b do not interfere with each other. That is, when assembling the handrail 104b, the cover of the control device 102 needs to be opened, and the car 104 needs to be moved to the maintenance position where the cover of the control device 102 is placed on the handrail 104b.

[0041] In addition to the handrail 104b, the car upper surface 104a is also equipped with equipment such as an air conditioner (hereinafter referred to as the car upper surface installation equipment), which may become an obstacle during the maintenance work of the control device 102. Therefore, it is necessary to adjust the handrail height Hhr (refer to Figure 2 ) and the height of the equipment installed on the car surface to adjust the position of the car 104 in the height direction (up and down direction) to a position where maintenance can be easily performed (adjustment operation). Therefore, in this embodiment, the height information of the handrail 104b, the equipment installed on the car surface, etc. is used to adjust the position of the car 104. The height information of obstacles such as the handrail 104b and the equipment installed on the car surface is called "obstacle information 414". Figure 2 , only the handrail height Hhr is recorded as a representative of the obstacle information 414. The handrail height Hhr size may also be determined based on the car height Hc and the handrail type of the product specification, and the obstacle information 414 in this case becomes the car height Hc and the handrail type of the product specification.

[0042] In this embodiment, the position adjustment in the height direction is automatically performed. Hereinafter, this position adjustment is referred to as maintenance height automatic adjustment operation. In the following description, the position adjustment of the car 104 is the position adjustment in the height direction (up and down direction).

[0043] In addition, the control device 102 is set so that the height position of its lowest end is consistent with the floor level of the specific layer. In this case, the setting height of the control device 102 is consistent with the floor level of the specific layer. However, this is not limited to this, and the control device 102 can also be configured at a position where a given height dimension is further raised from the floor level of the specific layer. In this case, the setting height of the control device 102 relative to the floor level of the specific layer becomes a height position obtained by adding the given height dimension raised to the floor level of the specific layer, and the given height dimension raised can be adjusted during the automatic maintenance height adjustment operation. The setting height of the control device 102 relative to the floor level is referred to as "base height information 415".

[0044] When the height position of the lowest end of the control device 102 coincides with the floor level of the specific floor, the base height information 415 becomes zero (0). When the base height information 415 is unified to zero (0), the base height information 415 is unnecessary.

[0045] The height of the control device 102 varies depending on its type and capacity. Therefore, in the automatic maintenance height adjustment operation, it is preferable to adjust the position of the car 104 in consideration of the height. Information such as the type, capacity, and height of the control device 102 is referred to as "machine model information 416".

[0046] Depending on the content of the maintenance work, the place or parts inspected by the control device 102 are different. Therefore, in the maintenance height automatic adjustment operation, it is preferable to adjust the position of the car 104 in consideration of the place or parts to be inspected. Since the size of the position adjustment is determined according to the content of the maintenance work, the information used in the position adjustment is called "work content information 431".

[0047] The flood height information 411 is information determined based on the flood height specified in the disaster map as described above, and is stored in the storage unit 402 of the control device 102. The floor height information 412, the car height information 413, the obstacle height information 414, the foundation height information 415, and the machine model information 416 are information determined based on customer specifications, and are stored in the storage unit 402. The operation content information 431 is information that is different for each maintenance operation, and is input from the input device 403 of the control device 102 for each maintenance operation. The control device 102 includes: a microcomputer 401, which receives the flood height information 411, the floor height information 412, the car height information 413, the obstacle height information 414, the foundation height information 415, the machine model information 416, and the operation content information 431, and executes Figure 4 The control device 102 automatically executes a specific floor moving operation and a maintenance height automatic adjustment operation based on the processing result of the microcomputer 401 , and controls the hoisting machine 103 to position the car 104 .

[0048] Figure 4 This is a flow chart of the positioning operation of a car to a floor where a control device is installed according to one embodiment of the present invention.

[0049] In step S1, the car 104 is positioned so that the car upper surface 104a is aligned with the floor level 1FL of the landing floor (for example, the first floor), and the operator climbs onto the car upper surface 104a from the hall floor.

[0050] In step S2, the car upper surface maintenance signal (car upper maintenance signal) or handrail signal (HRS) is used as a trigger to shift from the normal operation mode to the maintenance mode (maintenance mode). The car upper surface maintenance signal is a signal issued by operating a switch for switching to the maintenance mode, and the switch is provided on the car upper surface 104a. The handrail signal is a signal issued by unfolding a folded handrail. In addition to these signals, a signal issued when the hall side door (cabin door) is opened and customer specification information can also be used as a trigger signal.

[0051] When the mode is shifted to the maintenance mode, in step S3 , the flood height information 411 and the floor height information 412 are compared to determine the installation floor (specific floor) of the control device 102 .

[0052] In step S4, the floor height of the specific floor is determined as the installation position (A) of the control device 102. That is, in this embodiment, the floor level of the specific floor is determined as the installation position (height position) of the control device 102 on the premise that the height position of the lowest end of the control device 102 is consistent with the floor level of the specific floor.

[0053] In step S5, the car height Hc and the handrail type of the product specifications are used as the obstacle information 414, and the handrail height dimension (B) is determined based on the car height Hc and the handrail type.

[0054] In step S6, a specific maintenance signal and an operation (UP / DN) signal are input to the control device 102. The specific maintenance signal is a signal that specifies the maintenance content, for example, the maintenance work content such as insulation test and component replacement is input as the work content information 431. Corresponding to the maintenance work content, the height adjusted in the position adjustment (maintenance height automatic adjustment operation) of the car 104 is changed. The operation (UP / DN) signal is equivalent to a start switch signal, which transmits the completion of the input operation to the control device 102 and starts the operation mode in the maintenance mode (maintenance operation mode). The maintenance operation mode is a mode for actually performing the lifting and lowering operation of the car 104. The maintenance mode includes an input mode for inputting and setting information, and a maintenance operation mode.

[0055] In step S7, the positional relationship between (A) and (B) is calculated. (A) is the floor level of a specific layer determined as the installation position of the control device 102, and (B) is the height dimension of the handrail determined as an obstacle. By calculating the positional relationship between (A) and (B), the height position of the car upper surface 104a of the car 104 including the position adjustment amount is determined. In determining the height position including the position adjustment amount, the maintenance object part and its height position are determined based on the specific maintenance signal (maintenance work content) input in step S6.

[0056] In step S8, it is determined whether the maintenance target part and the handrail are at the same height. If the maintenance target part (maintenance target position) of the control device 102 and the handrail are at the same height, the handrail 104b becomes an obstacle to access to the maintenance target part (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 become an obstacle to access to the maintenance target part (maintenance target position) during maintenance, so the process proceeds to step S10.

[0057] In step S9, the position of the car upper surface 104a is automatically adjusted to a position that does not hinder maintenance work, and the process proceeds to step S11. In this case, the position of the car upper surface 104a is automatically adjusted from the position determined in (A) to a position that does not hinder maintenance work.

[0058] In step S10, the position of the car upper surface 104a is automatically adjusted to the position determined in (A), and the process proceeds to step S11. In this case, the car 104 is positioned without requiring position adjustment relative to an obstacle.

[0059] In step S11, the operator performs maintenance work.

[0060] In this embodiment, the car upper surface 104a of the car can be automatically positioned at the control device 102 which is arranged at a different height position for each elevator device 100 in order to avoid flooding, and when there is an obstacle such as a handrail 104b, the car upper surface 104a can be automatically positioned at a height position avoiding the obstacle. For example, when performing an insulation test of the control device 102, the car upper surface 104a which becomes a workbench can be moved to a height position such that the control panel insulation test part avoids the handrail 104b. That is, in this embodiment, an elevator device is provided, which can position and stop the car 104 so that the car upper surface 104a is consistent with the floor level of the control device 102 installation layer even if the installation layer of the control device 102 is different for each elevator device.
