Detailed Description
Hereinafter, an embodiment of an elevator apparatus 100 according to the present invention will be described with reference to fig. 1 to 4. In the drawings, the same components are denoted by the same reference numerals, and repetitive description thereof will be omitted. In the following description, the up-down direction coincides with the up-down direction of the car 104.
The structure of the elevator apparatus 100 will be described with reference to fig. 1. Fig. 1 is a schematic diagram showing a cross section of an elevator apparatus 100 according to an embodiment of the present invention, as seen from a side surface side.
The elevator apparatus 100 includes a car 104 and a counterweight 105 that are lifted up and down in a hoistway 101, a hoisting machine 103 around which a main rope, not shown, is wound, car guide rails 106 and 107 that are vertically installed in the hoistway 101 and guide the lifting of the car 104, counterweight guide rails 108 and 109 that are vertically installed in the hoistway 101 and guide the lifting of the counterweight 105, and a control device (elevator control device) 102 that controls the lifting operation of the elevator apparatus 100 including the lifting of the car 104.
The car 104 and the counterweight 105 are installed in a hoistway 101 provided in a building, and are suspended in a bucket by a main rope wound around a hoisting machine 103.
The automatic adjustment of the car position during maintenance work of the elevator apparatus 100 will be described with reference to fig. 1 and 2. Fig. 2 is a schematic diagram showing an elevator apparatus 102 according to an embodiment of the present invention, in a state in which a car 104 is positioned and stopped at the time of maintenance work of the control apparatus 102.
In the elevator apparatus 100, the hoisting machine 103 and the control device 102 are lifted up in consideration of flooding. That is, the hoisting machine 103 and the control device 102 are disposed at a specific floor raised to a position higher than the floor level 1FL of the floor 1 by the height He. The 1 layer is a layer located at approximately the same height as the ground, that is, the layer closest to the ground.
Here, the specific layer is a layer that is higher than a height position (hereinafter referred to as a flooding height) where flooding is likely and closest to the flooding height. Further, the flooding height is set as a flooding height position specified in the disaster map. That is, the specific floor (installation floor) where the hoisting machine 103 and the control device 102 are installed is a floor that is higher than the flooding height specified in the disaster map and closest to the flooding height.
The elevation height He in this case is set based on the floor level 1FL in which the hoisting machine 103 and the control device 102 are disposed at the floor level 1f of the floor level 1.
Since the hoisting machine 103 and the control device 102 are provided at a specific level, the specific level may be referred to as a set level of the hoisting machine 103 and the control device 102 or may be referred to as a set level only.
In the present embodiment, the flooding height is set to a height higher than the floor level 1FL of the 1 layer and lower than the floor level 2FL of the 2 layers. In this case, the specific floor (installation floor) is 2 floors, and the hoisting machine 103 and the control device 102 are installed in 2 floors.
In fig. 1 and 2, the specific layer is only shown as 2 layers for the arrangement of the hoisting machine 103 and the control device 102, and the arrangement of the hoisting machine 103 and the control device 102 in the specific layer is not limited to the arrangement shown in fig. 1. In the present embodiment, at least the control device 102 among the hoisting machine 103 and the control device 102 may be disposed on a specific floor, and the hoisting machine 103 and the control device 102 may be disposed on different floors. However, in terms of maintenance of the elevator apparatus 100, it is convenient to dispose both the hoisting machine 103 and the control device 102 on the same floor. The control device 102 disposed in a specific layer is described below.
In maintenance work such as insulation test of the control device 102, the upper car surface (upper surface) 104a of the car 104 is positioned at the floor level 2FL of the floor of the 2 floors as the specific floor, the worker performs maintenance work by boarding the upper surface 104a of the car 104. That is, in the present embodiment, the car upper surface 104a of the car 104 becomes a foothold for the worker.
Thus, in order for an operator to be able to board 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 boarding floor (e.g., floor 1). In this case, the car upper surface 104a does not need to be aligned with the floor level 1FL of the upper floor, and may be positioned inside the range (the boarding range in fig. 2) in which the worker can board.
When the worker completes boarding 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 floor 2 layer that is the specific layer.
Fig. 3 is a block diagram showing a schematic configuration of the control device 102 according to an embodiment of the present invention.
When the car upper surface (upper surface) 104a of the car 104 is positioned at the floor level of a specific floor, the floor (specific floor) to which the control device 102 is installed differs because the flooding height specified in the disaster map differs for each elevator device. Therefore, logic for determining the setting layer of the control device 102 is required.
In the present embodiment, a floor that is higher than the flooding height specified in the disaster map and closest to the flooding height is determined as a set floor (specific floor), and the car upper surface (upper surface) 104a of the car 104 is positioned at the floor level of the specific floor. The movement (lifting) of the car 104 used for this is referred to as "specific floor movement operation". Further, the flooding height specified in the disaster map is referred to as "flooding height information 411". In addition, in order to determine (calculate) a specific layer, the height (layer height data) Hfl (refer to fig. 2) of each layer 1FL, 2FL, and..is required, and this layer height data is referred to as "layer height information 412".
Since the car height Hc (see fig. 2) of the car 104 differs according to the specifications of the elevator apparatus 100, 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 in accordance with the floor height information 412 and the car height Hc. The car height used for the specific floor movement operation is referred to as "car height information 413".
In addition, during maintenance work, a handrail 104b is provided on the car upper surface 104 a. 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 includes assembled armrests 104b on the car upper surface 104 a.
In the maintenance work of 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 armrest 104b interfere with each other. Therefore, after the worker steps on the upper surface 104a of the car, the worker needs to move the car 104 to a height position (hereinafter referred to as a maintenance height) where the cover of the control device 102 and the handrail 104b do not interfere with each other. That is, it is necessary to open the cover of the control device 102 at the time of assembling the handrail 104b and move the car 104 to a maintenance position where the cover of the control device 102 is placed on the handrail 104 b.
An apparatus such as an air conditioner (hereinafter referred to as a car upper surface installation apparatus) is mounted on the car upper surface 104a in addition to the handrail 104b, and may become an obstacle in maintenance work of the control device 102. Therefore, it is necessary to adjust the position of the car 104 in the height direction (vertical direction) in which the car is moved to a position where maintenance can be easily performed in accordance with the height Hhr (see fig. 2) of the armrest and the height of the car upper surface installation equipment (adjustment operation). Therefore, in the present embodiment, the position of the car 104 is adjusted using the height information of the handrail 104b, the car upper surface installation equipment, and the like. The height information of the handrail 104b and the obstacle such as the car upper surface installation equipment is referred to as "obstacle information 414". In fig. 2, only the armrest height Hhr is described as a representative of the obstacle information 414. The handrail height Hhr may be determined based on the car height Hc and the handrail type of the product specification, and the obstacle information 414 in this case may be the car height Hc and the handrail type of the product specification.
In the present embodiment, the position adjustment in the height direction is automatically performed. Hereinafter, this position adjustment will be referred to as a 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-down direction).
In addition, the control device 102 is arranged such that the height position of the lowermost end thereof coincides with the floor level of a specific floor. In this case, the setting height of the control device 102 coincides with the floor level of the specific floor. However, the present invention is not limited to this, and the control device 102 may be disposed at a position further raised by a predetermined height from the floor level of a specific floor. In this case, the set height of the control device 102 with respect to the floor level of the specific floor becomes a height position where a given height dimension of elevation is added to the floor level of the specific floor, and the given height dimension of elevation can be adjusted in the maintenance height automatic adjustment operation. The set height of the control device 102 with respect to the floor level is referred to as "base (base) height information 415".
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). In addition, in the case where the base height information 415 is unified to zero (0), the base height information 415 is not required.
The height of the control device 102 varies depending on the type, capacity, and the like. Therefore, in the maintenance height automatic adjustment operation, the position of the car 104 is preferably adjusted in consideration of the height. Information such as the type, capacity, and height of the control device 102 is referred to as "model information 416".
The place or the component to be inspected by the control device 102 is different depending on the maintenance work. Therefore, in the maintenance height automatic adjustment operation, the position of the car 104 is preferably adjusted in consideration of the place or the component to be inspected. Since the size of the position adjustment is determined in accordance with the content of the maintenance work, information used for the position adjustment is referred to as "work content information 431".
As described above, the flooding height information 411 is determined based on the flooding height specified in the disaster map, 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 base height information 415, and the model information 416 are information determined according to the customer specifications, and are stored in the storage unit 402. The work content information 431 is information different for each maintenance work, and is input for each maintenance work from the input device 403 of the control device 102. The control device 102 includes a microcomputer 401 to which flooding height information 411, floor height information 412, car height information 413, obstacle height information 414, base height information 415, model information 416, and job content information 431 are input, and executes various processes described with reference to fig. 4. The control device 102 automatically executes the specific floor moving operation and the 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.
Fig. 4 is a flowchart of a positioning operation of a car to an installation floor of a control device according to an embodiment of the present invention.
In step S1, the car 104 is positioned so that the car upper surface 104a coincides with the floor level 1FL of an upper floor (e.g., 1 floor), and an operator lifts the car upper surface 104a from the hall floor.
In step S2, the car upper surface maintenance signal (car upper maintenance signal) or the 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 generated 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 emitted by unfolding the folded handrail. In addition to these signals, signals generated when the hall side door (door) is opened and customer specification information may be used as trigger signals.
If the maintenance mode is shifted, in step S3, the flooding height information 411 and the floor height information 412 are compared to determine the setting floor (specific floor) of the control device 102.
In step S4, the layer height of the specific layer is determined as the setting position (a) of the control device 102. That is, in the present 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 lowermost end of the control device 102 coincides with the floor level of the specific floor.
In step S5, as the obstacle information 414, the car height Hc and the handrail type of the product specification are used, and the handrail height dimension (B) is determined from the car height Hc and the handrail type.
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 specifying maintenance content, and for example, the maintenance content such as insulation test and component replacement is input as the work content information 431. The height adjusted by the position adjustment (maintenance height automatic adjustment operation) of the car 104 is changed in accordance with the maintenance work. The operation (UP/DN) signal corresponds to a start switch signal, and transmits completion of the input operation to the control device 102, and starts an operation mode (maintenance operation mode) among the maintenance modes. The maintenance operation mode is a mode for actually lifting and lowering the car 104, and includes an input mode for inputting 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 particular floor determined as the set position of the control 102, and (B) is the armrest height dimension determined as an obstacle. The height position including the position adjustment amount of the upper surface 104a of the car 104 is determined by calculating the positional relationship of (a) and (B). In the determination of the height position including the position adjustment amount, the maintenance target member and the height position thereof are determined based on the specific maintenance signal (maintenance operation content) input in step S6.
In step S8, it is determined whether the maintenance target member and the armrest are at the same height. When the maintenance target component (maintenance target position) and the armrest of the control device 102 are at the same height, the armrest 104b becomes a hindrance to access to the maintenance target component (maintenance target position) during maintenance, and the process advances to step S9. If the maintenance target component (maintenance target position) and the armrest of the control device 102 are not the same height, the armrest 104b does not obstruct access to the maintenance target component (maintenance target position) during maintenance, and the process proceeds to step S10.
In step S9, the position of the upper surface 104a of the car is automatically adjusted to a position where it does not hinder the maintenance work, and the process proceeds to step S11. In this case, the position of the upper surface 104a of the car is automatically adjusted from the position specified in (a) to a position where it does not hinder the maintenance operation.
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 positional adjustment with respect to the obstacle.
In step S11, the worker performs maintenance work.
In the present embodiment, the upper surface 104a of the car can be automatically positioned at the control device 102 disposed at a different height position for each elevator apparatus 100 in order to avoid flooding, and in the case where there is an obstacle such as the handrail 104b, the upper surface 104a of the car can be automatically positioned at a height position avoiding the obstacle. For example, when the insulation test of the control device 102 is performed, the car upper surface 104a serving as the work table can be moved to a height position such that the insulation test portion of the control panel is avoided from the armrest 104 b. That is, in the present embodiment, even when the floor of the control device 102 is different for each elevator device, the elevator device is provided such that the car 104 is positioned and stopped so that the car upper surface 104a coincides with the floor level of the floor of the control device 102. Thus, in the elevator apparatus of the present embodiment, maintenance work efficiency can be improved.
