In an elevator device according to the present invention, a control panel 1 includes an incoming panel section 12 to which electric wires 201, 203 installed from a hoist and a governor are connected, and the electric wires 201, 203 are installed as traversing the inside of the control panel 1 from one side to the other side in the width direction W of the control panel 1.

Description

Elevator Equipment

The present invention relates to elevator equipment, and in particular to the configuration of a control panel used in an elevator equipment.

Patent Document 1 describes a control device that is installed in the hoistway of an elevator system without a machine room and has operation control devices, power receiving devices, a power storage device, etc. mounted on a control panel, in which the control panel is installed on the wall of the hoistway so that the bottom surface of the control panel's housing is positioned above the top surface of the car stopped at the lowest floor (see abstract).

JP 2010-208764 A

In a configuration in which the control panel is installed at the bottom of the elevator shaft, as in the elevator system of Patent Document 1, the electric wires (electrical wiring including power lines, signal lines, etc.) of the hoist and the equipment installed in the hoist can be routed to the control panel through a pit section formed in the bottom of the hoistway. However, in an elevator system in which the hoist and control panel are installed at the top of the hoistway, it is not possible to route the wires through the pit section, making it difficult to route the wires from one side of the control panel to the other side. If it is possible to ensure sufficient gaps on the back of the control panel, the gaps on the back can be used to route the wires. However, if it is difficult to ensure sufficient gaps on the back of the control panel due to the miniaturization of the hoistway, it becomes difficult to route the wires using the gaps on the back.

The object of the present invention is to provide an elevator system with a control panel that reduces the constraints imposed by the size of the elevator shaft and improves the freedom of wiring.

In order to solve the above problems, the elevator device of the present invention comprises:
In an elevator device including a car, a hoist, a governor, and a control panel,
The control panel has a power receiving panel section to which each electrical wiring laid from the hoisting machine and the governor is connected,
The electrical wiring is laid across the inside of the control panel from one side to the other in the width direction of the control panel.

According to the present invention, it is possible to provide an elevator system having a control panel which reduces the constraints imposed by the size of the hoistway and improves the freedom of wiring.
Problems, configurations and effects other than those described above will become apparent from the following description of the embodiments.

Below, an embodiment of the present invention will be explained with reference to the drawings.

The overall configuration of the elevator device 100 will be outlined with reference to Figures 1 and 2. Figure 1 is a cross-sectional view parallel to the vertical direction, showing the configuration of the elevator device 100 according to one embodiment of the present invention. Figure 2 is a cross-sectional view parallel to the horizontal direction, showing the configuration of the elevator device 100 according to one embodiment of the present invention.

As shown in FIG. 1, the elevator device 100 includes a car 104 and a counterweight 105 that move up and down in a hoistway 101, a hoist 102 around which a main rope 107 that connects the car 104 and the counterweight 105 is wound, a guide rail 109 that is erected in the hoistway 101 and guides the car 104 and the counterweight 105 as they move up and down, a control panel 1 that controls the elevator device 100, and a governor 111 that detects the ascent and descent speed of the car 104.

The car 104 and counterweight 105 are installed inside a hoistway 101 installed in a building, and are suspended in a bucket-like manner by a main rope 107. The car 104 is electrically connected to the control panel 1 by a tail cord 108, and receives power via the tail cord 108, and exchanges control signals and various other signals with the control panel 1. A shock absorber 106 is installed on the bottom of the hoistway 101, below the car 104 and counterweight 105.

The hoisting machine 102 is supported by a machine beam 102a and is disposed at the top of the hoistway 101, and the control panel 1 is disposed near the hoisting machine 102. That is, the control panel 1 is also disposed at the top of the hoistway 101. In this embodiment, an example is shown in which the hoisting machine 102 and the control panel 1 are disposed at the top of the hoistway 101, but the positions of the hoisting machine 102 and the control panel 1 are not limited to the top of the hoistway 101. However, the control panel 1 in this embodiment has a configuration that is effective when the hoisting machine 102 and the control panel 1 are disposed at the top of the hoistway 101. The configuration of this control panel 1 will be described in detail later.

The guide rail 109 is fixed to the inner wall (hoistway wall) 101a of the hoistway 101 by a rail bracket 110.

As shown in FIG. 2, the car 104 has a car door 104a on the side facing the elevator hall 112, and an entrance door 20a facing the car door 104a is provided on the elevator hall 112 side. A space is provided between the other sides of the car 104, excluding the side on which the car door 104a is provided, and the elevator shaft wall 101a, in which equipment (equipment within the elevator shaft) such as the hoist 102 and the control panel 1 are disposed. A posidetector 104c for detecting the position of the car 104 is provided on the car 104 so as to protrude from one side position of the car 104 towards the elevator shaft wall 101a.

The elevator device 100 in this embodiment is a traction type, in which the hoist 102 frictionally drives the main rope 107, raising and lowering the car 104 along the car guide rail 109A, and raising and lowering the counterweight 105 along the counterweight guide rail 109B.

The guide rails 109 are erected in the vertical direction along the elevator shaft wall 101a. The guide rails 109 include a car guide rail 109A and a counterweight guide rail 109B. The car guide rail 109A is a guide rail for the passenger car 104, and has a pair of guide rails. The counterweight guide rail 109B is a guide rail for the counterweight 105, and has a pair of guide rails.

When viewed from the elevator hall 112 side, the pair of car guide rails 109A are arranged separately on the hoistway wall 101a on both the left and right sides of the car 104. One of the pair of car guide rails 109A is fixed to the hoistway wall 101a by a shared rail bracket 110C, and the other is fixed to the hoistway wall 101a by a car rail bracket 110A. The shared rail bracket 110C is a rail bracket shared between the car guide rail 109A and the counterweight guide rail 109B. The car rail bracket 110A is a rail bracket dedicated to the car guide rail, provided for the car guide rail 109A.

The pair of counterweight guide rails 109B are arranged in the space in which the counterweight 105 is arranged. That is, the pair of counterweight guide rails 109B are arranged in the same space on either the left or right side of the car 104 when viewed from the elevator hall 112 side. One of the pair of counterweight guide rails 109B is fixed to the hoistway wall 101a by a common rail bracket 110C, and the other is fixed to the hoistway wall 101a by a counterweight rail bracket 110B. In this embodiment, the common rail bracket 110C is fixed to the hoistway wall 101a facing the left side (left side) of the car 104 when viewed from the front, and the counterweight rail bracket 110B is fixed to the hoistway wall 101a facing the back of the car 104.

Hereinafter, in the case of the car guide rail 109A and the counterweight guide rail 109B, when there is no need to distinguish between "for car" and "for counterweight", they will be referred to simply as the guide rail 109, omitting "for car" and "for counterweight". Also, in the case of the car rail bracket 110A, the counterweight rail bracket 110B and the shared rail bracket 110C, when there is no need to distinguish between "shared", "for counterweight" and "for car", they will be referred to simply as the rail bracket 110, omitting "shared", "for counterweight" and "for car".

The hoist 102 is disposed in a space formed on the left side of the car 104 when viewed from the elevator hall 112 side. In this embodiment, a governor 111 having a governor encoder 111a is disposed in the space on the same side as the hoist 102. The hoist 102 is fixed to the hoistway wall 101a by the machine beam 102a described in FIG. 1, but by installing the machine beam 102a between the car guide rail 109A and the counterweight guide rail 109B, the hoist 102 is fixed to the hoistway wall 101a via the car guide rail 109A and the counterweight guide rail 109B.

The control panel (first control panel) 1 is disposed in a space formed on the right side of the car 104 when viewed from the elevator hall 112 side. The control panel 1 is fixed to the elevator shaft wall 101a by a control panel bracket (first control panel bracket) 1a. In this case, the control panel bracket 1a is fixed to the car guide rail 109A, and the control panel 1 is fixed to the elevator shaft wall 101a via the car guide rail 109A. The tail cord 108 described in FIG. 1 is connected to the control panel 1, and a tail cord support 108b that supports the tail cord 108 is provided near the control panel 1. The tail cord support 108b is fixed to the car guide rail 109A to which the control panel bracket 1a is fixed by the tail cord support bracket 108a.

The elevator device 100 of this embodiment includes a control panel 1 as a standard control panel, and includes a second control panel 2 in addition to the control panel (first control panel) 1. The second control panel 2 is fixed to the hoistway wall 101a by a second control panel bracket 2a. In this case, the control panel bracket 2a is fixed to the counterweight guide rail 109B, and the control panel 2 is fixed to the hoistway wall 101a via the counterweight guide rail 109B.

The second control panel (optional panel) 2 is a control panel that implements control components required as customer optional functions in addition to the basic control functions of the elevator device 100. For this reason, the second control panel 2 may not be provided.

The configuration of the control panel 1 will be described with reference to Figure 3. Figure 3 is an external view of the control panel 1 of an elevator device 100 according to one embodiment of the present invention.

The control panel 1 has a main circuit board section 11, a power receiving board section 12, a signal board section 13, a regenerative resistor board section 14, and a battery board section 15.

The main circuit board section 11 is a control panel section that implements main circuit elements and control boards for controlling the motor and brake of the hoisting machine 102. The main circuit board section 11 includes a power supply panel section 16. The power supply panel section 16 is a control panel section that implements a control power source for controlling the operation of the elevator device 100, including the speed and position of the car 104.

The power receiving panel section 12 is a control panel section that includes a terminal block for receiving the power source for the hoisting machine 102, a circuit breaker and electromagnetic contactor for turning the power source on and off, and a filter circuit for removing noise superimposed on the power line.

The signal panel unit 13 is a control panel unit that implements a control board and the like for controlling the operation of the elevator device 100, including the speed and position of the car 104.

The regenerative resistor panel section 14 is a control panel section that is equipped with resistors for consuming the regenerative current generated when the elevator device 100 is in regenerative operation as thermal energy.

The battery panel unit 15 is a control panel unit that has a battery power source installed to operate the car 104 to the nearest floor in the event of a power outage, and to move the car 104 by using a weight imbalance between the car 104 and the counterweight in the event of a breakdown in the elevator device 100, thereby "releasing the brakes" to rescue passengers.

In the control panel 1, the main circuit board section 11 and the power receiving board section 12 are arranged side by side in parallel. The regenerative resistor board section 14 is arranged above the main circuit board section 11 and the power receiving board section 12, and the signal board section 13 is arranged below the main circuit board section 11 and the power receiving board section 12. The battery board section 15 is arranged below the signal board section 13. In other words, the control panel 1 has the regenerative resistor board section 14, the main circuit board section 11, the power receiving board section 12, the signal board section 13, and the battery board section 15, and the main circuit board section 11 and the power receiving board section 12 are arranged in parallel in the horizontal direction. The regenerative resistor board section 14, the main circuit board section 11 and the power receiving board section 12, the signal board section 13, and the battery board section 15 are arranged in the following order from top to bottom: regenerative resistor board section 14, main circuit board section 11 and the power receiving board section 12, the signal board section 13, and the battery board section 15.

The regenerative resistor panel section 14 is a control panel section that is prone to generating heat, and by placing it at the top among the main circuit panel section 11, the power receiving panel section 12, the signal panel section 13, the regenerative resistor panel section 14, and the battery panel section 15, the thermal impact on other control panel sections can be reduced.

In particular, in the control panel 1 of this embodiment, the regenerative resistor panel section 14 is arranged above the main circuit panel section 11, and the signal panel section 13 is arranged below the main circuit panel section 11. That is, the regenerative resistor panel section 14, the main circuit panel section 11, the signal panel section 13, and the battery panel section 15 are arranged in a row (series) from the top to the bottom of the control panel 1 in this order. In other words, the regenerative resistor panel section 14, the main circuit panel section 11, the signal panel section 13, and the battery panel section 15 are arranged in a row (series) in the vertical direction of the control panel 1. The power receiving panel section 12 is arranged so as to protrude horizontally (sideways) from the row of the regenerative resistor panel section 14, the main circuit panel section 11, the signal panel section 13, and the battery panel section 15 arranged in series. This creates a space below the power receiving panel section 12.

By forming a space below the power receiving panel section 12, this space can be used to connect electrical wiring to the power receiving panel section 12 from below, making it easy to route the electrical wiring. For example, the power supply lead-in wire 19 for the hoisting machine 102 is connected to the power receiving panel section 12 from the space formed below the power receiving panel section 12, making it easy to route the lead-in wire 19.

In the past, the functions of the power receiving unit 12 were sometimes distributed between the main circuit board unit 11 and the signal board unit 13. In contrast to this, in this embodiment, the functions of the power receiving unit are consolidated in the power receiving unit 12. In addition, the power supply board unit 16 is placed in the main circuit board unit 11. It is preferable to place the power receiving board unit 12 below the main circuit board unit 11. In this case, the power supply board unit 16 may be placed closer to the lower end of the main circuit board unit 11 than the upper end, but it is sufficient that it is placed below the inspection height (1650 mm) described below.

The horizontal side edges of each control panel section, the regenerative resistor panel section 14, the main circuit panel section 11, the power receiving panel section 12, the signal panel section 13, and the battery panel section 15, are provided with fixing

sections

14a, 11a, 12a, 13a, and 15a that fix the control panel 1 to the control panel bracket 1a as shown in FIG. 5. The fixing

sections

14a, 11a, 12a, 13a, and 15a are configured as flange sections (control panel flange sections) that protrude to the side of the control panel 1.

Fixed parts

14a, 13a, 15a are provided on both side edges of the regenerative resistor panel section 14, the signal panel section 13, and the battery panel section 15. Fixed part 11a is provided on one side edge of the main circuit panel section 11 opposite the side of the power receiving panel section 12. Fixed part 12a is provided on one side edge of the power receiving panel section 12 opposite the side of the main circuit panel section 11.

Each control panel section is provided with a lid, but the lid of the signal panel section 13 is divided into two

lid sections

13b and 13c.

The configuration of the main circuit board section 11 and the power receiving board section 12 will be described with reference to Figure 4. Figure 4 is a perspective view of the main circuit board section 11 and the power receiving board section 12 of the control panel 1 shown in Figure 3.

The main circuit board section 11 and the power receiving board section 12 are housed in a single case 17 having two

chambers

17d, 17e separated by a partition wall 17a, and are arranged separately in the two

chambers

17d, 17e. The main circuit board section 11 and the power receiving board section 12 are then covered by a single lid 17b. In other words, the lid 17b is configured to cover both the control board sections of the main circuit board section 11 and the power receiving board section 12.

The main circuit board section 11 and the power receiving board section 12 are provided with connecting sections 17c for connecting with the regenerative resistor board section 14 and the signal board section 13 arranged above and below. Such connecting sections 17c are also provided on the other

control board sections

14a, 13a, and 15a, and each of the

control board sections

14a, 11a, 12a, 13a, and 15a is configured to be connectable to each other.

The mounting structure (fixing structure) of the control panel 1 will be described with reference to Figure 5. Figure 5 is a diagram showing the mounting structure of the control panel 1 shown in Figure 3.

In this embodiment, the control panel 1 is fixed to the elevator shaft wall 101a by a car guide rail 109A, which is fixed to the elevator shaft wall 101a by a car rail bracket 110A. For this reason, a control panel bracket 1a is fixed to the car guide rail 109A, and the control panel 1 is fixed to the car guide rail 109A via the control panel bracket 1a.

The tail cord 108 from the car 104 is connected to the signal panel section 13 as shown in FIG. 5. The tail cord 108 is supported near one end connected to the signal panel section 13 by a tail cord support 108b fixed to a tail cord support bracket 108a. The tail cord support bracket 108a is fixed to the car guide rail 109A, and the tail cord support 108b is fixed to the elevator shaft wall 101a via the tail cord support bracket 108a and the car guide rail 109A.

In the control panel 1, a space is formed on the side of the signal panel section 13 below the power receiving panel section 12. The tail cord 108 connected to the signal panel section 13 is positioned using this space, so that it can be positioned without protruding significantly to the side of the control panel 1.

In this embodiment, the control panel 1 is placed near the top floor. FLt in FIG. 5 indicates the floor height position of the floor where the car top 104b of the car 104 is positioned when inspecting the control panel 1. In this embodiment, FLt is the floor height position of the top floor. Also, OH represents the distance between the floor height position FLt of the top floor and the upper end (ceiling surface) 101b of the elevator shaft 101, i.e., the height dimension of the elevator shaft space formed above the floor height position FLt of the top floor.

The layout of the control panel 1 will be described with reference to FIG. 6. FIG. 6 is a comparison diagram with a comparative example to explain the characteristics of the layout of the control panel 1 shown in FIG. 3.

Figures 6(a) and (b) show a control panel 1' in a comparative example. In the control panel 1' in the comparative example, from top to bottom, a battery panel section 15', a regenerative resistor panel section 14', a signal panel section 13', and a main circuit panel section 11' are arranged. The power supply panel section 16, which is included in the main circuit panel section 11 in this embodiment, is included in the signal panel section 13' in the control panel 1'. Also, the power receiving section 12 in this embodiment is distributed between the main circuit panel section 11' and the signal panel section 13' in the control panel 1'.

As shown in Figure 6(a), if the control panel 1' of the comparative example is placed below the upper end 101b of the elevator shaft 101, the main circuit board section 11' will be located below the floor height FLt of the top floor. The parts of the control panel 1' that are inspected during statutory periodic inspections (statutory inspections) such as insulation tests (hereinafter referred to as inspection parts) are the signal board section 13' and main circuit board section 11', which are indicated by the dashed line T. In this case, the main circuit board section 11' of the inspection part T is located below FLt.

During regular inspection of the control panel 1, the car top 104b (see FIG. 1) of the car 104 is positioned at FLt, and an operator climbs onto the car top 104b to perform the inspection work. That is, in the elevator device 100 of this embodiment, the control panel 1 and the hoist 102 are disposed at the top of the hoistway 101, and the control panel 1 is inspected by positioning the car top 104b of the car 104 at the height position FLt of the top floor, and an operator performs the inspection work from the car top 104b.

In this case, if the control panel 1' and FLt are positioned as shown in Figure 6(a), workers will not be able to inspect the main circuit board section 11' from above the car 104b. For this reason, in Figure 6(a), it will be necessary to move the car 104 to a height position where the inspection area of the main circuit board section 11' can be inspected, which will complicate the inspection work and lengthen the inspection time.

FIG. 6(b) shows an example in which the main circuit board section 11' is positioned above FLt so that it can be inspected from above the car 104b. In FIG. 6(b), the upper part of the control panel 1' (battery panel section 15') is positioned above the upper end 101b of the hoistway 101, and the control panel 1' will not fit at the top of the hoistway 101. Also, in FIG. 6(b), the power panel section 16 included in the signal panel section 13' is positioned at a height that allows inspection from above the car 104b without using a stepladder or the like (set to 1650 mm in this embodiment).

In this embodiment, by using a control panel 1 in which the main circuit board section 11, the power receiving board section 12, the signal board section 13, the regenerative resistor board section 14, and the battery board section 15 are arranged as described in FIG. 3, the inspection area T is located above the car top 104b and within the height range that can be inspected, as shown in FIG. 6(c).

As mentioned above, in the control panel 1' of the comparative example, the power receiving unit 12 of this embodiment is distributed between the main circuit board unit 11' and the signal board unit 13', and the power supply board unit 16 is included in the signal board unit 13'. In this embodiment, the power receiving unit on the signal board unit 13' side is consolidated into the power receiving unit 12 of this embodiment, and the power supply board unit 16 is moved from the signal board unit 13' to the main circuit board unit 11, so that the inspection areas within the signal board unit 13 are concentrated at the upper part of the signal board unit 13. In Figure 6(c), the lower part of the signal board unit 13 is located below FLt, but this lower part is not subject to regular inspections and does not affect workability during regular inspections.

In the main circuit board section 11 of this embodiment, the power receiving section on the main circuit board section 11' side is consolidated into the power receiving section 12 of this embodiment, and the power supply board section 16 is disposed at the bottom of the main circuit board section 11, so that the inspection parts within the main circuit board section 11 are concentrated at the bottom of the main circuit board section 11. In FIG. 6(c), the upper part of the main circuit board section 11 is located above the inspectable height (1650 mm), but this upper part is not subject to regular inspections and does not affect the workability during regular inspections.

As described above, in this embodiment, the inspection areas of the main circuit board section 11, the power receiving board section 12, and the signal board section 13 can be inspected with the car top 101b of the car 104 positioned at FLt. This prevents the inspection work from becoming complicated, and improves workability.

The arrangement of the equipment, such as the hoist 102 and the control panel 1, of the elevator system 100 will be described with reference to FIG. 7. FIG. 7 is a diagram showing an example of the arrangement of equipment in the elevator system 100 according to one embodiment of the present invention. Note that FIG. 3 illustrates the main circuit board section 11 and the power receiving board section 12 within the control panel 1.

Figure 7(c) shows an example in which the control panel 1, hoist 102, and counterweight 105 are arranged in the same way as in Figure 2. The car guide rails 109A and counterweight guide rails 109B are also arranged in the same way as in Figure 2. Note that Figure 7 illustrates the rope end 107a on the car 104 side. The rope end 107a is arranged on the side of the hoistway wall opposite the hoistway wall on the side where the hoist 102 and counterweight 105 are arranged, sandwiching the car 104.

Figure 7(a) shows an example in which the arrangement of the control panel 1 has been changed from that of Figure 2 (Figure 7(c)). In this case, the control panel 1 is arranged in the space on the rear side of the car 104 (opposite the car door 104a side). In this case, it is preferable that the control panel 1 is arranged close to the wall of the elevator shaft 101 on the side where the hoisting machine 102 is arranged, that is, the wall on the left side when viewed from the elevator hall 112 side. This makes it possible to shorten the electrical wiring between the control panel 1 and the hoisting machine 102. Although not shown in Figure 7(a), the control panel bracket 1a for fixing the control panel 1 is preferably fixed to the counterweight guide rail 109B arranged near the control panel 1. The rope end 107a is arranged in the same way as in Figure 7(c).

Figure 7(b) shows an example in which the arrangement of the hoist 102 and counterweight 105 has been changed from that of Figure 7(a). In this case, the hoist 102 and counterweight 105 are arranged on the right-hand hoistway wall side as viewed from the elevator hall 112 side. In this case, the counterweight guide rail 109B is also arranged on the same side as the counterweight 105. The control panel 1 is also arranged close to the right-hand hoistway wall as viewed from the elevator hall 112 side. The arrangement of the main circuit board section 11 and the power receiving section 12 has also been swapped from that of Figure 7(a).

Although not shown in Figure 7(b), the position of the common rail bracket 110C is also changed in conjunction with the change in the position of the counterweight guide rail 109B, and is now positioned on the same side as the counterweight 105. In this case, similar to the case of Figure 7(a), the control panel bracket 1a for fixing the control panel 1 may be fixed to the counterweight guide rail 109B positioned near the control panel 1. The rope end 107a is positioned on the side of the hoistway wall facing the hoistway wall on the side where the hoist 102 and counterweight 105 are positioned, and is positioned on the opposite side to the side where it is positioned in Figure 7(a).

Figure 7(d) shows an example in which the control panel 1 and rope end 107a, and the hoist 102 and counterweight 105 are arranged in a reversed arrangement from that shown in Figure 7(c). In this case, the counterweight guide rail 109B is also arranged on the same side as the counterweight 105. Although not shown in Figure 7(d), the shared rail bracket 110A is arranged on the same side as the counterweight 105. In this example, the control panel bracket 1a for fixing the control panel 1 is fixed to the car guide rail 109A arranged near the control panel 1, as in the case of Figure 7(c), but is fixed to the car guide rail 109A on a different side (opposite side) from that in the case of Figure 7(c).

As shown in FIG. 7, the arrangement of the control panel 1, hoist 102, and counterweight 105 can be changed from that of FIG. 2. By changing the arrangement of the control panel 1, hoist 102, and counterweight 105, the arrangements of the car guide rail 109A and counterweight guide rail 109B, the car rail bracket 110A, counterweight rail bracket 110B, and shared rail bracket 110C are also changed as appropriate. In addition, by changing the arrangement of the control panel 1, car guide rail 109A, and counterweight guide rail 109B, the guide rail 109 that fixes the control panel bracket 1a is also changed as appropriate.

In addition, although FIG. 7 illustrates the layout of the main circuit board section 11 and the power receiving board section 12, the layout of the main circuit board section 11 and the power receiving board section 12 is not limited to the layout in FIG. 7, and the positions of the main circuit board section 11 and the power receiving board section 12 in FIG. 7 may be interchanged.

In addition, in the configurations of Figures 7(c) and (d), since devices such as the control panel 1 are not arranged on the rear side of the car 104, a car door 104a can also be provided on the rear side of the car 104.

Regular inspection of the control panel 1 will be described with reference to Figure 8. Figure 8 is a diagram showing regular inspection of the control panel 1 shown in Figure 3.

The driving devices such as the hoist 102 and the control panel 1 are concentrated at the top of the elevator shaft 1, so there is a lot of competition for space for each piece of equipment, and the mounting height of each piece of equipment is also limited. In order to improve maintainability, the inspection area for periodic inspections of the control panel 1 is located above FLt and up to a height that allows inspection (1650 mm) when the car top 101b of the car 104 is positioned at FLt.

Furthermore, in this embodiment, the governor 111 and the inspection area of the control panel 1 are positioned above FLt and within a range up to an inspectable height (1650 mm). That is, the elevator device 100 in this embodiment is equipped with a governor 111 for detecting the ascent and descent speed of the car 104, and the governor 111 is positioned below the upper ends of the main circuit board section 11 and the power receiving board section 12. This makes it possible to carry out maintenance and inspection work on the governor 111 and the control panel 1 in parallel.

Furthermore, when performing maintenance on the hoist 102 from above the car 104b, it is necessary to shut off the power switch 102b of the hoist 102. In this embodiment, by providing the power switch 102b on the power receiving panel 12, it is not necessary to provide a new power switch box on the hoist 102. Furthermore, the hoist 102 is often located near the top end 101b of the top of the hoistway 101, at a position higher than the height at which it can be inspected (1650 mm). Even in such cases, by providing the power switch 102b on the power receiving panel 12, it is possible to position the power switch 102b within the range of the height at which it can be inspected (1650 mm), making it easier to shut off the power switch 102b of the hoist 102.

In this embodiment, the embodiment in which the driving devices such as the hoist 102 and the control panel 1 are disposed at the top of the elevator shaft 1 has been described, but the effects of the above-mentioned embodiment can be effectively utilized even in the embodiment in which the driving devices such as the hoist 102 and the control panel 1 are disposed at a location other than the top of the elevator shaft 1. For example, if the control panel 1 is disposed at the height of the second floor of the elevator shaft 101, FLt will be set to the height position of the second floor. In this case, depending on the size of the car 104, the car top 104b may not be able to be lowered to FLt. Even in such a case, by adopting the configuration of the control panel 1 of this embodiment, the inspection portion of the control panel 1 can be disposed within a range of height (1650 mm) that can be inspected from the car top 104b of the car 104 lowered to the lowest position.

The wiring structure to the control panel 1 will be described with reference to Figures 9 and 10. Figure 9 is a schematic diagram showing the wiring structure to the control panel in this embodiment. Figure 10 is a cross-sectional view of the wiring structure in Figure 10. The height direction H, width direction W, and thickness direction D of the control panel 1 are defined as shown in Figure 9.

In an elevator system in which the control panel is installed on the lowest floor, the electric wires (electric wire motor wiring, governor encoder wiring, tail cord, branch cable, etc.) of the equipment in the elevator shaft, including the hoist 102, can be connected to the control panel 1 through the pit. In the case of an elevator system in which the hoist 102 is installed at the top of the elevator shaft 101, the control panel 1 is also installed at the top, so the electric wires that run across the width (left and right) of the control panel 1 must be routed through the space behind the control panel 1. However, for example, when the dimensions of the elevator shaft are small, it may not be possible to secure sufficient space behind the control panel 1. The electric wires can be extended to the ceiling of the elevator shaft 101, but this would result in unnecessarily long electric wires, leading to increased costs and construction man-hours.

An example of the electric wires of the equipment in the elevator will be described with reference to FIG. 2. 201 is an electric wire that connects the motor of the hoist 102 to the control panel 1, and is called the hoist motor wiring (hoist motor electric wire). 202 is an electric wire that connects the brake of the hoist 102 to the control panel 1, and is called the brake wiring (brake electric wire). 203 is an electric wire that connects the encoder (governor encoder) 111a of the governor 111 to the control panel 1, and is called the governor encoder wiring (governor encoder electric wire).

As shown in FIG. 2, these electrical wiring (electrical wires) 201-203 are routed from the hoistway side (hoistway wall) 101a1 side where the hoistway 102 and governor 111 are arranged, through the entrance/exit sill 20b (see FIG. 8) and pocket area provided on the hoistway wall 101a2 side facing the car door 104a of the car 104, to the hoistway side (hoistway wall) 101a3 side where the control panel 1 is arranged. In addition to the electrical wiring 201-203, FIG. 9 also illustrates the building power supply wiring (building power supply electric wire) 204. The building power supply wiring 204 is a power supply wiring that is pulled into the inside of the hoistway 101 from an opening 101c formed in the hoistway wall 101a.

The hoist motor wiring 201 and the building power supply wiring 204 are made of thick wires with a larger diameter than the brake wiring 202 and the governor encoder wiring 203.

Each of the electrical wiring 201-204 is wired through the inside of the control panel 1 from the outside of one side surface to the outside of the other side surface in the width direction. That is, in this embodiment, each of the electrical wiring 201-204 is inserted into the inside of the control panel 1 from the side 1d opposite the side on which the power receiving panel section 12 is provided, and is drawn out to the outside of the control panel 1 from the side 1e on the side on which the power receiving panel section 12 is provided. For this reason, the control panel 1 is provided with a wiring space 18 in which each of the electrical wiring 201-204 is wired. In addition, an opening 1b is provided in the side (side wall) 1d of the control panel 1, and an opening 1c is provided in the side (side wall) 1e. The

openings

1b and 1c form insertion sections through which each of the electrical wiring 201-203 is inserted.

In this embodiment, the wiring space 18 is provided at the top of the signal panel section 13, i.e., at the end on the main circuit panel section 11 side. In this case, the wiring space 18 is configured as part of the signal panel section 13, but it may also be configured as a wiring panel section (box) dedicated to wiring between the signal panel section 13 and the main circuit panel section 11. In any case, the wiring space 18 can be considered to be configured between the signal panel section 13 and the main circuit panel section 11. In other words, the control panel 1 has the wiring space 18 between the signal panel section 13 and the main circuit panel section 11.

Each of the electrical wiring 201-204 may be configured to be pulled directly into the inside of the power receiving panel unit 12, but in this embodiment, the electrical wiring (electric wires) 201-12 to 204-12 connected to each of the electrical wiring 201-204 are pulled out from the side of the power receiving panel unit 12. The power receiving panel unit side pull-out wiring 201-12 to 204-12 pulled out from the side of the power receiving panel unit 12 are connected to each of the electrical wiring 201-204 by connector C1. In other words, the hoist motor wiring is connected to the power receiving panel unit side pull-out wiring (power receiving panel unit side hoist motor wiring) 201-12 by connector C1. The brake wiring 202 is connected to the power receiving panel unit side pull-out wiring (power receiving panel unit side brake wiring) 202-12 by connector C1. The governor encoder wiring is connected to the power receiving panel side draw-out wiring (power receiving panel side governor encoder wiring) 203-12 by connector C1. The building power wiring 204 is connected to the power receiving panel side draw-out wiring (power receiving panel side building power wiring) 204-12 by connector C1.

By pulling out the receiving board side pull-out wiring 201-12 to 204-12 from the receiving board section 12, the electrical wiring 201 to 204 can be inserted into the wiring space 18 and easily connected to the receiving board side pull-out wiring 201-12 to 204-12. This makes it easy to electrically connect the electrical wiring 201 to 204 to the control panel 1.

As described above, the electrical wiring 201-203 is routed through the entrance/exit sill 20b. In FIG. 8, the entrance/exit sill 20b is located near the floor height position FLt. When the electrical wiring 201-203 routed through the entrance/exit sill 20b is laid from one side to the other in the width direction (left/right direction) W of the control panel 1 above or below the control panel 1, it is necessary to make a large detour around the control panel 1 in the vertical direction, which increases the length of the electrical wiring 201-203.

According to this embodiment, even if there is not enough space on the rear side of the control panel 1, by traversing the inside of the control panel 1, it is not necessary to make a large detour around the control panel 1 in the vertical direction, and it is possible to prevent the length of the electrical wiring 201-203 from becoming too long. This allows the length of the electrical wiring 201-203 to be standardized without being made longer than necessary, making it possible to reduce material costs and construction costs. If the standardized length of the electrical wiring is too long, the excess part can be stored in the wiring space 18, improving workability.

In addition, the constraints imposed by the size of the elevator shaft 101 can be alleviated, improving the degree of freedom in wiring the electrical wiring 201-203.

The effect of this embodiment, in which the length of the electrical wiring 201-204 can be prevented from increasing by having the electrical wiring 201-204 cross the inside of the control panel 1, is not limited to elevator systems in which the control panel 1, hoist 102, governor 111, etc. are located at the top of the hoistway 100, but can also be obtained in elevator systems located at the bottom of the hoistway 100 or in elevator systems located at other locations on the hoistway 100.

Furthermore, by storing maintenance tools in the wiring space 18, workers do not need to carry maintenance tools with them.

In addition, in a configuration in which the electrical wiring 201-204 and the outgoing wiring 201-12-204-12 on the power receiving panel side are connected by the connector C1, the connector C1 is disposed inside the control panel 1, so that the connector C1 can be protected from dirt and the like. This makes it possible to prevent poor connections between the electrical wiring 201-204 and the outgoing wiring 201-12-204-12 on the power receiving panel side.

Electrical wiring 201 to 204 and electrical wiring 201-12 to 204-12 are electrical wiring that cross the control panel 1 in the width direction, and may be described as crossing electrical wiring. In addition to the above, the electrical wiring for the equipment in the elevator shaft includes building power lines, RE lines, etc., and these electrical wirings can also be wired to the control panel 1 in the same way as the above-mentioned electrical wiring.

As shown in FIG. 9,

electrical wiring

205a, 205b that connects between the main circuit board section 11 and the signal board section 13 is laid in the wiring space 18 of the control panel 1, and the

electrical wiring

205a, 205b is laid vertically within the wiring space 18. The

electrical wiring

205a, 205b is electrical wiring laid inside the control panel 1, and may be described as electrical wiring inside the control panel.

As shown in FIG. 10, partition members 18a1-18a4 are provided in the wiring space 18 to separate the area in which the internal

electrical wiring

205a, 205b of the control panel is laid from the area in which the transverse electrical wiring 201-204, 201-12-204-12 is laid. As a result, the area in which the internal

electrical wiring

205a, 205b of the control panel is laid is limited to the four corners, including the corners, of the rectangular horizontal cross section of the control panel 1 (cross section shown in FIG. 10).

The installation range of the transverse electrical wiring 201-204, 201-12-204-12 and the installation range of the

electrical wiring

205a, 205b inside the control panel are separated by the partition members 18a1-18a4, so that when the transverse electrical wiring 201-204, 201-12-204-12 are inserted into the wiring space 18 from the

openings

1b, 1c, the transverse electrical wiring 201-204, 201-12-204-12 can be prevented from interfering with the

electrical wiring

205a, 205b inside the control panel, and wiring work can be performed efficiently.

Furthermore, the four corners, including the corners, are not suitable for laying the transverse electrical wiring 201-204, 201-12-204-12. By setting the area unsuitable for laying the transverse electrical wiring 201-204, 201-12-204-12 as the area for laying the

electrical wiring

205a, 205b inside the control panel, the space within the wiring space 18 can be effectively utilized.
