Description

[Technical field]

[0001] The present invention relates to an elevator system, and more particularly to the configuration of a control panel used in an elevator system. [Background technology]

[0002] Conventionally, there is known a machine room-less elevator device that does not have a machine room in which a hoisting machine is arranged, but has the hoisting machine arranged in the hoistway. Patent Document 1 describes a machine room-less elevator device that has a normal control panel (hereinafter referred to as the control panel) arranged on the inner wall surface at the top of the hoistway. This control panel has a vertically elongated structure that extends in the vertical direction (see paragraph 0027 and Figure 4). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2018-52648 A Summary of the Invention [Problem to be solved by the invention]

[0004] In a control panel having a vertical structure like that of Patent Document 1, the entire control panel from top to bottom may not fit within the range between the height of the top floor and the height of the elevator shaft ceiling (hereinafter referred to as overhead dimension: OH dimension).

[0011] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0012] An outline of the overall configuration of an elevator system 100 will be described with reference to Figures 1 and 2. Figure 1 is a vertical cross-sectional view showing the configuration of an elevator system 100 according to an embodiment of the present invention. Figure 2 is a horizontal cross-sectional view showing the configuration of an elevator system 100 according to an embodiment of the present invention.

[0013] As shown in FIG. 1, the elevator device 100 includes a car 104 and a counterweight 105 that rise and fall within 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 rise and fall of the car 104 and the counterweight 105, a control panel 1 that controls the elevator device 100, and a governor 111 for detecting the rise and fall speed of the car 104.

[0014] The car 104 and counterweight 105 are provided inside a hoistway 101 provided 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 buffer 106 is provided on the bottom of the hoistway 101, below the car 104 and counterweight 105.

[0015] 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.

[0016] The guide rail 109 is fixed to an inner wall (hoistway wall) 101 a of the hoistway 101 by a rail bracket 110 .

[0017] 2, the car 104 is provided with a car door 104a on the side facing the elevator hall 112, and a space is provided between the side surface other than the side surface on which the car door 104a is provided and the elevator shaft wall 101a in which devices such as the hoist 102 and the control panel 1 are disposed. The car 104 is provided with a posidetector 104b for detecting the position of the car 104, which protrudes from one side surface position of the car 104 toward the elevator shaft wall 101a.

[0018] The elevator device 100 of this embodiment is of the traction type, in which the hoist 102 frictionally drives the main rope 107 to raise and lower the car 104 up and down along the car guide rail 109A, and raise and lower the counterweight 105 up and down along the counterweight guide rail 109B.

[0019] 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.

[0020] The pair of car guide rails 109A are arranged separately on the hoistway wall 101a on both the left and right sides of the passenger car 104 when viewed from the elevator hall 112 side. 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 provided for the car guide rail 109A and dedicated to the car guide rail.

[0021] The pair of counterweight guide rails 109B are disposed in the space in which the counterweight 105 is disposed. That is, the pair of counterweight guide rails 109B are disposed in the same space on either the left or right side of the car 104 as 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 of the car 104, and the counterweight rail bracket 110B is fixed to the hoistway wall 101a facing the back of the car 104.

[0022] Hereinafter, in the case where there is no need to distinguish between "for car" and "for counterweight" in the car guide rail 109A and the counterweight guide rail 109B, "for car" and "for counterweight" will be omitted and they will be simply referred to as the guide rail 109. Also, in the case where there is no need to distinguish between "for common use", "for counterweight" and "for car" in the car rail bracket 110A, the counterweight rail bracket 110B and the common rail bracket 110C, they will be simply referred to as the rail bracket 110, omitting "for common use", "for counterweight" and "for car".

[0023] The hoisting machine 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 hoisting machine 102. The hoisting machine 102 is fixed to the hoistway wall 101a by the machine beam 102a described in FIG. 1, and the machine beam 102a is installed between the car guide rail 109A and the counterweight guide rail 109B, so that the hoisting machine 102 is fixed to the hoistway wall 101a via the car guide rail 109A and the counterweight guide rail 109B.

[0024] 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 hoistway 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 hoistway 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.

[0025] 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 a counterweight guide rail 109B, and the control panel 2 is fixed to the hoistway wall 101a via the counterweight guide rail 109B.

[0026] The second control panel (option panel) 2 is a control panel that implements control components required as customer option 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.

[0027] The configuration of the control panel 1 will be described with reference to Fig. 3. Fig. 3 is an external view of the control panel 1 of the elevator device 100 according to one embodiment of the present invention.

[0028] The control panel 1 has a main circuit panel section 11, a power receiving panel section 12, a signal panel section 13, a regenerative resistor panel section 14, and a battery panel section 15.

[0029] The main circuit board section 11 is a control board section that implements main circuit elements, control boards, and the like for controlling the motor and brake of the hoisting machine 102. The main circuit board section 11 includes a power supply board section 16. The power supply board section 16 is a control board 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.

[0030] The power receiving panel section 12 is a control panel section which implements a terminal block for receiving the power source for the hoisting machine 102, a circuit breaker and an electromagnetic contactor for turning on / off the power source, a filter circuit for removing noise superimposed on the power line, and the like.

[0031] 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.

[0032] The regenerative resistance panel unit 14 is a control panel unit that has mounted thereon resistors for consuming, as thermal energy, the regenerative current that is generated when the elevator device 100 is in regenerative operation.

[0033] 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 a counterweight in the event of a breakdown in the elevator device 100, thereby performing a "brake release" to rescue passengers.

[0034] In the control panel 1, the main circuit board section 11 and the power receiving board section 12 are arranged side by side so as to be parallel to each other. 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: 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.

[0035] 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 the other control panel sections can be reduced.

[0036] In particular, in the control panel 1 of this embodiment, the regenerative resistor panel section 14 is disposed above the main circuit panel section 11, and the signal panel section 13 is disposed 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 disposed in a line (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 disposed in a line (series) in the vertical direction of the control panel 1. The power receiving panel section 12 is disposed so as to protrude horizontally (laterally) 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 disposed in series. As a result, a space is formed below the power receiving panel section 12.

[0037] By forming a space below the power receiving panel unit 12, this space can be utilized to connect wiring members to the power receiving panel unit 12 from below the power receiving panel unit 12, making it easy to route the wiring. For example, the power receiving panel unit 12 is connected to the lead-in wire 19 of the power source for the hoisting machine 102 from the space formed below the power receiving panel unit 12, making it easy to route the lead-in wire 19.

[0038] Conventionally, the functions of the power receiving unit 12 have sometimes been 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 into the power receiving unit 12. Also, the power supply board unit 16 is disposed in the main circuit board unit 11. It is preferable to dispose the power receiving board unit 12 below the main circuit board unit 11. In this case, the power supply board unit 16 may be disposed closer to the lower end of the main circuit board unit 11 than the upper end, but it is sufficient that it is disposed below the inspection height (1650 mm) described below.

[0039] Fixing portions 14a, 11a, 12a, 13a, and 15a that fix the control panel 1 to the control panel bracket 1a as shown in Fig. 5 are provided on the horizontal side edges of each control panel section, i.e., 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. The fixing portions 14a, 11a, 12a, 13a, and 15a are configured as flange portions (control panel flange portions) that protrude laterally from the control panel 1.

[0040] The fixing 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. The fixing part 11a is provided on one side edge of the main circuit panel section 11 opposite the power receiving panel section 12. The fixing part 12a is provided on one side edge of the power receiving panel section 12 opposite the main circuit panel section 11.

[0041] 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.

[0042] The configurations of the main circuit board section 11 and the power receiving board section 12 will be described with reference to Fig. 4. Fig. 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 Fig. 3.

[0043] 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 covered with a single lid 17b. That is, 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.

[0044] 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 the control board sections 14a, 11a, 12a, 13a, and 15a are configured to be connectable to each other.

[0045] The mounting structure (fixing structure) of the control panel 1 will be described with reference to Fig. 5. Fig. 5 is a diagram showing the mounting structure of the control panel 1 shown in Fig. 3.

[0046] In this embodiment, the control panel 1 is fixed to the hoistway wall 101a by a car guide rail 109A which is fixed to the hoistway wall 101a by a car rail bracket 110A. For this purpose, 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.

[0047] A tail cord 108 from the car 104 is connected to the signal panel unit 13 as shown in Fig. 5. The tail cord 108 is supported near one end connected to the signal panel unit 13 by a tail cord support 108b fixed to a tail cord support bracket 108a. The tail cord support bracket 108a is fixed to a car guide rail 109A, and the tail cord support 108b is fixed to the hoistway wall 101a via the tail cord support bracket 108a and the car guide rail 109A.

[0048] 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 can be arranged using this space, so that it does not protrude significantly beyond the side of the control panel 1.

[0049] In this embodiment, the control panel 1 is placed near the top floor. FLt shown 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 hoistway 101, i.e., the height dimension of the hoistway space formed above the floor height position FLt of the top floor.

[0050] The layout of the control panel 1 will be described with reference to Fig. 6. Fig. 6 is a diagram for comparison with a comparative example, for explaining features relating to the layout of the control panel 1 shown in Fig. 3.

[0051] 6(a) and (b) show a control panel 1' in a comparative example. In the control panel 1' in the comparative example, 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 in this order from the top. 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 arranged distributed between the main circuit panel section 11' and the signal panel section 13' in the control panel 1'.

[0052] As shown in Fig. 6(a), if the control panel 1' of the comparative example is to be disposed below the upper end portion 101b of the elevator shaft 101, the main circuit board section 11' will be located below the floor height position FLt of the top floor. The parts of the control panel 1' to be inspected during statutorily prescribed periodic inspections (statutory inspections) such as insulation tests (hereinafter referred to as inspection parts) are the signal board section 13' and the main circuit board section 11', which are the parts indicated by the dashed line T. In this case, the main circuit board section 11' of the inspection part T is located below FLt.

[0053] In 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 rides on 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.

[0054] In this case, if the control panel 1' and FLt are in the positional relationship shown in Fig. 6(a), the worker will not be able to inspect the main circuit board section 11' from above the car 104b. Therefore, in Fig. 6(a), the worker will need to move the car 104 to a height position where the inspection area of ​​the main circuit board section 11' can be inspected, which makes the inspection work more complicated and increases the inspection time.

[0055] Thus, Fig. 6(b) shows an example in which the main circuit panel section 11' is disposed above FLt so that the main circuit panel section 11' 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 located above the upper end section 101b of the hoistway 101, and the control panel 1' cannot be accommodated 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 disposed at a position that exceeds the height (set to 1650 mm in this embodiment) that allows inspection from above the car 104b without using a stepladder or the like.

[0056] 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 Figure 3, the inspection area T is located above the car top 104b and within the height range that can be inspected, as shown in Figure 6 (c).

[0057] As described 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 parts in the signal board unit 13 are concentrated in the upper part of the signal board unit 13. In Fig. 6(c), the lower part of the signal board unit 13 is located below FLt, but this lower part is not subject to regular inspection, and does not affect the workability during regular inspection.

[0058] 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 below the main circuit board section 11, so that the inspection parts within the main circuit board section 11 are concentrated at the lower part 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 periodic inspection and does not affect the workability during periodic inspection.

[0059] As described above, in this embodiment, the inspection parts of the main circuit board unit 11, the power receiving board unit 12, and the signal board unit 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.

[0060] The arrangement of devices 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 devices 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 in the control panel 1.

[0061] Fig. 7(c) shows an example in which the control panel 1, the hoist 102, and the counterweight 105 are arranged in the same manner as in Fig. 2. The car guide rail 109A and the counterweight guide rail 109B are also arranged in the same manner as in Fig. 2. Note that Fig. 7 illustrates the rope end 107a on the car 104 side. The rope end 107a is arranged on the hoistway wall side opposite the hoistway wall on the side where the hoist 102 and the counterweight 105 are arranged, sandwiching the car 104.

[0062] FIG. 7(a) shows an example in which the arrangement of the control panel 1 is changed from that of FIG. 2 (FIG. 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, the control panel 1 is preferably arranged close to the wall surface of the elevator shaft 101 on the side where the hoisting machine 102 is arranged, that is, the wall surface on the left side as viewed from the elevator hall 112 side. This allows the wiring between the control panel 1 and the hoisting machine 102 to be shortened. Although not shown in FIG. 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 manner as in FIG. 7(c).

[0063] FIG. 7(b) shows an example in which the arrangement of the hoist 102 and the counterweight 105 is changed from that in FIG. 7(a). In this case, the hoist 102 and the 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 closer to the right-hand hoistway wall as viewed from the elevator hall 112 side. The arrangement of the main circuit board unit 11 and the power receiving unit 12 is also swapped from that in FIG. 7(a). Although not shown in FIG. 7(b), the arrangement of the common rail bracket 110C is also changed with the change in the arrangement of the counterweight guide rail 109B, and is arranged on the same side as the counterweight 105. In this case, similarly to the case of Fig. 7(a), the control panel bracket 1a for fixing the control panel 1 may be fixed to the counterweight guide rail 109B arranged near the control panel 1. The rope end 107a is arranged on the side of the hoistway wall facing the hoistway wall on the side where the hoisting machine 102 and the counterweight 105 are arranged, and is arranged on the opposite side to the side where it is arranged in Fig. 7(a).

[0064] FIG. 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 FIG. 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 FIG. 7(d), the common 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 FIG. 7(c), but is fixed to the car guide rail 109A on a different side (opposite side) from that in FIG. 7(c).

[0065] As shown in Fig. 7, the arrangement of the control panel 1, the hoist 102, and the counterweight 105 can be changed from that of Fig. 2. By changing the arrangement of the control panel 1, the hoist 102, and the counterweight 105, the arrangements of the car guide rail 109A and the counterweight guide rail 109B, the car rail bracket 110A, the counterweight rail bracket 110B, and the shared rail bracket 110C are also changed as appropriate. In addition, by changing the arrangement of the control panel 1, the car guide rail 109A, and the counterweight guide rail 109B, the guide rail 109 that fixes the control panel bracket 1a is also changed as appropriate.

[0066] In addition, although Figure 7 illustrates the arrangement of the main circuit board section 11 and the receiving board section 12, the arrangement of the main circuit board section 11 and the receiving board section 12 is not limited to the arrangement in Figure 7, and the positions of the main circuit board section 11 and the receiving board section 12 in Figure 7 may be interchanged.

[0067] In addition, in the configurations of Figures 7 (c) and (d), since equipment such as the control panel 1 is not arranged on the back side of the car 104, a car door 104a can be provided on the back side of the car 104 as well.

[0068] The installation of the control panel 1 in the elevator device 100 will be described with reference to Fig. 8. Fig. 8 is a diagram showing the state of installation of the control panel 1 shown in Fig. 3.

[0069] When the control panel 1 is installed in the hoistway 101, the regenerative resistance panel section 14, the main circuit panel section 11, and the power receiving panel section 12 are integrated and lifted by the lifting hook 21 to perform the work. The regenerative resistance panel section 14, the main circuit panel section 11, and the power receiving panel section 12 can be integrated by connecting them to each other by the connecting section 17c described in FIG. 4. This allows the regenerative resistance panel section 14 to be lifted together with the main circuit panel section 11 and the power receiving panel section 12 by hooking a wire rope to the main circuit panel section 11. Even if a sufficient gap cannot be secured above the regenerative resistance panel section 14, the regenerative resistance panel section 14 can be lifted together with the main circuit panel section 11 and the power receiving panel section 12 by securing a hanging allowance.

[0070] The lifted regenerative resistor panel section 14, main circuit panel section 11, and power receiving panel section 12 are attached to the control panel bracket 1a. In this case, it is advisable to attach shackles to the upper portions of both side edges (control panel flange sections) 11a, 12a of the main circuit panel section 11 and the power receiving panel section 12 to prevent them from falling over, and to loop the wire rope around the shackles.

[0071] In Fig. 8, the signal panel section 13 and the battery panel section 15 may be attached to the control panel bracket 1a separately from the main circuit panel section 11 and the power receiving panel section 12, or may be attached to the control panel bracket 1a together with the main circuit panel section 11 and the power receiving panel section 12. That is, the signal panel section 13 and the battery panel section 15 may be attached to the control panel bracket 1a separately, the signal panel section 13 and the battery panel section 15 may be attached to the control panel bracket 1a separately from the main circuit panel section 11 and the power receiving panel section 12, or the signal panel section 13, the battery panel section 15, the main circuit panel section 11 and the power receiving panel section 12 may be attached to the control panel bracket 1a together. Note that even in this case, the regenerative resistor panel section 14 is still attached to the control panel bracket 1a together with the main circuit panel section 11 and the power receiving panel section 12.

[0072] A periodic inspection of the control panel 1 will be described with reference to Fig. 9. Fig. 9 is a diagram showing a state of a periodic inspection of the control panel 1 shown in Fig. 3.

[0073] Driving devices such as the hoist 102 and the control panel 1 are concentrated and arranged at the top of the elevator shaft 1, so there is a lot of competition for space to arrange each piece of equipment, and the mounting height of each piece of equipment is also limited. In this situation, to improve maintainability, the inspection points for periodic inspections of the control panel 1 are arranged above FLt and up to an inspectable height (1650 mm) with the car top 101b of the car 104 positioned at FLt.

[0074] Furthermore, in this embodiment, the governor 111 and the inspection portion of the control panel 1 are arranged in a range above FLt and up to an inspectable height (1650 mm). That is, the elevator system 100 of this embodiment is equipped with a governor 111 for detecting the ascent and descent speed of the car 104, and the governor 111 is arranged below the upper ends of the main circuit board unit 11 and the power receiving board unit 12. This makes it possible to carry out maintenance work and inspection work on the governor 111 and the control panel 1 in parallel.

[0075] Furthermore, when performing maintenance on the hoisting machine 102 from above the car 104b, it is necessary to shut off the power switch 102b of the hoisting machine 102. In this embodiment, by providing the power switch 102b on the power receiving panel unit 12, it is not necessary to provide a new power switch box on the hoisting machine 102. Furthermore, the hoisting machine 102 is often disposed near the upper end 101b at the top of the hoistway 101, and is disposed at a position higher than the height at which it can be inspected (1650 mm). Even in such a case, by providing the power switch 102b on the power receiving panel unit 12, it is possible to place the power switch 102b within the range of the height at which it can be inspected (1650 mm), and it becomes easy to shut off the power switch 102b of the hoisting machine 102.

[0076] In this embodiment, the embodiment in which the driving devices such as the hoist 102 and the control panel 1 are arranged 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 arranged at a location other than the top of the elevator shaft 1. For example, when the control panel 1 is arranged at the height of the second floor of the elevator shaft 101, FLt is 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 lowered to FLt. Even in such a case, by adopting the configuration of the control panel 1 of this embodiment, the inspection part of the control panel 1 can be arranged within a range of a height (1650 mm) that can be inspected from the car top 104b of the car 104 lowered to the lowest part.

[0077] The present invention is not limited to the above-mentioned embodiment, and various modifications are included. For example, the above-mentioned embodiment is a detailed explanation of the present invention in an easy-to-understand manner, and is not necessarily limited to the embodiment having all the configurations described. It is also possible to replace a part of the configuration of one embodiment with the configuration of another embodiment, and it is also possible to add another embodiment to the configuration of one embodiment. It is also possible to add, delete, or replace a part of the configuration of each embodiment with another configuration. [Explanation of symbols]
