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

[0004] The main components of an elevator system are the control panel and the governor, and inspection of the control panel and the governor are required during maintenance and inspection. When an operator climbs onto the roof of the car (hereafter referred to as the car top) to perform inspection work, there is a limit to the height range at which the inspection work can be performed without using a stepladder or the like. If the control panel and the governor are located apart in height, it becomes necessary to change the height position of the car top, which serves as the operator's foothold, to match the height positions of the control panel and the governor. In addition, it is necessary to take measures to stop the car so that it does not move during inspection work, and this means that the stopping measures and their release must be repeated every time the height position of the car top is changed, which significantly reduces the efficiency of the inspection work.

[0005] An object of the present invention is to enable inspection work on a control panel and a governor to be performed from above the car without changing the height position of the car. [Means for solving the problem]

[0006] In order to solve the above problems, the elevator device of the present invention comprises: An elevator system comprising a car, a control panel and a governor disposed in a hoistway, and inspection work for the control panel and the governor is performed on the car, The inspection work area of ​​the control panel and the inspection work area of ​​the governor are positioned at a height where the inspection work can be performed without changing the height position of the car.

[0007] In order to solve the above problems, a method for inspecting an elevator apparatus according to the present invention includes: 1. An inspection method for an elevator system comprising a car, a control panel and a governor disposed in a hoistway, the inspection work for the control panel and the governor being performed on the car, comprising: The inspection work area of ​​the control panel and the inspection work area of ​​the governor are disposed at height positions where the inspection work can be performed without changing the height direction position of the car, The inspection work includes an insulation test of the control panel, a tripping test of the governor, and an emergency stop test, During the inspection work, the elevator car is not moved in the height direction, and the inspection work is performed by positioning the top of the car at the floor where the inspection work is to be performed. Effect of the Invention

[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] In Fig. 1, the size of the elevator shaft HW and the orientation of each device arranged in the elevator shaft HW are depicted in a different form from the actual one in order to explain the configuration of the elevator device 100. Also, in Fig. 1, the car 104 is shown stopped at a landing 112 on the top floor, and the handrail 104d provided on the car (ceiling) 104c is in a folded state (stored state).

[0014] As shown in FIG. 1, the elevator device 100 includes a car 104 and a counterweight 105 that rise and fall within a hoistway HW, 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 HW and guides the rise and fall of the car 104 and the counterweight 105, a control panel 101 that controls the elevator device 100, and a governor 111 for detecting the rise and fall speed of the car 104.

[0015] The car 104 and counterweight 105 are provided inside a hoistway HW provided in a building, and are suspended in a bucket-like manner by a main rope 107. One end of the main rope 107 is supported on the ceiling of the hoistway HW, hung around a pulley 104b provided on the underside of the car 104, and wound around a sheave of the hoisting machine 102. The other end of the main rope 107 wound around the sheave of the hoisting machine 102 is supported on the ceiling of the hoistway HW via a pulley of the counterweight 105.

[0016] The car 104 is electrically connected to the control panel 101 by a tail cord (not shown), receives power via the tail cord, and exchanges control signals and various other signals with the control panel 101. A buffer 106 is disposed on the bottom of the elevator shaft HW below the car 104 and counterweight 105.

[0017] The hoisting machine 102 is supported by a machine beam 102a and is disposed at the top of the hoistway HW. The control panel 101 is disposed near the hoisting machine 102. That is, the control panel 101 is also disposed at the top of the hoistway HW. The configuration of the control panel 101 will be described in detail later.

[0018] The guide rail 109 is fixed to an inner wall (hoistway wall) HW1 of the hoistway HW by a rail bracket (not shown).

[0019] 2 illustrates the elevator shaft HW as viewed from above the car 104, depicting an upper portion 104c of the car 104. As shown in FIG. 2, the car 104 is provided with a car door 104a on the side facing the elevator hall 112, and an entrance door 112a facing the car door 104a is provided on the elevator hall 112 side. A space is provided between the elevator shaft wall HW1 and the other sides of the car 104 except for the side on which the car door 104a is provided, in which equipment (equipment in the elevator shaft) such as the hoist 102, the governor 111, and the control panel 101 are disposed.

[0020] 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.

[0021] The guide rails 109 are erected in the vertical direction (height direction) along the elevator shaft wall HW1. As the guide rails 109 described in Fig. 1, a car guide rail 109A and a counterweight guide rail 109B are provided. The car guide rail 109A is a guide rail for the passenger car 104, and is composed of a pair of guide rails. The counterweight guide rail 109B is a guide rail for the counterweight 105, and is composed of a pair of guide rails.

[0022] The pair of car guide rails 109A are arranged separately on the hoistway wall HW1 on 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 HW1 by a shared rail bracket (not shown), and the other is fixed to the hoistway wall HW1 by a car rail bracket (not shown). The shared rail bracket is a rail bracket shared between the car guide rail 109A and the counterweight guide rail 109B. The car rail bracket is a rail bracket provided for the car guide rail 109A and dedicated to the car guide rail.

[0023] The pair of counterweight guide rails 109B are disposed in the space in the elevator shaft HW where 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 elevator shaft wall HW1 by a common rail bracket, and the other is fixed to the elevator shaft wall HW1 by a counterweight rail bracket (not shown). In this embodiment, the common rail bracket is fixed to the elevator shaft wall HW1 facing the left side surface (left side surface) of the car 104 as viewed from the front, and the counterweight rail bracket is fixed to the elevator shaft wall HW1 facing the back surface of the car 104.

[0024] Hereinafter, when there is no need to distinguish between the car guide rail 109A and the counterweight guide rail 109B, the terms "car" and "counterweight" will be omitted and they will simply be referred to as guide rail 109.

[0025] 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 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 HW1 via the car guide rail 109A and the counterweight guide rail 109B.

[0026] The control panel 101 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 101 is fixed to the hoistway wall HW1 by a control panel bracket (not shown). In this case, the control panel bracket is fixed to the car guide rail 109A, and the control panel 101 is fixed to the hoistway wall 101a via the car guide rail 109A.

[0027] The main devices of the elevator system 100, including the control panel 101, and their inspection work will be described with reference to Fig. 3. Fig. 3 is a schematic diagram showing the main devices of the elevator system 100 according to one embodiment of the present invention and the work environment during the inspection work.

[0028] The elevator system 100 of this embodiment is called a machine room-less elevator system, and the main equipment such as the hoist 102, the control panel 101, and the governor 111 are disposed at the top of the hoistway HW. When inspecting the main equipment, an operator OP gets into the car upper section 104c of the car 104 to perform the inspection work. During the inspection work, the car upper section 104c is positioned at a height position FLt of the landing 112 on the top floor so that the operator OP can get into the car upper section 104c. FIG. 3 shows a state in which the car upper section 104c is positioned at a height position FLt of the landing 112 on the top floor and the operator OP gets into the car upper section 104c. The operator OP who gets into the car upper section 104c unfolds the handrail 104d that was stored in order to prevent himself from falling from the car upper section 104c. The unfolded handrail 104d extends horizontally and has cross bars (upper cross bar 104d1, middle cross bar 104d2) arranged side by side in the vertical direction.

[0029] Here, a description will be given of the control panel 101. The control panel 101 has a main circuit panel section 101a, a power receiving panel section 101b, a signal panel section 101c, a regenerative resistor panel section 101d, and a battery panel section 101e.

[0030] The main circuit board unit 101a is a control board unit that mounts main circuit elements, a control board, and the like for controlling the motor and brake of the hoisting machine 102. The main circuit board unit 101a mounts a control power supply 101g for performing operation control of the elevator device 100, including the speed and position of the car 104.

[0031] The power receiving panel section 101b 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.

[0032] The signal panel unit 101c is a control panel unit on which a control board and the like for controlling the operation of the elevator device 100, including the speed and position of the car 104, are mounted.

[0033] The regenerative resistance panel unit 101d is a control panel unit that has a resistor mounted thereon for consuming, as thermal energy, a regenerative current that is generated when the elevator device 100 performs a regenerative operation.

[0034] The battery panel unit 101e 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.

[0035] In the control panel 101, a main circuit board section 101a and a power receiving board section 101b are arranged side by side. A regenerative resistor board section 101d is arranged above the main circuit board section 101a and the power receiving board section 101b, and a signal board section 13 is arranged below the main circuit board section 101a and the power receiving board section 101b. A battery board section 101e is arranged below the signal board section 101c. That is, the control panel 101 has a regenerative resistor panel section 101d, a main circuit panel section 101a, a power receiving panel section 101b, a signal panel section 101c, and a battery panel section 101e, with the main circuit panel section 101a and the power receiving panel section 101b being arranged in parallel horizontally, and the regenerative resistor panel section 14, the main circuit panel section 11 and the power receiving panel section 12, the signal panel section 13, and the battery panel section 15 being arranged from top to bottom in the following order: regenerative resistor panel section 14, main circuit panel section 11 and the power receiving panel section 12, the signal panel section 13, and the battery panel section 15.

[0036] The regenerative resistor panel section 101d is a control panel section that is prone to generating heat, and by placing it at the top among the main circuit panel section 101a, the power receiving panel section 101b, the signal panel section 101c, the regenerative resistor panel section 101d, and the battery panel section 101e, the thermal impact on the other control panel sections can be reduced.

[0037] In particular, in the control panel 101 of this embodiment, the regenerative resistor panel section 101d is disposed above the main circuit panel section 101a, and the signal panel section 101c is disposed below the main circuit panel section 101a. That is, the regenerative resistor panel section 101d, the main circuit panel section 101a, the signal panel section 101c, and the battery panel section 101e are disposed in a line (series) from the top to the bottom of the control panel 101 in this order. In other words, the regenerative resistor panel section 101d, the main circuit panel section 101a, the signal panel section 101c, and the battery panel section 101e are disposed in a line (series) in the vertical direction of the control panel 101. The power receiving panel section 101b is disposed so as to protrude horizontally (laterally) from the row of the regenerative resistor panel section 101d, the main circuit panel section 101a, the signal panel section 101c, and the battery panel section 101e disposed in series. For this reason, a space is formed below the power receiving panel section 101b.

[0038] By forming a space below the power receiving panel unit 101b, electrical wiring can be easily arranged by connecting electrical wiring to the power receiving panel unit 101b from below the power receiving panel unit 101b using this space. For example, the power receiving panel unit 101b can easily arrange the lead-in wire by connecting the lead-in wire (not shown) of the power source of the hoisting machine 102 from the space formed below the power receiving panel unit 101b.

[0039] Conventionally, the functions of the power receiving unit 101b have sometimes been distributed between the main circuit board unit 101a and the signal board unit 101c. In contrast to this, in this embodiment, the functions of the power receiving unit are consolidated into the power receiving unit 101b. Also, a control power supply 101g for controlling the operation of the elevator device 100 is disposed in the main circuit board unit 101a. In this case, the control power supply 101g may be disposed closer to the lower end than the upper end of the main circuit board unit 101a, but it is sufficient that it is disposed below an inspection height (e.g., 1650 mm) described below.

[0040] Since the main devices such as the control panel 101, the hoist 102, and the governor 111 are concentrated and arranged at the top of the elevator shaft HW, there is a lot of competition for the placement of each device, and the mounting height of each device is also limited. In this situation, in order to improve maintainability, the inspection work site 101f during inspection such as periodic inspection of the control panel 101 is arranged within a range (e.g., 0 to 1650 mm) up to a height (e.g., 1650 mm) at which an operator OP can inspect without using a stepladder, etc., with the car top 101c of the elevator car 104 positioned at FLt as the reference (0 mm). This allows the operator OP to perform the necessary inspection work on the control panel 101 from the car top 101c with the car top 101c of the elevator car 104 positioned at FLt.

[0041] Furthermore, in this embodiment, the inspection work portion 111d of the speed governor 111 is arranged within a range (e.g., 0 to 1650 mm) up to a height (e.g., 1650 mm) at which an operator OP can inspect the car without using a stepladder or the like, with the car top 104c positioned at FLt being set as the reference (0 mm). The elevator device 100 of this embodiment includes a speed governor 111 for detecting the ascending and descending speed of the car 104. The speed governor 111 is arranged below the upper ends of the main circuit board section 101a and the power receiving board section 101b. This makes it possible to carry out inspection work on the speed governor 111 and the control board 101 in parallel.

[0042] The inspection work areas 101f and 111d are not limited to areas where inspection is performed, but include areas where work associated with the inspection is performed.

[0043] In this embodiment, the main devices such as the control panel 101, the hoisting machine 102, and the governor 111 are arranged at the top of the hoistway HW. However, the configuration and the effects of the above embodiment can be utilized for the main devices such as the control panel 101, the hoisting machine 102, and the governor 111 arranged at a location other than the top of the hoistway HW. For example, when the control panel 101 is arranged at the height of the second floor (in this case, the second floor is not the top floor) of the hoistway HW, the FLt is set at the height of the landing floor of the second floor, and the car top 104c is positioned at the height of the landing floor of the second floor to perform the inspection work. However, when the hoisting machine 102 is arranged at the top of the hoistway HW, it is preferable to arrange the main devices such as the control panel 101 and the governor 111 at the top of the hoistway HW close to the hoisting machine 102. This improves the efficiency of the inspection work.

[0044] In this way, FLt represents the landing 112 of the floor where the inspection work of the control panel 101 and the governor 111 is performed, or its height position.

[0045] In this embodiment, the height HOP of the worker OP is set to 1700 mm, and the inspection height H1 is set to 1650 mm.

[0046] A handrail 104d is deployed above the car 104c during inspection work. In this embodiment, the handrail 104d has two horizontal bars 104d1 and 104d2. The height H2 of the upper end of the upper bar 104d1 is 1100 mm. The height H3 of the lower end of the middle bar 104d2 is set to 500 mm or less (500 mm in this embodiment). When the vertical width dimension W1 of the two horizontal bars 104d1 and 104d2 is 50 mm, the interval G1 between the lower end of the upper bar 104d1 and the upper end of the middle bar 104d2 is 550 to 1050 mm. In addition, the area between the upper end H2 of the upper bar 104d1 and the inspection height H1 (1100 to 1650 mm) is the non-interference range of the handrail 104d. In addition, non-interference ranges of the horizontal rails 104d1 and 104d2 are provided between FLt and the height H3 of the lower end of the middle rail 104d2, and between the lower end of the upper rail 104d1 and the upper end of the middle rail 104d2. Note that the specific values ​​of H1 to H3, G1, and W1 are merely examples set in this embodiment.

[0047] The governor 111 is a device that detects the ascending and descending speed of the car 104, and has a main body (governor sheave) 111a, an upper diverting pulley 111b arranged above the main body 111a, a lower diverting pulley 111c arranged below the main body 111a, and a governor rope 111e wound around the main body 111a, the upper diverting pulley 111b, and the lower diverting pulley 111c.

[0048] Among the inspection tasks performed during regular inspections, there are three tasks that take a lot of time. The first is an insulation test of the control panel 101, the second is a tripping test of the governor 111, and the third is an emergency stop test. The tripping test of the governor 111 is a test to check whether the governor 111 operates normally, and it is necessary to put the main body (governor sheave) 111a in a state in which it can rotate freely. For this purpose, it is necessary to remove the governor rope 111e from the main body 111a and release the load of the governor rope 111e applied to the main body 111a (hereinafter referred to as the "pulled-up state"). At that time, it is necessary to lift up the lower diverting pulley 111c.

[0049] In order to access the lower diverting pulley 111c, it is preferable to arrange the main body 111a, the upper diverting pulley 111b and the lower diverting pulley 111c so that the inspection work part 111d of the speed governor 111 does not interfere with the handrail 104d. For this reason, it is preferable to arrange the main body 111a above the horizontal rails 104d1 and 104d2. It is also preferable to arrange the lower diverting pulley 11c below the upper rail 104d1 and above the middle rail 104d2. Alternatively, it is preferable to arrange the lower diverting pulley 111c above the car top 104c and below the middle rail 104d2.

[0050] Furthermore, in the tripping test and emergency stop test of the governor 111, it is necessary to attach tools required for the test to the main body 111a of the governor 111. For example, a drive device that rotates the main body 111a, an encoder that detects the number of rotations, etc. In order not to interfere with this installation work, it is preferable to place the main body 111a above the handrail 104d.

[0051] Furthermore, for safety reasons, in the emergency stop test, the worker OP needs to get off from the car top 104c to the landing 112 to perform the test. For this reason, in order to reduce the travel time between the car top 104c and the landing 112, it is preferable to place the speed governor 111 on the side closer to the landing 112. Also, by placing the speed governor 111 on the side closer to the landing 112, the movement line of the worker OP is simplified, and work efficiency can be improved.

[0052] In this case, it is preferable that the speed governor 111 is disposed closer to the car door 104a than to the rear side surface (the side surface opposite to the car door 104a side) 104e of the car 104 as viewed from the landing 112 side. If possible, it is preferable that the main body 111a, upper diverting pulley 111b, lower diverting pulley 111c, and speed governor rope 111e of the speed governor 111 are disposed within a range of 1 m on the rear side from the car door 104a.

[0053] An inspection method for the elevator apparatus 100 according to the present invention will be described with reference to Fig. 4. Fig. 4 is a flowchart of the inspection method for the elevator apparatus 100 according to the present invention.

[0054] Note that Figure 4 shows an inspection method in which the control panel 101 and the governor 111 are located at a height position where inspection work can be performed from the car top 104c located at the same FLt, and the hoist 102 is located at a height position where inspection work cannot be performed from the car top 104c located at the same FLt.

[0055] In step S101, the elevator moves to the top floor landing 112. In step S102, the elevator car 104 moves to FLt. In step S103, the handrail 104d is assembled. In step S104, the worker OP gets on top of the elevator car 104c. In step S105, the main power supply (control power supply) 101g of the control panel 101 is shut off (first step). Then, steps S106, S107 and steps S108, S109 are executed in parallel. In this case, executing steps S106, S107 and steps S108, S109 in parallel means that at least some of the work in steps S106 and S107 and at least some of the work in steps S108 and S109 are executed in parallel at the same time. Of course, this also includes the case where the entire work of steps S106 and S107 and the entire work of steps S108 and S109 are performed in parallel at the same time.

[0056] In step S106, the process waits for the capacitor to discharge (about 10 minutes) (second step). In step S107, an insulation test (insulation measurement) is performed (third step). During the insulation test, it is necessary to shut off the main power supply (control power supply) 101g of the control panel 101 and wait until the capacitor has completely discharged. The car 104 cannot move until the main power supply 101g is turned back on in step S110.

[0057] Meanwhile, in step S108, tools (driver, encoder, etc.) for the governor tripping test are attached (fourth step). In step S109, a governor tripping test (governor tripping measurement) is performed (fifth step), and recovery work (removal of the tools, etc.) is performed.

[0058] By executing steps S106 and S107 and steps S108 and S109 in parallel, the work efficiency is improved. In particular, since the governor tripping test tool can be installed during the waiting time for the capacitor to discharge (about 10 minutes), it is possible to eliminate wasted time and shorten the work time.

[0059] In step S110, the main power supply 101g of the control panel 101 is turned on. In step S111, the stop switch of the car 104 is turned on to prevent the car 104 from ascending or descending. In step 112, the speed governor 111 is fixed in the raised state. In step 113, the worker OP descends from the car top 104c to the landing 112. In step S114, an emergency stop test is performed. If it is confirmed that there is no abnormality in the emergency stop device 114, the emergency stop device 114 is reset, and in step S114-1, the worker OP boards the car top 104c. In step S115, the raised state of the speed governor 111 is released. In step S116, the stop switch of the car 104 is reset.

[0060] In step S117, the car 104 is moved to an inspection position for the hoist 102. In step S118, the stop switch of the car 104 is turned on. In step S119, the hoist 102 and the braking device are inspected. In step S120, the operator OP inspects the inside of the tower (various ropes, landing doors for each floor, etc.) while moving to the lowest floor + 1 floor. In step S121, the operator OP stores the handrail 104d and descends from the car top 104c. In step S122, the operator OP moves to the lowest floor and enters the pit. In step S123, it is confirmed that the emergency stop device 114 has returned to normal. In step S124, the equipment in the pit and the equipment under the car are inspected, and in step S125, the operator OP exits the pit.

[0061] In this embodiment, while performing inspection work including an insulation test of the control panel 101, a tripping test of the governor 111, and an emergency stop test, the inspection work is performed by positioning the car top 104c at a specified floor (height position) FLt without moving the car 104 in the lifting direction (up and down or height direction).

[0062] An inspection method for an elevator device in a comparative example with respect to the present invention will be described with reference to Fig. 5. Fig. 5 is a flowchart of an inspection method for an elevator device in a comparative example with respect to the present invention.

[0063] Note that Figure 5 shows an inspection method in the case where the control panel 101, the governor 111, and the hoist 102 are each located at a height where inspection work cannot be performed from above the car 104c, which is located at the same FLt.

[0064] In this comparative example, after the insulation test (insulation measurement) in step S107, the car-top 104c needs to be adjusted to the height position of the governor 111 for the governor tripping test S108. That is, in step S201, it is necessary to move the car 104 to the position of the governor 111. For this reason, after the governor tripping test S108 is performed, it is necessary to return the stop SW (S202) and move the car 104 to FLt (S203). Also, after the emergency stop test S114, it is necessary to move the car 104 to the position of the governor 111 again in order to adjust the car-top 104c to the height position of the governor 111 (S204). Then, after step S204, the stop SW is turned on in step S205.

[0065] Thus, in this comparative example, compared to the above-mentioned embodiment, not only cannot steps S106, S107 and steps S108, S109 be executed in parallel, but also there is an additional need to move the car 104 (S201, S203, S204) and to return and engage the stop SW (S202, S205) associated with the movement of the car 104 (S201, S203, S204).
