Description

Technical Field

[0001] The present invention relates to an elevator apparatus provided with an emergency stop device that operates electrically.

Background Art

[0002] An elevator apparatus is provided with a speed governor and an emergency stop device for constantly monitoring the ascending / descending speed of a car and emergency-stopping the car that has fallen into a predetermined overspeed state. Generally, the car and the speed governor are connected by a speed governor rope. When an overspeed state is detected, the speed governor brakes the speed governor rope, thereby pulling up the brake of the emergency stop device on the car side. As a result, the emergency stop device operates and the car is emergency-stopped.

[0003] In such an elevator apparatus, since a governor rope, which is a long object, is laid in the hoistway, it is difficult to save space and reduce costs. Further, when the governor rope swings, it is likely that the structure in the hoistway and the governor rope interfere with each other.

[0004] On the other hand, an emergency stop device that does not use a governor rope has been proposed.

[0005] As a prior art related to an emergency stop device that does not use a governor rope, the technique described in Patent Document 1 is known.

[0006] In this prior art, an operating mechanism for operating the emergency stop device is provided in the car. The operating mechanism includes an operating rod connected to the brake and an electromagnet unit that operates the operating rod. The operating rod includes a permanent magnet unit.

[0007] Normally, since the permanent magnet unit is attracted to the electromagnet unit, the brake is fixed to the car via the operating rod.

[0008] In an emergency, the current flowing through the electromagnet is controlled to generate a repulsive force on the electromagnet. As a result, the permanent magnet separates from the electromagnet and is attracted to the guide rail. This releases the brake from its attachment to the elevator car, and it is then fixed to the guide rail via the operating rod. At this time, since the elevator car continues to descend, the brake is raised relative to the elevator car. [Prior art documents] [Patent Documents]

[0009] [Patent Document 1] U.S. Patent Application Publication No. 2020 / 0048042 [Overview of the project] [Problems that the invention aims to solve]

[0010] In the conventional technology described above, magnetic foreign matter such as iron powder or other magnetic dust may adhere to the adsorption surface of the permanent magnet, potentially reducing the adsorption force between the permanent magnet and the guide rail in an emergency. Consequently, the reliability of the emergency stop device may be reduced.

[0011] Therefore, the present invention provides an elevator device that can improve the reliability of an emergency stop device operated by an operating mechanism equipped with a magnet. [Means for solving the problem]

[0012] To solve the above problems, the elevator system according to the present invention comprises an elevator car, an emergency stop device provided in the elevator car, and an emergency stop system having an operating mechanism for operating the emergency stop device, wherein the elevator car moves up and down while being guided by a guide rail, and the operating mechanism comprises an operating rod connected to a braker provided in the emergency stop device, and a magnetic part provided on the operating rod, wherein when the emergency stop device is operated, the operating mechanism attracts the magnetic part to the guide rail, Furthermore, it is equipped with one of the following means: The first method involves arranging the emergency stop device and the operating mechanism side by side in the vertical direction, with the operating mechanism located below the emergency stop device and having a permanent magnet section fixed to the upper part of the housing of the emergency stop device, the permanent magnet section being adjacent to the guide rail, and the magnetic poles of the permanent magnet section being exposed in the elevator shaft. The second method involves arranging the emergency stop device and the operating mechanism side by side in the vertical direction, with the operating mechanism located above the emergency stop device and having a permanent magnet section fixed to the upper part of the housing of the operating mechanism, the permanent magnet section being adjacent to the guide rail, and the magnetic poles of the permanent magnet section being exposed in the elevator shaft. A third method involves providing the permanent magnet portion on the outer surface of a cover member that covers the side of the operating mechanism, with the permanent magnet portion adjacent to the guide rail, and the magnetic pole portion of the permanent magnet portion exposed within the elevator shaft.

Advantages of the Invention

[0013] According to the present invention, since the permanent magnet portion adsorbs magnetic foreign substances, the reliability of the emergency stop device is improved.

[0014] Problems, configurations, and effects other than those described above will be clarified by the description of the following embodiments.

Modes for Carrying Out the Invention

[0016] Hereinafter, an elevator device which is an embodiment of the present invention will be described with reference to the drawings by way of examples. In each figure, components having the same reference numerals indicate the same components or components having similar functions.

[0017] Figure 1 is a schematic configuration diagram of an elevator device according to an embodiment of the present invention.

[0018] This elevator device has a hoisting machine installed at the upper part of the hoistway. One end of the main rope 2 wound around the traction sheave 1 and the direction-changing pulley 8 in the hoisting machine is connected to the car 3, and a counterweight 4 is connected to the other end of the main rope 2.

[0019] The car 3 is suspended in the hoistway by the main rope 2. When the hoisting machine is driven by an electric motor and the traction sheave 1 rotates, the main rope 2 is driven. As a result, the car 3 moves up and down in the hoistway along a pair of car guide rails 5A and 5B installed in the hoistway. Also, the counterweight 4 moves up and down in the hoistway in the opposite direction to the car 3 along a pair of counterweight guide rails 6A and 6B installed in the hoistway.

[0020] At the lower part of the car 3, in case of emergency, an emergency stop device 20 that sandwiches the car guide rails 5A and 5B by a brake (described later) to stop the movement of the car 3 and an operating mechanism 30 that operates the emergency stop device 20 are arranged. In this embodiment, the emergency stop device 20 is provided one on each of the left and right sides at the lower part of the car 3. Also, the operating mechanism 30 is provided below the emergency stop device 20 and one on each of the left and right sides at the lower part of the car 3.

[0021] As shown in the view taken in the direction of arrow A shown together in Figure 1, in the emergency stop system composed of the emergency stop device 20 and the operating mechanism 30, the emergency stop device 20 and the operating mechanism 30 are arranged side by side in the vertical direction. In this embodiment, the operating mechanism 30 is located below the emergency stop device 20. At the upper part of the emergency stop system, in this embodiment, at the upper part of the emergency stop device 20, a permanent magnet piece 51 is provided.

[0022] The magnetic pole surface of the permanent magnet piece 51 is exposed inside the elevator shaft. As a result, the permanent magnet piece 51 attracts magnetic foreign matter such as iron filings and other magnetic dust that comes relatively close to the upper part of the emergency stop device 20 inside the elevator shaft. This prevents magnetic foreign matter from entering the emergency stop device 20 and the operating mechanism 30.

[0023] Furthermore, as shown in the view from arrow A, the side of the operating mechanism 30 is covered by a cover member 40. This prevents foreign matter, including magnetic foreign matter, from entering the operating mechanism.

[0024] A speed detection device (not shown) is provided in the elevator car 3, which constantly detects the elevator car's speed within the hoistway. Therefore, the speed detection device can detect when the elevator car's speed exceeds a predetermined overspeed.

[0025] For example, the speed detection device includes an image sensor and detects the speed of the elevator car 3 based on image information of the surface condition of the elevator car guide rail 5A or 5B acquired by the image sensor. Alternatively, the speed detection device may calculate the speed of the elevator car 3 based on the output signal of a rotary encoder installed on the elevator car 3 that rotates with the movement of the elevator car 3.

[0026] The elevator system in this embodiment is equipped with a so-called ropeless governor system that does not use a governor rope. When the lifting speed of the elevator car 3 exceeds the rated speed and reaches a first overspeed (for example, a speed not exceeding 1.3 times the rated speed), the power supply to the hoisting machine's electric motor and the power supply to the control device that controls the electric motor are shut off. Furthermore, when the lifting speed of the elevator car 3 reaches a second overspeed (for example, a speed not exceeding 1.4 times the rated speed), the emergency stop device 20 installed in the elevator car 3 is activated, and the elevator car 3 is brought to an emergency stop.

[0027] In this embodiment, the ropeless governor system consists of the aforementioned speed detection device and a safety control device (not shown) that determines the overspeed state of the elevator car 3 based on the output signal of the speed detection device. The safety control device measures the speed of the elevator car 3 based on the output signal of the speed detection device, and when it determines that the measured speed has reached a first overspeed, it outputs a command signal to shut off the power supply to the electric motor of the hoisting machine and the power supply to the control device that controls this electric motor. Furthermore, when the safety control device determines that the measured speed has reached a second overspeed, it outputs a command signal to activate the operating mechanism 30.

[0028] Figure 2 is a diagram showing the mechanical configuration of the emergency stop device 20 and the operating mechanism 30 in this embodiment. Figure 2 corresponds to a partially enlarged view of Figure 1 (viewed from arrow A). Note that the cover member 40 shown in Figure 1 is not shown in Figure 2 (the same applies to Figures 5 and 7).

[0029] In Figure 2, the emergency stop device 20 is in a non-operating state. In other words, the elevator car 3 is in a normal operating state.

[0030] In the emergency stop device 20, the pair of wedge-shaped brakes 22 are moved by the operating mechanism 30 within the housing 21 from the non-braking position shown in Figure 2 to a braking position above the non-braking position during an emergency. In this braking position, the brake element 22 is clamped by a pair of guide members 23 fixed inside the housing 21.

[0031] The operating mechanism 30 includes an operating rod 34 for operating a pair of brakes 22 and an electromagnet unit 33 for actinguating the operating rod 34. One end of the operating rod 34 is rotatably connected to a permanent magnet unit 32. The other end of the operating rod 34 is rotatably connected to one of the pair of brakes 22. The electromagnet unit 33 is fixed inside the housing 31.

[0032] The permanent magnet section 32, the electromagnet section 33, and the operating rod 34 are located within the housing 31 on one of the left or right sides of the elevator car guide rail 5A. The permanent magnet section 32 is located between the electromagnet section 33 and the elevator car guide rail 5A. The braker 22, to which the operating rod 34 is connected, is located together with the permanent magnet section 32, the electromagnet section 33, and the operating rod 34 on one of the left or right sides of the elevator car guide rail 5A.

[0033] A pair of brakes 22 are connected to each other via a connecting member 36. The connecting member 36 is connected to each brake 22 by a connecting pin. As a result, the pair of brakes 22 operate as a single unit. An operating rod 34 is rotatably connected to one of the pair of brakes 22 via a connecting pin. The operating rod 34 extends downward from the connection point with the brake 22 and is rotatably connected to a permanent magnet section 32 located directly below the brake 22 to which the operating rod 34 is connected.

[0034] As shown in Figure 2, when the emergency stop device 20 is in a non-operating state, the permanent magnet part 32 is attracted to the electromagnet part 33. Therefore, since the permanent magnet part 32 is separated from the elevator car guide rail 5A, there is a gap between the permanent magnet part 32 and the elevator car guide rail 5A. Consequently, the permanent magnet part 32, together with the operating rod 34, is rotatable around the connection between the braker 22 and the operating rod 34, and the permanent magnet part 32 is movable between the electromagnet part 33 and the elevator car guide rail 5A.

[0035] Within the housing 31, a sliding member 37 made of a low-friction material such as resin is provided on the side of the elevator car guide rail 5A opposite to the side where the permanent magnet portion 32 is located. The sliding member 37 can support the elevator car guide rail 5A in an emergency when the permanent magnet portion 32 is repelled by the electromagnet portion 33 and collides with the elevator car guide rail 5A.

[0036] In this embodiment, a plate-shaped or sheet-shaped permanent magnet piece 51 is fixedly mounted on the upper part of the housing 21 of the emergency stop device 20, adjacent to the elevator car guide rail 5A. A gap is provided between the permanent magnet piece 51 and the elevator car guide rail 5A so that the permanent magnet piece 51 and the elevator car guide rail 5A do not come into contact while the elevator car 3 is in motion or stopped.

[0037] The pair of flat surfaces on the front and back of the permanent magnet piece 51, perpendicular to the thickness direction, constitute the magnetic pole surfaces. One flat surface is fixed to the upper part of the housing 21, while the other flat surface is exposed in the elevator shaft.

[0038] Figure 3 is a top view of the emergency stop device 20 shown in Figure 2. In the figure, the elevator car guide rail is shown with a T-shaped cross-section.

[0039] As shown in Figure 3, the permanent magnet pieces 51 are provided adjacent to the notch and the head of the T-shaped elevator car guide rail 5A, on both sides of the head of the T-shaped elevator car guide rail 5A that passes through the notch in the housing 21.

[0040] In this embodiment, the permanent magnet piece 51 is placed on the housing 21 such that its flat surface is in contact with the upper surface of the housing 21 of the emergency stop device 20. As shown in Figure 4, the flat surface of the permanent magnet piece 51 may cover a portion of the notch.

[0041] Various types of magnets, such as metal magnets, resin magnets, and rubber magnets, can be used as the permanent magnet piece 51.

[0042] Figure 4 is a diagram showing the positional relationship between the permanent magnet section 32 and the electromagnet section 33 in this embodiment.

[0043] The electromagnet section 33 comprises a magnetic core 33a and coils 33b positioned above and below the magnetic core 33a. One of the magnetic pole surfaces of the magnetic core 33a and one of the magnetic pole surfaces of the permanent magnet section 32 face each other. The other magnetic pole surface of the permanent magnet section 32 faces the side of a guide rail for a train car, which is not shown in Figure 3.

[0044] Figure 5 is a diagram showing the operation of the emergency stop device 20 and the operating mechanism 30 in an emergency in this embodiment. The operation state progresses along the arrows in the figure.

[0045] As shown in the left figure, under normal conditions, the brake element 22 is located in a non-braking position at the lower part of the emergency stop device 20, away from the guide member 23. The permanent magnet part 32 is attracted to the magnetic pole surface of the electromagnet part 33 by the electromagnetic force generated by the electromagnet part 33. Therefore, the position of the brake element 22 is maintained in the non-braking position of the emergency stop device 20, which is fixed to the elevator car 3. In other words, the brake element 22 is fixed to the elevator car 3 via the operating rod 34.

[0046] Furthermore, the coil 33b (Figure 4) of the electromagnet unit 33 is normally energized to attract the permanent magnet unit 32.

[0047] As described above, when the safety control device determines that the descending speed of the elevator car 3 has reached a second overspeed (for example, a speed not exceeding 1.4 times the rated speed), it outputs a command signal to activate the operating mechanism 30. When the control device of the electromagnet unit 33 receives the command signal, it flows current through the coil 33b (Figure 4) in the opposite direction to the normal direction. As a result, the permanent magnet unit 32 receives a repulsive force from the electromagnet unit 33 and moves away from the electromagnet unit 33 towards the elevator car guide rail 5A. Therefore, as shown in the central figure, the permanent magnet unit 32 is attracted to the elevator car guide rail 5A by the magnetic force of the permanent magnet unit 32.

[0048] Therefore, the brake 22 is released from its attachment to the elevator car 3 and is fixed to the elevator car guide rail 5A via the operating rod 34.

[0049] As the elevator car 3 continues to descend while the brakes 22 remain fixed to the elevator car guide rail 5A, the brakes 22 are relatively pushed up from the non-braking position at the bottom of the emergency stop device 20 (center diagram) to the braking position where they are sandwiched between the pair of guide members 23, as shown in the right diagram. At the braking position, the pair of brakes 22 are squeezed by the pair of guide members 23, thus gripping the elevator car guide rail 5A. As a result, the elevator car 3 is braked by the frictional force generated between each brake 22 and the elevator car guide rail 5A.

[0050] The permanent magnet piece 51 attracts magnetic foreign matter at the notch on the upper surface of the housing (labeled "21" in Figures 2 and 3) that is exposed in the elevator shaft, and at a position adjacent to the elevator car guide rail 5A. This prevents magnetic foreign matter from entering the operating mechanism 30 via the emergency stop device 20. Therefore, the adhesion of magnetic foreign matter to the magnetic pole surface of the permanent magnet part 32 of the operating mechanism 30 is suppressed.

[0051] As a result, as described above, a decrease in the attractive force when the permanent magnet section 32 is attracted to the elevator car guide rail 5A is prevented. Therefore, the reliability of the operation of the emergency stop device 20 is improved.

[0052] Figure 6 is a diagram showing the external appearance of the operating mechanism in an elevator device, which is a first modified example of this embodiment. Figure 6 corresponds to a partially enlarged view of Figure 1 (viewed by arrow A).

[0053] In this modified example, in addition to the permanent magnet piece 51 in the above-described embodiment, a plate-shaped or sheet-shaped permanent magnet piece 52 is further fixedly provided on the outer surface of the dustproof cover member 40 that covers the side of the operating mechanism 30. The permanent magnet piece 52 is provided on both sides of the elevator car guide rail 5A that passes through the center of the housing 31, along the longitudinal direction of the elevator car guide rail 5A and adjacent to the elevator car guide rail 5A.

[0054] The pair of flat surfaces on the front and back of the permanent magnet piece 51, perpendicular to the thickness direction, constitute the magnetic pole surfaces. One flat surface is fixed to the outer surface of the cover member 40, while the other flat surface is exposed inside the elevator shaft.

[0055] According to this modified example, the permanent magnet piece 52 attracts magnetic foreign matter, similar to the permanent magnet piece 51 described above, thus suppressing the intrusion of magnetic foreign matter into the operating mechanism 30 from the side. As a result, the adhesion of magnetic foreign matter to the magnetic pole surface of the permanent magnet part 32 of the operating mechanism 30 is suppressed, improving the reliability of the operation of the emergency stop device 20.

[0056] Figure 7 is a diagram showing the mechanical configuration of the permanent magnet section and the electromagnet section in an elevator device, which is a second modified example of this embodiment.

[0057] In this modified example, the operating mechanism 30 is provided above the emergency stop device 20. The individual configurations of the emergency stop device 20 and the operating mechanism 30 are the same as in the above-described embodiment (Figure 2).

[0058] In this modified example, when the permanent magnet section 32 and the electromagnet section 33 operate in an emergency, similar to the embodiment, the braker 22 is relatively pulled up from the non-braking position at the bottom of the emergency stop device 20 to the braking position where it is sandwiched between the guide members 23.

[0059] In this embodiment, a plate-shaped or sheet-shaped permanent magnet piece 53 is fixedly mounted on the upper part of the housing 31 of the operating mechanism 30, adjacent to the elevator car guide rail 5A. A gap is provided between the permanent magnet piece 53 and the elevator car guide rail 5A so that the permanent magnet piece 53 and the elevator car guide rail 5A do not come into contact while the elevator car 3 is in motion or stopped.

[0060] The pair of flat surfaces on the front and back of the permanent magnet piece 53, perpendicular to the thickness direction, constitute the magnetic pole surfaces. One flat surface is fixed to the upper part of the housing 31, and the other flat surface is exposed in the elevator shaft.

[0061] Figure 8 is a top view of the operating mechanism 30 in Figure 7.

[0062] As shown in Figure 8, the permanent magnet pieces 53 are provided adjacent to the notch and the head of the T-shaped elevator car guide rail 5A, on both sides of the head of the T-shaped elevator car guide rail 5A that passes through the notch in the housing 31.

[0063] In this modified example, the permanent magnet piece 53 is placed on the housing 31 such that its flat surface is in contact with the upper surface of the housing 31 of the operating mechanism 30. The flat surface of the permanent magnet piece 53 may also cover a portion of the notch.

[0064] According to the above embodiment, by providing a permanent magnet piece with its magnetic pole surface exposed inside the elevator shaft in the emergency stop system, which consists of an emergency stop device 20 and an operating mechanism 30 for the emergency stop device 20, the intrusion of magnetic foreign matter into the operating mechanism 30 is prevented. This improves the reliability of the operation of the emergency stop device 20.

[0065] Furthermore, according to the inventors' research, magnetic foreign objects often fall from above the elevator car or approach the elevator car from above as the car moves. For this reason, as shown in the above embodiment (Figure 2) and the second modified example (Figure 7), by providing a permanent magnet piece on the upper part of the emergency stop system, which consists of the emergency stop device 20 and the operating mechanism 30, the intrusion of magnetic foreign objects into the operating mechanism 30 can be prevented more reliably.

[0066] It should be noted that the present invention is not limited to the embodiments described above, and various modifications are included. For example, the embodiments described above are described in detail to make the present invention easier to understand, and are not necessarily limited to those having all the configurations described. In addition, it is possible to add, delete, or replace some of the configurations in the embodiments with other configurations.

[0067] For example, the permanent magnet pieces 51, 52, and 53 may be provided in a detachable manner. This makes it easier to replace the permanent magnet pieces 51 and 52 during maintenance work. Alternatively, of the permanent magnet pieces 51 and 52 in the first modified example, only the permanent magnet piece 52 may be provided.

[0068] Furthermore, an electromagnet may be used instead of the permanent magnet section 32 in the operating mechanism 30. Also, the permanent magnet section 32 and the electromagnet section 33 may be referred to as an electromagnet section and a permanent magnet section, respectively.

[0069] Furthermore, the elevator system may have a machine room, or it may be a so-called machine room-less elevator. [Explanation of symbols]
