[0005] Patent Document 1: Japanese Patent Application Publication No. 2004-26424 Summary of the Invention

[0006] The problem that the invention aims to solve

[0007] The reel has a supply port for supplying lubricant to the bearing. Lubricant is periodically supplied to the bearing through this port. During this process, some lubricant seeps out from the bearing and adheres to the side of the reel. Furthermore, the lubricant adhering to this side drips downwards, causing contamination of cables and other materials, and therefore must be removed. However, because the bearing mounting side (center side) of the reel is covered by a mounting plate on the shaft of the reel, it is difficult to reach by hand. Therefore, cleaning requires labor and time, making it difficult to thoroughly clean the side of the reel.

[0008] Therefore, the purpose of this invention is to provide an auxiliary tool and a method for cleaning a reverse rope wheel, which can easily perform cleaning operations on the side of the reverse rope wheel and easily clean the side of the reverse rope wheel.

[0009] Methods for solving problems

[0010] To address the aforementioned issues, the present invention provides a cleaning aid for a reverse rope wheel in an elevator for cleaning a reverse rope wheel in an elevator assembly comprising a reverse rope wheel and a mounting plate. The shaft portion of the reverse rope wheel is mounted on the mounting plate, and the mounting plate is configured to cover at least a portion of the side surface of the reverse rope wheel at intervals. The cleaning aid includes: a fixing portion for fixing to the mounting plate; and a cleaning portion connected to the fixing portion by means of a connecting portion, and capable of contacting the side surface while the fixing portion is fixed to the mounting plate.

[0011] According to the present invention, with the cleaning part in contact with the side of the anti-roll wheel, the fixing part can be fixed to the mounting plate on which the anti-roll wheel is fixed. Therefore, in this state, the lubricant adhering to the side can be easily scraped off by the cleaning part simply by automatically rotating the anti-roll wheel. Thus, cleaning operations on the side that is difficult to reach by hand due to being covered by the mounting plate can be easily performed, and the side can be easily cleaned.

[0012] Alternatively, in this invention, the connecting portion may include an axial extension portion that extends substantially parallel to the axial direction of the anti-cord pulley while the fixing portion is fixed to the mounting plate, and an axial extension portion that extends and retracts along the axial direction.

[0013] According to the above structure, the axial length of the axial extension can be varied according to the distance between the side of the anti-cord wheel and the mounting plate. By adjusting the axial length of the axial extension, the cleaning part can be brought into contact with the side of the anti-cord wheel. Therefore, the anti-cord wheel cleaning accessory can be applied to multiple anti-cord wheel devices with different distances between the side of the anti-cord wheel and the mounting plate, thereby improving the versatility of the anti-cord wheel cleaning accessory.

[0014] Alternatively, in this invention, the connecting portion may include a vertically extending portion that extends in a vertical direction substantially perpendicular to the extending direction of the axially extending portion while the fixing portion is fixed to the mounting plate, and a vertically extending portion that extends and retracts the vertically extending portion in the vertical direction.

[0015] Based on the above structure, the length of the vertical extension can be adjusted according to the specifications of the anti-cord pulley. Therefore, the cleaning part can be positioned appropriately to contact the side of the anti-cord pulley according to the specifications of each anti-cord pulley, thereby increasing the cleaning effect on the side of the anti-cord pulley.

[0016] Furthermore, in this invention, one or more replaceable cleaning parts with a length different from the cleaning part may be provided, and the cleaning part and the replaceable cleaning part can be disassembled and assembled relative to the connecting part.

[0017] If the diameter of the anti-roller wheel increases, the amount of lubricant seeping from the rolling bearing also tends to increase. In contrast, according to this structure, a cleaning section of appropriate length can be selected based on the specifications of the anti-roller wheel and installed at the connecting part. Therefore, the cleaning effect of the cleaning section on the side of the anti-roller wheel can be increased.

[0018] Furthermore, in this invention, a sheet-like component with a magnet may also be provided, which has: a sheet-like component; a first magnet fixed to one end of two opposite ends in one direction of the sheet-like component; and a second magnet fixed to the other end of the two ends.

[0019] According to the above structure, the first magnet can be fixed to the outer side of one of a pair of mounting plates arranged with the shaft of the anti-reverse pulley fixed thereon and the pulley clamped by the anti-reverse pulley, and the second magnet can be fixed to the outer side of the other mounting plate. Furthermore, in this state, the underside of the anti-reverse pulley can be covered with a sheet-like component. Therefore, the sheet-like component can receive lubricant scraped off from the anti-reverse pulley, preventing the scraped lubricant from contaminating the area below the anti-reverse pulley.

[0020] Furthermore, the anti-cord wheel cleaning method of the present invention is a method for cleaning the anti-cord wheel of an elevator using the anti-cord wheel cleaning auxiliary tool of the present invention, comprising: a fixing step, wherein the fixing part is fixed to a mounting plate while the cleaning part of the anti-cord wheel cleaning auxiliary tool is in contact with the side of the anti-cord wheel, the mounting plate being configured to cover at least a portion of the side of the anti-cord wheel when separated from it; and a rotation step, wherein the anti-cord wheel is rotated after the fixing step.

[0021] According to the present invention, the side cleaning operation of the anti-roll wheel can be easily performed, and the side of the anti-roll wheel can be cleaned.

[0030] Figure 7 It is to have and in Figure 2 The diagram illustrates different structures of the anti-rope pulley device. Detailed Implementation

[0031] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Furthermore, in cases where multiple embodiments or variations are included below, it is conceivable from the outset to construct new embodiments by appropriately combining their characteristic parts. Additionally, in the following embodiments, the same reference numerals are used to denote the same structures in the drawings, and repeated descriptions are omitted. Furthermore, since multiple drawings include schematic diagrams, the aspect ratios of the components (length, width, and height) may not be consistent between different drawings.

[0032] Figure 1 This is a schematic structural diagram of an example of elevator 1, including anti-cord pulleys 6-9. (See diagram for example.) Figure 1 As shown, elevator 1 includes a car 2, cables 3, a counterweight 4, a traction machine 5, a first deflector sheave 6, a second deflector sheave 7, a third deflector sheave 8, a fourth deflector sheave 9, and a control panel 10. The car 2 is disposed within a shaft 11 extending vertically within a building. The traction machine 5 and the control panel 10 are located in a pit 12 at the lower part of the shaft 11. Furthermore, the first to third deflector sheaves 6, 7, and 8 are rotatably suspended and fixed to the ceiling of the shaft 11 at intervals along the depth direction of the shaft 11. The fourth deflector sheave 9 is installed on the counterweight 4 disposed within the shaft 11. Additionally, in… Figure 1 In this example, we will use a machine-room-less elevator with the traction machine 5 installed in the pit 12 as an example. However, the elevator can also be configured to have a machine room at the top of the shaft, with the traction machine installed in the machine room.

[0033] One end of the cable 3 is fixed to the upper part of the car 2. Starting from the car 2, the cable 3 is wound in the following sequence: first anti-corrosion pulley 6, second anti-corrosion pulley 7, traction machine 5, third anti-corrosion pulley 8, and fourth anti-corrosion pulley 9. The other end of the cable 3 is fixed to the ceiling of the hoistway 11. The weight of the counterweight 4 is set to achieve balance between the counterweight 4 and the car 2, which is connected to the counterweight 4 via the cable 3. The control panel 10 receives signals from call buttons (not shown) located at each floor's landing 14 to call the car 2, and from destination floor buttons (not shown) located inside the car 2 to specify the destination floor. Based on these signals, the control panel 10 controls the rotation direction and speed of the traction machine 5's motor 5a, thereby raising and lowering the car 2.

[0034] Figure 2 This is a front view of the anti-rope wheel device 20, which is equipped with an anti-rope wheel cleaning accessory 50 according to an embodiment of the present invention, viewed from the radially outer side of the first anti-rope wheel (hereinafter referred to as the anti-rope wheel) 6 included in the anti-rope wheel device 20. Furthermore, Figure 3 From Figure 2 The side view of the anti-rope wheel device 20 with the anti-rope wheel cleaning aid 50 installed, viewed in the direction indicated by the middle arrow A.

[0035] like Figure 2 As shown, the anti-cord pulley 6 includes a pulley 40, a shaft 41, and a rolling bearing (not shown). The pulley 40 has a groove 42 for winding the cable 3, and the rolling bearing supports the pulley 40 so that it can rotate freely relative to the shaft 41. In addition to the anti-cord pulley 6, the anti-cord pulley device 20 also includes an anti-cord pulley mounting part 21, which includes a pair of metal mounting plates 22 for fixing the shaft 41 of the anti-cord pulley 6. The mounting plates 22 are plate-shaped portions arranged in the anti-cord pulley mounting part 21 that are substantially parallel to the side surface 43 of the pulley 40.

[0036] When the anti-rope pulley device 20 is installed in the specified position, Figure 2 The upper side of the paper surface aligns with the upper side in the vertical direction. Furthermore, the upper end of the mounting plate 22 is connected to a component directly mounted on the ceiling side of the shaft 11, or the upper end of the mounting plate 22 is indirectly fixed to the shaft 11 by means of one or more other components mounted on the shaft 11, thus remaining stationary relative to the shaft 11. One side of the mounting plate 22 is located on one axial side of the sheave 40, axially spaced apart from the sheave 40, while the other side of the mounting plate 22 is located on the other axial side of the sheave 40, axially spaced apart from the sheave 40.

[0037] One end of the shaft portion 41 of the counter-rotating pulley 6 protrudes axially from the pulley 40, and the other end of the shaft portion 41 protrudes axially from the pulley 40. One end of the shaft portion 41 is fixed to a mounting plate 22 on one side, and the other end of the shaft portion 41 is fixed to a mounting plate 22 on the other side. Thus, the counter-rotating pulley 6 is rotatably mounted on a pair of mounting plates 22, resulting in the pulley 40 being rotatably mounted on the hoistway 11.

[0038] like Figure 2 As shown, the anti-cord sweeping aid (hereinafter referred to as the aid) 50 has an aid body 51 and a sheet-like component 52 with a magnet. The structure of the aid body 51 will be explained later. Figures 4 to 6 Please provide a detailed explanation. For example... Figure 2 As shown, according to the specifications of the anti-rope pulley device 20, the auxiliary tool 50 is installed on the lower end of the mounting plate 22.

[0039] like Figure 2 and Figure 3 As shown, the magnetic sheet member 52 includes a sheet member 53, a plurality of first magnets 54, and a plurality of second magnets 55. The sheet member 53 has a generally rectangular (strip) shape. Furthermore, the plurality of first magnets 54 are fixed at intervals in the width direction to one end of one side surface of the sheet member 53 in the length direction, and the plurality of second magnets 55 are fixed at intervals in the width direction to the other end of one side surface of the sheet member 53 in the length direction.

[0040] like Figure 2 and Figure 3 As shown, the first magnet 54 is magnetically fixed to the outer end face of one mounting plate 22, and the second magnet 55 is magnetically fixed to the outer end face of another mounting plate 22. Figure 3 As shown, in this embodiment, the sheet-like component 53 is configured to cover most of the lower end of the rope pulley 40 and is configured to completely overlap with the auxiliary body 51 fixed to the mounting plate 22 when viewed from the vertical direction. However, it is preferable that the sheet-like component is configured to cover the entire lower end of the rope pulley, and preferably, that the sheet-like component is configured to completely overlap with the rope pulley and the auxiliary body fixed to the mounting plate when viewed from the vertical direction. Furthermore, in Figure 2 and Figure 3 In the example shown, the first and second magnets 54 and 55 are fixed to the mounting plate 22 without clamping the sheet component 53, but the first and second magnets can also be fixed to the mounting plate with the sheet component clamped.

[0041] Next, the structure of the assistive device body 51 will be described in detail. Figure 4 This is the front view of the main body 51 of the assistive device. Figure 2The front view shown is only an enlarged view of the main body 51 of the assistive device. Furthermore, Figure 5 From Figure 4 A plan view of a portion of the assistive device body 51 viewed in the direction indicated by the middle arrow B. (See image below.) Figure 4 As shown, the main body 51 of the assistive device includes a fixing part 60, a connecting part 75, and a cleaning part 95.

[0042] The fixing part 60 comprises an integral fixing body 61, a pressing part 62, and a wing screw 63. The fixing body 61 includes a first flat plate 65, a second flat plate 66, a third flat plate 67, and a connecting mounting structure 68. The first to third flat plate parts 65-67 have a flat plate shape. The second flat plate part 66 and the third flat plate part 67 extend from one side 65a of the first flat plate part 65 in a vertical direction that is approximately perpendicular to the first flat plate part 65, in a state that is substantially parallel to each other. In addition, the pressing part 62 has a circular pressing plate 69 and a wing screw 70. The end of the shaft portion 70a of the wing screw 70 engages with the back side (the side opposite to the pressing surface) of the pressing plate 69. The third flat plate part 67 has a threaded hole, and the external thread provided on the shaft portion 70a of the wing screw 70 engages with the threaded hole.

[0043] After mounting plate 22 (refer to) Figure 2 With the lower end of the mounting plate 22 positioned between the second flat plate 66 and the pressing plate 69, tighten the wing screw 70 to move the pressing plate 69 toward the second flat plate 66. Then, use the pressing plate 69 to secure the lower end of the mounting plate 22 to the second flat plate 66, thereby fixing the fixing part 60 to the lower end of the mounting plate 22.

[0044] The connecting mounting structure 68 connects to the other side 65b of the first flat plate portion 65. The connecting mounting structure 68 has a through-hole defining portion 72, which, together with the other side 65b, forms a through hole with a generally rectangular cross-section. Although not shown, the through-hole defining portion 72 has a threaded hole on a plate-shaped portion 72a opposite to the first flat plate portion 65 along its normal direction. Furthermore, the external thread provided on the shaft portion of the wing screw 63 engages with this threaded hole.

[0045] The connecting portion 75 connects the fixing portion 60 and the cleaning portion 95, extending from the fixing portion 60 to the cleaning portion 95. The connecting portion 75 has an axial extension portion 76, a vertical extension portion 77, and a connecting portion 78. The axial extension portion 76 is formed by a portion of a first rod-shaped member 73 extending in a straight direction, i.e., in one direction. The cross-sectional shape of the first rod-shaped member 73 is approximately rectangular. The first rod-shaped member 73 is inserted through into the through insertion hole defined by the through insertion hole defining portion 72. By tightening the wing screw 63, the end of the wing screw 63 presses the first rod-shaped member 73 against the other side 65b of the first flat plate portion 65, securing the first rod-shaped member 73 to the first flat plate portion 65, thereby fixing the first rod-shaped member 73 to the through insertion hole defining portion 72. Furthermore, the length of the axial extension portion 76 can be adjusted by appropriately adjusting the length position of the first rod-shaped member 73 in contact with the wing screw 63. The through-hole defining portion 72 and the wing screw 63 constitute an axial telescopic portion. Furthermore, in the first rod-shaped member 73, the portion fixed by the through-hole defining portion 72 and the wing screw 63 constitutes one end of the axial extension portion 76.

[0046] like Figure 5 As shown, the connecting portion 78 includes a connecting body 79, a first wing screw 80, and a second wing screw 81. The connecting body 79 includes first and second through holes 82 and 83 extending in directions substantially perpendicular to each other. The first through hole 82 has a substantially rectangular cross-section, and a first rod-shaped member 73 is inserted through the first through hole 82. The first through hole 82 is defined by a through hole defining portion 84, which has a threaded hole in a sidewall portion 85 located on the side opposite to the side of the second through hole 83. The external thread of the shaft portion of the first wing screw 80 is screwed into the threaded hole of the sidewall portion 85, and the end portion of the shaft portion is used to press the first rod-shaped member 73 toward the opposing sidewall portion 86 opposite to the sidewall portion 85. In this way, the first rod-shaped member 73 is fixed to the connecting body 79 by fastening the first rod-shaped member 73 to the opposing sidewall portion 86. In the first rod-shaped member 73, the portion fixed to the joint 78 constitutes the other end of the axial extension 76.

[0047] like Figure 5 As shown, the second through hole 83 is a cylindrical hole. Furthermore, refer to... Figure 4 The vertical extension 77 is formed by a portion of the second rod-shaped member 74, which is composed of a round rod member, and is inserted through the second through hole 83. (Refer to...) Figure 5The cylindrical portion 87 defining the second through hole 83 has a threaded hole extending radially. The external thread of the shaft portion of the second wing screw 81 is screwed into the threaded hole of the cylindrical portion 87, and the end portion of the shaft portion is used to press the second rod-shaped member 74 against the inner circumferential surface of the second through hole 83. Thus, by fastening the second rod-shaped member 74 to the inner circumferential surface of the second through hole 83, the second rod-shaped member 74 is fixed to the connecting body 79. The length of the vertical extension 77 is adjusted by appropriately adjusting the length position of the second rod-shaped member 74 in contact with the second wing screw 81. The cylindrical portion 87 and the second wing screw 81 constitute a vertical telescopic portion. Furthermore, in the second rod-shaped member 74, the portion fixed to the connecting portion 78 constitutes one end of the vertical extension 77.

[0048] like Figure 4 As shown, the cleaning part 95 is detachably mounted to the end 89 of the second rod-shaped member 74 on the side opposite to the connecting part 78. More specifically, as... Figure 6 As shown in (a), a bottomed cylindrical hole 93 is provided at the end 89 of the second rod-shaped member 74. Furthermore, referring to… Figure 6 (b) The cleaning part 95 is fixed to the other end of the mounting shaft 94 with one end exposed. More specifically, for example, the cleaning part 95 has a mounting recess (not shown) consisting of a bottomed cylindrical hole or the like, and the other end of the mounting shaft 94 is fixed to the mounting recess by a fixing means, such as adhesive or pressing.

[0049] Reference Figure 6 (a) and Figure 6 (b) By pressing one end 94a exposed in the mounting shaft 94 into the cylindrical hole 93 of the second rod-shaped member 74, the mounting shaft 94 is fixed to the second rod-shaped member 74, resulting in the cleaning part 95 being fixed to the second rod-shaped member 74. When one end of the mounting shaft 94 is fully pressed into the cylindrical hole 93, the end of the second rod-shaped member 74 on the side opposite to the connecting part 78 constitutes the other end of the vertically extending part 77. The cleaning part 95 is preferably made of a rubber scraper, brush, sponge, or broom, but it can be made of any material as long as it is capable of scraping off lubricant such as grease adhering to the side of the sheave 40.

[0050] In the above structure, for example, the auxiliary tool 50 is used to clean the anti-rope wheel 6 in the following order. First, as... Figure 4 As shown, a cleaning part 95 is installed at one end of the second rod-shaped member 74, and the other side of the second rod-shaped member 74 is installed at the connecting part 78. In addition, the other side of the first rod-shaped member 73 is installed at the connecting part 78.

[0051] Next, the first rod-shaped member 73 is inserted through one end into the through hole of the connecting mounting structure 68 of the fixing part 60, and the lower end of the mounting plate 22 is positioned between the pressing plate 69 of the fixing part 60 and the second flat plate part 66. Then, in this state, the wing screw 70 is tightened, and the lower end is secured to the second flat plate part 66 with the pressing plate 69, thus fixing the fixing part 60 to the mounting plate 22.

[0052] Next, press the first rod-shaped component 73 toward the sheave 40 until the cleaning part 95 contacts the side 43 of the sheave 40. With the cleaning part 95 in contact with the side 43 of the sheave 40, tighten the wing screw 63 to fix the connecting part mounting structure 68 to the first rod-shaped component 73, thereby completing the fixation of the auxiliary body 51 to the anti-sheave device 20.

[0053] Next, the first magnet 54 with the magnetic sheet component 52 is fixed to the outer end face of one mounting plate 22, and the second magnet 55 is fixed to the outer end face of the other mounting plate 22. With the magnetic sheet component 52 fixed to the pair of mounting plates 22, the sheet component 53 is configured to completely overlap with the auxiliary body 51 fixed to the mounting plate 22 when viewed from the vertical direction. By fixing the first rod component 73 to the pair of mounting plates 22, the auxiliary 50 is fixed to the anti-rope pulley device 20.

[0054] Finally, with the auxiliary device 50 fixed to the anti-rollover device 20, the roll sheave 40 is rotated by moving the elevator car 2. This rotation of the roll sheave 40 is, for example, performed by a worker on the car 2 using a portable switch. As the roll sheave 40 rotates, the cleaning part 95 moves relative to the side 43 of the roll sheave 40 while in contact with the side 43. This relative movement scrapes off the lubricant adhering to the side 43 downwards. It is preferable that the roll sheave 40 rotates at least two revolutions to sufficiently remove the lubricant. The fallen lubricant is collected by the sheet-like component 53, allowing for cleaning of the anti-rollover device 6 without polluting the external environment.

[0055] As described above, the auxiliary tool 50 is used to clean the anti-cord pulley 6 included in the anti-cord pulley device 20 of the elevator 1. Furthermore, the anti-cord pulley device 20 includes a mounting plate 22, on which the shaft portion 41 of the anti-cord pulley 6 is mounted. Additionally, the mounting plate 22 covers at least a portion of the side surface 43 of the anti-cord pulley 6 at intervals. Furthermore, the auxiliary tool 50 includes: a fixing portion 60 for fixing to the mounting plate 22; and a cleaning portion 95 connected to the fixing portion 60 via a connecting portion 75, and capable of contacting the side surface 43 while the fixing portion 60 is fixed to the mounting plate 22.

[0056] Therefore, with the cleaning part 95 in contact with the side 43 of the anti-roll wheel 6, the fixing part 60 can be fixed to the mounting plate 22 on which the anti-roll wheel is fixed. Thus, in this state, by simply rotating the anti-roll wheel 6 automatically, the cleaning part 95 can easily scrape off the lubricant adhering to the side 43. As a result, cleaning operations on the side 43, which is difficult to reach by hand due to being covered by the mounting plate 22, can be easily performed, and the side 43 can be cleaned thoroughly.

[0057] Furthermore, the connecting portion 75 may also include an axial extension portion 76 that extends substantially parallel to the axial direction of the anti-cord pulley 6 while the fixing portion 60 is fixed to the mounting plate 22, and an axial extension portion that allows the axial extension portion 76 to extend and retract axially.

[0058] According to the above structure, the axial length of the axial extension 76 can be freely changed according to the distance between the side 43 of the anti-cord wheel 6 and the mounting plate 22. By adjusting the axial length of the axial extension 76, the cleaning part 95 can be brought into contact with the side 43 of the anti-cord wheel 6. Therefore, the auxiliary tool 50 can be applied to multiple anti-cord wheel devices 20 with different distances between the side 43 of the anti-cord wheel 6 and the mounting plate 22, thereby improving the versatility of the auxiliary tool 50.

[0059] Furthermore, the connecting portion 75 may also include a vertically extending portion 77 that extends in a vertical direction substantially perpendicular to the extending direction of the axially extending portion 76 while the fixing portion 60 is fixed to the mounting plate 22, and a vertically extending portion that causes the vertically extending portion 77 to extend and retract in the vertical direction.

[0060] Based on the above structure, the length of the vertical extension 77 can be adjusted according to the specifications of the anti-roll wheel 6. Therefore, the cleaning part 95 can be made to contact the side surface 43 of the anti-roll wheel 6 at an appropriate position according to the specifications of the anti-roll wheel 6, thereby increasing the cleaning effect of the side surface 43 of the anti-roll wheel 6.

[0061] Furthermore, the auxiliary tool 50 may also have one or more replaceable cleaning parts with a length different from that of the cleaning part 95. Moreover, the cleaning part 95 and the replaceable cleaning parts can be attached and detached relative to the connecting part 75. Additionally, the replaceable cleaning part and... Figure 6 Compared to the cleaning section 95 shown in (b), it has a structure that differs only in length, so the illustration is omitted.

[0062] If the diameter of the anti-roller 6 increases, the amount of lubricant seeping from the rolling bearing also tends to increase. In contrast, according to this structure, a cleaning section 95 of appropriate length can be selected based on the specifications of the anti-roller 6, and the selected cleaning section 95 or a replacement cleaning section can be installed on the connecting section 75. Therefore, the cleaning effect of the cleaning section 95 or the replacement cleaning section on the side 43 of the anti-roller 6 can be increased.

[0063] In addition, the auxiliary device 50 may also include a sheet-like component 52 with magnets, which has: a sheet-like component 53; a first magnet 54 fixed to one end of two opposite ends in one direction of the sheet-like component 53; and a second magnet 55 fixed to the other end of the two ends.

[0064] According to the above structure, the first magnet 54 can be fixed to the outer side of one of the pair of mounting plates 22 arranged to clamp the rope pulley 42, and the second magnet 55 can be fixed to the outer side of the other mounting plate 22. Furthermore, in this state, the underside of the anti-roll rope pulley 6 can be covered with the sheet-like member 53. Therefore, the sheet-like member 53 can receive lubricant scraped off from the anti-roll rope pulley 6, preventing the scraped lubricant from contaminating the area below the anti-roll rope pulley 6.

[0065] Furthermore, the anti-reverse sheave cleaning method of the present invention is a method for cleaning the anti-reverse sheave 6 of the elevator 1 using the auxiliary tool 50 of the present invention. This anti-reverse sheave cleaning method includes a fixing step, in which the fixing part 60 is fixed to the mounting plate 22 while the cleaning part 95 of the auxiliary tool 50 is in contact with the side surface 43 of the anti-reverse sheave 6. The mounting plate 22 is configured to cover a portion of the side surface 43 of the anti-reverse sheave 6 while being separated from at least a portion of the side surface 43. Furthermore, the anti-reverse sheave cleaning method includes a rotation step after the fixing step, in which the anti-reverse sheave 6 is rotated. According to this structure, the cleaning operation of the side surface 43 of the anti-reverse sheave 6 can be easily performed, and the side surface 43 of the anti-reverse sheave 6 can be cleaned thoroughly.

[0066] Furthermore, the present invention is not limited to the above-described embodiments and their variations, and various improvements or modifications can be made within the scope of the claims and their equivalents.

[0067] For example, in the above embodiment, the case where the length of the axial extension 76 and the length of the vertical extension 77 are adjusted using wing screws 63 and 81 has been described. However, the length of the axial extension can also be adjusted by a structure in which bolts are fixed to the first flat plate portion via elongated holes provided in the first rod-shaped member. Furthermore, the length of the vertical extension can also be adjusted by a structure in which bolts are fixed to the main body of the joint portion via elongated holes provided in the second rod-shaped member.

[0068] Furthermore, the case where the length of the axial extension 76 of the auxiliary tool 50 can be adjusted has been described. However, it is also possible to make the length of the axial extension of the auxiliary tool fixed, and the auxiliary tool may also be a dedicated auxiliary tool for a reverse rope pulley device with a predetermined distance between the mounting plate and the side of the rope pulley. Alternatively, the auxiliary tool may also be a structure that allows for the assembly and disassembly of multiple cleaning parts of different sizes, and the axial length can be adjusted by changing the size of the cleaning parts.

[0069] Furthermore, the case where the length of the vertical extension 77 of the auxiliary tool 50 can be adjusted has been described. However, it is also possible that the length of the vertical extension of the auxiliary tool cannot be changed. Furthermore, the case where the cleaning unit 95 can be detached from the vertical extension 77 has been described, and the case where one or more replaceable cleaning units with a length different from the cleaning unit 95 can be detached from the vertical extension 77 has been described. However, the cleaning unit may also be non-detachable from the vertical extension.

[0070] Furthermore, the situation where the portion of the first rod-shaped member 73 that is coupled to the connecting body 79 can be changed has been described. However, the first rod-shaped member may also be integral with the connecting portion, or the first rod-shaped member may be a structure in which it cannot move relative to the connecting portion.

[0071] Furthermore, the case where the first rod-shaped member 73 has a generally rectangular cross-section and the second rod-shaped member 74 is a round rod-shaped member has been described. However, the cross-sectional shapes of the first and second rod-shaped members can be any shape, such as square, rectangular, circular, semi-circular, or polygonal.

[0072] Furthermore, the case where the assistive device 50 has a magnetic sheet-like component 52 has been described. However, the assistive device may not have a magnetic sheet-like component, and the cleaning operation of the assistive device 50 may be performed with the sheet-like component positioned below the assistive device 50.

[0073] Furthermore, the case of using the auxiliary tool 50 to clean the anti-reverse rope sheave 6 suspended in the ceiling of the hoistway 11 has been described. However, the auxiliary tool of the present invention can also be used to clean the anti-reverse rope sheave provided on the bottom side of the car. Furthermore, the case of the auxiliary tool body 51 being fixed to the lower end of the mounting plate 22 has been described, but the auxiliary tool body can also be fixed to the upper end of the mounting plate.

[0074] In detail, such as Figure 7 As shown in the diagram viewed from the radially outer side of the anti-cord sheave 106, the elevator 101 may also have a pair of guide rails 102 arranged substantially parallel to each other and guiding the car or counterweight. Furthermore, the plate-shaped base 103 may be fixed to the pair of guide rails 102 in a manner that extends horizontally.

[0075] Alternatively, the shaft portion 108 of the anti-roll pulley 106 can be fixed to a pair of mounting plates 122, and the pair of mounting plates 122 can be directly fixed to the upper side of the base 103, or fixed to the upper side of a pair of height adjustment portions 105 fixed to the upper side of the base 103. Furthermore, the auxiliary body (not shown) can also be fixed to the upper end 122a of the pair of mounting plates 122. In summary, the auxiliary device of the present invention can achieve cleaning of any anti-roll pulley device including a pulley and a mounting plate disposed on at least one side of the pulley.
