Hereinafter, a cleaning tool for a sheave of an elevator hoist according to an embodiment will be described with reference to the attached drawings. In each embodiment, the same reference numerals are given to the same components.

Embodiment 1 FIG.
FIG. 1 is a diagram showing a state in which a sheave cleaning tool 10 for an elevator hoist according to Embodiment 1 is attached to a sheave 101 of an elevator hoist 100. As shown in FIG. 1, the sheave cleaning tool 10 of the elevator hoisting machine is attached to the upper part of the elevator hoisting machine 100 and cleans the sheave groove on the sheave 101 where the leash 102 is not applied. Note that the sheave cleaning tool 10 of the elevator hoisting machine is fixed to an attachment seating surface located at the upper part of the elevator hoisting machine 100 by a bolt (not shown).

FIG. 2 is a front view of the sheave cleaning tool 10 of the elevator hoist according to the first embodiment. FIG. 3 is a diagram showing an internal structure of the pressing component 34 of the movable portion 30 according to the sheave cleaning tool 10 of the elevator hoisting machine according to the first embodiment. As shown in FIG. 2, the sheave cleaning tool 10 of the elevator hoisting machine includes a housing 20, a movable unit 30, and a cleaning unit 40.

The housing 20 includes an upper plate 21, a lower plate 22, two side plates 23, two shafts 24, two upper end stoppers 25, two lower end stoppers 26, and a trapezoidal screw nut 27. The housing | casing 20 is a part which comprises the frame | skeleton of the sheave cleaning tool 10 of an elevator hoisting machine, and consists of materials, such as stainless steel and aluminum.

The upper plate 21 and the lower plate 22 are flat members, which are connected via a cylindrical shaft 24. Specifically, the upper plate 21 is fixed to the upper side of the two shafts 24 arranged in parallel by a method such as welding or screwing. The lower plate 22 is fixed to the lower side of the two shafts 24 arranged in parallel by a method such as welding or screwing.

The side plate 23 is a flat member. The two side plates 23 are fixed to both side surfaces of the upper plate 21 and the lower plate 22 so as to be arranged in parallel with the shaft 24. As a result, the upper plate 21, the lower plate 22, and the two side plates 23 have a square shape so as to surround the two shafts 24.

The upper end stopper 25 and the lower end stopper 26 play a role of regulating the operation range of the movable plate 33 of the movable unit 30 described later. The upper end stopper 25 and the lower end stopper 26 are ring-shaped metal members. The upper end stopper 25 is fixed to the upper part of each shaft 24, and the lower end stopper 26 is fixed to the lower end of each shaft 24.

The trapezoidal screw nut 27 is a cylindrical member that is located substantially at the center of the main surface of the upper plate 21 and penetrates the upper plate 21. On the inner surface of the cylinder formed by the trapezoidal screw nut 27, a thread groove for passing the trapezoidal screw is cut.

The movable part 30 includes a trapezoidal screw 31, a handle 32, a movable plate 33, and eight pressing parts 34.

The trapezoidal screw 31 is a cutting bolt with a trapezoidal thread. Further, the trapezoidal screw 31 is inserted into the trapezoidal screw nut 27 and is positioned so as to be arranged in parallel between the two shafts. The lower end of the trapezoidal screw 31 is located between the upper plate 21 and the lower plate 22, and the upper end of the trapezoidal screw 31 is located on the opposite side of the lower plate 22 with the upper plate 21 interposed therebetween.

The handle 32 is a disk-shaped member that is thick enough to be grasped by a hand. The handle 32 is fixed to the upper end of the trapezoidal screw 31. Then, by rotating the handle 32 clockwise as viewed from above, the trapezoidal screw 31 fixed to the handle 32 is also rotated, and the handle 32 and the trapezoidal screw 31 are moved downward. Further, by rotating the handle 32 counterclockwise as viewed from above, the trapezoidal screw 31 fixed to the handle 32 is also rotated, and the handle 32 and the trapezoidal screw 31 are moved upward.

The movable plate 33 is a flat plate member made of a material such as stainless steel or aluminum, and is connected to the lower end of the trapezoidal screw 31. Therefore, the movable plate 33 is located in a region surrounded by the upper plate 21, the lower plate 22, and the two side plates 23. Then, it moves up and down together with the trapezoidal screw 31 as the handle 32 rotates. However, since the movable plate 33 is connected to the trapezoidal screw 31 via a bearing provided on the movable plate 33, the movable plate 33 does not rotate together with the trapezoidal screw 31. Further, the two shafts 24 penetrate the movable plate 33. Thereby, the movable plate 33 moves up and down within the region surrounded by the upper plate 21, the lower plate 22, and the two side plates 23 along the shaft 24 with the shaft 24 as a guide. Further, the movable plate 33 is provided with a screw hole for fixing a pressing component 34 described later. Further, the movable plate 33 is provided with a rectangular hole for a cleaning claw mounting plate 41 described later. The main surface of the movable plate 33 is parallel to the main surfaces of the upper plate 21 and the lower plate 22.

The pressing component 34 is a member that applies a force that presses a cleaning claw, which will be described later, downward (in the direction of the depth of the rope), and is a plunger in the present embodiment. As shown in FIG. 3, the pressing component 34 includes an outer cylinder 35, an elastic member 36 and a contact member 37. Moreover, the press component 34 is provided corresponding to the number of the cleaning claws 42 which the cleaning tool 10 for sheaves of an elevator hoisting machine has. Specifically, two are provided for each of the four cleaning claws 42 of the sheave cleaning tool 10 of the elevator hoisting machine. Accordingly, the number of pressing parts 34 included in the sheave cleaning tool 10 of one elevator hoisting machine is eight. Among the plurality of pressing parts 34, in particular, a pressing part corresponding to a first cleaning claw 42a described later is a first pressing part 34a, and a pressing part corresponding to the second cleaning claw 42b is a second pressing part. This is referred to as a part 34b.

The outer cylinder 35 is a metal cylindrical member. However, the upper end side of the outer cylinder 35 is closed. Therefore, the outer cylinder 35 has a bottomed cylindrical shape. A screw thread is formed on the outer surface of the lower portion of the outer cylinder 35, and this portion is inserted into a screw hole formed in the movable plate 33. Thereby, the outer cylinder 35 is fixed to the movable plate 33 while penetrating the movable plate 33.

The expansion / contraction member 36 is a coil spring and is housed inside the outer cylinder 35. The upper end of the coil spring is located at the bottom of the outer cylinder 35, and the lower end is in contact with a contact member 37 described later.

The contact member 37 is a columnar member made of a resin such as POM. The upper end of the contact member 37 is in contact with the lower end of the elastic member 36. The upper part of the contact member 37 is located in the outer cylinder 35, and the lower part of the contact member 37 protrudes from the outer cylinder 35. Further, the lower portion of the contact member 37 protrudes below the movable plate 33. Note that the lower end of the contact member 37 has a slightly rounded shape in order to prevent the cleaning unit 40 from being damaged when in contact with the cleaning unit 40.

FIG. 4 is a cross-sectional view taken along the line AA in FIG. FIG. 5 is a cross-sectional view of the lower plate 22 and the cleaning claw attachment plate 41 for the sheave cleaning tool of the elevator hoisting machine according to the first embodiment.

As shown in FIG. 4, the cleaning unit 40 includes four cleaning claw attachment plates 41 and four cleaning claws 42. In the following description, among the four cleaning claws 42, the cleaning claw corresponding to the first tie groove 106a is referred to as the first cleaning claw 42a, and the cleaning claw corresponding to the second tie groove 106b is referred to as the second cleaning claw. This is referred to as a nail 42b.

The cleaning claw mounting plate 41 has a shape in which two rectangular parallelepipeds are stacked one above the other, and is a member made of stainless steel, aluminum, or the like. The upper surface of the rectangular parallelepiped located at the upper portion is in contact with the lower end of the contact member 37 of the pressing component 34. Further, as shown in FIG. 5, the upper rectangular parallelepiped 41 a is positioned above the lower plate 22. The lower rectangular parallelepiped 41 b is positioned so as to penetrate the lower plate 22. Specifically, a part of the rectangular parallelepiped 41 b is located in the hole H provided in the lower plate 22. Further, the other part of the rectangular parallelepiped 41 b protrudes above or below the movable plate 33. Here, the hole H provided in the lower plate 22 is slightly larger than the width of the rectangular parallelepiped 41b. Therefore, the rectangular parallelepiped 41 b can move up and down inside the hole H provided in the movable plate 33. However, the rectangular parallelepiped 41a cannot pass through the hole H provided in the lower plate 22 larger than the rectangular parallelepiped 41b. As a result, the cleaning claw attachment plate 41 is prevented from dropping through the hole H of the lower plate 22.

The cleaning claw 42 including the first cleaning claw 42a and the second cleaning claw 42b shown in FIG. 4 is a resin member. Further, the upper end of the first cleaning claw 42 a is fixed to the lower end of the cleaning claw mounting plate 41 with an adhesive or the like. The same applies to the second cleaning claw 42b and the other cleaning claws 42. Further, the first cleaning claw 42 a is configured such that when the sheave cleaning tool 10 of the elevator hoisting machine is attached to the sheave 101 of the elevator hoisting machine 100, the sheave 101 is driven by the force from the first pressing component 34 a. It is pressed against the rope groove 106a. Further, for the second cleaning claw 42b, when the sheave cleaning tool 10 of the elevator hoisting machine is attached to the sheave 101 of the elevator hoisting machine 100, the sheave is caused by the force from the second pressing component 34b. 101 is pressed against the leash groove 106b. As for the other cleaning claws 42, when the sheave cleaning tool 10 of the elevator hoisting machine is attached to the sheave 101 of the elevator hoisting machine 100, it is pressed against the tuft groove.

In the elevator hoisting machine sheave cleaning tool 10 configured as described above, it is possible to more reliably remove the dirt on the leve groove with a large amount of wear as compared with a conventional cleaning tool. Specifically, like a conventional cleaning tool, when a plurality of ropes are cleaned with a single spatula cleaning spatula, the cleaning spatula hits the bottom of the rope with a low amount of wear, and The cleaning spatula does not reach the bottom enough. As a result, it is not possible to sufficiently remove the dirt of the rope with a large amount of wear. On the other hand, in the sheave cleaning tool 10 of the elevator hoist, the pressing component 34 moves together with the movable plate 33. Accordingly, when the movable plate 33 is moved downward by operating the handle 32, the lower end of the contact member 37 of the pressing component 34 comes into contact with the upper surface of the cleaning claw mounting plate 41 of the cleaning unit 40. When the contact member 37 comes into contact with the cleaning claw mounting plate 41, the contact member 37 is pressed from the expansion / contraction member 36 located in the outer cylinder 35 of the pressing component 34 to press the cleaning claw mounting plate 41. As a result, the first cleaning claw 42a is pressed against the first rope groove 106a, and the second cleaning claw 42b is pressed against the second rope groove 106b. However, the elastic member 36, which is a coil spring, expands and contracts so that the first cleaning claw 42a and the second cleaning claw 42b correspond to the depths of the rope groove 106a and the rope groove 106b. Each cleaning claw mounting plate 41 to which the second cleaning claw 42b is fixed moves up and down. In this way, the first cleaning claw 42a fixed to the tip of the cleaning claw mounting plate 41 can move along the first tie groove 106a in the depth direction of the first tie groove 106a. . Similarly, the second cleaning claw 42b can move in the depth direction of the second rope groove 106b along the second rope groove 106b. Furthermore, since the first cleaning claw 42a and the second cleaning claw 42b are pressed by different pressing parts 34, the first cleaning claw 42a and the second cleaning claw 42b can move independently. it can. Thereby, in the sheave cleaning tool 10 of the elevator hoisting machine, the first cleaning claw 42a hits the bottom of the tight groove where the wear amount is shallow, and the second cleaning claw 42b hits the bottom of the tight groove where the wear amount is large. It is possible to prevent the situation that it does not reach enough. As a result, it is possible to more reliably remove the dirt on the rope groove with a large amount of wear as compared with a conventional cleaning tool. The other cleaning claws 42 included in the sheave cleaning tool 10 of the elevator hoist can also move in the depth direction in the rope groove, and each of the other cleaning claws 42 can move independently. Is possible. Accordingly, the first cleaning claw 42a, the second cleaning claw 42b, and the two other cleaning claws 42 can move independently.

Embodiment 2. FIG.
FIG. 6 is a diagram illustrating a state in which the sheave cleaning tool 10 A for the elevator hoist according to the second embodiment is attached to the sheave 101 of the elevator hoist 100. Moreover, FIG. 7 is the figure which looked at the cleaning nail | claw in the cleaning tool 10A for sheaves of the elevator hoisting machine which concerns on Embodiment 2 from the direction orthogonal to a leash groove. FIG. 8 is a view of a cleaning claw in a sheave cleaning tool 10 A of an elevator hoisting machine according to Embodiment 2 as viewed from a direction parallel to the rope groove. FIG. 9 is an enlarged view of the surface of the flat plate portion of the cleaning claw in the sheave cleaning tool 10A of the elevator hoist according to the second embodiment. FIG. 10 is a diagram illustrating components related to the cleaning claws of the sheave cleaning tool 10A of the elevator hoisting machine according to the second embodiment.

The difference between the elevator hoisting sheave cleaning tool 10A according to the second embodiment shown in FIG. 6 and the elevator hoisting sheave cleaning tool 10 according to the first embodiment is the cleaning claw. It is. More specific description will be given below. Hereinafter, in order to avoid redundant description, only the first cleaning claw 42a and the corresponding rope groove 106a among the plurality of cleaning claws provided in the sheave cleaning tool 10A of the elevator hoisting machine are described. As will be described, the second cleaning claw 42b and the other two cleaning claws 42 provided in the sheave cleaning tool 10A of the elevator hoisting machine have the same configuration as described below.

As shown in FIG. 7, the first cleaning claw 42 a of the sheave cleaning tool 10 A of the elevator hoisting machine that is Embodiment 2 includes a first flat plate portion 51, a second flat plate portion 52, and a third flat plate portion 52. It has the flat plate part 53, the flat plate part 54, the flat plate part 55, the space | interval member 60 pinched between each flat plate part, the pin 70, and the nut 72. Further, the first flat plate portion 51, the second flat plate portion 52, the third flat plate portion 53, the flat plate portion 54, and the flat plate portion 55 are made of a resin such as PPS and have a plate shape. Further, the first flat plate portion 51, the flat plate portion 54, the second flat plate portion 52, the flat plate portion 55, and the third flat plate portion 53 are arranged in a line along the rope groove 106 a of the sheave 101. . Here, the arrangement direction X is a direction in which the first flat plate portion 51, the flat plate portion 54, the second flat plate portion 52, the flat plate portion 55, and the third flat plate portion 53 are arranged. Then, the first flat plate portion 51 is located at one end in the arrangement direction X, and the second flat plate portion 52 is located in the center of the arrangement direction X. Further, the third flat plate portion 53 is located at the other end in the arrangement direction X. The main surface of each flat plate portion is orthogonal to the arrangement direction X.

Further, the tip of the flat plate portion 54 protrudes in the depth direction of the rope groove 106a rather than the tip of the first flat plate portion 51. Further, the tip of the second flat plate portion 52 protrudes in the depth direction of the rope groove 106 a rather than the tip of the flat plate portion 54. As described above, the distal end of the second flat plate portion 52 protrudes in the depth direction of the rope groove 106a rather than the distal end of the first flat plate portion 51. Thereby, as it goes to the 2nd flat plate part 52 from the 1st flat plate part 51, the space | interval of the front-end | tip of a flat plate part and the bottom part of the rope groove 106a becomes narrow, and the 2nd flat plate located in the center of the arrangement | positioning direction X is carried out. The part 52 is in contact with the bottom of the rope groove 106a. Therefore, it can be said that the interval between the tip of the first flat plate portion 51 and the bottom of the rope groove 106a is wider than the interval between the tip of the second flat plate portion and the bottom of the rope groove 106a. Furthermore, the tip end of the flat plate portion 55 protrudes in the depth direction of the rope groove 106 a rather than the tip end of the third flat plate portion 53. In addition to this, the distal end of the second flat plate portion 52 protrudes in the depth direction of the rope groove 106 a rather than the distal end of the flat plate portion 55. From the above, the tip of the second flat plate portion 52 protrudes in the depth direction of the rope groove 106a rather than the tip of the third flat plate portion 53. Thereby, the space | interval of the front-end | tip of a flat plate part and the bottom part of the rope groove 106a becomes large as it goes to the 3rd flat plate part 53 from the 2nd flat plate part 52. FIG. Therefore, it can be said that the interval between the tip of the third flat plate portion 53 and the bottom of the rope groove 106a is wider than the interval between the tip of the second flat plate portion and the bottom of the rope groove 106a.

As shown in FIG. 8, the width of the flat plate portion in the orthogonal direction Z perpendicular to the arrangement direction X and the depth direction of the groove becomes wider from the first flat plate portion 51 toward the second flat plate portion 52. Accordingly, it can be said that the width d1 of the first flat plate portion 51 is narrower than the width d2 of the second flat plate portion 52. Further, the width of the flat plate portion in the orthogonal direction Z becomes narrower from the second flat plate portion 52 toward the third flat plate portion 53. That is, it can be said that the width of the third flat plate portion 53 is narrower than the width d2 of the second flat plate portion.

Further, as shown in FIG. 9, the first flat plate portion 51, the second flat plate portion 52, the third flat plate portion 53, the flat plate portion 54, and the flat plate portion 55 are arranged on the side surfaces that are parallel to the arrangement direction X. A rectangular parallelepiped fine unevenness is provided.

As shown in FIG. 7, the spacing member 60 is provided between the flat plate portions. The spacing member 60 has a rectangular parallelepiped shape and is a resin member made of PPS or the like. Here, the width of the spacing member 60 in the orthogonal direction Z is smaller than the width of each flat plate portion. As a result, the first flat plate portion 51
And a recessed part will be provided between the flat plate part 54 adjacent to this. Since the spacing member 60 is also present between the other flat plate portions, a concave portion is similarly provided between the flat plate portions.

As shown in FIG. 7, the pin 70 and the nut 72 are provided between the first flat plate portion 51, the flat plate portion 54, the second flat plate portion 52, the flat plate portion 55, the third flat plate portion 53, and each flat plate portion. The spacing member 60 is sandwiched from both sides in the arrangement direction X, and these members are fixed. In order to cope with this, a hole for passing the pin 70 is formed in each flat plate portion and the spacing member 60.

As shown in FIG. 10, the pin 70 is a bolt having a thread portion in which a thread is formed only at the tip portion. Then, the flat plate portion and the spacing member 60 are alternately fitted into the cylindrical portion of the pin 70 having no thread, such as the spacing member 60, the first flat plate portion 51, the spacing member 60, the flat plate portion 54, and the spacing member 60. The flat plate portion and the spacing member 60 are fixed by fastening the nut 72 to the screw portion. Here, on the cylindrical portion of the pin 70, in order to prevent each flat plate portion and the spacing member 60 from moving in the orthogonal direction Z, a rectangular parallelepiped protrusion extending in the arrangement direction X, a so-called key is provided. Therefore, the holes formed in each flat plate portion and the spacing member 60 are also in a shape corresponding to the cylindrical portion of the pin 70.

As described above, in the elevator hoisting machine sheave cleaning tool 10A configured as described above, the durability of the cleaning claws can be increased. Specifically, for example, in the first cleaning claw 42a of the sheave cleaning tool 10 of the elevator hoisting machine that is the first embodiment, the leash groove 106a is cleaned with one rectangular parallelepiped member. In this case, dirt such as lubricating oil fixed to the rope groove 106a is scraped at a time, and a large stress is applied to the first cleaning claw 42a. As a result, if the first cleaning claw 42a is continuously used, deformation is likely to occur, and therefore the first cleaning claw 42a needs to be frequently replaced. On the other hand, as shown in FIG. 11, in the first cleaning claw 42a according to the second embodiment, the sheave 101 is rotated from one side in the arrangement direction X to the other side (right rotation on the paper surface of FIG. 11). Then, the first flat plate portion 51 having the widest distance from the bottom portion of the rope groove 106a first scrapes out the upper layer portion of the dirt 200 such as lubricating oil fixed to the bottom portion of the rope groove 106a. Next, the flat plate portion 54 having the widest gap from the bottom portion of the rope groove 106a after the first flat plate portion 51 scrapes out the middle layer portion of the dirt 200 fixed to the bottom portion of the rope groove 106a. Then, the second flat plate portion 52 that is in contact with the bottom portion of the rope groove 106a scrapes out the lower layer portion of the dirt 200 fixed to the bottom portion of the rope groove 106a. As described above, in the first cleaning claw 42a according to the sheave cleaning tool 10A of the elevator hoisting machine, the dirt 200 fixed to the rope groove 106a is gradually scraped out by the three flat plates. As a result, the stress applied to the first cleaning claw 42a at one time is relaxed and deformation is less likely to occur. As a result, the durability of the cleaning claw can be increased in the sheave gear cleaning tool 10A of the elevator hoisting machine.

Further, in the sheave cleaning tool 10A for the elevator hoisting machine, the distance between the tip of the flat plate portion and the bottom portion of the leash groove 106a becomes wider from the second flat plate portion 52 toward the third flat plate portion 53. Yes. Thus, in the first cleaning claw 42a according to the second embodiment, if the sheave 101 is rotated from the other side in the arrangement direction X to the one side (left rotation on the paper surface of FIG. 11), the rope groove 106a From the third flat plate portion 53 having the widest distance to the bottom of the flat plate portion 55 and the second flat plate portion 52, the dirt adhered to the bottom portion of the rope groove 106a is gradually scraped out. Therefore, the stress applied to the first cleaning claw 42a is relieved, and in the sheave cleaning tool 10A for the elevator hoisting machine, even if the sheave 101 rotates from the other side in the arrangement direction X to the one side, the cleaning claw Durability can be increased. As described above, in the sheave cleaning tool 10 A of the elevator hoist, the durability of the cleaning claws can be improved regardless of which direction the sheave 101 rotates.

Furthermore, in the sheave cleaning tool 10A for an elevator hoist, the width of the flat plate portion becomes wider from the first flat plate portion 51 toward the second flat plate portion 52. Accordingly, as shown in FIG. 12, the distance between the side surface of the rope groove 106 a and the flat plate portion becomes narrower from the first flat plate portion 51 toward the second flat plate portion 52. As a result, in the first cleaning claw 42a of the sheave cleaning tool 10A of the elevator hoisting machine, when the sheave 101 rotates from one side to the other side in the arrangement direction X, the distance from the side surface of the sheave groove 106a. The dirt fixed to the side surface of the rope groove 106a is gradually scraped from the upper layer portion in the order of the flat plate portion 54 and the second flat plate portion 52 from the widest first flat plate portion 51. Thereby, the stress added to the 1st cleaning nail | claw 42a is relieve | moderated and the durability of a cleaning nail | claw can further be improved in the cleaning tool 10A for sheaves of an elevator hoisting machine. In addition, the width of the flat plate portion becomes wider from the third flat plate portion 53 toward the second flat plate portion 52. In other words, the distance between the side surface of the tightrope 106 a and the flat plate portion becomes narrower from the third flat plate portion 53 toward the second flat plate portion 52. Thereby, when the sheave 101 is rotated from the other side in the arrangement direction X to the one side, the flat plate portion 55 and the second flat plate portion are separated from the third flat plate portion 53 having the widest distance from the side surface of the rope groove 106a. In the order of 52, the dirt fixed to the side surface of the rope groove 106a is gradually scraped from the upper layer portion. Therefore, even when the sheave 101 rotates from the other side in the arrangement direction X to the one side, the stress applied to the first cleaning claw 42a is relieved, and the sheave 101 in the sheave cleaning tool 10A of the elevator hoisting machine is relieved. Even if it rotates from the other side of the arrangement direction X to one side, the durability of the cleaning claw can be further enhanced.

Also, as described above, in the sheave cleaning tool 10A of the elevator hoisting machine, the stress applied to the first cleaning claw 42a is relieved and deformation is less likely to occur. Thereby, the 1st cleaning claw 42a will contact | abut firmly to the leash groove 106a, As a result, the stain | pollution | contamination of a leash groove can be removed more reliably.

In the sheave cleaning tool 10A for the elevator hoisting machine, the side surfaces of the first flat plate portion 51, the second flat plate portion 52, the third flat plate portion 53, the flat plate portion 54, and the flat plate portion 55 are finely arranged. Concavities and convexities are provided. Therefore, when the sheave 101 is cleaned, the unevenness scratches the surface of the dirt fixed to the rope groove 106a. As a result, the dirt becomes soft, so that the subsequent flat plate portion easily scrapes the dirt. As a result, in the sheave cleaning tool 10A of the elevator hoisting machine, the dirt in the rope groove 106a can be more reliably removed.

By the way, the spacing member 60 is located between the flat plate portions, and as a result, a concave portion is provided between the flat plate portions. Thereby, when the sheave 101 is cleaned, the dirt scraped out from the rope groove 106a is held in the recess. In this way, the dirt scraped from the rope groove 106a is held between the flat plate portions, and thus the scraped dirt is prevented from reattaching to the rope groove 106a. In the above description, the first cleaning claw 42a and the rope groove 106a are given as examples, but the same applies to the second cleaning claw 42b, the rope groove 106b, the other cleaning claws 42, and the other rope grooves. I can say.

Further, in the sheave cleaning tool 10 A of the elevator hoisting machine, each flat plate portion is a separate member, and these are fixed by a pin 70 and a nut 72. Thereby, for example, when the wear of the first flat plate portion 51 progresses, only the first flat plate portion 51 needs to be replaced, and no other flat plate portion needs to be replaced.

Other configurations of the sheave cleaning tool 10A for the elevator hoisting machine are the same as the sheave cleaning tool 10 for the elevator hoisting machine. Therefore, the other structure of the elevator hoisting machine sheave cleaning tool 10A is as described in the elevator hoisting machine sheave cleaning tool 10A.
