Description

[Technical Field]

[0001] The present invention relates to a device for removing grease adhering to a wire rope for hoisting a water gate and applying new grease. [Background technology]

[0002] Currently, the grease on the wire ropes used to hoist the gate body at the bottom of the operating bridge of roller gates and radial gates can only be applied within reach, and there is concern that deterioration of the grease will reduce the rust prevention effect, leading to further deterioration such as rust on the wires. Therefore, it is necessary to remove the deteriorated grease and then reapply grease. A known technology for removing deteriorated grease from wire ropes is a rope grease removal device that squeezes off the grease from the outer surface of the rope by running the rope while the rope is in a crimped state against a removal hole (see Patent Document 1). However, the grease removal device in Patent Document 1 only squeezes off the grease by running the rope while the device is fixed, and does not have a mechanism for collecting the removed deteriorated grease, so there is a problem in that it is not possible to remove the deteriorated grease by moving the device while the rope is fixed.

[0003] There is also known a cleaning device that sprays a cleaning liquid onto a wire rope to remove the coating of deteriorated grease (see, for example, Patent Document 2). This cleans the existing grease all the way to the inside of the wire strands. There are also cleaning devices that have a wide range of functions, such as wire diameter measurement and camera observation. However, these cleaning devices require large-scale auxiliary equipment such as generators, which take up space, and are also expensive, making them costly and preventing them from becoming widespread.

[0004] Meanwhile, a known technology for reapplying grease to wire ropes is a grease applicator equipped with a brush seal that seals around the wire rope (see Patent Document 3). This is said to prevent grease from leaking from around the wire rope. However, the grease applicator of Patent Document 3 has a problem in that the linear members that make up the brush seal may deform during operation, causing grease to leak out. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Publication No. 49-070237 [Patent Document 2] Japanese Patent Application Laid-Open No. 2007-130594 [Patent Document 3] Japanese Patent Application Laid-Open No. 2004-238762 Summary of the Invention [Problem to be solved by the invention]

[0006] In view of the above circumstances, an object of the present invention is to provide a wire grease removal and application device that can easily and effectively remove and apply wire grease. [Means for solving the problem]

[0007] After extensive research, the inventors discovered that sufficient rust prevention effects can be achieved by frequently removing grease from the wire and applying grease, even if the inside of the wire strands is not cleaned and grease is not applied.

[0008] That is, the wire grease removal and application device of the first aspect of the present invention comprises a scraper unit in which multiple scrapers that scrape off deteriorated grease adhering to the wire rope are arranged around the wire rope rather than being arranged in the same plane, a removal unit that has inside it a deteriorated grease storage section that stores the scraped-off deteriorated grease, and an application unit into which the wire rope is inserted and into which grease to be applied is filled via an introduction tube. In the removal unit, multiple scrapers are installed on the same plane, creating gaps between the scrapers and ensuring a flow path for collecting the deteriorated grease scraped off by the scrapers. This prevents the deteriorated grease from accumulating on the scrapers, improving the removal and collection performance of the deteriorated grease. By providing a deteriorated grease storage section inside the removal unit, it is possible to simultaneously remove and collect deteriorated grease adhering to the surface of the wire rope. The term "deteriorated grease" refers to the grease to be removed, and does not limit the degree of deterioration. The grease to be applied is biodegradable, and will not cause any environmental problems even if it falls into a river. In order to improve the quality of each operation of removing deteriorated grease and applying grease, it is preferable that the removal unit and the application unit can be used separately, so it is preferable that the removal unit and the application unit are provided separately, but they may also be detachably connected, for example, in the axial direction of the wire rope.

[0009] In the wire grease removing and applying device according to the first aspect of the present invention, each scraper in the scraper unit preferably includes a scraping portion that scrapes off grease adhering to the wire rope, a biasing member that applies a biasing force to the scraping portion against the wire rope, and a holding member that is fixed to the inner wall of the removing unit and holds the scraping portion attached via the biasing member. With this configuration, the scraping portion can be abutted according to the size and shape of the wire rope, thereby improving the performance of removing deteriorated grease.

[0010] In the wire grease removal and application device of the first aspect of the present invention, the contact portion of the scraping unit against the wire rope preferably has a partial elliptical shape, the pair of scrapers are arranged opposite each other across the wire rope and intersect with each other at the wire rope, and the contact portion of the pair of scrapers preferably has a circular shape surrounding the wire rope as viewed in the axial direction of the wire rope. By arranging the pair of scrapers so that they intersect, a flow path for collecting deteriorated grease can be provided between the scrapers in a compact shape. As a result, it is possible to effectively prevent deteriorated grease from accumulating on the scrapers, making it easier to collect the deteriorated grease. Furthermore, by making the contact portion of the scraper not polygonal but circular in shape so as to surround the wire rope when viewed in the axial direction of the wire rope, it is possible to prevent the scraper from getting caught on the wire rope when the device is slid. Note that the partial elliptical shape here refers to a shape in which the longitudinal direction of the ellipse is arranged up and down, and as a result, the contact portion has a circular shape so as to surround the wire rope when viewed in the axial direction of the wire rope.

[0011] In the wire grease removing and applying device of the first aspect of the present invention, the pair of scrapers may be arranged at different heights, and the abutting portion of the pair of scrapers may be circular and surround the periphery of the wire rope as viewed in the axial direction of the wire rope. By arranging the pair of scrapers at different heights, a flow path for collecting deteriorated grease can be provided between the scrapers. Note that the pair of scrapers may also be arranged so as to intersect and at different heights.

[0012] In the wire grease removing and applying device according to the first aspect of the present invention, it is preferable that the scraping portion of the scraper is divided into at least two portions, each of which is provided with a biasing member, and each of which is independently attached to the holding member. By dividing the scraping portion and providing the biasing member, the ability to conform to the shape of the target wire rope is improved.

[0013] In the wire grease removing and applying device of the first aspect of the present invention, the removing unit may be provided with an upper end holding part having an upper valve extending into the interior space at the upper end of the unit body, and a lower end holding part having a lower valve extending into the interior space at the lower end of the unit body. By providing the upper end holding part and the lower end holding part, it is possible to effectively prevent the recovered deteriorated grease from leaking to the outside, and also to stably hold the wire rope.

[0014] The wire grease removal and application device of the first aspect of the present invention may further include a second removal unit having a groove cleaning unit including a groove cleaning member provided around the wire rope with the tips of rod-shaped scraping members corresponding to the number of strands abutting the grooves and disposed around the wire rope to scrape off degraded grease adhering to the grooves, and support members disposed above and below the groove cleaning member, and a degraded grease storage unit for storing the scraped-off degraded grease. By using a removal unit capable of selectively removing degraded grease adhering to the outer peripheral surface of the wire rope in combination with a second removal unit having the function of removing degraded grease adhering to the grooves of the wire rope, degraded grease can be removed more effectively. These two types of removal units may also be integrated into one removal unit.

[0015] A wire grease removal and application device according to a second aspect of the present invention includes a groove cleaning unit including a groove cleaning member disposed around the wire rope with the tips of rod-shaped scraping members corresponding to the number of strands contacting the grooves and scraping off deteriorated grease adhering to the grooves between the strands of the wire rope, and support members disposed above and below the groove cleaning member, and a deteriorated grease storage section for storing the scraped-off deteriorated grease, and an application unit into which grease to be applied is filled via an introduction tube and into which the wire rope is inserted. With this configuration, it is possible to remove deteriorated grease adhering to the grooves of the wire rope and then apply new grease.

[0016] In the wire grease removal and application device according to the first or second aspect of the present invention, the application unit is divided into two units in the wire rope insertion direction, and each unit is connected by a hinge portion so as to be freely opened and closed. The application unit has a cylindrical application unit main body that is open at the top and bottom when closed, and a clamping portion consisting of a pair of clamping members is provided at the top and bottom of the application unit main body. The clamping portion preferably has a concave-convex portion provided on the end of one of the clamping members that fits into a concave-convex portion provided on the end of the other clamping member to prevent leakage of the applied grease. By providing the concave-convex portion on the end of the clamping member, leakage of the applied grease can be effectively prevented. To enhance the ability to prevent leakage of the applied grease, each clamping member is preferably provided with a biasing member.

[0017] The wire grease removal and application device of the first or second aspect of the present invention may be configured such that a grease intake section extending downward in a trumpet shape is provided at the lower end of the application unit, and the application unit slides downward along the wire rope after the grease has been applied, thereby taking in excess grease on the wire rope without dropping. With the pressure pump operating, the applicator unit is slid upward to apply grease to the wire rope. Then, the pressure pump is stopped and the applicator unit is slid downward. This allows excess grease from the applied grease to be drawn into the applicator unit. Specifically, the excess grease is drawn into the gap between the applicator unit and the valley portion of the wire rope. If the grease intake portion were not horn-shaped but had a uniform diameter, there would be a problem in that the grease would accumulate outside the applicator unit and fall downward. Therefore, by providing a horn-shaped grease intake portion extending downward, the excess applied grease can be effectively drawn into the applicator unit without falling when the applicator unit is lowered. [Effects of the Invention]

[0018] The wire grease removal and application device of the present invention has the effect of being able to easily and effectively remove and apply wire grease. [Brief explanation of the drawings]

[0020] An example of an embodiment of the present invention will be described in detail below with reference to the drawings. Note that the scope of the present invention is not limited to the following examples and illustrated examples, and many modifications and variations are possible. [Example]

[0021] FIG. 17 shows a usage flow diagram of the wire grease removal and application device of Example 1. The wire grease removal and application device of Example 1 is composed of a removal unit 1 and an application unit 2. As shown in FIG. 17, the order of use of each unit is as follows: first, the removal unit 1 is used to remove deteriorated grease on the wire (step S01), and then the application unit 2 is used to apply grease to be applied (step S02). Here, the removal unit 1 and the application unit 2 that constitute the wire grease removal and application device of Example 1 will be described.

[0022] 1 shows a front view of the removal unit of Example 1. As shown in FIG. 1, the removal unit 1 is composed of a removal unit main body 11, a scraper unit 3, an upper end holding part 12, and a lower end holding part 13. The scraper unit 3 is comprised of a pair of scrapers (31, 32) disposed at opposing positions crossing each other in the short direction of the removal unit body 11, and is disposed on the inner surface of the removal unit body 11. The scrapers (31, 32) scrape off deteriorated grease adhering to the wire rope. An upper end holding portion 12 is disposed at the upper end of the removal unit body 11, and a lower end holding portion 13 is disposed at the lower end of the removal unit body 11. The removal unit 1 is provided with locking portions (16a to 16d) to which a rope or the like can be fastened and pulled from above or below, thereby allowing the removal unit 1 to slide on the wire rope 9.

[0023] FIG. 2 shows the removal unit of the first embodiment in an open state. As shown in FIG. The removal unit body 11 is divided into two in the longitudinal direction, a removal unit body 11a and a removal unit body 11b, and the removal unit bodies (11a, 11b) are connected so as to be able to open and close freely by a hinge part 15. When closed, the removal unit bodies are open at the top and bottom and have a cylindrical shape with a deteriorated grease storage part 110 inside. The deteriorated grease storage part 110 stores the deteriorated grease that has been scraped off. Scraper 31 is provided on the inner surface of removal unit body 11a, and scraper 32 is provided on the inner surface of removal unit body 11b. As shown in Fig. 2, when removal unit body 11 is open, the scrapers (31, 32) are both arranged diagonally at an angle of approximately 45° from the upper right to the lower left. Therefore, when removal unit body 11 is closed, the scrapers (31, 32) are arranged to intersect as shown in Fig. 1.

[0024] The upper end holding portion 12 is divided into two longitudinally, upper end holding portion 12a and upper end holding portion 12b, and the lower end holding portion 13 is divided into two longitudinally, lower end holding portion 13a and lower end holding portion 13b. The upper end holding portion 12a is provided at the upper end of the removal unit main body 11a, and the lower end holding portion 13a is provided at the lower end of the removal unit main body 11a. Similarly, the upper end holding portion 12b is provided at the upper end of the removal unit main body 11b, and the lower end holding portion 13b is provided at the lower end of the removal unit main body 11b. The upper end holding portions (12a, 12b) are equipped with upper valves 120 extending toward the interior space, and the lower end holding portions 13 (13a, 13b) are equipped with lower valves 130 extending toward the interior space. The removal unit 1 inserts the wire rope 9 inside the scraper unit 3 and slides it on the wire rope 9 to remove the deteriorated grease on the wire rope 9 and collect it in the deteriorated grease storage section 110.

[0025] 3A and 3B are explanatory diagrams of the structure of the scraper unit of the first embodiment, in which (1) is a plan view, (2) is a left side view of the scraper 31 when (1) is viewed as the front, and (3) is a right side view of the scraper 32 when (1) is viewed as the front. As shown in FIGS. 3A and 3B, the scraper 31 is composed of holding members (311, 312), scraping portions (33a, 33b), and a spring 34. The scraping portions (33a, 33b) scrape out grease adhering to the wire rope 9, and guide holes 35 are formed in the scraping portions (33a, 33b) to which the spring 34 is attached. The spring 34 is a biasing member that applies a biasing force to the scraping portions (33a, 33b). The holding members (311, 312) are fixed to the inner space of the removal unit main body 11 and hold the scraper 31 attached via a spring 34, and either the holding member 311 or the holding member 312 has a protrusion 36. The scraping portions (33a, 33b) are attached with springs 34, and are sandwiched between the holding members (311, 312) with the protrusions 36 fitted in the guide holes 35.

[0026] 3(1) and 3(3), similar to the scraper 31, the scraper 32 is composed of holding members (321, 322), scraping portions (33c, 33c), and a spring 34. A guide hole 35 is formed in the scraping portions (33c, 33d), and a protrusion 36 is provided on either the holding member 321 or the holding member 322. The scraping portions (33c, 33d) are clamped between the holding members (321, 322) with the spring 34 attached and the protrusion 36 fitted in the guide hole 35. In this way, by providing the springs 34 and fixing the scraping portions (33a to 33d), the contact portions with the wire rope 9 can be made elastic, and deteriorated grease can be effectively scraped off.

[0027] 4 and 5 are explanatory diagrams of the scraper of Example 1. When the scrapers (31, 32) are viewed from directions B and C in FIG. 4, the contact portions of the scraping portions (33a to 33d) with the wire rope 9 have an elliptical shape as shown in FIG. 5(1). However, when the scrapers (31, 32) are viewed from direction A in FIG. 4, the contact portions of the scraping portions (33a to 33d) with the wire rope 9 have a substantially circular shape as shown in FIG. 5(2). In this way, the scraping portions (33a to 33d) are provided so that the contact portions with the wire rope 9 have a substantially circular shape when the scrapers (31, 32) are disposed at an angle.

[0028] FIG. 6 shows an image of the scraper and wire abutting against each other. A more common way to twist a wire rope is to twist it counterclockwise, as in the case of wire rope 9 shown in FIG. 6, rather than twisting it clockwise, as in the case of S-twisting. If the scrapers (31, 32) were arranged in the same direction as the twist of the wire rope 9, there is a risk that the scrapers (31, 32) would get caught in grooves 92 formed between adjacent strands 91 during operation of the removal unit. Therefore, as shown by dashed lines D and E in FIG. 6, the scrapers (31, 32) are arranged so as not to be in the same direction as the twist of the strands 9, in other words, so that the longitudinal direction of the scrapers (31, 32) is approximately perpendicular to the strands 91, thereby enabling smooth removal of deteriorated grease.

[0029] Here, the procedure for using the removal unit will be described. First, as shown in Figure 2, the removal unit 1 is opened and the wire rope 9 is placed. Next, the removal unit 1 is closed and fixed using the fastener 14 shown in Figure 1. 7 and 8 show conceptual diagrams of the removal unit of the first embodiment in use. In FIG. 7, a wire rope 9 is inserted through the removal unit 1. Furthermore, a rope 7a is fastened to the locking portion 16a, and a rope 7b is fastened to the locking portion 16b. Pulling the wire rope 9 upward allows the wire rope 9 to slide upward. Similarly, a rope 7c is fastened to the locking portion 16c, and a rope 7d is fastened to the locking portion 16d. Pulling the wire rope 9 downward allows the wire rope 9 to slide downward. In FIG. 7, the removal unit 1 is slid upward using the ropes (7a, 7b) to remove deteriorated grease 81 adhering to the wire rope 9. Alternatively, as shown in FIG. 8, the removal unit 1 may be slid up and down using the ropes (7a, 7b) or the ropes (7c, 7d). Alternating up and down sliding allows the deteriorated grease 81 adhering to the wire rope 9 to be more effectively removed.

[0030] Next, we will explain how to collect the deteriorated grease 81 removed from the wire rope 9. When the removal unit 1 is slid downward to remove the deteriorated grease 81, the deteriorated grease 81 accumulates on the lower surface of the scrapers (31, 32). Therefore, when a certain amount of the scraped-off deteriorated grease 81 accumulates on the lower surface of the scrapers (31, 32), it naturally falls off the scrapers (31, 32) due to gravity and is collected in the deteriorated grease storage section 110. In contrast, when the removal unit 1 is slid upward to remove the degraded grease 81, the degraded grease 81 accumulates on the upper surfaces of the scrapers (31, 32), and if the scrapers (31, 32) were arranged horizontally and at approximately the same height, the scraped-off degraded grease 81 would not fall downward but would continue to accumulate on the upper surfaces of the scrapers (31, 32). As a result, if the removal unit 1 continues to slide upward, the areas below the scrapers (31, 32) would have difficulty functioning as a storage area, and the degraded grease 81 would be more likely to overflow from the upper end holding portion 12.

[0031] In contrast, the removal unit 1 of Example 1 is configured so that the area below the scrapers (31, 32) fully functions as a storage area even when the removal unit 1 continues to slide upward. Figures 9 and 10 are conceptual diagrams illustrating the recovery of deteriorated grease. These diagrams illustrate the relationship between the deteriorated grease storage area 110 and the scrapers (31, 32) when the deteriorated grease 81 is scraped off by the scrapers (31, 32) as the removal unit 1 slides upward, as shown in Figure 7. In the diagrams, the solid lines indicate the front side, and the dashed lines indicate the rear side. 9 or 10, the scrapers (31, 32) are arranged to intersect in the removal unit body 11, and therefore a gap is formed between the front side of the scraper 31 and the rear side of the scraper 32 and the inner surface of the removal unit body 11. Therefore, the deteriorated grease (81a, 81b) scraped off by the scrapers (31, 32) passes through the gap and falls downward.

[0032] 9, by sliding the removal unit 1 upward, the degraded grease 81a is scraped off by the scraper 31, and the degraded grease 81b is scraped off by the scraper 32. Then, the scraped-off degraded grease 81a slides down from the upper right rear side to the lower left rear side due to gravity, then falls to the lower left front side, and is collected in the degraded grease storage unit 110. Similarly, the scraped-off degraded grease 81b slides down from the upper left front side to the lower right front side due to gravity, then falls to the lower right rear side, and is collected in the degraded grease storage unit 110.

[0033] Furthermore, not all of the removed deteriorated grease (81a, 81b) necessarily slides downward, and some of the removed deteriorated grease (81a, 81b) may overflow above the scrapers (31, 32). For example, as shown in FIG. 10 , when some of the deteriorated grease 81a scraped off by the scraper 31 overflows upward, it falls from the upper right rear side (scraper 31) to the lower right front side (scraper 32), then falls further to the lower right rear side, and is collected in the deteriorated grease storage unit 110. Similarly, when some of the scraped off deteriorated grease 81b overflows upward, it falls from the upper left front side (scraper 32) to the lower left rear side (scraper 31), then falls further to the lower right front side, and is collected in the deteriorated grease storage unit 110. In this way, by arranging the surfaces of the scrapers (31, 32) so that they are not flush, a gap is formed between the scrapers 31 and 32 that serves as a flow path for the deteriorated grease (81a, 81b), thereby improving the storage capacity of the deteriorated grease storage section 110.

[0034] Next, the coating unit 2 will be described. Fig. 11 is a front view of the coating unit of Example 1, Fig. 12 is a structural explanatory diagram of the coating unit of Example 1, and Fig. 13 is a plan view of the coating unit of Example 1. For ease of explanation, fasteners 14a are not shown in Fig. 12. 11, the application unit 2 is composed of an application unit main body 21, a cover member 22, a grease inlet portion 23, and an introduction tube 28. The cover member 22 is provided at the upper end of the application unit main body 21, and the grease inlet portion 23 is provided at the lower end of the application unit main body 21. One end of the introduction tube 28 is connected to the application unit main body 21, and the other end is connected to a grease supply device (not shown), so that the application grease can be supplied into the application unit main body 21.

[0035] As shown in Figure 12, the application unit main body 21 has an application grease storage section 210 into which application grease 82 can be filled through an introduction tube 28, and the wire rope 9 is inserted into the application grease storage section 210 and slid over the wire rope 9 to apply application grease 82 onto the wire rope 9. As shown in FIG. 11, the application unit main body 21 is divided into two application unit main bodies (21a, 21b) in the longitudinal direction. These are connected by a hinge portion 15a shown in FIG. 13 so as to be freely opened and closed, and are secured in place using a fastener 14a. When the application unit main bodies (21a, 21b) are closed, the application unit main body 21 has a cylindrical shape with open top and bottom. Just as the application unit main body 21 is divided into two application unit main bodies (21a, 21b), the cover member 22 or the grease inlet portion 23 is also divided into two. That is, as shown in FIG. 11, the application unit main body 21a has a cover member 22a at its upper end and a grease inlet portion 23a at its lower end, and the application unit main body 21b has a cover member 22b at its upper end and a grease inlet portion 23b at its lower end. The cover member 22 is intended to prevent the grease to be applied from leaking from the upper end of the application unit main body 21. The grease draw-in section 23 allows the application unit 2 to slide downward on the wire rope 9 after grease application with the pressure pump stopped, thereby allowing excess applied grease 82 to be taken into the application unit 2 without dropping.

[0036] As shown in Fig. 12, a clamping section 4 consisting of a pair of clamping members (4a, 4b) is provided at the top and bottom of the application unit main body 21. Fig. 14 is an explanatory diagram of the clamping members, where (1) is a front view, (2) is a right side view, and (3) is a plan view. Here, the clamping member 4b will be described as an example, but the clamping member 4a has a similar structure. As shown in FIGS. 14(1) to (3), two springs 24 are attached as biasing members to holes 24a provided in the clamping member 4b. As shown in FIG. 14(3), two guide holes 25 are provided, and the guide holes 25 are attached so as to fit into the protrusions 29 provided on the application unit main body 21b shown in FIG. 13. 14(1) or 14(3), two pairs of recesses 26 and protrusions 27 are provided on the clamping member 4b, and the recesses 26 of the clamping member 4b are arranged in combination so as to abut against the protrusions 27 of the clamping member 4a, and the protrusions 27 of the clamping member 4b are arranged in combination so as to abut against the recesses 26 of the clamping member 4a. As a result, the recesses and protrusions provided on the end of the clamping member 4a fit together with the recesses and protrusions provided on the end of the clamping member 4b, preventing leakage of the applied grease 82.

[0037] 15 and 16 show conceptual diagrams of the application unit of Example 1 in use. As shown in FIG. 15, a wire rope 9 is inserted through application unit 2. Rope 7e is fastened to locking portion 16e, and rope 7f is fastened to locking portion 16f, so that the application unit can be slid upward by pulling it up from above. Similarly, rope 7g is fastened to locking portion 16g, and rope 7h is fastened to locking portion 16h, so that the application unit can be slid downward by pulling it down from below. 15 shows an image of applying grease 82 to the wire rope 9 by sliding the application unit 2 upward using the ropes (7e, 7f). Alternatively, as shown in FIG. 16, the application unit 2 may be slid up and down using the ropes (7e, 7f) or ropes (7g, 7h). By sliding the application unit 2 alternately up and down, the application grease 82 can be applied to the wire rope 9 more effectively.

[0038] In addition, a grease intake section 23 with a trumpet-shaped opening is provided at the lower end of the application unit main body 21, so that after the application unit main body 21 is slid upward while the pressure pump is operating to apply grease onto the wire rope 9, the application unit 2 can be slid downward with the pressure pump stopped, and excess grease from the applied application grease 82 can be taken into the application unit 2 through the gap between the clamping section 4 and the groove section 92 of the wire rope 9. [Example]

[0039] In the following Examples 2 to 6, examples in which the arrangement and number of scrapers are changed will be described with reference to Figures 18 to 23. For ease of explanation, Figures 18 to 23 only show the removal unit main body 11, the scrapers (31, 31a, 31b, 32, 32a, 32b), and the wire rope 9. In the figures, the scrapers (31, 31a, 31b, 32, 32a, 32b) are shown with the side where the scraping portion 33 is provided in black, and the holding members and the like in white.

[0040] FIG. 18 is an explanatory diagram of a removal unit of Example 2. As shown in FIG. 18, the removal unit 1a of Example 2 differs from the removal unit 1 of Example 1 in that two scraper units 3 are provided in the removal unit main body 11. Similar to Example 1, each scraper unit 3 is made up of scrapers (31, 32) and is arranged in opposing and intersecting positions. By providing two scraper units 3, one above the other, it is possible to prevent the removal unit main body 11 from tilting relative to the wire rope 9 during operation, and it is possible to remove the deteriorated grease 81 smoothly and effectively. [Example]

[0041] FIG. 19 is an explanatory diagram of the removal unit of Example 3, where (1) is a right side view and (2) is a front view. FIG. 20 shows an image of the removal of deteriorated grease in Example 3. As shown in FIG. 19(1) or (2), the scraper unit 300 of the removal unit 1b of Example 3 differs from the scraper unit 3 of the removal unit 1 of Example 1 in that the scrapers (31a, 32a) are horizontally disposed and positioned at different heights. Therefore, as shown in FIG. 20, in the removal unit 1b, when the removal unit 1b is pulled upward, the deteriorated grease 81 accumulated on the upper surface of the upper scraper 31a falls onto the upper surface of the lower scraper 32a, and then falls below the scraper 31a together with the deteriorated grease 81 accumulated on the upper surface of the scraper 32a. In this way, the removal unit 1b is able to effectively collect the removed deteriorated grease 81 by changing the position of the scraper up and down, rather than by changing the angle at which the scraper is installed. [Example]

[0042] 21 is an explanatory diagram of a removal unit of Example 4, where (1) is a right side view and (2) is a front view. As shown in FIG. 21, the removal unit 1c of Example 4 has two scraper units 300, one above the other, similar to the removal unit 1b of Example 3. This prevents the removal unit body 11 from tilting relative to the wire rope 9 during operation, making it possible to remove deteriorated grease 81 smoothly and effectively. [Example]

[0043] 22 is an explanatory diagram of a removal unit of Example 5, where (1) is a right side view and (2) is a front view. As shown in FIG. 22, removal unit 1d of Example 5 has two horizontal scraper units arranged one above the other, similar to removal unit 1c of Example 4. However, unlike removal unit 1c, the lower scraper unit 301 has scraper 32a arranged on the upper level and scraper 31a arranged on the lower level. In this way, by changing the scraper arrangement for each scraper unit, it is possible to prevent the removal unit from tilting relative to the wire rope 9 during operation, which would result in a reduction in removal performance. [Example]

[0044] Fig. 23 shows a right side view of the removal unit of Example 5. As shown in Fig. 23, the removal unit 1e of Example 5 includes a scraper unit consisting of a pair of scrapers, similar to the removal unit 1 of Example 1. However, unlike the removal unit 1 of Example 1, the scrapers (31b, 32b) in the scraper unit 3b are arranged at positions of different heights. By arranging the scrapers (31b, 32b) at different heights in this manner, a larger flow path for the removed deteriorated grease 81 can be provided, thereby improving grease recovery performance. [Example]

[0045] The removal unit of Example 7 comprises a groove cleaning member that scrapes off deteriorated grease adhering to grooves formed between strands of the wire rope, and is provided around the wire rope with the tips of rod-shaped scraping parts, the number of which is the same as the number of strands, in contact with the grooves; a groove cleaning unit that comprises support members provided above and below the groove cleaning member; and a deteriorated grease storage section that stores the scraped-off deteriorated grease. The second removal unit has both the above and the above in it. FIG. 24 is an explanatory diagram of the removal unit of Example 7, showing a cross-sectional image from the front. As shown in FIG. 24, in the removal unit 1f of Example 7, a groove cleaning unit 37 is provided inside the removal unit main body 17. The removal unit main body 17 is provided with locking portions (16a to 16d), to which ropes (7a to 7d) are respectively fastened. Although not shown, the upper end of the removal unit main body 17 is provided with an upper end holding portion 12, and the lower end of the removal unit main body 17 is provided with a lower end holding portion 13, similar to the removal unit 1 of Example 1. Although not shown, the opening and closing mechanism is also the same as the removal unit 1 of Example 1, in that the removal unit main body 17 is structured to be divided into two in the longitudinal direction, and the two are connected to each other by a hinge portion 15 so as to be freely opened and closed, and has a mechanism for fastening the two portions using a fastener 14.

[0046] The space inside the removal unit body 17 serves as a deteriorated grease storage section 110 a, which stores the deteriorated grease scraped off by the groove cleaning unit 37 . The groove cleaning unit 37 is composed of a groove cleaning member 38 and support members (39a, 39b) provided above and below the groove cleaning member 38. The support members (39a, 39b) are each fixed inside the removal unit body 17. Gaps (40, 41) are formed between the support members (39a, 39b) and the wire rope 9. This allows the unit to accommodate wire ropes 9 of various sizes and also enables scraped-off deteriorated grease to fall downward. The wire rope 9 itself is held by an upper end holding portion 12 and a lower end holding portion 13. The groove cleaning member 38 is provided separately from the other members that make up the removal unit 1f.

[0047] FIG. 25 is an explanatory diagram of the groove cleaning member, where (1) is a plan view and (2) is an FF cross-sectional view of (1). As shown in FIG. 25(1), the groove cleaning member 38 is composed of holding portions (381, 382) and rod-shaped scraping portions (330a-330f). As shown in FIG. 25(2), the holding portion 381 is composed of holding members (381a, 381b) and clamps the rod-shaped scraping portions (330a-330c) shown in FIG. 25(1). Similarly, the holding portion 382 is composed of holding members (382a, 382b) and clamps the rod-shaped scraping portions (330d-330f). The holding portions 381 and 382 are structured to be fixed using fasteners (43a, 43b), but one of them may be a hinge mechanism, for example.

[0048] The rod-shaped scraping portions (330a to 330f) are configured so that they can be adjusted by threading a rod-shaped member with a male screw portion into the inside of a cylindrical member with a female screw portion, and the tip portion can be brought into contact with the groove portion 92 of the wire rope 9. In this embodiment, as shown in Figure 25(1), strands (9b to 9g) are spirally arranged around the core 9a of the wire rope 9, and the groove cleaning member 38 is attached so that the rod-shaped scraping portion 330a comes into contact with the groove portion 92 between the strands 9b and 9c. Similarly, groove cleaning members 38 are attached so that rod-shaped scraping portion 330b abuts between strands 9c and 9d, rod-shaped scraping portion 330c abuts between strands 9d and 9e, rod-shaped scraping portion 330d abuts between strands 9e and 9f, rod-shaped scraping portion 330e abuts between strands 9f and 9g, and rod-shaped scraping portion 330f abuts between strands 9g and 9b. The tips of the rod-shaped scraping portions (330a to 330f) are curved so as not to damage the strands (9b to 9g). In this way, by abutting the rod-shaped scraping portion (330a to 330f) against the groove portion 92 of the wire rope 9 and then sliding the removal unit main body 17 up and down, it is possible to effectively remove deteriorated grease adhering to the groove portion 92.

[0049] FIG. 26 shows an image of the use of the removal unit of Example 7. When using the removal unit 1f, as shown in FIG. 26, groove cleaning member 38 is attached to wire rope 9, and then removal unit main body 17 is attached to wire rope 9 so that groove cleaning member 38 is positioned between support members 39a and 39b. Then, the ropes (7a to 7d) tied to the locking portions (16a to 16d) are pulled up and down, and the removal unit 1f is slid up and down to remove deteriorated grease adhering to wire rope 9. In the example shown in FIG. 26, the ropes (7a, 7b) are pulled upward, and the removal unit 1f is slid upward to remove deteriorated grease adhering to grooves 92 of wire rope 9. The groove cleaning member 38 is attached to the wire rope 9 separately from the other components of the removal unit 1f. Therefore, when the removal unit 1f is slid upward, the groove cleaning member 38 moves relatively downward and abuts against the support member 39b. After that, it rotates along the spiral shape of the strand (9b-9g), scraping off the deteriorated grease adhering to the wire rope 9. The abutment surface of the support member 39b with the groove cleaning member 38 is made of a material with a low friction coefficient, so it is structured not to impede the rotation of the groove cleaning member 38. The scraped-off deteriorated grease falls downward through the gap 42 between the holding portion (381, 382) and the rod-shaped scraping portion (330a-330f) shown in Figure 25(1) or (2), then passes through the gap 41 provided in the support member 39b and is collected in the storage portion 110a.

[0050] Next, when the removal unit 1f is slid downward, the groove cleaning member 38 moves relatively upward and abuts against the support member 39a, then rotates along the spiral shape of the strands (9b to 9g), scraping off further deteriorated grease adhering to the wire rope 9 (not shown). The abutting surface of the support member 39a with the groove cleaning member 38 is also made of a material with a low coefficient of friction, so it is structured not to impede the rotation of the groove cleaning member 38. The scraped-off deteriorated grease falls downward through the gap 41 provided in the support member 39b and is collected in the storage section 110a. In this way, the removal unit 1f has the function of removing deteriorated grease adhering to the groove portion 92 of the wire rope 9, and therefore, by using it in conjunction with a removal unit 1 that can selectively remove deteriorated grease adhering to the outer surface of the wire rope 9, deteriorated grease can be removed more effectively.

[0051] (Other Examples) 1) Any one of the scraper units (3, 3b, 300, 301) or three or more of these may be arranged in combination above and below. Also, two scraper units 3b may be arranged in combination above and below. 2) The removal units (1, 1a to 1e) and the removal unit 1f may be integrated into one removal unit. 3) The wire grease removal and application device may be provided with the removal unit 1f and the application unit 2. [Industrial Applicability]

[0052] The present invention is useful as a technology for removing grease adhering to wire ropes for hoisting water gates and applying new grease. [Explanation of symbols]
