2. Description of the Related Art Conventionally, wire ropes for opening and closing dams, river gates, etc. (hereinafter simply referred to as "ropes") have been coated with grease for the purpose of rope protection, rust prevention, lubrication, etc. at regular intervals. It is practiced to remove old grease and re-apply new grease every two to three years, for example.

Conventionally, the work of re-applying grease depends on the manual work of the worker, but there is a problem that the workability is poor and the work is dangerous because of the work at an unstable high place. .

Therefore, recently, a device for substituting a part of this type of work has been proposed. For example, various rope cleaning devices for removing old grease have been developed. As a typical example, a hollow device main body is externally attached to a rope, and while moving this along the rope, a cleaning liquid such as light oil or high-pressure water is sprayed onto the rope from a nozzle provided inside the old equipment. An apparatus has been proposed in which the grease is removed, and the removed grease is led out to the outside of the apparatus main body through a drain pipe together with a used cleaning liquid and the like and is collected (JP-A-6-79242, JP-A-11-11242).

The rope cleaning device as described above has the following problems.

For example, in the repainting work of grease, there is a demand to apply new grease promptly after washing the rope. However, in the above-mentioned conventional apparatus, the washing liquid is likely to remain on the rope after the washing work, and the rope is left to some extent. It is necessary to wait for it to dry before applying new grease. Therefore, it is difficult to meet such a request, and there remains a problem in efficiently performing a series of operations for re-greasing.

Further, in this type of rope cleaning device, if the used cleaning liquid used for cleaning flows into a dam or river, it will lead to water pollution. Therefore, it is necessary to reliably collect the used cleaning liquid without leaking it to the outside. There is.

In this respect, in the conventional apparatus, a sealing member is provided in the rope passage hole to prevent the washing liquid from flowing out. However, since the rope has a structure in which a plurality of strands are twisted, the rope passage hole is not formed. It was difficult to completely seal it, and it was impossible to completely eliminate the leakage of the cleaning liquid. It is also considered that the inside of the main body of the device is sucked to positively suck out the used cleaning liquid, but in order to completely prevent the leakage of the cleaning liquid, a large suction machine with extremely high output is required, Considering the place where repainting work is performed and the cost, it does not follow the actual situation.

Therefore, in the above rope cleaning device, a series of grease repainting operations can be efficiently performed, and the leakage of the cleaning liquid can be surely prevented by the configuration according to the actual situation. However, it is desired to be able to remove the grease satisfactorily.

In addition to the above-described rope washing work, the grease repainting work includes an inspection work of the washing state and a grease application work to the rope. It is convenient if it can be performed continuously with the cleaning work.

The present invention has been made in view of the above problems, and a first object thereof is to enable the cleaning liquid to be quickly removed from the rope, and a second object thereof is to prevent the cleaning liquid from leaking. The third purpose is to reliably perform the inspection work and the grease application work as well as the cleaning of the wire rope.

It is configured to prevent a collision with the device body 10 or the like.

12 to 14 schematically show the structure of the coating apparatus main body 13.

The coating device main body 13 also has a vertically elongated cylindrical shape, like the other two device main bodies 10 and 12 described above. A passage hole 102 for the rope 5 is provided on both upper and lower end surfaces of the coating device main body 13, and flanges 104 for connecting the operation wire 15 of the moving device 14 are provided on the peripheral surfaces of the upper and lower end portions thereof. There is.

The coating apparatus main body 13 is also composed of two unit main bodies 100a and 100b which are divided in the radial direction, like the other apparatus main bodies 10 and 12.

A plurality of corresponding coupling flanges 106, 110 are formed side by side in the vertical direction on each unit main body 100a, 100b, and the flange 106 on one side is formed.
A bolt 107 is projectingly provided on the other side, and a U groove 111 is formed on the other side flange 110. That is, the unit main bodies 100a and 100b are overlapped with the rope 5 sandwiched therebetween, and the bolt 107 of the flange 106 on one side is inserted into the U groove 111.
Through the flange 110 on the other side, and the wing nut 112 is fastened to the bolt 107 from the opposite side of the flange 110 (the right side in FIGS. 12 and 13) to connect the unit bodies 100a and 100b. The applicator body 13 is configured to be fitted onto the outer circumference of the rope 5.

Inside the main body 13 of the coating apparatus, as shown in FIG. 14, an oil reservoir chamber 120 is formed at the center in the vertical direction.
A port 122 is provided on a side wall portion of the oil sump chamber 120, and the refueling machine 69 mounted on the vehicle T and the port 122 are communicatively connected by a refueling pipe 121.

Here, as shown in FIG. 1, a branch pipe 61 that branches from the air supply pipe 60 is connected to the oil supply device 69, and air from the compressor 67 is supplied through the branch pipe 61 to the oil supply device 69. And the grease stored in the tank of the refueling machine 69 is pressure-fed by the air pressure. The air supply pipe 60 and the branch pipe 61 are provided with open / close valves 60a and 61a, respectively, and the open / close valve 60a of the air supply pipe 60 is opened and the branch pipe 61 is opened during the cleaning work by the cleaning device body 10 or the like. The opening / closing valve 61a of the air supply pipe 6 is closed while the grease applying operation is performed by the application device main body 13.
0 open / close valve 60a is closed, branch pipe 61 open / close valve 6
1a is designed to be opened.

The oil supply pipe 121 is provided with a flow rate adjusting valve 121a composed of, for example, an electromagnetic valve,
The controller 70 controls opening and closing of the flow rate adjusting valve 121a.

Although not shown, a pressure sensor is arranged in the oil reservoir chamber 120 of the coating apparatus main body 13, the oil pressure in the oil reservoir chamber 120 is detected in real time, and the detected data is sent to the controller 70. It is supposed to be output. The control device 70 is configured to control the flow rate adjusting valve 121a so that the oil pressure inside the oil reservoir chamber 120 is maintained at a constant hydraulic pressure. This prevents the grease from being overcharged and prevents the grease from leaking from the applicator body 13 due to the overcharge.

Further, in the main body 13 of the coating apparatus, seal members 124 and 126 are provided on both upper and lower sides of the oil reservoir 120.
Is provided. Each seal member 124, 126 is divided in the radial direction, and each divided body is a collar 125, 12.
It is fitted in the inner surfaces of the unit bodies 100a and 100b while being held by the unit 7. As a result, at the time of maintenance, the seal member 12 is integrated with the collars 125 and 127.
It is configured so that the 4,126 can be quickly removed.

Next, the work of re-greasing the rope 5 using the cleaning oil supply device constructed as described above will be explained together with the operation of the cleaning oil supply system.

First, as a preparatory work, as shown in FIG. 1, both the device main bodies 10 and 12 are fitted and attached to the rope 5 so that the inspection device main body 12 is located above the cleaning device main body 10, and the both devices are attached. The main bodies 10 and 12 are connected to each other. The cleaning device body 10 is connected to the two device bodies 10 and 12.
The upper flange 27 and the lower flange 82 of the inspection device body 12 are connected by a connecting member such as a shackle or a bolt and nut.

Next, the moving device 14 is set and one end side of the operation wire 15 is connected to the flange 82 at the upper end of the inspection device body 12, while the other end side of the operation wire 15 is connected to the flange 26 at the lower end of the cleaning device body 10. Connect to. Then, the moving device 14 is driven to raise the cleaning device body 10 and the like, and set at a predetermined cleaning start position near the upper part 4 of the gate pillar. This completes the preparation for the cleaning work.

When the work preparation is completed, the high pressure washer 66,
The drainage pump 64, the compressor 67, etc. are started to start the supply and discharge of high-pressure hot water and the supply of high-pressure air to the cleaning device main body 10, and at the same time, the moving device 14 is driven to move both device main bodies 10 and 12 at a predetermined speed with the rope 5 Down along.

By doing so, high-pressure hot water is sprayed from the cleaning nozzles 36 to the rope 5 in the cleaning chamber 28 of the cleaning apparatus body 10, and the water pressure removes the grease adhering to the rope 5. . Then, the waste liquid containing the removed grease is drawn from the cleaning chamber 28 through the passage 42 while being sucked by the drainage pump 64, and is further sent to the oil / water separator 65 through the waste liquid pipe 58.

In the liquid removing chamber 30, high pressure air is blown onto the rope 5 from each air nozzle 46, and the waste liquid adhering to the rope 5 is removed by the air pressure. That is, along the rope 5, from the cleaning chamber 28 to the seal member 34,
The waste liquid that has passed through 35 and the like and has flowed down into the liquid removal chamber 30 is blown away and removed by this air. Then, the removed waste liquid is discharged through the passage 52 to the drainage pump 6
4 is drawn out from the liquid removal chamber 30 while being sucked by 4, and is merged from the waste liquid pipe 62 to the waste liquid pipe 58 to be combined with the oil / water separator 65.
Will be sent to.

When the high-pressure air is blown in this way, the cleaning apparatus main body 10 has the auxiliary chamber 29 formed between the washing chamber 28 and the liquid removing chamber 30, so that there is a problem caused by blowing the high-pressure air. There is a feature that can prevent. That is, when the preliminary chamber 29 is not provided, the high-pressure air discharged from the air nozzle 46 enters the cleaning chamber 28 through the passage hole of the rope 5, and as a result, the waste liquid and the like in the cleaning chamber 28 passes through the passage hole 24. It is conceivable that a phenomenon of spouting to the outside will occur through. However, according to the above-described configuration in which the preliminary chamber 29 is provided, the high pressure air does not escape into the preliminary chamber 29 and enter the cleaning chamber 28. Therefore, even if the high-pressure air is blown to the rope 5, the above-mentioned harmful effects are not brought about.

On the other hand, in the inspection device body 12, each inspection camera 86 captures an image of the rope 5, and the state of the rope 5 after cleaning is displayed on the monitor device 72 in real time.
Therefore, the operator checks the state of the rope 5 and if there is a portion where the rope 5 is not sufficiently washed, the moving device 14 is reversely driven to raise both device main bodies 10 and 12, and the portion is again cleaned. Can be washed.

At this time, since the image pickup position is displayed together with the rope 5 on the monitor device 72, for example, a place where grease cannot be completely removed or the rope 5 is not removed.
If a damage or the like is found in the disk, the position of the damage is recorded so that the subsequent repair work can be efficiently performed.

In this way, the washing operation of the rope 5 is completed by lowering the two device main bodies 10 and 12 from the washing start position at the upper end of the rope to the washing end position near the pulley 3. If necessary, both device bodies 10 and 12 may be moved back and forth a plurality of times.

After the washing of the rope 5 is completed, the operation wire 15 is removed from both device bodies 10 and 12 and both device bodies 10 and 12 are removed from the rope 5 in order to apply grease to the rope 5. As shown in FIG. 15, the applicator body 13 is attached to the rope 5, and the operation wire 15 is further attached to the flange 10 of the applicator body 13.
Connect to 4.

Then, the moving device 14 is driven to raise the coating device main body 13 and set it at a predetermined coating start position near the upper part 4 of the gate column. This completes the preparation for the grease application work.

When the preparation is completed, the opening / closing valve 61a is opened to supply high-pressure air from the compressor 67 to the oil supply device 69, thereby starting the supply of grease to the applicator main body 13. At this time, the opening / closing valve 6 of the air supply pipe 60
0a is closed.

When the hydraulic pressure in the oil reservoir 120a reaches a predetermined pressure, the moving device 14 is driven to lower the coating device main body 13 along the rope 5 at a predetermined speed. As a result, the grease supplied to the oil reservoir 120 is applied to the rope 5. At this time, as described above, the flow rate adjusting valve 121a is controlled so that the oil pressure in the oil reservoir chamber 120 is maintained at a constant hydraulic pressure based on the output of the pressure sensor, whereby the supercharging of grease is prevented and, as a result, The grease leakage from the applicator body 13 is prevented.

In this way, by lowering the applicator main body 13 from the cleaning start position at the upper end of the rope to the cleaning end position near the pulley 3, the grease application work on the rope 5 is completed. If necessary, the applicator main body 13 can be reciprocated a plurality of times along the rope 5 so that the rope 5
Alternatively, grease may be applied repeatedly.

When the grease application work is completed, the application device main body 13 and the moving device 14 are removed. This completes the work of re-greasing the rope 5.

According to the cleaning refueling system as described above,
The following effects can be obtained.

First, when cleaning the rope 5, the liquid removing chamber 30 is provided inside the cleaning device body 10 as described above.
The waste liquid that has flowed down from the cleaning chamber 28 to the liquid removal chamber 30 through the rope 5 is removed by blowing high-pressure air and is discharged to the outside. Does not flow out (leak) from the outside. In particular, since the liquid removal chamber 30 is sucked by the drainage pump 64 and the waste liquid removed from the rope 5 is positively drawn out of the liquid removal chamber, the removed waste liquid reattaches to the rope 5 and flows down. Such a phenomenon is unlikely to occur.

Therefore, as compared with the conventional cleaning device in which a sealing member is simply provided at the passage hole of the rope to prevent the leakage, the leakage of the cleaning liquid (waste liquid) can be surely prevented, which results in water pollution. There is an effect that the occurrence of can be reliably prevented.

Moreover, the auxiliary chamber 29 is provided between the cleaning chamber 28 and the liquid removing chamber 30 to allow high pressure air to escape, and the liquid removing chamber 30
Since the air pressure of the cleaning chamber 28 is prevented from acting on the cleaning chamber 28, even if high pressure air is blown to the rope 5, the adverse effect thereof, that is, the cleaning chamber 2 by the air pressure as described above.
It is possible to favorably prevent the phenomenon in which the waste liquid spouts from the outside.

In the washing chamber 28, the rope 5
On the other hand, since the high-pressure hot water is sprayed obliquely from below, this also has an effect of preventing the leakage of the waste liquid. That is, for the rope 5
Although it is possible to spray high-pressure hot water from diagonally above to diagonally below, in this case, the waste liquid flowing down along the rope 5 is urged by the high-pressure hot water discharged from the cleaning nozzle 36, and as a result, It is conceivable that the amount of waste liquid flowing down to the liquid removal chamber 30 side through the passage hole of the rope 5 increases. On the other hand, according to the configuration of the above-described embodiment in which high-pressure hot water is sprayed onto the rope 5 from diagonally below,
Not only is the waste liquid flowing down along the rope 5 not energized, but the high-pressure hot water sprayed on the contrary becomes a resistance of the waste liquid flowing down the rope 5. Therefore, the outflow of the waste liquid from the cleaning chamber 28 can be suppressed, and as a result, the effect of preventing the waste liquid from leaking to the outside of the main body of the cleaning apparatus can be enhanced.

In addition, the cleaning device body 10 is attached to the inspection device body 1.
Since the cleaning status of the rope 5 can be checked in real time by connecting the two, if there is a defective cleaning area, the area can be immediately cleaned again, and the rope 5 can be efficiently and reliably used. There is an effect that it can be washed. In particular, since the display device 90 is installed in the inspection device main body 12 so that the imaging position thereof can be confirmed on the monitor device 72, as described above, the position of the portion that cannot be washed should be recorded. By setting the position, it is possible to quickly specify the position when the worker later manually cleans the position. Therefore, the cleaning work can be efficiently performed. In addition, since the damage status of the rope 5 can also be confirmed, by recording the damaged portion, it is possible to promptly identify the position in the subsequent repair work and proceed with the repair work promptly. effective.

Further, in the main body 10 of the cleaning apparatus, an annular passage 38b is provided in the side wall thereof, and each cleaning nozzle 36 is connected to the passage 38b, and high-pressure hot water is introduced into the annular passage 38b through one passage 38a. By doing so, high-pressure hot water is distributed and supplied to each cleaning nozzle 36.
There is an effect that the high-pressure hot water can be distributed and supplied to the respective cleaning nozzles 36 with a simple configuration in which the pipes and the like are prevented from protruding outside. Similarly, with regard to the structure for supplying high-pressure air to the air nozzle 46, similarly, a simple configuration is achieved.

As for the moving device 14, the cleaning device body 10 and the like are moved by applying a driving force when the cleaning device body 10 and the like are raised and lowered as described above. Therefore, there is an effect that the work can be efficiently performed regardless of whether it is going up or down. That is, in the conventional device of this type, a driving force is applied to the cleaning device main body only when the cleaning device is raised, and the cleaning device main body is lowered by its own weight when it is lowered. The seal member that seals the sheet becomes a resistance, and the main body of the apparatus does not descend smoothly, or unevenness occurs in the descending operation, which makes it difficult to perform the work efficiently. On the other hand, according to the moving device 14, since the driving force is applied to the cleaning device body 10 and the like even when the moving device 14 descends, the cleaning device body 10 and the like can be smoothly moved regardless of whether the cleaning device body 10 is ascending or descending to perform the work efficiently. be able to.

In the moving device 14, the moving device main body 14a is fixed to the rope 5 to perform the work, so that there is no space around the rope 5 for mounting the moving device main body 14a. However, it has the effect that it can be used.

In this embodiment, the cleaning device body 10 and the like are lowered from the vicinity of the upper part 4 of the gate pillar when the rope 5 is cleaned.
The rope 5 may be washed while raising the cleaning device body 10 from the vicinity of the pulley 3, and after cleaning, the cleaning device body 10 may be removed in the vicinity of the upper part 4 of the gate pillar. This further has the following effects. In other words, in this cleaning device main body 10, high-pressure air is blown onto the rope 5 to remove the waste liquid. Therefore, if the cleaning is performed while the cleaning device main body 10 is being raised as described above, after cleaning (that is, the cleaning device main body). It becomes difficult for the waste liquid to remain on the rope 5 after passing 10). Therefore, after cleaning, the rope 5 is easily dried, and, for example, it becomes possible to quickly shift to the grease application work by the application device main body 13, and a series of grease reapplication work can be efficiently performed. There are merits. Further, there is also an effect that it is possible to effectively prevent rusting due to the waste liquid adhering to the rope 5. Needless to say, when performing the work while raising the cleaning device body 10 along the rope 5, the inspection device body 12 may be connected to the lower side of the cleaning device body 10.

By the way, the cleaning oil supply system described above is an embodiment of the present invention, and its specific configuration can be appropriately changed without departing from the gist of the present invention.
For example, the following configurations can be adopted.

(1) Instead of the inspection device main body 12, the coating device main body 13 may be connected to the cleaning device main body 10 to form a cleaning oil supply system for continuously performing the cleaning work and the grease applying work. Also, as shown in FIG.
The cleaning device main body 10, the inspection device main body 12, and the coating device main body 13 may be all connected to form a cleaning oil supply system that continuously performs cleaning work, confirmation work, and grease application work.

Further, in the cleaning oil supply system of the above-mentioned embodiment, the structure relating to the grease application such as the applicator main body 13 may be omitted. In this case, a system for only cleaning and inspecting the rope 5, that is, a cleaning / inspection system according to the present invention is configured.

(2) Cleaning device body 10 and inspection device body 1
You may employ | adopt the structure which integrated 2 and. That is, the cleaning device main body 10 and the inspection device main body 12 may be incorporated and integrated in one casing (frame). Similarly, in the case of the above (1), a structure in which the cleaning device body 10 and the coating device body 13 are integrated, or the cleaning device body 10,
A structure in which the inspection device body 12 and the coating device body 13 are integrated may be adopted.

However, if the cleaning device main body 10, the inspection device main body 12 and the coating device main body 13 are separable from each other as in the above-described embodiment, it is possible to use them properly according to the purpose and the convenience is improved. It is also advantageous in terms of storage, transportation, maintenance, etc.

(3) In the main body 10 of the cleaning apparatus, the cleaning nozzle 36 and the air nozzle 46 may be a cone type nozzle or a slit type nozzle in addition to the spot type nozzle shown in the drawing. In this case, according to the slit-type nozzle that opens all around the rope 5, high-pressure hot water or high-pressure air can be sprayed evenly around the rope 5, so that the cleaning effect can be enhanced. There are advantages. It should be noted that the nozzle type may be of any type as long as it can perform a function such as cleaning satisfactorily, and may be selected based on the results of experiments.

(4) In the cleaning apparatus body 10 described above, high-pressure hot water is sprayed as the cleaning liquid to remove (clean) the grease by the water pressure. For example, chemicals or kerosene is sprayed as the cleaning liquid to remove the grease. You may make it remove while disassembling.

(5) In the cleaning apparatus body 10, the auxiliary chamber 29 is provided to prevent the high-pressure air sprayed in the liquid removing chamber 30 from entering the cleaning chamber 28 through the passage hole of the rope 5. However, the spare chamber 29 may be omitted if there is no risk of high-pressure air entering the cleaning chamber 28, or if there is no risk of waste liquid being blown out even if the high-pressure air enters the cleaning chamber 28. Instead of providing the auxiliary chamber 29, a passage (a passage different from the waste liquid discharge passage 52) that directly communicates the liquid removing chamber 30 with the outside of the cleaning apparatus main body 10 is provided so that the inside of the liquid removing chamber 30 is provided. The gas pressure may be released to the outside. Even with such a configuration, it is possible to prevent the high pressure air from entering the cleaning chamber 28. In this case, the passage may be formed in a labyrinth shape or the passage may be sucked to prevent the waste liquid from leaking to the outside through the passage.

(6) In the above embodiment, the rope 5 in the vertical direction is washed by the washing device body 10, but the rope 5 in the horizontal direction or a direction close thereto can be washed by the washing device body 10. Is. In this case, for example, when the horizontal rope 5 is targeted, the liquid removing chambers 30 may be provided on both sides of the cleaning chamber 28 (that is, both sides in the longitudinal direction of the rope 5) in the cleaning device body 10. Good.

When the rope 5 in the horizontal direction or a direction close to the horizontal direction is to be cleaned, for example, as shown in FIG.
You may make it comprise the washing | cleaning apparatus main body 10 'as shown in FIG. Hereinafter, the cleaning device body 10 'will be described. The same parts and members as those of the cleaning device body 10 are designated by the same reference numerals, and detailed description thereof will be omitted.

The cleaning apparatus body 10 'shown in the figure also has an elongated cylindrical shape, and the passage holes 24 for the rope 5 are provided at both ends thereof. A cleaning chamber 28 partitioned by a pair of partition walls 130 is formed inside the cleaning device body 10 ′, and a cleaning nozzle 36 is provided in the cleaning chamber 28.

Sealing members 132 are attached to the partition walls 130 that form the cleaning chamber 28, respectively, so that the partition wall 130 and the rope 5 are sealed to seal the cleaning chamber 28. There is. The seal member 13
As the member 2, a member having the same V-shaped cross section as that of the seal members 34 and 35 shown in FIG. 4 is adopted, and it is configured so as to be able to cope with the diameter variation of the rope 5 to some extent.

Further, of the passage holes 24, the brushes 134 are provided, for example, over the entire circumference of the passage holes 24 on the leading side (that is, the leading side when the cleaning apparatus body 10 'is moved during washing). It is provided so that the deposits on the rope 5, for example, a mass of hardened grease can be removed prior to cleaning. On the other hand, the passage holes 24 on the opposite side are provided with air nozzles 46 at regular intervals, and are configured to blow high-pressure air onto the rope 5.

At the time of cleaning, the cleaning device main body 10 'is moved in the direction of the arrow in the figure (beginning with the brush 134 side) while discharging high-pressure hot water from the cleaning nozzle 36 and high-pressure air from the air nozzle 46, respectively. Thus, the brushes 134 are first used to remove the deposits on the rope 5, and then the high-pressure hot water is used for cleaning, and then the waste liquid attached to the ropes 5 is removed by the high-pressure air.

That is, when the horizontal rope 5 is targeted, the waste liquid does not flow down along the rope 5 as in the case where the vertical rope 5 is targeted. Even a simple seal member 132 such as 10 'can prevent the leakage of waste liquid.
Therefore, in the cleaning device main body 10 ', the auxiliary chamber 29 and the liquid removing chamber 30 like the cleaning device main body 10 shown in FIG.
The air nozzle 46 is configured to be left in the passage hole 24 so that the waste liquid adhering to the rope 5 can be removed, while the construction is simplified by omitting it.

(7) In the system described above, the display device 90 is installed inside the inspection device body 12, and the display of the display device 90 is imaged by the inspection camera 86 so that the image pickup position of the rope 5 is displayed on the monitor device 72. Although it is displayed, the imaging position obtained by the control device 70 may be directly displayed on the monitor device 72, for example. By doing so, the display device 90 is not required, so that the inspection device main body 12 can be made simple and compact.

(8) In the above embodiment, the cleaning device body 10 and the inspection device body 12 are connected to each other so that the cleaning work and the inspection work can be performed continuously. The cleaning operation and the inspection operation may be independently performed while replacing the cleaning apparatus main body 10 and the inspection apparatus main body 12 with respect to the apparatus 14.

(9) As the moving device 14, a moving device as shown in FIG. 18 may be adopted. The moving device 14 will be described below.

Then, the cleaning device main body 10 can be forcibly stopped from moving by bringing it into contact with the side surface of the sprocket 146.

According to such a moving device 14, as shown in FIG.
The number of parts is smaller than that of the moving device 14 shown in FIG. 1, and the work such as fixing the moving device body 14a to the rope 5 with the fixing metal fitting 92 is not necessary, so that workability at the time of installation is also improved. There is. Although not specifically described, power supply and control to the movable device 142 may be performed by wire. For example, a battery is mounted on the movable device 142 and drive control is performed wirelessly. It doesn't matter.

(10) In this embodiment, an example in which the cleaning oil supply device of the present invention is used for re-greasing work of the wire rope for opening and closing the river gate is described, but this cleaning oil supply device is not Of cranes, elevators,
