Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refueling device for wire ropes for opening and closing dams, river gates, etc., or wire ropes for cranes, elevators, ropeways, etc.

[0002]

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 used for the purpose of rope protection, rust prevention and lubrication, etc. , Grease or the like), and the grease or the like is reapplied at regular intervals (for example, every 2 to 3 years).

Conventionally, this kind of work relies on human work, but there is a problem that workability is extremely poor due to work in unstable high places, and there is a danger. Work is performed using a remote-controlled oil supply device.

The oil supply apparatus has, for example, a hollow main body having an oil storage chamber inside, and the main body is fitted onto the rope and moved along the rope so that the oil storage chamber is moved toward the oil storage chamber. The grease is applied while passing the rope.

[0005]

In such a coating operation, it is ideal that grease or the like is coated in a thin coating on the surface of the rope. That is, if extra grease or the like is applied, it may cause environmental pollution due to dropping into the sea or lakes, and it may be difficult to reapply the grease next time due to hardening of the grease due to deterioration or the like. Further, if there are spots, there is a possibility that a sufficient rust prevention effect or lubrication effect may not be exhibited.

With respect to this point, in the conventional oil supply device of this type, since a seal member for sealing between the oil reservoir and the rope is generally provided, the oil drain effect (unnecessary grease etc.) is provided to some extent by the seal member. Is effective). However, when the applied material has a high fluidity, its effect is low, and it is difficult to apply grease or the like evenly between the strands forming the rope, and there is room for improvement in these points. There is.

The present invention has been made in view of the above problems, and an object of the present invention is to provide an oil supply device for a wire rope which can apply grease or the like more favorably.

[0008]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention is directed to an oil inside the device body by relatively moving the device body externally fitted and attached to the wire rope along the wire rope. In a wire rope lubricator that applies oil while passing the wire rope through the reservoir,
A gas nozzle that blows a gas onto the wire rope coated with the oil passing through the oil reservoir is provided in the apparatus main body (claim 1).

According to this oil supply device, after the oil such as grease is applied to the wire rope, the excess oil is removed by blowing the gas from the gas nozzle onto the wire rope, and the oil on the surface of the wire rope is also removed. Diffusion and penetration of oil between the strands that make up the rope will be facilitated. Therefore, as compared with the case where the wire rope is simply passed through the oil storage chamber, it is possible to apply the oil to the wire rope satisfactorily without excess or deficiency.

In this oil supply device, it is preferable that a plurality of gas nozzles are provided so as to surround the wire rope (claim 2).

According to this structure, it is possible to blow the gas evenly around the entire circumference of the wire rope, and the above-described action of removing excess oil and the action of diffusing and penetrating oil are good for the entire wire rope. You will be able to get to.

Further, it is more preferable that the gas nozzle blows gas at an angle inclined toward the oil reservoir with respect to the direction orthogonal to the longitudinal direction of the wire rope (claim 3).

According to this structure, it is possible to prevent the oil removed by the gas pressure from scattering outside the apparatus main body.

In the above oil supply apparatus, it is preferable that the apparatus main body is provided with a brush for removing excess oil of the wire rope prior to blowing the gas (claim 4).

By thus removing the excess oil with a brush in advance, it is possible to satisfactorily remove the oil having a particularly high viscosity (excess oil). In addition, by removing the excess oil in advance, it is possible to prevent the excess oil from scattering when the gas pressure acts.

0 is shown schematically. As shown in these figures, the device body 10 includes a wire rope 1 (hereinafter abbreviated as rope 1).
Has a slender cylindrical shape in the axial direction (hereinafter, referred to as the left-right direction), and the passage holes 12 of the rope 1 are provided at both left and right ends thereof. Further, on the outer peripheral surface of the apparatus main body 10 at both left and right ends, there are provided connection flanges 14 for driving a device (not shown) for driving the apparatus main body 10. In addition,
These flanges 14 are omitted in drawings other than FIG.

The apparatus main body 10 is composed of two unit main bodies 20a and 20b which are divided in the radial direction. The rope main body 10 is integrally fitted with bolts and nuts with the rope 1 sandwiched between the main bodies 20a and 20b. It is configured to be.

More specifically, the unit bodies 20a, 2
0b includes a plurality of coupling flanges 22, which correspond to each other.
24 are formed side by side in the left-right direction, and the flange 2 on one side is formed.

The flange 24) has a U-shaped groove 28 formed therein. Then, sandwiching the rope 1, both unit bodies 20a,
20b are overlapped with each other, and the bolts 26 are inserted in the grooves 28.
Both the flanges 22 and 24 are overlapped with each other with the interposing, and in this state, the wing nut 30 is fastened to the bolt 26 from the opposite side of the flange 24 (upper side in FIGS. The device body 10 is attached to the rope 1 by integrally connecting the 20b.

In the following description, for convenience, the unit main bodies 20a and 20b are not particularly distinguished except when necessary (that is, the cleaning device main body is based on the state in which the unit main bodies 20a and 20b are connected). 10 will be explained).

FIG. 3 shows the internal structure of the apparatus body 10. As shown in this figure, a cylindrical oil reservoir chamber 32 is defined inside the apparatus body 10, and the rope 1 penetrates the oil reservoir chamber 32 in the left-right direction.

Substantially cylindrical seal members 34 and 35 are attached to the partition walls at the left and right ends of the oil reservoir 32, respectively.
As a result, the space between each partition wall and the rope 1 is sealed. Each of the seal members 34, 35 is formed in a V-shaped cross section that opens toward the radial center of the apparatus body 10 (toward the rope 1 side) as shown in FIG. Also, it is configured so that the sealing effect can be exhibited. It should be noted that each of the seal members 34 and 35 is a unit main body 20.
It has a divided structure corresponding to a and 20b, and is configured to have a cylindrical shape in the united state of both unit main bodies 20a and 20b.

The oil reservoir chamber 32 is connected to an oil supply machine (not shown) through a supply pipe 2 (shown in FIGS. 1 and 2) connected to the apparatus body 10, and is supplied from the oil supply machine at the time of work. The oil is supplied to the oil reservoir 32 through the pipe 2. An oil pressure sensor, for example, is provided in the oil sump chamber 32, and during work, the amount of oil supplied to the oil sump chamber 32 is adjusted (controlled) based on the pressure detected by the oil pressure sensor. , Is configured to prevent excessive supply of oil.

A brush 36 and an air nozzle 38 (gas nozzle) are provided in this order inside the apparatus main body 10 on the right side of the oil reservoir 32 along the rope 1.

The brush 36 is a brush made of synthetic fiber or the like, which is provided so as to face the entire circumference of the rope 1, and is provided so as to come into contact with the surface of the rope 1 after oil application.

On the other hand, the air nozzle 38 (gas nozzle) is
High-pressure air (gas) supplied from a compressor (not shown) through a supply pipe 3 (shown in FIG. 1) is blown onto the rope 1 after oil application. In this embodiment, the rope 1
A plurality of air nozzles 38 are arranged at equal intervals in the circumferential direction along the inner wall surface of the apparatus main body 10 so that the air can be uniformly blown over the entire circumference of the apparatus. Note that, as shown in FIG. 3, each air nozzle 38 is configured to blow gas onto the rope 1 at an angle θ slightly inclined toward the oil reservoir 32 side with respect to the direction orthogonal to the longitudinal direction of the rope 1. Has been done.

In order to apply the oil to the rope 1 using the above oil supply device, first, as a preparatory work, the device body 10 is externally fitted to the application start position of the rope 1 and the device body 10 is driven. As a device, it is connected to, for example, a winch arranged at the application end position. Device body 10 to rope 1
As shown in FIG. 3, the mounting is performed so that the oil reservoir chamber 32 is located at the head, that is, the application end position side, and the air nozzle 38 is located at the opposite side. Further, the winch is connected by connecting the wire drawn out from the winch to the connecting flange 14 using a connecting tool such as a shackle.

When the preparation is completed, the oil supply machine is operated to start the oil supply to the apparatus main body 10 and the compressor is driven to start the supply of the high pressure air to the air nozzle 38. When the hydraulic pressure in the oil reservoir 32 reaches a predetermined pressure, the winch is driven to move the device body 10 along the rope 1 at a constant speed.

In this way, the rope 1 is moved to the oil reservoir 32.
The oil is applied to the rope 1 as a result. At this time, the brush 36 comes into contact with the rope 1 that has passed through the oil reservoir 32, so that the excess oil applied to the rope 1 is removed. Then, by further blowing high-pressure air from the air nozzle 38 onto the surface of the rope 1, the surplus oil is further removed, while the oil is diffused on the rope surface and the oil permeates between the strands forming the rope 1. Will be promoted.

Note that the oil removed by the brush 36 is the gap 3 provided between the oil reservoir chamber 32 and the brush 36.
7 is introduced, and as a result, oil leakage to the outside is prevented. Further, as described above, the air nozzle 38 is provided so as to blow the air at the inclined angle θ toward the oil storage chamber 32 side, so that the oil removed by the air pressure is also prevented from being scattered outside. Has become.

After moving the apparatus body 10 to the coating end position in this way, the winch is removed from the apparatus body 10,
Further, the device body 10 is removed from the rope 1. This completes the oil application work on the rope 1.

According to such an oil supply apparatus, after the oil is once applied to the rope 1 as described above, the excess oil is removed by the brush 36, and high pressure air is further blown to diffuse the oil in the rope direction and the strands. Since it is configured to promote penetration into the rope 1, the oil can be applied to the rope 1 without excess or deficiency, that is, in a state where the oil is thinly coated on the surface of the rope. Therefore, the oil can be applied to the rope 1 in a more ideal state (satisfactorily) as compared with the conventional device of this type that simply passes the rope through the oil reservoir.

By the way, the oil supply apparatus described above is one embodiment of the oil supply apparatus according to the present invention, and is the apparatus main body 1
The specific configuration and the like of 0 can be appropriately changed without departing from the gist of the present invention.

For example, the brush 36 may be omitted to simplify the structure. In other words, the effect of removing excess oil is also exerted by blowing high-pressure air from the air nozzle 38, and therefore the brush 36 can be omitted and the configuration can be simplified. However, if the brush 36 is provided to remove the excess oil in advance, the excess oil is less likely to be scattered due to the blowing of the high pressure air, which is effective in more surely preventing oil leakage to the outside. is there. In addition,
When applying grease or the like having a viscosity higher than that of oil as the application oil, the excess grease may not be removed sufficiently by air pressure alone. Therefore, even in such a case, the brush 36 is effective. Become.

Further, in this embodiment, the oil removed by the brush 36 is stored in the gap 37 in the apparatus main body 10 to prevent the oil from leaking to the outside. For example, the oil is collected in the gap 37. The oil may be recovered by forcibly sucking it through the recovery pipe. According to this, it is possible to reliably prevent oil leakage to the outside. Similarly, the brush 36
The oil removed by the air pressure may be recovered by sucking the gap between the air nozzle 38 and the air nozzle 38.

In this embodiment, the rope 1 stretched in the horizontal direction or a direction close to the horizontal direction is targeted, but the oil supply device of the present invention is targeted at the rope 1 stretched in the vertical direction. Of course, it can also be applied as an oil supply device. In this case, the seal structure may be strengthened so that the excess oil can be reliably prevented from leaking to the outside, and the suction mechanism in the apparatus body 10 described above may be used together.

[0037]

As described above, the oil supply device of the present invention is provided with the gas nozzle in the main body of the device and removes the excess oil by blowing the gas to the wire rope which has passed through the oil reservoir chamber. Since it is configured to promote the diffusion of oil on the surface of the rope and the penetration of oil into the strands, it is possible to apply the oil to the wire rope without excess or deficiency. Therefore, the oil can be applied better than the conventional device of this type, which simply passes the wire rope through the oil reservoir.
