The brush body 20 is arranged so that the brush body 20 is rotated while contacting with the cable 2 by inserting the cable 2 into the brush body 20.

Description

  The present invention relates to a cable cleaner that removes deposits such as oil and dust adhering to a cable.

  Conventionally, as a cable cleaner, there is known a cleaner that removes dirt such as dust attached to the surface by sandwiching the cable between sponges or brushes and pulling the cable (see, for example, Patent Document 1). . However, this cable cleaner is mainly used for household cables, and is not a cleaner used for electric wires such as underground cables and bypass cables.

  FIG. 8 is a diagram showing a state when a conventional underground cable is removed. As shown in FIG. 8, when the underground cable was removed, the operator directly gripped the cable and pulled it from the ground (underground) to the ground. A lot of deposits such as a lubricant applied during laying and dirt attached during laying are attached to the cable. In this case, since it is determined whether or not the cable can be reused, it is difficult to determine whether or not there is an adhering substance when an appearance inspection is performed.

  Therefore, at present, when an operator pulls out the removal cable, an appearance inspection is carried out while wiping off the adhered material with a waste cloth (cloth used for oil wiping or the like). On the other hand, even when the bypass cable was stored, the adhering matter adhering to the cable was wiped off with a waste cloth and wound around the storage drum. In any case, the dirt on the cable was manually wiped off with the waste cloth.

JP 2002-101513 A

  However, when a conventional underground cable is removed or when the bypass cable is stored, the attached matter of the cable is wiped off with a waste cloth. Also, the work of pulling out and wiping the cable places a burden on the operator and causes a delay in the removal work. In particular, since the cable itself is dirty and slips, as shown in FIG. 8, there is a risk of an operator falling accidentally because the cable slips with difficulty in pulling and winding the cable. In addition, when wiping a long cable, a large amount of waste is required, so that there is a problem that waste to be discarded increases.

  Therefore, an object of the present invention is to provide a cable cleaner that allows an operator to work safely without using a waste cloth and that can reliably remove contaminants such as dirt simply by inserting a cable.

  In order to solve the above-mentioned problems, the invention of claim 1 is a cable cleaner that removes deposits such as oil and dust adhering to a cable, and includes a cylindrical rotating body and an inner peripheral surface of the rotating body. A brush body that can be inserted into the cable and removes the adhering matter, and a support body that is cylindrical and supports the rotating body so as to be rotatable about the axis in the cylinder. The cable cleaner is characterized in that the brush body is disposed so that the brush body rotates while being in contact with the cable by inserting the cable.

  According to the present invention, the support is fixed, and the cable is inserted and pulled through the brush body in the rotating body, so that the brush is independently rotated along with the rotating body along with the cable, such as oil or dust attached to the cable. Deposits are removed.

According to the first aspect of the invention, the following effects can be obtained.
1. Reduced worker burden Since it is possible to remove deposits by simply pulling the cable with a cable cleaner attached, it prevents slipping of the hand due to the sliding material and reduces the burden on the worker compared to the removal work with a conventional waste cloth. I can expect that. As a result, the work efficiency of underground cable removal and bypass cable storage can be significantly improved.
2. Improvement of work safety Since the attached matter is removed simply by passing the cable through the cable cleaner, it is possible to work in a stable posture when the cable is pulled out or wound. As a result, it is possible to expect effects such as preventing the worker from falling.
3. Improvement of work quality Since the brush body is rotated independently with the rotating body while being in contact with the cable, the adhered matter is removed, so that the adhered matter in the gap can be reliably removed even with a cable such as a stranded wire. As a result, the ability to remove dirt is improved, and the removed cable can be easily reused (damage of the removed cable can be easily confirmed).
4). Since the amount of waste attached to the cable is removed only by rotating the brush, a large amount of waste is not required. As a result, it is possible to expect a small amount of garbage to be discarded.
5. Application to other fields Because of the simple structure of passing a cable through a cable cleaner, it is not limited to electric wires such as underground electric cables and overhead electric wires.

  The brush 22 has an opening diameter 22 a into which the cable 2 is inserted at the center, and the opening diameter 22 a is slightly smaller than the outer diameter of the cable 2. That is, at the opening diameter 22a of the brush 22, the rotational force along the spiral shape is transmitted by friction while the cable 2 is inserted and brought into contact therewith. Then, the rotational force of the brush 22 is transmitted to the rotating body 10, and the rotating body 10 rotates independently with the brush 22.

  Further, as shown in FIG. 2, the brush body 20 has a rough brush 22A at both ends in the hollow of the rotating body 10, and a fine brush 22B at the center. That is, when the cable 2 is inserted, the coarse and large deposits are removed at the front and rear in the insertion direction, and the fine deposits are removed at the center, thereby increasing the strength of the removal force. Thereby, the deposit | attachment adhering to the cable 2 is removed efficiently.

  On the other hand, as shown in FIG. 1, the support body 30 includes a housing body 31 that houses the rotating body 10, a bearing 32 that is fixed within the housing body 31 and rotatably supports the rotating body 10, and a housing body. And a lid 33 that closes the opening of 31.

  The container 31 is cylindrical and has one hollow end opened so that the rotating body 10 can be inserted into the cylinder. On the other end side, the rib 31a protrudes from the outer periphery so that the rotating body 10 does not come out, and the center is opened so that the cable 2 can be inserted. In addition, a plurality of bearings 32 (three in FIG. 1) are arranged in the housing 31 at a predetermined interval, and the rotary body 10 is rotatably supported around the axis. In addition, the container 31 is sealed so that the rotating body 10 does not come out from the inside by forming a screw portion 31d on the outer periphery of one end of the opening into which the rotating body 10 is inserted and screwing the lid 33. Yes.

  The lid 33 is formed by a cylindrical peripheral wall 33a that is screwed into the threaded portion 31d of the container 31, and a rib 33c that covers one side of the peripheral wall 33a and opens a hole 33b in the center. The peripheral wall 33a is formed with a screw portion 33d on a cylindrical inner peripheral surface so as to be screwed with the screw portion 31d of the container 31. The rib 33c extends from the cylindrical end of the peripheral wall 33a so as to cover the opening surface, and a hole 33b is opened in the center so that the cable 2 can be inserted. When such a lid 33 is screwed into the container 31, as shown in FIG. 2, both ends of the rotating body 10 are supported by the rib 31a of the container 31 and the rib 33c of the lid 33. The rotating body 10 is held in a freely rotatable state by the bearing 32.

  Next, the operation of removing the deposits on the cable 2 using the cable cleaner 1 having such a configuration will be described in detail with reference to FIGS. FIG. 4 is a diagram illustrating an operation of removing the deposit by the cable cleaner 1 of FIG. FIG. 5 is a diagram showing the state of the cable 2 inserted into the brush body 20 of FIG. 2, wherein (a) and (c) show the state with the coarse brush 22A, and (b) show the fine brush. Each of the states at 22B is shown. First, as the cable cleaner 1, the rotating body 10 is accommodated in the accommodating body 31 shown in FIG. 1, and the lid 33 is screwed, so that the order of roughening, fineness, and roughening shown in FIG. The brush body 20 provided with the brushes 22A and 22B is set.

  The cable cleaner 1 assembled in this way is used by being provided with an installation base 3 in the vicinity where an operator pulls out the cable 2 from the ground (underground) as shown in FIG. Is done. At this time, even if the installation table 3 is not arranged, for example, one of the workers can hold the cable cleaner 1 and the other person can pull the cable 2. Here, an embodiment using the installation table 3 will be described below.

  Next, with the cable cleaner 1 (support 30) fixed to the installation base 3, the tip of the cable 2 drawn from the ground (underground) is connected to the cable cleaner 1 (inside the brush body 20: see FIGS. 2 and 3). To be inserted.

  Thereafter, the worker pulls the cable 2 that has passed through the cable cleaner 1 on the ground (on the ground), whereby the deposits attached to the cable 2 can be removed. At this time, the cable 2 is sent to the worker side in a state where the deposits are removed via the cable cleaner 1. This prevents the operator from slipping or falling due to the deposits, so that the worker can work in a stable posture.

  Here, as shown in FIGS. 5A and 5C, the cable 2 inserted through the cable cleaner 1 is first removed from the large adhering matter adhering to the outer periphery with a coarse brush 22A. Next, when the operator pulls the cable 2 as shown in FIG. 4, as shown in FIG. 5 (b), the fine brush 22B finely enters the gap between the wires such as a stranded wire. Extraneous matter is removed. Finally, the large adhering matter is removed again by the coarse brush 22A shown in FIGS. 5A and 5C, so that the adhering matter adhering to the cable 2 is completely removed.

  As shown in FIG. 2, the removal of the deposits in the cable cleaner 1 is performed by inserting the cable 2 and pulling it to transmit the rotational force to the spiral brush body 20 along the cable 2. Therefore, it rotates independently with the rotating body, and deposits such as oil and dust adhering to the cable 2 are removed. In other words, in the present embodiment, the rotational force is transmitted to the brush body 20 only by inserting / removing the cable 2 without using any additional power for removing the deposits, and the operation is performed.

  Then, when all the cables are pulled out from the ground (underground) shown in FIG. 4 via the cable cleaner 1, the underground cable removal work is completed. Thereafter, the cable cleaner 1 can be used again at other sites by removing the deposits attached to the brush body 20 by removing it from the installation table 3. At this time, as shown in FIG. 1, the cable cleaner 1 can easily take out the rotating body 10 by removing the lid 33 from the housing 31, and easily remove the adhering matter attached to the brush body 20. Can be removed.

As described above, according to the cable cleaner 1, the following effects can be obtained.
1. Reducing the burden on the operator By attaching the cable cleaner 1 and pulling the cable 2 to remove the deposits, compared to the conventional removal work using waste cloth, it prevents slipping of the hand due to the lubricant and reduces the burden on the operator. It can be expected to reduce. As a result, the work efficiency of underground cable removal and bypass cable storage can be significantly improved.
2. Improvement of work safety Since the adhering matter is removed simply by passing the cable 2 through the cable cleaner 1, it is possible to work in a stable posture when the cable 2 is pulled out or wound. As a result, it is possible to expect effects such as preventing the worker from falling.
3. Improvement of work quality Since the brush body 20 rotates independently with the rotating body 10 while being in contact with the cable 2, the adhering material is removed, so that the adhering material in the gap can be reliably removed even with the cable 2 such as a stranded wire. As a result, the ability to remove dirt is improved and the removal cable 2 can be easily reused (damage of the removal cable 2 can be easily confirmed).
4). Since the amount of waste attached to the cable 2 is removed only by the rotation of the brush body 20, a large amount of waste is not required as in the prior art. As a result, it is possible to expect a small amount of garbage to be discarded.
5. Application to other fields The simple structure of passing the cable 2 through the cable cleaner 1 is not limited to electric wires such as underground cables or overhead cables. it can.
